Description

Wire spreader and braiding system

Technical Field

The present disclosure relates to textile processes, and in particular to a wire spreader and a braiding system.

Background

With the increasing environmental awareness of people, the possibility of carrying natural environment-friendly shopping bags (such as straw plaited, bamboo plaited, rattan plaited and the like) is increased when people go out. The shopping bag has the characteristics of light weight, no net holes and the like, so the weight, thickness and compactness of the braided wire materials are specially selected, the natural forage fiber is a main material source, the wire is defined as a grass-like wire, the wire is thicker than the yarn, the rope is much thinner, and the twist is much lower than the yarn. It should be explained that the natural grass stock thread forming is a thread forming mode between ordinary spinning and ordinary rope weaving. For ordinary spinning, the raw material is natural or chemical fiber. Natural fiber: cotton, hemp, silk, wool, etc. Wherein the fiber is a relatively flexible, thin and long material having an aspect ratio generally greater than 1000:1. typical textile fibres have diameters of several microns to tens of microns, lengths exceeding 25mm, linear densities of the order of 10 ^-5 g/mm. The yarn diameter is generally about 0.13 to 0.28mm, and the yarn made of chemical fibers is finer. The diameter of the grass-like thread is generally about 0.5-1.5 mm, and the diameter of the braided rope of the machine is generally larger than 2mm and thicker.

Because of the characteristics of the grass-like yarn, the yarn is difficult to use on the existing loom, and the yarn product mainly depends on hand knitting, and has extremely low efficiency and high cost. Therefore, a special weaving machine is needed to facilitate the opening and weaving of grass-like yarns.

Detailed Description

Fig. 1a is a schematic view of a partial structure of a wire spreader according to one embodiment of the present disclosure (a portion of a first wire deformation structure and a second wire deformation structure respectively press against a first warp and a second warp). Fig. 1b is a schematic view of a partial structure of the wire spreader device of fig. 1a in another state. Fig. 1c is a schematic view of a partial structure of the line spreader as seen from the direction B in fig. 1B. Fig. 1d is a schematic view of a partial structure of the wire spreader device of fig. 1b mated with a first warp, a second warp and a weft.

As shown in fig. 1a, 1b and 1c, a wire spreader 1 includes a plurality of first wire deforming structures 11 and a plurality of second wire deforming structures 12, wherein the first wire deforming structures 11 press against the first warp threads 21 to deform the first warp threads 21, and the second wire deforming structures 12 press against the second warp threads 22 to deform the second warp threads 22. As shown in fig. 1b and 1d, the first thread deformation structures 11 and the second thread deformation structures 12 are alternately distributed along the first direction a so that the first warp threads 21 and the second warp threads 22 are alternately distributed along the first direction a. As can be seen in fig. 3b, 3c and 3d, the first thread deformation structure 11 and the second thread deformation structure 12 cooperate to form a plurality of perforations 24 between the first warp threads 21 and the second warp threads 22. And the perforation 24 is used to pass the weft yarn 23, and the first warp yarn 21 and the second warp yarn 22 sandwich the weft yarn 23 in a state where the first warp yarn 21 and the second warp yarn 22 are tensioned. Referring to fig. 1e, the first line deformation structure 11 includes a plurality of first abutting structures 111 distributed along the second direction B, and a plurality of second abutting structures 112 distributed along the second direction B.

Fig. 3b is a schematic side view of a first line deformation structure corresponding to that shown in fig. 2 b. Fig. 3c is a schematic side view of a second line deformation structure corresponding to that shown in fig. 2 d. Fig. 3d is a schematic view of the structure when the first wire deformation structure shown in fig. 3b and the second wire deformation structure shown in fig. 3c are mated. As shown in fig. 3B, the first abutting structure 111 abuts against the first warp yarn 21 so that the portion of the first warp yarn 21 abutting against the first abutting structure 111 protrudes in the third direction C, the second abutting structure 112 abuts against the first warp yarn 21 so that the portion of the first warp yarn 21 abutting against the second abutting structure 112 protrudes in the opposite direction of the third direction C, and the first abutting structure 111 and the second abutting structure 112 are alternately distributed along the second direction B so that the first warp yarn 21 is wavy. As shown in fig. 3C, the second thread deformation structure 12 includes a plurality of third abutting structures 123 and a plurality of fourth abutting structures 124, the third abutting structures 123 are abutted against the second warp threads 22 to make the second warp threads 22 protrude along the third direction C, the fourth abutting structures 124 are abutted against the second warp threads 22 to make the second warp threads 22 protrude along the opposite direction of the third direction C, and the third abutting structures 123 and the fourth abutting structures 124 are alternately distributed along the second direction B to make the second warp threads 22 wavy. However, since the waves formed by the first warp yarn 21 and the waves formed by the second warp yarn 22 are staggered, as shown in fig. 3d, the perforations 24 can be observed when the first warp yarn 21 and the second warp yarn 22 are viewed along the first direction a.

Wherein both ends of the first warp yarn 21 are forced to be tensioned in the second direction B. The second warp yarn 22 is forced to be tensioned in the second direction B at both ends, and the third direction C is perpendicular to the second direction B.

It should be understood that the tensioning is merely indicative of an action, and the tensioned threads (threads referring to the first warp thread 21, the second warp thread 22 and the weft thread 23) do not necessarily have to be straight, but may merely be a stepwise straight-like change from the original wavy form. The first warp yarn 21 being pulled in the second direction B means that both ends of the first warp yarn 21 are respectively subjected to forces in the second direction B and in a direction opposite to the second direction B, so that the first warp yarn 21 becomes extended in the second direction B. The second warp yarn 22 being pulled in the second direction B means that both ends of the second warp yarn 22 are respectively subjected to forces in the second direction B and in a direction opposite to the second direction B, so that the second warp yarn 22 becomes extended in the second direction B. Taking the first warp yarn 21 as an example, referring to fig. 3a, it is shown that the first warp yarn 21 is subjected to a first external force N extending in the second direction B and a second external force M extending in the opposite direction of the second direction B. The projections of the application points of the first external force N and the second external force M on the cross section are located at the same point, so that the first warp yarn 21 is tensioned along the second direction B under the action of the first external force N and the second external force M only, and extends along the second direction B. Wherein the cross section is perpendicular to the second direction B. More specifically, the third direction C is vertically upward, the opposite direction of the third direction C is vertically downward, the heights of the points of the first warp yarn 21 are uniform when the first warp yarn 21 extends in the second direction B, and the heights of the points of the second warp yarn 22 are uniform when the second warp yarn 22 extends in the second direction B.

When the first abutting structure 111 abuts against the first warp yarn 21 to make the first warp yarn 21 protrude in the third direction C, and the second abutting structure 112 abuts against the first warp yarn 21 to make the first warp yarn 21 protrude in the opposite direction to the third direction C, as shown in fig. 2b, the first abutting structure 111 is located below the first warp yarn 21 to push up the first warp yarn 21 to make the portion of the first warp yarn 21 abutting against the first abutting structure 111 protrude upward, and the second abutting structure 112 is located above the first warp yarn 21 to push up the first warp yarn 21 to make the portion of the first warp yarn 21 abutting against the second abutting structure 112 protrude downward, so that the first warp yarn 21 is in a wave shape as shown in fig. 2b by the alternating arrangement of the first abutting structure 111 and the second abutting structure 112.

Specifically, as shown in fig. 4a and 4b, the first abutting structure 111 includes a first driving device 1111, a second driving device 1112, a first abutting piece 1113, and a second abutting piece 1114. The first drive 1111 drives the first abutment 1113 between a first abutment position and a first distal position, and the second drive 1112 drives the second abutment 1114 between a second abutment position and a second distal position. When the first abutment 1113 is in the first abutment position, as shown in fig. 4b and 2b, the first abutment 1113 protrudes upward, and the first abutment 1113 can press against the first warp yarn 21.

When the second abutment 1114 is in the second abutment position, as shown in fig. 2b and 4b, the second abutment 1114 protrudes upwards, the second abutment 1114 presses against the first warp thread 21. When the first abutting member 1113 is at the first abutting position and the second abutting member 1114 is at the second abutting position, as shown in fig. 4b and fig. 2b, the first abutting member 1113 and the second abutting member 1114 form a first groove 1115, the first warp 21 is located in the first groove 1115, and the first abutting member 1113 and the second abutting member 1114 are pressed against the first warp 21 so as to make the first contact portion 211 protrude toward the third direction C, wherein the first contact portion 211 is a portion of the first warp 21 abutting against the first abutting member 1113 and the second abutting member 1114. The first contact portion 211 refers more precisely to a portion where the first warp yarn 21 abuts against the first abutting structure 111 when the first abutting structure 111 abuts against the first warp yarn 21 upward.

Alternatively, as shown in fig. 5a, the second abutment structure 112 includes a third driving device 1121, a fourth driving device 1122, a third abutment 1123, and a fourth abutment 1124. The third driving device 1121 drives the third abutting piece 1123 to move between the third abutting position and the third distant position, and the fourth driving device 1122 drives the fourth abutting piece 1124 to move between the fourth abutting position and the fourth distant position. As shown in fig. 5b and fig. 2b, when the third abutting piece 1123 is at the third abutting position and the fourth abutting piece 1124 is at the fourth abutting position, the third abutting piece 1123 and the fourth abutting piece 1124 form a second groove 1125, the first warp 21 is located in the second groove 1125, and the third abutting piece 1123 and the fourth abutting piece 1124 are abutted against the first warp 21, so that the second contact portion 212 protrudes in the opposite direction of the third direction C, wherein the second contact portion 212 is a portion where the first warp 21 abuts against the third abutting piece 1123 and the fourth abutting piece 1124. Specifically, when the third abutment 1123 is in the third abutment position, as shown in fig. 5b and 2b, the third abutment 1123 protrudes downward, the third abutment 1123 pressing against the first warp yarn 21. And when the fourth abutting piece 1124 is at the fourth abutting position, the fourth abutting piece 1124 extends downwards, and the fourth abutting piece 1124 abuts against the first warp yarn 21. When the third abutting piece 1123 is at the third abutting position and the fourth abutting piece 1124 is at the fourth abutting position, the third abutting piece 1123 and the fourth abutting piece 1124 form a second groove 1125, the first warp yarn 21 is located in the second groove 1125, and the third abutting piece 1123 and the fourth abutting piece 1124 are abutted against the first warp yarn 21 so that the second contact portion 212 protrudes in the opposite direction (downward in some embodiments) of the third direction C, wherein the second contact portion 212 is a portion when the first warp yarn 21 abuts against the third abutting piece 1123 and the fourth abutting piece 1124. The second contact portion 212 refers more precisely to a portion where the first warp yarn 21 abuts against the second abutting structure 112 when the second abutting structure 112 presses down against the first warp yarn 21.

Alternatively, as shown in fig. 4c and 4d, the third abutting structure 123 includes a fifth driving device 1231, a sixth driving device 1232, a fifth abutting piece 1233, and a sixth abutting piece 1234, where the fifth driving device 1231 drives the fifth abutting piece 1233 to move between a fifth abutting position and a fifth distant position, and the sixth driving device 1232 drives the sixth abutting piece 1234 to move between the sixth abutting position and the sixth distant position. As shown in fig. 2d and fig. 4d, when the fifth abutting element 1233 is at the fifth abutting position and the sixth abutting element 1234 is at the sixth abutting position, the fifth abutting element 1233 and the sixth abutting element 1234 form a third groove 1235, the second warp thread 22 is located in the third groove 1235, and the fifth abutting element 1233 and the sixth abutting element 1234 are pressed against the second warp thread 22 so as to make the third contact portion 213 protrude in the third direction C, wherein the third contact portion 213 is a portion of the second warp thread 22 abutting against the fifth abutting element 1233 and the sixth abutting element 1234. The third contact portion 213 refers more precisely to a portion where the second warp yarn 22 abuts against the third abutting structure 123 when the third abutting structure 123 abuts against the second warp yarn 22 upward.

Alternatively, as shown in fig. 5C and 5d, the fourth abutting structure 124 includes a seventh driving device 1241, an eighth driving device 1242, a seventh abutting piece 1243 and an eighth abutting piece 1244, the seventh driving device 1241 drives the seventh abutting piece 1243 to move between a seventh abutting position and a seventh distant position, the eighth driving device 1242 drives the eighth abutting piece 1244 to move between the eighth abutting position and the eighth distant position, and when the seventh abutting piece 1243 is in the seventh abutting position and the eighth abutting piece 1244 is in the eighth abutting position, the seventh abutting piece 1243 and the eighth abutting piece 1244 form a fourth groove 1245, the second warp thread 22 is located in the fourth groove 1245 and the seventh abutting piece 1243 and the eighth abutting piece 1244 abut against the second warp thread 22 to make the fourth contact portion 214 protrude in the opposite direction of the third direction C, wherein the fourth contact portion 214 is a portion of the second warp thread 22 abutting the seventh abutting piece 1243 and the eighth abutting piece 1244. The fourth contact portion 214 more precisely refers to the portion of the second warp yarn 22 that abuts against the fourth abutment structure 124 when the fourth abutment structure 124 presses down against the second warp yarn 22.

Since both ends of the first warp yarn 21 are tensioned by the external force during the spinning process, both ends of the second warp yarn 22 are tensioned by the external force, if the first warp yarn 21 or the second warp yarn 22 is simply pressed against, both the first warp yarn 21 and the second warp yarn 22 may be tensioned by the external force, so that the first warp yarn 21 and the second warp yarn 22 are difficult to form a wave shape, and the first abutting structure 111 and the second abutting structure 112 respectively pass through the first groove 1115 and the second groove 1125 to limit the first warp yarn 21 to prevent the first warp yarn 21 from separating from the first groove 1115 or the second groove 1125, so that the first warp yarn 21 cannot form a wave shape. Similarly, the third abutting structure 123 and the fourth abutting structure 124 limit the second warp yarn 22 by respectively passing through the fourth groove 1245, so as to avoid that the second warp yarn 22 is separated from the third groove 1235 or the fourth groove 1245, and the second warp yarn 22 cannot form a wave shape.

Alternatively, as shown in fig. 1g, 2a, 4e and 5e, when the first abutting member 1113 is at the first distant position or the second abutting member 1114 is at the second distant position, the first abutting member 1113 and the second abutting member 1114 cannot form the first groove 1115, and the portion of the first warp yarn 21 located in the first groove 1115 slides down under the action of external force, so that the first abutting structure 111 no longer presses the first warp yarn 21 upwards; when the third abutting piece 1123 is at the third far-away position or the fourth abutting piece 1124 is at the fourth far-away position, the third abutting piece 1123 and the fourth abutting piece 1124 cannot cooperate to form the second groove 1125, and the portion of the first warp yarn 21 located in the second groove 1125 slides upwards under the action of external force, so that the second abutting structure 112 does not press the first warp yarn 21 downwards any more, and the first warp yarn 21 is tensioned from the wave shape shown in fig. 2b to the shape shown in fig. 2 a.

Alternatively, as shown in fig. 1g, 2c, 4f and 5f, when the fifth abutment 1233 is at the fifth distant position or the sixth abutment 1234 is at the sixth distant position, the fifth abutment 1233 and the sixth abutment 1234 cannot cooperate to form the third groove 1235, and the portion of the second warp yarn 22 located in the third groove 1235 slides down under the action of external force, so that the third abutment structure 123 no longer presses the second warp yarn 22 upwards. When the seventh abutting element 1243 is at the seventh distant position or the eighth abutting element 1244 is at the eighth distant position, the seventh abutting element 1243 and the eighth abutting element 1244 cannot cooperate to form the fourth groove 1245, and the portion of the second warp yarn 22 located in the fourth groove 1245 slides upwards under the action of the external force, so that the fourth abutting structure 124 does not press the second warp yarn 22 downwards any more, and the first warp yarn 21 is tensioned from the wave shape shown in fig. 2d to the shape shown in fig. 2 c.

It should be appreciated that the first abutment 1113 is in the first, distal position with a top having a lower height than the top of the first abutment 1113 when in the first, abutment position, such that the first abutment 1113 cannot contact the first warp yarn 21 to jack the first warp yarn 21 upwardly, and, similarly, when the second abutment 1114 is in the second, distal position, the top of the second abutment 1114 is lower than the top of the second abutment 1114 when in the second, abutment position, such that the second abutment 1114 cannot contact the first warp yarn 21 to jack the first warp yarn 21 upwardly. Meanwhile, only when the first abutting piece 1113 is at the first abutting position and the second abutting piece 1114 is at the second abutting position, the first warp thread 21 can be limited in the first groove 1115 formed by the first abutting piece 1113 and the second abutting piece 1114, so as to limit the first warp thread 21 to protrude upwards, as shown in fig. 2b, 4b and 5 b. Once the first abutment 1113 is in the first distal position or the second abutment 1114 is in the second distal position, the first contact portion 211 of the first warp yarn 21 is pulled taut by the first external force N and the second external force M such that the first warp yarn 21 extends substantially in the second direction B, see in particular fig. 2a. Similarly, when the third abutting piece 1123 is at the third distant position, the bottom of the third abutting piece 1123 is located at a position higher than the height of the bottom of the third abutting piece 1123 when the third abutting piece 1123 is at the third abutting position, and at this time, the third abutting piece 1123 cannot contact the first warp yarn 21 to bulge the first warp yarn 21 downward. When the fourth abutment 1124 is in the fourth distant position, the bottom of the fourth abutment 1124 is located at a higher level than the bottom of the fourth abutment 1124 when the fourth abutment 1124 is in the fourth abutment position, at which time the fourth abutment 1124 cannot contact the first warp yarn 21 to project the first warp yarn 21 downward. Bringing the third abutment 1123 in the third distal position or the fourth abutment 1124 in the fourth distal position causes the second contact portion 212 of the first warp yarn 21 to be tensioned by the first external force N and the second external force M such that the first warp yarn 21 extends substantially in the second direction B, see in particular fig. 2a. It should be appreciated that the first warp thread 21 can be restrained in the second groove 1125 formed by the third and fourth abutments 1123, 1124 so as to allow the second contact portion 212 to protrude downward only when the third and fourth abutments 1123, 1124 are in the third and fourth abutment positions. When the fifth abutment 1233 is in the fifth distal position, it is at a position lower than the position at which it is in the fifth abutment position, at which time the fifth abutment 1233 cannot contact the first warp yarn 21 to jack up the first warp yarn 21, and similarly, when the sixth abutment 1234 is in the sixth distal position, it is at a position lower than the position at which it is in the sixth abutment position, at which time the sixth abutment 1234 cannot contact the first warp yarn 21 to jack up the first warp yarn 21. Meanwhile, only when the fifth abutment 1233 is at the fifth abutment position and the sixth abutment 1234 is at the sixth abutment position, the first warp yarn 21 can be restrained in the third groove 1235 formed by the fifth abutment 1233 and the sixth abutment 1234 to restrain the first warp yarn 21 from protruding upward. Similarly, when the seventh abutment 1243 is in the seventh away position, the bottom thereof is located at a higher level than the bottom thereof when the seventh abutment 1243 is in the seventh abutment position, and at this time, the seventh abutment 1243 cannot contact the second warp yarn 22 to downwardly bulge the second warp yarn 22. When the eighth abutment 1244 is in the eighth distant position, the bottom of the eighth abutment 1244 is located higher than the bottom of the eighth abutment 1244 when it is in the eighth abutment position, and at this time, the eighth abutment 1244 cannot contact the second warp yarn 22 to project the second warp yarn 22 downward. Meanwhile, only when the seventh abutment 1243 is at the seventh abutment position and the eighth abutment 1244 is at the eighth abutment position, the second warp thread 22 can be restrained in the fourth groove 1245 formed by the seventh abutment 1243 and the eighth abutment 1244 to restrain the second warp thread 22 from protruding downward. Once the seventh abutment 1243 is in the seventh distal position or the eighth abutment 1244 is in the eighth distal position, the fourth abutment structure 124 cannot press down against the first warp yarn 21 any more.

The present disclosure also provides a braiding system, as shown in fig. 6, comprising a weft thread feeding device 5 and the thread spreading device 1 described above. The weft thread feeding device 5 will move along a plurality of weft threads 23 in a first direction a to pass through perforations 24 corresponding to the positions of the weft threads 23, respectively, wherein the weft threads 23 extend in the first direction a.

It is understood that the perforation 24 corresponds in position to the weft thread 23 means that the perforation 24 is located on the weft thread 23 corresponding to this perforation 24 or on an extension of the corresponding weft thread 23 such that the weft thread 23 can pass through the corresponding perforation 24 when moving in the opposite direction of the first direction a.

In order to facilitate the insertion of all the weft threads 23 together into the perforations 24 corresponding to the weft threads 23, the weft thread feeding device 5 comprises, optionally as shown in fig. 7a, a plurality of clamping members 53, the clamping members 53 being adapted to clamp the weft threads 23. The plurality of clips 53 drive the weft yarn 23 to move synchronously, and specifically, the plurality of clips 53 may be connected to each other, and the weft yarn 23 is driven to move synchronously together by the interconnected clips 53.

Specifically, as shown in fig. 8a, 8b and 8c, the grip 53 includes a grip main body 531 and a plurality of grip tabs 532, the plurality of grip main bodies 531 are connected to allow the plurality of grip 53 to be connected to each other, one end of the grip tab 532 is connected to the grip main body 531, the other ends of the plurality of grip tabs 532 are drawn close to each other to grip the weft yarn 23, and a gap exists between the plurality of grip tabs 532, so that the weft yarn 23 moves in one direction by the plurality of grip tabs 532 being engaged. Specifically, the other ends of the plurality of holding pieces 532 are brought close to each other to form a holding port 55 to hold the weft yarn 23. The width w of the clamping piece becomes gradually smaller from one end of the clamping piece 532 to the other end of the clamping piece 532, so that a gap may exist between the clamping pieces 532. In some embodiments, as can be seen from fig. 7b and fig. 8a, the clamping member 53 includes a clamping main body 531, one end of the clamping main body 531 is provided with a clamping head 54, the clamping piece 532 is disposed on the clamping head 54, one end of the clamping piece 532 is connected to the clamping head 54, and the other ends of the clamping pieces 532 are close to each other to clamp the weft yarn 23. It should be appreciated that the structure of the clamping body 531 may be adapted as appropriate, as in some embodiments the clamping tab 532 is directly connected to the clamping body 531 without the need for a separate clamping head.

For better explanation of the effect of the clamping piece 532, please refer to fig. 8b, when the weft yarn 23 moves from left to right in fig. 8b, the other end (right end in fig. 8 b) of the clamping piece 532 is dragged to move to right, and the clamping opening 55 is further enlarged, so that the resistance force is small when the yarn moves along one end (left end in the drawing) of the clamping piece 532 to the other end (right end in the drawing) of the clamping piece 532. However, when the weft yarn 23 moves along the other end (right end in the drawing) of the holding piece 532 toward one end (left end in the drawing) of the holding piece 532 (i.e., from right to left in fig. 8 b), the other end of the holding piece 53 is driven to move to the left, so that the holding opening is narrowed, and the weft yarn 23 is restricted from passing. The plurality of clamping pieces 532 cooperate to enable the weft yarn 23 to pass through the clamping piece 53 only in one direction, so that the weft yarn 23 is prevented from being pulled by stress when the clamping piece 53 moves, and the weft yarn 23 is prevented from being separated from the clamping piece 53. Specifically, the clamping main body 531 and the clamping piece 532 move in the opposite direction of the first direction a to pass the weft yarn 23 located in the clamping main body 531 through the through hole 24, and referring to fig. 8b again, it can be seen that, during the process of moving the weft yarn 23 by the plurality of clamping pieces 532, the weft yarn 23 tends to move in the first direction a to separate from the possibility of clamping by the plurality of clamping pieces 532, but the weft yarn 23 cannot separate from the clamping by the plurality of clamping pieces 532 due to the fact that the plurality of clamping pieces 532 restrict the weft yarn 23 to move relative to the clamping pieces 532 only in the opposite direction of the first direction a, so that the weft yarn 23 cannot separate from the clamping piece 53.

Also as shown in fig. 7a and 7b, in order to facilitate uniform movement of the clamping member 53, in some embodiments, the weft feeding device 5 further includes a second bracket 52, and the clamping member 53 is slidably disposed in the second bracket 52 and moves in the first direction a and the opposite direction of the first direction a with respect to the second bracket 52. Optionally, a stop structure 51 is provided on the second bracket 52 to limit the sliding range of the clamping member 53.

The wire spreader 1 further includes a first bracket 7, a plurality of first movable seats 14, a plurality of second movable seats 15, a plurality of third movable seats 16, and a plurality of fourth movable seats 17, and the first movable seats 14, the second movable seats 15, the third movable seats 16, and the fourth movable seats 17 are movable along the second direction B relative to the first bracket 7. Referring to fig. 7b and 8a, a first clamping head 71 is provided on the first support 7 to fix the weft yarn 23 on the first support 7, so that the weft yarn 23 passing through the perforation 24 can be fixed relative to the first warp yarn 21 and the second warp yarn 22, thereby facilitating subsequent knitting. After the first grip 71 grips the weft yarn 23, the grip 53 can be moved in the first direction a such that the grip 53 is separated from the weft yarn 23. Since the gripper 53 moves in the first direction a with respect to the weft yarn 23 at this time, the weft yarn 23 moves in the opposite direction to the first direction a with respect to the gripper 53, and the plurality of gripping pieces 532 do not restrict the relative movement of the weft yarn 23 and the gripper 53, so that the gripper 53 and the weft yarn 23 can be smoothly separated.

Alternatively, the weft yarn 23 is disposed in the gripping body 531 and the gripping body 531 extends in the first direction a to restrict the weft yarn 23 from extending in the first direction a. By providing a gripping body to limit that the weft thread 23 can only extend in the first direction a, the weft thread 23 is not skewed, allowing it to better pass through the perforations 24.

Specifically, as shown in fig. 1a, 1c, 1e and 1f, the first contact structures 111 are disposed on the first movable seat 14, and the first contact structures 111 located on the same first movable seat 14 are distributed along the first direction a.

Therefore, the abutting structure on the movable seat can be driven to move by moving the movable seat. As shown in fig. 9a and 9B, the first movable seat 14 is moved along the second direction B relative to the first bracket 7, so as to move the first abutting structure 111 located on the first movable seat 14 along the second direction B.

Also, in some embodiments, as can be seen in fig. 1b, 1c and 1e, the first movable seat 14 and the third movable seat 16 are lower than the first warp yarn 21, the second warp yarn 22 and the weft yarn 23, and the second movable seat 15 and the fourth movable seat 17 are higher than the first warp yarn 21, the second warp yarn 22 and the weft yarn 23.

And, as an alternative, the third abutting piece 1123 is disposed under the second movable seat 15 by the third driving device 1121, the third driving device 1121 drives the third abutting piece 1123 to move downward from the third distant position to the third abutting position, and when the third abutting piece 1123 is located at the third abutting position, the bottom of the third abutting piece 1123 is lower than the weft yarn 23, so that when the third abutting piece 1123 is moved along the second direction B, the third abutting piece 1123 can drive the weft yarn 23 located in front of the second direction B thereof to move. Similarly, the fourth abutting piece 1124 is disposed on the second movable seat 15 through the fourth driving device 1122, the fourth driving device 1122 can drive the fourth abutting piece 1124 to move downwards from the fourth distant position to the fourth abutting position, and when the fourth abutting piece 1124 is located at the fourth abutting position, the bottom of the fourth abutting piece 1124 is lower than the weft yarn 23, so that when the fourth abutting piece 1124 is moved along the second direction B, the fourth abutting piece 1124 can drive the weft yarn 23 located in front of the second direction B thereof to move.

The fifth abutting element 1233 is disposed above the third movable seat 16 by the fifth driving device 1231, the fifth driving device 1231 drives the fifth abutting element 1233 to move upwards from the fifth distant position to the fifth abutting position, and when the fifth abutting element 1233 is located at the fifth abutting position, the top of the fifth abutting element 1233 is higher than the weft yarn 23, so that the fifth abutting element 1233 can drive the weft yarn 23 located in front of the second direction B to move when the fifth abutting element 1233 is moved along the second direction B. Similarly, the sixth abutment 1234 is disposed on the third movable seat 16 by the sixth driving device 1232, the sixth driving device 1232 drives the sixth abutment 1234 to move upward from the sixth distant position to the sixth abutment position, and when the sixth abutment 1234 is located at the sixth abutment position, the top of the sixth abutment 1234 is higher than the weft yarn 23, so that the sixth abutment 1234 can drive the weft yarn 23 located before the second direction B thereof to move when the sixth abutment 1234 is moved along the second direction B.

But, as an alternative, the seventh abutment 1243 is disposed below the fourth movable seat 17 by the seventh driving device 1241, the seventh driving device 1241 drives the seventh abutment 1243 to move downward from the seventh away position to the seventh abutment position, and when the seventh abutment 1243 is located at the seventh abutment position, the bottom of the seventh abutment 1243 is lower than the weft yarn 23, so that moving the seventh abutment 1243 in the second direction B can drive the weft yarn 23 located before the second direction B thereof. Similarly, the eighth abutment 1244 is disposed on the fourth movable seat 17 by the eighth driving device 1242, the eighth driving device 1242 drives the eighth abutment 1244 to move downward from the eighth away position to the eighth abutment position, and when the eighth abutment 1244 is located at the eighth abutment position, the bottom of the eighth abutment 1244 is lower than the weft yarn 23, so that the eighth abutment 1244 can drive the weft yarn 23 located before the second direction B thereof to move when the eighth abutment 1244 is moved along the second direction B.

And when the first abutment 1113 is located at the first distant position, the top of the first abutment 1113 is lower than the weft yarn 23, so that the first abutment 1113 cannot drive the weft yarn 23 located before the second direction B to move when the first abutment 1113 moves along the second direction B. Similarly, when the second abutment 1114 is located at the second distant position, the top of the second abutment 1114 is lower than the height of the weft yarn 23, so that the second abutment 1114 cannot move the weft yarn 23 located before the second direction B when the second abutment 1114 is moved in the second direction B.

And, as an alternative, when the third abutment 1123 is located at the third distant position, the bottom of the third abutment 1123 is higher than the weft yarn 23, so that the third abutment 1123 cannot move the weft yarn 23 located before the third abutment 1123 in the second direction B. Similarly, when the fourth abutment 1124 is located at the fourth distant position, the bottom of the fourth abutment 1124 is lower than the weft yarn 23, such that the fourth abutment 1124 cannot move the weft yarn 23 located before the fourth abutment 1124 in the second direction B when the fourth abutment 1124 is moved in the second direction B.

When the fifth abutment 1233 is located at the fifth distant position, the top of the fifth abutment 1233 is lower than the weft yarn 23, such that the fifth abutment 1233 cannot drive the weft yarn 23 located before the second direction B thereof to move when the fifth abutment 1233 is moved along the second direction B. Similarly, when the sixth abutment 1234 is located at the sixth distant position, the top of the sixth abutment 1234 is lower than the weft yarn 23, so that the sixth abutment 1234 cannot move the weft yarn 23 located before the sixth abutment 1234 in the second direction B when the sixth abutment 1234 is moved in the second direction B.

But, alternatively, when the seventh abutment 1243 is located at the seventh distant position, the bottom of the seventh abutment 1243 is higher than the weft yarn 23, so that the seventh abutment 1243 cannot move the weft yarn 23 located before the seventh abutment 1243 in the second direction B when the seventh abutment 1243 is moved in the second direction B. Similarly, when the eighth abutment 1244 is located at the eighth distant position, the bottom of the eighth abutment 1244 is higher than the weft yarn 23, so that the eighth abutment 1244 cannot drive the weft yarn 23 located before the eighth abutment 1244 in the second direction B when the eighth abutment 1244 is moved in the second direction B.

Therefore, when the first abutment 1113 is at the first far-away position and the second abutment 1114 is at the second abutment position (as shown in fig. 4 e), the height of the top of the second abutment 1114 is higher than the height of the weft yarn 23, and the first movable seat 14 can be moved to enable the second abutment 1114 to move the weft yarn 23. When the first abutment 1113 is at the first abutment position and the second abutment 1114 is at the second distal position, the top of the first abutment 1113 is higher than the weft yarn 23, and the first movable seat 14 can be moved to move the weft yarn 23 by the first abutment 1113.

Similarly, when the third contact 1123 is at the third contact position and the fourth contact 1124 is at the fourth distant position (as shown in fig. 5 e), the bottom of the third contact 1123 is lower than the weft yarn 23, so that the second movable seat 15 can be moved to move the weft yarn 23 by the third contact 1123. Similarly, when the third contact 1123 is at the third distant position and the fourth contact 1124 is at the fourth contact position, the fourth contact 1124 can be moved to move the weft yarn 23 by moving the second movable seat 15.

Similarly, when the fifth abutment 1233 is at the fifth away position and the sixth abutment 1234 is at the sixth abutment position (as shown in fig. 4 f), the height of the top of the sixth abutment 1234 is higher than the height of the weft yarn 23, so the third movable base 16 can be moved to move the weft yarn 23 by the sixth abutment 1234. Similarly, when the fifth abutting element 1233 is at the fifth abutting position and the sixth abutting element 1234 is at the sixth distant position, the third movable seat 16 can be moved to move the fifth abutting element 1233 to move the weft yarn 23.

Similarly, when the seventh abutment 1243 is at the seventh abutment position and the eighth abutment 1244 is at the eighth distant position (as shown in fig. 5 f), the bottom of the seventh abutment 1243 is lower than the weft yarn 23, so that the fourth movable seat 17 can be moved to move the seventh abutment 1243 to move the weft yarn 23. Similarly, when the seventh abutment 1243 is at the seventh distant position and the eighth abutment 1244 is at the eighth abutment position, the fourth movable seat 17 can be moved to move the eighth abutment 1244 along with the weft yarn 23.

By the above scheme, the movable seat can be driven to drive the weft yarn 23 to move so as to arrange the weft yarn 23 neatly. Taking fig. 9a and fig. 5e as an example, the second movable seat 15 is provided with the third abutting piece 1123 and the fourth abutting piece 1124, at this time, the third abutting piece 1123 is at the third abutting position (low position), and the fourth abutting piece 1124 is at the fourth abutting position (high position), so when the second movable seat 15 moves along the second direction B, the third abutting piece 1123 can contact the weft yarn 23 located in front of the second direction B, and drive the weft yarn 23 to move so that the weft yarn 23 and other weft yarns 23 are aligned in order, as shown in fig. 9B. Meanwhile, the third driving device 1121 may drive the third abutting piece 1123 to move upward so that the third abutting piece 1123 cannot contact the weft yarn 23.

In some embodiments, the user first alternates the first warp yarn 21 with the second warp yarn 22 along the first direction a. And continuously applying force to the first warp yarn 21 and the second warp yarn 22 to ensure that the first warp yarn 21 and the second warp yarn 22 are tensioned and extend along the second direction B, and simultaneously, adopting the yarn stretching device 1 to form wavy yarns on the first warp yarn 21 and the second warp yarn 22 respectively, as shown in fig. 1a and 3d, and forming perforations 24 between the first warp yarn 21 and the second warp yarn 22 to allow the weft yarn 23 to pass through along the first direction a. At this time, the first abutment 1113 is in the first abutment position, the second abutment 1114 is in the second abutment position, the third abutment 1123 is in the third abutment position, the fourth abutment 1124 is in the fourth abutment position, the fifth abutment 1233 is in the fifth abutment position, the sixth abutment 1234 is in the sixth abutment position, the seventh abutment 1243 is in the seventh abutment position, and the eighth abutment 1244 is in the eighth abutment position.

Then, the gripper 53 is moved to drive the weft yarn 23 through the perforation 24 between the first warp yarn 21 and the second warp yarn 22. And the weft yarn 23 is fixed to the first bracket 7 by the first clip 71. The user may then return to the first remote position by letting the first abutment 1113 return to the first remote position or the second abutment 1114 return to the second remote position. And returning the third abutment 1123 to the third distant position or the fourth abutment 1124 to the fourth distant position, such that the first warp yarn 21 is tensioned and no longer undulates, as shown in fig. 2a, 4e and 5 e. Similarly, the user may also pull the second warp yarn 22 to be strained to form a wave shape by returning the fifth abutment 1233 to the fifth distant position or the sixth abutment 1234 to the sixth distant position, and returning the seventh abutment 1243 to the seventh distant position or the eighth abutment 1244 to the eighth distant position, as shown in fig. 2c, 4f and 5 f.

At this time, since the first abutting piece 1113 is at the first abutting position or the second abutting piece 1114 is at the second abutting position, when the first movable seat 14 is moved along the second direction B, the abutting piece at the abutting position can drive the weft yarn 23 located in front of the first movable seat to move, so that the weft yarn 23 is aligned.

The advantage of the above solution is that by having the first abutment structure 111 assume the condition shown in fig. 4e, on the one hand, the first groove 1115 confining the first warp yarn 21 can be detached, so that the first warp yarn 21 slides down, forming the shape shown in fig. 2a, without forming a wave, for the subsequent knitting. On the other hand, when the first abutting structure 111 is in the state shown in fig. 4e, the second abutting piece 1114 can contact the weft yarn 23 positioned in front of the second direction B when the first abutting structure 111 is moved along the second direction B, so that the user can move the weft yarn 23 by moving the first abutting structure 111, and the weft yarn 23 is orderly arranged. It should be understood that the second abutment structure 112, the third abutment structure 123 and the fourth abutment structure 124 can all perform the above functions except for the first abutment structure 111, which is not described in further detail in this disclosure.

In addition to the use of the wire spreader 1 described above, another wire spreader 1 may be used in some embodiments. Specifically, as shown in fig. 10 to 13, the wire spreader 1 includes a plurality of third wire deforming structures 81, a plurality of fourth wire deforming structures 82, and a plurality of pressing members 832, wherein the third wire deforming structures 81 and the pressing members 832 press against the first warp yarn 21 to deform the first warp yarn 21, the fourth wire deforming structures 82 and the pressing members 832 press against the second warp yarn 22 to deform the second warp yarn 22, the third wire deforming structures 81, the fourth wire deforming structures 82, and the pressing members 832 cooperate such that a plurality of perforations 24 are formed between the first warp yarn 21 and the second warp yarn 22, the perforations 24 are used to pass through the weft yarn 23, and the first warp yarn 21 and the second warp yarn 22 clamp the weft yarn 23 in a state in which the first warp yarn 21 and the second warp yarn 22 are tensioned.

Specifically, the first warp yarns 21 and the second warp yarns 22 are alternately distributed in a first direction a and, as shown in fig. 12, the third linear deformation structures 81 and the fourth linear deformation structures 82 are alternately distributed in the first direction a. The third thread deforming structure 81 includes a plurality of fifth abutting structures 811 distributed along the second direction B, and the fifth abutting structures 811 and the pressing member 832 press the first warp threads 21 to deform the first warp threads 21 by driving the fifth abutting structures 811 to move. The fourth wire deforming structure 82 includes a plurality of sixth abutting structures 821 distributed along the second direction B, and the sixth abutting structures 821 and the pressing piece 832 press the second warp threads 22 to deform the second warp threads 22 by driving the sixth abutting structures 821 to move.

Specifically, the wire spreader 1 includes a plurality of fifth movable seats 84 distributed along the first direction a, and a plurality of sixth movable seats 85 distributed along the first direction a, the fifth abutting structure 811 is disposed on the fifth movable seats 84, and the sixth abutting structure 821 is disposed on the sixth movable seats 85. The user presses the first warp yarn by driving the fifth abutting structure 811 to move up and down, and presses the second warp yarn 22 by driving the sixth abutting structure 821 to move up and down. Normally, as shown in fig. 10, the fifth abutting structure 811 is located above the first warp yarn 21, and the sixth abutting structure 821 is also located above the second warp yarn 22. Once the perforation 24 is needed, the fifth abutting structure 811 moves downward to abut against the first warp yarn 21, and the engaging abutting piece 832 forms the first warp yarn 21 into a wave shape, and similarly, the sixth abutting structure 821 moves downward to abut against the second warp yarn 22, and the engaging abutting piece 832 forms the second warp yarn 22 into a wave shape, as shown in fig. 11.

Optionally, a fixing bracket 831 is further included, the fixing bracket 831 extending in the second direction B. The pressing piece 832 extends along the first direction a, and the ends of the pressing piece 832 are respectively fixed to the two fixing brackets 831. Therefore, one pressing member 832 can deform the plurality of first warp threads 21 and the plurality of second warp threads 22.
