Description

Technical Field

[0001] This utility model relates to the field of self-adhesive paper production, and in particular to a winding device for self-adhesive paper production with a limiting structure. Background Technology

[0002] Self-adhesive paper production refers to a complete industrial process that uses paper, film, and other materials as base materials and processes such as coating, laminating, printing, and die-cutting to produce self-adhesive labels or packaging materials that can be pasted on demand. The final product must have stable adhesion, a flat appearance, and size specifications suitable for subsequent use scenarios. The winding device can simultaneously wind the continuously produced semi-finished and finished products into regular rolls, avoiding messy paper stacking and ensuring smooth operation of the production line.

[0003] The existing technology has the following drawbacks: In the winding process of self-adhesive paper production, some devices lack a limiting mechanism, which causes the paper to move irregularly laterally during continuous conveying and winding. This not only makes the edge of the wound material flared, requiring more waste to be removed during subsequent cutting to ensure that the specifications are met, thus greatly increasing the material loss rate, but also causes edge burrs, adhesive layer peeling, or even local tearing due to friction and collision between the paper and the edges of the equipment frame and rollers, directly reducing the product qualification rate. Therefore, a winding device for self-adhesive paper production with a limiting structure is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a winding device for producing self-adhesive paper with a limiting structure, which aims to improve the problem of easy deviation during winding in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winding device for producing self-adhesive paper with a limiting structure, comprising a winding machine, a guide roller group provided on the outer wall of the winding machine, a winding roller provided on the outer wall of the winding machine, an installation plate fixedly connected to the outer wall of the winding machine, a fixing plate fixedly connected to the left side wall of the installation plate, an adjusting screw rotatably connected through the inner wall of the fixing plate, a slider threadedly connected to the outer wall of the adjusting screw, a support plate hinged to the outer wall of the slider via a hinge rod, a fixing frame fixedly connected to the top of the support plate, a movable plate slidably connected to the inner wall of the fixing frame, a ball bearing rotatably connected to the outer wall of the movable plate, a positioning mechanism provided on the inner wall of the fixing plate, and an adjustment mechanism provided on the inner wall of the fixing frame; The positioning mechanism includes a positioning rod that passes through and is slidably connected to the inner wall of the fixed plate. The inner side wall of the positioning rod is elastically connected to the fixed plate through a return spring.

[0006] As a further description of the above technical solution: The adjustment mechanism includes a connecting screw that passes through and is threaded onto the inner wall of the fixed frame. A pressing plate is rotatably connected to the front end of the connecting screw. The outer wall of the pressing plate is elastically connected to the moving plate via a positioning spring. A guide rod is fixedly connected to the outer wall of the moving plate.

[0007] As a further description of the above technical solution: The guide rod passes through and is slidably connected to the inner wall of the fixed frame.

[0008] As a further description of the above technical solution: The outer wall of the extrusion plate is fixedly connected to one end of the positioning spring, the other end of the positioning spring is fixedly connected to the outer wall of the moving plate, and the extrusion plate is slidably connected to the inner wall of the fixed frame.

[0009] As a further description of the above technical solution: The extrusion plate is slidably connected to the outer wall of the guide rod.

[0010] As a further description of the above technical solution: The inner sidewall of the positioning rod is fixedly connected to one end of the return spring, and the other end of the return spring is fixedly connected to the top of the fixing plate. The positioning rod is inserted into the outer wall of the adjusting screw.

[0011] As a further description of the above technical solution: The outer wall of the slider is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the lower end of the support plate. The support plate is slidably connected to the inner wall of the mounting plate.

[0012] As a further description of the above technical solution: The slider is slidably connected to the inner wall of the fixed plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by adjusting the linkage of the screw, slider and hinge rod, different widths of self-adhesive paper can be quickly adapted. With the positioning and locking structure of the positioning rod and the return spring, the limit width deviation caused by equipment vibration can be effectively avoided, ensuring the limit accuracy and adaptation flexibility.

[0014] 2. In this utility model, by adjusting the compression of the positioning spring through the connecting screw, the resistance force of the ball against the paper can be precisely controlled. The rolling friction design of the ball reduces the wear of the paper during transport. At the same time, dynamic correction is achieved through elastic restoring force, ensuring that the self-adhesive paper enters the winding roller flat and improving the winding quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a self-adhesive paper production winding device with a limiting structure, including a winding machine 1. The outer wall of the winding machine 1 is provided with a guide roller group 2, which guides and supports the conveying path of the self-adhesive paper, ensuring that the paper remains flat and stable before winding, preventing paper deviation and wrinkling during transmission, providing a good paper posture for subsequent winding processes, and ensuring winding quality. (This is existing technology and will not be described in detail.) The outer wall of the winding machine 1 is provided with a winding roller 3, which is existing technology and rotates and winds the paper under motor control. An mounting plate 4 is fixedly connected to the outer wall of the winding machine 1. The mounting plate 4 mainly connects and supports components such as a fixing plate 5 and a support plate 9. A fixing plate 5 is fixedly connected to the left side wall of the mounting plate 4, and the inner wall of the fixing plate 5 is through and rotatably connected. An adjusting screw 6 is connected to the slider 7, which is threadedly connected to the outer wall of the adjusting screw 6. The middle of the slider 7 has a corresponding threaded groove of the adjusting screw 6, which allows the slider 7 to move along the groove. The outer wall of the slider 7 is hinged to a support plate 9 via a hinge rod 8. A fixed frame 10 is fixedly connected to the top of the support plate 9. A movable plate 11 is slidably connected to the inner wall of the fixed frame 10. The movable plate 11 mainly connects to the ball bearing 12, providing a rotation support point for the ball bearing 12. The outer wall of the movable plate 11 is rotatably connected to the ball bearing 12. The ball bearing 12 has a circular opening in the middle, which is slightly wider than the paper width to avoid scratching. When the self-adhesive paper is embedded in the opening and moves, it drives the ball bearing 12 to rotate, converting sliding friction into rolling friction, which greatly reduces the paper conveying resistance and wear. A positioning mechanism is provided on the inner wall of the fixed plate 5, and an adjusting mechanism is provided on the inner wall of the fixed frame 10.

[0019] The positioning mechanism includes a positioning rod 14, which is slidably connected to the inner wall of the fixed plate 5. The fixed plate 5 has a corresponding slot for the positioning rod 14, which allows the positioning rod 14 to move vertically along the slot. The inner side wall of the positioning rod 14 is elastically connected to the fixed plate 5 through a return spring 13.

[0020] Reference Figures 4-5The adjusting mechanism includes a connecting screw 15, which is threaded through and connected to the inner wall of the fixed frame 10. The fixed frame 10 has a threaded hole corresponding to the connecting screw 15, allowing the connecting screw 15 to move along the threaded hole. A pressing plate 16 is rotatably connected to the front end of the connecting screw 15. The outer wall of the pressing plate 16 is elastically connected to the moving plate 11 via a positioning spring 17. A guide rod 18 is fixedly connected to the outer wall of the moving plate 11, which is slidably connected through and connected to the inner wall of the fixed frame 10. The guide rod 18 can prevent the positioning spring 17 from being compressed during the compression process. The compression plate 16 deforms and guides the moving plate 11 to ensure that its position does not shift. The outer wall of the compression plate 16 is fixedly connected to one end of the positioning spring 17. When the compression plate 16 moves forward, it compresses the positioning spring 17, increasing the pressure on the moving plate 11 to move backward. When the compression plate 16 moves backward, the positioning spring 17 resets, and the pressure on the moving plate 11 to move backward decreases. The other end of the positioning spring 17 is fixedly connected to the outer wall of the moving plate 11. The compression plate 16 is slidably connected to the inner wall of the fixed frame 10 and the outer wall of the guide rod 18.

[0021] Reference Figures 2-4 The inner sidewall of the positioning rod 14 is fixedly connected to one end of the return spring 13. When the positioning rod 14 moves upward, it compresses the return spring 13. During reset, the elastic force of the return spring 13 carries the positioning rod 14 back to its original position. The other end of the return spring 13 is fixedly connected to the top of the fixing plate 5. The positioning rod 14 is inserted into the outer wall of the adjusting screw 6. The bottom end of the positioning rod 14 is round. When the round surface is compressed, it will cause the positioning rod 14 to move vertically. A groove corresponding to the positioning rod 14 is opened on the outer wall of the adjusting screw 6, allowing the positioning rod 14 to be inserted into the groove. Inside the opening, the outer wall of the slider 7 is hinged to one end of the hinge rod 8. Since the length of the hinge rod 8 is fixed, when the slider 7 moves to the left, it will cause the slider 7 to move along with one end of the hinge rod 8. The other end of the hinge rod 8 will pull the entire support plate 9 closer together. Conversely, when the slider 7 moves to the right, it will cause the slider 7 to move along with one end of the hinge rod 8. The hinge rod 8 will push the support plate 9 to separate from each other. The other end of the hinge rod 8 is hinged to the lower end of the support plate 9. The support plate 9 passes through and is slidably connected to the inner wall of the mounting plate 4. The slider 7 passes through and is slidably connected to the inner wall of the fixing plate 5.

[0022] Working principle: First, when adjusting the width of the self-adhesive paper, simply rotate the adjusting screw 6 on the fixed plate 5. The thread on its outer wall drives the slider 7 to move laterally along the groove of the fixed plate 5. Through the transmission action of the hinge rod 8, the two side support plates 9 move closer or further apart along the mounting plate 4, thereby adjusting the distance between the two sets of balls 12 to match the paper width. During the adjustment process, the positioning rod 14 is always pressed against the outer wall of the adjusting screw 6 under the elastic action of the return spring 13. When the target width is reached, the positioning rod 14 will be locked into the corresponding groove on the outer wall of the adjusting screw 6, thereby locking the adjusting screw 6 and preventing the equipment vibration during the winding process from causing the limit width to shift.

[0023] When elastic correction of the self-adhesive paper is required, simply rotate the connecting screw 15 on the fixed frame 10 to push the extrusion plate 16 to move along the guide rod 18. By changing the compression degree of the positioning spring 17, the elastic thrust of the moving plate 11 is adjusted, thereby controlling the resistance of the ball bearing 12 to the edge of the self-adhesive paper. After being guided by the guide roller group 2, the self-adhesive paper is embedded in the circular opening in the middle of the ball bearing 12 for conveying, driving the ball bearing 12 to rotate to convert sliding friction into rolling friction, reducing conveying resistance and wear. When the paper shifts laterally, the ball bearing 12 on the shifted side is squeezed by the paper and transmitted to the positioning spring 17 through the moving plate 11. The elastic restoring force of the positioning spring 17 pushes the ball bearing 12 in the opposite direction, pushing the paper back to the preset track. The guide rod 18 ensures the stable movement of the moving plate 11, and finally ensures that the paper enters the winding roller 3 flat to complete the winding.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
