BAIDU_CLB_fillSlot("858283"); What part of the paper feed system for a sheetfed press is made up of? The paper-feeding system of a sheet-fed printing press refers to a system for continuously and accurately feeding a single sheet of paper to a printing device on an offset printing press. The paper-feeding system mainly includes two parts: a paper separating and conveying device and a registering device. What are the requirements for sheet feeders for sheet feeders? The specific requirements of the sheet-fed offset press for the paper-feeding device are as follows: (1) It shall be ensured that papers of different specifications, different thicknesses, and different amounts of weight are reliably separated from the heap of paper stacks in a reliable, accurate, and periodic manner, and Delivery to the regulation mechanism. (2) It does not damage the paper surface during the paper conveying process, does not pick up dirty printed images, and does not damage the paper edge. (3) The paper stack can be replenished or replaced during the transportation of the machine to ensure long-term continuous printing. (4) The detection interlock device should be sensitive and reliable to ensure that the paper transport can be stopped in time when paper feeding or printing failures occur. Which mechanism constitutes the automatic paper feeder? What is the role of agencies? The mechanisms and functions of the automatic paper feeder are as follows: (1) The paper separation mechanism. Accurately separate the paper stacks one by one and send them to the paperboard. (2) Paper lifting mechanism. The paper piles that are to be printed together are automatically raised gradually to the corresponding height as the paper gradually outputs. (3) Paper feeding mechanism. The paper separated by the paper separation mechanism is precisely transported to the gauge part through the paper feeder for positioning. (4) Air system, with the paper separation mechanism to distribute the air blow or suction to the mouthpiece or suction nozzle, which includes the air pump, air circuit and air valve. (5) Automatic control system. Including double sheet, empty sheet, ram sheet, and broken paper automatic control device, it can automatically terminate the operation of the sheet feeding unit when a variety of sheet feeding failures occur, and can generate a series of mechanical actions required for printing. , Slow down the speed of the machine. When the sundries in the paper touch the safety bar during transportation, the machine will automatically stop running. What are the basic properties of automatic feeders? Automatic feeders should have the following basic properties: (1) Higher feed and feed speeds to accommodate host needs. (2) The paper can be reliably, smoothly and accurately transported to the register device for correct positioning. (3) When the variety and specification of the paper change, it can be easily adjusted. (4) To ensure the correct separation of the paper, a device for preventing double sheets should be provided. (5) During the printing process, the stacker table can be automatically raised to maintain a reasonable height of the stack, and the stacker can be replenished as much as possible without stopping the machine. (6) The paper cannot be damaged during the feeding process, and the printed surface cannot be dirty. (7) When there is a failure such as double sheet, ram sheet or residual paper, a reliable automatic stop device is required. (8) The mechanism is simple, easy to operate, and has a small footprint. The necessary adjustments can be made during the operation of the machine.
