4. Safety Operation Details
, Preparation Work Before Operation Inch Open Mixer|Taiwan Precision Open Mixer
⑴ Must check before opening the open mixer Are the circuits (current and voltage, etc.), oil circuits (lubrication of reducers, bearings, etc.), water circuits, etc. normal? Then wear leather wrist guards (it is strictly prohibited to wear gloves), wear a mask during mixing operations, and absolutely avoid waist ties, belts, rubber, etc., and it is strictly prohibited to operate with clothes on. Check carefully whether there is any debris between the large and small gears and rollers. When driving for the first time in each shift, the emergency braking device must be tested to check whether the braking is sensitive and reliable (if it is a knee-impact device, you must be used to touching your knees to the braking device). It is strictly forbidden to use the emergency braking device to shut down the vehicle during normal operation. If two or more people are operating together, they must respond to each other and confirm that there is no danger before driving. Inch open mill | Taiwan precision open mill
⑵ The temperature rise rate must be controlled when preheating the roller. 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 outside may be above ℃, and the stress on the roller caused by the temperature difference can reach 3.~~., which exceeds that of cast iron. If rubber is added too early, the roller will be easily damaged under the superposition of lateral pressure. For safety reasons, the truck should be preheated when empty and refueled and lubricated when empty. Material should be added when the temperature reaches or is close to the set temperature value. This needs to be emphasized to the operator.
⑶ The rubber material should also be checked before feeding. If there is hard metal debris mixed with it, it will be thrown into the rubber mixing machine with the rubber, resulting in a sudden increase in lateral pressure and damage to the equipment. Inch Open Mixer | Taiwan Precision Open Mixer
, Key precautions for feeding and rubber mixing operations Inch Open Mixer | Taiwan Precision Open Mixer
⑴ First, adjust the roller distance of the open mill to maintain Roller distance balance. If the roller distance adjustment at both ends is different, it will cause the roller to be unbalanced and easily damage the equipment. This is strictly prohibited. Inch open mill | Taiwan precision open mill
⑵ It is customary to add materials from the power input end. In fact, this is unreasonable. Looking at the bending moment diagram and torque diagram, the feed should be at the speed ratio gear end. Since the resultant bending moment and torque at the transmission end are greater than those at the speed ratio gear end, adding a large piece of hard rubber to the transmission end will of course make it easier to damage the equipment.
⑶ Of course, do not first add large pieces of hard rubber to the middle section of the roller, where the resulting bending moment is larger, up to tons/cm. Inch open mill | Taiwan precision open mill
⑷ The amount of feeding should be gradually increased, the weight of the feeding block should not exceed the regulations in the equipment instruction manual, and the feeding sequence should be added from small to large. As shown in the figure, if a large piece of rubber material is suddenly added to the roller gap, it will cause overload and rush out, which will not only damage the safety gasket, but also endanger the roller once the safety gasket fails.
⑸ When operating, you must first score (cut) the knife, and then take the glue with your hands. Do not pull or pull the film before it is cut (cut). It is strictly prohibited to feed material on the roller with one hand and receive material under the roller with one hand. If the rubber material jumps and is difficult to roll, do not press the rubber material with your hands. When pushing material, you must make a half-clenched fist and do 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 in the opposite direction to the rotation of the roller. Inch Open Mixer | Taiwan Precision Open Mixer
⑹ The cutting knife must be placed in a safe place (to prevent the cutter knife from encircling the rubber material and bringing it into the roller). When tapping the rubber, the knife must be inserted into the lower half of the roller, and the cutting knife must be placed in a safe place. Do not point towards your own body. When punching triangular bags, it is prohibited to operate with a knife. When punching rolls, 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 roller temperature is found to be too high, cooling water is suddenly introduced. Under the influence of transverse pressure and temperature difference stress, Under the combined effect, it will cause damage to the roller. Therefore, cooling should be carried out gradually, and it is best to cool down with an empty vehicle.
⑻ During the operation of the roller, if it is found that there are debris in the rubber material or the roller, or there is glue accumulation in the baffle rubber, bearing bush, etc., it must be stopped for processing. If there is glue accumulation or failure on the conveyor belt, it must be stopped and dealt with. If there is a sudden stop, the power supply should be cut off in sequence and the water and steam valves should be closed. It is strictly prohibited to drive with a load.
