Background

The paper collecting function of the gravure press splitting machine for splitting large sheets is completed by two sections of paper conveying belts of the splitting machine with different speeds. The first belt section of the splitting machine with the splitting cutter is a high-speed belt, and the linear speed (which can be finely adjusted within a certain range) of the splitting machine is slightly higher than the paper feeding speed (namely the paper feeding speed of the gravure press during normal printing) so as to ensure a certain gap between two large split sheets before and after splitting and facilitate the collection of the second belt section. The second section of belt is a low-speed belt, a certain height difference exists between the second section of belt and the first section of belt in the horizontal direction, and the linear speed (which can be finely adjusted within a certain range) of the second section of belt runs at a linear speed far lower than that of the first section of belt after parameters are set through a computer, so that cut large sheets after cutting can be collected in a laminated mode. However, when the paper collecting mode works stably, the tail end of the front cut large paper must fall in time under the action of the speed reducing wheel on the second section of belt, and the front end of the subsequent cut large paper has instant height drop at the joint of the two sections of belts, otherwise, the front and rear cut large paper will have a paper squeezing phenomenon similar to 'rear-end collision', so that the paper is stacked at the joint of the two sections of belts to cause a serious result of paper jam, and the paper collecting effect is directly influenced.
