Description

Technical Field

[0001] This invention relates to the field of culture medium preparation for edible and medicinal fungi, and more specifically to a production line for preparing culture medium for edible and medicinal fungi. Background Technology

[0002] Cordyceps flower, also known as North Cordyceps or Cordyceps militaris, has some similarities in composition to Cordyceps sinensis. Cordyceps flower, along with ginseng and deer antler, is considered one of the three major tonics in China. As a precious edible and medicinal fungus, the optimization of its production process has always been a hot topic in the industry research against the backdrop of rapid development in modern agricultural technology.

[0003] The production process of Cordyceps militaris includes the preparation of spawn → preparation of culture medium → sterilization and inoculation → mycelial growth on racks → management of plant growth → harvesting → storage. In the preparation of the Cordyceps militaris culture medium, the materials required include solid grains and liquid culture solution. Accurate control of the material ratio is necessary, and the preparation must be completed in specific culture medium containers. After filling, the containers need to be sealed with a film before sterilization and inoculation can proceed. Furthermore, considering the needs of subsequent operations, the film in the culture medium containers needs to be fixed to the opening using a leather sleeve. In existing technologies, all of the above operations must be performed manually, which is not only labor-intensive but also has low production efficiency. In addition, the size and specifications of culture medium basins are strictly required and they are usually stacked together for storage. In the current technology, the main method is to manually separate the stacked culture medium basins one by one. Taking the 330mm×330mm×108mm plastic basins commonly used in production to hold culture medium materials as an example, each standard factory has a single batch capacity of 100,000 basins. Currently, the production line adopts a 4-person group operation method, and the manual laborer needs to complete 800 to 1,000 basins per hour, which further increases the labor intensity.

[0058] like Figures 1-27 As shown, the present invention includes a transmission line 6 and a tray-separating mechanism 1, a raw material feeding mechanism 2, and a main frame 7 arranged sequentially along the transmission direction of the transmission line 6, wherein... Figures 2-6As shown, the pot separating mechanism 1 includes a pot rack 101, a pot separating assembly 103, and a suction cup assembly 105. Culture medium pots 8 are stacked at an angle on the pot rack 101, and the lower output end of the pot rack 101 is provided with the pot separating assembly 103 for separating the culture medium pots 8 on the pot rack 101 one by one. The suction cup assembly 105 is provided with swingable suction cups 1053, and the separated individual culture medium pots 8 are adsorbed by the suction cups 1053 and moved to the transmission line 6 by swinging. Figures 7-10 As shown, the raw material feeding mechanism 2 includes a solid hopper 202, a solid discharge mechanism 201, and multiple liquid feed pipes. The solid discharge mechanism 201, which controls the amount of solid material injected into the culture medium basin 8, is located at the lower end of the solid hopper 202. Each liquid feed pipe has a liquid outlet at its upper end for injecting liquid material into the culture medium basin 8, and each liquid feed pipe is equipped with a flow control valve to control the output of the liquid material. The flow control valve is a commercially available product, such as a liquid flow valve from the Shanghai Julang brand. Figures 11-25 As shown, the main frame 7 is equipped with a film covering mechanism 3 and a film covering fixing mechanism 4. After passing through the film covering mechanism 3, the culture medium tray 8 completes the opening covering film operation. The main frame 7 is equipped with a leather sleeve screening mechanism 5.

The transmission line 6 is a commercially available product, such as the transmission line of the Dalian Jialin brand.

[0059] like Figures 2-6 As shown, the basin-dividing mechanism 1 includes a basin-dividing cylinder 1031 and first blades 1033 and transmission plates 1034 arranged alternately along the circumferential direction of the output end of the basin holder 101. The first blade 1033 includes a blade body 10332 and a blade side rod 10331 located on one side of the blade body 10332. The ends of the blade body 10332 and the blade side rod 10331 are respectively hinged to the ends of the corresponding transmission plates 1034. Each transmission plate 1034 is driven to swing by the basin-dividing cylinder 1031. Each first blade 1033 is provided with a second blade 1035, such as... Figures 4-5 As shown, the pot-separating mechanism 1 achieves pot-separating operation by driving the first blade 1033 and the second blade 1035 of each group to move through the pot-separating cylinder 1031.

[0060] like Figures 2-5As shown, the front end of the basin stand 101 is provided with a basin assembly mounting plate 102, and the basin assembly 103 is mounted on the basin assembly mounting plate 102. A mounting support plate 1022 is provided on one side of the basin assembly mounting plate 102, and the lower end of the basin cylinder 1031 is hinged to the mounting support plate 1022. A drive support plate 1032 is provided on the outer side of the transmission plate 1034 closest to the basin cylinder 1031, and the upper end of the basin cylinder 1031 is hinged to the drive support plate 1032. Additionally, as shown... Figure 4 As shown, each opening edge of the tray-separating assembly mounting plate 102 is equipped with a limiting plate 1021. The limiting plate 1021 ensures that only culture medium trays 8 of the required size can pass through. Furthermore, suitable sensors can be installed on the limiting plate 1021 as needed.

Both the position detection sensor and the counting sensor are commercially available products; for example, sensors from the Omron brand can be used.

[0061] like Figures 2-3 and Figure 6 As shown, a suction cup assembly mounting bracket 104 is provided on one side of the output end of the basin stand 101, and the suction cup assembly 105 is disposed on the suction cup assembly mounting bracket 104. Figure 2 and Figure 6 As shown, the suction cup assembly 105 includes a suction cup driving cylinder 1051 and a rotating connecting plate 1052. The rear end of the suction cup driving cylinder 1051 is hinged to a hinge seat 1041 located on the suction cup assembly mounting frame 104. The front end of the suction cup driving cylinder 1051 is hinged to the middle of the rotating connecting plate 1052. The rear end of the rotating connecting plate 1052 is hinged to the front end of the suction cup assembly mounting frame 104. A suction cup frame 10531 is provided at the front end of the rotating connecting plate 1052, and each suction cup 1053 is mounted on the suction cup frame 10531. A suction cup tube 10532 is provided on one side of the suction cup frame 10531 and connected to a vacuum device. When a single culture medium container 8 is separated from the other containers by the container separating assembly 103, as... Figure 3 As shown, the suction cup 1053 in the suction cup assembly 105 adsorbs the bottom of the culture medium basin 8 and drives the rotating connecting plate 1052 to rotate through the suction cup drive cylinder 1051 to transfer it to the transmission line 6. Then the transmission line 6 sends the culture medium basin 8 to the raw material injection mechanism 2 to realize the injection process of solid (grain) material and liquid (culture solution) material.

[0062] like Figure 10As shown, the lower end of the solid hopper 202 of the raw material feeding mechanism 2 is provided with a hopper outlet 2021, such as... Figure 9 As shown, the solid material discharge mechanism 201 includes a material box 2011 that can move left and right, and the material box 2011 is provided with a material box discharge port 2017. During operation, the left and right movement of the material box 2011 can change the number or area of ​​alignment between the material box discharge port 2017 and the hopper discharge port 2021, thereby changing the discharge flow rate of the solid material to achieve the adjustment purpose. When the material box discharge port 2017 and the hopper discharge port 2021 are completely misaligned, the remaining part of the material box 2011 blocks the hopper discharge port 2021, preventing the solid material from being discharged and falling, thus achieving the solid material discharge shut-off function. A solid material flow meter can be installed inside the material box discharge port 2017 to detect the discharge volume in real time, and the control system can calculate and control the movement of the material box 2011 based on the detection data. The solid material flow meter is a commercially available product, such as a solid flow meter produced by Wuhan Shengke Electric Technology Co., Ltd.

[0063] like Figure 7 As shown, the raw material injection mechanism 2 is mounted on a mounting frame 205, and the transmission line 6 passes through the mounting frame 205. After the culture medium basin 8 is transported to the injection station below the solid discharge mechanism 201 via the transmission line 6, the liquid discharge nozzles at the upper ends of each liquid pipe are aligned with the culture medium basin 8 to achieve liquid material injection. A first mounting bracket 2051 is provided in the middle of the mounting frame 205, and the solid discharge mechanism 201 is mounted on the first mounting bracket 2051. A second mounting bracket 2052 is provided at the lower end of the mounting frame 205, and the drive pump 206 of each liquid pipe is mounted on the second mounting bracket 2052.

[0064] like Figures 8-9 As shown, the material box 2011 is slidably connected to the first mounting bracket 2051 in the middle of the mounting frame 205. The first mounting bracket 2051 is provided with a sliding rod 2016, and the material box 2011 has sliders 20112 on both sides, with the sliders 20112 fitted onto the corresponding sliding rods 2016. The solid material discharging mechanism 201 includes a material box driving device 2013, and the material box 2011 is connected to the power shaft of the material box driving device 2013 via a connecting element. The material box 2011 is driven to move left and right by the material box driving device 2013. The first mounting bracket 2051 in the middle of the mounting frame 205 is provided with a mounting plate 2012, and the material box driving device 2013 is mounted on the mounting plate 2012. A connecting plate 20111 is provided on one side of the material box 2011, and the connecting element is connected to the connecting plate 20111.

[0065] like Figures 8-9 As shown, in one embodiment of the present invention, the material box drive device 2013 is a material box motor, and the connecting element includes a crank 2014 and a connecting rod 2015, wherein one end of the crank 2014 is mounted on the output shaft of the material box motor, and the other end is hinged to the head end of the connecting rod 2015, and the tail end of the connecting rod 2015 is hinged to the connecting plate 20111 on one side of the material box 2011. The material box motor drives the crank 2014 to rotate, and the crank 2014 drives the material box 2011 to move left and right through the connecting rod 2015. The material box motor can be equipped with an encoder as needed to detect the speed of the motor in real time, and the control system calculates and controls the rotation angle of the crank 2014, thereby controlling the moving distance of the material box 2011 to adjust the number or area of ​​alignment between the material box outlet 2017 and the hopper outlet 2021. This is a well-known technology in the art. In addition, this embodiment is suitable for situations where the areas of the material box outlet 2017 and the hopper outlet 2021 are relatively small.

[0066] In another embodiment of the present invention, the material box driving device 2013 may be a linear driving device such as a cylinder, and one end of the power shaft of the linear driving device is connected to the head end of the connecting rod 2015 through a driving connecting rod set at a right angle. The tail end of the connecting rod 2015 is fixedly connected to the connecting plate 20111 on one side of the material box 2011. The mounting plate 2012 is provided with a guide groove, and the driving connecting rod passes through the guide groove. When the power shaft of the linear driving device moves telescopically, the connecting rod and the material box 2011 are driven to move left and right through the driving connecting rod. When moving, the driving connecting rod moves along the guide groove on the mounting plate 2012 to play a guiding role. In this embodiment, the telescopic amount of the power shaft of the linear driving device can be directly controlled by the control system to adjust the number or area of ​​alignment between the material box outlet 2017 and the hopper outlet 2021. This embodiment is suitable for cases where the areas of the material box outlet 2017 and the hopper outlet 2021 are relatively large.

Figure 14 As shown, when the roller pressure plate 3013 falls, it presses and fixes the roller shaft 30111 at the corresponding end of the film roller 3011. At this time, the roller locking bolt 3014 is threadedly connected to the film roller bracket 3012, locking the roller pressure plate 3013. After the film on the film roller 3011 is released, as... Figure 15 As shown, after the operator loosens the roller locking bolt 3014 outward, the roller shaft pressure plate 3013 can be lifted, and then the operator can replace the new film roller 3011.

Figures 13-14 As shown, the roller pressure plate 3013 is provided with a limiting block 30131, and the limiting block 30131 is provided with a limiting bolt 30132. When the roller pressure plate 3013 presses down on the roller shaft 30111 at the end of the film roller 3011, the operator can screw the limiting bolt 30132 so that its lower end abuts against the roller shaft 30111, thereby ensuring that the film roller 3011 will not move vertically. Figures 13-14 As shown, the film roller assembly 301 also includes guide rods 3015, and the two ends of the guide rods 3015 are respectively connected to the film roller brackets 3012 on the corresponding sides.

A film cutting nut is mounted on the film cutting screw 3033 on the film cutting slide 3032. The film cutting blade 3031 is mounted on the film cutting slide 3032. Rotation of the film cutting screw 3033 drives the film cutting slide 3032 to move, thereby driving the film cutting blade 3031 to move. Additionally, as shown...

[0073] like Figures 11-12As shown, the film stretching assembly 304 includes a film stretching motor, a film stretching screw 3042, and a film stretching slide 3043. Both the film stretching motor and the film stretching screw 3042 are mounted on the main frame 7. The film stretching screw 3042 is driven to rotate by the film stretching motor. A film stretching nut is mounted on the film stretching screw 3042 on the film stretching slide 3043. A film stretching clamp cylinder 3041 is mounted on the film stretching slide 3043. Rotation of the film stretching screw 3042 drives the film stretching slide 3043 to move, which in turn drives the film stretching clamp cylinder 3041 to move. The film stretching clamp cylinder 3041 is a double-output shaft gripper cylinder, a commercially available product, such as a MISUMI brand gripper cylinder. This invention employs a lead screw and nut structure to drive the film-pulling clamp cylinder 3041 to move. This allows for precise control of the film head's movement distance, ensuring that the film area covering the opening of the culture medium basin 8 meets the requirements. Furthermore, the movement distance can be flexibly adjusted according to the different volume specifications of the culture medium basins 8, thus flexibly adjusting the film-covering area. Additionally, the film-cutting blade 3031 and the film-pressing plate 3022 also possess sufficient lateral movement distance and pressing length to meet the film-covering needs of culture medium basins 8 of different specifications.

[0074] like Figures 17-19 As shown, the robotic arm of the film-fixing mechanism 4 includes a lifting plate 403, and two longitudinal cylinders 404 and two longitudinal moving seats 405 are symmetrically arranged on the lower side of the lifting plate 403. The longitudinal moving seats 405 are driven to move by the corresponding longitudinal cylinders 404. Two transverse cylinders 406 are symmetrically arranged on the lower side of the longitudinal moving seats 405, and a movable leather sleeve support rod 407 is provided on the lower side of the transverse cylinders 406. Additionally, as shown... Figures 26-27 As shown, the film-coating and fixing mechanism 4 also includes a baffle assembly 9. The culture medium basin 8 is transmitted to the film-coating and fixing station in the main frame 7 through the transmission line 6. The film-coating and fixing station is provided with baffle assemblies 9 on both sides. The baffle assembly 9 includes a retractable leather baffle 901.

[0075] like Figures 17-19 As shown, the robotic arm includes a movable plate 402 and a lifting cylinder 401. The movable plate 402 is mounted on the main frame 7, and the lifting cylinder 401 is mounted on the movable plate 402. The lifting plate 403 is located below the movable plate 402 and is fixedly connected to the power shaft end of the lifting cylinder 401. The lifting plate 403 is driven to rise and fall by the lifting cylinder 401, thereby driving the lower leather support rods 407 to rise and fall synchronously. Figure 17As shown, the movable plate 402 is slidably connected to the main frame 7, and the main frame 7 is provided with a drive screw 409. The movable plate 402 is provided with a movable block 408, and a drive nut is fitted inside the movable block 408 onto the drive screw 409. The drive screw 409 is driven to rotate by a movable motor, thereby driving the movable plate 402 to move on the main frame 7 via the movable block 408. In this embodiment, the main frame 7 is provided with a sliding rail, and the upper sides of both ends of the movable plate 402 are provided with sliding sliders that cooperate with the corresponding sliding rails to achieve a sliding connection with the main frame 7. Figures 18-19 As shown, the lower sides of both ends of the movable plate 402 are provided with lifting guide rods 4021, and the two ends of the lifting plate 403 are respectively provided with lifting through holes for the corresponding lifting guide rods 4021 to pass through.

[0076] like Figure 19 As shown, in this embodiment, the lower side of the lifting plate 403 is provided with a longitudinal slide rail 4031, and the upper end of the longitudinal moving seat 405 is provided with a longitudinal slider that cooperates with the longitudinal slide rail 4031 on the corresponding side to achieve a sliding connection with the lifting plate 403. The power shaft end of the longitudinal cylinder 404 is fixedly connected to the corresponding longitudinal moving seat 405. The transverse cylinder 406 is a rodless cylinder, and the upper end of the leather sleeve support rod 407 is installed on the moving slider of the corresponding rodless cylinder. The rodless cylinder is a commercially available product, such as a rodless cylinder from the MISUMI brand.

[0077] like Figures 26-27 As shown, the baffle assembly 9 includes a lateral moving device 902 and a lifting device 903. The lifting device 903 can be mounted on the frame on both sides of the transmission line 6, the lateral moving device 902 is mounted on the lifting device 903, and the leather baffle 901 is mounted on the lateral moving device 902. This allows the present invention to flexibly adjust the position of the leather baffle 901 according to the volume and height of the culture medium basin 8. The lateral moving device 902 can be a rodless cylinder, and the leather baffle 901 is fixedly connected to the sliding block on the rodless cylinder. 903 can employ linear drive devices such as cylinders, hydraulic cylinders, and electric push rods, and the lateral movement device 902 is mounted on the power shaft of the linear drive device. The lifting device 903 can adjust the height of the leather sleeve baffle 901 according to the different heights of the culture medium basins 8. In addition to driving the extension and retraction of the leather sleeve baffle 901, the lateral movement device 902 can also adjust the position of the extension blocking leather sleeve 504 of the leather sleeve baffle 901 according to the opening diameter of the culture medium basins 8 of different volumes. This further improves the flexibility and applicability of the present invention.

[0078] like Figures 20-25As shown, the leather sleeve screening mechanism 5 includes a bracket 503, a screw drive motor 501, a transmission assembly 505, and screws 502. Multiple screws 502 are rotatably mounted on the bracket 503, and each screw 502 has a helical protrusion 5026. A leather sleeve 504 is fitted onto the helical protrusions 5026 of each screw 502, and the leather sleeve 504 is stretched and tightened by the screws 502. Each screw 502 is driven to rotate synchronously by the screw drive motor 501, and the screw drive motor 501 transmits torque through the transmission assembly 505 located on the lower side of the bracket 503. The upper end of each screw 502 has a slot 5021. During operation, the leather sleeve 504 is stretched and driven to rise by the screws 502. Once the leather sleeve 504 has risen to its designated position, as... Figure 21 As shown, the uppermost leather sleeve 504 elastically contracts and is inserted into the slot 5021. Then, each screw 502 rotates in opposite directions to drive the remaining leather sleeves 504 to descend so as to leave a sufficient distance between them and the uppermost leather sleeve 504. Then, the leather sleeve support rod 407 at the lower end of the robotic arm of the film-fixing mechanism 4 is inserted into the uppermost leather sleeve 504 and opens up so that the uppermost leather sleeve 504 is opened and disengaged from the slot 5021 to complete the leather sleeve removal operation.

[0079] like Figure 21 As shown, in this embodiment, a pressure sensor 5022 is provided at the upper end of the screw 502, and the trigger end of the pressure sensor 5022 is connected to the upper end of the screw 502. This forms a groove 5021 between the lower surface of the pressure sensor 5022 and the upper surface of the screw 502. When the uppermost sheath 504 elastically retracts into the groove 5021, the pressure sensor 5022 is triggered, meaning the trigger end of the pressure sensor 5022 senses a pressure change. At this time, the pressure sensor 5022 sends a signal to the control system, and the control system automatically controls the screw drive motor 501 to reverse. The pressure sensor 5022 is a commercially available product, such as an Omron brand pressure sensor.

[0080] like Figures 21-24 As shown, in this embodiment, the transmission assembly 505 includes a synchronous belt 5051 and multiple tension pulleys. The motor shaft of the screw drive motor 501 is provided with a drive pulley 5011. Each screw 502 has a screw pulley at its lower end. The synchronous belt 5051 passes around each tension pulley, each screw pulley, and the drive pulley 5011. As shown... Figure 24As shown, a first tensioning pulley 5052 is provided on the side of the first screw pulley 5024 near the drive pulley 5011, and a second tensioning pulley 5053 is provided on the other side. The synchronous belt 5051, passing over the drive pulley 5011, the first screw pulley 5024, the first tensioning pulley 5052, and the second tensioning pulley 5053, forms a cross shape. A third tensioning pulley 5054 is provided on the side of the second screw pulley 5025 away from the drive pulley 5011, and the synchronous belt 5051, passing over the third tensioning pulley 5054 and the second screw pulley 5025, forms a T-shape. Additionally, a screw seat 5023 is provided on the bracket 503, and the lower end of the screw 502 is rotatably mounted in the corresponding screw seat 5023 via a bearing.

[0081] The working principle of this invention is as follows:

[0082] In operation, this invention utilizes a separate container mechanism 1 to separate the stacked culture medium containers 8 one by one and transfer them to the conveyor line 6, specifically as follows: Figures 2-6 As shown, stacked culture medium basins 8 are placed on an inclined basin stand 101 and gradually move downwards under gravity. A basin-separating assembly 103 is mounted on a basin-separating assembly mounting plate 102 at the output end of the basin stand 101. The opening edge of the basin-separating assembly mounting plate 102 is provided with a limiting plate 1021 to ensure that only basins of the required size can pass through. Appropriate detection sensors can be installed on the limiting plate 1021 as needed. During the basin-separating operation, each transmission plate 1034 of the basin-separating assembly 103 is initially in position... Figure 4 As shown, the second blade 1035 is positioned below the opening edge of the lowest culture medium container 8 to be separated, while each of the first blades 1033 is positioned on the outer circumference of the lowest culture medium container 8 to be separated without obstruction. Then, the separating cylinder 1031 drives each of the first blades 1033 to rotate to the position indicated. Figure 5 At the indicated position, the first blade 1033 rotates inward and uses the end of the blade body 10332 to separate the edge of the bottommost culture medium container 8 from the edges of other containers. Simultaneously, the blade body 10332 of the first blade 1033 also blocks the edge of the next container, preventing it from falling. Meanwhile, each of the second blades 1035 rotates outward to a position where it no longer obstructs the movement of the bottommost culture medium container 8. Additionally, as shown... Figure 2 and Figure 6As shown, the suction cup drive cylinder 1051 in the suction cup assembly 105 extends before the separation and drives the rotating connecting plate 1052 to rotate, thereby causing each suction cup 1053 to enter the bottommost culture medium basin 8 to be separated. After the bottommost culture medium basin 8 is initially separated from other basins by the separation assembly 103, each suction cup 1053 adsorbs the bottommost culture medium basin 8. Then, the suction cup drive cylinder 1051 retracts and drives the rotating connecting plate 1052 to rotate, thereby driving the suction cup 1053 to swing and take out the bottommost culture medium basin 8 and place it on the transmission line 6. Then, it is sent to the raw material injection mechanism 2 through the transmission line 6 to inject solid materials (grains) and liquid materials (culture solution).

[0083] like Figures 7-10 When the raw material feeding mechanism 2 is working, the left and right movement of the material box 2011 can change the number or area of ​​alignment between its material box outlet 2017 and the hopper outlet 2021 at the lower end of the solid hopper 202, thereby changing the discharge flow rate of the solid material to achieve the purpose of adjustment. When the material box outlet 2017 and the hopper outlet 2021 are completely misaligned, the remaining part of the material box 2011 blocks the hopper outlet 2021, and the solid material cannot be discharged and fall, thus realizing the solid material discharge shut-off function. Each liquid material pipe is equipped with a flow control valve to control the output flow rate of the liquid material. In this way, the present invention achieves the purpose of accurately controlling the proportion of culture medium materials by controlling the adjustment of the solid material discharge flow rate and the liquid material output flow rate through the control system. In addition, the material box driving device 103 that drives the left and right movement of the material box 2011 can be selected according to actual needs, and the connecting elements connecting the material box 2011 and the material box driving device 103 can also be selected with different structural forms.

[0084] like Figures 7-10The raw material feeding mechanism 2 of the present invention includes two liquid feed pipes, and the first liquid outlet 2041 on the first liquid feed pipe 204 and the second liquid outlet 2031 on the second liquid feed pipe 203 are approximately 90° apart in the feeding direction. This allows the mixed material to flow to a certain extent, thereby playing an auxiliary mixing and stirring role. The first liquid outlet 2041 is set facing the input direction of the culture medium basin 8 and injects liquid material into the basin after the culture medium basin 8 is in place, while the second liquid outlet 2031 is turned to inject liquid material towards the culture medium basin. Furthermore, the first liquid outlet 2041 and the second liquid outlet 2031 can also be injected with the same or different materials as needed. For example, the first liquid outlet 2041 can be injected with culture medium, and the second liquid outlet 2031 can be injected with water. This allows control of the flow rates of the two injected liquid materials to ensure that the concentration of the culture medium meets the requirements. Alternatively, the first liquid outlet 2041 and the second liquid outlet 2031 can be injected with culture mediums of different compositions to meet the requirements for preparing culture media for different edible and medicinal fungi. In addition, when the volume of the culture medium container is relatively small, the present invention can also rely solely on the first liquid outlet 2041 to inject liquid materials, in which case the second liquid outlet 2031 is closed and... Figure 8 Turn it to the position where the output port faces downwards.

[0085] After the culture medium tray 8 is filled by the raw material filling mechanism 2, it is then conveyed by the conveyor line 6 to the film covering mechanism 3 to complete the opening covering film operation. Specifically, at the beginning of operation, the culture medium tray 8 is transported by the conveyor line 6 to the film covering station below the film pressing assembly 302. Then, the film is drawn out from the film roller 3011 and covers the upper opening of the culture medium tray 8. At the same time, the film head is clamped and fixed by the upper clamping plate 30411 and the lower clamping plate 3041 of the film pulling clamping cylinder 3041. Then, the conveyor line 6 is started to drive the culture medium tray 8 to move out of the film covering station. The film-pulling clamp cylinder 3041 moves synchronously with the transmission line 6 to pull out the film. This ensures that when the culture medium basin moves to the next set station, its upper opening remains covered by the film. Furthermore, during the movement of the culture medium basin 8, the film pressing plate 3022 in the film-pressing assembly 302 is in a lowered state. This allows the film at the upper end of the culture medium basin 8 to be completely covered by the pressing action of the film pressing plate 3022. Meanwhile, the film cutting blade 3031 in the film-cutting assembly 303 moves to one side of the transmission line 6, thus not affecting the movement of the culture medium basin and the film. Once the culture medium basin is in position, as... Figure 16As shown, at this time, the film cutting blade 3031 can move laterally in the left and right direction to cut and separate the film covering the material basin from the subsequent film. Then, the film cutting blade 3031 moves back to one side of the transmission line 6, and the upper clamping plate 30411 and lower clamping plate 3041 of the film clamping cylinder 3041 open and return to their original positions. At this time, the culture medium basin 8 that has completed film covering is driven into the film covering and fixing station in the main frame body 7 through the transmission line 6 to complete the film covering and fixing process. At the same time, the next culture medium basin 8 re-enters the film covering station and supports the head end of the new film formed after film cutting. Figure 12 As shown, one end of the film-pulling clamp cylinder 3041 retracts past the film-cutting assembly 303, so that the upper clamping plate 30411 and the lower clamping plate 30412 of the film-pulling clamp cylinder 3041 can clamp the new film head again and repeat the above process. That is, the transmission line 6 starts to drive the culture medium basin 8 to enter the next station. At the same time, the film-pulling clamp cylinder 3041 moves to continue to pull out the film. When the basin and the film move, the film pressing plate 3022 in the film pressing assembly 302 descends to press the film tightly on the upper opening of the basin. When the culture medium basin 8 moves into place, the film cutting blade 3031 in the film cutting assembly 303 moves laterally again to cut the film.

[0086] Additionally, after the film on the film roller 3011 has been completely released, as Figures 14-15 As shown, after the operator loosens the locking bolt 3014 outward, the roller pressure plate 3013 can be lifted, and then the operator can replace the new film roller 3011. At the same time, this structure also makes it convenient to replace the film roll of appropriate width according to the different specifications of the culture medium basin 8.

[0087] After the culture medium tray 8 completes the opening and covering with film by the film covering mechanism 3, the film covering and fixing mechanism 4 then completes the fixing of the film cover 504. Specifically:

[0088] Firstly, as Figures 20-24 As shown, the sleeves 504 are uniformly fitted onto each screw 502 of the sleeve screening mechanism 5 to complete the screening and separation of a single sleeve 504. The sleeves 504 are fitted onto the spiral protrusions 5026 of each screw 502, and the sleeves 504 are stretched and tightened by each screw 502. When each screw 502 rotates synchronously, the spiral protrusions 5026 on each screw 502 also rotate. Because the sleeves 504 are stretched by the spiral protrusions 5026 on each screw 502, thus... Figure 21As shown, the portion of the sleeve 504 fitted onto the corresponding screw 502 moves along the spiral protrusion 5026 as the screw 502 rotates, thus achieving lifting and lowering. The upper end of the spiral protrusion 5026 engages with the slot 5021 at the upper end of the corresponding screw 502. When the sleeve rises to the upper end of the screw 502, the uppermost sleeve 504 disengages from the spiral protrusion 5026 and elastically retracts, locking onto the slots 5021 at the upper end of each screw 502, thus preventing further movement along the spiral protrusion 5026. Then, the screw drive motor 501 controls each screw 502 to move in the opposite direction, causing the remaining sleeves to descend. This creates sufficient distance between the sleeve 504 locked in the slot 5021 and the other sleeves.

[0089] Then, the robotic arm in the film-coating and fixing mechanism 4 moves to above the leather sleeve screening mechanism 5 via the moving plate 402 and removes the leather sleeve 504 stuck in the slot 5021. The robotic arm is equipped with multiple leather sleeve support rods 407, and each leather sleeve support rod 407 can be driven to open and close laterally (perpendicular to the transmission direction of the transmission line 6) by the corresponding transverse cylinder 406, and can also be driven to open and close longitudinally (parallel to the transmission direction of the transmission line 6) by the corresponding longitudinal moving seat 405. It can also be driven to lift synchronously by the lifting plate 403. When removing the leather sleeve 504, each leather sleeve support rod 407 first retracts horizontally. Then, the lifting plate 403 descends so that the retracted leather sleeve support rod 407 is inserted into the uppermost leather sleeve 504 that is stuck in the slot 5021. After the lifting plate 403 descends to the position, the lower ends of each leather sleeve support rod 407 are above the other leather sleeves. In this way, when each leather sleeve support rod 407 reopens, it can open the uppermost leather sleeve 504 to make it disengage from the slot 5021 and each screw 502, without affecting the other leather sleeves. Then, the lifting plate 403 rises and drives the lower end of the tightly supported leather sleeve 504 to rise and completely disengage from the leather sleeve screening mechanism 5. Finally, the robot arm is moved to the film-coating fixing station by the moving plate 402.

[0090] And such Figures 26-27 As shown, after the robotic arm moves the sleeve 504 to above the film-coating and fixing station, each sleeve support rod 407, together with the supported sleeve 504, first descends to allow the sleeve 504 to be fitted onto the outside of the culture medium basin 8 whose upper opening is already covered with film. Then, the sleeve baffles 901 in the baffle assemblies 9 on both sides of the transmission line 6 extend, and then each sleeve support rod 407 rises synchronously. At this time, due to the obstruction of the sleeve baffles 901, the sleeve 504 separates from the sleeve support rod 407 and automatically elastically retracts to cover and fix the edge of the film at the upper opening of the culture medium basin 8, thereby completing the film-coating and fixing operation.
