[0026] 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.
[0027] Example 1
[0028] To address the problem of reduced grinding rates caused by the difficulty in rapidly circulating and grinding materials in existing technologies, this embodiment provides a grinding mill with multiple fine grinding functions. Please refer to [link / reference]. Figures 1-5 This grinding mill, equipped with a screening structure, can quickly and cyclically feed substandard materials, reducing the labor intensity of workers and improving the grinding quality of materials. It includes a splash guard 2 mounted on the grinding chamber 1. Inside the grinding chamber 1, there are collection troughs distributed below one end of the screening plate 33 and corresponding to the position of the collection hood 47, facilitating material collection and improving the automatic feeding effect. The grinding chamber 1 is equipped with a powder screening mechanism 3 and a circulating grinding mechanism 4 for repeated material grinding. The screening mechanism 3 can screen materials, improving the production quality, while the circulating grinding mechanism 4 can repeatedly grind the materials, improving the grinding effect.
[0029] In the process of grinding materials, in order to quickly and repeatedly grind the materials and improve the grinding effect, the circulating grinding mechanism 4 includes a drive motor 41 mounted on the grinding box 1. The output end of the drive motor 41 is connected to a grinding roller 42 that is rotatably connected to the grinding box 1. A drive gear 43 is mounted on the grinding roller 42. Two sets of grinding rollers 44 are rotatably connected inside the grinding box 1. A connecting gear 45 is mounted on the grinding roller 44. The other set of grinding rollers 44 is connected to the connecting gear 45 and the drive gear 43. The grinding chamber 1 is equipped with a collection cover 47, a rotary motor 48 is installed at the bottom of the collection cover 47, a conveyor 49 is connected to the output end of the rotary motor 48, a feeding cylinder 410 is installed at the top of the collection cover 47, and a guide plate 411 is installed at the top inside the grinding chamber 1. The guide plate 411 is distributed at an angle directly above the first grinding roller 42 and the second grinding roller 44, so that the conveyed material can flow accurately between the first grinding roller 42 and the second grinding roller 44, thereby improving the grinding precision and the grinding quality. The operation of the drive motor 41 drives the first grinding roller 42, which in turn causes the drive gear 43 to rotate. Under the meshing of the linkage gear 46 and the connecting gear 45, the two sets of second grinding rollers 44 rotate synchronously, thereby finely grinding the material. After grinding, the powder that does not meet the requirements is screened out by the screening plate 33 and flows into the collection hood 47. The operation of the rotary motor 48 drives the conveyor 49 to rotate, thereby quickly conveying the unacceptable material back to the top of the feeding cylinder 410. With the support of the guide plate 411, the conveyed material falls between the first grinding roller 42 and the second grinding roller 44, thus allowing the material to be ground in a cycle, improving the grinding effect.
[0030] Example 2
[0031] Based on Example 1, such as Figures 1-5 As shown, based on the problem that existing technologies do not allow for rapid and efficient material grinding and thus reduce the grinding rate, and because existing grinding equipment typically lacks a screening function, it is difficult to guarantee the fineness of the grinding after grinding. This can easily lead to the mixing of insufficiently processed products, affecting the production quality of the materials. Therefore, this device is also equipped with a structure for screening qualified materials.
[0032] In the grinding process of materials, in order to screen out powder of better quality and improve the production quality of materials, the screening mechanism 3 includes limiting members 31 fixedly installed inside the grinding chamber 1. The limiting members 31 are distributed in pairs on the inner wall of the grinding chamber 1 in a staggered manner, so that the screening plate 33 can screen the materials, improving the screening effect. A buffer spring 32 is connected to the limiting member 31, and the screening plate 33 connected to the buffer spring 32 is slidably connected to the limiting member 31. The screening plate 33 is distributed at an angle inside the grinding chamber 1, which facilitates the collection of unqualified materials and allows for the cyclical grinding of materials, improving the grinding efficiency. The grinding chamber 1 is equipped with an anti-clogging component 301 to prevent material from clogging the screening plate 33. Under the limiting of the limiting members 31 and the buffer spring 32, the screening plate 33 screens the powder, improving the production quality of materials.
[0033] In the process of screening powder, in order to prevent powder from clogging the screening plate 33 and improve the screening effect, the anti-clogging component 301 includes a fixed disk 3011 installed at the output end of the drive motor 41. The diameter of the fixed disk 3011 is smaller than the diameter of the drive disk 3014, so that the drive disk 3014 can be driven to rotate stably under the connection of the connecting belt 3012. The fixed disk 3011 is connected to the connecting belt 3012. A rotating rod 3013 is rotatably connected to the grinding box 1. The drive disk 3014 connected to the connecting belt 3012 is installed on the rotating rod 3013. A vibrating element 3015 is installed on the rotating rod 3013. The position of the vibrating element 3015 corresponds to that of the pad 3016, so that the vibrating element 3015 can continuously strike the pad 3016, thereby improving the anti-clogging performance. The bottom of the screening plate 33 is equipped with a pad 3016. The pad 3016 is made of rubber and plays a protective role for the screening plate 33. The operation of the drive motor 41 drives the fixed disk 3011 to rotate. With the connection of the connecting belt 3012 and the drive disk 3014, the rotating rod 3013 rotates, thereby mobilizing the vibrating element 3015 to continuously strike and vibrate the pad block 3016, which improves the efficiency of powder screening.
