Description

Technical Field

[0001] This invention relates to the field of flat knitting machines, and more particularly to a base plate, needle assembly, and knitting method for a flat knitting machine. Background Technology

[0002] In traditional flat knitting machines, the triangular base plate structure often has some limitations. Its longitudinal width and needle plate width are relatively large, which not only occupies a significant amount of space but also contributes to the overall bulky structure of the flat knitting machine, hindering miniaturization and compact design. Commonly used needle plates typically employ spring-loaded needle feet in conjunction with needle selector plates to perform station switching and needle selection functions. This approach is not optimal for implementing multiple functions, and it also has limitations in needle selection stability and functional implementation, restricting the diversity of knitting patterns and improving production efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a base plate, needle assembly, and knitting method for a horizontal knitting machine.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A base plate and needle assembly for a flat knitting machine include a base plate on which knitting zone assembly and station needle selection zone assembly are mounted sequentially. The base plate also includes a needle assembly comprising knitting needles, long needles, and station needle selection needles that cooperate with each other. The long needles contact and cooperate with the knitting zone assembly and drive the knitting needles to move. The station needle selection needles contact and cooperate with the station needle selection zone assembly and drive the knitting needles to move. Through the above cooperation, station switching and needle selection / pre-selection functions are completed, and different knitting methods are completed in cooperation with the long needles and knitting needles.

[0006] Preferably, the knitting area component includes a herringbone triangle, a needle path switching triangle, and a knitting triangle arranged vertically, and also includes two gauge triangles located on the left and right sides. The herringbone triangle, needle path switching triangle, knitting triangle, and gauge triangle constitute a knitting unit. Two knitting units are installed on the base plate. Between the knitting units, there are also a middle guard and a middle retention triangle arranged vertically and fixed to the base plate. The left side of the left knitting unit has a left guard and a left retention triangle arranged vertically and fixed to the base plate. The right side of the right knitting unit has a right guard and a right retention triangle arranged vertically and fixed to the base plate.

[0007] Preferably, the system also includes a needle selector mounted on the base plate. The needle selector is located on the left and right sides below the needle selection area assembly of each knitting unit. A needle selection guard is also mounted on the base plate above the needle selector. The needle selector at the work station is provided with a needle heel. The end face of the needle heel is provided with a hook groove. The hook groove cooperates with the protrusion on the needle selection guard. When the needle selector at the work station moves along a specific triangular contour to the needle selection area, the needle heel is hung on the needle selection guard through the hook groove, so that the needle selector at the work station that does not need to participate in knitting is limited to a suitable position.

[0008] Preferably, the needle guards are fixedly mounted on the left retention triangle, right retention triangle and middle retention triangle and integrally formed with them.

[0009] Preferably, the tail of the knitting needle is provided with a rotating groove, the head of the long needle engages with the rotating groove and can rotate up and down with the front end of the groove as the center. The middle of the long needle has an upwardly protruding needle heel that engages with the knitting zone assembly. The tail of the long needle contacts the bottom of the needle groove of the frame. The long needle is an elastic needle. The head of the station needle selector is mounted on the upper surface of the tail of the long needle. The needle selector heel is located at the head of the station needle selector and protrudes upward. The station needle selector is positioned by a limiting wire to prevent it from loosening. The middle of the station needle selector has a needle selector heel that engages with the needle selector. When the needle selector heel is pressed down, due to the elastic effect, the long needle is also pressed into the needle groove, and the needle heel of the long needle cannot contact the knitting zone assembly.

[0010] Preferably, the needle selection area assembly includes a left needle receiving plate, a hanging eyelet plate, and a right needle receiving plate located in the middle of the base plate and below the knitting unit. A non-woven pressure plate is also installed below the left needle receiving plate, the hanging eyelet plate, and the right needle receiving plate. The left needle receiving plate, the hanging eyelet plate, the right needle receiving plate, and the non-woven pressure plate are all provided with arc-shaped positioning grooves, and the upper end of the needle selection heel is provided with an arc-shaped protrusion that cooperates with the arc-shaped positioning groove.

The corresponding long needle heel also sinks into the needle groove. The long needle heel does not contact the triangle outline. The knitting needle stays at the lifting eye height. The triangle base plate performs the lifting eye function.

[0015] 3) Perform the knitting function: The needle path switching triangle, left needle presser plate, and right needle presser plate sink into the base plate. The needle selector blade is raised and does not contact the station needle selector. The selected station needle contacts the left retaining triangle and the left needle selector triangle and pushes the station needle selector upward to the position. After another needle selection, the selected station needle selector moves further upward along the outline of the left pusher triangle to the position. The station needle selector continues to move to the right without contacting the presser plates (left needle presser plate, hanging eyelet presser plate, right needle presser plate, and non-woven presser plate). The heel of the long needle always protrudes from the needle groove and moves along the shape of the knitting triangle to push the knitting needle to the knitting height. The triangle base plate performs the knitting function.

[0016] 4) Perform the needle flipping function: The left and right needle press plates sink into the base plate, the needle selector blade is raised and does not contact the needle selector boss, the selected needle at the work station contacts the left retaining triangle and the left needle selector triangle and pushes the work station needle to move up to the position, and then passes through the needle selection again. The selected needle at the work station moves further up to the position along the outline of the left push needle triangle. The work station needle continues to move to the right without contacting the press plates (left needle press plate, hanging eyelet press plate, right needle press plate and non-woven press plate). The heel of the long needle always protrudes from the needle groove and moves along the shape of the knitting triangle to pass through the needle path switching triangle and enter the needle flipping needle path. The long needle pushes the knitting needle to complete the needle flipping function.

[0017] 5) Perform the right needle connection function: The hanging eye pressure plate, the right needle connection pressure plate, the left push needle triangle and the right push needle triangle sink into the base plate. The triangle base plate moves to the left. The needle selector blade is raised and does not contact the needle selection boss. The selected needle at the work station contacts the left retaining triangle and the left needle selection triangle and pushes the work station needle selection upward. The work station needle selection continues to move to the right. The left needle connection pressure plate presses the needle heel of the needle selection into the needle groove. The work station needle selector touches the long needle bar and presses the long needle heel into the needle groove as well. The long needle heel does not contact the outer contour of the knitting triangle. The long needle continues to move to the right until it reaches the hanging eye pressure plate position that sinks into the base plate. The long needle heel protrudes from the needle groove and contacts the knitting triangle needle connection contour, pushing the knitting needle into the needle connection needle path, so that the knitting needle completes the right needle connection function.

[0018] 6) Perform the left needle connection function: The hanging eye pressure plate, left needle connection pressure plate, left push needle triangle and right push needle triangle sink into the base plate. The triangle base plate moves to the right. The needle selector blade is raised and does not contact the needle selection boss.

The long needle heel protrudes from the needle groove and contacts the knitting triangle needle connection contour, pushing the knitting needle into the needle connection needle path, so that the knitting needle completes the left needle connection function.

[0019] 7) Perform the flip function: The hanging needle pressure plate and the right needle receiving pressure plate sink into the bottom plate. The needle selector blade is raised and does not contact the needle selection boss. The selected needle at the work station contacts the left retaining triangle and the left needle selection triangle and pushes the work station needle to move up to the position. After another needle selection, the selected needle at the work station moves up further along the outline of the left push needle triangle to the position. The long needle pushes the knitting needle into the flip needle path. At this time, the second unselected needle at the work station stays at the first upward movement height and is in the position. The long needle pushes the corresponding knitting needle into the receiving needle path. The above functions are the flip functions performed in the same knitting instruction of the same system.

[0020] 8) Performing the same-line hanging needle tape weaving function: The needle path switching triangle, the left needle pressing plate, and the right needle pressing plate sink into the base plate. The needle selector blade is raised and does not contact the station needle selection. The selected station needle contacts the left retaining triangle and the left needle selection triangle and pushes the station needle up to the position. After another needle selection, the selected station needle moves further up to the position along the outline of the left push needle triangle. The long needle pushes the knitting needle into the weaving needle path. At this time, the second unselected station needle stays at the original height and is in position.
