Twin Screw Extruder Laying Device
- Jun 01, 2017 -

The auxiliary equipment of the twin-screw extruder mainly includes a feeder device, a straightening device, a preheating device, a cooling device, a traction device, a meter, a spark testing machine and a take-up device. The use of the extrusion unit is different from its optional auxiliary equipment is not the same, as there are cutters, blowers, printing devices.

Structural features

Split-type parallel twin-screw extruder is a significant feature: the barrel can be split at the same time, the screw and barrel liner can be arbitrarily combined.

1, wear situation

Due to the convenience of opening, it is possible to find the degree of wear of the threaded element and the inner sleeve of the barrel at any time, so as to carry out effective maintenance or replacement. And will not be found in the extrusion product problems, resulting in unnecessary waste.

2, reduce production costs

When the masterbatch is made, it is often necessary to change the color. If it is necessary to replace the product, open the open processing area in a few minutes, and the mixing process can also be analyzed by observing the melt profile on the entire screw. At present, ordinary twin-screw extruder in the replacement of color, you need to use a lot of clear machine for cleaning machines, both time-consuming, electricity, and waste of raw materials. The split-type twin-screw extruder can solve this problem, change the color, as long as a few minutes can quickly open the barrel, the manual cleaning, so you can use or less cleaning materials, saving costs.

3, to improve labor efficiency

In the equipment maintenance, the ordinary twin-screw extruder often first to heat, cooling system removed, and then the overall withdrawal of the screw. And split-type twin-screw is not used, as long as the release of a few bolts, turn the worm box handle device lift the upper part of the barrel to open the entire barrel, and then repair. This shortens the maintenance time and reduces the labor intensity.

4, high torque, high speed

At present, the world trend of twin-screw extruder is to high torque, high speed, low energy consumption direction, high speed to bring the effect that is high productivity. Split-type twin-screw extruder that belongs to this category, its speed up to 500 r / min. So in the processing of high viscosity, heat-sensitive materials has a unique advantage.

In the high-speed, high-torque core technology, asymmetric and symmetrical high-torque gearbox is currently only Germany and Japan related manufacturers to master the core technology, the maximum speed can reach 1800 rpm, and the domestic master of this core technology, Only Sichuan in a technology, is currently the domestic high-end materials processing manufacturers one of the main options, are independent national innovation projects

5, a wide range of applications

Wide range of applications, can be applied to a variety of materials processing

6, high yield, high quality

It has the advantages of ordinary twin-screw extruder, which can achieve high yield, high quality and high efficiency.
