[0026] Example

[0027] like Figure 1-4 As shown, the utility model proposes a tension feedback-based self-adhesive label unwinding adjustment device, comprising an unwinding device body 1 and a support baffle 2 mounted on the unwinding device body 1, a lifting handle 5 fixedly connected to the unwinding device body 1, and also comprising: an unwinding shaft 3 mounted on the support baffle 2, one end of the unwinding shaft 3 is fixedly connected to a rotating support shaft 4, a rotating clamping block 41 for clamping a telescopic button 32 retracted in the unwinding shaft 3 and moving outward from the unwinding shaft 3 is rotatably connected to the rotating support shaft 4, a groove 43 for tightly clamping the telescopic button 32 is provided at one end of the rotating clamping block 41 close to the telescopic button 32, a pair of pinching grooves 42 for clamping and pinching by fingers are provided on the rotating clamping block 41, and the function of the pinching grooves 42 is to increase friction when rotating the rotating clamping block 41 to avoid sliding between the fingers and the rotating clamping block 41. The unwinding shaft 3 is provided with a telescopic mechanism for clamping the self-adhesive label when unwinding and quickly releasing it when rewinding.

[0028] Further, the telescopic mechanism includes a plurality of telescopic support blocks 33 connected to the unwinding shaft 3 and arranged in a circumferential array. The telescopic support blocks 33 are provided with a slot 34 inside the unwinding shaft 3. When the main support rod 35 is inserted into the slot 34, the telescopic support block 33 can be retracted into the inside of the unwinding shaft 3. When the main support rod 35 is inserted into the middle of the telescopic support block 33, the telescopic support block 33 cannot be retracted into the inside of the unwinding shaft 3. The inside of the unwinding shaft 3 is movably connected with a main support rod 35 for resisting the plurality of telescopic support blocks 33 to be stretched outward from the unwinding shaft 3. One end of the main support rod 35 is fixedly connected with a secondary support rod 36, and the other end of the main support rod 35 is fixedly connected with a reset spring 38. The reset spring 38 is used to make the telescopic button 32 automatically protrude from the button slide groove 31. One end of the reset spring 38 away from the main support rod 35 is fixedly connected to the inner wall of the unwinding shaft 3, and one end of the unwinding shaft 3 is movably provided with a button mechanism for retracting the telescopic support block 33 into the unwinding shaft 3 after being pressed.

[0029] Furthermore, the button mechanism includes a button slot 31 provided on one end of the unwinding shaft 3, a telescopic button 32 is slidably connected inside the button slot 31, and an annular clamping plate 39 is fixedly sleeved on one end of the telescopic button 32 inside the unwinding shaft 3 for limiting the telescopic button 32 from escaping from the button slot 31. A push rod 37 for resisting the secondary support rod 36 is fixedly connected to one end of the telescopic button 32 inside the unwinding shaft 3, and one end of the push rod 37 in contact with the secondary support rod 36 is movably connected.

[0030] In this embodiment, when it is necessary to use a self-adhesive label unwinding adjustment device based on tension feedback, such as Figure 1 As shown. Press the telescopic button 32 inside the unwinding shaft 3, then rotate the rotating block 41 around the rotating support shaft 4, and then make the groove 43 on the rotating block 41 clamp the telescopic button 32. Install the paper core on the unwinding shaft 3, and then rotate the rotating block 41, as shown. Figure 3As shown, the main support rod 35 is subjected to the elastic thrust of the reset spring 38, so that the main support rod 35 pushes the secondary support rod 36, the push rod 37 and the telescopic button 32 to move outward from the unwinding shaft 3 in sequence. At this time, the main support rod 35 is disengaged from the card slot 34 on the multiple telescopic support blocks 33, and is released outward from the unwinding shaft 3 against the multiple telescopic support blocks 33, and finally the paper core is stuck, so that one end of the self-adhesive label can be pasted on the unwinding shaft 3, and then the unwinding device body 1 is started to rotate the unwinding shaft 3, and finally the self-adhesive label is wound on the paper core. When it is necessary to remove the self-adhesive label unwound on the paper core from the unwinding shaft 3, it is only necessary to press the telescopic button 32 inside the unwinding shaft 3, so that the multiple telescopic support blocks 33 are retracted into the unwinding shaft 3, and the self-adhesive label on the paper core on the unwinding shaft 3 can be quickly removed, which is convenient and easy to operate.
