[0027] Example 1:
[0028] like Figures 1 to 5 As shown in the figure, a rewinding machine provided by this utility model embodiment includes a main body 1. A control panel 11 is fixedly installed on the front outer wall of the main body 1. A display screen 12 is connected to the control panel 11. A take-up reel 15 and an unwind reel 16 are movably connected to the upper end of the main body 1, and a mounting plate 13 is fixedly connected to it. A touch sensor 14 and a metering component 2 are connected to the upper end of the mounting plate 13, as well as a guide component 3 for guiding self-adhesive labels.

The drive unit drives the take-up reel 15 and unwind reel 16 to rotate. The guide component 3 guides the self-adhesive labels, making it easy to guide the self-adhesive labels on the unwind reel 16 to the take-up reel 15 to realize the rewinding operation. During the rotation of the take-up reel 15, the protrusion 151 rotates and contacts the metering component 2, which in turn contacts the touch sensor 14. Under the action of the force, the touch sensor 14 realizes the metering and displays it on the display screen 12 for easy viewing by the operator. This facilitates the control of the number of rewinding turns, thereby controlling the weight of the rewound self-adhesive labels and ensuring that the weight of the rewound self-adhesive labels is consistent.
[0029] like Figures 1 to 2 As shown, the guide assembly 3 includes a first guide shaft 32 and a second guide shaft 34 fixedly connected to the mounting plate 13, and a rotating drum 33 movably connected to the mounting plate 13. The rotating drum 33 is located at the front end of the first guide shaft 32 and the second guide shaft 34 and is arranged in a triangular shape. A limiting cover plate 31 is provided at the upper end of the rotating drum 33, the first guide shaft 32 and the second guide shaft 34. The limiting cover plate 31 is fixedly installed at the upper end of the rotating drum 33, the first guide shaft 32 and the second guide shaft 34 by a screw. A movable knob 321 is sleeved on the outer wall of the first guide shaft 32 and the second guide shaft 34. The first guide shaft 32 and the second guide shaft 34 facilitate the guidance of the self-adhesive, and the rotating drum 33 facilitates the flatness of the self-adhesive surface during the rewinding process.
[0030] like Figure 2 As shown, a protrusion 151 is fixedly connected to the outer wall of the winding reel 15; through the protrusion 151, during the rotation of the winding reel 15, the protrusion 151 is driven to rotate and contact the metering device, thereby driving the metering device to contact the touch sensor 14 to achieve metering.

A positioning shaft 231 is provided at the upper end of the connecting rod 23. The positioning shaft 231 passes through the connecting rod 23 and the base 21 in sequence and is connected to the movable rod 24. The connecting rod 23 is fixedly connected to the movable rod 24 through the positioning shaft 231. A fixed shaft 233 and a second spring buckle 232 are fixedly connected to the outer wall of the upper end of the connecting rod 23. A push rod 22 is provided at the front end of the connecting rod 23. A limiting block 221 and a push block 222 are integrally formed at the front and rear ends of the push rod 22, respectively.

The first spring buckle 223 has a return spring 25 connected to its outer wall, and the other end of the return spring 25 is connected to the second spring buckle 232. The movable rod 24 is arranged in a T-shape, and the right side of the movable rod 24 is arranged in a semi-circular shape. As the take-up reel 15 rotates, the protrusion 151 rotates and contacts the movable rod 24. During the rotation of the movable rod 24 through the protrusion 151, the movable rod 24 can rotate around the positioning shaft 231 as the center point, which facilitates the contact of the movable rod 24 with the touch sensor 14 on the right side. The contact force of the touch sensor 14 is used to count the number of rotations of the take-up reel 15. During the rotation of the movable rod 24, the positioning shaft 231 drives the connecting rod 23 to rotate. The connecting rod 23 is limited by the cooperation of the fixed shaft 233 and the push block 222. The return spring 25 is used to facilitate the connection rod 23 to drive the movable rod 24 to return to its original position, thereby realizing the counting of the number of rewinding turns during the rewinding process of the self-adhesive.
[0032] like Figure 5As shown, the lower end of the main body 1 is connected to multiple buffer components 4; each buffer component 4 includes a placement tray 41 in contact with the ground, an outer cylinder 42 fixedly connected to the upper end of the placement tray 41, an inner rod 43 movably connected inside the outer cylinder 42, the upper end of the inner rod 43 extending out of the outer cylinder 42 and fixedly connected to the main body 1; a buffer block 44 is fixedly connected to one end of the inner rod 43 inside the outer cylinder 42, a buffer spring 45 is connected to the lower end of the buffer block 44, and the other end of the buffer spring 45 is connected to the inner wall of the outer cylinder 42; the lower outer wall of the placement tray 41 is provided with an inwardly recessed arc-shaped groove 412; the placement tray An anti-slip pad 411 is fixedly connected to the lower outer wall of 41. The anti-slip pad 411 is circular and surrounds the outside of the arc-shaped groove 412. The placement plate 41 with the arc-shaped groove 412 facilitates the placement plate 41 to adhere to the ground, improving the stability of the main body 1. The anti-slip pad 411 prevents the main body 1 from moving during use. The force generated during the use of the main body 1 moves into the outer cylinder 42 through the inner rod 43, causing the buffer block 44 to move inside the outer cylinder 42 and compress the buffer spring 45, thereby buffering the main body 1 and further improving the stability of the main body 1.
[0033] Working principle of Example 1:
[0034] In use, the self-adhesive label to be rewound is connected to the unwinding reel 16, and the sleeve to be wound is connected to the take-up reel 15. The self-adhesive label is pulled apart, and the other end is connected to the rotating drum 33 on the take-up reel 15. During the pulling apart process, it contacts the first guide shaft 32, the rotating drum 33 and the second guide shaft 34 to prevent the self-adhesive label from wrinkling during the rewinding process. The drive device built into the main body 1 is started to drive the take-up reel 15 and the unwinding reel 16 to rotate. The guide component 3 guides the self-adhesive label, making it easy to guide the self-adhesive label on the unwinding reel 16 to the take-up reel 15 to realize the rewinding operation. During the rotation of the take-up reel 15, the protrusion 151 is driven to rotate and contact the metering component 2, which in turn drives the metering component 2 to contact the touch sensor 14. Under the action of the force, the touch sensor 14 realizes the metering and displays it on the display screen 12 for easy viewing by the operator. This makes it easy to control the number of rewinding turns, thereby controlling the weight of the rewound self-adhesive label and achieving consistent weight of the rewound self-adhesive label products.
