Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for a sanding machine. Background Art

[0002] Sanding machines are mechanical equipment used to complete sanding work. They involve a wide range of industries and categories. However, people in the industry generally call those with automatic feeding systems sanding machines, and others are called belt machines, grinding wheels, and polishing machines. Some dust will be generated during the operation of the sanding machine, which generally needs to be collected by a dust suction device.

[0003] Chinese patent authorization announcement number CN218696837U discloses a wood board sanding machine with a dust collection device, comprising: a cabinet, a vertical frame, a sanding belt and a sanding roller; the cabinet is connected to the vertical frame, and the cabinet serves as a supporting base, and the connecting roller is connected to the sanding belt; a driven sprocket is connected to one end of the connecting roller, a chain is connected to the driven sprocket, and a driving sprocket is connected to the lower part of the chain, and a sanding roller is arranged above the sanding belt; the air carrying debris in the vertical frame is sucked into the transfer box by the exhaust fan, and after being graded and filtered, it is discharged from the exhaust fan outlet, so that the debris can be collected and filtered to prevent the debris from being suspended in the air, thereby protecting the workers, and by rotating the T-shaped handle, the linkage rod can be driven to rotate, and then the two sets of threaded rods are driven to rotate at the same time, so as to raise or lower the sanding roller, so that the gap between the sanding roller and the sanding belt can adapt to wooden boards of different thicknesses, which is more convenient to use;

[0004] The above-mentioned prior art solution has the following shortcomings: the air collecting hood is always located above the sanding roller. When the top of the wooden board is polished, wood chips are diffused around under the action of the sanding roller. Part of them is absorbed by the air collecting hood, and part of them will still diffuse in the working environment, affecting the respiratory health of the workers. In order to further improve the waste chip treatment effect, it is necessary to design a sanding machine dust collection device to solve the above problems. Utility Model Content

[0018] Through the elastic effect of the first spring, the bottom end of the outer protective frame is in contact with the top of the rack or the top of the wooden board when the sand roller contacts the wooden board for polishing. When the wooden board slides to one side for polishing, the friction between the bottom end of the outer protective frame and the top of the wooden board is reduced to prevent sawdust from spreading around and affecting the working environment when the wooden board is polished, and effectively protect the respiratory tract of the staff. When the sand roller is lowered as a whole, it cooperates with the hose to facilitate the centralized collection of polishing dust by the waste treatment box.
