Problems solved by technology

Due to the existence of multiple processes, the turnover requirements between each process must be equipped with venues, fixtures, transport vehicles, personnel, etc., and the cost is too high
At the same time, because the workpiece is transported and turned around in different processes, it will cause the workpiece to be scrapped, fall off, etc., resulting in a decrease in yield and an increase in cost.

Abstract

The invention relates to plastic coating production equipment and a production method thereof. The production equipment comprises a conveying base and a workpiece rest, wherein a priming paint coating and curing chamber, a vacuum coating chamber and a finishing paint coating and curing chamber are arranged on the conveying base in order; the workpiece rest is used for allowing a workpiece to be placed thereon and is arranged on the conveying base; under the driving of the conveying base, the workpiece rest passes through the priming paint coating and curing chamber, the vacuum coating chamber and the finishing paint coating and curing chamber in order. The production method is processed in the production equipment. The plastic coating film production equipment builds full-automatic combination production line of multiple processes of UV priming paint curing, coating and UV finishing paint curing, and provides the multifunctional coating production line of which the production cost is reduced. In addition, as the workpiece rest moves on the conveying base, the plastic coating production equipment can be shared between the coating production line and evaporation coating equipment. The plastic coating production equipment has the advantage of simple structure, and is more convenient to use and easy to operate, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a plastic coating production equipment and a production method. Background technique [0002] Plastic has the characteristics of light weight, excellent performance, easy molding, and easy processing. It has a wide range of applications and is an indispensable material for daily life and various sectors of the national economy. Vacuum coating technology is applied to plastic surface, that is, vacuum coating decoration process, which can overcome the shortcomings of plastic surface such as lack of metallic luster, low surface hardness, and easy aging, and can further expand the use of plastics. In recent years, consumers have higher and higher requirements for the appearance of such products. While obtaining a metallic texture on the decorative surface of vacuum coating, they also propose improvements in the surface optical properties, surface wear resistanc...
