PVC steel wire transparent hose molding process.

PVC transparent plastic hose, PVC hose, PVC steel wire hose transparent high pressure resistance, tensile, oil resistant, acid and alkali resistance and transparency, good characteristics of transparent PVC wire hose is widely used in automobiles, ships, machinery, petrochemical and other industrial pump, can transport a variety of liquid and gas.
PVC steel wire transparent tube forming principle.
PVC plastic hose refers to the flexible hose which is used as the middle layer of the hose, which is made of PVC, glass fiber and wire. The key of its forming is the weaving of the mesh, which can be divided into the inner and outer weave of the fabric. At present, most of the foreign countries adopt the outer wrapping method, this method can produce the ideal PVC steel wire transparent hose.
PVC steel wire transparent hose process:
Ingredients – mixed granulation – # I extruder extrusion wall tube billet – cooling – woven around – # Ⅱ extruder extrusion cladding outer – cooling – traction – light inspection to coiling, packaging and finished products.
PVC steel wire transparent hose forming equipment and device design.
PVC steel wire transparent hose molding equipment, which consists of main extruder, auxiliary extruder, machine head, air cooling device, weaving net device and traction, illumination inspection and take-up device.
1. Main and auxiliary extruder.
PVC steel wire of the specifications of the transparent hose is in commonly Φ l2 – Φ 50 mm, so choose Φ 45 mm, extruder, crowded random screw length to diameter ratio L/D = 20, four period of heating, stepless speed regulation, high are l00mm two machine center.
2. Machine head (die head)
The design of the machine head depends on the size of the PVC steel wire transparent hose, and its design is reasonable to affect the molding quality of the pipe.
3. Weaving device
Turn around by the weft knitting spindle and fixed axis, according to enhance the index of the high and low, can design a set or more sets of round knitting device, each group around the knitting devices, and can design more about root parallel and root diameter line, fixed axis about respectively installed on both ends of the spindle, every turn on the spindle can match into 1 ~ 5 bobbin thread volume, turn around when the shaft drive spindle rotates, the bobbin launch was around on the inner wall of the continuous extrusion of PVC steel wire hose transparent tube billet, according to the tube billet extrusion speed and light filling degree of the netting, turn to determine the speed of the spindle and the bobbin thread volume how many, usually each turn crowded with l – 2 core roll edges which can have a significant effect. The warp threads are threaded through the fixed axis and are not rotated.
4. Cooling air ring
PVC steel wire transparent hose is usually adopts water cooling stereotypes, but considering the number from the I die head tube billet is then entered into Ⅱ die head coated outer plastic, so the I number of tube billet extrusion can’t water cooling, and cooling wind ring, for otherwise, water will produce bubbles on the tube billet and affect the quality of the product, the wind ring cooling, the air volume control in Q = 1500 m3 / hr, with lips wind ring.
