1. Application:

the pin barrel rubber extruder is mainly used for the shaping extrusions of rubber compounds at room temperature. when fitted with different extruder heads, it can achieve many rubber products in rubber industry, for example, exruding of inner tubes and tire treads, coating of rubber tube and conveyor belt, shaping extrusion of profiles of rubber sheet and plate. in addtion, it also incorporates into a multiple extrusion unit together with other (hot or cold feed) rubber extruders.

pin barrel extruder has good plastifying and mixing properties which can result in uniformity goods, low extrusion temperature , high extrusion capacity , low powe consumation, wide processing adaptability.

 

2 Structures features:

the pin barrel extruder consists of motor , reduction gear box, feed device, screw, barrel, extrusion head, temperature control unit, electric control device and frame , and so on.

main motor is a DC motor with DC speed adjuster, gear reducer is multi-step tooth surface hardened type, and immersion lubrication/oil pump are adopted. feed device is double-walled design for water cooling, and feed roll is designed for water cooling with a rotary joint and adjustable scraper knife for continuous cleaning and is driven by splined coupling ring. screw is made of nitrided steel 38CrMoAIA, surface hardened by nitriding, nitriding depth 0.5~0.7mm, and surface hardness 900HV, extrusion barrel is drilled for water cooling and heating with 7~12 pin rows, each have 6~12pins and is made of nitrided steel 38CrMoAIA in bore surface hardened by nitriding, nitriding depth 0.5~0.7mm, and surface hardness approx.950HV. temperature control unit(TCU) for the cooling of screw, pin barrel, feed barrel, feed roll, and extrusion head. frame is welded by steel profiles.
