[0001] This utility model relates to the technical field of abrasive cloth winding devices, specifically an abrasive cloth winding device that facilitates tension adjustment. Background Technology

[0002] Abrasive cloth winding devices are automated or semi-automatic equipment used to wind abrasive cloth materials into rolls. They are widely used in the abrasive and grinding tool manufacturing industry to ensure that the abrasive cloth rolls are neat and secure, easy to store, transport and use in subsequent processing, and can improve the efficiency and quality of abrasive cloth winding while reducing the intensity of manual operation.

[0003] The tension-adjustable abrasive cloth winding device is an abrasive cloth winding equipment that optimizes tension control. Its core is equipped with a high-precision tension adjustment system, which usually includes a pressure sensor and a motor. It can adjust the winding tension in a timely manner to ensure stable tension. It is suitable for abrasive cloths of different thicknesses and materials, avoiding breakage due to excessive tightness or wrinkles due to excessive looseness, thereby improving winding quality and adaptability.

[0004] Existing abrasive cloth winding devices that facilitate tension adjustment still have the following problems: it is inconvenient to disassemble the take-up roller. Usually, after the take-up roller has finished collecting abrasive cloth, it needs to be replaced so that the device can continue to work. Usually, a screwdriver is needed to remove the screws, but when using a screwdriver, it is easy to puncture the abrasive cloth or scratch the device. In order to address the above problems, an abrasive cloth winding device that facilitates tension adjustment is proposed. Utility Model Content

[0036] Combination Figures 1-2 The L-shaped frame 5 has a rotating assembly at its top center rear end. The rotating assembly includes a worm gear 7, the bottom of which is rotatably connected to the L-shaped frame 5. A threaded rod 9 is threaded through and connected to the middle of the worm gear 7.

The worm 10 is meshed with the worm gear 7. The worm 10 is mounted by the mounting plate 13. Rotation of the worm 10 can drive the worm gear 7 to rotate. A turntable 11 is fixedly connected to one side of the worm 10. The turntable 11 drives the worm 10 to rotate. A U-shaped plate 6 is fixedly connected to the bottom of the threaded rod 9. The threaded rod 9 drives the U-shaped plate 6 to move up and down.

[0037] Working principle: When the brake motor 21 is turned on, its output rotates, driving the rotating block 18 and the take-up roller 19 to rotate, thus winding the abrasive cloth. When the tension is too high, the turntable 11 drives the worm gear 10 to rotate, which in turn drives the worm wheel 7 to rotate. Under the action of the thread, the threaded rod 9 moves upward, thereby moving the housing 4 and the pressure sensor 26 upward. At this time, the included angle of the abrasive cloth increases, and the tension decreases. When the tension is too low, causing the winding to be insufficiently taut, the rotation reverses. By moving the disc 11 downwards, the housing 4 and pressure sensor 26 can be moved downwards. At this time, the included angle of the abrasive cloth becomes smaller, and the tension increases. When the take-up roller 19 is full of abrasive cloth, it needs to be quickly disassembled. Pull the pull rod 22 through the pull plate 20, and the pull rod 22 pulls the pressure plate 23. The pressure plate 23 presses the spring 24 and moves along the inner wall of the slide groove 25. After the pull rod 22 disengages from the insert block 15, the second upright plate 14 can be removed, and then the take-up roller 19 can be removed, thus completing the quick disassembly of the take-up roller 19.
