Description

Technical Field

[0001] This utility model relates to a polishing machine, and more particularly to a dustproof polishing machine. Background Technology

[0002] Polishing machines are widely used in the surface treatment of metals, stone, wood, and composite materials. They use a high-speed rotating polishing disc or abrasive wheel to grind and polish the surface of workpieces to achieve the required surface finish and shape accuracy. With the increasing demands for industrial automation and high-precision machining, the power and speed of polishing machines are constantly increasing, resulting in the generation of a large amount of dust, abrasive chips, and small fragments during operation.

[0003] The air intake of polishing machines is usually directly connected to the internal motor and electronic controller, lacking an effective dust prevention device. Dust and debris can easily enter the machine casing under high-pressure airflow or suction, adhering to the motor fan blades, winding surfaces, and heat sinks, leading to decreased heat dissipation performance and frequent motor thermal failures. At the same time, dust entering the electronic component area can also cause poor contact, short circuits, or control system malfunctions, and in severe cases, even cause the entire machine to stop or be scrapped, affecting production efficiency and equipment lifespan.

[0004] Currently, although some polishing machines on the market have been equipped with dust filters, filter sponges, or activated carbon filters at the air inlet or outlet, most of these are disposable devices and cannot be replaced or cleaned without disassembling the main unit casing. Utility Model Content

[0005] A dustproof polishing machine is disclosed, wherein a dustproof mesh cover is installed at the air inlet of the main unit, and a dustproof mesh is installed between the dustproof mesh cover and the air inlet. The dustproof mesh cover is removable and the dustproof mesh is replaceable. This invention provides a simple, easy-to-maintain, and highly effective dustproof polishing machine by installing a removable dustproof mesh cover at the air inlet of the main unit and a dustproof mesh between it and the air inlet. This solves the problem of existing polishing machines easily drawing in dust and debris through the air inlet, leading to damage to internal components such as the motor and controller, unstable operation, and difficult maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dustproof polishing machine has a dustproof mesh cover plate installed at the air inlet of the main unit, and a dustproof mesh is installed between the dustproof mesh cover plate and the air inlet. The dustproof mesh cover plate can be removed and the dustproof mesh can be replaced.

[0008] Further modifications include an air intake grille and connecting posts at the main unit's air intake.

[0009] Further details include: an air inlet window, a buckle, and a connecting hole, which is connected to the connecting post.

[0010] Further details include: a buckle notch, a connecting post notch, and an air inlet mesh. The buckle notch is positioned to correspond to the buckle position, the connecting post notch is positioned to correspond to the connecting hole position, and the air inlet mesh is positioned to correspond to the air inlet window position.

[0011] Further, the clips securely fasten the dust filter plate to the air intake of the main unit. When the dust filter needs to be replaced, simply remove the clips to detach the dust filter plate from the main unit and replace it with the dust filter plate located between the dust filter plate and the air intake grille.

[0012] This utility model provides a dustproof polishing machine with a simple structure, convenient maintenance, and good protective effect by setting a detachable dustproof mesh buckle plate at the air inlet of the main unit and setting a dustproof mesh between it and the air inlet. It solves the problem that existing polishing machines are prone to sucking in dust and debris at the air inlet during use, which leads to damage to internal components such as motors and controllers, unstable operation, and difficult maintenance.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views of the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown: This utility model provides a dustproof polishing machine, including a main unit 1, an air inlet grille 11, a connecting column 12, a dustproof mesh cover 2, and a dustproof mesh 3. The main unit 1 has an annular air inlet grille 11 around its air inlet for introducing cooling air; a connecting column 12 is provided at the air inlet grille 11, the connecting column 12 being a columnar protrusion with a neck, used to position and connect the dustproof mesh cover 2.

[0024] Preferably, the dustproof mesh cover 2 is a plate-shaped component that conforms to the contour of the air inlet, and has an air inlet window 21 corresponding to the air inlet grille 11. The edge of the dustproof mesh cover 2 is provided with several clips 22, which are elastically fastened to the outer edge of the air inlet of the main unit 1 or the outer ring of the air inlet grille 11, enabling detachable assembly of the cover and the main unit. The dustproof mesh cover 2 also has connecting holes 23 that mate with connecting posts 12. During assembly, the connecting holes 23 engage with the connecting posts 12 to assist in positioning.
