Application : The double compound extruding line unit is mainly used for continuous extrusion of semi-steel radial tires, all-steel radial truck tires, bias tires and engineering radial tire treads, sidewalls and apex, etc. Tire tread and other parts of the various parts of the use of different properties, the choice of different formulations of rubber, through two different specifications of the pin-type cold feed extruder in the composite machine head composite of various specifications of radial tire components.
It can be compounded as follows:
(1) composite of crown rubber and shoulder rubber and base rubber;
(2) composite of side rubber and sub-wear wear rubber and rubber;
(3) composite of apex;
(4) Extrusion of shoulder pad rubber.
2. Structural features:
(1) This type of machine adopts advanced pin-type cold feed extruder as the working host; it adopts normal temperature feeding, and the extruded products have good compactness, high output and low energy consumption, and the drive system adopts DC speed regulation. Wide speed range, small size and precise control.
(2) The composite head is driven by full hydraulic pressure; under the hydraulic drive, the operation of opening, closing and locking the machine head is very simple. The flow plate, pre-form and lip plate can be replaced according to product specifications, ensuring stable size.
(3) Temperature control adopts a temperature control system that can automatically adjust the temperature, and automatically adjusts the temperature of the production process within the range set by the process to ensure the extrusion temperature of the product.
