Description

Technical Field

[0001] The utility model relates to the technical field of cardboard cutting, in particular to a cardboard cutting machine. Background Technique

[0002] A cardboard cutting machine is a device used to cut cardboard, and is used to cut cardboard to the required size during the production process of cardboard.

[0003] The Chinese patent discloses a cardboard cutting machine with the publication number of CN208529210U, which includes a sliding plate slidably connected to the two side chassis walls at the feeding port of the cutting machine along the vertical direction; a motor installed on the sliding plate; a rotating shaft fixed on the output shaft of the motor and extending perpendicular to the cardboard conveying direction; a roller sleeved on the rotating shaft and in contact with the cardboard; and a limiting component installed on the chassis for limiting the sliding plate. When the cardboard cutting machine of the utility model is in use, it can automatically take out the cut cardboard instead of manual operation, making the operation process more convenient and safer.

[0004] However, it still has the following disadvantages: The device pushes a stack of papers into the device for cutting and cuts off the four sides. However, during the process of pushing a stack of papers in, the papers at the bottom layer may be misaligned with the papers at the upper layer, resulting in the edges of the papers not being aligned anymore, which affects the cutting of the papers. For this reason, we propose a cardboard cutting machine to solve this problem. Content of the Utility Model
