Description

Technical Field

[0001] The utility model relates to the field of engineering plastic processing, in particular to a pelletizing mechanism for engineering plastic processing. Background Art

[0002] At present, a Chinese utility model with announcement number CN220499222U discloses a plastic product pelletizer with a preheating structure, including a support plate, a pelletizer, a collecting trough, a preheating mechanism, and a screening mechanism. The pelletizer is fixed on the surface of the support plate, and a collecting trough is provided at the end of the discharge plate away from the pelletizer. The plastic product pelletizer with a preheating structure provided in the present application has a hardened material after storage, and the stored plastic strips are softened after the preheating mechanism is used, and then the blade damage can be effectively avoided during production pelletizing, and the production efficiency can be improved. In addition, the screening mechanism is used to enable the pelletizer to screen out smaller plastic pellets from the screen during pelletizing, and then pass through the holes and fall to the bottom of the support plate, which can effectively improve the production quality and qualified rate.

[0003] The existing pelletizing mechanism is not convenient for replacing the roller. The roller needs to be replaced after being used for a long time. The roller is generally installed inside the device and fixed by bolts. When replacing it, it is necessary to use tools to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of replacement. It is also not convenient to adjust the pressure of the rubber roller. Generally, the pressure between the rubber roller and the conveying roller is fixed. After long-term use, the pressure between the rubber roller and the conveying roller will change. To adjust it, the rubber roller is fixed by bolts. When adjusting, it is necessary to use tools to disassemble the rubber roller and install it after adjustment. The adjustment accuracy is poor and sometimes it is adjusted multiple times, which is very troublesome, increases the work and reduces the work efficiency. In order to solve the above-mentioned problems, we propose a pelletizing mechanism for engineering plastic processing. Utility Model Content
