Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying machines, in particular to a paint spraying machine. Background Art

[0002] A paint sprayer is a device used to coat surfaces, commonly used in industrial production and surface treatment. It sprays paint onto surfaces using high-pressure air, creating a uniform coating. Paint sprayers can apply a variety of liquid coatings, such as paint, coatings, and rust inhibitors, to a variety of surfaces, including metal, wood, and plastic.

[0003] A paint sprayer is disclosed in the utility model patent with patent authorization announcement number CN220004585U, which includes a body, a storage barrel fixedly installed on the top of the body, a hopper provided on the top of the storage barrel, a filter plate provided on the inner wall of the hopper, a frame fixedly connected to the outer wall of the hopper, a storage box provided on the inner wall of the frame, a micro motor symmetrically provided on the inner wall of the frame, and a threaded screw fixedly connected to the output end of the micro motor.

[0004] However, the existing paint spraying machine also has certain shortcomings. First, although the existing paint spraying machine uses components such as filters to filter out impurities from the raw materials, due to factors such as the adhesion characteristics of impurities, long-term use will cause the filter to become clogged.

[0005] Secondly, most existing paint sprayers simply use motors, stirring blades and other components to complete the stirring and mixing of the paint. Due to the adhesion characteristics of the paint, it is easy for the paint to adhere to the inner wall of the stirring tank, resulting in waste. In addition, when the motor output shaft is too long and rotates at high speed, it is easy to cause slight shaking of the output shaft due to factors such as centrifugal force. Utility Model Content

[0006] The purpose of the present utility model is to provide a paint sprayer, which solves the problem that although the existing paint sprayers use components such as filters to filter out impurities from raw materials, the filter screen may be blocked after long-term use due to the influence of factors such as the adhesion characteristics of impurities; and solves the problem that the existing paint sprayers simply use the coordinated use of components such as motors and stirring blades to complete the stirring and mixing of paint, and the adhesion characteristics of the paint may easily cause the paint to adhere to the inner wall of the stirring tank and cause waste, and the excessively long motor output shaft may easily cause slight shaking of the output shaft when rotating at high speed due to factors such as centrifugal force.
