Cleaning Hot Air Stenter properly help to extend service life of machines. I would like to introduce some cleaning information for you below.

All the printing and dyeing company wants to make full use of stenters and maintain high evaporation efficiency. Once the equipment is put into use, it's the manufacturer's own business.

One of the defects of common stenters is the decrease of efficiency caused by the clogging of the cotton dust filter. During each operation, the cotton dust and other impurities filtered out from the circulating air system of drys gradually accumulate, generate resistance, reduce the pressure of the air vent, and thus decrease the evaporation efficiency.

At present, many dryers and heat treatment equipment are still using a plug-in filter. If they do not open the door of the drying room, the machines cannot be cleaned. Because the cleaning of the filter and the re-heating of the drying room will waste time, it will have a bad impact on the production efficiency of the equipment.

The double-filter system introduced in the data about 6 years ago is a big step forward. This device is installed outside of the machine and can be taken out without opening the drying room door. It can be cleaned without stopping the machine. When the filter is pulled out, the other filter automatically replenishes the position. The pressure still decreases due to the accumulation of cotton flock, which means the efficiency will also be reduced.

Printing manufacturers understand that although cotton flock is removed and a basic cleaning is carried out on each shift, the filter screen will gradually become clogged and therefore require frequent thorough cleaning. Above all, the filter screen must be removed and cleaned with detergent by a high-pressure cleaning device.

Several Tips We Need to Know about Hot Air Stenter.

1. Check the mechanical, electrical, instrumentation and safety protection devices before turning on the machine. According to the process requirements, set the temperature, and then turn on the circulating fan. During the heating stage, the host speed is 15m/min, and the cloth cannot be put until the set temperature is reached. After meeting the requirements, open the active brush wheel, press the cloth on the needle plate, try to make both sides flush, and at the same time put down the passive brush wheel and tighten the fabric. When starting the host, you should first ring the bell to inform the tail operator. When you put it to the rear of the car, you should put on the cloth at the fastest speed and tighten the fabric. The rear personnel should cooperate with each other.

2. The safety cover of the machine should be in good condition to prevent the needle cloth from hanging around the sleeves, and avoid fly out and hurt people on account of the chain break.

3. The emergency stop switch pulled by the rolling rope and the safety loss of the feeding cloth are reliable and useful. The machine needs to be stopped when the cloth is operated.

4. The grey cloth must be seamed and not allowed to be knotted to avoid damage to the rubber roller.

5. Before turning off the Flat Screen Printing Machine , the cooling should be reported to the hot-loaded heat transfer furnace room. Then stop the circulating fan operation, open the door to cool down, and run the main engine and the top exhaust fan separately. When the temperature drops to 80℃, the machine can avoid uneven heating of the chain clothing.

6. It’s of great importance to regularly check the heat transfer oil pipeline in the oven. If oil leakage appears, it should be dealt with in time. After the shift, the fly flower should be cleaned. The fly and oil in the exhaust pipe should be cleaned regularly to eliminate the fire hazard.
