Description

Technical Field

[0001] This utility model relates to the field of printing press coating, and in particular to a coating device used in a special printing press. Background Art

[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, plastics, and leather to reproduce the content of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special inks.

[0003] Currently, Chinese patent CN209997862U discloses a gluing device for a special printing machine, including a support bar. Threaded rods are threadedly connected to corresponding positions on the surface of the support bar, with the top of the threaded rods extending to the top of the support bar. A gluing table is slidably connected between corresponding sides of a support plate, with the bottom of the gluing table rotatably connected to the top of the threaded rods. Dovetail sliders are slidably connected to corresponding sides of the support plate near its top. However, the above patent requires manual adjustment when adjusting the gluing for printed materials of different thicknesses, lacking an automatic gluing height adjustment structure, thus reducing the flexibility during construction. Therefore, we propose a gluing device for a special printing machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a gluing device for use in special printing machines to solve the problems mentioned in the background art.

[0007] In a further embodiment, the bottom end of the telescopic hose passes through the coating cover and extends above the coating cover, and the telescopic hose is located above the coating roller.

[0008] In a further embodiment, two bearings are fixedly embedded in the inner wall of the coating cover, and the outer surfaces of the left and right ends of the coating roller are respectively fixedly connected to the inner rings of the two bearings.

[0009] In a further embodiment, a connecting plate is fixedly connected to the back of the adhesive coating cover, and a brush plate is fixedly connected to the bottom surface of the connecting plate.

[0010] In a further embodiment, the inner sidewall of the support cover has two limiting holes, and the outer surface of the adhesive cover is fixedly connected to two limiting blocks, with the ends of the two limiting blocks extending into the interior of the two limiting holes respectively.

[0011] In a further embodiment, a controller is fixedly installed on the right side of the fixing cover, and two sets of support bases are fixedly connected to the bottom surface of the glue application table.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention utilizes two electric push rods installed inside the fixed cover, which, in conjunction with the coating cover and the coating roller, drive the coating roller to move flexibly up and down. At the same time, by utilizing the telescopic feature of the flexible hose, it ensures the normal delivery of adhesive after the height of the coating roller is adjusted. This allows the coating roller to flexibly apply adhesive to printed materials of different thicknesses, and it also has a structure for automatic adjustment of the coating height, thus improving the flexibility of adhesive application to printed materials.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-4In this utility model, a glue coating device for a special printing machine includes a glue coating table 1. A support cover 2 is fixedly installed on the upper surface of the glue coating table 1. A fixed cover 3 is fixedly embedded on the upper surface of the support cover 2. A material cylinder 4 is fixedly installed on the upper surface of the fixed cover 3. A guide hole 6 is opened on the upper surface of the fixed cover 3. A connecting pipe 13 is fixedly connected to the bottom end of the guide hole 6. A telescopic hose 11 is fixedly connected to the bottom end of the connecting pipe 13. Two electric push rods 7 are fixedly installed on the inner top wall of the fixed cover 3. The telescopic ends of the two electric push rods 7 are fixedly connected to a glue coating cover 8. A glue coating roller 10 is provided inside the glue coating cover 8. A solenoid valve 12 is fixedly connected to the outer surface of the connecting pipe 13. An injection port 5 is opened on the upper surface of the material cylinder 4. The glue liquid can be injected into the inside of the material cylinder 4 through the injection port 5. The guide hole 6 is used to guide and transport the glue liquid.

[0023] In a further embodiment, the bottom end of the telescopic hose 11 passes through the coating cover 8 and extends above the coating cover 8. The telescopic hose 11 is located above the coating roller 10. Two bearings 9 are fixedly embedded in the inner wall of the coating cover 8. The outer surfaces of the left and right ends of the coating roller 10 are fixedly connected to the inner rings of the two bearings 9 respectively. The telescopic hose 11 allows the adhesive to flow smoothly downwards. The two bearings 9 allow the coating roller 10 to rotate smoothly, ensuring stability when applying adhesive to printed materials.

[0024] In a further embodiment, a connecting plate 18 is fixedly connected to the back of the coating cover 8, and a coating plate 19 is fixedly connected to the bottom surface of the connecting plate 18. Two limiting holes 15 are opened on the inner side wall of the support cover 2, and two limiting blocks 16 are fixedly connected to the outer surface of the coating cover 8. The ends of the two limiting blocks 16 that are far apart from each other extend into the interior of the two limiting holes 15. A controller 14 is fixedly installed on the right side of the fixed cover 3, and two sets of support bases 17 are fixedly connected to the bottom surface of the coating table 1. With the setting of the coating plate 19, the printed matter after coating can be scraped flat again, which will make the coating of the printed matter more uniform. Through the cooperation of the limiting holes 15 and the limiting blocks 16, the coating cover 8 can be made more stable when it moves up and down. With the setting of the controller 14, it is convenient to control the device.

[0025] The working principle of this utility model is as follows: First, the glue is injected into the inside of the material cylinder 4. Then, the coating height is adjusted according to the thickness of the printed material. The controller 14 is used to start the extension and retraction of two electric push rods 7, which can drive the coating cover 8 and the coating roller 10 to move up and down. This facilitates the adjustment of the height between the coating roller 10 and the printed material. After the coating height is adjusted, the solenoid valve 12 is opened, which allows the glue to flow down through the connecting pipe 13 and the telescopic hose 11. The glue will flow on the coating roller 10, and then the coating roller 10 will coat the surface of the printed material. The brush plate 19 can be used to scrape the coated printed material again, which will make the coating of the printed material more uniform.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
