Without further description, the left side surface of the placement box 3 is fixedly connected to the first motor 8, the output shaft of the first motor 8 rotates and passes through the interior of the placement box 3 and is fixedly connected to the reciprocating screw rod 7, the lower surface of the placement plate 5 is provided with a transverse groove 10, the interior of the transverse groove 10 is slidably connected to a connecting block 11, the connecting block 11 and the reciprocating screw rod sleeve 9 are fixedly connected, the interior of the transverse groove 10 is fixedly connected to a first guide rod 12, the connecting block 11 is slidably sleeved on the outer surface of the first guide rod 12, and the two side surfaces of the connecting block 11 and the two side inner walls of the transverse groove 10 are fixedly connected with a first spring 13, the two first springs 13 are both sleeved on the outside of the first guide rod 12, the two side inner walls of the groove 4 are provided with a limiting groove 14, the two side surfaces of the placement plate 5 They are all fixedly connected to the limit rod 15, and the limit rod 15 is slidably connected to the inside of the limit groove 14. A pressing component is provided on the surface of the placement plate 5. When the staff needs to stack the plastic packaging bags, the plastic packaging bags are first conveyed to one side of the placement box 3 through the conveyor platform 1. The subsequent plastic packaging bags will pass through the guide plate 2 and fall to the upper side of the left placement plate 5. Then, by starting the first motor 8, the rotation of the output shaft of the first motor 8 will drive the rotation of the reciprocating screw rod 7. The rotation of the reciprocating screw rod 7 will drive the reciprocating screw rod sleeve 9 to slide to the left inside the guide groove 6. The movement of the reciprocating screw rod sleeve 9 will drive the movement of the connecting block 11. At this time, under the restriction of the two first springs 13, the connecting block 11 will drive the two placement plates When the reciprocating screw rod sleeve 9 moves to the left, the limiting rod 15 will slide inside the limiting groove 14. After the limiting rod 15 contacts the left inner wall of the limiting groove 14, the placing plate 5 will no longer move. The reciprocating screw rod sleeve 9 will continue to drive the connecting block 11 to move to the left, and then the connecting block 11 will slide on the surface of the first guide rod 12. At this time, the left first spring 13 will contract and the right first spring 13 will stretch. Subsequently, the left placing plate 5 will stay on the lower side of the guide plate 2. At this time, the plastic packaging bag can be received by the left placing plate 5. When the reciprocating screw rod sleeve 9 moves to the leftmost end, it will move to the right. At this time, the reciprocating screw rod sleeve 9 will drive the connecting block 11 to slide to the right inside the transverse groove 10, and then the two first springs 13 will gradually reset.After the two first springs 13 return to their original state, the reciprocating screw sleeve 9 and the connecting block 11 will drive the placement plate 5 to move to the right until the limiting rod 15 contacts the right inner wall of the limiting groove 14. At this time, the first spring 13 on the right side contracts, and the right placement plate 5 will stay on the lower side of the guide plate 2, finally realizing the right placement plate 5 to receive the plastic packaging bag. The above structure greatly increases the load capacity of the plastic packaging bag, thereby improving it. When the plastic packaging bag on one side needs to be unloaded, the other side can still carry out the plastic packaging bag receiving work, thereby ensuring the continuity of the plastic packaging bag unloading, thereby improving the work efficiency of the staff, and having high practicality and simple operation.

[0027] In the above embodiment, the first spring 13 is a shock-absorbing spring. When the external force disappears, the first spring 13 will return to its original shape, thereby preventing the placement plate 5 from shaking.

[0028] The two L-shaped fixing plates 21 are fixedly connected to the two sides of the placing plate 5 respectively, and the surfaces of the opposite sides of the vertical plates of the two L-shaped fixing plates 21 are provided with vertical grooves 17. The interiors of the two vertical grooves 17 are fixedly connected to second guide rods 19, and a pressure plate 18 is provided between the two L-shaped fixing plates 21. The two ends of the pressure plate 18 are respectively slidably connected to the interiors of the two vertical grooves 17 and slidably sleeved on the outside of the second guide rod 19. A second spring 20 is fixedly connected between the L-shaped fixing plates 21 and the bottom wall of the vertical groove 17. The second spring 20 is sleeved on the outside of the second guide rod 19. The interiors of the two L-shaped fixing plates 21 are provided with cavities 22, and the interiors of the cavities 22 are provided with a driving assembly. When the plastic packaging bag needs to be compressed, the driving assembly drives the pressure plate 18 to slide downward. At this time, the two sides of the pressure plate 18 will slide inside the vertical grooves 17, and the second spring 20 will deform, ultimately achieving synchronous compression of the plastic packaging bags on both sides.

[0029] Furthermore, a baffle 16 is fixedly connected to the upper surface of the placement plate 5 .

[0030] Furthermore, the driving assembly includes a winding roller 23, which is rotatably connected to the inside of the left cavity 22, and the right end of the winding roller 23 rotates to penetrate the inside of the placement plate 5 and extends into the inside of the right cavity 22. The surface of the left L-shaped fixed plate 21 is fixedly connected to the second motor 26, and the output shaft of the second motor 26 rotates to penetrate the inside of the L-shaped fixed plate 21 and is fixedly connected to the winding roller 23. One end of the winding roller 23 located inside the cavity 22 is provided with a partition plate 24, and a pull rope 25 is provided between the two partition plates 24. The pull rope 25 is wound around the outside of the winding roller 23, and the other end of the pull rope 25 slides into the inside of the vertical slot 17 and is fixedly connected to the pressure plate 18. When the plastic packaging bag needs to be compressed, , by starting the second motor 26, the rotation of the output shaft of the second motor 26 can drive the rotation of the winding roller 23, thereby realizing the winding of the drawstring 25. At this time, the pressure plate 18 can be moved downward by winding the drawstring 25, and finally the plastic packaging bag is compressed. Subsequently, the output shaft of the second motor 26 is reversed. At this time, the winding roller 23 will pay out the drawstring 25, and the pressure plate 18 can be reset by relying on the elastic force of the second spring 20 itself. Through the cooperation of the driving component and the compression component, the plastic packaging bags can be avoided as much as possible from becoming fluffy after being stacked, and the two sides can be compressed synchronously, which reduces the working steps and improves the compression efficiency of the plastic packaging bags. It is highly practical and easy to operate.

[0031] Working principle:

[0032] When the stacking mechanism for plastic packaging bag production is in use, when the staff needs to stack the plastic packaging bags, the plastic packaging bags are first transported to one side of the placement box 3 through the conveyor table 1, and the subsequent plastic packaging bags will pass through the guide plate 2 and fall to the upper side of the left placement plate 5, and then by starting the first motor 8, the rotation of the output shaft of the first motor 8 will drive the rotation of the reciprocating screw 7, and the rotation of the reciprocating screw 7 will drive the reciprocating screw sleeve 9 to slide to the left inside the guide groove 6, and the movement of the reciprocating screw sleeve 9 will drive the movement of the connecting block 11. At this time, under the restriction of the two first springs 13, the connecting block 11 will drive the two placement plates 5 to move to the left, and the limiting rod 15 will slide inside the limiting groove 14. After the limiting rod 15 contacts the left inner wall of the limiting groove 14, the placement plate 5 will no longer move, and the subsequent reciprocating screw sleeve When the first springs 13 return to their original positions, the reciprocating screw sleeve 9 and the connecting block 11 will drive the placing plate 5 to move to the right until the limiting rod 15 contacts the right inner wall of the limiting groove 14, and the first spring 13 on the right side contracts. At this time, the right placing plate 5 will stay on the lower side of the guide plate 2, and finally the right placing plate 5 will receive the plastic packaging bag.
