The invention discloses a device for feeding a plate to the outer circumferential face of a printing plate cylinder. The device comprises a rack, and a guide rail is arranged on the inner bottom of the rack. Positioning plates are arranged at the positions, facing inwards, of the front face and the back face of the rack. A stop mechanism and a drilling mechanism are arranged on the inner top of the rack. The stop mechanism comprises a first guide base and first hydraulic cylinders; a plurality of first guide grooves are formed in the side portion of the first guide base; a first piston rod is arranged on the lower portion of each first hydraulic cylinder and penetrates through the corresponding first guide groove; and a stop plate is arranged among the lower ends of the first piston rods. The drilling mechanism comprises a second guide base, second hydraulic cylinders and third hydraulic cylinders; a plurality of second guide grooves are formed in the second guide base; and a second piston rod is arranged on the lower portion of each second hydraulic cylinder and penetrates through the corresponding second guide groove. By means of the device for feeding the plate to the outer circumferential face of the printing plate cylinder, the printing plate can be wound on the outer circumferential face of the printing plate cylinder, locking connection is firmer, and operation is more convenient.
Description
technical field [0001] The invention relates to a plate loading device, in particular to a printing plate cylinder peripheral surface printing device. Background technique [0002] The plate cylinder rotates on the side of the impression cylinder, and is consistent with the line speed of the impression cylinder. During a short stop, the ink fountain roller and anilox roller move up and leave the plate cylinder, while the ink fountain roller and anilox roller continue to rotate to facilitate ink distribution and keep the ink on the anilox roller from drying. The ink fountain roller rotates on one side of the anilox roller, and its tangential speed is lower than that of the anilox roller, in order to control the amount of ink and prevent printing ink from splashing. Most of the printing machines used for printing corrugated paper are combined flexographic printing machines. Each unit of this flexographic printing machine is independent and arranged in a horizontal line. R...
