Description
Technical Field
[0001] The utility model relates to the technical field of an upper paper rack for a rotary printing machine, in particular to an upper paper rack device for a rotary printing machine. Background Art
[0002] A rotary printing press is a type of printing press in which the image to be printed is bent around a cylinder. Printing can be performed on a variety of substrates, including paper, cardboard, and plastic. The substrate can be fed in sheets or unwound through the press on a continuous roll for printing and further modified when necessary (such as die-cutting, varnishing, embossing). Printing presses using continuous rolls are sometimes called "web presses." The rapid development of web printing presses is inseparable from their ability to achieve continuous and fast double-sided printing, in-line cutting and folding, and even high efficiency connected to stacking and bundling, commercial advertising inserts, and distribution equipment. Among the many types of printing machinery and equipment in my country, web printing press products are one of the few varieties that have developed healthily.
[0003] A rotary printing press is a type of printing press in which the image to be printed is bent around a cylinder. Printing can be performed on a variety of substrates, including paper, cardboard, and plastic. The substrate can be fed in sheets or unwound through the press on a continuous roll for printing and further modified if necessary (such as die-cutting, varnishing, embossing). When using a web printing press, a paper feed device is required to continuously feed paper (usually in the form of a roll) to the web printing press. The general paper feed device simply uses a rack, puts the paper roll on the shaft, and then places the shaft on the rack. The structure is simple, although it meets the paper supply requirements. The paper feeding device has no paper buffering and conveying functions, which is inconvenient to use and affects production efficiency. It can only rely on the web printing machine's own traction of the paper to rotate the paper roll. Often, due to the long paper conveying distance and excessive traction force, paper defects such as rupture or cracks appear. It is troublesome to change paper, and it is necessary to stop the machine first, then replace the new paper roll and perform the paper connection (continuation) operation, which is time-consuming and the workers' frequent operations increase the workload. For this reason, we propose a paper rack device for a rotary printing machine. Utility Model Content
