Description

TECHNICAL FIELD

[0001] The present application relates to the field of flat knitting machines, in particular to a flat knitting machine combined needle and needle plate limiting structure. BACKGROUND

[0002] A computer flat knitting machine is a double needle plate weft knitting machine. The knitting is completed by the combined needle in the needle slot on the needle plate moving up and down along the needle slot under the cooperation of the cam mechanism and the pulling mechanism during the reciprocating movement of the cam mechanism on the head along the guide rail.

[0003] The combined needle includes a knitting needle with a needle hook, a long needle (also known as a high needle), a spring needle (also known as a fork needle), and a selection needle, as shown in CN222990338U.

[0004] Therefore, the knitting principle of the flat knitting machine determines that when the knitting needle does not participate in the work, it cannot be driven by other components or the vibration of the flat knitting machine itself to move upward. However, as the requirements for knitting increase, the layout of the knitting needles of the flat knitting machine becomes more and more compact, and there is a possibility of mutual interference or friction between adjacent knitting needles. The possibility of the knitting needle not participating in knitting being driven by external force increases.

[0005] Therefore, the present inventors have further researched and developed a flat knitting machine combined needle and needle plate limiting structure, which has thus been produced. SUMMARY

[0006] The purpose of the present application is to provide a flat knitting machine combined needle and needle plate limiting structure that can prevent knitting needles that do not participate in knitting from moving towards the needle opening of the needle plate.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present application is as follows: A flat knitting machine combined needle and needle plate limiting structure, comprising a needle plate, the needle plate is provided with a plurality of combined needles, the combined needle comprises a knitting needle, a long needle and a spring needle arranged in sequence, wherein the long needle is provided with a first limiting portion on the side facing the needle plate, and the needle plate is provided with a second limiting portion corresponding to the first limiting portion, when the spring needle presses down the long needle, the second limiting portion limits the first limiting portion, so that the knitting needle does not move towards the needle opening of the needle plate.

[0008] The needle opening of the needle plate refers to the space where the knitting needle participates in hooking the yarn, that is, the highest point of the two inclined needle plates; the arrangement relationship between the knitting needle, the long needle, the spring needle and the selection needle is a common knowledge in the art. Therefore, when the first limiting portion of the long needle and the second limiting portion of the needle plate interact to prevent the long needle from moving towards the needle opening, the knitting needle cannot move towards the needle opening.

[0009] Furthermore, both the first and second limiting parts are protruding structures. When the spring needle presses down on the long needle, the second limiting part is closer to the needle plate and needle mouth position than the first limiting part.

[0010] When both the first limiting part and the second limiting part are protruding structures, the second limiting part is relatively higher and can suppress the first limiting part from moving upward, thereby restricting the needle from moving upward.

[0011] Furthermore, the first limiting part is a protruding structure, and the second limiting part can accommodate the first limiting part.

[0012] Furthermore, the first limiting part and the second limiting part correspond to the heel of the spring needle.

[0013] When the needle is not selected by the needle selector, the heel of the spring needle is pressed by the non-knitting triangle on the triangle base plate, which in turn presses down the long needle and prevents the needle from entering the knitting action.

[0014] Furthermore, the needle plate surfaces on both sides of the second limiting part are relatively concave, and the highest point of the second limiting part is consistent with the surface of the entire needle plate.

[0015] By adopting the above solution, the present invention has the following advantages compared with the prior art: The pressing action of the spring needle when the needles in this combination are not involved in knitting causes the first limiting part of the long needle and the second limiting part of the needle plate to interact with each other, thereby restricting the movement of the knitting needle towards the needle opening and ensuring that the knitting needle will not be driven by external force when it is not involved in knitting.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] A flat knitting machine combination needle and needle plate limiting structure includes combination needles and a needle plate 5. The needle plate has several inserts, and the combination needles are positioned between these inserts, so that the combination needles are positioned relative to each other on the needle plate. After the needle selector 7 of the triangular base plate 6 selects the combination needles, it can be determined whether the needle 1 participates in the knitting work or not. Since this embodiment mainly focuses on improvements when the combination needles do not participate in the knitting work, the state of the combination needles participating in the knitting work will not be described further.

[0020] Specifically, with Figure 1 , Figure 2 Taking the angle as an example, the combination needle includes knitting needle 1, long needle 2, spring needle 3, and selector needle 4 from top to bottom. The long needle 2 is provided with a first limiting part 21 on the side facing the needle plate, and the needle plate is provided with a second limiting part 51 at the corresponding position. The needle plate surfaces on both sides of the second limiting part 51 are relatively concave.

[0021] The first limiting part 21 corresponds to the needle heel 31 at the end of the spring needle 3. That is, when the selected needle 4 is not selected by the needle selector 4, the needle heel at the end of the spring needle 3 is pressed by the non-knitted triangle on the triangle base plate. Since the long needle 2 has a certain deformation capability, the first limiting part 21 will move towards the needle plate, such as... Figure 2 , Figure 3 As shown, in this embodiment, the first limiting part 21 and the second limiting part 51 adopt a protruding structure with a triangular cross-section. At this time, the second limiting part 51 is positioned above the first limiting part 21, meaning the needle plate can prevent the long needle 2, which is in a non-knitting state, from continuing to move upwards. The knitting needle 1 is restricted by the long needle 2, therefore the knitting needle 1 will not be subjected to external force towards the needle opening (in...). Figure 1 , 2 (The middle part is the top position of the needle plate) movement.

[0022] Figure 4 This diagram only shows the correspondence between the combined needle and the triangular base plate. In reality, in a flat knitting machine, the needle plate is fixed on the needle bed, and the triangular base plate is moved back and forth on the surface of the needle plate by the machine head. The positional relationship shown in the diagram is not as shown.

[0023] The above are merely specific embodiments of the present invention. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in the present invention are for reference only in relation to the accompanying drawings and are not absolute limitations. Any non-substantial modifications made using the present invention shall be considered as infringing upon the protection scope of the present invention.
