[0037] At least two sampling small tanks 4 are located below the output end of the sampling discharge pipe 3 to receive the new energy battery positive material conveyed by the sampling discharge pipe 3, and the sampling small tank 4 is made of stainless steel and a self-sealing bag, which can quickly take out the sample and seal the package, and the sampling small tank 4 is designed with the maximum sampling capacity; and

[0038] A sample transportation assembly line 7 is used to sequentially transport each sampling small tank 4 to stop below the sampling discharge pipe 3 to receive the new energy battery positive material from the sampling discharge pipe 3; and

[0039] An infrared sensor 5 is installed on the side of the output end of the sample transportation assembly line 7 to sense the sampling small tank 4 with the material entering the sensing area; and

[0040] An alarm light 6, when the sample canister 4 with powder enters the sensing area, the alarm light 6 turns on the red alarm light, and the sample transportation line 7 cannot run, when the sample canister 4 with powder is taken away, the alarm light 6 turns on the green light and stops the alarm, and so on.

[0041] A controller 8, the controller 8 is used to control the servo motor 2, the sample transportation line 7, the alarm light 6, so as to achieve the accurate and accurate sampling to the sample canister 4. Specifically,

[0042] The sample transportation line 7 is connected to the controller 8, and the sample transportation line 7 is controlled to run by the controller 8, so as to achieve the automatic feeding of the empty sample canister 4 and the output of the sample canister 4 with powder, and the accurate stopping of the empty sample canister 4 at the position directly below the sampling and powder discharging pipe 3.

[0043] The infrared sensor 5 is connected to the controller 8, and the alarm light 6 is connected to the controller 8. When the sample canister 4 with powder flows to the sensing area, the infrared sensor 5 feeds back a signal to the controller 8, and the controller 8 receives the level signal of the infrared sensor 5 to control the alarm light 6 to turn on the red alarm light, reminding the worker to take the powder.

[0046] Working principle:

[0047] Debugging stage:

[0048] The running speed and the running time of the sample transportation line 7 are set, and then the position symbols of the sample canister 4 are marked on the sample transportation line 7 according to the position directly below the pipe opening of the sampling and powder discharging pipe 3. Then, the corresponding number of sample canisters 4 corresponding to the sampling times of the batch are placed (for example, 4 sample canisters 4 are placed corresponding to 4 times of sampling in the batch process).

[0049] Then the controller 8 sets the weight value of each sample tank 4 in turn (the weight value is controlled by the number of rotations of the servo motor 2 to control the discharge amount), and the relationship between the weight value and the number of rotations of the servo motor 2 is a prior art, which can be realized by any prior art. The automatic sampling can be set by interval time points, or the automatic sampling can be controlled by manually pressing the physical sampling control button 10 according to the bag number.

[0050] After debugging, the empty area in the small spiral conveying pipe 1 is manually filled with powder, otherwise there will be empty pipe area, which will cause the first tank weight to be inaccurate. After sampling is completed, the servo motor 2 is manually controlled to rotate and push out all the residual material powder in the small spiral conveying pipe 1 to prevent mixing with the next batch.

[0051] Running phase:

[0052] 1. Timed automatic sampling:

[0053] When the process requires sampling at fixed time points, the automatic powder sampling device of the utility model is opened synchronously when the new energy battery positive electrode material packaging machine is started. The automatic powder sampling device automatically counts down through the controller 8, and when the first set sampling time point is reached, the controller 8 controls the servo motor 2 to rotate the corresponding weight number of turns. The sample powder enters the small spiral conveying pipe 1 through the sampling discharge branch pipe 9, and is pushed out to the sampling discharge pipe 3 through the spiral rotation, and is filled into the sampling tank 4 directly below the outlet through the sampling discharge pipe 3.

[0054] When the corresponding weight is filled, the controller 8 controls the servo motor 2 to stop rotating, and the discharge stops. Then the controller 8 controls the sample transportation assembly line 7 to run for a set distance, so that the next empty sampling tank 4 runs to the sampling discharge pipe 3 directly below to wait for filling.

[0055] When the sampling tank 4 filled with material runs to the sensing area of the infrared sensor 5, the infrared sensor 5 sends a level signal to the controller 8, and the controller 8 controls the alarm lamp 6 to light up a red light and alarm, reminding manual sampling.

[0056] When the sampling tank 4 filled with material is manually taken away, the alarm lamp 6 lights up a green light and stops alarming, and the cycle continues.

[0057] 2. Temporary automatic sampling:

[0058] When the process requires taking materials according to a fixed bag number, only need to open the automatic powder sampling device of the utility model synchronously when the new energy battery positive electrode material packaging machine starts, the automatic powder sampling device enters a manual standby state, when the number of packaging bags reaches the first set sampling bag number, only need to press the physical sampling control button 10 manually, the controller 8 receives the signal and controls the servo motor 2 to rotate the corresponding weight circle number, the sample powder enters the small spiral conveying pipe 1 through the sampling discharge branch pipe 9, and then is pushed out to the sampling discharge pipe 3 through the spiral rotation, and is filled into the sampling small tank 4 directly below the outlet through the sampling discharge pipe 3;

[0059] When the corresponding weight is filled, the controller 8 controls the servo motor 2 to stop rotating, the discharge stops, and then the controller 8 controls the sample transportation assembly line 7 to run for a set distance, so that the next empty sampling small tank 4 is used to the sampling discharge pipe 3 directly below to wait for loading.

[0060] When the sampling small tank 4 filled with materials runs to the sensing area of the infrared sensor 5, the infrared sensor 5 sends a level signal to the controller 8, the controller 8 controls the alarm lamp 6 to light a red light and alarms, reminding manual sampling.

[0061] When the sampling small tank 4 filled with materials is taken manually, the alarm lamp 6 lights a green light and stops alarming, and the cycle is repeated.
