Movable upper pan head mechanism

The utility model relates to a movable upper pan head mechanism. A plurality of sliding devices are arranged on a base; a sliding trolley is fixedly connected to the sliding device; two sides of the sliding trolley are movably connected with supporting rollers; by placing the pan heads on the sliding trolley, longitudinally adjusting the distance between the pan heads through the sliding device and longitudinally sliding the sliding device, the distance between the pan heads can be easily adjusted, and the problems that at present, hundreds of yarns are arranged on one pan head, and the pan heads are arranged on a warp knitting machine one by one, so that the warp knitting efficiency is high are solved. The distance between the pan heads needs to be adjusted on a machine of the warp knitting machine; however, the technical problems that the production efficiency is reduced and the adjustment by personnel is very difficult due to the fact that the adjustment on the warp knitting machine is very difficult are s
