Description

Technical Field

[0001] This utility model relates to the field of webbing tensioning technology, and in particular to a simple elastic webbing tensioning device. Background Technology

[0002] Ribbons are narrow-width or tubular fabrics made from various yarns. There are many varieties of ribbons, which are widely used in various industries such as clothing, footwear, bags, industry, agriculture, military supplies, and transportation. With the development of textile technology, the raw materials used for ribbons have gradually expanded to include nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major categories of technology: weaving, braiding, and knitting. The fabric structures include plain weave, twill weave, satin weave, jacquard, double layer, multi layer, tubular, and combined weave.

[0003] After production, webbing needs to undergo quality inspection to ensure that each batch of webbing is qualified. Visual inspection and manual measurement are important parts of webbing quality inspection. In visual inspection and manual measurement, a section of webbing needs to be stretched straight and taut so that workers can clearly observe the webbing structure and measure indicators such as weft density, shrinkage ratio, loading width and thickness.

[0004] Existing webbing tensioning equipment requires rotating a screw to push a clamping plate downwards to press the ends of the webbing together before tensioning it. This process of rotating the screw to move the clamping plate up and down to loosen or tighten the ends of the webbing is time-consuming and labor-intensive, reducing the efficiency of the webbing tensioning operation.

[0005] To solve the above problems, a simple elastic webbing tensioning device is urgently needed. Utility Model Content

[0006] The purpose of this invention is to provide a simple elastic webbing tensioning device to solve the problem mentioned in the background art that the existing webbing tensioning devices are cumbersome to operate when tightening or loosening the two ends of the webbing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a simple elastic webbing tensioning device, comprising an opposing moving component and two moving plates symmetrically connected to the opposing moving component, wherein two pressing components for pressing the two ends of the webbing to the top of the two moving plates are symmetrically connected to the top of the two moving plates.

[0008] The opposing moving component is used to drive the two moving plates to move at the same speed in a direction that moves closer to or further away from each other;

[0009] The pressing assembly includes an elastic lifting mechanism connected to the top of the movable plate, and a clamping plate is connected to the elastic lifting mechanism. The pressing assembly also includes a transmission mechanism connected to the top of the movable plate and a quick drive mechanism. The quick drive mechanism can move up and down linearly to cooperate with the transmission mechanism to drive the clamping plate to rise to loosen the webbing or lower to press the webbing.

[0010] Preferably, the elastic lifting mechanism includes two insert rods symmetrically and movably inserted into the top of the movable plate. The clamping plate is movably sleeved between the outer circumferential surfaces of the two insert rods. Limiting plates are fixedly connected to the top ends of the two insert rods. Two first elastic elements are symmetrically and fixedly connected between the bottom of the clamping plate and the top of the movable plate. The advantage of this arrangement is that, through the cooperation of the two insert rods and the two first elastic elements, the clamping plate can move stably up and down, ensuring that the loosening and clamping operations of the webbing end are carried out smoothly.

[0011] Preferably, the transmission mechanism includes two vertical plates symmetrically fixedly connected to the top of the movable plate. The tops of the two vertical plates are symmetrically connected to two pairs of cam-shaped pressure plates via two first rotating rods. The two pairs of pressure plates are arranged in an inverted V-shape, and their bottom ends can press tightly against the top surface of the clamping plate. The transmission mechanism also includes two pairs of levers symmetrically fixedly connected to the left and right ends of the two first rotating rods. The two pairs of levers are arranged in a V-shape. The advantage of this arrangement is that by simply pressing the bottom ends of the two pairs of pressure plates downwards until they press against the clamping plate, the clamping plate can easily clamp the webbing end in conjunction with the movable plate. When it is necessary to release the clamping of the webbing end, simply move the top of the lever upwards to move the bottom end of the pressure plate upwards. Simultaneously, the first elastic element pushes the clamping plate upwards to release the webbing end. This makes the clamping and releasing operation of the webbing end simple and convenient, effectively improving the convenience and practicality of the tensioning device.

[0012] Preferably, the rapid drive mechanism includes a crossbar, which is a square bar. Two push plates are symmetrically fixedly sleeved on the outer circumference of the crossbar. The two push plates can respectively abut against the top surfaces of the four pairs of pressure plates on the left and right. The advantage of this arrangement is that after rotating the push plate to a vertical position so that the push plate passes through the gap between the tops of the two pairs of levers, the crossbar is rotated 90 degrees forward or backward to make the push plate vertical. Then, the crossbar is pressed down until the push plate pushes the bottom end of the pressure plate downward to move the clamping plate downward to clamp the end of the webbing. When it is necessary to release the clamping operation of the end of the webbing, it is only necessary to pull the crossbar upward, so that the push plate moves upward until the top of the lever is pushed upward. In this way, the lever can drive the bottom end of the pressure plate upward through the first rotating rod, so that the clamping plate moves upward and releases the end of the webbing. This makes the clamping and releasing operation of the end of the webbing simple and convenient.

[0013] Preferably, two auxiliary pressing components are symmetrically connected to the top of the two movable plates. Each auxiliary pressing component includes a rotating column rotatably connected to the top of the movable plate. A limiting groove is formed at the top of the rotating column, and the left and right ends of the limiting groove pass through the outer side wall of the rotating column. The crossbar can be inserted into the limiting groove. The width of the limiting groove and the width of the crossbar are in clearance fit. The advantage of this setting is that only the crossbar needs to be inserted into the two limiting grooves, so that the crossbar and the push plate are in the center position and the crossbar is prevented from rotating. This ensures that the push plate can push the bottom ends of the four pairs of pressure plates downward evenly and stably and push the clamping plate to clamp the end of the webbing, ensuring the reliability and stability of the clamping operation.

[0014] Preferably, the auxiliary pressing assembly further includes a screw threaded into the top of the movable plate, a circular plate fixedly connected to the top of the screw, and the bottom end of the rotating column rotatably connected to the top surface of the circular plate. The inner bottom wall of the limiting groove is flush with the top surface of the circular plate. The auxiliary pressing assembly includes a scale fixedly connected to the top of the movable plate. The value corresponding to the scale line aligned with the top surface of the circular plate is the required reading. The scale value on the scale is the distance between the bottom surface of the clamping plate and the top surface of the movable plate when the bottom end of the crossbar abuts against the inner bottom wall of the limiting groove. The advantage of this gap setting is that when clamping the ends of webbing of different thicknesses and materials, the height of the circular plate can be adjusted by rotating the circular plate and screw. At the same time, the scale value aligned with the top surface of the circular plate can be observed until the scale value aligned with the top surface of the circular plate is the value required for tensioning the webbing. This ensures that the ends of the webbing are firmly clamped while avoiding excessive pressure that could cause severe deformation of the webbing ends. This ensures that subsequent quality inspection of the webbing can proceed smoothly, ensuring the accuracy and reliability of the inspection.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, the clamping component allows the operator to simply move the fast drive mechanism up and down in a straight line to coordinate with the transmission mechanism to raise the clamping plate to loosen the webbing or lower it to clamp the webbing, thereby conveniently and quickly completing the clamping operation on the end of the webbing, effectively improving the convenience and practicality of the device.

[0017] 2. In this utility model, the auxiliary pressing component allows for the adjustment of the height of the circular plate by rotating the circular plate and screw when clamping the ends of webbing of different thicknesses and materials. Simultaneously, the scale value aligned with the top surface of the circular plate is observed until the value aligned with the top surface of the circular plate is the required value for tensioning the webbing. This ensures that the ends of the webbing are securely clamped while avoiding excessive pressure that could cause severe deformation of the webbing ends. This ensures that subsequent quality inspection of the webbing can proceed smoothly, guaranteeing the accuracy and reliability of the inspection. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 The simple elastic webbing tensioning device shown includes a moving component 1 and two moving plates 2 symmetrically connected to the moving component 1. Two pressing components 3 for pressing the two ends of the webbing to the top of the two moving plates 2 are symmetrically connected to the top of the moving components 1.

[0027] The opposing moving component 1 is used to drive the two moving plates 2 to move at the same speed in a direction that moves closer to or further away from each other;

[0028] The pressing assembly 3 includes an elastic lifting mechanism 31 connected to the top of the movable plate 2, and a clamping plate 32 connected to the elastic lifting mechanism 31. The pressing assembly 3 also includes a transmission mechanism 33 connected to the top of the movable plate 2, and a fast drive mechanism 34. The fast drive mechanism 34 can move up and down linearly to cooperate with the transmission mechanism 33 to drive the clamping plate 32 to rise to loosen the webbing or lower to press the webbing.

[0029] The opposing moving component 1 includes two symmetrically distributed support plates 11. Two guide rods 12 are symmetrically fixedly connected between the adjacent sides of the two support plates 11. A threaded rod 13 is rotatably connected between the adjacent sides of the two support plates 11. Two moving plates 2 are symmetrically movably sleeved between the outer circumferential surfaces of the two guide rods 12. The two moving plates 2 are symmetrically threaded onto the outer thread surface of the threaded rod 13. The right end of the threaded rod 13 passes through the right support plate 11 and is fixedly connected to a disc 14. A handle 15 is rotatably connected to the right side of the disc 14. The axis of the handle 15 does not coincide with the axis of the disc 14, but the axis of the threaded rod 13 coincides with the axis of the disc 14. This allows the operator to simply rotate the disc 14 clockwise or counterclockwise by rotating the handle 15. The disc 14 then rotates the threaded rod 13 clockwise or counterclockwise. The threaded rod 13, in conjunction with the two guide rods 12, can move the two moving plates 2 in opposite directions, thereby achieving the tensioning operation of the webbing.

[0030] refer to Figures 3-5 The elastic lifting mechanism 31 includes two insert rods 311 that are symmetrically inserted into the top of the movable plate 2. The clamping plate 32 is movably sleeved between the outer peripheral surfaces of the two insert rods 311. Limiting plates are fixedly connected to the top of the two insert rods 311. Two first elastic elements 312 are symmetrically fixedly connected between the bottom of the clamping plate 32 and the top of the movable plate 2.

[0031] Specifically, the two insert rods 311, in conjunction with the two first elastic elements 312, enable the clamping plate 32 to move stably up and down, ensuring the smooth operation of loosening and clamping the webbing ends.

[0032] refer to Figures 2-5 The transmission mechanism 33 includes two vertical plates 331 that are symmetrically fixedly connected to the top of the movable plate 2. The top of the two vertical plates 331 is symmetrically connected to two pairs of cam-shaped pressure plates 332 by two first rotating rods. The two pairs of pressure plates 332 are distributed in an inverted V-shape. The bottom ends of the two pairs of pressure plates 332 can press tightly against the top surface of the clamping plate 32. The transmission mechanism 33 also includes two pairs of levers 333 that are symmetrically fixedly connected to the left and right ends of the two first rotating rods. The two pairs of levers 333 are distributed in a V-shape.

[0033] Specifically, simply press the bottom ends of the two pairs of pressure plates 332 downwards until they press the clamping plate 32 tightly. This allows the clamping plate 32 to work with the moving plate 2 to clamp the end of the webbing. When it is necessary to release the clamping of the webbing end, simply move the top of the lever 333 upwards to move the bottom end of the pressure plate 332 upwards. At the same time, the first elastic element 312 pushes the clamping plate 32 upwards to release the webbing end. This makes the clamping and releasing operation of the webbing end simple and convenient, effectively improving the convenience and practicality of the tensioning device.

[0034] refer to Figures 1-5 The fast drive mechanism 34 includes a crossbar 341, which is a square bar. Two push plates 342 are symmetrically fixedly sleeved on the outer circumference of the crossbar 341. The two push plates 342 can respectively press against the top surface of the four pairs of pressure plates 332 on the left and right.

[0035] Specifically, simply rotate the push plate 342 to a vertical position so that it passes through the gap between the tops of the two pairs of levers 333. Then, rotate the crossbar 341 forward or backward by 90 degrees to make the push plate 342 vertical. Next, press the crossbar 341 down until the push plate 342 pushes the bottom of the pressure plate 332 downward to rotate it, thereby pushing the clamping plate 32 downward to clamp the end of the webbing. When it is necessary to release the clamping operation of the webbing end, simply pull the crossbar 341 upward, so that the push plate 342 moves upward until the top of the lever 333 is pushed upward. In this way, the lever 333 can drive the bottom of the pressure plate 332 to rotate upward through the first rotating rod, thereby moving the clamping plate 32 upward and releasing the end of the webbing. This makes the clamping and releasing operation of the webbing end simple and convenient.

[0036] refer to Figures 1-4 Two auxiliary pressing components 4 are symmetrically connected to the top of the two movable plates 2. The auxiliary pressing components 4 include a rotating column 41 rotatably connected to the top of the movable plate 2. A limiting groove 42 is opened at the top of the rotating column 41. The left and right ends of the limiting groove 42 pass through the outer side wall of the rotating column 41 respectively. A crossbar 341 can be inserted into the limiting groove 42. The width of the limiting groove 42 and the width of the crossbar 341 are in clearance fit.

[0037] Specifically, simply insert the crossbar 341 into the two limiting slots 42, so that the crossbar 341 and the push plate 342 are in the center position, and prevent the crossbar 341 from rotating. This ensures that the push plate 342 can evenly and stably push the bottom of the four pairs of pressure plates 332 to rotate downward and push the clamping plate 32 to clamp the end of the webbing, ensuring the reliability and stability of the clamping operation.

[0038] refer to Figures 2-5The auxiliary pressing component 4 also includes a screw 43 threaded into the top of the movable plate 2. A circular plate 44 is fixedly connected to the top of the screw 43. The bottom end of the rotating column 41 is rotatably connected to the top surface of the circular plate 44. The inner bottom wall of the limiting groove 42 is flush with the top surface of the circular plate 44. The auxiliary pressing component 4 includes a scale 45 fixedly connected to the top of the movable plate 2. The value corresponding to the scale line of the scale 45 aligned with the top surface of the circular plate 44 is the required reading number. The scale value on the scale 45 is the gap value between the bottom surface of the clamping plate 32 and the top surface of the movable plate 2 when the bottom end of the crossbar 341 abuts against the inner bottom wall of the limiting groove 42.

[0039] Specifically, when clamping the ends of webbing of different thicknesses and materials, the height of the circular plate 44 can be adjusted by rotating the circular plate 44 and the screw 43. At the same time, the scale value on the scale 45 aligned with the top surface of the circular plate 44 can be observed until the scale value aligned with the top surface of the circular plate 44 is the value required to tension the webbing. This ensures that the ends of the webbing are firmly clamped while avoiding excessive pressure that could cause severe deformation of the webbing ends. This ensures that subsequent quality inspection of the webbing can proceed smoothly, ensuring the accuracy and reliability of the inspection.

[0040] Working principle: Place the two ends of the webbing to be tensioned on top of the two moving plates 2 respectively, so that the two ends of the webbing are directly below the two clamping plates 32 respectively.

[0041] Next, depending on the thickness and material of the webbing to be tensioned, rotate the circular plate 44 and screw 43 to adjust the height of the circular plate 44. At the same time, observe the scale value on the scale 45 aligned with the top surface of the circular plate 44 until the scale value aligned with the top surface of the circular plate 44 is the value required to tension the webbing. This ensures that the end of the webbing is firmly clamped while avoiding excessive pressure that could cause severe deformation of the webbing end. This ensures that the subsequent quality inspection of the webbing can proceed smoothly, ensuring the accuracy and reliability of the inspection.

[0042] Then, after rotating the push plate 342 to the vertical position, the push plate 342 passes through the gap between the tops of the two pairs of levers 333. Then, rotate the crossbar 341 forward or backward by 90 degrees to make the push plate 342 horizontal and insert the crossbar 341 into the two limiting grooves 42 to prevent the crossbar 341 from rotating. Then, press the crossbar 341 down until the push plate 342 pushes the bottom of the pressure plate 332 to rotate downward to push the clamping plate 32 to move downward and clamp the end of the webbing.

[0043] Then, the handle 15 drives the disc 14 to rotate clockwise, and the disc 14 drives the threaded rod 13 to rotate clockwise. The threaded rod 13, together with the two guide rods 12, can drive the two moving plates 2 to move in opposite directions, thereby realizing the tensioning operation of the webbing.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
