Technical Field

[0001] The invention relates to the technical field of control cabinets, in particular to a grinding machine with a self-cleaning function. Background Art

[0002] A grinder is a device used to grind, crush, or polish workpieces or materials, and is widely used in industrial production. Using a grinding disc, wheel, or other abrasive tool, it utilizes friction, collision, and shear forces to transform materials into the desired fine powder or precision surface. Grinding machines include disc-type, rotary shaft-type, and specialized grinders. These grinders can process complex shapes, such as planes, cylinders, and spheres, with high precision and a wide range of applications.

[0003] However, the fine particles and residues produced during the grinding process often adhere to the internal structure of the machine. Currently, these impurities are cleaned manually, which has poor cleaning effects and low efficiency. Summary of the Invention

[0020] See also Figure 1-4 The present invention provides a technical solution: a grinder with a self-cleaning function, comprising a grinding cylinder 1, two connecting seats 2, a protective cover 3 and a cleaning structure 5. The two connecting seats 2 are fixedly arranged on the left and right sides of the outside of the grinding cylinder 1, and both connecting seats 2 are provided with internal threads. Mounting holes are provided on the left and right sides of the protective cover 3, and the mounting holes correspond to the internal threads of the connecting seats 2. The protective cover 3 is connected to the connecting seat 2 by a first bolt 4. A sealed cleaning space is formed between the protective cover 3 and the grinding cylinder 1, and a cleaning structure 5 is provided on the protective cover 3.

[0021] Specifically, the cleaning structure 5 includes a delivery pipe 51, a water inlet pipe 52, a motor 53, a first bevel gear 54, a second bevel gear 55, a cleaning pipe 56 and a plurality of nozzles 57. The delivery pipe 51 is rotatably connected to the top of the protective cover 3. One end of the water inlet pipe 52 is connected to the delivery pipe 51 through a sealed bearing. The outer ring of the sealed bearing is fixedly connected to the inner wall of the delivery pipe 51. The inner ring of the sealed bearing is interference fit with the outer wall of the water inlet pipe 52. The motor 53 is fixedly arranged on the outer top of the protective cover 3. The first bevel gear 54 is fixedly connected to the driving end of the motor 53. The motor 53 is used to drive the first bevel gear 54. The second bevel gear 55 is fixedly arranged on the delivery pipe 51. The second bevel gear 55 is meshed with the first bevel gear 54. The cleaning pipe 56 is fixedly arranged on the delivery pipe 51 and is communicated with the delivery pipe 51. A plurality of nozzles 57 are fixedly arranged on the cleaning pipe 56.

[0022] Specifically, one end of two connecting rods 6 is fixedly provided on the outer wall of the delivery pipe 51 , and a connecting assembly 8 is provided on the other end of the connecting rod 6 . A scraper 7 is also provided on the connecting assembly 8 , and the scraper 7 is used to scrape the inner wall of the grinding cylinder 1 .

[0023] Specifically, the connecting assembly 8 includes a groove 81 and a second bolt 82. The groove 81 is movably mounted on the connecting rod 6, and a threaded groove is provided on the top of the groove 81 and the connecting rod 6. The groove 81 and the connecting rod 6 are connected by the second bolt 82. The connecting assembly 8 can enable the connecting rod 6 and the scraper 7 to be quickly disassembled and assembled, which is convenient for subsequent maintenance.

[0024] Specifically, the scraper 7 is an L-shaped structure, which can better fit the inner wall curved surface and enhance the scraping effect.

[0025] Working Principle: During operation, an external water supply device delivers water into the delivery pipe 51 through the water inlet pipe 52. Subsequently, the motor 53 is activated, and its driving end rotates the first bevel gear 54 fixed to it. The first bevel gear 54 then meshes with the second bevel gear 55 fixed to the delivery pipe 51, thereby driving the delivery pipe 51, the cleaning pipe 56 fixed thereto, and the multiple nozzles 57. At the same time, the water inlet pipe 52 inputs cleaning liquid, which enters the cleaning pipe 56 connected to the delivery pipe 51 through a sealed bearing. Under pressure, the cleaning liquid is sprayed from the multiple nozzles 57 fixed to the cleaning pipe 56 at high speed onto the inner wall of the grinding cylinder 1, providing a preliminary flushing. Due to the configuration of the sealed bearing, the water inlet pipe 52 does not rotate when the delivery pipe 51 rotates. The two connecting rods 6 fixed to the outer wall of the delivery pipe 51 rotate with the delivery pipe 51. The connecting assembly 8 (including the groove 81 and the second bolt 82) at the other end of the connecting rod 6 also rotates synchronously. The connecting assembly 8 drives the L-shaped scraper 7 attached thereto to scrape the inner wall of the grinding cylinder 1. The rotating nozzle 57 continuously changes its flushing angle, cooperating with the rotating L-shaped scraper 7 to repeatedly scrape the inner wall. The two work synergistically to effectively remove residue and fine particles adhering to the inner wall of the grinding cylinder 1, achieving a self-cleaning function. As the scraper 7 rotates and scrapes, its L-shaped structure better conforms to the curved surface of the inner wall, enhancing the scraping effect. The connecting assembly 8 allows for quick assembly and disassembly of the scraper 7, facilitating subsequent maintenance.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
