All the stirring blades 330 are located below the horizontal position of the discharge pipe 250.

[0036] The working process of the liquid mixing device for automatic material counting in the embodiment of the utility model is as follows:

[0037] Material preparation: storing various liquid materials to be mixed in various storage tanks 210 manually or in other ways;

[0038] Material metering: the liquid pump 221 starts to input the liquid material in the storage tank 210 into the metering tank 230. After a preset time, the liquid pump 221 stops working, and the liquid material in the metering tank 230 located above the top of the first reflux pipe 240 flows into the storage tank 210 through the first reflux pipe 240 inclined downward, so that the liquid level in the metering tank 230 can finally be flush with the top of the first reflux pipe 240, thereby making the liquid material in the metering tank 230 reach a preset volume, and the metering is completed;

[0039] Material delivery: After the material delivery valve 251 is opened, the material delivery pipe 250 is connected so that the liquid material measured in the material metering tank 230 is delivered to the mixing tank 100;

[0040] Mixing: After various liquid materials are input into the mixing tank 100 through material metering and feeding, the motor 310 drives the mixing blade 330 to rotate through the rotating shaft 320 to mix the various liquid materials in the mixing tank 100.

[0041] A sufficient amount of liquid material is pumped from the storage tank 210 to the metering tank 230 by the liquid pump 221, and the first reflux pipe 240 is arranged to be inclined at the horizontal plane to connect the metering tank 230 and the storage tank 210 with a height difference. The liquid material in the metering tank 230 and above the top of the first reflux pipe 240 can flow into the storage tank 210 through the downwardly inclined first reflux pipe 240, so that the liquid level of the liquid material in the metering tank 230 is flush with the height of the top of the first reflux pipe 240, so that a measured amount of liquid material is collected in the metering tank, which can effectively save the steps of manual weighing and metering, can effectively save labor costs, and has high metering accuracy and efficiency, which can effectively improve the quality of products obtained by mixing and processing liquid materials. The liquid mixing device has high mixing production efficiency and a high degree of automation, and the structure of the liquid mixing device is simple and reliable.

[0042] It can be understood that one end of the feed pipe 220 connected to the metering tank 230 is located above the top of the first reflux pipe 240, which can ensure that the feed pipe 220 is located above the measured liquid material in the metering tank 230, thereby avoiding the feed pipe 220 from affecting the metering of the liquid material in the metering tank 230, and can effectively improve the accuracy of the liquid material metering in the metering tank 230, thereby improving the quality of the mixed product.

[0043] It can be understood that a first sensor 241 is provided in the first reflux pipe 240, and the first sensor 241 is electrically connected to the electrical control end of the liquid pump 221 through the control system. The first sensor 241 is used to detect the flow of liquid in the first reflux pipe 240. When the first sensor 241 detects that liquid is flowing in the first reflux pipe 240, a shutdown signal is generated and sent to the liquid pump 221 through the control system, thereby controlling the liquid pump 221 to stop working.

[0044] The first reflux pipe 240 is monitored by detecting the flow of liquid, and the liquid pump 221 pumps the liquid material to the metering tank 230. When the liquid level in the metering tank 230 exceeds the top of the first reflux pipe 240, the liquid material will flow from the first reflux pipe 240 into the storage tank 210. At this time, the first sensor 241 detects that there is liquid flowing in the first reflux pipe 240 and sends a shutdown signal to the liquid pump 221 through the control system to control the liquid pump 221 to stop working, thereby realizing a more automated metering action.

[0045] Specifically, the first sensor 241 is a liquid flow sensor.

[0046] It can be understood that the material metering input component 200 also includes a second return pipe 260 inclined to the horizontal plane, the bottom end of the second return pipe 260 is connected to the storage tank 210, the top end of the second return pipe 260 is connected to the tank wall of the material metering tank 230, the top end of the second return pipe 260 is located below the top end of the first return pipe 240, and a feed control valve 261 is provided in the second return pipe 260. The feed control valve 261 is used to control the on-off of the second return pipe 260. When the feed control valve 261 is opened and unobstructed, the liquid level of the liquid material in the material metering tank 230 can be adjusted to be flush with the top end of the second return pipe 260; when the feed control valve 261 is closed and blocked, the liquid level of the liquid material in the material metering tank 230 is adjusted according to the top end of the first return pipe 240.

[0047] The production of some products requires adding the same liquid material at different times. The same metering tank 230 is used to quantitatively measure and input the same liquid material at different times, which can meet the production needs of different products and has strong versatility.

[0048] It can be understood that a second sensor 262 is provided in the second return pipe 260, and the second sensor 262 is electrically connected to the electrical control end of the liquid pump 221 through the control system. The second sensor 262 is used to detect the flow of liquid in the second return pipe 260. When the second sensor 262 detects that liquid is flowing in the second return pipe 260, a shutdown signal is generated and sent to the liquid pump 221 through the control system, thereby controlling the liquid pump 221 to stop working.

[0049] When it is necessary to measure the volume corresponding to the top of the second reflux pipe 260, the feed control valve 261 is opened to make the second reflux pipe 260 unobstructed, and the second reflux pipe 260 is monitored by detecting the flow of liquid. The liquid pump 221 pumps the liquid material to the metering tank 230. When the liquid level in the metering tank 230 exceeds the top of the second reflux pipe 260, the liquid material will flow from the second reflux pipe 260 into the storage tank 210. At this time, the second sensor 262 detects that there is liquid flowing in the second reflux pipe 260 and sends a shutdown signal to the liquid pump 221 through the control system to control the liquid pump 221 to stop working, so as to achieve a more automated metering action. The second sensor 262 can be set as a liquid flow sensor.

[0050] It is understandable that a discharge valve 111 is provided in the discharge pipe 110, and the discharge valve 111 is used to control the on-off of the discharge pipe 110 to output the product obtained after stirring and mixing.

[0051] It can be understood that the bottom end of the feed pipe 220 is connected to the bottom of the storage tank 210, which can effectively improve the reliability of the liquid pump 221 collecting the liquid material in the storage tank 210 through the feed pipe 220. During cleaning, the cleaning agent can be added to the storage tank 210, and then the cleaning agent in the storage tank 210 can be completely injected into the metering tank through the liquid pump 221 and reach the mixing tank 100 for cleaning. The cleaning operation is convenient and reliable.

[0052] It can be understood that a bracket 120 is provided at the bottom of the mixing tank 100, and the storage tank 210 is connected to the bracket 120. The mixing tank 100 and the storage tank 210 are supported by the bracket 120 so as to set the discharge pipe 110 and facilitate the setting of the supply pipe 220 to connect to the bottom of the discharge tank.
