Description
Technical Field
The utility model relates to a tire apparatus for producing field says in detail that a four compound tire side wall that is suitable for embedded white side wall of production extrudes mouth of a mouthful type in advance.
Background
As is well known, with the development of the tire industry, the demands of people on tire products are more and more diversified and personalized. Therefore, in order to meet individual requirements of people, tires with white, red, blue and other colored sidewalls are produced. Among various colored tires, white sidewall tires are currently the most widespread and most commercially available. The white sidewall tire is generally formed by extruding black sidewall rubber, white sidewall rubber and bead filler rubber in a compounding manner when a sidewall part is extruded. The white tyre side parts produced by the three-composite extrusion have white glue exposed outside. In order to prevent the white glue from being polluted by molding or vulcanization and influence the attractiveness of the white glue, two methods are generally adopted in the industry for treatment. The first mode is as follows: the method comprises the following steps of (1) modifying equipment on an extrusion line before a tire side component enters a cooling water tank, covering a layer of black rubber sheet on white rubber, carrying out the same forming and vulcanizing procedures as the production process of a common black tire side tire, and finally polishing off black rubber coating on white rubber of a vulcanized finished tire to expose the white rubber to finish the manufacture of the white tire side tire; the second mode is as follows: and (3) normally coiling the extruded white tire side as the black tire side, manually attaching a layer of black rubber sheet on the white rubber in the forming stage to ensure that the white tire side rubber is completely covered, and after vulcanization, polishing off the black rubber on the white rubber of the finished tire to expose the white rubber, thereby finishing the manufacture of the white tire side.
It is known that the production of white sidewall tires at home and abroad basically adopts the mode of hot film pasting during extrusion or manual film pasting during molding. The two modes have different defects, the first mode needs to improve equipment in an extrusion process, a small extruder, a small open mill and a paster device are usually added, a black rubber sheet with proper width and thickness and calendering is compounded with white rubber before the tire side enters a cooling water tank in an extrusion production line, and black rubber coating on the white rubber is ground after vulcanization. This increases the cost of equipment modification and also increases the operational difficulty for workers. The second method is to add a step in the molding process, i.e. manually attach a layer of black rubber sheet on the white side rubber, and polish off the black rubber coating on the white rubber after vulcanization. The mode can lead in impurities to pollute the white glue due to the fact that the white glue is exposed outside in the cooling and reeling process and the cooling auxiliary line, the cooling water and the cloth liner are in direct contact with the white glue, and therefore the attractiveness of the polished white glue is affected.
Tire enterprise generally can not additionally purchase white child side extrusion lines when producing white side wall tire, can use original black ordinary side wall production line usually, and present domestic tire side wall extrusion lines is mostly two compound or three compound, use original mouth of a mouth type device on current side wall extrusion lines, if do not reform transform equipment or increase the step, then can't realize extruding two side walls simultaneously, and one of them is ordinary side wall, another is embedded white side wall, this development of white and other colored side wall products that has restricted the tire enterprise.
