Description

Technical Field

[0001] This utility model relates to the field of anti-clogging hopper technology, and in particular to an anti-clogging hopper for powder coating production. Background Technology

[0002] A powder coating production hopper is a device used in the powder coating production process to transport powder coating from the inlet to the next process. Due to the characteristics of powder coating having a certain viscosity and poor flowability, it is easy to adhere to the inner wall of the hopper during the production process, resulting in blockage, which affects production efficiency and continuity. In view of this, it is necessary to improve the current anti-blockage hopper to solve the above problems.

[0028] With this design, a rubber dustproof sheet 52 with a cross-shaped groove 53 is set on the upper part of the feed inlet 41 through a circular ring 51. When the conveying pipe extends into the hopper body 101 through the feed inlet 41, the rubber dustproof sheet 52 is in contact with the outer wall of the conveying pipe, thereby reducing the amount of powder material flying up and causing pollution to the working environment.

[0029] The inner wall of the hopper body 101 is provided with an inverted conical shell 7. A servo motor 9 is provided inside the inverted conical shell 7. The output end of the servo motor 9 is fixed to a rotating shaft 10 through a coupling. The rotating shaft 10 passes through the top surface of the inverted conical shell 7.

The outer wall of the detachable structure 12 is set as a column 121, the top surface of the column 121 is set as a cone 122, and the cone 122 is located directly below the feed port 41.

[0031] With this design, the cone 122 is placed on the column 121 of the detachable structure 12, and the cone 122 is located directly below the feed inlet 41, which can reduce the deposition of powder materials on the top of the detachable structure 12.

[0032] In other embodiments, spring cavities 15 are provided at equal intervals on the side of the L-shaped scraper 14 opposite to the detachable structure 12.

The limiting piece 131 is slidably fitted inside the spring cavity 15. A spring 151 is provided between one side of the limiting piece 131 and one side of the L-shaped scraper 14.

[0033] With this design, when the spring 151 is in a compressed state, one side of the L-shaped scraper 14 is in close contact with the inner wall of the hopper body 101, wherein the L-shaped scraper 14 is made of rubber.

[0034] In other embodiments, the controller 6 is electrically connected to the servo motor 9 and the solenoid valve 8, respectively;

[0035] Through this design, the servo motor 9 and the solenoid valve 8 are electrically connected to the controller 6, thereby facilitating the operator to use and control the hopper through the controller 6;

[0036] In this embodiment, by setting an L-shaped scraper on the inner wall of the hopper body and by setting a spring cavity with a spring, when the spring is in a compressed state, one side of the L-shaped scraper fits tightly against the inner wall of the hopper body, thereby improving the cleaning efficiency of powdery materials on the inner wall and avoiding blockage.
