Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism of a mixer. Background Art
[0002] At present, the feeding mechanism of the paint mixer is mostly directly fixed to the feeding hopper on the top of the mixer. The feeding hopper of the paint mixer is mostly open. When adding materials, the user directly aligns the paint bag with the feeding hopper to add powdered paint. However, after the dry powder paint is added, the powder rises upward due to air resistance during the downward throwing process, which easily causes dust leakage and affects the working environment. At the same time, the current feeding hopper is on one side of the mixer, and the added materials are also concentrated on one side of the mixer. The center of the material cannot quickly contact with water, which easily produces lumps. When stirring, the mixer needs to spend a lot of time to break up the powder lumps, which affects the stirring efficiency. Utility Model Content

[0006] Preferably, any of the above schemes has an opening on one side of the top of the feed hopper fixedly connected to a collecting hopper, and a bottom opening of the collecting hopper is connected to the inside of the feed pipe through the feed hopper.
[0007] The technical effect achieved by adopting the above scheme is that materials can be easily added and concentrated through the gathering bucket.

[0014] Compared with the prior art, the advantages and beneficial effects of the utility model are:
[0015] 1. The feeding mechanism of the mixer blocks the opening at the bottom of the feed hopper through a one-way flap, so that after the powder is added, the powder automatically pushes the one-way flap open under the force of gravity and enters the feed pipe. When adding, the material and the one-way flap block the outlet at the same time. After the powder is completely added, the one-way flap falls down to block it, reducing dust leakage.
