[0002] Computer flat knitting machine is a very commonly used processing equipment for processing some knitted products such as wool sweaters and cashmere sweaters. The knitting needles and stitches are installed on the needle plate. After searching, the Chinese patent authorization number CN203373517U discloses a computer knitting flat knitting machine needle plate. The needle plate isolates the knitting needles and sinkers to avoid direct contact and friction between the knitting needles and the sinkers, thereby improving the service life of the knitting needles and sinkers. However, the existing computer flat knitting machine needle plate structure consists of two needle plates, and a knitting needle is placed in a needle groove on each needle plate. The needle length formed by one needle groove and one knitting needle cannot be suitable for full-formed knitting, and spacer knitting must be used. However, the problem of large needle length caused by spacer knitting also leads to the problem that the density of the knitted fabric cannot be made tight, and the density of the knitted fabric with normal needle length cannot be achieved. For this reason, this scheme provides a two-needle plate structure for full-formed knitting of normal density, two knitting needles are arranged in one needle groove, and can be switched by a switching mechanism to output any needle in one needle groove. The structure is simple and the cost is low. Utility Model Content

The shaft 8 passes through all the needle grooves, and the cross-sections of both ends of the switching shaft 8 are semicircular structures. A groove is provided at one end of the knitting needle 3, and the shape of the groove at one end of the knitting needle 3 is consistent with the shape of one end of the left switching needle 41 and the right switching needle 42, and one end of the left switching needle 41 and the right switching needle 42 are respectively engaged with the grooves at one end of the two knitting needles 3, and the left switching needle 41 and the right switching needle 42 are placed in the same needle groove, and the left switching needle 41 and the right switching needle 42 correspond to two knitting needles 3 respectively. Long needles 5 are provided above the tails of the left switching needle 41 and the right switching needle 42, and when the long needle 5 is in the reset state, the head 51 can be engaged with the switching needle 3. The right tail groove 423 and the left tail groove 413 of the needle changer are engaged and disengaged. A downwardly protruding head 51 is provided at the bottom of one end of the long needle 5. The shape of the head 51 matches the left tail groove 413 and the right tail groove 423. The left tail groove 413 and the right tail groove 423 are respectively opened at the ends of the left switching needle 41 and the right switching needle 42. When the switching shaft 8 is not actuated, the top plane of the switching shaft 8 is parallel to the needle plate 1, and the left switching needle 41 and the right switching needle 42 are both in a sinking state. The head 51 of the long needle 5 is disengaged from the grooves of the left switching needle 41 and the right switching needle 42. The left bottom groove 414 and the right bottom groove 424 of the left switching needle 41 and the right switching needle 42 are engaged with the steel wire 9 on the needle plate 1, and the engagement of the left tail groove 414 and the right tail groove 424 with the steel wire 9 is a limit to prevent inaccurate resetting caused by external uncertain factors and affect the next needle lifting and engagement action. By rotating the switching shaft 8 clockwise to a certain angle, the switching needle is lifted up to the tail groove to engage with the head 51 of the long needle 5, and the long needle 5 is actuated by the external triangle, thereby driving the switching needle to move, and finally driving the knitting needle 3 in the needle groove that cooperates with the switching needle to perform various weaving actions.

[0027] Embodiment 2:

[0028] The switching shaft 8 is rotated clockwise, and the first vertex 81 of the switching shaft 8 fits against the right bottom surface 422 of the right switching needle 42, and the right switching needle 42 is lifted to the right tail groove 423 and fits with the head 51 of the long needle 5. The long needle 5 is actuated by the external triangle, thereby driving the right switching needle 42 to actuate, and finally driving the knitting needle 3 in the needle groove that cooperates with the right switching needle 42 to perform various knitting actions. The switching shaft 8 cooperates by counterclockwise rotation, and the second vertex 82 of the switching shaft 8 fits tightly with the left bottom surface 412 of the left switching needle 41. The left switching needle 41 is lifted up to the tail groove and fits with the head 51 of the long needle 5.
