Problems solved by technology

In the existing production process, whether primary extrusion or secondary extrusion refining is used, the materials are extruded by the roller of the refiner at the same speed, and the reclaimed rubber produced often does not meet the performance of high-quality rubber. Utilization of reclaimed rubber is limited

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0013] Such as figure 1 As shown, the reclaimed rubber refining unit consists of four refining machines. The following takes a refining machine as an example to describe in detail, see figure 2 , 3 , the refiner frame 3 is set on one side of the base 8, a pair of extruding rollers 1 are arranged on the frame, and rubber stoppers 6 are arranged at the middle of both ends of the pair of rollers, and the rubber stoppers are used to prevent leakage of raw materials . The lower end of the roller is provided with a rubber disc 5 . A rubber scraper 7 is installed on the rubber outlet side of the refiner to scrape off the excess part of the produced reclaimed rubber, so that the regenerated rubber can enter the next refiner in a regular shape. The outside of the rubber scraper is provided with a support roller 2 for sending the reclaimed rubber to the next refiner. The...

Abstract

The invention relates to a regenerated rubber refining unit. The refining unit comprises refining mills, and is characterized by comprising four refining mills with different rotational speeds. The refining unit has the characteristics of four times of extrusion refining of regenerated rubber, realization of increase in strength and stretch rate and other performance of regenerated rubber by controlling the rotational speeds of the refining mills and production of regenerated rubber which has a strength up to between 17 and 70MPa and meets industrial requirements on strength of the regenerated rubber.

Description

technical field [0001] The invention relates to a device for producing reclaimed rubber, in particular to a refining unit for producing regenerated rubber. Background technique [0002] The refining process of reclaimed rubber is realized by extruding the material through the roller of the refiner. The refining process is used to improve the technical indicators such as strength and elongation of the reclaimed rubber to make it meet the use requirements. In the existing production process, whether primary extrusion or secondary extrusion refining is used, the materials are extruded by the roller of the refiner at the same speed, and the reclaimed rubber produced often does not meet the performance of high-quality rubber. The utilization of reclaimed rubber is limited. Contents of the invention [0003] The object of the present invention is to provide a refining unit for producing reclaimed rubber, through which the refining unit refines the reclaimed rubber multiple time...
