Description

Technical Field

[0001] The utility model belongs to the technical field of hair fiber production, and particularly relates to an automatic unloading device for a hair fiber raw material silo. Background Art

[0002] Currently, the main raw materials for hair fibers include polyester, nylon, and acrylic. These raw materials are crushed into powder or granules and then stored in a silo. A discharge pipe with a discharge valve is located at the lower end of the silo. During discharge, the valve is opened and the discharge speed is controlled by adjusting the valve opening, making it easy to operate. However, because the discharge pipe is thinner than the diameter of the silo, the upper end of the pipe is prone to clogging. Once clogged, no matter how the valve opening is adjusted, the material is difficult to discharge. Therefore, an automatic discharge device can be installed at the discharge pipe to clear the easily clogged upper end and guide the material downward, ensuring a smooth discharge of the material.

[0011] By adopting the above technical solution, compared with the existing technology, the utility model has the following beneficial effects:

[0012] (1) The utility model is arranged at the lower end of the discharge pipe.

[0016] (5) Due to the gravity of the drum, spokes, shaft and spiral blades, in order to reduce the friction between the lower end ring surface of the drum and the top surface of the lower shell, and to ensure the axial stability of the drum, and to reduce the axial force of the upper bearing and the lower bearing, a corresponding annular groove is specially set between the lower end surface of the drum and the upper surface of the lower shell, and a supporting ball is set in the annular groove, so that the sliding friction is converted into rolling friction, the friction force is small, and the rotation is more flexible.

[0017] To sum up, the utility model has a scientific principle and a compact structure. The unloading is transported downward by the spiral blades, which plays a good role in dredging and guiding the material, avoiding blockage at the upper port of the unloading pipe, and the unloading speed can be adjusted by adjusting the speed of the rotating blades (the speed of the power unit).
