Description

Technical Field

[0001] The invention relates to the technical field of oscillators, in particular to an adjustable medicine-adding oscillating device. Background Art

[0002] A dosing oscillator (also known as a drug oscillator) is a laboratory and medical device used to accelerate drug dissolution and mixing. Its core function is to replace manual operations with mechanical oscillation to improve efficiency and mixing uniformity.

[0003] At present, the dosing shield mainly adopts two methods: vortex oscillation and horizontal reciprocating oscillation, but both methods have the problem of shear force: 1. The vortex oscillator generates shear force through eccentric rotation to drive the vortex, but the internal friction of high-viscosity liquids will significantly weaken the shear force. For example, when processing blood or colloidal solutions, high viscosity will cause liquid stratification rather than full mixing; 2. Horizontal oscillation mainly promotes liquid mixing through horizontal reciprocating motion, but this movement mode has weak shear force on the bottom drug liquid, and it is difficult to form effective vortex or convection, especially for high-viscosity drug liquid or components with large density differences (such as heavy particle sedimentation). The bottom liquid is prone to stratification due to gravity, resulting in a decrease in mixing effect.

[0004] How to solve the above technical problems has become a difficult problem. Summary of the invention

[0005] The purpose of the present invention is to propose an adjustable dosing oscillating device to solve the problem that when conventional vortex oscillation and horizontal oscillation are used to oscillate liquids with excessively high viscosity, insufficient shear force occurs, resulting in reduced mixing effect.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: an adjustable drug-adding oscillating device: comprising a body, on the housing of which a reciprocating oscillating mechanism and a rotating side-swing driving assembly are fixed;

[0007] The reciprocating oscillation mechanism comprises a reciprocating driving shaft, and a connecting seat is sleeved on the driving shaft;

[0008] The connecting seat is rotatably connected to a plurality of groups of annularly distributed rotating side-swing assemblies, wherein the rotating side-swing assemblies include a rotating shaft rotatably connected to the connecting seat, and a drug tube mounting tube is rotatably connected to the rotating shaft;

[0009] The rotation and sway driving assembly includes a plurality of annularly distributed bump blocks;

[0010] The reciprocating oscillation mechanism drives the rotating shaft and the medicine tube mounting tube to reciprocate around the driving shaft through the connecting seat. The connecting seat realizes vertical shaking through the support of the shaking block. The rotating side swing driving component drives the rotating shaft to rotate and supports the medicine tube mounting tube to swing.

[0011] As a further description of an adjustable medicine adding and oscillating device of the above technology: The rotating shaft is coaxially fixed with a bevel gear;

[0012] The rotating side-sway driving assembly includes an incomplete bevel gear fixed on the machine shell. Multiple tooth areas meshing with the bevel gear are distributed on the incomplete bevel gear, and multiple annularly distributed side-sway pressing plates are fixed on the side wall of the incomplete bevel gear;

[0013] The bump blocks are annularly distributed on the upper surface of the incomplete bevel gear;

[0014] The connecting seat includes a sleeve adapted to the driving shaft, and multiple annularly distributed shaft sleeves are fixed on the outer wall of the sleeve;

[0015] The driving shaft is rotatably arranged in the shaft sleeve through a bearing;

[0016] One side of the medicine tube installation pipe is fixed with an ear plate, and the ear plate is rotatably connected to the connecting seat fixed at one end of the bevel gear through a connecting shaft, and the connecting shaft is perpendicular to the rotating shaft.

[0017] As a further description of an adjustable medicine adding and oscillating device of the above technology: The driving shaft includes a square shaft, and the sleeve is sleeved on the square shaft;

[0018] The lower end of the driving shaft is coaxially fixed with a gear, the gear meshes with a rack, multiple guide seats fixed in the machine shell are sleeved on the rack, and a driving arm with a strip-shaped hole is vertically fixed on the rack;

[0019] A servo motor is fixed in the machine shell, a crank is fixedly installed on the output shaft of the servo motor, and the dial rod of the crank is placed in the strip-shaped hole.

[0020] As a further description of an adjustable medicine adding and oscillating device of the above technology: The height of the bump block is less than the full tooth height of the tooth area and the bevel gear.

[0021] As a further description of an adjustable medicine adding and oscillating device of the above technology: Multiple groups of annularly distributed rubber plates are fixed inside the medicine tube installation pipe.

[0022] As a further description of an adjustable medicine adding and oscillating device of the above technology: An airbag pad is fixed at the bottom inside the medicine tube installation pipe.

[0023] As a further description of an adjustable medicine adding and oscillating device of the above technology: Multiple annularly distributed baffles are fixed on the machine shell, the lower end of the medicine tube installation pipe is placed at the baffles, and the surface of the baffles is wrapped with a rubber layer.

[0024] As a further description of an adjustable medicine adding and oscillating device of the above technology: The driving shaft is rotatably connected to the incomplete bevel gear through a bearing.

[0025] As a further description of an adjustable medicine adding and oscillating device of the above technology: The machine body further includes a speed regulator electrically connected to the servo motor.

[0026] In summary, due to adopting the above technology of an adjustable medicine adding and oscillating device, the beneficial effects of the present invention are as follows:

[0027] 1. When the connecting seat in rotation passes through the bump block in the present invention, the bump block lifts the connecting seat, the rotating side-swinging assembly, and the medicine tube installation tube, and when the connecting seat falls, it collides with the rotating side-swinging driving assembly, forming a vertical inertial force. The vertical impact force will be converted into the kinetic energy inside the liquid of the medicine tube, triggering local turbulence of the liquid. Compared with the eccentric rotation mode of the vortex oscillator, the turbulence generated by the vertical collision has stronger disorderliness and diffusivity, which can break the liquid stratification structure and promote the uniform distribution of shear force.

[0028] 2. When the medicine tube rotates reciprocally around the vertical line, a velocity gradient is formed in the vertical direction of the liquid, promoting the convection of the upper and lower layers; when it swings around the rotating shaft by self-rotation, the particles or high-density components in the liquid are dispersed by the centrifugal force, reducing stratification; when the medicine tube swings outward, the movement range of the liquid can be expanded, increasing the collision frequency with the pipe wall, further breaking the local eddy dead angle. The combination of the three significantly improves the mixing uniformity.

[0029] 3. In the present invention, when the bottom of the medicine tube installation tube collides with the rubber layer on the surface of the baffle, a reverse rebound force will be generated after the rubber layer collides and deforms. Furthermore, during this process, the shock wave generated by the collision will break the laminar flow state of the liquid in the medicine adding tube, triggering disordered turbulence. The turbulent vortices further intensify the collision and friction between liquid molecules, making the shear force distribution more uniform. The pressure fluctuation caused by the collision forces the liquid to flow repeatedly in the compression-expansion cycle, reducing the "dead angle" formed by the viscous resistance in the high-viscosity liquid and improving the mixing uniformity.

[0044] Next, the accompanying drawings in the embodiments of the present invention will be combined to clearly and completely describe the technology in the embodiments of the present invention. An adjustable medicine adding and oscillating device. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0045] As Figure 1 - Figure 7 shown, the present invention provides: an adjustable medicine adding and oscillating device, including a body 10, and a reciprocating oscillation mechanism 20 and a rotating side-swing drive assembly 50 are fixed on the housing 11 of the body 10;

[0046] The reciprocating oscillation mechanism 20 includes a drive shaft 21 which is arranged vertically and reciprocates. A connecting seat 30 is sleeved on the drive shaft 21 so that the connecting seat 30 can be driven to reciprocate by the reciprocating rotation of the drive shaft 21. Meanwhile, the connecting seat 30 can also move vertically along the drive shaft 21.

[0047] A plurality of groups of rotating side swing assemblies 40 distributed in an annular manner are rotatably connected to the connection seat 30. The rotating side swing assemblies 40 include a rotating shaft 41 rotatably connected to the connection seat 30 and arranged perpendicularly to the driving shaft 21. A medicine tube mounting tube 60 is rotatably connected to the rotating shaft 41. The medicine tube mounting tube 60 is used to hold the medicine tube, and the medicine tube mounting tube 60 rotates around the axis direction perpendicular to the rotating shaft 41.

[0048] The rotary side-sway driving assembly 50 includes a plurality of annularly distributed bump blocks 54;

[0049] The reciprocating oscillation mechanism 20 drives the rotating shaft 41 and the medicine tube mounting tube 60 to reciprocate around the driving shaft 21 through the connecting seat 30. The connecting seat 30 is supported by the bump block 54 to realize vertical bumping. When the rotating connecting seat 30 passes through the bump block 54, the bump block 54 lifts the connecting seat 30, the rotating side swing assembly 40, and the medicine tube mounting tube 60, and collides with the rotating side swing drive assembly 50 when the connecting seat 30 falls, forming a vertical inertial force. The vertical impact force will be converted into kinetic energy inside the medicine tube liquid, causing local turbulence of the liquid. Compared with the eccentric rotation mode of the vortex oscillator, the turbulence generated by the vertical collision has stronger disorder and diffusivity, which can break the layered structure of the liquid and promote the uniform distribution of shear force;

[0050] At the same time, during this process, the side swing driving assembly 50 is rotated to drive the rotating shaft 41 to rotate, and at the same time, the medicine tube mounting tube 60 is supported to swing;

[0051] When the medicine tube reciprocates around the vertical line, the liquid forms a velocity gradient in the vertical direction, promoting convection between the upper and lower layers; when it rotates around the rotating axis 41, the particles or high-density components in the liquid are dispersed by centrifugal force to reduce stratification; the medicine tube swings outward to expand the movement range of the liquid, increase the collision frequency with the tube wall, and further break the local eddy current dead corners. The combination of the three significantly improves the mixing uniformity.

[0052] like Figure 2 , Figure 3 , Figure 5As shown, a bevel gear 42 is coaxially fixed to a rotating shaft 41; a rotating side swing drive assembly 50 includes an incomplete bevel gear 51 fixed to the machine housing 11. The incomplete bevel gear 51 is fixed to the upper surface of the machine housing 11 by multiple support rods 53, and multiple groups of tooth areas 511 meshing with the bevel gear 42 are distributed on the incomplete bevel gear 51. A toothless area is formed between two adjacent tooth areas 511. A drive shaft 21 is coaxially arranged with the incomplete bevel gear 51. When the drive shaft 21 drives the rotating shaft 41 to rotate around the bevel gear 42, and when the bevel gear 42 meshes with the tooth area 511, at this time, the medicine tube mounting tube 60 deflects around the rotating shaft 41. Multiple annularly distributed side swing pressing plates 52 are fixed to the side wall of the incomplete bevel gear 51.

[0053] Bump blocks 54 are fixed and annularly distributed on the upper surface of the incomplete bevel gear 51. The cross-section of the bump block 54 is a triangular structure with the vertex facing upward. When the sleeve 31 passes over the bump block 54, the sleeve 31 moves upward along the slope of the bump block 54, causing the sleeve 31 to slide upward along the square shaft 211. When the sleeve 31 moves downward along the slope and collides with the incomplete bevel gear 51, at this time, the bumping action of the medicine tube mounting tube 60 can be realized;

[0054] The connecting seat 30 includes a sleeve 31 adapted to the drive shaft 21, and multiple annularly distributed shaft sleeves 32 are fixed to the outer wall of the sleeve 31;

[0055] The drive shaft 21 is rotatably arranged in the shaft sleeve 32 through a bearing;

[0056] An ear plate 63 is fixed to one side of the medicine tube mounting tube 60. The ear plate 63 is rotatably connected to an adapter seat 421 fixed to one end of the bevel gear 42 through a connecting shaft 631. The connecting shaft 631 is perpendicular to the rotating shaft 41. The cross-section of the side swing pressing plate 52 is a triangular structure with the vertex facing outward. During the process of the medicine tube mounting tube 60 rotating around the drive shaft 21, the slope of the side swing pressing plate 52 presses the medicine tube mounting tube 60 to swing laterally around the rotating shaft 41.

[0057] As Figure 2 、 Figure 3 、 Figure 5 shown, the drive shaft 21 includes a square shaft 211, and the sleeve 31 is sleeved on the square shaft 211. Therefore, when the drive shaft 21 rotates, the sleeve 31 can be driven to rotate through the square shaft 211, and the sleeve 31 can slide up and down along the square shaft 211;

[0058] As Figure 4 shown, a gear 22 is coaxially fixed to the lower end of the drive shaft 21. The drive shaft 21 is rotatably arranged on the machine housing 11 through a bearing. The gear 22 meshes with a toothed plate 23. Multiple guide seats 231 fixed in the machine housing 11 are sleeved on the toothed plate 23. The toothed plate 23 is limited and guided by the multiple guide seats 231. A drive arm 24 with a strip hole 241 is vertically fixed to the toothed plate 23;

[0059] A servo motor 26 is fixed inside the housing 11. The output shaft of the servo motor 26 is fixedly installed with a crank 25, and the lever of the crank 25 is placed inside the strip-shaped hole 241;

[0060] The output shaft of the servo motor 26 drives the crank 25 to rotate. The lever of the crank 25 drives the driving arm 24 to linearly slide, and the lever slides inside the strip-shaped hole 241. When the crank 25 reciprocates linearly, it drives the toothed plate 23 to linearly reciprocate. Furthermore, through the meshing of the toothed plate 23 and the gear 22, the reciprocating rotation of the drive shaft 21 is realized.

[0061] As Figure 3 、 Figure 4 shown, since the height of the bump block 54 is less than the full tooth height of the tooth area 511 and the bevel gear 42, it can be ensured that when the sleeve 31 passes through the highest point of the bump block 54, the bevel gear 42 and the tooth area 511 are still in the meshing state, avoiding the problem of tooth collision between the bevel gear 42 and the tooth area 511 when the bevel gear 42 descends after tooth disengagement.

[0062] As Figure 6 、 Figure 7 shown, multiple groups of annularly distributed rubber plates 61 are fixed inside the medicine tube installation tube 60. The medicine adding tube is inserted into the multiple annularly distributed rubber plates 61. Firstly, the rubber plates 61 increase the friction coefficient with the medicine adding tube, avoiding the problem of the up and down movement of the medicine adding tube caused by vertical collision; secondly, it plays a buffering role during the side swing process to avoid directly colliding with the inner wall of the medicine tube installation tube 60.

[0063] As Figure 7 shown, an airbag pad 62 is fixed at the bottom inside the tube of the medicine tube installation tube 60. Through the airbag pad 62, the bottom of the medicine adding tube can be buffered and protected, avoiding the medicine adding tube from moving downward and colliding with the bottom wall of the medicine tube installation tube 60.

[0064] As Figure 2 ​As shown in the figure, a plurality of baffles 13 annularly distributed around the drive shaft 21 are fixed on the casing 11. The lower end of the medicine tube installation tube 60 is placed at the baffle 13. When the drive shaft 21 and the shaft sleeve 32 rotate clockwise, at this time, under the meshing action of the incomplete bevel gear 51 and the bevel gear 42, the medicine tube installation tube 60 rotates clockwise around the rotating shaft 41. When the bottom of the medicine tube installation tube 60 collides with the baffle 13, the surface of the baffle 13 is wrapped with a rubber layer. The rubber layer serves two purposes: one is to buffer the collision of the medicine tube installation tube 60, and the other is that after the rubber layer deforms due to the collision, a reverse rebound force will be generated. During this process, the shock wave generated by the collision will break the laminar flow state of the liquid in the medicine adding tube, triggering disordered turbulence. The turbulent vortices further intensify the collision and friction between liquid molecules, making the shear force distribution more uniform. The pressure fluctuation caused by the collision forces the liquid to flow repeatedly in the compression-expansion cycle, reducing the "dead corners" formed by the viscous resistance in the high-viscosity liquid and improving the mixing uniformity.

[0065] As Figure 3 shown, the drive shaft 21 and the incomplete bevel gear 51 are rotatably connected through a bearing. Thus, the incomplete bevel gear 51 can support the drive shaft 21 to improve the stability of the drive shaft 21 during rotation.

[0066] As Figure 2 shown, the machine body 10 further includes a speed regulator 12 electrically connected to the servo motor 26. The speed regulator 12 directly adjusts the motor speed by changing the pulse frequency and quantity sent to the servo motor 26, thereby realizing the adjustment of the rotation, swing, vertical collision, and lateral collision frequencies of the medicine tube installation tube 60 and the medicine adding tube installed inside it.

[0067] Working principle: The sealed medicine adding tube filled with liquid is loaded into the medicine tube installation tube 60 and clamped and limited by multiple rubber plates 61.

[0068] Subsequently, the equipment is started, and the speed of the servo motor 26 is adjusted through the speed regulator 12. The output shaft of the servo motor 26 drives the crank 25 to rotate. The lever of the crank 25 drives the driving arm 24 to linearly slide, and the lever slides in the strip hole 241. When the crank 25 reciprocally linearly slides, it drives the toothed plate 23 to linearly reciprocate. When the toothed plate 23 linearly reciprocates, it drives the drive shaft 21 to reciprocally rotate through meshing with the gear 22.

[0069] When the drive shaft 21 reciprocally rotates, it drives the square shaft 211 to reciprocally rotate. The square shaft 211 drives the sleeve 31 to rotate accordingly. And during the process of the sleeve 31 rotating around the drive shaft 21, when the bevel gear 42 meshes with the tooth area 511, the medicine tube installation tube 60 and the medicine adding tube inside it rotate accordingly.

[0070] During the rotation of the medicine tube installation tube 60, at this time, under the slope extrusion of the side swing extrusion plate 52, the medicine tube installation tube 60 can swing and turn with the connecting shaft 631 as the axis.

[0071] Meanwhile, during the rotation of the sleeve 31, when passing through the bump 54, the sleeve 31 moves from the bottom of the slope of the bump 54 to the top of the slope, lifting the sleeve 31. Then the sleeve 31 moves from the top of the slope to the bottom of the slope along the slope of the bump 54 and collides with the incomplete bevel gear 51.

[0072] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
