Abstract
Description
Technical Field
[0001] This utility model relates to the field of labeling equipment technology, specifically to a tensioning mechanism for a labeling component. Background Technology
[0002] When labeling products, traction rollers are usually installed to ensure that the label raw materials maintain appropriate tension during operation. This applies pressure to the label, ensuring that it remains taut during operation.
[0003] To facilitate better adjustment of the tension of the label material, existing traction rollers typically consist of two sets of rollers. By passing the label material between the two sets of rollers, pressure is applied to the label material by adjusting the position of one set of rollers, and then the rotation of the other set of rollers is controlled by a motor, thereby driving the label to be conveyed. This allows for the adjustment of the tension of the label material.
[0004] However, when the label material is placed on the traction roller, it is usually directly and tightly attached to the traction roller. But in actual operation, due to the different label specifications used, smaller labels are prone to shifting on the traction roller under the action of extrusion pressure. This may cause the local tension of the label material on the upper roller to increase, making it easy for the label to wrinkle when it is pasted on the product, resulting in failure to paste, or even causing the label material to break. Utility Model Content
[0005] The purpose of this invention is to provide a tensioning mechanism for a labeling component to solve the problem mentioned in the background art where label raw materials are prone to shifting on the traction roller.

[0012] Preferably, a rotating component is provided on one side of the positioning block.
[0013] Preferably, the positioning groove communicates with the through groove, and the connecting plate is provided with multiple sets of positioning grooves, which match the positioning blocks.
[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0026] like Figure 1 - Figure 6 As shown, this application provides a tensioning mechanism for a labeling assembly, including: a labeling machine body 1, a mounting frame 2 on the labeling machine body 1, a first traction roller 4 on the mounting frame 2, a second traction roller 5 on the mounting frame 2, and a label raw material 3 on the first traction roller 4. It also includes: a correction assembly on the mounting frame 2, the correction assembly including a torsion spring 8 and a limiting groove 6, the limiting groove 6 being disposed on the second traction roller 5, the torsion spring 8 being disposed on the mounting frame 2, a connecting plate 14 being disposed on the torsion spring 8, a cover plate 12 being disposed on the connecting plate 14, and a limit rod 15 being disposed on the cover plate 12. The correction assembly is used for correcting the deviation of the label raw material 3.
[0027] Specifically, such as Figure 5As shown, the correction assembly also includes a storage groove 13 disposed on the mounting frame 2. A rotating shaft 7 is rotatably disposed inside the storage groove 13. A connecting plate 14 is disposed outside the rotating shaft 7. A torsion spring 8 is disposed between the connecting plate 14 and the storage groove 13. The torsion spring 8 is disposed outside the rotating shaft 7. Through the elastic force of the torsion spring 8, the cover plate 12 can be driven to tightly adhere the label raw material 3 to the second traction roller 5.
[0028] Specifically, such as Figure 6 As shown, a T-shaped block 19 is provided on one side of the limiting rod 15, and a T-shaped groove 16 is provided on the connecting plate 14 corresponding to the T-shaped block 19. Two sets of T-shaped blocks 19 are movably arranged in the T-shaped groove 16. Through the cooperation of the T-shaped block 19 and the T-shaped groove 16, the movement direction of the limiting rod 15 can be limited.
[0029] Specifically, such as Figure 4 As shown, the limiting groove 6 matches the limiting rod 15. Through the cooperation of the limiting groove 6 and the limiting rod 15, the label raw material 3 can be effectively prevented from running off-center on the second traction roller 5.
[0030] Specifically, such as Figure 4 As shown, a fixing plate 9 is provided on one side of the mounting bracket 2, and a threaded rod 10 is threaded on the fixing plate 9. A blocking ball 11 is provided on the side of the threaded rod 10 away from the mounting bracket 2. Through the cooperation of the blocking ball 11 and the threaded rod 10, damage to the label raw material 3 can be avoided when the cover plate 12 covers the label raw material 3 of different thicknesses.
[0031] A fixing component is provided on the connecting plate 14. The fixing component includes a positioning groove 18 and a lead screw 20. The positioning groove 18 is provided on the connecting plate 14, and the lead screw 20 is provided on the limiting rod 15. A positioning block 21 is provided on the lead screw 20. The fixing component is used to fix the limiting rod 15.
[0032] Specifically, such as Figure 6 As shown, the fixing assembly also includes a lead screw 20 threaded onto the T-shaped block 19, and a through groove 17 corresponding to the lead screw 20 on the connecting plate 14. The through groove 17 passes through the connecting plate 14 and communicates with the T-shaped groove 16. The through groove 17 facilitates the movement of the lead screw 20 when the T-shaped block 19 moves within the T-shaped groove 16.
[0033] Specifically, such as Figure 6 As shown, a rotating component 22 is provided on one side of the positioning block 21. The rotating component 22 makes it easier for the operator to control the rotation of the lead screw 20.
[0034] Specifically, such as Figure 6As shown, the positioning groove 18 is connected to the through groove 17. Multiple sets of positioning grooves 18 are provided on the connecting plate 14. The positioning groove 18 matches the positioning block 21. Through the cooperation of the positioning block 21 and the positioning groove 18, the position of the limiting rod 15 can be fixed.
[0035] In this embodiment: by controlling the T-block 19 to slide within the T-groove 16, the two sets of limiting rods 15 are engaged in the corresponding limiting grooves 6, thereby restricting the label material 3 and effectively preventing the label material 3 from deviating on the second traction roller 5. The elastic force of the torsion spring 8 can drive the cover plate 12 to press the label material 3 tightly against the second traction roller 5. After adjusting the position of the limiting rod 15, by turning the rotating part 22, the rotation of the screw 20 can drive the positioning block 21 to engage in the positioning groove 18, thereby quickly fixing the position of the limiting rod 15 and keeping the limiting rod 15 stable during use.
[0036] The specific solution is as follows: When it is necessary to correct the deviation of label raw materials 3 of different specifications, the operator controls the movement of two sets of T-blocks 19 within the T-groove 16, thereby aligning the limiting rod 15 with the corresponding limiting groove 6. Then, by turning the rotating part 22, the operator can rotate the lead screw 20, which in turn causes the positioning block 21 to engage with the corresponding positioning groove 18, thus fixing the position of the limiting rod 15. Then, through the elastic force of the torsion spring 8, the limiting rod 15 can be engaged with the limiting groove 6, thus keeping the label raw material 3 between the two sets of limiting rods 15, effectively preventing the label raw material 3 from deviating. Since the thickness of label raw materials 3 of different specifications is inconsistent, in order to prevent the elastic force of the torsion spring 8 from causing the cover plate 12 to squeeze the label raw material 3 and damage it, the operator adjusts the position of the blocking ball 11 by turning the threaded rod 10 according to the thickness of the label raw material 3, thereby protecting the label raw materials 3 of different thicknesses.
[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in detail for the sake of brevity.
