[0028] Two composite templates 10 are set on the support frame 2. The two composite templates 10 are arranged symmetrically, and heat sealing components are provided on the opposite surfaces of the two composite templates 10. A motor 36 is fixed on the support frame 22.

[0029] A film feeding mechanism is provided on the stand 2, which is used to feed packaging film between the two templates 10;

[0030] The conveying mechanism installed on the upright 2 and the support 22 uses a motor 36 to drive the two joining templates 10 to join together while using a heat sealing assembly to seal the paper-plastic cup. As the motor 36 drives the two joining templates 10 to move away from each other, it drives a film feeding mechanism to convey the packaging film between the two joining templates 10. The motor 36 also drives the conveying mechanism to transport the paper-plastic cup to be packaged between the two joining templates 10 and simultaneously outputs the sealed paper-plastic cup.

[0031] In this embodiment, each of the two mold plates 10 has a sliding rod 3 with a polygonal cross-section fixed on its opposite side. The sliding rod 3 passes through and is slidably connected to the upright frame 2. Each of the two mold plates 10 has a groove 24 on its opposite side. Each of the two mold plates 10 has a cutter 28 fixed at its upper end. When the two cutters 28 are aligned, they are used to cut the packaging film.

[0032] In this embodiment, the heat sealing assembly includes a heat sealing frame 29 and a heat sealing strip 27. A cutter 28 is located between the heat sealing strip 27 and the heat sealing frame 29. The heat sealing frame 29 and the heat sealing strip 27 are both vertically and fixedly connected to a top rod 30 on the side facing the corresponding assembly template 10. The top rod 30 on the heat sealing strip 27 passes through and is slidably connected to a protrusion 26, and the protrusion 26 is fixed to the upper end of the corresponding assembly template 10. A limit block 32 is fixed to the end of the top rod 30 away from the heat sealing strip 27, and the limit block 32 is connected to the protrusion 26 through a spring 31. The top rod 30 on the heat sealing frame 29 passes through and is slidably connected to the corresponding assembly template 10. A limit block 32 is fixed to the end of the top rod 30 away from the heat sealing frame 29, and the limit block 32 is connected to the corresponding assembly template 10 through a spring 31.

[0033] In this embodiment, the film feeding mechanism includes two support platforms 5, both of which are fixed on the frame 2 and are symmetrically arranged. The two support platforms 5 are also arranged in a one-to-one correspondence with the two assembly templates 10. A film feeding roller group 6 is rotatably connected to the support platform 5, and the film feeding roller group 6 is drivenly connected to the inner ring of the ratchet 7. A support rod 25 is fixedly connected to the protrusion 26 corresponding to the support platform 5. A rack 8 is fixed to the upper end of the support rod 25, and the rack 8 is parallel to the slide rod 3. The rack 8 is meshed with the outer ring of the corresponding ratchet 7. A guide film wheel 9 and a sealing film roll 4 are rotatably connected to the support platform 5. The end of the packaging film on the sealing film roll 4 passes through the film feeding roller group 6 and around the guide film wheel 9 and is located between the two assembly templates 10.

[0034] In this embodiment, the output shaft of the motor 36 is connected to the turntable 19. One end of the connecting rod 18 is hinged to the turntable 19 at a position away from the center. The other end of the connecting rod 18 is hinged to one end of the rack 17. The rack 17 is inserted into and slidably connected in the sliding sleeve 16, and the sliding sleeve 16 is fixed on the stand 2. The stand 2 is rotatably connected to the gear 13.

[0035] In this embodiment, the conveying mechanism includes a first conveyor frame 11 fixed on the upright frame 2 and a second conveyor frame 20 fixed on the support 22. Both ends of the first conveyor frame 11 and the second conveyor frame 20 are rotatably connected to rollers 34. The rollers 34 at both ends of the same conveyor frame are connected by a conveyor belt 33. The outer surface of the conveyor belt 33 is fixed with multiple protrusions 35 at equal intervals along the length of the conveyor belt 33. The length direction of the protrusions 35 is perpendicular to the running direction of the conveyor belt. The turntable 19 is connected to the rollers 34 at one end of the first conveyor frame 11 and the second conveyor frame 20 by a pulley group 1 23 and a pulley group 21, respectively.

[0036] Working principle and advantages of this invention: The working process of this paper-plastic cup packaging device when packaging paper-plastic cups is as follows:

[0037] like Figure 1 and Figure 2As shown, the motor 36 drives the turntable 19 to rotate clockwise. The rotation of the turntable 19 alternately applies tension and thrust to the rack 17 via the connecting rod 18, causing the rack 17 to complete one right-left movement during one rotation of the turntable 19. As the turntable 19 rotates continuously, it performs a reciprocating right-left-right movement. During the leftward movement of the rack 17, it drives the gear 13 to rotate clockwise, which in turn drives the gear 14 to rotate clockwise. This causes the gear 14 to move closer to the two mold plates 10 via the racks 12 and 15. During this movement, the two heat-sealing frames 29 and two heat-sealing strips 27 move closer together. When the two heat-sealing strips 27 are bonded together, the two packaging films are heat-sealed. Similarly, when the two heat-sealing strips 27 are bonded together, the two packaging films are heat-sealed. The two heat-sealing strips 27 and the two heat-sealing frames 29 are subjected to mutual forces, and the spring 31 is pulled by the corresponding top rod 30 and the limiting block 32, so that the spring 31 obtains a restoring force. When the closing template 10 is in contact with the corresponding heat-sealing frame 29 and the protrusion 26 is in contact with the corresponding heat-sealing strip 27, the two cutters 28 are joined together and cut the packaging film. At this time, the two heat-sealing frames 29 complete the sealing of the paper-plastic cup. The two heat-sealing strips 27 heat-seal the lower ends of the two cut packaging films so that the paper-plastic cup to be sealed can be caught when it falls between the two closing templates 10 on the conveyor frame 20.

[0038] As described above, during the process of the two mold plates 10 approaching each other, the protrusion 26 and the support rod 25 synchronously drive the two racks 8 to approach each other. At this time, the rack 8 drives the outer ring of the corresponding ratchet 7 to rotate, and the outer ring of the ratchet 7 cannot drive the inner ring to rotate through the pawl. Thus, during this process, the inner ring of the ratchet 7 cannot drive the film feeding roller group 6 to transport the packaging film. This ensures that the packaged paper-plastic cup is at the height position corresponding to the groove 24 on the two mold plates 10, ensuring the accuracy of the packaging.

[0039] While the two cutters 28 are cutting the packaging film together, the turntable 19 drives the rack 17 to move to the right via the connecting rod 18. During the movement of the rack 17 to the right, the rack 17 drives the gear 13 to rotate counterclockwise, which in turn drives the gear 14 to rotate counterclockwise. This causes the gear 14 to drive the two mold plates 10 to move away from each other via the rack 12 and the rack 15. During the movement of the two mold plates 10 away from each other, the two heat sealing frames 29 and the two heat sealing strips 27 move away from each other. Under the restoring force of the spring 31, the corresponding heat sealing strips 27 and heat sealing frames 29 are reset.

[0040] As described above, during the process of the two mold plates 10 moving away from each other, the protrusion 26 and the support rod 25 synchronously drive the two racks 8 to move away from each other. At this time, the rack 8 drives the outer ring of the corresponding ratchet 7 to rotate in the opposite direction, and the outer ring of the ratchet 7 can drive the inner ring to rotate through the pawl. Thus, during this process, the inner ring of the ratchet 7 can drive the film feeding roller group 6 to transport the packaging film, realize the automatic transport of the packaging film, save time and effort, so as to seal the lowered paper-plastic cup.

[0041] During the clockwise rotation of turntable 19, turntable 19 drives the rollers 34 on conveyor frame 20 and conveyor frame 11 to rotate via pulley group 21 and pulley group 23. This causes the rollers 34 to drive the corresponding conveyor belt 33 clockwise. The conveyor belt 33 on conveyor frame 20 moves the paper-plastic cups to be packaged above the two mold plates 10. As the two mold plates 10 move away from each other, a paper-plastic cup falls between them. As the mold plates move closer together, no paper-plastic cup falls between them. This ensures that only one paper-plastic cup can be packaged at a time. The packaged paper-plastic cup falls onto the conveyor belt 33 on conveyor frame 11 and is output via the conveyor belt 33. Figure 4 As shown, the protrusions 35 on the conveyor belt 33 act as a barrier for the paper-plastic cups.

[0042] When the two mold plates 10 are at their furthest apart, the turntable 19 drives the rack 17 to move to the left again via the connecting rod 18. This causes the rack 17 to drive the gear 13 to rotate clockwise, which in turn drives the gear 14 to rotate clockwise. This causes the gear 14 to drive the two mold plates 10 to move closer together via the rack 12 and rack 15. This allows the two mold plates 10 to drive the two heat-sealing frames 29 and the two heat-sealing strips 27 to heat-seal the packaging film. The entire device automatically transports the paper-plastic cups to be packaged, automatically heat-seals the paper-plastic cups, and automatically transports the packaging film. At the same time, it outputs the sealed paper-plastic cups, greatly improving the degree of automation, eliminating the need for manual intervention, reducing labor intensity and error rate, and improving production efficiency.
