DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: an ultrafine pulverizer for producing spherical graphite, comprising a support frame 1, a servo motor 4 is fixedly connected to the front side of the support frame 1, a crushing bin 3 is fixedly connected to the inner wall of the support frame 1, a transmission 2 is fixedly connected to the output end of the servo motor 4, a first output rod 5 is rotatably connected to the right side of the front end of the crushing bin 3, a plurality of crushing blades 7 are arranged on the outer wall of the first output rod 5, a second output rod 6 is rotatably connected to the left side of the front end of the crushing bin 3, a first gear 8 is fixedly connected to the front side of the outer wall of the first output rod 5, a second gear 9 is rotatably connected to the front side of the outer wall of the second output rod 6, and the first gear 8 is fixedly connected to the front side of the outer wall of the second output rod 6. A first pulley 20 is fixedly connected to one side of the outer wall of an output rod 5, a sorting box 10 is fixedly connected to the bottom of the crushing bin 3, a filter hole is arranged at the bottom of the sorting box 10, a filter hole is arranged at the top of the sieve plate 15, the filter hole spacing of the sieve plate 15 is larger than the filter hole spacing of the sorting box 10, a driving rod 12 is rotatably connected to the right side of the front end of the sorting box 10, a second pulley 11 is fixedly connected to the front side of the outer wall of the driving rod 12, a plurality of elliptical blocks 14 are fixedly connected to the middle part of the outer wall of the driving rod 12, a sieve plate 15 is rotatably connected to one side of the inner wall of the sorting box 10, and a quantitative component is arranged at the bottom of the sorting box 10.

[0031] Firstly, graphite is put into the crushing bin 3 through an external feeding device, and then the servo motor 4 is turned on and the torque enhancement of the transmission 2 drives multiple groups of crushing blades 7 to work in the crushing bin 3.

[0032] During the crushing process, as the first output rod 5 rotates, belts are sleeved on the outer walls of the second pulley 11 and the first pulley 20. The belt connection between the first pulley 20 and the second pulley 11 allows the driving rod 12 to rotate, so that the elliptical blocks 14 can rotate with the outer periphery and periodically and continuously lift the screen plate 15. Multiple elliptical blocks 14 are slidably connected to one side of the bottom of the screen plate 15. For some raw materials with a larger crushing volume, they will be discharged along the slope under the shaking of the screen plate 15, thereby fully improving the uniformity of the size of the crushed graphite raw materials and improving the overall crushing quality.

[0033] The first gear 8 is meshed with the second gear 9, and a plurality of crushing blades 7 are provided on one side of the outer wall of the second output rod 6. Through the meshing connection between the first gear 8 and the second gear 9, the first output rod 5 and the second output rod 6 rotate in opposite directions, thereby achieving the extrusion and crushing effect on the raw materials.

[0034] The input end of the transmission 2 is connected to the output end of the servo motor 4, and the output end of the transmission 2 is fixedly connected to the first output rod 5. By turning on the servo motor 4 and enhancing the torque of the transmission 2, multiple groups of crushing blades 7 are driven to work in the crushing bin 3.

[0035] Reference Figure 3-Figure 4 The quantitative component includes a conical guide cylinder 13, which is fixedly connected to the bottom of the sorting box 10. A fixed block 16 is fixedly connected to the middle of the outer wall of the support frame 1. A plurality of electric push rods 17 are fixedly connected to the inner wall of the fixed block 16. A slide plate 18 is fixedly connected to the output end of the electric push rod 17. A meter body 19 is provided on the top of the slide plate 18.

[0036] When the graphite raw materials that meet the size pass through the sieve plate 15 and the filter holes at the bottom of the sorting box 10 respectively, they will fall onto the detection table of the meter body 19 on the top of the slide plate 18. After reaching the preset weight, the PLC controls the electric push rod 17 to drive the slide plate 18 to retract, thereby achieving quantitative control of the graphite raw materials.

[0037] The slide plate 18 is slidably connected to the right side of the conical guide tube 13 to limit the position of one side of the slide plate 18 so that the raw material on the top of the meter body 19 can be squeezed out in cooperation with the conical guide tube 13 as the slide plate 18 withdraws.

[0038] Working principle:

[0039] In the process of producing spherical graphite, the ultrafine pulverizer is used to finely crush the graphite raw material. First, the graphite is put into the crushing bin 3 through an external feeding device. Then, the servo motor 4 is started, and under the torque enhancement effect of the transmission 2, multiple groups of crushing blades 7 are driven to perform the crushing task in the crushing bin 3. During the crushing process, the meshing connection between the first gear 8 and the second gear 9 ensures that the first output rod 5 and the second output rod 6 work in opposite rotation directions, thereby achieving effective extrusion and crushing of the raw materials.

[0040] In addition, as the first output rod 5 rotates, the first pulley 20 and the second pulley 11 are connected by a belt, which drives the rod 12 to start rotating, thereby causing the elliptical block 14 to rotate along its periphery. This periodic rotation causes the screen plate 15 to continuously rise, so that some of the larger volume of crushed materials are discharged along the slope under the action of the shaking of the screen plate 15. This process helps to improve the size uniformity and overall crushing quality of the graphite raw material after crushing.

[0041] When the size of the graphite raw materials meets the requirements and passes through the sieve plate 15 and the filter holes at the bottom of the sorting box 10, they will fall onto the measuring device body 19 detection table on the top of the slide plate 18. When the graphite raw materials on the detection table reach the preset weight, the PLC will control the electric push rod 17 to retract the slide plate 18, thereby achieving precise quantitative control of the graphite raw materials.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
