Embodiment Construction

[0013] The basic structure of the present invention is shown in Fig. 1, 2, and paper feeding machine is made up of main and auxiliary stacking table and main and auxiliary transmission device, and drive wheel 3 is connected on the output shaft of main motor 1, through main transmission chain 5, transmission wheel 7 and The transmission rod 9 drives the main stacking frame 11, the output shaft of the auxiliary motor 2 is connected with the secondary driving wheel 4, and the secondary stacking frame 12 is driven by the transmission chain 6, the transmission wheel 8 and the transmission rod 10. The main paper stacker 11 is a rectangle whose four corners on both sides are respectively hung on the end of the main drive chain 5 for fastening. The two ends on both sides of the auxiliary paper stacker 12 are respectively hung on the ends of the auxiliary transmission chain 6 for fastening. The main stacking frame 11 is arranged on the lower half of the left and right frames 19, 18 to ...

Abstract

A paper feeding device of the offset press without stopping includes a paper feeding electric machine, a driving chain, a driving wheel and a paper folding table suspended on the end of the driving chain and a contact switch circuit, characterized in that the main and subsidiary driving chains and the main and subsidiary driving wheels, and the main and subsidiary paper folding tables suspended on the end of the driving chain are provided, the main paper folding table is composed of a main paper folding frame and a main paper folding plate on placed on the main paper folding frame, the single elevating main paper folding frame is provided in the single elevating subsidiary paper folding frame, the paper moving rob shifts by turns between the main paper folding frame and the subsidiary paper folding frame. The invention can not influence the continuous printing of the offset press, the generated aberration can be obviously improved, using the dynamic structure of paper feeding with elevating by turns of the main and subsidiary paper folding tables and transferring of the paper moving rob on the main and subsidiary paper folding tables, which settles the technological problem of continuous paper feeding without stopping, the invention has outstanding advantage and notable progress for existing offset press.

Description

technical field [0001] The present invention relates to the improvement of offset printing machine, especially the improvement of paper feeding device of offset printing machine. Background technique [0002] Existing printing machines, such as the paper feeding device of an offset printing machine, stack and level a sufficient number of papers on a platform, and rise to a certain height for the paper separator to convey one by one. During the printing process, due to loading After the paper on the paper feeding table is used up, it is necessary to stop the machine to load the paper. After the paper loading is completed, the machine can be turned on again to continue printing. Due to the shutdown and stacking process, the printing will stop, and the printing color difference will affect the quality of the printed matter. Starting from reducing the color difference, It is best to print without stopping to ensure that the color difference is reduced to a minimum. Contents of...
