Winding drum structure capable of positioning printing materials

Abstract

The winding drum structure capable of positioning the printing material comprises a support, a supporting plate is fixedly installed on the left side face of the support, a hydraulic rod is fixedly installed on the upper surface of the supporting plate, a control block is fixedly installed at the telescopic end of the hydraulic rod, and a sliding groove is formed in the left side face of the support; a sliding block is slidably connected to the inner wall of the sliding groove, the left side face of the sliding block and the right side face of a control block are fixedly installed, and a toothed plate is fixedly installed on the right side face of the sliding block. According to the device, by arranging a motor, a positive and negative threaded rod, a threaded hole and a clamping plate with a hole, a material arranged outside a winding drum in a sleeving mode can be clamped, the clamping plate can position the material, the device can be suitable for materials of different lengths and sizes, and a toothed plate can move up and down through cooperation of a hydraulic rod, a control block, a sliding groove and a sliding block; and the toothed plate can be matched with the gear to position the rotating shaft, so that rotation during stopping is prevented, and the stability of equipment is ensured.
