[0001] The utility model relates to the field of circuit board production, in particular to a cutting device for circuit board processing. BACKGROUND

[0002] The circuit board is named as ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board and the like. The circuit board makes the circuit miniaturization and intuition, and plays an important role in the batch production of fixed circuit and the optimization of electric appliance layout. The circuit board raw material plate of prior art needs to be manually adjusted in width during cutting, which is inconvenient.

[0003] The cutting device for circuit board with publication number CN219946367U has two end shafts installed on the upper side of the conveying mechanism through bearings. Although the cutting blade can be moved to the required position to facilitate the slitting of different width plates, the cutting blade will inevitably be worn out after long-term use and needs to be replaced. Since the cutting blade is penetrated by the shaft, the shaft needs to be disassembled before the cutting blade is replaced, and the process is relatively complicated. In addition, the installation position of the shaft is relatively high and the shaft is relatively heavy, which further increases the difficulty of installation and disassembly of the shaft, making it difficult to replace the cutting blade.

[0004] Therefore, the utility model provides a cutting device for circuit board processing, which can adjust the positions of the cutting blades along a straight line and replace the cutting blades easily. UTILITY MODEL CONTENTS

When the cutting blade is damaged, the limiting of the cutting blade is released by dismounting the locking nut, and then the cutting blade is dismounted and replaced. The time consumption is reduced, the maintenance time is shortened, and the labor intensity of the workers is reduced. BRIEF DESCRIPTION OF DRAWINGS
