Embodiment Construction

[0018] see Figure 1 to Figure 2 , The air-floating guide roller of the present invention has three rows of "horn"-shaped small air holes 4 evenly distributed on one side of the roller surface, the roller body is hollow, one end is sealed 3, and the other end is not sealed 2.

[0019] see image 3 , the present invention is mainly implemented through the following schemes:

[0020] The vortex air pump fan 5 operates to generate air pressure, and the gas is continuously fed into the roller from the unsealed end 2 of the air-floating guide roller 1 through the rubber tubes 6 and 7, and then ejected from the "horn"-shaped small air hole 4, forming a side surface. The arc-shaped air wall supports the film, so that the film does not touch the surface of the guide roller evenly during travel, and is stable and free of resistance, thereby avoiding abrasion and scratching the printing surface of the film.

[0021] According to the normal printing process, after the front printing is...

Abstract

The invention relates to an air-float type film turning device used for once double-side intaglio printing of a film, which comprises five rolling guide rollers, two air-float type guide rollers, a vortex pump fan and a rubber pipe, wherein the two air-float type guide rollers are fixedly mounted in a vertical crossing form at a 45-degree angle. According to a normal printing process, the air-float type film turning device is used for printing one side of the film and then finishing an operation of turning from a positive side to a negative side (namely, realizing 180-degree turning during a film proceeding process) with the help of the running between the five rolling guide rollers and two air-float type guide rollers, and lastly the negative side printing is directly carried out for once finishing a whole printing process. The air-float type film turning device is mounted on a slide rail and can flexibly adjust the quantity of printing colors of the positive and negative sides according to a practical printing requirement (for example, printing in combination forms, such as eight positive colors, seven positive colors and one negative color, six positive colors and two negative colors, five positive colors and three negative colors, four positive colors and four negative colors, and the like). The air-float type film turning device provided by the invention has the advantages of greatly promoted quality of a printed product, high speed, time-saving property, labor-saving property, electricity-saving property, reduced material loss, energy-saving property, material-saving property, high efficiency, high printing accuracy of negative side, stable quality and the like, and the air-float type film turning device is free from abrading and scratching printing sides.

Description

technical field [0001] The invention relates to a film reversing device, in particular to an air-floating film reversing device used for one-pass double-sided gravure printing of films. Background technique [0002] With the continuous improvement of the quality requirements for the outer packaging of food, medicine and other products, and the rapid development of composite flexible packaging, higher and higher requirements are put forward for plastic film gravure printing technology. The quality of packaging printing directly affects the dominant position in the product market competition, and affects the benefits and development prospects of enterprises. Plastic film gravure printing is a highly specialized technology involving machinery, materials, chemical inks, heating and drying, etc. There are still many problems to be solved in actual use. When the current technology requires double-sided printing of the film, only one color can be printed on the reverse side (such ...
