[0002] Yarn clamping pieces are mainly used in textiles. By cooperating with yarn clamping rods or yarn clamping seats, they can clamp the weft yarn and ensure the quality and production efficiency of the fabric.

[0003] The design of textile clamps needs to take into account many factors, such as the thickness, material, tension of the yarn and the running speed of the textile machinery. Its clamping surface needs to be able to firmly clamp the yarn to prevent the yarn from sliding or falling off during the textile process.

DETAILED DESCRIPTION

[0035] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0036] The utility model embodiment specifically provides a warping aluminum yarn sandwich sheet, please refer to Figure 1 , including a mounting plate 1, a yarn clamping piece 2 and a tensioning component 3.

[0037] The yarn clamping piece 2 is installed on the mounting plate 1, and the yarn clamping piece 2 includes a first clamping piece 21 and a second clamping piece 22 which are attached to each other. The bottom end of the first clamping piece 21 is fixed to the mounting plate 1, and the second clamping piece 22 is movable. The weft yarn is clamped by the adjacent surfaces of the first clamping piece 21 and the second clamping piece 22.

[0038] For details, please refer to Figure 1 and Figure 2 The tensioning assembly 3 is installed on the first clamp 21 and the second clamp 22. The tensioning assembly 3 includes a mounting rod 31 and a tensioning mechanism 32. The mounting rod 31 is coaxially arranged with the first clamp 21 and the second clamp 22. The tensioning mechanism 32 is arranged on the mounting rod 31 to adjust the movable spacing between the adjacent surfaces of the first clamp 21 and the second clamp 22 through the tensioning mechanism 32 to adjust the clamping tightness of weft yarns of different thicknesses.

[0039] During implementation, the first clamp 21 and the second clamp 22 are made of aluminum, which has a smooth surface and is light in weight, and can meet the need for convenient sliding of the weft yarn. Compared with some rubber clamps, it can also reduce sliding wear of the sheet body and increase service life.

[0040] The outer wall of the mounting rod 31 is in sliding contact with the first clamping piece 21 and the second clamping piece 22, so that the second clamping piece 22 can slide up and down along the outer side of the mounting rod 31, so that when the weft yarn is threaded and slid, the second clamping piece 22 can be pressed down by its own weight to cooperate with the first clamping piece 21 to clamp the weft yarn;

[0041] Further, as a first achievable implementation of the tensioning mechanism 32 in the present technical solution, please refer to Figure 2 and Figure 3 The tensioning mechanism 32 includes a tensioning ring 33, which is arranged above the second clamping piece 22 and fixed to the outer side of the mounting rod 31, so that the upward movement height of the second clamping piece 22 is limited by the tensioning ring 33, so as to adjust the distance between the first clamping piece 21 and the second clamping piece 22, so that the clamping tension of the two clamps on the weft yarn can be controlled;

[0042] When in use, in the process of clamping thinner weft yarns, the downward clamping can be completed only by the deadweight of the second clamp 22. When clamping thicker weft yarns, the second clamp 22 is forced to move upward. At this time, it is affected by the limiting effect of the tensioning ring 33, so that when the weft yarn is threaded, the second clamp 22 stops moving upward and cooperates with the first clamp 21 to clamp the thicker yarn, thereby completing the stable clamping effect of yarns of different thicknesses.

[0043] The cam 322 is provided with a screw thread groove 311 at the bottom of the mounting plate 31, and the tensioning mechanism 32 further includes a cylinder body 321, a bolt 322 and a column groove 323. The outer side of the cylinder body 321 is fixed to the mounting plate 1, and the bolt 322 is coaxially arranged on the cylinder body 321, and the top of the bolt 322 is threadedly connected to the screw thread groove 311, so that the bolt 322 applies force to the screw thread groove 311 by rotating the bolt 322 to meet the installation and fixation of the mounting plate 1 on the mounting plate 1. The inner wall of the cylinder body 321 is provided with a column groove 323, and the outer wall of the mounting rod 31 slides up and down along the column groove 323 in a straight line, so that the up and down height of the tensioning ring 33 is driven by the up and down displacement of the mounting rod 31, so that the upward movable stroke of the second clamp 22 is controlled by the tensioning ring 33, so as to quickly control the movable spacing between the two clamps and control the tension of the weft clamping.

[0044] Furthermore, an auxiliary part is provided on the mounting rod 31 to help the mounting rod 31 slide up and down in a straight line. When the bolt 322 is rotated, in order to prevent the mounting rod 31 from synchronously rotating circumferentially in the column groove 323, the auxiliary part can keep the mounting rod 31 circumferentially fixed, so that the mounting rod 31 can stably move up and down.

[0045] As the first achievable implementation method of the auxiliary component in this technical solution, please refer to Figure 1 The auxiliary part is a fixing button 34 fixed to the top of the mounting rod 31, and the outer contour of the fixing button 34 is polygonal, or an anti-slip structure is provided on the outer side of the fixing button 34, so that when the bolt 322 rotates, the fixing button 34 can be held by hand to prevent the mounting rod 31 from circumferential rotation.

[0046] As a second achievable implementation method of the auxiliary component in this technical solution, please refer to Figure 2 The auxiliary parts include a limit strip 35 integrally fixed on the inner side of the column groove 323 and a slide groove 36 opened on the outer side of the mounting rod 31. The limit strip 35 and the slide groove 36 extend along the height direction of the column groove 323 and the mounting rod 31 respectively. The inner wall of the slide groove 36 slides up and down along the limit strip 35 in a straight line, so that when the threaded groove 311 in the mounting rod 31 is subjected to the spiral push-pull force of the bolt 322, it can be moved up and down along the limit strip 35 in a straight line through the slide groove 36.

[0047] During implementation, a mounting hole 11 is opened on the mounting plate 1 , and the outer wall of the cylinder 321 is fixedly connected to the mounting hole 11 to meet the need for stable installation of the cylinder 321 .

[0048] Further, as a second achievable implementation of the tensioning mechanism 32 in the present technical solution, please refer to Figure 4 The tensioning mechanism 32 includes a threaded column 41, a rotary block 42 and a limit frame 43. The threaded column 41 is coaxially fixed to the top of the mounting rod 31. The interior of the rotary block 42 is threadedly connected to the threaded column 41. The top of the limit frame 43 is fixed to the rotary block 42, and there is a gap between the bottom end of the limit frame 43 and the upper surface of the second clamp 22. By rotating the rotary block 42, the rotary block 42 can move up and down outside the threaded column 41, thereby adjusting the height gap between the bottom of the limit frame 43 and the second clamp 22, and limiting the upward movable stroke of the second clamp 22 to meet the need for controlling the tightness when the weft yarn is threaded.

[0049] The outer side of the rotating block 42 is provided with an anti-slip groove 44 to facilitate the hand to apply force.

[0050] It is worth noting that in the two embodiments of the tensioning mechanism 32, a support plate 12 is fixed to the bottom end of the mounting plate 1, and the mounting plate 1 is fixed to the external spinning frame through the support plate 12. For the first embodiment of the tensioning mechanism 32, an opening corresponding to the position of the mounting hole 11 is provided on the support plate 12, and the outer wall of the cylinder 321 is fixed to the support plate 12 through the opening. In the second embodiment of the tensioning mechanism 32, the bottom of the mounting plate 1 is directly fixed to the support plate 12.

[0051] Among them, the support plate 12 is provided with holes 13 for threading the weft yarns. The sizes of the holes 13 are different, and the inner diameter size can be customized according to the weft yarns of different thicknesses to meet the needs of orderly threading of the weft yarns of corresponding thicknesses, thereby improving the convenience of use.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
