Description

Technical Field

[0001] This utility model relates to the field of decorative paper processing technology, specifically to a width-adjustable conveying device for decorative paper processing. Background Technology

[0002] Currently, the commonly used technology in the conveying and processing of decorative paper involves setting up several tension rollers. These tension rollers are arranged in parallel and have different installation heights. The traction force is generated by the height difference between adjacent tension rollers, thereby traction and conveying the decorative paper. Structurally, the tension rollers in existing technologies are mostly smooth rods, meaning the roller surface is smooth and has no limiting structure.

[0003] In practical applications, the aforementioned tensioning rollers exhibit significant technical defects: Because decorative paper is easily affected by factors such as airflow in the processing environment and tension fluctuations during process transitions, the smooth-bar tensioning rollers cannot constrain the lateral position of the decorative paper, leading to easy deviation during traction and conveying. This deviation not only reduces the alignment accuracy of the patterns, affecting the quality of subsequent processing steps, but can also, in severe cases, cause edge damage, increase raw material loss, and reduce production efficiency.

[0004] To address the aforementioned deviation problem, some technical solutions have improved the tension roller by adding annular limiting bosses at both ends. These bosses physically block the edges of the decorative paper, effectively preventing it from shifting outwards during traction and ensuring it is conveyed along the preset path in the correct lateral position, thus mitigating the deviation problem to some extent.

[0005] However, since the limiting boss and the tensioning roller are an integrated structure (or a fixed connection structure), this type of tensioning roller can only be used to transport decorative paper of a single width. When production needs change and different widths of decorative paper need to be used for processing, the tensioning roller with the limiting boss cannot form a stable lateral limit for the new decorative paper because the width of the new decorative paper does not match the distance between the two limiting bosses (either the width is greater than the distance, making it impossible to fit, or the width is less than the distance, making it impossible to form an effective limit). The problem of the decorative paper running off-center still exists, resulting in extremely poor versatility of the tensioning roller, which cannot meet the flexible production needs of processing decorative paper of multiple specifications. Utility Model Content

[0006] Therefore, in order to overcome any of the above-mentioned shortcomings, this utility model provides a width-adjustable conveying device for decorative paper processing. The conveying device can adjust the distance between the two baffles through a fixed baffle on the support body and a movable baffle, thereby facilitating the support and conveying of decorative paper of different widths. This avoids the problem of deviation when the traditional tension roller conveys decorative paper of different widths. Combined with the tightening roller, the decorative paper can be pulled to realize the automatic conveying of decorative paper.

[0007] The utility model is implemented as follows: a width-adjustable conveying device for decorative paper processing includes a support body with guide rollers on both sides of the top. A tightening roller is positioned outside any one of the guide rollers to pull the decorative paper along the support. A fixed baffle is installed on one side of the top of the support and is kept perpendicular to the guide roller. A movable baffle is movably installed on the other side of the top of the support and maintains an adjustable distance from the fixed baffle. The decorative paper is placed on fixed baffles and movable baffles at both ends and is conveyed and moved by the limiting action of the two baffles.

[0008] Preferably, the movable baffle includes a horizontal end and a vertical end. The vertical end is vertically connected to the middle of the horizontal end. A connecting hole is provided in the vertical direction at the end of the horizontal end away from the fixed baffle. An adjusting rod is provided on the side of the vertical end away from the fixed baffle. The end of the vertical end away from the tightening roller is an inclined guide portion.

[0009] Preferably, the support body has a strip-shaped hole, which is perpendicular to the fixed baffle. The movable baffle is attached to the support body and is movably connected to the strip-shaped hole through the connecting hole by a fastening connector for position adjustment.

[0010] Preferably, a mounting plate is provided on the side of the support body away from the fixed baffle, and a U-shaped hole is provided on the mounting plate. The movable baffle is fixed or adjusted by an adjusting rod passing through the U-shaped hole and in conjunction with a locking nut.

[0011] Preferably, a parallel pressing roller is also provided above the tightening roller. The pressing roller is slidably mounted on the frame in the vertical direction through slides at both ends. An adjusting handwheel is also provided above the frame. The connecting rod at one end of the adjusting handwheel is rotatably connected to the slide. The adjusting handwheel passes through the frame through the connecting rod and is threadedly connected.

[0012] Compared with the prior art, the present invention has the following advantages: This conveying device can flexibly adapt to decorative paper of different widths by adjusting the distance between the fixed baffle and the movable baffle on the support body. This solves the problem that the traditional tensioning roller can only correspond to a single width and has poor versatility. At the same time, the baffles on both sides limit the decorative paper on both sides, completely avoiding the problems of the traditional smooth roller running off track and the fixed boss roller failing to adapt. Combined with the tightening roller, the decorative paper can be automatically traction and conveyed.

[0013] Then, the conveying device supports the decorative paper by means of baffles, so that the decorative paper maintains a gap with the support body during conveying, thereby avoiding the problem that the decorative paper may get stuck in the gap between the baffles and the support body when it is conveyed directly on the support body, and ensuring that the decorative paper will not be damaged during conveying.

[0014] Finally, the conveying device achieves the first adjustment and fixation of the movable baffle and the support body by reasonably setting the connection method between the movable baffle and the support body, using the strip hole on the support body and the connection hole on the movable baffle, combined with the fastening connector. The second adjustment and fixation of the movable baffle and the support body is achieved by using the U-shaped hole on the mounting plate and the adjusting rod on the movable baffle, combined with the locking nut. This effectively improves the connection stability between the movable baffle and the support body and avoids the movable baffle from moving due to any loose nut. Attached Figure Description

[0018] As described in the background section, decorative paper is usually traction and conveyed using tension rollers during the processing. However, existing tension rollers are usually in the shape of a smooth rod, which is prone to deviation when conveying paper. Although setting limiting bosses at both ends of the tension roller can solve the deviation problem, this method can only convey paper of a single width, resulting in reduced practicality.

[0019] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 4 This utility model provides a width-adjustable conveying device for decorative paper processing, including a support body 1, with guide rollers 2 on both sides of the top. A tightening roller 9 is positioned outside any one of the guide rollers 2 to pull the decorative paper on the support 1. A fixed baffle 3 is set on one side of the top of the support body 1 and is kept perpendicular to the guide roller 2; The movable baffle 4 is movably installed on the other side of the top of the support 1 and the distance between it and the fixed baffle 3 is adjustable; The decorative paper is placed on fixed baffles 3 and movable baffles 4 at both ends and is conveyed and moved by the limiting action of the two baffles.

[0020] Please refer to the appendix carefully. Figure 4 In this embodiment, the movable baffle 4 includes a horizontal end 401 and a vertical end 402. The vertical end 402 is vertically connected to the middle of the horizontal end 401. A connecting hole 403 is provided in the vertical direction at the end of the horizontal end 401 away from the fixed baffle 3. An adjusting rod 405 is provided on the side of the vertical end 402 away from the fixed baffle 3. The end of the vertical end 402 away from the tightening roller 9 is an inclined guide part 404.

[0021] Furthermore, the fixed baffle 3 is provided with the same horizontal end and vertical end as the movable baffle 4, and is connected to the support body 1 through a pre-set connection hole at the horizontal end away from the movable baffle 4.

[0022] Please refer to the appendix carefully. Figure 2 In this embodiment, the support body 1 has a strip hole 101, the strip hole 101 is perpendicular to the fixed baffle 3, and the movable baffle 4 is attached to the support body 1 and is movably connected to the strip hole 101 through the connecting hole 403 by a fastening connector for position adjustment.

[0023] The fastening connectors are bolts and nuts.

[0024] Please refer to the appendix carefully. Figure 2 In this embodiment, an mounting plate 8 is provided on the side of the support body 1 away from the fixed baffle 3. A U-shaped hole is provided on the mounting plate 8. The movable baffle 4 is fixed or adjusted by the adjusting rod 405 passing through the U-shaped hole and combined with the locking nut.

[0025] As mentioned above, the U-shaped hole is designed to facilitate the downward movement of the movable baffle to fit against the support, thus making installation easier.

[0026] Please refer to the appendix carefully. Figure 3 In this embodiment, a parallel pressing roller 5 is also provided above the tightening roller 9. The pressing roller 5 is slidably mounted on the frame in the vertical direction through the slide seats 6 at both ends. An adjusting handwheel 7 is also provided above the frame. The connecting rod at one end of the adjusting handwheel 7 is rotatably connected to the slide seat 6.

[0027] As mentioned above, the pressure roller above the tightening roller is designed to press and convey the decorative paper, ensuring its smooth transport. The sliding installation of the pressure roller allows the head of the decorative paper to pass through the gap between the pressure roller and the tightening roller before processing, thus enabling automatic transport of the decorative paper.

[0028] In use, the installation position of the movable baffle 4 is first adjusted according to the width of the decorative paper. During adjustment, the locking nut and fastening connector are loosened in advance. Then, the movable baffle 4 is moved so that it moves in a straight line along the direction of the strip hole 101. After reaching the preset position, the locking nut is rotated on the adjusting rod 405 until it is close to the mounting plate 8. The fastening connector is then passed through the connecting hole 403 and the strip hole 101 to fix it, thus fixing the movable baffle 4.

[0029] After adjustment, the head of the decorative paper is pulled from the guide roller 2, then passes through the gap between the vertical end 402 of the fixed baffle 3 and the movable baffle 4 and is placed on the horizontal end 401. Then, the head of the decorative paper passes through the gap between the pressing roller 5 and the tightening roller 9, and is wound around the tightening roller 9 or guided by the tightening roller 9. After being combined with the external guide roller, the decorative paper is pulled and conveyed by the rotation of the external guide roller.
