Description

Technical Field

[0001] This utility model relates to the field of horizontal knitting machine technology, and in particular to a combined needle plate for a horizontal knitting machine. Background Technology

[0002] In the knitting process of a flat knitting machine, the needle plate, as a key component for mounting the knitting needles, directly affects the quality of the fabric and production efficiency. Traditional flat knitting machines typically use a one-piece needle plate structure, where the needle plate teeth and base plate are molded as a single unit. This cannot accommodate the installation requirements of different needle types or meet the knitting needs of fabrics of different specifications. After prolonged use, the needle plate teeth are prone to wear or deformation, leading to a decrease in precision. The one-piece structure requires replacement of the entire needle plate, resulting in high maintenance costs and material waste. Furthermore, the one-piece needle plate requires high hardness of the teeth, involves complex overall heat treatment processes, and cannot be individually repaired after localized wear, resulting in a short needle plate lifespan.

[0003] Therefore, it is necessary to design a product that can solve the problems of poor applicability and high maintenance costs in existing needle plates, and improve the multi-functional use and service life of needle plates. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a combined needle plate for a horizontal knitting machine.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A combination needle plate for a horizontal knitting machine includes a bottom needle plate with multiple toothed slots and toothed plates. The upper and lower rear ends of the toothed plates extend rearward to form upper and lower corresponding locking strips. The front part of the toothed plate engages with and is inserted into the toothed slots. The upper and lower locking strips engage with the upper and lower surfaces of the bottom needle plate, respectively, and are snapped together.

[0007] Preferably, the upper surface of the bottom pin plate is provided with an upper positioning groove, and the upper clip is provided with an upper positioning protrusion that cooperates with the upper positioning groove.

[0008] Preferably, the lower surface of the bottom pin plate is provided with a lower positioning groove, and the lower locking strip is provided with a lower positioning protrusion that cooperates with the lower positioning groove.

[0009] Preferably, a positioning hole is provided above the upper positioning protrusion.

[0010] Preferably, the front end of the upper positioning protrusion is provided with an upper arc-shaped groove, the radius of which is 0.2–0.5 mm. The design of the upper arc-shaped groove can disperse stress during the snapping process and prevent the toothed piece from breaking after multiple snapping.

[0011] Preferably, the lower positioning protrusion has a lower arc-shaped groove at its front end, with a radius of 0.4–0.7 mm. The upper arc-shaped groove design can disperse stress during the snapping process and prevent the toothed piece from breaking after multiple snaps.

[0012] Preferably, the front part of the toothed plate is provided with two toothed wire holes distributed front and back. The diameter of the toothed wire holes matches the positioning wire. Wires are threaded through different toothed wire holes, and the size of the needle plate opening is adjusted by the different positions of the wires.

[0013] As a preferred option, a dovetail groove, a needle selection plate limiting groove, and a needle selector clearance groove are also provided behind the toothed slot.

[0014] Preferably, the bottom needle plate is provided with evenly distributed needle grooves, and the needle grooves and toothed slots are arranged alternately. The needle grooves are arranged at a certain needle spacing to install different types of knitting needles.

[0015] This utility model, by adopting the above technical solutions, has significant technical effects: By installing steel wires in different toothed wire holes, the size of the needle plate opening can be adjusted in stages, adapting to the installation needs of various needle types; the bottom needle plate and the toothed plates are set separately, and the toothed plates are made of high-hardness material, solving the problem of insufficient hardness of the teeth in integral needle plates; positioning steel wires pass through the positioning holes of each toothed plate, ensuring consistent installation positions and avoiding uneven teeth due to installation errors; when the teeth in a certain area of ​​the needle plate are worn, the toothed plates in that area can be disassembled and replaced individually without replacing the entire needle plate, reducing maintenance costs.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] A combination needle plate for a horizontal knitting machine, as shown in the figure, includes a bottom needle plate 1 with multiple toothed slots 11 and toothed plates 2. The upper and lower rear ends of the toothed plates 2 extend rearward to form upper and lower corresponding upper retaining strips 3 and lower retaining strips 4. The front part of the toothed plate 2 engages with and is inserted into the toothed slots 11. The upper retaining strips 3 and lower retaining strips 4 engage with the upper and lower surfaces of the bottom needle plate 1 respectively and are fastened.

[0025] Example 2

[0026] Same as in Example 1, such as Figure 4 The difference is that the upper surface of the bottom pin plate 1 is provided with an upper positioning groove 12, and the upper clip 3 is provided with an upper positioning protrusion 31 that cooperates with the upper positioning groove 12.

[0027] A positioning hole 5 is provided above the upper positioning protrusion 31.

[0028] The upper positioning protrusion 31 has an upper arc-shaped groove 32 at its front end, and the radius of the upper arc-shaped groove 32 is 0.35mm. The design of the upper arc-shaped groove 32 can disperse stress during the snapping process and prevent the toothed piece 2 from breaking after multiple snapping.

[0029] The lower surface of the bottom pin plate 1 is provided with a lower positioning groove 13, and the lower locking strip 4 is provided with a lower positioning protrusion 41 that cooperates with the lower positioning groove 13.

The design of the upper arc-shaped groove 42 can disperse stress during the snapping process and prevent the toothed piece 2 from breaking after multiple snapping.

[0031] Example 3

[0032] Same as in Example 1, such as Figure 5The difference is that the upper locking strip 3 does not have an upper positioning protrusion 31 that cooperates with the upper positioning groove 12. The upper locking strip 3 is just a long rectangular structure, while the lower surface of the bottom pin plate 1 has a lower positioning groove 13, and the lower locking strip 4 has a lower positioning protrusion 41 that cooperates with the lower positioning groove 13.

[0033] The lower positioning protrusion 41 has a lower arc-shaped groove 42 at its front end. The design of the upper arc-shaped groove 42 can disperse stress during the snapping process and prevent the toothed piece 2 from breaking after multiple snapping.

[0034] Example 4

[0035] Similar to Example 1, except that the front of the toothed plate 2 is provided with two toothed wire holes 6 distributed front and back. The diameter of the toothed wire holes 6 matches the positioning wire. Wires are threaded through different toothed wire holes 6, and the size of the needle plate opening is adjusted by the different positions of the wires.

[0036] Example 5

[0037] Similar to Embodiment 1, except that a dovetail groove 14, a needle selection plate limiting groove 15, and a needle selector clearance groove 16 are also provided behind the toothed groove 11.

[0038] Example 6

[0039] Similar to Embodiment 1, except that the bottom needle plate 1 is provided with uniformly distributed needle grooves 17, and the needle grooves 17 and the toothed grooves 11 are arranged alternately in sequence. The needle grooves are arranged according to a certain needle spacing and are used to install different types of knitting needles.
