Description

Technical Field

[0001] The utility model relates to the technical field of label production, in particular to a label fixing structure with adjustable spacing. Background Technique

[0002] We use various daily necessities in our daily life. In order to show the performance of the products to users and the problems that need attention during use, etc., labels are set on the items. When the label tape is produced, it is necessary to limit the movement of the label tape on the roller. Mainly, blocking parts are arranged on both sides to limit its deviation during movement. Therefore, a label fixing structure will be used.

[0003] The existing label fixing structure is to directly fix two limiting rings on the roller by welding or bonding at a fixed spacing to achieve the limitation of the movement of the label tape. However, this design results in the need to use a variety of combinations of limiting rings and rollers with different widths for label tapes of different widths. During use, manufacturing enterprises need to stockpile fixing structures with various size combinations, which is not convenient during use, requires frequent disassembly and replacement, and also increases costs. Therefore, we propose a label fixing structure with adjustable spacing to solve the problems encountered above. Content of the Utility Model

[0018] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 - Figure 3As shown in the figure, an adjustable-spacing label fixing structure includes a fixed roller 1, and sleeve tubes 2 are fixedly connected to the left and right sides of the outer side of the fixed roller 1 respectively; an adjusting assembly, which includes an intermediate structure 3 fixedly connected inside the sleeve tube 2. The front and rear sides of the connection part of the two intermediate structures 3 are respectively rotatably connected with short shafts 4, and gears 5 are fixedly connected to the outside of the short shafts 4. Bar-shaped slots 13 are respectively formed in the front and rear sides of one side of the intermediate structure 3, and a rack 6 is arranged in each bar-shaped slot 13. The racks 6 in the bar-shaped slots 13 on the same intermediate structure 3 are at the same height. The rack 6 is slidably connected to the inner wall of the adjacent side of the adjacent bar-shaped slot 13, and the same-side ends of the two racks 6 are fixedly connected with the same arc-shaped frame 7. The other end of the arc-shaped frame 7 is fixedly connected with a limiting ring 8. The limiting ring 8 is slidably connected to the outside of the sleeve tube 2. The rack 6 meshes with the adjacent gear 5. A threaded hole is formed in the limiting ring 8, and a damping bolt 9 is threadedly connected in the threaded hole.

[0020] It should be noted that the intermediate structure 3 is used to fix and hide the gear 5 and the rack 6. When the gear 5 meshes with the upper and lower groups of racks 6 at the same time, when one side of the rack 6 moves, the other side of the rack 6 can move synchronously, simplifying the operation steps. The bar-shaped slot 13 allows the rack 6 to slide therein. Oval slots are symmetrically arranged at the four corners of the intermediate structure 3 to reduce the material consumption and lower the manufacturing cost. The damping bolt 9 is manually rotated when needed, and one end of it presses the surface of the sleeve tube 2 through the cooperation with the threaded hole to increase the sliding damping of the limiting ring 8 on the sleeve tube 2, so as to fix the current position of the limiting ring 8. Through the provided adjusting assembly, the distance between the two limiting rings 8 can be adjusted according to the actual width of the label tape. The adjustment operation is simple and only needs to be pulled to move. Moreover, no slots are provided on the surface of the fixed roller 1, which does not affect the normal movement of the label tape. When it is necessary to lock the position of the limiting ring 8, the operation and structure are also simple enough, convenient to use, avoiding the need to stockpile a variety of fixing structures, and reducing the production cost of the label tape.

[0021] One end of the sleeve tube 2 is fixedly connected with a connecting part 10, and a ring tube 11 is fixedly connected to one side of the connecting part 10. The ring tube 11 is sleeved on the outside of the fixed roller 1. The ring tube 11 is used to increase the contact area between the sleeve tube 2 and the fixed roller 1 and improve the supporting effect of the fixed roller 1 on the sleeve tube 2.

[0022] A positioning hole 12 is formed on the adjacent surface of one of the sleeve tubes 2, and a protrusion is fixedly connected to the adjacent surface of the other sleeve tube 2. The protrusion and the positioning hole 12 are symmetrically distributed at the four corners. The protrusion and the positioning hole 12 are used for pre-positioning when the two sleeve tubes 2 are connected, so as to ensure the connection accuracy.

[0023] A through slot is formed on the adjacent side of the sleeve tube 2, and the cross-sectional area of the through slot is larger than the cross-sectional area of the bar-shaped slot 13. The through slot is used to allow the rack 6 and the gear 5 to pass through to avoid interference.

[0024] One end of the damping bolt 9 close to the sleeve 2 is fixedly connected with a rubber pad, which can reduce the damage caused by the friction between the bottom end of the damping bolt 9 and the surface of the sleeve 2. At the same time, it can increase the friction damping during contact and improve the fixing effect.

[0025] When the present utility model is specifically implemented: when it is necessary to adjust the distance between the two limiting rings 8 according to the width of the label tape, first rotate the damping bolts 9 on the two limiting rings 8, so that they are screwed out through the thread fit with the threaded holes, and one end of them no longer contacts the surface of the sleeve 2. Then gently pull one side of the arc-shaped frame 7 to drive the rack 6 and the limiting ring 8 to move. At the same time, drive the gear 5 to rotate through the meshing of the rack 6 and the gear 5, and then drive the other rack 6 and the arc-shaped frame 7 and the limiting ring 8 to move in the opposite direction to a suitable distance through the meshing of the gear 5 and the other rack 6. Then reselect the two damping bolts 9, so that one end of them contacts and presses the surface of the sleeve 2 again to lock the current position of the limiting ring 8.

[0026] The preferred embodiments of the present utility model disclosed above are only used to help explain the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific implementation manners. Obviously, many modifications and changes can be made according to the content of this specification. These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the present utility model, so that those skilled in the art can understand and utilize the present utility model well. The present utility model is only limited by the claims and their full scope and equivalents.
