[0001] This application relates to the field of computerized flat knitting machine technology, and in particular to a needle plate structure and a computerized flat knitting machine. Background Technology

[0002] The needle plate of a computerized flat knitting machine is a structure used to place knitting needles. It usually includes a needle plate and baffles. Multiple baffles are evenly installed on the needle plate, so that needle grooves are formed between adjacent baffles. Knitting needles are installed in the needle grooves and can move relative to the needle grooves.

[0003] Computerized flat knitting machines have strict requirements for the center distance of the needle slots. The needle slots are formed by adjacent insert plates. Currently, in order to meet the requirements for the center distance of the needle slots, the thickness of the needle slots has been reduced, which in turn reduces the thickness of the knitting needles, affecting the strength of the knitting needles and the operational stability of the computerized flat knitting machine. Utility Model Content

[0004] This application provides a needle plate structure and a computerized flat knitting machine, which increases the thickness of the needle groove, thereby increasing the thickness of the knitting needle and improving the operational stability of the computerized flat knitting machine.

[0006] Furthermore, along the thickness direction of the needle plate, the end face of the insertion part facing the knitting needle is not higher than the end face of the needle plate facing the knitting needle.

[0007] Furthermore, the auxiliary insert plate includes a limiting part and an auxiliary insert plate body. The limiting part is connected to the auxiliary insert plate body on the side facing the needle plate.

[0008] Furthermore, along the first direction, the size of the limiting part is larger than the size of the sub-insertion plate body, and the sub-insertion plate body is connected to the middle of the limiting part.

[0009] Furthermore, the needle plate also includes a slot that extends along a first direction; a limiting part is installed in the slot.

[0010] Furthermore, along the thickness direction of the needle plate, the end face of the limiting part facing the knitting needle is not higher than the end face of the needle plate facing the knitting needle.

[0011] Furthermore, the knitting needle includes a knitting needle body and a drive unit. Along the second direction, the drive unit is connected to one side of the knitting needle body. A first relief groove is formed on the side of the auxiliary insert plate facing the knitting needle body, and the knitting needle body is at least partially located in the first relief groove.

Detailed Implementation

[0026] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, as one implementation, this application provides a needle plate structure, including a needle plate 1, multiple main insert plates 2, multiple auxiliary insert plates 3, and knitting needles 4. The needle plate is used to install the main insert plates 2 and auxiliary insert plates 3. The main insert plates 2 and auxiliary insert plates 3 are used to enclose and form a needle groove. The knitting needles 4 are placed in the needle groove and can move within the needle groove so that the knitting needles 4 can hook the yarn.

[0030] Multiple main insert plates 2 are evenly installed on the needle plate 1 along the first direction.

[0031] Multiple auxiliary plates 3 are arranged along the first direction, and each auxiliary plate 3 is placed between adjacent main plates 2, so that the main plates 2 and auxiliary plates 3 are spaced apart, and a pin groove is formed between adjacent main plates 2 and auxiliary plates 3, and the pin groove extends along the second direction.

[0032] The knitting needle 4 is placed in the needle groove and has the degree of freedom to move relative to the needle groove in the second direction. By moving the knitting needle 4 in the second direction, the yarn hooking is realized in the working process of the computer flat knitting machine.

[0033] The needle plate 1 includes multiple slots 101, the main insert plate 2 is installed on the needle plate 1 through the slots 101, and the auxiliary insert plate 3 is placed between adjacent main insert plates 2.

[0034] It should be noted that the needle plate 1 is only provided with a slot 101 for the main insert plate 2, reducing the number of slots for the auxiliary insert plate 3, thereby improving the overall strength of the needle plate 1.

[0035] like Figure 2 and Figure 5 As shown, along the thickness direction of the needle plate 1, the main insert plate 2 includes an insertion part 201 and a main insert plate body 202. The insertion part 201 is connected to the main insert plate body 202 on the side facing the needle plate 1, and the insertion part 201 is inserted into the slot 101. The main insert plate body 202 and the auxiliary insert plate 3 together form a needle groove. The insertion part 201 is used to install the main insert plate 2 onto the needle plate 1.

[0036] Along the first direction, the size of the insertion part 201 is larger than the size of the main insertion plate body 202. By reducing the size of the main insertion plate body 202, the size of the needle groove along the first direction is increased, thereby increasing the thickness of the knitting needle 4 along the first direction, improving the strength of the knitting needle 4, and thus improving the operational stability of the computerized flat knitting machine.

[0037] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The directions shown are up, down, left, right, front, and back. The first direction is... Figure 1 The left and right directions are shown. The second direction is... Figure 1 The front-to-back direction is shown. The thickness direction of needle plate 1 is... Figure 1 The vertical direction is shown. The first direction, the second direction, and the thickness direction of the needle plate 1 are perpendicular to each other.

[0038] like Figure 3 and Figure 5 As shown, in one implementation, along the first direction, the plug-in portion 201 and the main plug plate body 202 are coplanar on one side, and a step is formed on the other side of the plug-in portion 201 and the main plug plate body 202.

[0039] It should be noted that the sides of each main insert plate 2 that form the steps are consistent, that is, the steps are uniformly formed on the side of the main insert plate 2 facing the left or the side facing the right.

[0040] As another implementation, along the first direction, the main insert plate body 202 is connected to the middle of the insertion part 201, that is, steps are formed on both the left and right sides of the main insert plate 2.

[0041] It should be noted that this application describes the insertion part 201 and the main insertion plate body 202 as having one coplanar surface.

[0042] As one implementation, along the thickness direction of the needle plate 1, the end face of the insertion part 201 facing the knitting needle 4 is not higher than the end face of the needle plate 1 facing the knitting needle 4, so as to prevent the end face of the insertion part 201 facing the knitting needle 4 from affecting the movement of the knitting needle 4 and improve the movement stability of the knitting needle 4.

[0043] It should be noted that the end face (upper end face) of the needle plate 1 facing the knitting needle 4 consists of multiple planes of different heights, and the end face (upper end face) of the insertion part 201 facing the knitting needle 4 also consists of multiple planes of different heights.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, in one implementation, the auxiliary insert plate 3 includes a limiting part 301 and an auxiliary insert plate body 302. The limiting part 301 is connected to the auxiliary insert plate body 302 on the side facing the needle plate 1. Along the first direction, the two sides of the limiting part 301 abut against the main insert plate 2 respectively. By the limiting part 301 abutting against the main insert plate 2, the position between the auxiliary insert plate 3 and the main insert plate 2 is fixed, thereby forming a stable needle groove.

[0045] The limiting part 301 is located outside the needle groove and below the needle groove, ensuring the dimensional accuracy of the needle groove near the knitting needle 4, thereby improving the movement stability of the knitting needle 4.

[0046] As one implementation, along the first direction, the size of the limiting part 301 is larger than the size of the sub-insertion plate body 302. The limiting part 301 abuts against the main insertion plate body 202, positioning the sub-insertion plate 3 between adjacent main insertion plates 2, and ensuring that a pin groove is formed between the sub-insertion plate body 302 and the main insertion plate body 202.

[0047] The auxiliary insert plate body 302 is connected to the middle of the limiting part 301 to ensure that the pin grooves on both sides of the auxiliary insert plate body 302 have the same size along the first direction.

[0048] Meanwhile, by reducing the size of the auxiliary insert plate body 302 along the first direction, the size of the needle groove along the first direction can be further increased, thereby increasing the thickness of the knitting needle 4 along the first direction, improving the strength of the knitting needle 4, and thus improving the operational stability of the computerized flat knitting machine.

[0049] like Figure 1 As shown, as one implementation, the needle plate 1 also includes a slot 102, which extends along a first direction.

[0050] The limiting part 301 of each sub-insertion plate 3 is installed in the slot 102. The slot 102 restricts the degree of freedom of the sub-insertion plate 3 in the second direction, thereby further improving the installation stability of the sub-insertion plate 3.

[0051] It should be noted that the auxiliary insert plate 3 and the card slot 102 are assembled through a transition fit.

[0052] As one implementation method, the needle plate structure also includes a connector 5, which is connected to both the main insert plate 2 and the secondary insert plate 3. The connector 5 limits the thickness of the needle plate 1 by limiting the secondary insert plate 3.

[0053] As one implementation, along the thickness direction of the needle plate 1, the end face of the limiting part 301 facing the knitting needle 4 is not higher than the end face of the needle plate 1 facing the knitting needle 4, so as to prevent the end face of the limiting part 301 facing the knitting needle 4 from extending into the needle groove, thereby further improving the movement stability of the knitting needle 4.

[0054] As one implementation, the needle plate 1 includes three parallel slots 102.

[0055] The limiting part 301 includes a first limiting block 3011, a second limiting block 3012 and a third limiting block 3013. The first limiting block 3011, the second limiting block 3012 and the third limiting block 3013 are laid flat along the second direction and are respectively connected to the side of the auxiliary insert plate body 302 facing the needle plate 1. The first limiting block 3011, the second limiting block 3012 and the third limiting block 3013 are respectively engaged in three slots 102.

[0056] The upper surface of the first limiting block 3011 is formed with a guide slope 30111. By setting the guide slope 30111, the slot 102 used to install the first limiting block 3011 is prevented from affecting the movement of the knitting needle 4, thereby improving the running stability of the knitting needle 4.

[0057] like Figure 6 and Figure 8As shown, in one implementation, the knitting needle 4 includes a knitting needle body 401 and a driving part 402. Along the second direction, the driving part 402 is connected to one side of the knitting needle body 401. The knitting needle body 401 is used to hook the yarn to form a fabric. The driving part 402 is used to connect with an external driving component. The external driving component drives the driving part 402 to move along the second direction, thereby driving the knitting needle body 401 to hook the yarn.

[0058] In one implementation, a connecting groove 4012 is formed at the end of the needle body 401 facing the drive part 402, and a connecting part 4021 is formed at the end of the drive part 402 facing the needle body 401. The connecting part 4021 engages with the connecting groove 4012, thereby enabling the needle body 401 and the drive part 402 to move simultaneously.

[0059] The auxiliary insert plate 3 has a first relief groove 303 formed on the side facing the needle body 401. The needle body 401 is at least partially located in the first relief groove 303. By setting the first relief groove 303, it is easy to increase the size of the needle body 401 along the first direction, thereby increasing the thickness of the needle body 401, improving the strength of the needle body 401, and thus improving the running stability of the computer flat knitting machine.

[0060] like Figure 6 and Figure 7 As shown, in one implementation, the first relief groove 303 penetrates the auxiliary insert plate 3 along the first direction, and a guide groove is formed between the first relief groove 303 and the needle plate 1, and the knitting needle body 401 slides in the guide groove.

[0061] The two drive parts 402 of two adjacent knitting needles 4 are located on both sides of the auxiliary insert plate 3 to prevent the drive parts 402 of adjacent knitting needles 4 from affecting each other and to improve the stability of the movement of each knitting needle 4.

[0062] The two needle bodies 401 of two adjacent needles 4 move closer to each other, increasing the size of the needle body 401 along the first direction and improving the strength of the needle body 401, thereby improving the operational stability of the computerized flat knitting machine.

[0063] It should be noted that the two needle bodies 401 of two adjacent needles 4 are close to each other, but not completely abutting, to prevent the movement of one needle body 401 from affecting the other needle body 401. At the same time, since the drive units 402 are isolated from each other, the drive unit 402 of each needle 4 is independently connected to the external drive device. That is, the movement of each needle 4 is independently controlled by the external drive device, preventing the accuracy of the needle 4's movement from being affected by the close proximity of the two needle bodies 401 of two adjacent needles 4.

[0064] like Figure 8As shown, as one implementation, the needle body 401 has a second relief groove 4011. By setting the second relief groove 4011, interference between the needle body 401 and the auxiliary insert plate 3 is prevented during the movement of the needle 4, thus ensuring the stability of the movement of the needle 4.

[0065] Along the first direction, the second relief groove 4011 is located on the side of the needle body 401 facing the auxiliary insert plate 3.

[0066] It should be noted that, along the first direction, the second relief groove 4011 does not penetrate the needle body 401. Meanwhile, the second relief grooves 4011 of the two needles 4 located between the two main insert plates 2 are both oriented towards the auxiliary insert plate 3 located between the two main insert plates 2.

[0067] Along the second direction, the second relief groove 4011 is located on the side of the needle body 401 facing the drive unit 402, to prevent the needle body 401 from interfering with the auxiliary insert plate 3 during the movement of the needle 4.

[0068] Secondly, this application also provides a computerized flat knitting machine, including the aforementioned needle plate structure. By increasing the thickness of the knitting needle 4 along the first direction in the needle plate structure, the strength of the knitting needle 4 is improved, thereby enhancing the operational stability of the computerized flat knitting machine.

[0069] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
