TWIN-SCREW SHEET EXTRUDER

STRUCTURE FEATURES:

1. This machine consumes low energy, and it has simple structure, good self-cleaning property, long useful life, high automationdegree, simple operation, low noise, no environmental pollution, small occupied land area, and convenient maintenance, etc.
2. Both screws have single-head, variable-pitch and variable-depth convergent thread structures, and advanced cone shape. These twoscrews rotate oppositely, and engage with each other as a whole. Both of them are installed at an angle and use flat-opening nozzlesso that the rubber materials are extruded more flatly and smoothly and so that the rubber material extruding and transferring capabilitof the screws is enhanced greatly.
3. The machine barrel has a large opening and its bottom has a downhilstructure. The feeding machine barrel wall has a jacket-typewelded structure, and the sheet extruding roller has a hallow structure. The temperature of all of them can be adjusted and controlledby cooling with water or heating with hot oil/ hot water/ steam, to meet the process requirements for different materials
4. The sheet extruding device is installed on the rack and slideway for the feeding device base, and it can be moved horizontallythrough a manual or pneumatic mechanism to realize its separation and reunion, facilitating the cleaning or replacement of feedinghead.
5. Both of the feeding device and sheet extruding device use Ac frequency conversion technology, to adapt to the processrequirements for rubber sheet or resin sheet production lines, realizing step-less speed adjustment;
6.  The working surfaces of various machine parts contacting materials are plated with hard chromium layer, so they are abrasionresistant and corrosion resistant, and have long useful life.8. The electrical control system employees PLC technology, so it can realize both single-machine control and interlock control withsheet production line. oreover, this machine is equipped with a rubber storage control system based on ulrasonic materia  - metei and pressure sensor, which can direcmatching each other.and control the speeds of the screws and roller to achieve
