Card for processing of cotton fiber and chemical fiber, textile machinery belongs. According to the spinning process, carding is an important process. Card before the procedure is Blowroom machine, after the procedure is drawframes (carded process) or strip coiler (combing process). Works card works before the procedure is sent cotton (fiber) or from cotton tank volume of oil supplied cotton (fiber) layer opening carding and cleaning, all curly massive cotton circle as the basic straight monofilamentous, and in the process, took steps to get rid of the legacy of Qing broken seeds, impurities and short fiber, then integrate certain specifications sliver, cotton stored in the barrel, and of the process for use . Structure structure structure and composition card is divided into three parts: ① pre comb parts, including the taker, the feed roller, feed plate, knife and taker dust and other components; ② main comb parts, including the cylinder cover ③ into strip sections, including stripper roller, loudspeaker mouth, large roll and coiler and other components; plates, Astoria and large taker and other components. Feed roller surface composition principle axial straight grooves, ends with a pressurizing device. Cotton plate to the front of the arc and the feed roller with the formation of pressure jaws to facilitate gripping the cotton. Licker is a major component part of the pre-comb, embedded jagged strip of the hollow cylinder, coated, high speed. Licker beneath the dust and curved knife with a mesh or grid bar taker for holding fiber and exclude impurities and fuzz. Cylinder and doffer are hollow cylinder, coated clothing. Larger diameter cylinder is the main whole machine. Cover and cylinder are the main components of the main comb portion covers the total number of roots is generally 106 to 110, and the cylinder cover interaction of work from 41 to 43. Cover long and narrow shape, T-shape cross-section. Cover Face covering clothing, the contact surface at both ends of the support rail made of curved heel-toe arc, arc height difference of around 0.5 to 0.9 mm. Imported interacting with each cylinder gauge cover large and small export gauge, so carding effect gradually. All covers through the chain link transmission, forward rotation cycle slowly since, in turn play a role carding. Cover the work area beyond the pin surface grab fuzz, miscellaneous debris and partially spun fibers, cut knife peeled off by the cover plate and become the cover off the cotton. Rear cover return machine after cleaning and re-enter the work area, so called rotary carding machine. Great taker cylinder posted by two triangular lattice and curved dust light panels for holding fiber layer cylinder surface and the discharge portion Linter miscellaneous debris. Cylinder, gauge licker, cover, species Astoria and stripper roller surface coated clothing or saw blades, density and angle of needle teeth and between the needle surface is determined according to process requirements. Since the speed of the cylinder surface Astoria 1/15 to 1/30, part of the fiber surface of the cylinder surface is collected in Astoria, stripping roller stripping cotton fiber layer was on the surface of the transfer roller Randolph leads become webs. Upper and lower rolls hard smooth surface of small impurities defects remaining webs have some crushed scavenging. For the sliver coiler regularly sliver ring on the barrel.
