[0002] Resin paint refers to coatings made primarily of synthetic resin, with the addition of solvents, fillers, additives, and other modifiers. During the addition of additives, the additives may react violently with the resin paint, thus requiring the use of a dripping device for addition.

[0003] A Chinese patent with authorization announcement number CN 219615359 U discloses a resin paint additive dripping device, including a mixing hopper. A motor is fixedly connected to the top center of the mixing hopper. Injection ports are fixedly connected to both sides of the top of the mixing hopper. A limit block is rotatably connected to the bottom side wall of the mixing hopper. A discharge plug is slidably connected to the other side wall of the bottom of the mixing hopper. A discharge port is fixedly connected to the bottom center of the mixing hopper. A heating element is fixedly connected to the inner side wall of the mixing hopper. A stirring device is rotatably connected to the top of the inner side wall of the mixing hopper. The stirring device includes a stirring shaft, and several stirring blades are arrayed on the side wall of the stirring shaft. This invention provides a resin paint additive dripping device that uses a stirring device in the mixing hopper to ensure more thorough mixing of the additives, and uses a heating element on the side wall of the mixing hopper to effectively prevent the additives from adhering to the inner side wall of the mixing hopper.

[0004] Existing dripping devices struggle to precisely control the amount of additives added during the dripping process of resin paint. Too much or too little additive will affect the viscosity of the resin paint, resulting in poor accuracy in the amount of additive added and affecting the quality of the resin paint. Therefore, a resin paint additive dripping device is proposed to address the above problems. Utility Model Content

A first guide pipe is installed on the bottom side of the storage tank, and a first solenoid valve is installed on the first guide pipe. The first guide pipe is connected to a fixed cylinder. A second guide pipe is installed on the bottom side of the weighing hopper, and a second solenoid valve is installed on the second guide pipe. The first electrode plate and the second electrode plate are connected to an indicator light through an internal circuit. The indicator light is connected to a control panel through an internal circuit. The control panel is connected to the first solenoid valve and the second solenoid valve through an internal circuit. The additives in the storage tank flow from the first guide pipe into the weighing hopper, increasing the overall weight of the weighing hopper. The weighing hopper drives the first lifting plate to move vertically downward, and the first lifting plate drives the first electrode plate to move vertically downward until the first electrode plate contacts the second electrode plate. At the instant, the first solenoid valve on the first guide pipe closes, achieving accurate weighing of the additives. This structure allows for precise control of the amount of additives added as needed, which is beneficial for improving the accuracy of additive addition and the quality of resin paint.

[0007] Preferably, a third guide pipe is installed on the top plate of the cylinder, and a second guide pipe is placed inside the third guide pipe. A sphere is rotatably installed on the inner wall of the third guide pipe, and a material passage hole is opened in the sphere.

A discharge pipe is installed on the bottom side of the cylinder, and a valve is installed on the discharge pipe. Equipped with temperature and pressure sensors connected to the control panel via internal circuitry, the additives flow into the third feed tube. A first motor drives a continuously rotating ball, causing the additives to drip into the resin paint through the ball's feed hole, thus achieving additive addition. A stirring rod agitates the resin paint and additives, ensuring uniform mixing. Simultaneously, the internal temperature and pressure sensors detect the internal temperature and pressure, adjusting the additive dripping rate accordingly. This structure controls the additive dripping rate, maintaining a stable mixture and improving the device's usability.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes the process where the additives in the storage tank flow from the first feed pipe into the weighing hopper, increasing the overall weight of the weighing hopper. The weighing hopper then drives the first lifting plate to move vertically downwards, which in turn drives the first electrode plate to move vertically downwards. At the moment the first electrode plate contacts the second electrode plate, the first solenoid valve on the first feed pipe closes, thus achieving precise weighing of the additives. This structure allows for precise control of the amount of additives added as needed, which is beneficial for improving the accuracy of additive addition and thus improving the quality of resin paint.

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 scope of protection of the present utility model.

[0019] Please see Figure 1-3As shown, a resin paint additive dripping device includes a base 1, a cylinder 2 mounted on the base 1 via a bracket, a control panel 3 mounted on the outer wall of the cylinder 2, a bracket 4 mounted on the base 1, a fixed cylinder 8 mounted on the bracket 4, a weighing hopper 9 slidably connected to the inner wall of the fixed cylinder 8, multiple sets of springs 12 installed between the bottom side of the weighing hopper 9 and the bottom plate of the fixed cylinder 8, a lifting groove 13 opened on the side wall of the fixed cylinder 8, a first lifting plate 14 and a second lifting plate 15 assembled in the lifting groove 13, and a first lifting plate 14 and a second lifting plate 15 installed on the bottom side of the first lifting plate 14. Electrode 16, second electrode 17 is mounted on the top side of the second lifting plate 15, indicator light 18 is mounted on the outer wall of the fixed cylinder 8, the first lifting plate 14 is fixedly connected to the side wall of the weighing hopper 9, two fixing blocks 19 are mounted on the outer wall of the fixed cylinder 8, screws 20 are rotatably mounted on the two fixing blocks 19, and knobs are mounted on the screws 20, the second lifting plate 15 is sleeved on the screws 20, scale lines 21 are provided on the outer wall of the fixed cylinder 8, a storage box 5 is mounted on the bracket 4, and a first guide pipe 6 is mounted on the bottom side of the storage box 5. A first solenoid valve 7 is installed on the feed pipe 6, and the first feed pipe 6 is connected to the fixed cylinder 8. A second feed pipe 10 is installed on the bottom side of the weighing hopper 9, and a second solenoid valve 11 is installed on the second feed pipe 10. The first electrode plate 16 and the second electrode plate 17 are connected to the indicator light 18 through an internal circuit. The indicator light 18 is connected to the control panel 3 through an internal circuit. The control panel 3 is connected to the first solenoid valve 7 and the second solenoid valve 11 through an internal circuit. During operation, the existing dripping device has difficulty in accurately controlling the amount of additives added during the dripping of additives into the resin paint. Too much or too little additive will affect the viscosity of the resin paint, resulting in poor accuracy of the additive addition and affecting the quality of the resin paint. By turning the knob, the screw 20 is driven to rotate. The screw 20 drives the second lifting plate 15 on it to move vertically. The second lifting plate 15 drives the second electrode plate 17 to move vertically. The value on the scale line 21 is the additive addition value. The position of the second lifting plate 15 is precisely adjusted according to the scale line 21, thereby achieving precise control of the additive addition.

[0020] Then, the control panel 3 controls the operation of the first solenoid valve 7. The additives in the storage tank 5 flow from the first guide pipe 6 into the weighing hopper 9. The overall weight of the weighing hopper 9 increases, and the weighing hopper 9 moves vertically downward, pressing the spring 12. At the same time, the weighing hopper 9 drives the first lifting plate 14 to move vertically downward. The first lifting plate 14 drives the first electrode plate 16 to move vertically downward until the first electrode plate 16 contacts the second electrode plate 17. At the moment of contact, the internal circuit structure of the indicator light 18 sends an electrical signal to the control panel 3. After receiving the electrical signal, the control panel 3 controls the first solenoid valve 7 on the first guide pipe 6 to close, realizing the accurate weighing of the additives. This structure can accurately control the amount of additives added as needed, which is beneficial to improving the accuracy of the amount of additives added and improving the quality of the resin paint.

[0021] Please see Figure 4-5 As shown, a third guide pipe 22 is installed on the top plate of the cylinder 2, and a second guide pipe 10 is placed inside the third guide pipe 22. A sphere 23 is rotatably installed on the inner wall of the third guide pipe 22, and a material passage hole 24 is opened in the sphere 23. A first motor 25 is installed on the top plate of the cylinder 2 via a base, and the output shaft of the first motor 25 is fixedly connected to the rotating shaft on the sphere 23. A drive motor 26 is installed on the top plate of the cylinder 2 via a base, and a stirring rod 27 is installed on the output shaft of the drive motor 26. A feed pipe 28 is installed on the top plate of the cylinder 2, and a cover 29 is installed on the feed pipe 28. A discharge pipe 30 is installed on the bottom side of the cylinder 2, and a valve is installed on the discharge pipe 30. A temperature sensor and a pressure sensor are installed on the inner wall of the cylinder 2. Force sensor, temperature sensor and pressure sensor are connected to control panel 3 through internal circuit; during operation, the existing dripping device is difficult to keep the mixture in a stable state during the dripping of additives into resin paint, and is prone to violent reactions, resulting in poor usability of the device. By pouring resin paint into the feed pipe 28, and then controlling the second solenoid valve 11 on the second guide pipe 10 to open through control panel 3, the additive in the weighing hopper 9 flows into the third guide pipe 22. Control the first motor 25 to operate through control panel 3. The first motor 25 drives the ball 23 to rotate continuously. During the rotation of the ball 23, the additive will drip from the feed hole 24 of the ball 23 into the resin paint, realizing the dripping of the additive;

[0022] When resin paint and additives react, phenomena such as exothermic reaction, gas release and unstable mixing occur. During this process, the drive motor 26 is operated to drive the stirring rod 27 to rotate. The stirring rod 27 stirs the resin paint and additives, thus achieving uniform mixing of the mixture.

[0023] Meanwhile, the temperature and pressure sensors inside cylinder 2 detect the internal temperature and air pressure. The temperature sensor is a dd1850 and the pressure sensor is an MPXV5004. The temperature and pressure sensors send the detected data to control panel 3 in real time. If the temperature and air pressure are high, it indicates that the additive is dripping too fast. At this time, the control system inside control panel 3 will control the rotation speed of the first motor 25 shaft to slow it down, thereby slowing down the additive dripping speed. This structure can control the dripping speed of the additive, so that the mixing is in a stable state, which is beneficial to improving the usability of the device.

[0024] Working principle: Existing dripping devices struggle to precisely control the amount of additives added during the dripping of resin paint. Too much or too little additive will affect the viscosity of the resin paint, resulting in poor accuracy in additive addition and impacting the quality of the resin paint. By rotating a knob, the screw 20 rotates, causing the second lifting plate 15 on it to move vertically. The second lifting plate 15 then moves the second electrode plate 17 vertically. The value on the scale 21 indicates the amount of additive added. By precisely adjusting the position of the second lifting plate 15 according to the scale 21, precise control of the additive addition amount is achieved. Subsequently, the control panel 3 controls the operation of the first solenoid valve 7, allowing the additive in the storage tank 5 to flow from the first guide pipe 6 to... Inside the weighing hopper 9, the overall weight of the weighing hopper 9 increases, causing it to move vertically downwards and press the spring 12. Simultaneously, the weighing hopper 9 drives the first lifting plate 14 to move vertically downwards, which in turn drives the first electrode plate 16 to move vertically downwards until the first electrode plate 16 contacts the second electrode plate 17. At the instant the first electrode plate 16 contacts the second electrode plate 17, the internal circuit structure of the indicator light 18 sends an electrical signal to the control panel 3. Upon receiving the signal, the control panel 3 controls the first solenoid valve 7 on the first feed pipe 6 to close, achieving precise weighing of the additives. This structure allows for precise control of the amount of additives added as needed, improving the accuracy of additive addition and thus the quality of the resin paint. Existing drip-feeding methods... During the process of adding additives to resin paint, it is difficult to maintain a stable mixture, which can easily lead to violent reactions and poor usability of the device. Resin paint is poured into the feed pipe 28, and then the second solenoid valve 11 on the second feed pipe 10 is opened via the control panel 3, allowing the additives in the weighing hopper 9 to flow into the third feed pipe 22. The control panel 3 controls the operation of the first motor 25, which drives the ball 23 to rotate continuously. During the rotation of the ball 23, the additives drip from the feed hole 24 into the resin paint, achieving the addition of the additives. The reaction between the resin paint and the additives is accompanied by exothermic reactions, gas release, and unstable mixing. During this process, the drive motor 26 operates to drive the stirring... Rotating rod 27 stirs the resin paint and additives, achieving uniform mixing. Simultaneously, temperature and pressure sensors inside cylinder 2 detect the internal temperature and pressure. The temperature sensor is a dd1850, and the pressure sensor is an MPXV5004. The temperature and pressure sensors send the detected data to control panel 3 in real time. If the temperature and pressure are high, it indicates that the additive is dripping too fast. At this time, the control system inside control panel 3 will control the rotation speed of the first motor 25 shaft to slow it down, thus slowing down the additive dripping speed. This structure can control the dripping speed of the additive, keeping the mixture in a stable state and improving the usability of the device.
