Description
Technical field
The present invention relates to the single thread control device of computer-shape jacquard warp.
Background technology
Generally on the two-needle bar jacquard warp, weave at present at seamless formed product.The two-needle bar jacquard warp has last lever jack, middle lever jack and following lever jack; The yarn that gets off from coiled hair successively last lever jack, lever jack and following lever jack surface slide; In this process, yarn gets into knitting needle through separating needle on the lever jack in being fixed on and the spring tension sheet that is fixed on down on the lever jack.The two-needle bar jacquard warp is in when braiding, and forward and backward needle-bar respectively forms a slice fabric, and the dual-side yarn that being connected of anter and back sheet is forward and backward is respectively through merchant's card pin skew realization; Because the dual-side yarn moving law that connection is forward and backward and the moving law of other warp thread are inconsistent; Need the yarn of consumption different,, cause the limit yarn tension different with the tension force of other warp thread sending under the identical condition of footpath speed; Usually the limit yarn tension is less than the tension force of other warp thread; Though the spring tension sheet has certain compensating action, can not adjust and send footpath speed, can not adapt to the adjustment of opposite side yarn tension; So still produce the slit forward and backward junction easily, influence the quality of product.In addition when knitting big mesh or the technology of the continuous little thread-feeding amount of continuous little mesh when organizing, owing to offer the yarn amount of mesh technology tissue and the yarn amount of other normal process tissue is identical, and the yarn amount that mesh technology tissue is consumed is little; Make the tension force of yarn at mesh position reduce like this; Thereby produce the phenomenon that mesh can not open, it is unclear to cause blank colored pattern to stick with paste, and influences appearance of fabrics; Especially be the sandwich jacquard fabric for two-needle bar interval jacquard fabric, particularly outstanding.
Summary of the invention
The objective of the invention is to propose a kind ofly to send the footpath computer-shape jacquard warp single thread control device that speed is adjusted the tension force of single thread through adjustment.
For achieving the above object, the present invention takes following technical scheme.
The single thread control device of this computer-shape jacquard warp comprises last lever jack, weight transmitter, adjuster and the sliding seat of warp knitting machine; Said sliding seat can move on last lever jack; Between sliding seat and last lever jack, lock screw is set; The sensor of said weight transmitter is fixed on the sliding seat, and is fixed with the sensing roller on the sensor, and said adjuster has servomotor and the roller support that is fixed on the sliding seat and is connected the active rubber roll tube on the roller support and is pressed in the floating rubber roller on the active rubber roll tube; The active rubber roll tube also is provided with respectively preceding guide roller and back guide roller by the servomotor driven rotary on the sliding seat; Single thread passes through between active rubber roll tube and floating rubber roller; The downside surface of the uper side surface of the downside surface of guide roller cylinder, sensing roller cylinder and back guide roller cylinder forms circuitous moving before pasting; The weight transmitter sensor acquisition to weighing-up wave after conversion, be transported to computer, adjust warp run-in by the rotating speed of computer regulated servomotor.
The upper end of said sliding seat is connected with the bobbin support.
Said going up on the lever jack is fixed with slide rail; The lower end of said sliding seat has the chute that cooperates with the slide rail of last lever jack; On the bottom land wall of chute, be provided with screw hole on the sliding seat; On the slide rail of last lever jack, be provided with the bar groove, said lock screw is connected with nut with the bar groove of slide rail through the screw hole on the sliding seat.
Said sliding seat is formed by connecting main part and connector, on connector, is provided with two raised lines, forms said chute between two raised lines.
Respectively be provided with dead eye in said roller support biside plate bottom, respectively be provided with clutch shaft bearing in the two bearings hole, said active rubber roll tube is supported by above-mentioned two clutch shaft bearings.
Biside plate top at said roller support respectively is provided with opening, respectively is provided with the slide block of slippage up and down in two openings, respectively is provided with dead eye on two slide blocks, respectively is provided with second bearing in the two bearings hole, and said floating rubber roller is by above-mentioned two second bearings.
Respectively be provided with gathering sill on the two relative walls of said each opening, the slide block in each opening moves along two gathering sills on wall.
Said roller props up corresponding each slide block of top of the trellis and is provided with screw hole, is provided with adjustment screw in the screw hole, is provided with spring between every adjustment screw and the corresponding slide block.
Be connected by belt gear between the main shaft of said servomotor and the active rubber roll tube.
Be connected by shaft coupling between the main shaft of said servomotor and the active rubber roll tube.
The present invention has following good effect: 1, this device is provided with the weight transmitter; The weight transmitter sensor acquisition to the treated computer that is transported to of single yarn tension signal; Rotating speed by the computer regulated servomotor is adjusted warp run-in, thereby reaches the effect of adjustment single yarn tension.2, because the sliding seat of this device can slide,, a plurality of devices can be set on warp knitting machine on last lever jack, simultaneously many single thread be carried out tension adjustment so can adapt to the tension adjustment of diverse location single thread.Single thread can be provided by the bobbin that is arranged on this device, also can directly be provided by coiled hair.3, this device uses easily, as long as get into merchant's card knitting needle to the single thread of need adjustment tension force through passing separating needle and spring tension sheet behind this device again.4, in this device, the fluctuating of floating rubber roller, and, adapt to the single thread of different thicknesses through the pressure of adjustment screw adjustment spring to the active rubber roll tube, the adjusting to single yarn tension simultaneously plays certain function, prevents broken yarn.5, this device has solved because of the tension force of limit yarn loosely excessively well, causes forward and backward of seamless formed product to connect the problem that produces the slit, can prevent simultaneously to play destruction because of the high strung of the tension of single thread blocks knitting needle to the merchant of warp knitting machine.When the technology that to knit big mesh or continuous little mesh be continuous little thread-feeding amount is organized; Can guarantee that corresponding several yarns adopt suitable tension force; Mesh can be strutted; Guarantee the clear of blank colored type,, can weave at the brocade table surface layer and have relief colored type clearly especially for two-needle bar jacquard fabric at interval.
