[0002] TPE is also commonly known as thermoplastic elastomer, artificial rubber or synthetic rubber. Its products have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, while also having the characteristics of easy processing and wide processing methods of ordinary plastics. It is a more humane and high-grade new synthetic material, and is also a world-standard environmentally friendly material. In the production process of TPE, a pelletizer is needed to cut the TPE material into small particles or sheets, so as to provide convenience for the staff's subsequent processing and sales.

[0003] However, the current pelletizers still have some shortcomings. For example, the existing pelletizers have poor automatic screening functions, which leads to the residue of debris in the TPE pellets produced, thereby causing certain interference to the subsequent processing and sales of the staff, and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structural deficiencies and provides a TPE production pelletizer. Utility Model Content

The screening net 94 and the connecting plate 92 of the structure are so designed that the impact force of the TPE plastic particles falling on the top of the screening net 94 can drive the screening net 94 to vibrate slightly, thereby improving the screening effect of the screening net 94. At the same time, the screening net 94 is arranged in parallel just below the outer shell 1. The top of the supporting bracket 91 is fixedly connected to the support column 95, and the top of the support column 95 is fixedly connected to the bottom of the outer shell 1. In addition, the impurity recovery component 10 is slidably connected to the inner surface of the bottom of the screening component 9, and the impurity recovery component 10 includes an impurity recovery box 10. 1. A rectangular slide 102 and a handle 103, and a rectangular slide 102 is symmetrically installed on the bottom of the impurity recovery box 101, the bottom of the impurity recovery box 101 is fixedly connected to the top of the rectangular slide 102, and the impurity recovery box 101 forms a sliding structure with the supporting bracket 91 through the rectangular slide 102. By setting the impurity recovery box 101 and the supporting bracket 91 as a sliding structure, the impurity recovery box 101 is easy for the staff to take out for subsequent recycling processing, and a handle 103 is fixedly installed on the outside of the impurity recovery box 101.

[0023] like Figure 1 and Figure 2As shown, a first motor 2 is installed on the side of the outer shell 1, and a cutting mechanism 3 is installed on the output shaft of the first motor 2 through a coupling, and the cutting mechanism 3 is rotatably connected to the inside of the outer shell 1, and a supporting plate 4 is symmetrically installed on the outside of the outer shell 1, and a second motor 5 is installed on the outside of the supporting plate 4.

When the first motor 2 starts running, it drives the cutting mechanism 3 to rotate inside the outer shell 1. When the second motor 5 starts running, the two connecting shafts 61 are synchronously rotated in opposite directions inside the carrying plate 4 through the connection of the transmission gear 64. Then the staff conveys the TPE plastic extruded by the extruder to the conveying roller 62, and then conveys the plastic into the inner part of the outer shell 1 through the cooperation of the conveying roller 62. At this time, the plastic is pelletized by the rotation of the cutting mechanism 3 and the support of the fixed plate 7. Then the prepared particles are conveyed to the top of the screening component 9 through the guide plate 8. At this time, the impact force generated when the TPE particles fall drives the screening net 94 to vibrate through the cooperation of the buffer spring 93 at the top of the connecting plate 92, so that the screening net 94 automatically screens the particles, wherein fine impurities fall into the interior of the impurity recovery component 10 for automatic collection and processing, and the particles are discharged through the side of the supporting bracket 91 and fall into the collection box for collection and processing.
