Changes or adjustments in their relative relationships shall also be regarded as the scope of implementation of the utility model without substantial changes in technical content.

[0021] As Figures 1 - 2As shown in the figure, the powder quantitative automatic filling device of the present utility model mainly includes a dyeing machine 12 and a powder bin 1, and also includes a pushing mechanism, a chemical tank 7, an injection mechanism, a water pump 8 and a host computer. Among them, a weighing sensor 2 is arranged on the powder bin 1. The pushing mechanism pushes the powder in the powder bin 1 into the chemical tank 7. The liquid inlet of the water pump 8 is connected to the liquid outlet of the dyeing machine 12. The liquid outlet of the water pump 8 is respectively connected to the inlet of the chemical tank 7 and the injection mechanism. The inlet of the injection mechanism is also connected to the discharge port of the chemical tank 7. The outlet of the injection mechanism is connected to the liquid inlet of the dyeing machine 12. The weighing sensor 2 is electrically connected to the host computer. The weighing sensor 2 constantly detects the weight change of the powder bin 1 and transmits the detected weight signal to the host computer.

[0022] In order to ensure smooth material falling during the powder filling process, a stirrer 3 is arranged at the bottom of the powder bin 1. The stirrer 3 is electrically connected to the host computer and is intermittently started by the host computer.

[0023] In this embodiment, the pushing mechanism includes a feeding reduction motor 4 and a spiral pushing rod 5. The driving end of the feeding reduction motor 4 is connected to the spiral pushing rod 5. An outlet chute 14 is arranged at the bottom of the powder bin 1. The powder falls into the outlet chute 14. The spiral pushing rod 5 is arranged in the outlet chute 14 and pushes the powder in the outlet chute 14 into the chemical tank 7. Further, a blanking gate 13 is arranged between the pushing mechanism and the chemical tank 7. The spiral pushing rod 5 pushes the powder in the outlet chute 14 towards the blanking gate 13. The blanking gate 13 is connected to the ejector rod of the blanking gate cylinder 6. The opening and closing of the blanking gate 13 are controlled by the blanking gate cylinder 6. In order to improve the degree of production automation, the feeding reduction motor 4 is electrically connected to the host computer. The host computer adjusts the rotation speed of the feeding reduction motor in a timely manner according to the required time and the filling amount to be filled, so that linear filling and quantitative filling are easily achieved. The blanking gate cylinder 6 is also electrically connected to the host computer, so that it is convenient to control the time for injecting the powder into the chemical tank 7.

[0024] In this embodiment, the injection mechanism includes an injection valve 10 and an injector 11. The injection valve 10 is arranged between the liquid outlet of the water pump 8 and the inlet of the injector 11. The inlet of the injector 11 is also connected to the discharge port of the chemical tank 7. A chemical valve 9 is arranged between the liquid inlet of the chemical tank 7 and the liquid outlet of the water pump 8. The water pump 8 pumps the liquid inside the dyeing machine 12 and hydrolyzes and dissolves the powder falling into the chemical tank 7 through the chemical valve 9. The dissolved solution is injected into the injector 11. When the injection valve 10 is opened, the high-pressure liquid of the water pump 8 is injected into the injector 11. The injector 11 sucks the dissolved liquid in the chemical tank 7 and the liquid of the water pump 8 and injects and sprays them into the dyeing machine 12. The injection valve 10 introduces the liquid of the water pump 8 into the injector 11, increases the fluidity of the fluid for the injector 11, and improves the spraying efficiency.

[0025] In order to improve the degree of production automation, the material injection valve 10, the material melting valve 9, and the water pump 8 are respectively electrically connected to the upper computer, facilitating the upper computer to flexibly control the working time of the material injection valve 10, the material melting valve 9, and the water pump 8 according to production needs. Preferably, the upper computer is a PLC controller.

[0026] Working principle of the present utility model:

[0027] The powder bin 1 stores the powder required for printing and dyeing processing. The powder falls into the discharge chute 14. First, the upper computer controls the blanking gate cylinder 6 to open the blanking gate 13. The screw pusher 5 driven by the feeding reduction motor 4 pushes the powder in the discharge chute 14 to the blanking gate 13 and falls into the melting tank 7. During the process of adding powder, to ensure smooth addition, the upper computer intermittently controls the opening of the stirrer 3 at the bottom of the powder bin 1. When adding powder, the water pump 8 is turned on. The water pump 8 pumps the liquid inside the dyeing machine 12 and hydrolyzes and dissolves the powder falling into the melting tank 7 through the material melting valve 9. At the same time, the material injection valve 10 is opened. The high-pressure liquid of the water pump 8 enters the injector 11, and the injector 11 sucks the dissolved liquid in the melting tank 7 and the liquid of the water pump 8 and injects them into the dyeing machine 12 together. During the addition, the weighing sensor 2 constantly detects the weight change of the powder bin 1 and transmits the detected weight signal to the upper computer. The upper computer calculates the added amount by subtracting from the original weight value. When the added amount is equal to the required amount, the blanking gate cylinder 6 is immediately stopped, the blanking gate 13 is closed to stop the addition, and the water pump 8, the feeding reduction motor 4, the material melting valve 9, and the material injection valve 10 are closed. In this way, the automatic quantitative addition of powder according to production needs can be completed.

[0028] The automatic quantitative powder addition device of the present utility model replaces manual and extensive feeding. Through the weighing sensor 2 and the upper computer, the weight of the added powder can be accurately and real-time known, and the added material can be precisely controlled, meeting the demand for linear quantitative powder addition in the production process, promoting the refined management of the production process, and improving production efficiency. The upper computer can adjust the rotation speed of the feeding reduction motor 4 in a timely manner according to the required time and the added amount to be added, making it easier to achieve linear addition and quantitative addition. The material injection valve 10, the material melting valve 9, and the water pump 8 are respectively electrically connected to the upper computer, greatly improving the degree of production automation and saving labor costs and time costs.

[0029] The implementation manners of the present utility model are not limited to this. According to the above content of the present utility model, using the ordinary technical knowledge and customary means in this field, without departing from the above basic technical idea of the present utility model, the present utility model can also be modified, replaced, or combined in many other forms, all of which fall within the scope of the protection of the rights of the present utility model.
