Description

Technical Field

[0001] The utility model relates to a corrugated paperboard longitudinal cutting machine, in particular to a tracking and marking longitudinal cutting machine. Background Art

[0002] When longitudinally cutting a corrugated paperboard with pre-printed paper as the face paper, it is necessary to perform longitudinal cutting according to the marks on the face paper. Currently, on a longitudinal cutting machine, a marking identifier (vision sensor) is fixedly provided, and a longitudinally cutting knife that moves horizontally is provided. The longitudinal cutting machine body is horizontally movable and its horizontal movement is controlled by a horizontal driving mechanism. The longitudinally cutting knife moves to the position corresponding to the mark according to the longitudinal cutting requirements of the paperboard and performs longitudinal cutting along with the conveyance of the paperboard; moreover, during the conveyance of the paperboard, the marking identifier continuously detects and transmits data to the control system of the horizontal driving mechanism. When the mark exceeds the set range, the horizontal driving mechanism controls the horizontal movement of the longitudinal cutting machine body, so that the marking identifier returns to the detection range again. At the same time, the positional relationship between the longitudinally cutting knife and the mark on the face paper returns to the normal state, and continues to cut according to the mark.

[0003] However, the longitudinal cutting machine body with the above structure needs to move continuously. Due to its heavy mass, its movement reaction is slow, energy consumption is high, and the cutting accuracy is poor. Summary of the Utility Model

[0008] As a more specific solution, there are two or more longitudinal cutting wheels, and the number of the marking line identifiers is the same as that of the longitudinal cutting wheels and they are combined one by one, and each marking line identifier is arranged along the width direction of the cardboard channel.
