Description

Technical Field

[0001] The invention relates to the technical field of bioengineering, and in particular to an automated aseptic shallow dish inoculation device. Background Art

[0002] Bacterial cellulose is a material with broad application prospects. In its production process, the inoculation step is crucial. At present, the traditional inoculation steps in this field are mostly completed manually. Specifically, operators need to use tools such as inoculation needles and culture media to perform manual operations under strict sterile conditions.

[0003] However, this artificial inoculation method has many disadvantages. First, it has extremely high requirements for the sterile environment. Any slight omission may lead to contamination, which seriously affects the production quality of bacterial cellulose. It is difficult and costly to maintain such a highly sterile environment in actual operation. Second, the entire operation process is extremely cumbersome, involving many steps and delicate operations, which not only consumes a lot of manpower and time, but also has high labor intensity, which greatly limits the improvement of production efficiency. Third, artificial inoculation is easily disturbed by environmental factors (such as temperature, humidity, air quality, etc.) and human factors (such as the skill level, proficiency, concentration, etc. of the operator), and it is difficult to ensure the stability and consistency of the inoculation operation. Fourth, in terms of the control of the inoculation amount, it is difficult to achieve precise control by manual operation, which makes the bacterial cellulose products produced have a large risk of differences in quality and performance, and it is difficult to ensure the consistency of the products, and it is impossible to meet the market's requirements for product quality stability.

[0004] More importantly, with the growing demand for bacterial cellulose applications in various fields, large-scale industrial production has become an inevitable trend. However, due to its own limitations, the existing artificial inoculation method cannot achieve automation and continuity of the inoculation process, and is far from meeting the urgent needs of industrial large-scale production for efficient, stable and accurate inoculation.

The liquid inlet end of the culture medium peristaltic pump 21 is connected to the inner bottom of the culture medium storage tank 19, and the liquid outlet end of the culture medium peristaltic pump 21 is connected to the culture medium addition tube 22. The left and right inner walls of the shell 1 are connected to threaded rods 12 that rotate together. A transverse block 24 is threadedly connected to the threaded rod 12, and an inoculation needle 27 is fixedly connected to the lower end of the transverse block 24. The inoculation needle 27 is connected to the liquid outlet of the seed liquid injection pump 26 through a hose 41. Two sterilization lamps 18 are installed on the inner top of the outer shell 1, and a positive pressure air supply filter assembly 11 is installed on the right side of the outer shell 1. The positive pressure air supply filter assembly 11 is equipped with an H14 grade filter element, so that the operating area becomes a vertical flow clean area to prevent external pollution from entering. Two baffles are preset on the outside. After each culture plate enters the outer shell 1, the two feed ports 7 are blocked and sealed by the baffles.

[0033] Among them, a rotating cylinder 35 is provided in the outer shell 1, a notch 38 is provided on the right side of the rotating cylinder 35, a plurality of electric heating plates 36 and an ultraviolet lamp 37 are provided on the inner wall of the rotating cylinder 35, the inoculation needle 27 is located in the rotating cylinder 35, the power of the ultraviolet lamp 37 is 10W, the temperature of the electric heating plate 36 is 200°C, and the running time for each disinfection is more than 2S. It also includes a rotating sterilization component, which includes a fixed rod 32 fixed on the inner wall of the left side of the outer shell 1, a fixed ring 31 is fixedly connected to the right side of the fixed rod 32, a rotating groove is provided in the fixed ring 31, a rotating ring 40 is provided in the rotating groove, the inner wall of the rotating ring 40 is fixedly connected to the rotating cylinder 35, and a plurality of tooth edges 39 are fixedly connected to the outer wall of the rotating cylinder 35, a fixed block 29 is fixedly connected to the right side of the seed liquid storage tank 23, and the lower end of the fixed block 29 is rotatably connected to the rotating rod 30, and a second gear 33 is provided on the rotating rod 30, and the second gear 33 is meshed with the plurality of tooth edges 39.

[0034] Among them, a delayed rotation component is provided on the left side of the shell 1, and the delayed rotation component includes a rectangular box 5 arranged on the left side of the shell 1, and the left side of the threaded rod 12 extends into the rectangular box 5. The inner bottom and inner top of the rectangular box 5 are rotatably connected with a vertical rod 14 together, and a threaded layer is provided on the vertical rod 14. The vertical rod 14 and the threaded rod 12 are both provided with a first bevel gear 13. A lifting block 15 is threadedly connected to the vertical rod 14, and a first electromagnet is embedded in the lifting plate 15. The lifting block 15 is slidably connected to the inner wall of the rectangular box 5, and a moving plate 16 is slidably connected in the rectangular box 5. The moving plate 16 is made of iron material and is provided with a controller. When the transverse block 24 moves to the right to the specified position, the staff controls the first electromagnet to be energized through the controller. After the first electromagnet is energized, it generates an attractive force on the moving plate 16, and the lower end of the moving plate 16 is elastically connected to the inner bottom of the rectangular box 5 through the first spring 17 The vertical rod 14 passes through the movable plate 16, and a pressure rod is fixedly connected to the right side of the transverse block 24. A pressure sensor 20 is fixedly connected to the left inner wall of the shell 1. When the transverse block 24 moves back to its original position, the pressure sensor 20 is squeezed to generate an electrical signal transmitted to the controller. The controller controls the first electromagnet to cut off the power. A rack 9 is fixedly connected to the lower end of the movable plate 16, and a transmission rod 6 is rotatably connected to the left inner wall of the shell 1. A first gear 8 is provided on the transmission rod 6, and a one-way bearing is provided between the transmission rod 6 and the first gear 8. The one-way bearing has the characteristics of free rotation in one direction and locking in one direction, so that when the rack 9 moves up, the first gear 8 cannot rotate the transmission rod 6. When the rack 9 moves down, the transmission rod 6 is driven to rotate by the first gear 8. The first gear 8 and the rack 9 are meshed with each other. The transmission rod 6 and the rotating rod 30 are both provided with a second bevel gear 34 meshing with each other.

[0035] Among them, the inner walls of the front and rear sides of the shell 1 are fixedly connected with strip boxes 47, the inner walls of the opposite sides of the two strip boxes 47 are embedded with second electromagnets 49, and sliders 48 are slidably connected in the two strip boxes 47. A portion of the slider 48 close to the corresponding second electromagnet 49 is made of magnetic material, and the two sliders 48 are elastically connected to the adjacent sides of the corresponding second electromagnet 49 through a second spring. The adjacent sides of the two sliders 48 are fixedly connected with sponge blocks 28, and the left inner wall of the shell 1 is fixedly connected with a transverse plate 43, and the lower end of the transverse plate 43 is fixedly connected with a trapezoidal block 44, a magnetic block 46 and two conductive strips 45, and the upper end of the transverse block 24 is fixedly connected with a damping box 25. An iron block 42 is slidably connected in the damping box 25. When the iron block 42 moves to the right, it will not contact the two conductive strips 45. After the transverse block 24 moves to the right to the specified position, the magnetic block 46 attracts the iron block 42 to move upward. When the transverse block 24 moves to the left, the magnetic block 46 separates from the iron block 42. At this time, the iron block 42 will not move downward due to the large friction with the inner wall of the damping box 25, so that the iron block 42 will contact the two conductive strips 45. The two second electromagnets 49 are energized to generate a repulsive force on the two sliders 48. A power supply is provided on the outer shell 1. The iron block 42 and the two conductive strips 45 form a conductive unit. The power supply, the conductive unit and the two second electromagnets 49 form a loop through wires.

[0036] The functional principle of the present invention can be explained through the following operation mode: the culture tray is placed on two conveyor belts 4, and the operation of the conveying motor of the prior art drives the two conveyor belts 4 to operate, so as to move the culture tray into the housing 1. When the culture tray is moved to a suitable position, the two lifting motors 50 are controlled to operate, so that the bracket 51 moves up to lift the culture tray to a suitable height. The staff controls the output shaft of the driving motor 10 to rotate clockwise, drives the inoculation needle 27 to move right to a specified position through the lateral movement block 24, controls the seed liquid injection pump 26 and the culture medium peristaltic pump 21 to operate, and quantitatively adds the culture medium and seed liquid into the culture tray;

[0037] When the lateral block 24 moves to the right, the vertical rod 14 is driven to rotate by the first bevel gear 13, and the vertical rod 14 rotates to move the lifting block 15 downward, so that the lifting block 15 contacts the upper end of the moving plate 16. When injecting the culture medium and the seed liquid, the staff controls the operation of the first electromagnet through the controller, so that the first electromagnet generates an attractive force on the moving plate 16. When the injection is completed, the output shaft of the driving motor 10 is controlled to rotate counterclockwise, so that the lateral block 24 moves to the left.

[0038] When the threaded rod 12 rotates counterclockwise, the two first bevel gears 13 drive the vertical rod 14 to rotate in the opposite direction, so that the lifting block 15 drives the movable plate 16 to move up, and the movable plate 16 moves up to make the rack 9 move up. Since a one-way bearing is provided between the first gear 8 and the transmission rod 6, the one-way bearing has the performance of rotating in one direction and locking in the other direction, so that the rotation of the first gear 8 will not drive the transmission rod 6 to rotate. When the transverse block 24 moves back to its original position, the pressure rod will squeeze the pressure sensor 20, and the pressure sensor 20 will generate an electrical signal transmitted to the controller. The controller controls the first electromagnet to cut off the power. After the first electromagnet is powered off, it no longer has an attractive force on the movable plate 16. Under the action of the first spring 17, the movable plate 16 drives the rack 9 to move down. At this time, the transmission rod 6 is driven to rotate through the first gear 8, and then the rotating rod 30 is driven to rotate under the action of the two second bevel gears 34. Since the second gear 33 is in a meshing state with multiple tooth edges 39, the rotating cylinder 35 is driven to rotate.

[0039] Each time the inoculation needle 27 moves to the left after injecting the seed liquid, it will enter the rotating cylinder 35 through the notch 38, and the pressure sensor 20 will be squeezed to generate an electrical signal transmitted to the controller, and the controller will control the multiple electric heating plates 36 and the ultraviolet lamp 37 to operate for a period of time to disinfect the inoculation needle 27. Since the rotating cylinder 35 is in a rotating state, it is ensured that each position of the inoculation needle 27 can be evenly disinfected.

[0040] When the traverse block 24 moves right, the iron block 42 is far away from the cross plate 43, and the iron block 42 will not contact the two conductive strips 45, so that when the traverse block 24 moves right, the two second electromagnets 49 will not be energized. When the traverse block 24 moves to the specified position, the magnetic block 46 will attract the iron block 42, so that the iron block 42 moves up. When the traverse block 24 moves left, the iron block 42 will separate from the magnetic block 46. Since the inner wall of the damping box 25 is relatively rough, the iron block 42 will not move down and reset. When the traverse block 24 moves left, the iron block 42 will contact the two conductive strips 45, and the two second electromagnets 49 will be energized.

[0041] After the two second electromagnets 49 are energized, they exert a repulsive force on the corresponding sliders 48, so that the two sliders 48 drive the corresponding sponge blocks 28 to move relative to each other and squeeze together. When the lateral block 24 drives the inoculation needle 27 to move left, the inoculation needle 27 will move between the two sponge blocks 28, so that the sponge blocks 28 absorb the seed liquid adhered to the inoculation needle 27. When the inoculation needle 27 is separated from the two sponge blocks 28, the iron block 42 is no longer in contact with the two conductive strips 45. Under the action of the two second springs, the sliders 48 and the sponge blocks 28 are reset. As the lateral block 24 continues to move, the iron block 42 will contact the trapezoidal block 44, so that the iron block 42 enters the damping box 25 by mutual squeezing.

[0042] When the inoculation is completed, the lifting motor 50 is controlled to retract, so that the bracket 51 moves downward, and the inoculated culture tray is placed on the two conveyor belts 4, and the culture tray is transported to the right side of the housing 1 by the operation of the conveyor belts 4.

[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
