[0028] The specific implementation process is as follows:

[0029] When the conveying system needs to be used, it can be controlled through the host control screen 2. First, install it on the textile dyeing machine that needs to be fed. The trough of this machine is the trough 7. Connect the six groups of feeding pumps 3 to the external material barrels or additive barrels through the extraction pipes, and then the mixing and circulating work can start;

[0030] Start the feeding pump 3 to start working. The feeding pump 3 extracts the additives. After extraction, it enters the mixing bin 53 through the pipeline to the feeding tray 54 for mixing. The proportion of the additives can be controlled by controlling the extraction degree of each feeding pump 3. The mixed additives are discharged through the discharge pipe 45 at the bottom of the mixing tank, and then enter the first three-way conversion valve 46. Control the first three-way conversion valve 46 to achieve feeding into the material tank 7 or the auxiliary barrel 8. When the additives enter the first feeding pipe 47, the first feeding pipe 47 conveys the additives to the auxiliary barrel feeding pipe 62, and at the same time, the second water inlet valve 618 is opened, so that the external water enters through the second water injection pipe 617 and is mixed with the additives in the auxiliary barrel feeding pipe 62, and then is conveyed into the auxiliary barrel 8. If recycling is required, it is discharged from the auxiliary barrel discharge pipe 69 at the bottom of the auxiliary barrel 8, and the left end of the second three-way conversion valve 66 is started to open, and then detected by the material detection device 65, enters the return pipe 64, and is extracted by the circulating pump feeding pipe 44 on the right side of the circulating pump 42, and enters the mixing tank 5 through the mixing tank feeding pipe 43 at the top for continuous mixing, and thus circulates; the auxiliary barrel 8 can also feed the material tank 7. Start the feeding valve 611, and the material in the auxiliary barrel guide pipe 610 can be introduced into the material tank 7.

[0031] When direct circulating feeding is required inside the material tank 7, start the bottom of the first three-way conversion valve 46 to open. The additives are discharged from the second feeding pipe 48 and enter the material tank feeding pipe 61. Then open the first water inlet valve 614, and the first water injection pipe 613 injects water into the material tank feeding pipe 61 for mixing, and then sends it into the material tank 7. The bottom of the material tank 7 is connected with a material tank discharge pipe 67. After the material tank discharge pipe 67 discharges the material, it passes through the second three-way conversion valve 66 into the return pipe 64, and then is sent back to the mixing bin 53 by the circulating pump 42 for mixing. The material tank discharge pipe 67 is equipped with a material tank water weight sensor 68, and the material tank water weight sensor 68 can detect the water weight inside the material tank 7 to perform automatic and efficient circulating feeding.

[0032] Through the first water injection pipe 613 and the second water injection pipe 617, combined with circulating mixing, the pipeline assembly 6, the mixing and circulating tank 4 and the mixing tank 5 can be efficiently cleaned.

[0033] The set hopper water weight sensor 68 can be used by the main machine 1 to proportion materials according to the percentage of water weight. In cooperation with the feeding pump 3, the weight of the discharged materials per second can be calculated for each type of material. The name of each type of material and the weight per second are set on-site. After the batching is completed and the feeding stops, water is added through two groups of water injection pipes. When the water level drops to 10%, the water taken away by each meter of cloth is automatically calculated, and then the weight of the materials used per meter of cloth is calculated. Then, the feeding is quickly carried out, and water is added to the set water level. According to the speed of the calender, the materials used per meter of cloth are known. Each type of supplementary material will be added to the mixing bin 53. When the fabric batch is almost completed, the auxiliary barrel 8 is manually switched to circulate and prepare the materials for the next batch. When changing to the next batch of materials, the auxiliary barrel 8 is opened to discharge the materials, and the materials are quickly discharged into the machine hopper 7. Before batching, the machine hopper or the spare hopper can be cleaned with a circulating pump.

Although the present invention 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 perform equivalent replacements for some of the technical features.
