Description

Technical Field

[0001] This utility model belongs to the technical field of quantitative filling equipment, and relates to a quantitative filling equipment for chemical cleaning reagents. Background Technology

[0002] The chemical cleaning reagent quantitative filling equipment is a device used for precise metering and filling of chemical cleaning agents. It uses a pump to deliver the cleaning agent from the storage tank to the filling head, and uses devices such as flow meters, weight sensors or quantitative pumps to accurately measure the cleaning agent dosage for each filling. Then, according to the set value, the equipment controls the opening and closing of the valve to fill the container with the cleaning agent. When the preset amount is reached, the valve automatically closes, completing one filling cycle.

[0003] For example, patent CN114261937B discloses a quantitative filling device for chemical liquids, which includes a support body; a transmission mechanism disposed inside the support body; a limiting mechanism with a clamping unit; and a self-locking mechanism with an unlocking unit. This invention, by setting a self-locking mechanism, allows the filling head to be in a cut-off state when not aligned with the bottle port. The movement and contraction of the first and second pressure blocks provide power to the unlocking units on the first and second fixed rings, thereby pushing the self-locking ball to release the blockage of the first and second fixed rings, enabling the filling head to be open. When the filling head is not aligned with the bottle port, the first and second pressure blocks cannot contract simultaneously, thus keeping the filling head in a cut-off state and effectively preventing the chemical liquid from spraying out even when the filling head is not aligned with the bottle port.

[0004] When using the above technology, the following technical problems were found in the existing technology: When filling chemical cleaning reagents, there is a certain distance between the filling head and the bottle. When the chemical cleaning reagent is quickly filled into the bottle, due to the impact force and speed of the liquid, the cleaning reagent is prone to collide with the bottle wall and generate eddies and shear forces, which can easily form bubbles, which has an adverse effect on filling accuracy and product quality. Utility Model Content

[0005] The technical problem this invention aims to solve is that when filling chemical cleaning reagents, there is a certain distance between the filling head and the bottle. When the chemical cleaning reagent is rapidly poured into the bottle, due to the impact force and speed of the liquid, the cleaning reagent is prone to collide with the bottle wall, generating eddies and shear forces, which easily form bubbles, adversely affecting filling accuracy and product quality.

[0006] The present invention discloses a quantitative filling device for chemical cleaning reagents, comprising a base, a conveyor belt installed on one side of the base, a placement plate installed at the end of the base away from the conveyor belt, a controller and a quantitative filling device respectively installed at both ends of one side of the base, a storage tank installed in the middle of one side of the base, and a liquid outlet chamber provided on one side of the quantitative filling device.

[0007] A filling assembly, which is mounted on a quantitative filling device, is used in conjunction with a liquid dispensing chamber;

[0008] A stirring assembly is installed on the liquid outlet chamber, and the stirring assembly is used in conjunction with the liquid outlet chamber;

[0009] A clamping assembly is disposed on a placement plate and is used in conjunction with a filling assembly.

[0010] The filling assembly includes an infusion tubing, a support frame, and a first servo motor. One end of the infusion tubing is connected to the inside of the outlet chamber. The end of the infusion tubing away from the outlet chamber is connected to an infusion rigid tube. A filling head is installed at the end of the infusion rigid tube away from the infusion tubing. A solenoid valve is installed at the end of the infusion rigid tube near the filling head. The support frame is fixed to one side of the quantitative filling device. The first servo motor is mounted on the quantitative filling device. One end of the quantitative filling device is rotatably connected to a lead screw connected to the output end of the first servo motor. A connecting frame is connected to the lead screw and nut pair. One end of the connecting frame is fixed to the outer wall of the end of the infusion rigid tube away from the filling head.

[0011] The stirring assembly includes a transmission rod and a rotating rod. One end of the rotating rod is rotatably mounted on the outer wall of the storage tank, and the rotating rod is rotatably mounted inside the storage tank. One end of the rotating rod penetrates the interior of the storage tank. A first bevel gear set is provided between the end of the rotating rod located outside the storage tank and the transmission rod. A pulley set is provided between the end of the transmission rod away from the first bevel gear set and the end of the lead screw. Multiple stirring rods are installed in the area of ​​the rotating rod located inside the storage tank.

[0012] A filling pipe is fixedly connected to the top of the liquid storage tank. A limiting ring is fixedly connected to the inner wall of the filling pipe. A filter screen is movably connected to the limiting ring. Magnets are correspondingly provided in the contact areas between the edge of the filter screen and the limiting ring.

[0013] The clamping assembly includes a threaded cylinder and a second servo motor. The threaded cylinder is rotatably mounted on the base, and the second servo motor is mounted on the base. A second bevel gear set is provided between the output end of the second servo motor and the threaded cylinder. A screw rod is threaded through both ends of the threaded cylinder. A mounting bracket is fixedly connected to the end of the screw rod away from the threaded cylinder. A clamping plate is fixedly connected to the end of the mounting bracket away from the screw rod. The clamping plate is slidably connected to the surface of the placement plate.

[0014] The inner circumferential surface of the clamping plate is provided with a rubber pad.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the first servo motor in the forward direction, the infusion tube and filling head can be driven by the lead screw and connecting frame to gradually extend into the container to be filled, so as to directly insert the filling head into the container, reduce the distance between the filling head and the container, and allow the filling liquid to enter the bottle more directly and smoothly, reducing the collision between the liquid flow and the container, thereby reducing the probability of air bubble formation. At the same time, by rotating the first servo motor in the reverse direction, the infusion tube and filling head can be driven by the lead screw and connecting frame to gradually extend out of the container to be filled, thereby reducing the contact between the liquid inside the container and the infusion tube and filling head, and leaving residue on their surfaces, thus improving the quality of the subsequent filled products.

[0016] The stirring component can agitate the liquid inside the storage tank during the filling process, ensuring the uniformity of the component distribution within the cleaning reagent and thus improving the quality of the cleaning reagent poured into the container. Furthermore, the filter screen filters out impurities in the liquid entering the storage tank, ensuring the cleanliness of the liquid entering the storage tank. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1: As Figures 1-4 As shown, a chemical cleaning reagent quantitative filling device includes a base 1. A conveyor belt 2 is installed on one side of the base 1 to transport containers to the filling position. A placement plate 3 is installed at the end of the base 1 away from the conveyor belt 2 for placing containers to be filled. A controller 4 and a quantitative filling device 6 are respectively installed at both ends of one side of the base 1. The controller 4 is used to control the entire filling process, including starting, stopping, parameter setting, etc. The quantitative filling device 6 is used to accurately measure and fill the cleaning agent into the containers. The above control means are common technologies in the existing quantitative filling field. A storage tank 5 is installed in the middle of one side of the base 1 for storing the cleaning agent to be filled. A dispensing chamber 7 is provided on one side of the quantitative filling device 6 for receiving the cleaning agent delivered from the storage tank 5.

[0028] The filling assembly is mounted on the quantitative filling device 6 and is used in conjunction with the liquid dispensing chamber 7.

[0029] A stirring assembly is installed on the liquid outlet chamber 7 and is used in conjunction with the liquid outlet chamber 7.

[0030] A clamping assembly is disposed on the placement plate 3 and is used in conjunction with the filling assembly.

[0031] Example 2: Figures 1-4 As shown, the filling assembly includes an infusion tubing 8, a support frame 13, and a first servo motor 15. One end of the infusion tubing 8 is connected to the inside of the outlet chamber 7. The end of the infusion tubing 8 away from the outlet chamber 7 is connected to an infusion rigid tube 9. A filling head 11 is installed at the end of the infusion rigid tube 9 away from the infusion tubing 8. A solenoid valve 10 is installed at the end of the infusion rigid tube 9 near the filling head 11. The support frame 13 is fixed to one side of the quantitative filling device 6. The first servo motor 15 is installed on the quantitative filling device 6. One end of the quantitative filling device 6 is rotatably connected to a lead screw 14 connected to the output end of the first servo motor 15. The lead screw 14 is connected to a connecting frame 12 by a lead screw nut pair. One end of the connecting frame 12 is fixed to the outer wall of the end of the infusion rigid tube 9 away from the filling head 11.

[0032] During operation, when a container needs to be filled, the conveyor belt 2 transports the container to the placement plate 3. Then, the output of the first servo motor 15 is controlled to rotate forward, which in turn drives the connecting frame 12 to move closer to the placement plate 3 via the lead screw 14. This allows the infusion tube 9 and the filling head 11 to be gradually inserted into the container. After that, the solenoid valve 10 is opened, allowing the cleaning fluid to continuously flow out from the filling head 11 to fill the container. This allows the filling head 11 to be directly inserted into the container, reducing the distance between the filling head 11 and the container. This allows the filling liquid to enter the bottle more directly and smoothly, reducing the collision between the liquid flow and the container, thus reducing the probability of air bubble formation. At the same time, the output of the first servo motor 15 is controlled to rotate in the reverse direction, causing the lead screw 14 to drive the connecting frame 12 to move away from the placement plate 3. This allows the infusion tube 9 and the filling head 11 to gradually move away from the inside of the container, reducing the contact between the liquid inside the container and the infusion tube 9 and the filling head 11, and preventing residue from adhering to their surfaces. This improves the quality of the subsequently filled products.

[0033] Example 3: Figures 1-4 As shown, the stirring assembly includes a transmission rod 16 and a rotating rod 17. One end of the rotating rod 17 is rotatably mounted on the outer wall of the storage tank 5, and the rotating rod 17 is rotatably mounted inside the storage tank 5. One end of the rotating rod 17 penetrates the interior of the storage tank 5. A first bevel gear set 18 is provided between the end of the rotating rod 17 located outside the storage tank 5 and the transmission rod 16. A pulley set 29 is provided between the end of the transmission rod 16 away from the first bevel gear set 18 and the end of the lead screw 14. Multiple sets of stirring rods 19 are installed in the area of ​​the rotating rod 17 located inside the storage tank 5.

[0034] like Figures 1-4As shown, a liquid filling pipe 20 is fixedly connected to the top of the liquid storage tank 5. A limiting ring 21 is fixedly connected to the inner wall of the liquid filling pipe 20. A filter screen 22 is movably connected to the limiting ring 21. Magnets that attract each other are provided in the contact areas between the edge of the filter screen 22 and the limiting ring 21.

[0035] During operation, when the output of the first servo motor 15 drives the lead screw 14 to rotate, the pulley group 29 can drive the transmission rod 16 to rotate accordingly. Under the transmission action of the first bevel gear group 18, the rotating rod 17 is driven to rotate, so that multiple sets of stirring rods 19 rotate inside the liquid storage tank 5 to stir the liquid inside the liquid storage tank 5, ensuring the uniformity of the internal components of the cleaning reagent, thereby improving the quality of the cleaning reagent poured into the container.

[0036] Meanwhile, when adding cleaning reagent into the storage tank 5, the filter screen 22 can filter impurities in the liquid to ensure that the liquid entering the storage tank 5 is clean. When the filter screen 22 needs to be maintained, by pulling the filter screen 22 to overcome the magnetic force of the two sets of magnets, the filter screen 22 can be quickly separated from the limiting ring 21, and the disassembly of the filter screen 22 can be completed.

[0037] Example 4: Figures 1-4 As shown, the clamping assembly includes a threaded cylinder 23 and a second servo motor 24. The threaded cylinder 23 is rotatably mounted on the base 1, and the second servo motor 24 is mounted on the base 1. A second bevel gear set 25 is provided between the output end of the second servo motor 24 and the threaded cylinder 23. The threaded cylinder 23 has internal threads through which screws 26 pass. A mounting bracket 27 is fixedly connected to the end of the screw 26 away from the threaded cylinder 23. A clamping plate 28 is fixedly connected to the end of the mounting bracket 27 away from the screw 26. The clamping plate 28 is slidably connected to the surface of the placement plate 3.

[0038] like Figures 1-4 As shown, the inner circumferential surface of the clamping plate 28 is provided with a rubber pad.

[0039] During operation, the screw cylinder 23 is driven to rotate in the forward or reverse direction by the output end of the second servo motor 24. This causes the mounting frame 27 and the clamping plate 28 to move closer or further apart through the two sets of screws 26, thereby fixing the container to be filled on the placement plate 3 and reducing the occurrence of shaking or tipping of the container during filling. At the same time, the rubber pad increases the friction of the clamping and further improves the clamping effect.

[0040] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
