[0034] The present embodiment provides a linkage control structure of a base plate control cam for tightening the tuck, comprising a base plate 1 and a plurality of knitting areas arranged side by side on the base plate 1; each knitting area comprises a needle guide cam 2 and a needle transfer cam 3, and a control cam 4 slidably arranged between the two for controlling the tightness of the tuck in the knitting area; a linkage drive device 5 for synchronously driving the control cam 4 to slide is also provided on the back side of the base plate 1. A plurality of knitting areas arranged side by side are arranged on the bottom plate, including a first knitting area 101, a second knitting area 102 and a third knitting area 103, so that knitted fabrics with the same tuck tightness can be knitted in the width direction of the fabric during the knitting process. The tuck tightness is adjusted by setting a control triangle 4 between the guide needle three 2 and the needle transfer triangle 3. The height between the upper and lower guide needle end surfaces of the control triangle 4 and the guide needle triangle 2 and the needle transfer triangle 3 is adjusted to achieve the adjustment of the tuck tightness. A linkage drive device 5 is set on the back side of the bottom plate 1 to synchronously drive the corresponding control triangle 4 on each knitting area to achieve the tuck tightness of the same knitting position of the knitted fabric and ensure the structural consistency of the knitted fabric.

[0035] In a specific embodiment of the present case, the sliding direction of the control cam 4 is arranged parallel to the guide needle slope 31 of the transfer cam 3, and the guide needle cam 2 and the transfer cam 3 are respectively provided with sliding guide slopes that fit with the guide needle surfaces on both sides of the control cam 4. During the knitting process, the upper and lower surfaces of the guide needle cam 2 and the transfer cam 3 are in contact with the knitting needles. In order to avoid the sliding action of the control cam 4 between the two and cause the stitch to fall off, it is necessary to stabilize the transition between the guide surfaces of the guide needle cam 2 and the transfer cam 3 during the sliding process of the control cam 4.

[0036] The sliding direction of the control triangle 4 is arranged parallel to the guide bevel 31 of the needle turning triangle 3, the first guide bevel on the side of the control triangle 4 opposite to the guide needle triangle 2 is arranged parallel to the guide needle bevel 31 of the needle turning triangle 3, the guide bevel 31 of the needle turning triangle 3 in contact with the control triangle 4 is opened as a sink structure 32, the back side of the control triangle 4 is opened as a half groove structure 41 which is buckled and slidably matched with the sink structure 32, and the second guide bevel on the side in contact with the needle turning triangle 3 is in sliding contact with the inner wall of the sink structure 32, which plays a sliding guide and limiting function, thereby improving the sliding stability of the control triangle 4.

[0037] In a specific embodiment of the present case, each control cam 4 has a driving rod 42 extending from the back side of the bottom plate; the linkage driving device 5 includes a pushing slider 54 that cooperates with each control cam 4 to push it to slide, and the pushing slider 54 is provided with a protruding end for accommodating the driving rod 42 and a pushing slide 541 that is press-fitted with both sides of the driving rod 42 in two sliding directions. The front side of the bottom plate 1 is a knitting plane, and the sliding driving structure is set by using the space on the back side of the bottom plate 1 to control the sliding of the control cam 4 in the thickness direction of the bottom plate 1.

[0038] Each control triangle 4 has the same structure to achieve the same tuck tightness control on the bottom plate 1. Specifically, taking the structure of one of the control triangles 4 as an example, a driving rod 42 extends from the back side of the control triangle 4, and the linkage driving device 5 is attached to the back side of the bottom plate 1 by a pushing slider 54. The pushing slider 54 is provided with a strip-shaped pushing chute 541, and the protruding end of the driving rod 42 falls into the pushing chute 541. The two side walls in the width direction of the pushing chute 541 abut against the radial outer peripheral surface of the driving rod 42 to drag the control triangle 4 to slide.

[0039] Specifically, since the base plate 1 is a plate structure with a certain thickness, and at the same time, in order to avoid the instability of only the guide and limiting structure on the control triangle 4 and the needle turning triangle 3, a guide slider 43 is integrally fixed on the back side of the control triangle, a guide groove is opened on the base plate 1, and the driving rod 42 extends out of the back side of the guide slider 43. The sliding of the guide slider 43 in the guide groove on the base plate 1 further ensures the stability of the sliding action of the control triangle 4.

[0040] In a specific embodiment of the present case, the control cam 4 includes a first control cam 401 and a second control cam 402 symmetrically arranged on both sides of the transfer cam, and the first control cam 401 and the second control cam 402 act synchronously. Adapting to the symmetrical arrangement structure of the transfer cam 3 and the guide cam 2 on the bottom plate 1, the control cam 4 is set to be the first control cam 401 and the second control cam 402 symmetrically arranged on both sides of the transfer cam 3, so as to realize the output of knitted fabrics with different patterns on both sides of the same knitting area.

[0041] In a specific embodiment of the present case, the linkage drive device 5 also includes a pull rod 53 arranged at the top of the back side of the base plate, which synchronously pulls each pushing slider 54 to translate along the length direction of the base plate 1; the pushing slide groove 541 opened on the pushing slider 54 adopts a different inclination arrangement in the sliding direction of the corresponding control triangle 4; and also includes a power device 51 that drags the pull rod 53 to slide horizontally.

[0042] The first control triangle 401 and the second control triangle 402 are arranged with respect to the needle turning triangle 4, and the pushing slider 54 is correspondingly provided with the first pushing slider and the second pushing slider, which respectively drag the position adjustment of the first control triangle 401 and the second control triangle 402, so as to meet the adjustment of the different tightness of the tucks on both sides of the needle turning triangle 3.

[0043] The linkage driving device 5 is moved by dragging each pushing slider 54 by the pull rod 53. The first pushing slider and the second pushing slider of each pushing slider 54 are connected to the pull rod 53 at the same time, that is, each pushing slider 54 is respectively connected to the pull rod 53 in the pull rod length direction. During the translation of the pull rod 53 along the plate surface of the base plate 1, the first pushing slider and the second pushing slider corresponding to each pushing slider 54 are dragged to slide at the same time. The driving structure is simple and can achieve the same tightness control.

[0044] In a specific embodiment of the present case, the power device 51 includes a driving motor 511 and a driving gear 512 arranged at the output end of the driving motor; a gear rack transmission device 52 for dragging the pull rod 53 is mounted between the driving gear 512 and the pull rod 53; the gear rack transmission device 52 includes a drag gear 521 and a drag rack 522, and a drag rod 523 connected to the pull rod 53 extends from the drag rack 522. The gear transmission structure is arranged between the driving motor 511 and the pull rod 53 to improve the compactness of the structure.

[0045] The pull rod 53 is connected to the drag rod 523, and the extended end of the drag rod 523 adopts a drag rack 522 and a drag gear 521 to realize the translational drag of the pull rod 53 on the surface of the bottom plate 1. The power device 51 is provided with a drag power by a driving motor 511, and a driving gear 512 is arranged at its output end, which meshes with the drag gear 521 of the gear rack transmission device 52, and the power output is stable, ensuring the stability of the control triangle sliding.

[0046] Specifically, the drag gear 521 includes a first sector gear area 5211 meshing with the driving gear 512, and a second sector gear area 5212 meshing with the drag rack 522; the inner diameter of the first sector gear area 5211 is greater than the inner diameter of the second sector gear area 5212, and the rotation axis of the drag gear 521 is located in the second sector gear area 5212. The drag gear 521 uses a special-shaped gear composed of a first sector gear area 5211 and a second sector gear area 5212 with different inner diameters. The first sector gear area 5211 meshes with the driving gear 512, and the second sector gear area 5212 meshes with the drag rack 522. The purpose of speed change is achieved by having two sector gear areas with different inner diameters, and stable output power is output, further ensuring the stability of the control triangle adjustment.

[0047] A mounting frame 7 for mounting the base plate 1 is disposed on the back side thereof, and the rack and pinion transmission device 52 is mounted on the mounting frame 7 .

[0048] In a specific embodiment of the present case, the back side of the bottom plate 1 is also provided with a protective plate 6 mounted on one side of the push slider in the thickness direction to guide and protect its horizontal sliding. The push slider 54 slides in the back plane of the bottom plate 1. Since the push slider 54 and the control triangle 4 adopt a pressing and pushing structure with abutment, in order to avoid the control triangle 4 from getting stuck during the sliding process, a protective plate 6 is provided on the bottom plate 1 and attached to one side of the push slider 54 in the thickness direction. The protective plate 6 and the bottom plate 1 form a sliding channel for the push slider 54, providing sliding protection for the push slider and improving the sliding safety of the push slider.
