Automatic painting device
Technical Field
The invention relates to the technical field of paint brushing equipment, in particular to an automatic paint brushing device.
Background
In building decoration, paint is an indispensable material, and paint brushes are widely used as tools for painting, but in the prior art, manual paint brushes have the following defects:
1. the paint must be repeatedly dipped by the brush hair in use, so that the paint is easy to drip on the way to cause waste, and the dripped paint is difficult to clean and seriously pollutes the environment.
2. People have interrupted the working process of brushing paint when repeatedly dipping in and getting paint, very big influence work efficiency.
3. In the process of brushing paint, the brush needs to be repeatedly operated up and down or left and right, workers need to bend the bristles by force so that the bristles can smoothly operate, and the joint of the bristles and the brush handle is broken due to frequent bending or extrusion force after the brushes are operated for a long time, so that the paint brush is frequently replaced, and the cost is increased.
In some improved paint brushes, a container for containing paint is arranged on the brush, but the paint liquid automatically flows into the brush bristles completely depending on the amount of the paint liquid flowing into the brush bristles, the amount of the paint liquid flowing into the brush bristles cannot be controlled, the paint liquid is scattered on the ground when the amount of the paint liquid is large, the paint liquid is cut off frequently when the amount of the paint liquid is small, and the paint brush cannot be used at all in practice.
