[0004] However, this patent requires adjusting the tension of the yarn when the yarn is loose during transportation. Since the yarn is light in weight, the yarn between the two conveying rollers shakes during transportation, causing the yarn to run away during the tension adjustment process. Based on this, we propose a yarn conveying device. Utility Model Content

[0005] The purpose of the utility model is to provide a yarn conveying device to solve the problem proposed in the above background technology that when the yarn is loose during conveyance, the tension of the yarn needs to be adjusted. Since the yarn is light in weight, the yarn between the two conveying rollers shakes during conveyance, resulting in the yarn running away during the process of adjusting the tension.

[0006] The technical solution of the utility model is: a yarn conveying device, comprising a support frame, a mounting hole is opened at the top of the support frame, a fixing rod is symmetrically fixedly connected inside the mounting hole, the outer walls of two fixing rods are fixedly connected with the same group of placement blocks, and a plurality of the placement blocks are equidistantly arranged one by one;

[0023] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] like Figure 1 - Figure 4 As shown, a yarn conveying device comprises a support frame 1, a mounting hole 2 is opened at the top of the support frame 1, a fixing rod 3 is symmetrically fixedly connected inside the mounting hole 2, and the outer walls of the two fixing rods 3 are fixedly connected to the same group of placement blocks 4, and a plurality of placement blocks 4 are equidistantly arranged one by one;

[0025] A screw rod 5 is embedded in the top of the placement block 4 through a thread, and the bottom end of the screw rod 5 is rotatably connected to a first U-shaped block 7 through a bearing seat 6.

[0026] Furthermore, at the top of the placement block 4, both sides of the outer wall near the screw rod 5 are slidably connected with a moving rod 8 that passes through the top of the first U-shaped block 7, a positioning hole 9 is opened on the top of the moving rod 8, a connecting rope 10 is bonded to the top of the placement block 4, a connecting plate 11 is bonded to one end of the connecting rope 10, and positioning rods 12 are fixedly connected to both sides of one end of the connecting plate 11, a limiting plate 13 is fixedly sleeved at the bottom of the moving rod 8, a supporting spring 14 is sleeved on the outside of the moving rod 8, one end of the supporting spring 14 is fixedly connected to the top of the first U-shaped block 7, and the other end is fixedly connected to the bottom end of the limiting plate 13, and the two moving rods are fixedly connected. The bottom end of the rod 8 is fixedly connected to the same second U-shaped block 15, and a first guide roller 16 is rotatably embedded inside the second U-shaped block 15. A second guide roller 17 is rotatably embedded inside the first U-shaped block 7. The outer walls of the first guide roller 16 and the second guide roller 17 are both provided with guide grooves 18. When the screw 5 is rotated so that the screw 5 rotates clockwise or counterclockwise, the screw 5 drives the first U-shaped block 7 to rise and fall under the restriction of the two moving rods 8 and the action of the bearing seat 6, so as to fine-tune the height of the first U-shaped block 7, which is convenient for adjusting the tension of the yarn during transportation.

[0027] Furthermore, the outer wall of the moving rod 8 is adapted to push the inside of the positioning hole 9. When the two positioning rods 12 are embedded in the two positioning holes 9, the position of the moving rod 8 is restricted, thereby increasing the distance between the second U-shaped block 15 and the first U-shaped block 7, making it convenient to place the yarn in the guide groove 18 on the outer wall of the second guide roller 17 before transportation.

[0028] Furthermore, the overall cross-section of the connecting plate 11 and the two positioning rods 12 is concave, so that when the connecting plate 11 is pulled, the two positioning rods 12 are driven to embed inside the two positioning holes 9, thereby facilitating the subsequent fixation of the position of the second U-shaped block 15.

[0029] Furthermore, a rubber pad is bonded to the outer wall of the fixing rod 3, and the outer wall of the rubber pad fits tightly against the inner wall of the placement block 4. Since the weight of the placement block 4 fits tightly against the rubber pad on the outer wall of the fixing rod 3, the position of the placement block 4 is restricted to prevent the placement block 4 from sliding easily.

[0030] Furthermore, the horizontal plane at the top of the first guide roller 16 is flush with the top surface of the second U-shaped block 15, and the horizontal plane at the bottom of the second guide roller 17 is flush with the bottom surface of the first U-shaped block 7. Since the top surface of the second U-shaped block 15 is in contact with the bottom surface of the first U-shaped block 7, the yarn can only move inside the guide groove 18 during adjustment, thereby avoiding the phenomenon of yarn running.

[0031] Working principle: First, push the two moving rods 8 so that the two moving rods 8 descend and the support spring 14 is compressed. At this time, the moving rod 8 drives the positioning hole 9 to align with the positioning rod 12, and pulls the connecting plate 11, so that the connecting plate 11 embeds the two positioning rods 12 into the two positioning holes 9 under the action of the connecting rope 10, thereby limiting the position of the moving rod 8, thereby increasing the distance between the second U-shaped block 15 and the first U-shaped block 7, and facilitating the placement of the yarn inside the guide groove 18 of the outer wall of the second guide roller 17 before transportation, and pushing multiple placement blocks 4 so that the multiple placement blocks 4 slide along the outer walls of the two fixed rods 3, so that the multiple placement blocks 4 can adjust their positions on the fixed rods 3 according to the conveying position of the yarn, and because the weight of the placement block 4 itself fits tightly with the rubber pad on the outer wall of the fixed rod 3, the position of the placement block 4 is limited to prevent the placement block 4 from sliding easily;

[0032] Secondly, when the tension needs to be adjusted during the yarn conveying process, the positioning rod 12 is pulled out from the positioning hole 9. Due to the reaction force of the support spring 14, the two support springs 14 drive the two moving rods 8 to rise, and the two moving rods 8 drive the second U-shaped block 15 to rise, so that the top surface of the second U-shaped block 15 is in contact with the bottom surface of the first U-shaped block 7. Then, the screw 5 is rotated so that when the screw 5 is driven to rotate clockwise or counterclockwise, the screw 5 drives the first U-shaped block 7 to rise and fall under the restriction of the two moving rods 8 and the action of the bearing seat 6, so as to fine-tune the height of the first U-shaped block 7, so as to facilitate the adjustment of the tension of the yarn during conveying. At this time, since the top surface of the second U-shaped block 15 is in contact with the bottom surface of the first U-shaped block 7, the yarn can only move inside the guide groove 18 during adjustment, so as to avoid the phenomenon of running line.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
