Description

Transfer mechanism of paper feeder

technical field

The utility model belongs to the technical field of machinery and relates to a paper feeder, in particular to a transfer mechanism of the paper feeder.

Background technique

The paper feeding mechanism of the sheet-fed printing machine is a very important auxiliary machinery in the offset printing machine. Its main component - the separation head, through a series of suction nozzles and blowing nozzles, sucks up the paper from the paper pile, separates, Pass it on to the printing department. The paper feeder is also widely used in sheet-fed printing machinery and equipment such as screen printing machines, gravure printing machines, automatic die-cutting machines, and laminating machines.

According to different requirements, the paper feeder can be divided into the following two types according to the requirements of precision and speed: 1. Intermittent paper feeder: After the separation head sends a piece of paper into the printing department, it then sends the second piece of paper, and it goes back and forth in sequence. For low speed printing machinery. 2. Stream-type paper feeder: the separation head continuously feeds paper, and the paper is lapped on the paper feeder to realize fast paper feeding. It is mainly used for high-speed printing machinery, and currently it is mainly used for sheet-fed multi-color printing machines.

The working principle of the movement in the printing process is: 1. The paper separating nozzle moves downward, after sucking the top sheet of paper, it lifts up and tilts back to prevent double sheets from being sucked up, and facilitates the insertion of the pressure nozzle . 2. Insert the paper pressing nozzle, press the paper below and open the blowing air path to blow the air, so that the sucked paper is separated from the paper below, and the height of the paper pile is detected at the same time. 3. The paper delivery nozzle sucks the paper and moves to the right. At this time, the paper separation nozzle and the paper delivery nozzle control the paper at the same time, and the paper is handed over, that is, the paper separation nozzle is handed over to the paper delivery nozzle. 4. The paper separation nozzle cuts off the air path to release the paper, completes the paper transfer, and then rises up. At this time, the paper pressure nozzle stops blowing air and leaves the paper pile, and the paper delivery nozzle moves to the left to output the paper. 5. With the continuous output of paper, the paper pile monitoring system of the paper feeder will raise the height of the paper pile at any time to ensure uninterrupted paper feeding.

At present, the paper feeding transmission mechanism of the paper feeder has a conveyor belt and a bottom plate, and the conveyor belt and the bottom plate are all made of rubber materials. Although the price of this material is relatively low, these materials are not conductive. For example, when the paper is transferred at high speed, the paper will generate static electricity, and it will be easily adsorbed on the conveyor belt or the bottom plate, causing the paper to become wrinkled.
