Abstract: A rubber V-belt yarn blank coating and cutting device is described herein. The rubber V-belt yarn blank coating and cutting device is numerically controlled and includes a frame and a base compound rubber leading-out device, a base compound rubber conveying device, and a base compound rubber coating and cutting mechanism sequentially disposed on the frame. The base compound rubber coating and cutting mechanism includes a driving roller and a driven tensioning roller disposed on the frame and further includes grouped round cutting knives and a squeezing roller. The squeezing roller is positioned between the driving roller and the driven tensioning roller, and the grouped round cutting knives with a sliding mechanism are disposed above the squeezing roller. The coating and cutting device in the present invention is simple in structure, high in cutting precision, labor efficiency and operational safety, and convenient to mount.

Abstract: An automatic canvas wrapping machine including a canvas conveying device, a yarn core mounting device, a canvas wrapping device, and a cutting device is described herein. The canvas conveying device conveys a rubberized canvas for wrapping a yarn core. The yarn core mounting device is disposed in a conveying direction of the canvas conveying device, and the yarn core is mounted in the yarn core mounting device and attached to the rubberized canvas conveyed by the canvas conveying device. The canvas wrapping device is disposed on one side of the yarn core mounting device and presses the rubberized canvas reciprocatingly along a direction vertical to the conveying direction, so as to tightly attach the rubberized canvas to the yarn core. The cutting device is disposed at an upper part of the canvas conveying device and cuts the rubberized canvas after the canvas wrapping device completes canvas wrapping.
