[0033] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0034] In conjunction with Figure 1, A cutting device for recycled polyester chips of the present utility model includes a base 1. A filter box 2 is fixedly connected to the right side of the top of the base 1. A cutting box 3 is fixedly connected to the top of the filter box 2. A connecting plate 9 is fixedly connected between the inner walls of the cutting box 3. Two first cylinders 10 are fixedly connected to the bottom of the connecting plate 9. A cutting knife 11 is fixedly connected to the output ends of the two first cylinders 10. A conveyor belt 4 is arranged on the left side of the inner wall of the cutting box 3.

A conveying pipe 8 penetrates and is fixedly connected to the top of the right side of the outer diameter of the conveying bin 6.

[0035] When the conveyor belt 4 is working, it can convey the chips. Then when it moves below the cutting knife 11, the cutting work is carried out. After that, it enters the screening work link. The qualified ones will pass through the screening plate 23, and the unqualified ones will be conveyed into the cutting box 3 again.

[0036] Combined with Figure 2 - Figure 4 , Limiting plates 33 are slidably connected to the inner walls of the two slide grooves 34. A screening plate 23 is fixedly connected between the two limiting plates 33. Two limiting grooves 25 are formed at the position slightly above the center of the right side of the outer wall of the filter box 2. Limiting rings 29 are fixedly connected to the inner diameters of the two limiting grooves 25. Pull rods 35 are arranged in the inner diameters of the two limiting rings 29. Springs 30 are sleeved on the surfaces of the two pull rods 35. Pressure plates 27 are fixedly connected to the surfaces of the two pull rods 35. Convex blocks 28 are fixedly connected to one side of the two pressure plates 27. Two square grooves 26 are formed at the position slightly below the center of the right side of the outer wall of the filter box 2. A screening component is arranged on the right side of the top of the base 1.

[0037] When installing the screening plate 23, the pressure plate 27 can be rotated and aligned with the position of the square groove 26. When the pinch block 31 is released, the convex block 28 can enter the square groove 26 for clamping, and then the screening plate 23 is limited.

[0038] Combined with Figure 5, the screening assembly includes a first motor 5, which is fixedly connected between the base 1. The output end of the first motor 5 penetrates through the conveying bin 6 and is fixedly connected with a spiral feeding rod 7. The front end inner wall of the filtering box 2 is fixedly connected with a first slide rail 13. The right end outer wall of the filtering box 2 is fixedly connected with a support plate 16. The top of the support plate 16 is fixedly connected with a second motor 15. The output end of the second motor 15 penetrates through the filtering box 2 and is fixedly connected with a lead screw 14. A nut pair 17 is threadedly connected to the surface of the lead screw 14. The rear side inner wall of the filtering box 2 is fixedly connected with a second slide rail 18. A slider 19 is slidably connected to the inner wall of the second slide rail 18. Both the slider 19 and the bottom of the nut pair 17 are fixedly connected with a second cylinder 20. The output ends of both second cylinders 20 are fixedly connected with a connecting block 21. A push plate 22 is arranged between the two connecting blocks 21. The tops of both the first slide rail 13 and the second slide rail 18 are fixedly connected with an inclined plate 12. The left side of the inner wall of the first slide rail 13 is rotatably connected with a lead screw 14. The first slide rail 13 and the nut pair 17 are slidably connected. The left end of the outer wall of the filtering box 2 penetrates and is fixedly connected with a discharge pipe 24. The left end of the discharge pipe 24 penetrates and is fixedly connected with the conveying bin 6.

[0039] When the cut slices enter the screening plate 23 and fall above the inclined plate 12, they will not pile up due to the inclination. Then, when the push plate 22 moves, it can push the slices to move, accelerating the screening. At the same time, after the screening is completed, the slices that cannot be screened can be pushed into the conveying bin 6, cut again, and then screened.

[0040] Working principle: When using the cutting device, first place the slice to be cut above the conveyor belt 4. The conveyor belt 4 operates to convey the slice. Then start the first cylinder 10 to drive the cutting knife 11 to move downward for cutting. After cutting, it will fall above the screening plate 23. Start the second motor 15 to operate, which can drive the lead screw 14 to rotate, and then drive the nut pair 17 to move, thereby pulling the slider 19 on the other side to slide within the second slide rail 18. Start the second cylinder 20 to drive the push plate 22 to move downward and fit with the screening plate 23, which can drive the push plate 22 to toggle the slice to accelerate screening. After screening, the unscreened slices can be pushed into 36 and then enter the conveying bin 6. Start the first motor 5 to operate, which can drive the spiral feeding rod 7 to rotate, convey the unscreened slices again and let them fall above the conveyor belt 4 for cutting again, effectively improving the screening effect. The slices passing through the screening plate 23 will be collected by the collection box 32. When the screening effect of the screening plate 23 deteriorates, the pinch block 31 can be used to pull the pull rod 35 to slide within the limit ring 29. Then the spring 30 contracts, and the convex block 28 separates from the square groove 26. Then the pull rod 35 can be rotated, and then the pressing plate 27 rotates. After that, the screening plate 23 can be pulled, and the limit plate 33 slides within the chute 34, so as to take out the screening plate 23 for replacement. After the replacement is completed, the pull rod 35 can be pulled again to rotate the pressing plate 27, and align the convex block 28 with the square groove 26. Then release the pull rod 35, and the acting force of the spring 30 can make the pressing plate 27 limit the screening plate 23, which is convenient for replacement.

[0041] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or sequence between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
