Description

A powder supply center with integrated powder pump without powder bucket

technical field

The invention relates to a powder supply center of a powder spraying room, in particular to a powder supply center with an integrated powder pump and no powder bucket.

Background technique

In the existing powder supply center, the powder bucket is generally placed on the fluidized plate, and then the powder pipe is directly inserted into the powder bucket to absorb powder. When changing the powder color, the powder pipe needs to be pulled out, and then sealed with the high-pressure air pipe Connect, clean up the remaining powder in the powder pipe, powder pump and spray gun through the high-pressure air pipe. In the actual use process, the customer found the following defects in the above process: Since the connection between the powder tube and the powder bucket is open, the sealing effect is poor, and powder will continuously fly out of the connection during the powder suction process. Causes waste of powder and environmental pollution; in addition, when changing the color of the powder, the powder pipe needs to be pulled out and connected to the high-pressure air pipe. This process requires manual operation, which is inefficient and will cause the powder to fly out.

At the same time, the powder pumps in the existing powder supply center are all independent, which is not conducive to automatic operation. It is necessary to design a new powder supply center for this reason.
