Applications of Pin-Type Cold-Feed Rubber Extruders
Time：
2017-07-22
Pin‑type cold‑feed extruders are constructed by mounting multiple rows of pins at specific locations along the screw barrel or the extruder cylinder. These extruders come in various configurations, including pin‑barrel screw extruders, pin‑cylinder extruders, pin‑main‑and‑auxiliary‑threaded‑screw extruders, and pin‑transfer extruders. Pin‑type cold‑feed extruders are primarily used for shaping and extruding tread compounds and other components in tire manufacturing; for producing shaped profiles such as rubber hoses, rubber sheets, rubber plates, conveyor‑belt carcass adhesives, and cover rubbers; for continuous coating of wires, cables, and rubber hoses; and they can replace open‑mill operations, supplying adhesive to wire (fiber)‑reinforced calendering machines and radial‑tire inner‑liner calendering machines.

Pin‑type cold‑feed extruders are primarily used for the profiled extrusion of various tire components, such as tread; for the profiled extrusion of products with diverse cross‑sections, including rubber hoses, rubber sheets, rubber plates, and cover compounds for conveyor belts; for the continuous coating of wires, cables, rubber hoses, and other articles; and to replace open‑mill systems by supplying rubber to wire (fiber)‑reinforced fabric calenders and radial‑tire inner‑liner calenders.
I. Feeding Device
1. Structure: The feeding unit comprises a feed-section screw, a barrel, and a feed roller, which together enhance the material‑feeding performance and incorporate three‑sided sealing to eliminate glue leakage. The feed roller rotates in the opposite direction to the screw, enabling forced feeding.
2. Temperature Control: Temperature control plays a decisive role in ensuring the extrusion process operates normally. Multi-point temperature regulation is implemented, with temperature control applied to both the feed rollers and each section of the barrel.
3. Transmission System: The transmission system is driven by a DC motor to accommodate variable-speed operation and speed regulation.
