Edge cutting device for carton processing

Abstract

The utility model provides an edge cutting device for carton processing, and relates to the field of carton edge cutting devices. Two [-shaped supporting plates are fixedly installed on the upper portion of the rack in a left-right symmetry mode, and a [-shaped supporting frame is fixedly connected to the rear sides of the tops of the two [-shaped supporting plates. And a displacement mechanism is mounted at the upper end of the inner side of the [-shaped supporting frame. According to the edge cutting device, by arranging the driving assembly, when the restraining rollers on the two sides move downwards, the restraining rollers on the two sides can move downwards without rotating the two rotating nuts correspondingly, and therefore the convenience of the edge cutting device in the process of adjusting the heights of the restraining rollers is improved; the edge cutting device solves the problem that although an existing edge cutting device can drive a restraining frame to move downwards by screwing twisting discs and restrain the two sides of a carton through the action of restraining rollers and moving rollers, in the adjusting process, the restraining rollers on the two sides can move downwards only by rotating the two twisting discs respectively, and therefore the convenience of adjusting the height of the restraining rollers is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of carton trimming devices, in particular to a carton trimming device. Background Art

[0002] Carton trimming is an important step in the carton processing process. Its main purpose is to ensure that the edges of the carton are flat and smooth, meeting the requirements of packaging and transportation. Trimming usually requires the use of professional cutting equipment or tools, such as panel saws.

[0003] For example, the existing patent application number is: CN202221743679.X, which discloses a positioning and trimming device in carton production. When the trimming device is in use, although the constraint frame can be driven downward by turning the screw disk, the two sides of the carton can be movably clamped by the constraint roller and the movable roller to realize the constraint of the carton board, but during the adjustment process, it is necessary to turn the two screw disks separately to move the constraint rollers on both sides downward, thereby reducing the convenience of the trimming device in adjusting the height of the constraint roller. In addition, after the height of the cutting motor is adjusted, the above-mentioned trimming device fixes the cutting motor by tightening the tightening screw, and the tightening screw is prone to loosening due to force, thereby reducing the stability of the cutting motor during operation. Utility Model Content

Then, the two driving screws move the two lifting plates and the restraining rollers on both sides downward at the same time under the action of the threads. During the adjustment process, since there is no need to rotate the two rotating nuts separately, the restraining rollers on both sides can also be moved downward, thereby improving the convenience of the trimming device in adjusting the height of the restraining rollers.

Then, the two driving screws 502, under the action of the threads, move the two lifting plates 105 and the constraint rollers 106 on both sides downward at the same time. Therefore, during the adjustment process, there is no need to rotate the two rotating nuts 501 separately, and the constraint rollers 106 on both sides can also be moved downward.

[0037] Then the cutting motor 4 is started, and the cutting blade 401 is rotated, and the carton board is placed between the moving rollers 103 on both sides and the restraining rollers 106 on both sides, and then the carton board is pushed backward, and the carton board is cut by the rotating cutting blade 401, thereby completing the trimming process of the carton board.
