Abstract
Description
Technical Field
[0001] This utility model relates to flat knitting machine equipment, and more specifically, to a flat knitting machine needle plate structure and a needle plate assembly. Background Technology
[0002] The needle plate is a core component of computerized flat knitting machines and other similar equipment. It houses inserts, spacers, and other components via needle slots, and then the knitting needles. Working in conjunction with a cam mechanism, the needles are driven to rise and fall rhythmically to complete the knitting loops. To improve the knitting effect of the flat knitting machine, the design increases the density of the needle arrangement, i.e., the number of needles per unit length, typically 7 or 9 needles. Correspondingly, a corresponding number of needle slots are created on the needle plate.
[0003] As the density of the needle arrangement increases, the spacing between adjacent needle slots will decrease, and the thickness of the separator formed between adjacent needle slots will also become thinner, resulting in a decrease in the strength performance of the separator. Especially at the upper edge of the needle plate, the separator is in a suspended state, which is prone to bending deformation or even breakage, affecting the stability and smoothness of the flat knitting machine.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a needle plate structure and needle plate assembly for a flat knitting machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A pin plate structure for a flat knitting machine includes a pin plate for oblique mounting on a pin bed base. The upper surface of the pin plate has several pin grooves (first and second), spaced apart. The pin plate has an upper side edge, and the pin grooves (first and second) extend through the side edge. A partition is formed between adjacent pin grooves (first and second). At the upper side edge, the partitions on both sides of pin groove (first) separate from each other, forming a through-hole extending from the upper surface of the pin plate to the lower surface. The partitions on both sides of pin groove (second) are integrally connected by a connecting part.
[0008] The present invention is further configured such that the connecting part is located on the lower surface of the separator near the needle plate.
[0009] The present invention is further configured such that the connecting part gradually thickens towards the upper edge of the needle plate, and the connecting part and the bottom support of the needle groove are connected by an arc-shaped transition part.
[0010] The present invention is further configured such that the width of the first needle groove and the second needle groove are the same, and the first needle groove and the second needle groove are equidistant.
[0011] The present invention is further configured such that the thickness of each separator is uniform.
[0012] The present invention is further configured such that there are two needle plates, both of which are fixedly installed on the needle bed base, and the upper edges of the two needle bed bases are close to each other.
[0013] This utility model has the following beneficial effects:
[0014] By connecting the separators on both sides of the needle groove as a single unit, the strength performance between the separators can be increased, allowing the two separators to share the load and improving their strength performance. This also allows the separators to be processed to be thinner, meaning the distance between two adjacent needle grooves can be smaller, enabling the needles to be installed more tightly on the needle plate and increasing the number of needles per unit length.
[0015] This utility model also provides a needle plate assembly, which adopts the needle plate structure of the flat knitting machine as described above, and further includes several spacers one and two, wherein the spacers one are embedded in the needle groove one, and the spacers two are embedded in the needle groove two.
[0016] The present invention is further configured such that a lower extension is fixedly connected to the lower side of the upper end of the first partition, and the lower extension extends from the through-hole to the lower side of the needle plate.
[0017] The present invention is further configured such that the lower extension portion abuts against and is adapted to the lower surface of the needle plate.
[0018] This utility model has the following beneficial effects:
[0019] Since the needle plate assembly includes the aforementioned flat knitting machine needle plate structure, it also possesses all the beneficial effects of the aforementioned flat knitting machine needle plate structure. Furthermore, suitable spacers one and two can be installed within needle slot one and needle slot two, thereby ensuring that spacers can be installed in the corresponding needle slots to separate the knitting needles. A lower extension on the lower side of the spacer can extend out of needle slot one and extend between the upper edges of the two needle plates, guiding the knitted fabric and also functioning as a spacer in a conventional flat knitting machine.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] This embodiment discloses a needle plate structure for a flat knitting machine, referring to... Figures 1-8 As shown, the device includes a needle plate 2, which can be tilted and fixedly installed on the needle bed base 1 during installation. There are two needle plates 2 on the needle bed base 1, both of which are fixedly installed on the needle bed base 1, and the upper edges 21 of the two needle bed bases 1 are close to each other and symmetrically distributed.
[0033] The upper surface 22 of the needle plate 2 is provided with several needle grooves 1 23 and needle groove 24, which are spaced apart. Figure 1 The upper surface 22 of the needle plate 2 is densely covered with needle grooves 23 and 24, only a portion of which are shown in the figure for illustration.
[0034] The needle plate 2 has an upper side edge 21, and needle groove 1 23 and needle groove 24 extend through the side edge 21. A partition 25 is formed between adjacent needle groove 1 23 and needle groove 24, and the partition 25 is integrally connected and fixed to the main body of the needle plate 2.
[0035] In this embodiment, the widths of needle groove 1 23 and needle groove 24 are the same, and needle groove 1 23 and needle groove 24 are equidistant, thereby enabling knitting needles to be evenly installed on the upper side of the needle plate 2. Correspondingly, the distance between adjacent needle groove 1 23 and needle groove 24 is the thickness of the separator 25, and the thickness of each separator 25 is also the same.
[0036] Reference Figures 4-6 As shown, at the upper edge 21, the partition plates 25 on both sides of the needle groove 23 are separated from each other, forming a through-hole 231 that extends from the upper surface 22 of the needle plate 2 to the lower surface 27 of the needle plate 2. The partition plates 25 on both sides of the needle groove 24 are integrally connected by a connecting part 26, which can increase the strength performance between the partition plates 25.
[0037] When more needles need to be installed on the needle plate 2, the density of the needle groove arrangement needs to be increased, and the thickness of the spacer 25 formed between the needle grooves will also become thinner, which will reduce the strength performance of the spacer 25. Especially at the upper edge of the needle plate, the spacer is in a suspended state, which is prone to bending deformation or even breakage, affecting the stability and smoothness of the flat knitting machine.
[0038] In this embodiment, two adjacent separators 25 are integrally connected by the connecting part 26, so that the two separators 25 can share the load, improve the strength performance of the separators 25, and make the separators 25 thinner, that is, the distance between two adjacent needle grooves can become smaller, so that the needles can be installed more tightly on the needle plate 2, and increase the number of needles per unit length.
[0039] Reference Figure 4 , Figure 6 As shown, the connecting portion 26 is located on the side of the separator 25 near the lower surface 27 of the needle plate 2, and the connecting portion 26 can integrally connect the separators 25 on both sides. The connecting portion 26 gradually thickens towards the upper edge 21 of the needle plate 2, and the connecting portion 26 and the bottom support of the needle groove 24 are connected by an arc-shaped transition portion 261. The arc-shaped transition structure can not only meet the connection strength of the connecting portion 26 to the separators 25 on both sides, but also form an arc transition to improve the connection strength performance between adjacent separators 25.
[0040] This embodiment also discloses a needle plate assembly, which is based on the above embodiment and further refers to... Figure 7 , Figure 8Detailed explanation follows. Adaptive spacers 3 and 4 can be installed in needle groove 1 23 and needle groove 2 24, thereby ensuring that spacers can be installed in the corresponding needle grooves to separate the knitting needles.
[0041] In this embodiment, the needle plate assembly includes the flat knitting machine needle plate structure in the above embodiment, and also includes a plurality of spacers 3 and 4. Spacers 3 correspond one-to-one with needle grooves 23, and spacers 4 correspond one-to-one with needle grooves 24. Spacers 3 are embedded in needle grooves 23, and spacers 4 are embedded in needle grooves 24. Spacers 3 and 4 can serve to separate and guide the knitting needles.
[0042] A lower extension 31 is fixedly connected to the lower side of the upper end of the spacer 3. The lower extension 31 extends from the opening 231 to the lower side of the needle plate 2. A notch is formed between the main body of the spacer 3 and the lower extension 31, allowing part of the needle plate 2 to be inserted between the main body of the spacer 3 and the lower extension 31. The lower extension 31 and the lower surface 27 of the needle plate 2 abut against each other, enabling stable installation of the spacer 3.
[0043] The lower extension 31 is located between the upper edges 21 of the two needle plates 2 and can guide the woven fabric; in addition, the second spacer 4 does not extend into the lower side of the needle plate 2.
[0044] Furthermore, referring to Figure 9 , Figure 10 As shown, to improve the strength of the upper edge 21 of the needle plate 2, a through hole 5 can be made near the upper edge 21 of the needle plate 2. The through hole 5 extends along the width direction of the needle plate 2, passing through each separator 25. A fixed shaft (not shown in the figure) passes through the through hole 5. The fixed shaft passes through the through hole 5 and can connect each separator 25 together. The separator 25 and the fixed shaft can transfer loads to each other, and the force on each separator 25 can be connected into a whole, thereby improving the stability of the force.
[0045] Furthermore, the through hole 5 is located at the connecting part 26, so that when the fixed shaft passes through the through hole 5, there is a force contact between the outer periphery of the fixed shaft and the connecting part 26, which increases the force contact area between the connecting part 26 and the needle plate 2, thereby improving the stability of the force and enhancing the strength performance of the upper edge 21 of the needle plate 2.
[0046] In addition, due to the presence of the through hole 5 and the fixed shaft, corresponding holes are also provided at the corresponding positions of the partition 3 and the partition 4. The fixed shaft can also connect the partition 3 and the partition 4 in series, which can improve the installation stability of the partition 3 and the partition 4 to a certain extent.
[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
