Description

Technical Field

[0001] This utility model relates to the field of pesticide filling technology, and in particular to an anti-drip nozzle assembly for a liquid pesticide filling line. Background Technology

[0002] Liquid pesticide filling lines are automated production lines designed specifically for liquid products such as pesticides and fertilizers. They integrate functions such as bottle washing, filling, capping, sealing, and labeling, and achieve fully automated operation through program control.

[0003] Currently, the nozzle assemblies of existing liquid pesticide filling lines can usually achieve the lifting and lowering of the filling head to meet the needs of efficient and precise filling. Although this improves the quality of filling operations to a certain extent, it cannot achieve the automatic opening and closing of the filling port during the lifting and lowering of the filling head. This means that the filling port cannot be sealed in time after filling, which leads to pesticide leakage. This not only wastes pesticide resources but also pollutes the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot automatically open and close the filling port during the lifting and lowering of the filling head, resulting in pesticide leakage, which not only wastes pesticide resources but also pollutes the surrounding environment. Therefore, this invention proposes an anti-drip nozzle assembly for liquid pesticide filling lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-drip nozzle assembly for a liquid pesticide filling line includes:

[0007] A frame and a filling head, wherein a conveyor belt is fixedly installed on the top of the frame and a support base is fixedly installed on one side of the top of the frame;

[0008] The support base is equipped with a lifting mechanism, which is used to move the filling head up and down. The lifting mechanism is also equipped with a sealing component, which is used to seal the filling port of the filling head.

[0009] In one possible design, the lifting mechanism includes an electric cylinder fixedly mounted on the top of the support base. The output end of the electric cylinder is fixedly mounted with a connecting seat, and a filling hopper is fixedly mounted on one side of the connecting seat. The filling head is fixedly mounted on the bottom of the filling hopper and is connected to the filling hopper. The top of the filling hopper is covered with a cover plate, and a conveying pipe is fixedly connected to the top of the cover plate.

[0010] In one possible design, the sealing assembly includes a fixed frame fixedly mounted on one side of the electric cylinder, a connecting rod hinged to the inner side of the fixed frame, a connecting frame hinged to the other end of the connecting rod, a cap hinged to one side of the filling head for sealing the filling port of the filling head, and one side of the connecting frame fixedly connected to the bottom of the cap.

[0011] In one possible design, a plug is fixedly installed at the center of the side of the cap near the filling port of the filling head, and a sealing gasket is embedded in the outer ring of the plug on one side of the cap.

[0012] In one possible design, a turntable is rotatably mounted on the top of the platform next to the conveyor belt. The outer circumference of the turntable has a plurality of evenly spaced grooves for accommodating filling bottles. A rotating motor is fixedly mounted on the bottom of the platform, and the output shaft of the rotating motor is fixedly connected to the bottom of the turntable.

[0013] In one possible design, two guide frames are symmetrically fixed on one side of the conveyor belt to guide the filling bottles into the turntable.

[0014] In this application, when the device is first used, the liquid pesticide to be filled is first transported to the storage container connected to the conveying pipe through a suitable conveying equipment to ensure that the pesticide supply is sufficient and free of impurities. Then the entire device is connected to the power supply to prepare for the filling operation.

[0015] The empty bottles are then placed at the beginning of the conveyor belt (or other conveying equipment can be used to transport the empty bottles to the beginning of the conveyor belt). The conveyor belt starts, and the bottles move forward under the drive of the conveyor belt. The guide frames on both sides of the conveyor belt guide the bottles so that they can move accurately towards the turntable, preventing the bottles from deviating or tipping over during the transport process. When the bottles approach the turntable, they smoothly enter the grooves on the outer ring of the turntable under the guidance of the guide frames. During this process, the rotating motor starts synchronously, and the output shaft of the rotating motor drives the turntable to rotate. The grooves on the turntable bring the bottles to the bottom of the filling head in sequence, achieving precise positioning of the bottles.

[0016] Once the bottle reaches the bottom of the filling head and is accurately positioned, the turntable pauses briefly to form a positioning station. The electric cylinder starts, and its output end moves downward, causing the connecting seat, filling hopper, and filling head fixed at the bottom of the filling hopper to descend synchronously. This allows the filling head to gradually approach the bottle. During the descent of the filling head, the connecting rod pulls the cap through the connecting frame. Since the cap is hinged to the filling head, under the action of the pulling force, the cap rotates around the hinge point with the filling head and gradually unfolds, releasing the blockage of the filling port of the filling head. At this time, the liquid pesticide can flow out through the filling port of the filling head.

[0017] As the filling head continues to descend until it approaches the bottle opening, the electric cylinder stops descending (the filling head approaches the bottle opening to prevent liquid splashing during filling). At this point, the liquid pesticide flows out from the filling port of the filling head and into the bottle. During the filling process, the operator can observe the filling situation to check for any abnormalities, such as pesticide leakage, excessively fast or slow filling speed, etc. At the same time, the flow sensor on the filling head can monitor the filling volume in real time to ensure stable product quality.

[0018] When the filling flow detected by the flow sensor reaches the predetermined filling volume, the electric cylinder starts and its output end moves upward, driving the connecting seat, filling hopper and filling head to rise synchronously, so that the filling head gradually moves away from the bottle mouth. During the rising process of the filling head, the connecting rod pushes the cap through the connecting frame, so that the cap rotates in the opposite direction around the hinge point with the filling head. The cap gradually approaches the filling port of the filling head, the plug enters the filling port, and the sealing gasket fits tightly with the area around the filling port, thereby sealing the filling port of the filling head and preventing pesticide leakage.

[0019] The turntable continues to rotate, moving the filled bottles away from under the filling head and carrying them off the workstation for subsequent capping. At the same time, the empty bottles in the next turntable groove are rotated to the bottom of the filling head for filling. After filling and sealing, the bottles are rotated to the rear end of the conveyor belt and then transported to the next process (such as labeling) by the conveyor belt.

[0020] This utility model has the following beneficial effects:

[0021] The present invention features a lifting mechanism that allows for adjustment of the filling head's height. During filling, the filling head is lowered to a suitable position, ensuring accurate injection of liquid pesticides into the filling bottle while preventing liquid splashing, thus maintaining a clean and pollution-free working environment.

[0022] In this invention, the sealing component ensures that, during non-filling stages, the cap tightly seals the filling nozzle, preventing pesticide leakage due to gravity or slight equipment vibration. This avoids pesticide waste and pollution of surrounding equipment and the environment. When filling is required, the cap opens by lowering the electric cylinder, ensuring smooth pesticide flow. After filling, the cap re-locks the nozzle as the electric cylinder rises, further eliminating the risk of leakage and ensuring the efficiency, cleanliness, and safety of the entire filling process.

[0023] This invention combines a lifting mechanism with a sealing component, which can both lift the filling head to achieve efficient and accurate filling and prevent liquid splashing, and automatically open during filling and automatically seal after filling, effectively avoiding pesticide leakage and reducing waste and environmental pollution.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In one embodiment

[0031] Reference Figure 1-4 A nozzle assembly, comprising:

[0032] The system comprises a frame 1, a conveyor belt 2, a support base 101, a lifting mechanism, a sealing assembly, a filling head 5 (equipped with a flow sensor), a turntable 10, a rotating motor 12, and guide frames 13. Through the coordinated operation of these components, efficient, precise, and leak-proof liquid pesticide filling operations are achieved. The frame 1 serves as the main support for the entire system, with the conveyor belt 2 fixedly mounted on its top. The conveyor belt 2 is horizontally positioned, and its motor drives the rotating rollers via a synchronous belt and synchronous pulley. The rotation of the rollers drives the belt to move, which is used to transport the bottles to be filled, providing a continuous supply of materials for the filling operation. On one side of the conveyor belt 2, two guide frames 13 are symmetrically fixed. These two guide frames 13 are set at a certain angle, and their function is to guide the bottles to smoothly enter the grooves 11 of the turntable 10, ensuring the accuracy of the bottle's position during the conveying process.

[0033] A support base 101 is fixedly installed on one side of the top of the platform 1. The support base 101 provides the installation foundation for the lifting mechanism. The lifting mechanism includes an electric cylinder 3 fixedly installed on the top of the support base 101. The electric cylinder 3 serves as a power source, and a connecting seat is fixedly installed at its output end. A filling hopper 4 is fixedly installed on one side of the connecting seat. The filling hopper 4 is funnel-shaped and has a cover plate on its top. A conveying pipe 401 is fixedly connected to the top of the cover plate. The conveying pipe 401 is connected to an external pesticide storage device and is used to convey liquid pesticide into the filling hopper 4. A filling head 5 is fixedly installed at the bottom of the filling hopper 4 and is connected to the filling hopper 4. Liquid pesticide flows into the filling head 5 through the filling hopper 4 and is finally filled into the filling bottle.

[0034] The sealing assembly works closely with the lifting mechanism to seal the filling port of the filling head 5. It includes a fixed frame 9 fixedly mounted on one side of the electric cylinder 3, a connecting rod 8 hinged to the inner side of the fixed frame 9, and a connecting frame 7 hinged to the other end of the connecting rod 8. A cap 6 for sealing the filling port of the filling head 5 is hinged to one side of the filling head 5. One side of the connecting frame 7 is fixedly connected to the bottom of the cap 6. To enhance the sealing effect, a plug 601 is fixedly mounted at the center of the side of the cap 6 near the filling port of the filling head 5. The diameter of the plug 601 is adapted to the inner diameter of the filling port of the filling head 5, so that it can be tightly inserted into the filling port. At the same time, a sealing gasket 602 is embedded in the outer ring of the plug 601 on one side of the cap 6. The sealing gasket 602 further improves the sealing performance and prevents pesticide leakage.

[0035] This application can be used in the field of anti-drip nozzle assembly technology for liquid pesticide filling lines, and can also be used in other fields applicable to this application.
