[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, most existing spraying devices use traditional spraying methods to spray plasticizers. Since traditional spraying devices have difficulty in quantitatively controlling the amount of plasticizer sprayed, it may be difficult to control the amount of plasticizer sprayed. Therefore, those skilled in the art have provided a plasticizer quantitative spraying device to solve the problems mentioned in the background art. Utility Model Content

At the same time, the quantitative box is equipped with a floating block and an adjusting plate, which can control the liquid dosage inside the quantitative box after adjustment. The electric telescopic rod can drive the spraying plate to spray at different heights.

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

[0015] 1. This utility model proposes a plasticizer metering spraying device, which uses metering boxes to be snapped onto the upper end face of the base plate near the front end. An adjusting rod can be movably embedded in the upper end face of the metering box near the front end. After a floating block is installed on the lower end face of the adjusting rod, liquid can be injected into the metering box. The gradually rising water level drives the floating block to rise and fall, and at the same time, it can drive the adjusting plate to rise and fall. After the adjusting plate is threaded onto the outer surface of the adjusting rod, the rotating adjusting rod can drive the adjusting plate to adjust its height. At the same time, a trigger controller is embedded in the inner top surface of the metering box, and a trigger block is embedded in the upper end face of the adjusting plate. When the floating block drives the adjusting plate to rise and fall to a certain height, the trigger block and the trigger controller can be engaged, thereby generating a signal to control the solenoid valve and control the flow rate of liquid into the metering box.

[0025] 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.

[0026] Reference Figures 1 to 6A plasticizer metering spraying device includes a base plate 1, a storage box 3 is provided on the upper end face of the base plate 1 near the rear end, metering boxes 2 are provided on both sides of the upper end face of the base plate 1 near the front end, an adjusting rod 8 is provided at the midpoint of the upper end face of the two metering boxes 2 near the front end, a floating block 15 is provided on the lower end face of the two adjusting rods 8, and an adjusting plate 13 is provided on the lower end of the outer surface of the two adjusting rods 8.

[0027] A fixed seat 17 is fixedly installed on both sides of the upper end face of the base plate 1. An electric telescopic rod 6 is fixedly installed on the upper end face of the two fixed seats 17. An installation plate 9 is fixedly installed on the upper end face of the two electric telescopic rods 6. A spray plate 16 is snapped onto the upper end face of the two installation plates 9. A water pump 5 is snapped onto the rear end side of the upper end face of the two metering tanks 2.

[0028] Specifically, after a storage tank 3 is installed on the upper surface of the base plate 1, the plasticizer to be used can be stored. A water inlet is installed on the upper surface of the storage tank 3, through which the plasticizer can be better injected into the storage tank 3 for storage. After a metering tank 2 is snapped on both sides of the front end of the upper surface of the base plate 1, the plasticizer to be sprayed can be delivered in a fixed and regulated manner. After a floating block 15 is installed inside the metering tank 2, an adjusting rod 8 can be rotatably installed on the upper surface of the floating block 15. After an adjusting plate 13 is threaded on the outer surface of the adjusting rod 8, the rotating adjusting rod 8 can drive the adjusting plate 13 to move up and down on the outer surface of the adjusting rod 8. At the same time, plasticizer is injected into the metering tank 2. After the agent is applied, the floating block 15 can float on the surface of the liquid. When the liquid level rises, it can drive the floating block 15 to rise. At the same time, the floating block 15 can also drive the adjusting plate 13 to rise. After the fixing seats 17 are fixed on both sides of the upper end face of the base plate 1, the electric telescopic rod 6 can be installed and fixed on the upper end face of the fixing seat 17. At the same time, the mounting plate 9 is fixed on the upper end face of the electric telescopic rod 6, and the spraying plate 16 can be snapped and fixed on the upper end face of the mounting plate 9. The water pump 5 is snapped and fixed on the upper end face of the metering tank 2. After the water pump 5 is connected to the spraying plate 16 using the telescopic hose 10, the water pump 5 can extract the plasticizer in the metering tank 2 and spray it through the spraying plate 16.

[0029] Reference Figure 4 and Figure 5 Two adjusting rods 8 are embedded in the bottom surface of the metering box 2 at their lower ends. Two adjusting plates 13 are threaded onto the outer surfaces of the two adjusting rods 8 respectively. The upper ends of the two adjusting rods 8 are movably inserted through the upper surface of the metering box 2. Limiting plates are fixedly installed at the front end of the two metering boxes 2. Two floating blocks 15 and two adjusting plates 13 are movably fitted onto the outer surfaces of the two limiting plates respectively.

[0030] Specifically, after a limiting plate is fixedly installed inside the metering tank 2, the rear ends of the floating block 15 and the adjusting plate 13 can be movably fitted onto the outer surface of the limiting plate, thereby allowing the floating block 15 and the adjusting plate 13 to move up and down more effectively. After the adjusting plate 13 is threaded onto the outer surface of the adjusting rod 8, the rotating adjusting rod 8 can drive the adjusting plate 13 to move up and down. Simultaneously, under the action of the limiting plate, the rotating adjusting rod 8 drives the adjusting plate 13 to rotate synchronously. Furthermore, the floating block 15 has a hollow internal structure, ensuring that it always floats above the liquid. When the liquid inside the metering tank 2 rises, it can drive the floating block 15 to move up and down. At the same time, the adjusting rod 8 and the adjusting plate 13 can also be driven to move up and down. The adjusting rod 8 is set to move through the upper end surface of the metering tank 2. After the adjusting rod 8 moves up and down, it will not be affected by the upper end surface of the metering tank 2. After rotating the adjusting rod 8 to adjust the height of the adjusting plate 13, the distance between the trigger block 14 and the trigger controller 12 set on the upper end surface of the adjusting plate 13 can be reduced, thereby controlling the liquid height inside the metering tank 2.

[0031] Reference Figure 5 Both adjustment plates 13 have trigger blocks 14 embedded on their upper surfaces near the rear end, and both quantitative boxes 2 have trigger controllers 12 embedded on their inner top surfaces near the midpoint of the front end.

[0032] Specifically, after the trigger block 14 is embedded in the upper surface of the regulating plate 13, the trigger controller 12 can be embedded in the inner top surface of the metering box 2. At the same time, the trigger block 14 and the trigger controller 12 are in the same position. After the floating block 15 drives the regulating plate 13 to rise, it can drive the trigger block 14 and the trigger controller 12 to fit together, so that the trigger controller 12 can generate an electrical signal to control the solenoid valve 7. Both the trigger block 14 and the trigger controller 12 adopt existing known technical solutions. The trigger controller 12 is equipped with a power supply, which can provide power to the trigger controller 12.

[0033] Reference Figure 3 and Figure 4 Drain pipes 11 are provided between one side of the upper end face of the two quantitative tanks 2 and both sides of the front end face of the storage tank 3, and solenoid valves 7 are snapped into the two drain pipes 11.

[0034] Specifically, after installing a drain pipe 11 between the two metering tanks 2 and the storage tank 3, the drain pipe 11 can connect the metering tank 2 and the storage tank 3, thereby transporting the liquid in the storage tank 3 to the metering tank 2. A solenoid valve 7 is installed in the drain pipe 11, and the flow rate of the liquid can be controlled by the solenoid valve 7. At the same time, the electrical signal generated when the trigger controller 12 and the trigger block 14 come into contact can be transmitted to the solenoid valve 7, thereby controlling the solenoid valve 7 to open or close.

[0035] Reference Figure 4 and Figure 6 Both water pumps 5 are equipped with suction pipes 18 at their rear ends. The two suction pipes 18 are embedded inside the metering tank 2. Both water pumps 5 are equipped with telescopic hoses 10 on their upper surfaces. The ends of the two telescopic hoses 10 away from the water pumps 5 are respectively connected to the two spray plates 16.

[0036] Specifically, after installing a suction pipe 18 at the rear end of the water pump 5, the suction pipe 18 can be embedded inside the metering tank 2. At the same time, the water pump 5 can be connected to the spray plate 16 using a telescopic hose 10. After starting the water pump 5, the liquid in the metering tank 2 can be extracted and sprayed out through the snap-fit ​​spray plate 16. The telescopic hose 10 can better connect the spray plate 16 and the water pump 5.

[0037] Reference Figure 1 and Figure 2 Storage box 3 is snapped into the upper end face of the base plate 1 near the rear end. Two quantitative boxes 2 are snapped into the upper end face of the base plate 1 near the front side on both sides. Universal wheels 4 are fixedly installed on both sides of the lower end face of the base plate 1 near the front and rear ends.

[0038] Specifically, after the storage box 3 and the metering box 2 are snapped onto the upper surface of the base plate 1, casters 4 can be fixedly installed on the lower surface of the base plate 1, so that the spraying equipment can be moved more conveniently, making the use of the spraying equipment more convenient. At the same time, the casters 4 are self-locking casters, which can effectively ensure the stability of the equipment after it stops moving.

[0039] Working principle: During use, the operator can deliver plasticizer into the storage tank 3 through the water inlet at the top of the storage tank 3. After connecting the storage tank 3 and the metering tank 2 through the drain pipe 11, the injected plasticizer can also be delivered into the metering tank 2. As the liquid level in the metering tank 2 gradually rises, the floating block 15 and the adjusting plate 13 set inside the metering tank 2 can be driven to rise and fall. After the trigger block 14 and the trigger controller 12 are attached, the electrical signal generated in the trigger controller 12 can control the solenoid valve 7 set in the drain pipe 11, thereby closing the solenoid valve 7. After the water pump 5 is started, the plasticizer inside the metering tank 2 can be extracted and sprayed out through the spray plate 16. After the liquid in the metering tank 2 is completely extracted, the solenoid valve 7 can be opened through the external controller to allow the plasticizer in the storage tank 3 to be discharged into the metering tank 2 for spraying out.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
