Opening machine forming mechanism

     The forming mechanism of the opening machine is composed of a bell mouth, a pressing roller, a coiler, a sliver drum, a chassis and a transmission mechanism. The function of the forming mechanism is to take the cotton net output by the collecting roller through the bell mouth and press tightly. The compression of the rollers becomes a fine strip with a certain density and tension, and then passes through the slits of the strips, and is regularly arranged in the street again and again.

     The size of the bell mouth of the opener is selected according to the quantitative of the ladder. The heavier the sliver, the larger the caliber of the bell mouth. If the feeding diameter of the bell mouth is too large, the shrinkage effect of the cotton net is not ideal, the cotton sliver is easy to fluff, and the diameter of the bell mouth is too small, and accidental drafting may occur when the cotton net passes through. The diameter of the bell mouth of the final draw frame should be 0.2 mm smaller than that of the first draw frame, so that the shrinking sliver can be compressed by one step.

     The opener pressing roller is a pair of metal rollers with smooth surface. The front pressure roller is in close contact with the back pressure roller by the spring. Relying on the spring action of the pressure roller and the weight of the pressure roller itself, the noodles are subjected to a certain pressure when they pass, thereby increasing the density of the fine strips and reducing The sliver is fluffy and sticky. Due to its compactness, the capacity of the sliver in the elliptical sliver can be refined, and the strength of the sliver can be lifted away, reducing accidental stretching and end breakage in the next process.

      Zhou Tiao is also known as Quan Tiaolong. The coiler is composed of a chassis, a housing, an inclined tube and other components. The cotton sliver is output by the pressing roller, and is fed into the Kam Tiao Street meat through the inclined tube of the chaff. The role of shed chaff mainly plays the role of conveying and forming.
