Description

Technical Field

[0001] This application belongs to the field of embossing roller technology, and particularly relates to a paper printing embossing roller. Background Technology

[0002] An embossing roller is a cylindrical tool used to press various patterns, designs, or textures onto the surface of materials such as paper, leather, or plastic film. The surface of the embossing roller has raised or recessed patterns made by engraving or chemical etching. By applying a certain pressure to the material, permanent or semi-permanent indentations are created on the surface of materials such as paper, forming the desired pattern effect.

[0003] The existing utility model with authorization announcement number CN220763729U discloses a tissue embossing roller. Through the cooperative arrangement of an embossing mold cylinder, an installation rod, an installation component, and a fixing component, when the embossing mold cylinder needs to be installed, the installation rod is first inserted into the inner side of the embossing mold cylinder, and then the embossing mold cylinder and the installation rod are connected by the installation component. Then, the fixing component is rotated, thereby fixing and locking the connection of the installation rod, thus completing the installation and replacement of the embossing mold cylinder. This avoids the need to use screws to install and fix the embossing mold cylinder, which would make the replacement more cumbersome and reduce work efficiency.

[0004] While the above technical solution facilitates the installation and replacement of the embossing die cylinder and improves the replacement efficiency, it does not take into account the possibility of wrinkles or embossing failures due to paper instability during embossing. It lacks a stable structure to improve the stability of paper embossing, which causes wrinkles to occur in continuous long sheets of paper during embossing due to unstable paper feeding, thus affecting the final effect of paper embossing.

[0005] To address this issue, we propose a paper printing embossing roller. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that continuous long paper will wrinkle due to unstable paper feeding during embossing, thus affecting the final effect of paper embossing, and proposes a paper printing embossing roller.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A paper printing embossing roller includes two support plates. An auxiliary bearing is fixedly connected to the inner wall of each support plate. A rotating rod is fixedly connected to the inner ring of both auxiliary bearings. A smooth auxiliary cylinder is fixedly connected to the outer surface of the rotating rod. A fixed plate is fixedly connected to the front of each support plate. A smooth clamp and a printing roller are arranged on the side of the two fixed plates that are close to each other. A movable plate is arranged on the side of the two support plates that are close to each other. Slider blocks are fixedly connected to both sides of the movable plate. Three sliding rods are slidably connected inside the movable plate. A semi-cylindrical top block is fixedly connected to the bottom end of the three sliding rods. A limit plate is fixedly connected to the top end of each sliding rod. A return spring is sleeved on the outer surface of each sliding rod. A guide rod is fixedly connected to the inner wall of each support plate.

[0009] Preferably, the inner wall of each fixed plate is rotatably connected to the outer surface of the smooth clamp and the outer surface of the printing roller, the interior of each slider is slidably connected to the outer surface of the guide rod, the two ends of each return spring are fixedly connected to the bottom surface of the moving plate and the upper surface of the semi-cylindrical top block, and two mounting plates are fixedly connected to the side of each of the two support plates that are far apart from each other, and two mounting holes are opened on the upper surface of each mounting plate.

[0010] Preferably, a handle is fixedly connected to the side of each of the two sliders that are far apart from each other, and an anti-slip sleeve is fixedly connected to the outer surface of each handle.

[0011] Preferably, each of the support plates is provided with a connecting plate on its outer side, and two positioning posts are fixedly connected to the side of the two connecting plates that are close to each other.

[0012] Preferably, each of the support plates has a plurality of identical positioning holes on its outer surface, and the outer surface of each positioning post is in contact with the inner wall of the positioning hole.

[0013] Preferably, each of the two connecting plates has a locking block fixedly connected to one side of each other, the bottom surface of each locking block is in contact with the upper surface of the slider, and the inner wall of each locking block is in contact with the outer surface of the guide rod.

[0014] In summary, the technical effects and advantages of this application are as follows:

[0015] By employing a support plate, guide rod, slider, and movable plate, the slider can move up and down along the outer surface of the guide rod, thereby driving the movable plate and the semi-cylindrical top block to move up and down. This adjusts the distance between the movable plate and the smooth auxiliary cylinder according to the thickness of the paper on the smooth auxiliary cylinder. The printing roller can be connected to an external power mechanism, allowing it to work with the smooth clamp to print on the paper between them. Furthermore, by employing a movable plate, slider, limit plate, semi-cylindrical top block, and return spring, the movable plate and semi-cylindrical top block compress the return spring, which in turn generates a reverse rebound force on the semi-cylindrical top block. This allows the semi-cylindrical top block to clamp the paper to be printed with the smooth auxiliary cylinder, increasing the stability of the paper. This avoids the problem of continuous long sheets of paper wrinkling due to unstable paper transport during embossing due to the lack of a stable structure that improves the stability of paper embossing, thus affecting the final effect of paper embossing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A paper printing embossing roller includes two support plates 1. Each support plate 1 has an auxiliary bearing 3 fixedly connected to its inner wall. The inner rings of the two auxiliary bearings 3 are fixedly connected to a rotating rod 2. A smooth auxiliary cylinder 4 is fixedly connected to the outer surface of the rotating rod 2. Two mounting plates 6 are fixedly connected to the two support plates 1 on their opposite sides. Each mounting plate 6 has two mounting holes 7 on its upper surface. By providing mounting plates 6 and mounting holes 7, external bolts and mounting docking structures can be used to dock the rollers, thereby fixing the two support plates 1 and, consequently, the smooth auxiliary cylinder 4 and other structures.

[0023] Each support plate 1 has a fixed plate 5 fixedly connected to its front side. The two fixed plates 5 are arranged together on the side close to each other, with a smooth clamp 14 and a printing roller 15. The inner wall of each fixed plate 5 is rotatably connected to the outer surface of the smooth clamp 14 and the outer surface of the printing roller 15, respectively. The two support plates 1 are arranged together on the side close to each other, with a moving plate 16. Each support plate 1 has a connecting plate 10 on its outer side. The two connecting plates 10 are fixedly connected to two positioning posts 11 on the side close to each other. By setting the connecting plate 10 and the positioning posts 11, the height of the slider 21 can be limited in conjunction with other positioning structures, thus playing an auxiliary limiting role.

[0024] Slider 21 is fixedly connected to both sides of the movable plate 16. Three slide rods 17 are slidably connected inside the movable plate 16. Several identical positioning holes 12 are opened on the outer surface of each support plate 1. The outer surface of each positioning post 11 is in contact with the inner wall of the positioning hole 12. By setting the positioning hole 12, it can dock with the positioning post 11, which plays the role of fixing the height of the connecting plate 10 and other limiting structures. The spacing between the upper and lower positioning holes 12 can be adjusted according to the actual paper thickness during actual use.

[0025] The bottom ends of the three slide rods 17 are all fixedly connected to a semi-cylindrical top block 19. The top of each slide rod 17 is fixedly connected to a limit plate 18. The two sliders 21 are fixedly connected to a handle 8 on their opposite sides. The outer surface of each handle 8 is fixedly connected to an anti-slip sleeve 9. By setting the handle 8, it is convenient to raise or lower the slider 21, thereby facilitating the adjustment of the initial distance between the semi-cylindrical top block 19 and the smooth auxiliary cylinder 4.

[0026] Each slide bar 17 has a return spring 20 fitted on its outer surface. The two ends of each return spring 20 are fixedly connected to the bottom surface of the moving plate 16 and the upper surface of the semi-cylindrical top block 19, respectively. Each support plate 1 has a guide rod 22 fixedly connected to its inner wall. The interior of each slider 21 is slidably connected to the outer surface of the guide rod 22. Each of the two connecting plates 10 has a locking block 13 fixedly connected to one side of each other. The bottom surface of each locking block 13 is in contact with the upper surface of the slider 21, and the inner wall of each locking block 13 is in contact with the outer surface of the guide rod 22. By setting the locking block 13, the upper surface of the slider 21 can be blocked, which can limit the maximum height of the slider 21 and the initial distance between the moving plate 16 and the smooth auxiliary cylinder 4.

[0027] The working principle of this utility model is as follows: In use, the mounting plate 6 and mounting hole 7 are fixedly connected with the mounting docking structure in the continuous paper printing environment using external mounting bolts. Then, the printing roller 15 is connected with the external drive structure. According to the thickness of the paper to be printed, the slider 21 is adjusted by holding the anti-slip sleeve 9 on the handle 8 and sliding up and down along the guide rod 22 until the semi-cylindrical top block 19 and the smooth auxiliary cylinder 4 just slightly tighten and clamp the paper. At the same time, the moving plate 16 and the semi-cylindrical top block 19 compress the return spring 20 to a certain extent. The distance between the upper and lower positioning holes 12 can be adjusted by drilling according to the actual paper thickness during use. Then, the locking block 13 on the connecting plate 10 is inserted into the support plate 1 above the slider 21. Inside, the positioning pin 11 on the connecting plate 10 is positioned with the positioning hole 12. Then, the continuous paper to be printed is placed between the smooth auxiliary cylinder 4 and the semi-cylindrical top block 19 and then fed between the smooth clamping cylinder 14 and the printing roller body 15. Then, the printing roller body 15 is driven to rotate by the external drive mechanism. During this period, the rotating rod 2 rotates in the inner ring of the auxiliary bearing 3. At the same time, the semi-cylindrical top block 19 and the smooth auxiliary cylinder 4 flexibly clamp the paper, which greatly increases the stability of the continuous paper in the printing and conveying process. The design of the entire paper printing embossing roller effectively solves the problem that the continuous long paper will wrinkle due to unstable paper conveying when it is embossed due to the lack of a stable structure that can improve the stability of paper embossing, thus affecting the final effect of paper embossing.
