Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textiles, in particular to a pile warp height forming mechanism of a flat weaving double-arrow loom. Background Art
[0002] At present, there are two types of industrial fabric weaving at home and abroad: warp knitted space fabric and plain woven space fabric. The two types of space fabrics have different focuses and advantages. This article will focus on the texture formed by the pile warp height of plain woven space fabric.
[0003] The pile warp height of an ordinary flat-weaving double-arbor loom is formed by winding it on a fixed height plate to form a specific height. This method works well when weaving low-height mesh cloth, but once a relatively high mesh cloth is woven, it is very easy for the pile warp in the middle of the mesh cloth to be entangled, which will cause irreversible consequences when the finished product is made after subsequent coating. To improve on the traditional method, we use a push needle for horizontal pushing to send the wire to the middle of the two layers of cloth to avoid entanglement and knotting.
[0004] Based on this, a pile warp height forming mechanism for a flat weaving double-arrow loom is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
[0005] The purpose of the utility model is to provide a pile warp height forming mechanism for a flat weaving double-arrow loom, so as to solve the problem that the pile warp height of an ordinary flat weaving double-arrow loom is formed by winding on a fixed height plate to form a specific height. This method is effective when weaving a low-height mesh cloth, but once a relatively high-height mesh cloth is woven, it is very easy for the pile warp in the middle of the mesh cloth to be entangled, resulting in irreversible consequences when the finished product is made after subsequent coating.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A pile warp height forming mechanism of a flat weaving double-arrow loom comprises a crossbeam, a plurality of height-changing plates are arranged on one side of the crossbeam, a movable height-fixing plate is arranged at the outer end of the height-changing plate, a push needle is arranged inside the height-changing plate and penetrates the movable height-fixing plate, a hook is arranged on the outer side of the movable height-fixing plate, and a curved steel reed is sleeved on the height-changing plate at one side of the movable height-fixing plate.
[0008] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:
[0009] In an optional solution: the thickness of the height-variable plate and the moving height-fixing plate is 0.1 mm, and the width is 5 cm.
[0010] In an optional solution: the thickness of the push pin is 0.1 mm.
[0011] In an optional solution, the width of the push pin is consistent with the width of the perforations in the height-variable plate and the motion-fixed-height plate.
[0012] In an optional solution: the middle part of the curved reed is curved.
[0013] In an optional solution: the height-variable plate and the movable height-fixing plate are fixed parts, and the push pin is a movable part.
[0014] In an optional solution, the distance between two adjacent height-varying plates is equal.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 2. When changing the height specifications of the plain woven space cloth, it is relatively simple to adjust the machine. Just control the forward movement of the stepper motor without complicated machine modifications.
[0018] 3. It has strong variability. It has the advantage of convenient adjustment of pile warp height. It can develop some new products such as variable height plain woven space cloth.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] In one embodiment, Figure 1-Figure 3As shown, a pile warp height forming mechanism of a flat weaving double-arrow loom comprises a crossbeam 1, a plurality of variable height plates 2 are arranged on one side of the crossbeam 1, a movable height-fixing plate 6 is arranged at the outer end of the variable height plate 2, a push needle 3 is arranged inside the variable height plate 2 and penetrates the movable height-fixing plate 6, a hook 4 is arranged on the outer side of the movable height-fixing plate 6, a curved steel reed 5 is sleeved on one side of the movable height-fixing plate 6 on the variable height plate 2, the hook 4 is used to mount the pile warp, the pile warp can be hung and pushed forward, the push needle 3 is controlled by a stepper motor outside the machine, and performs horizontal reciprocating motion, and the hook 4 will hang the pile warp and send it forward during movement, changing the traditional mode of winding the variable height plate 2 to form the pile warp height, and innovatively using the push method can effectively solve the problems of wire drawing winding and knotting, and adjusting the machine is relatively simple, and the forward amount of the stepper motor can be controlled without complicated machine modifications.
[0025] In one embodiment, Figure 1 and Figure 2 As shown, the thickness of the height-changing plate 2 and the movable height-fixing plate 6 is 0.1 mm, and the width is 5 cm. The height-changing plate 2 and the movable height-fixing plate 6 that are too thick cannot pass through the curved reed 5.
[0026] In one embodiment, Figure 1 and Figure 2 As shown, the thickness of the push pin 3 is 0.1 mm, and the push pin 3 needs to cooperate with the height-changing plate 2 to pass through the curved steel reed 5, otherwise increasing the distance between the steel reeds will cause the upper and lower layers of plain woven fabric to be unable to be formed.
[0027] In one embodiment, Figure 1 and Figure 3 As shown, the width of the push pin 3 is consistent with the width of the perforations in the height-variable plate 2 and the moving height-fixing plate 6, which facilitates forward and backward horizontal pushing movement.
[0028] In one embodiment, Figure 1 and Figure 3 As shown, the middle part of the curved steel reed 5 is curved, and the curved part is designed to avoid the push needle 3. The curved steel reed 5 hits with great force, and the bending angle should not be too large. Too large a bending angle will affect the overall force. It can ensure that the operation of the push needle 3 is not interfered with while ensuring the normal weaving of the upper and lower layers of cloth.
[0029] In one embodiment, Figure 2 As shown, the height-changing plate 2 and the moving height-fixing plate 6 are fixed parts, and the push pin 3 is a movable part, which prevents interference with the push pin 3 from moving inside the height-changing plate 2.
[0030] In one embodiment, Figure 2 As shown, the distances between two adjacent height-changing plates 2 are equal, and the height-changing plates 2 are sequentially arranged at corresponding positions of the crossbeam 1 for ease of processing.
[0031] The above embodiment discloses a pile warp height forming mechanism of a flat weaving double-arrow loom. The mesh cloth is usually defined by the warp and weft density within one inch and the pile warp height. Generally speaking, the pile warp involved in weaving is called five-seven wefts, and five wefts are woven following the cloth surface, and seven wefts are left empty to form the pile warp height. Therefore, when the push needle 3 pushes horizontally for one cycle, the bent steel reed 5 makes at least 12 reciprocating motions. The function of the bent steel reed 5 is to shape the flat weaving cloth on the upper and lower surfaces. The height-changing piece 2 is fixed on the loom beam 1, and the push needle 3 is controlled by a stepper motor outside the machine to perform horizontal reciprocating motion. During the movement, the hook 4 will hook the pile warp and send it forward. After it is sent to the specified distance, it stops and waits for the pile warp to be fixed after following the weft weaving of the cloth surface before a new cycle is performed. This can effectively solve the problems of wire drawing, winding and knotting. It is relatively simple to adjust the machine by controlling the forward amount of the stepper motor without the need for tedious machine modifications.
[0032] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
