Specific Implementation

[0064] The automatic cleaning device for culture bottles is used in the enoki mushroom cultivation and production workshop. First, the device is installed in sequence according to the installation instructions. Ensure that the installation between each piece of equipment is firm and that the sealed parts are well sealed to prevent liquid leakage. Connect the cables of each piece of electrical equipment to the output terminal of the power supply unit 79, and connect each control line to the controller 80. Connect the input terminal of the power supply unit 79 to the mains power through the cable. Check the device again to ensure that there are no abnormalities. Turn on the LCD touch screen 81. The LCD touch screen 81 displays the operation interface of the device. According to the size, height and degree of dirt of the culture bottles, manually input the instructions for various control data. Place the culture bottles to be cleaned in batches on the conveyor belt I 60. Click the start button on the LCD touch screen 81, and all equipment enters the standby state.

[0065] The controller 80 instructs the mixing tank 39 to start working. The corresponding water pumps 34 draw cleaning agent from the external liquid supply equipment and clean water from the external water supply equipment into the mixing tank 39. Under the stirring of the agitator, the mixture is fully mixed. The liquid level sensor 43 detects the liquid level of the cleaning solution in the mixing tank 39 in real time. When the set maximum value is reached, the water pumps drawing cleaning agent and clean water stop working. At the same time, the concentration detector 44 detects the concentration change of the cleaning solution in real time and controls the water pumps 34 drawing cleaning agent and clean water to mix according to the preset concentration value. The controller 80 instructs the relevant water pumps 34 to draw cleaning solution into the heating box 30. The electric heating tube 32 heats the cleaning solution. The temperature sensor 31 detects the temperature of the cleaning solution in real time. When the set value is reached, the electric heating tube 32 stops heating. When the temperature is lower than the set value, the electric heating tube 32 continues heating.

[0066] Pressure sensor I64 on baffle 63 senses no pressure and transmits the data to controller 80. Controller 80 then instructs conveyor belt I60 to start operating. Guided by the V-shaped guide plate 62, only one culture bottle enters the rear port of guide plate 62 along the conveying direction, pressing against baffle 63. Pressure sensor I64 transmits the pressure value to controller 80 in real time. When the pressure value reaches the set value, controller 80 instructs conveyor belt I60 to stop operating. Simultaneously, controller 80 instructs chain conveyor 4 to rotate at a set speed. The robotic arm 61, following a preset stroke, uses its end gripper to pick up the culture bottle located at the rear port of guide plate 62. The drive unit then delivers the culture bottle to the center position of the chain conveyor 4's chain plate laterally. Pressure sensor I64 on baffle 63 senses no pressure again, and controller 80... The controller 80 instructs the conveyor belt I 60 to continue working, and the guide plate 62 guides the next culture bottle into the rear port of the guide plate 62 and squeezes the baffle 63. The conveyor belt I 60 stops working again. The displacement sensor 70 transmits the displacement change of the next circular groove 5 to the controller 80 in real time. When the circular groove 5 moves to the bottom of the culture bottle being gripped, the controller 80 instructs the robotic arm 61 to release the culture bottle into the circular groove 5. The robotic arm 61 immediately returns to the rear port of the guide plate 62 according to the preset stroke, grips the culture bottle and sends it to the center position of the chain plate of the chain conveyor 4 in the transverse direction. This cycle continues. The pressure sensor II 71 senses the change in pressure value in the circular groove 5 and works together with the displacement sensor 70 of the same circular groove 5 to transmit the displacement change to the controller 80 in real time.

[0067] When the first culture bottle is delivered to the pre-cleaning assembly 2, the controller 80 instructs the water pumps 34 of a preset number of spraying units 29 to continuously deliver high-pressure cleaning fluid at a set temperature to their respective annular array nozzles 33. The high-pressure cleaning fluid is sprayed from a preset number of nozzles 37 towards the inside and outside of the passing culture bottle, thoroughly soaking and softening the inside of the bottle and thoroughly cleaning the outside of the bottle. Due to the design of the honeycomb bottle pad 73, the high-pressure sprayed cleaning fluid can also thoroughly clean the bottom of the bottle. When the culture bottle leaves the pre-cleaning assembly 2, the controller 80 instructs the clamping unit 6 to clamp the culture bottle through the soft plastic on the side of the circular groove 5. The membrane pressure sensor II 74 detects the clamping pressure of the clamping unit 6 in real time. After reaching the set value, the controller 80 instructs to stop clamping. The chain plate of the chain conveyor 4 rotates 180° through the flipping part I 66, causing the culture bottle to be inverted. The cleaning fluid sprayed into the culture bottle by the pre-cleaning assembly 2 is poured out and flows into the collection tank 40 through the guide channel 76. The culture bottle enters the inverting part 67.

[0068] Because the conveying speeds of the chain conveyor 4 and the racetrack conveyor I 27 are the same, the distance between two adjacent sealing brushing assemblies 1 is equal to the distance between two adjacent circular grooves 5. When the inverted culture bottle moves directly above the sealing brushing assembly 1, the controller 80 instructs the sealing brushing assembly 1 to move upwards while the racetrack conveyor I 27 and the chain conveyor 4 rotate in the same direction and at the same speed. The bottle mouth sealing unit 9 seals the bottle mouth. The membrane pressure sensor I 12 detects the pressure between the conical sealing cap 11 and the bottle mouth in real time. When the preset pressure value is reached, the controller 80 instructs the sealing brushing assembly 1 to stop moving upwards and pressing, reducing the breakage rate of the bottle mouth and effectively... To save on cleaning fluid usage, the brushing unit 10 extends into the culture bottle. Simultaneously, the controller 80 instructs the relevant water pump 34 to draw cleaning fluid from the mixing tank 39 and spray an appropriate amount of cleaning fluid into the culture bottle through the supply hole 15 before stopping the spraying. The controller 80 instructs the brushing unit 10 to rotate. Due to the design of the segmented brush rollers 22 at the front, middle, and rear ends, the bottom, body, and mouth of the culture bottle are brushed in segments to remove debris from the dead corners inside the bottle. The culture bottle moves to the end of the sealing brushing assembly 1, and the controller 80 instructs the sealing brushing assembly 1 to move down to the initial state and stop brushing. The cleaning fluid in the culture bottle flows out and flows into the collection tank 40 through the guide channel 76.

[0069] The inverted culture bottle enters the rinsing assembly 46. Since the conveying speeds of the chain conveyor 4 and the racetrack conveyor II 52 are the same, the distance between two adjacent inner wall spray units 47 is equal to the distance between two adjacent circular grooves 5. When the inverted culture bottle moves directly above the inner wall spray unit 47, the controller 80 instructs the inner wall spray unit 47 to move upward while the racetrack conveyor II 52 and the chain conveyor 4 rotate in the same direction and at the same speed. At the same time, the relevant water pump 34 draws clean water from the external water supply equipment. The spray pipe 51 extends into the culture bottle and sprays high-pressure water onto the bottom, body and mouth of the culture bottle for rinsing. A preset number of outer wall spray units 48 continuously spray high-pressure water onto the outer wall of the passing culture bottle for rinsing. When the culture bottle moves to the end of the rinsing assembly 46, the controller 80 instructs the inner wall spray unit 47 to move downward to the initial state and stops spraying. The cleaning solution used for rinsing flows into the collection tank 40 through the guide channel 76.

[0070] The inverted culture flasks leave the rinsing assembly 46 and enter the heat pump drying and dehumidifying unit 55 through the inlet 57, with the hanging parts of the elastic curtain 56 blocked by the culture flasks. After the culture flasks enter, the hanging parts of the elastic curtain 56 automatically return to their initial position. The controller 80 instructs the heat pump drying and dehumidifying unit 55 to continuously dry the culture flasks at the set temperature. The internal moisture is discharged by the dehumidifier. After drying, the culture flasks leave the drying assembly 54 through the outlet 58, with the hanging parts of the elastic curtain 56 blocked by the culture flasks.

[0071] The chain plate of the chain conveyor 4 rotates 180° through the flipping part II68 to turn the culture bottle upright. After cleaning and drying, the culture bottle enters the upright part II69. The controller 80 instructs the clamping unit 6 to release the culture bottle and transport it to the conveyor belt II72. The conveyor belt II72 then transports the culture bottle to the external bottle storage equipment, thus completing the entire bottle washing and drying process.

[0072] The cleaning fluid used by the pre-cleaning component 2, the sealing brushing component 1, and the rinsing component 46 flows into the collection tank 40 through the guide channel 76. The used cleaning fluid is then filtered through a three-stage filter 41 for coarse filtration, fine filtration, and precision purification from the outlet of the collection tank 40, which effectively removes impurities from the cleaning fluid. The fluid is then recycled through a hose from the recovery port of the liquid collection tank 39, thus saving costs efficiently.

[0073] The pre-cleaning component 2, the sealing brushing component 1, the rinsing component 46, and the drying component 54 are all set to preset lengths to ensure that the pre-cleaning, brushing, rinsing, and drying times of the culture flasks all meet the predetermined requirements.

[0074] The power distribution control box 77 provides mains power to all electrical equipment in the device. The controller 80 has a modular programming logic function and can control the operation of related equipment according to the data detected by various sensors and the set values. All moving electrical equipment uses the sliding contact line power supply method.
