Description

Certificate puncher of mistake proofing position

Technical Field

The invention relates to the technical field of punching mechanisms, in particular to a dislocation-preventing voucher punching machine.

Background

Accounting documents are the basis of entering accounts and accounting, and generally need to be bound into a book for storage according to months, the traditional binding method generally uses a awl hole and then stitches the awl hole, but when the awl hole is used for binding, the labor intensity is high, the binding efficiency is low, and meanwhile, the documents are easy to damage.

In order to facilitate punching and binding of the voucher, chinese patent publication numbers are as follows: the utility model of CN209007711U provides a punching device for accounting documents, which comprises a base, a punching mechanism, a lead screw, a slide block and a scrap removing needle; the punching mechanism is provided with a pressing mechanism; a return spring is arranged on the pressing mechanism; a sliding plate is arranged on the base; the chip removing needle is fixed on the base and penetrates into the punching needle of the punching mechanism; the utility model solves the defect that the prior perforating machine does not compress the file in real time when perforating, and prevents the file from dislocation when perforating; the utility model discloses a remove the bits needle and remove the bits at any time and guaranteed that the perforating needle can not block up, need not clear up the interior wastepaper of perforating needle after punching many times.

Among the above-mentioned voucher puncher, through hold-down mechanism's setting, though can be effectual compress tightly a plurality of vouchers, prevent the voucher dislocation, nevertheless in practical application we discover that it still has certain weak point, for example:

when the pressing mechanism is used for pressing independently, the pressing effect is still insufficient, the periphery of the certificates is lack of positioning, relative movement is easy to occur among the certificates of multiple layers, and particularly when the pressing mechanism is just contacted with the certificates of the upper layer, the certificates of the upper layer are dislocated due to uneven stress or inconsistent contact time and the like;

based on this, we propose a certificate puncher that is resistant to misalignment.
