For extruding a hose-like or tubular preform extrusion head, with the extruder plasticized plastic is extruded monolayer or multilayer preform wall of the tubular extrusion head (10) pressing the small peanuts oil machine parts, extrusion head is squeezed by the so-called system works. Wherein a plurality of the same or the same type of head (11,12,13) ??each having an annular shape around the discharge passage and / or the flow passage (24,68,79,102,110), and optionally manner in series. Each head has at least one helical flow divider (40,52,60, or 97), the apparatus by means of a ring slit (47,94) introduced into the discharge passage and / or the flow channel. Press pressing screw shaft is already pressing screw shaft down on the basis of the temperature of the device, set the QS-G type bi-tube fixed rotary joint and supporting the joints and metal hose, upon request, steaming or cooling water, pressing screw shaft to achieve the purpose of heating or cooling press fitting gear, "a type of dual-use" Zhengzhou How can press fitting, easy operation and press parts, reduce labor intensity and improve work efficiency, there is no media leaks. Press juice bar accessories, Aikawa press accessories, Henan light wreath can be reached by Henan Machinery Manufacturing Co., Ltd. can be reached. Henan can Machinery Manufacturing Co. (www.zhayoujia.com) strong, credible, in Zhengzhou, Henan Province edible oil processing machinery industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve the innovation capacity of Henan ideas will lead into the brilliant and you work for a better future!
