Water-based paint uniform spraying device and method for color steel plate spraying

Abstract

The invention discloses a water-based paint uniform spraying device and method for color steel plate spraying, and relates to the technical field of color steel plate production. The water-based paint uniform spraying device comprises a shell, wherein a motor is installed on the inner wall of the bottom end of the shell through a pipeline, the output end of the motor is fixedly sleeved with an output shaft, and the outer wall of the output shaft is in transmission connection with a rotating shaft through a belt; the outer wall of top of the rotating shaft is fixedly sleeved with an incomplete gear, and the outer side of the incomplete gear is engaged with annular racks. According to the water-based paint uniform spraying device and method, a threaded rod drives a mounting block to move rightwards, the mounting block drives a spray head to move rightwards through an electric push rod, automatic spraying work is conducted on the X axis of a color steel plate, and the whole color steel plate surface can be sprayed, so that the function of intermittently moving the color steel plate while spraying is achieved; and a nozzle moving device does not need to be additionally arranged, so that energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of color steel plate production, in particular to a device and method for uniformly spraying water-based paint for spraying color steel plate. Background technique [0002] Color steel plate refers to color coated steel plate, which is a kind of steel plate with organic coating. Color steel plate is divided into veneer, color steel composite plate, floor bearing plate and so on. It is widely used in the walls and roofs of large public buildings, public workshops, prefabricated houses, and integrated houses. It needs to be sprayed in the production of color steel plates. [0003] However, at present, when painting the color steel plate, it is usually sprayed manually, the spraying effect is poor, the spraying is uneven, and the work efficiency is low. In addition, the paint cannot be filtered during the spraying process, resulting in unevenness on the color steel plate after spraying. Or adopt mechanical de...

[0003] However, at present, when painting the color steel plate, it is usually sprayed manually, the spraying effect is poor, the spraying is uneven, and the work efficiency is low. In addition, the paint cannot be filtered during the spraying process, resulting in unevenness on the color steel plate after spraying. Or adopt mechanical device to carry out spraying, such as publication number CN211587146U, disclose a kind of spraying device for color steel plate that can filter coating, comprise support and feed box, described support is provided with fixed frame and housing, and fixed frame It is arranged on the outer side of the housing, and the inner top of the housing is provided with a hot fan, the inner top of the fixed frame is provided with a hydraulic telescopic rod, and the lower end of the hydraulic telescopic rod is provided with a mounting plate, and the lower end of the mounting plate is provided with There is a blowing fan and a cleaning mechanism, the supply box is arranged on the upper surface of the fixed frame, and a booster pump is arranged on the right side of the supply box, and the end of the booster pump away from the supply box is connected to the spray pipe, and The end of the nozzle away from the booster pump passes through the upper end surface of the fixing frame and is arranged above the conveyor belt

However, the spraying of this device is not uniform enough, the spraying effect is not ideal, and it is impossible to spray the color steel plate in azimuth. The spray head needs different driving devices to drive the movement of the X-axis and Y-axis respectively. Not only the structure is complicated, but also two sets of driving equipment It consumes a lot of energy and does not meet the theme of energy conservation and environmental protection today
