Abstract
Description
Technical Field
[0001] This utility model relates to an improvement of a strip fabric production device, specifically an adjustable strip fabric tensioning device. Background Technology
[0002] Label tape is a strip of fabric used to identify product information on clothing and other products. It is produced by coating a base fabric with a material to make it stiff and smooth, followed by slitting. After slitting, the label tape and other strips of fabric are connected to different take-up rollers via winding conveyors at different heights and directions. The strips are narrow but long, requiring a certain tension during winding to ensure the fabric roll reaches a certain density and prevent it from unwinding. Therefore, tensioning devices are needed along the conveying path. Existing tensioning devices are mostly fixed in direction, and the required tension varies depending on the height and position of the conveying structure. While existing devices have a certain adjustment range, they are insufficient for larger-scale production and therefore require improvement. Utility Model Content
[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the prior art and to provide an adjustable strip fabric tensioning device.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The adjustable tensioning device includes an adjustable positioning buckle, an adjustable direction frame, a swing frame, a tensioning wheel, and a counterweight fixing frame. The adjustable positioning buckle is fixed to the positioning rod in a ring shape. The adjustable positioning buckle is fixed at any angle on the outer diameter of the positioning rod. The lower part of the adjustable positioning buckle is connected to the adjustable direction frame. The adjustable direction frame is horizontally adjustable and fixed between the adjustable positioning buckles. The swing frame is connected to the adjustable direction frame. The middle part of the swing frame is rotatably connected to the adjustable direction frame. A tensioning wheel is provided at one end of the swing frame. A guide wheel is provided in the middle of the swing frame. The strip of fabric passes through the guide wheel and the tensioning wheel in sequence and is tensioned by the tensioning wheel. A counterweight fixing frame is provided at the other end of the swing frame. The counterweight fixing frame is provided with mounting holes and a counterweight is fixed through the mounting holes. The adjustable functions of this design are mainly reflected in the adjustable conveying direction and angle, as well as the adjustable tension counterweight. The adjustable positioning buckle can adjust the angle with the positioning rod as the axis, realizing different pitch angle settings. The adjustable direction frame can adjust the conveying direction and adjust different swing angles. Therefore, multiple conveying orientation settings can be realized, effectively improving the space utilization of the conveyor line and realizing high-efficiency production. At the same time, the tension force is adjusted by an adjustable counterweight. Different quantities and qualities of counterweights can be installed as needed, with a high degree of freedom in adjustment.
[0005] Furthermore, the adjustable directional frame includes a connecting screw, a locking nut assembly, and a tensioning frame. One end of the connecting screw is fixed to the lower part of the adjustable positioning ring, and the other end is screwed onto the tensioning frame. The locking nut assembly is also screwed onto the connecting screw, pressing it against the tensioning frame. A rotation space is formed under the tensioning frame, and the swing frame is disposed in the rotation space. The connecting screw itself has a good steering angle function, and is effectively locked by the locking nut assembly. In this vibration-free working environment, the structure can maintain stability for a long time.
[0006] Furthermore, the adjustable positioning buckle includes a semi-circular mating structure with an opening and closing mechanism. The two semi-circles are rotatably connected by a hinge, and the opposite side is fixed by bolts. Anti-slip textures are formed on the inner surface of the adjustable positioning buckle, and these textures press firmly against the surface of the positioning rod. The semi-circular mating structure offers high installation efficiency and facilitates maintenance. The anti-slip textures provide a secure grip, preventing misalignment.
[0007] Furthermore, the swing frame is a rigid, straight structure with a counterweight fixing frame welded to one end. The counterweight fixing frame has a fixing surface larger than the width of the swing frame, and multiple mounting holes are evenly distributed on the counterweight fixing frame. The distance between the mounting holes is greater than the outer diameter of the counterweight. The swing frame itself has good rigidity and is not easily deformed. The counterweight fixing frame forms a certain protective distance, allowing the counterweight to be placed within it, thus avoiding interference with the working structure.
[0008] Furthermore, both the tension wheel and the guide wheel have bearing rings on their shafts, allowing them to rotate freely under the guidance of the bearing rings. The edges of both the tension wheel and the guide wheel are formed with protruding retaining rings, and the circular surfaces between the retaining rings allow the strip of fabric to pass through. The bearing rings have a low-resistance structure, enabling smooth rotation with low resistance. The retaining rings on the sides of the tension wheel and the guide wheel prevent fabric skewing and avoid jamming into the rotating structure.
[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement on the tensioning structure of strip fabric mainly used for trademark tape production. It has flexible directional adjustment and tension adjustment functions, is suitable for use in large-scale production equipment, improves production efficiency, improves equipment maintenance efficiency, and reduces operating costs.
