Paper aligning device and working method thereof

Abstract

The invention discloses a paper aligning device, which is characterized by comprising a power source, a cam connecting rod mechanism, a direction changing mechanism, a front paper aligning device, side paper aligning devices and a breadth adjusting device, wherein the power source is connected with the power input end of the cam connecting rod mechanism; the power output end of the cam connecting rod mechanism is connected with the direction changing mechanism and the front paper aligning device; the side paper aligning devices are connected with the direction changing mechanism; front paper aligning and side paper aligning actions of the front paper aligning device and the side paper aligning devices are realized through the direction changing mechanism by using the same power source; the breadth adjusting device is connected with the side paper aligning devices. In a working method of the paper aligning device, the distance between the two side paper aligning devices is adjusted through the breadth adjusting device; the power source is used for driving the cam connecting rod mechanism to act, and the direction changing mechanism connected with the cam connecting rod mechanism moves together, so that the front paper aligning device and the side paper aligning devices act simultaneously. The paper aligning device has the advantages that paper aligning actions in front / back direction and left / right direction can be finished by using one power source, and the structure is flexible.

Description

(1) Technical field: [0001] The invention is suitable for printing machines, especially a paper-aligning device and its working method. (2) Background technology: [0002] The paper-jacking device in the prior art has two forms: [0003] One form is: use the cam link as the power to drive a cardboard to move the paper neatly. In order to adapt to different paper, the cardboard needs to be able to adjust the format. In the existing method, the cardboard is installed on a slidable shaft, and the shaft is slidably matched with the fixed block fixed on the wallboard. When the width needs to be adjusted, the shaft slides relative to the fixed block to drive the cardboard to move to complete the width adjustment. One problem with this construction is that the shaft sticks out of the machine. Depending on the format, the protruding length will be different, and the position of the paperboard and the paper stack cannot be seen during adjustment, which is inconvenient to adjust, a...

AI Technical Summary

Problems solved by technology

The adjustment is very convenient, but there is a problem, the power of Qi cardboard is the cylinder

When the cylinder performs paper alignment at high speed, the action is not slow and the impact is large, resulting in uneven paper alignment and poor paper alignment

But if the cylinder is adjusted to ease, the movement frequency of the cardboard will not keep up with the speed of the machine, and cannot meet the needs of high-speed equipment
