Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

As shown in fig. 1-3, the utility model provides a general FCT structural design, it mainly comprises upper and lower two parts, and the first half is mainly for going up the needle bed drive arrangement, and the latter half is mainly for the pneumatic quick change device 5 of needle bed.

The driving device mainly comprises: the motor 2, the screw rod 7 and the guide rail 11;

the needle bed quick-change device mainly comprises: locking bar 9, needle bed 5, needle bed slot, industrial connector 13, guide groove 12 and other parts.

With reference to fig. 1, the upper needle bed driving device has an X-shaped suspension 3, and the left and right lift arms have the same structure and include upper arms 31 and lower arms 32, the upper ends of the upper arms are hinged to the top of the fixed frame 1, the lower ends of the upper arms are hinged to a connecting block, the connecting block is hinged to the upper ends of the lower arms, and the lower ends of the lower arms are hinged to the lift platform.
