Coating spraying machine and continuous spraying method

Abstract

The invention relates to the technical field of coating spraying machines, and discloses a coating spraying machine. The coating spraying machine comprises a machine body, a first reciprocating motioncover, a second reciprocating motion cover and a motor box; the motor box is fixedly mounted on the back surface of the machine body; a driving motor is fixedly mounted in the motor box; and a secondrotating shaft is rotationally connected to the front end of the driving motor. According to the coating spraying machine, the driving motor is started to drive a first bevel wheel to rotate so as todrive the second rotating shaft to rotate, the second rotating shaft enables sector gears fixedly mounted at the left end and the right end of the second rotating shaft to be engaged with racks in the corresponding reciprocating motion covers, and then the reciprocating motion covers are driven to do reciprocating motion; when the first reciprocating motion cover descends, the second reciprocating motion cover ascends, a servo motor does not need to be arranged, the servo motor is controlled to alternately rotate forwards and backwards, and therefore, the working efficiency is greatly enhanced; and moreover, an output shaft of the driving motor can continuously rotate in the same direction, so that coating spraying operation can be continuously conducted.

Description

technical field [0001] The invention relates to the technical field of paint spraying machines, in particular to a paint spraying machine and a continuous spraying method. Background technique [0002] Paint spraying machine is a special painting equipment using spraying technology. The principle is to control the air flow to instantly push the air distribution reversing device to change direction, so that the piston of the air motor makes a stable and continuous reciprocating movement, pressurizes the inhaled paint, and passes through the high pressure. The hose transports the paint to the spray gun of the sprayer, and the spray gun atomizes the paint instantly and releases it to the surface of the object to be coated. The spraying machine is mainly composed of a feeding device, a spray gun, and an atomization source. Suitable for leather handbags, gift packaging, furniture, footwear, automobile manufacturing and other industries. [0003] Existing paint spraying machines...

AI Technical Summary

Problems solved by technology

[0003] Existing paint spraying machines basically use a servo motor to drive the piston to move. During the spraying process, the servo motor needs to be controlled to alternate between positive and negative rotations. It also needs to be decelerated in the process of accelerating the rotation. The continuous effect of spraying is low, which affects work efficiency. At the same time, long-term motor work will generate high temperature, which needs to be dissipated to maintain the stability of spraying work
