Linear tooth surface performance: It can meet the requirements of carding process, and it is convenient to process and manufacture. Scope of application: ordinary production card drum, high-count card drum, double-fold line working surface (negative angle at the bottom) Performance: working and upper are positive angles a. It has the ability to grab fractions, and the lower part has a negative angle, which can prevent the fiber from sinking, making it easy to float on the needle tip, improve the combing effect, and reduce the volume between the lower teeth, which is good for transmission, but not conducive to uniform Mixing action, application: High-yield carding machine (large cylinder) metal clothing, double-fold line convex back Performance: While maintaining the strength of the tooth tip (tooth angle), a large interdental volume is obtained, which is convenient for solidification, carding and mixing. 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. 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.
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. Application: Small cylinder high-yield carding machine, cylindrical card clothing, doffer card clothing, arc back performance: The function is similar to the double-fold line convex back tooth, when the working angle is small, the fine effect on the tooth tip is more significant, and the release ability is further improve.
When the tooth tip wears excessively, the tooth tip cotton opportunity increases rapidly, reducing the sharpness of the tooth tip. Scope of application: Cotton-type high-yield carding machine (large) cylinder metal card clothing, concave back performance: Improve the sharpness of the tooth tip, which is conducive to puncture carding; can increase the intersection capacity, scope of application: Carding chemical fiber card clothing (small working angle, Double fold line, negative angle) deep and shallow tooth surface performance: vertical spacing arrangement, away from low teeth. The high teeth have a moderate working angle and deep grooves, which are good for carding and fiber absorption, and the low teeth have a large working angle.
The alveolar depth is small, which facilitates the migration and release of fibers. The high and low teeth not only keep the fibers combed, but also reduce damage to the medium and long fibers.
