Technical Field

[0001] This utility model relates to the field of plastic cutting, and in particular to a plastic granule cutting machine. Background Technology

[0002] Plastic cutting machines are used to cut strips of plastic extruded from an extruder into granules. Existing plastic granulator cutting machines, after cutting the plastic, will screen out appropriately sized plastic granules as needed. Generally, after cutting, the granules enter a screening structure for sieving. However, the plastic granulation process generates debris, and existing cutting machines lack a structure for timely debris removal. This debris easily enters the screening structure along with the plastic granules, affecting the screening effect. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a plastic granule cutter that facilitates timely cleaning of debris and does not easily affect the screening effect.

[0004] The technical solution of this utility model is as follows:

[0018] The beneficial effects of this utility model are:

[0019] 1. The conveying assembly can convey strip-shaped plastics. The strip-shaped plastics enter between multiple guide plates and are guided by the gaps between the guide plates, so that the strip-shaped plastics are neatly conveyed to the bottom of the cutting blade. The hydraulic rod can drive the cutting blade to cut the strip-shaped plastics into granules. During cutting, the cutting edge of the cutting blade can penetrate the cutting slit, so that the cutting blade has a complete cutting space. The cut debris can fall into the waste chamber through the cutting slit for collection, preventing the debris from falling into the screening assembly.

Detailed Implementation

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example:

[0029] like Figures 1-2 As shown, a plastic pellet cutting machine includes a worktable 10, a cutting assembly, a guiding assembly, a conveying assembly, and a screening assembly. The screening assembly is located on one side of the worktable 10 and includes a screening trough 21 and a screening plate 22. The screening plate 22 is located in the middle of the screening trough 21 and has holes for plastic pellets of appropriate size to pass through. The screening plate 22 can be replaced as needed. The bottom of the screening trough 21 is provided with a discharge port.

[0030] The cutting assembly is located on the workbench 10 near the screening assembly and includes a support frame 31, a hydraulic rod 32, and a cutting blade 33. The support frame 31 is a portal frame and is fixedly mounted on the workbench 10. The hydraulic rod 32 is vertically mounted in the middle of the top of the support frame 31. The cutting blade 33 includes a blade holder 331 and a blade 332. The bottom side of the blade holder 331 has a slot for inserting and installing the blade 332. A connection hole can be opened on the blade 332. The side wall of the blade holder 331 has a screw hole corresponding to the connection hole, through which bolts can be inserted to connect the blade holder 331 and the blade 332. The movable end of the hydraulic rod 32 passes through the top of the support frame 31 and connects to the blade holder 331 of the cutting blade 33. A waste chamber is opened inside the workbench 10, and a cutting slit 11 communicating with the waste chamber is provided on the workbench 10 directly below the cutting blade 33.

[0031] The conveying assembly is located on the side of the worktable 10 away from the cutting assembly, and includes a motor 41, a side plate 42, a drive roller 43 and a driven roller 44. The side plate 42 includes two pieces, which are respectively located on opposite sides of the worktable 10. The drive roller 43 and the driven roller 44 are rotated one up and one down between the two side plates 42. The motor 41 is located on the outside of one of the side plates 42 and drives the drive roller 43.

[0032] The guide assembly is located between the cutting assembly and the screening assembly, and includes a base plate 51 and multiple guide plates 52. The base plate 51 is located on the top of the workbench 10, and the multiple guide plates 52 are vertically arranged at equal intervals on the base plate 51. The gap between the guide plates 52 is directed towards the conveying assembly and the cutting assembly.

[0033] The working principle of the above technical solution is as follows:

[0034] After the extruder extrudes strip-shaped plastic, the strip-shaped plastic passes through the drive roller 43 and the driven roller 44. Along the direction from the conveying assembly to the guide cutting assembly, one end of the strip-shaped plastic is pulled between the guide plates 52 of the guide assembly. The starting motor 41 can drive the drive roller 43 to rotate, extruding the strip-shaped plastic. When the strip-shaped plastic reaches the cutting slit 11, the hydraulic rod 32 is activated to lower the cutting blade 33 to cut the strip-shaped plastic. The cut-off debris falls into the waste chamber for collection through the cutting slit 11, while the cut-off plastic particles fall into the screening tank 21. Plastic particles that meet the requirements pass through the screening plate 22 and fall out from the discharge port.

[0035] In another embodiment, such as Figure 1 As shown, a pull-out opening is provided on one side of the waste chamber of the workbench 10, and a waste bin 12 that can be pulled out from the pull-out opening is provided inside the waste chamber.

[0036] The waste chamber is equipped with a waste bin 12 for storing debris, which facilitates the removal and transfer of collected debris.

[0037] In another embodiment, such as Figure 1 As shown, the two inner sidewalls of the support frame 31 are provided with guide grooves 311, and the two sides of the tool holder 331 are provided with guide blocks 333 that are slidably connected to the guide grooves 311.

[0038] The guide groove 311 of the support frame 31 can provide stable guidance for the up and down movement of the cutting blade 33, making the operation of the cutting blade 33 more stable.

[0039] In another embodiment, such as Figure 1As shown, a pressing component is provided on the side of the knife holder 331 away from the screening component. The pressing component includes a connecting block 61 and a pressing block. The pressing block and the knife holder 331 are respectively connected to the two sides of the connecting block 61. The pressing block includes a fixed block 62 and a movable block 63. The fixed block 62 is connected to the connecting block 61. The bottom of the fixed block 62 is provided with a movable groove. The top of the movable block 63 is retractably located in the movable groove. The inside of the movable groove is also provided with a spring 64 connecting the bottom of the movable groove and the movable block 63.

[0040] When the cutting blade 33 acts on the strip of plastic, the plastic on both sides of the cutting blade 33 tends to lift up. When the pressing component is used to press down, the top of the movable block 63 retracts into the movable groove of the fixed block 62. This ensures that the plastic is pressed tightly while avoiding excessive compression that could cause excessive deformation of the plastic. The pressing component can ensure the cutting effect and produce more regular plastic particles.

[0041] In another embodiment, such as Figure 1 As shown, the screening trough 21 is lower than the top surface of the workbench 10, and the top of the workbench 10 is provided with an inclined side of the screening trough 21 on the side close to the top of the screening trough 21.

[0042] This facilitates the falling of the cut plastic granules into the screening tank 21.

[0043] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
