Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological shaker technology, specifically a shaker with tilting and translation functions and adjustable tilt angle and translation distance. Background Technology
[0002] Biological shakers are a common laboratory instrument primarily used for bacterial culture, fermentation, hybridization, and biochemical reactions, as well as enzyme and cell tissue culture research. They are widely used in industries such as medicine, biology, molecular biology, pharmaceuticals, food, and the environment.
[0003] Oxygen transfer efficiency is a crucial parameter in biological culture, influenced by amplitude and rotation speed. Different biological cultures require different optimal amplitudes and rotation speeds. Furthermore, changes in amplitude and rotation speed can also cause changes in shear forces, making some shear-sensitive organisms more prone to death under high amplitude and high rotation speed conditions.
[0004] Currently, conventional shakers on the market can only achieve horizontal or tilting movements, and the cultivation environment they can provide is relatively limited.
[0005] Therefore, a shaking table with tilting and translation functions and adjustable tilting angle and translation distance is proposed to solve the above-mentioned problems. Utility Model Content

[0050] Working principle:
[0051] The translation guide rail 202 is mounted on the base plate 201. Two translation flexible bearing seats 203 are mounted on the slider of the translation guide rail 202. A translation flexible rotating shaft 204 is installed between the two translation flexible bearing seats 203. A rotary bearing seat 205 is mounted on the translation flexible rotating shaft 204. Two tilt bearing seats 208 are fixed at the bottom center of the rocker 1. A tilt rotating shaft 206 passes through the middle of the two tilt bearing seats 208. One end of the tilt rotating shaft 206 is fixed to the rotary bearing seat 205, and the other end is fixed to the auxiliary support roller 207. At this time, the rocker 1 can achieve horizontal reciprocating motion through the translation guide rail 202 and tilting reciprocating motion through the tilt bearing seats 208.
[0052] The mounting plate 301 is fixed to the base plate 201, and the reducer 302 is fixed to the mounting plate 301. The servo motor 303 drives the drive wheel 304 to rotate through the reducer 302. The drive shaft 308 is fixed to the mounting plate 301 through the drive shaft bearing seat 309, and the driven wheel 306 is installed at the end of the drive shaft 308. The drive wheel 304 drives the driven wheel 306 to rotate through the synchronous belt 305, and the driven wheel 306 drives the drive shaft 308 to rotate. The drive shaft 308 drives the motion adjustment block 310 to perform circular motion around the center of the drive shaft 308. The drive bearing seat 312 is installed at the front end of the rocker 1, and the motion adjustment block 310 passes through the bearing center of the drive bearing seat 312, driving the rocker 1 to move. The center of the rocker 1 can move horizontally, and the rocker 1 can rotate around the center of the rocker 1. The motion adjustment block 310 and the drive shaft 308 can be simplified into a crank mechanism. The front end of the shaker 1 can rotate around the center of the motion adjustment block 310; the simplified mechanism can be approximated as a crank-slider mechanism; the shaker 1 completes an approximate figure-eight trajectory under the drive shaft 308; the motion adjustment block 310 is fixed in different holes of the drive shaft 308, which is equivalent to modifying the length of the crank, so that the shaker 1 can complete different angles of tilt and different distances of horizontal displacement; because the motion adjustment block 310 is fixed in the drive shaft 308, it needs to occupy the space of three holes, so there are a total of 5 adjustable parameters; that is, the maximum tilt angle is 14° when the horizontal amplitude is ±86mm, the maximum tilt angle is 12.2° when the horizontal amplitude is ±75.5mm, the maximum tilt angle is 10.5° when the horizontal amplitude is ±64.8mm, the maximum tilt angle is 8.7° when the horizontal amplitude is ±54mm, and the maximum tilt angle is 7° when the horizontal amplitude is ±43.5mm.
