Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a gluing device for producing wood grain paper. Background Technology

[0002] Wood grain paper is a type of specialty paper. It typically uses virgin wood pulp kraft paper as the base paper, and then undergoes processes such as embossing and dyeing to produce wood grain paper with various colors and patterns. Due to its high aesthetic appeal, practicality, and cost-effectiveness, wood grain paper is used in various fields.

[0003] Wood grain paper requires surface coating during production, necessitating the use of coating equipment. However, most current coating equipment has certain shortcomings. Ordinary coating equipment typically sprays directly through nozzles, which can easily lead to uneven coating in certain areas. Furthermore, the amount of coating cannot be controlled according to the paper width, resulting in excessive coating at the edges and wasting glue. Utility Model Content

[0004] Based on the above description, this utility model provides a wood grain paper production glue coating device to solve the shortcomings of existing wood grain paper glue coating equipment, which results in uneven coating and easy waste of glue.

[0005] This utility model is achieved through the following technical solution:

[0006] A wood grain paper production gluing device includes a box body. The side wall of the box body is provided with an inlet and an outlet spaced apart vertically.

[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] Combination Figure 1-7 As shown, a wood grain paper production coating apparatus includes:

[0029] Box 1 is the main body of the entire glue coating device, and has an inlet 11 and an outlet 12 on its side wall. The inlet 11 is located at the top and the outlet 12 is located at the bottom.

[0030] The conveying channel 2 is set in an arc shape, and its two ends are connected to the inlet 11 and the outlet 12 respectively, so as to convey the paper on the inlet 11 to the outlet 12.

[0031] The conveying assembly 3 is located inside the housing 1 and is arranged on both sides of the conveying channel 2. It is used to assist in the conveying of paper, prevent it from shaking or jumping and causing wrinkles, thereby improving the production quality of wood grain paper.

[0032] The gluing component 4 is located inside the box 1 and below the conveying component 3. It works with the conveying component 3 to apply glue to one side of the paper, thereby ensuring the stability of the glue application process.

[0033] Specifically, in this embodiment, the conveying assembly 3 includes a coating roller 31 and an auxiliary roller 32 rotatably mounted inside the housing 1. The coating roller 31 is set as one and is arranged in the middle position of the housing 1. Several auxiliary rollers 32 are set and arranged in an arc along the conveying channel 2. Some of the auxiliary rollers 32 are close to the side wall of the coating roller 31 and leave a small gap. The paper is conveyed through the gap and its two sides are respectively attached to the surfaces of the auxiliary roller 32 and the coating roller 31.

[0034] In the above structure, both ends of the coating roller 31 and the auxiliary roller 32 should extend to the outside of the housing 1. One end of the coating roller 31 is provided with a transmission gear 33, and one end of one of the auxiliary rollers 32 is equipped with a driven gear 34. The transmission gear 33 and the driven gear 34 mesh with each other. At the same time, the other end of the coating roller 31 is also provided with a drive motor 37, so that the coating roller 31 drives the auxiliary roller 32 to rotate relative to each other. The gear ratio is adaptively adjusted according to the actual size of the roller. The drive motor 37 is fixedly installed on the surface of the housing 1 through a motor mount.

[0035] In addition, the other auxiliary rollers 32 should also rotate synchronously. Therefore, drive wheels 35 are set at both ends of each auxiliary roller 32, and belts 36 are used to connect each pair of adjacent auxiliary rollers 32. So when one of the auxiliary rollers 32 rotates, it will drive all the auxiliary rollers 32 to rotate in the same direction, thereby achieving the auxiliary conveying effect.

[0036] In the above structure, the transmission structure of the drive wheel 35 and the belt 36 can also be replaced by a gear and chain transmission structure. That is, gears are set on both sides of each auxiliary roller 32, and a chain is set between each pair of adjacent auxiliary rollers 32, which can also achieve the same transmission function as in the above structure.

[0037] The glue coating assembly 4 includes a glue storage tank 41 located directly below the glue coating roller 31. The bottom of the glue storage tank 41 is arc-shaped and contains a large amount of glue. The glue coating roller 31 is partially immersed in the glue. Therefore, when rotating, some glue will adhere to its surface, and the glue-coated side will adhere to the paper sidewall by rotating, thus completing the glue coating work. In this structure, the glue coating can be carried out continuously without interruption, so the work efficiency can be greatly improved.

[0038] Because the adhesive is viscous, the thickness of the adhesive adhering to the side wall of the coating roller 31 cannot be kept uniform. Therefore, a mounting plate 42 needs to be installed on the top surface of the adhesive storage tank 41. The mounting plate 42 is horizontally arranged and hollow inside, and a scraper 43 is movably inserted inside. The scraper 43 should also have a certain distance from the side wall of the coating roller 31. At the same time, an electric telescopic rod 44 is installed inside the mounting plate 42. The top end of the electric telescopic rod 44 is fixedly connected to the bottom end of the scraper 43. The position of the scraper 43 can be controlled by controlling the extension distance of the electric telescopic rod 44, so that the operator can adjust the thickness of the adhesive as needed, avoid adhesive waste, and allow the excess adhesive after scraping to flow back into the interior along the inner wall of the adhesive storage tank 41.

[0039] To facilitate timed glue supply, a glue delivery pipe should be installed on its side wall. The glue delivery pipe extends outward and connects to the external glue storage tank 1. A glue injection pump is also installed on the glue delivery pipe.

[0040] If the adhesive is left to stand for a long time, it is easy to solidify. Therefore, a stirring shaft 45 should be longitudinally arranged inside the adhesive storage tank 41. The stirring shaft 45 is equipped with stirring blades to expand the stirring range. A servo motor 46 is also installed on the surface of the tank 1. The output end of the motor is connected to the stirring shaft 45 for transmission. At the same time, the interior of the stirring shaft 45 is hollow, and a tubular electric heater 47 is installed inside it. Its two ends are movably installed inside the stirring shaft 45 using ball bearings, so that the adhesive can be maintained at a certain temperature during the stirring process to prevent it from solidifying.

[0041] At the bottom of the housing 1, there is also a glue drain port 48. The glue drain port 48 extends upward and connects to the bottom of the glue storage tank 41 for periodic cleaning of the internal glue. The connection between the glue drain port 48 and the glue storage tank 41 should be equipped with a solenoid valve 49 for convenient remote control by the staff. The solenoid valve 49 can be one of the DHE-0713P-ATOS solenoid valve 49 or the M-ET201 series solenoid valve 49.

[0042] During the conveying process, in order to prevent the adhesive from sticking to the inner wall of the conveying channel 2, the inner wall of the conveying channel 2 should also be coated with a non-stick coating.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
