Conveying belt type surface pressure film-covering and coating process and device

Abstract

The invention relates to a conveying belt type surface pressure film-covering and coating process and device and belongs to the technical field of object surface coating. According to the technical scheme, a conveying belt is arranged on a front roller (4) and a rear roller (5); a coating solidifying device (9) is arranged in the position, between the front roller (4) and the rear roller (5), in an annular belt body of the conveying belt or arranged behind the conveying belt; a film (2) is arranged on a film encircling frame (21) and passes through the lower surface of the conveying belt in anencircling mode, and the film and the conveying belt (3) operate synchronously; the front roller (4) serves as a film-covering and coating roller and used for conducting surface pressure film-covering and coating, the rear roller (5) uncovers the film synchronously, or a film uncovering roller (8) is additionally arranged to uncover the film; and the film encircling frame (21) and the conveying belt are arranged above a coating object bearing device (11) in a matched mode. Through the conveying belt type surface pressure film-covering and coating process and device, cheap soft films, thin films, and fluffy mould films with various grains and patterns can be well used normally, continuous new film supplying, automatic film-covering and coating, automatic solidifying, automatic film uncovering and continuous used film recovery are achieved, and rapid and efficient full-automatic operation is achieved.

Description

technical field [0001] The invention relates to a conveyor belt type surface pressure film coating process and device, belonging to the technical field of object surface coating. Background technique [0002] The characteristics of film-coating are that the application of film for film-coating, forced leveling, mirror finish, and more and more applications. The processing cost competition in the film coating processing market is fierce. There are more and more demands for film coating processing of various patterns and colors, and the requirements for film coating effects are getting higher and higher. Any flaws on the coating surface are unqualified; and for the cost of film coating processing, various patterns, patterns, and coating effects, the film for film coating and how to use it play a key role. Film coating technology. There are many types of membranes, the material properties are very different, and the price gap is large. The coating industry requires film coat...

Problems solved by technology

[0003]However, the existing roller-type film coating equipment, such as pressure-roller-type film-coating finish machine and other pressure-roller-type film coating equipment and The applicant applied for an invention patent on March 13, 2009: a method and device for coating and curing ultraviolet light-curable coatings, the patent number is: 200910119419.8; both use a cylindrical pressure roller as the film coating device, Only use anti-scratch, hard material, thick film or film with very thick film body. Only after the film is coated with the whole stile and the film is not deformed and the film is removed, can the coating be qualified and excellent with the best effect, which is competitive; the problem is Hard material film or thick body film is expensive, and the cost of coating with film is too high

However, when coating with cheap soft material film, thin body film and fluffy mold film with various patterns and patterns, many defects will appear: wrinkles, micro-concave-convex phenomena, micro-bulges, wrinkled edges of the coating, and air formation Bubbles, air bubbles and other defects, resulting in the loss of residual coating waste

When the length direction of the coil is stretched, there will always be transverse corrugation. In addition, when the equipment is running, the film will also shake, and the film will easily wrinkle during coating; along the length direction of the film, the edges of the coated object will easily Wrinkles, air bubbles and air bubbles appear on the edge of the wings, resulting in waste coating products. The longer the stretched length and the larger the area, the more serious the above defects are, which are the shortcomings and drawbacks of the existing pressure roller type film coating equipment.

[0007]In the existing pressure roller type film coating equipment, the apex of the arc under the pressure roller is simply a line of pressure coating, and the film coating pressure line is narrow and thin ; It can only achieve the pressure coating function of adding curing agent or mixing multiple materials in the coating; it can not simultaneously achieve the function of accelerating the curing of the coating by heating; the existing pressure roller type film coating equipment, in Many defects caused by the disadvantages of the coating mechanism can no longer meet the requirements of the film coating processing industry: cheap soft material films, thin body films and fluffy mold films with various patterns and patterns can be used to improve the coating effect. Labor-saving, high-efficiency, fully automatic operation, the needs of development forms
