Problems solved by technology

The common problems of the existing sheet-fed offset printing machine paper transfer mechanism are that the stability of the mechanism is poor, and the movement has obvious impact. When the machine is running at high speed, the dynamic performance of the cam linkage mechanism seriously affects the printing quality and reduces the delivery Service life of paper mechanism
The mechanism stability of the above-mentioned conjugate cam paper transfer mechanism is relatively poor, which has an adverse effect on the transfer accuracy of the paper, and at the same time, it is easy to cause the wear of the mechanism

Abstract

The invention discloses a double-output conjugate cam-connecting rod paper-transferring mechanism and belongs to the technical field of a paper-transferring mechanism for a sheet-fed offset press. The paper-transferring mechanism is provided with a connecting rod mechanism on the basis of the traditional conjugate cam-connecting rod paper-transferring mechanism, wherein a pair of conjugate cams is matched with two sets of connecting rod mechanisms. The alternative double output of paper sheet is realized, and the rotation speeds of the paper-transferring mechanism and paper-transferring cam are efficiently reduced, thereby reducing the influence of the dynamic property on the mechanism, obviously increasing the paper-transferring speed even under the condition of maintaining the rotation speed of the cam, and lowering the demand on the property of the paper-transferring cam and reducing the aging speed of the mechanism, so the double-output conjugate cam-connecting rod paper-transferring mechanism has the advantages that the motion output is accurate, high-efficient and stable, the operation is easy, and the mechanism is fit for being applied to the sheet-fed offset press or other printing equipment.

Description

technical field [0001] The invention relates to a conjugate cam paper delivery mechanism, in particular to a double-output conjugate cam-link paper delivery mechanism, which belongs to the technical field of sheet-fed offset press paper delivery mechanisms. Background technique [0002] The sheet-fed offset printing machine needs to continuously and accurately transport the paper from the fixed position to the position of the printing cylinder for printing. The paper transfer mechanism is the key motion output system to realize the paper transfer function. Existing sheet-fed offset presses are varied. Typical sheet-fed offset press paper transfer mechanisms include eccentric rotary swing type, center swing and eccentric paper transfer roller combined type, rotary drum type, and swing type paper transfer mechanism based on rocker slider mechanism. The common problems of the existing sheet-fed offset printing machine paper transfer mechanism are that the stability of the mech...
