Description

Technical Field

[0001] This utility model relates to the field of dust collection technology for polishing machines, specifically a dust collection device for polishing machines. Background Technology

[0002] Polishing machines, also known as grinding machines, are often used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. Due to the combined action of the polishing disc and polishing compound, and the friction against the surface to be polished, paint contamination, oxidation layers, and shallow scratches can be removed.

[0003] Polishing machines generate a lot of dust during the polishing process. In existing technology, a dust collection hood is usually placed over the polishing area to absorb the dust. However, this design is prone to clogging due to the numerous suction pipes. Once the pipes are clogged, the dust collection hood needs to be removed for unblocking, which is inefficient.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. 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.

[0026] 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 illustrating the device structure may be partially enlarged, not adhering 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.

[0027] 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.

[0028] This utility model provides a dust collection device for a polishing machine. Through the cooperation of the dust collection and processing components and the centralized unclogging component, the multiple dust suction holes inside the dust collection cover can be cleaned one by one without removing the dust cover each time the polishing machine is used, thus avoiding clogging and making it convenient to use.

[0029] Figures 1-4 The diagram shown is an overall structural schematic of an embodiment of the dust collection device for a polishing machine according to this utility model. Please refer to [link / reference]. Figures 1-4 The main structure of this embodiment includes: a dust collection and treatment component and a centralized unblocking component.

[0030] The dust collection and treatment assembly is used for centralized dust collection. Specifically, the dust collection and treatment assembly includes a dust collection and treatment cover 11, a through hole 12 on the top surface of the dust collection and treatment cover 11, a guide hole 13 on the top surface of the dust collection and treatment cover 11, an annular hollow frame 14 above the dust collection and treatment cover 11, a plate 15 fixed inside the annular hollow frame 14, a positioning hole 16 on the plate 15, a suction pipe 17 connected to the bottom surface of the first annular plate 21, and a suction hose 18 connected to the top surface of the annular hollow frame 14. The dust collection and treatment assembly also includes a cylinder 19 fixed to the top surface of the dust collection and treatment cover 11.

[0031] In practical use, the transmission shaft of the polishing machine passes through the cylinder 19, and the polishing disc connected to the end of the transmission shaft is located below the dust collection cover 11. During use, the suction hose 18 is connected to the external vacuum cleaner. At this time, dust is sucked through several distributed suction pipes 17, and finally the dust is absorbed into the external vacuum cleaner. The flat plate 15 is attached to the top surface of the dust collection cover 11. The flat plate 15 is locked by bolts through the positioning holes 16, so that the annular hollow frame 14 can be directly disassembled and replaced from the outside. The split structure design makes it convenient to replace and maintain without disassembling the entire dust collection cover 11.

[0032] The centralized unblocking assembly is used to centrally unblock the suction pipe 17. Specifically, the centralized unblocking assembly includes a first annular plate 21 set above the dust collection treatment cover 11, a guide post 22 fixed to the bottom surface of the first annular plate 21, a spring 23 sleeved with the guide post 22, a side ear 25 fixed to the end of the guide post 22, a second annular plate 24 connected to the side ear 25, and a clearing rod 26 fixed to the top surface of the second annular plate 24.

[0033] In practical use, when the spring 23 is in its original state, the unblocking rod 26 is separated from the vacuum pipe 17. At this time, the user pulls the first annular plate 21 upward, the first annular plate 21 moves upward, and the spring 23 is stretched. During the upward movement of the first annular plate 21, the first annular plate 21 drives several unblocking rods 26 to move upward. The unblocking rods 26 are directly inserted into the vacuum pipe 17 to unclog the pipe. After the unblocking is completed, the user simply drops the first annular plate 21. At this time, the spring 23 contracts, directly causing the unblocking rods 26 to separate from the vacuum pipe 17. At this time, the unblocking is completed. Each time the polishing vacuum is blocked, it can be cleared by simply pulling it outward, which is convenient to use.

[0034] Furthermore, it also includes a positioning component, which includes a concave frame 31 fixed to the top surface of the dust collection and treatment cover 11, a round shaft 32 disposed in the concave frame 31, and a sleeve 33 fitted with the round shaft 32; the positioning component also includes L-shaped hooks 34 and a base plate 35 fixed on both sides of the sleeve 33.

[0035] In practical use, during the pressing down of the annular hollow frame 14, the flat plate 15 presses directly onto the base plate 35. The base plate 35 moves down, and at this time, the base plate 35 drives the sleeve 33 to rotate along the circular shaft 32 until the L-shaped hook 34 presses onto the flat plate 15, thereby completing the locking and positioning, and preventing the bolts locking the flat plate 15 from loosening and falling off, which would cause the flat plate 15 to shift.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
