Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings.

Referring to fig. 1, an adjustable needle return cam comprises a needle return cam 1 and an adjusting slide block 2, wherein the needle return cam 1 is slidably arranged on a cam 3, and the adjusting slide block 2 is slidably arranged between the needle return cam 1 and the cam 3.

Referring to fig. 2 and 3 again, a limit slider 31 is fixedly arranged on the cam plate 3, a sliding groove 11 in sliding fit with the limit slider 31 is formed in the middle of the clip cam 1, a connecting hole 33 penetrating through the limit slider 31 from front to back is formed in the middle of the limit slider 31, the cam plate 3 is provided with a through hole communicated with the connecting hole 33, the limit slider 2 and the cam plate 3 are fixed by penetrating through the connecting hole 33 and the through hole through a connecting piece, the connecting piece of the embodiment preferably adopts a screw, the limit slider 31 is locked to prevent the clip cam 1 from shaking to influence the stability of a knitting needle, and when the height position of the clip cam 1 needs to be adjusted, the connecting piece is loosened to enable the clip cam 1 to freely slide up and down to adjust the height position.

And fixed fixing base 4 that is provided with on the gable 3, first bar groove 41 has on the fixing base 4, the one end of adjusting block 2 is provided with first smooth axle 22 with first bar groove 41 sliding fit, the other end of adjusting block 2 has second bar groove 23, be provided with on the gable 3 with second smooth axle 32 with second bar groove 23 sliding fit, make adjusting block 2 can remain the level throughout at the slip in-process through first, second bar groove, avoid appearing the error.

The upper portion of the back stitch triangle 1 has the insertion shaft 12, the middle part of the adjusting slide block 12 has the chute 21 which is in sliding fit with the insertion shaft 12, when the height of the back stitch triangle 1 needs to be adjusted, through loosening the connecting piece, slide right when pushing the adjusting slide block 2, then the insertion shaft 12 links the back stitch triangle 1 to slide downwards along the limiting slide block 31 under the action of the chute 21, slide leftwards when pushing the adjusting slide block 2, then the insertion shaft 12 links the back stitch triangle 1 to slide upwards along the limiting slide block 31 under the action of the chute 21, thereby realizing the height adjustment of the back stitch triangle 1, the height adjustment is not needed to be carried out through the dismounting mode, and the working efficiency of the flat knitting machine is greatly improved.

Referring to fig. 1, a first knitting unit and a second knitting unit are symmetrically arranged in a cam 3 of the present application, a needle return cam 1 is arranged on two sides of the first knitting unit and the second knitting unit, the first knitting unit and the second knitting unit include a herringbone cam, a stitch transferring cam, a knitting cam, a first stitch cam and a second stitch cam, and the herringbone cam, the stitch transferring cam, the knitting cam, the first stitch cam and the second stitch cam in the present embodiment are known technologies, and are not repeated herein.

In this embodiment, the knitting needle return cam 1 is of a diamond structure, and a cam protector is respectively disposed under the knitting needle return cam 1, the cam protector in this embodiment is a known technology, and will not be described herein repeatedly, a needle track is formed between each of the knitting needle return cams 1 and the cam protector for controlling a knitting needle to ascend or descend, when the knitting needle reaches the needle track after passing through the first knitting unit, one of the inclined planes of the knitting needle return cam 1 blocks a butt of the knitting needle, so that the knitting needle moves to the other inclined plane along the bottom edge of the knitting needle return cam 1, thereby effectively preventing the knitting needle from directly punching out of the knitting needle return cam 1, and avoiding the knitting quality of the fabric from being affected by the knitting needle due to needle crossing, needle missing, and the like. And traditional back stitch triangle is the triangle-shaped structure, and traditional back stitch triangle slope sets up for the knitting needle is easy directly to be washed out along its upper edge when reaching back stitch triangle, leads to the knitting needle to appear the condition such as cluster needle, miss stitch, greatly reduced the knitting quality of fabric.

Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention, and all modifications made according to the spirit of the main technical solution of the present invention should be covered within the protection scope of the present invention.
