Abstract

The invention relates to a novel application of a refining device on a device for automatically controlling an extruder to discharge material uniformly, wherein the device for automatically controlling an extruder to discharge material uniformly comprises a controller, a raw material hopper, a rack, a feed hopper and a weighing device, wherein the raw material hopper and the feed hopper are respectively arranged on the upper end and the lower end of the rack, and a lower outlet of the feed hopper is connected with a feed port of the extruder; a lower outlet of the raw material hopper is provided with an automatically controlled raw material gate; an input end of the controller is connected with the weighing device, an output end of the controller is connected with a motor of an extruding screw of the extruder or a driving motor of a traction roll, and an upper surface of the feed port of the extruder is connected with a material blending device. 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] In production practice, it is often necessary to mix several raw materials with different particle sizes and materials (such as adding color masterbatch and other additives). Small, but the specific gravity is large), resulting in unevenness of various materials in the process of mixing raw materials from the raw material hopper to the extruder, resulting in unevenness of the extruded product (uniformity in the length direction, uniformity in thickness and poor color uniformity). In addition, the structure of the weighing device is complicated, and the use and maintenance are troublesome. Contents of the invention [0003] Th...
