Background

With the progress of technology, air jet looms are widely used due to their high productivity. The air jet loom is characterized in that a heald frame drives warp yarns to move up and down to form a shed, meanwhile, a weft insertion mechanism sprays weft yarns into the shed through airflow, a beating-up mechanism drives a reed to beat the weft yarns entering the shed into a cloth fell, then the heald frame drives the warp yarns of the upper layer and the lower layer to exchange positions to form the next shed, and the warp yarns and the weft yarns are interwoven to form a fabric. In the actual production process, the fabric woven by the air jet loom is wound on a winding drum (which is sleeved on the cloth roller and rotates along with the cloth roller) of an external winding device matched with the air jet loom. When the diameter of the roll reaches a certain requirement, the roll needs to be replaced, and the roll on the cloth roller needs to be removed, and the process is called doffing.

However, the existing winding drum mostly adopts in-situ doffing, so that the operation space of the subsequent process is limited, and the flexibility is poor.

The driving motor 71 is started, the driving motor 71 works to drive the driving screw 72 to rotate clockwise or anticlockwise (when the cloth is doffed and the replacement roller is reeled again, the driving screw 72 rotates along different directions), so as to drive the driving screw 73 to move along the direction perpendicular to the cloth outlet direction of the air jet loom 2 to be away from the upright post 3 (namely to the direction of the driving motor 71), and further drive the sliding rod 62 and the pulley 63 to move in the guide chute 51 and the sliding rail 52 respectively, so that the winding roller 41 can move stably, is away from the air jet loom 2 and the upright post 3, and avoids the upright post 3, and the cloth-doffing operation is performed. Meanwhile, a new winding drum is sleeved on the winding roller 41, the rotating direction of the driving motor 71 is changed, the sliding rod 62 and the pulley 63 move in the guide chute 51 and the sliding rail 52 respectively, and the winding roller 41 moves to a position corresponding to the cloth outlet of the air jet loom 2 smoothly to perform the winding operation again. In addition, the drive motor 71 can be periodically inspected through the access door 8.
