A spin-coating process for the bottom cover of a steel drum

Abstract

The invention discloses a spin-coating process for the bottom cover of a steel drum. The process is specifically as follows: the first step is to wash the bottom cover, and the bottom cover to be processed is cleaned by a bottom cover washing machine; The heating system heats and dries the cleaned bottom cover; the third step, purging, dust blows the heated bottom cover, and the purging process is completed by an air knife; the fourth step, spin coating, passes through a high-speed electromagnetic clutch Control the spin coating of the electromagnetic spin coating equipment; the fifth step is heating and drying, and drying the spin-coated bottom cover through a drying spiral tower; the sixth step is packaging the finished product, and the present invention proposes a steel drum bottom cover Spin coating process, energy saving and environmental protection, adopts self-developed cover washing machine, electromagnetic heating equipment and high-speed electromagnetic clutch to control spin coating, with high degree of automation, improving production efficiency and product quality.

Description

technical field [0001] The invention relates to a coating process, in particular to a spin coating process for the bottom cover of a steel drum, and belongs to the technical field of coating processes. Background technique [0002] The existing technology of iron drum processing is to uniformly spray the steel drums after they are made into finished products; there are single-station (single-color) and double-station (two-color) spraying, which has many shortcomings, because the spraying method is adopted, there is dust Pollution, organic solvents volatilize and produce harmful gases, and some environmental problems such as water pollution have been caused by water-based paints; because of the use of station rotation control, it will cause a lot of noise. Because of spraying the entire barrel body including the bottom cover, it will cause a lot of waste. At the same time , because there are 5 spray guns for spraying the bottom cover, the direction is upward and downward, a l...

Problems solved by technology

[0002] The existing technology of iron drum processing is to uniformly spray the steel drums after they are made into finished products; there are single-station (single-color) and double-station (two-color) spraying, which has many shortcomings, because the spraying method is adopted, there is dust Pollution, organic solvents volatilize and produce harmful gases, and some environmental problems such as water pollution have been caused by water-based paints; because of the use of station rotation control, it will cause a lot of noise. Because of spraying the entire barrel body including the bottom cover, it will cause a lot of waste. At the same time , because there are 5 spray guns for spraying the bottom cover, the direction is upward and downward, a lot of spray falls on the station, so that a lot of paint remains in the spraying work, which makes the cleaning work very difficult, making the spraying room dirty, messy and poor, resulting in solid state Waste pollution; in the traditional spraying process, the anti-paint cover must be installed before spraying, and the closure must be replaced after spraying. There are many processes in the barrel making process, and the cost of barrel making is high; in the traditional spraying process, there are many links in the product quality, and one link appears If there is a problem, there will be unqualified products in batches. Especially when spraying the bottom of the barrel, it can only be sprayed blindly. The operator needs to check frequently, which is harmful to the health of the operator. From the perspective of the quality of the entire spraying process, the coating is uneven and sags. , the size of the skin of the barrel, the sun, defects occur from time to time
