During the Blister Machine is running, the upper sealing mould (15) will be in it's lowest position driven by heat sealing cylinder, the sealing temperature shall reach 160℃. When lower sealing mould move downward, the upper and lower mould seprate, the formig material (now have blister cavities filled with products) and lidding foil are dragged into the sealing station, lower sealing mould will be rise up driven by sealing cam (5), thus upper sealing mould (15) and lower sealing mould (12) closed, the adhesive side of the lidding material is affixed to the forming material by the heat and pressure, the products are contained between the blister cavities and lidding foil. When lower sealing mould move downward, the sealed web move forward ready for embossing and cutting. When the Blister Machine stops, the upper sealing mould can rise up automatically, to prevent hot air from getting into the blister pockets, so that medicine (or other goods) effectiveness is preserved.

DPP260 series Blister Packaging Machine cold-forming mould installation: The working principle of the cold-forming station in the Blister Machine. When the Blister Machine is working, the forming cam drive the forming lower mould (18) upward to press the aluminum film tightly between the press plate (12) and lower forming mould (18), meanwhile the cover plate (14.2) was driven by the eccetric wheel (1) to move downward. The punch dies (16) which was installed in the cover plate will elongate the aluminum film to form the blister cavity. The forming depth of the blister cavity can be adjusted by the nuts (13) and (15). Installation. Use the hand barring gear to run the Blister Machine to its highest position (the forming cam at the highest position). Putting the lower forming mould (18) on the forming station, screw the nuts (11.1) into each of the four forming column (9.2), install the press plate (12), adjust the nuts (11.1) downward let the press plate touch the lower forming mould, screw the nuts downward more untill the gap between the naus and the press plate is about 1-2mm.  Putting butterfly washer (21) (two pcs for each column) and another set of nut (11.2), to insert the positioning pin (19) into the press plate and forming lower mould to make sure the lower mould position is aligned with press plate, fix the forming lower mould by screw, then take the positioning pin (19) out, screw the nuts (11.2) downward to press the butterfly washer (21) but not tightly at this step. Install the forming punches mould (16), nuts (15) and the forming cover plate (14.2), lastly install nuts (13), but do not fasten them at this step. Testing the cold-forming station: Use the hand barring gear to run the blister machine to its lowest position, let the aluminum film enter into the forming station, screw the nuts (11.2) downward to press the butterfly washer (21) create pressure between the press plate (12) and lower forming mould (18), fasten the aluminum film tightly.  Use the hand barring gear to run the Blister Machine to its highest position and the punch ties pushed into the aluminum film.  During the testing of the Blister Machine, need to adjust the pressure between the press plate (12) and lower forming mould (18), need have enought pressure to press the aluminum film tightly, so the punch die can elongate the film and form the blister pocket, always try to use less pressure to form the blister properly becaure larger pressure is harmful for the Blister Machine, when adjustment is finished screw the nuts (11.1) upwards to fasten the press plate (12). During testing the Blister Machine need to adjust the nut (13) and (15) to control the forming depth of the blister cavity, the forming depth of the aluminum film is limited, too deep elongation will break the film or make some tiny pin hole, it is not easy to inspect by naked eye, so be aware of this, after adjusting the forming depth fasten the nuts (13) and (15).  The schematic diagram of DPP series Blister Machine's cold-forming station.  

Changeover between thermoforming and cold-forming station in DPP series Blister Machine. The standard of our Blister Packing Machine is equipped with thermoforming station. When customer need to produce cold-forming blister packaging, they need to purchase change parts and cold-forming mould from our company. The way to install the change parts for cold-forming are as following: 1.Install Eccentric wheel case (3) Connect the Eccentric wheel case (3) with the camcase (7) by the four screw on small column (28). The eccentric wheel case (3) was already equipped with eccentric wheel (1), connecting rod (4) and small column (28). 2.Change forming column (9.2) Remove the thermoforming-forming cover plate (14.1) and thermoforming-forming column (9.1), then install the cold-forming column (9.2). 3.Install tie rod (26) To insert the tie rod (26) through the camcase(7) from up to bottom, fix the two tie rod with the connecting-rod (4). 4.Install the lower forming mould (18) Use the hand barring gear to run the blister machine to its highest position (the forming cam at highest position), remove the thermoforming-forming lower mould from the lower mould guide plate (23). Put on the baseboard (10), forming lower mould (18) and pressing plate (12). To insert the positioning pin (19) into the press plate and forming lower mould to make sure the lower mould position is aligned with press plate, fix the forming lower mould by screw, then take the positioning pin (19) out. 5.Install the upper forming mould Install punches (16) on the pressing plate (12) one by one then put the forming cover plate (14.2), the connect the forming cover plate with the tie rod (26). To adjust the height position of the forming cover plate can change the forming depth of the blister pocket, we will talk about the adjusting at next page.  6.Installing chain 29: To connect the main spline shaft (27) and shaft (30) by chain. When install the chain, need to adjust and correct the eccentric wheel's angle position with the forming cam, make sure when the forming cam drive the forming lower mould (18) up to touch the press plate(12), the eccentric wheel will drive the forming punches (16) down to elongate the aluminum film and form the blister properly.  The schematic diagram of DPP series Blister Machine's thermoforming and cold-forming station.  

In blister packaging, for some light and moisture-sensitive drugs, the protective properties of the PVC may not strong enough, because of the PVC's poor barrier against moisture ingress, oxygen ingress and transparent character. In order for better protection and extend product expiration date, Blister Packaging Machine can choose Aluminum/aluminum packaging, also is called the cold forming blister packaging.  In the blister cold forming process, an aluminum film is simply pressed by a plug, similar with "plug-assist" feature in thermoforming blister packaging. The aluminum film will be elongated and maintain the formed shape. The principal advantage of cold forming blister packaging is that the use of aluminum offers a nearly complete barrier for water and oxygen, allowing an extended product expiration date. The principal disadvantages of cold forming blister packaging are: the slower speed of production compared to thermoforming blister packaging; the lack of transparency of the package; and the larger size of the blister card (aluminum cannot be formed with near 90 degree angles). The following is our DPP series Blister Packaging Machine's cold forming structure. When aluminum film is dragged into the forming position in Blister Machine, the forming lower mould (18) will move up by the forming cam (5) to press the plate (12) to fix the aluminum film. Meanwhile the forming plugs (16) which are installed on the upper mould (17) will move down driving by a eccentric wheel (1), then the blisters was formed. After filling, the formed aluminum blisters will then arrive at Blister Machine's sealing station to seal with lidding aluminum foil, so in blister packaging industry these blisters packaging are also called alu-alu pack.

DPP series Blister Machine forming station working principle When the Blister Machine running the forming material (pvc) is unwound from the reel and enter into heating station on the blister machine. The temperature of the heating plates (upper and lower plates) is such that the pvc will soften and become pliable. The warm pvc will then arrive in a forming station, when the upper and lower mold close, a large air pressure (4 to 8 bar) will form the blister cavity from the forming lower mold. When the blister is cooled the pvc becomes rigid again and maintains its shape when removed from the mold. In cases of difficult or larger shapes, the Blister Machine will adopt "plug-assist" mechanism, the warm PVC will be physically pushed down partially into the cavity by a plug. Plug-assist results in a blister cavity with more uniform wall distribution. Blister Machine forming lower mold installation method Before installation, please check the exhaust hole of forming lower mold is flowing, no block (if the hole is blocked, blister can not be formed properly). Our DPP260Ki2 Blister Machine adopts a cylinder to lock the lower forming mold in forming station, the valve to control the cylinder is installed below the forming station, before install the lower mold, turn the valve clockwise to make the locking mechanism in loosened position. Screw the handle (15) into the lower mold's threaded hole. Making the T-slots of lower mold aimed at the cylinder piston then pushing forward. Turn the valve counterclockwise to lock the lower mold. Blister Machine forming upper mold installation method Before installation, please check the huffing hole of forming upper mold is flowing, and the sealing silicon ring is not damaged (make sure no air leakage during forming process). Loosen upper mold fix bolt (11), screw the handle (15) into the upper mold's threaded hole, aimed at the groove and pushing forward, then fasten the upper mold fix bolt (11) to lock upper mold.     The schematic diagram of the Blister Machine's forming station  

The device can heat and intenerate the material(PVC). After the material(PVC) enter into the forming station, the blisters are formed by compressed air. The working principle as following: First, through the control interface set the forming temperature and compressed air blow time. Different forming material ( PVC) have different thickness. According to differences of forming shape, size and deepness, the machine need different working temperature. Common material (PVC) of 0.25mm thickness, setting the temperature at 105-110℃ usually. When the Blister Machine running the lower heat pate moving up and down, it makes the upper and lower heat plate open and close repeatedly. When the upper and lower heat plate closed, the material (PVC) is intenerated. When the upper and lower heat plate open, the material (PVC) is dragged to the forming station.

After the material replacement you run the Blister Machine again. The schematic diagram of the Blister Machine's forming material splicer

As the Blister Machine running, the changing of forming material is very frequent, for more convenient and efficient changeover of PVC, this Blister Machine set up two forming material reel stations, the outer① and  inner material reel station. During the Blister Machine running, the outer material reel will become small in diameter, then put the small reel in inner material station, put the new PVC reel in the outer material station for standing by. By loosen Fast-fixed screw⑧ to adjust Fixing ring⑨ to change the PVC reel location. Equipped with a sensor, when forming material run out or broken a alarm will be raised, the Blister Machine will stop automatically. If using PVDC as forming material please make sure the gummed side is upward for sealing with alum foil.  

 DPP series Blister Machine drive principle The Blister Machine's reducer is dragged by main motor and it makes spline main shaft running, Forming cam, heat sealing cam, printing batch number cam, perforation cam and cutter eccentric wheel all install on the spline main shaft separately. Each cam(cutter station is eccentric wheel) impulses each working station up and down running to finish the forming, heat sealing, printing batch number,perforation and cutting process for the packing materials. Each working station of the Blister Machine can adjust left or right positi on through the relevant adjustment orientation hand wheel except heat sealing working station.  The purpose is to insure that the mould of each working station is consistent with the blister or the pallet position. The roller dragging length mechanism of this type of Blister Machine is droved by servo motor. The general working principle of the Blister Machine as following: While each working station cam rise, the mould close. And the mould of each working station finish forming,heat sealing, printing batch number, perforation and cutting progress for the materials. At this time, the dragging length mechanism stop. While each working station cam decline, the mould open. At this time the dragging length mechanism begin to drag the materials till the end position. Then each woring station can rise again,The Blister Machine go round and round like this.  DPP series Blister Machine driving system   

DPP series Blister Machine working principle: Blister Machine forming material normally is PVC film 1 and lidding foil normally is Alu foil 8 are dragged into each work position intermittently by roller traction mechanism12. Firstly, Forming material (PVC) 1 go through forming turn stick 2 come into forming heat plate 3 . Then the material which has been come into the forming station 4. is extended  and formed blister by the compressed air 5. When the blister come into feeding device 6, it will be filled with medicines. Then it will come into heat sealing position 9. Alu foil 8 through the alu turn stick 7 enter the heat sealing position 9. Here PVC and ALU are bonded and the medicines are sealed in the blister. Then enter into the embossing position 10 to emboss production batch number. And enter the perforation working station 11 to perforate the peel line.  Finally it enteres the cutter working station 13 and is cut into blister card. The rest material will be collected by waste winding mechanism 15 through  the waste winding turn stick 14. In this series Blister Packaging Machine every working position worked in synchronized way.  DPP series Blister Machine schematic diagram:   1. Blister Machine forming material(PVC) 2.
