Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, and in particular to a plastic sheet waste recycling device. Background Technology

[0002] An existing device (CN 216884080 U) for recycling waste trimmings from PVC sheets uses a trimming blade to cut waste from both sides of the plastic sheet. When the waste trimmings move above the rightmost conveyor roller, a lifting cylinder is activated, causing a waste guide plate to move downwards, pressing the ends of the waste trimmings downwards. This further guides and conveys the waste trimmings, preventing them from lifting and smoothly transporting them into the recycling chamber for crushing, facilitating later storage and transportation. However, this device only crushes the waste using relatively rotating crushing rollers, which may cause over-crushing of the plastic sheet, resulting in a powdery residue and affecting its future reuse.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, a plastic sheet waste recycling device includes a support mechanism, which includes a box 11. The upper end of the box 11 is connected to a feeding hopper 12. A guide plate 15 is provided on the inner wall of the box 11 below the feeding hopper 12. A bracket 13 is fixedly provided at the lower end of the box 11. A discharge port 14 is provided at the bottom of the box 11. The device also includes a crushing mechanism provided inside the box 11 for crushing the added plastic sheets.

[0027] In this embodiment: the crushing mechanism includes a ring cutting component for cutting plastic sheets into strips, and a shearing component for cutting the plastic sheets after stripping is provided on the lower side of the ring cutting component. The ring cutting component is connected to the shearing component, and a power component is connected to the ring cutting component.

[0028] The ring-cutting assembly includes two rotating shafts 21 horizontally arranged on the housing 11. Ring blades 22 are fixed at intervals on the rotating shafts 21, with the ring blades 22 facing each other. One end of the rotating shaft 21 passes through the housing 11 and is fitted with a meshing first gear 23. The shearing assembly includes two shearing seats 28 located below the ring blades 22. Shearing blades 29 facing each other are fixed on the shearing seats 28. Reciprocating moving components are connected to both sides of the shearing seats 28. A through groove 101 is provided on the side wall of the housing 11 through which the shearing seats 28 pass. The rotating shafts 21 are rotatably connected to the housing 11. Power is transmitted through the rotation of the rotating shafts 21 and the meshing of the first gears 23, causing the rotating shafts 21 and the ring blades 22 to rotate relative to each other. The plastic waste sheet is cut into strips downwards by the ring blades 22.

[0029] The reciprocating moving assembly includes a turntable 24 fixed at both ends of a rotating shaft 21. A drive rod 25 is connected to the outside of the turntable 24 via a pin. A connecting rod 27 rotatably connected to the shearing seat 28 is provided at the lower end of the drive rod 25. A support seat 26 rotatably connected to the drive rod 25 is installed on the outer wall of the housing 11. A sliding groove is provided on the drive rod 25. The drive rod 25 and the connecting rod 27 are rotatably connected via a pin. The shearing seat 28 is slidably connected to the through groove 101. When the turntable 24 rotates with the rotating shaft 21, the turntable 24 drives the drive rod 25 to move back and forth relative to the shearing seat 28 under the support of the support seat 26, so that the shearing blade 29 on the shearing seat 28 cuts the plastic strip after it has been cut.

[0030] The power assembly includes a secondary pulley 210 mounted on the shaft 21 away from the first gear 23, a motor 211 fixedly mounted on the outer wall of the housing 11, a main pulley 212 mounted on the output shaft of the motor 211, and belts fitted on the main pulley 212 and the secondary pulley 210. The power transmission through the motor 211 via the main pulley 212 and the secondary pulley 210 drives the shaft 21 to rotate and the reciprocating motion assembly to move.

[0031] In this embodiment: A guide assembly for guiding the added plastic sheet is provided on the box body 11 below the guide plate 15. The guide assembly includes two horizontally arranged crushing rollers 213. One end of the crushing roller 213 passes through the box body 11 and is equipped with a meshing second gear 214. The other end of one crushing roller 213 is equipped with a first transmission pulley 215. A second transmission pulley 216 opposite to the first transmission pulley 215 is installed on the rotating shaft 21. A belt is sleeved between the first transmission pulley 215 and the second transmission pulley 216. The crushing roller 213 is rotatably connected to the box body 11. Power is transmitted through the second transmission pulley 216 on the rotating shaft 21 and the first transmission pulley 215 on the crushing roller 213. The crushing roller 213 is also driven by the meshing second gear 214 on the crushing roller 213, so that the crushing roller 213 squeezes and limits the added plastic waste sheet, ensuring the stability of the plastic waste sheet entering the ring blade 22.

[0032] The working principle and usage process of this utility model are as follows: The cut plastic waste sheets are added to the box 11 through the feed hopper 12. The power is transmitted through the main pulley 212 and the auxiliary pulley 210 by the motor 211. At the same time, the first gear 23 on the rotating shaft 21 meshes and rotates, causing the rotating shaft 21 and the ring cutter 22 to rotate relative to each other. The second transmission pulley 216 on the rotating shaft 21 and the first transmission pulley 215 on the crushing roller 213 transmit power, and the second gear 214 on the crushing roller 213 meshes with the plastic waste sheets. The crushing roller 213 squeezes and limits the added plastic waste sheets, causing the plastic waste sheets to be cut into strips by the relatively rotating ring cutter 22. At the same time, the turntable 24 at the end of the rotating shaft 21 rotates, driving the drive rod 25 to drive the connecting rod 27 to pull the shearing seat 28 to move back and forth under the support of the support seat 26. The shearing blade 29 on the shearing seat 28 cuts the plastic strips. The cut waste particles fall from the discharge port 14.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
