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.
