Pin-type cold-feed rubber extruder are widely used in China's rubber industry. In the production of radial tires, the helical part has annular grooves, which correspond to three stages of tread extrusion, compound tread extrusion, corner rubber, and various rubber compounds. The pins are inserted directly into the annular grooves of these pins, and under the action of these pins, the rubber material performs the lateral movement, flow movement, and secondary rotational movement. Due to the combined action of these three forms of motion, the core formed by the composite during extrusion can be effectively destroyed. Each time the core passes through the pin, the rubber is split and shared by a pair of pins, each time the screw rotates, which strengthens the kneading and accelerates the rubber in the thread groove. Therefore, high-quality mixing, kneading, and plasticizing compounds can be obtained.
Vim yog qhov ntxig ntawm cov pins, lub peev xwm sib tov, knead thiab plasticize yog txhim kho. Nyob rau hauv tib lub extrusion tej yam kev mob, kev ua hauj lwm ntev ntawm cov ntsia hlau yuav luv luv los ntawm ib nrab piv nrog rau cov zoo tib yam txias pub extruder, thiab lub sij hawm siv nyob rau hauv lub chim yog shortened heev. Yuav luag txhua tus extruders uas tsim cov khoom siv roj hmab siv tus pin-hom txias-pub roj hmab extruders. Hauv kev tsim cov log tsheb tsis zoo, kev siv tus pin-hom txias-pub extruder hloov pauv kub-piv extruder tau dhau los ua ib qho kev sib txawv hauv xyoo tas los no thiab tau tsim sai heev, xws li tread rubber extrusion, ntau yam apex, ntau yam nplaum, thiab lwm yam. . Ntau cov chaw tsim khoom siv extrusion tus pin txias pub roj hmab extruders. Hauv kev tsim cov hoses, koob-hom txias pub roj hmab extruder kuj tseem siv rau sab hauv thiab sab nraud roj hmab extrusion.
