[0055] More specifically, with the development of society and the rise in industrialization, consumers are demanding higher quality, performance, and cost-effective equipment. Grinding equipment, as an indispensable component of modern industry, plays a significant role in industries such as food, chemicals, and pharmaceuticals. Common grinding equipment is noisy, significantly impacting the health of operators. A common way to reduce noise is to build a soundproof room, but the cost of such a room is unaffordable for most companies, not to mention the high price of the grinding equipment itself.

[0056] However, in the existing technology, the existing vertebral grinding equipment on the market has industry-leading functions and grinding efficiency, but its noise and cost control are unsatisfactory. When traditional grinding equipment is installed in a factory, the entire workshop will be in a state of excessive decibels. Long-term use in the factory has a great impact on workshop workers. Workers who are in this working environment for a long time will suffer from symptoms such as hearing loss, irritability, and decreased vision. Therefore, the technical solution involved in the embodiment of the present invention improves the structure of the grinding equipment based on the negative characteristics of the grinding equipment in the prior art, such as excessive noise, to solve the problem of high noise of the grinding equipment. Based on this, we analyzed the noise of the equipment and found that the noise is mainly transmitted to the outside world through the outer shell of the grinding equipment. Therefore, this solution optimizes and adjusts the outer shell of the grinding equipment. In addition, the outer shell manufacturing and processing cost in the prior art is high, the fitting surface of the fixed knife machine cover outer shell is processed as a whole, the structure is complex, and it is easy to deform. The processing area is difficult and the requirements for the lathe equipment are also high. The solution involved in the embodiment of the present invention also improves this problem. In the embodiment of the present invention, the outer shell of the grinding equipment includes a lower end flange 1 and an upper end flange 3, as well as a conical plate structure 2 welded between the lower end flange 1 and the upper end flange 3, and several fixed knife blocks (fixed knife structure 6). The above technical features are combined into a hollow frustum, which is fitted in the assembled welding grinding shell;

[0057] The upper and lower end surfaces of the fixed blade block (fixed blade structure 6) are respectively fixed by an upper limit flange 4 and a lower limit flange 5 through bolt locking.

[0058] Among them, the grinding equipment shell adopts a cavity design, and only the lower flange 1 and the upper flange 3 at the upper and lower ends are finely processed. The lower inner processing surface 13 and the upper inner processing surface 33 are used to support and fit the fixed knife, and the middle cavity (sound-absorbing cavity structure 7) is filled with sound insulation cotton, which plays the role of filling support and sound insulation, and can greatly reduce the equipment noise. This solves the problem of high noise in traditional grinding equipment. The structure of the shell adopts a finely processed lower flange (lower flange 1) and upper flange (upper flange 3), and welds a conical plate structure 2, which greatly reduces the processing difficulty. At the same time, it avoids the problem of uneven installation of the fixed knife due to the non-roundness of the fine processing error of the inner wall of the cone, and uneven distribution of grinding particles due to uneven gap with the moving knife. Better assembly accuracy can also extend the service life of the moving knife and the fixed knife.

[0059] It should be noted that in this embodiment, the skeleton welding process can significantly reduce processing costs. The thick upper flange 3 and lower flange 1 are less deformed by welding, which enhances assembly precision and increases the service life of the entire machine. The flange can be processed on a conventional lathe. The processing route is as follows: first, the upper flange 3 and lower flange 1 are fine-machined except for the conical surface. Then, the upper flange 3 and lower flange 1 are welded to the conical plate structure 2. Finally, the lower inner machined surface 13 and the upper inner machined surface 33 of the inner cavity are fine-machined on a lathe to ensure coaxiality.

[0060] Among them, the upper and lower end surfaces of the conical plate structure 2 are flattened, and the outer edge of the lower end surface reaches the cylindrical positioning surface 21, which is used for positioning and assembling the conical plate structure 2 and the lower end flange 1. Similarly, the lower end flange 1 also needs to be processed with a step (lower end outer positioning step 12). With this positioning step, welding workers can quickly complete the welding task as required with guaranteed quality and quantity, and there will be no problem of coaxiality difference.

[0061] Among them, the upper and lower ends of the fixed knife 6 are provided with an upper end inner positioning step structure 61 and a lower end inner positioning step structure 62, which are used to cooperate and fix with the upper limit flange 4 and the lower limit flange 5 of the upper limit flange first step 43 and the lower limit flange first step 53. This step fixing method is effective in locking and easy to disassemble and assemble.

[0062] In this embodiment, a gap is left between the horizontal plane of the upper limit flange 4 and the lower limit flange 5 and the upper end flange 3 and the lower end flange 1, usually 1-2MM, which is used as a pre-clamping gap for bolt locking to avoid the problem of loose clamping.

[0063] In this embodiment, the upper and lower limit flanges are provided with a finely machined upper flange first step 32 and a flange first step 14, and the upper and lower end face flanges are provided with a finely machined upper limit flange second step 42 and a lower limit flange second step 52; the upper limit flange and the upper end flange, the lower limit flange and the lower end flange are all positioned by cooperating with each other through steps.

[0064] In addition, it should be noted that the circular ring of the rolled steel plate can be cut from a hollow circular tube, and the grinding chamber can be processed as a whole. Although such an improvement increases the manufacturing cost, the strength and precision of the overall equipment are greatly improved.

[0065] In summary, the embodiment of the present invention relates to a shell structure of a grinding equipment, which adopts a cavity design. Its structure adopts the method of welding upper and lower fine-machined flanges to a general plate with a rolled cone. The middle cavity is filled with sound insulation cotton, which plays a role of filling support and sound insulation. Compared with the existing technology, it can greatly reduce the noise of the equipment, and the skeleton welding process can greatly reduce the processing cost. The thick upper and lower flanges are less deformed by welding, which enhances the assembly accuracy and improves the service life of the whole machine. Moreover, the flange can be processed by an ordinary lathe. First, the upper and lower flanges are fine-machined except for the conical surface, and then the upper and lower flanges are welded and fixed with the conical plate. Finally, the lathe is used to fine-machine the conical surface of the inner cavity flange to ensure coaxiality. In addition, the upper and lower ends of the fixed knife are provided with steps for cooperating and fixing with the steps of the upper and lower limit flanges. The step fixing method is effective in locking and convenient for disassembly and assembly. As described above, the solution involved in the embodiment of the utility model can greatly reduce equipment noise, solve the problem of high noise in traditional grinding equipment, and at the same time avoid the problem of uneven distribution of grinding particle size caused by unequal installation of fixed knife due to the non-circularity of the conical inner wall finishing error, thereby extending the service life of the movable knife and the fixed knife accordingly.

[0066] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
