Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically, to a gluing device for printing. Background Art

[0002] Before laminating multi-layer paper products, glue must be applied. Conventional gluing mechanisms often place the glue roller below and the drive roller above. This allows the glue tank to be placed below the paper product, eliminating the need for a hole in the bottom of the tank and simplifying sealing. If the middle material of a layer of paper product requires glue coating on both sides simultaneously, a gluing mechanism with the glue roller positioned above is required. Accordingly, the present invention provides a gluing device for printing. Utility Model Content

[0005] The utility model is further configured as follows: the first grooves are arranged in a ring array with equal angles around the axis of the glue coating upper roller.

[0006] The utility model is further configured as follows: the first grooves are arranged at equal intervals along the axial direction of the glue coating upper roller.

[0007] The utility model is further configured as follows: the scraper extends along the circumference of the glue coating upper roller.

[0008] The utility model is further configured as follows: a plurality of second grooves with equal adjacent angles are distributed on the roller surface of the transmission lower roller, and the second grooves extend along the axial direction of the transmission lower roller.

[0009] To sum up, the utility model has the following beneficial effects: the gluing device for printing involved in the utility model adopts an upper rubber roller structure, combined with a conventional lower rubber roller gluing mechanism, which can realize the function of simultaneous gluing on both sides of the middle material of a layer of paper products, with complete overall functions and strong practicality.

[0013] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figures 1 to 3 As shown, the present embodiment involves a gluing device for printing, comprising an upper gluing roller 1 and a lower transmission roller 2, and also comprising a glue tank 3. A process hole 4 is provided at the bottom of the glue tank 3. The upper gluing roller 1 is rotatably connected in the glue tank 3 and partially extends out of the process hole 4. The left and right ends of the upper gluing roller 1 are tightly attached to the tank wall of the glue tank 3. The front and rear sides of the upper gluing roller 1 are respectively provided with scrapers 5 provided on the glue tank. The scrapers 5 are tightly attached to the roller surface of the upper gluing roller 1. A first groove 6 is formed on the roller surface of the upper gluing roller 1, and a cotton block 7 extending out of the groove is provided in the first groove 6.

[0017] Furthermore, the first grooves 6 are arranged in a circular array with equal angles around the axis of the upper glue coating roller 1 ; the first grooves 6 are also arranged in an equidistant manner along the axial direction of the upper glue coating roller 1 .

[0018] Furthermore, the scraper 5 extends along the circumference of the glue coating upper roller 1 .

[0019] In this embodiment, an appropriate amount of glue is first placed in the glue tank 3 to submerge the upper glue roller 1, and then the intermediate material of the paper product is conveyed through the upper glue roller 1 and the transmission lower roller 2. During this period, the upper glue roller 1 rotates relative to the glue tank 3, and the cotton block 7 rotated out of the glue tank 3 is adhered with glue, and the glue is applied to the intermediate material of the paper product to perform the gluing operation.

[0020] When the cotton piece 7 extending out of the first groove 6 is transferred from the inside of the glue tank 3 to the outside of the glue tank 3 , the cotton piece 7 will pass through the scraper 5 and be appropriately squeezed by the scraper 5 to prevent it from absorbing excessive glue and dripping.

[0021] The left and right ends of the glue-spreading roller 1 are placed in close contact with the walls of the glue tank 3, and the scraper 5 is placed in close contact with the roller surface of the glue-spreading roller 1 to ensure sealing and prevent glue seepage. If necessary, a seal can be installed at the intersection to improve the sealing level.

[0022] Example 2

[0023] See also Figures 1 to 3 As shown, the present embodiment involves a gluing device for printing, which is further configured on the basis of Example 1, that is, a plurality of adjacent second grooves 8 with equal angles are arranged on the roller surface of the transmission lower roller 2, and the second grooves 8 extend along the axial direction of the transmission lower roller 2.

[0024] In this embodiment, the second groove 8 is provided to increase friction, thereby making the transmission stable and non-slip.

[0025] The printing gluing device involved in the utility model adopts a structure in which the rubber roller is placed on top and is matched with a conventional gluing mechanism with the rubber roller placed on the bottom, so as to realize the function of gluing both sides of the middle material of a layer of paper products at the same time. The overall function is perfect and the practicability is strong.
