Description

Technical Field

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

[0002] A sprayer can use high-pressure gas or liquid to spray paint onto the surface of an object to obtain a more perfect coverage effect. When using a conventional high-pressure sprayer, after the fixed frame is moved to the appropriate position with the help of rollers, the pressure pump on the top of the fixed frame is connected to the power supply, and the paint is poured into the storage barrel on the top of the pressure pump. The pressure pump pressurizes the paint and sprays it out from the spray gun at one end of the pressure pump.

[0003] According to the description of a spray machine disclosed on the patent website (authorization announcement number: CN 218438047 U), "The utility model belongs to the field of spray machines, and particularly relates to a spray machine, including a frame, on which a pneumatic pump and a hydraulic pump are arranged, and the pneumatic pump is connected to a gas distribution reversing valve, and the frame is provided with a support plate for supporting the pneumatic pump, and both sides of the support plate extend downward to form a support plate connected to the frame, and a mounting plate is arranged under the support plate, and the mounting plate is arranged between the support plates, and the gas distribution reversing valve is detachably arranged on the mounting plate. The purpose of the utility model is to provide a spray machine that is easy to disassemble and maintain."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model uses compressed air to drive the pneumatic pump to work, and then drives the cylinder piston rod and drives the paint cylinder piston rod to do up and down reciprocating motion to achieve spraying. However, the paint on the inner wall of the storage barrel is mostly under normal pressure, and because some paints are relatively thick, the paint flows out slowly when the sprayer is spraying. When the sprayer increases the spray flow rate, the paint in the storage barrel is prone to a slow supply speed, which causes the spray flow rate to be affected. Therefore, it is necessary to improve a sprayer with adjustable spray flow to solve the above problems. Utility Model Content
