A kind of rapid prototyping equipment for the production of plastic masterbatch with high stability

Abstract

The invention discloses high-stability rapid forming equipment for plastic master batch production. A mounting frame is fixedly connected to the top end of a supporting table, a supporting plate is fixedly connected to the top end of the mounting frame, an extruder is fixedly connected to the top end of the supporting plate, and a forming mechanism is fixedly connected to an output port of the extruder; and the forming mechanism comprises a conveying pipe, a pressurizing pipe, a connecting frame, a fixed spring sleeve, a pressurizing spring, a sliding spring sleeve, a conical plug, a buffer cavity, an extrusion hole, a cooling tower, a baffle, a dividing plate, a distributing plate, a supporting base, a sliding groove, a buffer spring, a sliding block, a driven shaping roller and a drivingshaping roller. According to the high-stability rapid forming equipment, through cooperation of all components of the forming mechanism, the diameter of extruded plastic strips is kept consistent, sothat the internal structures of the plastic strips re more compact, the polymer properties of an assistant and filler in the plastic master batch are more stable, and assistant and filler falling caused by an unstable skin structure of plastic master batches is prevented.

Description

technical field [0001] The invention relates to the technical field of plastic masterbatch production equipment, in particular to a highly stable rapid prototyping equipment for plastic masterbatch production. Background technique [0002] Plastic masterbatch means that in the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and then measured, mixed, melted and processed by extruders and other equipment. Granules produced by extrusion, pelletizing and other processing processes. The masterbatch is composed of carrier resin, various fillers and various additives. The limit of additives in the masterbatch or the content of fillers is higher than the actual plastic product. It is several times to more than ten times higher. During the processing and molding of masterbatches, special equipment needs to be used to shape plastic masterbatches; [00...

AI Technical Summary

Problems solved by technology

[0003] However, in the plastic masterbatch production equipment currently on the market, during the production process, the molten plastic discharged from the extruder is directly pelletized after being cooled by the water tank, resulting in unstable structures of various additives and fillers on the surface of the plastic masterbatch. It is easy to fall off from the surface of the plastic masterbatch during the process, which reduces the product quality of the plastic masterbatch
