Description

Technical Field

[0001] This utility model relates to the field of dipping equipment technology, specifically to a dipping equipment for processing topcoat stickers with adjustable dipping thickness. Background Technology

[0002] In the fields of furniture manufacturing, decoration and renovation, and electronic product casings, topcoat stickers are widely used due to their advantages such as strong decorative properties, wear resistance and easy cleaning. As the core process of topcoat sticker processing, the uniformity and precision of the glue thickness directly determine the bonding strength, surface flatness and service life of the topcoat sticker. The stable state of the glue is the basic premise for ensuring the continuous operation of the glue dipping process. Most adhesive impregnation equipment has a fixed squeegee structure, which prevents precise adjustment of the squeegee's height according to actual processing needs. This limits the ability to adjust the impregnation thickness for different sizes of topcoat stickers, thus having certain limitations. In addition, the adhesives used in topcoat sticker processing are mostly hot melt adhesives, water-based adhesives, and other colloids with a certain viscosity. This makes the adhesive prone to solidification due to decreased fluidity during sticker preparation. To address these issues, the inventor proposes an adjustable impregnation thickness equipment for topcoat sticker processing. Utility Model Content

Thus, this paper will not elaborate on these aspects. Furthermore, this solution aims to protect the physical structure, but does not provide protection for the circuitry and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0020] A guide groove is provided at the center of the side end of the transmission box 3, and the sliding frame 36 is slidably connected to the guide groove.

[0021] By adopting the above technical solution and setting the guide groove, it is to facilitate the sliding frame 36 to slide and lift, thereby driving the fixedly connected U-shaped connecting shaft 37 to lift.

[0022] A stepper motor 13 is installed at the front end of the impregnation tank 1 near the transmission box 3. The output end of the stepper motor 13 passes through the impregnation tank 1 and is fixedly connected to one of the guide plates 31.

[0023] By adopting the above technical solution, the working stepper motor 13 is started, thereby causing one of the fixedly connected guide plates 31 to rotate, achieving the effect of angle adjustment.

[0024] A guide shaft 22 is symmetrically slidably inserted at the top of the U-shaped mounting plate 2 near the center, and the bottom end of the guide shaft 22 is fixedly connected to the scraper plate 23.

[0025] By adopting the above technical solution, a limit stop is provided at the top of the guide shaft 22 to prevent excessive sliding from causing component collision.

[0026] A drive roller 21 is rotatably connected between the inner walls of the U-shaped mounting plate 2 and near the center.

[0027] By adopting the above technical solution, the surface of the transmission roller 21 is sandblasted to enhance the friction with the topcoat sticker and prevent the sticker from shifting during conveying.

[0028] A vertical plate 11 is symmetrically fixedly connected to the top of the glue-impregnation tank 1 near the center of the other side, and a cleaning roller 12 is symmetrically rotatably connected between the two vertical plates 11 near the center.

[0029] By adopting the above technical solution, the two vertical plates 11 and the U-shaped mounting plate 2 are symmetrically distributed. The cleaning roller 12 is wrapped with a high-density sponge sleeve and has ultra-fine nylon bristles on its surface, which can effectively remove dust and impurities from the surface of the paint sticker without damaging the substrate.

[0030] A transmission gear 4 is symmetrically and rotatably connected to the bottom end of the impregnation tank 1 near the center. A stirring paddle 44 is symmetrically and rotatably connected to the bottom end of the impregnation tank 1 near the center, and the bottom end of the stirring paddle 44 passes through the impregnation tank 1 and is fixedly connected to the transmission gear 4.

[0031] By adopting the above technical solution, two stirring paddles 44 are set up to achieve the effect of stirring the glue liquid in the impregnation tank 1 and prevent it from solidifying.

[0032] A rack 41 is slidably connected to the bottom end of the impregnation tank 1 near the transmission gear 2 4, and the rack 41 meshes with the two transmission gears 2 4. A mounting block 2 42 is fixedly connected to the side end of the rack 41.

[0033] By adopting the above technical solution, the sliding rack 41 is set to facilitate the synchronous rotation of the two transmission gears 4. The bottom of the impregnation tank 1 is provided with a long groove, and the top of the rack 41 is provided with a matching sliding block to facilitate the horizontal movement of the rack 41. The mounting block 42 is set on the side of the rack 41 to facilitate the horizontal movement of the rack 41.

[0034] A reciprocating electric cylinder 43 is installed at the bottom of the glue-impregnation tank 1 near the center of one side, and the output end of the reciprocating electric cylinder 43 is fixedly connected to the mounting block 42.

[0035] By adopting the above technical solution, the working reciprocating electric cylinder 43 is started, thereby causing the fixedly connected mounting block 42 to drive the rack 41 to move horizontally.

[0036] A scale is fixedly connected to the front end of the glue-impregnation tank 1 near the transmission box 3.

[0037] By adopting the above technical solution, the sliding frame 36 and the scale are misaligned. The scale will not affect the lifting and lowering of the sliding frame 36. Furthermore, the adjustment height of the scraper plate 23 can be directly read through the scale when the sliding frame 36 is lifted and lowered.

[0038] Working principle: In use, this device first adds an appropriate amount of adhesive to the impregnation tank 1. Then, the topcoat sticker passes through the two cleaning rollers 12 and winds around to the bottom of the guide plate 31, finally inserting between the scraper 23 and the drive roller 21 (the feeding and receiving components of the topcoat sticker are not protected and are not described in detail; these components are publicly known technologies). Through the working stepper motor 13, and with the cooperation of two meshing transmission gears 38, the two guide plates 31 can rotate synchronously in opposite directions, thereby achieving… Adjusting the angle of the guide plate 31, and then, with the cooperation of the first bevel gear 33 and the second bevel gear 34, the screw 35 drives the threaded sliding frame 36 to rise and fall. This allows the scraper 23 to simultaneously rise and fall under the action of the two guide shafts 22 and the U-shaped connecting shaft 37, thereby precisely controlling the adhesive thickness of the sticker (the adjustment height of the scraper 23 can be read intuitively using the set scale), improving the uniformity of adhesive impregnation (which can meet the different requirements of different specifications of topcoat stickers for adhesive thickness). By activating the reciprocating electric cylinder 43, the fixedly connected mounting block 42 drives the rack 41 to move horizontally back and forth. This causes the two meshing transmission gears 4 to rotate synchronously, thereby driving the two fixedly connected stirring paddles 44 to rotate, thus achieving the effect of stirring the adhesive in the dipping tank 1. This prevents the adhesive in the dipping tank 1 from solidifying (the speed of the stirring paddles 44 can be adjusted by adjusting the reciprocating electric cylinder 43 to avoid affecting the adhesive dipping process, or the stirring paddles 44 can be stopped during the dipping process to ensure that the adhesive does not solidify).

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
