Abstract
Description
Technical Field
[0001] This utility model relates to a tension mechanism, specifically an adaptive tension mechanism for a widening and setting machine, and belongs to the technical field of widening and setting machines. Background Technology
[0002] A fabric stretching and setting machine is a piece of equipment used in the textile industry. It is mainly used to stretch and set fabrics. It stretches and fixes the fabric through mechanical devices to achieve the required width and shape, and maintains its stability through processes such as heating and cooling. Most existing machines use threaded stretching rollers for stretching. When the fabric shrinks in the weft direction under the action of warp tension and adheres tightly to the outer side of the thread, the fabric is subjected to the normal support force of the thread side. After decomposition, the weft component force is the stretching force on the fabric, thereby achieving the stretching of the fabric.
[0003] Existing widening and setting machines typically include a tension mechanism to maintain a certain tension on the fabric during processing to achieve high-quality results. However, when using different fabrics, the different materials and external friction forces result in variations, while the fabric's movement speed remains constant. This can easily lead to excessive or insufficient tension. Excessive tension may cause fabric breakage and accelerated equipment wear, while insufficient tension may cause the fabric to slip or deviate from its intended path, affecting the processing effect. To address these issues, we provide an adaptive tension mechanism for widening and setting machines. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides an adaptive tension mechanism for a widening and setting machine, the specific technical solution of which is as follows:
[0005] An adaptive tension mechanism for a widening and setting machine includes a housing, a drive mechanism inside the housing, a pressing mechanism on one side of the drive mechanism, a tension roller slidably connected to the inner wall of the housing, a first adjusting plate rotatably connected to the outer surface of the tension roller, an elastic mechanism above the first adjusting plate, a threaded rod fixedly connected to the upper surface of the first adjusting plate, two detection mechanisms on the outer surface of the threaded rod, a guide mechanism on one side of the housing, a controller mounted on the outer surface of the housing, and a top plate fixedly connected to the upper surface of the housing.
[0006] Preferably, the drive mechanism includes an electric motor, which is mounted outside the housing. The output end of the electric motor passes through the housing and is connected to a rotating roller. The end of the rotating roller is rotatably connected to the housing.
[0007] Preferably, the extrusion mechanism includes an extrusion roller, a second adjusting plate is rotatably connected to the outer surface of the extrusion roller, and an adjusting rod is rotatably connected to one side of the second adjusting plate.
[0008] Preferably, the outer surface of the adjusting rod is threaded to the housing, the inner wall of the housing is provided with a sliding groove, and the end of the extrusion roller is located inside the sliding groove and is slidably connected thereto.
[0009] Preferably, the elastic mechanism includes a sliding rod, the bottom of which is connected to a first adjusting plate, the outer surface of which is slidably connected to a top plate, and a spring sleeved on the outer surface of which is connected to the top plate at its upper end and to the first adjusting plate at its lower end.
[0010] Preferably, the detection mechanism includes an adjusting sleeve, the inner wall of which is threadedly connected to a threaded rod, a fixing block is connected to one end of the adjusting sleeve, a pressure sensor is installed on the side of the fixing block away from the adjusting sleeve, and the outer surface of the threaded rod is slidably connected to the top plate.
[0011] Preferably, a fixing plate is connected to one side of the housing, and a guide roller is rotatably connected to the inner wall of the fixing plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The adaptive tension mechanism of this widening and setting machine, through the setting of a drive mechanism and tension rollers, adjusts the positions of the two detection mechanisms according to the required tension of different fabrics. In actual use, when the tension is too high or too low, the tension of the fabric is greater than or less than the elasticity of the elastic mechanism, causing the tension roller to move up or down. This causes the upper or lower detection mechanism to be squeezed against the top plate. Then, the controller changes the power of the drive mechanism to adjust the movement speed of the fabric, thereby adjusting the tension of the fabric and keeping it within a suitable range. This achieves the effect of self-adjusting the fabric tension, thus solving the problem that the existing fabric movement speed is fixed, which easily leads to excessive or insufficient tension and affects the processing effect.
[0014] 2. The adaptive tension mechanism of this widening and setting machine, through the setting of components such as the extrusion mechanism, allows the position of the extrusion roller to be adjusted by turning the adjusting rod, thereby adjusting the distance between the extrusion roller and the rotating roller to suit fabrics of different thicknesses. The guide roller can guide the fabric, which passes through the upper part of the guiding mechanism and the lower part of the tension roller. In conjunction with the drive mechanism, the fabric is made to form a V-shape, so as to facilitate the detection of the fabric tension. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.
[0022] Please see Figures 1-5 The device includes a housing 1, a drive mechanism 2 inside the housing 1, a pressing mechanism 3 on one side of the drive mechanism 2, a tension roller 4 slidably connected to the inner wall of the housing 1, a first adjusting plate 5 rotatably connected to the outer surface of the tension roller 4, an elastic mechanism 6 above the first adjusting plate 5, a threaded rod 7 fixedly connected to the upper surface of the first adjusting plate 5, two detection mechanisms 8 on the outer surface of the threaded rod 7, a guide mechanism 9 on one side of the housing 1, a controller 10 mounted on the outer surface of the housing 1, and a top plate 11 fixedly connected to the upper surface of the housing 1. The drive mechanism 2 provides a driving force for the fabric to move forward. The extrusion mechanism 3 squeezes the fabric to allow it to pass through at a uniform speed, increasing the friction between the fabric and the drive mechanism 2. The extrusion mechanism 3 can be adjusted according to the thickness of the fabric. The fabric passes through the upper part of the guide mechanism 9 and the lower part of the tension roller 4, and then, in conjunction with the drive mechanism 2, the fabric forms a V-shape. The housing 1 is provided with a rectangular groove for the tension roller 4 to slide up and down. The tension roller 4 is provided with two annular recesses for placing the first adjusting plate 5. The first adjusting plate 5 consists of two rings and a flat plate. When the tension roller 4 rotates, the first adjusting plate 5 does not move, and the two rings are located in the recesses of the tension roller 4, so they will not rub against the fabric.
[0023] The drive mechanism 2 includes a motor 201, which is installed outside the housing 1. The output end of the motor 201 passes through the housing 1 and is connected to a rotating roller 202. The end of the rotating roller 202 is rotatably connected to the housing 1. The motor 201 can drive the rotating roller 202 to rotate so as to move the external fabric.
[0024] The extrusion mechanism 3 includes an extrusion roller 301. A second adjusting plate 302 is rotatably connected to the outer surface of the extrusion roller 301. An adjusting rod 303 is rotatably connected to one side of the second adjusting plate 302. The second adjusting plate 302 has the same effect as the first adjusting plate 5.
[0025] The outer surface of the adjusting rod 303 is threaded to the housing 1. The inner wall of the housing 1 is provided with a sliding groove 304. The end of the squeezing roller 301 is located inside the sliding groove 304 and is slidably connected thereto. By turning the adjusting rod 303, the position of the squeezing roller 301 can be adjusted, thereby adjusting the distance between the squeezing roller 301 and the rotating roller 202 to suit fabrics of different thicknesses.
[0026] The elastic mechanism 6 includes a sliding rod 601. The bottom of the sliding rod 601 is connected to the first adjusting plate 5. The outer surface of the sliding rod 601 is slidably connected to the top plate 11. A spring 602 is sleeved on the outer surface of the sliding rod 601. The upper end of the spring 602 is connected to the top plate 11, and the lower end of the spring 602 is connected to the first adjusting plate 5. The spring 602 can give the first adjusting plate 5 a downward elastic force, thereby causing the tension roller 4 to drive the fabric to move downward. The greater the tension of the fabric, the more severely the tension roller 4 is squeezed, and the higher the position of the tension roller 4 is, and vice versa.
[0027] The detection mechanism 8 includes an adjusting sleeve 801, the inner wall of which is threadedly connected to the threaded rod 7. One end of the adjusting sleeve 801 is connected to a fixing block 802. A pressure sensor 803 is installed on the side of the fixing block 802 away from the adjusting sleeve 801. The outer surface of the threaded rod 7 is slidably connected to the top plate 11. The two detection mechanisms 8 are respectively set above and below the top plate 11. By turning the adjusting sleeve 801, the position of the two adjusting sleeves 801 can be adjusted, thereby adjusting the amplitude and range of the threaded rod 7's up and down movement.
[0028] A fixing plate 901 is connected to one side of the housing 1. A guide roller 902 is rotatably connected to the inner wall of the fixing plate 901. The guide roller 902 can guide the fabric.
[0029] The electric motor 201, pressure sensor 803, and controller 10 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures, and they can be replaced by other devices with the same function.
[0030] In use, the fabric, after being expanded, passes between the upper part of the guide mechanism 9 and the lower part of the tension roller 4. The drive mechanism 2 then forms a V-shape, propelling the fabric forward and expanding its width. When the fabric moves too fast, the tension is too high; when the fabric moves too slow, the tension is too low. The positions of the two detection mechanisms 8 are adjusted according to the required tension for different fabrics. In actual use, when the tension is too high, the fabric tension exceeds the elasticity of the elastic mechanism 6, causing the tension roller 4 to move upwards, thus allowing the lower part of the tension roller to move upwards. When the detection mechanism 8 is pressed against the top plate 11, the pressure sensor 803 detects the pressure and transmits the signal to the controller 10. The controller 10 controls the power of the motor 201 to be reduced, thereby slowing down the speed of the motor 201 and reducing the movement speed of the fabric, thus reducing the tension of the fabric. When the tension of the fabric is too low, the upper detection mechanism 8 contacts the top plate 11, and the motor 201 increases its rotation speed to adjust the movement speed of the fabric, thereby adjusting the tension of the fabric and keeping the tension of the fabric within a suitable range, thus achieving the effect of self-adjusting the tension of the fabric.
