In production, when the brocade composition changes greatly or there are different requirements for the quality of the yarn, the licker-in noil must be adjusted in time; if there is a big difference in the mechanical state of each machine, it is also necessary to make necessary adjustments to the licker-in noil. Adjustments in order to achieve stable production, quality assurance and cotton savings. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The factors that affect the noil of the licker-in roller of the carding machine are also quite complex. In summary, there are several different situations as follows: The dust removal knife of the carding machine not only plays the role of shooting down debris, but also distributes the length of the first and second foreign matter areas. Fiber has a certain role of straightening and holding, and also has the function of crushing impurities and changing the trajectory of impurities. The location of the dust collector includes height and height, installation angle and distance from the drum.
Dust removal knives are based on low vehicle surfaces, generally in±Adjust within the range of 6nun. Above the surface of the car, flush with the surface of the car and lower than the surface of the car, they are called high knife, flat knife, and low knife technology. The high and low position of the dust removal knife is mainly determined by the impurities in the cotton layer.
The installation angle of the dust removal knife refers to the angle between the back of the knife and the horizontal plane of the frame, which is generally adjusted at 70 in production.°to 110°between. The angle is related to airflow at the back of the knife and airflow recovery at the inlet of the small drain. The distance between the dust removal knife and the drum of the carding machine is generally 0.31-0.43nun.
In production. If the spacing is too large, the airflow at the distance point between the knife and the roller increases, the cotton droplets in the first impurity area decrease, and the burden on the second impurity area increases accordingly.
