Components of EPE foam sheet transmission production machines:
It is made of the top quality 38CrMoALA azotized steel. Thermal and
azotized treatment and special surface plating made the screw with
the characteristics of high intensity and long life.
It is made with top quality 38CrMoALA azotized steel. Thermal
treatment prevents wearing from long time service.
Two ends are connected to the cylinder and the gear box. The raw
material is sent to the extruder via it. The user should keep some
cooling water in circulation in order to prevent the temperature
arising, which will result in pastiness and agglomeration of the
raw-material, even block the material-feeding hole.
4.Main-Motor of Extruder:
The main motor is an adjustable AC motor, cooled by air. Main motor
is connected to the screw in the main machine via the gear box.
5.Foaming agent (Butane) Pump:
It is a high pressure measuring pump. This pump jets the
deliquesced butane into cylinder by a high-pressure of 10-15Mpa
(100--150Kg/cm).The butane mixes with the melted LDPE in the
entrance of the machine cylinder. A non-return valve is equipped in
the entrance of butane into the cylinder to insure the melted LDPE
will never shoot back in case that the pressure in the cylinder is
higher than the butane pressure. This is also to insure production
6.Anti-Shrinkage (GMS) Agent Pump:
Sends the heated shrink- resistant agent into cylinder with a
pressure of 10-15Mpa (100-150mm/cm).The melted shrinkage resistant
agent is mixed with LDPE in the shrinkage resistant agent's
entering sector. A non-return valve is equipped in the entering
sector to prevent the melted LDPE from shooting back in case that
the pressure in the cylinder is higher tha n the shrinkage
resistant agent's. This is to insure the production safety.
Melted raw material is extruded from this sector. The raw material
started to froth at entering the die-lip. The thickness of the
expanded PE sheet depends on the die lip and drawing speed.
The width of the expanded PE sheet relies on this sector
The sheets extended by the molding drum should be draught after
entering this sector. At this time the drawing speed should keep
balanced in order to insure the quality of the sheet material.
equipped with a speed-changeable motor so as to timing the drawing
This part is equipped with length counter to set the sheet's
length. It rotates 180 degrees when the winding length of the first
roller reaches the set requirements. Then the second roller starts
