[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0033] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0034] like Figures 1-11As shown, this utility model provides a high-viscosity stepless ratio electric spraying system, including: a system body 100, which includes a first metering electric booster pump group 3, a first storage tank group 4, a first feeding group 5, a first pipeline raw material heating group 6, and a pressure storage mechanism 7. The first metering electric booster pump group 3, the first storage tank group 4, the first feeding group 5, the first pipeline raw material heating group 6, and the pressure storage mechanism 7 are mounted on a main frame 101. Multiple casters 102 are installed at the bottom of the main frame 101, allowing the system body 100 to be moved to the spraying position. Furthermore, a control cabinet 1 can be installed on the main frame 101. Specifically, the first feeding group 5 and the first storage tank group 4 are located on the left side of the main frame 101, the first metering electric booster pump group 3 is located in the middle of the main frame 101, the pressure storage mechanism 7 can be located on the left side of the main frame 101, and the first pipeline raw material heating group 6 can be located below the pressure storage mechanism 7, thus better arranging them on the main frame 101. The control cabinet 1 can control the first metering electric booster pump group 3, the first storage tank group 4, the first feeding group 5, the first pipeline raw material heating group 6, and the pressure storage mechanism 7 for convenient use.

[0035] Furthermore, the aforementioned first metering electric booster pump group 3, first feeding group 5, and pressure storage mechanism 7 are respectively connected to the first storage tank group 4. The first metering electric booster pump group 3 is connected to the first pipeline raw material heating group 6, and the first pipeline raw material heating group 6 is connected to the spray gun 200. In use, raw materials are added to the first feeding group 5, and then the first feeding group 5 supplies the raw materials into the first storage tank group 4. The pressure storage mechanism 7 is used to supply high-pressure air into the first storage tank group 4, so that the raw materials can be transported to the first pipeline raw material heating group 6 for heating through the first metering electric booster pump group 3. Here, the first metering electric booster pump group 3 can adjust the speed over a wide range to achieve stepless ratio, which has high mechanical efficiency and can provide accurate feedback, thus accurately metering and achieving high-pressure delivery with ultra-high thrust, and then delivering it to the spray gun 200 for spraying operation. The high-viscosity stepless ratio electric spraying system of this utility model integrates the first metering electric booster pump group 3, the first storage tank group 4, the first feeding group 5, the first pipeline raw material heating group 6, and the pressure storage mechanism 7. Compared with the traditional spraying system, it does not rely on a hydraulic station or air station, has more relaxed requirements for equipment use, and is convenient for construction and use.

[0036] It should be noted that the aforementioned pressure storage mechanism 7 includes a pressure storage tank 71 and an air compressor 72. The pressure storage tank 71 and the air compressor 72 are configured and installed on the main frame 101. The main frame 101 has an air compressor frame 104. The pressure storage tank 71 and the air compressor 72 are installed on the air compressor frame 104, while the aforementioned first pipeline raw material heating group 6 is installed below the air compressor frame 104.

[0037] Since the raw material in the first storage tank group 4 is of high viscosity, and viscosity is inversely proportional to flowability (i.e., low-viscosity fluids have low resistance to flow, while high-viscosity fluids have high resistance and require greater external force to drive them), after the pressure storage tank 71 is connected to the first storage tank group 4, the air compressor 72 can be started through the control cabinet 1 to add high-pressure air into the pressure storage tank 71. The pressure storage tank 71 then delivers the high-pressure air to the first storage tank group 4, creating a positive pressure within the first storage tank group 4 to push the raw material to the outlet quickly. This ensures that the first metering electric booster pump group 3 has sufficient raw material for metering during operation, preventing the first metering electric booster pump group 3 from failing to work properly due to high viscosity and poor flowability of the raw material.

[0038] Exemplary first metering electric booster pump set

[0039] like Figure 2 As shown, further, some embodiments of this utility model provide the specific structure of the first metering electric booster pump group 3 described above. Here, the first metering electric booster pump group 3 includes a pump frame 301, a first pump body 302, a first telescopic cylinder 303, and a first motor 304. The first telescopic cylinder 303 is configured and installed on the upper part of the pump frame 301, the first pump body 302 is configured and installed on the lower part of the pump frame 301 and connected to the first telescopic cylinder 303, and the first motor 304 is configured and installed on the upper part of the first telescopic cylinder 303 and located on one side thereof. The first motor 304 is rotatably connected to the first telescopic cylinder 303 through a synchronous pulley and a transmission belt (not shown), so that the first metering electric booster pump group 3 can adjust the speed over a wide range to achieve stepless ratio, and has high mechanical efficiency and can provide accurate feedback, thereby accurately metering and realizing high-pressure delivery with ultra-high thrust. Therefore, when the first motor 304 starts, it drives the first telescopic cylinder 303 to rotate, and the first telescopic cylinder 303 can drive the first pump body 302 to suck up the raw material, so that the raw material is transported from the first storage tank group 4 through the first pump body 302 to the first pipeline raw material heating group 6 for heating, and then transported to the spray gun 200 for spraying operation.

[0040] Exemplary first storage tank group

[0041] like Figures 3-4As shown, further, some embodiments of this utility model provide a specific structure of the first storage tank group 4 described above. This first storage tank group 4 includes an outer tank body 401, with a top cover 402 installed at the upper end of the outer tank body 401. An inner tank body 403 is also installed inside the outer tank body 401, with the upper end of the inner tank body 403 connected to the top cover 402. A stirring motor 404 is installed on the top cover 402, and a stirring frame 405 is installed inside the inner tank body 403 for stirring. The frame 405 is connected to the stirring motor 404, and the bottom of the inner tank 403 is connected to the discharge pipe 406 at the bottom of the outer tank 401. The raw materials conveyed by the first feeding group 5 enter the inner tank 403 through the feed port on the top cover 402, while the stirring motor 404 (the stirring motor 404 is a stepless speed regulating motor) can be steplessly speed regulated, thereby driving the stirring frame 405 to stir the raw materials, improve their fluidity, and convey them to the first metering electric booster pump group 3 through the discharge pipe 406 at the bottom.

[0042] Furthermore, there is a space between the outer tank 401 and the inner tank 403, and a heat-conducting medium (water) is contained in the space. A heater 407 and a temperature sensor 408 are installed on the outer tank 401. The heat-conducting medium (water) is heated by the heater 407, and the heat is transferred to the inner tank 403, thereby heating the raw materials inside, improving their fluidity, and facilitating the delivery of the raw materials to the first metering electric booster pump group 3. Furthermore, a liquid level sensor 409 is also installed on the top cover 402, and a heat-conducting medium liquid level gauge 410 is installed on the outer tank 401. The liquid level sensor 409 and the heat-conducting medium liquid level gauge 410 are used to detect the position of the raw materials and the heat-conducting medium (water) respectively, which is convenient for use.

[0043] Example First Feeding Group

[0044] like Figures 5-7As shown, further, some embodiments of this utility model provide a specific structure of the first feeding group 5 described above. This first feeding group 5 includes a feeding cylinder frame 501, a second pump body 502, a second telescopic cylinder 503, a second motor 504, and a pressure plate 505. Here, the second telescopic cylinder 503 is mounted on the feeding cylinder frame 501, the second motor 504 is mounted on the upper end of the second telescopic cylinder 503, the second pump body 502 is mounted on the lower end of the second telescopic cylinder 503, and the pressure plate 505 is mounted on the second... At the lower end of the pump body 502, the raw material barrel 506 is installed below the pressure plate 505. Raw materials are added into the raw material barrel 506. By activating the feeding cylinder frame 501, the feeding cylinder frame 501 can move downward, and the pressure plate 505 slides in the raw material barrel 506 to squeeze the raw materials. At the same time, after the second motor 504 is started, the second motor 504 drives the second telescopic cylinder 503 to work, and the second telescopic cylinder 503 drives the second pump body 502 to suck up the raw materials and transport the raw materials to the first storage tank group 4 for stirring.

[0045] The second telescopic cylinder 503 includes an outer cylinder body 5031, an inner screw 5032, and a telescopic cylinder 5033. The inner screw 5032 is rotatably installed inside the outer cylinder body 5031, while the telescopic cylinder 5033 is installed inside the outer cylinder body 5031 in a linear up-and-down motion. The lower end of the inner screw 5032 extends into the telescopic cylinder 5033, and the inner screw 5032 and the telescopic cylinder 5033 are connected by a thread. Therefore, when the inner screw 5032 rotates, it can drive the telescopic cylinder 5033 to move up and down. The telescopic cylinder 5033 is connected to the piston rod 5021 of the second pump body 502. The telescopic cylinder 5033 drives the piston rod 5021 to move up and down reciprocally within the second pump body 502, thereby achieving the suction of raw materials.

[0046] Furthermore, the pressure plate 505 has a feed pressure hole 5051 corresponding to the second pump body 502. So when the pressure plate 505 moves downward, the raw material can be pressed into the second pump body 502 through the feed pressure hole 5051. The pressure plate 505 has a circumferential groove on its outer periphery, and a sealing ring 5052 is installed in the circumferential groove to prevent the raw material from being squeezed out between the pressure plate 505 and the raw material barrel 506.

[0047] Exemplary first pipeline raw material heating group

[0048] like Figures 8-9As shown, further, some embodiments of this utility model provide a specific structure of the first pipeline raw material heating group 6 described above. Here, the first pipeline raw material heating group 6 of this structure includes a heating box 601, a heating rod 602, and a heat exchange coil 603. The heating rod 602 and the heat exchange coil 603 are configured and installed inside the heating box 601, and the heating rod 602 passes through the heat exchange coil 603. An inlet pipe 6031 and an outlet pipe 6032 are configured and installed on the heating box 601. The inlet pipe 6031 and the outlet pipe 6032 are respectively connected to the two ends of the heat exchange coil 603. Here, the first pump body 30 of the first metering electric booster pump group 3 delivers the raw material into the inlet pipe 6031 to enter the heat exchange coil 603. The heating box 601 contains a heating medium (water), which can be heated by the heating rod 602 and the heat can be transferred to the heat exchange coil 603 to heat the raw material in the heat exchange coil 603, thereby improving the fluidity of the raw material. Then, it is output from the outlet pipe 6032, which facilitates the spraying operation of the spray gun 200 and improves the spraying effect.

[0049] Furthermore, a liquid level pipe (not shown) is installed on one side of the heating box 601, which allows for easy observation of the position of the heating medium (water) inside, facilitating its addition. A heat exchange medium filling port 605 and an exhaust valve 606 are installed at the upper end of the heating box 601. The heating medium can be added through the heat exchange medium filling port 605, while the exhaust valve 606 can discharge excess high-temperature gas, increasing safety.

[0050] Exemplary cleaning mechanism

[0051] like Figures 10-11 As shown, the system main body 100 further includes a cleaning mechanism 2, which is installed on one side of the control cabinet 1. Specifically, the cleaning mechanism 2 includes a cleaning fluid tank 201, a third pump body 202, a third telescopic cylinder 203, and a third motor 204. The third telescopic cylinder 203 is mounted on the cleaning fluid tank 201 via a cylinder frame 2031. The third pump body 202 is installed inside the cleaning fluid tank 201 and is connected to the lower end of the third telescopic cylinder 203. The third motor 204 is mounted on the third telescopic cylinder 204. The upper end of the telescopic cylinder 203 is located on one side. After the third motor 204 is started, the third motor 204 is rotatably connected to the third telescopic cylinder 203 through a synchronous pulley and a transmission belt (not shown). Then, the third telescopic cylinder 203 drives the piston rod of the third pump body 202 to perform suction work, drawing the cleaning liquid in the cleaning liquid tank 201 outward. In this way, the third pump body 202 delivers the cleaning liquid to the portable handheld mixing block 205, thereby cleaning the delivery pipeline 8 between the portable mixing block 205 and the spray gun 200, facilitating the use of the spray gun 200.

[0052] It should be noted that the first telescopic cylinder 303, the second telescopic cylinder 503, and the third telescopic cylinder 203 mentioned above have the same structure, and the first pump body 302, the second pump body 502, and the third pump body 202 mentioned above have the same structure; all of them are piston pumps.

[0053] like Figure 12 As shown, the main body 100 of the system further includes: a second metering electric booster pump group 3a, a second storage tank group 4a, a second feeding group 5a, and a second pipeline raw material heating group 6a. The second metering electric booster pump group 3a, the second feeding group 5a, and the pressure storage mechanism 7 are respectively connected to the second storage tank group 4a. The second metering electric booster pump group 3a is connected to the second pipeline raw material heating group 6a, and the second pipeline raw material heating group 6a is connected to the spray gun 200.

[0054] It should be noted that the second metering electric booster pump group 3a, the second storage tank group 4a, the second feeding group 5a, and the second pipeline raw material heating group 6a have the same structure as the first metering electric booster pump group 3, the first storage tank group 4, the first feeding group 5, and the first pipeline raw material heating group 6, and are symmetrically installed on the main frame 101. This allows the main body 100 of the system to mix and spray two kinds of raw materials, thereby increasing the application range of the main body 100 of the system.

[0055] like Figure 13 As shown, two metering valves 206 are installed in the cleaning fluid tank 201. The first pipeline raw material heating group 6 and the second pipeline raw material heating group 6a are connected to the two metering valves 206 through pipelines respectively. The two metering valves 206 control the ratio of the two raw materials and deliver them to the spray gun 200 for mixing and spraying.
