Solution to the blockage of the discharge port of the kneading machine in structural adhesive equipment

The blockage of the kneading machine outlet of the structural adhesive equipment is caused by the long-term accumulation of materials. Before blocking, the device will have current fluctuations and other conditions. Compared to solving common faults, the more critical task is to resolve minor discharge outlets and blockages before they are completed. When the current fluctuation of the kneading machine of the structural adhesive equipment indicates that the material opening will be blocked, the feeding should be stopped and the equipment will be idle for 1-2 hours. Observe whether the current is repaired under full load current. The internal materials are discharged cleanly and neatly. At this point, you can slow down the speed of the device. It can terminate the operation of the equipment, remove the cutting port, and perform manual maintenance to clear and calibrate, and then resume production. On the other hand, once the equipment is depleted again, it can enter the outlet for cleaning and discharging polyformaldehyde liquid. After cleaning, open the inspection hole to check if it is clean and tidy. After sorting, production can be resumed. The material attached to the discharge outlet is hard and cleaning cannot completely solve the problem. It is usually recommended to use a manual shutdown method to remove it.

After the feeding was terminated, the device has been running for some time. The current remains at a high value and cannot be reduced to full load current, indicating that the discharge port has been completely blocked. There is a risk involved in resolving complete blockages during device operation. Firstly, terminate the intermediate and downstream equipment, and then remove the reduction pipe directly below the discharge outlet. During the operation, the material at the discharge outlet of the equipment will spray out anytime and anywhere, so the staff should try to avoid using the equipment as much as possible and use specialized tools such as ropes. Remove the reducer and close the lower pipe hole to prevent material from falling into the damaged middle and lower parts.

After removing the reduction tube from the equipment, the staff should wear protective equipment and use specialized tools to clean the discharge outlet over a long distance. As the blocking material decreases, the nozzle will suddenly spray and discharge all the material in the machine. When the current drops instantly to full load current, the equipment can be terminated, and after maintenance, everything can be produced normally.

The device is completely blocked. The safe solution is to terminate the operation of the equipment, open the top cover of the equipment, remove the material inside the kneading machine barrel of the structural adhesive equipment and the material at the discharge outlet, and then resume production. However, this solution requires a significant amount of labor, typically taking 18 hours to become 4 to 5 times more efficient than other solutions, which seriously damages production time. Therefore, the discharge outlet of the kneading machine of the weather resistant adhesive equipment is blocked. It is important to handle it appropriately in the early stages to prevent complete blockage. Once a complete blockage occurs, a safe solution will be chosen to prevent safety production accidents.
