Description

Technical Field

[0001] This utility model relates to the field of biological shakers, and in particular to a sealed rocker mechanism suitable for high-temperature shakers. Background Technology

[0002] In cell culture, a shaker is typically used to inoculate microbial cells into a liquid culture medium and place them on the shaker for continuous shaking. Shaking ensures sufficient contact between the culture medium and oxygen, increasing the dissolved oxygen supply. Cells cultured with shaking exhibit uniform proliferation and high culture efficiency, making it widely used for strain screening and large-scale microbial culture. It is a common culture method in microbial physiology, biochemistry, fermentation, and other life science research fields. To meet the demand for high-temperature shakers designed to create a high-temperature environment for the growth of specific plant or animal cells or microorganisms, or for dry-heat sterilization shakers requiring high-temperature sterilization to prevent contamination of cultured strains, a high-temperature resistant, sealed shaking shaft mechanism has been developed.

[0003] Existing high-temperature shakers or dry heat sterilization shakers generally use the following methods: 1. The motor is isolated during the shaker design, and the eccentric shaft mechanism is placed inside the chamber. Due to the influence of bearings and belts, which are not resistant to high temperatures, this solution greatly affects the maximum temperature inside the chamber or the high-temperature dry heat sterilization time, resulting in poor performance or excessively high production and maintenance costs. 2. The entire shaking shaft mechanism is isolated, and a connecting rod and silicone telescopic sleeve are used for fixing to achieve high temperature resistance and sealing. Although this solution can isolate the shaking shaft mechanism from the high temperature and has a certain degree of airtightness, the connecting rod process affects the overall stability of the shaker and the load capacity of the shaker fixture plate. Furthermore, high temperature and eccentric movement can accelerate the aging of the silicone telescopic sleeve, releasing odors or causing damage, thus reducing the airtightness of the chamber.

The lower plate of the rocker shaft is provided with a driving eccentric shaft and a driven eccentric shaft. The working ends of both the driving and driven eccentric shafts are connected to the upper plate of the rocker shaft. The driving eccentric shaft is connected to the transmission rod two.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] This utility model provides a technical solution: a sealed rocker shaft mechanism suitable for high-temperature shaking tables, such as... Figures 1-3 As shown, it includes a lower rocker plate 1, an upper rocker plate 2 on the lower rocker plate 1, an eccentric mechanism 3 between the lower rocker plate 1 and the upper rocker plate 2, and a sealing transmission mechanism 4 on the upper rocker plate 2.

[0022] like Figure 1 , Figure 3 As shown, the eccentric mechanism 3 includes a motor 301, which is mounted on the lower plate 1 of the rocker shaft. The output end of the motor 301 is provided with a transmission rod 302, which drives the lower plate 1 of the rocker shaft. A transmission wheel 303 is provided on the transmission rod 302, and a transmission rod 304 is provided on one side of the transmission wheel 303. The transmission rod 304 is movably mounted on the lower plate 1 of the rocker shaft. A belt pulley 305 is provided on the transmission rod 304, and a belt 306 is fitted on the transmission wheel 303 and the belt pulley 305. The lower plate 1 of the rocker shaft is provided with an active eccentric shaft 307 and a driven eccentric shaft 308. The working ends of the active eccentric shaft 307 and the driven eccentric shaft 308 are both connected to the upper plate 2 of the rocker shaft. The active eccentric shaft 307 is connected to the transmission rod 304. The eccentric mechanism 3 is mounted as a whole on the outer box 5 of the high-temperature shaking table.

[0023] like Figure 1 , Figure 2 As shown, the sealing transmission mechanism 4 includes a transmission connecting rod 401. Several transmission connecting rods 401 are mounted on the upper plate 2 of the rocker shaft. The transmission connecting rods 401 are mounted on the eccentric mechanism 3, pass through the insulation mechanism 6 and the pre-reserved holes at the bottom of the inner box 7, and extend into the inner box 7. A sealing upper cover 402 is provided on the transmission connecting rod 401. A clamping plate 403 is provided on the top of the transmission connecting rod 401. The clamping plate 403 is fixed to the transmission connecting rod 401 by screws. A wave-shaped gasket 404 is provided between the sealing upper cover 402 and the clamping plate 403. A sealing plate 405 is provided below the sealing upper cover 402. The sealing plate 405 is provided with an installation structure corresponding to the sealing upper cover 402. The sealing plate 405 is tightly connected to the sealing upper cover 402 and is mounted on the transmission connecting rod 401. A sealing lower cover 406 is provided below the sealing plate 405.

[0024] like Figure 4 As shown, the sealing cover 402 is provided with a fixing groove 402-1.

[0025] like Figure 5 As shown, the sealing plate 405 is provided with a fixing boss 405-1.

[0026] In practical implementation, the eccentric mechanism 3 performs eccentric motion under the action of the active eccentric shaft 307 and the driven eccentric shaft 308. The motor 301 is started, driving the transmission rod 302 to rotate. The transmission rod 302 drives the transmission wheel 303 to rotate, which in turn drives the pulley 305 via the belt 306. The pulley 305 drives the transmission rod 304 to rotate, which in turn drives the active eccentric shaft 307 to rotate. Finally, the clamping plate 403 is driven by the connecting rod 401 to achieve the required eccentric motion of the shaking table. The lower sealing cover 406 is fixed to the bottom plate of the inner housing 7. The upper sealing cover 402 is fixed to the connecting rod 401 and can perform eccentric motion along with the connecting rod. The upper sealing cover 402 also has a fixing groove 402-1. A sealing plate 405 is installed between the upper sealing cover 402 and the lower sealing cover 406. The sealing plate 405 has a fixing boss 405-1 corresponding to the sealing upper cover 402. The clamping plate 403 is fixed to the transmission connecting rod 401 by screws. A corrugated gasket 404 is installed between the clamping plate 403 and the sealing upper cover 402. After the clamping plate 403 is fixedly installed, it compresses the corrugated gasket 404 to make the sealing plate 405 and the sealing lower cover 406 fit tightly together. Since the sealing plate 405 is made of high-temperature resistant and smooth materials such as graphite or PTFE, it can ensure that the sealing plate 405 slides on the sealing lower cover 406 under the drive of the transmission connecting rod 401. At the same time, the clamping force provided by the corrugated gasket 404 can ensure the airtightness of the inner box 7 while the sealing plate 405 slides. The eccentric mechanism 3 is installed on the outer casing 5, and the transmission connecting rod 401 is installed on the eccentric mechanism 3, passes through the insulation mechanism 6 and the reserved hole at the bottom of the inner casing 7, and extends into the inner casing 7.
