Description

Technical Field

[0001] This utility model relates to the field of fabric stretching and processing technology, specifically to a fabric stretching and shaping device. Background Technology

[0002] Fabric tenter frame setting is a finishing process for fabrics. It involves unfolding the fabric using equipment such as tenter frames, and then using high temperature and appropriate tension to bring the fabric to the specified dimensions in the width and length directions. This process improves the fabric's smoothness, feel, and stability, enhances its appearance and performance, and ensures that the fabric width is uniform and the shrinkage rate is controlled within a certain range to meet the requirements of subsequent processing and different applications.

[0003] During the tenter frame process, the fabric needs to be heated. Furthermore, different fabrics require different heating processes, resulting in varying heating times. Traditional tenter frame processing equipment uses two heating plates, through which the fabric is passed. However, the heating range of the plates is not adjustable. Especially for fabrics requiring longer heating times, the only solution is to reduce the fabric conveying speed to maintain the required heating duration, which significantly reduces processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fabric stretching and shaping device, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] The fabric stretching and setting device includes a worktable. On one side of the worktable, there is a heating space for the fabric to pass through and be heated. Reversing rollers are arranged at intervals from top to bottom on both sides of the heating space. The reversing rollers on both sides are staggered. On the downstream side of the heating space on the worktable, there is a pair of stretching rollers arranged vertically. The two stretching rollers can rotate in opposite directions. The fabric passes through the two stretching rollers and is used for both traction conveying and radial stretching.

[0007] Therefore, by setting several reversing rollers in the heating space, the fabric can extend its travel within the reversing rollers as it passes through the heating space, thereby increasing the heating time of the fabric without slowing down the fabric conveying process. This does not affect the efficiency of fabric stretching and shaping. By passing the fabric around the corresponding number of reversing rollers, the travel of the fabric in the heating space can be adjusted, thereby adjusting the heating time of the fabric to adapt to the heating requirements of different types of fabrics, resulting in high versatility.

[0008] Furthermore, a pair of first supports are fixed on the workbench, and two electric heating plates arranged vertically are set between the two first supports, forming a heating space between the two electric heating plates. The two ends of each reversing roller are rotatably connected to the first support on the corresponding side.

[0009] Furthermore, a pair of second supports are symmetrically fixed on the workbench downstream of the first support. A conveying roller is rotatably installed between the two second supports. Traction wheels are provided above both ends of the conveying roller. The two traction wheels are arranged to rotate in opposite directions to stretch the fabric in the weft direction.

[0010] Furthermore, a pair of third supports are fixed on the workbench downstream of the second support. Two stretching rollers are rotatably installed between the two third supports. A drive motor B is fixed on one of the third supports. The output shaft of the drive motor B is fixed to one side of the shaft end of one of the stretching rollers. Gears are fixed on the other side of the shaft ends of the two stretching rollers respectively, and the two gears mesh with each other.

[0011] Furthermore, each of the two second brackets has a mounting plate on one side that is close to the other, and a drive motor A is fixed on each of the two mounting plates. A shaft is fixed on the output shaft of each of the two drive motors A, and the two traction wheels are respectively fixed on the ends of the shafts on the corresponding sides.

[0012] Furthermore, each of the two second brackets has a suspension plate fixed on one side that is close to the other. An adjusting screw is installed in the threaded hole of the suspension plate, and the bottom end of the two adjusting screws is rotatably connected to the top of the mounting plate on the corresponding side.

[0013] Furthermore, guide rods are vertically slidably inserted into the guide holes on both suspension plates, and the bottom ends of the two guide rods are fixedly connected to the top of the mounting plates on the corresponding sides.

[0014] Furthermore, a torsion handle is provided at the top of the adjusting screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention, by setting several reversing rollers within the heating space, extends the fabric's travel within the rollers as it passes through the heating space. This increases the fabric's heating time without requiring deceleration during transport, without affecting the fabric's stretching and shaping efficiency. By passing the fabric around a corresponding number of reversing rollers, the travel of the fabric within the heating space can be adjusted, thereby adjusting the fabric's heating time to suit the heating needs of different types of fabrics, demonstrating high versatility.

[0017] This invention involves heating the fabric and then passing it over the conveyor rollers. Two traction wheels press down on both sides of the fabric and rotate in opposite directions to pull the two sides of the fabric away from each other, thus stretching the fabric in the weft direction. The fabric is then passed between two stretching rollers, which rotate in opposite directions to pull and convey the fabric. In addition, the two stretching rollers squeeze the fabric to achieve warp stretching, ensuring that the fabric is fully stretched in both the warp and weft directions, effectively improving the shaping effect.

Detailed Implementation

[0023] Please see Figures 1-4 The fabric stretching and shaping device provided by this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] This fabric stretching and setting device includes a workbench 1. On one side of the workbench 1, there is a heating space 01 through which the fabric passes for heating. Reversing rollers 3 are arranged at intervals from top to bottom on both sides of the heating space 01. The reversing rollers 3 on both sides are staggered. On the workbench 1, on the downstream side of the heating space 01, there is a pair of stretching rollers 6 arranged vertically. The two stretching rollers 6 can rotate in opposite directions. The fabric passes between the two stretching rollers 6, which is used for both traction conveying and radial stretching.

[0027] This invention provides several reversing rollers 3 within the heating space 01. When the fabric passes through the heating space 01, the fabric passes around each reversing roller 3 in sequence, which extends the travel time of the fabric within the reversing rollers 3. This increases the heating time of the fabric without slowing down the fabric conveying process, and does not affect the efficiency of fabric stretching and shaping.

[0028] In addition, by passing the fabric around a corresponding number of reversing rollers 3, the travel of the fabric within the heating space 01 can be adjusted, thereby adjusting the heating time of the fabric to suit the heating requirements of different types of fabric.

[0029] Specifically, a pair of first supports 11 are fixed on the workbench 1, and two electric heating plates 2 arranged vertically are set between the two first supports 11. A heating space 01 is formed between the two electric heating plates 2. The fabric passes through the space between the two electric heating plates 2. The fabric can be heated from the top and bottom sides by the two electric heating plates 2 to ensure high heating uniformity.

[0030] In addition, each reversing roller 3 is rotatably connected to the first bracket 11 on the corresponding side at both ends, so that the reversing roller 3 can rotate when the fabric is conveyed, thereby reducing the frictional resistance during conveying.

[0031] Specifically, a pair of second supports 12 are symmetrically fixed on the workbench 1 downstream of the first support 11. A conveying roller 4 is rotatably installed between the two second supports 12. Traction wheels 5 are respectively provided above both ends of the conveying roller 4. The two traction wheels 5 are arranged to rotate in opposite directions to stretch the fabric in the weft direction.

[0032] After the fabric is heated and drawn out in the heating space 01, it is supported on the conveyor roller 4. Two traction wheels 5 press on the two sides of the fabric and rotate in opposite directions. The two traction wheels 5 can pull the two sides of the fabric away from each other and stretch them, thereby realizing the weft stretching and extension of the fabric.

[0033] Specifically, a pair of third supports 13 are fixed on the workbench 1 downstream of the second support 12. Two tension rollers 6 are rotatably installed between the two third supports 13. A drive motor B61 is fixed on one of the third supports 13. The output shaft of the drive motor B61 is fixed to one side of the shaft end of one of the tension rollers 6. Gears 62 are fixed on the other side of the shaft ends of the two tension rollers 6 respectively. The two gears 62 mesh with each other.

[0034] The drive motor B61 drives one of the tenter rollers 6 to rotate. Under the meshing transmission of the two gears 62, the other tenter roller 6 is driven to rotate, and the fabric passes between the two tenter rollers 6. The two tenter rollers 6 rotate in opposite directions, which can traction and convey the fabric. In addition, the two tenter rollers 6 squeeze the fabric to achieve warp stretching.

[0035] In this process, after the fabric is heated, it passes over the conveyor roller 4. Two traction wheels 5 press on the two sides of the fabric and rotate in opposite directions to pull the two sides of the fabric away from each other, thus stretching the fabric in the weft direction. The fabric passes between the two tenter rollers 6, which rotate in opposite directions to pull and convey the fabric. In addition, the two tenter rollers 6 squeeze the fabric to achieve warp stretching, so that the fabric is fully stretched in both the warp and weft directions, effectively improving the shaping effect.

[0036] Specifically, each of the two second brackets 12 has a mounting plate 51 on one side close to each other. A drive motor A53 is fixed on each of the two mounting plates 51. A shaft 52 is fixed on the output shaft of each of the two drive motors A53. The two traction wheels 5 are respectively fixed on the ends of the shafts 52 on the corresponding sides. When the drive motor A53 works, its output shaft can drive the shaft 52 to rotate, thereby driving the traction wheel 5 to rotate, providing a stable drive for the traction wheel 5 to rotate and pull the fabric side.

[0037] In addition, a suspension plate 54 is fixed on one side of each of the two second brackets 12 that are close to each other. An adjusting screw 55 is installed in the threaded hole 541 on the suspension plate 54. The bottom ends of the two adjusting screws 55 are rotatably connected to the top of the mounting plate 51 on the corresponding side. The top end of the adjusting screw 55 is provided with a torsion handle 551.

[0038] Guide rods 56 are vertically slidably inserted into the guide holes 542 on both suspension plates 54, and the bottom ends of the two guide rods 56 are fixedly connected to the top of the mounting plates 51 on the corresponding sides.

[0039] By pinching the torsion handle 551 to turn the adjusting screw 55, the rotating adjusting screw 55 engages with the screw hole 541. Combined with the limiting and guiding effect of the guide hole 542 and the guide rod 56, it can drive the mounting plate 51 and the traction wheel 5 to be raised and lowered. Adjusting the traction wheel 5 downwards can press the fabric tightly to ensure sufficient traction friction between the traction wheel 5 and the fabric. Adjusting the traction wheel 5 upwards can make room when changing the fabric for easy operation.

[0040] In addition, the lifting and adjusting mechanism of the traction wheel 5 can be used for fabrics of different thicknesses.

[0041] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. Furthermore, the specific structure, model and coefficient index of all its components are its own technology. As long as it can achieve its beneficial effect, it can be implemented. Therefore, it will not be described in detail.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
