Description

Technical Field

[0001] The utility model relates to the technical field of towel processing, in particular to a yarn guiding device with adjustable tension. Background Art

[0002] Towels are a common household item used for wiping the body, absorbing water or cleaning. Towels are usually made of cotton fibers and have good water absorption and softness. Yarn guide devices are common components in spinning machinery and equipment. They are used to guide the yarn through the correct path during the spinning process to ensure that the yarn can be stretched, twisted and spun smoothly. In the towel processing process, yarn guide devices are usually required.

[0003] Some existing yarn guiding devices are not easy to control the tension of the yarn during the yarn guiding process, which makes the yarn easily too loose or too tight, and the stability is relatively poor. In addition, the two conveying rollers of this type of yarn guiding device are usually integrated, and it is troublesome to adjust the distance between the conveying rollers. When guiding other yarns, other types of guiding devices need to be used, which has low practicality.

[0004] Therefore, those skilled in the art provide a yarn guiding device with adjustable tension to solve the problems raised in the above background technology. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-6 The utility model provides an embodiment: a tension-adjustable yarn guide device, comprising a guide mechanism 1, two fixing mechanisms 2 and a positioning mechanism 3, wherein the guide mechanism 1 comprises a bottom plate 101, two first support plates 102, two second support plates 106, two motors 105, two first conveying rollers 107 and two second conveying rollers 108, the upper end surfaces of the two first support plates 102 and the two second support plates 106 are both penetrated by a lifting plate 103 which is slidably arranged, a belt 109 is arranged between one side of the outer end surfaces of the two first conveying rollers 107 and the two second conveying rollers 108, and the two first support plates 102 are respectively fixedly arranged on the bottom plate On the front side of the upper end surface of the bottom plate 101, two second support plates 106 are respectively fixedly arranged on the rear side of the upper end surface of the bottom plate 101, one of the two first support plates 102 and one of the four lifting plates 103 are respectively fixedly connected to the two motors 105 through the load-bearing plate 104, two first conveying rollers 107 are respectively rotatably arranged between the end surfaces of the two first support plates 102 and the two second support plates 106 on one side, two second conveying rollers 108 are respectively rotatably arranged between the end surfaces of the four lifting plates 103 on one side opposite to each other, and the two first conveying rollers 107 and one of the two second conveying rollers 108 on one side are respectively fixedly connected to the output ends of the two motors 105.

[0035] By passing the yarn between the two front conveying rollers, then passing the passed yarn through the lower end of the positioning plate 304, and finally passing the yarn between the two rear conveying rollers, when the two motors 105 are working, the first conveying roller 107 and the second conveying roller 108 are driven to rotate in opposite directions, so that the same direction of force can be applied to the yarn between the two, driving the yarn to move, and when the two front conveying rollers rotate, the two rear conveying rollers can be driven to rotate together through the action of the belt 109.

[0036] The two fixing mechanisms 2 include two H-shaped plates 201, two L-shaped plates 202 and two inclined plates 203. The first U-shaped plates 205 are slidably arranged on the lower sides of the front and rear end surfaces of the two L-shaped plates 202. Two first return springs 206 are fixedly arranged between the four first U-shaped plates 205 and the two L-shaped plates 202. A plurality of fixing blocks 207 are fixedly arranged on the upper sides of the end surfaces on the opposite sides of the two H-shaped plates 201. The two H-shaped plates 201 are fixedly arranged at the middle positions on both sides of the upper end surface of the bottom plate 101, respectively. The two L-shaped plates 202 are slidably arranged on the upper sides between the front and rear inner walls of the two H-shaped plates 201, and the two inclined plates 203 are fixedly connected to the two L-shaped plates 202, respectively. The two ends of the two inclined plates 203 are fixedly connected to the four lifting plates 103 through the connecting plates 204. When the distance between the first conveying roller 107 and the second conveying roller 108 needs to be changed, the first U-shaped plates 205 are squeezed in two directions while moving upward. When they move to a suitable position, the squeezing of the first U-shaped plates 205 is released. At this time, the protrusions of the first U-shaped plates 205 enter the inner wall of the fixed block 207, thereby fixing the L-shaped plate 202. During the movement of the L-shaped plate 202, under the action of the inclined plate 203 and the connecting plate 204, the four lifting plates 103 are driven to move upward together, thereby driving the two second conveying rollers 108 to move upward.

[0037] The fixed mechanism includes an electric telescopic rod 301, a second U-shaped plate 302, a rotating rod 303, three positioning plates 304 and a slider 305. A lower pull-down plate 306 is slidably provided on the lower end surface of the slider 305. Two second return springs 307 are fixedly provided between the lower pull-down plate 306 and the slider 305. The electric telescopic rod 301 is embedded in the middle position of the upper end surface of the bottom plate 101. The middle position of the lower end surface of the second U-shaped plate 302 is fixedly connected to the output end of the electric telescopic rod 301. The rotating rod 303 is rotatably provided on the upper side between the inner walls on the opposite side of the second U-shaped plate 302. The three positioning plates 304 are fixed to the rotating rod 303. The slider 305 is slidably set on a lower inner wall on one side of the two H-shaped plates 201. By pulling the lower pull-down plate 306 downward while rotating the rotating rod 303, the rotating rod 303 is rotated to a suitable position according to the markings on the surface of the rotating rod 303 and the pointer on the surface of the slider 305. At this time, the pull on the lower pull-down plate 306 is released. Under the action of the second reset spring 307, the protrusion on the surface of the lower pull-down plate 306 enters into the inner wall of the rotating rod 303, thereby fixing the rotating rod 303. The distances between the baffles on the surfaces of the three positioning plates 304 are different, so that it can block a variety of yarns.

[0038] Working principle: manually pass the yarn between the two front conveying rollers, then place the yarn between the partitions under the positioning plate 304, and finally pass the yarn between the two rear conveying rollers. After placing it, turn on the electric telescopic rod 301 to drive the positioning plate 304 to move, so as to adjust the degree of folding and deformation of the yarn. After multiple yarns are placed, turn on the motor 105, and the motor 105 drives the first conveying roller 107 and the second conveying roller 108 to rotate in different directions. When other yarns are to be placed, the four first U-shaped plates 205 are squeezed toward the middle in pairs while moving upward. When moving to the appropriate position, release the squeezing of the first U-shaped plate 205, and finally pull the lower pull plate 306 downward while rotating the rotating rod 303. When it rotates to the appropriate position, release the pull on the lower pull plate 306.
