Single-axis positive yarn feeder for computerized flat knitting machine
Technical field
The present invention discloses a kind of Computerized flat knitting machine yarn feeder, divides by International Patent Classification (IPC) (IPC) to belong to Computerized flat knitting machine yarn-feeding device class manufacturing technology field, especially relates to a kind of single-axis positive yarn feeder for computerized flat knitting machine device.
Background technology
Computerized flat knitting machine is a kind of knitting device loom, its triangle device is just as one group of plane cam, the stitch of knitting needle can enter in the conduit of cam, movable triangular, force knitting needle in the needle tray of needle plate, to do regular elevating movement, and collude action with needle latch by pin, just yarn can be woven into knitted fabric.In sending yarn or yarn feeding process, existing yarn feeder is when transmitting yarn, because yarn has rubbing action with the yarn-feeding roller surface, and then the generation resistance, particularly in the multi-thread situation of sending yarn, its resistance is larger, has influence on braid efficiency and quality.
As yarn feeder, such as the disclosed yarn feeder structure of Chinese patent literature CN2275102Y, be in fact the function of taking on yarn storage in the prior art, yet in actual use, the yarn mode of sending of this yarn feeder is the passive yarn that send, and yarn tension is difficult to control and some yarn easy fracture.China Patent Publication No. CN201546010U discloses a kind of yarn feeder, and as shown in Figure 1, motor C drives the first conveying roller A and the second conveying roller B, and finishes in conjunction with other accessories and to send the yarn operation.
The inventor is through studying for a long period of time and in conjunction with being engaged in knitting industry experience for many years, creating one and send yarn stable Novel yarn-feeding device.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of rational in infrastructure, send yarn uniform and stable single-axis positive yarn feeder for computerized flat knitting machine, this device can effectively reduce the yarn resistance, and can control the tension force of stablizing yarn.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of single-axis positive yarn feeder for computerized flat knitting machine, comprise drive motors, transmission case and band yarn roller, described band yarn roller is one, it is installed on the transmission case and by the belt transmission in the transmission case and is connected with the output of drive motors, described transmission case side is provided with yarn withdrawal plate, several equally spaced draw-in groove thread-carriers are installed on this yarn withdrawal plate and are cooperated to finish with band yarn roller and send the yarn operation, described band yarn roller surface uniform coating titanium oxide layer, its smooth surface, antistatic are not hung fiber.
Further, described band yarn roller is hollow structure, and along its central shaft to wearing band yarn roll shaft, band yarn roller one end is fixed on the transmission case and support belt yarn roller, and the other end cooperates to limit band yarn roller with end cap, and band yarn roller can relatively rotate with band yarn roll shaft.
Further, described plating titanium oxide layer thickness with yarn roller surface is 0.3mm, and this is provided with the annular groove that the degree of depth is 2mm with yarn roller stiff end, and this annular groove is comprised of ring-type arc groove and upwardly extending two inclined-planes.
Further, make up by bearing and band yarn roller respectively at described band yarn roll shaft two ends, and be provided with balancing patch near band yarn roller external port, and this balancing patch is positioned at the end cap inboard.
Further, described transmission case bottom surface connects a support arm, is provided with vibration damping sheet between itself and transmission tank wall, and the supporting walls tail end is installed the support ear piece.
The present invention includes single shaft band yarn roller, its yarn guide member with a side cooperates for the head yarn of the yarn of drawing on the drum on the taking-up frame being delivered to the knitting mechanism of flat machine to be chewed, the utility model is designed to the active yarn transmission mode with the passive yarn that send, make yarn through thread-carrier and with being in the constant yarn speed of sending behind the yarn roller, and the lubricious design with the yarn roller, reduce the resistance in the yarn course of conveying, band yarn roller surface spraying pottery, antistatic, wear-resisting, adopt the polywedge bet transmission, steadily, durable, the multi-thread optimum device that send yarn, can Effective Raise braid efficiency and weaving quality.
The present invention can improve and send yarn quality, reduces the yarn resistance, improves the braiding aesthetic of Computerized flat knitting machine fabric.This product has simple in structure, and is with low cost, the advantage with promoting easy to use.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Embodiment: see also Fig. 2 to Fig. 4, a kind of single-axis positive yarn feeder for computerized flat knitting machine, comprise drive motors 1, transmission case 2 and band yarn roller 3, described band yarn roller 3 is one, it is installed on the transmission case and by belt 4 transmissions in the transmission case 2 and is connected with the output of drive motors 1, described transmission case side is provided with yarn withdrawal plate 6, several equally spaced draw-in groove thread-carriers 7 are installed on this yarn withdrawal plate 6 and are cooperated to finish with band yarn roller and send the yarn operation, described band yarn roller surface uniform coating is thick to be 0.3mm titanium oxide layer 32, and its smooth surface, antistatic are not hung fiber.
See also Fig. 2, band yarn roller 3 of the present invention is hollow structure, along its central shaft to wearing band yarn roll shaft 8, band yarn roller one end is fixed on the transmission case and support belt yarn roller, the other end cooperates to limit band yarn roller with end cap 9, and band yarn roller can relatively rotate with band yarn roll shaft, describedly is provided with the annular groove 31 that the degree of depth is 2mm with yarn roller 3 stiff ends, and this annular groove is comprised of ring-type arc groove and upwardly extending two inclined-planes.Make up by bearing and band yarn roller respectively at described band yarn roll shaft two ends, and be provided with balancing patch 10 near band yarn roller external port, and this balancing patch is positioned at the end cap inboard.Described transmission case bottom surface connects a support arm 11, is provided with vibration damping sheet 12 between itself and transmission tank wall, and the supporting walls tail end is installed support ear piece 13.
See also Fig. 3, transmission mechanism of the present invention is belt transmission, and belt 4 one ends are connected in the output pulley end of drive motors, and the belt other end is connected in band yarn roller, and transmission case is comprised of casing 21 and upper end cover 22.
Fig. 5 to Figure 10 has enumerated respectively three kinds and has worn method for winding, specifically sees diagram arrow trend, and wherein inlet wire and outlet must be staggered a thread-carrier porcelain eye in case wrap wire among Fig. 5 and Fig. 6.
The utility model can exchange with the smart machine in island, and imported bearing is simple in structure, durable in use, and yarn roller plating pottery can reach the 6000r/min rotating speed, send yarn respond well.The present invention is lower than yarn storage device price, and effect is better than yarn storage device, guarantees to send yarn even, and dropped stitch is not knitted the sheet even tissue, can reduce and the tension force of stable yarn, makes and send yarn more even, and fabric is more attractive in appearance.Yarn-feeding roller in the yarn feeder adopts super wear-resistant ceramic, through attrition process, has the characteristics of the durable practicality of antistatic, adopts German imported bearing, and motor is through the low vibration of low temperature, and the long-life design determines that whole yarn feeder is reliable and stable.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
