Background technology
Order in train line at gather leaves of a book train line or glue, assembling machine is that signature is overlapped to the equipment of joining in order.Its working process is by gritting one's teeth extracting out from signature stack after sheet-fed or a signature clamping, being transported to afterwards next workflow again.The transmission device of existing assembling machine mainly comprises external cam, extension spring and stings pawl, and the noise of whole mechanism is large, and the gripping power of stinging pawl can not regulate, and this mechanism can not carry out corresponding transmission work for different signatures.The pawl of stinging in assembling machine transmission device is generally made as two, like this after having stung pawl longevity of service, probably there is inconsistent situation in two gripping powers of stinging pawl, and can not adjust separately one of them gripping power of stinging pawl to sting pawl consistent with another, in transmitting paper or signature, may cause damage to it like this.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, to the larger more stable torsion spring of the carrying capacity of the signature mechanism of gritting one's teeth.
The utility model torsion spring mechanism of gritting one's teeth, comprise driving device and the device of gritting one's teeth, described driving device comprises imput shaft and is fixedly set in the toothed disc in imput shaft, the described device of gritting one's teeth comprises stings pawl, be fixedly set in stinging paper wheel and being fixed on the palmula of stinging of stinging on paper wheel in imput shaft, described driving device also comprises a grooved cam, described grooved cam is fixedly located at toothed disc outside, the rotating quadrant gear that is provided with on the outside end face of described toothed disc, described sector teeth wheel end is meshed with a miniature gears, the other end is provided with rocking bar, described rocking bar is provided with Cam ball, described Cam ball be positioned at grooved cam groove and can be along concave slot sports, described groove can make Cam ball with respect to toothed disc reciprocally swinging, described miniature gears is rotating to be arranged on toothed disc and to penetrate toothed disc, on the medial extremity of miniature gears, have cavity, described lower end of stinging pawl is fixed on stings on pawl axle, upper end can along with the rotation of imput shaft with sting palmula and be adjacent to or separate, described rotating being arranged in one end of stinging pawl axle stung on paper wheel, in the rotating cavity that is arranged on miniature gears of the other end, the medial extremity of described miniature gears is fixedly connected with a torsion spring, described torsion spring set is being stung on pawl axle, the torsion spring other end is fixedly connected with a fixed block, described fixed block is fixed on to be stung on pawl axle.
The utility model torsion spring mechanism of gritting one's teeth, the wherein said palmula of stinging is made up of non-metallic material.
The utility model torsion spring mechanism of gritting one's teeth, the wherein said quantity of stinging palmula and stinging pawl is all two, stings palmula for two and is separately fixed on two side end faces of stinging paper wheel, stings pawl for two and is separately fixed at and stings the stinging on pawl axle of paper wheel both sides.
The utility model torsion spring mechanism's difference from prior art of gritting one's teeth is that the utility model torsion spring grits one's teeth imput shaft in mechanism while rotating, drive is stung paper wheel and is rotated together with imput shaft with toothed disc, Cam ball on rocking bar can be along the concave slot sports on grooved cam, because groove curve is cam face, curve has lift, pause, backhaul, pause, the variation of lift, Cam ball can drive rocking bar reciprocally swinging like this, the reciprocally swinging of rocking bar can drive again quadrant gear reciprocally swinging, because miniature gears is meshed with quadrant gear, so under the drive of quadrant gear reciprocally swinging, can there is reciprocating rotation in miniature gears, the reciprocating rotation of miniature gears can be passed to moment of torsion to be fixed on the fixed block of stinging on pawl axle by torsion spring again, sting like this pawl axle reciprocating rotation will occur, so being fixed on the pawl of stinging of stinging on pawl axle also can be around stinging pawl axle reciprocating rotation, the reciprocating rotation of stinging pawl realized with the interlock of stinging palmula with separate.Signature is clamped when stinging palmula interlock when stinging pawl, nipped signature continues along with imput shaft rotation afterwards, in the time arriving next flow process, stings pawl and stings palmula and separate, and paper or signature are transported to next flow process.As can be seen here, the utility model is simple in structure, more stable more greatly to the carrying capacity of signature.
The utility model torsion spring is grited one's teeth and is stung palmula in mechanism and be made up of non-metallic material, like this in the time stinging pawl and signature is hauled out from signature stack come, can avoid stinging the damage that pawl causes signature and can reduce the wearing and tearing of stinging paper wheel surface.
The utility model torsion spring quantity of stinging palmula in mechanism and stinging pawl of gritting one's teeth is all two, stings like this pawl in the time that signature is hauled out from signature stack, and the snap-in force of stinging pawl is larger, also more steady.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
