Equipment features of PVC pipe one out four production line

A four-pipe extrusion production line is to produce four pipes in one mold. Under the premise of ensuring product quality, the equipment greatly reduces equipment input cost, plant input cost and production input cost, greatly improves output and reduces production time.

The diameter range of production pipe is 16mm-40mm

2. Total installed power: about 75KW

3. Production capacity: compared with the one-out two-tube extrusion line, the output increased by 70%.

16-32 allocation list of one-out-four extrusion equipment production line:

1. 65/132 twin screw extruder:

2. One out of four molds and one set of fixed sets:

3. Stainless steel vacuum sizing cooler:

4. Ink printer:

5. One out and four tractor:

6. One-out four-cutting machine:

7, a four-turn rack

PVC extruding equipment with one out and four casing

1) because of the characteristics of the conical screw, the feeding section has a large diameter, which is conducive to the plasticization of the material due to the large heat transfer area and shear velocity of the material, and the small diameter of the measuring section screw reduces the heat transfer area and the shear velocity of the melt, so that the melt can be extruded at a lower temperature.

(2) a quantitative feeding device is installed to match the amount of extrusion with the amount of feeding and ensure the stable extrusion of products.

(3) in the quantitative feeding device, the user should add magnetic body to prevent the fall of iron sundry matter and protect the screw.

(iv) because the screw is in the shape of a cone, the small end is the measurement section, with a small cross-sectional area and a small axial force; on the contrary, the large end has a large space and can be installed to bear a larger axial load force.

(5) a distribution gear box is set and the driving torque is evenly distributed to each screw through the distribution gear box.

(6) cast aluminum electric heater is used to heat the drum, with long service life and convenient assembly and disassembly.

(7) strong air cooling is adopted for cylinder cooling, with small temperature fluctuation.

(8) adopt ac frequency conversion speed regulation device to make the main motor stepless speed regulation, stable speed and convenient speed regulation.

(9) the frequency converter has a variety of protective measures to prevent the damage of the parts.
