Features and maintenance of single screw plastic granulator
Single screw plastic granulator is mainly used for processing waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer bag, handbag, woven bag, agricultural convenience bag, basin, bucket, beverage bottle, furniture, daily necessities, etc. Suitable for most common waste plastics). Single screw plastic granulator is a widely used and widely used plastic recycling machine in the waste plastic recycling industry.
Features of single screw plastic granulator:
1. All recycled plastics can be produced after being sorted, crushed and cleaned without drying, drying, or drying. Both wet and dry.
2, from raw material crushing, cleaning, feeding to pelletization are all automated.
3. The single-screw plastic granulator makes full use of the high-pressure friction uninterrupted heating system and automatically heats production to avoid continuous heating and save energy and energy.
4. The single screw plastic granulator is mechanically and electrically separated, making operation easier and safer to use.
5. The screw barrels are made of high-strength and high-quality carbon structural steel, which is durable.
6. The appearance of single screw plastic granulator is beautiful. Can be matched with spray paint according to customer requirements.
Maintenance of single screw plastic granulator:
1. Impurities are not allowed in the materials, and hard materials such as metals and sands should be prevented from entering the hopper and barrel.
2. The warm-up time should be sufficient. Generally, the temperature should be kept constant for fifteen minutes after the temperature set by the process is reached. Before driving, the manual turning of the pulley should be brisk.
3. The single screw plastic granulator screw can only be started at low speed, and the idling time can not exceed two minutes. The feeding machine can gradually increase the speed after feeding in hunger mode.
4. The new reducer runs for 500 hours and needs to be replaced with new oil. In the future, the oil quality should be checked regularly. For oil mixed with impurities or aging, it must be replaced at any time. At the same time, the oil level should be checked frequently. It needs to be added in time. From the second time, the reducer is changed for every 3,000 hours of operation.
5. The screw rod of the screw lifting mechanism of the single screw plastic granulator has been filled with low temperature grease before leaving the factory, and then wiped once a week and replenished with grease.
6. When the main motor is a DC motor, check the motor brushes once a month, make a record, and replace the carbon brushes if necessary.
7. The electric control cabinet should be purged once a month.
8. The single screw plastic granulator checks the wear of the screw and barrel every quarter and makes a record.
9. Check the gears, bearings and oil seals of the gearbox once a year.
10.Single-screw plastic granulators should be inspected every day. The contents include the lubrication of each lubricating part, the temperature rise and noise of the bearings at each rotating part, the vibration of the unit, the current and voltage display of the motor and electric heater, and lubrication and cooling. The temperature of the water, the quality of the extruded product, etc.
11. When the machine is stopped for a long time, the machine should be protected against rust and pollution.
