The blister film roll is unwound by the receiving mechanism 3, and then conveyed to the preheating mechanism 5 by the feeding mechanism 4. In the process, when the current material roll is used up and a new material roll is unwound, the material can be connected at the docking mechanism 41, the blister film is heated by the preheating mechanism 5, the heated blister film is formed into a blister by the forming mechanism 6, and is transported by the first traction mechanism 7. The first traction mechanism 7 transports the formed blister through the material area, and generally a device for adding materials is provided in the material area. The device for adding materials fills the materials into the blister, and then transports it to the heat sealing mechanism 9. The heat sealing mechanism 9 heat-seals the heat-sealing film on the blister filled with the material to form a seal. The heat-sealed blister is transported to the cutting mechanism 11 by the second traction mechanism 10 for cutting, so as to cut the continuous blister into a size that can be commercialized and circulated. The cut blister is transported to the next process by the conveying mechanism 12 for sorting and packaging, and the waste left by the cutting is processed by the waste processing mechanism 13.

In this way, when the automatic blister packaging machine stops, the preheating mechanism 5 can drive the vertical plate 501 to slide along the guide column 201 through the first driving mechanism 504 to drive the preheating mechanism 5 as a whole away from the forming mechanism 6, and then the upper bracket 510 and the lower bracket 511 are driven by the second driving mechanism 505 and the third driving mechanism 506 to slide up and down along the linear track 507 respectively, so that the upper heating plate 502 and the lower heating plate 503 are separated from each other and opened, thereby preventing the blister film between the upper heating plate 502 and the lower heating plate 503 from being damaged due to continuous heating. It has a simple structure, convenient operation, and easy control.

[0033] Through the above arrangement, the distances between the forming mechanism 6, the heat sealing mechanism 9 and the cutting mechanism 11 can be conveniently adjusted to adapt to different blister sizes, with high positioning accuracy and convenient adjustment.

[0034] Furthermore, two guide columns 201 are provided on the wall panel 2 at intervals in the upper and lower parts, and the upper and lower ends of the vertical plate 501 are respectively connected to the corresponding guide blocks 202 on the two guide columns 201, and the two ends of each guide column 201 are respectively connected to the wall panel 2 through the fixing seat 512 to realize the connection and fixation between the guide column 201 and the wall panel 2, with good stability.

The forming mechanism 6, the heat-sealing mechanism 9 and the cutting mechanism 11 are all connected to the adjusting mechanism. The adjusting mechanism can adjust the positions of the forming mechanism 6, the heat-sealing mechanism 9 and the cutting mechanism 11 on the wall panel 2 along the advancing direction of the blister to match and adapt to different blister packaging requirements and enhance adaptability. In this embodiment, the structures and principles of the adjusting mechanisms of the forming mechanism 6, the heat-sealing mechanism 9 and the cutting mechanism 11 are the same. Specifically, the forming mechanism 6, the heat sealing mechanism 9 and the cutting mechanism 11 all include a mold frame 601, and sliding blocks 602 are respectively provided at the upper and lower ends of the mold frame 601. A guide rail 603 is provided on the wall panel 2 corresponding to the sliding block 602, and the sliding block 602 is slidably arranged in the guide rail 603. The adjustment mechanism includes an adjustment seat 604, a screw nut assembly and a fourth driving mechanism 607 for driving the screw nut assembly.

The connecting block 608 is connected to the nut 606 of the screw nut assembly. When it is necessary to adjust the forming mechanism 6, the heat sealing mechanism 9 or the cutting mechanism 11, the screw 605 is directly driven to rotate through the fourth driving mechanism 607, driving the nut 606 to move along the screw 605, thereby driving the mold frame 601 corresponding to the forming mechanism 6, the heat sealing mechanism 9 or the cutting mechanism 11 to slide along the guide rail 603 to change its position on the wall panel 2.

[0036] Furthermore, the fourth driving mechanism 607 is arranged on one side of the adjustment seat 604, and the fourth driving mechanism 607 includes a servo motor 6071, a driving wheel 6072, a driven wheel 6073, and a conveyor belt connecting the driving wheel 6072 and the driven wheel 6073. The driving wheel 6072 is connected to the output end of the servo motor 6071, and the driven wheel 6073 is connected to the screw rod 605 of the screw rod 605 nut assembly. The servo motor 6071 drives the driving wheel 6072 to rotate, driving the driven wheel 6073 to rotate, and then drives The movable screw 605 rotates to drive the mold frame 601 connected to the nut of the screw 605 nut assembly to move. Here, the axis of the screw 605 is parallel to the guide rail 603. A servo motor 6071 is used as a driving power source, which can be conveniently connected to the electronic control system (not shown) of the automatic blister packaging machine. The positions of the forming mechanism 6, the heat sealing mechanism 9 and the cutting mechanism 11 in the direction of blister travel can be quickly and accurately adjusted and positioned through the touch screen of the electronic control system, which has the advantages of convenient adjustment and setting and accurate positioning.

[0037] In this embodiment, the automatic blister packaging machine also includes a compensation and correction mechanism 14, which is arranged between the second traction mechanism 10 and the cutting mechanism 11.

The two ends of the correction groove 1401 are respectively connected with the second traction mechanism 10 and the cutting mechanism 11. A photoelectric sensor 1402 is provided at the end of the correction groove 1401. The compensation and correction mechanism 14 is provided to compensate and correct the blisters conveyed by the second traction mechanism 10, so as to ensure the accuracy of cutting by the cutting mechanism 11, and further ensure the quality of blister cutting. Specifically, the blisters move along the correction groove 1401 to prevent the blisters from being skewed and offset. The photoelectric sensor 1402 detects the forward position of the blisters and sends the real-time position signal to the electronic control system, thereby controlling the traction speed of the second traction mechanism 10, so as to accurately send the blisters into the cutting mechanism 11, realize correction and feeding compensation, and ensure the quality of blister cutting.

[0038] In this embodiment, the automatic blister packaging machine further includes a cooling mechanism 15, which is disposed at the outlet of the heat sealing mechanism 9.

The cooling plate 153 is located above the guide plate 152, and both sides of the cooling plate 153 are correspondingly slidably disposed in the first slide rail 156 and the second slide rail 157, respectively. The fifth driving mechanism 154 is connected to the cooling plate 153 and is used to drive the cooling plate 153 to move along the first slide rail 156 and the second slide rail 157. 7 slides to extend into the heat sealing mechanism 9 or retract. When the automatic blister packaging machine works normally, the cooling plate 153 is located above the guide plate 152. After the blisters are heat-sealed by the heat sealing mechanism 9, they enter the next process through the guide groove 155 on the guide plate 152. When the automatic blister packaging machine stops, the upper and lower molds of the heat sealing mechanism 9 need to be opened. At this time, the fifth driving mechanism 154 starts and drives the cooling plate 153 to slide along the first slide rail 156 and the second slide rail 157 to extend between the upper and lower molds of the heat sealing mechanism 9. The cooling plate 153 extends into the heat sealing mechanism 9 to block the heat transfer of the upper mold to the blisters above the upper mold, thereby preventing the blisters staying in the heat sealing area from affecting the performance of the packaged items due to long-term continuous heating. The structure is simple, the operation is convenient, and the blisters packaged with materials are effectively protected.
