Description

Technical Field

[0001] The present application relates to the technical field of filling devices, and specifically to an automatic filling device for the production of wheat Fusarium fungicide. Background Art

[0002] Filling machinery is a machine for filling objects. It is a small category of packaging machines. From the perspective of the degree of production automation, it can be divided into semi-automatic filling machines and fully automatic filling production lines. From the perspective of material packaging, it can be divided into liquid filling machines, paste filling machines, powder filling machines and granule filling machines.

[0003] An existing patent (publication number: CN219449274U) discloses a stirring and filling device for HPV gel production and processing. The device comprises a support plate, a support column secured to its lower surface, a support foot secured to its lower surface, a transport device secured to its upper surface, a fixed block secured to its upper surface, side panels secured to its upper surface, located to the left and right of the fixed block, a top panel secured to its upper surface, and a filling device secured to its upper surface. A stirring mechanism for feeding the filling device is located on the left side of the filling device. This device utilizes a positioning mechanism that drives a dual-axis motor to rotate threaded rods on both sides, causing a threaded sleeve to move toward the motor. A connecting plate drives a push block to push a positioning block against the fixed block, preventing the fixed block from shifting during transport and potentially causing filling failure.

[0004] In order to avoid splashing of liquid during filling, the above-mentioned filling devices and common filling devices often insert the bottom end of the nozzle into the interior of the container. However, when the rated filling volume of the container is reached, the bottom end of the nozzle will be contaminated with liquid, which may easily cause liquid to drip onto the conveying device. Secondly, the residual liquid in the nozzle will also drip onto the conveying device under the action of gravity and internal pressure, and the dripping sterilizer may easily corrode the conveyor. Utility Model Content

[0005] In response to the deficiencies of the prior art, the present application provides an automatic filling device for the production of wheat Fusarium fungicide, which has the advantages of anti-drip and the like, and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an automatic filling device for producing a wheat Fusarium fungicide, comprising a nozzle, the inner wall of the nozzle being conical, and a sealing component being provided on the inner wall of the bottom end of the nozzle;

[0007] The closing assembly includes a closing ball, a connecting rod, a fixing ring and a first spring;

[0008] A cleaning ring is slidably sleeved on the outer surface of the nozzle, and a plurality of annular grooves are formed on the bottom of the cleaning ring.

[0009] Through the above solution, by designing a unique closing component, including a closing ball, a connecting rod, a fixing ring and a first spring, the function of automatically closing the bottom end of the nozzle after filling is completed is achieved. This design ensures that when the fungicide reaches the set filling volume, the residual liquid in the nozzle is effectively blocked by the closing ball, avoiding corrosion problems caused by liquid adhering to the bottom end of the nozzle or residual liquid inside dripping onto the conveying device, thereby ensuring the cleanliness of the production environment and the service life of the equipment.

[0010] Furthermore, the closing ball is slidably connected to the bottom end of the nozzle, the bottom end of the connecting rod is fixedly connected to the closing ball, the fixing ring is fixedly connected to the inner wall of the nozzle, the connecting rod is plugged into the fixing ring, and the two ends of the first spring are fixedly connected to the fixing ring and the closing ball respectively.

[0011] Through the above scheme and the setting of the closing component, it can be achieved that when the fungicide is sprayed inside the nozzle, the closing ball moves downward under pressure, thereby causing the closing ball to break contact with the bottom end of the nozzle, causing the fungicide to be sprayed from both sides. When the infusion is completed, the closing ball is reset by the reset of the first spring, thereby sealing the bottom end of the nozzle, which can effectively prevent residual fungicide inside the nozzle from dripping onto the conveyor.

[0012] Furthermore, the bottom cross-section of each annular groove is funnel-shaped.

[0013] Through the above solution and the provision of the annular groove, it is possible to easily match with different bottle openings.

[0014] Furthermore, a blocking ring is fixedly connected to the bottom end of the nozzle, and the upper surface of the blocking ring contacts the bottom of the cleaning ring.

[0015] With the above solution and the provision of the blocking ring, it is possible to prevent the cleaning ring from being separated from the nozzle.

[0016] Furthermore, a reset ring is fixedly connected to the outer surface of the nozzle, and a second spring is fixedly connected between the reset ring and the cleaning ring.

[0017] Through the above solution and the provision of the second spring, the purpose of resetting the cleaning ring can be achieved.

[0018] Furthermore, the outer surface of the nozzle and the inner wall of the cleaning ring are both configured as smooth surfaces.

[0019] According to the above solution, the nozzle and the cleaning ring are provided with smooth surfaces, so that the friction resistance between the two can be reduced.

[0020] Furthermore, a flange is fixedly connected to the top end of the nozzle.

[0021] Through the above solution, the flange is provided to facilitate connection with external conveying devices.

[0022] Furthermore, the top end of the connecting rod is fixedly connected to a limit plate.

[0023] Through the above solution and the provision of the limiting plate, the connecting rod can be effectively prevented from falling off from the fixing ring.

[0024] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0025] This automatic filling device for the production of wheat Fusarium fungicide realizes the function of automatically closing the bottom end of the nozzle after filling is completed by designing a unique sealing component, including a sealing ball, a connecting rod, a fixing ring and a first spring. This design ensures that when the fungicide reaches the set filling volume, the residual liquid in the nozzle is effectively blocked by the sealing ball, avoiding corrosion problems caused by liquid adhering to the bottom end of the nozzle or residual liquid dripping onto the conveying device, thereby ensuring the cleanliness of the production environment and the service life of the equipment.

[0026] This automatic filling device for the production of wheat Fusarium fungicide has a cleaning ring that slides on the outer surface of the nozzle and an annular groove design at its bottom, which enables the device to adapt to bottle mouths of different sizes, enhancing the versatility and flexibility of the equipment. In addition, the funnel-shaped design of the annular groove further optimizes the docking effect with the bottle mouth, reducing the risk of leakage during the filling process. At the same time, when the nozzle is reset, the cleaning ring can scrape the liquid attached to the outer surface of the nozzle, effectively reducing the dripping of the reagent.

[0033] 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.

[0034] See also Figure 1 、 Figure 2 and Figure 3 In this embodiment, an automatic filling device for the production of wheat Fusarium fungicide includes a nozzle 1. The inner wall of the nozzle 1 is conical, and a closing component 2 is provided on the inner wall of the bottom end of the nozzle 1. The top of the nozzle 1 is fixedly connected to a flange 8. The setting of the flange 8 facilitates connection with an external conveying device.

[0035] See also Figure 1 、 Figure 3 and Figure 4 The closing assembly 2 includes a closing ball 201, a connecting rod 202, a fixing ring 203 and a first spring 204. The closing ball 201 is slidably connected to the bottom end of the nozzle 1, the bottom end of the connecting rod 202 is fixedly connected to the closing ball 201, the fixing ring 203 is fixedly connected to the inner wall of the nozzle 1, the connecting rod 202 is plugged into the fixing ring 203, and the two ends of the first spring 204 are respectively fixedly connected to the fixing ring 203 and the closing ball 201. Through the setting of the closing assembly 2, when the disinfectant is sprayed from the inside of the nozzle 1, the closing ball 201 is pressured to move downward, thereby causing the closing ball 201 to disengage from the bottom end of the nozzle 1, causing the disinfectant to be sprayed from both sides. When the perfusion is completed, the closing ball 201 is reset under the reset of the first spring 204, thereby closing the bottom end of the nozzle 1, which can effectively prevent the residual disinfectant inside the nozzle 1 from dripping onto the conveyor.

[0036] See also Figure 1 、 Figure 2 and Figure 3 The top of the connecting rod 202 is fixedly connected to the limiting disk 9. Through the setting of the limiting disk 9, the connecting rod 202 can be effectively prevented from falling off from the fixing ring 203. The outer surface of the nozzle 1 is slidably sleeved with a cleaning ring 3. The bottom of the cleaning ring 3 is provided with a plurality of annular grooves 4. The bottom cross-section of each annular groove 4 is funnel-shaped. Through the setting of the annular grooves 4, it is convenient to cooperate with different bottle mouths. The bottom end of the nozzle 1 is fixedly connected with a blocking ring 5. The upper surface of the blocking ring 5 contacts the bottom of the cleaning ring 3. Through the setting of the blocking ring 5, the cleaning ring 3 can be prevented from detaching from the nozzle 1.

[0037] See also Figure 1 、 Figure 2 and Figure 3The outer surface of the nozzle 1 is fixedly connected with a reset ring 6, and a second spring 7 is fixedly connected between the reset ring 6 and the cleaning ring 3. Through the setting of the second spring 7, the purpose of resetting the cleaning ring 3 can be achieved. The outer surface of the nozzle 1 and the inner wall of the cleaning ring 3 are both set as smooth surfaces. By setting the nozzle 1 and the cleaning ring 3 as smooth surfaces, the friction resistance between the two can be reduced.

[0038] In this embodiment, an automatic filling device for the production of wheat Fusarium fungicide is designed. The unique sealing component 2, including a sealing ball 201, a connecting rod 202, a fixing ring 203 and a first spring 204, realizes the function of automatically closing the bottom end of the nozzle 1 after filling is completed. This design ensures that when the fungicide reaches the set filling volume, the residual liquid in the nozzle 1 is effectively blocked by the sealing ball 201, avoiding corrosion problems caused by liquid adhering to the bottom end of the nozzle 1 or residual liquid dripping onto the conveying device, thereby ensuring the cleanliness of the production environment and the service life of the equipment. The cleaning ring 3 slidingly sleeved on the outer surface of the nozzle 1 and the annular groove 4 at the bottom design enable the device to adapt to bottle mouths of different sizes, enhancing the versatility and flexibility of the equipment. In addition, the funnel-shaped design of the annular groove 4 further optimizes the docking effect with the bottle mouth and reduces the risk of leakage during the filling process. At the same time, when the nozzle 1 is reset, the cleaning ring 3 can scrape the liquid adhering to the outer surface of the nozzle 1, effectively reducing the dripping of the reagent.

[0039] The working principle of the above embodiment is as follows: the filling device is in standby mode, and the closing ball 201 of the nozzle 1 is tightly attached to the bottom end of the nozzle 1 under the action of the first spring 204, closing the outlet of the nozzle 1 to prevent the residual liquid inside from dripping. The cleaning ring 3 is maintained at the initial position of the outer surface of the nozzle 1 by the action of the second spring 7, ready for cleaning after filling. The wheat fusarium fungicide container to be filled is placed on the conveying device and gradually approaches the filling head as the conveying device moves. The cleaning ring 3 is adapted to the bottle mouth through the annular groove 4 at its bottom according to the size of the container to ensure the sealing and accuracy of the filling process. When the container reaches the specified position, the control system issues a command to start the filling process, and the nozzle 1 begins to descend. Until its bottom end enters a certain depth inside the container to prevent liquid from splashing. At the same time, the closing ball 201 is subjected to the pressure of the sterilant liquid and moves downward through the connecting rod 202, compressing the first spring 204, so that the closing ball 201 is out of contact with the bottom end of the nozzle 1, allowing the sterilant to be sprayed from both sides of the nozzle 1. After the filling is completed, the nozzle 1 starts to rise and leave the container mouth. At this time, the closing ball 201 quickly returns to the bottom end of the nozzle 1 under the reset action of the first spring 204, and re-seals the nozzle 1 outlet to prevent residual liquid from dripping. During the rising process of the nozzle 1, due to the reset pressure of the second spring 7, the cleaning ring 3 can be tightly attached to the bottle mouth, and at the same time, the outer surface of the nozzle 1 is scraped, so that the liquid attached to it drips into the container.
