Route detection device of waste material extruding cylinder

Abstract

The invention relates to a route detection device of a waste material extruding cylinder. The route detection device comprises an extruding cylinder shearing blade. The route detection device is characterized by being further provided with a positioning guide groove, a slide rod, a metal rod, electromagnetic sensors and a bracket, wherein the slide rod is fixedly connected with the edge of the extruding cylinder shearing blade; the positioning guide groove is fixedly arranged on the bracket; the axis of the positioning guide groove is parallel to the axis of the extruding cylinder shearing blade; the slide rod is located in the positioning guide groove and is in sliding fit with the positioning guide groove; the metal rod is vertically fixedly arranged on the slide rod; the bracket is fixedly arranged on the foundation; three to six electromagnetic sensors are distributed on the bracket; the distance between each electromagnetic sensor and the metal rod is adjustable; the metal rod is matched with every electromagnetic sensor in sequence. According to the route detection device of the waste material extruding cylinder, the detection device outside the extruding cylinder is used for replacing an encoder in the extruding cylinder so that the defects that sensing devices are easy to damage and detection signals are fluctuated are overcome; the working rate of a set is improved and the utilization period of the extruding cylinder is prolonged; the maintenance working amount and the maintenance cost are reduced. The route detection device of the waste material extruding cylinder is simple in structure, low in cost and stable to operate.

Description

technical field [0001] The invention relates to a detection device, in particular to a stroke detection device of a waste extruding cylinder. Background technique [0002] Household appliance panels and automobile panels are mainly produced on the high-speed continuous annealing line. The waste extruder is one of the key equipment of the line. The process requires the waste extruder to run continuously without interruption. Very important. Existing extrusion cylinder stroke detection encoders are usually installed in the extrusion cylinder. Because the cylinder body is too long and the pressure in the cylinder is high, the detection signal fluctuates or the encoder is damaged. Repairing is a heavy workload, time-consuming and labor-intensive, which seriously affects normal production. Therefore, it is very necessary to design a scrap extrusion cylinder stroke detection device with simple structure, low cost, stable operation and the ability to greatly prolong the service l...
