⑴First of all, adjust the roll pitch of the mill to maintain the balance of the roll pitch. If the two ends of the roll distance adjustment are not the same, it will cause the rollers to be unbalanced and easily damage the equipment. This is strictly forbidden.

⑵It is customary to add materials from the input end of the power source. In fact, this is unreasonable. From the perspective of the bending moment diagram and the torque diagram, the feed should be at the end of the gear ratio. Since the combined bending moment and torque of the transmission end are greater than that of the gear end, it is easier to damage the equipment by adding a hard large piece of rubber to the transmission end first.

⑶Of course, don't add a large piece of hard rubber to the middle section of the roller first, where the combined bending moment is larger, reaching 2820 tons/cm.

⑷The feeding amount should be gradually increased, the weight of the feeding block should not exceed the regulations in the equipment manual, and the feeding order should be continued from small to mainland. As shown to save trouble, a large piece of rubber is suddenly added to the roller pitch, which will cause overload and rush out, which will not only damage the safety gasket, but also, once the safety gasket fails, it will endanger the roller.

⑸ When operating, you must first draw (cut) the knife, and then take the glue with your hands. The film is not drawn (cut), and it is not allowed to pull hard. It is strictly forbidden to feed the material on the roller with one hand, and to receive the material under the roller with the other hand. When pushing the material, you must make a half fist, and do not exceed the horizontal line of the top of the roller. When measuring the temperature of the roller, the back of the hand must be opposite to the direction of rotation of the roller.

⑹The cutting knife must be placed in a safe place (to prevent the cutting knife ring from entering the rubber material into the roller). When tapping the rubber, the knife must be fed in the lower half of the roller. The cutting knife is not allowed to face your body. When making a triangle bag, it is forbidden to operate with a knife. When making a roll, the weight of the film must not exceed the rated weight of the model.

⑺ During the operation of the roller, the hot roller suddenly cools down, that is, when the temperature of the roller is found to be too high, the cooling water is suddenly introduced, and the combined action of the transverse pressure and the temperature difference stress will cause the roller to be damaged. Therefore, cooling should be carried out gradually, preferably with an empty vehicle.

⑻When the roller is running, if there is debris in the rubber or in the roller, or there is glue accumulation at the baffle rubber, bearing bush, etc., it must be stopped for treatment. If there is glue accumulation on the conveyor belt or malfunction, it must be stopped for handling. If you encounter a sudden stop, you should cut off the power in order and close the water and steam valves. It is strictly forbidden to drive with load.

⑼It is forbidden to lean on or stand on the rotating part of the equipment and the material tray; it is not allowed to transfer objects above the running roller;

Pay attention to the surrounding conditions when pulling and pushing the vehicle to prevent collisions and people, and prevent heavy overturning and injury when loading materials.
