Description

Technical Field

[0001] The utility model relates to the technical field of textile, in particular to a warp knitting machine yarn tension control mechanism. Background Technique

[0002] When the yarn passes through the warp knitting machine for textile, it needs to maintain a certain tension to ensure quality and efficiency. Maintaining appropriate tension is a necessary condition in the spinning process, which helps the yarn to have a good shape, improve the winding density, and enhance the physical and mechanical properties of the yarn.

[0003] The yarn needs to be humidified during the textile process. Appropriate humidity can reduce fiber damage caused by dryness or excessive wetness of the yarn, make the surface of the yarn smoother, and the color more vivid. Reduce static electricity. Although the current yarn tension control mechanism can keep the yarn at a certain tension, it does not have the function of humidifying the yarn, and the function is relatively single. At present, the yarn is usually humidified by spraying. Although the humidification speed is fast, it will cause the surrounding working environment to be wet and humid, which is not conducive to the storage of machinery and equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a warp knitting machine yarn tension control mechanism to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a warp knitting machine yarn tension control mechanism, including: a bottom plate, mounting brackets installed at both ends of the outer wall of the top of the bottom plate, and fixed rollers rotatably installed on the two mounting brackets. It also includes: a vertical plate fixed to one end of the outer wall of the top of the bottom plate, a chute is opened on one side outer wall of the vertical plate, and a lifting assembly is rotatably installed on the outer wall of the top of the vertical plate. One end of the lifting assembly is installed with a dripping assembly, and elastic components are installed on both outer walls of the dripping assembly. A humidifying assembly is rotatably installed on the outer walls of the two elastic components facing each other, and a controller is installed on the outer wall of one of the elastic components.

[0006] The lifting assembly includes a threaded rod, a slider screwed on the threaded rod, and a connecting plate fixed to one end of the slider.

[0007] The dripping assembly includes a water tank, a non-contact liquid level sensor installed on one side outer wall of the water tank, a cotton block placed at the bottom of the water tank, and a cotton thread connected to the bottom of the cotton block.

[0008] The elastic component includes a housing, a movable plate slidably connected to the inner wall of the housing, and a compression spring arranged in the housing.

[0009] The humidifying assembly includes a movable roller and a sponge sleeve installed on the movable roller.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

It further includes: a vertical plate 4 fixed to one end of the outer wall of the top of the bottom plate 1, a chute 5 opened on one side outer wall of the vertical plate 4, and a lifting assembly 6 rotatably installed on the outer wall of the top of the vertical plate 4. One end of the lifting assembly 6 is installed with a water dripping assembly 7, and elastic components 8 are installed on both outer walls of the water dripping assembly 7. A humidifying assembly 9 is rotatably installed on the opposite side outer walls of the two elastic components 8, and a controller 10 is installed on the outer wall of one of the elastic components 8.

[0021] It should be noted here that: a certain amount of water can be loaded into the water dripping assembly 7, the yarn 11 can be passed through the previous fixed roller 3, the lifting assembly 6 can be used to drive the water dripping assembly 7 to descend, and then drive the humidifying assembly 9 to descend, pressing down a part of the yarn 11, so that the yarn 11 maintains a certain tension. The elastic components 8 provided can play a buffering role when the humidifying assembly 9 descends and presses on the yarn 11. The water in the water dripping assembly 7 can slowly drip down and drip on the humidifying assembly 9. When the yarn 11 is transported during textile production, it contacts the humidifying assembly 9, thereby humidifying the yarn 11, making the function of the device better. At the same time, when humidifying the yarn 11, it will not cause the surrounding working environment to be wet and humid.

[0022] In a preferred embodiment, the lifting assembly 6 includes a threaded rod 601, a slider 602 screwed onto the threaded rod 601, and a connecting plate 603 fixed to one end of the slider 602.

[0023] It should be noted here that: the threaded rod 601 can be rotated to make the slider 602 descend, and then drive the connecting plate 603 to descend.

[0024] In a preferred embodiment, the water dripping assembly 7 includes a water tank 701, a non-contact liquid level sensor 702 installed on one side outer wall of the water tank 701, a cotton block 703 placed at the bottom of the water tank 701, and a cotton thread 704 connected to the bottom of the cotton block 703.

[0025] It should be noted here that: water can be poured into the water tank 701, the cotton block 703 and the cotton thread 704 are wetted by the water, and the water slowly drips downward through the cotton thread 704 and drips on the humidifying assembly 9. The non-contact liquid level sensor 702 provided can detect the water level in the water tank 701. When the detected water level is low and the water is almost used up, the non-contact liquid level sensor 702 transmits a signal to the controller 10, and the controller 10 alarms to remind the staff to add water to the water tank 701 in time.

[0026] In a preferred embodiment, the elastic component 8 includes a housing 801, a movable plate 802 slidably connected to the inner wall of the housing 801, and a compression spring 803 provided in the housing 801.

[0027] It should be noted here that: during the descending process of the humidifying component 9, it contacts the yarn 11, driving the movable plate 802 to extend into the housing 801 and squeezing the spring 803.

[0028] In a preferred embodiment, the humidifying component 9 includes a moving roller 901 and a sponge sleeve 902 mounted on the moving roller 901.

[0029] It should be noted here that: the water dripping down through the cotton thread 704 can drip onto the sponge sleeve 902 and be absorbed by the sponge sleeve 902, making the sponge sleeve 902 become moist, and then humidifying the yarn 11.

[0030] Working principle: Water can be poured into the water tank 701. The water wets the cotton block 703 and the cotton thread 704, and the water slowly drips downward through the cotton thread 704. The yarn 11 can be passed through the upper fixed roller 3. The threaded rod 601 can be rotated to make the slider 602 descend, thereby driving the connecting plate 603 to descend, further driving the water tank 701 to descend, further driving the moving roller 901 to descend, pressing down a part of the yarn 11 to keep the yarn 11 under a certain tension. During the descending process of the moving roller 901, it contacts the yarn 11, driving the movable plate 802 to extend into the housing 801 and squeezing the spring 803, which can play a buffering role when the moving roller 901 descends and presses on the yarn 11. The water dripping down through the cotton thread 704 can drip onto the sponge sleeve 902 and be absorbed by the sponge sleeve 902, making the sponge sleeve 902 become moist. When the yarn 11 is being woven and conveyed, it contacts the sponge sleeve 902, thereby humidifying the yarn 11, making the function of the device better. At the same time, when humidifying the yarn 11, it will not cause the surrounding working environment to be wet. The non-contact liquid level sensor 702 can detect the water level in the water tank 701. When it detects that the water level is low and the water is almost used up, the non-contact liquid level sensor 702 transmits a signal to the controller 10, and the controller 10 alarms to remind the staff to add water to the water tank 701 in time, which is more intelligent.
