Device for automatic separation and resetting of needle rods of double-needle machine

The invention provides a device for automatic separation and resetting of needle rods of a double-needle machine. The device comprises a sliding shaft, one end of the sliding shaft is connected with a separating assembly, the other end of the sliding shaft is connected with a resetting assembly, the separating assembly comprises a swing rod and a driving rod which can conduct straight reciprocating motion, one end of the swing rod is connected with the sliding shaft, the other end of the swing rod is connected with the driving rod, the middle portion of the swing rod can be rotatably connected with an installation frame, the driving rod is connected with a driving mechanism, and the driving mechanism is connected with an automatic control system. According to the device for automatic separation and resetting of the needle rods of the double-needle machine, the driving mechanism is controlled by the automatic control system to act, so that the sliding shaft is driven to act, and the needle rods are separated; stitch numbers of single needle rod walking are controlled by the automatic control system, so that the stitch numbers of single needle rod walking before and after rotation of a sewing material during corner sewing are consistent, and the sewing precision and the sewing stability are improved; and the operation of the corner sewing is simplified, so that the speed of the corner sewing is accelerated, and the production efficiency is effectively improved.
