Abstract
Description

[0002] The double planetary ball mill is a common equipment for mixing, fine grinding and small batch production of high-tech materials in the laboratory. It uses two planetary operations. When the turntable rotates (revolution), it drives the ball mill to rotate around the axis of rotation, and the direction is opposite to the rotation of the turntable. When the balls in the ball mill move together with the ball mill, they are affected by the superposition of Coriolis force (i.e., rotational deflection force), generating strong impact force and friction force. This combination of impact and friction enables the grinding balls in the jar to quickly fine grind the materials, mix and disperse the samples in high-speed motion. When the existing double planetary ball mill is used, the ball mill of a specific specification is generally fixed by the corresponding fixing sleeve, which has low versatility and cannot adapt to most ball mills of specifications.

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0020] Example: Reference Figure 1-3A double planetary ball mill comprises a housing 1, a motor 2 is mounted on one side of the housing 1, a ball mill assembly 3 is mounted on the other side, the output end of the motor 2 is connected to a first transmission assembly 4, and the first transmission assembly 4 is connected to the ball mill assembly 3 through a second transmission assembly 5.

The first transmission assembly 4 includes a rotating shaft 24, a first synchronous wheel 25 and a second synchronous wheel 26. The rotating shaft 24 is connected to the output end of the motor 2. The first synchronous wheel 25 is installed on the rotating shaft 24. The first synchronous wheel 25 and the second synchronous wheel 26 are connected by a synchronous belt 27. The second synchronous wheel 26 is connected to the fixed gear center shaft 20. During operation, the motor 2 starts to drive the rotating shaft 24 to rotate. The rotating shaft 24 rotates through the first synchronous wheel 25 and drives the second synchronous wheel 26 to rotate under the action of the synchronous belt 27, thereby driving the central axis of the fixed gear 19 to rotate; the central axis 20 of the fixed gear rotates the working turntable 18 and the fixed gear 19. Since the fixed gear 19 is meshed with the transition gear 22, the fixed gear 19 rotates and drives the transition gear 22 to rotate in the opposite direction. At the same time, since the transition gear 22 is meshed with the planetary gear 21, the transition gear 22 rotates and drives the planetary gear 21 to rotate in the opposite direction, thereby driving the ball mill assembly 3 to rotate in the opposite direction to the working turntable 18. That is, when the central axis 20 of the fixed gear drives the working turntable 18 to revolve, it drives the ball mill 7 to rotate around the planetary axis 23, and the direction of rotation is the same as that of the turntable, forming a planetary motion.
[0021] The ball mill assembly 3 includes a fixed sleeve 6, a ball mill 7, a top fixing part 8 and at least two side fixing parts 9. The ball mill 7 is placed in the fixed sleeve 6. An insulation board 30 is installed between the fixed sleeve 6 and the ball mill 7 to prevent the fixed sleeve 6 from generating a large amount of heat when the ball mill 7 rotates, which is then conducted into the ball mill 7 and causes adverse effects on the materials. A fixed threaded hole 28 is provided at the bottom of the fixed sleeve 6, and a threaded column 29 is connected to the bottom of the ball mill 7. The ball mill 7 and the fixed sleeve 6 are threadedly connected to the fixed threaded hole 28 through the threaded column 29 for preliminary fixation, and also to ensure that the position of the ball mill 7 will not shift when it rotates. At least two threaded holes are provided on the fixing sleeve 6, and the side fixing member 9 includes a threaded rod 10 and a side fixing pressure block 11, the threaded rod 10 is threadedly connected to the threaded hole, one end of the threaded rod 10 passes through the threaded hole and is connected to the side fixing pressure block 11, and the other end of the threaded rod 10 is threadedly connected to a fixing seat 12, and through the threaded connection between the threaded rod 10 and the threaded hole on the fixing sleeve 6, the rotating threaded rod 10 drives the side fixing pressure block 11 to move directly to the ball mill 7, and then further locks it through the fixing seat 12 to complete the horizontal fixation of the ball mill 7; through the adjustment of the threaded rod 10, the ball mill 7 of most specifications can be fixed, and the versatility is high. Fixed grooves 13 are respectively provided on both sides of the upper part of the fixing sleeve 6, and the top fixing part 8 includes a ram screw 14, a fixed beam 15 and a top fixed pressure block 16. The ram screw 14 passes through the fixed beam 15 and is connected to the top fixed pressure block 16; limit blocks are respectively installed on both sides of the fixed beam 15, and the fixed beam 15 is an elastic beam. The two ends of the fixed beam 15 pass through the fixed groove 13 respectively, and the limit blocks are used for limiting to prevent the fixed beam 15 from sliding out of the fixed groove 13 during the fixing process; the ram screw 14 is threadedly connected with a cap 17, and through the threaded connection between the ram screw 14 and the fixed beam 15, the rotating ram screw 14 drives the top fixed pressure block 16 to move directly to the top of the ball mill 7, and then further locked by the cap 17 to complete the vertical fixation of the ball mill 7.
[0022] The working principle of the utility model is as follows: after the ball mill 7 is placed on the fixed sleeve 6, the ball mill 7 and the fixed sleeve 6 are threadedly connected through the threaded column 29 and the fixed threaded hole 28 for preliminary fixation; then, the two ends of the fixed crossbeam 15 pass through the fixed groove 13 respectively, and under the threaded connection between the horn screw 14 and the fixed crossbeam 15, the top fixed pressing block 16 is driven to move directly to the top of the ball mill 7 by rotating the horn screw 14, and then further locked by the cap 17 to complete the vertical fixation of the ball mill 7; then the side fixing piece 9 fixes the ball mill 7 in the horizontal direction; and then, through the threaded connection between the threaded rod 10 and the threaded hole on the fixed sleeve 6, the threaded rod 10 is rotated to drive the side fixed pressing block 11 to move directly to the ball mill 7, and then further locked by the fixed seat 12 The motor 2 is locked to fix the ball mill 7 in the horizontal direction; when working, the motor 2 is started to drive the rotating shaft 24 to rotate, and the rotating shaft 24 rotates through the first synchronous wheel 25 under the action of the synchronous belt 27 to drive the second synchronous wheel 26 to rotate, thereby driving the fixed gear center shaft 20 to rotate; the fixed gear center shaft 20 drives the rotating working turntable 18 and the fixed gear 19 to rotate. Since the fixed gear 19 is meshed with the transition gear 22, the fixed gear 19 rotates to drive the transition gear 22 to rotate in the opposite direction. At the same time, since the transition gear 22 is meshed with the planetary gear 21, the transition gear 22 rotates to drive the planetary gear 21 to rotate in the opposite direction, thereby driving the ball mill assembly 3 to rotate in the same direction as the working turntable 18, so as to finely grind, mix and disperse the materials in the ball mill 7.
