Technical Field

[0001] The utility model relates to the technical field of supporting mechanisms for precision cutting machines, specifically to the manipulator feeding mechanism of a precision cutting machine. Background Technique

[0002] The precision cutting machine is a branch of the cutting machine, mainly used for the fine cutting of wood sheets, and is mostly used in the processing of components such as wooden doors and cabinet doors, with wide applications in the furniture processing field.

[0003] Currently, the common precision cutting machines on the market mostly use manual feeding or cylinder feeding for cutting. Manual feeding has relatively high risks during cutting, while the overall structure of cylinder pushing is relatively simple. It advances by pressing against the side of the sheet material with a cylinder. In actual use, there are some functional deficiencies and room for improvement. For example, with direct cylinder pushing, it can only move in one direction and cannot pull the sheet material back. When cutting irregular shapes or when refeeding is required, there are operational shortcomings, and manual refeeding is needed, which is rather troublesome. Moreover, during the cutting process, the sheet material is prone to displacement and vibration driven by the saw blade or saw wire, resulting in a decrease in cutting accuracy, and it does not have the function of stable feeding with manipulator clamping.

[0004] Now, a new manipulator feeding mechanism for a precision cutting machine is proposed to solve the above problems. Content of the Utility Model
