Technical Field

[0001] This utility model relates to the field of paper product adhesive technology, specifically an adhesive applicator for paper product manufacturing and pasting. Background Technology

[0002] A coating device, also known as a coating machine, is a mechanical device used to apply liquid glue to the surface of textiles, cardboard boxes, or leather. In paper product manufacturing, the adhesive coating device is a key piece of equipment to ensure that paper, cardboard, or related materials can be accurately and evenly coated with glue during the production process.

[0003] When using existing gluing equipment, the paper may wrinkle and curl during the paper feeding process. If the gluing operation is performed directly, the gluing may not be complete, and the curled paper may even be folded, affecting the subsequent production of paper products. At the same time, the existing gluing equipment, which drips glue onto the gluing roller and then brushes the glue onto the paper, is prone to uneven glue thickness. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a gluing device for paper product manufacturing. By setting up a smoothing component, the device can, on the one hand, press the paper to prevent it from separating from the conveyor belt, and on the other hand, smooth the paper to ensure that the paper is flat for gluing. The gluing component also ensures uniform gluing thickness and cleans the glue on the electric gluing roller after gluing is completed.

The bottom of the electric push rod is connected to a lifting plate, and the bottom of the lifting plate is connected to two mounting blocks. The two ends of the electric glue-applying roller are rotatably connected to the mounting blocks through bearings.

[0017] Furthermore, multiple stirring rods are connected to the outside of the rotating rod, and the multiple stirring rods are staggered. A conduit is connected to the bottom of the equipment box, and one end of the conduit communicates with the cavity. The other end of the conduit extends to the lower surface of the lifting plate and is connected to a nozzle. A solenoid valve is provided on the conduit.

[0018] Furthermore, the bottom of the lifting plate is connected to two connecting blocks, and a smoothing roller is connected between the two connecting blocks via a bearing, with the smoothing roller close to the electric glue applicator roller.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0036] This application provides an adhesive applicator for bonding paper products in manufacturing. The following is a detailed description of this adhesive applicator. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0037] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] Please see Figure 1-10 In this embodiment, a gluing device for paper product manufacturing and pasting is provided, including: a workbench 1, a conveyor belt 101 installed on the top of the workbench 1, a pressing frame 2 and an equipment box 3 respectively installed on the top of the workbench 1, an electric gluing roller 402 provided at the bottom of the equipment box 3; a smoothing component provided at the bottom of the pressing frame 2 for smoothing the paper; and a gluing component provided between the equipment box 3 and the electric gluing roller 402 for applying glue to the paper.

[0040] The smoothing component serves two purposes: firstly, it presses the paper down to prevent it from detaching from the conveyor belt 101; secondly, it smooths the paper to ensure a flat surface for the gluing process. Thirdly, the gluing component ensures uniform gluing thickness and allows for slow stirring of the glue to prevent it from hardening due to the long gluing process. Finally, it cleans the glue off the electric gluing roller 402 after gluing is complete.

[0041] Example 2

[0042] Based on Embodiment 1, the smoothing component includes: multiple fixing blocks 201 connected to the bottom of the pressing frame 2, with fixing grooves 202 opened at the bottom of the fixing blocks 201; pressing blocks 204 disposed inside the fixing grooves 202, and pressing rollers 205 rotatably connected between two adjacent pressing blocks 204 via bearings, both pressing rollers 205 being inclined, and a return spring 203 connected between the top of the pressing block 204 and the fixing groove 202.

[0043] When applying glue to paper, to avoid wrinkles that could lead to uneven glue thickness or even missing glue in some areas, affecting the glue application quality, two inclined pressing rollers 205 can be used to press and fix the paper. Simultaneously, the paper is pressed and smoothed along the surface of the pressing rollers 205, ensuring a flat surface for the glue application. The return spring 203 continuously provides downward elasticity to the pressing block 204, keeping the pressing rollers 205 firmly against the paper. This applies pressure to the paper, flattening it, and ensures the paper adheres tightly to the conveyor belt 101, allowing the conveyor belt 101 to transport the paper.

[0044] Example 3

[0045] Based on Embodiment 1, the adhesive application assembly includes: a cavity 301 formed inside the equipment box 3; a rotary motor 302 installed on the top of the equipment box 3, with a rotary rod 303 driven and connected to the bottom of the rotary motor 302; an electric push rod 4 installed inside the equipment box 3, with a lifting plate 401 connected to the bottom of the electric push rod 4, and two mounting blocks connected to the bottom of the lifting plate 401; the two ends of the electric adhesive application roller 402 are rotatably connected to the mounting blocks through bearings; multiple stirring rods 304 are connected to the outside of the rotary rod 303, and the multiple stirring rods 304 are staggered; a conduit 305 is connected to the bottom of the equipment box 3, with one end of the conduit 305 communicating with the cavity 301, and the other end of the conduit 305 extending to the lower surface of the lifting plate 401 and connected to a nozzle; a solenoid valve is provided on the conduit 305; two connecting blocks are connected to the bottom of the lifting plate 401, and a smoothing roller 403 is connected between the two connecting blocks through bearings, with the smoothing roller 403 close to the electric adhesive application roller 402.

[0046] Before applying the glue, to prevent the glue inside the cavity 301 from solidifying, the rotating rod 303 can be rotated by the rotating motor 302, which in turn drives multiple stirring rods 304 to slowly stir the glue inside the cavity 301 to prevent it from solidifying. Then, the solenoid valve on the conduit 305 is opened, allowing the glue inside the cavity 301 to be discharged through the conduit 305 to the top of the electric glue applicator roller 402. At the same time, the lifting plate 401 is moved down by the electric push rod 4, so that the electric glue applicator roller 402 at the bottom of the lifting plate 401 is in close contact with the paper. At this time, the rotation speed of the electric glue applicator roller 402 is controlled to be consistent with the conveying speed of the conveyor belt 101, so that the paper can be glued by the electric glue applicator roller 402 when it passes between the electric glue applicator roller 402 and the conveyor belt 101.

[0047] After the glue falls onto the electric glue applicator roller 402, as the electric glue applicator roller 402 rotates, the glue accumulated on the electric glue applicator roller 402 is moved onto the smoothing roller 403, so that the smoothing roller 403 can smooth the glue on the electric glue applicator roller 402 and keep the glue thickness uniform.

[0048] Based on embodiment 3, further, the bottom of the equipment box 3 is provided with a movable groove 501, a drive motor 5 is installed on one side of the equipment box 3, a threaded rod 502 is driven and connected to one side of the drive motor 5, and one end of the threaded rod 502 is connected to the inner wall of the movable groove 501 through a bearing. A movable plate 503 is slidably connected in the movable groove 501, and a threaded hole 504 that cooperates with the threaded rod 502 is provided on the movable plate 503. A scraper 505 is connected to the bottom of the movable plate 503.

[0049] After the paper sheet is coated with glue, the solenoid valve on the guide tube 305 is closed to stop the glue discharge. At the same time, the electric push rod 4 drives the lifting plate 401 and the electric glue coating roller 402 to be raised until the electric glue coating roller 402 is aligned with the scraper 505. At this time, the drive motor 5 drives the threaded rod 502 to rotate, so that the threaded rod 502 drives the moving plate 503 to move in the movable groove 501 through the threaded hole 504. The movable groove 501 limits the moving direction and distance of the moving plate 503. The moving plate 503 drives the scraper 505 to press against the electric glue coating roller 402. At this time, the electric glue coating roller 402 continues to rotate, so that the scraper 505 scrapes off the glue adhering to the electric glue coating roller 402, so as to avoid the glue residue on the electric glue coating roller 402 solidifying and causing uneven glue thickness in subsequent coating.
