[0031] Working principle:

[0032] When blister packaging work is to be carried out on the required items, when the items on the conveyor belt 7 move to the block 6 of the box body 1, the conveyor belt 7 is turned off. Then the worker removes the block 6 from the box body 1. After the block 6 is removed, the external power supply of the first motor 202 is connected and started. The first motor 202 drives the worm 203 to rotate. The worm 203 drives the worm wheel 204 to rotate (the worm 203 and the worm wheel 204 have a self-locking function. When the roller 205 does not drive the cross plate 206 to move, the cross plate 206 is not easily affected by the outside world and moves). The worm wheel 204 drives the roller 205 to rotate. The roller 205 drives the cross plate 206 to move to the right through the arc-shaped groove. The outer wall of the cross plate 206 contacts the item and then pushes it onto the protruding part of the box body 1 (such as Figure 8 ), and then it is pushed into the box body 1 and pushed onto the workbench 5. After the item is pushed onto the workbench 5, the first motor 202 continues to rotate in the above manner, so that the roller 205 can drive the cross plate 206 to move in the reverse direction through the arc-shaped groove. (The arc-shaped groove on the front side of the roller 205 is connected to the arc-shaped groove on the rear side, so it can drive the cross plate 206 to move in the reverse direction, such as Figure 7 ). After the cross plate 206 is reset, the first motor 202 is turned off. The item is pushed above the workbench in the above manner for subsequent blister packaging work;

[0033] Then the block 6 is reset onto the box body 1 (the block 6 is fitted to the box body 1 through a sealing ring, and the sealing ring can prevent air leakage at the connection between the box body 1 and the block 6). Then the worker pulls the packaging wound around the cylinder 16, so that the packaging bag passes through the lower side of the blade 307 and the notch on the right side of the frame 8 in sequence. Then the worker continues to pull the packaging bag. The worker measures the length of the packaging bag according to the scale line. When the length of the packaging bag reaches the required length, the pulling of the packaging bag is stopped;

[0034] Subsequently, the external power supply of the second motor 302 is connected and started. The second motor 302 drives the disc 303 to rotate (the disc 303 rotates eccentrically, such as Figure 5), the disk 303 drives the finger board 304 to move downward. At this time, the spring 306 is compressed to form an elastic force. The support board 304 drives the blade 307 to move downward. The lower end of the blade 307 contacts the packaging bag and then cuts and severs it. After the packaging bag is severed, reverse the rotation of the second motor 302 according to the above method. The spring 306 rebounds to release the elastic force and drives the blade 307 to reset. After the blade 307 is reset, turn off the second motor 302. Then connect the external power supply of the two second electric telescopic rods 11 and start them. The output ends of the two second electric telescopic rods 11 extend simultaneously to drive the first plate body 12 to move downward. After the lower end of the first plate body 12 abuts against the second plate body 13, turn off the two second electric telescopic rods 11. In this way, the packaging to be pressed is clamped between the first plate body 12 and the second plate body 13 (since rubber rings are provided on the outer wall of the lower end of the first plate body 12 and the upper outer wall of the second plate body 13, the space between the first plate body 12 and the second plate body 13 is sealed);

[0035] Then connect the external power supply of the air cylinder 9 and start it. The air cylinder 9 drives the heating plate 10 to move downward. After the heating plate 10 moves to the position required for work, turn off the air cylinder 9 to stop the heating plate 10 from moving downward. Subsequently, connect the external power supply of the heating plate 10 and start it. The heating plate 10 generates heat and transfers the heat to the packaging bag to soften it. After the packaging bag is softened, turn off the heating plate 10. Start the air cylinder 9 to retract its contraction end to drive the heating plate 10 to move upward to reset. After the heating plate 10 is reset, turn off the air cylinder 9. Then connect the air inlet on the left side of the second plate body 13 to an external blowing device, and make its air inlet blow air towards the heat-softened packaging bag to blow the packaging bag to bulge. Then connect the external power supply of the first electric telescopic rod 4 and start it. The output end of the first electric telescopic rod 4 extends to drive the workbench 5 to move upward, thereby driving the items on the workbench 5 to move upward. After the items contact the bulged packaging bag, turn off the first electric telescopic rod 4 and stop the air inlet on the left side of the second plate body 13 from blowing air into the packaging bag. Then connect the air suction port on the right side of the second plate body 13 to an external vacuum pump, and make it suck air from the packaging bag to remove the gas between the packaging bag and the items. As the gas is sucked out, the packaging bag will adsorb on the items, thus realizing the automatic blister packaging work for the items;

[0036] After the blister packaging of the items is completed, stop the air suction of the air suction port on the right side of the second plate body 13. Then start the two second electric telescopic rods 11 to retract their output ends to drive the first plate body 12 to move upward to reset. After the first plate body 12 is reset, turn off the two first electric telescopic rods 11. Subsequently, the worker uses an external blade to cut the packaging bag with excess edges. After the packaging to be cut is completed, the worker can manually remove it. In this way, the automatic blister packaging work for the packaging to be is completed (the worker can clean the cut packaging bag by himself).

[0037] When the packaging bag is used up and needs to be replaced, turn the disc 17 to separate it from the rotating shaft of the cylinder body 16. Then the worker can pull out the cylinder body 16 from the column body 15, and the cylinder body 16 can be disassembled. By the above method, the limit on the cylinder body 16 is cancelled. Then insert the cylinder body 16 with a new packaging bag wound around it into the column body 15. Finally, limit the new cylinder body 16 according to the above method, and the replacement of the packaging bag can be completed by the above method.

[0038] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details may be made within the scope of the claims.
