Upper feeding and covering device for color covered household appliance product paint covering and covering method thereof

Abstract

The invention relates to an upper feeding and covering device for color covered household appliance product paint covering and a covering method thereof, and belongs to the technical field of cold rolling deep processing equipment of metallurgical industry. According to the technical scheme, the device comprises a supporting roll (1), a covering roll (2) and a pickup roll (3), wherein the coveringroll (2) is located between the supporting roll (1) and the pickup roll (3), the upper feeding and covering device for color covered household appliance product paint covering is characterized in that a metering roll (6) is arranged above the pickup roll (3), the metering roll (6) and the pickup roll (3) are arranged in parallel, a gap is formed between the metering roll (6) and the pickup roll (3), a feeding disk (5) is arranged over the metering roll (6), and a discharging opening which faces the metering roll (6) is formed in the feeding disk (5). The upper feeding and covering device forcolor covered household appliance product paint covering has the beneficial effect that the purpose of paint leveling evenness is achieved fundamentally, and the defects of local bright tracks or short strips or the like are overcome, so that the quantity of waste products generated due to the defects is greatly reduced, and the evenness and the exquisiteness of paint on product surfaces are improved.

Description

technical field [0001] The invention relates to a material feeding coating device and coating method for the coating of color-coated home appliances, and belongs to the technical field of cold-rolling deep-processing equipment in the metallurgical industry. Background technique [0002] The finish coater is an important equipment in the coating process, and the method of coating the top coat is double-roller or three-roller coating with bottom dipping material. [0003] Refer to attached figure 1 , The finish coating machine includes a support roller, a coating roller, a dipping roller and a material tray, the coating roller is located between the support roller and the dipping roller, and there is a tray below the dipping roller, and the depth of the tray is about 10cm. During the production process, the paint in the lower material tray is brought to the coating roller through the rotation of the dipping roller, and then the coating roller evenly coats the paint on the ste...

AI Technical Summary

Problems solved by technology

Since the depth of the material tray is about 10cm, after a period of production, due to the slow flow of the paint at the bottom of the material tray, the paint is left to settle, and the various components in the paint are layered. Defects such as short strips and bright lines appear on the surface of the belt, especially when producing high-end products such as home appliances, short strips and bright lines are more likely to appear, which affects product quality

After bright roads and short strips appear, it is forced to stop and change the paint, resulting in excessive waste of finished products and increasing the amount of waste products. According to statistics, each time the paint is changed, 1.2 tons of waste products will be generated, affecting the production rhythm for 30 minutes.

[0004] At present, in order to solve the above problems, a baffle is usually added in front of the dipping roller. Although it can effectively delay the layering of the coating, as time accumulates, short and bright lines will appear at both ends of the strip. defect
