Description

Thread spreader and knitting system

Technical Field

The present disclosure relates to textile processes, and in particular to thread distraction devices and weaving systems.

Background

With the increasing environmental awareness of people, people have a greater and greater possibility of carrying natural environment-friendly shopping bags (such as straw plaited articles, bamboo plaited articles, rattan plaited articles and the like) when going out. The shopping bag has the characteristics of light weight, no net holes and the like, so the weight, the thickness and the compactness among the wires of the braided wire material per unit length need to be specially selected, and the natural forage fiber is the main material source, so the wire is defined as a grass-like wire which is thicker than a yarn, much thinner than a rope and much lower in twist than the yarn. It should be explained that the natural grass raw material line is a line forming mode between the common spinning and the common rope weaving. For ordinary spinning, the raw material is natural or chemical fiber. Natural fibers: cotton, hemp, silk, wool, and the like. Wherein, the fiber is a flexible thin and long substance, the length-diameter ratio is generally more than 1000:1. typical textile fibers have a diameter of a few to a few tens of micrometers, a length of more than 25mm and a linear density of the order of 10 ^-5 g/mm. The diameter of the yarn is generally about 0.13-0.28 mm, and the yarn made of chemical fiber is thinner. The diameter of the grass-like wire is generally 0.5 to EThe braided rope diameter of a common machine is about 1.5mm, is generally larger than 2mm, and is thicker.

Due to the characteristics of grass-like yarns, the grass-like yarns are difficult to use on the existing weaving machine, and the wire products mainly depend on hand weaving, so that the efficiency is extremely low, and the cost is high. Therefore, a special weaving machine is needed to facilitate the stretching and weaving of the grass-like thread.

Detailed Description

Fig. 1a is a schematic partial structure view of a thread spreading device in one state according to one embodiment of the present disclosure (a portion of a first thread-deforming structure and a portion of a second thread-deforming structure respectively press against a first warp thread and a second warp thread). FIG. 1b is a partial schematic view of the wire distraction device of FIG. 1a in another state. Fig. 1c is a partial schematic view of the thread spacer shown in fig. 1B, viewed from the direction B. FIG. 1d is a partial schematic view of the thread spreading device of FIG. 1b in cooperation with the first warp threads, the second warp threads and the weft threads.

As shown in fig. 1a, fig. 1b and fig. 1c, a thread spreading device 1 includes a plurality of first thread-deforming structures 11 and a plurality of second thread-deforming structures 12, wherein the first thread-deforming structures 11 are pressed against first warps 21 to deform the first warps 21, and the second thread-deforming structures 12 are pressed against second warps 22 to deform the second warps 22. As shown in fig. 1b and fig. 1d, the first warp threads 21 and the second warp threads 22 are alternately distributed along the first direction a by the first warp threads 11 and the second warp threads 12. As can be seen from fig. 3b, 3c and 3d, the first warp threads 21 and the second warp threads 22 form a plurality of through holes 24 between the first warp threads 11 and the second warp threads 12. And the perforations 24 are used to pass the weft 23, and the first and second warp 21 and 22 sandwich the weft 23 in a state where the first and second warp 21 and 22 are tensioned. Referring to fig. 1e, the first wire deforming 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 wire modification corresponding to the first wire modification shown in fig. 2 b. Fig. 3c is a schematic side view of a second wire modification corresponding to the second wire modification shown in fig. 2 d. Fig. 3d is a schematic view of the first wire deformation structure shown in fig. 3b and the second wire deformation structure shown in fig. 3c when mated. As shown in fig. 3B, the first abutting structure 111 abuts against the first warp yarn 21 to make the portion of the first warp yarn 21 abutting against the first abutting structure 111 protrude in the third direction C, the second abutting structure 112 abuts against the first warp yarn 21 to make the portion of the first warp yarn 21 abutting against the second abutting structure 112 protrude 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 to make the first warp yarn 21 take a wavy shape. As shown in fig. 3C, the second wire deforming structure 12 includes a plurality of third abutting structures 123 and a plurality of fourth abutting structures 124, the third abutting structures 123 abut against the second warp 22 to make the second warp 22 protrude along the third direction C, the fourth abutting structures 124 abut against the second warp 22 to make the second warp 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 22 take a wavy shape. Since the undulations formed by the first warp threads 21 are staggered with respect to the undulations formed by the second warp threads 22, the perforations 24 are visible when the first warp threads 21 and the second warp threads 22 are viewed in the first direction a, as shown in fig. 3 d.

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

It should be understood that the tension is merely indicative of an action, and the tensioned threads (threads referring to the first warp threads 21, the second warp threads 22 and the weft threads 23) do not necessarily have to be straight, and may only gradually change from the original wavy shape to a state similar to a straight line. The first warp 21 is tensioned along the second direction B means that two ends of the first warp 21 are respectively subjected to a force along the second direction B and a force along the direction opposite to the second direction B, so that the first warp 21 extends along the second direction B. The second warp yarn 22 is tensioned along the second direction B means that both ends of the second warp yarn 22 are respectively subjected to forces along the second direction B and the direction opposite to the second direction B, so that the second warp yarn 22 becomes to extend along the second direction B. Taking the first warp yarn 21 as an example, referring to fig. 3a, the first warp yarn 21 is shown to be subjected to a first external force N extending in the second direction B and a second external force M extending in a direction opposite to the second direction B. And 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 only the first external force N and the second external force M to extend 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 reverse direction of the third direction C is vertically downward, and when the first longitude line 21 extends along the second direction B, the heights of the points of the first longitude line 21 are uniform, and similarly, when the second longitude line 22 extends along the second direction B, the heights of the points of the second longitude line 22 are uniform.

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 of the third direction C, as shown in fig. 2b, the first abutting structure 111 is located below the first warp yarn 21 to jack up the first warp yarn 21 upward 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 jack up the first warp yarn 21 downward to make the portion of the first warp yarn 21 abutting against the second abutting structure 112 protrude downward, and the first warp yarn 21 is finally made into 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 member 1113, and a second abutting member 1114. The first driving device 1111 drives the first contact member 1113 to move between the first contact position and the first spaced-apart position, and the second driving device 1112 drives the second contact member 1114 to move between the second contact position and the second spaced-apart position. When the first abutting member 1113 is at the first abutting position, as shown in fig. 4b and fig. 2b, the first abutting member 1113 extends upward, and the first abutting member 1113 can press the first warp thread 21.

When the second abutting member 1114 is at the second abutting position, as shown in fig. 2b and fig. 4b, the second abutting member 1114 extends upward, and the second abutting member 1114 abuts 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 yarn 21 is located in the first groove 1115, and the first abutting member 1113 and the second abutting member 1114 abut against the first warp yarn 21 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 yarn 21 abutting against the first abutting member 1113 and the second abutting member 1114. The first contact portion 211 more precisely refers to a portion where the first warp yarn 21 will abut against the first abutting structure 111 when the first abutting structure 111 abuts against the first warp yarn 21 upwards.

Alternatively, as shown in fig. 5a, the second abutting structure 112 includes a third driving device 1121, a fourth driving device 1122, a third abutting piece 1123 and a fourth abutting piece 1124. The third driving device 1121 drives the third contact member 1123 to move between the third contact position and the third spaced position, and the fourth driving device 1122 drives the fourth contact member 1124 to move between the fourth contact position and the fourth spaced 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 yarn 21 is located in the second groove 1125, and the third abutting piece 1123 and the fourth abutting piece 1124 abut against the first warp yarn 21, so that the second contact portion 212 protrudes in a direction opposite to the third direction C, wherein the second contact portion 212 is a portion where the first warp yarn 21 abuts against the third abutting piece 1123 and the fourth abutting piece 1124. Specifically, when the third abutting piece 1123 is in the third abutting position, as shown in fig. 5b and fig. 2b, the third abutting piece 1123 is extended downward, and the third abutting piece 1123 presses the first warp 21. When the fourth abutting part 1124 is at the fourth abutting position, the fourth abutting part 1124 extends downward, and the fourth abutting part 1124 presses 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 pressed against the first warp yarn 21 to make the second contact portion 212 protrude in the opposite direction (downward in some embodiments) of the third direction C, wherein the second contact portion 212 is a portion of the first warp yarn 21 abutting against the third abutting piece 1123 and the fourth abutting piece 1124. The second contact portion 212 more precisely refers to a portion where the first warp yarn 21 abuts against the second abutting structure 112 when the second abutting structure 112 downwardly abuts against the first warp yarn 21.

Alternatively, as shown in fig. 4c and 4d, the third abutment structure 123 comprises a fifth driving device 1231, a sixth driving device 1232, a fifth abutment 1233 and a sixth abutment 1234, the fifth driving device 1231 drives the fifth abutment 1233 to move between the fifth abutment position and the fifth distant position, and the sixth driving device 1232 drives the sixth abutment 1234 to move between the sixth abutment position and the sixth distant position. As shown in fig. 2d and 4d, when the fifth abutment 1233 is at the fifth abutment position and the sixth abutment 1234 is at the sixth abutment position, the fifth abutment 1233 and the sixth abutment 1234 form a third groove 1235, the second warp yarn 22 is located in the third groove 1235, and the fifth abutment 1233 and the sixth abutment 1234 are pressed against the second warp yarn 22 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 yarn 22 abutting against the fifth abutment 1233 and the sixth abutment 1234. The third contact portion 213 refers 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 member 1243 and an eighth abutting member 1244, the seventh driving device 1241 drives the seventh abutting member 1243 to move between the seventh abutting position and the seventh distant position, the eighth driving device 1242 drives the eighth abutting member 1244 to move between the eighth abutting position and the eighth distant position, when the seventh abutting member 1243 is in the seventh abutting position and the eighth abutting member 1244 is in the eighth abutting position, the seventh abutting member 1243 and the eighth abutting member 1244 form a fourth groove 1245, the second warp thread 12422 is located in the fourth groove 1245 and the seventh abutting member 1243 and the eighth abutting member 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 the abutting portion of the seventh abutting member 1243 and the eighth abutting member 1244, and the fourth contact portion 214 is the warp thread 22 abuts against the seventh abutting member 1243 and the eighth abutting member 1244. The fourth contact portion 214 more precisely refers to a portion where the second warp yarn 22 abuts against the fourth abutting structure 124 when the fourth abutting structure 124 downwardly abuts against the second warp yarn 22.

In the weaving process, two ends of the first warp 21 are tensioned by an external force, and two ends of the second warp 22 are tensioned by an external force, so that if the first warp 21 or the second warp 22 is simply pressed against, the first warp 21 and the second warp 22 may be tensioned by an external force, so that the first warp 21 and the second warp 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 21 to prevent the first warp 21 from separating from the first groove 1115 or the second groove 1125 to cause the first warp 21 not to form a wave shape. Similarly, the third abutting structure 123 and the fourth abutting structure 124 respectively limit the second warp 22 through the fourth groove 1245, so as to prevent the second warp 22 from separating from the third groove 1235 or the fourth groove 1245, which results in that the second warp 22 cannot form a wave shape.

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

Optionally, as shown in fig. 1g, fig. 2c, fig. 4f and fig. 5f, when the fifth abutting part 1233 is at the fifth distant position or the sixth abutting part 1234 is at the sixth distant position, the fifth abutting part 1233 and the sixth abutting part 1234 cannot cooperate to form the third groove 1235, and a portion of the second warp thread 22 located in the third groove 1235 slides down under an external force, so that the third abutting structure 123 does not press the second warp thread 22 upwards. When the seventh abutting piece 1243 is located at the seventh remote position or the eighth abutting piece 1244 is located at the eighth remote position, the seventh abutting piece 1243 and the eighth abutting piece 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 upward under the action of an external force, so that the fourth abutting structure 124 no longer presses the second warp yarn 22 downward, and the first warp yarn 21 is pulled tight from the wavy shape shown in fig. 2d to the shape shown in fig. 2 c.

It should be understood that the first abutting member 1113 is at the first distant position, and the height of the top thereof is lower than that of the first abutting member 1113 at the first abutting position, and at this time, the first abutting member 1113 cannot contact the first warp thread 21 to jack up the first warp thread 21, and similarly, when the second abutting member 1114 is at the second distant position, the height of the top thereof is lower than that of the second abutting member 1114 at the second abutting position, and at this time, the second abutting member 1114 cannot contact the first warp thread 21 to jack up the first warp thread 21. Meanwhile, only when the first abutting piece 1113 is in the first abutting position and the second abutting piece 1114 is in the second abutting position, the first warp thread 21 can be restricted in the first groove 1115 formed by the first abutting piece 1113 and the second abutting piece 1114 to restrict the first warp thread 21 from protruding upwards, as shown in fig. 2b, 4b and 5 b. Once the first abutting part 1113 is in the first distant position or the second abutting part 1114 is in the second distant position, the first contact part 211 of the first warp thread 21 is pulled tight by the first external force N and the second external force M, so that the first warp thread 21 extends along the second direction B, as can be seen in detail from FIG. 2a. Similarly, when the third abutting piece 1123 is at the third distant position, the bottom of the third abutting piece 1123 is 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 21 to bulge the first warp 21 downward. When the fourth abutting part 1124 is at the fourth distant position, the bottom of the fourth abutting part 1124 is higher than the bottom of the fourth abutting part 1124 at the fourth abutting position, and at this time, the fourth abutting part 1124 cannot contact the first warp yarn 21 to protrude the first warp yarn 21 downwards. Bringing the third abutment 1123 or the fourth abutment 1124 into the third distant 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, so that the first warp yarn 21 extends substantially along the second direction B, as can be seen in fig. 2a. It should be understood that the first warp yarn 21 can be confined in the second groove 1125 formed by the third and fourth abutments 1123, 1124 only when the third abutment 1123 is in the third abutment position and the fourth abutment 1124 is in the fourth abutment position, so that the second contact portion 212 protrudes downwards. When the fifth abutting member 1233 is at the fifth distant position, the position thereof is lower than the height thereof at the fifth abutting position, and at this time, the fifth abutting member 1233 cannot contact the first warp yarn 21 to jack up the first warp yarn 21, and similarly, when the sixth abutting member 1234 is at the sixth distant position, the position thereof is lower than the height thereof at the sixth abutting position, and at this time, the sixth abutting member 1234 cannot contact the first warp yarn 21 to jack up the first warp yarn 21. Meanwhile, only when the fifth abutment 1233 is in the fifth abutment position and the sixth abutment 1234 is in 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 abutting piece 1243 is at the seventh distant position, the bottom of the seventh abutting piece 1243 is higher than the bottom of the seventh abutting piece 1243 at the seventh abutting position, and at this time, the seventh abutting piece 1243 cannot contact the second warp thread 22 to bulge the second warp thread 22 downward. When the eighth abutting piece 1244 is at the eighth distant position, the bottom of the eighth abutting piece 1244 is higher than the bottom of the eighth abutting piece 1244 at the eighth abutting position, and at this time, the eighth abutting piece 1244 cannot contact the second warp yarn 22 to protrude the second warp yarn 22 downward. Meanwhile, only 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 second warp yarn 22 can be restricted in the fourth groove 1245 formed by the seventh abutting piece 1243 and the eighth abutting piece 1244 to restrict the second warp yarn 22 from protruding downward. Once the seventh abutment 1243 is in the seventh distant position or the eighth abutment 1244 is in the eighth distant position, the fourth abutment structure 124 can no longer press the first warp thread 21 downwards.

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

It is understood that the perforation 24 corresponding to the position of the weft 23 means that the perforation 24 is located on the weft 23 corresponding to this perforation 24 or on the extension of the corresponding weft 23 such that the weft 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 perforation 24 corresponding to this weft thread 23, the weft thread entry device 5 optionally comprises, as shown in fig. 7a, a plurality of gripping members 53, the gripping members 53 being adapted to grip the weft thread 23. The plurality of gripping members 53 bring the weft thread 23 in synchronous movement, and specifically, the plurality of gripping members 53 may be connected to each other, and the weft thread 23 is brought in synchronous movement together by the interconnected gripping members 53.

Specifically, as shown in fig. 8a, 8b and 8c, the clamping member 53 includes a clamping main body 531 and a plurality of clamping pieces 532, the plurality of clamping main bodies 531 are connected to connect the plurality of clamping members 53 to each other, one end of each clamping piece 532 is connected to the clamping main body 531, the other ends of the plurality of clamping pieces 532 are close to each other to clamp the weft 23, a gap exists between the plurality of clamping pieces 532, and the plurality of clamping pieces 532 cooperate to allow the weft 23 to move in one direction. Specifically, the other ends of the plurality of gripping pieces 532 are brought close to each other to form the gripping opening 55 to grip the weft thread 23. The width w of the clamping pieces becomes gradually smaller from one end of the clamping pieces 532 to the other end of the clamping pieces 532 so that a gap may exist between the clamping pieces 532. In some embodiments, as can be seen from fig. 7b and 8a, the clamping member 53 comprises a clamping main body 531, one end of the clamping main body 531 is provided with a clamping head 54, a clamping piece 532 is disposed on the clamping head 54, one end of the clamping piece 532 is connected with the clamping head 54, and the other ends of the plurality of clamping pieces 532 are close to each other to clamp the weft thread 23. It is understood that the structure of the clamping body 531 may be adjusted according to circumstances, such as the direct connection of the clamping piece 532 with the clamping body 531 in some embodiments, without a separate clamping head.

To better explain the function of the clamping piece 532, referring to fig. 8b, when the weft thread 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 enlarged, so that the resistance applied to the thread is small when the thread moves along the direction from one end (left end in the figure) of the clamping piece 532 to the other end (right end in the figure) of the clamping piece 532. However, when the weft thread 23 moves along the other end (right end in the figure) of the clamping piece 532 in the direction of one end (left end in the figure) of the clamping piece 532 (i.e. from right to left in fig. 8 b), the other end of the clamping member 53 is driven to move to the left, so that the clamping opening is narrowed, and the passage of the weft thread 23 is restricted. The plurality of clamping pieces 532 are matched to ensure that the weft thread 23 can only pass through the clamping member 53 in one direction, thereby avoiding that the weft thread 23 is possibly pulled by force when the clamping member 53 moves, so that the weft thread 23 is separated from the clamping member 53. Specifically, the clamping main body 531 and the clamping pieces 532 will move along the opposite direction of the first direction a to make the weft thread 23 located in the clamping main body 531 pass through the through hole 24, and at this time, referring to fig. 8b again, in the process that the plurality of clamping pieces 532 drive the weft thread 23 to move, the weft thread 23 will tend to move towards the first direction a to be separated from the clamping of the plurality of clamping pieces 532, but since the plurality of clamping pieces 532 limit the weft thread 23 to move relative to the clamping pieces 532 along the opposite direction of the first direction a, the weft thread 23 cannot be separated from the clamping of the plurality of clamping pieces 532, so as to ensure that the weft thread 23 is not separated from the clamping piece 53.

As also shown in fig. 7a and 7b, in order to facilitate uniform movement of the gripping member 53, in some embodiments, the weft thread feeding device 5 further comprises a second support 52, and the gripping member 53 is slidably disposed in the second support 52 and moves in a direction opposite to the first direction a and the first direction a with respect to the second support 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 expanding device 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 in the second direction B with respect to the first bracket 7. As can be seen from fig. 7b and fig. 8a, the first bracket 7 is provided with a first clamping head 71 to fix the weft 23 on the first bracket 7, so that the weft 23 passing through the perforation 24 can be fixed with respect to the first warp 21 and the second warp 22, thereby facilitating the subsequent weaving. After the first jaw 71 grips the weft 23, the gripping member 53 may be moved in the first direction a such that the gripping member 53 is separated from the weft 23. Since the clamping member 53 moves in the first direction a with respect to the weft 23 at this time, the weft 23 moves in the opposite direction of the first direction a with respect to the clamping member 53, and the plurality of clamping pieces 532 do not restrict the relative movement of the weft 23 and the clamping member 53, so that the clamping member 53 and the weft 23 can be smoothly separated.

Optionally, the weft thread 23 is provided in the clamping main body 531 and the clamping main body 531 extends along the first direction a to limit the weft thread 23 from extending along the first direction a. By providing the clamping body to restrict the weft thread 23 to extend only in the first direction a, the weft thread 23 is not deflected, allowing it to better pass through the perforation 24.

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

When the first abutting member 1113 is located at the first distant position, the top of the first abutting member 1113 is lower than the weft 23, so that the first abutting member 1113 cannot drive the weft 23 located in front of the second direction B to move when the first abutting member 1113 is moved in the second direction B. Similarly, when the second abutting member 1114 is located at the second distant position, the top of the second abutting member 1114 is lower than the weft thread 23, so that the second abutting member 1114 cannot drive the weft thread 23 located in front of the second abutting member 1114 in the second direction B to move when the second abutting member 1114 is moved in the second direction B.

Alternatively, when the third abutting member 1123 is located at the third distant position, the bottom of the third abutting member 1123 is higher than the weft thread 23, so that the third abutting member 1123 cannot bring the weft thread 23 located in front of the second direction B to move when the third abutting member 1123 is moved in the second direction B. Similarly, when the fourth abutting part 1124 is located at the fourth far position, the bottom of the fourth abutting part 1124 is lower than the weft yarn 23, so that the fourth abutting part 1124 cannot drive the weft yarn 23 located in front of the second direction B to move when the fourth abutting part 1124 is moved along the second direction B.

When the fifth abutting member 1233 is located at the fifth distant position, the top of the fifth abutting member 1233 is lower than the weft thread 23, so that the fifth abutting member 1233 cannot bring the weft thread 23 located in front of the second direction B to move when the fifth abutting member 1233 is moved along the second direction B. Similarly, when the sixth abutment member 1234 is located at the sixth distant position, the top of the sixth abutment member 1234 is lower than the weft thread 23, so that the weft thread 23 located in front of the sixth abutment member 1234 in the second direction B cannot be moved by the sixth abutment member 1234 when the sixth abutment member 1234 is moved in the second direction B.

Alternatively, when the seventh abutting member 1243 is located at the seventh far position, the bottom of the seventh abutting member 1243 is higher than the weft thread 23, so that the seventh abutting member 1243 cannot bring the weft thread 23 located in front of the second direction B to move when the seventh abutting member 1243 is moved in the second direction B. Similarly, when the eighth abutting piece 1244 is located at the eighth distant position, the bottom of the eighth abutting piece 1244 is higher than the weft thread 23, so that the eighth abutting piece 1244 cannot bring the weft thread 23 located in front of the second direction B to move when the eighth abutting piece 1244 is moved along the second direction B.

Therefore, when the first abutting member 1113 is at the first distant position and the second abutting member 1114 is at the second abutting position (as shown in fig. 4 e), the top of the second abutting member 1114 will be higher than the weft thread 23, and the weft thread 23 can be moved by the second abutting member 1114 by moving the first movable seat 14.

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

Similarly, when the fifth abutment 1233 is at the fifth distant 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 thread 23, so that the weft thread 23 can be moved by the sixth abutment 1234 by moving the third movable seat 16. Similarly, when the fifth abutment 1233 is at the fifth abutment position and the sixth abutment 1234 is at the sixth distant position, the weft thread 23 can be moved by the fifth abutment 1233 by moving the third movable seat 16.

Similarly, when the seventh abutting member 1243 is at the seventh abutting position and the eighth abutting member 1244 is at the eighth distant position (as shown in fig. 5 f), the height of the bottom of the seventh abutting member 1243 is lower than the height of the weft thread 23, so that the weft thread 23 can be moved by the seventh abutting member 1243 by moving the fourth movable seat 17. Similarly, when the seventh abutting piece 1243 is at the seventh distant position and the eighth abutting piece 1244 is at the eighth abutting position, the weft thread 23 may be moved by the eighth abutting piece 1244 by moving the fourth movable seat 17.

Through the scheme, the weft 23 can be aligned by driving the movable seat to drive the weft 23 to move. Taking fig. 9a and 5e as an example, the second movable seat 15 is provided with a third abutting piece 1123 and a fourth abutting piece 1124, in which 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 that 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 is aligned with other weft yarns 23, as shown in fig. 9B. At the same time, the third driving device 1121 may drive the third abutment 1123 to move upward so that the third abutment 1123 cannot contact the weft thread 23.

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

Then, the weft 23 is carried through the perforations 24 between the first warp 21 and the second warp 22 by moving the gripper 53. And the weft 23 is fixed to the first bracket 7 by the first clip 71. Then, the user can return the first abutment 1113 to the first distant position or the second abutment 1114 to the second distant position. And returning the third abutting piece 1123 to the third distant position or the fourth abutting piece 1124 to the fourth distant position, so that the first warp 21 is tensioned and cannot form a wave shape any more, as shown in fig. 2a, 4e and 5 e. Similarly, the user can also make the second warp thread 22 be tensioned and unable to form a wave shape by making the fifth abutting member 1233 return to the fifth distance position or the sixth abutting member 1234 return to the sixth distance position, and making the seventh abutting member 1243 return to the seventh distance position or the eighth abutting member 1244 return to the eighth distance position, as shown in fig. 2c, fig. 4f and fig. 5 f.

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

The advantage of the above solution is that by making the first abutting structure 111 assume the state shown in fig. 4e, on the one hand, the first grooves 1115 limiting the first warp threads 21 can be detached, so that the first warp threads 21 slide down to form the shape shown in fig. 2a, and no longer form wave shape, so as to facilitate the subsequent weaving. On the other hand, when the weft thread needs to be moved, the first abutting structure 111 is in the state shown in fig. 4e, and when the first abutting structure 111 is moved along the second direction B, the second abutting piece 1114 can contact the weft thread 23 located in front of the second direction B, so that the user can move the first abutting structure 111 to move the weft thread 23, and the weft thread 23 is aligned. It should be understood that the second abutting structure 112, the third abutting structure 123 and the fourth abutting structure 124 can achieve the above functions in addition to the first abutting structure 111, and the disclosure is not additionally described.

In addition to using the wire distraction device 1 described above, another wire distraction device 1 can be used in some embodiments. Specifically, as shown in fig. 10 to 13, the thread spreading device 1 includes a plurality of third thread-deformed structures 81, a plurality of fourth thread-deformed structures 82, and a plurality of pressing members 832, wherein the third thread-deformed structures 81 and the pressing members 832 press against a first warp thread 21 to deform the first warp thread 21, the fourth thread-deformed structures 82 and the pressing members 832 press against a second warp thread 22 to deform the second warp thread 22, the third thread-deformed structures 81, the fourth thread-deformed structures 82, and the pressing members 832 cooperate to form a plurality of through holes 24 between the first warp thread 21 and the second warp thread 22, the through holes 24 are used for allowing a weft thread 23 to pass through, and in a state where the first warp thread 21 and the second warp thread 22 are tensioned, the first warp thread 21 and the second warp thread 22 clamp the weft thread 23.

Specifically, the first warp threads 21 and the second warp threads 22 are alternately distributed in the first direction a and, as shown in fig. 12, the third deformed structures 81 and the fourth deformed 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 thread 21 to deform the first warp thread 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 second warp yarn 22 is deformed by driving the sixth abutting structures 821 to move so that the sixth abutting structures 821 and the pressing member 832 press the second warp yarn 22.

The user moves up and down to press the first warp thread by driving the fifth abutting structure 811 and moves up and down to press the second warp thread 22 by driving the sixth abutting structure 821. Normally, as shown in fig. 10, the fifth abutting structure 811 is above the first warp yarn 21, and the sixth abutting structure 821 is also above the second warp yarn 22. Once the through hole 24 needs to be formed, the fifth abutting structure 811 moves downward to press against the first warp yarn 21 and cooperate with the pressing element 832 to form the first warp yarn 21 into a wave shape, and similarly, the sixth abutting structure 821 moves downward to press against the second warp yarn 22 and cooperate with the pressing element 832 to form the second warp yarn 22 into a wave shape, as shown in fig. 11.

Optionally, a fixing bracket 831 is further included, and the fixing bracket 831 extends along the second direction B. The pressing element 832 extends along the first direction a and the ends of the pressing element 832 are respectively fixed to the two fixing brackets 831. Therefore, one pressing piece 832 can deform a plurality of first warp yarns 21 and second warp yarns 22. Meanwhile, the plurality of pressing elements 832 are sequentially arranged along the second direction B, so that a plurality of positions of one first warp yarn 21 or one second warp yarn 22 are deformed to cooperate with the fifth abutting structure 811 and the sixth abutting structure 821 to form a plurality of through holes 24. The whole weaving efficiency is improved. It should be understood that the shape and arrangement of the fixing bracket 831 can be varied and is not limited to the above-described structure, and the disclosure is not further limited thereto.

Compared to the wire spreading device 1 shown in fig. 1a, the wire spreading device 1 shown in fig. 10-13 has a simpler structure, does not require too many driving devices, and is less expensive to produce. And only the fifth movable seat 84 and the sixth movable seat 85 are controlled to integrally move, so that the through holes 24 can be formed between the first warps 21 and the second warps 22, and the control difficulty is simplified.

It should be understood that although normally the fifth and sixth abutment structures 811 and 821 may be moved by the driving device, in some embodiments the fifth and sixth abutment structures 811 and 821 may also be moved up and down by manual driving. The driving device can be a motor, a cylinder and other structures with the capability of driving the object to move.

The shopping bag formed by the fabrics made of the grass-like yarns obtained by the weaving system has the characteristics of natural environmental protection which cannot be realized by most common shopping bags (plastic bags, non-woven bags, sailing bags and paper bags) on the market at present, and has light and thin fabric compared with the manually made natural bags (bags) such as bamboo baskets, grass woven bags and the like on the market. And because the fabric density degree of the shopping bag is between that of a common shopping bag and that of a manual natural bag, the weaving system can completely realize automatic and mechanized production.
