Rubber filtering and vulcanizing treatment process for automobile tire tube manufacturing rubber material

Abstract

The invention relates to the field of tire manufacturing, in particular to a rubber filtering and vulcanizing treatment process for automobile tire tube manufacturing rubber material. A rubber filtering and vulcanizing treatment device for automobile tire tube manufacturing rubber material is used and comprises a main body, a rotating table and a collecting pipe, and the main body is of a cylindrical structure; a rotating groove is formed in the top of the main body, the rotating table is rotationally connected into the rotating groove, the rotating table is of a cylindrical structure, a plurality of inserting grooves penetrating through the rotating table are formed in the rotating table in the circumferential direction of the rotating table in an annular distribution mode, connecting grooves are symmetrically formed in the inner walls of the inserting grooves, spring rods are arranged in the connecting grooves, and supporting plates are fixedly installed at the tops of the spring rods; and collecting pipes are inserted into the inserting grooves and each of the collecting pipes is a circular-pipe-shaped structure. The rubber filtering and vulcanizing treatment device is used for extracting molten regenerated rubber in a reciprocating circulation manner, the filter screen can be cleaned independently after extraction, and the rubber filtering and vulcanizing treatment device is suitable for popularization.

Description

Technical field [0001] The present invention relates to the field of tire manufacturing, and more particularly to an automotive tire inner tape treatment process. Background technique [0002] The car tire is known as the tire, refers to a circular elastic tube for keeping the internal pressure of the tire and a tire gas door mouth. The valve nozzle is used to inflate and maintain the air in the inner tube. The inner tube should have good airtight, heat resistance, elastic, aging, and smaller permanent deformation. It is generally made of butyl rubber. [0003] At present, in order to reduce manufacturing costs, recovering regenerated rubber often uses recycled regeneration in the manufacture of car tires, and a large amount of sand or metal foreign matter will remain in the regenerated rubber, which cannot be used directly. Therefore, before using regenerative rubber, it needs to be regenerated. Rubber is filtered, remove impurities in the rubber, and in order to increase the fl...

Problems solved by technology

[0003] At present, in order to reduce manufacturing costs, recycled recycled rubber is often used in the manufacture of automobile tire inner tubes, and a large amount of sand or metal foreign matter often remains in the recycled rubber, which cannot be used directly. Therefore, before using recycled rubber, it is necessary to clean the recycled rubber The rubber is filtered to remove the remaining impurities in the rubber. At the same time, in order to improve the flexibility of the regenerated rubber, it is usually necessary to add vulcanization after filtration to vulcanize the rubber. However, most of the current rubber filtering devices have single functions and are usually passed The extrusion device drives the molten regenerated rubber forward, passes through the filter screen, and filters out the impurities in the regenerated rubber, but the filtering effect of this filtering method is not good. After a long time of filtering, a large amount of impurities will stick to the filter. It causes blockage, which affects the filtration efficiency of regenerated rubber. At the same time, when the regenerated rubber in the existing rubber filtering device is discharged, most of them are in the form of several thin strips and are directly exposed to the air, which is not conducive to collection. Usually, it needs to be recycled after collection. It is easy to make the dust in the air contaminate the regenerated rubber during the cooling and solidification process, which will affect the quality of the regenerated rubber.
