Analysis of operating procedures of hot air stenter setting machine

1.After driving, check whether the mechanical, electrical, instrumentation and safety protection devices are in good condition.Set the temperature according to the process requirements, then turn on the circulation fan. During the heating stage, the main machine speed is 15m/min. When the set temperature is reached, the cloth can be put on.After meeting the cloth loading requirements, open the active brush wheel, press the cloth on the needle plate, and make both sides as aligned as possible. In addition, put down the passive brush wheel and tighten the fabric.When starting the main machine, the bell should be rung to notify the operator at the rear of the vehicle. When the cloth reaches the rear of the vehicle, the cloth should be put on as quickly as possible and the fabric should be tightened. The operators at the rear of the vehicle should cooperate with each other to call forward and respond.

2.The safety protective cover at the entrance and exit of the machine should be intact to prevent the clothing clips from catching on the sleeves. In addition, it can also prevent the chain from breaking and flying out and injuring people.

3.The emergency stop switch pulled by the rolling rope and the cloth feeding safety lever are reliable and effective. You must stop the machine during cloth threading operation and unscrew and lift the upper roller. Do not be careless.

4.The gray fabric must be seamed and no knots are allowed to prevent damage to the rubber roller and cause accidents.

5.After shutdown, the temperature drop should be reported to the heat transfer oil furnace room.Then stop the circulation fan, open the door to cool down, and run the main machine and the top exhaust fan in a single operation. Stop the machine when the temperature drops to 80°C, which can avoid uneven heating of the chain card clothing clips.

6．Regularly check the thermal oil pipes in the oven. If there is oil leakage, it should be dealt with in time. The flying dust in the machine should be cleaned after the first shift, and the flying dust and oil stains in the exhaust duct should be removed regularly to eliminate fire hazards.

7.Add a steam pipe above the exhaust duct at the bottom of the oven to use steam to cool down and extinguish fires. When the temperature inside the machine reaches 165°C, the steam valve is in a normally open state; a wire mesh guard is installed on the heat sink to prevent flying flowers or Fabric dropped on the radiator causing burning.

8.The car must be turned off when doing cleaning work or refueling. It is strictly prohibited to wipe the chain, brush the needle plate, or wipe the rollers (especially the upper and lower rollers) while driving to prevent finger injuries.. When cleaning on or inside the aircraft or repairing the vehicle, a stop sign must be hung on the operating console to prevent accidents caused by other people driving.
