Description

Technical Field

[0001] The utility model belongs to the technical field of powder processing, and particularly relates to an anti-blocking feeding device for a powder coating hopper. Background Art

[0002] In the prior art, when using a hopper to feed powder coatings, a large amount of powder coatings are poured from the upper part of the hopper. Under the action of gravity, the powder coatings are discharged from the discharge port at the lower part of the hopper to a designated part. After retrieval, the patent application number "CN202222785424.6" discloses "an anti-blocking device for a powder coating hopper", which records that "the anti-blocking device for the powder coating hopper drives a gear to rotate through the rotation of a motor, so that an external gear ring rotates. Then, through the connection of a curved plate, an anti-blocking piece rotates on the inner wall of the hopper. At the same time, the anti-blocking piece pushes the powder coatings to enter the other side through a flow channel, so as to achieve the effect of preventing the powder coatings in the hopper from accumulating and blocking. By driving a scraper to scrape the powder coatings on the inner wall of the hopper through the rotation of the anti-blocking piece, the effect of preventing the powder coatings from adhering to the inner wall of the hopper is achieved". Using this anti-blocking device for the powder coating hopper to drive a gear to rotate through the rotation of a motor, so that the external gear ring rotates, and then through the connection of a curved plate, the anti-blocking piece rotates on the inner wall of the hopper. At the same time, the anti-blocking piece pushes the powder coatings to enter the other side through the flow channel, which indeed achieves the effect of preventing the powder coatings in the hopper from accumulating and blocking. By driving a scraper to scrape the powder coatings on the inner wall of the hopper through the rotation of the anti-blocking piece, the effect of preventing the powder coatings from adhering to the inner wall of the hopper is achieved. However, the above comparative document still has the following problems in actual use:

[0003] In actual use, only the outlet can be scraped to loosen the powder materials, while the powder materials inside the hopper cannot be loosened, resulting in the accumulation of powder coatings inside the hopper. At the same time, the inner wall of the hopper is extruded, and under the action of the extrusion force, an adhesive force is generated between the powder particles, and they still cannot be stably discharged. Moreover, when a blockage occurs during use, it cannot be quickly cleaned, and the working efficiency is poor.

[0004] Based on this, it is highly practical to provide a device that can loosen the powder materials in the hopper, avoid blockage caused by mutual force, and can be quickly cleaned when a blockage occurs. Summary of the Utility Model
