When in use, the transmission chain at the top is driven to move to the right by the transmission roller, so that the plastic plate at the top of the transmission chain flows through the blister cutting section. After the workpiece is blister-formed and cut by the blister cutting section, the waste material continues to move to the inside of the recovery bin with the movement of the transmission chain, and is recovered by the residual material recovery mechanism. During the recycling process, the recovered materials are quantitatively divided by the synchronous dividing mechanism, and finally the waste material is crushed by the multi-stage crushing mechanism for subsequent processing.

When the driving motor is started, the driving shaft starts to rotate, driving the driving roller to start rotating, and when the driving roller rotates, it drives the transmission chain meshed with it to start moving, so that the plastic plate waste at the top of the transmission chain enters the feed port.

[0007] Furthermore, a stacking rack is provided in the middle of the recycling bin, the stacking rack is fixedly connected to the inner wall of the recycling bin, the stacking rack is provided in a rectangular parallelepiped, a stacking trough is provided inside the stacking rack, and the length and width of the stacking trough match the length and width of the plastic board.

When the third wheel disc rotates, the fourth wheel disc is driven to rotate through the second transmission belt meshed with it, so that the first feeding roller between the connecting seats starts to rotate. When the first feeding roller rotates, the friction between it and the plastic sheet drives the plastic sheet to continue to move to the right. At this time, the second feeding roller on the top of the plastic sheet is pushed upward by the upward thrust, so that the telescopic rod is extended, driving the movable seat to move upward. When the movable seat moves upward, it drives the top guide rod to move upward, so that the second spring is compressed, generating a downward elastic force, so that the plastic sheet is closely fitted with the first feeding roller and the second feeding roller during the movement, avoiding multiple plastic sheets from flowing out at a time.

The waste can be collected centrally through the stacking trough, and the guide plate can prevent the waste from being scattered inside the stacking trough, thereby improving the space utilization rate.

[0016] When the second feeding roller rotates, the friction force between the first feeding roller and the plastic sheet drives the plastic sheet to move continuously to the right. At this time, the second feeding roller at the top of the plastic sheet is pushed upward by the upward thrust, so that the telescopic rod is extended, driving the movable seat to move upward. When the movable seat moves upward, it drives the top guide rod to move upward, so that the second spring is compressed and generates a downward elastic force, so that the plastic sheet is closely fitted with the first feeding roller and the second feeding roller during the movement, so as to avoid multiple plastic sheets flowing out at a time.

[0031] Working principle: Start the driving motor, so that the driving shaft starts to rotate, driving the driving roller 13 to start rotating. When the driving roller 13 rotates, it drives the transmission chain 2 meshing therewith to start moving, so that the plastic plate 4 waste on the top of the transmission chain 2 enters the feed port 12. After the plastic plate 4 waste enters the feed port 12, it flows into the inside of the stacking rack 16 along the guide plate 17, and then is stacked at the bottom of the stacking trough 24. The waste can be collected centrally through the stacking trough 24, and the guide plate 17 can prevent the waste from being scattered inside the stacking trough 24, thereby improving the space utilization rate.

[0032] When the driving shaft rotates, it drives the first wheel plate 14 to rotate accordingly. When the first wheel plate 14 rotates, the second wheel plate 22 starts to rotate through the first transmission belt 15 meshing therewith, so that the transmission shaft 39 starts to rotate. When the transmission shaft 39 rotates, it drives the remaining wheel plate 45 and the third wheel plate 21 to start rotating. When the remaining wheel plate 45 rotates, it drives the roller 44 abutting therewith to start rotating. When the remaining wheel plate 45 rotates until the roller 44 contacts the arc opening 46, at this time, the rocker 41 rotates to the right under the pulling force of the first spring 43, driving the slider 37 at the top of the rocker 41 to slide right along the slide groove 36, so that the push block 38 at the top of the slider 37 pushes the bottom plastic plate 4 to move to the right. When the plastic plate 4 moves to the right, it passes through the discharge port and moves to between the first feeding roller 29 and the second feeding roller 28. When the third wheel plate 21 rotates, it drives the fourth wheel plate 31 to start rotating through the second transmission belt 33 meshing therewith, so that the first feeding roller 29 between the connecting seats is connected to the fourth wheel plate 31. The roller 29 starts to rotate. When the first feeding roller 29 rotates, the friction between the first feeding roller 29 and the plastic plate 4 drives the plastic plate 4 to move continuously to the right. At this time, the second feeding roller 28 on the top of the plastic plate 4 is pushed upward, so that the telescopic rod 32 is extended, driving the movable seat 27 to move upward. When the movable seat 27 moves upward, it drives the top guide rod 34 to move upward, so that the second spring 35 is compressed, generating a downward elastic force, so that the plastic plate 4 is closely fitted with the first feeding roller 29 and the second feeding roller 28 during the movement, avoiding the plastic plate 4 from flowing out multiple sheets at a time. With the continuous rotation of the residual wheel 45, the rocker 41 reciprocates under the pulling force of the first spring 43, thereby continuously pushing out the plastic plate 4, and finally flowing out evenly along the discharge chute 18 through the discharge plate 40, thereby realizing the quantitative and synchronous distribution of the waste plastic plate 4, avoiding the subsequent multi-stage crushing mechanism from being blocked due to excessive single outflow of the plastic plate 4.

[0033] When the fourth wheel disc 31 rotates, the fifth wheel disc 47 is driven to start rotating through the third transmission belt 48 meshing therewith. When the fifth wheel disc 47 rotates, it drives the driving gear 50 to start rotating. At this time, the plastic plate 4 waste flows into the first crushing section along the upper opening. When the driving gear 50 rotates, it drives the driven gear 49 meshing therewith to rotate toward each other, so that the pair of crushing rollers 54 inside the first crushing section rotate toward each other, and the plastic plate 4 waste is preliminarily crushed. When the driven gear 49 rotates, it drives the driving bevel gear 51 to start rotating, so that the driven bevel gear 52 meshing therewith starts to rotate. When the driven bevel gear 52 rotates, it drives the first gear 55 to start rotating through the connecting shaft 53. When the first gear 55 rotates, it drives the second gear 56 meshing therewith to start rotating, so that the central shaft starts to rotate. When the central shaft rotates, it drives the blades 57 on its side wall to start rotating, and the plastic plate 4 waste that has been preliminarily crushed is further crushed. The waste that has been crushed in multiple stages is discharged along the discharge port 58. Through the above steps, multi-stage crushing of the plastic plate 4 waste can be achieved, which is convenient for subsequent treatment of the waste.

[0034] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
