Description

Technical Field

[0001] The invention relates to printing equipment, in particular to an automatic glazing device applied to a glazing machine. Background Art

[0002] At present, fully automatic glazing machines and laminating machines are special printing equipment used for glazing and laminating paper and board materials, which respectively realize the paper glazing and paper-plastic composite functions, and improve the quality and grade of paper. Its automatic glazing device includes an upper wall panel and a rubber roller, a lower wall panel and a steel roller. The rubber roller is adjacent to the metering roller, and the glazing oil is applied between the rubber roller and the metering roller. When not working, the rubber roller and the metering roller must be separated, which requires frequent manual adjustment, which is cumbersome and has low work efficiency. In addition, the amount of oil (i.e., the amount of glue) is difficult to control accurately, resulting in the inability to uniformly control the amount of dry oil and water (i.e., dry glue) on the same specification of paper. In addition, the dry oil and water (i.e., dry glue) on the back of the paper will not be scraped off cleanly, affecting the quality of paper glazing. Summary of the invention

[0003] The object of the present invention is to overcome the above technical deficiencies and provide a paper clean automatic glazing device which can quickly adjust and effectively control the amount of oil applied.

[0004] The object of the present invention is achieved through the following technical scheme: a paper cleaning automatic glazing device, comprising an upper wall panel and a rubber roller, a lower wall panel and a steel roller, the rubber roller is connected to a conveying power source through a conveying intermediate transmission assembly, a lower glue disc is installed on the lower wall panel and under the steel roller, an anilox roller is installed on the upper wall panel and at the side of the rubber roller through an anilox roller fixing seat, the anilox roller fixing seat is connected to a propulsion power source, an upper scraper assembly is installed on the upper wall panel and at the side of the anilox roller, and an upper glue disc is installed on the upper wall panel and under the anilox roller.

[0005] The anilox roller has a plurality of "well"-shaped combinations. The anilox roller is connected to a glue control power source through a glue intermediate transmission assembly to achieve separate control of the anilox roller. A splash shield is installed on the roller shaft of the anilox roller and above the glue disc.

[0006] The anilox roller fixing seat is mounted on the upper wall plate through a linear guide rail. A lower scraper assembly is mounted on the lower wall plate and at the side of the steel roller.

[0007] After adopting the structure of the present invention, the surface of the anilox roller has an anilox pattern (in a "well" shape combination arrangement), and the glazing oil will remain in the inner area of ​​the anilox pattern. The upper scraper assembly scrapes away the glazing oil on the surface of the anilox roller, and the glazing oil inside the anilox pattern will only be taken away by the rubber roller and transferred to the paper for glazing. Therefore, the glazing oil weight of each paper of the same specification can be accurately controlled to be the same. The lower rubber disc is filled with clean water to keep the back of the paper clean after glazing. The bonding or separation between the anilox roller and the rubber roller is automatically controlled by the propulsion power source. It is easy to operate, has a high degree of automation, high work efficiency, and improves the glazing quality of the paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further described in detail below through the accompanying drawings and embodiments.

[0013] Reference Figures 1 to 4 It can be known that the paper clean automatic glazing device applied to the glazing machine of the present invention comprises an upper wall panel 2 and a rubber roller 5, a lower wall panel 1 and a steel roller 17, the rubber roller 5 is connected to a conveying power source 8 (a conveying motor) through a conveying intermediate transmission assembly 9, a lower glue disc 20 is installed on the lower wall panel 1 and under the steel roller 17, an anilox roller 4 is installed on the upper wall panel 2 and at the side of the rubber roller 5 through an anilox roller fixing seat 12, the anilox roller fixing seat 12 is connected to a propulsion power source 10 (a propulsion cylinder, which is installed on the upper wall panel 2 through a propulsion power source seat 11), an upper scraper assembly 3 (including an upper scraper, an upper scraper seat, etc., the upper scraper seat is installed on the upper wall panel) is installed on the upper wall panel 2 and at the side of the anilox roller 4, and an upper glue disc 7 is installed on the upper wall panel 2 and under the anilox roller 4 (through an upper glue disc fixing frame 18). As shown in FIG. Figure 2 As shown, a steel roller sprocket 16 is installed on the roller shaft of the steel roller 17, and the steel roller sprocket 16 is connected to the conveying roller sprocket 13 through a chain 15. The conveying roller sprocket 13 is installed on the roller shaft of the conveying roller 14. The steel roller sprocket 16 is connected to the conveying intermediate transmission component 9 to realize the synchronous conveying of paper.

[0014] The mesh patterns on the anilox roller 4 are in the form of a plurality of "well"-shaped combinations, which is conducive to concentrating the varnish in the center of the "well"-shaped area. A splash shield 6 (such as Figure 1 As shown in the figure, one on each side), it can effectively prevent the varnish from splashing. Figure 3 As shown, the anilox roller 4 is connected to the gluing control power source 22 (gluing control motor) through the gluing intermediate transmission assembly 23 to achieve independent control of the anilox roller. The anilox roller fixing seat 12 is mounted on the upper wall plate 2 through a linear guide rail 21, which is conducive to the linear propulsion of the anilox roller fixing seat and the anilox roller and the effective contact with the rubber roller. A lower scraper assembly 19 is mounted on the lower wall plate 1 and on the side of the steel roller 17 to scrape off the excess varnish on the steel roller again.

[0015] The conveying power source 8 drives the steel roller sprocket 16 and the rubber roller 5 on the steel roller 17 respectively through the conveying intermediate transmission assembly 9, and the steel roller sprocket 16 drives the conveying roller 14 to rotate through the chain 15 to realize the paper conveying action. The gluing control power source 22 drives the anilox roller 4 to rotate independently through the gluing intermediate transmission assembly 23. The working principle of the present invention is: the bottom of the anilox roller 4 is adhered with the glazing oil in the gluing plate 7, and the excess glazing oil is scraped away by the upper scraper assembly 3 through the rotation of the anilox roller. The propulsion power source 10 works to fit the anilox roller fixing seat 12 and the anilox roller 4 and the rubber roller 5, and the glazing oil is transferred to the rubber roller 5, and then transferred to the paper between the rubber roller 5 and the steel roller 17 through the pressing of the upper and lower wall panels. The surface texture structure of the anilox roller 4 is arranged in many "well"-shaped combinations. The varnish will remain in the inner area of ​​the "well" shape. The upper scraper assembly 3 will scrape away the varnish on the surface of the anilox roller, and the varnish inside the "well" shape will only be picked up by the rubber roller 5 and transferred to the paper.

[0016] Different paper products require the replacement of anilox rollers with different mesh counts (i.e., the density of the "well" shape combination) according to the different thickness of the varnish required. This improvement is aimed at high-standard customers who have a large amount of paper and want to control the same specifications and the same gram weight of varnish on each sheet of paper. The original manually adjusted metering roller simply cannot meet the requirement of the same gram weight of varnish on each sheet.

[0017] The reason for using the glue control power source 22 and the conveying power source 8 separately is to control the rotation speed of the anilox roller 4 and the rubber roller 5 respectively, so that no "horizontal bar" phenomenon will appear on the finished paper. The steel roller 17 is immersed in the lower glue tray 20, which is filled with clean water. There is a gap between the front paper and the back paper, and the glazing oil will stay in this gap. The glazing oil in this gap is transferred to the clean water of the lower glue tray through the rotation of the steel roller, and then the steel roller 17 is scraped clean by the lower scraper assembly 19. Therefore, the back of the paper is clean and will not be contaminated (no dry glue).
