Abstract
Description
Technical Field
[0001] This utility model relates to a raw material grinding equipment for ceramic coating production, and in particular a high-efficiency ball mill for ceramic coating production. Background Technology
[0002] Ceramic coatings are a novel type of coating that allows organic and inorganic substances to react, thus combining the advantages of both. In the production process of ceramic coatings, to ensure more uniform integration of raw materials, a ball mill is used to grind large, lumpy raw materials, transforming them into powder for better integration with subsequent processing. Existing ball mills typically use a single vibration drive to rotate a grinding jar, limiting their grinding capacity to a single type of raw material. However, coating manufacturers produce a variety of products, each requiring the grinding of multiple raw materials. A single-material ball mill cannot adequately meet production demands, impacting overall production efficiency. Therefore, existing ball mills suffer from low efficiency when grinding multiple raw materials. Utility Model Content
[0003] The purpose of this invention is to provide a high-efficiency ball mill for ceramic coating production. This invention has the advantage of high working efficiency.
[0004] The technical solution of this utility model: a high-efficiency ball mill for ceramic coating production, comprising a shell and multiple grinding jars. Two symmetrically arranged support seats for horizontally fixing the grinding jars are provided on both sides of the shell. A linkage shaft is installed in the middle of the inner bottom surface of each support seat. A secondary bevel gear located inside the shell is installed at one end of each linkage shaft, and a fixing seat for connecting the grinding jars is provided at the other end, located inside the support seat. A first magnet is provided on the end face of the fixing seat away from the support seat. A fixing groove that mates with the fixing seat is provided on the end face of each grinding jar, and a second magnet that mates with the first magnet is provided on the inner bottom surface of the fixing groove. The outer casing contains two symmetrically arranged drive units, each equipped with a main bevel gear meshing with a secondary bevel gear. These two drive units rotate the support seats located on both sides of the frame, enabling simultaneous grinding of multiple grinding jars, improving work efficiency. They also allow operation when multiple grinding jars are not required simultaneously, ensuring flexibility. Furthermore, one drive unit can rotate two grinding jars, minimizing wear on the drive units while maintaining work efficiency, thus extending their service life.
[0005] In the aforementioned high-efficiency ball mill for producing ceramic coatings, the driving device includes a drive motor with a drive shaft mounted on it; the main bevel gear is mounted at the end of the drive shaft.
[0006] In the aforementioned high-efficiency ball mill for ceramic coating production, a lower fixing member with an arc shape and an upward opening is fixedly installed at the end of the support base, and an upper fixing member is rotatably installed on one side of the lower fixing member; a fixing seat is provided on the other side of the lower fixing member, and a pin is provided on the top surface of the fixing seat; a locking nut is rotatably installed at the end of the pin; the upper fixing member is also arc-shaped, and a pin seat that cooperates with the pin is provided on the side of the upper fixing member away from the connection with the lower fixing member; by using the lower fixing member and the upper fixing member, an openable auxiliary support device can be formed on the outside of the support base, ensuring that the ball mill jar can be installed more stably on the support base, thus ensuring the stability of operation.
[0007] In the aforementioned high-efficiency ball mill for producing ceramic coatings, the surface of the support base is provided with multiple uniformly distributed through holes; the through holes can accelerate the interaction between the internal environment of the support base and the external environment, and play a certain role in heat dissipation.
[0008] In the aforementioned high-efficiency ball mill for ceramic coating production, a base is provided inside the outer shell on one side of the two drive devices, and two fans are provided on the top surface of the base for cooling the drive devices; multiple evenly distributed heat dissipation holes are provided on both sides of the outer shell; the arrangement of the heat dissipation holes and fans can accelerate the flow between the internal environment and the external environment of the outer shell, improve the heat dissipation effect on the drive devices, and extend their service life.
[0009] Compared with existing technologies, this utility model improves upon existing ball mills by providing multiple support seats for mounting grinding jars on both sides of the outer shell, with each support seat equipped with a linkage shaft. Simultaneously, the linkage shafts at symmetrical positions on both sides are driven synchronously by the same drive device, enabling the simultaneous grinding of multiple grinding jars and improving work efficiency. Furthermore, by using two drive devices to rotate two linkage shafts at the same position, when grinding fewer grinding jars, only one drive device can be controlled for grinding, eliminating the need for a single drive device to rotate all linkage shafts. This reduces power consumption and also reduces the wear rate of the drive device due to excessive load, extending its service life and lowering production costs. Additionally, by providing a second magnet on the grinding jar, in conjunction with the first magnet on the linkage shaft's mounting base, the grinding jar is stably connected to the linkage shaft during grinding, ensuring operational stability.
[0010] Furthermore, this invention features a lower fixing member installed at the end of the support base, with an upper fixing member rotatably mounted on its top surface. A pin and a pin seat are provided between the upper and lower fixing members, forming an openable and closable fixing device. This allows the grinding jar to be further supported when mounted on the support base, ensuring operational stability. The pin and pin seat also ensure structural stability when the upper and lower fixing members are securing the grinding jar. Multiple evenly distributed through holes on the surface of the support base increase heat exchange between the grinding jar and the external environment, enhancing heat dissipation. A fan on the base, combined with ventilation holes on the side of the outer shell, accelerates airflow between the shell and the external environment, further improving heat dissipation for the internal drive motor and other components. Therefore, this invention not only improves work efficiency but also offers advantages such as long service life, high operational stability, low production cost, high structural stability, and excellent heat dissipation.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0018] Example. A high-efficiency ball mill for producing ceramic coatings includes a shell 1 and multiple grinding jars 2, configured as follows: Figures 1 to 5As shown, two symmetrically arranged support seats 3 for horizontally fixing the grinding jar 2 are provided on both sides of the outer shell 1. A linkage shaft 4 is installed in the middle of the bottom surface of each support seat 3. A secondary bevel gear 5 located inside the outer shell 1 is installed at one end of each linkage shaft 4, and a fixing seat 6 located inside the support seat 3 for connecting the grinding jar 2 is provided at the other end. A first magnet 7 is provided on the end face of the fixing seat 6 away from the support seat 3. A fixing groove 8 that cooperates with the fixing seat 6 is provided on the end face of the grinding jar 2. A second magnet 9 that cooperates with the first magnet 7 is provided on the bottom surface of the fixing groove 8. Two symmetrically arranged driving devices are provided inside the outer shell 1. A main bevel gear 10 that meshes with the secondary bevel gear 5 is provided on each driving device.
[0019] The driving device includes a drive motor 11, on which a drive shaft 12 is mounted; the main bevel gear 10 is mounted on the end of the drive shaft 12; a lower fixing member 13 with an arc shape and an upward opening is fixedly mounted on the end of the support base 3, and an upper fixing member 14 is rotatably mounted on one side of the lower fixing member 13; a fixing seat is provided on the other side of the lower fixing member 13, and a pin 15 is provided on the top surface of the fixing seat; a locking nut is rotatably mounted on the end of the pin 15; the upper fixing member 14 is also arc-shaped, and a pin seat 16 that cooperates with the pin 15 is provided on the side of the upper fixing member 14 away from the side connected to the lower fixing member 13; a plurality of evenly distributed through holes 17 are provided on the surface of the support base 3; a base 18 located on one side of the two driving devices is provided inside the outer shell 1, and two fans 19 for cooling the driving devices are provided on the top surface of the base 18; a plurality of evenly distributed heat dissipation holes 20 are provided on both sides of the outer shell 1.
[0020] Working principle: First, connect the entire device to an external safe mains power supply. Then, open the top cover of the grinding jar 2 and add the raw material to be ground into the grinding jar 2. Next, replace the top cover of the grinding jar 2 (which contains ball-shaped grinding elements for auxiliary grinding) to complete the loading process. Then, rotate the pin 15 to open the connection between the pin 15 and the pin seat 16. Next, flip the upper fixing member 14 upwards, causing it to move the pin seat 16 upwards and eventually separate from the pin 15. As the upper fixing member 14 continues to rotate, it flips to the side of the lower fixing member 13, causing the top of the lower fixing member 13 to... The surface is open; then the ball mill jar 2, which holds the raw materials, can be placed horizontally with its top cover facing the support base 3. The ball mill jar 2 is placed on the support base 3, and the second magnet 9 on the ball mill jar 2 and the first magnet 7 on the fixed base 6 cooperate with each other to make the ball mill jar 2 stably connected to the linkage shaft 4. Then the upper fixing part 14 is flipped back so that it is above the lower fixing part 13. Through the cooperation of the pin 15 and the pin seat 16, the lower fixing part 13 and the upper fixing part 14 can form a protective support cover on the outside of the ball mill jar 2, ensuring that the ball mill jar 2 can be stably installed on the support base 3 during the subsequent rotation and grinding process, thus ensuring the stability of the operation.
[0021] Next, the drive motor 11 is started (this control can be handled by an external controller or manually by pressing the start button; when using a controller, a programmable controller such as FX2C-20MRD, Cortex-R8, or Cortex-M7 can be used). After the drive motor 11 starts, it will drive the drive shaft 12 to rotate. After the drive shaft 12 rotates, it will drive the main bevel gear 10 to rotate. Because the main bevel gear 10 is meshed with the secondary bevel gear 5, when the main bevel gear 10 rotates, it will mesh with the secondary bevel gear 5, thereby causing the secondary bevel gear 5 to rotate. After the secondary bevel gear 5 rotates, it will drive the linkage shaft 4 to rotate. After the linkage shaft 4 rotates, it will drive the ball mill jar 2 to rotate through the fixed seat 6, so that the rotating ball mill jar 2 completes the grinding work of the raw material.
[0022] After the grinding work is completed, the drive motor 11 is stopped, causing the grinding jar 2 and the linkage shaft 4 to stop rotating. Then, the pin 15 and the pin seat 16 are changed from the locked state to the unlocked state. Then, the upper fixing part 14 is flipped outward to separate the upper fixing part 14 from the lower fixing part 13. Finally, the grinding jar 2 is pulled outward to separate the grinding jar 2 from the support seat 3, completing the unloading work. During the entire grinding process, the through hole 17 on the support seat 3 can increase the heat transfer between the grinding jar 2 and the support seat 3 to the external environment, improving the heat dissipation effect. At the same time, the fan 19 is started. After the fan 19 is started, it blows the heat inside the outer shell 1 towards the heat dissipation hole 20, thereby increasing the air flow speed between the internal environment of the outer shell 1 and the external environment, thus completing the heat dissipation work of the drive motor 11 and improving the overall heat dissipation effect.
