[0032] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0033] The following will describe the present invention in detail with reference to the accompanying drawings. A two-component mixing system disclosed in this embodiment is as Figure 1 shown, including an A storage bin 2 and a B storage bin 4. The A storage bin 2 and the B storage bin 4 are connected to a mixing and reflux device 5. The mixing and reflux device 5 is connected to a mixing device 6. A cleaning device 7 and a drying device 8 are respectively arranged on both sides of the mixing device 6. The mixing device 6 is also connected to a nozzle 9.

[0034] As Figure 1 、 Figure 2 shown, an A feeding port 201 and an A return material port 202 are opened at the upper end of the A storage bin 2, and an A discharging port 203 is opened at the lower end. The A feeding port 201 is connected to the A storage tank 1 through a pipeline, and an A feeding pump 11 is arranged on the pipeline between the A feeding port 201 and the A storage tank 1; the A material in the A storage tank 1 is transported into the A storage bin 2 through the A feeding pump 11.

[0035] Similarly, as Figure 1 、 Figure 2 shown, a B feeding port 401 and a B return material port 402 are opened at the upper end of the B storage bin 4, and a B discharging port 403 is opened at the lower end. The B feeding port 401 is connected to the B storage tank 3 through a pipeline, and a B feeding pump 31 is arranged on the pipeline between the B feeding port 401 and the B storage tank 3; the B material in the B storage tank 3 is transported into the B storage bin 4 through the B feeding pump 31.

[0036] It is understandable that the tank bodies of both the A storage tank and the B storage tank adopt stainless steel jacketed tank bodies in the prior art, and are connected with heating devices to ensure the stable temperature inside the tanks and prevent the raw materials inside the tanks from deteriorating. The A material tank 1, the A storage tank 2, the B material tank 3, and the B storage tank 4 are all provided with breathing valves to balance the pressure changes inside each tank during feeding and discharging.

[0037] As Figure 1 , Figure 2 shown, a first channel 506 is provided inside the mixing reflux device 5. The cross-section of the first channel 506 is square and runs through the mixing reflux device 5 vertically from the center of the top end of the mixing reflux device 5; a second channel 507 and a third channel 508 are also provided inside the mixing reflux device 5. The second channel 507 is located in the upper half of the mixing reflux device 5, and the third channel 508 is located in the lower half of the mixing reflux device 5; both the second channel 507 and the third channel 508 are perpendicular to the first channel 506, and the second channel 507 and the third channel 508 also run through the mixing reflux device 5.

[0038] As Figure 1 , Figure 2 shown, a first return port 502 and a second return port 504 are provided on both sides of the second channel 507; a first feed port 501 and a second feed port 503 are provided on both sides of the third channel 508. The bottom of the first channel is connected to a mixing material pipe 505, and the mixing material pipe 505 is connected to a mixing device 6.

[0039] As Figure 1 , Figure 2 shown, the A discharge port 203 is connected to the first feed port 501 through a pipeline, and the A return port 202 is connected to the first return port 502 through a pipeline; an A feeding pump 21 is provided between the A discharge port 203 and the first feed port 501, an A feeding meter 22 is provided between the A feeding pump 21 and the A discharge port 203, and a first valve 23 is provided between the A feeding meter 22 and the A discharge port 203.

[0040] Similarly, the B discharge port 403 is connected to the second feed port 503 through a pipeline, and the B return port 402 is connected to the second return port 504 through a pipeline; a B feeding pump 41 is provided between the B discharge port 403 and the second feed port 503, a B feeding meter 42 is provided between the B feeding pump 41 and the second feed port 503; a second valve 43 is provided between the B feeding meter 42 and the B discharge port 403.

[0041] During the mixed feeding process, the first valve 23 and the second valve 43 are opened, and the A feeding pump 21 and the B feeding pump 41 respectively transport the A material and the B material into the mixing and reflux device 5. After the feeding is completed, the A feeding pump 21 and the B feeding pump 41 are closed, and then the first valve 23 and the second valve 43 are closed.

[0042] By setting the A feeding meter or the B feeding meter to monitor during the mixed feeding process, the staff can know the actual amounts of the A material and the B material that have been mixed respectively; if the actual feeding amount of one side is less than the expected amount, the staff can control the feeding pump on the side with less amount to slightly increase the power to increase the flow rate on this side to make up the amount; it can be understood that when the mixing ratios on both sides are different, the feeding flow rates on both sides are also different.

[0043] In this embodiment, a telescopic electric cylinder 51 is provided at the top of the mixing and reflux device 5. The output end of the telescopic electric cylinder 51 is connected to a piston baffle 52, and the piston baffle 52 is arranged inside the first channel 506; the piston baffle 52 includes two baffles 521 and two pistons 522, and the piston baffle 52 presents a "dry" shape.

[0044] As Figure 1 、 Figure 3 shown, the cross-sections of the baffle 521 and the piston 522 are also square. The difference is that one side of the baffle 521 perpendicular to the second channel is the same as the cross-sectional size of the first channel, and the other side is smaller than the first channel; the size of the piston 522 is the same as the cross-sectional size of the first channel. This can form channels between both sides of the baffle and the first channel.

[0045] In this embodiment, the length of the baffle 521 must be greater than the distance from the top of the second channel to the bottom of the third channel, so as to ensure that in the initial state of the telescopic electric cylinder 51, the piston 522 on the piston baffle 52 is above the second channel, and the piston 522 below is above the third channel; when the telescopic electric cylinder 51 drives the piston baffle 52 to move downward, the piston 522 above can be above the second channel, and the piston 522 below can be below the third channel. It should be noted that the piston 522 above shall not extend out of the upper end of the first channel.

[0046] In the initial state of the telescopic electric cylinder 51, as Figure 1As shown in the figure, this is the stage of feeding and mixing materials. Material A enters the third channel from the first feeding port, and material B enters the third channel from the second feeding port. Blocked by the piston 522 below, materials A and B can only enter the mixing material pipe 505 downward; under the action of the baffle 521 below, materials A and B enter the mixing material pipe 505 separately; this is because if the ratio of material A to material B is not 1:1, the flow rates on both sides will surely be different. If the baffle 521 below is not provided, the flow rate on one side is large while the flow rate on the other side is small, which may block the feeding port on the side with a small flow rate.

[0047] As Figure 2 shown in the figure, when the output end of the telescopic electric cylinder 51 extends to the maximum amount, the piston baffle 52 moves downward. The upper piston 522 is located above the second channel, and the lower piston 522 can be located below the third channel; this is the state of returning materials. As Figure 2 shown in the figure, a return channel for materials A and B is formed. Neither material A nor material B can enter the mixing material pipe 505 anymore and can only return to their respective storage tanks. When the mixing needs to be temporarily stopped, the staff only needs to control the telescopic electric cylinder 51 to move the piston baffle 52 downward, so as to block the mixing material pipe 505 and open the two return channels at the same time, then the mixing process can be temporarily terminated, and materials A and B can return to their respective storage tanks without closing their respective feeding pumps.

[0048] As Figure 1 、 Figure 2 、 Figure 4 shown in the figure, the mixing device 6 includes a mixing tank 61. A stirring motor 62 is arranged on the front side of the mixing tank 61. A stirring shaft 63 is rotatably connected in the mixing tank 61. Multiple stirring blades 64 are arranged on the stirring shaft 63, and the output end of the stirring motor 62 is connected to one end of the stirring shaft 63. The center opening at the top of the mixing tank 61 is connected to the mixing material pipe 505. After the mixed materials A and B enter the mixing tank 61, they are further mixed evenly under the stirring of the stirring blades 64. The bottom of the mixing tank 61 is connected to a spray head 9 for spraying out the mixed materials. It can be understood that the spray head here can use the existing technology to spray out the mixed materials.

[0049] A cleaning device 7 and a drying device 8 are respectively arranged on both sides of the mixing device 6. The cleaning device 7 includes a first horn nozzle 71 arranged in the mixing tank 61 and a high-pressure water pump 72 connected to the first horn nozzle 71 for cleaning the inside of the mixing tank 61; remove the pipeline connected to the spray head 9, place a waste bucket under the mixing tank 61, and collect the waste liquid after cleaning. The drying device 8 includes a second spray nozzle 81 and a high-pressure hair dryer 82 for drying the cleaned mixing tank 61.

[0050] Although the specific implementation manners of the present utility model have been described above in conjunction with the accompanying drawings, they do not limit the protection scope of the present utility model. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present utility model are still within the protection scope of the present utility model.
