[0002] The furniture paint that people often talk about actually refers specifically to the special paint on the surface of wooden and bamboo furniture, also known as "wood paint". Furniture paint can make wooden and bamboo furniture more beautiful and bright, improve the rough feel of the furniture itself, and make the furniture not affected by climate and dry and wet changes. It not only plays a role in protecting and maintaining wooden and bamboo furniture, but also makes the whole family life more comfortable. At present, a large number of wooden furniture and wooden products are needed in people's indoor living environment. In order to improve the rough feel of wooden furniture and wooden products themselves and make the furniture not affected by climate and dry and wet changes, it is necessary to use furniture paint to package wooden furniture and wooden products. In the production process of existing furniture paint, it is necessary to add powder to the powder mixer for full stirring, so a feeding device is used to add materials to the mixer, so as to mix and process it. However, during the use of the existing feeding device, if there is agglomeration in the powder raw material, it is easy to affect the subsequent processing effect, and the blockage in the feeding device will cause the powder to be unable to enter the mixer, which will affect the stirring result.
