Description

Technical Field

[0001] The utility model relates to the technical field of surface grinders, in particular to a surface grinder with a dustproof structure. Background Art

[0002] A surface grinder is a type of grinding machine. It primarily uses a grinding wheel to rotate and grind workpieces to achieve the required flatness. Surface grinders are categorized by worktable shape: rectangular and circular. The main parameters for rectangular surface grinders are width and length, while those for circular surfaces are primarily based on their diameter. Surface grinders generate dust during operation. If not promptly addressed, this can pollute the workshop environment and pose a health risk to operators.

[0003] After searching, in the prior art, Chinese patent publication number: CN220372835U discloses a surface grinder with a dust-proof structure. The utility model includes a surface grinder body, a dust-proof mechanism and a cleaning mechanism. When the surface grinder body processes the workpiece and generates dust, the dust suction hose installed on the input end of the dust removal fan will suck the dust through the dust suction hood installed above the surface grinder body through the support rod, and transport it to the dust removal box through the air supply pipe on the output end. When the dust enters the dust removal box and is discharged through the air outlet on the top surface, the coarse filter, fine filter and activated carbon filter will adsorb and filter the large, small and tiny dust particles carried in the gas. At the same time, the input end of the water pump will pump out the water in the water tank through the liquid outlet pipe and transport the water to the spray pipe through the water supply pipe on the output end, and spray it on the coarse filter, fine filter and activated carbon filter after atomization through the atomizing nozzle to clean the dust adsorbed on them.

[0004] However, the device also has the following defects:

[0005] The device consumes a large amount of water during use, which increases the cost of use and causes waste of water resources. In addition, the device finally mixes the filtered dust with the water and discharges it together. The filtering treatment of sewage further increases the cost of use. The device does not solve this problem well. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] A surface grinder with a dust-proof structure includes a surface grinder body 1; it also includes a dust suction component, the dust suction component includes a dust hood 2, the dust hood 2 is fixedly connected to the surface grinder body 1, one side of the dust hood 2 is fixedly connected to the top of the dust suction hose 3, the bottom of the dust suction hose 3 is fixedly installed on the movable frame 4, the top and bottom of the movable frame 4 are respectively sealed and slidably matched with the top and bottom of the filter box 5, the top and bottom of the movable frame 4 are provided with through holes, and the bottom of the movable frame 4 is fixedly connected to the air inlet end of the exhaust fan 7 through the exhaust hose 6.

[0025] By arranging the exhaust fan 7, the dust suction hose 3 and the dust collecting bag 10, etc., the dust can be collected to prevent the dust generated when the surface grinder body 1 is working from polluting the workshop environment and also to avoid the dust from causing harm to the health of the operator. The dust is concentrated and stored in the dust collecting bag 10, which is convenient for the operator to handle, and the dust collecting bag 10 is reusable, which reduces the cost of use.

[0026] It also includes a filter assembly, which includes a filter box 5. The filter box 5 is provided with two groups of mounting cavities 9. The mounting cavity 9 is provided with openings at the top and bottom of the filter box 5. A dust collecting bag 10 is provided inside the mounting cavity 9. A mounting ring 16 is provided on the top of the dust collecting bag 10. A card slot 17 is provided on the top of the mounting cavity 9. The mounting ring 16 is sealed and connected to the card slot 17. A support frame 8 is fixedly installed on the outside of the filter box 5. The exhaust fan 7 is fixedly installed on the other side of the support frame 8. A support leg 18 is fixedly installed on the bottom of the support frame 8.

[0027] By opening two sets of mounting cavities 9 on the filter box 5, two sets of dust collecting bags 10 can be installed at the same time. When one set of dust collecting bags 10 collects enough dust, the dust collecting bags 10 on the other side can be switched to collect dust, thereby ensuring the filtering effect. By providing a mounting ring 16 and a card slot 17 for use in conjunction, the sealing performance of the connection between the dust collecting bag 10 and the mounting cavity 9 is improved, thereby ensuring the filtering effect.

[0028] A moving seat 11 is fixedly installed in the middle of one side of the moving frame 4. The moving seat 11 is installed on the surface of the screw rod 12. The screw rod 12 is rotatably installed on the inner side of the support frame 8. One end of the screw rod 12 is transmission-connected to the output end of the motor 13. The motor 13 is fixedly installed on one side of the support frame 8. A slide 14 is fixedly installed on the top and bottom of one side of the moving frame 4. The slide 14 is slidably installed on the surface of the slide rod 15. Both ends of the slide rod 15 are fixedly connected to the support frame 8.

[0029] By setting up a motor 13, the output end of the motor 13 can drive the screw rod 12 to rotate, so that the movable seat 11 can be used to move, and the movable seat 11 drives the movable frame 4 to move, which is convenient for switching to another set of dust collecting bags 10 for use, and also convenient for taking out the dust collecting bags 10 that have collected dust for cleaning. When one set of dust collecting bags 10 is being cleaned, the other set of dust collecting bags 10 can collect dust normally, thereby ensuring that the surface grinder body 1 can work normally and improving the processing efficiency.

[0030] When in use, the device is moved to a designated position, and the exhaust fan 7 is started. The exhaust fan 7 quickly extracts the air in the installation cavity 9 through the exhaust hose 6, forming a negative pressure inside the installation cavity 9. The negative pressure in the installation cavity 9 sucks the dust and air in front of the dust hood 2 together through the dust suction hose 3. The dust is filtered by the dust collecting bag 10 and remains in the dust collecting bag 10. The air is discharged by the exhaust fan 7 through the dust collecting bag 10. When enough dust is collected in the dust collecting bag 10 currently in use, the motor 13 is started and the motor 13 is controlled to output The outlet end drives the screw rod 12 to rotate, and the rotating screw rod 12 causes the movable seat 11 to move, thereby driving the movable frame 4 to move, so that the movable frame 4 moves to align with another dust collecting bag 10, and the bottom of the dust suction hose 3 is aligned with the top opening of the installation cavity 9, and one end of the exhaust hose 6 is aligned with the bottom opening of the installation cavity 9, so that the dust is collected in another group of dust collecting bags 10. At the same time, as the movable frame 4 moves, the top opening of the previous group of installation cavities 9 is opened, and the operator can directly take out the dust collecting bags 10 filled with dust from the previous group for cleaning.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
