Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing equipment, in particular to an opening and closing mechanism of a cardboard slitting and creasing machine. Background Art

[0002] Cardboard longitudinal slitting creasing means that when the cardboard is cut longitudinally, it is usually creasing first. This process can form a groove on the surface of the cardboard by applying a certain amount of pressure on the cardboard, but not completely cutting the cardboard, so that it can be cut more easily and accurately later. This creasing can help ensure that the cardboard will not break or be damaged during the cutting process, and it also helps to improve the accuracy and efficiency of cutting.

[0003] When the opening and closing mechanism of the existing cardboard longitudinal cutting and creasing machine is in use, when the creasing tool is used to creasing the cardboard, when the creasing tool contacts the cardboard, the two ends of the cardboard at the creasing position will be lifted up, which will affect the accuracy of the creasing during use and further affect the subsequent cutting.

[0004] For this purpose, an opening and closing mechanism of a cardboard slitting and creasing machine is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and provide an opening and closing mechanism of a cardboard longitudinal cutting and creasing machine.

The guide assembly 5 guides and limits the mounting frame assembly 3 and the creasing tool 4 when they move vertically. Before the creasing tool 4 moves vertically downward and contacts the surface of the cardboard, the bottom surface of its clamping mechanism 6 is arranged in contact with the surface of the cardboard. The clamping mechanisms 6 located on the front and rear sides of the mounting frame assembly 3 clamp the two sides of the cardboard to be indented, thereby preventing the cardboard from being displaced or tilted when the creasing tool 4 indents it.
