| PP woven bag production line : PP/PE flat yarn extruding ,stretching machine -plastic woven bag making machine Having passed ISO 9001 quality anthentication, our machinery are manufactured by adopting micro-computer control, frequency conversion adjustment, and automatic change filter, they are: A) The mainframe adopted new-type high-effective extruder B) The mantle bolt adopt 38CrMoA1A treated by nitriding the surface of the material with higher corrosion resistance and wearing strength C) All the driving motors are adopted electromagnetic governor motors, flexible and convenient in adjustment and can perform the infinitive stage transmission by controller D) The oven can be provided two types according to the requirements of the client: 1) Traditional curved oven, it is cheaper. 2) Pulling & extending oven with up & down circulating warm wind close to the international technical level in 1990s - this unit has the merit of high output, low energy consumption, compact structure, good quality, steady running, easy operation, good-looking outline, safe and reliable, etc. Plastic pp woven sack making machinery: High Speed PE/ PP Flat Tape yarn Extruder Line for the cement, fertilizer bags The flat yarn making machine is adopted micro-processor control, frequency conversion governor and setting and displaying technical data may be fully digitized on the basis of absorbing international advanced techniques. The main parts use quality products. The line enlarges L/D ratio and adopts new type of separating screw and widens mixing smelt zone on the extruder screw pot which is specially processed using quality steel, fine plasticized effect, low energy consumption in relation to output. For the change filter system of the flat film stretching line, we apply advanced automatic belt change filter. The bake-board is changed into advanced hot drawing oven and principal technical index of the line reaches international advancing level. The winding machine is of friction-free drive and constant tape tension wind, good formation quality of the fiber drum. The line has the performance of high speed, top yield, low energy consumption, good forming quality of the fiber drum. The structure of the line is compact with a pleasing appearance, smooth running, flexible and reliable control, sophisticated manufacture engineering, convenient operation and reliable production, it can be used in producing flat fiber form thermoplastic, such as polypropylene (PP) and high-density polyethylene (HDPE) etc |
