Description
Technical field
The present invention relates to a kind of without head flat knitting machine yarn feed mechanism.
Background technology
Existing straight-line guide rail slide block system generally more adopts stepper motor and ball screw arrangement, and motor is fixed on guide rail one end, and slide block realizes reciprocating motion on guide rail.This kind of system accuracy is higher, generally can reach ± 0.01mm, but slide block linear velocity is generally lower than 1m/s.If increase rail length or slide block linear velocity, cost increase is higher.And this type systematic slide block cannot leave guide rail, be not suitable for the weaving requirement that flat knitting machine yarn nozzle needs odd jobs to change.
Conventional computer straight-bar machines is with head reciprocating motion, makes the knitting needle within the scope of braiding promote move up and down and drive the reciprocating motion of yarn mouth to complete braid movement through triangle.Then directly promoted braiding by linear electric machine or stepper motor without head cross weaving needle, therefore its yarn mouth also need by independently driving mechanism driving.This device will complete yarn mouth replacing action moving to without head flat knitting machine yarn nozzle guide rail end points place, and selectively the yarn mouth of needs can be placed on the endpoint location of guide rail, starts the yarn feeding process of a new round.
Positioning accuracy request due to flat knitting machine yarn nozzle is not high generally at ± about 0.5mm, but portable cord rate request is at about 1.2m/s.The present invention utilizes the integrated design of small type stepping motor and yarn mouth, utilizes pinion and rack Direct driver yarn mouth in guide rail movement fast.Although there is fit clearance in pinion and rack, reciprocating motion can cause repetitive positioning accuracy to reduce, but yarn mouth is after each single way motion completes in this device, by yarn mouth more changing device by its getaway, next time braiding time at the start position placing back in guide rail end.Therefore in each single way motion, yarn mouth position can not go out accumulated error, and its positioning precision is determined by stepper motor opened loop control precision, easily can reach ± the positioning accuracy request of 0.5mm.Speed can reach 1.2m/s-1.6m/s, and cost performance is higher.
The yarn mouth of existing Computerized flat knitting machine need drive reciprocating motion by frame head apparatus, is to be parked on fixing guide rail, can not realize the conversion process of yarn mouth between different guide rail.The straight-bar machines of general four guide rails there is 8-16 yarn mouth.
This device utilizes revolution yarn storage to take inventory and puts yarn mouth, and single yarn storage dish can deposit 6-12 mouth, and yarn storage dish is connected with slide block by connecting rod, slide block moves on the guide rail of C type, it is fluted and by magnechuck gripping band yarn mouth slide block in yarn storage dish, change between many guide rails.
Summary of the invention
In order to overcome defect of the prior art, the invention provides one without head flat knitting machine yarn feed mechanism, it is characterized in that comprising two yarn mouth drive units and whirligig be arranged in parallel,
Described yarn mouth drive unit comprises, yarn feeding mouth, drum beam, tooth bar, slide block and stepper motor, described yarn feeding mouth is connected with slide block, described slide block is positioned on drum beam, this slide block is provided with stepper motor, described tooth bar is positioned at the periphery of drum beam, and the gear of this tooth bar and stepper motor is meshed, by the rotation of tooth bar thus band movable slider slide on drum beam;
This whirligig comprises yarn storage dish, guide rail and the second slide block, and described second slide block is positioned at the central authorities of yarn storage dish, and is connected with guide rail, and this second slide block along slide, described yarn storage dish can have groove;
Described whirligig is positioned at the two ends of the yarn mouth drive unit that two be arranged in parallel, by the groove gripping slide block on yarn storage dish, thus drives yarn feeding mouth to change on two drum beams.
Described yarn feeding mouth is positioned at the below of slide block.
Described drum beam can have multiple slide block.
Beneficial effect:
Structure of the present invention is simple, reasonable in design, easy to operate, the yarn mouth of each band slide block has a stepper motor, realizes the outspoken line of yarn and move back and forth.There is high practicality.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation:
Fig. 1 is structural representation of the present invention.
