Abstract
Description
Technical Field
[0001] The utility model relates to a rewinding device, in particular to an automatic rewinding device for self-adhesive labels. Background Art
[0002] The rewinding process in self-adhesive label production is a crucial step in the manufacturing process. During this process, the base and face papers, after undergoing silicone coating, gluing, and drying, are laminated at the laminating station and then rewound into large rolls. This step ensures the neatness and continuity of the self-adhesive material, facilitating subsequent processing and use. Precise execution of the rewinding process is crucial to the quality of the self-adhesive material.
[0003] Existing medium and large self-adhesive rewinding equipment requires manual pressure on the self-adhesive for winding during the label introduction process. Not only is there a risk of uneven pressure causing label deviation, but there is also a certain degree of danger and the safety of the workers' hands cannot be guaranteed. Utility Model Content
[0004] In order to overcome the disadvantages of uneven pressing and label deviation when manually pressing a label cylinder to roll the label, as well as certain risks, the utility model provides an automatic pressing and feeding self-adhesive label automatic rewinding device.
[0005] A self-adhesive label automatic rewinding device includes a base, a driving roller, a support plate, an electric push rod, an extrusion plate, a pressing bracket, a limit rod, a reset spring and a pressure roller. The driving roller is arranged on the side of the base. A plurality of guide rollers are arranged on the side of the base. The guide rollers are fixed by bolts. The support plate is fixed to the base and is located above the driving roller. The electric push rod is fixed to the end of the support plate. The telescopic end of the electric push rod is connected to the extrusion plate. The pressing bracket is slidably connected to the extrusion plate through the fixed limit rod. A reset spring is connected between the pressing bracket and the extrusion plate. The pressure roller is rotatably arranged in the pressing bracket.
[0006] As an improvement to the above scheme, it also includes a guide plate, a fixing screw, an internal thread block, an adjusting screw and a movable plate. The guide plate is fixed to the extrusion plate, the movable plate is slidably connected in the guide plate, the inner side surface of the guide plate is fixed with the internal thread block, the fixing screw is fixed to the limiting rod, the adjusting screw is threaded through the internal thread block, the lower end of the adjusting screw is limited and rotated in the movable plate, and the movable plate is fixed to the pressing bracket.
[0007] As an improvement to the above solution, an anti-skid pad is further included, which is arranged on the upper end of the adjusting screw.
[0008] As an improvement to the above solution, a positioning rod is further included, and the positioning rod is vertically fixed to the pressing bracket.
[0009] As an improvement of the above solution, a protective pad is further included, and the protective pad is sleeved on the outside of the pressure roller.
[0010] As an improvement to the above solution, a scale is further included. The scale is arranged on the side of the guide plate and can point to the height of the movable plate.
[0011] The beneficial effect is: the label end is fixed between the driving roller and the pressure roller, and then the driving roller is turned on. The driving roller will drive the label to be wound, and the pressure roller will evenly press the label roller to make it flat. As the diameter of the label roller increases, the electric push rod is used to control the distance between the pressure roller and the driving roller, so as to achieve continuous pressing of the label by the pressure roller. Compared with the existing manual pressing and guiding method, this device can press the label evenly and continuously through the pressure roller, and reduces the operational risks caused by manual participation.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Embodiment: A self-adhesive label automatic rewinding device, such as Figure 1-Figure 4As shown, it includes a base 1, a driving roller 2, a support plate 3, an electric push rod 4, an extrusion plate 5, a pressing bracket 6, a limit rod 7, a return spring 8 and a pressure roller 9. The driving roller 2 is arranged on the side of the base 1. A plurality of guide rollers are arranged on the side of the base 1. The guide rollers are fixed by bolts. The support plate 3 is fixed to the base 1 and is located above the driving roller 2. The electric push rod 4 is fixed to the end of the support plate 3. The telescopic end of the electric push rod 4 is connected to the extrusion plate 5. The pressing bracket 6 is slidably connected to the extrusion plate 5 through the fixed limit rod 7. A return spring 8 is connected between the pressing bracket 6 and the extrusion plate 5. The pressure roller 9 is rotatably arranged in the pressing bracket 6.
[0019] like Figure 3 As shown, it also includes a guide plate 10, a fixing screw 11, an internal thread block 12, an adjusting screw 13 and a movable plate 14. The guide plate 10 is fixed to the extrusion plate 5, and the movable plate 14 is slidably connected to the guide plate 10. The inner side of the guide plate 10 is fixed with the internal thread block 12, the fixing screw 11 is fixed to the limiting rod 7, the adjusting screw 13 is threadedly connected to the internal thread block 12, and the lower end of the adjusting screw 13 is limited and rotated in the movable plate 14, and the movable plate 14 is fixed to the pressing bracket 6.
[0020] like Figure 4 As shown, it also includes an anti-slip pad 15, a positioning rod 16, a protective pad 17 and a scale 18. The anti-slip pad 15 is arranged on the upper end of the adjusting screw 13, the positioning rod 16 is vertically fixed to the pressing bracket 6, and the positioning rod 16 can limit the side of the label roller so that the label remains flat during winding. The protective pad 17 is sleeved on the outside of the pressure roller 9, and the scale 18 is arranged on the side of the guide plate 10. The scale 18 can point to the height of the movable plate 14.
[0021] Working principle: Wind the label on the guide roller, then fix the end of the label between the driving roller 2 and the pressure roller 9, and then turn on the driving roller 2. The driving roller 2 will drive the label to wind, and the pressure roller 9 will evenly press the label roller to make it flat. As the diameter of the label roller increases, the electric push rod 4 controls the distance between the pressure roller 9 and the driving roller 2, so that the pressure roller 9 can continuously press the label. The height of the movable plate 14 can be adjusted according to the thickness of the label. By rotating the adjusting screw 13, the movable plate 14 can be driven to move up and down, and then the height of the pressing bracket 6 can be adjusted to adapt to labels of different thicknesses. During the up and down movement of the movable plate 14, the moving distance can be quantified by the scale 18.
