The opener can adjust the width of the cotton yarn, and the drum roller is a special cotton yarn processing machine that integrates cotton yarn pressing and kneading with fan dust removal. The opener is suitable for removing cotton lint, old cotton tires, short chemical fibers and other items. The opener loosens the compressed and entangled fiber materials and removes impurities. It can loosen a variety of textile materials, such as cloth scraps, carpet materials, car interiors, non-woven fabrics, waste cotton yarn, roving ends, waste clothes, etc. What is the working principle of the opener? What should be paid attention to? The working principle of the opener is: the cotton to be processed is fed into the cotton curtain, roller, paper feed roller and continuous feeding evenly due to the rotation of the drum, under the strong control of the cotton layer. When the cotton and friction of the sawtooth hook are greater than it, the combed cotton fiber with the controlling force is pierced off bit by bit. The cotton wool is separated into a single fiber state. Under the action of the high-speed operation of the drum, a large centrifugal inertia force is generated, and impurities are continuously thrown out along the tangent direction of the outer circle of the drum. Due to the small specific gravity of cotton fiber, under the action of airflow, the opener sends it to the surface of the dust cage through the cotton delivery channel to form a layer of cotton. Then send it to the next two feed discs. The formed cotton layer is fed into the cotton roller and wrapped around the surface of the wooden roller by itself. In daily use, we often encounter abnormal working of the opener. The reasons for these failures are very simple, and most of them are caused by improper operation. More often, it is due to our negligence in maintaining the machine, and long-term operation causes various failures of the machine. Matters needing attention In daily use, care should be taken to avoid damage to the opener due to improper operation. Correct operation is very effective for the maintenance of the machine. In daily use, special attention should be paid to the operation of the opener, and the various parts of the machine should be maintained to extend the service life of these parts. In the process of daily use, as long as attention is paid to correct operation, mechanical failures can be effectively avoided, thereby effectively ensuring the service life of the machine. This is an introduction to the working principle and precautions of the opener. When using the opener in daily life, everyone should operate it according to the correct method of use to ensure its service life.
