Abstract
Description
Technical Field
[0001] This invention relates to the field of plate culture equipment technology, specifically to an integrated machine for automatic opening, filling, closing, and shaking of disposable plate culture media. Background Technology
[0002] Plate culture medium is the most commonly used form of solid culture medium for obtaining pure cultures of microorganisms. It is a solid surface of culture medium formed in a sterile petri dish after the solid medium has cooled and solidified. It is often simply called a plate culture medium, also known as a flat culture medium or plate culture medium. Plate culture medium is often used for single spore isolation, measuring mycelial growth rate, observing colony morphology, antagonism experiments, and measuring the number of miscellaneous bacteria in the inoculation space.
[0003] CN207826623U discloses a filling device for a plate culture medium filling line, comprising a conveyor belt with support legs at its lower end, support columns fixedly connected to the front and rear sides of the upper end of the conveyor belt, support rods fixedly connected to the upper ends of the support columns, a connecting rod fixedly connected to the middle of the right end of the support rods, a first cylinder fixedly connected to the left side of the lower end of the connecting rods, and a transmission rod connected to a support slide rod at the middle of the right end of the first cylinder. The support slide rod includes a cylindrical contact, contact balls, and a spring plate. The lower end of the support slide rod is embedded with the ball balls, and the upper part of the support slide rod is inserted into a slide groove via a slider. The right end of the inner cavity of the slide groove is embedded with a contact plate. This filling device for a plate culture medium filling line, through the spring plate and pressure plate structure, makes the connection between the cylindrical contact and the contact plate more stable; through the sealing plate and electromagnet structure, the equipment driver is simplified.
[0004] However, in actual production, existing disposable plate culture media still occasionally pose a risk of contamination due to the opening of the cap and exposure to laminar flow. There is no machine that can integrate opening, filling, and closing the cap in one step to meet customer needs. On the other hand, during the actual filling process, the high viscosity and poor flowability of the culture medium liquid require increasing the actual filling volume to achieve uniformity, which increases costs and makes it impossible to reduce the amount to be filled, thus increasing production costs and greatly reducing practicality. Summary of the Invention
[0005] The purpose of this invention is to provide an integrated machine for automatic opening, filling, closing, and shaking of disposable plate culture media. This addresses the issues raised in the background section regarding the risk of contamination that still exists in the actual production process of existing disposable plate culture media due to the opening and exposure to laminar flow. There is no machine that can integrate opening, filling, and closing to meet customer needs. Furthermore, during the actual filling process, the high viscosity and poor flowability of the culture medium necessitate increasing the actual filling volume for uniform filling, thus increasing costs and preventing the reduction of the required filling volume, thereby significantly reducing practicality.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated machine for automatic opening, filling, closing, and shaking of disposable plate culture media, comprising a support frame, a worktable connected above the support frame, a baffle connected to the upper end of the worktable, a material hopper disposed between the baffles, a partition connected to one side of the material hopper, a push plate disposed below the partition, a door frame connected above the support frame, a high-efficiency blower connected above the door frame, a touch screen disposed on one side of the door frame, an upper pressure plate connected to one side of the worktable, a partition strip disposed at the lower end of the upper pressure plate, a peristaltic pump body disposed at the rear end of the touch screen, a peristaltic pump head mounted at the front end of the peristaltic pump body, the peristaltic pump head being connected to a filling needle via a silicone tube, the filling needle being mounted on a needle holder, a waste trough disposed below the filling needle, a vibrating plate disposed at the front end of the worktable, a vibration mechanism disposed below the vibrating plate, and a pushing mechanism disposed inside the worktable.

[0010] Preferably, the pushing mechanism includes a first guide roller, a second guide roller, a synchronous pulley, a synchronous belt, a cylinder, a motor, a guide block, a pusher guide block connecting plate, a hook connecting block, a hook shaft, a hook block, and a hook block mounting plate. The first guide roller, the guide block, and the pusher guide block connecting plate are connected by a cylinder. The second guide roller is connected by the synchronous pulley, the synchronous belt, the motor, the hook connecting block, the hook shaft, the hook block, and the hook block mounting plate.
[0011] Preferably, the vibration mechanism includes an oscillating motor, an eccentric shaft, a connecting block, a connecting plate, a rocking plate, a synchronous pulley, and a synchronous belt. The eccentric shaft is provided at the upper end of the oscillating motor and is connected to the transmission end of the oscillating motor. The connecting block is provided at the upper end of the eccentric shaft and is connected to the eccentric shaft via a rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. This automatic open, fill, close, and shaker for disposable plate culture media uses a cylinder to drive the guide block and pusher plate connecting plate to move horizontally, which in turn drives the pusher plate to move, achieving reciprocating motion. This pusher plate opens the top of the culture dish, and the motor drives the synchronous pulley and synchronous belt to rotate, which in turn drives the hook plate connecting block, hook plate shaft, hook plate block, and hook plate mounting plate to move horizontally, hooking the bottom of the culture dish and achieving reciprocating motion. This facilitates the transfer of the culture dish to the next process. The automatic opening and closing of the culture dish is achieved by driving the pusher plate to move. At the same time, the culture dish is filled through the filling needle, achieving a high degree of automation and effectively avoiding bacterial infection.
[0015] 2. This disposable plate culture medium automatic opening, filling, closing, and shaking integrated machine, through the setting of the vibration mechanism, moves the culture dish to the upper end of the vibration plate. The vibration motor drives the step wheel and step belt to control the eccentric shaft and work. The eccentric shaft drives the shaking plate to shake, vibrating and evenly mixing the liquid inside the culture dish. This vibration makes the liquid inside the culture dish more evenly poured, greatly improving its practicality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figure 1-5This invention provides a technical solution: an automatic opener, filler, closeer, and vibrator for disposable plate culture media, comprising a support frame 1, a workbench 2 connected above the support frame 1, baffles 3 connected to the upper end of the workbench 2, a material hopper 4 disposed between the baffles 3, a partition 5 connected to one side of the material hopper 4, a pusher plate 6 disposed below the partition 5, a door frame 7 connected above the support frame 1, a high-efficiency blower 16 connected above the door frame 7, a touch screen 15 disposed on one side of the door frame 7, an upper pressure plate 8 connected to one side of the workbench 2, a partition strip 9 disposed at the lower end of the upper pressure plate 8, a peristaltic pump body 13 disposed at the rear end of the touch screen 15, a peristaltic pump head 14 mounted at the front end of the peristaltic pump body 13, the peristaltic pump head 14 being connected to a filling needle 11 via a silicone tube, the filling needle 11 being mounted on a needle holder 12, a waste trough 17 disposed below the filling needle 11, and a vibrating plate 10 disposed at the front end of the workbench 2. A vibration mechanism 18 is installed below the worktable 2, and a pushing mechanism 19 is installed inside the worktable 2. First, the high-efficiency fan 16 is turned on, and the culture dish is placed into the storage tank 20 inside the material box 4. Next, the pusher plate 6 pushes the culture dish forward to the connection between the upper pressure plate 8 and the lower partition 9. At this time, the bottom of the culture dish is automatically separated, the pusher plate 6 returns to the starting position, and then the motor 1906 moves the bottom of the dish forward to the filling position through the hook block 1911. The system controls the peristaltic pump head 14 and the filling needle 11 to automatically fill. After filling is completed, the pusher plate 6 pushes the dish again to push out the next row of culture dishes until the bottom of this row of dishes is automatically closed to the bottom of the upper row of dishes. At this time, the motor 1906 moves the bottom of the dish forward to the filling position through the hook block 1911, and the system automatically fills. At this time, the culture dish that has completed the filling and closing action is pushed to the vibration mechanism 18, and the vibration motor 1801 is automatically turned on to shake the culture dish.

[0032] Working principle: First, turn on the high-efficiency fan 16 and place the culture dish into the storage tank 20 inside the material box 4. Next, the pusher plate 6 pushes the culture dish forward into the connection between the upper pressure plate 8 and the lower partition strip 9. At this time, the bottom of the culture dish automatically separates, and the pusher plate 6 returns to the starting position. Then, the motor 1906 moves the bottom of the dish forward to the filling position through the hook block 1911. The system controls the peristaltic pump head 14 and the filling needle 11 to automatically fill. After filling is completed, the pusher plate 6 pushes the dish again to push out the next row of culture dishes until the lid of this row of dishes automatically closes to the bottom of the upper row of dishes. At this time, the motor 1906 moves the bottom of the dish forward to the filling position through the hook block 1911, and the system automatically fills. At this time, the culture dishes that have completed the filling and closing action are pushed to the vibration mechanism 18. The vibration motor 1801 automatically turns on to shake the culture dishes, and this cycle repeats.
