Description

Technical Field

[0001] This utility model relates to the field of planetary ball mill technology, and in particular to an automatic fastening planetary ball mill. Background Technology

[0002] Currently, there are many types of planetary ball mills on the market, and the grinding jars are generally tightened manually using locking handles. The locking handles rely on a screw and nut for fixing. Since the height of the grinding jar varies depending on its size, the extension length of the screw needs to be manually adjusted. This means that users must manually tighten and loosen the jars each time they make a sample. To ensure the grinding jars do not rotate within the equipment, users with less strength may need to use a special wrench for tightening and loosening, which is very time-consuming.

[0003] Currently, most planetary ball mills on the market have structures such as Figure 9 As shown, it mainly includes: ball mill support body 100, large V-belt pulley 200, grinding station 440, and a counterweight 500; there are other structural forms, but the principle is not much different. By replacing the counterweight with a grinding jar, a two-station grinding mill is obtained; by enlarging the size of the turntable and increasing the number of synchronous pulleys, a four-station grinding mill is obtained.

[0004] The grinding station 440 is fixed to the synchronous pulley inside the equipment, allowing the grinding station 440 to rotate together with the synchronous pulley. The grinding jar 300 is fixed to the grinding station 440 by the locking handle 400. The user holds the limiting ring 410 with one hand and rotates the knob 430 with the other hand to move the lead screw 412 downward to the grinding jar 300. At this time, continue to rotate the knob 430, and the bracket 411 of the locking handle will contact the baffle 420 on the turntable until it is tightened (until it cannot be rotated by hand). Release the limiting ring 410, and the grinding jar is locked. In order to achieve the purpose of stable grinding, it is also necessary to adjust the distance of the counterweight 500 according to the weight of the grinding jar. Otherwise, it is easy to generate vibration, which will prevent the experiment from operating normally or even damage the equipment. Utility Model Content
