When discharging materials, the quantitative distribution device 12 rotates so that the quantitative material collection space 122 is aligned with the pipeline, and the putty powder enters the first stirring container 3 through the pipeline. The required number of transportation cycles can be obtained by dividing the required amount of putty powder by the loading amount of the quantitative material collection space 122. The first raw material container 1 distributes putty powder based on the number of transportation cycles.

[0031] The second raw material container 2 is used to distribute water, and the amount of water is controlled by the conduction time of the first solenoid valve 21 and the second solenoid valve 22 .

The structure of the second stirring module 46 is the same as that of the first stirring module 37, which will not be described in detail.

[0035] Based on the above putty paste precise batching system, the putty paste precise batching method specifically includes the following steps:

[0036] S1. The first raw material container 1 inputs a fixed amount of putty powder into the first stirring container 3 , and the second raw material container 2 inputs a fixed amount of water into the first stirring container 3 .

[0037] S2, the first stirring container 3 stirs the putty powder and water evenly. The stirring process of the first stirring container 3 is to start the first heating module 33, the first stirring module 37 starts four stirring action devices at the same time to stir, after stirring for the first predetermined time, the surface image of the putty paste is captured by the camera 36, ​​and each first density detection module is started to detect the density of the putty paste at different positions, the first controller 31 determines the area with lumps according to the image captured by the camera 36, ​​and determines the area with uneven density according to the data of the first density detection module, and starts the stirring action devices corresponding to the area with lumps and the area with uneven density to work, and after working for the second predetermined time, repeat the above judgment process until the area with lumps and the area with uneven density disappear completely.

[0038] S3, the first stirring container 3 transfers the evenly stirred putty paste to the second stirring container 4, and the viscosity detection module 5 detects the viscosity of the putty paste output from the first stirring container 3. The detection process of the viscosity detection module 5 is that since the putty paste will block the reception of infrared rays during the falling process, whenever the infrared receiving module 512 in the viscosity detection unit 51 cannot receive a signal, it will send a signal to the calculation unit. The calculation unit extracts the time when each layer of viscosity detection unit sends a signal for the first time, and takes the distance between the two layers of viscosity detection units divided by the time difference when the two layers of viscosity detection units first send a signal as the final result.

[0039] S4, the second stirring container 4 performs a stirring operation according to the detection result of the viscosity detection module 5. The stirring process of the second stirring container 4 is to receive the calculation result of the viscosity detection module 5. If the absolute value of the error between the calculation result and the first threshold is less than the error threshold, it means that the viscosity of the putty paste meets the requirements, and the second stirring container 4 does not need to work;

[0040] If the calculated result is less than the first threshold value, and the absolute value of the error between the calculated result and the first threshold value is greater than the error threshold value, it means that the putty paste is too viscous. The amount of water to be added is determined according to the absolute value of the error between the calculated result and the first threshold value, and the second solenoid valve 22 is opened to inject water into the second stirring container 4. The second stirring module 46 simultaneously starts four stirring action devices for stirring. After stirring for the first predetermined time, each second density detection module is started to detect the density of the putty paste at different positions. The area with uneven density is determined according to the data of the second density detection module, and the stirring action device corresponding to the area with uneven density is started to work. After working for the second predetermined time, the above judgment process is repeated until all the areas with uneven density disappear.

[0041] If the calculation result is greater than the first threshold, and the absolute value of the error between the calculation result and the first threshold is greater than the error threshold, it means that the putty is too thin, and the second heating module 43 is turned on, and the second stirring module 46 simultaneously starts four stirring action devices for stirring, and stops working after stirring for the second predetermined time to evaporate excess water and increase viscosity.

[0042] The above disclosure is only the preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the present invention. It should be pointed out that for those skilled in the art, any equivalent changes made to the scheme of the present invention without departing from the design structure and principle of the present invention are considered to be within the protection scope of the present invention.
