[0002] At present, a Chinese utility model with announcement number CN215589893U discloses a feeding device for a twin-screw extruder, including a cabinet door and an extruder body, a cabinet door is provided at the front end of the extruder body, an extrusion screw is provided inside the extruder body, a working motor is provided at the right end of the extruder body, a control box is provided on the left side of the upper end of the extruder body, two fixing parts are provided on the periphery of two fixing plates fixed to the feed hopper and the transmission cylinder, the two fixing parts are both semicircular, the two fixing parts can be sleeved on the periphery of the two fixing plates, fixing holes are provided on the two fixing parts, the fixing holes on the two fixing parts are the same size as the fixing holes on the two fixing plates, and the fixing parts and the fixing plates are fixed by fixing bolts, so that even if the fixing bolts are loose, there will be no gap between the two fixing plates.

[0003] Although the existing feeding device has a good fixing effect with the extruder and there will be no gap, there are still other problems during use. For example, it does not have the function of preventing materials from being blocked. When sticky materials are put in, they are easy to adhere to the inner wall of the hopper during the falling process. As the materials accumulate more and more, blockage is likely to occur, which increases the cleaning burden of personnel and is not convenient for quick disassembly and assembly of the device. The device needs to be removed from the extruder for cleaning, and tools are needed to assist in disassembling and assembling the screws on the device. The operation is cumbersome and complicated, which reduces the cleaning efficiency of personnel. In order to solve the above-mentioned problems, we propose a feeding device for testing screw extruders. Utility Model Content

[0017] The utility model is further configured as follows: the limit spring is made of carbon spring steel.

[0018] By adopting the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model first fixes the bottom plate to the screw extruder with screws. After the bottom plate is fixed, the fixing plate is grasped by hand to lift it up and fingers are separated to grasp the pull plate and pull it inward. When the pull plate is pulled, it drives the card plate to move inward through the fixation of the fixing rod, and then the bottom end of the hopper is placed in the fixed cylinder. When the hopper falls to the bottom, the hands can be released. It can be convenient to quickly disassemble and assemble the device, the operation is simple and convenient, and the cleaning efficiency of the personnel is improved.

[0021] 2. The utility model feeds the material inward from the feed frame, and starts the motor when the material is fed in. After starting, the motor drives the rotating rod to rotate through the cooperation of the bearing. When the rotating rod rotates, it drives the scraper to rotate along the inner wall of the hopper through the cooperation of the fixing part. It can have the function of preventing materials from being blocked, and automatically scrapes off the materials adhered to the inner wall, reducing the burden of manual dredging for personnel, and has high practicality.
