These pellets can then be reused as raw materials in the production process to manufacture new plastic products, thereby achieving resource recycling and reducing environmental pollution.

[0003] Patent publication number CN210362029U discloses an environmentally friendly granulator for recycling waste plastics. This granulator mainly includes a base, with a motor and a cutting box fixedly connected to the upper surface of the base. Inside the cutting box, a rotating shaft is rotatably connected via bearings.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: A pelletizer for recycling waste plastics, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 5The system includes a support platform 1, a feeding cylinder 2, a support shell 4, heating lamps 5, an insulation shell I 6, a heater 7, a heating tube 8, a feeding pipe 9, a drive motor 10, threaded blades 11, a feeding hopper 12, a collection frame 26, and a handle 27. The feeding cylinder 2 is fixedly connected to the support platform 1. The support shell 4 is fixedly connected to the top of the feeding cylinder 2. Several heating lamps 5 are installed inside the support shell 4. The insulation shell I 6 is fixedly connected to the outside of the feeding cylinder 2. A heater 7 is installed on the insulation shell I 6. A heating tube 8 is connected to the heater 7 and wound around the feeding cylinder 2. The feeding pipe 9 is fixedly connected to the bottom of the feeding cylinder 2. The drive motor 10 is bolted to the rear of the feeding pipe 9. Threaded blades 11 are connected to the output shaft of the drive motor 10. The bottom of the feeding pipe 9 is fixedly connected to... The equipment is equipped with several hoppers 12. A collection frame 26 is slidably installed on the front side of the support platform 1. A handle 27 is fixedly connected to the front side of the collection frame 26. Several filters 3 are installed inside the discharge cylinder 2. An anti-slip sleeve 28 is fitted on the handle 27 to increase the friction between the hand and the handle 27, thereby preventing the hand from slipping. Transparent plates 29 are embedded on both sides of the discharge pipe 9, allowing easy observation of the inside of the discharge pipe 9. Foot pads 30 are installed on both sides of the support platform 1. The foot pads 30 can increase the friction between the support platform 1 and the ground, preventing the equipment from sliding or moving during operation and ensuring the stability of the equipment. The foot pads 30 are usually made of elastic material, which can absorb the vibration generated during the operation of the granulator and reduce the transmission of noise.

[0026] When it is necessary to recycle and granulate waste plastics, first turn on the heating lamp 5, then feed the plastic fragments into the support shell 4. The heating lamp 5 generates heat to completely melt the plastic fragments. Then turn on the heater 7 to generate heat. This heat is transferred to the feeding cylinder 2 through the heating pipe 8 to increase the fluidity of the molten plastic. The melted and increased flow plastic enters the filter 3, which filters and removes impurities carried in the molten plastic to ensure the purity of subsequent processing and thus improve the quality of plastic granules. The filtered molten plastic enters the feeding pipe 9. Then, start the drive motor 10. The output shaft of the drive motor 10 rotates, driving the threaded blades 11 to rotate, squeezing the molten plastic out of the feeding hopper 12 and dropping it into the collection frame 26, completing the granulation process.

[0027] Example 2: Based on Example 1, please refer to... Figure 2 and Figure 3 Several hoppers 12 are fixedly connected to an insulation shell II 16. A support plate 13 is fixedly connected to the rear side of the insulation shell II 16. A cooler 14 is installed on the support plate 13 by bolt connection. A circulation pipe 15 is connected to the cooler 14 and is wound around the hopper 12.

[0028] Before the molten plastic is extruded from the hopper 12, the cooler 14 is turned on. The cooler 14 generates cold air, and the circulation pipe 15 transfers the cold air to the hopper 12. The hopper 12 then cools the molten plastic inside, allowing the molten plastic to cool down and solidify quickly, thereby improving the granulation effect.

[0029] Please see Figure 3 and Figure 4 A support frame 17 is bolted inside the support shell 4. A rotating bucket 18 is rotatably mounted inside the support shell 4. A servo motor 19 is bolted onto the support frame 17. The output shaft of the servo motor 19 is connected to the rotating bucket 18. A scraper 20 is bolted inside the support shell 4 and contacts the rotating bucket 18.

[0030] When the plastic fragments are heated and melted, the servo motor 19 is started. The output shaft of the servo motor 19 rotates, which drives the rotating bucket 18 to rotate, so that the scraper 20 can effectively handle the molten plastic fragments inside the rotating bucket 18 and prevent residue.

[0031] Please see Figure 3 , Figure 5 and Figure 6 The support platform 1 is equipped with a fixed frame 21 by bolt connection. A dual-axis motor 22 is installed on the fixed frame 21 by bolt connection. The two output shafts of the dual-axis motor 22 are connected to lead screws 23 by couplings. A guide plate 25 is fixedly connected inside the support platform 1. Two cutting blades 24 are slidably installed on the guide plate 25. The cutting blades 24 are threadedly connected to the lead screws 23.

[0032] After the molten plastic is extruded from the hopper 12, the dual-shaft motor 22 is started. The output shaft of the dual-shaft motor 22 rotates, which drives the lead screw 23 to rotate, causing the two cutting blades 24 to move inward and cut the extruded plastic into small particles of uniform length, thus eliminating the need for subsequent cutting and improving granulation efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
