[0002] Silica powder is a non-toxic, odorless, and pollution-free inorganic non-metallic material. Due to its good dielectric properties, chemical stability, and high heat resistance, it is widely used in multiple fields such as electronic packaging, ceramics, and coatings. In the preparation process of silica powder, ball milling and pulverizing is one of the key processes, and its purpose is to pulverize the silica powder raw material to the required particle size.

[0003] However, during the use of existing devices, the following deficiencies exist: For existing ball milling and pulverizing equipment, it is not convenient to adjust the position of the grinding balls. During the long-term grinding of silica powder raw materials, the grinding balls and the bottom wall of the equipment are worn, resulting in an increase in the gap between the grinding balls and the bottom wall of the equipment. As a result, the fineness of the silica powder grinding decreases, the grinding quality is reduced, and the use effect is poor.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the adjustable ball milling mechanism in the present invention, the first servo motor drives the one-way threaded rod to rotate. The first bevel gear threadedly installed on the one-way threaded rod moves downward along the one-way threaded rod under the limitation of the fixed rod. The first bevel gear drives the rotating rod and the grinding balls to move through the rotating block and the fixed block. The four limiting rods cooperate with the connecting block to ensure the stable movement of the grinding balls. When the gap between the grinding balls and the bottom wall of the equipment increases due to wear, the positions of the four grinding balls can be adjusted simultaneously to keep a proper distance between the four grinding balls and the annular grinding disc, ensuring the fineness of silicon micropowder grinding and avoiding the reduction of grinding quality due to gap problems. This solves the problem that the existing ball milling and crushing equipment is not convenient to adjust the position of the grinding balls, resulting in wear between the grinding balls and the bottom wall of the equipment during long-term grinding of silicon micropowder raw materials, increasing the gap between the grinding balls and the bottom wall of the equipment, thus reducing the fineness of silicon micropowder grinding and the grinding quality.

[0017] 2. Through the collaborative work of the crushing mechanism and the spacing-adjusting and crushing-optimizing mechanism in the present invention, the double-shaft motor drives the two crushing rollers to rotate through the spline shaft and the sleeve. The crushing teeth on the crushing rollers initially crush the silicon micro-powder raw material. During the long-term crushing process, the crushing teeth will wear, resulting in an increase in the spacing between the two crushing rollers, which affects the crushing effect. However, the third servo motor drives the bidirectional threaded rod to rotate, causing the two moving frames to drive the sliders to move, and thus the spacing between the two crushing rollers can be adjusted conveniently and accurately. The spacing between the two crushing rollers can be adjusted in a timely manner according to the wear of the crushing teeth, ensuring that the silicon micro-powder raw material can always be fully crushed, and improving the crushing efficiency of the equipment.

[0018] 3. By setting up the feeding anti-blocking mechanism in the present invention, when the double-shaft motor works, it drives the rotating shaft to rotate through the sixth bevel gear, and the feeding plate on the rotating shaft rotates accordingly, timely separating the crushed silicon micro-powder from the bottom of the crushing shell to prevent material accumulation from blocking the feeding channel. At the same time, the conical feeding hopper cooperates with the filter holes on the annular grinding disc, enabling the crushed silicon micro-powder to smoothly fall into the discharge frame and be discharged, effectively avoiding problems such as equipment shutdown and cleaning caused by feeding blockage, ensuring the continuous and stable operation of the equipment, improving production efficiency, and reducing the manual maintenance cost.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] like Figure 4 and Figure 9 As shown, the crushing mechanism 4 includes four slide grooves 401, and the four slide grooves 401 are opened on the inner side of the crushing shell 2. Four sliders 402 are slidably connected in the four slide grooves 401, and two crushing rollers 403 are rotatably connected between the four sliders 402. The outer surfaces of the two crushing rollers 403 are fixedly connected with multiple crushing teeth 404. By arranging the matching structure of the four slide grooves 401 and the sliders 402 on the inner side of the crushing shell 2, a stable installation and movement basis is provided for the two crushing rollers 403. The sliders 402 slide in the slide grooves 401, so that the crushing rollers 403 can maintain stable operation when rotating to crush the silicon micropowder raw materials, reduce shaking, and avoid the problem of poor crushing effect due to the instability of the crushing rollers 403. At the same time, multiple crushing teeth 404 are evenly distributed on the outer surface of the crushing roller 403, which increases the contact area with the silicon micropowder raw material, enhances the crushing effect, improves the crushing efficiency, and ensures that the silicon micropowder raw material can be fully crushed.

[0024] like Figure 4 and Figure 9As shown, two fixing plates 405 are fixedly connected to one side of the crushing shell 2. A spline shaft 406 is rotatably connected between the two fixing plates 405. Two sleeves 407 are slidably connected to the outer surface of the spline shaft 406. One end of two crushing rollers 403 movably penetrates through two of the sliders 402. Four fourth bevel gears 408 are fixedly connected to the outer surfaces of one end of the two crushing rollers 403 and the two sleeves 407. The four fourth bevel gears 408 are meshed. The two fixing plates 405 play a role in firmly supporting the spline shaft 406, ensuring the stability of the rotation of the spline shaft 406. The sliding connection mode between the spline shaft 406 and the sleeve 407 enables the two crushing rollers 403 to move synchronously during the spacing adjustment, ensuring the accuracy of the relative positions between the crushing rollers 403. The four fourth bevel gears 408 are meshed with each other, realizing the stable transmission of the power of the double-shaft motor 410 to the two crushing rollers 403, ensuring that the two crushing rollers 403 can work cooperatively at a suitable rotational speed and direction, further improving the stability of the crushing operation and the crushing effect, and enabling the silicon micro-powder raw material to be evenly crushed.

[0025] As Figure 4 and Figure 9 shown, two support blocks 409 are rotatably connected to the outer surfaces of the two sleeves 407. The two support blocks 409 are fixedly connected to two of the sliders 402. A double-shaft motor 410 is fixedly installed on one side of the crushing shell 2. Two fifth bevel gears 411 are fixedly connected to the outer surface of the first output end of the double-shaft motor 410 and the outer surface of the spline shaft 406. The two fifth bevel gears 411 are meshed. A raw material conveyor 412 is installed on the top of the crushing shell 2. By rotatably connecting the support blocks 409 with the sleeves 407 and fixedly connecting them with the sliders 402, an additional supporting force is provided for the sleeves 407 and the crushing rollers 403, enhancing the stability of the rotation of the crushing rollers 403 and reducing the equipment wear caused by uneven stress. The double-shaft motor 410 is connected to the spline shaft 406 through the fifth bevel gears 411, realizing the efficient transmission of power, ensuring that the two crushing rollers 403 can obtain stable and sufficient power for the crushing work. The setting of the raw material conveyor 412 can convey the silicon micro-powder raw material into the crushing shell 2, ensuring the continuity of the crushing operation, avoiding affecting the production efficiency due to untimely raw material supply, and making the whole crushing process more automated and efficient.

[0026] As Figure 1 、 Figure 4 and Figure 8As shown, the spacing adjustment and crushing optimization mechanism 5 includes a fixed housing 501. The fixed housing 501 is fixedly connected to one side of the crushing housing 2. A bidirectional threaded rod 502 is rotatably connected inside the fixed housing 501. A limiting groove 503 is formed at the bottom of the fixed housing 501. Two moving frames 504 are threadedly installed on the outer surface of the bidirectional threaded rod 502. The fixed housing 501 provides an installation space and a support structure for the bidirectional threaded rod 502 and the moving frames 504, ensuring the stability of the spacing adjustment process. The threaded connection between the bidirectional threaded rod 502 and the moving frames 504 enables the two moving frames 504 to move towards or away from each other along the threaded rod when the third servo motor 505 drives the bidirectional threaded rod 502 to rotate, thereby realizing the precise adjustment of the spacing between the two crushing rollers 403. The limiting groove 503 plays a limiting role for the moving frames 504, preventing the moving frames 504 from shifting during movement and ensuring the accuracy of the spacing adjustment. It can timely and precisely adjust the spacing between the crushing rollers 403 according to the characteristics of the silica powder raw material and the wear condition of the crushing teeth 404, optimizing the crushing effect.

[0027] As Figure 4 , Figure 8 and Figure 9 As shown, the two moving frames 504 are fixedly connected to two other sliders 402, and the two moving frames 504 movably penetrate through the limiting groove 503. A third servo motor 505 is fixedly installed on one side of the fixed housing 501. The output end of the third servo motor 505 movably penetrates through the fixed housing 501 and is fixedly connected to the smooth end of the bidirectional threaded rod 502. By fixedly connecting the moving frames 504 to the sliders 402, the power of the third servo motor 505 is transmitted to the sliders 402, thereby driving the crushing rollers 403 to move and realizing the spacing adjustment. The third servo motor 505 provides power for the spacing adjustment. Its precise speed and steering control, combined with the transmission of the bidirectional threaded rod 502, can achieve a small and precise adjustment of the spacing between the crushing rollers 403. Even when the crushing teeth 404 are slightly worn, the spacing can be adjusted in time to ensure that the crushing effect is not affected. Compared with manual adjustment, it is more efficient and accurate, improving the intelligence level of the equipment and the stability of the crushing operation.

[0028] As Figure 4 and Figure 9As shown, the blanking anti-blocking mechanism 6 includes a rotating shaft 601. The rotating shaft 601 is rotatably connected inside the crushing shell 2. Three feeding plates 602 are fixedly connected to the outer surface of the rotating shaft 601. One end of the rotating shaft 601 movably penetrates the crushing shell 2. Two sixth bevel gears 603 are fixedly connected between one end of the rotating shaft 601 and the second output end of the double-shaft motor 410. The two sixth bevel gears 603 are meshed. By driving the rotating shaft 601 to rotate through the second output end of the double-shaft motor 410 via the sixth bevel gears 603, the effective utilization of power is realized, and the blanking anti-blocking mechanism 6 can be driven to work without an additional power source. During the rotation of the three feeding plates 602 fixed on the rotating shaft 601, the silicon micro-powder at the bottom of the crushing shell 2 can be timely separated in all directions, preventing material accumulation. The evenly distributed feeding plates 602 ensure the uniformity and comprehensiveness of feeding, avoiding local blockage, ensuring that the crushed silicon micro-powder can smoothly pass through the blanking channel, guaranteeing the continuous and stable operation of the equipment, and reducing the downtime maintenance time and cost caused by blanking blockage.

[0029] As Figure 1 , Figure 5 , Figure 6 and Figure 7 shown, four second bevel gears 311 are meshed with the first bevel gear 306. The annular grinding disc 301 is fixedly connected inside the grinding cylinder 1. A plurality of filter holes 318 are formed in the inner bottom of the annular grinding disc 301. A discharge frame 319 is fixedly connected inside the grinding cylinder 1. The discharge frame 319 penetrates the grinding cylinder 1. The one-way threaded rod 304 movably penetrates the discharge frame 319, and the discharge frame 319 is inclined. By meshing the four second bevel gears 311 with the first bevel gear 306, the transmission of the power of the first servo motor 314 to the grinding balls 310 is realized, ensuring that the grinding balls 310 can synchronously adjust their positions as the first bevel gear 306 moves, maintaining the grinding effect. The filter holes 318 in the inner bottom of the annular grinding disc 301 can screen the ground silicon micro-powder, and only the silicon micro-powder meeting the particle size requirements can pass through the filter holes 318 and fall into the discharge frame 319 for discharge, improving the quality of the finished silicon micro-powder. The inclined discharge frame 319 enables the silicon micro-powder to flow out smoothly under the action of gravity, avoiding material residue in the grinding cylinder 1, ensuring the smoothness of discharging, and improving the working efficiency and practicability of the equipment.

[0030] As Figure 5 , Figure 6 and Figure 7As shown, at the output end of the first servo motor 314 and the bottom end of the one-way threaded rod 304, there are two third bevel gears 315 fixedly connected. The two third bevel gears 315 are meshed and connected. Through the meshed connection of the two third bevel gears 315, the power of the first servo motor 314 is stably transmitted to the one-way threaded rod 304, ensuring that the one-way threaded rod 304 can rotate stably. Through bevel gear transmission, the direction of force transmission can be changed to a certain extent, making the installation position of the first servo motor 314 more flexible. At the same time, the stability of the transmission is enhanced, ensuring that the first bevel gear 306 can move smoothly up and down under the drive of the one-way threaded rod 304, thereby realizing the precise adjustment of the position of the grinding ball 310 and guaranteeing the smooth progress of the silicon micro-powder grinding work.

[0031] As Figure 1 , Figure 6 and Figure 7 As shown, at the bottom of the grinding cylinder 1, a second servo motor 316 is fixedly installed. The output end of the second servo motor 316 movably penetrates through the grinding cylinder 1 and is fixedly connected with a drive shaft 317. The top end of the drive shaft 317 movably penetrates through the dust-proof housing 303, the discharge frame 319, and the first bevel gear 306. The top end of the drive shaft 317 is fixedly connected with the conical feed hopper 302. An air cleaner 7 is installed on the outer surface of the grinding cylinder 1. The second servo motor 316 drives the conical feed hopper 302 to rotate through the drive shaft 317, so that the silicon micro-powder entering the grinding cylinder 1 can be evenly dispersed on the annular grinding disc 301, avoiding the concentrated accumulation of silicon micro-powder in a certain area. At the same time, the grinding ball 310 rotates with the conical feed hopper 302, and the second bevel gear 311 on the rotating rod 309 rotates around the first bevel gear 306, so that the rotating rod 309 rotates around its own axis while revolving, making the grinding ball 310 rotate around its own axis while revolving with the rotating rod 309, ensuring that the grinding ball 310 can comprehensively and evenly grind the silicon micro-powder, improving the grinding effect and efficiency. The setting of the air cleaner 7 can timely adsorb the dust generated during the grinding process, reducing the diffusion of dust inside the equipment and in the working environment. This not only improves the working environment and guarantees the physical health of the operators, but also prevents dust accumulation from affecting the normal operation of the equipment, prolongs the service life of the equipment, and improves the safety of equipment operation.

[0032] Usage method and working principle of this device: In the initial crushing stage of raw materials, the raw material conveyor 412 conveys the silicon micro-powder raw materials to the crushing shell 2. The double-shaft motor 410 is started, and its first output end transmits power to the spline shaft 406 through two meshed fifth bevel gears 411, making the spline shaft 406 rotate. The spline shaft 406 and the sleeve 407 are connected by splines, ensuring that the sleeve 407 rotates synchronously with the spline shaft 406 and can slide axially on the spline shaft 406. The sleeve 407 drives two crushing rollers 403 to rotate towards each other through four meshed fourth bevel gears 408, thereby squeezing and shearing the silicon micro-powder raw materials.

[0033] In the blanking anti-blocking stage, the second output end of the double-shaft motor 410 drives the rotating shaft 601 to rotate through the sixth bevel gear 603, and the three material deflectors 602 on the rotating shaft 601 rotate accordingly, timely deflecting the silica powder at the bottom of the crushing shell 2 to prevent material accumulation from blocking the blanking channel, ensuring that the crushed silica powder smoothly enters the grinding cylinder 1.

[0034] In the ball milling processing stage, by starting the second servo motor 316, its output end drives the drive shaft 317 to rotate, and the drive shaft 317 drives the conical feed hopper 302 to rotate, so that the silica powder is evenly dispersed on the annular grinding disc 301. At the same time, the grinding balls 310 rotate with the conical feed hopper 302, and the second bevel gear 311 on the rotating rod 309 rotates around the first bevel gear 306, so that when the rotating rod 309 makes a revolution, it also makes a rotation, so that the grinding balls 310 rotate while following the rotating rod 309 in revolution, grinding the silica powder falling into the annular grinding disc 301. The ground silica powder is on the annular grinding disc 301, and the silica powder meeting the particle size requirements falls into the discharge frame 319 through the filter holes 318. Since the discharge frame 319 is inclined, the silica powder smoothly discharges from the equipment under the action of gravity. During the whole process, the dust collector 7 continuously works to adsorb the dust generated during the grinding process, ensuring a clean working environment and the normal operation of the equipment.

[0035] In the crushing optimization adjustment stage, during the long-term crushing process, when the distance between the two crushing rollers 403 increases due to the wear of the crushing teeth 404, start the third servo motor 505, and its output end drives the bidirectional threaded rod 502 to rotate. Since the thread directions at both ends of the bidirectional threaded rod 502 are opposite, the two moving frames 504 will move relatively along the bidirectional threaded rod 502. The moving frames 504 are fixedly connected to the sliders 402, thereby driving the sliders 402 to move in the sliding grooves 401, so as to drive the two crushing rollers 403 to move relatively, and the distance between the two crushing rollers 403 can be adjusted.

[0036] In the ball milling gap adjustment stage, when the gap between the grinding balls 310 and the bottom wall of the annular grinding disc 301 increases due to wear, start the first servo motor 314, and its output end drives the unidirectional threaded rod 304 to rotate. Under the limitation of the fixed rod 305, the first bevel gear 306 moves downward along the unidirectional threaded rod 304, driving the rotating rod 309 and the grinding balls 310 to move downward through the rotating block 307 and the fixed block 308, so as to adjust the positions of the four grinding balls 310 at the same time, so that the four grinding balls 310 maintain a proper distance from the bottom wall of the annular grinding disc 301, ensuring the fineness of the silica powder grinding.

[0037] In the present invention, the wiring diagrams of the first servo motor 314, the second servo motor 316, the raw material conveyor 412, the third servo motor 505 and the dust collector 7 belong to the common general knowledge in the art. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the first servo motor 314, the second servo motor 316, the raw material conveyor 412, the third servo motor 505 and the dust collector 7 will not be explained in detail.
