Description
Technical field
The present invention relates to a kind of accurate length control device of rove of Speed frames, belong to cotton spinning machinery technical field.
Background technology
Speed frames are one of important procedure machinery in cotton spinning engineering, but the rove ingot produced of existing Speed frames every only between length uneven, differ tens of rice, after impact, operation is produced, and causes significant wastage.The full yarn of Speed frames stops, and should accomplish " three is fixed ", i.e. fixed length, location, orientation: rove length certain when must reach when fixed length refers to spun rove ingot full yarn, be convenient on the fine spining machine of next process, carry out pagoda fragmentary works method or whole change yarn; Location refers to that the position being elevated rail residing when doffing is certain; The direction being elevated rail motion when orientation refers to and doffs is certain.The conveniently operation of creeling on fine spining machine, 1/3-1/2 At The Height that the lifting rail of General Requirements Speed frames drops to package doffs, domestic Speed frames now all adopt the electric contact be elevated with rail to start full yarn automatic stop arrangement, during normal spinning, though this electric contact touches travel switch with rail lifting and connects circuit, but because of the spindle turning around rove do not turn around full yarn time, the make and break contact of the long table of meter disconnects, so circuit is obstructed, when being namely commonly called as " full yarn " when spindle turns around full rove, length-counted device sends " full yarn " signal, full packages signal lamp is bright, the then circuit ON of contact travel switch, make main motor and the stall of air draught motor of Speed frames, start automatic doffing mechanism simultaneously.If but when length-counted device sends full yarn signal, lifting rail is not when being the position being in contact, and rail still moves, and spindle continues around yarn, just to doff parking until lifting rail touches travel switch.The meter length of such Speed frames and the different length inaccuracy making rove of parking spot, general error is at 40 meters to 70 meters, individual other can reach more than 100 meters, these uneven tens of meters of rove are commonly called as " soft end ", can make troubles to following process and must slice off, " soft end " that slice off, though recyclable for secondary board yarn production after special equipment process, the more wastes of " soft end " yield be larger, finally cause the cost up of cotton yarn manufacturing enterprise, benefit reduces.Such as Siro-spun yarn-SEILE textile is the draw zone being fed fine spining machine by two rove bars at regular intervals, resultant yarn is twisted respectively after drawing-off, when two rove length there are differences, after a rove spins sky, another rove must be taken away by tender, but for middle coarse yarn, sub-thread is run when the non-Timeliness coverage of tender, also broken end is there will not be when tension stability, major part one-ply yarn can go out from the operation sheet that falls at spindle, but also have a small amount of one-ply yarn and flow into final products, cause substandard products to affect product quality.
Summary of the invention
For overcoming the above-mentioned defect of existing Speed frames length control device, the object of this invention is to provide the accurate length control device of a kind of Speed frames, in order to realize Speed frames precise fixed-length, make the cotton yarn ingot length produced equal, solve above-mentioned Speed frames loss large, the difficult problem that productivity effect is low, production cost is high.
