PVC steel wire transparent hose forming process

PVC transparent plastic hose, PVC plastic hose, PVC transparent hose with high pressure, tensile, oil, acid and alkali and good transparency and other characteristics, pvc steel wire transparent hose is widely used in automobiles, ships, machinery, Petrochemical industry, such as suction, can transport a variety of liquids, gases.

 

PVC steel wire transparent tube forming principle

 

PVC plastic hose is pvc, glass fiber, metal wire and other recycled fabric as the middle of the hose to play a role in the middle of the hose. The key to its formation is the network of woven around the fabric, according to the way the fabric can be divided into the mold around the mold and the mold around the weaving. At present, most of the foreign countries around the mold weaving method, this method can produce better pvc steel wire transparent hose.

 

PVC steel wire transparent hose process:

 

Ingredients → Mixing granulation → Extrusion extruder I wall tube → cooling → Winding → Extrusion No. Ⅱ extruder outer layer → cooling → traction → light inspection → reeling → packaging → finished product.

 

PVC steel wire transparent tube forming equipment and device design

 

pvc steel wire transparent tube forming equipment, the main extruder, the deputy extruder, the nose, air-cooled devices, weaving mesh devices and traction, light inspection, coiling device.

 

1. Main and secondary extruders

pvc steel wire transparent hose specifications generally Φl2-Φ50mm range, so the choice of Φ45mm, extruder can be squeezed random L / D = 20, divided into four sections of heating, stepless speed regulation, two machine center High are l00mm.

 

2. head (die)

Head design depends on the size of pvc steel wire transparent hose size, its design is reasonable or not affect the quality of the hose forming quality.

 

3. around the device

It is composed of left and right weft shuttle and fixed shaft. According to the level of enhanced index, one or more sets of weaving device can be designed. Each set of weaving device can also design multiple left and right latitude and multi-diameter lines, Both ends are mounted on the left and right shuttle, each shuttle can be equipped with 1 to 5 bobbin winder, when the drive shaft rotates around the shuttle, the bobbin winding on the continuous extrusion pvc wire Transparent hose wall tube, according to the speed of tube extrusion and the density of the required mesh, to determine the shuttle speed and the number of bobbin coil, usually each turn on a l-2 A prism core volume can play a significant enhancement. The warp threads pass through the thread holes in the fixed shaft without rotation.

 

4. cooling air ring

Pvc transparent steel wire hose is often water-cooled stereotypes, but taking into account the tube out from the I number will soon enter the outer coating of No. II die plastic, so I die out of the tube can not Cooling with water, but with the air ring cooling, otherwise, the tube of water bubbles will affect the quality of products, the air ring cooling, the air volume control at Q = 1500m3 / hr or so, the use of the lips wind ring.

 

5. Traction device

Traction device with the same general traction hose, pvc wire mesh in order to ensure the transparency of the regularity of mesh fabric, traction and the machine can also be linked around the weaving device.

 

6. Optical inspection and winding device

Optical pick-up box is used to test pvc steel wire transparent hose wall thickness uniformity and the degree of rules of the network, with a 60-watt fluorescent tube into the box with a glass can, the winding device friction clutch to keep rewinding tension.

 

Through the northern method of production of pvc transparent steel wire hose quality stable and reliable, greatly reduced production costs, the price is only about 1/3 to 1/2 of the rubber tube, and transparent, oil, flame retardant, weight, life expectancy and so on Performance is much better than rubber tube. Therefore, in the actual production of a promotional value.
