Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, and in particular to a winding mechanism for self-adhesive labels. Background Technology

[0002] Self-adhesive labels are composite papers made of paper, film, or special materials as the face stock, coated with adhesive on the back, and protected by silicone paper as the backing.

[0003] Self-adhesive labels typically rely on roll form during production to improve efficiency, reduce waste, and save storage space. However, currently, in winding machines, operators usually manually position the roll outside the air shaft. This manual positioning method can easily cause the roll to become skewed, resulting in an overall skewed roll of self-adhesive paper that affects product quality.

[0004] In addition, when the rewinding is completed and the paper is unloaded, the current unloading method is generally that when the expansion block in the air shaft retracts, the staff directly pushes the self-adhesive roll to unload it. During this process, the self-adhesive roll is also prone to skewing. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a winding mechanism for self-adhesive labels, thereby solving the problems mentioned in the background section.

[0006] This utility model provides the following technical solution: a winding mechanism for self-adhesive labels, including a frame, a winding roller rotatably connected to the side of the frame, and a motor for driving the winding roller to rotate inside the frame;

[0007] The take-up roller is equipped with a paper tube positioning assembly, which includes a slide cylinder that is slidably connected to the take-up roller from left to right. One side of the slide cylinder is integrally formed with an abutment plate. A first slide groove is also provided in the curved surface of the take-up roller. A first slider is slidably connected in the first slide groove. A threaded shaft is rotatably connected in the slide cylinder, and the threaded shaft is threadedly connected in the first slider.

[0008] Preferably, the end of the threaded shaft is equipped with a knob.

[0009] Preferably, the take-up roller is also slidably connected to a pusher plate on the left and right, and the roller also includes a locking component for locking the relative position of the pusher plate and the abutment plate.

[0010] Preferably, the locking component includes two spring grooves symmetrically distributed on the left side of the push plate, a movable block is slidably connected in the spring groove, a hook plate is integrally formed on the left end of the movable block extending outside the spring groove, a control key is provided on the side of the movable block extending outward through the curved surface of the push plate, and a spring is installed on the side of the movable block opposite to the control key.

[0011] The receiving plate is provided with a through groove for accommodating the hook plate.

[0012] Preferably, the end of the control key is equipped with an arc-shaped plate.

[0013] Preferably, the winding roller has multiple second-order grooves at equal angles on its curved surface, and the pusher plate has a second-order slider inserted into the second-order groove on its inner curved surface.

[0014] The outer curved surface of the push plate on the right side of the spring groove is provided with an annular groove.

[0015] Preferably, the take-up roller is either a mechanical expansion shaft or a pneumatic expansion shaft, and the ejectable protrusion inside the take-up roller is axially misaligned with the second slide groove.

[0016] This utility model provides a winding mechanism for self-adhesive labels, which has the following beneficial effects:

[0017] This utility model has an abutment plate and a push plate outside the winding roller. The abutment plate and the push plate can be adjusted to the left and right positions so as to position the paper tube attached to the push plate and avoid the self-adhesive label from becoming crooked during the winding process, which would result in a crooked label roll.

[0018] The pusher plate in this invention can be separated from the abutment plate, allowing workers to push the wound label roll outwards using the pusher plate, preventing the label roll from tilting when it leaves the winding roller and improving product quality. Attached Figure Description

[0029] Reference Figures 1-4According to an embodiment of the present invention, a winding mechanism for self-adhesive labels includes a frame 11, a winding roller 12 rotatably connected to the side of the frame 11, and a motor for driving the winding roller 12 to rotate inside the frame 11. The winding roller 12 is either a mechanical expansion shaft or a pneumatic expansion shaft. A protruding plate 31 can be controlled to pop out inside the winding roller 12, and the protruding plate 31 externally supports and locks the paper tube sleeved outside the winding roller 12, so that the paper tube can be driven to rotate and perform winding operations. Figure 1 As shown, in this embodiment, the take-up roller 12 is a mechanical expansion shaft, and one end of the take-up roller 12 is equipped with a handle for controlling whether the convex plate 31 pops out or not. This is a conventional setting in the prior art and will not be described in detail here.

[0030] In addition, to facilitate the positioning of the paper tube fitted outside the take-up roller 12, a paper tube positioning assembly is installed on the take-up roller 12. The paper tube positioning assembly includes a slide cylinder 13 that is slidably connected to the take-up roller 12 from left to right. An abutment plate 14 is integrally formed on one side of the slide cylinder 13. A first groove 91 is also provided in the curved surface of the take-up roller 12. A first slider 15 is slidably connected in the first groove. A threaded shaft is rotatably connected in the slide cylinder 13, and the threaded shaft is threadedly connected in the first slider 15. In addition, a knob 16 is installed at the end of the threaded shaft. In this embodiment, three sets of knobs 16, the first groove 91 and the threaded shaft are arranged at equal angles.

[0031] The operator can loosen the threaded shaft by using the knob 16 to adjust the left and right positions of the slide cylinder 13 and the abutment plate 14, and then tighten the knob 16 to fix the left and right positions of the abutment plate 14, thereby completing the position adjustment of the abutment plate 14. After the position of the abutment plate 14 is adjusted, the operator can place the paper tube sleeved on the take-up roller 12 against the abutment plate 14, and then lock it with the convex plate 31 for precise positioning.

[0032] After the paper tube fitted outside the convex plate 31 is wound up and retracted into the convex plate 31, the operator usually manually pushes the paper tube and the label roll outside it to the outside of the winding roller 12. During this process, the label roll is prone to skewing. In order to avoid the above situation and improve the quality of the label roll, in the second embodiment of the winding mechanism for self-adhesive labels, a push plate 17 is also slidably connected to the outside of the winding roller 12, and a locking component is also included for locking the relative position of the push plate 17 and the abutment plate 14.

[0033] In this second embodiment, when the paper tube is fitted over the winding roller 12 and positioned, it abuts against the push plate 17 for positioning, instead of abutting against the abutting plate 14 as in the first embodiment. In this embodiment, when the push plate 17 and the abutting plate 14 are locked together, the push plate 17 will not fit over the protrusion plate 31.

[0034] The locking assembly includes two spring grooves 21 symmetrically distributed on the left side of the push plate 17. A movable block 22 is slidably connected in the spring groove 21. A hook plate 23 is integrally formed on the left end of the movable block 22 extending to the left side of the spring groove 21. A control key 24 penetrating the curved surface of the push plate 17 is provided on the side of the movable block 22 opposite to the control key 24. A spring is installed on the side of the movable block 22 opposite to the control key 24. A through groove is provided in the abutment plate 14 to accommodate the hook plate 23 passing through.

[0035] As the push plate 17 moves to the left until it is attached to the abutment plate 14, the inclined surface inside the hook plate 23 will first abut against the edge of the through groove, so that the hook plate 23 and the movable block 22 are squeezed inward as the push plate 17 moves to the left. After the push plate 17 is completely attached to the abutment plate 14, the hook plate 23 will pop outward and hook onto the left side of the abutment plate 14, thereby locking the abutment plate 14 and the push plate 17.

[0036] When unlocking is required, the operator presses down the control key 24 and removes the hook plate 23 from the left side of the abutment plate 14. Then, the operator can push the push plate 17 to the right and push out the label paper roll and paper tube that are wrapped around the take-up roller 12. The push plate 17 can prevent the paper roll from tilting due to localized force.

[0037] Furthermore, the end of the control key 24 is equipped with an arc-shaped plate 25, which allows the operator to press down the control key 24 and unlock the push plate 17 for easy operation. In order to further increase the stability of the arc-shaped plate 25, the inner arc surface of the arc-shaped plate 25 is also provided with a movable rod that inserts into the curved surface of the push plate 17.

[0038] To prevent the push plate 17 from rotating relative to the take-up roller 12, the push plate 17 is slidably connected in the following manner: multiple second-order sliding grooves 92 are provided at equal angles on the curved surface of the take-up roller 12; the convex plate 31 is axially misaligned with the second-order sliding grooves 92; and the inner curved surface of the push plate 17 is provided with a second-order slider that is inserted into the second-order sliding groove.

[0039] To prevent jamming when the push plate 17 is pushed left and right, the push plate 17 is widened laterally to increase the width of the second slider. In order to reduce the weight of the push plate 17, an annular groove 26 is provided in the outer curved surface of the push plate 17 on the right side of the spring groove 21.

[0040] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
