At the same time, the winding device can also improve production efficiency, reduce manual intervention, and reduce production costs.

[0003] In order to meet the growing demand for product labels, printing paper processing manufacturers need to produce a large amount of product label printing paper. In the printing paper production process, winding is a key link. As an important auxiliary equipment, the winding device can help manufacturers process printing paper into standard rolls to facilitate subsequent cutting, packaging and distribution.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 2The utility model provides an embodiment: a winding device for processing product label printing paper, including a shell 1, a traction roller 2 is arranged on the inner wall of the shell 1, two sets of rotating shafts a5 are rotatably connected to the inner wall of the shell 1, a frame 3 is fixedly connected between the two sets of rotating shafts a5, a conveying roller 4 is rotatably connected to the outer wall of the frame 3, the rotating shaft a5 drives the frame 3 to rotate, thereby rotating the conveying roller 4, adjusting the angle and distance between the conveying roller 4 and the traction roller 2, thereby adjusting the tension of the paper during the traction process, so as to ensure that the paper is flat and will not wrinkle during the winding process, the inner wall of the rotating shaft a5 is elastically connected to the pull rod 7 through the reset spring 6, one end of the reset spring 6 is fixedly connected to the inner wall of the rotating shaft a5, and the other end of the reset spring 6 is fixedly connected to the inner end of the pull rod 7, and pulling the pull rod 7 outward can stretch the reset spring 6 to move outward At the same time, the elastic force generated by the deformation of the reset spring 6 gives the pull rod 7 an inward pulling force, prompting it to reset, and the outer wall of the pull rod 7 is provided with a rectangular protrusion structure, which can drive the rotating shaft a5 to rotate. The inner side of the pull rod 7 is fixedly connected to the limiting component, and the limiting component includes a limiting block 8. The outer wall of the shell 1 is provided with a plurality of groups of limiting grooves 9. The outer wall of the limiting block 8 is engaged with the inner wall of the limiting groove 9. During the outward movement of the pull rod 7, the limiting block 8 and the limiting groove 9 are released. At this time, the pull rod 7 can be rotated to make the rotating shaft a5 drive the skeleton 3 to rotate, thereby rotating the two groups of conveying rollers 4 and adjusting the distance between them and the traction roller 2. The inner wall of the shell 1 is fixedly connected to the support frame 10, and the back of the support frame 10 is welded with a motor 11. The output shaft of the motor 11 is fixedly connected to the rotating shaft b12, and the outer wall of the rotating shaft b12 is detachably connected to the winding roller 13.

[0031] Reference Figure 1 and Figure 3 The inner wall of the rotating shaft b12 is rotatably connected with a threaded rod 14, and the outer end of the threaded rod 14 is fixedly connected with a knob 15. Turning the knob 15 can drive the threaded rod 14 to rotate. The outer wall of the threaded rod 14 is threadedly connected with a block 16. The rotation of the threaded rod 14 can drive the block 16 to slide along the inner wall of the rotating shaft b12, and control the block 16 to move in the horizontal direction. The inner wall of the winding roller 13 is provided with a slide groove 18, and the inner wall of the slide groove 18 is slidably connected with the outer wall of the block 16. When the slide groove 18 is aligned with the block 16, the winding roller 13 can be removed or installed. After installation, the winding roller 13 needs to be rotated to stagger the slide groove 18 and the block 16. A slot 17 is provided on the inner wall of the winding roller 13, and the inner wall of the slot 17 is engaged with the outer wall of the block 16. When the winding roller 13 is rotated until the block 16 is aligned with the slot 17, the knob 15 can be rotated to make the block 16 snap into the slot 17, and the winding roller 13 is fixed on the rotating shaft b12.

[0032] Working principle: The product label printing paper is wound around the winding roller 13 along the traction roller 2 and the conveying roller 4, and then the tension of the paper is adjusted to make it more neat during the winding process. After the pull rod 7 is pulled outward to release the clamping block 8 from the limiting groove 9, the pull rod 7 is rotated to rotate the inner wall of the rectangular protrusion mechanism column shaft a5 on its outer wall with it, thereby changing the distance between the conveying roller 4 and the traction roller 2 and adjusting the tension of the paper. Then, the motor 11 is started to make the shaft b12 drive the winding roller 13 to rotate for winding. After winding, the knob 15 is turned to rotate the threaded rod 14, so that the clamping block 16 slides along the inner wall of the shaft b12 and releases the clamping groove 17. At this time, the winding roller 13 is rotated until the internal slide groove 18 is aligned with the clamping block 16, and the winding roller 13 is removed along the outer wall of the clamping block 16. Disassembly and assembly are relatively convenient, and no additional disassembly tools are required.
