Paper feeding and positioning device for automatic stamping of cross-page seal and stamping machine using paper feeding and positioning device

Abstract

The invention relates to a paper feeding and positioning device for the automatic stamping of cross-page seals and a stamping machine using the paper feeding and positioning device. The paper feedingand positioning device comprises paper feeding rollers, a paper pressing groove, limiting teeth, a layered elastic sheet, a sheet pressing rod and an elastic sheet frame; the paper feeding rollers cansequentially convey paper to the paper pressing groove one by one; the paper pressing groove is lower than the paper feeding rollers; a paper limiting block is arranged on one side, close to the paper feeding rollers, of the paper pressing groove, so that the paper can neatly fall into the paper pressing groove; a plurality of elastic feeler gauges are fixed together so as to be integrally manufactured into the layered elastic sheet, and the layered elastic sheet can rotate along with the elastic sheet frame; the limiting teeth are arranged near the layered elastic sheet, so that the feeler gauges deform to a certain extent and rotate to a position above the limiting teeth after the layered elastic sheet rotates forwards by a certain angle; after the layered elastic sheet reversely rotates by a certain angle, one end of each feeler gauge leans against the corresponding limiting teeth, so that the limiting teeth move or the feeler gauges are sequentially released and rotated into the paper pressing groove after being rotated; and the sheet pressing rod can move up and down and can extrude the layered elastic sheet at the lowest position, so that the paper can be pressed by the layered elastic sheet after entering the paper pressing groove.

Description

technical field [0001] The invention relates to a paper-feeding and positioning device for automatically stamping seam-mounted stamps and a stamping machine using the device. Background technique [0002] The existing stamping machine brands mainly include Zhuhai Sigete, Seidman, Japan-US Kaikai, etc., which can realize automatic stamping, fingerprint recognition authorization, remote control, scanning and uploading and other intelligent functions, but it is still very difficult to stamp and seal. Difficult to achieve precise automation. [0003] In the promotion of office automation, stamping machines have been widely used in order to ensure the safety of stamping and reduce the manpower required for stamping. Existing seal machine is made up of parts such as casing, seal arm, seal and operating software, is used for carrying out seal to single sheet. Among them, the stamp is locked in the case, the operator puts the single sheet of paper in the specified position in the ...

AI Technical Summary

Problems solved by technology

On the one hand, there will be a gap for this rotation between each stopper rod and the stopper piece, and the stopper rod and the stopper piece must enter the space where the paper is located from the side of the document to be covered with the seam stamp, which both lead to It is not easy to form a flat slope to cover the seam seal to an ideal degree

In addition, when the total thickness of the document is too small, it is difficult to insert multiple feeler gauges laterally into several pages of documents to keep the document intact; The sides of the file form the ideal saddle stamp slope

[0009] Although the patent No. CN 106864060 B has further improved the above structure, its structure is complex and the speed of putting the feeler gauge into the paper is slow and cannot realize fast automatic operation
