Combing machine for fur is one of key equipment of wool textile enterprises, in top processing enterprise, woolen spinning factory, cashmere cotton mill, half essence It spins in enterprise and is widely used.Woolen card main function is that the hair of process or the mixing of oiling are carried out thoroughly comb pine, is made It is in single fiber shape and further mixes impurity elimination.Make to comb loose fiber simultaneously and stretch as far as possible in parallel, be eventually fabricated rounding, it is bright and clean, Compact continuous small wool top, is wound into group for wool top, convenient for storage, carries and continue to process.

Combing machine for fur developing history is long, is initially (a kind of ancient by being equipped with the pecten of inclined needle tooth on two boards face Grooming tool) be evolved.Mechanical means is gradually changed to by manual method to the combing of 18th century.1738, the Borrow of Britain used One roller with a needle constitutes the area Fen Shu with corresponding cambered surface pecten, greatly expands combing effect area.The same year, Bo En Multiple roll cylinder carding machine is created again.Later, it installs feed apron additional on this basis and strips die, realize and be continuously fed for original The function that material and reticular fibre thin layer continuously export.By 1792, Cartwright was in Britain's utility model roller and clearer card.18 There is fixed cover plate type carding machine in the end of the century.Shortly after, American Wei Erman creates the board-like carding machine of rotary cap again, solves Cotton carding problem.1810, Frenchman's hot-drawn that created roller type eckling machine.Since 19th century, roller type eckling machine has The combing system of many improvement and development, woolen card is just derived from this.

Currently, woolen card specifically includes that pre-comb machine, Principle of Auto Feeders for Wool, combing segment machine, sett frame, gap bridge machine Five parts.The course of work of combing machine for fur is: the mixing handed down from wool blending step is first sent into Principle of Auto Feeders for Wool.It quantitatively makes Mixing is by wool lifting curtain, hello hair roller and claims hair bucket, is finally sent into pre-comb machine.Mixing is by working roll and chest in pre-comb machine Cylinder Carding resolves into fibre bundle and small bulk from big bulk.Small bulk fibers are transferred to first thereafter by transport roller Carding machine.Big cylinder on first carding machine is sufficiently mixed pencil and bulk fibers with stripper roller, five pairs of working rolls Combing is loosened as single fiber, then through wind wheel from the needle gap of big cylinder out, condense upon on doffer.The road die Zai Jiang The upper fiber of husband cuts down to form fleece, is sent into the first gap bridge machine.

Subsequent fleece can on gap bridge machine by laterally folded mixing and longitudinal folding mixing, then into the second carding machine of people, Receive further to mix again, comb, is carded to single fiber shape, fleece is then formed again by wind wheel, doffer, die, Into on the second gap bridge machine.After the second gap bridge machine folds mixing, fleece, which enters, carries out last time in third section carding machine Combing.Finally from the fleece that doffer exports, the degree of stretching and orientation of fiber are all relatively high.Fleece is fed into sett frame. In sett frame, fleece is cut into several small hair-videotapes by leather lacing, finally passes through four pairs of washboards, and afterturn is at bright and clean, rounding, tight The small wool top (i.e. rove) caused, and it is wound into rove hair cake.
