Description

Technical Field

[0001] This application relates to the field of weaving machine technology, and more particularly to a weaving device and its installation tool. Background Technology

[0002] A computerized flat knitting machine is a double-needle-plate weaving device that typically includes a needle plate and a tensioning device. The needle plate is used to hold the hooks to weave the fabric, while the tensioning device is used to pull the woven fabric to ensure that the computerized flat knitting machine can stably weave the fabric.

[0003] Currently, most of the pulling devices on the market only have the function of pulling the woven fabric. However, waste yarn is usually generated in the early stage of computer flat knitting. Traditional pulling devices cannot effectively pull the waste yarn, or the pulling effect is poor and the stability is insufficient, resulting in a large amount of waste yarn generated in the early stage of computer flat knitting. This affects the working efficiency of the weaving equipment on the one hand, and increases the weaving cost on the other. Utility Model Content

[0004] This application provides a weaving device and its installation tool, which are used to improve the weaving efficiency of the weaving device and reduce the weaving cost.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a weaving device, including needle plates and a pulling device. A preset plane is defined, which is parallel to the height direction of the weaving device. Two needle plates are symmetrically arranged about the preset plane, forming a needle plate gap between adjacent needle plates. Two pulling devices are symmetrically arranged about the preset plane, forming a pulling gap between adjacent pulling devices. Each pulling device includes a yarn-pulling needle, a pulling rake, and a pulling box. The yarn-pulling needle and the pulling rake are respectively installed in the pulling box, and the yarn-pulling needle and the pulling rake have degrees of freedom of movement relative to the pulling box. These degrees of freedom include a pulling direction parallel to the height direction of the weaving device and a hooking direction perpendicular to the preset plane. The pulling device includes a yarn-pulling state and a pulling state. When the pulling device is in the yarn-pulling state, the yarn-pulling needle reciprocates between the needle plate gap and the pulling gap. When the pulling device is in the pulling state, the pulling rake reciprocates between the end of the pulling gap facing the needle plate and the end of the pulling gap away from the needle plate.

[0007] Furthermore, the yarn-drawing needle includes a yarn-drawing needle body and an extension, the extension being connected to the end of the yarn-drawing needle body facing the needle plate; a hook is formed at the end of the extension facing the pulling gap; when the pulling device is in the yarn-drawing state, the hook moves back and forth between the needle plate gap and the pulling gap.

[0008] Furthermore, the pulling device also includes a guide rod; a pulling guide groove is formed inside the pulling rake, and the guide rod extends at least partially into the pulling guide groove; a yarn pulling guide groove is formed inside the yarn pulling needle, and the guide rod extends at least partially into the yarn pulling guide groove.

[0009] Furthermore, the traction guide groove includes a first traction section and a second traction section. The second traction section is located at the end of the first traction section away from the needle plate, and the second traction section extends obliquely towards the preset plane.

[0010] Furthermore, the yarn guiding groove includes a first yarn guiding section, a second yarn guiding section, and a third yarn guiding section connected in sequence, with the first yarn guiding section and the third yarn guiding section extending obliquely towards a preset plane.

[0011] Furthermore, the pulling device includes a pulling drive component, which includes a first pushing component and a second pushing component. The first pushing component and the second pushing component are respectively connected to two pulling rakes. Under the action of the first pushing component and the second pushing component, the pulling rake moves from the end of the pulling gap away from the needle plate to the end of the pulling gap facing the needle plate, and the two pulling rakes move alternately.

[0012] Furthermore, the traction drive includes an incomplete gear and two racks, which are respectively connected to the first and second pushing members, and the incomplete gear alternately meshes with the two racks.

[0013] Furthermore, the pulling device includes a yarn pulling drive component, which includes a connector and a guide plate. The connector is mounted on the yarn pulling needle, and a guide surface is formed on the guide plate. The connector is connected to the guide surface. The guide plate has a degree of freedom of movement relative to the yarn pulling needle. Under the action of the guide surface, the yarn pulling needle moves along the height direction of the weaving equipment.

[0014] Furthermore, the connector has multiple snap-fit ​​plates, and multiple yarn-drawing needles are connected to the connector through the snap-fit ​​plates so that the multiple yarn-drawing needles move with the connector.

[0015] Furthermore, the pulling device also includes multiple springs, with one end of each spring connected to the pulling box and the other end connected to the pulling needle or pulling rake. The springs apply a spring force away from the needle plate to the pulling rake or pulling needle.

[0016] Secondly, embodiments of this application also provide an installation tool for installing the yarn-drawing needle and the yarn-drawing rake in the above-mentioned weaving equipment into the yarn-drawing box; the installation tool includes a first positioning groove and a second positioning groove; a first protrusion is formed in the first positioning groove, and the first protrusion is at least partially engaged with the yarn-drawing needle to detachably install the yarn-drawing needle in the first positioning groove; a second protrusion is formed in the second positioning groove, and the second protrusion is at least partially engaged with the yarn-drawing rake to detachably install the yarn-drawing rake in the second positioning groove.

[0017] By using a yarn-drawing device to draw waste yarn, the speed at which the yarn is woven into fabric is increased. This reduces the amount of waste yarn and lowers the cost of weaving. On the other hand, it can also improve the weaving efficiency of the weaving equipment, further reducing the cost of weaving. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Firstly, such as Figure 1 , Figure 2 and Figure 3 As shown, as one implementation, this application provides a weaving device, including: a needle plate 1 and a pulling device 3. The needle plate 1 is used to weave fabric, and the pulling device 3 is located below the needle plate 1 and is used to pull the woven fabric to ensure that the weaving device can stably weave fabric.

[0037] Specifically, define a preset plane 2 (e.g. Figure 2 (As shown by the dotted line), the preset plane 2 is parallel to the height direction of the weaving equipment, and the two needle plates 1 are symmetrically arranged about the preset plane 2, forming a needle plate gap 101 between adjacent needle plates 1.

[0038] It should be noted that a needle plate surface 102 is formed at the end of the needle plate 1 near the preset plane 2, and a needle plate gap 101 is formed between the needle plate surfaces 102 of adjacent needle plates 1.

[0039] Two pulling devices 3 are symmetrically arranged about the preset plane 2, and a pulling gap 301 is formed between adjacent pulling devices 3. The woven fabric falls into the pulling gap 301 so that the pulling device 3 can pull the fabric.

[0040] It should be noted that there is a certain gap between the end faces of the two traction devices 3 that are close to the preset plane 2, and this gap is the traction gap 301.

[0041] The pulling device 3 includes a yarn-pulling needle 302, a pulling rake 303, and a pulling box 304. The yarn-pulling needle 302 and the pulling rake 303 are respectively installed in the pulling box 304, and the yarn-pulling needle 302 and the pulling rake 303 have a degree of freedom of movement relative to the pulling box 304. The yarn-pulling needle 302 and the pulling rake 303 move relative to the pulling box 304 to hook the fabric or waste yarn, thereby facilitating the pulling of the fabric or waste yarn.

[0042] The degrees of freedom of movement of the yarn-drawing needle 302 and the pulling rake 303 include the pulling direction parallel to the height of the weaving equipment and the hooking direction perpendicular to the preset plane 2. By moving the yarn-drawing needle 302 and the pulling rake 303 along the pulling direction, it is convenient to pull the fabric or waste yarn. By moving the yarn-drawing needle 302 and the pulling rake 303 along the hooking direction, the yarn-drawing needle 302 can hook or separate from the waste yarn, or the pulling rake 303 can hook or separate from the fabric, which is convenient for pulling the fabric or waste yarn.

[0043] Depending on the working conditions of the tensioning device 3, the tensioning device 3 includes a yarn-drawing state and a tensioning state.

[0044] When the pulling device 3 is in the yarn pulling state, the yarn pulling needle 302 moves back and forth between the needle plate gap 101 and the pulling gap 301. The yarn pulling needle 302 pulls the waste yarn from the needle plate gap 101 to the pulling gap 301. By pulling the waste yarn through the yarn pulling needle 302 of the pulling device 3, the speed of yarn weaving into fabric is increased. On the one hand, the amount of waste yarn is reduced, and the weaving cost is reduced. On the other hand, the weaving efficiency of the weaving equipment is improved, and the weaving cost is further reduced.

[0045] It should be noted that waste yarn refers to yarns that cannot be woven into fabric during the initial weaving stage of the weaving equipment. These waste yarns need to be pulled by an external pulling device so that they can be woven into fabric in the future.

[0046] When the pulling device 3 is in the pulling state, the pulling rake 303 moves back and forth between the end of the pulling gap 301 facing the needle plate 1 and the end of the pulling gap 301 away from the needle plate 1. The fabric is pulled by the pulling rake 303 to ensure that the weaving equipment can stably weave the fabric.

[0047] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 2 The directions shown are front, back, left, right, up, and down. The height direction of the weaving equipment is... Figure 2 The vertical direction is shown. The direction perpendicular to the preset plane 2 is... Figure 2 The front-back direction is shown. Preset plane 2 is parallel to the up-down and left-right directions.

[0048] like Figure 3 and Figure 4As shown, in one implementation, the pull box 304 includes a box body 3041 and a pull end cap 3042. The end of the box body 3041 facing the preset plane 2 is an open structure to facilitate the installation of the yarn-pulling needle 302 and the pull rake 303 into the box body 3041. The pull end cap 3042 is installed on the end face of the box body 3041 facing the preset plane 2, and multiple through slots are formed on the pull end cap 3042 arranged in the vertical direction to facilitate the yarn-pulling needle 302 and the pull rake 303 to extend out of the pull box 304 to pull the waste yarn or fabric.

[0049] Multiple guide ribs 30411 are formed inside the box body 3041. A first guide groove 30412 and a second guide groove 30413 are formed between adjacent guide ribs 30411. The dimensions of the first guide groove 30412 and the second guide groove 30413 are different in the left-right direction. The yarn-pulling needle 302 is installed in the first guide groove 30412 and moves along the direction of the first guide groove 30412. The first guide groove 30412 guides the movement of the yarn-pulling needle 302, thereby improving the movement stability of the yarn-pulling needle 302. The pulling rake 303 is installed in the second guide groove 30413 and moves along the direction of the second guide groove 30413. The second guide groove 30413 guides the movement of the pulling rake 303, thereby improving the movement stability of the pulling rake 303.

[0050] It should be noted that the first guide groove 30412 and the second guide groove 30413 extend in the vertical direction.

[0051] like Figure 3 As shown, in one implementation, the through groove of the pull end cap 3042 includes a pull groove 30421 and a yarn pull groove 30422. Both the pull groove 30421 and the yarn pull groove 30422 extend vertically. The top height of the yarn pull groove 30422 is higher than the top height of the pull groove 30421, and the bottom height of the yarn pull groove 30422 is lower than the bottom height of the pull groove 30421. This facilitates the yarn pull needle 302 to hook the waste yarn through the yarn pull groove 30422. At the same time, it facilitates the pull rake 303 to stably pull the fabric through the pull groove 30421.

[0052] Specifically, the pulling rake 303 is adapted to the pulling groove 30421. During the movement of the pulling rake 303, it extends into the pulling gap 301 through the pulling groove 30421 to facilitate the pulling of the fabric.

[0053] The yarn-drawing needle 302 is adapted to the yarn-drawing groove 30422. During the movement of the yarn-drawing needle 302, it extends into the needle plate gap 101 through the top of the yarn-drawing groove 30422, which facilitates the hooking of waste yarn in the needle plate gap 101. As the yarn-drawing needle 302 moves downward, it pulls the waste yarn into the pulling gap 301.

[0054] like Figure 3 As shown, in one implementation, the pulling device 3 also includes a guide rod 305, which is installed inside the housing 3041 so that the guide rod 305 can be connected to the yarn pulling needle 302 and the pulling rake 303.

[0055] It should be noted that in this implementation, the guide rod 305 does not contact the guide rib 30411, so that the guide rod 305 can be connected to the yarn-drawing needle 302 and the yarn-drawing rake 303. In some other implementations, the guide rod 305 can pass through the guide rib 30411.

[0056] like Figure 3 and Figure 5 As shown, in one implementation, a yarn-drawing guide groove 3023 is formed inside the yarn-drawing needle 302, and the guide rod 305 extends at least partially into the yarn-drawing guide groove 3023. Through the cooperation between the yarn-drawing guide groove 3023 and the guide rod 305, the yarn-drawing needle 302 moves in the hooking direction, that is, the yarn-drawing needle 302 moves in the front-back direction, so as to hook or separate the yarn-drawing needle 302 from the waste yarn.

[0057] As one implementation, the yarn guiding groove 3023 includes a first yarn guiding section 30231, a second yarn guiding section 30232 and a third yarn guiding section 30233 connected from top to bottom, with the first yarn guiding section 30231 and the third yarn guiding section 30233 extending obliquely toward the preset plane 2 respectively.

[0058] When the guide rod 305 is located in the third yarn-drawing section 30233, there is a certain distance between adjacent yarn-drawing needles 302, which facilitates the movement of waste yarn between adjacent yarn-drawing needles 302. As the yarn-drawing needles 302 move downward relative to the guide rod 305, the guide rod 305 moves from the third yarn-drawing section 30233 to the second yarn-drawing section 30232, causing the yarn-drawing needles 302 to move toward the preset plane 2. The two yarn-drawing needles 302 move closer to each other, which facilitates the engagement of the yarn-drawing needles 302 with the waste yarn and facilitates the downward pulling of the waste yarn. As the yarn-drawing needles 302 continue to move downward, the guide rod 305 moves from the second yarn-drawing section 30232 to the first yarn-drawing section 30231, and the yarn-drawing needles 302 move away from the preset plane 2 until the yarn-drawing needles 302 retract into the box 3041, thereby separating the yarn-drawing needles 302 from the waste yarn.

[0059] like Figure 3 and Figure 5As shown, in one implementation, the yarn-drawing needle 302 includes a yarn-drawing needle body 3021 and an extension 3022. The extension 3022 is connected to the end of the yarn-drawing needle body 3021 facing the needle plate 1. The yarn-drawing guide groove 3023 is located inside the yarn-drawing needle body 3021. The extension 3022 facilitates the yarn-drawing needle 302 to extend into the gap 101 between the needle plates, ensuring that the yarn-drawing needle 302 can stably hook the waste yarn.

[0060] The end of the extension 3022 facing the pulling gap 301 has a hook 3025. The hook 3025 extends downward at an angle. When the yarn pulling needle 302 moves downward, the hook 3025 hooks with the waste yarn. When the yarn pulling needle 302 moves upward, the hook 3025 does not exert an upward force on the waste yarn, thus ensuring the effectiveness of the waste yarn pulling.

[0061] When the pulling device 3 is in the yarn pulling state, the hook 3025 moves back and forth between the needle plate gap 101 and the pulling gap 301. By extending the hook 3025 into the needle plate gap 101, it is convenient to hook the waste yarn and improve the stability of the pulling device 3.

[0062] As one implementation, the needle plate surface 102 is inclined relative to the preset plane 2. Along the height direction of the weaving equipment, the dimension of the needle plate gap 101 in the direction perpendicular to the preset plane 2 increases from top to bottom, so that the extension 3022 of the yarn-drawing needle 302 can extend into the needle plate gap 101, further ensuring that the yarn-drawing needle 302 can stably hook the waste yarn.

[0063] like Figure 3 and Figure 6 As shown, in one implementation, a pull guide groove 3031 is formed inside the pull rake 303, and the guide rod 305 extends at least partially into the pull guide groove 3031. Through the cooperation between the pull guide groove 3031 and the guide rod 305, the pull rake 303 moves in the hooking direction, that is, the pull rake 303 moves in the front-back direction, so as to hook or separate the pull rake 303 from the fabric.

[0064] As one implementation, the pull guide groove 3031 includes a first pull section 30311 and a second pull section 30312. The second pull section 30312 is located at the end of the first pull section 30311 away from the needle plate 1, that is, the second pull section 30312 is located below the first pull section 30311, and the second pull section 30312 extends obliquely towards the preset plane 2.

[0065] When the guide rod 305 is located within the second pulling section 30312, the pulling rake 303 is in a state of separation from the fabric. During the downward movement of the pulling rake 303 relative to the guide rod 305, the guide rod 305 moves from the second pulling section 30312 to the first pulling section 30311, and the pulling rake 303 moves toward the preset plane 2, so that the pulling rake 303 hooks with the fabric and drives the fabric to move downward.

[0066] It should be noted that when the guide rod 305 is located within the second pulling section 30312, there is a certain gap between the pulling rakes 303 located on both sides of the preset plane 2. The size of the gap is basically consistent with the size of the fabric, so as to prevent the pulling rakes 303 from driving the fabric upward and to ensure the effectiveness of the fabric pulling.

[0067] The pulling rake 303 is equipped with pulling teeth 3033, which extend downward at an angle. During the upward movement of the pulling rake 303, the pulling rake 303 can move relative to the fabric. During the downward movement of the pulling rake 303, the pulling rake 303 hooks with the fabric.

[0068] like Figure 3 , Figure 5 and Figure 6 As shown, as one implementation method, the traction device 3 also includes a limiting rod 309, which is installed inside the traction box 304.

[0069] The yarn-drawing needle 302 has a yarn-drawing limiting groove 3024 inside. The yarn-drawing limiting groove 3024 is a waist-shaped hole. The limiting rod 309 extends at least partially into the yarn-drawing limiting groove 3024. The limiting rod 309 and the yarn-drawing limiting groove 3024 work together to limit the up and down movement of the yarn-drawing needle 302, while ensuring the stability of the yarn-drawing needle 302 in drawing waste yarn.

[0070] The pulling rake 303 has a pulling limiting groove 3032 inside. The pulling limiting groove 3032 is a waist-shaped hole. The limiting rod 309 extends at least partially into the pulling limiting groove 3032. The pulling rod 309 and the pulling limiting groove 3032 work together to limit the up and down movement of the pulling rake 303, while ensuring the stability of the pulling rake 303 in pulling the fabric.

[0071] like Figure 1 and Figure 3 As shown, in one implementation, the traction device 3 includes a traction drive component 306, which includes a first pusher component 3061 and a second pusher component 3062. The first pusher component 3061 and the second pusher component 3062 are respectively connected to two traction rakes 303.

[0072] Under the action of the first pushing member 3061 and the second pushing member 3062, the pulling rake 303 moves from the end of the pulling gap 301 away from the needle plate 1 to the end of the pulling gap 301 facing the needle plate 1, that is, it is used to push the pulling rake 303 from bottom to top.

[0073] Under the action of the first pushing member 3061 and the second pushing member 3062, the two pulling rakes 303 move alternately. By moving the two pulling rakes 303 alternately, the fabric is prevented from stagnating during the upward movement of the pulling rakes 303, thereby improving the continuity of the pulling rakes 303 in pulling the fabric.

[0074] It should be noted that the first pushing member 3061 and the second pushing member 3062 are block structures, and the first pushing member 3061 and the second pushing member 3062 respectively abut against the lower end surface of the two pulling rakes 303, thereby driving the pulling rakes 303 to move upward.

[0075] As one implementation, an even number of pulling rakes 303 are installed inside the pulling box 304 so that the multiple pulling rakes 303 can be evenly divided and connected to the first pushing member 3061 and the second pushing member 3062 respectively.

[0076] It should be noted that in this implementation, four traction rakes 303 are installed inside the traction box 304, two of which are connected to the first pushing member 3061, and the other two are connected to the second pushing member 3062.

[0077] Furthermore, the pulling device 3 includes multiple pulling boxes 304, so that the fabric in different areas can be pulled by the pulling rakes 303 in different pulling boxes 304, thereby increasing the diversity of the pulling methods of the pulling device 3.

[0078] like Figure 1 , Figure 3 and Figure 7 As shown, as one implementation, the traction drive component 306 includes a motor 3065, an incomplete gear 3063, and two racks 3064. The motor 3065 is connected to the incomplete gear 3063 through a gear set and drives the incomplete gear 3063 to rotate.

[0079] Two racks 3064 are respectively connected to the first pusher 3061 and the second pusher 3062. The incomplete gear 3063 alternately meshes with the two racks 3064. That is, during the rotation of the incomplete gear 3063, the incomplete gear 3063 is connected to one of the racks 3064, driving the first pusher 3061 or the second pusher 3062 to move upward, so that the rack 3064 separated from the incomplete gear 3063 moves relative to the incomplete gear 3063, thereby facilitating the pulling rake 303 to pull the fabric.

[0080] It should be noted that the incomplete gear 3063 is fixed on the end face of one of the gears in the gear set, so that the incomplete gear 3063 can be driven to rotate by the motor 3065 and the gear set.

[0081] As one implementation, the number of motors 3065 and incomplete gears 3063 is the same as the number of pull boxes 304, and the number of racks 3064 is twice the number of pull boxes 304, thus ensuring that two racks 3064 are installed in each pull box 304.

[0082] like Figure 1 and Figure 8 As shown, in one implementation, the pulling device 3 includes a yarn pulling drive 307, which includes a connector 3071 and a guide plate 3072. The connector 3071 is mounted on the yarn pulling needle 302, and a guide surface 30721 is formed on the guide plate 3072. The connector 3071 is connected to the guide surface 30721. When the guide surface 30721 moves relative to the connector 3071, the guide surface 30721 guides the movement of the connector 3071, thereby driving the yarn pulling needle 302 to move in the up and down direction.

[0083] Specifically, the guide plate 3072 has a degree of freedom of movement relative to the yarn-drawing needle 302. During the movement of the guide plate 3072, the guide surface 30721 guides the yarn-drawing needle 302. Under the action of the guide surface 30721, the yarn-drawing needle 302 moves along the height direction of the weaving equipment.

[0084] Furthermore, under the action of the guide plate 3072, the guide surface 30721 moves in the left and right direction, and there is a certain height difference between the left and right ends of the guide surface 30721, so as to facilitate the raising and lowering of the yarn-drawing needle 302 through the guide surface 30721.

[0085] like Figure 8 As shown, in one implementation, the connector 3071 has multiple snap-fit ​​plates 30711, and multiple yarn-drawing needles 302 are connected to the connector 3071 through the snap-fit ​​plates 30711, so that the multiple yarn-drawing needles 302 move with the connector 3071, reducing the control complexity of the yarn-drawing needles 302.

[0086] As one implementation, a bearing 30712 is installed at the end of the connector 3071 facing the guide plate 3072. The connector 3071 is connected to the guide surface 30721 through the bearing 30712, which reduces the wear rate between the connector 3071 and the guide surface 30721 and improves the service life of the traction device 3.

[0087] As one implementation method, the yarn-drawing drive component 307 also includes two limiting strips 3073, both of which are parallel to the left and right directions and along the height direction of the weaving equipment. The two limiting strips 3073 are located at the upper and lower ends of the guide plate 3072, respectively.

[0088] Furthermore, the guide plate 3072 can move relative to the limiting strip 3073, so that the moving direction of the guide plate 3072 is parallel to the preset plane 2 and perpendicular to the height direction of the weaving equipment, that is, the guide plate 3072 moves in the left and right direction.

[0089] Furthermore, both limiting bars 3073 are located at the ends of the pull box 304 that are away from the preset plane 2.

[0090] It should be noted that the pulling device 3 includes two yarn pulling drive components 307, which are respectively installed on the pulling boxes 304 located on both sides of the preset plane 2.

[0091] like Figure 3 As shown, in one implementation, the pulling device 3 also includes multiple springs 308. The ends of the multiple springs 308 are respectively connected to the pulling box 304, and the other ends are respectively connected to the yarn pulling needle 302 or the pulling rake 303. The springs 308 apply a spring force away from the needle plate 1 to the pulling rake 303 or the yarn pulling needle 302. That is, under the action of the springs 308, the yarn pulling needle 302 and the pulling rake 303 move downward.

[0092] Specifically, the yarn-pulling needle 302 has a yarn-pulling hook 3026, and the spring 308 is connected to the yarn-pulling needle 302 through the yarn-pulling hook 3026. The pulling rake 303 has a pulling hook 3034, and the spring 308 is connected to the pulling rake 303 through the pulling hook 3034, thereby improving the ease of installation of the spring 308.

[0093] It should be noted that the yarn-drawing drive component 307 is used to drive the yarn-drawing needle 302 to move upward, and drives the yarn-drawing needle 302 to move downward through the spring 308; similarly, the pulling drive component 306 is used to drive the pulling rake 303 to move upward, and drives the pulling rake 303 to move downward through the spring 308.

[0094] like Figure 9 As shown, the working principle of the pulling device 3 in pulling the waste yarn is as follows:

[0095] (1.1) Under the action of the yarn-pulling drive 307 (the guide plate 3072 moves relative to the connecting member 3071), the yarn-pulling needle 302 moves to the top, and then the guide plate 3072 is reset. The guide plate 3072 separates from the yarn-pulling needle 302, and the yarn-pulling needle 302 is subjected to a downward force applied by the spring 308.

[0096] (1.2) Under the action of spring 308, the yarn-pulling needle 302 moves downward, causing the guide rod 305 to move from the third yarn-pulling section 30233 to the second yarn-pulling section 30232. The two yarn-pulling needles 302 approach each other, hook the yarn-pulling needle 302 with the waste yarn, and continuously pull the waste yarn downward.

[0097] (1.3) Under the action of spring 308, the yarn-pulling needle 302 continues to move downward, and the guide rod 305 moves from the second yarn-pulling section 30232 to the first yarn-pulling section 30231. The yarn-pulling needle 302 moves away from the preset plane 2 until the yarn-pulling needle 302 retracts into the pulling box 304, thereby separating the yarn-pulling needle 302 from the waste yarn.

[0098] (1.4) Repeat steps (1.1) to (1.3) to achieve waste yarn pulling.

[0099] It should be noted that the pulling device 3 is mainly used in the initial stage of weaving in weaving equipment to pull waste yarn.

[0100] like Figure 10 As shown, the working principle of the pulling device 3 in pulling the fabric is as follows:

[0101] (2.1) Under the action of the traction drive 306 (the rotation of the incomplete gear 3063 drives the rack 3064 to rise and fall), the traction rake 303 moves to the top. At this time, the guide rod 305 is located in the second traction section 30312, the traction rake 303 is located in the traction box 304 and is separated from the fabric. As the incomplete gear 3063 rotates, the incomplete gear 3063 separates from the rack 3064.

[0102] (2.2) Under the action of spring 308, pull rake 303 moves downward relative to guide rod 305. Guide rod 305 moves from the second pull section 30312 to the first pull section 30311. Pull rake 303 moves toward the preset plane 2, so that pull rake 303 hooks with fabric and drives fabric to move downward.

[0103] In this step, the incomplete gear 3063 sequentially drives the two racks 3064 to move upward, so that one part of the pulling rakes 303 rises under the drive of the racks 3064, while the other part of the pulling rakes 303 falls under the action of the spring 308, realizing the alternating rise and fall of multiple pulling rakes 303, thereby improving the fabric pulling efficiency.

[0104] (2.3) Repeat steps (2.1) to (2.2) to achieve fabric stretching.

[0105] It should be noted that the process of the pulling device 3 pulling the fabric occurs after the fabric has been formed.

[0106] Secondly, because the box 3041 of the pull box 304 has a certain depth, it is not convenient to manually install the yarn-pulling needle 302 and the pull rake 303 into the box 3041 in sequence, which leads to a reduction in the installation efficiency of the weaving equipment.

[0107] like Figures 11 to 15 As shown, to improve the installation efficiency of the weaving equipment, this application also provides an installation tool. The installation tool is located outside the box 3041 of the pull box 304. The installation tool is used to position and fix the yarn-drawing needle 302 and the pull rake 303 in the weaving equipment, thereby facilitating the installation of the yarn-drawing needle 302 and the pull rake 303 into the box 3041, improving the convenience of installing the yarn-drawing needle 302 and the pull rake 303 into the pull box 304, and thus improving the installation efficiency of the weaving equipment.

[0108] Specifically, the installation tool 4 includes a first positioning groove 401 and a second positioning groove 402. The first positioning groove 401 is used to fix the yarn-pulling needle 302, so as to facilitate the installation of the yarn-pulling needle 302 into the first guide groove 30412; the second positioning groove 402 is used to fix the pulling rake 303, so as to facilitate the installation of the pulling rake 303 into the second guide groove 30413.

[0109] It should be noted that the number of first positioning slots 401 in the installation tool 4 is the same as the number of first guide slots 30412, and the number of second positioning slots 402 is the same as the number of second guide slots 30413.

[0110] As one implementation method, the inner end face of the first positioning groove 401 facing away from the direction of the yarn-drawing needle 302 is basically consistent with the end face of the yarn-drawing needle 302 facing the installation tool 4, thereby positioning and installing the yarn-drawing needle 302 in the first positioning groove 401.

[0111] Similarly, the inner end face of the second positioning groove 402 facing away from the pulling rake 303 is basically consistent with the end face of the pulling rake 303 facing the installation tool 4, thereby positioning and installing the pulling rake 303 in the second positioning groove 402.

[0112] As one implementation, a first protrusion 4011 is formed in the first positioning groove 401. The first protrusion 4011 is located on the inner end face of the first positioning groove 401 away from the direction of the yarn-drawing needle 302, and the first protrusion 4011 extends toward the yarn-drawing needle 302.

[0113] When the yarn-drawing needle 302 is installed in the first positioning groove 401, the first protrusion 4011 is at least partially engaged with the yarn-drawing needle 302, so that the yarn-drawing needle 302 can be detachably installed in the first positioning groove 401.

[0114] Specifically, there is a first hooking gap between the hook tip of the yarn-drawing hook 3026 and the end face of the yarn-drawing needle 302 facing the installation tool 4. When the yarn-drawing needle 302 is installed in the first positioning groove 401, the first protrusion 4011 is at least partially inserted into the first hooking gap, thereby fixing the relative position of the yarn-drawing needle 302 and the installation tool 4 and improving the stability of the installation tool 4 in installing the yarn-drawing needle 302 into the box 3041.

[0115] As one implementation, a first locking strip 4012 is formed at the end of the first protrusion 4011 facing the yarn-drawing hook 3026. The first locking strip 4012 engages the first protrusion 4011 with the inner wall of the yarn-drawing hook 3026, thereby fixing the yarn-drawing needle 302 on the installation tool 4, which facilitates the installation of the yarn-drawing needle 302 to the box 3041 by the installation tool 4.

[0116] It should be noted that under the action of external force, the first snap-fit ​​strip 4012 can be separated from the yarn-pulling hook 3026. In this implementation, the first protrusion 4011 is only used to fix the yarn-pulling needle 302 on the installation tool 4. After the yarn-pulling needle 302 is installed, external force can be applied to the yarn-pulling needle 302 to separate the installation tool 4 from the yarn-pulling needle 302, so that the yarn-pulling needle 302 is installed in the box 3041.

[0117] As one implementation, a second protrusion 4021 is formed in the second positioning groove 402. The second protrusion 4021 is located on the inner end face of the second positioning groove 402 away from the pulling rake 303, and the second protrusion 4021 extends toward the pulling rake 303.

[0118] When the pull rake 303 is installed in the second positioning groove 402, the second protrusion 4021 is at least partially engaged with the pull rake 303 to detachably install the pull rake 303 in the second positioning groove 402.

[0119] Specifically, there is a second hooking gap between the hook tip of the pulling hook 3034 and the end face of the pulling rake 303 facing the installation tool 4. When the pulling rake 303 is installed in the second positioning groove 402, the second protrusion 4021 is at least partially inserted into the second hooking gap, thereby fixing the relative position of the pulling rake 303 and the installation tool 4 and improving the stability of the installation tool 4 in installing the pulling rake 303 into the box 3041.

[0120] As one implementation, a second snap-fit ​​strip 4022 is formed at the end of the second protrusion 4021 facing the pull hook 3034. The second snap-fit ​​strip 4022 snaps the second protrusion 4021 into the inner wall of the pull hook 3034, thereby fixing the pull rake 303 onto the installation tool 4, which facilitates the installation of the pull rake 303 onto the box 3041 by the installation tool 4.

[0121] It should be noted that under the action of external force, the second snap-fit ​​strip 4022 can be separated from the pull hook 3034. In this implementation, the second protrusion 4021 is only used to snap the pull rake 303 onto the installation tool 4. After the pull rake 303 is installed, external force can be applied to the pull rake 303 to separate the installation tool 4 from the pull rake 303, so that the pull rake 303 is installed in the box 3041.

Various modifications and variations can be made to this application by those skilled in the art.

[0123] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
