Abstract

The utility model discloses a kind of extrusion equipment of preparation bonded ferrite material, the extrusion equipment of preparation bonded ferrite material includes organic platform, high mixing device, extrusion device, cooling device and cutting device. By being provided with temperature detection module between the input end of cutting device and the output end of cooling device, the temperature detection module is connected with control box, again cooperate temperature detector and be located extrusion strip directly above and be set on crossbeam part, after extrusion device extrusion forming has extrusion strip, extrusion strip is drawn under the traction of traction roller, pass through temperature detection module after cooling device, temperature detector detects extrusion strip surface temperature, if temperature exceeds 50 ℃, temperature detection module sends corresponding signal to control box 1, so that its extrusion speed of extrusion device and the speed of traction roller are adjusted, to extend the stay time of extrusion strip in sink, and then make its temperature can be smoothly cooled to below 50 ℃, avoid staff scald.
