The rotating speeds corresponding to different gears of the peristaltic pump are different, the corresponding gears can be selected to set the forward rotating speed and the reverse rotating speed of the peristaltic pump before the blanking control device is started, in addition, the flow values corresponding to liquid in the conveying pipelines at different rotating speeds of the peristaltic pump can be measured in advance through experiments, the conveying pipelines with corresponding diameters and lengths are simultaneously selected to convey the liquid, and the length of the filling pipeline of the rear conveying pipeline when the peristaltic pump runs for the first preset time is determined according to the length of the pipeline. Specifically, a first flow value of the liquid in the transport pipe when the transport pipe is pre-filled is determined according to a preset forward rotation speed of the peristaltic pump, a second flow value of the liquid in the transport pipe when the transport pipe is back pumped is determined according to a preset reverse rotation speed of the peristaltic pump, further, a volume of the fill pipe when the transport pipe is pre-filled is calculated according to a determined length of the fill pipe and a pipe diameter, then the calculated volume of the fill pipe is divided by the first flow value to obtain a first preset time when the peristaltic pump is in forward operation, further, a volume of the overall transport pipe is calculated according to the length of the overall transport pipe and the pipe diameter, and the calculated volume of the overall transport pipe is divided by the second flow value to obtain a second preset time when the peristaltic pump is in reverse operation, as shown in fig. 3, the transport pipe 2 and the transport pipe 7 are respectively arranged between the peristaltic pump and the container and the feed opening, when the peristaltic pump operates for the first preset time, the filling pipeline length of the conveying pipeline is the sum of the filling pipeline length of the conveying pipeline 7 and the pipeline length of the conveying pipeline 2, and the pipeline length of the whole conveying pipeline is the sum of the pipeline length of the conveying pipeline 1 and the pipeline length of the conveying pipeline 2.

202. And controlling the peristaltic pump to operate positively for a first preset time based on the received blanking instruction so that the liquid fills at least part of the transportation pipeline.

For the embodiment of the invention, before the peristaltic pump is operated in the forward direction for quantitative blanking, whether the blanking device is at a designated position needs to be detected, two implementation modes are specifically provided in the embodiment of the invention, and whether the receiving device is at a preset position within a preset time period is detected based on a received blanking instruction; if the material receiving device is located at a preset position, controlling the peristaltic pump to operate in the forward direction for a first preset time; or after controlling the peristaltic pump to operate in the forward direction for a first preset time, detecting whether the material receiving device is at a preset position within a preset time period; and if the material receiving device is at a preset position, determining the quantitative blanking time of the positive operation of the peristaltic pump according to the blanking weight.

The material receiving device can be a material spoon, as shown in fig. 4, the material spoon 12 is arranged below a discharge port, a material spoon sensor 10 is arranged right in front of the material spoon 12, a detection lens 11 is arranged between the material spoon 12 and the material spoon sensor 10, and the material spoon sensor can be prevented from being corroded by liquid seasoning stained on the material spoon through the detection lens 11, so that the material spoon sensor is damaged, the detection precision of the material spoon sensor is reduced, if the material spoon sensor is an inductive sensor, when the material spoon containing metal is close to the inductive sensor, the inductive sensor can detect the material spoon by detecting the change of an inductive signal and output a detection signal; if this spoon sensor is photoelectric sensor, when the spoon is close to photoelectric sensor, the light wave that sends from photoelectric sensor can be reflected back by the spoon, can detect the spoon through the light wave that is reflected back to send detected signal, unloading controlling means can control the peristaltic pump operation after receiving this detected signal.

Specifically, before the peristaltic pump is operated in the forward direction for a first preset time, a photoelectric sensor is used for detecting whether the material spoon is at a preset position within a preset time period, if the material spoon is at the preset position within the preset time period, the peristaltic pump is controlled to operate for the first preset time so as to enable liquid to fill at least part of the conveying pipeline, and therefore the position of the material spoon is detected firstly and then the peristaltic pump is controlled to operate for the first preset time, so that the liquid in the conveying pipeline can be prevented from precipitating, or the liquid is left in the conveying pipeline for a long time to corrode the pipeline; the material spoon can be controlled to run for the first preset time and then detect the position of the material spoon, the time that a user waits for quantitative blanking after the material spoon is placed can be shortened, the material feeding feeling for the user is very fast, and the user experience is enhanced.

Further, after the peristaltic pump operates for a first preset time and liquid is filled in a transport pipeline, if the material receiving device is not located at a preset position within a preset time period, the peristaltic pump is controlled to operate reversely for a second preset time until the material receiving device is detected to be located at the preset position, and the peristaltic pump is controlled to operate normally for the first preset time; or if the receiving device is not at the preset position, acquiring the forward rotating speed and the reverse rotating speed corresponding to the peristaltic pump, and the pipeline diameter and the pipeline pumping length corresponding to the conveying pipeline; calculating a third preset time for the peristaltic pump to operate in the forward direction according to the forward rotation speed, the diameter of the pipeline and the pumping length of the pipeline; calculating fourth preset time for reverse operation of the peristaltic pump according to the reverse rotation speed, the diameter of the pipeline and the length of the pipeline during pumping back; and controlling the peristaltic pump to reversely operate for the fourth preset time until the material receiving device is detected to be at the preset position, and controlling the peristaltic pump to normally operate for the third preset time.

For the embodiment of the invention, when the material spoon is not at the preset position in the preset time period, the peristaltic pump can be controlled to reversely rotate to suck back the liquid in the conveying pipeline, the liquid is prevented from being deposited or corroded and blocking the conveying pipeline for a long time in the conveying pipeline until the material spoon is detected to be at the preset position, the peristaltic pump is controlled to forwardly operate to fill the conveying pipeline, and the forward operation time and the reverse operation time of the peristaltic pump are related; the other mode is that when the material spoon is not at the preset position, only part of liquid in the conveying pipeline is pumped back so as to reduce the time of the subsequent positive running of the peristaltic pump and quickly enter the quantitative blanking link, specifically, the pipe pumping back length when the material spoon is not at the preset position in the preset time period is firstly determined, the volume of the pumping back pipeline is calculated according to the determined pipe pumping back length and the pipe diameter, then the second flow value of the liquid in the conveying pipeline is determined according to the reverse rotating speed of the peristaltic pump, the fourth preset time of the reverse running of the peristaltic pump is calculated according to the second flow value and the volume of the pumping back pipeline, further, the first flow value of the liquid in the conveying pipeline is determined according to the positive rotating speed of the peristaltic pump, and the third preset time of the positive running of the peristaltic pump is calculated according to the first flow value and the volume of the pumping back pipeline, so that when the material spoon is not at the preset position, the peristaltic pump is operated in reverse to pump back the liquid and in forward to fill the liquid.

203. And determining the quantitative blanking time of the positive operation of the peristaltic pump according to the blanking amount, and controlling the operation of the peristaltic pump to finish the quantitative blanking according to the quantitative blanking time.

For the embodiment of the invention, in order to calculate the quantitative blanking time of the positive operation of the peristaltic pump, the embodiment of the invention provides two implementation modes, wherein one implementation mode specifically comprises the following steps: calculating a time required for the peristaltic pump to operate forward to liquid fill a transport tube based on the determined first flow value, the tube diameter, and the tube length; calculating the time difference between the time required for filling the transport pipeline with the liquid and the first preset time; according to the blanking amount and the first flow value, calculating quantitative blanking time of forward operation of the peristaltic pump; and adding the quantitative blanking time and the time difference value, and controlling the peristaltic pump to operate according to the addition result to finish quantitative blanking.

If the transport pipeline is filled with liquid after the peristaltic pump operates positively for the first preset time, calculating quantitative blanking time of the peristaltic pump operating positively according to the blanking amount and the first flow value directly, and controlling the peristaltic pump to operate according to the quantitative blanking time to finish quantitative blanking; if only part of the pipelines in the conveying pipeline are filled after the peristaltic pump is operated forwards for the first preset time, the peristaltic pump needs to be operated for one more time deviation during quantitative blanking so as to fill the unfilled residual pipelines with liquid and ensure the blanking liquid precision.

Further, the blanking rotational speed of the peristaltic pump may be greater than the forward rotational speed of the peristaltic pump when filling the transport conduit, and another embodiment specifically includes: obtaining a corresponding blanking rotating speed of the peristaltic pump and the length of a residual pipeline which is not filled with liquid in the conveying pipeline after the peristaltic pump operates for a first preset time; determining the flow value of liquid in a transportation pipeline during blanking according to the blanking rotating speed; calculating the time for filling the residual pipeline with the liquid operated by the peristaltic pump according to the flow value of the liquid in the transport pipeline during blanking, the length of the residual pipeline and the diameter of the pipeline; calculating the quantitative blanking time of the positive operation of the peristaltic pump according to the flow value of the liquid in the conveying pipeline during blanking and the blanking amount; and adding the quantitative blanking time and the time for filling the residual pipelines, and controlling the peristaltic pump to operate according to the addition result to finish the quantitative blanking.

Specifically, the flow value of liquid in the conveying pipeline during blanking is determined according to the blanking rotating speed corresponding to the peristaltic pump, meanwhile, the length of the residual pipeline which is not filled in the conveying pipeline is determined according to the length of the conveying pipeline and the length of the filling pipeline, the time for filling the residual pipeline during operation of the peristaltic pump is calculated according to the length of the residual pipeline, the diameter of the pipeline and the flow value of the liquid in the conveying pipeline, then, the time for filling the residual pipeline is added with the quantitative blanking time, and the forward operation of the peristaltic pump is controlled according to the addition result to finish the quantitative blanking. Therefore, by adopting different rotating speeds of the peristaltic pumps, the quantitative blanking efficiency can be improved, and the quantitative blanking time can be shortened.
