Double-plex extrusion linkage production line with turnover device

Abstract

The invention discloses a double-plex extrusion linkage production line with a turnover device, which has good product quality and high production efficiency. The double-plex extrusion linkage production line comprises a double-plex extruder unit which comprises a first extruder, a second extruder and a complex head, the back side of the complex head is provided with a track which is connected with a receiving roll in a relative rotation way, the tract at the back side of the complex head is sequentially provided with a pre-turnover roll, a turnover roll, a leveling roll and a belt pressing roll in a relative rotation way, the pre-turnover roll, the turnover roll, the leveling roll and the belt pressing roll are all positioned above the receiving roll, the pre-turnover roll is slantly arranged, the turnover roll is vertically arranged, the leveling roll and the belt pressing roll are horizontally arranged, and the horizontal position of the leveling roll is higher than that of the belt pressing roll. The pre-turnover roll is arranged on the tract through a pre-turnover roll connecting seat which is provided with a plurality of pre-turnover roll regulation holes. The turnover roll is arranged on the tract through the turnover roll connecting seat which is provided with a carrier roll in a relative rotation way.

Description

technical field [0001] The invention relates to tire sidewall production equipment, in particular to a double compound extrusion linkage production line with a turning device. Background technique [0002] At present, some of the equipment used to produce tire sidewalls include Φ200 / Φ150 double compound extrusion units, film bonding devices, XJDΦ90×12D extruders, two-roll calenders, cooling spray devices, cutting devices, weighing Devices, double-station coiling devices and other components also include an extrusion linkage line, and the production speed of the extrusion linkage line is 0-30m / min. [0003] The film bonding device can only bond the film above the linkage line. When the sidewall is covered with wear-resistant rubber, the sidewall film should be attached to the side close to the wear-resistant rubber. [0004] When using the existing production equipment to produce the sidewall, in order to ensure that the film is attached to the side of the wear-resistant rub...

AI Technical Summary

Problems solved by technology

[0007] 1. The wear-resistant adhesive has high viscosity, slow heat dissipation, and long extrusion time, resulting in excessive temperature and scorching, so it is necessary to reduce the production line speed (3-4m / min);

[0008] 2. In the Φ150 cold (lower machine) extruder, the sidewall rubber uses a large amount of glue, so the speed is fast and the temperature of the rubber material is high; the residence time in the extruder is short, and the plasticizing effect is poor, which affects product quality;

[0009] 3. The volume ratio of wear-resistant rubber and sidewall rubber in the sidewall is about 1:3, and the corresponding basic capacity ratio of the extruder is about 2:1, resulting in low production efficiency
