Description

Technical Field

[0001] The utility model belongs to the technical field of knitting machinery, and relates to a bottom plate of a flat knitting machine, in particular to a bottom plate of a flat knitting machine which can complete warp lining knitting. Background Art

[0002] Flat knitting machines are typically weft knitting machines, using one or more yarns fed continuously along the weft direction of the fabric, forming loops that are then strung together to create a knitted fabric. In contrast, warp knitting machines use one or more parallel yarns fed along the warp direction onto all needles, forming loops simultaneously to create the fabric. Because warp knitted fabrics are woven along the warp direction, the grain on both sides of the fabric is perpendicular to each other; in contrast, the grain on both sides of a weft knitted fabric is consistent.

[0003] The flat knitting machines in the prior art only have the function of weft knitting, and the fabrics are relatively simple. Summary of the Invention

[0004] The purpose of the utility model is to provide a flat knitting machine bottom plate which can complete warp knitting, so that warp knitting tissue can be added into the fabric.

[0005] To this end, the technical solution adopted by the present invention is as follows: a flat knitting machine bottom plate that can complete lining warp knitting includes an upper triangular part and a lower needle selection part. The flat knitting machine bottom plate is symmetrical on the left and right, and guardrails are provided on both sides of its top. The inner side of the guardrail is a needle pressing triangle, and a return needle triangle is provided below the guardrail; it is characterized in that: the guardrail has two needle running surfaces at its lower edge, one of which is above the other needle running surface; the press needle triangle has an independent driving mechanism; a middle guardrail is further provided below the return needle triangle, the upper edge of the middle guardrail cooperates with the lower edge of the return needle triangle, and the lower edge of the middle guardrail has two needle running surfaces, one of which is higher than the other needle running surface.

[0006] The mountain guard has a main body and a second needle running part below the main body in a direction parallel to the bottom plate of the flat knitting machine. The lower edge of the main body constitutes the first needle running surface, and the lower edge of the second needle running part constitutes the second needle running surface.

[0007] The middle guard has a higher first needle running part and a lower second needle running part in a direction perpendicular to the bottom plate of the flat knitting machine. The interface formed by the first needle running part being higher than the second needle running part is the first needle running surface, and the lower edge of the second needle running part constitutes the second needle running surface.

[0008] The press needle triangle is fixedly connected to the press needle connecting block, which has a guide and a roller. A first long groove is provided on the base plate, and the guide cooperates with the first long groove; it also includes a press needle push rod, which has a rack and can be driven by a gear to translate relative to the base plate; a second long groove is provided on the press needle push rod, which cooperates with the roller of the press needle connecting block; the first long groove and the second long groove form a certain angle.

[0009] Through the above-mentioned improvement of the bottom plate, the flat knitting machine can complete the lining warp weaving, add warp knitting structure to the fabric, enrich the pattern, and increase the strength of the cloth. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See the attached drawings. The bottom plate 1 of the flat knitting machine in this embodiment is symmetrical on both sides. There are guardrails 4 and 31 on both sides of the top. The inner sides of the guardrails are press cams 3 and 30. There is a return cam 6 under the guardrails. Since the bottom plate is symmetrical on both sides, only one side is introduced below. Figure 7 Read in comparison.

[0020] The mountain guard 4 has a main body 40 and a second needle running part 41 below the main body in a direction parallel to the bottom plate of the flat knitting machine. The lower edge of the main body constitutes a first needle running surface 401, and the lower edge of the second needle running part constitutes a second needle running surface 411.

[0021] The middle guard 7 has a higher first needle running part 71 and a lower second needle running part 72 in the direction perpendicular to the bottom plate of the flat knitting machine. The interface 711 formed by the first needle running part being higher than the second needle running part is the first needle running surface, and the lower edge of the second needle running part constitutes the second needle running surface 721.

[0022] The press needle cam 3 is fixedly connected to the press needle connecting block 19, which has a guide (not shown in the figure) and a roller 20. A first long groove 101 is provided on the base plate, and the guide cooperates with the first long groove; it also includes a press needle push rod 17, which has a rack 16 and can be driven by a gear to translate relative to the base plate and the press needle push rod seat 18; a second long groove 171 is provided on the press needle push rod, which cooperates with the roller 20 of the press needle connecting block; the first long groove and the second long groove form an angle of 90°.

[0023] The knitting process of this embodiment is as follows:

[0024] When walking the tight tuck route 22, the right receiving needle presser leg retreats, the left receiving needle presser leg and the tuck presser leg enter. After the needle selection result of the previous route, some spring needles enter the H position, and some knitting needles enter the Zhongshan guide block needle track. Since the right receiving needle presser leg is in the exit state, the knitting needle runs in the Zhongshan guide block track. When the spring needle scratches the tuck presser leg, since the presser leg is in the entry state, the spring needle is squeezed by the tuck presser leg, and the knitting needle exits the track, crosses the Zhongshan guide block, and then enters the Zhongshan guide block track. Finally, under the squeezing of the left receiving needle presser leg, it passes through the mesh triangle surface, does not go down along the mesh triangle, and enters the left needle track of the mountain guard, ensuring the position height of the knitting needle warp lining, and scratches out the bottom plate to complete the warp lining action.

[0025] When taking the tight knitting route 23, the tight knitting press leg enters on the left, and a part of the spring needles enter the A position under the action of the needle push triangle, and a part of the knitting needles enter the needle track of the Zhongshan guide block. Since the right needle press leg is in the exit state, the knitting needle runs in the Zhongshan guide block track. When the spring needle is scratched to the left of the tight knitting press leg, since the press leg is in the entry state, the spring needle is squeezed by the left of the tight knitting press leg, so that the knitting needle passes through the mesh triangle surface and does not go down along the mesh triangle. It enters the needle track of the left mountain guard, ensuring the position height of the knitting needle warp lining, and scratching out the bottom plate to complete the warp lining action.

[0026] After completing the warp inserting action, the machine head runs in the reverse direction. At this time, the knitting needle needs to be guided by the lower end of the middle guard to prevent the needle from colliding with the guard and causing damage to the fabric.
