A limiting sleeve 503 is slidably connected to the inner wall of the sliding cavity 504. An abutment rod 502 is fixedly connected to the inner wall of the limiting sleeve 503. A spring 505 is fixedly connected to the top of the limiting sleeve 503, and the other end of the spring 505 is fixedly connected to the inner wall of the sliding cavity 504. One end of the abutment rod 502 passes through the top of the sliding cavity 504 and is fixedly connected to a pull rod 501. The other end of the abutment rod 502 passes through the sliding cavity 504. The bottom of the label is slidably connected inside the placement groove 4. In use, first pull up the pull rod 501 of the clamping component 5, which will drive the abutment rod 502 away from the bottom of the inner wall of the placement groove 4. The function of the limiting sleeve 503 fixedly connected to the outer wall of the abutment rod 502 is to prevent the abutment rod 502 from being completely pulled out of the sliding cavity 504. Place one end of the thermal paper label body 6 into the placement groove 4, and then release the pull rod 501. Under the force of the spring 505, the thermal paper label body 6 is clamped and fixed, preventing it from falling off when the thermal paper label body 6 is wound.

[0025] A thermal paper label body 6 is movably connected to the inner wall of the placement slot 4. The thermal paper label body 6 includes a bottom paper layer 601 movably connected to the inner wall of the placement slot 4, and the inner surface of the bottom paper layer 601 is movably connected to the outer wall of four connecting plates 3. The arrangement of multiple connecting plates 3 can wind the thermal paper label body 6. A thermal paper layer 602 is provided on the top of the bottom paper layer 601. The thermal paper layer 602 is located at the top of the inner wall of the placement slot 4 and abuts against one end of the abutment rod 502. A release layer is provided at the bottom of the bottom paper layer 601. The release layer includes an adhesive layer to facilitate adhesion during use. A protective layer is provided on the adhesive layer to protect the adhesive from contamination until the thermal paper label body 6 is used.

[0026] A mounting cavity 8 is provided inside the support column 1 near its front end. The mounting cavity 8 is used to install the main gear 703 and the auxiliary gear 704. A tension adjustment assembly 7 is provided at the front end of the support column 1. The tension adjustment assembly 7 includes a connecting column 702 that is rotatably connected to the front of the support column 1. A rotating block 701 is fixedly connected to the end of the connecting column 702 away from the support column 1. The main gear 703 is installed on the outer wall of the inner cavity of the mounting cavity 8. Four auxiliary gears 704 are meshed in a circular array on the outer wall of the main gear 703. A connecting shaft 705 is installed on the inner wall of each auxiliary gear 704. The outer wall of the connecting shaft 705 is rotatably connected to the back of the inner cavity of the mounting cavity 8. Adjusting gears 706 are symmetrically installed on the outer wall of the connecting shaft 705. The adjusting gears 706 are located inside the sliding grooves provided on the outer wall of the connecting rod 2. A toothed plate 707 is meshed on the outer wall of the wheel 706. One side of the outer wall of the toothed plate 707 is located in a slot on the outer wall of the connecting rod 2 in the slide groove. The worker can rotate the rotating block 701 as needed to drive the connecting column 702 and the main gear 703 installed on the outer wall to rotate. The outer wall of the main gear 703 is meshed with a secondary gear 704. A connecting shaft 705 is installed on the inner wall of the secondary gear 704. Through the toothed plate 707 meshed with the outer wall of the adjusting gear 706 installed on the outer wall of the connecting shaft 705, multiple connecting rods 2 can drive the connecting plate 3 fixed at one end to move outward or inward, thereby adjusting the tension of the support column 1 during winding, making the winding more compact. After winding, the connecting plate 3 can also be moved inward by adjusting the tension adjusting component 7, making it easy to remove the thermal paper label body 6 after winding.

[0027] One end of the back of the support column 1 is connected to a support plate 9 by a thread. The diameter of the support plate 9 is larger than the outer diameter of the four connecting plates 3. The support plate 9 can limit the movement at the beginning of the winding and increase stability.

[0028] Working principle: In use, first pull up the lever 501 of the clamping component 5, which moves the abutment lever 502 away from the bottom of the inner wall of the placement groove 4. The limiting sleeve 503 fixedly connected to the outer wall of the abutment lever 502 prevents the abutment lever 502 from being completely pulled out of the sliding cavity 504. Place one end of the thermal paper label body 6 into the placement groove 4, and then release the lever 501. Under the force of the spring 505, the thermal paper label body 6 is clamped and fixed, preventing it from falling off during winding. The bottom of the bottom paper layer 601 is provided with a release layer, which includes an adhesive layer to facilitate adhesion during use. A protective layer is provided on the adhesive layer to protect the adhesive from contamination until the thermal paper label body 6 is used. At the same time, the tension adjustment component 7 allows the worker to... Rotating the rotating block 701 as needed drives the connecting column 702 and the main gear 703 mounted on the outer wall to rotate. The outer wall of the main gear 703 is meshed with a secondary gear 704. The inner wall of the secondary gear 704 is equipped with a connecting shaft 705. Through the toothed plate 707 meshing with the outer wall of the adjusting gear 706 mounted on the outer wall of the connecting shaft 705, multiple connecting rods 2 can drive the connecting plate 3, which is fixedly connected at one end, to move outward or inward. This allows for tension adjustment during the winding of the support column 1, making the winding more compact. After winding, the connecting plate 3 can also be moved inward by adjusting the tension adjusting component 7, making it easy to remove the thermal paper label body 6 after winding. The support plate 9, which is threaded to one end of the back of the support column 1, serves to limit the initial winding and increase stability.
