[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0044] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0045] like Figures 1-11 As shown, the present invention provides a high-viscosity stepless ratio electric spraying system, including: a system main body 100, the system main body 100 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 gas storage mechanism 7, wherein the above-mentioned 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 gas storage mechanism 7 are installed on a main frame 101, and a plurality of moving wheels 102 are installed at the bottom of the main frame 101, so that the system main body 100 can be moved to the spraying construction position; further Furthermore, a control cabinet 1 can also 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 gas 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 gas storage mechanism 7, so as to better arrange it on the main frame 101; and the above-mentioned 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 gas storage mechanism 7 for convenient use;

[0046] Furthermore, the above-mentioned first metering electric booster pump group 3, first feeding group 5, and pressure air 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. When 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 air storage mechanism 7 is used to supply high-pressure air into the first storage tank group 4, and then the raw materials are conveniently 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 number of revolutions in a wide range to achieve a stepless ratio, has high mechanical efficiency and can provide precise feedback, and thus accurately measure, and can achieve ultra-high thrust high-pressure transportation, and then transport it to the spray gun 200 to enter the spraying operation. The high-viscosity stepless ratio electric spray system of the present invention integrates the above-mentioned 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 gas storage mechanism 7. Compared with traditional spray systems, it does not need to rely on hydraulic stations or gas stations, has relatively loose requirements for the use of equipment, and is convenient for construction and use.

[0047] It should be noted that the pressure gas storage mechanism 7 includes a pressure gas storage tank 71 and an air compressor 72. The pressure gas storage tank 71 and the air compressor 72 are arranged and mounted on the main frame 101. The main frame 101 has an air compressor frame 104. The pressure gas storage tank 71 and the air compressor 72 are mounted on the air compressor frame 104. The first pipeline raw material heating group 6 is mounted below the air compressor frame 104.

[0048] Since the raw materials in the first storage tank group 4 are of high viscosity, and viscosity is inversely proportional to fluidity, that is, low-viscosity fluids have little resistance when flowing, while high-viscosity fluids have great resistance when flowing and require greater external force to drive. Therefore, 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, and then high-pressure air can be added to the pressure storage tank 71. The pressure storage tank 71 then delivers the high-pressure air to the first storage tank group 4. Positive pressure will exist in the first storage tank group 4 to push the raw materials to flow quickly to the outlet, ensuring that the first metering electric booster pump group 3 has sufficient raw materials for metering during operation, and preventing the first metering electric booster pump group 3 from being disconnected and unable to work normally due to the high viscosity and poor fluidity of the raw materials.

[0049] Exemplary first metering electric booster pump group: Figure 2As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned first metering electric booster pump group 3, where the first metering electric booster pump group 3 of the structure includes a pump frame 301, a first pump body 302, a first telescopic cylinder 303, and a first motor 304, wherein the first telescopic cylinder 303 is configured to be installed on the upper part of the pump frame 301, the first pump body 302 is configured to be installed on the lower part of the pump frame 301, and is connected to the first telescopic cylinder 303, the first motor 304 is configured to be installed on the upper part of the first telescopic cylinder 303 and is located on one side thereof, and the first motor 304 is rotatably connected to the first telescopic cylinder 303 through a synchronous wheel and a transmission belt (not shown), so that the first metering electric booster pump group 3 can adjust the number of revolutions in a wide range to achieve a stepless ratio, and has high mechanical efficiency and can provide precise feedback, thereby accurately metering, and can achieve ultra-high thrust and high-pressure delivery. Therefore, when the first motor 304 starts and drives the first telescopic cylinder 303 to rotate, the first telescopic cylinder 303 can drive the first pump body 302 to suck 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.

[0051] Furthermore, there is a accommodating space between the outer tank body 401 and the inner tank body 403, and there is a heat-conducting medium (water) in the accommodating space. A heater 407 and a temperature sensor 408 are installed on the outer tank body 401. The heat-conducting medium (water) is heated by the heater 407, and the heat is transferred to the inner tank body 403, thereby heating the raw materials inside to improve their fluidity and facilitate the transportation of the raw materials to the first metering electric booster pump group 3; further, 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 body 401.

Here, raw materials are added to the raw material barrel 506, and the loading cylinder frame 501 is started, and the loading cylinder frame 501 can move downward, and then 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 then the second telescopic cylinder 503 drives the second pump body 502 to suck the raw materials, and the raw materials are transported to the first storage tank group 4 for stirring.

[0054] 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, and a circumferential groove is provided on the outer periphery of the pressure plate 505, and a sealing ring 5052 is installed in the circumferential groove to prevent the raw material from being squeezed out from between the pressure plate 505 and the raw material barrel 506.

[0055] Exemplary first pipeline raw material heating group: Figure 8-Figure 9 As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned first pipeline raw material heating group 6, where the first pipeline raw material heating group 6 of the structure includes a heating box 601, a heating rod 602, and a heat exchange coil 603, wherein the heating rod 602 and the heat exchange coil 603 are configured and installed in the heating box 601, and the heating rod 602 is passed through the heat exchange coil 603, and an inlet pipe 6031 and an outlet pipe 6032 are configured and installed on the heating box 601, and 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 transports the raw material into the inlet pipe 6031 to enter the heat exchange coil 603, and the heating box 601 contains a heating medium (water).

Specifically, the cleaning mechanism 2 of the structure includes a cleaning liquid tank 201, a third pump body 202, a third telescopic cylinder 203, and a third motor 204, wherein the third telescopic cylinder 203 is installed on the cleaning liquid tank 201 through a cylinder frame 2031, the third pump body 202 is installed in the cleaning liquid tank 201, the third pump body 202 is connected to the lower end of the third telescopic cylinder 203, and the third motor 204 is provided. The device is installed at the upper end of the third telescopic cylinder 203 and is located on one side thereof. After starting the third motor 204, the third motor 204 is rotatably connected to the third telescopic cylinder 203 through a synchronous wheel and a transmission belt (not shown), and then the third telescopic cylinder 203 drives the piston rod of the third pump body 202 to perform suction work, and draws out the cleaning liquid in the cleaning liquid tank 201. In this way, the third pump body 202 transports the cleaning liquid to the portable handheld mixing block 205, and then cleans the delivery pipeline between the portable handheld mixing block 205 and the spray gun 200, thereby facilitating the use of the spray gun 200.

[0059] Example spray delivery pipe set: Figure 11-12 As shown, although the above embodiments of the present invention include a cleaning mechanism 2, the cleaning effect of the cleaning mechanism 2 is limited. After long-term use or if the operator fails to clean it in time, residual material will inevitably remain in the delivery pipeline, which will cause internal blockage of the delivery pipeline over time. To solve the above problem, in some embodiments of the present invention, the spray gun 200 is connected to a spray delivery pipe assembly 8. The spray delivery pipe assembly 8 includes multiple delivery pipe sections 81, and adjacent delivery pipe sections 81 are connected by a fastening module 82. By designing the spray delivery pipe assembly 8 as multiple delivery pipe sections 81 instead of a single entire delivery pipe, several of the delivery pipe sections 81 can be replaced, thereby reducing the cost of replacing the entire delivery pipe section. Furthermore, the control line (not shown) of the spray gun 200 is installed in the fastening module 82. In this way, the control line can be better fixed to the spray delivery pipe assembly to prevent entanglement during use and facilitate the subsequent rewinding of the two, thereby improving the rewinding effect.

It should be noted that one end of the conveying pipe section 81 has an end cap 811, and the other end has a thread corresponding to the end cap 811, so that two adjacent conveying pipe sections 81 can be connected through the end cap 811. Therefore, the first C-shaped lock 83 and the second C-shaped lock 84 can be fastened and fixed on the end cap 811, and the C-shaped inner lock seat 85 is configured and installed in the inner lock groove 841 of the second C-shaped lock 84, and the control line is passed between the C-shaped inner lock seat 85 and the end cap 811.

[0063] Furthermore, in some embodiments of the present invention, a C-shaped inner buckle lock piece 852 is configured and installed in the inner C-shaped groove 851 of the C-shaped inner buckle lock seat 85, and an inner driving member is configured and installed in the outer C-shaped groove 857 of the C-shaped inner buckle lock piece 852.
