PVC Corrugated Roof Tile Sheet Extrusion Line
PVC Corrugated Roof Tile Sheet Extrusion LineDescription:
Corrugated roofing sheet production machine is in combination of conical twin screw and single screw extruder. The special designed screw and downstream line make the extrusion more stable and the plasticizing performance better. The auxiliary machine line includes molding machine, automatic fixed-scale cutting machine, rack, haul off, etc. The products are widely applied to the building construction on the decorative requirements and the gallery in the public places. They have the characteristics of excellent corrosion resistance, tough texture, high strength, fine thermal insulation, environmental protection, etc.

Main Points of Installation
1. Choosing square tube (60mm*40mm*3mm) or C shape steel (100mm*50mm*20mm*3mm) or rot proof wood (60mm*40mm) to be purline.
2. Arraying the purlines upwards with the gap of 660mm.
3. Installing the main ridge tile backwards to the wind direction. Connecting up the roof tile wave from both sides at the same time.
4. Cut off part of the first ridge tile before instaling the main ridge tile.
5. Sawing the connection area of the main ridge tile and oblique ridge ile neatly. Installing the main ridge tile and oblique ridge tile before installing the three-way ridge tile.
6. Fastener is special accessory. Drilling a hole whose diameter is 2mm lager than the screw pole by electric drill before installing. Self-tapping screws with 6mm diameter is recommended.
Equipment shutdown notice:
1.1 Before the shutdown, the residual material in the extruder barrel screw should be extruded, and then the stop material should be added to ensure that the residual materials in the screw, die and other parts are excluded as much as possible.
Note: After cleaning the screw and barrel, remove the extrusion die, restart the main machine, add the stop material (or crushed material), clean the screw and barrel, and the screw speed is reduced to low speed to reduce wear. After the material to be stopped is crushed into powder and completely extruded, the residual pellets and powder can be repeatedly blown out from the feeding port and the exhaust port by compressed air, until the barrel does not have residual material, the screw speed is reduced to zero, and the extrusion is stopped. Exit the machine, exit the screw, and check the wear of the barrel and the screw. For light scratches or rough surfaces, grind with oil stone or fine sanding cloth to make it smooth and smooth. Then, vacuum, molding, cutting and other auxiliary machines are sequentially turned off.
1.3 Check the wear of the transmission gear and the rolling bearing, and propose the gear spare parts manufacturing or purchase plan as needed, and prepare for the next maintenance.
1.4 Check the heating temperature of the calibration barrel and the forming mold (measured with a mercury thermometer) and the temperature difference between the meter on the control box to ensure the correct operation of the process temperature during production.
1.5 Test, check whether the water, gas and oil pipelines are unobstructed and leak. The blockage is cleaned and repaired. Check and adjust the electric heating device of each part, the working position of the cooling fan and the safety cover to ensure that they can work normally and effectively.
1.6 The oil in the equipment gearbox and the water in the auxiliary equipment that needs to pass the water, such as the thermostat, vacuum pump, etc., should be completely cleaned. Especially for the northern region, if it is not cleaned and frozen, the pipeline will malfunction and the pipeline will be faulty. Rust and other issues. This item must pay special attention to the fact that in the past years, most customers will have normal problems due to the corresponding failures during the next year.
1.7 The switches in the electrical cabinet need to be completely closed. The motor, fan and the internal low-voltage meter of the auxiliary equipment are used to blow the cleaned dust with the air pipe to prevent the short circuit of the electrical appliance caused by too much dust in the next year, and the service life is reduced. Then lock the seal to avoid being mishandled during the holiday, causing problems in the next year.
