PE foam sheet extrusion line |
|
Product Name:
|
PE foam sheet extrusion line |
|
Description:
|
PE Foam Sheet Extrusion Line is mainly used to extrude EPE sheeting producing equipment (expanded PE which be used as soft package to protect the damage of the goods from shock, squeezing, attrition, etc.). The melted LDPE colophony, butane, talcum powder, anti-shrinking and other additives be mixed, then extrude from the machine and foam at the die-lip. Foam sheet cool by the air ring and the molding ring, and extends to pre-set length of expanded PE sheets.
Production capacity of this machine:100--150 kg/h; Product thickness: 0.5-8 mm;width:900-1,300mm
Components of PE Foam Sheeting Extrusion Line
1.Screw: It is made of the top quality 38CrMnALAn azotized steel. Thermal and azotized treatment and special surface plating made the screw with the characteristics of high intensity and long life. The screw diameter is 105mm, 4740mm long (two-sect style), L/D=1:45.This feature improve the plastifying ability and qualities.
2. Cylinder: It is made with top quality 38CrMnALAn azotized steel. Thermal treatment prevents wearing from long time service. Connections between the cylinder, material feeding sect and die-head employed by flanges.
3. Material-Feeding Sector: Two ends are connected to the cylinder and the gear box. The raw material is sent to the extruder via here. 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, model Z4 2000 31, power 55KW.It is cooled by air. Main motor is connected to the screw in the main machine via the gear box.
5. Butane Input and Butane Pump: The butane pump 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 safety.
6. Input of Shrinkage Resistant Agent and Shrinkage Resistant Agent Pump: Shrinkage resistant 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 than the shrinkage resistant agent??s. This is to insure the production safety.
7. Die-Head: 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.
8. Molding Drum: The width of the expanded PE sheet relies on this sector, so the cooling water or the cooling air should all be provided to this sector.
9. Pull Roller: 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 material. The diameter/length of the draught roller is 480/1,550mm. It is also equipped with a speed-changeable motor so as to timing the drawing speed.
10. Swing out Winding Roller: This part is equipped with a meter 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 winding.
