Paper rolling mechanism for printing machine

Abstract

The invention discloses a paper rolling mechanism for a printing machine. The paper rolling mechanism comprises two parts including a paper feeding part and a paper receiving part; the paper feeding part and the paper receiving part are fixed to the two ends of a working table of the printing machine, and roll paper is conveyed through the paper feeding part, is pulled by the working table of the printing machine to the paper receiving part, and is tightly pasted to the working table of the printing machine; the paper feeding part and the paper receiving part are fixed to a single arm support plate on the working table of the printing machine in a single cantilever manner and are independently driven by driving devices to rotate; and expanding devices are arranged inside paper cores on the paper feeding part and the paper receiving part. According to the paper rolling mechanism for the printing machine, single cantilever structures are adopted, the structure is simple, and operation is convenient; and the expanding devices are arranged on the paper rolling mechanism, the roll paper can be fixed from the interior of the paper cores, the problem that the paper cores are not tightly clamped is effectively solved, the problem that resistance exists during rotation of the paper receiving part is solved, and the using effect of the paper rolling mechanism for the printing machine is improved.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a roll paper mechanism for a printing machine. Background technique [0002] In the printing operation, the rolling paper mechanism has the function of protecting the printing table and preventing the ceramic plate on it from being blocked by the slurry. [0003] The traditional paper roll mechanism consists of two parts, the paper feeding part and the paper receiving part. It adopts the double cantilever clamping method. The left and right clamping mechanisms clamp the paper core and lock it on the rotating shaft, so that the paper core moves synchronously with the rotating shaft; The paper is drawn out from the paper core on the paper feeding part, crosses the printing table, and is fixed on the paper core on the paper receiving part. Make the roll paper tight. [0004] The traditional roll paper mechanism for printing presses has the following disadvantages: [0...

Problems solved by technology

[0008] The purpose of the present invention is to solve the above technical problems and provide a roll paper mechanism for printing machines, which adopts a relatively simple single cantilever structure and is easy to operate; it is equipped with a tensioning mechanism, which can be fixed from the inside of the paper core, effectively It avoids the problem that the paper core is not tightly loaded, solves the problem of resistance in the rotation of the roll paper, and improves the use effect of the roll paper mechanism for the printing machine
