Description

Technical Field

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

[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and a layer of boxboard. It has good elasticity and extensibility and is mainly used to make cartons, carton sandwiches and other packaging materials for fragile goods. Corrugated cardboard is mainly made of traditional straw pulp and waste paper through pulping to make raw cardboard similar to yellow cardboard, which is then mechanically processed and rolled into a corrugated shape.

[0003] The existing corrugated paper cutting device is driven by a motor to smoothly feed the corrugated cardboard into the cutting area. Before the cardboard enters the cutting area, it needs to be accurately positioned by a positioning device. During the cutting process, the cutting blade moves relative to the drive motor to cut the cardboard.

[0004] When existing corrugated paper cutting devices cut corrugated cardboard, the corrugated paper clamping and fixing mechanisms are mostly unable to adjust the spacing and cannot clamp and fix corrugated paper of different lengths, resulting in poor applicability. In addition, when the current corrugated paper cutting devices are working, the impact force caused by the downward movement of the cutting blade will damage the cutting workbench of the corrugated paper cutting device, which will greatly reduce the service life of the cutting workbench of the corrugated paper cutting device over time. Utility Model Content
