Technical Field

The invention relates to the field of hosiery machines, in particular to a sock moving and grabbing device.

Background

The hosiery machine is modern knitting equipment with high intelligence degree by adopting a mechanical-electrical integration technology, and is widely applied to the knitting industry.

In the process of knitting the sock, the mechanism for knitting the sock body and the mechanism for sewing the sock head are placed at different positions, so that the sock body needs to be transferred to the mechanism for sewing the sock head for sewing after knitting is completed. The sock moving system commonly used at present generally adopts a transfer disc to convey a knitted sock body to the upper part of a sock absorbing long tube, then uses a sock moving plate to hook the sock body and guides the sock body into the sock absorbing long tube, and then the sock body is conveyed to a toe sewing mechanism through the sock absorbing long tube, so that the sock moving work is completed.

However, the existing sock moving system has the following defects:

1. due to the soft texture of the sock, without a definite shape, it is difficult to ensure 100% catching of the sock with the transfer plate and to move each sock accurately into the suction sock cylinder, possibly resulting in some socks getting stuck or the transfer plate being in a position that is difficult to reach.

2. The transfer dish of current hosiery machine is difficult to fix sock body edge completely when fixed sock body, leads to sock body part to drop easily, and the position that sock body was caught by the transfer dish is blocked easily when breaking away from in addition, leads to sock body can't be inhaled and inhales in the socks long section of thick bamboo.

3. The mode that current hosiery machine adopted the transition to coil and moved the cooperation work of socks board, need the transition to coil and move socks board and work in proper order for the production process complicated, increase wrong probability of occurrence, reduction production efficiency.
