The invention relates to a device for automatically controlling an extruder to discharge material uniformly, which comprises a controller and a weighing device, wherein the weighing device comprises a raw material hopper, a rack, a weighing hopper and a feed hopper, the raw material hopper and the feed hopper are respectively arranged on an upper end and a lower end of the rack, and a lower outlet of the raw material hopper is provided with a gate; the weighing hopper is arranged between the raw material hopper and the feed hopper, one side of the weighing hopper is connected with one end of a lever, the other end of the lever penetrates out of the rack and is provided with a counter weight, and a fulcrum of the lever is hinged on the rack; a material supplement sensor is arranged aside the lever; and a lower outlet of the weighing hopper is provided with a material discharge sensor. A feed port of the extruder is provided with a material blending device, and a lower end of the feed hopper is communicated with a lower end of a shell of the material blending device through an inclined tube. The invention has the advantages that a structure is simplified, the manufacturing cost is reduced, a control principle is simple, the operation is easy, the precision can meet production needs, the maintenance and the debugging are easy; and the uniformity of length, color and thickness of products is greatly improved.
Description
technical field [0001] The invention relates to a device for automatically controlling the uniform discharge of an extruder, which is used to control the uniformity of the length, thickness and color of the discharge on film blowing machines, extruding machines, plastic winding machines and spinning (rod) machines . Background technique [0002] The prior art adopts an electronic scale to measure the feed rate, and then controls the extrusion screw or the traction roll speed of the extruder according to the feed rate, so that the feed rate is inversely proportional to the speed of the extrusion screw, or is inversely proportional to the traction roll speed. The rotation speed is proportional to keep the film thickness uniform. Its disadvantages are complex structure, high cost, and difficult maintenance and debugging; and the use of solid flow sensors to measure the flow of granular raw materials is only suitable for specific raw materials. Once the raw materials are replac...
