Description

Technical Field

[0001] This utility model relates to the field of pelletizer technology, specifically to a pelletizer with a multi-stage pelletizing mechanism. Background Technology

[0002] In the pelletizing process of industries such as plastics and chemical fibers, traditional pelletizers typically adopt a single-channel feeding and fixed-gap pressure roller design. The gap between the fixed roller shafts cannot be flexibly adjusted, making it difficult to accommodate strip-shaped materials of different diameters or hardness. When changing products, the machine must be stopped for manual adjustment, which is inefficient. Furthermore, the single-channel design results in a limited pelletizing capacity per unit time, making it difficult to meet high-output demands. Manual adjustment of the pressure roller gap also poses a safety hazard due to the risk of contact with moving parts. Therefore, a new technical solution needs to be designed to address these issues.

Then, the device is powered on and controlled by the control system. The pelletizing structure is then driven to work, and one end of the plastic material is embedded between the moving roller 11 and the fixed roller 6. According to the thickness of the plastic material, the adjusting screw 12 in the fixed plate 8 is turned. The adjusting screw 12 moves within the fixed plate 8, pushing the moving frame 10 and the two movable rods 9 to move within the fixed plate 8, changing the distance between the moving roller 11 and the fixed roller 6. Then, the first motor 7 on one side of the fixed frame 5 is driven to work. The first motor 7 drives the fixed roller 6 to rotate, conveying the plastic material between the fixed roller 6 and the moving roller 11.
