Description

Technical Field

[0001] This utility model relates to the field of condiment filling technology, specifically to an automated condiment filling device with adjustable flow rate. Background Technology

[0002] Before liquid seasonings leave the factory, they need to be filled into bottles of different sizes for sale, which requires the use of filling machines.

[0003] In related technologies, a search revealed a new type of soy sauce filling machine (announcement number CN214653505U) where, when the surface of the soy sauce in the filling bottle touches the first-stage sensing ring, the electronic flow valve reduces the flow rate to prevent the soy sauce from overflowing violently due to excessive filling. When the surface of the soy sauce touches the second-stage sensing ring, the electronic flow valve closes, and then the lifting block rises until the filling tube detaches from the filling bottle.

[0004] However, the above solution controls the filling tube to detach from the filling bottle by lifting. Since there is residual seasoning in the filling tube, the residual seasoning is more likely to drip down due to inertia during the process of the filling tube rising. If it drips into the filling bottle, it needs to be cleaned up, which affects the subsequent processing steps of the filling bottle. Utility Model Content

[0005] The purpose of this invention is to provide an automated filling device for condiments with adjustable flow rate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flow rate automatic filling device for condiments, including storage tanks, wherein two storage tanks are provided and an electric valve is connected between the two storage tanks. The upper storage tank is pre-stored with a certain amount of condiments. When the electric valve is opened, the condiments flow to the lower storage tank. The lower storage tank independently fills the packaging bottles, which can quickly complete the filling process.

[0007] A filling tube is connected to a storage tank below. A baffle is rotatably connected inside the filling tube. A counterweight is provided on the upper edge of the baffle. A limiter is provided on the filling tube to restrict the rotation range of the baffle. After the seasoning has flowed out, the baffle rotates to seal the filling tube, which can prevent dripping.

[0008] An electronic flow valve is connected to the storage tank above and is connected to a liquid pump, which can quantitatively control the filling amount of the seasoning.

[0009] Furthermore, the storage tank has a connection port and two mounting ports. Both storage tanks are equipped with a first solenoid valve through the mounting ports. The first solenoid valve is open to maintain the air pressure balance of the storage tank and ensure the stable flow of the seasoning. The lower storage tank is connected to a second solenoid valve through the mounting port to control the pressurization inside the storage tank.

[0010] Furthermore, the second solenoid valve is connected to a pneumatic pump, and a gas tank is connected between the second solenoid valve and the pneumatic pump. When multiple storage tanks are used, the gas tank can provide compressed gas to all the storage tanks. The pneumatic pump pressurizes the storage tanks below, which can speed up the discharge of seasonings. The airflow flushes the filling pipe, reducing residue.

[0011] Furthermore, two fixing pins are inserted into the surface of the filling tube, and the fixing pins are rotatably connected to the connecting seat on the surface of the baffle to ensure that the baffle is installed stably and will not get stuck during rotation.

[0012] Furthermore, the limiter includes a first limit pin and a second limit pin, both of which are inserted into the filling tube. The first limit pin is located on the lower surface of the baffle, and the second limit pin is located below the baffle, ensuring that the baffle is stable within the limited range and stably performs its anti-drip function.

[0013] Furthermore, a fixing frame is connected to the storage tank, and a cylinder is connected to the fixing frame to control the lifting and lowering of the filling tube, so that the seasoning filling will not splash.

[0014] Furthermore, the lower end of the storage tank is tapered and has a threaded tube, and the filling tube has a threaded sleeve that is screwed into the threaded tube, making it convenient to replace the filling tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The baffle inside the filling tube can rotate. The condiment flows downward and pushes the baffle to rotate so that it no longer blocks the filling tube. The condiment is discharged smoothly from the filling tube. After the condiment is filled, the counterweight drives the baffle to rotate and block the filling tube. This can prevent the condiment residue in the filling tube from dripping downward and keep the bottle and production environment clean.

[0017] (2) The seasonings in the storage tank below are pressurized with gas to be discharged quickly, which improves filling efficiency. The gas flushing of the filling tube can also reduce the residue of seasonings and make the anti-dripping effect more stable.

[0018] (3) The electronic flow valve calculates the amount of seasonings being transported in the storage tank. Once the capacity reaches the target, the liquid pump stops working, which can accurately control the amount of seasonings and reduce errors. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-4 This utility model provides a technical solution: an adjustable flow rate automatic filling device for condiments, used for filling liquid condiments such as soy sauce or vinegar, including a storage tank 1, wherein two storage tanks 1 are provided, and an electric valve 7 is connected between the two storage tanks 1. The electric valve 7 blocks the two storage tanks 1 to ensure that the two storage tanks 1 do not interfere with each other. The upper storage tank 1 can pre-store a certain amount of condiments, and liquid condiments can be stored in the upper storage tank 1 in advance to prepare for the lower storage tank 1 to be replenished with condiments.

[0027] A filling tube 10 is connected to a storage tank 1 below. A baffle 12 is rotatably connected inside the filling tube 10. A counterweight 14 is provided on the upper edge of the baffle 12. A limiter is provided on the filling tube 10 to limit the rotation range of the baffle 12. When no seasoning impacts the baffle 12, the counterweight 14 drives the baffle 12 to rotate, so that the baffle 12 blocks the filling tube 10. The small amount of seasoning remaining on the inner wall of the filling tube 10 is not easy to drip down, avoiding the presence of seasoning on the surface of the packaging bottle, eliminating the need to clean the bottle, and reducing unnecessary steps.

[0028] Electronic flow valve 5 is equipped with a liquid flow meter. Liquid seasonings flow through the liquid flow meter. The filling volume is determined by measuring the flow rate and time of the seasonings. Electronic flow valve 5 is connected to the storage tank 1 above. Electronic flow valve 5 is also connected to a liquid pump 6. Liquid pump 6 draws seasonings through electronic flow valve 5 and delivers them to storage tank 1. Electronic flow valve 5 closes after detecting that the seasoning flow rate meets the standard. At the same time, liquid pump 6 is turned off, thereby controlling the seasoning capacity.

[0029] In this embodiment, as Figure 1 As shown, the storage tank 1 has a connection port 4 and two mounting ports 3. Both storage tanks 1 are equipped with a first solenoid valve 2 through the mounting ports 3. The first solenoid valve 2 maintains the air pressure balance of the storage tank 1, ensuring that the seasonings flow smoothly into and out of the storage tank 1. The lower storage tank 1 is connected to a second solenoid valve 9 through the mounting ports 3. The second solenoid valve 9 can control the pressure inside the lower storage tank 1.

[0030] In this embodiment, as Figure 1 As shown, the second solenoid valve 9 is connected to a pneumatic pump 8. When only one set of upper and lower storage tanks 1 is used, the pneumatic pump 8 can be used to directly pressurize the storage tank 1 to increase the discharge speed of the seasoning. The pressure range is controlled between 0.1-0.3 MPa, and the pressurization time is determined according to the packaging bottle. When about 90% of the seasoning in the storage tank 1 is discharged, the pressurization is stopped, which can control the stable discharge of the seasoning. The packaging bottle has a certain amount of extra space, and the filling tube 10 is slightly inserted into the bottle mouth to avoid gas impacting the seasoning inside the packaging bottle.

[0031] In this embodiment, as Figure 2 As shown, two fixing pins 11 are inserted into the surface of the filling tube 10. The fixing pins 11 are rotatably connected to the connecting seat 15 on the surface of the baffle 12, so as to realize the rotational installation state of the baffle 12 inside the filling tube 10, ensuring that the baffle 12 rotates stably and will not have any jamming problems.

[0032] In this embodiment, as Figure 2 and Figure 3 As shown, the limiter includes a first limit pin 13 and a second limit pin 16. Both the first limit pin 13 and the second limit pin 16 are inserted into the filling tube 10. The first limit pin 13 is located on the lower surface of the baffle 12. When the counterweight 14 drives the baffle 12 to rotate, the first limit pin 13 keeps the baffle 12 in a horizontal state. The second limit pin 16 is located below the baffle 12 and is a certain distance away from the baffle 12, so that the baffle 12 can rotate at a certain angle, but will not rotate excessively. When no seasoning impacts the baffle 12, the baffle 12 quickly returns to a horizontal state.

[0033] In this embodiment, as Figure 4As shown, a fixing frame 19 is connected to the storage tank 1, and a cylinder 18 is connected to the fixing frame 19. The fixing frame 19 can fix several sets of storage tanks 1 together. The cylinder 18 controls the lifting and lowering of the storage tank 1 and the filling tube 10 through the fixing frame 19, so that the filling tube 10 can be inserted into the packaging bottle to avoid splashing.

[0034] In this embodiment, as Figure 4 As shown, a gas tank 17 is connected between the second solenoid valve 9 and the air pump 8. When there are many storage tanks 1, compressed gas can be stored in the gas tank 17 through the air pump 8, which makes it convenient to pressurize each storage tank 1. A filter can be set before the air inlet of the air pump 8 to reduce the amount of impurities entering the storage tank 1.

[0035] In this embodiment, as Figure 1 As shown, the lower end of the storage tank 1 is tapered and has a threaded tube 20. The filling tube 10 has a threaded sleeve 21 that is screwed into the threaded tube 20. The filling tube 10 can be quickly replaced by unscrewing the threaded sleeve 21.

[0036] Specifically, the control logic of the first solenoid valve 2, electronic flow valve 5, liquid pump 6, electric valve 7, and second solenoid valve 9 is as follows, using a PLC system or microcontroller for control: During the initialization phase, the two first solenoid valves 2 are opened, the liquid pump 6 and electronic flow valve 5 are started, the volume of seasoning in milliliters is detected, and the liquid pump 6 and electronic flow valve 5 are closed after the target is reached.

[0037] During the seasoning transfer stage, the electric valve 7 is opened, and the seasoning is transferred from the upper storage tank 1 to the lower storage tank 1. The electric valve 7 and the lower first solenoid valve 2 are then closed.

[0038] During the seasoning replenishment stage, start the liquid pump 6 and electronic flow valve 5 to replenish the seasoning to the upper storage tank 1;

[0039] During the filling stage, cylinder 18 controls the filling tube 10 to be inserted into the packaging bottle, and the second solenoid valve 9 is opened for a specified time. Compressed air enters the storage tank 1, and the seasoning is forced into the filling tube 10 and into the packaging bottle.

[0040] When filling liquid seasoning, the two first solenoid valves 2 are opened to ensure the air pressure balance between the upper and lower storage tanks 1. The liquid pump 6 draws the seasoning and sends it into the upper storage tank 1 through the electronic flow valve 5. The electronic flow valve 5 detects the amount of seasoning. When the amount of seasoning reaches the standard, the electronic flow valve 5 and the liquid pump 6 are closed, and the electric valve 7 is opened for a specified time. At this time, the seasoning in the upper storage tank 1 falls into the lower storage tank 1. After all the seasoning has fallen into the lower storage tank 1, the electric valve 7 and the lower first solenoid valve 2 are closed, and the liquid pump 6 and the electronic flow valve 5 are started to replenish the upper storage tank 1 with seasoning.

[0041] The packaging bottle is conveyed to the bottom of the filling tube 10 by the conveyor. The cylinder 18 controls the filling tube 10 to be inserted into the bottom of the bottle opening. The second solenoid valve 9 opens for a specified time, and the compressed air in the gas tank 17 enters the storage tank 1. The pressure in the storage tank 1 increases, and the seasoning is forced into the filling tube 10. The seasoning impacts the baffle 12, and the baffle 12 rotates to no longer block the filling tube 10. The seasoning enters the packaging bottle. The compressed gas can also flush the filling tube 10 and the baffle 12 to reduce the residue of the seasoning. After the seasoning is drained, the cylinder 18 controls the filling tube 10 to separate from the packaging bottle. The counterweight 14 drives the baffle 12 to rotate and block the filling. During the upward movement of the filling tube 10, no seasoning drips.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
