Abstract
Description
Technical Field
[0001] This application relates to the field of collar knitting machine technology, and more specifically to needle plate and collar knitting machine. Background Technology
[0002] The collar loom is a commonly used machine in the textile industry, and the needle plate is the most important component of the collar loom. Existing needle plates are usually made directly from a single flat profile through multiple cutting processes, including a certain number of needle grooves and teeth, and finally undergo heat treatment and surface treatment.
[0003] To facilitate the machining and forming of the integrated needle plate, its hardness is generally no greater than HB200. This results in the sidewalls of the needle groove or the toothed plate being prone to wear or plastic deformation during use, thus affecting the service life of the needle plate.
[0004] Therefore, how to improve the service life of the needle plate while facilitating its molding remains a pressing technical problem in this field. Summary of the Invention
[0005] In view of this, in order to solve the above-mentioned technical problems, this application provides a needle plate and a collar knitting machine.
[0006] To achieve the above objectives, one of the technical solutions adopted in this application is to provide a needle plate, which includes:
[0007] The substrate has multiple vertically extending and horizontally arranged strip grooves;
[0008] Inserts are embedded in the strip grooves, and the space between two adjacent inserts forms a pin groove;
[0009] And the toothed plate, the part of the insert located near the top of the substrate in the strip groove and the strip groove together form an insertion groove, and the toothed plate is detachably embedded in the insertion groove;
[0010] The toothed plate has partitions on its left and right sides, which are detachably embedded in the insertion slots. The hardness of the toothed plate, the partitions, and the insertion plates is higher than that of the substrate.
[0011] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a collar knitting machine, which includes a collar knitting machine body, a front needle plate and a rear needle plate; the front needle plate and the rear needle plate are disposed on the collar knitting machine body, and both the front needle plate and the rear needle plate are the aforementioned needle plates;
[0012] The front needle plate and the rear needle plate are distributed along the front-to-back direction, and the top of the front needle plate and the top of the rear needle plate are set facing each other so that the front needle plate and the rear needle plate are set at an angle to each other; a gap is formed between the top of the front needle plate and the top of the rear needle plate for the fabric to pass through.
[0013] Beneficial Effects: Unlike existing technologies, in this application, firstly, the needle groove is formed by the space between two adjacent inserts, and the inserts, toothed plates, and spacers are all detachably connected to the substrate. Thus, when any one or more of the inserts, toothed plates, and spacers wear or undergo plastic deformation, only the corresponding worn or deformed insert, toothed plate, or spacer needs to be removed and replaced with a new one, without needing to replace the entire needle plate, thereby extending the needle plate's service life. Secondly, since the hardness of the toothed plate material, the spacer material, and the insert material are all higher than the hardness of the substrate material, this not only facilitates the processing and molding of the substrate but also further improves the resistance of the toothed plates, spacers, and inserts to plastic deformation, thereby increasing the needle plate's service life. Thirdly, since the substrate is easy to process and mold, and the substrate, inserts, spacers, and toothed plates can be assembled to form the needle plate, this facilitates the forming of the needle plate. In summary, this application can improve the service life of the needle plate while facilitating its molding. Attached Figure Description

Detailed Implementation
[0026] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Combination Figure 6 See Figures 1-5 The pin plate 100 of this application includes a substrate 110, an insert 120, and a toothed plate 130.
[0028] The substrate 110 is provided with a plurality of vertically extending and horizontally arranged strip grooves 111. Inserts 120 are embedded in the strip grooves 111, and the space between two adjacent inserts 120 forms a pin groove 115. The portion of the insert 120 located near the top of the substrate 110 in the strip groove 111 forms an insertion groove 112 with the strip groove 111, and the toothed plate 130 is detachably embedded in the insertion groove 112.
[0029] The toothed plate 130 has spacers 140 on its left and right sides, and the spacers 140 are detachably embedded in the insertion slot 112. The hardness of the materials of the toothed plate 130, the spacers 140, and the insertion plate 120 is higher than that of the substrate 110.
[0030] In the above manner, firstly, the needle groove 115 is formed by the space between two adjacent inserts 120, and the inserts 120, the toothed plates 130, and the spacers 140 are all detachably connected to the substrate 110. Thus, when any one or more of the inserts 120, the toothed plates 130, and the spacers 140 wear or undergo plastic deformation, only one or more of the corresponding worn or deformed inserts 120, toothed plates 130, and spacers 140 need to be removed and replaced with new ones, without needing to replace the entire needle plate 100, thereby extending the service life of the needle plate 100. Secondly, the hardness of the materials of the toothed plates 130, the spacers 140, and the inserts 120 is higher than the hardness of the substrate 110. This not only facilitates the processing and molding of the substrate 110, but also further improves the resistance of the toothed plate 130, spacer 140, and insert plate 120 to plastic deformation, thereby increasing the service life of the needle plate 100. Thirdly, since the substrate 110 is easy to process and mold, and the substrate 110, insert plate 120, spacer 140, and toothed plate 130 can be assembled to form the needle plate 100, this facilitates the molding of the needle plate 100. In summary, this application can improve the service life of the needle plate 100 while facilitating its molding.
[0031] For example, and not as a limitation, the insert 120 is detachably embedded in the slot 111 and fixed to the substrate 110 by riveting (not shown). Thus, when the riveting is present, a stable connection can be formed between the insert 120 and the substrate 110. When the riveting is removed by a tool, the insert 120 can be detached from the substrate 110 for replacement. Therefore, damaged inserts 120 can be replaced.
[0032] Optionally, the hardness of the materials used for the toothed plate 130, the spacer 140, and the insert 120 is not less than HRC50, thus enabling the toothed plate 130, spacer 140, and insert 120 to have suitable resistance to plastic deformation. Optionally, the hardness of the substrate 110 is not greater than HB200 and not less than HB180. The hardness of HB200 and HB180 is approximately less than HRC20. This facilitates the processing and shaping of the substrate 110.
[0033] Optionally, the hardness of the materials of the toothed plate 130, the spacer 140, and the insert 120 may not exceed HRC58, but is not limited thereto. In other examples, the hardness of the materials of the toothed plate 130, the spacer 140, and the insert 120 may exceed HRC58.
[0034] For example, and not as a limitation, the materials of the toothed plate 130, the spacer 140, and the insert 120 are 65Mn steel or SK5 steel. The material of the needle plate 100 is 50# steel plate or 45# steel plate, but not limited to these.
[0035] Furthermore, combined Figures 1-5 See Figures 7-8 The toothed plate 130 has a top protrusion 131 extending from the top of the spacer 140. The substrate 110 includes a first positioning wire 150, a second positioning wire 160 and a third positioning wire 170.
[0036] A first positioning wire 150 is detachably connected to the substrate 110 and extends laterally to pass through the spacers 140 and toothed plates 130 within the plurality of slots 111. A second positioning wire 160 is detachably connected to the substrate 110 and extends laterally to pass through the inserts 120 within the plurality of slots 111. A third positioning wire 170 is detachably connected to the substrate 110 and extends laterally to pass through the top protrusions 131 of the toothed plates 130 within the plurality of slots 111.
[0037] By using the above method, the connection strength between corresponding structures within the needle plate 100 can be improved by using positioning steel wires, thereby further enhancing the ability to resist plastic deformation.
[0038] Optionally, combined Figures 1-4 See Figure 5 In one example, the left and right sides of the distribution area formed by multiple strip grooves 111 are respectively provided with wire positioning grooves 113 corresponding to the first positioning wire 150 and the second positioning wire 160. The first positioning wire 150 and the second positioning wire 160 are detachably disposed in their respective wire positioning grooves 113. In this way, the first positioning wire 150 and the second positioning wire 160 can be detachably connected to the substrate 110, but this is not the only possibility.
[0039] Optionally, combined Figure 4 and Figure 7 See Figure 8 The top protrusion 131 is provided with a first through hole 132 and a second through hole 133, the diameter of the first through hole 132 being larger than the diameter of the second through hole 133. The center of the first through hole 132 is located below the center of the second through hole 133, and the lower side of the first through hole 132 communicates with the upper side of the second through hole 133. The third positioning wire 170 includes a first sub-wire 171 and a second sub-wire 172.
[0040] The outer diameter of the first sub-wire 171 is larger than the outer diameter of the second sub-wire 172. The first sub-wire 171 extends horizontally and passes through the first through hole 132, and the second sub-wire 172 extends horizontally and passes through the second through hole 133. The second sub-wire 172 and the first sub-wire 171 are arranged side by side and in contact, such that the first sub-wire 171 abuts against the second sub-wire 172 from above.
[0041] In this way, firstly, by using the first sub-wire 171 to support the second sub-wire 172, deformation of the first sub-wire 171 can be prevented, thus protecting the first sub-wire 171. Secondly, since the second sub-wire 172 and the first sub-wire 171 are separately configured, when the second sub-wire 172 wears out, it can be directly replaced with the second sub-wire 172 with the smaller outer diameter, thereby saving costs.
[0042] Optionally, combined Figure 4 and Figure 7 See Figure 8 Damping protrusions 139 are provided on both sides of the connection between the first through hole 132 and the second through hole 133, protruding towards the connection between the first through hole 132 and the second through hole 133. The damping protrusions 139 support the second sub-steel wire 172 upwards. This can further improve the support effect on the second sub-steel wire 172. However, it is not limited to this, and the damping protrusions 139 may not be provided in other examples.
[0043] Preferably, the first perforation 132 and the second perforation 133 are disposed near the edge of the top protrusion 131. The vertical distance between the portion of the edge of the top protrusion 131 adjacent to the edge of the first perforation 132 and the edge of the first perforation 132 is a first distance. The vertical distance between the portion of the edge of the top protrusion 131 adjacent to the edge of the second perforation 133 and the edge of the second perforation 133 is a second distance. Wherein, the first distance is greater than the second distance.
[0044] By employing the above method, utilizing a first distance greater than a second distance has at least two beneficial effects. Firstly, the relatively smaller outer diameter of the second sub-wire 172 allows it to be closer to the edge of the toothed plate 130, supporting the toothed plate 130. Secondly, the relatively larger inner diameter of the first perforation 132 allows it to be further away from the edge of the toothed plate 130, thus preventing cracking at the edge of the toothed plate 130. Combining these two aspects, the mechanical strength of the edge of the toothed plate 130 can be effectively enhanced, thereby improving the toothed plate 130's resistance to plastic deformation.
[0045] In addition, it is worth mentioning that the second sub-wire 172, which has a relatively smaller outer diameter, is positioned closer to the edge of the top protrusion 131 than the first sub-wire 171, which has a relatively larger outer diameter. This makes it easier for the edge of the top protrusion 131 to form a rounded corner that is compatible with finer needles, thus facilitating the knitting with finer yarns.
[0046] Optionally, combined Figure 9 See Figure 7 The toothed plate 130 is provided with a clamping arm 134, which is located on the side of the toothed plate 130 facing the substrate 110. The clamping arm 134 is connected to the top of the toothed plate 130 and forms a substrate clamping groove 135 with the toothed plate 130. The substrate clamping groove 135 clamps the top of the substrate 110.
[0047] The clamping arm 134 has a positioning block 136 protruding into the substrate clamping groove 135 at its tail end, and a toothed plate positioning groove 114 is provided on the top of the substrate 110. The toothed plate positioning groove 114 is located on the side of the substrate 110 opposite to the toothed plate 130, and the positioning block 136 is located in the toothed plate positioning groove 114 and clamps the substrate 110. With the above orientation, the positioning of the toothed plate 130 can be strengthened by using the positioning block 136 in conjunction with the toothed plate positioning groove 114.
[0048] Furthermore, combined Figure 9 See Figure 7 The toothed plate 130 extends downward and has an insert portion 137. The insert portion 137 is disposed within the insertion groove 112 and includes a lower extension portion 1371, an elastic connecting portion 1372, and a pressing protrusion 1373. The lower extension portion 1371 is connected to the toothed plate 130 and extends downward. The elastic connecting portion 1372 is disposed at the lower end of the lower extension portion 1371 and extends upward to form a deformation reserved groove 1374 with the lower extension portion 1371. The pressing protrusion 1373 is disposed at the upper end of the elastic connecting portion 1372 and protrudes from the side of the elastic connecting portion 1372 opposite to the deformation reserved groove 1374. The deformation reserved groove 1374 provides a buffer space for the elastic connecting portion 1372 so that the pressing protrusion 1373 elastically presses against the insert piece 120. By using the above method, the toothed plate 130 can be pre-tightened by the elastic pressing of the pressing protrusion 1373 against the insert 120, making the toothed plate 130 less prone to loosening.
[0049] Furthermore, combined Figure 9 See Figure 7 The toothed plate 130 is provided with a retaining portion 138, which is located on the side of the insert portion 137 away from the substrate 110 and above the insert piece 120. The retaining portion 138 abuts against the insert piece 120 to support the toothed plate 130. In this way, the toothed plate 130 can be further improved to resist plastic deformation.
[0050] See Figure 10 and Figure 11 The collar knitting machine 200 of this application includes a collar knitting machine body 210, a front needle plate 220 and a rear needle plate 230. The front needle plate 220 and the rear needle plate 230 are disposed on the collar knitting machine body 210, and both the front needle plate 220 and the rear needle plate 230 are the aforementioned needle plate 100.
[0051] The front needle plate 220 and the rear needle plate 230 are distributed along the front-rear direction, and the top of the front needle plate 220 and the top of the rear needle plate 230 are arranged facing each other, so that the front needle plate 220 and the rear needle plate 230 are inclined towards each other. A gap is formed between the top of the front needle plate 220 and the top of the rear needle plate 230 for the fabric to pass through.
[0052] Optionally, in one example, the collar knitting machine 200 is a jacquard collar knitting machine, including but not limited to an M-type jacquard collar knitting machine. The fabric woven by the collar knitting machine 200 has a smoother fabric surface than the fabric woven by a sweater machine.
[0053] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
