Spraying device for heating and ventilation pipe fitting production treatment

Abstract

The invention relates to the technical field of heating conveying, in particular to a spraying device for heating and ventilation pipe fitting production treatment. The device comprises a bottom plateand two fixing frames, wherein the two fixing frames are slidably connected to the two ends of the bottom plate correspondingly, and a first inner column and a second inner column are arranged between the two fixing frames correspondingly. According to the spraying device, a second motor rotates to drive a gear to rotate, the gear meshes with a rack, an outer cylinder slides towards one side of the second inner column, when a pipeline passes through a paint spraying wheel, the paint spraying wheel is started, paint is completely smeared on the outer side wall of the pipeline, and a first motor drives the first inner column and the second inner column to rotate, so that the pipeline can circumferentially rotate, when the pipeline passes through a coating plate, a sponge roller of the coating plate slides to be extruded and attached to the side wall of the pipeline, and the pipeline can rotate relative to the coating plate, so that the paint on the pipeline is completely and uniformly distributed, the quality of pipeline spraying is improved, and the paint is more uniformly smeared.

Description

technical field [0001] The invention relates to the technical field of warm air transportation, in particular to a spraying device for the production and treatment of heating and ventilation pipe fittings. Background technique [0002] Heating is divided into water heating and gas heating. Usually, what we call a radiator refers to water heating, which is to use a wall-hung boiler or a boiler to heat circulating water, and then connect it to the radiator through a pipe, and finally output the appropriate temperature through the radiator to form an indoor temperature difference. , and finally perform a thermal cycle to make the entire indoor temperature rise evenly. The air heating is to heat the air. As soon as the cold air comes in, it is heated by the radiator to become hot air. The hot air rises to form convection with the cold air in the room, and the cold air circulates to the heating area to be heated to become hot air. [0003] Due to the large components of the HVAC...

AI Technical Summary

Problems solved by technology

[0003] Due to the large components of the HVAC pipeline, the workload of manual spraying is relatively large. When using automatic spraying machines, because the pipeline is a circular structure, it is difficult to spray it evenly on the side wall of the pipeline, and due to gravity, the paint is also It will slide down and concentrate at the bottom of the pipe, resulting in uneven coating on the side wall of the pipe, which will cause unsightly appearance and affect the use effect
