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.

Example Embodiment

[0011] A preferred embodiment of the present invention is described as follows with reference to the drawings:
[0012] See figure 1 , Dual-output conjugate cam-link paper delivery mechanism, including a conjugate cam composed of a main cam 1 and a secondary cam 2 installed on the transmission shaft 5, an arcuate swing arm 6, a transmission swing arm 8, a connecting rod 9 and a paper delivery The swing arm 10 and the arcuate swing arm 6 are provided with two pressure rollers 3a, 3b at both ends. The two pressure rollers 3a, 3b respectively contact the outer circumferential surfaces of the main cam 1 and the auxiliary cam 2, and drive the swing arm 8. One end of the transmission arm is fixedly connected with the middle part of the arcuate swing arm 6. The transmission swing arm 8 and the arcuate swing arm 6 are rotatably supported by a fulcrum shaft 7 and jointly swing around the fulcrum shaft 7, and the other end of the transmission swing arm 8 is hinged with the connecting rod 9. The connecting rod 9 has one end hinged with the paper delivery swing arm 10. The paper delivery swing arm 10 is supported by a pivot axis 16 to swing around the pivot axis 16, and consists of a transmission swing arm 8, a connecting rod 9, and a paper delivery swing arm 10. A set of plane four-bar linkage mechanism forms the first end output system of the paper transfer action. The dual-output conjugate cam-link paper delivery mechanism also includes a second set of flat four-link mechanisms to form a second end output system for the paper delivery action. The second end output system and the first end output system alternately output the paper delivery action. The two-group plane four-bar linkage mechanism is composed of a second transmission swing arm 13, a second link 14, and a second paper transfer swing arm 15. One end of the second transmission swing arm 13 is fixed to the middle part of a second arcuate swing arm 11. Connected, the two ends of the second arcuate swing arm 11 are provided with two second pressure rollers 4a, 4b, the two second pressure rollers 4a, 4b are also in contact with the outer circumferential surfaces of the main cam 1 and the auxiliary cam 2, respectively , And set at a corresponding position away from the pressure rollers 3a, 3b, the second transmission swing arm 13 and the second arcuate swing arm 11 are rotatably supported by a fulcrum shaft 12 to swing together around the fulcrum shaft 12, the second transmission pendulum The other end of the arm 13 is hinged with the second link 14, and the second link 14 has one end hinged with the second paper delivery swing arm 15. The second paper delivery swing arm 15 is rotatably supported by a fulcrum shaft 17 and surrounds the fulcrum shaft. 17 swing. The paper delivery swing arm swings back and forth around the fulcrum axis, and sequentially sends the paper to the printing cylinder for printing. Each swing can pass a piece of paper.
[0013] See figure 1 , The conjugate cam of the dual output conjugate cam-link paper transfer mechanism of the present invention rotates in the same direction as the paper transfer roller, and the speed of the conjugate cam is preferably half of the speed of the paper transfer roller. When the speed of the paper transfer roller of the sheet-fed offset printing machine is high, the dual output conjugate cam-link paper transfer mechanism of the present invention can effectively reduce the speed of the paper transfer cam of the paper transfer mechanism to reduce the dynamics of the mechanism when the mechanism is subjected to high speed. The impact of performance, even when the cam speed is unchanged, the paper transfer speed can be increased significantly, and the performance requirements of the paper transfer cam are also reduced and the mechanism aging speed is slowed down.
[0014] See figure 1 , Dual-output conjugate cam-link paper delivery mechanism, two sets of plane four-link mechanism, the fulcrum axis 16 of the paper delivery swing arm 10 and the fulcrum axis 17 of the second paper delivery swing arm 15 are coaxial, two paper delivery pendulums The arms respectively oscillate around the pivot axis to alternately send the paper to the printing cylinder for printing.
[0015] In order to ensure that the output ends of the dual output cam-link paper delivery mechanism meet the requirements of the law of motion, the size and installation position of the dual link mechanism must be checked. Therefore, the dual-output conjugate cam-link mechanism has the characteristics of accurate motion output, high efficiency, stability, and easy operation.
[0016] The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, and various changes can be made according to the purpose of the present invention. Any modifications, equivalent replacements, improvements, etc. made should be included in the protection scope of the present invention.
