After the installation of the opener is completed, it needs to be tested before it can be officially put into use. There are also certain test requirements during the test. The opener manufacturer recommends choosing an area of more than 8 square meters for installation. A rubber sheet should be attached to the bottom of the opener to ensure the flatness of the equipment and reduce vibration. What operations are the openers mainly affected by? Before using the opener, check whether all rotating parts and bolts are tightened, loose or falling off. Also add an appropriate amount of lubricating oil to the transmission parts such as sprockets and gears. After determining the direction, start the engine. Determine the direction of rotation of the opener, and then feed evenly. All raw materials in the machine need to be processed before powering off, and then the power is cut off. The speed of the opener beater will affect its strength in hitting the cotton layer. During the operation of the opener, if the beater rotates at a high speed, it has a better effect of opening and removing impurities from the cotton. If the speed is too high, impurities are easily broken, thereby reducing the impurities that fall off the cotton. The opener manufacturer tells you that when processing raw bridges with long fibers, few impurities or low maturity, a lower batter grade is generally used.
