After adopting the above technical scheme, the beneficial effect of the utility model is: a waste plastic cutting and kneading device, including a frame, a kneading barrel is installed on the frame, and the upper end and the lower end of the kneading barrel are respectively provided with feeding At least one fixed knife is installed horizontally on the inner side of the barrel wall of the kneading barrel, and a moving knife mounting seat is installed on the bottom of the kneading barrel, and at least one moving knife is horizontally installed on the moving knife mounting seat. The knife mounting seat is driven to rotate by a driving device. After all kinds of waste plastics are put into the kneading barrel, the driving device drives the moving knife mounting seat to rotate, thereby driving the waste plastics in the kneading barrel to continue to rotate at high speed. Rotate, generate heat through self-friction, make it reach a molten state in the kneading barrel, and stick together, and then through shearing, the waste plastic is finally kneaded into granules and discharged through the discharge port. The cutting and kneading device combines the cutting and kneading processes simultaneously, has simple process, low energy consumption, small occupied area, low cost and good kneading effect.

And because the valve is installed at the discharge port, the opening and closing of the valve is controlled by the cylinder, so that the waste materials can be fully melted and then sheared and kneaded, which ensures that the kneading can achieve better results.

Since the kneading barrel includes a feed hopper and a working barrel from top to bottom, the feeding hopper and the working barrel are detachably connected, the feed inlet is arranged at the upper end of the feed hopper, and the discharge outlet is arranged at the working barrel Therefore, the position of the feed inlet can be flexibly adjusted according to the actual production site, which facilitates the layout of the entire production line.

And because the barrel wall of the kneading barrel is wrapped with heat-insulating material, it is beneficial for waste plastics to quickly reach a molten state in the kneading barrel.
