Detailed Description
In order to further explain the technical scheme of the utility model, the utility model is explained in detail by specific examples.
As shown in fig. 1 to 3, the utility model discloses a jacquard structure of a knitting machine, which comprises a knitting needle 1, a knitting needle cam 2, an intermediate needle 3, an intermediate needle cam 4, a reset cam 5, a jacquard sheet 6, a needle selector 7 and a needle cylinder 8, wherein the knitting needle 1 is provided with a knitting needle butt 13, the knitting needle cam 2 is connected with the knitting needle butt 13, the intermediate needle 3 is provided with an intermediate needle butt 32, the intermediate needle cam 4 is connected with the intermediate needle butt 32, the jacquard sheet 6 is provided with a reset butt 62 and a needle selector butt 63, the reset cam 5 is connected with the reset butt 62, the needle selector 7 is arranged corresponding to the needle selector butt 63 of the jacquard sheet 6, the outer side of the needle cylinder 8 is milled with a groove, and the jacquard sheet 6 and the intermediate needle 3 are inlaid in the groove of the needle cylinder 8.
The knitting needle 1 comprises a needle head 11, a needle tongue 12, a knitting needle butt 13 and a knitting needle tail 14, the needle head 11 and the knitting needle tail 14 are correspondingly arranged at the front end and the rear end of the knitting needle 1, the needle tongue 12 is rotatably arranged behind the needle head 11, and the knitting needle butt 13 is arranged between the needle tongue 12 and the knitting needle tail 14. Wherein, the width range of the needle head is 1.00 mm-1.50 mm, the range of the needle tongue stroke is 7.50 mm-10.50 mm, the working length range is 64.50 mm-67.50 mm, the range of the needle tail height is 2.00 mm-4.00 mm, and the width of the needle head refers to the outer side dimension of the needle head position of the knitting needle; the needle tongue stroke refers to the farthest horizontal distance between the needle head and the needle tongue; the working length refers to the distance from the needle head to the butt; the tail height refers to the width of the tail of the knitting needle; the thickness of the knitting needle is the thickness of the pointer body.
The middle needle 3 comprises a hook 31, a middle butt 32 and a middle needle tail 33, the hook 31 of the middle needle 3 is arranged at the front end of the middle needle 3, and the knitting needle 1 is provided with a clamping groove 15 for connecting the hook 31 of the middle needle 3. A groove 34 correspondingly matched with the knitting needle tail 14 is arranged between the clamping hook 31 of the intermediate needle 3 and the intermediate needle butt 32.
The jacquard 6 is provided with a connecting part 61 connected with the middle needle 3, the middle needle tail 33 is connected with the connecting part 61 of the jacquard 6, in this embodiment, the connecting part 61 is an elastic open groove, and the middle needle tail 33 is inserted into the elastic open groove, so that the elastic open groove clamps the middle needle tail 33.
The needle cylinder 8 is a circular workpiece, grooves are milled on the outer side, and the jacquard sheet 6 and the middle needle 3 are inlaid in the grooves, so that normal movement is limited. When the needle selector 7 acts, the jacquard sheet 6 with the middle needle 3 is pushed to the depth of the groove on the needle cylinder 8, so that the middle needle 3 is separated from the knitting needle 1, and the restriction in the vertical direction is not provided for the knitting needle 1 any more. The knitting needle 1 is now constrained by the needle cylinder 8 slot restriction, the vertical restriction being provided by the needle cam 2, i.e. the needle trajectory is controlled by the needle cam 2. After the selector 7 is released, the reset cam 5 pulls the jacquard 6 and the middle needle 3 out of the depth of the groove of the needle cylinder 8 through the reset heel 62 of the jacquard 6, and contacts the knitting needle 1 again to provide vertical constraint for the knitting needle, namely, the knitting needle 1 moves along with the middle needle 3 along the track of the middle needle cam 4 in the vertical direction.
As shown in fig. 1, the needle selector 7 is not in action, the middle butt 32 is matched with the middle needle cam 4, the runway of the middle needle cam 4 determines the motion track of the middle needle 3 in the vertical direction, and the motion track of the knitting needle 1 in the vertical direction is indirectly controlled; as shown in fig. 2, when the needle selector 7 starts to act on the jacquard sheet 6, the jacquard sheet 6 drives the middle needle 3 to move towards the depth of the groove of the needle cylinder 8 under the action of the needle selector 7, and at the moment, the runway of the reset triangle 5 is widened to prevent the interference jacquard sheet 6 from moving towards the depth of the groove of the needle cylinder 8; when the action of the middle needle 3 is finished, the jacquard sheet 6 and the middle needle 3 reach the deep part of the groove of the needle cylinder 8, the middle needle 3 is separated from the knitting needle 1, and the knitting needle 1 is constrained by the knitting needle cam 2 in the vertical direction; when the middle needle 3 needs to be connected with the knitting needle 1 again, the runway of the reset triangle 5 changes, so that the jacquard sheet 6 drives the middle needle 3 to move outwards from the depth of the groove of the needle cylinder 8 until the middle butt 32 and the middle needle triangle 4 are matched again to control the knitting needle 1. Therefore, the knitting needle 1 can move along different tracks in the vertical direction, namely, the state of yarn in the weaving process can be controlled, and the jacquard purpose can be achieved.
The above examples and illustrations are not intended to limit the form or form of the present utility model, and any suitable variations or modifications thereof by those skilled in the art should be regarded as not departing from the scope of the utility model.
