[0002] Bottle cleaner is a cleaning agent used to clean the surface of containers such as glass bottles and plastic bottles. It is mainly used to remove stains, grease and microbial residues, thereby ensuring that the containers are clean and hygienic.

[0003] The core components of bottle washing agents mainly include surfactants, acid and alkali reagents, organic solvents, and additives. Some of these components are liquids, while others are granular or powdered solids. During the production process, these components need to be mixed together, and various mixing tanks are commonly used to mix them.

[0004] For example, a raw material mixing tank disclosed in patent CN220443579U uses two mutually perpendicular rotating shafts to stir the raw materials. The sleeve and rotating rod move synchronously, and the rotation of the rotating rod achieves superimposed motion, so that the raw materials are stirred more thoroughly in two axes, thereby improving the mixing effect.

[0005] Although the mixing tank can fulfill basic mixing functions, it cannot precisely control the amount of various materials added. Workers need to pre-mix the raw materials and then pour them into the tank, resulting in low efficiency and requiring further improvement. Utility Model Content

The feeding assembly is located on the cover and on one side of the shut-off valve. The screw feeder is located on one side of the tank body. The tank body has a discharge port at the bottom.

[0008] Furthermore, the feeding assembly includes a base, a weighing sensor, a feeding hopper, a baffle plate, and a cylinder. The four corners of the bottom of the base are connected to the top of the cover through the weighing sensor. The feeding hopper is set on the base and its bottom discharge port is connected to the tank. The baffle plate is set horizontally at the discharge port. The cylinder is set on the base and is connected to the baffle plate in a transmission manner.

[0009] Furthermore, a sealing ring is provided at the position where the material discharge port movably engages with the baffle plate.

[0010] Furthermore, the discharge port of the screw feeder is located above the feed hopper, and a discharge valve is provided at the discharge port.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0022] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 As shown, the bottle washing agent mixing tank with precise controllable feed amount in this embodiment includes a tank body 1, a cover body 2, a stirrer 3, a drive motor 4, a shut-off valve 5, a flow meter 6, a feeding assembly 7, and a screw feeder 8. The tank body 1 and the screw feeder 8 are arranged adjacent to each other and are supported on the ground by support legs 9 and brackets 10, respectively.

[0024] The cover 2 is located at the top opening of the tank 1. The cover 2 and the tank 1 can be connected by a hinged connection commonly used in the art, so as to open the cover 2 and clean and maintain the inside of the tank 1.

[0025] The agitator 3 is inserted obliquely into the tank 1 from above the cover 2. The drive motor 4 is fixedly installed on the top of the cover 2 and is connected to the agitator 3. The drive motor 4 drives the agitator 3 to rotate, which can stir and mix the materials inside the tank 1.

[0026] The shut-off valve 5 is fixedly mounted on the cover 2 and communicates with the inside of the tank 1. The flow meter 6 is located at the inlet end of the shut-off valve 5, and the two are connected by an electrical signal. The shut-off valve 5 can be a commonly used electric or pneumatic shut-off valve in the art, preferably a pneumatic shut-off valve, such as the ZJQP series pneumatic diaphragm standard single-seat shut-off valve, which can cut off the material flow within 0.2-0.5s. The flow meter 6 can be an LDG-MIK series electromagnetic flow meter, which can accurately measure the feed rate of the material and feed the flow signal back to the actuator of the shut-off valve 5.

[0027] The feeding assembly 7 is set on the cover 2 and located on one side of the shut-off valve 5. The screw feeder 8 is set on one side of the tank 1 and is used to convey granular or powdery materials to the feeding assembly 7. The bottom of the tank 1 is also provided with a discharge port 11. A discharge valve can be set on the discharge port 11, and the mixed materials are discharged from the discharge port 11.

[0028] The outer wall of the tank 1 is provided with an insulation layer 12, and an insulation cavity 13 is formed between the insulation layer 12 and the outer wall of the tank 1. The insulation layer 12 can be filled with thermal insulation materials such as rock wool and foam plastic. The insulation cavity 13 has a water inlet 14 on one side of the upper end and a water outlet 15 on one side of the lower end. A temperature sensor 16 is provided at the bottom of the tank 1. The temperature sensor 16 can be a CWDZ11A series temperature sensor, and its probe extends into the interior of the tank 1.

[0029] Some materials have requirements for reaction temperature. Hot water can be introduced into the insulation chamber 13 through the water inlet 14, and the temperature can be monitored in real time through the temperature sensor 16.

[0030] like Figure 2 As shown, the feeding assembly 7 includes a base 71, a weighing sensor 72, a feeding hopper 73, a baffle plate 74, and a cylinder 75. The four corners of the bottom of the base 71 are connected to the top of the cover 2 through the weighing sensor 72, and the four weighing sensors 72 are connected in series to form a full-bridge circuit. The feeding hopper 73 is set on the base 71 and its bottom discharge port is connected to the tank 1. The baffle plate 74 is set horizontally at the discharge port. The cylinder 75 is set on the base 71 and is connected to the baffle plate 74 in a driving connection. A sealing ring is provided at the position where the discharge port moves and cooperates with the baffle plate 74. For example, the sealing ring can be set at the position where the discharge port contacts the upper and lower surfaces and the perimeter of the baffle plate 74. This can ensure that the baffle plate 74 will not carry the material out of the feeding hopper 73 during the reciprocating motion.

[0031] The feeding assembly 7 is connected to the tank 1 only through the weighing sensor 72. In this way, when the material enters the feeding hopper 73, the gross weight of the material can be accurately measured. After subtracting the weight of the base 71, the feeding hopper 73, the baffle plate 74 and the cylinder 75, the net weight of the material is obtained.

[0032] The discharge port of the screw feeder 8 is located above the feed hopper 73, and a discharge valve 81 is provided at the discharge port.

[0033] Among them, the weighing sensor 72 can be a resistance strain gauge pressure sensor, which has the advantages of small error (usually less than 1%) and wide measurement range; the cylinder 75 can be a rodless cylinder, which has the advantage of small axial space occupation; the unloading valve 81 can be a Herlmann pneumatic powder butterfly valve, which is designed for powdery or granular materials and has the advantages of wear resistance and good sealing performance.

[0034] The shut-off valve 5, flow meter 6, weighing sensor 72, cylinder 75, and unloading valve 81 are all connected to the equipment's PLC via electrical signals. Control and linkage of each component are achieved through PLC programming. The system architecture is as follows: I. Hardware Configuration and I / O Allocation 1. Input devices: I0.0: Flow meter pulse signal (liquid material); I0.1: System Start Button; I0.2: System Stop Button; I0.3: Emergency Stop Button; I0.4: Peel button; AIW0: Analog input to the weighing sensor (granular or powdery materials).

[0035] 2. Output devices: Q0.0: Shut-off valve control (liquid materials); Q0.1: Discharge valve control (for granular or powdery materials); Q0.2: Cylinder control (for granular or powdery materials); Q0.3: Feeding control (screw feeder).

[0036] II. Control Program Logic 1. Main program control flow Press the start button (I0.1) and the system will enter the running state; Press the stop button (I0.2) or the emergency stop button (I0.3) and the system will stop immediately; The system's operating status is controlled by the System_Active flag.

[0037] 2. Liquid material feed control 2.1-Flow Monitoring: The pulse counter increments by 1 for each pulse signal (I0.0) generated by the flow meter; Convert the number of pulses to the actual flow rate (e.g., 1 pulse = 0.1L). Calculate and update the cumulative traffic value in real time.

[0038] 2.2 Valve Control Logic: When the system is running and the cumulative flow is less than the target set value, the shut-off valve (Q0.0) is opened. When the cumulative flow reaches or approaches the target set value: Set a valve closed status indicator; Adjust or close the shut-off valve (Q0.0); The accumulated flow rate value is automatically reset when the system stops.

[0039] 3. Feed control of particulate materials 3.1 Weight Monitoring: Real-time reading of analog values ​​from the weighing sensor (AIW0); Convert the analog values ​​to actual weight values ​​(0-27648 corresponds to 0-1000kg). Calculate net weight: Net weight = Gross weight - Tare weight.

[0040] 3.2 Valve Control Logic: When the system is running and the current net weight is less than the target weight, open the unloading valve (Q0.1) and cylinder (Q0.2). When the current net weight reaches or approaches the target weight: Set a valve closed status indicator; Adjust or close the discharge valve (Q0.1); Close cylinder (Q0.2).

[0041] 3.3 Feeding control logic: When the current net weight reaches or approaches the target weight: The screw feeder stops or slows down.

[0042] 3.4 - Peeling function: When the tare button (I0.4) is pressed, the current weight is set as the tare value.

[0043] 4. Safety protection functions When the emergency stop button (I0.3) is pressed: Immediately close all valves (stop valve, discharge valve, and cylinder); Stop the system from running; A manual reset is required before restarting.

[0044] The working principle of this utility model will be explained below in conjunction with the above control logic: First, a suitable amount of liquid raw material is added into tank 1 through shut-off valve 5 and flow meter 6. During the addition process, flow meter 6 monitors the liquid flow rate in real time. When the flow rate approaches the preset value, flow meter 6 sends a signal to shut-off valve 5. The actuator of shut-off valve 5 first reduces the valve opening angle, thus reducing the flow rate. When the preset flow rate is reached, shut-off valve 5 immediately actuates, cutting off the material flow within 0.2-0.5 seconds. Since the flow rate has been reduced at this time, the excess material flowing out is still within an acceptable error range.

[0045] The powdery or granular material is then lifted into the feed hopper 73 by the screw feeder 8 and falls onto the baffle plate 74. At this time, the weighing sensor 72 will detect the weight of the material in real time. When it approaches the preset weight value, the screw feeder 8 slows down and adjusts the valve opening angle of the discharge valve 81 to reduce the feed rate. When the preset flow rate is reached, the discharge valve 81 immediately closes to cut off the material flow. Since the feed rate has been reduced at this time, the excess material flowing out is still within an acceptable error range.

[0046] After the material is discharged, the cylinder 75 is activated to pull out the baffle plate 74, allowing the material to enter the tank 1 through the discharge port of the feed hopper 73. Then the cylinder 75 drives the baffle plate 74 to reset.

[0047] In summary, the mixing tank of this utility model monitors the feed rate of liquid materials in real time through the flow meter 6 and stops the feed through the shut-off valve 5. It also monitors the feed rate of solid materials in real time through the feeding assembly 7 and stops the feed in time through the screw feeder 8. This achieves precise control of the feed rate of various materials, thereby saving manual batching time and improving the production efficiency of bottle washing agents.

[0048] It should be noted that the “precise” control of the feed amount mentioned in this embodiment does not mean that the actual feed amount is completely consistent with the preset feed amount, but only within a reasonable error range, because even if the feed amount is weighed manually, there will inevitably be errors; the components in this embodiment are not limited to the models listed above, and other models that can achieve the same function are also acceptable.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
