A wood board processing cooling dust cover

Abstract

This utility model relates to the field of wood processing technology and proposes a wood processing cooling and dust collection hood, including a processing table with a cutting opening at the top center. A cutting machine is screwed to the inner top of the processing table. This wood processing cooling and dust collection hood, by activating the exhaust fan, utilizes a corrugated telescopic tube, a filter cartridge, and a suction pipe to generate suction at the suction frame, thereby removing wood cutting debris. Simultaneously, it absorbs the heat generated during processing. The suctioned air enters the filter cartridge and is filtered by three layers of filter cotton. By rotating the screw block, under the transmission action of the vertical rod, three spur gears can be driven to rotate synchronously. Since the spur gears are engaged with the inner gear, their rotation drives the inner gears to rotate as well. A scraper cleans the surface of the filter cotton while the inner gears rotate, preventing debris from clogging the filter pores and affecting the filtration effect.

A corrugated telescopic tube is fitted onto the top end of the filter cartridge. An air extractor is installed at the top, and the input end of the air extractor is connected to the other end of the corrugated telescopic tube. Three filter cottons are equidistantly arranged inside the filter cylinder. Three internal gears are equidistantly engaged inside the filter cylinder, and the three internal gears are located below the bottom of the three filter cottons. Scrapers are welded to the top and bottom of one side of each internal gear. A vertical rod is inserted into the top of the filter cylinder, and one end of the vertical rod extends to the bottom of the filter cylinder. A screw block is welded to the top end of the vertical rod. Three spur gears are equidistantly welded on the vertical rod, and the three spur gears mesh with the inner sides of the three internal gears.

[0007] Preferably, the outer wall of the scraper is in contact with the filter cotton, the pore size of the three filter cottons decreases sequentially from bottom to top, and the outer contour of the filter cotton fits the inner contour of the filter cylinder.

[0008] Preferably, the top end face of the dust cover is screwed with four damping telescopic rods, and the telescopic ends of the four damping telescopic rods are respectively screwed and fixed to the bottom perimeter of the air extractor. A motor is provided on one side of the cutting machine.

A movable plate is inserted into the movable groove, and a pair of springs are screwed to the top end face of the movable plate. The top end of the springs is screwed to the top of the inner wall of the movable groove, and the bottom of the sealing plate is rounded.

[0010] Preferably, both sides of the dust cover are fitted with threaded rods, both sides of the cut opening are provided with sliding grooves, and a clamping plate is provided above the top of the sliding groove. Several rollers are equidistantly clamped to the outer wall of the clamping plate, and a slider is welded to the bottom of the clamping plate, with one end of the bottom of the slider extending into the sliding groove.

[0011] Preferably, the threaded rod is made of magnet, the clamp is made of ferritic stainless steel, and one end of the threaded rod passes through the suction frame and is magnetically connected to the outer wall of the clamp.

[0015] By activating the air extraction machine, the corrugated telescopic tube, filter cartridge, and suction pipe generate suction at the extraction frame, removing debris from the wood cutting process. Simultaneously, it absorbs the heat generated during processing. The extracted air enters the filter cartridge and is filtered by three layers of filter cotton. Rotating the screw block, driven by the vertical rod, drives three spur gears to rotate synchronously. Because the spur gears are engaged with the internal gear, their rotation drives the internal gears. A scraper cleans the surface of the filter cotton as the internal gears rotate, preventing debris from clogging the filter pores and affecting the filtration effect. This method effectively removes debris generated during wood cutting, preventing it from entering the air and causing air pollution, thus protecting the health of workers.

[0016] Water from the tank is pumped into the spray gun via a pump and pipes and then sprayed from the atomizing nozzles to wet the cutting machine blades, thus cooling them. A fan provides secondary cooling to the blades and dries the moisture. A filter screen filters the air, and a water collection box collects excess water from the atomizing nozzles. A spring pushes the sealing plate out of its slot and into contact with the material being cut, reducing debris splashing. Attached Figure Description
