Combined needle mechanism of flat knitting machine

Abstract

The utility model relates to a combined needle mechanism of a flat knitting machine, which comprises a needle bed and a plurality of insertion sheets, a needle groove is formed among the insertion sheets, a knitting needle, a tall needle, a fork needle and a selection needle are sequentially arranged in the needle groove, and the knitting needle, the tall needle, the fork needle and the selection needle are mutually connected. The needle is characterized in that an upper butt and a lower butt are integrally formed on the tall needle, a butt is integrally formed on the fork needle, and the lower butt and the butt are limited in the needle groove. When the high needle lower butt and the fork needle butt of the combined needle mechanism of the flat knitting machine do not work, the high needle lower butt and the fork needle butt are prevented from making contact with a triangular plate in the moving process of a machine head, and therefore friction force borne by the machine head in the moving process is reduced; and therefore, the working efficiency is improved, the service lives of the machine head triangle and the needle are prolonged, and the noise during operation is reduced.

Description

Technical Field

[0001] This application relates to a combined needle mechanism for a flat knitting machine, belonging to the technical field of flat knitting machines. Background Art

[0002] The combined needle consists of a knitting needle, a high-leg needle, a latch needle, and a selector needle. When the flat knitting machine is performing knitting work, etc., the knitting needle makes regular lifting and lowering movements in the needle groove of the insert piece, and through the actions of the needle hook and the needle tongue, the yarn can be knitted into a knitted fabric.

[0003] In the existing structure, the high-leg needle and the latch needle are as Figure 1 described. Part of the high-leg needle 3' and the latch needle 4' are exposed outside the needle groove, resulting in the contact between the triangular bottom plate and the high-leg needle 3' and the latch needle 4' during the movement process, increasing the friction force and reducing the production efficiency.

[0004] Therefore, to solve the above technical problems, it is indeed necessary to provide a combined needle mechanism for a flat knitting machine to overcome the defects in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a combined needle mechanism that can reduce the friction with the triangular plate.

[0006] To achieve the above purpose, the technical solution adopted by this utility model is: A combined needle mechanism for a flat knitting machine includes a needle bed and a number of insert pieces. Needle grooves are formed between the insert pieces. A knitting needle, a high-leg needle, a latch needle, and a selector needle are sequentially arranged in the needle grooves. The knitting needle, the high-leg needle, the latch needle, and the selector needle are connected to each other. An upper needle bell and a lower needle bell are integrally formed on the high-leg needle, and a needle bell is integrally formed on the latch needle. The lower needle bell and the needle bell are restricted within the needle groove. By adopting the above technical solution, during the movement of the triangular plate, it will not contact the lower needle bell of the high-leg needle and the needle bell of the latch needle when they are not working, thereby reducing the friction force received during the movement of the triangular plate, and thus improving the efficiency.

[0007] The combined needle mechanism for a flat knitting machine of this utility model is further provided as: It further includes a first steel bar and a second steel bar. The first steel bar and the second steel bar pass through the insert pieces. When the lower needle bell and the needle bell sink into the needle groove, the first steel bar abuts against the top surface of the high-leg needle, and the second steel bar fits against the top surface of the latch needle.

[0008] The combined needle mechanism for a flat knitting machine of this utility model is further provided as: When the lower needle bell and the needle bell sink into the needle groove, the first steel bar abuts against the side wall of the lower needle bell, and the second steel bar abuts against the side wall of the needle bell.

[0009] The combined needle mechanism for a flat knitting machine of this utility model is further provided as: It further includes a third steel bar. A number of limiting grooves are formed on the latch needle, and the limiting grooves cooperate with the third steel bar.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, the positions of the high-foot needles and the fork needles are such that during the movement of the triangular plate, it will not contact the lower needle clock of the high-foot needle and the needle clock of the fork needle when they are not working, thereby reducing the friction force received during the movement of the triangular plate, improving the efficiency, increasing the service life of the needles and the triangle, and reducing the noise in the working state. Description of the Drawings

[0013] Figure 2 is a schematic diagram of the lower needle clock and the needle clock of the combined needle mechanism of the flat knitting machine of the utility model exposed outside the needle groove;

[0014] Figure 3 is a schematic diagram of the lower needle clock and the needle clock of the combined needle mechanism of the flat knitting machine of the utility model sunk into the needle groove. Detailed Embodiment

[0015] Please refer to the attached drawings of the specification Figure 1 to Figure 3 As shown, the utility model is a combined needle mechanism of a flat knitting machine, including a needle bed 8 and a plurality of inserts 1. Needle grooves are formed between the plurality of inserts 1. A knitting needle 2, a high-foot needle 3, a fork needle 4, and a needle selector 5 are sequentially arranged in the needle grooves. The knitting needle 2 and the high-foot needle 3 are connected to each other. The fork needle 4 and the needle selector 5 cooperate with each other. An upper needle clock 31 and a lower needle clock 32 are integrally formed on the high-foot needle 3. A needle clock 41 is integrally formed on the fork needle 4. When not in use, the lower needle clock 32 and the needle clock 41 sink into the needle grooves. A first steel bar 6 and a second steel bar 7 pass through the inserts 1; when the lower needle clock 32 and the needle clock 41 sink into the needle grooves, the first steel bar 6 abuts against the top surface of the high-foot needle 3, the second steel bar 7 fits against the top surface of the fork needle 4, the first steel bar 6 abuts against the side wall of the lower needle clock 32, and the second steel bar 7 abuts against the side wall of the needle clock 41; a plurality of limit grooves are formed on the fork needle 4. The plurality of limit grooves are sequentially an A position 401, an H position 402, and a B position 403. The limit grooves cooperate with a third steel bar 9 to limit the moving position of the fork needle 4. When the triangular plate moves in the a direction (taking the figure as an example) and drives the fork needle 4 to move downward, the third steel bar 9 abuts against the A position 401, the H position 402, and the B position 403 in sequence. When the third steel bar 9 is located at the A position 401, the lower needle clock 32 and the needle clock 41 sink into the needle grooves and do not bounce up. When the third steel bar 9 is located at the H position 402 and the B position 403, the lower needle clock 32 and the needle clock 41 are exposed outside the needle grooves. When the third steel bar 9 is located at the H position 402, if the fork needle 4 wants to exit the hidden state, only need to use a jacquard needle to push the insert needle into the H position 402. During the movement of the triangular plate when the third steel bar 9 is located at the A position 401, it will not contact the lower needle clock 32 and the upper needle clock 31, reducing the friction force received during the movement of the triangular plate, thereby improving the efficiency.

[0016] The above specific embodiments are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
