⑴ First of all, adjust the roll distance of the mill to keep the balance of the roll distance. If the size of the roller distance adjustment at both ends is different, the rollers will be eccentrically loaded and the equipment will be easily damaged, which is strictly prohibited.
(2) The feeding is customarily added from the power input end, which is actually unreasonable. From the bending moment diagram and torque diagram, the feed should be at the gear end of the ratio. Since the combined bending moment and torque of the transmission end are larger than those of the speed ratio gear end, adding a large piece of hard rubber at the transmission end is of course more likely to damage the equipment.
(3) Of course, don't add a large piece of hard rubber to the middle section of the roller first, where the synthetic bending moment is larger, reaching 2820 tons/cm.
⑷ The amount of feeding should be gradually increased, the weight of the feeding block should not exceed the stipulation in the equipment instruction manual, and the feeding sequence should be added gradually from small to large. As shown in the figure, a large piece of rubber material is suddenly added into the roller gap, which will cause overload and rush out, which will not only easily damage the safety gasket, but also endanger the roller once the safety gasket fails.
⑸ When operating, the knife should be scratched (cut) first, and then the glue should be held in your hands. The film is not scratched (cut), and it is not allowed to pull hard. It is strictly forbidden to feed the material on the roller with one hand, and pick up the material under the roller with the other hand. When pushing the material, you must make a fist and not exceed the horizontal line at 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 cutter must be placed in a safe place (to prevent the cutter ring from entering the rubber material and bringing it into the roller), the cutter must be fed in the lower half of the roller when tapping, and the cutter must not face the direction of 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 is suddenly cooled, that is, when the temperature of the roller is found to be too high, the cooling water is suddenly introduced, and the roller will be damaged under the combined action of the transverse pressure and the temperature difference stress. Therefore, cooling should be carried out gradually, preferably with empty vehicles.
⑻ When the roller is running and it is found that there are sundries in the rubber material or the roller, or there is accumulated glue at the baffle rubber and the bearing bush, it must be stopped. If the conveyor belt accumulates glue or fails, it must also be stopped. In case of sudden stop, the power supply should be cut off in sequence, and the water and steam valves should be closed. Driving with load is strictly prohibited.
⑼ It is forbidden to rely on or stand on the rotating parts of the equipment and the material tray; it is not allowed to convey objects above the running rollers;
When pulling and pushing the vehicle, pay attention to the surrounding conditions to prevent collision and collision with people.
