A speed measuring device for cross-cutting sheet metal

Abstract

This utility model discloses a speed measuring device for cross-cutting sheet metal, including a fixed plate. A vertically arranged cylinder is mounted on the fixed plate, and a support frame is installed at the bottom of the cylinder. A double-eared fixing seat is provided on the upper surface of the support frame corresponding to the cylinder, and the bottom of the cylinder is fixedly connected to the double-eared fixing seat. A rubber roller is rotatably mounted on the support frame, and the fixed shafts at both ends of the rubber roller are installed inside bearing seats on the side of the support frame. An encoder for detecting the rotational speed of the rubber roller is provided on one side of the support frame. This speed measuring device for cross-cutting sheet metal maintains a constant wrap angle between the rubber roller and the sheet metal by driving the cylinder, and utilizes the friction between the rubber roller and the sheet metal to drive its rotation, effectively avoiding slippage, improving measurement accuracy, reducing measurement deviation, and featuring a simple structure and convenient use.
