Description

Technical Field

[0001] This utility model relates to the field of bottom-raising plate technology, specifically to an integrated bottom-raising needle plate. Background Technology

[0002] The cast-on needle plate on a computerized flat knitting machine is a key component ensuring efficient and stable fabric casting-on stage. Its core function is to hook the initially knitted yarn with the cast-on needles and provide tension, reducing waste yarn to save costs, accelerating the start-up speed on an empty machine to improve efficiency, and allowing garment pieces to form independently for easier subsequent processing. Existing cast-on needle plates consist of a needle plate body and cast-on needles welded to the body. Welded cast-on needles have relatively poor strength and stability, resulting in a shorter lifespan and increased maintenance frequency. Therefore, this invention provides an integrated cast-on needle plate. Utility Model Content

[0003] The purpose of this invention is to provide an integrated bottom-opening needle plate.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] An integrated bottom-pinning plate includes: bottom-pinning plate units and connecting buckles; the number of bottom-pinning plate units is several, which are spliced ​​together along a straight line to form a bottom-pinning plate; the connecting buckles are disposed between two adjacent bottom-pinning plate units to restrict the vertical relative movement between the two adjacent bottom-pinning plate units;

[0006] The bottom-opening needle plate unit includes an integrally formed bottom-opening needle plate body and bottom-opening needles; the number of bottom-opening needles is several, which are evenly distributed along the length direction of the bottom-opening needle plate body and are arranged at the top of the bottom-opening needle plate body, and the top of the bottom-opening needles is provided with through holes.

[0007] Both sides of the bottom needle plate body are provided with connecting half grooves; when two adjacent bottom needle plate units are spliced ​​together, the two connecting half grooves are combined to form a connecting groove; the connecting buckle has an I-shaped cross section, with the middle part fitting into the connecting groove, and the upper and lower parts clamped on the upper and lower sides of the bottom needle body.

[0008] The first side end of the bottom needle plate body is provided with a limiting protrusion, and the second side end is provided with a limiting groove corresponding to the limiting protrusion.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the tip of the bottom-opening needle has an arc structure.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme, the connecting half groove is semi-circular, making the connecting groove circular; the middle part of the connecting buckle is a cylindrical structure adapted to the connecting groove.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme, the number of the limiting protrusions (15) is at least two.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: The bottom needle plate of this utility model is composed of several bottom needle plate units spliced ​​together. The bottom needle plate includes an integrally formed bottom needle plate body and bottom needles. Compared with the existing structure where the bottom needles are welded to the bottom needle plate body, it is more stable and firm, less prone to falling off, and has better planar consistency. During processing, the bottom needles are formed by cutting on the bottom needle plate body using a cutting device. Compared with the traditional steps of separate processing, needle arrangement, and needle welding, the production and processing is more convenient, and the mass production cost is low and the efficiency is high. Adjacent bottom needle plate bodies are connected by a connecting buckle and the cooperation of the limiting protrusion and the limiting groove, which is simple in structure and easy to connect.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0018] like Figure 1 As shown, an integrated bottom-pinning plate includes: a bottom-pinning plate unit 1 and a connecting buckle 2. Several bottom-pinning plate units 1 are assembled along a straight line to form the bottom-pinning plate. The connecting buckle 2 is disposed between two adjacent bottom-pinning plate units 1 to restrict vertical relative movement between adjacent bottom-pinning plate units 1.

[0019] Among them, such as Figure 2 and Figure 3 As shown, the bottom pin plate unit 1 includes an integrally formed bottom pin plate body 11 and bottom pins 12. Several bottom pins 12 are evenly distributed along the length of the bottom pin plate body 11 at its top end, and each bottom pin 12 has a through hole 13 at its top. The integral forming process includes: using laser cutting equipment to cut several spaced slots on the plate, leaving space between adjacent slots for the bottom pins; and then using electrical discharge machining (EDM) to create through holes 13 at the top of the bottom pins. The integral forming of the bottom pins 12 and the bottom pin plate body 11 provides higher stability, extends the service life of the bottom pin plate, and reduces maintenance frequency. Simultaneously, the bottom pin plate unit 1 divides the bottom pin plate into several sections for easier processing and transportation. When a bottom pin is damaged, only one bottom pin plate unit 1 needs to be replaced, reducing maintenance costs.

[0020] The tip of the bottom pin 12 has a rounded structure to reduce its sharpness. In this embodiment, the one-piece bottom pin plate is made by directly cutting strips into a comb shape on the original pin plate body, drilling and piercing it with a machine tool, and then grinding the edges to form the bottom pin. The bottom pins produced by this process are more robust and stable than those produced by traditional welding processes, and the production efficiency is higher. Traditional bottom pin production, from processing to pin arrangement and welding, is slow and costly. The one-piece bottom pin is formed by cutting, drilling, grinding and polishing, which can eliminate the cumbersome processes of separate processing, pin arrangement and welding of bottom pins, resulting in low cost and high efficiency in mass production.

[0021] Both sides of the bottom needle plate body 11 are provided with connecting half-grooves 14. When two adjacent bottom needle plate units 1 are spliced, the two connecting half-grooves 14 are combined to form a connecting groove. The connecting buckle 2 has an I-shaped cross-section, with its middle part fitting into the connecting groove, and its upper and lower parts clamping the upper and lower sides of the bottom needle plate body 11 to restrict the vertical relative movement between adjacent bottom needle plate bodies 11. Preferably, the connecting half-grooves 14 are semi-circular, and the resulting connecting groove is circular. The middle part of the connecting buckle 2 has a cylindrical structure that matches the connecting groove. In addition, both the upper and lower parts of the connecting buckle 2 are circular, with a diameter larger than the diameter of the cylindrical structure in the middle.

[0022] The first side end of the bottom needle plate body 11 is provided with a limiting protrusion 15, and the second side end is provided with a limiting groove 16 corresponding to the limiting protrusion 15. When two bottom needle plate units 1 are spliced ​​together, the cooperation of the limiting protrusion 15 and the limiting groove 16 can restrict the longitudinal relative movement of the two adjacent bottom needle plate bodies 11.

[0023] Meanwhile, the lateral relative movement of two adjacent bottom-starting needle plate bodies 11 is restricted by the interaction between the adjacent bottom-starting needle plate bodies 11, so that the horizontal, vertical and longitudinal movement of the bottom-starting needle plate bodies 11 after splicing is restricted, thus achieving position fixation.

[0024] The number of limiting protrusions 15 is at least two.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
