Construction hoist standard knot coating production line and coating process

Abstract

The invention discloses a construction hoist standard knot coating production line. The construction hoist standard knot coating production line comprises a workpiece feeding area, a workpiece discharging area, a conveying track, a shot blasting machine, a shot cleaning chamber, a spraying room, a curing room and a cooling station, a conveying track sequentially penetrates through the workpiece feeding area, the shot blasting machine, the shot cleaning chamber, the spraying room, the curing room, the cooling station and the workpiece discharging area to form a continuous operation production line, a plurality of shot blasting devices with opposite openings are arranged on the inner wall of the shot blasting chamber in the shot blasting machine, the shot blasting chamber communicates with the shot cleaning chamber, a plurality of shot cleaning guns are arranged in the shot cleaning chamber, a recovery device inclining from the shot cleaning chamber to the shot blasting machine is arranged at the bottom of the shot cleaning chamber, so that cleaned and fallen balls fall back into the shot blasting machine, the top of the shot blasting chamber and the top of the shot cleaning chamber both communicate with a filter cartridge dust remover, a plurality of movable spray guns are arranged on two sides of the conveying track in the spraying room, and a heating system is arranged in the curing room and used for heating passing standard knots. According to a semi-automatic production line mode, less labor is needed, and the problem of high labor cost is solved.

Description

technical field [0001] The invention relates to the technical field of coating protection for construction elevators, and specifically belongs to a coating production line and a coating process for standard sections of construction elevators. Background technique [0002] As the running guide rail of the construction elevator, the construction elevator standard section is an important structural part of the construction elevator. Due to its fast running speed and harsh operating conditions, in the production process of the construction elevator standard section, in order to ensure its corrosion resistance and aesthetic requirements, Coating protection for the standard section of the construction hoist is an essential process. The coating process method of the existing standard section of the construction elevator is: pretreatment (manual grinding) - manual spraying - leveling - natural air drying, pretreatment is the primary process of the coating process, good pretreatment ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of low efficiency, uneven quality, serious pollution, long cycle and high labor cost in the existing painting technology, and under the premise of minimizing the influence of traditional artificial random errors, through semi-automatic painting The production line and the complete new process method of upper part → shot blasting → shot blasting → powder spraying → powder solidification → cooling → inspection of the next part, thus forming a systematic and pipelined batch coating production process for the standard section of construction elevators, and then realizing Production goals of cost reduction and efficiency increase, production and quality improvement, environmental protection and energy saving
