AI Technical Summary
Traditional needle plate layout structures are limited by the physical thickness of the three-piece set of components, which prevents the slot spacing from being further compressed, thus failing to meet the needs of high-density knitting. Furthermore, the components are prone to jamming or deformation in confined spaces.
The high-density needle plate layout structure is adopted, and the traditional three-piece set is disassembled into staggered AB double combinations. The slots are alternately set with sinker plates and toothed plates to form a cantilever and closed U-shaped groove structure, ensuring that the needles are densely arranged and the components move without interference.
It achieves double the needle density, eliminates interference in component movement, ensures coil holding function and baffle support stability, breaks through the needle density bottleneck of traditional structures, and has industrial manufacturing capabilities.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat knitting machine technology, specifically to a high-density needle plate layout structure. Background Technology
[0002] In the field of knitting equipment, the traditional needle plate layout structure usually adopts a slot spacing design of about 1 mm. The main reason is that the needle plate structure is limited by the physical thickness of the sinker plate, toothed plate and insert. The three components in a single slot need to occupy at least 0.8 mm of width space, which forces the slot spacing to be maintained at more than 1 mm. This structure encounters a bottleneck in increasing the needle density. If the slot spacing is forcibly compressed, the sinker plate will be stuck, the toothed plate will be deformed and the insert will be dislodged and fail due to space compression. Due to the requirements of metal strength and wear resistance, the thickness of the three components cannot be further compressed. Therefore, the traditional side-by-side mode can no longer meet the physical tolerance. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model relates to a high-density needle plate layout structure. This structure is simple and reliable, effectively solves the above-mentioned technical problems, and is suitable for widespread use. To achieve the above objectives, this utility model is implemented through the following technical solution:
[0004] A high-density needle plate layout structure includes a base plate, on which a plurality of receiving grooves are evenly spaced and parallel to each other in the transverse direction are provided, and a knitting needle is independently arranged in each receiving groove.
[0005] Adjacent slots are alternately equipped with first and second functional units. The first functional unit is composed of a settling plate and a first insert, and the second functional unit is composed of a toothed plate and a second insert. Based on the above scheme and as a preferred embodiment, the spacing between each receiving slot is 0.3-0.4 mm.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the front ends of the baffles on both sides of the slot where the first functional unit is located are milled through to form an independent cantilever structure, and the front ends of the baffles on both sides of the slot where the second functional unit is located are connected as one to form a closed U-shaped slot structure.
[0007] The outstanding and beneficial technical effects of this utility model compared with the prior art are as follows: by disassembling the traditional three-piece set and distributing it to adjacent slots in a staggered manner, the stacking conflict of components in a single slot is eliminated, allowing the knitting needles to be densely arranged to about twice the density of the traditional structure. This directly breaks through the needle count bottleneck of high-precision knitting technology, limits the critical value of the slot spacing to a very small value, ensures the minimum safe structural size of the needle body and the baffle, and provides precise assembly space for the two sets of functional units. This enables the ultra-high density layout to have an industrial manufacturing basis. The open structure at the front end ensures that the sinker moves without interference and ensures the coil holding function. The closed structure at the front end constructs a rigid needle slot and ensures the stability of the baffle support. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0013] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0014] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0015] To solve the above technical problems, such as Figure 1-4As shown, this utility model designs a high-density needle plate layout structure, including a base plate 1. The base plate 1 is provided with several accommodating slots 2 that are evenly spaced laterally and parallel to each other. The two sides of the accommodating slots 2 are baffles 3. Each accommodating slot 2 is independently equipped with a knitting needle. Adjacent slots are alternately equipped with a first functional unit and a second functional unit. The first functional unit is composed of a sinker plate 4 and a first insert plate 5. The second functional unit is composed of a toothed plate 6 and a second insert plate 7. This layout structure completely eliminates the spatial conflict of component stacking in a single slot by deconstructing the traditional three-piece set into a staggered AB double combination, so that adjacent slots share functional areas. This spatial reconstruction scheme achieves needle slot spacing compression under the premise of unchanged total number of parts, directly breaking through the technical ceiling of doubling needle density, enabling the needle plate to support ultra-fine knitting capabilities.
[0016] In this embodiment, it is further preferred that the spacing between each receiving slot 2 is 0.3-0.4mm. The upper limit of 0.4mm ensures that the needle body and the baffle 3 maintain the minimum safe structural strength, and the lower limit of 0.3mm reserves the critical tolerance space for component assembly. By limiting the minimum critical value of the slot spacing, the minimum safe structural size of the needle body and the baffle 3 is guaranteed, and precise assembly space is provided for the two sets of functional units, so that the ultra-high density layout has the basis for industrial manufacturing.
[0017] In this embodiment, it is further preferred that the front ends of the baffles 3 on both sides of the slot where the first functional unit is located are milled through to form an independent cantilever structure, and the front ends of the baffles 3 on both sides of the slot where the second functional unit is located are connected to form a closed U-shaped groove structure. The open front structure completely releases the two-dimensional movement space of the sinker 4, ensuring that the sinker 4 moves without interference, and ensuring the agility and consistency of the coil holding action. The closed front design forms a rigid cage structure to ensure the support stability of the baffle 3, thereby preventing the knitting needle from drifting and swaying laterally during high-speed movement.
[0018] It is worth noting that the technical features such as settling plates, inserts, and toothed plates involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement methods of these technical features can be adopted using conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.
[0019] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
