Description

Technical Field

[0001] This utility model relates to the field of fabric processing, specifically a grinding mechanism for a slab deburring machine. Background Technology

[0002] A deburring machine is a device that removes burrs from the surface or edges of a workpiece using physical, chemical, or electrochemical methods. Currently, most deburring of slabs uses physical methods, where the slab is placed on a conveyor and slowly moved by the conveyor, transporting it to a position under a grinding roller. The high-speed rotating roller then contacts and grinds the burrs off the slab's surface.

[0003] However, during the grinding process of the aforementioned deburring machine, the slab receives poor grinding effect, the contact area between the grinding roller and the slab is small, and the grinding is done in one go. The conveyor cannot transport the slab too fast during the grinding process, which not only affects the grinding and deburring efficiency but also the grinding quality. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 In this embodiment of the present invention, a grinding mechanism for a slab deburring machine includes a base 1, a conveyor 2 installed at the upper end of the base 1, a mounting frame 3 arranged directly above the conveyor 2, a support frame 6 connected through the middle of the mounting frame 3, and lifting components 7 for driving the mounting frame 3 to rise and fall at both ends of the support frame 6; a grinding unit 4 is arranged at the lower end of the mounting frame 3.

[0023] The grinding unit 4 includes a gear disk 401. The middle bearing of the gear disk 401 is rotatably connected to a first rotating shaft 402. The lower end of the first rotating shaft 402 is fixedly connected to a connecting frame 403. Multiple second rotating shafts 404 are arranged circumferentially around the connecting frame 403. The multiple second rotating shafts 404 are equidistantly arranged around the periphery of the first rotating shaft 402. The second rotating shafts 404 are rotatably connected to the outer ends of the connecting frame 403 through bearings. The upper end of the second rotating shaft 404 is fixedly connected to a gear 405, which meshes with the gear disk 401. The lower end of the second rotating shaft 404 is fixedly connected to a grinding disk 406.

[0024] A drive assembly 5 for driving the first rotating shaft 402 to rotate is installed in the middle of the inner side of the mounting bracket 3. The drive assembly 5 includes a motor, the output end of which passes through the outer wall of the bottom end of the mounting bracket 3 and is fixedly connected to the first rotating shaft 402 through a coupling.

[0025] Two pressing components 8 are symmetrically distributed at both ends of the bottom of the mounting frame 3. The pressing components 8 include two connecting rods 801 that penetrate the bottom outer wall of the mounting frame 3. A rotating roller 802 is rotatably connected between the lower ends of the two connecting rods 801. The upper outer wall of the connecting rod 801 is threaded, and the upper end of the connecting rod 801 is fixedly connected to the mounting frame 3 by a nut. The lowest point of the rotating roller 802 is on the same horizontal line as the bottom end face of the grinding disc 406.

[0026] In this embodiment: because the grinding mechanism of the deburring machine results in poor grinding effect on the slab during the grinding process, with little contact area between the grinding roller and the slab, and the grinding is done in a single pass, the conveyor speed of the slab during the grinding process cannot be too fast, which not only affects the grinding and deburring efficiency but also the grinding quality. Therefore, this solution replaces the traditional grinding roller structure with a grinding unit 4, which not only expands the grinding contact area but also allows for multiple contact grinding of the grinding surface, thereby improving the grinding accuracy and greatly reducing the residual adhesion of burrs. In addition, the conveyor 2 can increase the conveying speed when transporting the slab, which not only does not delay the grinding quality but also speeds up the grinding efficiency.

[0027] Specifically, when the outer surface of the slab needs to be polished, the slab is first placed on the conveyor 2 for conveying. One end of the slab first contacts the pressing component 8, and then the pressing component 8 enters the lower part of the polishing unit 4. The first rotating shaft 402 is driven to rotate at high speed by the drive component 5. The rotating first rotating shaft 402 will drive the connecting frame 403 to rotate. The connecting frame 403 will also drive the polishing disc 406 to revolve around the first rotating shaft 402. At the same time, the gear 405 above the connecting frame 403 meshes with the gear plate 401 while revolving and rotating, thereby forcing the polishing disc 406 to rotate. The revolution and rotation of the polishing disc 406 are used to polish the same area of ​​the slab surface multiple times, improving the polishing accuracy and effectively reducing the residue of burrs. After the upper outer surface of the slab is polished, the slab can be flipped over to the other end for quick polishing to remove burrs.

[0028] It should be noted that the outer surface of the conveyor belt in conveyor 2 in this scheme is a rough surface.

[0029] Please refer to this carefully. Figures 1-4 The lifting assembly 7 is located on the base 1, and the lifting assembly 7 is a linear lifting module. The output end of the lifting assembly 7 is fixedly connected to the support frame 6 by bolts.

[0030] In this embodiment, the lifting component 7 is used to adjust the position and height of the grinding unit 4, which facilitates the grinding and deburring of slabs of different thicknesses and sizes. The grinding depth of the grinding unit 4 on the slab can also be adjusted according to the working conditions. The lifting height is precisely controlled, and the operation is convenient and quick.

[0031] Please refer to this carefully. Figures 1-4 The mounting bracket 3 has mounting grooves 31 at both ends of the middle section for the support bracket 6 to pass through. A buffer 32 is inserted between the support bracket 6 and the bottom of the mounting groove 31; the buffer 32 is a rubber pad.

[0032] In this embodiment: Due to the damping elasticity of the buffer 32, not only can the vibration transmission between the support frame 6 and the mounting frame 3 be reduced, but it can also compensate for the unevenness of the mounting frame 3 when there are imperceptible undulations in the mounting frame 3, such as when the slab itself is not flat. This ensures that the force of the grinding disc 406 against the slab remains constant, thus avoiding damage to the grinding disc 406 and the drive assembly 5 caused by rigid grinding.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
