Abstract
Description
Technical Field
[0001] The utility model relates to the field of weaving equipment, and specifically relates to a device for controlling the balance of the weft tension in weaving. Background Art
[0002] Weaving equipment refers to the equipment that makes the yarn made by the spinning equipment into grey cloth or finished cloth through processes such as warping preparation, weaving, and finishing. These equipment include warping machines, sizing machines, looms, etc. Among them, the loom is the core equipment, which is responsible for weaving the warp and weft of two mutually perpendicular systems into grey cloth or finished cloth according to certain rules. There are many types of weaving equipment, which are mainly divided into two categories: shuttle looms and shuttleless looms. Shuttle looms use shuttles to carry the weft yarn through the warp yarn, while shuttleless looms carry out weaving by means of jet, rapier, projectile, etc., improving the efficiency and quality of weaving.
[0003] However, the following problems still exist in the operation of the existing weaving equipment:
[0004] The tensioning devices used in the existing weaving equipment during the conveying process of the yarn generally form tension by staggering several yarn guide wheels. The tension adjustment process is complex and difficult, and some even cannot adjust the tension. It is difficult to meet the requirements of different tensions during the processing of different types of roving. At the same time, during the processing of roving, the equipment fluctuates greatly, easily causing the yarn to shake, thus causing the tightness degree of the yarn during the conveying process to change, resulting in large tension fluctuations, which greatly affects the normal operation of the equipment and the stability of the product quality. Therefore, it is very necessary to involve a device for controlling the balance of the weft tension in the existing weaving equipment field. Summary of the Utility Model
[0005] In order to make up for the deficiencies of the existing technology and solve the problem that it is difficult to meet the requirements of different tensions during the processing of different types of roving, the utility model proposes a device for controlling the balance of the weft tension in weaving.

[0029] The following will further elaborate on this application in conjunction with the attached Figure 1 —4.
[0030] The embodiments of this application disclose a device for controlling the balance of the weft tension in weaving. Referring to Figure 1 - Figure 3 , a device for controlling the balance of the weft tension in weaving includes a base 10, on which conveying frames 11 are symmetrically and fixedly assembled. Between the two conveying frames 11, a transmission rod 12 is symmetrically and fixedly assembled. On the transmission rod 12, conveying rollers 13 are movably assembled. On each conveying roller 13, a first conveying groove 20 is provided. The first conveying grooves 20 on the two conveying rollers 13 are close to each other. On the side surfaces of the conveying frames 11, assembly rods 33 are movably assembled. At one end of each assembly rod 33, a guiding plate 21 is fixedly assembled. Between the two guiding plates 21, a connecting rod 23 is fixedly assembled. On the connecting rod 23, an adjusting roller 30 is movably assembled. On the adjusting roller 30, a second conveying groove 31 is provided. The adjusting roller 30 is located on one side of the two conveying rollers 13. A torsion spring 40 is fixedly assembled between the conveying frame 11 and the guiding plate 21. The assembly rod 33 is assembled inside the torsion spring 40. On each guiding plate 21, a mounting rod 22 is fixedly assembled. On the side surfaces of the conveying frames 11, fixing blocks 41 are symmetrically and fixedly assembled. Between the two fixing blocks 41, guide rods 42 are symmetrically and fixedly assembled. On the two guide rods 42, a traction block 43 is movably assembled. A telescopic spring 51 is fixedly assembled between the traction block 43 and the fixing block 41. The guide rods 42 are assembled inside the telescopic spring 51. On each traction block 43, an operating rod 50 is fixedly assembled. On each operating rod 50, an adjusting block 32 is movably assembled. The other end of the adjusting block 32 is movably assembled with the mounting rod 22. The yarn moves through the second conveying groove 31 on the adjusting roller 30 and the first conveying grooves 20 on the two conveying rollers 13. As the tightness of the yarn varies, the force on the first conveying groove 20 is different. Under the elastic force of the torsion spring 40 and the telescopic spring 51, the tension of the yarn is balanced, facilitating the conveying of the yarn.
[0031] Referring to Figure 3 and Figure 4, an operation block 52 is fixedly assembled at the bottom of the fixed block 41. The operation block 52 is located below the telescopic spring 51. A rotation cavity 61 is provided inside the knob 53. Traction cavities 62 are symmetrically arranged on the rotation cavity 61. A threaded sleeve rod 60 is movably assembled on the rotation cavity 61. One end of the threaded sleeve rod 60 movably penetrates through the operation block 52 and the fixed block 41 to between the two telescopic springs 51. And symmetrically fixed assemblies of sliding blocks 63 that move in the traction cavities 62 are arranged on the lower part of the surface of the threaded sleeve rod 60. A transmission lead screw 70 that is threadedly assembled with the threaded sleeve rod 60 is movably assembled on the rotation cavity 61. One end of the transmission lead screw 70 movably penetrates through the operation block 52. And a knob 53 is fixedly assembled at one end of the transmission lead screw 70. The knob 53 is located below the operation block 52. When the device stops running, twist the knob 53 to make the transmission lead screw 70 rotate in the threaded sleeve rod 60, so that the sliding block 63 moves on the traction cavity 62. The threaded sleeve rod 60 pushes the traction block 43 upward, which helps to restore the elastic deformation of the telescopic spring 51 and the torsion spring 40, and improves the service life of the device.
[0032] Working principle: The yarn moves through the second conveying groove 31 on the adjusting roller 30 and the first conveying grooves 20 on the two conveying rollers 13. As the tightness of the yarn is different, the force on the first conveying groove 20 is different. Under the elastic action of the torsion spring 40 and the telescopic spring 51, the tension of the yarn is balanced, which is convenient for conveying the yarn. When the device stops running, twist the knob 53 to make the transmission lead screw 70 rotate in the threaded sleeve rod 60, so that the sliding block 63 moves on the traction cavity 62. The threaded sleeve rod 60 pushes the traction block 43 upward, which helps to restore the elastic deformation of the telescopic spring 51 and the torsion spring 40, and improves the service life of the device.
[0033] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
