Overview

The industrial two-stage water ring hot cutting machine currently mainly produces complete sets of equipment such as parallel twin-screw extrusion units, single screw recycling granulation units, two-stage mixing units, and plastic sheet extrusion units, which are widely used in the fields of ordinary plastics, engineering plastics, thermosensitive polymers, plastic polymerization reactions, etc.

　　Industrial double stage water ring hot cutting machineMalfunctions and their handling methods

1. The screw is running normally without discharging

Reason: Discontinuous feeding of the hopper; Foreign objects blocking or creating "bridging" at the feed inlet; A hard metal object falls into the screw groove and blocks it, preventing normal feeding

Solution: Increase the feeding amount to ensure continuous and stable screw feeding; Stop the machine to remove foreign objects from the material outlet and eliminate the "bridging" phenomenon; If it is confirmed that a metal foreign object has fallen into the screw groove, the machine should be stopped immediately to disassemble the screw and eliminate the metal foreign object.

2. Exhaust hole emitting material

Reason: The raw materials are not clean enough and contain impurities; The feeding speed is too fast, which makes the screw extrusion unstable; Insufficient plasticizing temperature causes problems with screw extrusion.

Solution: Clean the raw materials before feeding or replace the filter screen; Reduce the feeding amount to ensure smooth extrusion of the plasticizing stabilizing screw; Raise the plasticizing temperature.

3. The host does not rotate or stops instantly

Reason: The power supply of the main motor is not connected; Insufficient heating time or one of the heaters not working, resulting in excessive torque and motor overload.

Solution: Check if the host circuit is connected and turn on the power supply; Check the temperature display of each section, confirm the preheating and heating time, check whether each heater is damaged or has poor contact, and eliminate it.

　　Industrial double stage water ring hot cutting machineMaintenance Method

1. Firstly, the air-cooled hot cutting granulator should be placed in a ventilated position to ensure the heat dissipation of the motor during operation and extend its lifespan. Lubricating oil should be regularly added to the bearings to ensure lubrication between them;

2. Regularly check the screws of the cutting tools. After using the brand new air-cooled hot cutting granulator for 1 hour, use tools to tighten the screws of the moving and fixed knives, and strengthen the fixation between the blade and the knife holder;

3. To ensure the sharpness of the cutting edge of the tool, it is necessary to regularly inspect the tool to ensure its sharpness and reduce unnecessary damage to other components caused by blunt or missing blade edges;

4. When replacing the cutting tool, the gap between the moving tool and the fixed tool should be 20HP or above. The thinner the recycled material, the larger the gap can be adjusted appropriately; Before the second start-up, the remaining debris in the machine room should be cleared to reduce start-up resistance;

5. The inertia cover and pulley cover should be opened regularly to remove the ash outlet under the flange, as the powder discharged from the air-cooled hot cutting granulator chamber enters the shaft bearing;

6. The air-cooled hot cutting granulator should be well grounded.
