Abstract

The invention discloses spraying equipment. The spraying equipment comprises a sealed coating box which is used for containing coating and a spraying gun for spraying the coating, and further comprises a sealed pressure box and a variable air pump; the coating box is provided with an air pump connector and a material supplying hole; the pressure box is provided with a feeding hole and a discharging hole; the variable air pump is communicated with an air pump connector; the feeding hole is communicated with the material supplying hole; the discharging hole is communicated with the spraying gun; the variable air pump can drive the coating to enter the pressure box 3 and the coating is sprayed out through the spraying gun 2; the spraying equipment further comprises a controller and a pressure sensor arranged in the pressure box; the controller can be used for controlling starting and stopping and a rotary speed of the variable air pump according to pressure detected by the pressure sensor. The controller is used for controlling the starting and stopping and the rotary speed of the variable air pump according to the real-time pressure, and online adjustment of a spraying flow of the spraying equipment is realized in real time; the responding speed is relatively rapid; meanwhile, the pressure is detected in real time so that working pressure is stable and the spraying is more uniform. Gas-liquid control separation is realized, explosion is prevented and the safety is improved.

Description

technical field [0001] The invention relates to the field of spraying, in particular to a spraying equipment. Background technique [0002] Spraying equipment is widely used in the production process of ceramics, automobiles and other products. Due to the requirements of the spraying process, the spraying thickness requirements of each part of the product to be sprayed are different. For example, the spraying thickness of the side and front of the car body is greater than that of the roof. At the same time, spraying requires uniform spraying locally, which requires the spraying equipment to have the ability to adjust the flow rate and stabilize the pressure. [0003] At present, most equipment adopts manual flow adjustment, that is, manually adjusts the size of the valve before spraying to control the flow, and then sets a maximum pressure value for the air compressor, and stops working when it reaches the preset pressure value. Start working again when the pressure drops....
