We are equipped according to different forms of the different rubber screw and barrel (forced feeding system), to feed fast, out of material balance, high quality products.

Pin cold feeding extruder feeding device the second sealing system, including feeding a and feeding a docking with the feeding door, feeding holder and feeding door with right between the bearing, right near the bearing connection pressure roller, feeding door and feeding a combined with the combination of the sealing face slot, seal grooves in the near side pressure roller bending inwards extensions and connected to right outside the bearing surface, the seal groove with rubber sealing strip, rubber seal at the end of the article and right outside the bearing surface connectivity, right on the appearance and bearing with rubber seal at the end of the article mutual staggered type O the rubber sealing ring, O type rubber sealing ring and right outside the bearing surface to form a seal, rubber seal at the end of the article and right outside the bearing surface connected to the second sealing.

Due to the secondary seal can ensure that work in a state of the infiltration reduce oil pressure roller, ensure that extruder feeding device sealing effect, avoid lubricants by infiltration pressure roller into rubber, can effectively improve the quality of the products.
