Novel aluminum veneer pre-roll-coating production line and process technology

Abstract

The invention provides a novel aluminum veneer pre-roll-coating production line and a process technology and relates to the technical field of machinery. A series of key technologies including alkaline washing, cleaning, passivation, coating, printing and drying are adopted, and a front conveying belt, an alkaline washing machine, a cleaning machine, a chromate-free passivation device, a baking oven, a precise single-roller priming paint coating machine, a far infrared baking oven, a three-roller coating machine, a far infrared device, a multi-color stereoscopic printing machine, a far infrared machine, a precise single-roller priming paint coating machine, a curing baking oven and a rear conveying belt are sequentially placed to form the novel aluminum veneer pre-roll-coating production line. The process technology is that an aluminum veneer pre-roll-coating product is manufactured through feeding, alkaline washing, cleaning, passivation, air-drying, priming paint roll-coating, far-infrared heating and curing, finishing coat roll-coating, secondary far-infrared heating and curing, multi-color printing, third far-infrared heating and curing, varnish roll-coating, heating and drying and film coating and off-line operation. The novel aluminum veneer pre-roll-coating production line and the process technology are used for aluminum veneer roll-coating and are novel in concept, reasonable in design, simple and ingenious in structure, stable and reliable in effect and low in cost and facilitating manufacture, usage and popularization.

Description

technical field [0001] The invention discloses a novel production line and technology for pre-roll coating of aluminum veneers, and relates to the field of mechanical technology. Background technique [0002] At present, as a new type of building decoration material, aluminum veneer has incomparable advantages over other traditional curtain wall decoration materials—it is light and thin, easy to install, diverse in color, recyclable, and meets the extensive needs of the building decoration market. As a new type of building decoration material - finished aluminum veneer - there are two production methods: one is the traditional manual operation method, which hardly involves mechanical equipment; the other is the pre-roller coating large-scale production line. As far as the traditional manual operation method is concerned—it is formed by aluminum sheet and sprayed with liquid or powder paint multiple times—its shortcomings, defects and disadvantages are high manufacturing cost...

AI Technical Summary

Problems solved by technology

However, although the pre-roller coating plate produced by the large-scale pre-roller coating production line has been used as the main material for building exterior wall decoration, there are still many problems in its wide application.

Such as: (1), the cost of equipment is high, there are many domestic curtain wall enterprises, small scale, mixed fish and dragons, and there is no lack of workshop production. For a large pre-roller coating production line ranging from tens of millions to billions of yuan and the strict technology of the production line As far as the supporting requirements are concerned, it is obviously not yet possible to apply this technology; (2) Since the selected substrate is in roll form, it can only be limited to the production of 2mm-3mm thick roller-coated aluminum veneers, which cannot fully satisfy the market Demand; (3), aluminum roll coating production capacity is huge and the variety is single, which often leads to excessive inventory backlog; (4), large-scale pre-roll coating production lines are continuously produced, and it is very difficult to change color patterns

(5), unable to play the best state of the large-scale pre-roller coating production line

All these can show that the deficiencies, defects and drawbacks of the large-scale pre-roller coating production line are insurmountable
