[0040] It should be noted that in this document, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0041] According to an exemplary embodiment, as Figures 1 to 5As shown, the present invention provides a needle lifting installation structure 1 for installing a plurality of needle lifters 11 on a weaving device. The needle lifting installation structure 1 includes: a plurality of needle lifters 11, an upper needle lifter bracket 12 and a lower needle lifter bracket 13, and a needle lifter limiting member 14.

[0042] First, referring to Figure 1 and Figure 5 , the specific structure of the needle lifter 11 is introduced. As shown in the figure, the needle lifter includes a head portion 111, a rod portion 112, and a heel portion 113. The head portion 111 of the needle lifter 11 is provided at one end of the rod portion 112. In some embodiments, the head portion 111 and the rod portion 112 are fixedly connected by welding. The heel portion 113 is provided on the rod portion 112. In some embodiments, one end of the heel portion 113 is fixed to the rod portion 112, and the heel portion is perpendicular to the rod portion 112. Among them, the yarn model used in production can be, for example, 3K-T300 carbon fiber.

[0043] As Figure 1 , Figure 5 and Figure 7 shown, in some embodiments, the plurality of needle lifters 11 includes a plurality of first needle lifters 11a and a plurality of second needle lifters 11b. The distance between the heel portion 113 and the head portion 111 of the first needle lifter 11a is greater than the distance between the heel portion 113 and the head portion 111 of the second needle lifter 11b. The plurality of first needle lifters 11a and the plurality of second needle lifters 11b are alternately arranged on the needle lifter limiting member 14. Taking the first needle lifter 11 on the needle lifter limiting member 14 as the first needle lifter 11a as an example, the second needle lifter 11 is the second needle lifter 11b, the third needle lifter 11 is the first needle lifter 11a, and the fourth needle lifter 11 is the second needle lifter 11b. According to the above arrangement order, a plurality of first needle lifters 11a and a plurality of second needle lifters 11b are alternately arranged on the needle lifter limiting member 14 in sequence.

[0044] In this embodiment, by setting the heel portion 113 of the first needle lifter 11a and the heel portion 113 of the second needle lifter 11b at different positions on their respective rod portions 112, it effectively ensures that the needle lifter 11 is lifted at intervals under the action of the heel portion 113 for knitting, thereby improving the knitting efficiency of the double diagonal fabric structure and ensuring a stable knitting effect.

[0045] As Figure 1 shown, the head portion 111 of the needle lifter 11 includes a needle hook 1112, a needle tongue 1111, and a tongue needle rod 1113. Among them, one end of the needle tongue 1111 is rotatably connected to the tongue needle rod 1113 to facilitate the needle hook 1112 to hook the yarn of the ±45° double diagonal fabric, and the needle tongue 1111 is used to prevent the yarn from falling off from the needle hook 1112 during the knitting process.

[0046] In order to ensure that the flat sheet of 3K-T300 carbon fiber is in an unfolded state at the ±45° double-biased fabric, and to ensure that the needle tongue 1111 is smoothly opened or closed, it is necessary to hook each ±45° double-biased yarn on the needle hook 1112 of the lifting needle 11 and put it in an unfolded state at the hooking point. Therefore, the rotation axis of the needle tongue 1111 of each lifting needle 11 is along the relative second direction ( Figure 6 The plurality of slideways 1411 disposed on the needle lifting stopper 14 are arranged along the first direction ( Figure 3 The second direction is perpendicular to the first direction and perpendicular to the extending direction of the rod portion 112.

[0047] Reference Figure 1 and Figure 6 In one embodiment, the rotation axes of the needle tongues 1111 of the multiple lifting needles 11 are parallel to each other, so that the loom 4 can uniformly control the multiple lifting needles 11. In this embodiment, the angle a between the rotation axis of the needle tongue 1111 of each lifting needle 11 and the second direction is 8 to 12°. The preferred angle of the angle is 10°. The deflection setting of the needle tongue 1111 of the lifting needle 11 enables the needle tongue 1111 to be opened or closed smoothly during the knitting process when the yarn is hooked on the needle hook 1112 for knitting, and also ensures that the yarn can always remain in an unfolded state after the yarn is hooked on the needle hook 1112.

[0048] like Figure 5 As shown, the upper needle lifting bracket 12 is provided with a plurality of upper mounting holes 121 adapted to the rod portion 112 of the needle lifting bracket 11, and the upper needle lifting bracket 12 is located above the lower needle lifting bracket 13 ( Figure 5 In the Y direction shown in the figure), the lower needle lifting bracket 13 is provided with a plurality of lower mounting holes 131 adapted to the rod portion 112 of the needle lifting 11, and the lower mounting holes 131 correspond one to one with the upper mounting holes 121. Specifically, the upper mounting holes 121 of the upper needle lifting bracket 12 correspond vertically to the lower mounting holes 131 of the lower needle lifting bracket 13, so as to stably constrain the needle lifting 11 through two points at a preset distance in the upper and lower directions, thereby improving the stability of the needle lifting 11.

[0049] In one example, if Figure 5 As shown, the specifications of the upper mounting holes 121 and the lower mounting holes 131 provided on the upper needle lifting bracket 12 and the lower needle lifting bracket 13 are both φ2.1mm, and there are 380 upper mounting holes 121 and 380 lower mounting holes 131, and the hole spacing between each adjacent two upper mounting holes 121 is 2.83mm, and the hole spacing between each adjacent two lower mounting holes 131 is 2.83mm.

[0050] Among them, Figure 1 and Figure 5 As shown, the head 111 of the lifting needle is in the vertical direction (Figure 5 is higher than the upper mounting hole 121 in the Y direction (as shown in

[0051] In one example, as shown in Figure 5 and Figure 7 when the lifting needle 11 is in the initial position, the distance between the top of the lifting needle 11 and the top of the lifting needle limiting member 14 is 40 mm. As shown in Figure 3 and Figure 4 the lifting needle limiting member 14 is provided with a plurality of sliding grooves 1411 extending in the vertical direction (the Y direction shown in Figure 3 ). In the up and down direction, the sliding groove 1411 of the lifting needle limiting member 14 is located between the upper lifting needle bracket 12 and the lower lifting needle bracket 13. In the assembled state, the rod portion 112 of the lifting needle 11 passes through the upper mounting hole 121 of the upper lifting needle bracket 12 and the lower mounting hole 131 of the lower lifting needle bracket 13 in the vertical direction (the Y direction shown in Figure 5 ), and the head portion 111 of the lifting needle 11 passes through the upper mounting hole 121. Under the action of an external force, the lifting needle 11 moves in a straight line, and the heel portion 113 of the lifting needle 11 cooperates with the sliding groove 1411 of the lifting needle limiting member 14 to ensure that the lifting needle 11 moves in a straight line relative to the sliding groove 1411 in the vertical direction.

[0052] As shown in Figure 3 and Figure 4 the plurality of sliding grooves 1411 provided on the lifting needle limiting member 14 are arranged at intervals in the first direction (the X direction shown in Figure 3 ), and a plurality of lifting needles 11 are installed in each sliding groove 1411 of the lifting needle limiting member 14 in the first direction.

[0053] As shown in Figure 3 , Figure 4 and Figure 7 the plurality of sliding grooves 1411 provided on the lifting needle limiting member 14 include an upper sliding groove portion 14111 and a lower sliding groove portion 14112. The heel portion 113 of the first lifting needle 11a cooperates with the corresponding lower sliding groove portion 14112, and the heel portion 113 of the second lifting needle 11b cooperates with the corresponding upper sliding groove portion 14111. As shown in Figure 1 and Figure 3 the sliding groove 1411 is configured such that the heel portion 113 of the first lifting needle 11a is at the lowest position of the lower sliding groove portion 14112 (the lowest position along the Y direction shown in Figure 3 ), the heel portion 113 of the second lifting needle 11b is at the lowest position of the upper sliding groove portion 14111, and the head portions 111 of the first lifting needle 11a and the second lifting needle 11b are at the same height to ensure the height consistency of the first lifting needle 11 and the second lifting needle 11 in the initial position.

[0054] As shown in Figure 3 andFigure 4 As shown, the needle lifting limiter 14 is an L-shaped plate structure, including a first plate portion 141 and a second plate portion 142. A plurality of slideways 1411 provided on the needle lifting limiter 14 are located on the first plate portion 141, and the first plate portion 141 is located on the outer sides of the upper needle lifting bracket 12 and the lower needle lifting bracket 13 ( Figure 3 The second plate portion 142 is connected to the lower edge of the second plate portion 142 and is located on the side of the first plate portion 141 away from the lower needle lifting bracket 13, that is, along the Figure 3 Extends in the opposite direction of the X direction shown in .

[0055] Among them, Figure 3 and Figure 4 As shown, a plurality of mounting structures 1412 are provided on the needle lifting limiter 14, and the needle lifting limiter 14 is mounted on the upper needle lifting bracket 12 and the lower needle lifting bracket 13 by fasteners (not shown), such as bolts.

[0056] In one example, the needle lifting limiter 14 is a 3 mm thick plate made of 304 stainless steel or aluminum, and two φ5 mm mounting structures 1412 are respectively provided on the upper and lower sides of the slideway of the needle lifting limiter 14 .

[0057] In one example, if Figure 3 As shown, the length of the second plate portion 142 (in Figure 3 The extension length in the X direction shown in the figure is 30 mm, and the second plate portion 142 forms a 90° angle with the first plate portion 141. The second plate portion 142 is used to: on the one hand, the second plate portion 142 has the function of reinforcing ribs to ensure that the slideway 1411 arranged on the first plate portion 141 remains straight; on the other hand, it can be used as a second lifting needle 11b installed on the lower slide portion 14112 for placing the yarn separation member 2 when opening the yarn (refer to Figure 15 )’s pad (detailed introduction will be given later).

[0058] Among them, the fabric width is a symmetrical structure at both ends, and it is necessary to process the lifting needles 11 symmetrically arranged on the weaving equipment. In this embodiment, according to the bending direction of the second plate portion 142, the lifting needle limiter 14 is divided into the lifting needle limiter 14 (refer to Figure 3 ) and the needle lifting stopper 14' (refer to Figure 4 ).

[0059] In one example, if Figure 3As shown, the slideway 11 is a long through-hole with a diameter of φ2.1×100 mm, and the upper slideway part 14111 and the lower slideway part 14112 are staggered up and down and there are 19 of each. In the assembled state, each long through-hole corresponds to the upper mounting hole 121 of the upper needle lifting bracket 12 and the lower mounting hole 131 of the lower needle lifting bracket 13 to limit the lateral sway of the needle lifter 11, so that the needle lifter 11 can only move in a straight line in the vertical direction.

[0060] The assembly steps of multiple needle lifters include:

[0061] Pass multiple first needle lifters 11a through the upper mounting hole 121 of the upper needle lifting bracket 12 and the lower mounting hole 131 of the lower needle lifting bracket 13 until the bottom end of the rod part 112 of the first needle lifter 11a is supported by the flat plate 16. Align the lower slideway part 14112 of the needle lifter limiting part 14 with the heel part 113 of the first needle lifter 11a so that the heel part 113 of the first needle lifter 11a is located in the lower slideway part 14112. Install the second needle lifter 11b through similar steps, and the heel part 113 of the second needle lifter 11b is located in the upper slideway part 14111 of the needle lifter limiting part 14. Make the needle lifter limiting part 14 and the upper needle lifting bracket 12 and the lower needle lifting bracket 13 form a fixed connection through fasteners.

[0062] In the first direction ( Figure 3 the X direction shown) in which multiple slideways 1411 are arranged, repeat the above steps to form a fixed connection between multiple needle lifter limiting parts 14 and the upper needle lifting bracket 12 and the lower needle lifting bracket 13. In one example, 10 needle lifter limiting parts 14 are provided on each side of the weaving device, and each needle lifter limiting part 14 is fastened and connected by 4 M5×12 hexagon socket head cap screws.

[0063] As Figure 8 shown, the needle lifter mounting structure 1 further includes a flexible yarn-fixing tube 15 sleeved on the needle lifter, and the flexible yarn-fixing tube 15 can slide between a first position and a second position along the extending direction of the rod part 112 of the needle lifter. Referring to Figure 8 the leftmost part, the state when the flexible yarn-fixing tube 15 is in the first position is shown. The free end of the needle tongue 1111 of the head 111 of the needle lifter 11 abuts against the needle bar 1113 of the latch needle, and the radially outer end point of the needle tongue 1111 is located radially outside the flexible yarn-fixing tube 15. Referring to Figure 8 the middle part, the state when the flexible yarn-fixing tube 15 is in the second position is shown. The flexible yarn-fixing tube 15 wraps the head 111 of the needle lifter, so that the needle hook 1112 of the needle lifter 11 hooks the yarn.

[0064] Among them, the flexible yarn-fixing tube 15 is used to close the needle tongue 1111 to lock the yarn end hooked on the needle hook 1112. For example, the flexible yarn-fixing tube 15 can use a heat-shrinkable tube with a specification of φ2mm, a thickness of 0.1mm, and a cutting length of 10mm. Using the heat-shrinkable tube as the flexible yarn-fixing tube 15 has the following advantages: (1) The cross-sectional shape of the heat-shrinkable tube can change with the change of the cross-sectional shape of the needle tongue 1111; (2) The cross-sectional size of the heat-shrinkable tube can be easily expanded and contracted. After the yarn end is locked at the head 111 of the lifting needle 11, the cross-sectional size of the heat-shrinkable tube interface increases with the increase of the locking cross-section, and the locking effect is good; (3) The heat-shrinkable tube material is stiff and it is easier to slide up and down; (4) The thin wall thickness of the heat-shrinkable tube is 0.1mm, making the operation light.

[0065] Among them, the operation of fixing the yarn to the lifting needle includes the following steps:

[0066] Step 1: The flexible yarn-fixing tube 15 is sleeved on the tongue needle rod 1113 from the needle head. After the flexible yarn-fixing tube 15 is installed in the lifting needle 11, an external force drives the flexible yarn-fixing tube 15 to slide up and down arbitrarily on the tongue needle rod 1113 of the lifting needle 11 (refer to Figure 8 );

[0067] Step 2: The flexible yarn-fixing tube 15 slides to the lowest position of the tongue needle rod 1113 of the lifting needle 11. The needle tongue 1111 of the lifting needle 11 can be opened by an external force (or the yarn end in the needle hook 1112), and the yarn end hooked in the needle tongue 1111 is removed (refer to Figure 9 );

[0068] Step 3: The flexible yarn-fixing tube 15 slides from the lowest position to the position of the needle hook 1112 of the lifting needle 11. The needle tongue 1111 of the lifting needle 11 is closed by the flexible yarn-fixing tube 15. When there is a yarn end in the needle hook 1112, the flexible yarn-fixing tube 15 continues to move upward to lock the yarn end hooked in the needle tongue 1111 (refer to Figure 10 );

[0069] Step 4: When the flexible yarn-fixing tube 15 is located at the lowest position of the tongue needle rod 1113 of the lifting needle 11 and the needle tongue 1111 is in the opened state, the tip of the yarn guiding gun 3 can guide the yarn to pass through the needle hook 1112 of the lifting needle (refer to Figure 11 );

[0070] Step 5: Before the tip of the yarn guiding gun 3 penetrates or passes through the needle hook 1112 of the lifting needle, the yarn guiding gun 3 is rotated 90° to change the tip from the horizontal direction of the thinness to the vertical direction (refer to Figure 12 );

[0071] Step 6: After the tip of the yarn guiding gun 3 moves out of the needle hook 1112, the yarn guiding gun 3 rotates 90° with the yarn, changing the tip from the vertical direction of the thinness to the horizontal direction, so that the tip of the yarn guiding gun 3 can lead out the yarn along the horizontal unfolding direction of the yarn width; the yarn in the needle hook 1112 also rotates 90° in the same rotation direction as the tip, so that the yarn in the needle hook 1112 can be unfolded along the width direction (refer to Figure 13 )

[0072] In the above operation steps, when picking up the yarn guiding gun 3, putting down the yarn guiding gun 3, when the tip of the yarn guiding gun 3 penetrates into the needle hook 1112 of the lifting needle and after passing through the needle hook 1112, it is necessary to trigger the fixing mechanism of the yarn guiding gun 3 so that the yarn and the yarn guiding tube of the yarn guiding gun 3 do not move relatively. When the yarn guiding gun 3 moves out of the needle hook 1112 of the lifting needle, it is necessary to release the fixing mechanism of the yarn guiding gun 3 so that the yarn and the yarn guiding tube of the yarn guiding gun 3 can move relatively to lead out the yarn from the tip of the yarn guiding gun 3.

[0073] In Step 5, the width of the tip is 4 mm, the thinness is 0.2 mm, the spacing of the lifting needles is 2.83 mm, and the thickness of the tip is greater than the spacing of the lifting needles, so that the tip can only rotate 90° and penetrate vertically through the needle hook 1112 of the lifting needle.

[0074] Among them, the yarn end fixing operation specifically includes:

[0075] In one example, the yarn end fixing operation is completed by the cooperation of the operation end A and the operation end B.

[0076] For the operation end, the yarn end farther away from it is called the distal yarn end, and the yarn end closer to it is called the proximal yarn end. Among them, the distal yarn end fixing operation of the operation end A:

[0077] (1) After the operation end A confirms that the flexible yarn fixing tube 15 is sleeved on the lifting needle to be yarn-hung, move the flexible yarn fixing tube 15 to the lowermost position of the tongue needle rod 1113, and the needle tongue 1111 is in the open state;

[0078] (2) The yarn of the operation end B is locked by the yarn guiding gun 3 and the thickness of the tip of the yarn guiding gun 3 is in the vertical situation, and the tip of the yarn guiding gun 3 penetrates through the needle hook 1112 of the lifting needle to be yarn-hung;

[0079] (3) The operation end A fixes the yarn end passed through by the yarn guiding gun 3;

[0080] (4) The operation end B releases the fixing structure of the yarn guiding gun 3, pulls out the yarn guiding gun 3 from the needle hook 1112, and rotates the yarn guiding gun 3 so that the tip thickness is in the horizontal state;

[0081] (5) The operation end A rotates the held yarn head in the same direction as the yarn guiding gun 3, lifts the flexible yarn fixing tube 15, and locks the yarn head in the needle hook 1112;

[0082] (6)The operating end B triggers the fixing structure of the yarn guiding gun 3, and guides the yarn from one side of the far end of the fabric width in the horizontal direction of the width to the near end side.

[0083] Fixing operation of the near-end yarn end at the operating end B:

[0084] (1)The operating end B holds the yarn guiding gun 3 and triggers the fixing structure. After the tip of the yarn guiding gun 3 guides the yarn from one side of the far end of the fabric width to the near end side, the fixing structure of the yarn guiding gun 3 is released;

[0085] (2)After the operating end B confirms that the flexible yarn fixing tube 15 is sleeved on the knitting needle for hanging yarn, the flexible yarn fixing tube 15 is moved to the lowest position, and the needle tongue 1111 is in the open state;

[0086] (3)When the tip of the yarn guiding gun 3 at the operating end B is in the vertical state, the fixing structure of the yarn guiding gun 3 is triggered, and the tip of the yarn guiding gun 3 is passed through the needle hook 1112 of the lifting needle that needs to hang the yarn;

[0087] (4)The operating end B releases the fixing structure of the yarn guiding gun 3 and rotates the yarn guiding gun 3, so that the sheet-shaped tip and the yarn in the needle hook 1112 are rotated from the vertical state to the horizontal state;

[0088] (5)The operating end B applies an external force to move the flexible yarn fixing tube 15 upward. After locking the yarn behind the needle tip, the yarn connected to the yarn guiding gun 3 is cut.

[0089] The above-mentioned fixing operations of the far-end yarn end and the near-end yarn end are to complete the fixing of the yarn ends on the side of the fabric width (woven equipment) close to the operating end B. The operating ends A and B exchange the operation methods, that is, the operating end A performs the operations of the previous operating end B, and the operating end B performs the operations of the previous operating end A, so as to fix the yarn ends on the side of the fabric width close to the operating end A. The above operations can be completed manually or by a machine.

[0090] An embodiment of the present invention also provides a woven equipment, as Figure 14 shown, the woven equipment includes the lifting needle mounting structure 1 and the yarn separating member 2 as described above. The fabric 5 is placed above the woven equipment (refer to Figure 2 ). The yarn separating member 2 is used to lift some of the lifting needles 11 among the multiple lifting needles 11.

[0091] As Figure 14As shown, the yarn separating member 2 includes a first elongated support surface 241. One end of the first elongated support surface 241 is provided with a needle lifting positioning ring 25, and the needle lifting positioning ring 25 is adapted to the heel portion of the needle lifter. By mating the needle lifting positioning ring 25 of the yarn separating member 2 with the heel portion 113 of the needle lifter 11, specifically, by sleeving the needle lifting positioning ring 25 on the heel portion 113 of the needle lifter 11, the yarn separating member 2 rotates by a certain angle with the heel portion 113 of the needle lifter 11 as the axis, so as to lift some of the needle lifters 11 and keep other needle lifters 11 in the initial position, and then perform the shedding and yarn separating operation on the lifted needle lifters 11.

[0092] Among them, the heel portions 113 of the needle lifters 11 have the same appearance, a large number and are arranged closely. Before the shedding and yarn separating operation, multiple needle lifters 11 are all in the initial position (the lowest position), which is easy to be confused. First, sleeve the needle marking ring on the heel portion 113 of the first needle lifter 11. In order to quickly find the first needle lifter 11 for the shedding and yarn separating operation, it is necessary to remove the needle marking ring (not shown) that completed the previous shedding and yarn separating operation and sleeve it on the heel portion 113 of the needle lifter 11 to be used. One needle marking ring can be used for each of the heel portions 113 of the first needle lifter 11a and the second needle lifter 11b.

[0093] In one example, the structure of the needle marking ring is a circular ring with an inner hole of φ2.1mm, an outer hole of φ5mm and a thickness of 2mm, and the material is red plastic or black metal with a large color contrast.

[0094] As Figure 14 shown, the yarn separating member 2 further includes a second elongated support surface 221 disposed at an angle to the first elongated support surface 241. The vertical distance between the center of the needle lifting positioning ring 25 and the second elongated support surface 221 is equal to the vertical distance between the center of the heel portion 113 of the first needle lifter 11a in the needle lifters 11 and the second plate portion 142 of the needle limiting member 14 (i.e., the length of the third strip plate 23).

[0095] As Figure 14 shown, the yarn separating member 2 further includes a frame formed by sequentially connecting a first strip plate 21, a second strip plate 22, a third strip plate 23 and a fourth strip plate 24 end to end. The second strip plate 22 is perpendicular to the extending direction of the first strip plate 21, the third strip plate 23 is perpendicular to the extending direction of the second strip plate 22, and the length of the third strip plate 23 is less than the length of the first strip plate 21.

[0096] The first elongated support surface 241 is located on the fourth strip plate 24, the needle lifting positioning ring 25 is disposed at the connection end of the fourth strip plate 24 and the third strip plate 23, and the second elongated support surface 221 is located on the second strip plate 22.

[0097] The operating steps of the needle lifter shedding and yarn separating include:

[0098] (1)Turn the fourth strip plate 24 of the yarn dividing member 2 upward, align the needle lifter positioning ring 25 of the yarn dividing member 2 with the heel portion 113 of the first needle lifter 11, and fit the needle lifter positioning ring 25 onto the heel portion 113;

[0099] (2)Place the fourth strip plate 24 of the yarn dividing member 2 below the heel portion 113 of the needle lifter 11 in the initial position, and push the entire yarn dividing member 2 inward along the extending direction of the heel portion 113 until the heel portion 113 of the needle lifter 11 contacts the first strip plate 21 of the yarn dividing member 2;

[0100] (3)Rotate about the center of the needle lifter positioning ring 25 of the yarn dividing member 2, and lift the first strip plate 21 of the yarn dividing member 2, so that the heel portion 113 in contact with the fourth strip plate 24 moves upward along the slideway 1411 of the needle lifter limiting member 14, thereby driving the needle lifter 11 to move upward until the second strip plate 22 of the yarn dividing member 2 is flush with the heel portion 113 of the first needle lifter 11a, or flush with the bending portion of the first plate portion 141 and the second plate portion 142 of the needle lifter limiting member 14;

[0101] (4)Continue to push the entire yarn dividing member 2 inward until the entire fourth strip plate 24 of the yarn dividing member 2 contacts the needle lifter limiting member 14, and press the bottommost edge of the yarn dividing member 2 on the heel portion 113 of the second needle lifter 11b, or on the upper surface of the second plate portion 142 of the needle lifter limiting member 14 as the standard.

[0102] In this embodiment, the distance between the second long support surface 221 of the yarn dividing member 2 and the needle lifter positioning ring 25 is equal to the distance between the center of the heel portion 113 of the first needle lifter 11a and the second plate portion 142 of the needle lifter limiting member 14. So that when the first long support surface 241 of the yarn dividing member 2 (rotates a preset angle about the needle lifter positioning ring 25) lifts some of the needle lifters 11 until the second long support surface 221 is horizontal with the second plate portion 142, the second plate portion 142 supports the yarn dividing member 2. Taking this as a reference, when grouping and lifting all the needle lifters 11, the first long support surface 241 can lift the same number of needle lifters, so as to avoid missing or repeatedly lifting the needle lifters 11, and improve the efficiency of shedding and yarn dividing.

[0103] In some possible embodiments, the vertical distance between the center of the needle lifter positioning ring 25 and the second long support surface 221 is equal. So that when the first long support surface 241 of the yarn dividing member 2 (rotates a preset angle about the needle lifter positioning ring) lifts some of the needle lifters 11 until the second long support surface 221 is horizontal with the heel portions 113 of multiple first needle lifters 11a, the heel portions 113 of the first needle lifters 11a support the yarn dividing member 2. Taking this as a reference, when grouping and lifting all the needle lifters 11, the first long support surface 241 can lift the same number of needle lifters 11, so as to avoid missing or repeatedly lifting the needle lifters, and improve the efficiency of shedding and yarn dividing.

[0104] The above two schemes can be set independently or exist simultaneously.

[0105] It should be noted that the distance between the needle-lifting positioning ring 25 and the second long-shaped supporting surface 221 is not limited to this. In the present invention, the distance is set to be equal to the vertical distance between the center of the heel part 113 of the first needle 11a in the needle 11 and the second plate part 142 of the needle-lifting limiting member 14, and equal to the vertical distance between the center of the heel part 113 of the first needle 11a of the needle 11 and the center of the heel part 113 of the second needle 11b, which is only one of the implementation schemes. In some possible embodiments, a horizontal protrusion can be provided on the side of the needle-lifting limiting member 14 close to the second plate part 142. Then, during the opening and yarn splitting process, the second long-shaped supporting surface 221 of the yarn splitting member 2 is placed on the horizontal protrusion. At this time, the distance between the needle-lifting positioning ring 25 and the second long-shaped supporting surface 221 becomes smaller, and the foregoing effect can also be achieved.

[0106] The specifications of the yarn splitting member 2 need to be determined according to the fabric width. It is necessary to confirm that all the needles 11 are in the starting position, and it is necessary to confirm that a needle-lifting marking ring is sleeved on the heel part 113 of the first needle 11 for which the opening and yarn splitting are to be performed.

[0107] Specifically, the yarn splitting member 2 can be designed as follows:

[0108] The length of the fourth strip plate 24 of the yarn splitting member 2 is L, the length of the second strip plate 22 is M, and M changes with the change of the fabric width F. M = 0.707(F + 50 mm), where 50 mm is the width occupied by the edge sealing and trimming. The length H of the first strip plate 21 of the yarn splitting member 2 is 100 mm, and L = , so when the fabric width changes, the yarn splitting member 2 needs to be replaced; when designing and processing a double-diagonal fabric with a width F = 1000 mm, the yarn splitting member 2 is made by welding a 3 mm × 30 mm angle iron and a 3 mm × 30 mm flat iron. M = 742 mm, H = 100 mm, L = 748 mm. The first long-shaped supporting surface 241 corresponds to several needles 264, and the second long-shaped supporting surface 221M corresponds to 262 needles. Each time an opening and yarn splitting operation is performed, the number of needles to be lifted is 131.

[0109] Among them, after completing the operations of guiding the yarn and fixing the yarn end, it is necessary to restore the lifted needles to the initial position. The operation steps include:

[0110] (1) Pull outward ( Figure 14 the direction perpendicular to X and Y shown in

[0111] (2)Use the first long support surface 241 of the yarn separating member 2 to press down the heel portion 113 of the lifting needle 11 until all the lifting needles 11 are in the starting position;

[0112] (3)Remove the lifting needle marking ring on the heel portion 113 of the first lifting needle 11 in this operation and put it on the heel portion 113 of the next lifting needle 11 ready for yarn hanging operation.

[0113] The weaving device adopts the above-mentioned yarn separating member 2 and the above-mentioned opening yarn separating step. By abutting the second long support surface 221 of the yarn separating member 2 against the second plate portion 142 of the lifting needle limiting member 14, the first lifting needle 11a is quickly opened and separated. Also, by abutting the second long support surface 221 against the heel portions 113 of multiple first lifting needles 11a, the second lifting needle 11b is lifted and quickly opened and separated. Also, by using the lifting needle marking ring to record the starting lifting needle, a quick and accurate opening and yarn separating operation for the lifting needle 11 is realized, improving the working efficiency.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
