Description

Technical Field

[0001] This utility model relates to the field of raw material adding machine technology, specifically an auxiliary device for adding raw materials to culture media. Background Technology

[0002] In microbial culture, biological experiments, and related biological work, the preparation of culture media is a crucial step, and the precise addition and uniform mixing of culture media raw materials directly affect the growth status of cultures and the accuracy of experimental results. Among these, liquid raw materials, as an important component of culture media, have always been a focus of attention in the industry due to the stability of their addition process and the mixing effect.

[0003] Currently, existing auxiliary devices for adding culture medium raw materials generally adopt a "static receiving" mode when handling liquid raw material addition. That is, the storage tube is fixed at the bottom of the injection tube and passively waits for the injection tube to deliver liquid raw materials. Under this structural design, the storage tube remains stationary throughout the entire addition process. Since some liquid raw materials have solute precipitation characteristics, or different liquid raw materials are prone to stratification in the early stage of mixing, the stationary storage tube cannot achieve autonomous and uniform mixing of the internal liquid. To solve this problem, the existing operation often relies on manually shaking the storage tube to promote mixing. However, manual shaking not only increases the labor intensity of operators, but also makes it difficult to maintain consistency, which can easily lead to large differences in the mixing effect of different batches of raw materials, affecting the uniformity of the culture medium composition.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] An auxiliary device for adding culture medium raw materials includes a housing 1, on which multiple sets of switch buttons 11 are provided. A base 6 is fixedly installed at the bottom of the housing 1, and a mounting groove 91 is provided on the base 6. Multiple sets of linkage gears 81 and multiple sets of support gears 83 are rotatably installed in the mounting groove 91. Each set of support gears 83 has a support ring plate 22 fixedly connected to its top. A fixing plate 9 is fixedly installed inside the housing 1, and a motor 8 is fixedly installed on the fixing plate 9. A drive gear 82 is fixedly installed on the output shaft of the motor 8, and the drive gear 82 meshes with a set of linkage gears 81. The motor 8 drives the drive gear 82. The transmission of the linkage gear 81 and the support gear 83 drives the support ring plate 22 to rotate, thereby causing the liquid storage tube to rotate. This achieves automatic mixing of the liquid in the liquid storage tube without the need for manual shaking. This not only reduces the labor intensity of the operators but also avoids the problem of uneven mixing caused by manual operation, ensuring the consistency of the liquid mixing effect. The outer shell 1 is equipped with a liquid delivery mechanism for adding liquid raw materials. A positioning plate 2 is fixedly installed on one side of the outer shell 1, and multiple sets of limiting rings 21 are rotatably installed on the positioning plate 2 via bearings. Limiting components 3 are set in the multiple sets of limiting rings 21 and the multiple sets of support ring plates 22 for clamping the liquid storage tube.

[0024] Please see Figure 2 The infusion mechanism includes multiple sets of liquid storage tanks 42 fixedly installed inside the outer casing 1. Each set of liquid storage tanks 42 is equipped with an infusion pump 52, and the ends of each set of infusion pumps 52 are connected to guide tubes 51. The ends of each set of guide tubes 51 are connected to injection tubes 5, and the injection tubes 5 are located above multiple sets of limiting rings 21. The infusion pumps 52 can accurately control the delivery volume of liquid raw materials. Compared with manual addition, it greatly improves the accuracy of raw material addition, ensures the accurate proportion of each component in the culture medium, and helps to ensure the culture effect. The guide tubes 51 guide the raw materials delivered by the infusion pumps 52 to the injection tubes 5. The injection tubes 5 are located above the limiting rings 21, which can accurately inject the raw materials into the storage tubes and reduce the splashing and waste of raw materials.

[0025] Please see Figure 1 and Figure 2 The top of each of the multiple infusion pumps 52 is connected to a connecting pipe 41, and the top of the connecting pipe 41 is fitted with an annular cover 4 by a threaded rotation. When not replenishing raw materials, the annular cover 41 can seal the storage tank 42 to prevent external dust and impurities from entering the storage tank 42 and contaminating the raw materials. At the same time, it can also prevent the volatilization of volatile raw materials in the storage tank 42, thus ensuring the purity and quality of the raw materials.

[0026] Please see Figure 4Multiple sets of limiting rings 21 and support ring plates 22 have multiple sets of grooves 31 on their inner walls. The limiting component 3 includes a sleeve 34 fixedly installed in the multiple sets of grooves 31, and a spring 33 is fixedly installed on the inner wall of the sleeve 34. A telescopic rod 32 is fixedly connected to the end of the spring 33, and a clamping block 35 is fixedly connected to the end of the telescopic rod 32. The elasticity of the spring 33 allows the telescopic rod 32 to extend and retract flexibly, driving the clamping block 35 to adapt to liquid storage pipes of different diameters, thus improving the versatility of the device. The clamping block 35 directly contacts the liquid storage pipe, achieving clamping and fixing of the liquid storage pipe.

[0027] Please see Figure 4 The outer surface of the clamping block 35 is covered with rubber. When clamping the liquid storage tube, the rubber can prevent hard contact between the clamping block 35 and the liquid storage tube, thus preventing the liquid storage tube from being scratched.

[0028] Please see Figure 1 A maintenance plate 7 is fixedly installed on one side of the outer casing 1 by bolts, and multiple sets of heat dissipation grooves 71 are opened on the outer surface of the maintenance plate 7. When the internal components of the device malfunction, the operator can easily remove the bolts to open the maintenance plate 7 and inspect and maintain the internal components, which reduces the difficulty of maintenance and saves maintenance time. The multiple sets of heat dissipation grooves 71 on the outer surface of the maintenance plate 7 can dissipate the heat generated by the motor 8 when the device is running in a timely manner, avoiding the components from being affected by excessive temperature and affecting their performance and service life, thus ensuring the stable operation of the device.

[0029] Working principle: First, the liquid storage tube is positioned and fixed. The liquid storage tube to be received is inserted from the top of the limiting ring 21 on the positioning plate 2, so that the bottom of the liquid storage tube is placed stably in the support ring plate 22 of the base 6. During this process, the limiting ring 21 and the limiting component 3 on the inner wall of the support ring plate 22 will automatically adapt to the diameter of the liquid storage tube. The spring 33 in the groove 31 pushes the telescopic rod 32 out of the sleeve 34 through its own elasticity, which drives the clamping block 35 to tightly fit the outer wall of the liquid storage tube. Since the rubber layer wrapped on the outer surface of the clamping block 35 has anti-slip properties, it can not only prevent the liquid storage tube from sliding due to subsequent rotation, but also prevent hard contact from scratching the tube wall. Finally, the liquid storage tube is stably fixed in the vertical direction and can be adapted to liquid storage tubes of different specifications.

[0030] Next, the operator sets the type and dosage of the raw material to be added using the switch button 11 on the outer casing 1. Upon receiving the instruction, the infusion pump 52 of the corresponding storage tank 42 starts. The infusion pump 52 draws a quantitative amount of liquid raw material from the storage tank 42 and delivers it to the injection pipe 5 through the guide pipe 51. Then, the injection pipe 5 accurately injects the liquid into the corresponding storage pipe below. During the injection process, the injection pipe 5 is located directly above the limiting ring 21, which can ensure that the liquid raw material falls vertically into the storage pipe and avoids splashing. If the raw material in the storage tank 42 is insufficient, the annular cap 4 at the top of the connecting pipe 41 can be unscrewed, and the raw material can be added to the storage tank 42 through the connecting pipe 41. After the replenishment is completed, the annular cap 4 is tightened again to ensure the sealing of the storage tank 42.

[0031] Finally, the raw materials are automatically mixed. During or after the liquid injection, the motor 8 can be started by the switch button 11. The output shaft of the motor 8 drives the drive gear 82 to rotate. The drive gear 82 meshes with a set of linkage gears 81. Through the sequential meshing of adjacent linkage gears 81, the power is transmitted to the edge linkage gear 81, which in turn drives the support gear 83 meshing with it to rotate in the mounting groove 91. The support ring plate 22 at the top of the support gear 83 rotates together. Since the liquid storage tube is fixed between the support ring plate 22 and the limiting ring 21 by the clamping block 35, the liquid storage tube will rotate synchronously with the support ring plate 22. The limiting ring 21 rotates with the liquid storage tube to achieve driven engagement. The rotation of the liquid storage tube causes the internal liquid raw materials to produce a centrifugal stirring effect, effectively avoiding solute precipitation or liquid stratification, and achieving automatic uniform mixing instead of manual shaking.
