Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 3, the cam plate of the computerized flat knitting machine of the embodiment includes a motor 1, a first cam 2, a second cam 3, a middle cam guide block 4, a needle-turning guide block 5, a seesaw 6, a spring 7, a support frame 8, a motor support 9, and the like.
Wherein, the motor 1 is installed on the motor bracket 9, and the direction indicated by the arrow A in fig. 1 is taken as the front, the output shaft 11 of the motor 1 extends forwards out of the motor bracket 9. The support frame 8 is arranged at the front side of the motor support frame 9, the front side and the rear side of the bottom of the support frame 8 are respectively provided with a first through hole 81 for the head of the Zhongshan guide block 4 and the needle turning guide block 5 to pass through, and the Zhongshan guide block 4 is positioned at the rear side of the needle turning guide block 5.
