[0024] The plastic particle forming adjustment component includes a discharge pipe 6 that is communicated with the outlet of the mother-feeding pipe 4. Bolts 7 are symmetrically threadedly connected to the discharge pipe 6, and the bolts 7 are threadedly connected to the outer wall of the mother-feeding pipe 4. A number of discharge holes 8 are evenly provided on the discharge pipe 6. A guiding groove 9 is fixedly installed on the discharge pipe 6 corresponding to the discharge holes 8. The other end of the guiding groove 9 is fixedly installed with a fixing plate 10. A support rod 11 is fixedly installed on the bottom plate 1 corresponding to the fixing plate 10. A rotating block 12 is rotatably connected to the support rod 11. A number of grooves 13 are evenly provided on the rotating block 12. Through holes 14 are provided on the rotating block 12 corresponding to the grooves 13. A cutting knife 15 is inserted and connected in the grooves 13. A limiting rod 16 is inserted and connected to the through holes 14, and the limiting rod 16 is inserted and connected to the cutting knife 15. A support frame 17 is fixedly installed on the bottom plate 1, and a driving motor 18 is fixedly installed on the support frame 17. The output end of the driving motor 18 is fixedly connected to the rotating block 12;
[0025] As can be seen from the above description, the raw materials of the plastic first enter the sub-feeding pipe 3 through the funnel 5. After being conveyed by the internal spiral conveying rod, they enter the mother-feeding pipe 4. After being heated and melted by an external device, they are finally discharged through the discharge pipe 6. After being discharged through the discharge hole 8, they enter the guiding groove 9 and finally enter the fixing plate 10, where they are cut by the cutting knife 15 to form a granular state. Before processing, it is necessary to select the discharge pipe 6 and install and use a discharge hole 8 of a suitable size. The discharge pipe 6 is interconnected with the mother-feeding pipe 4 through the bolt 7. Then, regarding the length problem of the required particles, the corresponding cutting knife 15 is inserted at the position of the groove 13 and fixed by the limiting rod 16, so that there can be different numbers of cutting knives 15 on the rotating block 12, and the frequency of the rotating block 12 during cutting will change, thereby realizing the adjustment of plastic particles of different lengths.
[0026] As a technical optimization scheme of the present utility model, a filter screen 19 is provided on the funnel 5 located on the sub-feeding pipe 3;
[0027] As can be seen from the above description, the filter screen 19 can filter large-particle substances in the plastic raw materials to prevent blockage of the sub-feeding pipe 3.
[0028] As a technical optimization scheme of the present utility model, a partition plate 20 is fixedly installed at the discharge port of the sub-feeding pipe 3;
[0029] As can be seen from the above description, the partition plate 20 can prevent the plastic raw materials from spreading out during falling, causing environmental pollution to the bottom plate 1 and the entire working station.
[0030] As a technical optimization scheme of the present utility model, a plurality of strip-shaped through holes 21 are evenly provided on the guiding groove 9;
[0031] As can be seen from the above description, the strip-shaped through holes 21 can dissipate heat from the strip-shaped plastic located in the guiding groove 9, or external corresponding air-cooling equipment or water-cooling equipment can be connected for cooling, so that the plastic can be quickly cooled to a suitable range, facilitating the subsequent cutting work.
[0032] As a technical optimization scheme of the present utility model, the limiting rod 16 is magnetically connected to the rotating block 12;
[0033] As can be seen from the above description, through the magnetic connection method, the limiting rod 16 can be quickly and effectively fixed on the rotating block 12, making the installation and disassembly more convenient.
[0034] As a technical optimization scheme of the present utility model, the cutting knife 15 is slidably connected to the outer surface of the fixing plate 10;
[0035] As can be seen from the above description, such a connection method enables the outer surfaces of the cutting knife 15 and the fixing plate 10 to fit together, resulting in a better cutting effect when cutting plastics.
[0036] Working principle:
[0037] The raw material of the plastic first enters the sub-feeding pipe 3 through the funnel 5. After being conveyed by the internal spiral conveyor rod, it enters the mother-feeding pipe 4. After being heated and melted by an external device, it finally exits through the discharge pipe 6. After exiting through the discharge hole 8, it enters the guiding groove 9 and finally enters the fixing plate 10, where it is cut by the cutting knife 15 to form a granular state. Before processing, it is necessary to select the discharge pipe 6 and install a discharge hole 8 with a suitable size for use. The discharge pipe 6 is connected to the mother-feeding pipe 4 through the bolt 7. Then, regarding the length of the required particles, the corresponding cutting knife 15 is inserted at the position of the groove 13 and fixed by the limiting rod 16, so that there can be different numbers of cutting knives 15 on the rotating block 12, causing the frequency of the rotating block 12 during cutting to change, thereby realizing the adjustment of plastic particles of different lengths.
[0038] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the specific implementation manners is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to the technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
