[0002] In the laboratory, it is necessary to mix two or more powder materials, liquid solvents, and / or resin materials. During the mixing process, experiments need to be conducted on different proportions and combinations of powder materials. Different proportions and combinations of powder materials need to be placed in different shaking flasks. However, in the existing shaking chamber technology, only one shaking flask of powder materials, liquid solvents, and / or resin materials can be mixed at a time. Multiple shaking flasks require multiple openings of the shaking chamber for mixing, which results in a significant amount of time spent mixing powder materials, liquid solvents, and / or resin materials, leading to low overall experimental efficiency.

Detailed Implementation
[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] See Figures 1-3 This utility model provides a technical solution:
[0023] A laboratory-grade high-speed mixing shaker includes a housing 1, a door 2, a vibration frame 3, a vibration drive 4, a base plate 5, a pressure plate 6, a pressure head 7, a pressure regulating assembly, and a transmission assembly. The transmission assembly is located inside the housing 1, and its input end is connected to the output end of the vibration drive 4. The vibration drive 4 is fixedly installed inside the housing 1. The upper end of the vibration frame 3 is located on the output end of the transmission assembly. The base plate 5 is fixedly installed on the lower end of the vibration frame 3. The pressure plate 6 is located in the middle of the vibration frame 3, and it is parallel to the base plate 5. Multiple shaking bottles 8 are placed on the base plate 5. The upper end of each shaking bottle 8 mates with the lower end of a pressure head 7. A pressure chamber 9 is provided inside the pressure plate 6, and a limiting sliding hole 10 is provided on the pressure chamber 9. The upper end of the pressure head 7 is sealed and slidably installed in the limiting sliding hole 10. The pressure chamber 9 is connected to the pressure regulating assembly. The door 2 is located on one side of the housing 1. A second sealing ring is provided between the outer wall of the pressure head 7 and the inner wall of the limiting sliding hole 10. The enclosure 1 houses the door 2, vibration frame 3, vibration drive component 4, pressure regulating component, and transmission component. The door 2 on the enclosure 1 ensures user safety. The vibration drive component 4 is a motor, a common technology, which drives the transmission component. The transmission component then drives the vibration frame 3 to vibrate. The pressure plate 6 on the vibration frame 3 mounts the pressure head 7. The pressure head 7 works in conjunction with the base plate 5 to fix the shaking bottle 8. Each pressure head 7 can hold one shaking bottle 8, allowing multiple shaking bottles 8 to be fixed and processed simultaneously. The pressure regulating component drives the pressure head 7, which, in conjunction with the base plate 5, fixes the shaking bottle 8. The shaking bottle 8 contains powder materials that need to be thoroughly mixed. The multiple pressure heads 7 on the pressure plate 6 are arranged in a matrix.
[0024] In some embodiments, the transmission assembly includes a transmission rod 11, a fixed shaft 12, a connecting block 13, and a bearing seat 14. The bearing seat 14 is fixedly disposed inside the housing 1. The fixed shaft 12 is rotatably disposed on the bearing seat 14. One end of the fixed shaft 12 is connected to the vibration drive 4, and the other end of the fixed shaft 12 is fixedly connected to one end of the connecting block 13. The other end of the connecting block 13 is fixedly connected to the transmission rod 11. The axis of the fixed shaft 12 is parallel to the axis of the transmission rod 11 but not coaxial. The vibration frame 3 is rotatably disposed on the transmission rod 11. Connecting blocks 13 are symmetrically disposed at both ends of the transmission rod 11. The two connecting blocks 13 are respectively connected to the two fixed shafts 12. The two fixed shafts 12 are respectively disposed on the two bearing seats 14 and are coaxial. In this system, the vibration drive 4 drives one of the fixed shafts 12 to rotate via a belt assembly, which in turn drives the transmission rod 11 to rotate. Through the coordinated use of the transmission rod 11, the fixed shaft 12, the connecting block 13, and the bearing seat 14, the vibration frame 3 can not only vibrate up and down on the transmission rod 11 but also swing left and right, thus ensuring thorough mixing of the powder material in the shaking bottle 8. The two fixed shafts 12 are mounted on two bearing seats 14 via bearings, and the two bearing seats 14 are fixed inside the housing 1. In the actual high-speed vibration chamber, the bearing seats 14 are fixed inside the housing 1 by a shock-absorbing device, which is also present in the prior art.
[0025] In some embodiments, a stabilizing plate 15 is fixedly installed inside the housing 1. The stabilizing plate 15 has stabilizing holes that cooperate with the vibration frame 3. The stabilizing plate 15 has two functions: first, to prevent the vibration frame 3 from rotating around the transmission rod 11; and second, to allow the vibration frame 3 to have a larger left-right swing space under the action of the stabilizing holes.
[0026] In some embodiments, a buffer pad 16 that mates with the shaker bottle 8 is provided on the base plate 5, and an elastic pad 17 that mates with the shaker bottle 8 is provided on the end of the pressure head 7. Both the buffer pad 16 and the elastic pad 17 are existing elastic rubber pads. The buffer pad 16 is fixed to the base plate 5, and the elastic pad 17 is fixed to the pressure head 7. The cooperation of the buffer pad 16 and the elastic pad 17 prevents the shaker bottle 8 from being crushed.
[0027] In some embodiments, the pressure regulating assembly includes a pressure tube 18, a regulating tube 19, a regulating rod 20, and a regulating drive 21. One end of the pressure tube 18 is sealed and connected to the pressure chamber 9, and the other end of the pressure tube 18 is sealed and connected to one end of the regulating tube 19. One end of the regulating rod 20 is slidably disposed within the other end of the regulating tube 19, and the other end of the regulating rod 20 is connected to the output portion of the regulating drive 21. The regulating drive 21 is fixedly disposed within the housing 1. A first sealing ring is provided between the inner wall of the regulating tube 19 and the outer wall of the regulating rod 20. The adjusting drive component 21 is an electric push rod, hydraulic cylinder, or pneumatic cylinder in the prior art. The adjusting drive component 21 drives the adjusting rod 20 to move. The adjusting rod 20 pushes the hydraulic oil in the adjusting tube 19 into the pressure chamber 9 through the pressure tube 18 or draws the hydraulic oil in the pressure chamber 9 into the adjusting tube 19 through the pressure tube 18. The hydraulic oil in the pressure chamber 9 drives the pressure head 7 to move, thereby realizing the fixing or loosening of the shaking bottle 8. Since multiple pressure heads 7 are cooperated with by pressure chambers 9, the force on each pressure head 7 is the same.
