Below by a concrete operations example characteristics of the present utility model are described:
With reference to Fig. 2-4, reducing motor 20 starts, and reducing motor 20 main shafts drive crank wheel 34 left-hand revolutions, and rocking bar wheel 32 rotates under the drive of connecting rod 33; Before crank wheel 34 turns over during half cycle, rocking bar wheel 32 turns to the left-limit position, in this process, power is passed on the gear transmission group in the gear case 40 by unilateral bearing 35, synchronous pulley I 31, synchronous pulley II 41 successively, give two conveying rollers 51 by coupler 42 with power distribution by the gear transmission group, make it drive strap 9 and travel forward; When crank wheel 34 when turning over second half, rocking bar wheel 32 turns to the limit on the right-right-hand limit position, in this process, the outer ring 352 of unilateral bearing 35 does not rotate, thereby power can't be passed to gear case 40, conveying roller 51 stops to carry strap.Said process is to have utilized quadric linkage 3 to realize the feed motion of strap.
With reference to Fig. 5, the cutting action of the cutting blade 82 that carries out synchronously with the strap feed motion: reducing motor 20 main shafts have also driven synchronous pulley III 61 and have rotated counterclockwise when driving crank wheel 34 left-hand revolutions, power is passed on the transmission shaft 70 by synchronous pulley IV 62, reverse wheel 72 beginnings make driven member 71 axially produce crank motion at transmission shaft 70 along commutation groove 73 orbiting motions, what this motion was concrete can be divided into following three steps: 1, reverse wheel 72 at first begins walking from zero-bit groove 731, because zero-bit groove 731 is parallel with the strap throughput direction, driven member 71 can not produce longitudinal travel, so also just avoided strap in motion forward, to move interference with cutting mechanism 8, prevent damage equipment, waste raw material; 2, reverse wheel 72 is covered zero-bit groove 731 and is entered forward groove 732, forward groove 732 is to strap throughput direction deflection, when therefore reverse wheel 72 was along 732 walkings of forward groove, driven member 71 can produce the displacement of forward, and then 8 pairs of straps of promotion cutting mechanism cut; 3, reverse wheel 72 is covered forward groove 732 and is entered negative sense groove 733, forward groove 732 is away from the strap throughput direction, and when reverse wheel 72 was walked along negative sense groove 733, driven member 71 can produce the displacement of negative sense, and then make cutting mechanism 8 be retracted into original position, and reverse wheel 72 reenters zero-bit groove 731.
Zero-bit groove 731 is long according to the delivery speed design-calculated of conveying roller 51; Forward groove 732 is not influencing on the cutting mechanism basis of 8 integral reset times, and its angle excursion design-calculated is bigger, can accelerate the Feeding speed of cutting blade 82 like this, reduces heat and produces, and improves the life-span of cutting blade 82; And negative sense groove 733 can be regarded as forward groove 732 is a mirror image of center line with zero-bit groove 731.
To sum up, after reducing motor 20 starts, conveying mechanism 5 is realized the interval property conveying of strap, cutting mechanism 8 then periodically cuts feed motion under the effect of reverse drive mechanism 7, in order to guarantee work efficiency, the interval time of delivery of conveying mechanism 5 and commutation cycle equate because of keeping, be exactly that conveying mechanism 5 is when finishing a strap conveying in simple terms, reverse wheel 72 is just in time covered commutation groove 73, be that cutting blade 82 reaches are cut straps once, rollback then waits for that conveying mechanism 5 carries strap once more.But meaning of the present utility model not only is to realize the automatic cutting of strap, the more important thing is the quality that guarantees the packing button, because the cutting action of the feed motion of strap and cutting blade 82 meets at right angles, also just said so from the widest part cutting past of strap, thereby solved the irregular difficult problem in packing button cross section in the prior art, solved the problem that a plurality of specifications are arranged with batch packing button length simultaneously.
Except that above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
