Information
The open mill focuses on use and maintenance. Good operating habits and process protection can greatly increase the life of the machine and reduce the safety factor of the operator when using it. Protecting the safety and health of workers in production is an important policy of our country. Protecting national property and promoting production development are important duties of enterprise management.
1. You must wear leather wrist guards before mixing. Wear a mask during mixing operation. Absolutely avoid waist ties, belts, rubber, etc., and dressing operations are strictly prohibited. Check carefully whether there is any debris between the large and small gears and rollers.
2. Every time you drive, you must pull the emergency brake device to check whether the brake is sensitive and reliable (the pull rod emergency stop and emergency reverse emergency stop device, the reverse device can be set for 0-5 seconds, generally set to 1-2 seconds, ( There is a time delay switch in the machine to adjust) This is to avoid the loss of the machine that cannot be repaired in the process of the operation experiment, and serious personal injury. This operation is suitable for the emergency action of foreign objects falling into the roller) , It is strictly forbidden to shut down the car with an emergency brake device during normal operation. If two or more people are working together, they must respond to each other. After the mill is confirmed that there is no danger, adjust the roller pitch and maintain the balance of the roller pitch. If the adjustment of the roller pitch at both ends is different, it will cause the rollers to be unbalanced and easily damage the equipment. This is strictly prohibited.
3. Master the heating rate, especially in the cold winter in the north, the outside of the roller is consistent with the room temperature, and high-temperature steam is suddenly introduced into the roller. The temperature difference between the inside and the outside may be above 120℃, and the temperature difference can cause the roller stress to reach 130.0~~I50. 0MPa, which has exceeded U.1=140.OMPa for cast iron. If the rubber material is added too early, the roller can be easily damaged under the superimposed action of the transverse pressure. For the sake of safety, the empty car should be preheated, and the requirement that the heating rate is directly controlled at 1~2℃/min is very difficult to implement, and it needs to be emphasized to the operator.
  4. The rubber material should also be checked before feeding. If there are hard metal impurities, put it into the rubber mixing machine with the rubber, causing the horizontal pressure to suddenly increase and directly causing equipment damage. Or the operator’s cutting knife fell into the roller during the test. There is a special protective device here. The operator presses the control door with his knees (there is a sticker on the machine table). I have already said it before, and I have repeatedly emphasized it. this point. Note for open mill: When feeding the material, it should be added little by little. If the sample is very hard, it may cause the machine to burn out.

The rules before turning on the mill must be followed one by one!
The correct operation of the mill must first adjust the roll pitch and maintain the balance of the roll pitch. If the adjustment of the roller pitch at both ends is different, it will cause the rollers to be unbalanced and easily damage the equipment. This is strictly prohibited. After the work is finished, cut off the power supply and close the water and steam valves.
