Description

Automatic plate winding device Technical Field The invention relates to the technical field of printing, in particular to an automatic plate reeling device. Background In the printing process of the cartons, different types of cartons need to correspond to different printing contents, and therefore, the offset plate on the printing roller in the printing device needs to be frequently disassembled and replaced. In the installation process, when the offset plate is not firm, the phenomenon that the offset plate moves up and down easily occurs on a printing roller, and when the offset plate is too tight, the offset plate can deform due to stretching, so that the printing quality is not good no matter whether the offset plate is too loose or too tight, and the printing efficiency and the printing quality are often affected by the operation of the offset plate. The plate hanging operation is usually performed by directly fixing the front plate hanging strip of the offset plate on the mounting plate of the printing roller, inserting the rear plate hanging strip into the plate hanging groove of the printing roller, and winding the rear plate hanging strip inserted into the plate hanging groove on the winding shaft to enable the offset plate to be clung to the printing roller. In a traditional printing device, an operator usually uses a wrench to twist a rolling shaft so as to roll an offset plate, and the tightness of plate hanging is completely determined by the operator depending on working experience, so that human factors have great influence. Therefore, in practical production application, the mode often cannot meet the printing quality requirement due to low working efficiency and excessive influence of manual proficiency. In order to solve the above problems, some manufacturers make a device without manual plate hanging, and the device can refer to an automatic plate winding device and a method for a corrugated carton printer, as disclosed in application number 201811241439.8, wherein a gear rack is arranged on a roller shaft of a printing roller, a first plate winding gear and a second plate winding gear are arranged on the gear rack in parallel, a telescopic rack is meshed with or separated from the first plate winding gear under the driving of a cylinder, the second plate winding gear is connected with a plate hanging shaft gear through the plate hanging gear, the plate hanging shaft gear is arranged at one end of a plate hanging shaft, and the plate hanging shaft is arranged on the inner side of the printing roller in parallel. The method is that the telescopic rack is driven by the cylinder to be meshed with or separated from the first plate rolling gear, when the telescopic rack is meshed with the first plate rolling gear, the hanging plate gear rotates around the second plate rolling gear to drive the hanging plate shaft gear to rotate, so that the hanging plate shaft drives the offset plate to be screwed, and when the telescopic rack is separated from the first plate rolling gear, the printing roller can perform printing work. The automatic plate rolling device adopts an air cylinder to drive a telescopic rack to be meshed with or separated from a first plate rolling gear, the first plate rolling gear is clamped through the telescopic rack, motion is generated when a machine moves, the plate rolling is required to be controlled to be clamped to a required position, and the telescopic rack at a preset position is not necessarily aligned with the teeth of the first plate rolling gear, so that the situation that slipping or clamping is easy to occur if the telescopic rack directly stretches out is unsafe, and the telescopic rack is continuously meshed with the first plate rolling gear by controlling the pushing time of the air cylinder, so that the plate rolling stroke is controlled, the control time is long, and electricity is wasted. In addition, it needs to set up first reel version gear, second reel version gear at the axial, accomplishes the link plate action through the cooperation of both, and this kind of structure occupies axial space great, is unfavorable for the miniaturized development trend of equipment. Therefore, the above-described problems are to be solved. Disclosure of Invention In view of the shortcomings of the prior art, the invention aims to provide an automatic plate rolling device, which can solve the problem that the automatic plate rolling device in the prior art slips or is blocked when hanging plates, occupies small axial space and is beneficial to the miniaturization development of equipment. The automatic plate winding device comprises a roller and a driving mechanism for driving the roller to rotate, wherein a plate hanging groove is formed in the outer side surface of the roller, and the automatic plate winding device further comprises: the plate hanging mechanism comprises a rolling shaft positioned in the plate hanging groove, a gear set in transmission connection wit
