Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive label processing technology, and in particular relates to a tensioning structure for a self-adhesive label die-cutting device. Background Technology

[0002] Self-adhesive labels, also known as self-adhesive labels or instant labels, are a type of identification product widely used in various fields. They are composite materials made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with a silicone-coated release liner as the backing. In practical applications, simply peeling off the backing liner allows the label to be easily affixed to various object surfaces, achieving functions such as identification, description, and decoration.

[0003] During the die-cutting process of self-adhesive labels, the label tape needs to be continuously straightened to ensure the accuracy of the die-cutting position. However, the label tape is tensioned by springs, which can easily lead to fatigue of the elastic element due to frequent expansion and contraction after prolonged use. This causes a decrease in the elastic coefficient, which in turn weakens the tension, resulting in problems such as label die-cutting position deviation and dimensional deviation. Therefore, it is necessary to provide a tensioning structure for self-adhesive label die-cutting devices that uses an adjustable push structure in conjunction with a spring tensioning element. This structure can adjust the tension according to usage requirements, address the fatigue of the elastic element, ensure that the label tape is always under tension, and ensure the accuracy of the die-cutting position.

[0022] In the following description, embodiments of the tensioning structure for the self-adhesive label die-cutting device of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a tensioning structure for a self-adhesive label die-cutting device according to an embodiment of the present invention. The structure includes fixed rollers 3 located on both sides of the inner cavity of a die-cutting machine 1. The fixed rollers 3 are rotatably connected to the die-cutting machine 1. Two rotatable die-cutting rollers 2 are installed at the center of the inner cavity of the die-cutting machine 1. A tensioning assembly 4 is disposed above the fixed rollers 3. The tensioning assembly 4 includes fixed sleeves 41 fixedly connected to the front and rear ends of the inner cavity of the die-cutting machine 1. A toothed column 42 is slidably connected to the inner cavity of the fixed sleeve 41, and the bottom end of the toothed column 42 penetrates through the fixed sleeve. A lifting seat 43 is fixedly connected to the bottom of 41. A rotating arm 44 is rotatably connected to the inner cavity of the lifting seat 43. A fixing column 6 is fixedly connected to the inner cavity of the rotating arm 44. The fixing column 6 is rotatably connected to the lifting seat 43. A torsion spring 7 is sleeved on the surface of the fixing column 6. One end of the torsion spring 7 is welded to the rotating arm 44, and the other end of the torsion spring 7 is welded to the lifting seat 43. Through the cooperation of the fixing column 6 and the torsion spring 7, the rotating arm 44 is elastically torsionally moved, so that the extrusion roller 45 can be elastically pushed, thereby making... The surface of the extrusion roller 45 can continuously extrude and tension the label tape. The extrusion roller 45 is rotatably connected between two rotating arms 44 on the same side. An adjustment assembly 5 is provided on the front side of the die-cutting machine 1. The adjustment assembly 5 includes rotating columns 51 rotatably connected to both sides of the inner cavity of the die-cutting machine 1. Gears 53 are fixedly connected to the front and rear sides of the surface of the rotating columns 51. The gears 53 mesh with the gear post 42. Worms 54 are rotatably connected to both ends of the front side of the die-cutting machine 1. The front end of the rotating column 51 passes through... A worm gear 52 is fixedly connected to the front of the die-cutting machine 1. The worm 54 meshes with the worm gear 52 at its bottom. Handwheels 55 are fixedly connected to the opposite ends of the two worms 54. By adjusting the configuration of the component 5, the cooperation between the worm 54 and the worm gear 52 drives the rotating column 51 to rotate. At the same time, under the meshing transmission of the gear 53 and the toothed column 42, the working height of the lifting seat 43 is adjusted, thereby adjusting the tension of the label tape by the extrusion roller 45.

[0024] Working Principle: In use, the user places the label tape between two die-cutting rollers 2, so that the label tape is located on the surface of the fixed roller 3. During use, the user can rotate the handwheel 55. The handwheel 55 drives the worm gear 54 to rotate during rotation. The worm gear 54 drives the worm wheel 52 that meshes with it to rotate during rotation. The worm wheel 52 drives the rotating column 51 to rotate during rotation. The rotating column 51 drives the gear 53 to rotate in the inner cavity of the fixed sleeve 41. In turn, the gear 53 drives the toothed column 42 that meshes with it to move up and down in the inner cavity of the fixed sleeve 41. During the sliding process, the toothed column 42 drives the lifting seat 43 to move downward. During the displacement process, the lifting seat 43 drives the extrusion roller 45 to contact the surface of the label tape through the rotating arm 44, thereby compressing and tensioning the label tape. At the same time as compression and tensioning, the torsion spring 7 simultaneously provides elastic compression to the extrusion roller 45, so that the surface of the label tape is subjected to elastic compression by the extrusion roller 45, thereby allowing the label tape to be continuously elastically tensioned.

[0025] In summary, this self-adhesive label die-cutting device uses a tensioning structure. Through the cooperation of the fixed roller 3 and the tensioning component 4, the label tape is supported and tensioned. At the same time, with the cooperation of the adjusting component 5, the height of the extrusion roller 45 can be adjusted, thereby adjusting the tension force. This achieves the purpose of continuous pressure tension and easy adjustment of the tension force.
