Description

Technical Field

[0001] This utility model relates to the field of ball milling equipment technology, specifically a ball milling equipment for metal powder processing. Background Technology

[0002] Ball milling devices are widely used in processes such as material crushing, mixing, grinding, and mechanical alloying, especially in mining, metallurgy, chemical engineering, ceramics, building materials, and laboratory research. In the processing of metal powders, ball milling is achieved by impacting the metal raw materials with grinding balls inside the device. However, in existing ball milling technologies, the metal is impacted and produces powder, which accumulates and can affect the impact effect, leading to reduced processing efficiency. Furthermore, the powder can scatter during the ball milling process, resulting in material waste. Therefore, improvements to existing technologies are needed. Utility Model Content

[0003] The purpose of this invention is to provide a ball milling device for metal powder processing, which solves the problems of low ball milling efficiency and powder scattering during processing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a ball milling cover, a ball milling cylinder, and a screw to the base. During use, the raw materials and grinding balls can be put into the inside of the ball milling cylinder. Then, the raw materials are ball milled by the rotation of the ball milling cylinder.

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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 A ball milling device for metal powder processing includes a base 1. Two symmetrically distributed connecting frames 2 are hinged to the upper end of the base 1. A ball milling cover 3 is fixedly connected between the two connecting frames 2. A ball milling cylinder 6 is installed inside the ball milling cover 3 through bearings. A sealing cover 4 is hinged to the left end of the ball milling cover 3. A limit mechanism 5 is provided on the ball milling cover 3. A discharge cover 7 is fixedly connected to the lower end of the ball milling cover 3. A flip plate 9 is hinged to the upper right part of the base 1. A screw 10 is installed inside the flip plate 9 through bearings. A linkage frame 11 is hinged to the right end of the ball milling cover 3. An internally threaded tube 12 is fixedly connected inside the linkage frame 11. A motor 13 is fixedly installed at the lower end of the flip plate 9.

[0020] Please see Figure 1 , Figure 2 , Figure 3 Motor 18 is fixedly installed on the right end of the ball mill cover 3. The output shaft of motor 18 is fixedly connected to the connecting shaft of the ball mill cylinder 6. Motor 18 can drive the ball mill cylinder 6 to rotate. The output shaft of motor 213 is fixedly connected to screw 10. Screw 10 is connected to internal threaded tube 12 by thread. Screw 10 can drive the linkage frame 11 to move through the threaded engagement between screw 10 and internal threaded tube 12.

[0021] Please see Figure 1 , Figure 3 , Figure 4 The limiting mechanism 5 includes a fixing pin 51. The fixing pin 51 is fixedly connected to the upper left part of the ball mill cover 3. The limiting frame 52 is slidably connected to the outside of the fixing pin 51. A spring 53 is provided on the outside of the fixing pin 51. The fixing pin 51 can guide the movement of the limiting frame 52. One end of the spring 53 is fixedly connected to the fixing pin 51, and the other end of the spring 53 is fixedly connected to the limiting frame 52. The spring 53 can drive the limiting frame 52 to automatically reset through elastic force. The limiting frame 52 slides in contact with the sealing cover 4 and the ball mill cover 3.

[0022] The specific implementation process of this utility model is as follows: When in use, the raw material and grinding balls are placed inside the ball mill cylinder 6, and then the sealing cover 4 is flipped upward. At the same time, the limiting frame 52 is pushed upward. The limiting frame 52 compresses the spring 53. When the sealing cover 4 is flipped vertically, the limiting frame 52 is released and the spring 53 returns to its original position. The spring 53 can drive the limiting frame 52 to slide to the outside of the sealing cover 4 through its elastic force, thus limiting the sealing cover 4. Then, the motor 8 is started. The motor 8 drives the ball mill cylinder 6 to rotate. During the rotation of the ball mill cylinder 6, the raw material can be ground by the grinding balls. During the process, the powder generated by grinding can be filtered by the ball mill cover 3 and discharged through the discharge cover 7, thereby effectively improving the ball milling efficiency. In addition, the ball mill cover 3 can be sealed by the sealing cover 4 during the ball milling process.

[0023] Simultaneously, during the ball milling process, motor 2 13 is started, which drives screw 10 to rotate. During the rotation of screw 10, it can drive the ball milling shroud 3 to deflect, thereby increasing the turbulence of the ball milling process and further improving the ball milling efficiency.
