Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and in particular to a filling equipment and a filling method for plant preparation production. Background Art

[0002] During the production of existing plant adjustment agents, it is necessary to fill the plant adjustment agents into specific containers to complete the packaging of the finished product of the plant adjustment agents. The existing filling is mainly divided into normal pressure filling, negative pressure filling, isobaric filling and other filling methods. Among them, the more commonly used is the normal pressure filling method. Normal pressure filling is also called dead weight filling or liquid level controlled quantitative filling. It is a filling method in which liquid relies on its own weight to flow from a liquid storage tank or a metering cylinder into a container. The existing normal pressure filling equipment is mainly composed of a liquid storage tank, a spring, a sliding sleeve, a filling valve, a butterfly valve and an exhaust pipe. When the container rises and hits the filling valve and compresses the spring, the bottle mouth is sealed. At this time, the butterfly valve opens the valve, allowing the liquid in the liquid storage tank to automatically flow into the container along the outer wall of the exhaust pipe and the gap around the butterfly valve, thereby achieving filling. During filling, the gas inside the container is discharged from the exhaust pipe until the inside of the container is filled, then the butterfly valve closes, and the liquid no longer flows into the container, thereby completing the final filling work.

[0003] When existing filling equipment is filling a container, the liquid falls due to its own gravity. When the butterfly valve is opened, the released liquid has a large impact, and the liquid will hit the bottom of the container vigorously. Since the interior of the container is rigid, if the container is not hard and is relatively fragile, the bottom of the container is likely to break or deform during filling, resulting in filling failure and even leakage of the plant adjustment agent. Summary of the Invention

[0004] The present application proposes a filling device and a filling method for plant adjustment production, which have the advantages of autonomously adjusting the liquid discharge rate, preventing the liquid filling force from being too large, ensuring the effective and safe filling, and effectively preventing the accumulation of liquid at the liquid outlet after filling, thereby causing secondary pollution. It is used to solve the problem that the existing filling force is too large, and after the filling is completed, a small amount of liquid will accumulate at the liquid outlet, which will cause secondary filling pollution.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions: a filling device for plant adjustment production, comprising a filling head: a filling valve is fixedly installed in the middle of the filling head, a butterfly valve is fixedly installed in the middle of the inner cavity of the filling valve, an air outlet pipe is fixedly installed in the middle of the butterfly valve, a positioning conductive block is movably installed at the bottom of the filling head, a resistor block is fixedly installed inside the filling head, and the resistor block is located above the top of the positioning conductive block, a fixed support plate is fixedly installed on the outer side of the bottom of the filling valve, and a movable electromagnet is movably installed at the bottom of the inner cavity of the fixed support plate. A first spring is fixedly installed on one side surface of the electromagnet, a first magnetic block is fixedly installed on one end of the first spring, and one side surface of the first magnetic block is fixedly installed on the inner cavity side wall of the fixed support plate, a speed regulating plate is fixedly installed on the bottom end of the movable electromagnet, a second magnetic block is slidably installed on one side of the inner cavity of the speed regulating plate, and absorbent cotton is slidably installed on the other side of the inner cavity of the speed regulating plate, the absorbent cotton is fixedly connected to the second magnetic block by a traction rope, a drainage sealing membrane is fixedly installed on the top of the inner wall of the speed regulating plate, and the other end of the drainage sealing membrane is fixedly connected to the bottom inner wall of the filling valve.

[0006] Furthermore, a container bottle is movably mounted on the bottom end of the filling head, a movable plate is movably mounted on the bottom end of the container bottle, a second spring is fixedly mounted on the bottom end of the movable plate, and a conveying platform is fixedly mounted on the bottom end of the second spring.

[0007] Furthermore, the positioning conductive block is in the shape of a "concave" character, and the top of the positioning conductive block is conductive. The bottom of the filling head is provided with a slide groove adapted to the structure of the positioning conductive block. The overall shape of the resistor block is adapted to the internal depression of the positioning conductive block. The resistor block is divided into two parts, the upper part of the resistor block has a resistance value smaller than the resistance value of the lower part of the resistor block. One end of the resistor block is fixedly connected to one end of the movable electromagnet through an electrical wire, and one end of the positioning conductive block is fixedly connected to the power supply of the existing equipment through an electrical wire.

[0008] Furthermore, the fixed support plate is in the shape of a circular ring, and the interior of the fixed support plate is hollow. A slide groove that matches the shape of the movable electromagnet is provided on the bottom surface of the fixed support plate. There are four movable electromagnets in total, and the movable electromagnets are evenly distributed in a circular shape at the bottom of the fixed support plate. The magnetism displayed by the movable electromagnet after power is applied is repelled by the magnetism of the first magnetic block, and attracted by the magnetism of the second magnetic block.

[0009] Furthermore, both the first magnetic block and the second magnetic block are magnetic. There are four speed regulating plates in total, and the speed regulating plates are evenly distributed in a circular shape below the bottom end of the filling valve. The shape of the speed regulating plate is "L"-shaped, and the interior of the speed regulating plate is hollow. The vertical section of the speed regulating plate is rectangular, and the horizontal section is an isosceles trapezoid. The thickness of the upper surface of the horizontal section of the speed regulating plate increases from the inside to the outside.

[0010] Furthermore, there are four absorbent cottons in total, and the absorbent cottons are evenly distributed in a circular shape below the bottom end of the filling valve and are adapted to the position of the speed regulating plate. The absorbent cottons are triangular in shape and are elastic and absorbent.

[0011] A filling method for a filling device for plant preparation production comprises the following steps:

[0012] S1. When performing plant adjustment and filling, first, the container bottles are evenly arranged on the top of the conveyor table, and the bottom end of each container bottle is directly opposite the top end of the movable plate. Because the elastic force of the second spring is adapted to the gravity of the empty container bottle, when the container bottle is placed, the top surface of the movable plate is flush with the top surface of the conveyor table. Through the existing transmission equipment, the conveyor table is continuously moved forward in a cycle, thereby driving the container bottles on its surface to move forward;

[0013] S2. When the container bottle moves to the position directly below the filling head, the existing control system controls the filling head to move downward. At the same time, the conveyor is also controlled to move upward to transport the container bottle upward and dock with the bottom end of the filling head. When the bottom end of the filling head and the top end of the container bottle are completely against each other, the existing control system controls the butterfly valve to open the valve, thereby starting filling. At the same time, when the filling head and the container bottle are in contact, the positioning conductive block is squeezed by the container bottle and moves upward, so that the positioning conductive block is completely in contact with the resistor block. The positioning conductive block completely wraps the resistor block, and the top of the positioning conductive block is in contact with the upper part of the resistor block, so that the current in the external existing equipment power supply passes through the positioning conductive block. The conductive block, then passes through the resistor block and is finally conducted to the movable electromagnet. Since the resistance value of the upper part of the resistor block is small, the amount of electricity flowing through the movable electromagnet is large, and thus the magnetism displayed by the movable electromagnet is strong, and the magnetic repulsion of the movable electromagnet to the first magnetic block is also large. Since the position of the first magnetic block is fixed, the movable electromagnet moves outward under the action of the magnetic repulsion, and the movable electromagnet moves outward a large distance. In this way, the volume of the cavity formed between the speed regulating plates is large. When the butterfly valve opens the valve, the plant adjustment passes through the liquid filling valve lumen and flows to the speed regulating plate. The flow rate of the plant adjustment is slow. Then, when the plant adjustment flows out of the speed regulating plate and then flows into the container bottle, the plant adjustment has a small impact on the liquid at the bottom of the container bottle, thereby avoiding damage to the bottom of the container bottle.

[0014] S3. After a period of filling, a certain amount of plant adjustment agent has accumulated at the bottom of the container bottle. Due to the gravity of the plant adjustment agent, the downward pressure of the container bottle on the movable plate increases, causing the movable plate to squeeze the second spring downward. The elastic force of the second spring itself is less than the existing downward pressure, and then the movable plate moves downward, and the container bottle also moves downward. When the container bottle moves downward, the top of the container bottle is separated from the filling head for a distance, and the positioning conductive block moves downward and partially separates from the resistor block. Then the top of the positioning conductive block touches the lower part of the resistor block and is energized. The resistance value of the lower part of the block is larger, then the amount of current flowing through the movable electromagnet becomes smaller, and the magnetic repulsion of the movable electromagnet on the first magnetic block becomes smaller, and the movable electromagnet moves back inward again, but because the magnetic repulsion is still there, the movable electromagnet will not completely reset in the opposite direction. However, the cavity formed between the speed regulating plates will be affected by the reverse reset of the movable electromagnet and its volume will be reduced. At this time, the flow rate of the plant adjustment agent begins to increase, and then the filling speed also becomes faster. The plant adjustment agent liquid layer accumulated at the bottom of the container bottle is used to buffer the newly poured liquid, avoiding the large impact directly hitting the bottom of the container bottle.

[0015] S4. When the container bottle is filled with the planting agent, that is, the filling is completed, at this time, the conveyor moves downward, and the container bottle moves downward significantly, the container bottle is completely separated from the filling head, and then the positioning conductive block also completely falls to the initial position. After the positioning conductive block is completely separated from the resistance block, the power is cut off at the movable electromagnet, and the magnetic repulsion of the movable electromagnet on the first magnetic block disappears. Under the elastic force of the first spring, the movable electromagnet is completely reset inward and returned to the initial position. At the same time, the speed regulating plate moves inward and shrinks and resets together with the movable electromagnet. When the speed regulating plate is completely reset, the four absorbent cottons are relatively closed to form a seal. At this time, the suspended droplets accumulated on the speed regulating plate, the filling valve and the outlet pipe opening all drip onto the surface of the absorbent cotton and are absorbed by the absorbent cotton. When a new empty bottle moves to the bottom of the filling head, a new round of filling work begins. As can be seen from the above steps, the speed regulating plate moves outward with the movable electromagnet. At this time, the movable electromagnet generates a magnetic attraction on the second magnetic block, causing the second magnetic block to move upward. When the second magnetic block moves upward, the second magnetic block drives the absorbent cotton to move outward through the traction rope. Since the thickness of the upper surface of the horizontal section of the speed regulating plate increases from the inside to the outside, when the absorbent cotton moves outward, the speed regulating plate squeezes the surface of the absorbent cotton, and then squeezes out the liquid absorbed by the absorbent cotton, so that the liquid flows into the interior of the container bottle together with the new filling liquid until the interior of the container bottle is filled with the adjusting agent. Therefore, the cyclic filling can be completed by repeating the above steps.

[0016] The present application provides a filling device for the production of plant preparations. By providing a positioning conductive block, a resistor block, a movable electromagnet, and a speed regulating plate, the device achieves that in the initial filling stage, when the plant preparation flows out of the speed regulating plate, the flow rate is relatively slow and the liquid impact is small, thereby avoiding significant damage to the bottom of the container bottle. In the middle and late stages of filling, the plant preparation flows out of the speed regulating plate at a faster rate, thereby improving the filling efficiency. The liquid layer accumulated at the bottom of the container bottle in the initial stage is used to buffer the liquid impact, thereby ensuring that the bottom of the container bottle can always be buffered by the impact while ensuring a constant filling efficiency.

[0017] In addition, by setting up a speed regulating plate and liquid-absorbing cotton, it is possible to prevent the accumulated liquid from dripping to the outside at the end of filling, causing equipment pollution. When filling again, the recovered accumulated liquid can be reused and refilled into the next container bottle, thereby improving the utilization rate of the plant regulator, avoiding waste of plant regulator filling, and improving the filling efficiency.

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] Example 1

[0026] See also Figures 1-4A filling device for plant adjustment production includes a filling head 1, a filling valve 2 is fixedly installed in the middle of the filling head 1, a butterfly valve 3 is fixedly installed in the middle of the inner cavity of the filling valve 2, an air outlet pipe 4 is fixedly installed in the middle of the butterfly valve 3, a positioning conductive block 5 is movably installed at the bottom of the filling head 1, a resistor block 6 is fixedly installed inside the filling head 1, and the resistor block 6 is located above the top of the positioning conductive block 5, a fixed support plate 7 is fixedly installed on the outside of the bottom of the filling valve 2, a movable electromagnet 8 is movably installed on the bottom of the inner cavity of the fixed support plate 7, a first spring 9 is fixedly installed on one side surface of the movable electromagnet 8, a first magnetic block 10 is fixedly installed on one end of the first spring 9, and one side surface of the first magnetic block 10 is fixedly installed on the side wall of the inner cavity of the fixed support plate 7, and the movable electromagnet 8 is fixedly installed on the inner cavity side wall of the fixed support plate 7. A speed regulating plate 11 is fixedly installed at the bottom end, and a second magnetic block 12 is slidably installed on one side of the inner cavity of the speed regulating plate 11, and a liquid-absorbing cotton 13 is slidably installed on the other side of the inner cavity of the speed regulating plate 11. The liquid-absorbing cotton 13 is fixedly connected to the second magnetic block 12 through a traction rope 14. A drainage sealing membrane 15 is fixedly installed on the top of the inner wall of the speed regulating plate 11, and the other end of the drainage sealing membrane 15 is fixedly connected to the bottom inner wall of the filling valve 2. The drainage sealing membrane 15 is shaped like a "Z" and has elasticity. By arranging the positioning conductive block 5, the resistance block 6, the movable electromagnet 8 and the speed regulating plate 11 and other structures, when the plant adjustment filling is carried out, the container bottle 16 moves upward to squeeze the positioning conductive block 5, so that the positioning conductive block 5 moves upward. When the container bottle 16 is completely aligned with the filling head 1 When they are attached and sealed, the positioning conductive block 5 completely wraps the resistor block 6 tightly, so that the top of the positioning conductive block 5 touches the upper part of the resistor block 6 and conducts electricity. Since the resistance value of the upper part of the resistor block 6 is small, a large amount of current can pass through, and the current value transmitted to the movable electromagnet 8 through the positioning conductive block 5 and the resistor block 6 is large, so that the magnetism displayed by the movable electromagnet 8 is strong, and the magnetic repulsion of the movable electromagnet 8 on the first magnetic block 10 is large. Since the position of the first magnetic block 10 is fixed, the movable electromagnet 8 moves outward under the action of the magnetic repulsion. When the movable electromagnet 8 moves outward, the movable electromagnet 8 drives the speed regulating plate 11 to move outward together. Since the magnetic repulsion is large, the movable electromagnet 8 moves outward a large distance, and the cavity formed between the speed regulating plates 11 has a larger capacity. The volume is also large, and the volume formed by the speed regulating plate 11 will definitely be larger than the opening volume at the bottom of the filling valve 2. Then, when the butterfly valve 3 opens the valve and allows the plant adjustment to fall naturally, due to the guiding effect of the drainage sealing membrane 15 on the plant adjustment, the plant adjustment flows in the area where the speed regulating plate 11 is located, and the flow rate is relatively slow. Then, when the plant adjustment flows out of the speed regulating plate 11 and then flows into the container bottle 16, the outlet flow rate is low, and the liquid impact on the bottom of the container bottle 16 is small, thereby avoiding damage to the bottom of the container bottle 16. When a certain amount of plant adjustment accumulates at the bottom of the container bottle 16, due to the gravity of the plant adjustment, the downward pressure of the container bottle 16 on the movable plate 17 becomes greater, and the movable plate 17 squeezes the second spring 18 downward, causing the container bottle 16 to move downward. When the container bottle 16 moves downward,When the top of the container bottle 16 is separated from the filling head 1 by a certain distance, the positioning conductive block 5 moves downward and partially separates from the resistance block 6, and then the top of the positioning conductive block 5 touches the lower part of the resistance block 6 to be energized. Since the resistance value of the lower part of the resistance block 6 is large, the current transmitted through the positioning conductive block 5 and the resistance block 6 to the movable electromagnet 8 becomes smaller, and the magnetic repulsion of the movable electromagnet 8 on the first magnetic block 10 becomes smaller. The movable electromagnet 8 moves back inward again, but because the magnetic repulsion still exists, a certain distance is still retained between the movable electromagnet 8 and the first magnetic block 10, but compared with the magnetic repulsion When the filling speed is large, the volume of the cavity formed between the speed regulating plates 11 decreases, and the flow rate of the plant conditioning agent passing through the speed regulating plates 11 becomes relatively faster, and the filling speed of the plant conditioning agent also becomes faster. Because a certain amount of plant conditioning agent liquid has accumulated at the bottom of the container bottle 16 when the initial flow rate is slow, when the filling speed is increased, the plant conditioning agent filling impact becomes larger. The liquid layer accumulated at the bottom of the container bottle 16 is used to buffer the newly poured liquid, preventing the large impact from directly impacting the bottom of the container bottle 16, thereby causing damage or deformation of the bottom of the container bottle 16, thereby ensuring the effectiveness and safety of the plant conditioning agent filling.

[0027] Example 2

[0028] Based on Example 1, please refer to Figures 1-4 The bottom end of the filling head 1 is movably mounted with a container bottle 16, and the bottom end of the container bottle 16 is movably mounted with a movable plate 17. The bottom end of the movable plate 17 is fixedly mounted with a second spring 18, and the bottom end of the second spring 18 is fixedly mounted with a conveying platform 19. By arranging the movable plate 17, the second spring 18 and the conveying platform 19, it is not only convenient to distinguish whether the filling of the container bottle 16 is in the early state, but also the position of the container bottle 16 is changed by changing the state of the movable plate 17, thereby affecting the contact state of the positioning conductive block 5 and the resistance block 6, and then changing the power-on state of the movable electromagnet 8, thereby autonomously changing the volume of the cavity formed between the speed regulating plates 11, and then changing the filling flow rate of the plant adjustment agent, thereby improving and ensuring that the overall filling efficiency will not decrease, and at the same time, it also ensures that the container bottle 16 can always obtain the impact buffering effect.

[0029] See also Figures 1-4 The shape of the positioning conductive block 5 is "concave", and the top of the positioning conductive block 5 is conductive. The bottom of the filling head 1 is provided with a slide groove adapted to the structure of the positioning conductive block 5. The overall shape of the resistor block 6 is adapted to the internal concave formation of the positioning conductive block 5. The resistor block 6 is divided into two parts, the upper part of the resistor block 6 has a resistance value smaller than the resistance value of the lower part of the resistor block 6. One end of the resistor block 6 is fixedly connected to one end of the movable electromagnet 8 through an electrical wire, and one end of the positioning conductive block 5 is fixedly connected to the existing equipment power supply through an electrical wire.

[0030] See also Figures 1-4The fixed support plate 7 is in the shape of a circular ring, and the interior of the fixed support plate 7 is hollow. A slide groove that matches the shape of the movable electromagnet 8 is opened on the bottom surface of the fixed support plate 7. There are four movable electromagnets 8, and the movable electromagnets 8 are evenly distributed in a circular shape at the bottom of the fixed support plate 7. When the movable electromagnet 8 is energized, the magnetism displayed by the movable electromagnet 8 repels the magnetism of the first magnetic block 10, but attracts the magnetism of the second magnetic block 12.

[0031] See also Figures 1-4 The first magnetic block 10 and the second magnetic block 12 are both magnetic. There are four speed regulating plates 11, and the speed regulating plates 11 are evenly distributed in a circular shape below the bottom end of the filling valve 2. The shape of the speed regulating plate 11 is "L"-shaped, and the interior of the speed regulating plate 11 is hollow. The vertical section of the speed regulating plate 11 is rectangular, and the horizontal section is an isosceles trapezoid. The thickness of the upper surface of the horizontal section of the speed regulating plate 11 increases from the inside to the outside.

[0032] See also Figures 1-4 There are four liquid-absorbing cottons 13, and the liquid-absorbing cottons 13 are evenly distributed in a circular shape below the bottom end of the filling valve 2 and are adapted to the position of the speed regulating plate 11. The liquid-absorbing cotton 13 is triangular in shape and has elasticity and water absorption. By setting the speed regulating plate 11 and the liquid-absorbing cotton 13, when the container bottle 16 is filled with the plant adjustment, that is, the filling is completed, at this time, the conveying platform 19 moves downward, driving the container bottle 16 to move downward significantly, and the container bottle 16 is completely separated from the filling head 1. The positioning conductive block 5 also completely drops to the initial position. At this time, the positioning conductive block 5 is completely separated from the resistance block 6, and the power is cut off at the movable electromagnet 8. The magnetic repulsion of the movable electromagnet 8 on the first magnetic block 10 disappears. Under the elastic force of the first spring 9, the movable electromagnet 8 is reset inward, so that the speed regulating plate 11 moves inward and shrinks and resets together with the movable electromagnet 8. When the speed regulating plate 11 is completely reset, the four absorbent cottons 13 are also relatively closed and tightly attached to form a seal. At this time, the speed regulating plate 11 and the filling liquid are The liquid droplets accumulated and suspended at the opening of the valve 2 and the air outlet pipe 4 are absorbed by the surface of the absorbent cotton 13, thereby preventing the accumulated liquid from dripping to the outside and causing equipment pollution. In addition, when the next filling is performed, that is, the speed regulating plate 11 moves outward together with the movable electromagnet 8, the movable electromagnet 8 will also generate a magnetic attraction to the second magnetic block 12, causing the second magnetic block 12 to move upward. When the second magnetic block 12 moves upward, the second magnetic block 12 drives the absorbent cotton 13 to move outward through the traction rope 14. The thickness of the upper surface of the horizontal section 11 increases from the inside to the outside. When the absorbent cotton 13 moves outward, the speed regulating plate 11 squeezes the surface of the absorbent cotton 13, and then squeezes out the liquid absorbed by the inside of the absorbent cotton 13, so that the liquid flows into the interior of the container bottle 16 together with the new filling liquid, thereby avoiding the problem that residual liquid is retained at the liquid outlet when the existing filling equipment is in use, but the accumulated liquid is thrown out when the equipment moves, which not only causes equipment pollution, but also leads to waste of plant adjustments and a decrease in filling rate.

[0033] A filling method for a filling device for plant preparation production comprises the following steps:

[0034] S1. When performing plant adjustment filling, first, the container bottles 16 are evenly arranged on the top of the conveyor table 19, and the bottom end of each container bottle 16 is directly opposite the top end of the movable plate 17. Because the elastic force of the second spring 18 matches the gravity of the container bottle 16 when it is empty, when the container bottle 16 is placed empty, the top surface of the movable plate 17 is flush with the top surface of the conveyor table 19. Through the existing transmission equipment, the conveyor table 19 is continuously moved forward in a cycle, thereby driving the container bottles 16 on its surface to move forward;

[0035] S2. When the container bottle 16 moves to the position just below the filling head 1, the existing control system controls the filling head 1 to move downward. At the same time, the conveying platform 19 is also controlled to move upward to convey the container bottle 16 upward and dock with the bottom end of the filling head 1. When the bottom end of the filling head 1 and the top end of the container bottle 16 are completely against each other, the existing control system controls the butterfly valve 3 to open the valve, thereby starting the filling. At the same time, when the filling head 1 and the container bottle 16 are in contact, the positioning conductive block 5 is squeezed by the container bottle 16 and moves upward, so that the positioning conductive block 5 is completely in contact with the resistor block 6. The positioning conductive block 5 completely wraps the resistor block 6, and the top of the positioning conductive block 5 is in contact with the upper part of the resistor block 6, so that the current in the external existing equipment power supply passes through the positioning conductive block 5. The electric block 5, then passes through the resistor block 6 and is finally conducted to the movable electromagnet 8. Since the resistance value of the upper part of the resistor block 6 is small, the amount of electricity flowing through the movable electromagnet 8 is large, and thus the magnetism displayed by the movable electromagnet 8 is strong, and the magnetic repulsion of the movable electromagnet 8 on the first magnetic block 10 is also large. Since the position of the first magnetic block 10 is fixed, the movable electromagnet 8 moves outward under the action of the magnetic repulsion, and the movable electromagnet 8 moves outward a large distance. In this way, the volume of the cavity formed between the speed regulating plates 11 is large. When the butterfly valve 3 opens the valve, the plant adjustment passes through the lumen of the filling valve 2 and flows to the speed regulating plate 11. The flow rate of the plant adjustment is slow, and then when the plant adjustment flows out of the speed regulating plate 11 and then flows into the container bottle 16, the plant adjustment has a small impact on the liquid at the bottom of the container bottle 16, thereby avoiding damage to the bottom of the container bottle 16;

[0036] S3. After a period of filling, a certain amount of plant adjustment agent has accumulated at the bottom of the container bottle 16. Due to the gravity of the plant adjustment agent, the downward pressure of the container bottle 16 on the movable plate 17 increases, causing the movable plate 17 to squeeze the second spring 18 downward. The elastic force of the second spring 18 itself is less than the existing downward pressure, and then the movable plate 17 moves downward, and the container bottle 16 also moves downward. When the container bottle 16 moves downward, the top of the container bottle 16 is separated from the filling head 1 for a distance, and the positioning conductive block 5 moves downward and partially separates from the resistor block 6. Then the top of the positioning conductive block 5 contacts the lower part of the resistor block 6 for communication. Electricity, because the resistance value of the lower part of the resistor block 6 is large, the amount of current flowing through the active electromagnet 8 becomes smaller, the magnetic repulsion of the active electromagnet 8 on the first magnetic block 10 becomes smaller, and the active electromagnet 8 moves back inward again, but because the magnetic repulsion is still there, the active electromagnet 8 will not completely reverse reset, but the cavity formed between the speed regulating plates 11 will be affected by the reverse reset of the active electromagnet 8 and its volume will be reduced. At this time, the flow rate of the plant adjustment agent begins to increase, and then the filling speed also increases. The plant adjustment agent liquid layer accumulated at the bottom of the container bottle 16 is used to buffer the newly poured liquid to avoid a large impact directly to the bottom of the container bottle 16;

[0037] S4. When the container bottle 16 is filled with the planting agent, that is, the filling is completed, at this time, the conveying platform 19 moves downward, and the container bottle 16 moves downward significantly, and the container bottle 16 is completely separated from the filling head 1, and then the positioning conductive block 5 also falls completely to the initial position. After the positioning conductive block 5 is completely separated from the resistance block 6, the movable electromagnet 8 is powered off, and the magnetic repulsion of the movable electromagnet 8 on the first magnetic block 10 disappears. Under the elastic force of the first spring 9, the movable electromagnet 8 is completely reset inward and returned to the initial position. At the same time, the speed regulating plate 11 moves inward and shrinks and resets together with the movable electromagnet 8. When the speed regulating plate 11 is completely reset, the four liquid-absorbing cottons 13 are relatively closed to form a seal. At this time, the liquid droplets suspended at the opening of the speed regulating plate 11, the filling valve 2 and the air outlet pipe 4 all drip onto the surface of the liquid-absorbing cotton 13 and are absorbed by the liquid-absorbing cotton 13. When a new empty container bottle 16 moves to the bottom of the filling head 1, and a new round of filling work begins, it can be seen from the above steps that the speed regulating plate 11 moves outward together with the movable electromagnet 8. At this time, the movable electromagnet 8 generates a magnetic attraction on the second magnetic block 12, causing the second magnetic block 12 to move upward. When the second magnetic block 12 moves upward, the second magnetic block 12 drives the absorbent cotton 13 to move outward through the traction rope 14. Because the thickness of the upper surface of the horizontal section of the speed regulating plate 11 increases from the inside to the outside, when the absorbent cotton 13 moves outward, the speed regulating plate 11 squeezes the surface of the absorbent cotton 13, and then squeezes out the liquid absorbed by the inside of the absorbent cotton 13, so that the liquid flows into the interior of the container bottle 16 together with the new filling liquid, until the interior of the container bottle 16 is filled with the plant adjustment agent. Therefore, the cyclic filling can be completed by repeating the above steps.

The liquid-absorbing cottons (13) are triangular in shape and have elasticity and water absorption.

7. The filling method of a filling device for planting and regulating the production according to claim 1, characterized in that: The following steps are involved: S1. When performing plant adjustment filling, first, the container bottles (16) are evenly arranged on the top of the conveying platform (19), and the bottom end of each container bottle (16) is located directly opposite the top of the movable plate (17). Because the elastic force of the second spring (18) matches the gravity of the container bottle (16) when it is empty, when the container bottle (16) is placed empty, the top surface of the movable plate (17) is flush with the top surface of the conveying platform (19). Through the existing transmission equipment, the conveying platform (19) is continuously moved forward in a cycle, thereby driving the container bottles (16) on its surface to move forward; S2. When the container bottle (16) moves to the position directly below the filling head (1), the existing control system controls the filling head (1) to move downward, and at the same time, controls the conveying platform (19) to move upward, so that the container bottle (16) is conveyed upward and contacts the bottom end of the filling head (1). When the bottom end of the filling head (1) and the top end of the container bottle (16) are completely against each other, the existing control system controls the butterfly valve (3) to open the valve, thereby starting filling. At the same time, when the filling head (1) and the container bottle (16) contact each other, the positioning conductive block (5) is squeezed by the container bottle (16) and moves upward, so that the positioning conductive block (5) and the resistor block (6) are completely in contact. The positioning conductive block (5) completely wraps the resistor block (6), and the top of the positioning conductive block (5) contacts the upper part of the resistor block (6). Therefore, the current in the external existing equipment power supply passes through the positioning conductive block. The electric block (5) is then passed through the resistor block (6) and finally conducted to the movable electromagnet (8). Since the resistance value of the upper part of the resistor block (6) is small, the amount of current flowing through the movable electromagnet (8) is large, and thus the magnetism displayed by the movable electromagnet (8) is strong, and the magnetic repulsion of the movable electromagnet (8) to the first magnetic block (10) is also large. Since the position of the first magnetic block (10) is fixed, the movable electromagnet (8) moves outward under the action of the magnetic repulsion, and the distance the movable electromagnet (8) moves outward is large. In this way, the volume of the cavity formed between the speed regulating plates (11) is large. When the butterfly valve (3) opens the valve, the plant regulating agent passes through the lumen of the filling valve (2) and flows to the speed regulating plate (11). The flow rate of the plant regulating agent is slow. Then, when the plant regulating agent flows out of the speed regulating plate (11) and flows into the container bottle (16), the plant regulating agent has a small impact on the liquid at the bottom of the container bottle (16), thereby avoiding damage to the bottom of the container bottle (16); S3. After a period of filling, a certain amount of plant adjustment agent has accumulated at the bottom of the container bottle (16). Due to the gravity of the plant adjustment agent, the downward pressure of the container bottle (16) on the movable plate (17) increases, causing the movable plate (17) to press the second spring (18) downward. The elastic force of the second spring (18) itself is less than the existing downward pressure, and then the movable plate (17) moves downward, and the container bottle (16) also moves downward. When the container bottle (16) moves downward, the top of the container bottle (16) is separated from the filling head (1) by a distance, and the positioning conductive block (5) moves downward and is partially separated from the resistor block (6). Then, the top of the positioning conductive block (5) and the lower part of the resistor block (6) are separated. When the two contact each other and are energized, the resistance value of the lower part of the resistor block (6) is large, and the amount of current flowing through the movable electromagnet (8) becomes smaller, and the magnetic repulsion of the movable electromagnet (8) on the first magnetic block (10) becomes smaller, and the movable electromagnet (8) moves back inward again, but because the magnetic repulsion is still in effect, the movable electromagnet (8) will not completely reset in the reverse direction, but the cavity formed between the speed regulating plates (11) will be reduced in volume due to the reverse reset of the movable electromagnet (8). At this time, the flow rate of the plant adjustment agent begins to increase, and the filling speed also increases. The plant adjustment agent liquid layer accumulated at the bottom of the container bottle (16) is used to buffer the newly poured liquid, avoiding a large impact directly hitting the bottom of the container bottle (16); S4. When the container bottle (16) is filled with the plant adjustment agent, that is, the filling is completed, at this time, the conveyor (19) moves downward, and the container bottle (16) moves downward significantly, and the container bottle (16) is completely separated from the filling head (1), and then the positioning conductive block (5) also completely falls to the initial position. After the positioning conductive block (5) is completely separated from the resistance block (6), the power is cut off at the movable electromagnet (8), and the magnetic repulsion of the movable electromagnet (8) on the first magnetic block (10) disappears. Under the elastic force of the spring (9), the movable electromagnet (8) is completely reset inward and returned to its initial position. At the same time, the speed regulating plate (11) moves inward and shrinks and resets together with the movable electromagnet (8). When the speed regulating plate (11) is completely reset, the four liquid-absorbing cottons (13) are relatively closed to form a seal. At this time, the liquid droplets accumulated and suspended at the opening of the speed regulating plate (11), the filling valve (2) and the outlet pipe (4) are all dripped onto the surface of the liquid-absorbing cotton (13) and absorbed by the liquid-absorbing cotton (13). When a new empty bottle container (16) moves to the bottom of the filling head (1), a new round of filling work begins. As can be seen from the above steps, the speed regulating plate (11) moves outward together with the movable electromagnet (8). At this time, the movable electromagnet (8) generates a magnetic attraction force on the second magnetic block (12), causing the second magnetic block (12) to move upward. When the second magnetic block (12) moves upward, the second magnetic block (12) drives the absorbent cotton (13) through the traction rope (14). ) moves outward, because the thickness of the upper surface of the horizontal section of the speed regulating plate (11) increases from the inside to the outside, the liquid absorbent cotton (13) is squeezed by the speed regulating plate (11) on the surface of the liquid absorbent cotton (13) when it moves outward, and then the liquid absorbed by the liquid absorbent cotton (13) is squeezed outward, so that the liquid flows into the interior of the container bottle (16) together with the new filling liquid until the interior of the container bottle (16) is filled with the plant adjustment. Therefore, the cyclic filling can be completed by repeating the above steps.
