It is the specification drawing of the saw blade. In the figure, the working angle, tooth pitch P, tooth tip thickness b, base thickness W and total quotient H are the main technical specifications. Among them, P and b have the greatest influence on the carding effect. 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. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.
Card saw song and mild steel material in the past to improve hardness and wear resistance now use 45 gauge steel. The size of the abutment teeth of the cotton wool, the small working angle, the knife piercing ability, the strong penetrating ability of the working angle, but the disadvantage is too small for the garbage. From the current business point of view, the commonly used spinning cotton is 75_80.
On-site spinning also has 80-90 long fibers. of. The tooth pitch P of the carding machine is 5.644 mm (4 teeth per inch), the lateral development density of the sawtooth structure is 8 grooves per 25.4 mm, and the tooth defect density of the back IJ per (25.4 mm) is N=(25.4/5.644)x8=36 Teeth / (25.4mm) Z.
When the lateral value density of the serrations on the brocade is the same, the pitch P is a direct factor of serration or density. There are three types of tooth tip thickness b: thick, medium and thin. Generally, the thickness b of the tooth tip is less than 0.3 mm, which is called thin tooth.
Thick teeth have a tip thickness of 0.4 mm. Thin tooth piercing ability, good combing. The fiber damage is small, the ball drop rate is reduced, and the impurity rate is increased.
