The front upper shroud transfers the fibers from the flat card needles to the surface of the barrel. 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.
Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. 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 distance between the front upper cover and the Jinlin directly affects the amount of the chopper.
If the plan is large, a large number of choppers; such as a small sum, a small number of cutters cut flowers. When the distance between the front upper cover plate and Xinjinlong increases, not only does the cutting knife flower rate increase, but also the cutting knife flower mainly contains more fine fibers and fibers. If the front upper cover plate is removed, the A very thick cotton will gradually form. The distance between the front cover and Xinjinlong is generally arranged such that the distance between the upper openings is small and the distance between the lower openings is large.
The following spacing is generally used: the upper opening spacing is 0.43-0.84mm (17/1000-33/1000 inches), and the lower opening knob is 0.79-1.09mm (31/1000-43/1000 inches). When using type 702 or type 672 flat card clothing, the gap between the upper openings should be increased due to the weak ability of the needle teeth to grasp the fibers. If the cover is still broken or does not come out, the upper clearance of the front cover should be larger than the lower clearance.
The position of the top of the front upper cover can be determined by inserting the width of the Xinjinlong cover to determine the location of fiber cell transfer, which also has a certain impact on the quality of the transfer and the flower rate of the cover. When the upper end of the upper cover is inserted into the Xinjinlong cover, the fibers on one cover can be easily developed and transferred to the reinforced Xinjinlong, thereby reducing the cutting rate. For example, when the distance between the upper end of the front upper cover and the center line of the cover arc is reduced from 22 mm to 16 mm, the cutting rate can be reduced by about 15%.
Therefore, if necessary, the front upper cover can be lengthened. The distance between the carding machine Xinjinlong and the bottom of the front cover is generally configured as the upper gap and the lower gap. When the lower seam is large, the fibers on the cylinder will be transferred to the doffer, but if the lower seam is too large, it will cause cloud spots on the cotton net and increase the evenness of evenness.
The following gauges are commonly used: The upper gauge is 0.79-1.09 mm (31/1000 r-43/1000 inches) and the lower opening is 0.43-0.66 mm (17/1000-26/1000 inches).
