Blocky rubber continuous mixing method and device

Abstract

The invention discloses a blocky rubber continuous mixing method and device. A crude rubber conveying device is used for feeding a blocky rubber raw material into a rubber continuous plastifying device and conveying a solid compounding agent and an extruded plastifying rubber sheet into the rubber continuous mixing device; a rubber feeding controlling device and a compounding agent feeding controlling device are connected with an equipment control system; and the blocky rubber raw material is directly put into the blocky rubber continuous plastifying device to be continuously plastified without prophase treatment, plastified rubber is mixed through the rubber continuous mixing device, and continuous production of continuous feeding, discharging, continuous plastifying and continuous mixing is realized. The blocky rubber continuous mixing device has the advantages of less quantity of auxiliary devices, little investment of production devices, low energy consumption, high efficiency, and high mixing quality because stable device parameters and process conditions can be realized due to strong controllability.

Description

technical field [0001] The invention belongs to a processing method and equipment of rubber processing and molding equipment, in particular to a method and equipment suitable for continuous mixing of block rubber. Background technique [0002] my country is a big country in rubber production and consumption. Achieving high efficiency, low energy consumption, and large-scale production of high-quality rubber products is an important problem to be solved urgently at this stage in our country. At present, the commonly used mixing equipment in our country is the internal mixer and the open mixer. Since they are all intermittently operated, there are the following defects: (1) The strong shearing action of the rotor is converted into heat energy of the rubber material, which requires a complex cooling system. (2), intermittent production requires constant parking, unloading, and loading, and the production efficiency is low. In order to make up for this defect, the volume and ex...

Problems solved by technology

[0004] The present invention solves the technical problems of existing continuous mixing and extruding equipment, such as many pre-mixing procedures for blocky rubber raw materials, complicated auxiliary equipment, large investment in production equipment, and high energy consumption, and provides a kind of rubber that does not need to be processed in block shape. The raw materials are pre-treated, directly put into the plastic mixer for continuous plastication, and the block rubber continuous mixing method and the equipment used are continuously, efficiently and high-quality mixed by the mixer
