Description

Technical Field

[0001] The utility model relates to the technical field of yarn tensioning, and particularly relates to a yarn tensioning device. Background Art

[0002] A yarn is a textile product processed from various textile fibers into a product with a certain fineness, and is used for weaving, rope making, thread making, knitting, embroidery, etc. It is divided into short fiber yarns, continuous filaments, etc. During the yarn production process, a yarn tensioning device can tension the yarn in real time according to the working conditions, thereby ensuring the stability of the yarn tension and guaranteeing the production efficiency and product quality.

[0003] A prior yarn tensioning device can be specifically referred to a tensioning device for a yarn with an application number of: CN202123268662.1, which includes a column body, a first tensioning assembly and a second tensioning assembly. An installation plate is arranged at the top of the column body, a base is arranged at the bottom of the column body, the first tensioning assembly is arranged on one side of the installation plate, and the second tensioning assembly is arranged on the other side of the installation plate; during the actual textile production process, when the whole device needs to be used, the yarn can be attached to the second tensioning assembly and wound around the outer surface of the column body according to the degree of tension required. Subsequently, the yarn is attached to two pulleys. When the yarn needs to be tensioned, the first connecting rod can be rotated to drive the tensioning arm to rotate. Subsequently, the tensioning arm drives the pulley to tighten the yarn, and the tensioning force can be adjusted according to the rotation amplitude of the tensioning arm. Thus, the tensioning force can be conveniently adjusted according to different yarns without using different tensioning devices, improving the adaptability of the whole device.

[0004] Since the above device does not have a component for protecting the yarn, when adjusting the yarn tension degree, if the stretching force is too large, because there is no component for protecting the yarn, it is very easy to cause the yarn to break, thereby reducing the work efficiency.

The bottom end of the threaded rod 11 is welded to the top end of the rotating handle 12, and the top end of the threaded rod 11 is welded to the bottom end of the rotating block 13. The outside of the rotating block 13 is sleeved with a second fixing block 14, and the rotating block 13 is rotatably connected to the second fixing block 14. The top end of the second fixing block 14 is welded to the bottom end of the first fixing plate 15. One side of the first fixing plate 15 is welded to one side of the third fixing block 16. The bottom end of the third fixing block 16 is welded to the top end of the guide rod 17. One side of the first fixing block 10 near the front end position is welded to one side of the fourth fixing block 18. The fourth fixing block 18 is sleeved outside the guide rod 17, and the fourth fixing block 18 is slidably connected to the guide rod 17. At both sides of the top end of the first fixing plate 15, there are sleeve rods 19, and the top end of the first fixing plate 15 is welded to the bottom end of the sleeve rod 19. A moving rod 21 is inserted inside the sleeve rod 19, and the sleeve rod 19 is slidably connected to the moving rod 21.

The bottom end inside the sleeve rod 19 is welded to the bottom end of the return spring 20, and the top end of the return spring 20 is welded to the bottom end of the sleeve rod 19.

[0025] Please refer to Figure 5 and Figure 6 , the top end of the second fixing plate 22 is welded to the bottom end of the fifth fixing block 23. At the left and right ends of the front end of the third fixing plate 1, there are fixing frames 28 provided at the same time, and the front end of the third fixing plate 1 is welded to the rear end of the fixing frame 28. At the rear ends of the fifth fixing block 23 and the fixing frame 28, there are also fixing rods 24 provided, and the rear ends of the fifth fixing block 23 and the fixing frame 28 are respectively welded to the front ends of the fixing rods 24.

The guide rod 17 at the bottom of the third fixed block 16 moves downward along the inside of the fourth fixed block 18, and at the same time drives the first fixed plate 15 to move downward, and the first fixed plate 15 drives the roller 25 at the upper position of the second fixed plate 22 to move downward, and tighten the yarn. If the tightening force is large, the return spring 20 inside the sleeve rod 19 will pull and extend, and drive the moving rod 21 to move outward along the inside of the return spring 20, so that the tension can be buffered to protect the yarn, and it is used to protect the parallel yarn when adjusting the tension force;

[0027] When the roller needs to be removed, the limit block 27 is first rotated to drive the bolt head 26 to rotate along the inside of the fixing rod 24 and move outward until the bolt head 26 is completely separated from the inside of the fixing rod 24. The roller 25 can be pulled outward until it is completely separated from the surface of the fixing rod 24 at one end of the fifth fixing block 23, and the roller can be removed. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
