Twin-Screw Sheet Extruder for Rubber Processing Xjy-Sz 250

Product Description

Deyu twin-screw rubber sheet extruder
This machine is lower supporting equipment for rubber internal mixer, is high-efficiency and ideal novel thick-sheet extruding equipment
special for internal mixer or dispersion mixer. It is used for forced extrusion of melting body and continious production of thick sheets
after rubber, plastic, synthetic resin and nonmetal material etc.
Structure features:
1) this machine consums low energy and it has simpe structure, good self-cleaning property, long useful life, high automation degree,
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 two screws rotate oppositely, and engage with each other as a whole, both of them are installed at an angle and use flat-opening
nozzles so that the rubber materials are extruded more flatly and smoothly so that the rubber material extruding and transfering capability
of the screws is enhanced greatly.
3) the machine barrel has a large opening and its bottom has a downhill structure, the feeding machine barrel wall has a jacket-type
welded structure, and the sheet extruding roller has a hallow structure. the temperature of all of them can be adjusted and controlled
by 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 horizontally
through a manual or pneumatic mechanism to realize its separation and reunion, facilitating the cleaning or replacement of feeding head.
5) both of the feeding device and sheet extruding device use AC frequency conversion technology, to adapt to the process requirements
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 abrasion resistant
and corrosion resistant, and have long useful life.
7) the electrical control system employees PLC technology, so it can realize both single-machine control and interlock control with
sheet production line, moreover, this machine is equipped with a rubber storage control system based on ultrasonic material 1 - meter
and pressure sensor, which can directly detect and control the speeds of the screws and roller to achieve matching each other.
