So design, is made very conveniently at design, and total is simple, understandable!
As optimization, described sliding selective gear assembly has corresponding adjusting pulling block, and this adjusting pulling block is provided with N+1 positioning, and each positioning correspondence a pair of gear meshing position.So static stall is convenient in design.
The pleating machine of band dual spindle transmission of the present invention, comprise driving mechanism, slidercrank mechanism and feeding perching knife, the three connects in turn, described driving mechanism passes to slidercrank mechanism with the rotation that power source provides, changed into the to-and-fro motion of feeding perching knife again by slidercrank mechanism, it is characterized in that: described driving mechanism contains above-mentioned dual spindle transmission.
As optimization, the described feeding perching knife back side is provided with a dunnage.So design, when the feeding of feeding perching knife was advanced, dunnage provided the rigidity support for the feeding perching knife, and when the feeding of feeding perching knife retreated, dunnage did not influence the elasticity of feeding perching knife again.
As optimization, the connecting rod of described slidercrank mechanism is made of a double threaded screw and two end nuts thereof, and the nut thread at this double threaded screw and two ends thereof is opposite.So design, be convenient to regulate the horizontal terminal point of feeding perching knife, prevent that the perching knife feeding is excessive, block the sewing machine pin hole, syringe needle fractures.
As optimization, the crank in the described slidercrank mechanism is an eccentric wheel, has groove on this eccentric wheel, and described connecting rod and eccentric tie point just are fixed on the mounting blocks of this groove, and this mounting blocks is fixed in the described groove by the screw adjustable ground.So design, the horizontal motion scope of being convenient to regulate the feeding perching knife.
As optimization, described driving mechanism is made up of synchronous belt mechanism, gear mechanism, link chain mechanism and other driving mechanisms that can not skid.So design can prevent to make this pleating machine of institute lag behind because of driving mechanism skids, and causes the pleated width of getting to differ.
As optimization, this pleating machine perhaps directly matches with the flywheel of adapted seam adapted sewing machine with the shared same motor of adapted sewing machine.So design, this pleating machine and the concerted action of adapted sewing machine, no matter sewing machine is still slow soon, and institute is up to pleated all the same.
That dual spindle transmission of the present invention has is simple in structure, speed governing advantage easily, is the desirable substitute products of existing little shape gearbox, and band dual spindle transmission pleating machine of the present invention has that volume is little, in light weight, advantage of simple structure, is fit to beat the Accordion of multiple width.
