The base is equipped with a limiting mechanism, a gluing mechanism, and a pressing mechanism. The limiting mechanism includes a support frame, and a bidirectional lead screw is laterally rotatably connected to the inner side of the support frame. A handle is fixedly connected to one end of the bidirectional lead screw, and a driving block is threadedly connected to the surface of the bidirectional lead screw. In this utility model, by rotating the handle of the limiting mechanism, the handle drives the bidirectional lead screw to rotate.

Description

Technical Field

[0001] This utility model relates to the field of adhesive device technology, and in particular to a multi-layer adhesive device for corrugated paper. Background Technology

[0002] In the production of corrugated paper products, the bonding of multiple layers of corrugated paper is a crucial step. While common corrugated paper bonding devices can achieve basic bonding functions, in practice, tension fluctuations, mechanical vibrations during paper transport, and the lack of effective positioning guidance between layers often lead to misalignment of the corrugated paper during transport and bonding. Once misalignment occurs, the layers cannot be accurately aligned and bonded, affecting the bonding quality and resulting in uneven edges, weak adhesion, or even delamination. This significantly reduces the product yield and also hinders the subsequent processing and manufacturing of packaging products such as cartons. Summary of the Invention

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a corrugated paper multilayer bonding device, including a base, the base being provided with a limiting mechanism, an adhesive coating mechanism and a pressing mechanism;

[0028] The limiting mechanism includes a support frame, on the inner side of which a bidirectional lead screw 202 is rotatably connected. A handle 205 is fixedly connected to one end of the bidirectional lead screw 202. A drive block 203 is threaded onto the surface of the bidirectional lead screw 202. A limiting plate 204 is fixedly connected to the bottom of the drive block 203. The glue application mechanism 3 includes a fixed frame 301, on the inner side of which a drive roller 302, a first glue application roller 304, and a second glue application roller 306 are rotatably connected, as are driven rollers 303, 305, and 307. A drive motor 308 is fixedly connected to the surface of the frame 1. One end of the drive roller 302, the first glue-applying roller 304, and the second glue-applying roller 306 are all fixedly connected to the output end of the drive motor 308. A glue storage tank 309 and a glue storage tank 310 are fixedly connected to the inner side of the frame 301. Parts of the first glue-applying roller 304 and the second glue-applying roller 306 are located inside the first glue storage tank 309 and the second glue storage tank 310. The pressing mechanism 4 includes a U-shaped frame 401. A lower pressing roller 402 is rotatably connected to the inner side of the U-shaped frame 401. The surface of the U-shaped frame 401 is fixedly connected to... A second drive motor 408 is connected, and the output end of the second drive motor 408 is fixedly connected to one end of the lower pressing roller 402. A threaded groove 404 is opened on the surface of the U-shaped frame 401, and a screw 405 is threadedly connected inside the threaded groove 404. A mounting bracket 403 is rotatably connected to the bottom of the screw 405, and an upper pressing roller 407 is rotatably connected to the inner side of the mounting bracket 403. A handwheel 406 is fixedly connected to the top of the screw 405, and a protective sleeve 13 is fixedly connected to the surface of the handwheel 406. A handle sleeve 12 is fitted on the surface of the handle 205, and the protective sleeve 13 is also fitted on the handle. Both the handle sleeve 12 and the handle sleeve 12 are made of elastic rubber. The surface of the support frame 201 is provided with a groove 5. The surface of the drive block 203 is fixedly connected to a limit block 6. The limit block 6 is slidably connected inside the groove 5. There are two sets of drive blocks 203. The two sets of drive blocks 203 are symmetrically distributed on both sides of the middle part of the surface of the bidirectional screw 202. The interior of the glue storage tank 1 309 and the glue storage tank 2 310 are respectively fixedly connected to scraper 11 and scraper 2 15. Scraper 11 and scraper 2 15 abut against the surfaces of glue coating roller 1 304 and glue coating roller 2 306.

[0029] In this embodiment, by rotating the handle 205 of the limiting mechanism 2, the handle 205 drives the bidirectional lead screw 202 to rotate. The rotation of the bidirectional lead screw 202 causes the clamping plates at the bottom of the two sets of driving blocks 203 to move towards each other. This allows the distance between the two sets of limiting plates 204 to be adjusted according to the width of the paper. At the same time, it can also effectively limit and guide the interlayer paper, preventing paper misalignment. Misalignment of the interlayer paper would affect the quality of subsequent corrugated board bonding, ensuring the edge alignment of the interlayer paper and improving the production quality of corrugated board.

[0030] The gluing mechanism 3 utilizes multiple rollers (drive roller 302, gluing roller, and driven roller) in coordination. The drive roller 302 and gluing roller are connected to the drive motor 308, ensuring smooth conveying of the corrugated paper during the gluing process. The first gluing roller 304 and the second gluing roller 306 are partially located within the glue storage tank, enabling automatic glue application and uniform gluing of the upper and lower surfaces of the corrugated paper, thus improving gluing efficiency and quality. The pressing mechanism 4 presses the multi-layered glued corrugated paper together. The drive motor 408 drives the lower pressing roller 402 to rotate, providing power for the conveying of the corrugated paper. Rotating the handwheel 406 causes the screw 405 to rotate within the threaded groove 404, which in turn moves the mounting frame 403 up and down, adjusting the distance between the upper pressing roller 407 and the lower pressing roller 402 to accommodate the pressing needs of corrugated paper of different thicknesses, enhancing the applicability of the device. The protective ring 13 on the surface of the handwheel 406 and the handle sleeve 12 on the surface of the handle 205 are both made of elastic rubber, which can increase the friction when the operator holds the hand, prevent the hand from slipping, and provide a certain degree of comfort to reduce operator fatigue. The sliding groove 5 on the surface of the support frame 201 cooperates with the limiting block 6 on the surface of the drive block 203 to guide and limit the movement of the drive block 203, ensuring that the drive block 203 can move smoothly and accurately under the drive of the bidirectional screw 202, preventing it from shaking or deviating, and ensuring the adjustment accuracy of the limiting plate 204. The scraper 11 and scraper 2 15 in the glue storage tank abut against the surface of the glue coating roller, which can scrape off the excess glue on the surface of the glue coating roller, making the glue layer thickness on the surface of the glue coating roller uniform, avoiding glue overflow during corrugated paper bonding due to excessive glue, and improving the glue coating quality and the bonding effect of the corrugated paper.

[0031] Example 2: Figure 3 - Figure 5As shown, the surface of the U-shaped frame 401 is provided with a guide groove 10, the surface of the mounting frame 403 is fixedly connected with a guide rod 9, the guide rod 9 is inserted into the guide groove 10, the surface of the lower pressing roller 402 is fixedly connected with a protective sleeve 7, the surface of the upper pressing roller 407 is fixedly connected with a protective sleeve 8, the protective sleeve 7 and the protective sleeve 8 are made of soft material, the inner surface of the fixing frame 301 is provided with a square groove 14, the inside of the square groove 14 is slidably connected with a block 16, the surface of the block 16 is fixedly connected with a spring 17, the other end of the spring 17 is fixedly connected to the bottom surface of the inside of the square groove 14, and both ends of the driven roller 307 are inserted into the inside of the block 16.

[0032] In this embodiment, the guide groove 10 on the surface of the U-shaped frame cooperates with the guide rod 9 on the surface of the mounting frame 403 to guide the up-and-down movement of the upper pressing roller 407, ensuring that the upper pressing roller 407 remains stable when adjusting its height, avoiding tilting, and guaranteeing the stability and quality of the pressing process. The protective sleeves on the surfaces of the lower pressing roller 402 and the upper pressing roller 407 are made of soft material, which can prevent damage to the corrugated paper during the pressing process. At the same time, the soft material has a certain degree of elasticity, which can better adapt to the shape of the corrugated paper and improve the pressing effect. By inserting the two ends of driven roller 1 303, driven roller 2 305 and driven roller 3 307 into the interior of block 16, the block 16 in the square groove 14, together with the spring 17, can adaptively adjust the spacing between glue roller 1 304 and driven roller 2 305, glue roller 2 306 and driven roller 3 307, as well as between drive roller 302 and driven roller 1 303, according to the thickness of the paper. This ensures good contact between the rollers and smooth paper transfer during the entire glue coating process, which helps to make the glue coating operation go smoothly.

[0033] The working principle of this embodiment is as follows: When in use, the core, top layer and bottom layer of the corrugated paper that needs to be bonded in multiple layers are first placed on the base 1. Then, the corrugated paper is limited by the limiting mechanism 2. During operation, the handle 205 at one end of the bidirectional lead screw 202 is rotated. Since the bidirectional lead screw 202 is laterally rotatably connected to the inner side of the support frame 201, and its surface is threaded with a drive block 203, the drive block 203 will move accordingly on the bidirectional lead screw 202 as the handle 205 is rotated. The movement of the drive block 203 is restricted by the sliding groove 5 on the surface of the support frame 201 and the limiting block 6 fixedly connected to it. The limiting block 6 slides within the sliding groove 5, ensuring that the drive block 203 can move smoothly and accurately. At the same time, the two sets of drive blocks 203 are symmetrically distributed on both sides of the middle part of the surface of the bidirectional lead screw 202, so that they can move synchronously and symmetrically, driving the limiting plate 204 fixedly connected at the bottom to adjust the spacing, thereby limiting the two sides of the corrugated paper according to the width of the corrugated paper, preventing the corrugated paper from shifting during subsequent processing. After the limiting is completed, the lower layer, core and upper layer of the corrugated paper are respectively... The corrugated paper is then placed between the active roller 302 and driven roller 303, the glue-applying roller 304 and driven roller 305, and the glue-applying roller 304 and driven roller 307. Subsequently, the drive motor 308 of the glue-applying mechanism 3 is activated. The drive motor 308 drives the active roller 302, glue-applying roller 304, and glue-applying roller 306 to rotate synchronously. With the cooperation of the active roller 302 and the driven rollers 303, 305, and 307, the layers of corrugated paper are smoothly conveyed inside the fixed frame 301. During the conveying process, the glue-applying rollers 304 and 306 will respectively move from their corresponding... Glue is absorbed into glue storage tanks 309 and 310. Simultaneously, scraper 11 in glue storage tank 309 and scraper 15 in glue storage tank 310 come into contact with the surfaces of coating rollers 304 and 306, scraping away excess glue and ensuring a uniform glue layer thickness. This allows for even glue application to the corrugated paper core and the lower surface of the top layer, guaranteeing coating quality. Driven rollers 303, 305, and 307 are inserted into blocks 16 at both ends. Blocks 16 are connected to square grooves 1 on the inner surface of the fixing frame 301 via springs 17. The bottom surfaces are connected, and relying on the elastic buffering effect of spring 17, the three driven rollers can adaptively adjust when the thickness of the corrugated paper changes or the conveying is uneven, maintaining the smooth conveying of the corrugated paper. After being coated with glue, the corrugated paper continues to be conveyed forward into the pressing mechanism 4. The drive motor 408 of the pressing mechanism 4 is started, and the drive motor 408 drives the lower pressing roller 402 to rotate, providing power for the conveying of the corrugated paper. The operator can adjust the distance between the upper pressing roller 407 and the lower pressing roller 402 by turning the handwheel 406 according to the thickness of the corrugated paper. When the handwheel 406 rotates, it drives the screw 405 to rotate in the threaded groove 404 opened on the surface of the U-shaped frame. The bottom of the screw 405 is rotatably connected to the mounting frame 403. During the rotation of the screw 405...The mounting frame 403 moves smoothly up and down with the cooperation of the guide groove 10 and the guide rod 9. The guide rod 9 is inserted into the guide groove 10 to ensure the accurate movement direction of the mounting frame 403, thereby driving the upper pressing roller 407 to adjust to the appropriate position. When the corrugated paper passes through the upper and lower pressing rollers 402, the protective sleeve 7 on the surface of the lower pressing roller 402 and the protective sleeve 8 on the surface of the upper pressing roller 407 (both made of soft material) can not only avoid damage to the corrugated paper, but also better adhere to the corrugated paper by utilizing its elasticity, so as to effectively press the multi-layered coated corrugated paper, making each layer of corrugated paper firmly bonded together. During the entire operation, the handle sleeve 12 on the surface of the handle 205 and the protective ring 13 on the surface of the handwheel 406 (both made of elastic rubber material) can increase the friction when the operator holds the handle, making operation easier and improving the comfort of operation.
