[0002] Adhesive rewinding is a device used to rewind adhesive after production. It is an essential means of adhesive processing and production. It can rewind adhesive onto a pre-prepared paper tube for convenient and flexible use of adhesive later. Nowadays, adhesive rewinding mostly uses a motor to drive a rotating roller to rewind.

[0003] Chinese patent CN213140753U discloses a winding device for producing adhesive backing of insulating sheets. The device includes a base, with first side plates fixedly connected to the left and right sides of the upper end of the base. A rotating shaft is rotatably connected to the first side plates via bearings, and a threaded rod is internally threaded onto the rotating shaft. This invention inserts a winding drum between two sets of positioning plates from the top, inserts positioning blocks into positioning slots to position the winding drum, and rotates the threaded rod to screw it into the winding drum, thus fixing the winding drum between the two sets of positioning plates. This facilitates the installation and disassembly of the winding drum, improving work efficiency. The device can adjust the distance between the two sets of limiting plates according to the width of the adhesive backing of the insulating sheet, limiting the adhesive backing of the insulating sheet to prevent displacement during winding, thereby ensuring winding quality.

[0004] Existing technologies often have the following drawbacks: during the winding process of the adhesive backing, the adhesive backing is prone to loosening, which can lead to wrinkles and reduce the efficiency of winding the adhesive backing.

[0005] Therefore, this utility model provides an adhesive-backed winding and wrinkle-resistant device. Utility Model Content

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: an adhesive-backed winding anti-wrinkle device, including a base 1 and a paper tube 4. A side plate is fixedly installed on the upper surface of the base 1, and a motor 3 is fixedly installed on the surface of the side plate. An adhesive roll 5 is wound around the side wall of the paper tube 4. An anti-wrinkle structure 6 is provided on the surface of the side plate, and a support structure 7 is provided at the output end of the motor 3.

[0030] The following section will explain the specific design and function of its anti-wrinkle structure 6 and support structure 7.

[0031] Reference Figure 1-4 As shown in this embodiment: the anti-wrinkle structure 6 includes a connecting strip 604 fixedly connected to the upper surface of the side plate. The connecting strip 604 has an L-shaped structure, and two limiting pins 605 are slidably connected inside the connecting strip 604. The lower ends of the two limiting pins 605 are fixedly connected to a pressure plate 602, and the upper ends of the two limiting pins 605 are fixedly connected to a counterweight box 601. By setting the anti-wrinkle structure 6, the pressure applied during the adhesive roll-up process is facilitated, avoiding wrinkles after the adhesive roll 5 is rolled up, and improving the efficiency of the adhesive roll-up. A water inlet 606 is fixedly connected to the upper surface of the counterweight box 601, and a water inlet plug 608 is threadedly connected to the inner side of the water inlet 606. A water outlet 607 is fixedly connected to the lower surface of the counterweight box 601, and a water outlet plug 609 is threadedly connected to the inner side of the water outlet 607. Opening the drain plug 609 allows for the discharge of water from the outlet 607, facilitating the subsequent movement and handling of the anti-wrinkle device. A rotating rod 603 is rotatably connected to the inner side of the pressure plate 602. The rotating rod 603 on the inner side of the pressure plate 602 can roll as the diameter of the adhesive roll 5 increases, preventing sliding friction between the pressure plate 602 and the adhesive surface and reducing material damage. A support strip 610 is slidably connected to the side wall of the connecting strip 604. After raising the counterweight box 601 to a certain height, sliding the support strip 610 on the connecting strip 604 allows it to slide below the counterweight box 601, providing flexible support for the raised counterweight box 601 and facilitating the subsequent fixing of the paper tube 4.

[0032] Reference Figure 1-3 As shown, specifically, the support structure 7 includes a screw 75 fixedly connected to the output end of the motor 3. A circular plate 71 is fixedly connected to the other end of the screw 75. Four grooves are formed on the surface of the circular plate 71. A slider 76 is slidably connected to the inner wall of each groove. A support rod 72 is fixedly connected inside the slider 76. A push block 74 is threadedly connected to the side wall of the screw 75. The end of the push block 74 near the circular plate 71 has a frustum-shaped structure. By setting up the support structure 7, the flexible support and fixing of the paper tube 4 is facilitated, thus facilitating the subsequent winding of the adhesive backing on the outer side of the paper tube 4. Several rubber blocks 73 are glued to the side wall of the support rod 72. The rubber blocks 73 on the side wall of the support rod 72 further enhance the fixing friction through elastic compression. Anti-slip textures are provided on the side of the push block 74 away from the circular plate 71. The anti-slip textures on the side of the push block 74 away from the circular plate 71 facilitate manual rotation operation.

[0033] Working principle: Upon opening the water injection plug 608, water is injected into the counterweight box 601 through the water injection port 606, increasing its weight. This weight is then transferred to the pressure plate 602 via the limit pin 605, ensuring the pressure plate 602 remains in contact with the adhesive roll 5 surface. As the adhesive roll 5 is wound onto the paper tube 4, the pressure of the pressure plate 602 smooths out gaps between the adhesive layers, preventing wrinkles caused by looseness. The rotating rod 603 inside the pressure plate 602 rolls as the diameter of the adhesive roll 5 increases, preventing sliding friction between the pressure plate 602 and the adhesive surface and reducing material damage. Meanwhile, the support bar 610 on the connecting bar 604 can provide temporary support when the counterweight box 601 needs to be lifted. By sliding the support bar 610 to the bottom of the counterweight box 601, flexible positioning can be achieved. Opening the water outlet plug 609 can realize the discharge of water at the water outlet 607, which facilitates the subsequent movement and handling of the anti-wrinkle device. By setting the anti-wrinkle structure 6, it is convenient to apply pressure during the adhesive winding process, avoiding the phenomenon of wrinkles after the adhesive roll 5 is wound, and improving the efficiency of the adhesive winding.

[0034] After the paper tube 4 is placed on the outside of the four support rods 72, the push block 74 is rotated to move along the screw 75 axially. The end of the push block 74 near the circular plate 71 has a frustum-shaped structure. When moving, it can push the slider 76 to expand outward along the groove of the circular plate 71, which will drive the support rods 72 to tighten the inner wall of the paper tube 4. The rubber block 73 on the side wall of the support rod 72 further enhances the fixing friction through elastic compression, ensuring that the paper tube 4 does not shake during the winding process. This realizes the quick support and fixing of the paper tube 4, and further facilitates the winding of the adhesive on the back of the paper tube 4. The side of the push block 74 away from the circular plate 71 is provided with anti-slip texture, which is convenient for manual rotation operation. By setting the support structure 7, the flexible support and fixing of the paper tube 4 is facilitated, which facilitates the subsequent winding of the adhesive on the outside of the paper tube 4.
