First, the device improves the layout and form of the main shaft hob assembly and hob, and adds fixed blades to the blanking screen, effectively improving the material tearing efficiency and breaking effect. Second, the feeding port is moved from the top of the main shaft hob assembly to the position above the material accumulation box, and the hob becomes more rounded and easier to rotate, greatly reducing the impact on the main shaft hob when the material is fed, ensuring the safety and stability of the device. Finally, a material loosening swing assembly is added to the feeding hopper, and the arc plate is inserted into the square notch of the feeding hopper, solving the problem of material being constantly lifted above the main shaft hob, ensuring smooth material entry into the device. In summary, the improved device only requires one worker to operate, further reducing labor costs.
