[0002] In the field of laboratory micro-coating preparation, vibratory milling is a key process that plays a decisive role in the quality of the finished coating. However, traditional vibratory milling equipment has several shortcomings in practical applications:

[0003] On the one hand, the sample fixing methods are relatively rudimentary, often using simple clips or straps to secure the sample container. For trace amounts of coating raw materials, this is insufficient to provide a precise and stable fixation. During the grinding process, sample spillage and shaking of the sample container are common, leading not only to material waste but also to experimental errors, affecting the accuracy of the coating component ratios and ultimately reducing the quality of the finished coating product.

[0004] On the other hand, traditional equipment has poor grinding efficiency and uniformity. Some equipment uses a single rotation or linear vibration method, which cannot ensure that trace amounts of coating raw materials are fully impacted and rubbed, resulting in uneven mixing of the coating components.

A clamping nut 56 is threaded to the outside of the stud 54. The clamping nut 56 is located at the top of the upper connecting block 5 and is in close contact with its top.

[0026] The top of the sample preparation tube 6 is provided with a tube plug 521, which is fixed to the upper sample tube clamp 52. The bottom of the sample preparation tube 6 is provided with a groove 531, which is opened in the lower sample tube clamp 53.

[0027] The drive assembly includes a through slot 32 inside the swing arm 3. A connecting rod 33 is hinged inside the through slot 32. The connecting rod 33 is vertically positioned below the swing arm 3. An eccentric wheel 41 is hinged to one end of the bottom of the connecting rod 33. A drive motor 4 is provided at one end of the eccentric wheel 41. The drive motor 4 is mounted on the top of the base 1, and the shaft of the drive motor 4 is connected to the middle position of the eccentric wheel 41.

[0028] Link 33 is located on one side of the end of eccentric disk 41, and the side of the end of eccentric disk 41 away from the center is hinged to the bottom of link 33.

[0029] Working principle:

[0030] During vibratory grinding, the raw material to be processed is first placed into the sample preparation tube 6. As the core component carrying the raw material, the sample preparation tube 6 is fixed as follows: It is placed stably between the tube plug 521 and the groove 531, ensuring the bottom of the sample preparation tube 6 is fully embedded in the groove 531. This groove 531 is designed to provide stable bottom support for the sample preparation tube 6, ensuring the safety and stability of subsequent operations. Then, by rotating the clamping nut 56, the upper connecting block 5 moves downwards, gradually approaching the lower connecting block 51. During this process, the distance between the upper sample clamp 52 and the lower sample clamp 53 gradually decreases, while the tube plug 521 slowly moves into the opening at the top of the sample preparation tube 6. When the tube plug 521 is fully embedded in the opening at the top of the sample preparation tube 6, the rotation of the clamping nut 56 should be stopped immediately. At this point, the upper sample clamp 52, the lower sample clamp 53, the groove 531, and the tube plug 521 form a complete and stable clamping system, firmly fixing the sample preparation tube 6 and preventing it from shaking or shifting during grinding.

[0031] After the sample tube 6 is fixed in place, the drive motor 4 can be started. As the power source for the entire vibratory grinding equipment, the drive motor 4 drives the eccentric wheel 41 to rotate synchronously. The unique eccentric structure of the eccentric wheel 41 allows it to generate periodic up-and-down forces during rotation. Specifically, the rotating eccentric wheel 41 first pulls the connecting rod 33 downwards, then pushes it upwards, repeating this cycle to continuously provide a stable driving force for the swing arm 3. Since one end of the swing arm 3 is hinged to the support 2 via the hinge seat 31, this hinge structure gives the swing arm 3 the ability to rotate flexibly. Under the continuous downward pull and upward push of the connecting rod 33, the swing arm 3 rotates up and down around the connecting shaft connected to the hinge seat 31. Simultaneously, the clamping assembly installed at the other end of the swing arm 3 also swings up and down rhythmically, causing the sample tube 6 clamped thereon to swing up and down as well. During this high-frequency reciprocating vibration process, the raw material inside the sample preparation tube 6 is continuously subjected to impact and friction, achieving a highly efficient vibration grinding effect. It is important to note that during equipment operation, operators must closely monitor the equipment's operating status. If abnormal vibration or noise is detected, the machine should be stopped immediately for inspection to ensure safe and stable operation.
