Description

Technical Field

[0001] This utility model relates to the field of gluing device technology, specifically a gluing positioning device for the outer casing paper to prevent wrinkling. Background Technology

[0002] Gluing equipment, also known as glue applicator or glue coating equipment, is a type of mechanical equipment widely used in various industries. It is mainly used for bonding materials such as paper, cardboard, and film. The basic principle is to evenly apply glue to the surface of the materials to be bonded, and then press it to make the glue fully contact and bond with the materials.

[0003] As disclosed in CN217989812U, this utility model discloses a packaging paper anti-wrinkle gluing device. A gluing machine is installed on one side of the upper part of the machine body, and a scraping structure is installed on the other side of the gluing machine to remove residual glue. A limiting mechanism is installed on the upper part of the same side of the gluing machine and the scraping structure to press and hold the packaging paper. An infrared sensor is installed on the inner wall of one side of the upper part of the gluing machine. This utility model has the following advantages: the packaging paper first passes between the first and second pressure rollers, and then contacts the gluing roller. When the packaging paper passes below the infrared sensor, the controller controls the operation of the second electric telescopic rod, and finally, the first and second pressure rollers work together to press and hold the packaging paper, effectively preventing wrinkling. After production, the scraper on the storage frame contacts the outer wall of the gluing roller, which can remove residual glue from the gluing roller into the storage frame, thus preventing residual glue from solidifying on the gluing roller.

[0004] The aforementioned patent is mainly applied to the gluing of packaging paper. However, if the outer paper is not treated with anti-wrinkle measures before gluing, firstly, the flatness of the paper cannot be guaranteed during the gluing process. Due to the irregular wrinkles that may exist on the surface of the paper, it is difficult to ensure that the glue can evenly cover the entire surface of the paper. This directly leads to uneven glue distribution, which in turn affects the bonding effect between the paper sheets and may result in some areas not being firmly bonded, creating a potential risk of delamination. Secondly, the wrinkles of the paper will be magnified or aggravated during the gluing process, thereby destroying the integrity and flatness of the entire outer paper. This uneven surface not only gives people an uncomfortable feeling visually and reduces the aesthetics of the product, but may also lead to a decrease in durability and a shortened product lifespan due to uneven stress during long-term use.

[0023] Specifically, mounting blocks 313 are fixedly connected to both sides of the two placement boxes 35, and the bottom of the mounting blocks 313 is fixedly connected to the conveying device 1.

[0024] In this embodiment, the mounting block 313 connects the placement box 35 to the conveying device 1, thereby improving the stability of the placement box 35.

[0025] Specifically, sliders 314 are fixedly connected to both sides of the U-shaped block 33, and grooves that are compatible with sliders 314 are opened on both sides of the inner cavity of the work box 31.

[0026] In this embodiment, the combined use of slider 314 and groove guides the U-shaped block 33, further ensuring the movement trajectory of the U-shaped block 33.

[0027] Specifically, guide grooves 315 are provided on both sides of the inner cavity of the mobile box 310, and guide blocks 316 are slidably connected to the inner cavity of the guide grooves 315. The opposite sides of the two guide blocks 316 are fixedly connected to the scraper 312.

[0028] In this embodiment, the guide groove 315 and the guide block 316 work together to limit the position of the scraper 312, thereby improving the stability of the scraper 312.

[0030] In this embodiment, the top plate 5 and the rotating wheel 6 work together to provide a certain support force for the conveying device 1 when the anti-wrinkle structure 3 is operating to flatten the outer paper 4.

[0031] Specifically, several springs 311 are fixedly connected to the inner cavity of the mobile box 310, and the bottom end of the springs 311 is fixedly connected to the scraper 312.

[0032] In this embodiment, the spring 311 ensures that the electric telescopic rod 317 moves smoothly during extension and retraction, reducing impact and vibration, thereby extending the service life of the electric telescopic rod 317.

[0033] The working principle and usage process of this utility model are as follows: The user turns on the conveyor device 1 and places the outer cover paper 4 on top of the conveyor device 1. When the conveyor device 1 transports the outer cover paper 4 to the bottom of the anti-wrinkle structure 3, the user turns off the conveyor device 1 and turns on the electric telescopic rod 32. The output end of the electric telescopic rod 32 pushes the U-shaped block 33 downward. During the downward movement of the U-shaped block 33, it pushes the two transmission plates 34 to move back and forth around the U-shaped block 33 as the axis, so that the two transmission plates 34 form a V-shape. The movable plate 34 drives the movable block 39 to move downwards and simultaneously move in opposite directions via the fixed frame 38. The movable block 39 drives the scraper 312 downwards via the spring 311, causing the scraper 312 to contact the outer casing paper 4. The scraper 312 drives the pressure sensor 319 to contact the outer casing paper 4. Under the pushing force of the electric telescopic rod 32, the two transmission plates 34 continue to move in opposite directions. Because the scraper 312 is in contact with the outer casing paper 4, the force of the two movable blocks 39 continuing to move in opposite directions drives the connecting plates on both sides. 37 moves back-to-back around support rod 36. Under the action of connecting plate 37, the movable block 39 remains parallel and its movement trajectory is inclined upward. As the two movable blocks 39 continue to move back-to-back, the movable block 39 drives the moving box 310 to perform the same movement as the movable block 39. When the moving box 310 moves upward, the pressure sensor 319 detects whether the scraper 312 is in contact with the outer cover paper 4. When it is detected that the scraper 312 is not in contact with the outer cover paper 4, The electric telescopic rod 317 starts working. The output end of the electric telescopic rod 317 drives the scraper 312 to move downward through the connecting block 318, so that the scraper 312 is always in contact with the outer cover paper 4 during the movement and flattens the outer cover paper 4. After the anti-wrinkle treatment of the outer cover paper 4 is completed, the output end of the electric telescopic rod 317 drives the scraper 312 to return to its original position through the connecting block 318. At this time, the conveying device 1 is turned on again to transfer the outer cover paper 4 to the inner cavity of the gluing device 2 for gluing.
