Abstract
The invention discloses a rotary untwisting mechanism of a weft yarn bobbin, which comprises a frame, a weft yarn bobbin and a yarn carrier positioned above the weft yarn bobbin, and is characterized by also comprising at least one yarn bobbin rotary table which is used for placing the weft yarn bobbin; the yarn bobbin rotary table is provided with a rotary table actuating unit; the yarn bobbin rotary table drives the weft yarn bobbin to rotate; and the weft yarn bobbin is kept still relative to the yarn bobbin rotary table. When a flat cross-section filament is used as weft yarn, the weft yarn is untwisted when sequentially unreeling from the weft yarn bobbin. The invention can effectively overcome the phenomenon of severe twisting in the prior art when a flat cross-section filament is used as weft yarn, and is beneficial to the quality improvement of plastic fabrics, such as plastic tarpaulin and the like.
Description
Technical field
The weft yarn that the present invention relates to water jet looms provides part, and particularly a kind of weft yarn of plastic knitting cloth water jet loom provides part.
Background technology
Plastic knitting cloth water jet loom process structure of the prior art mainly contains parts such as shedding mechanism, water jet weft insertion device, beating-up mechanism, warp-feeding mechanism, spooler and other auxiliary bodies, and other auxiliary bodies can comprise that weft yarn provides part, measuring motion, storage Weft handling device, selvage device and Warp stop motions etc.Its groundwork principle roughly is: drive the upper and lower motion of heald frame by shedding mechanism, make plastics silk thread form shed open as warp thread, weft insertion device will be brought shed open into as the plastics silk thread of weft yarn by water jet, drive weft yarn that reed will enter shed open by beating-up mechanism then and squeeze into fell and be woven into plastic woven cloth.Above-mentioned weft yarn provides part to comprise weft yarn tube and the fixed disk of placing the weft yarn tube, the weft yarn tube passes upright tube axle on the fixed disk and places fixedly on the card, in the wefting insertion process, weft yarn is docile and obedient the preface unwinding from the weft yarn tube and is got off, by the thread-carrier of top, with yarn around to the fixed length dish of rotation, through survey long after, carry the input shed open by water jet, finish wefting insertion.Above-mentioned weft yarn provides part when using the cylindricality weft weaving, can make fabrics cloth cover keep smooth.But at plastic braids such as production Plastic awning cloths, will there be such phenomenon when using flat filament as weft yarn, that is: in the wefting insertion process, there is serious twisting phenomenon during the order unwinding in the thread-carrier of weft yarn by the top from the weft yarn tube, cause the twisting of weft yarn curl, the weft yarn of this state is dropped into shed open after storing up latitude, fixed length, beat up through beating-up mechanism, the fabrics cloth cover utmost point out-of-flatness that is made into, plastic braid qualities such as the Plastic awning cloth of producing are low.
Summary of the invention
The weft yarn that task of the present invention is to solve plastic knitting cloth water jet loom in the prior art etc. provides part existing technological deficiency, and a kind of weft yarn tube rotation loose twist mechanism is provided.
Its technical solution is:
A kind of weft yarn tube rotation loose twist mechanism comprises frame, weft yarn tube and is positioned at the thread-carrier of weft yarn tube top that also comprise at least one yarn tube rotating disk, a yarn tube rotating disk is used to place a weft yarn tube, and yarn tube rotating disk disposes the rotating disk actuating unit.
Above-mentioned yarn tube rotating disk carries weft yarn tube rotation, and maintenance is relative static between weft yarn tube and the place yarn tube rotating disk.
The central part of above-mentioned yarn tube rotating disk is provided with upright tube axle, and the weft yarn tube passes the tube axle and is sitting on the card of yarn tube rotating disk; The card of above-mentioned yarn tube rotating disk is provided with the annular stop holddown groove of inserting for the bobbin bottom of weft yarn tube.
Above-mentioned rotating disk actuating unit comprises motor, and motor is corresponding one by one with yarn tube rotating disk; Motor be positioned at yarn tube rotating disk under, motor is suspended on the motor fixed disk that is positioned on the frame, motor shaft is connected with the power transmission shaft that is positioned at the top by shaft coupling, and power transmission shaft is fixedly connected on the motor fixed disk by bearing block, and power transmission shaft is connected with the yarn tube rotating disk that is positioned at the top.
Above-mentioned yarn tube rotating disk has two, and one of them yarn tube rotating disk is in current running status, and another yarn tube rotating disk then is in SBR, and the state of the two can alternately be changed.
The rotary speed of above-mentioned yarn tube rotating disk, suitable with the needed weft yarn of the filling insertion rate of water jet looms speed of unwinding from the weft yarn tube.
The present invention has following useful technique effect:
The present invention is owing to be provided with yarn tube rotating disk, yarn tube rotating disk disposes the rotating disk actuating unit, in water jet looms wefting insertion process, drive the corresponding rotation of yarn tube rotating disk by control rotating disk actuating unit, carry the rotation of weft yarn tube by yarn tube rotating disk, such as the rotary speed that makes yarn tube rotating disk, suitable with the needed weft yarn of water jet looms filling insertion rate speed of unwinding from the weft yarn tube, like this when using flat filament as weft yarn, weft yarn when the weft yarn tube is docile and obedient the preface unwinding by loose twist, can overcome in the prior art weft yarn effectively provides part existing serious twisting phenomenon when using flat filament as weft yarn, helps improving the quality of plastic braids such as Plastic awning cloth.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and the specific embodiment:
Figure is the structural principle schematic diagram of one embodiment of the present invention.
The specific embodiment
In conjunction with the accompanying drawings, a kind of weft yarn tube rotation loose twist mechanism comprises frame 1, weft yarn tube 2 and is positioned at the thread-carrier 3 of weft yarn tube top.Above-mentioned weft yarn tube rotates loose twist mechanism and comprises that also 4, one yarn tubes of at least one yarn tube rotating disk rotating disk is used to place a weft yarn tube, and yarn tube rotating disk disposes the rotating disk actuating unit.This example is selected a yarn tube rotating disk for use, above-mentioned rotating disk actuating unit comprises a motor 5, motor be positioned at yarn tube rotating disk under, motor is suspended on the motor fixed disk 6 that is positioned on the frame, motor shaft is connected with the power transmission shaft 7 that is positioned at the top by shaft coupling, power transmission shaft 7 is fixedly connected on the motor fixed disk by bearing block 8, and power transmission shaft is connected with the yarn tube rotating disk that is positioned at the top.The central part of above-mentioned yarn tube rotating disk is provided with upright tube axle 9, and the weft yarn tube passes the tube axle and is sitting on the card of yarn tube rotating disk; The card of above-mentioned rotating disk is provided with the annular stop holddown groove 10 of inserting for the bobbin bottom of weft yarn tube.Above-mentioned yarn tube rotating disk carries weft yarn tube rotation, and maintenance is relative static between weft yarn tube and the place yarn tube rotating disk.The rotary speed of above-mentioned yarn tube rotating disk 4, preferably suitable with the needed weft yarn 11 of the filling insertion rate of water jet looms speed of unwinding from the weft yarn tube; Certainly, also other selections can be arranged,, do not twisted when making the weft yarn unwinding, or twisting degree alleviates and gets final product as long as yarn tube rotating disk carries weft yarn tube rotation.
