Description

Technical Field

[0001] The utility model relates to the technical field of woodworking cutters, in particular to an air-cooled spiral woodworking cutter. Background Art

[0002] Planing of wood and wood-based artificial boards is an important processing method. Woodworking tools are tools that use cutting methods to process wood into required shapes and sizes. Woodworking tools are of two types: hand-used and machine-used. Machine-used woodworking tools are used in batch and mass production.

[0003] The tool peels the wood by rotating during processing, which generates a lot of heat. After a long period of processing, the tool will overheat and easily cause damage to the tool. Therefore, ventilation holes are opened on the surface of the tool to cool it by blowing air. However, when the tool cuts shallowly, the airflow from the ventilation holes that does not enter the cutting area will scatter the wood chips everywhere. Therefore, an air-cooled spiral woodworking tool is proposed, which only blows air on the part that contacts the wood for cutting. Utility Model Content

[0004] In view of the problem that the airflow blown out of the ventilation holes that do not enter the cutting area will scatter the wood chips everywhere, the utility model is proposed.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: an air-cooled spiral woodworking tool comprises a knife column, the outer ring surface of the knife column is provided with a spiral knife groove, the right side surface of the knife column is fixedly inserted with a concentric shaft, the outer ring surface of the knife column is provided with a plurality of connecting ring grooves, the inner wall of the knife column and between each two connected spiral knife grooves are provided with a spiral groove, the inner wall of each spiral groove and between each two connected connecting ring grooves are provided with an air outlet, the interior of each air outlet is slidably inserted with a plug, one end of the plug located inside the spiral groove is fixedly connected with a pushing telescopic rod, the other end of the pushing telescopic rod is fixedly connected to the inner wall of the spiral groove, one end of the plug located outside the knife column is rotatably inlaid with a ball, the outer surface of the concentric shaft is rotatably sleeved with a ring cover, the back of the ring cover is fixedly inserted with an air pump, and the outer surface of the concentric shaft and the interior of the ring cover are provided with a ventilation groove.

[0006] Preferably, the left end of the knife column is conical, the outer surface of the knife column is slidably sleeved with a ring disk, the outer surface of the ring disk is rotatably sleeved with a single-sided breathable suction hood, the left side of the single-sided breathable suction hood is a breathable structure, and the interior of the ring disk is connected to the interior of the single-sided breathable suction hood.

[0007] Preferably, a hose is fixedly plugged into the right side of the ring disk, and the other end of the hose is fixedly sleeved on the rear end of the air pump.

[0008] Preferably, the right side of the single-sided breathable suction cover is fixedly connected to a bar, the front end of the ring cover is slidably sleeved on the outer surface of the bar, the outer surface of the bar is slidably sleeved with a spring, and the two ends of the spring are respectively fixedly connected to the single-sided breathable suction cover and the ring cover.

[0011] Beneficial effects of the utility model:

[0012] 1. By setting a plug, pushing the telescopic rod and the ball, the telescopic rod pushes the plug to block the air outlet. When the knife column rotates to cut the wood, the plug blocks the air outlet that is not in contact with the wood. After the knife column contacts the wood, the cutting surface of the wood pushes the ball to compress the plug and push the telescopic rod, so that a gap is formed between the plug and the air outlet, so that the air flow can pass through the gap between the plug and the air outlet for cooling;

[0013] 2. By setting the ring disk, the single-sided breathable suction hood and the spring, when the knife column rotates and cuts, the spring pushes the single-sided breathable suction hood to contact with the surface of the wood, closing the cutting part, and the air pump uses the hose to make the single-sided breathable suction hood absorb the generated wood chips, effectively preventing the generated wood chips from flying around.
