Description

Technical Field

[0001] The present invention relates to a variable load module and a multi-degree-of-freedom rotating vortex instrument for complex mixing of reagents, which relates to a variable load module installed on a multi-degree-of-freedom rotating vortex instrument for complex mixing of reagents and for mixing batches of reagents. The invention belongs to the technical field of oscillation instruments, and particularly relates to a variable load module that can quickly and firmly install a disassembly component on a support component through a snap-on component to meet the requirements of different reagent mixing quantities. Background Art

[0002] In scientific research experiments and industrial production processes, fully mixing reagents is an extremely critical link. The effective mixing of reagents is directly related to the accuracy of experimental results, the stability of product quality and the level of production efficiency. At present, common reagent mixing technologies mainly rely on traditional vortex instruments. Traditional vortex instruments mostly use a motor-driven eccentric wheel or directly connect an oscillating component to make the container containing the reagent produce eccentric rotational oscillation or vortex oscillation. However, they have obvious defects. First, the motion mode is single and can only provide a simple oscillation effect, which is prone to uneven mixing or stratification. Especially for viscous liquids, multi-layer solutions or reagents containing particles, it is difficult to achieve gentle and comprehensive uniform mixing. Violent vortex oscillations are prone to shear force and bubbles, which damage sensitive samples such as cell reagents or protein reagents, affecting the reliability of experimental results. Second, it is difficult to achieve precise adaptation for reagents of different viscosities and densities. When facing high-viscosity reagents, the mixing effect of traditional vortex instruments is greatly reduced, and the reagents cannot be fully mixed. For low-viscosity reagents, excessive oscillation may cause the reagents to splash, resulting in experimental errors and waste of resources.

[0003] Publication number CN219861376U discloses a uniform stirring device for NK cell reagents, including a base, a vertical plate fixed on the top of the base, a first motor fixedly connected to the inner wall of the vertical plate, an output shaft of the first motor fixedly connected to a screw, the other end of the screw is rotatably connected to the inner wall of the vertical plate, a horizontal plate is threadedly connected to the surface of the screw, a cover plate is fixed to the bottom of the horizontal plate, a stirring structure is provided at the bottom of the cover plate, and a liquid inlet hopper is connected to the front and rear sides of the top of the cover plate. Publication number CN207330957U discloses a vortex oscillation mixing device, including a vortex instrument, a shockproof pad, a support shaft, a buffer pad and a fixed tray. In the upper center of the vortex instrument, a support shaft is coaxially made, and the fixed tray is horizontally fixed to the upper end of the support shaft. The buffer pad has stickiness on both sides and can be removably adhered to a culture bottle fixed tray or a well plate fixed tray. The above-mentioned oscillation device has a single motion mode and can only provide a simple oscillation mixing effect, which is prone to uneven mixing or stratification. Especially for viscous liquids, multi-layer solutions or reagents containing particles, it is difficult to achieve gentle and comprehensive uniform mixing. Violent vortex oscillations can easily generate shear force and bubbles, causing damage to sensitive samples such as cell reagents or protein reagents, affecting the reliability of experimental results.

[0004] In order to improve the above problems, the applicant filed a separate Chinese invention patent application entitled "A Multi-Degree-of-Freedom Rotating Vortex Apparatus for Complex Mixing of Reagents." The invention can drive the reagent bottle to slide in a circle around the central axis of the cylindrical housing by a rotating motor, and by activating the electric telescopic rod to drive the rack to rise and fall, so that the third gear and the gear shaft rotate to achieve reciprocating flipping or combined sliding of the reagent bottle, thereby meeting the mixing requirements of different liquids. However, the number of reagents oscillated by the above-mentioned vortex apparatus is fixed and cannot be flexibly adjusted. When mixing a small amount of solvent, the second reagent rack rotates with the device even when it is idle, which adds additional rotational weight, causing the motor to output more energy to maintain operation, resulting in unnecessary energy waste and increased operating costs over long-term use.

DETAILED DESCRIPTION Example 1

[0014] The variable load module of the present invention includes a support component, a disassembly component and a buckle component. The invention is characterized in that the support assembly is placed on the side of the cylindrical shell (1), and the support assembly is provided with two groups. The two groups of support assemblies and the two groups of adjustment placement assemblies are alternately arranged along the circumference of the cylindrical shell (1). There are multiple support assemblies in each group, and the multiple support assemblies in each group are equidistantly arranged along the axial direction of the cylindrical shell (1). The support assembly and the disassembly assembly correspond one to one, and each of the disassembly assemblies corresponds to multiple snap assemblies. The multiple snap assemblies are equidistantly arranged along the circumference of the loading and unloading shell (21) of the corresponding disassembly assembly. The snap assemblies can firmly clamp the disassembly assembly on the support assembly and facilitate disassembly. The support assembly is composed of a fixed column (18), a connecting rod (26), a truncated cone-shaped limit block (25) and a sliding block (27). One end of the fixed column (18) is fixedly connected to the outer side of the cylindrical shell (1). One end of the connecting rod (26) is fixedly connected to the other end of the fixed column (18). The truncated cone-shaped stopper (25) is fixedly connected to the other end of the connecting rod (26), and the diameter of the truncated cone-shaped stopper (25) gradually decreases from one end connected to the connecting rod (26) to the other end. Preferably, the connecting rod (26) is a hollow carbon fiber rod, the hollow portion of which is filled with shock-absorbing gel, and the two ends of the connecting rod (26) are connected to the fixed column (18) and the truncated cone-shaped limit block (25) through an integrated injection molding process. The sliding block (27) is sleeved on the connecting rod (26) and is slidably connected to the connecting rod (26). The diameter of the sliding block (27) gradually decreases and then increases from one end to the other end, and the sliding block (27) and the truncated cone-shaped limit block (25) have the same diameter near the end. The disassembly assembly consists of a loading and unloading shell (21) and a third experimental rack (20). One end of the loading and unloading shell (21) is an open structure, and the loading and unloading shell (21) is clamped on the frustum-shaped limiting block (25). Preferably, the diameter of the loading and unloading shell (21) near one end is larger than the diameter of other parts. One end of the third experimental frame (20) is fixedly connected to the other end of the loading and unloading shell (21). Preferably, the loading and unloading housing (21) is connected to the third experimental rack (20) via a hinge with an adjustable angle, and the hinge is lockable. Each of the third experimental racks (20) is evenly distributed with a plurality of third slots. Preferably, an elastic silicone sleeve is provided on the edge of each third slot of the third experimental frame (20). The buckle assembly is composed of a sliding column (19), a triangular limit block (23), a sliding groove (24) and a support spring (22). The diameter of the sliding column (19) near one end is larger than the diameter of the other parts. A triangular stop block (23) is fixedly mounted on the other end of the sliding column (19). The width of the triangular stop block (23) gradually decreases from one end connected to the sliding column (19) to the other end, and the side close to the truncated cone stop block (25) is a vertical plane. The larger diameter portion of the loading and unloading housing (21) is provided with a sliding groove (24) that matches the sliding column (19) and the triangular limit block (23). The support spring (22) is wound around the side of the sliding column (19), one end of the support spring (22) is fixedly connected to the triangular limit block (23), and the other end of the support spring (22) is fixedly connected to the sliding groove (24). When in use, initially, there is a certain distance between the sliding block (27) and the fixed column (18). When a large amount of reagents needs to be mixed, the sliding block (27) is moved toward the fixed column (18) until it is close to the fixed column (18), and the loading and unloading shell (21) is picked up, and one end of the opening is aligned with the truncated cone-shaped limit block (25) and inserted. When the loading and unloading shell (21) is pushed to slide along the truncated cone-shaped limit block (25) toward the fixed column (18), the triangular limit block (23) slides on the side of the truncated cone-shaped limit block (25), and as the diameter of the truncated cone-shaped limit block (25) increases, the support spring (22) is gradually compressed. When the triangular limit block (23) completely passes the truncated cone-shaped limit block (25), the support spring (22) plays an elastic role, so that the triangular limit block (23) is close to the side of the connecting rod (26) and is clamped between the sliding block (27) and the truncated cone-shaped limit block (25), thereby The loading and unloading shell (21) is fixedly connected to the support assembly, and the reagent tube is placed in the third slot on the third experimental rack (20). The reagent complex mixing multi-degree-of-freedom vortex instrument is driven to mix a large amount of reagents. When a small amount of solvent needs to be mixed, the loading and unloading shell (21) continues to slide toward the fixed column (18). Since the slope of the triangular limit block (23) first contacts the sliding block (27) at this time, the triangular limit block (23) gradually slides to the side of the sliding block (27). At this time, the loading and unloading shell (21) is slid toward the truncated cone limit block (25), thereby driving the sliding block (27) to fit with the truncated cone limit block (25), so that the triangular limit block (23) slides over the sliding block (27) and the side of the truncated cone limit block (25) in turn, thereby detaching from the support assembly, thereby removing the disassembly assembly and the buckle assembly, reducing the weight of the device rotating during operation, and reducing energy consumption; The connecting rod (26) is a hollow carbon fiber rod, and the hollow portion thereof is filled with a shock-absorbing gel. The two ends of the connecting rod (26) are connected to the fixed column (18) and the truncated cone-shaped limit block (25) by an integrated injection molding process. While ensuring the structural strength of the connecting rod (26), the weight is reduced, and the load when the instrument rotates is reduced. The shock-absorbing gel filled inside can effectively absorb the vibration generated when the instrument is working, and prevent the vibration from being transmitted to the disassembly components and reagents, affecting the mixing effect or damaging the reagents. The integrated injection molding process makes the connection between the connecting rod (26) and the fixed column (18) and the truncated cone-shaped limit block (25) more secure, thereby improving the overall structural stability. The loading and unloading housing (21) is connected to the third experimental rack (20) via a hinge with an adjustable angle. The hinge is lockable and can be connected via the hinge with an adjustable angle. The tilt angle of the third experimental rack (20) can be adjusted according to actual experimental requirements, so that the reagents can be better subjected to forces in different directions during the mixing process, thereby improving the mixing effect. The angle locking member can ensure that the adjusted angle remains stable. The edge of each third slot of the third experimental rack (20) is provided with an elastic silicone sleeve, which can better fix the reagent tube to prevent it from shaking or falling off during the mixing process, and at the same time avoid direct friction damage between the reagent tube and the third experimental rack (20); The purpose of being able to quickly and firmly install the disassembly component on the support component through the snap assembly is achieved to meet the requirements of different reagent mixing quantities.

A third gear (9) is fixedly mounted on one end of the gear shaft (5), and the third gear (9) is meshed with the rack (11). The adjustment placement component is composed of a first reagent rack (3) and a first slot (4). The middle height of the first reagent rack (3) is greater than the height of the two ends, and the middle position of the first reagent rack (3) is sleeved on the side surface of the gear shaft (5) close to the other end.
