Description

Technical Field

[0001] The utility model relates to the technical field of longitudinal sawing machines, in particular to an automatic single-chip numerically controlled longitudinal sawing machine. Background Art

[0002] The single-blade longitudinal saw is one of the more common processing equipment in the field of wood cutting. Because the longitudinal saw has high precision and stable performance, it is mainly used for longitudinal cutting and trimming of wood. Longitudinal cutting is cutting along the length of the wood to divide the wood into two.

[0003] At present, when dining chair leg processing factories are processing solid wood dining chair legs, the original wooden boards used for processing dining chair legs usually need to be cut and split using mechanical equipment, and the automatic single-piece CNC longitudinal sawing machine is a very common wood cutting mechanical equipment.

[0004] The existing longitudinal sawing machine has the disadvantages of being unable to achieve fully automated cutting, the wood is not firmly fixed, and the cutting adjustment is not perfect. In addition, the debris accumulated on the workbench is small in size and light in weight, and a large amount of debris is difficult to clean up after falling on the ground, which increases the labor intensity of workers. For this reason, we propose an automatic single-chip CNC longitudinal sawing machine. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic single-chip CNC longitudinal sawing machine that can automatically cut the dining chair legs, can clamp and fix the dining chair legs, and can adjust the horizontal and vertical heights.

The dust removal mechanism provided solves the problem that debris is difficult to clean after falling on the ground, reduces the labor intensity of workers, has high practicality, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the automatic single-chip CNC longitudinal sawing machine includes a base, a moving mechanism, a clamping mechanism, a lifting mechanism, a dust removal mechanism and a cutting mechanism;

The dust removal rack can filter the dust or waste chips in the air, thereby preventing people from inhaling dust into their bodies and causing injuries. It solves the problem that the debris is difficult to clean after falling on the ground, and reduces the labor intensity of workers.

[0016] Furthermore, the cutting mechanism includes a cutting blade, a connecting shaft, a driving motor, a fixed bearing and a fixed sleeve. A cutting blade is rotatably arranged between the two U-shaped slides. The left and right sides of the cutting blade are fixedly connected to the connecting shaft through a fixed assembly.
