[0037] Reference Figures 1 to 4 A step-by-step weighing and feeding structure according to the first aspect of the utility model comprises:

[0038] The feeding assembly 100 is provided with at least two groups to convey at least two different liquid materials. The feeding assembly 100 comprises an incoming pipe 110, a liquid pump 120 and a delivery pipe 130. The incoming pipe 110 and the delivery pipe 130 are respectively connected to the input end and the output end of the liquid pump 120.

A feed hole 321 is provided at the top of the weighing container 320, and the bottom of the second vertical pipe 223 is penetrated in the feed hole 321. By setting the weighing container 320 as a container with shielding in all dimensions and opening the feed hole 321 at the top for penetrating the second vertical pipe 223 for feeding, the contact between the internal space of the weighing container 320 and the external environment can be effectively reduced.

The discharge valve 323 is used to control the on-off of the discharge pipe 322.

[0041] Preferably, the weighing container 320 is connected to the weighing sensor 310 via a weighing bracket.

[0042] One end of the material inlet pipe 110 away from the liquid pump 120 is connected to an external material storage container. The working process of the step-by-step feeding structure of the utility model is as follows:

[0043] Material selection and connection: before feeding, the connection motor 230 drives the second vertical pipe 223 to rotate through the transmission mechanism 240, so that the first vertical pipe 221 rotates around the central axis of the second vertical pipe 223 until the top of the first vertical pipe 221 is connected to the bottom of the corresponding material delivery pipe 130, thereby achieving the connection between the first vertical pipe 221 and the corresponding material delivery pipe 130, that is, achieving the connection between the connection assembly 200 and the corresponding material feeding assembly 100;

[0044] Pumping weighing, the liquid pump 120 in the feeding assembly 100 corresponding to the connecting assembly 200 works, and the corresponding liquid material is pumped to the feeding pipe 130, so that the liquid material enters the weighing container 320 through the connecting pipe 220, and the weighing sensor 310 measures the weight of the liquid material inside the weighing container 320. When the weighing sensor 310 measures that the weight of the liquid material inside the weighing container 320 reaches a preset value, a shutdown signal is generated and sent to the corresponding liquid pump 120 through the control system to control the liquid pump 120 to stop pumping;

[0045] Feeding: after the liquid pump 120 in the corresponding feeding assembly 100 is shut down, the discharge valve 323 is opened to conduct the discharge pipe 322, and the weighed liquid material in the weighing container 320 falls through the delivery pipe 130 to realize the feeding action;

[0046] After the feeding of the liquid material is completed, a feeding assembly 100 for conveying another liquid material is selected, and the above steps of material selection, connection, pumping, weighing and feeding are repeated to achieve weighing and feeding operations of different liquid materials.

[0047] By setting up multiple groups of feeding components 100 for conveying different liquid materials respectively, the connection between the weighing component 300 and different feeding components 100 can be realized through the rotatable zigzag connecting pipe 220 in the connecting component 200, and the connecting motor 230 drives the second vertical pipe 223 to rotate through the transmission mechanism 240. Under the connection action of the transition pipe 222, the first vertical pipe 221 rotates around the central axis of the second vertical pipe 223 to connect the corresponding conveying pipe 130, and the second vertical pipe 223 is inserted into the feeding hole 321. The connecting pipe 220 can realize The connection between the feed pipe 130 and the weighing container 320 is achieved by adjusting the connecting component 200 in different time periods according to actual application requirements to connect the weighing container 320 and the corresponding feed pipe 130, and weighing the liquid material through the weighing component 300. It is possible to implement step-by-step weighing and feeding operations for different liquid materials in different time periods. The overall structure is simple and reliable. One set of weighing components 300 can be used in conjunction with multiple sets of feeding components 100. The overall structure has low investment cost, high weighing and feeding efficiency, high weighing accuracy, and can effectively save labor costs.

[0048] It is understandable that the central axis of the first riser 221 and the central axis of the feed pipe 130 are both perpendicular to the horizontal plane. By arranging the first riser 221 and the feed pipe 130 in an upright manner, the design difficulty of the overall structural layout can be effectively reduced.

[0049] It is understandable that the inner diameter of the first riser 221 is equal to the outer diameter of the feed pipe 130 , so that the first riser 221 can be completely connected to the feed pipe 130 , thereby effectively ensuring that the liquid material output from the feed pipe 130 can be accurately input into the first riser 221 .

[0050] It can be understood that the transmission mechanism 240 includes a gear ring 241 and a driving gear 242. The outer ring of the gear ring 241 is provided with teeth.

The driving gear 242 is meshed and connected with the gear ring 241. When the docking motor 230 is working, it drives the driving gear 242 to rotate. The driving gear 242 drives the gear ring 241 to rotate, thereby driving the second vertical pipe 223 to rotate synchronously, which can make full use of the space for layout design.

[0051] Specifically, the transmission mechanism 240 also includes a transmission gear, and the driving gear 242 is meshed and connected with the gear ring 241 through the transmission gear. By adding the transmission gear, the design restrictions of the connection motor 230 can be effectively reduced, and the design difficulty of this step-by-step weighing and feeding structure can be effectively reduced.

[0053] It can be understood that the weighing component 300 also includes a wind knife 330, which utilizes the power of compressed air. The compressed air is input into the wind knife 330, and then the compressed air is adjusted to be output according to the geometric shape of the wind knife 330, thereby forming a high-intensity, large airflow impact wind curtain. The wind knife 330 is arranged at the top of the weighing container 320, and the blade of the wind knife 330 is downward toward the inner wall of the weighing container 320. When the wind knife 330 is working, it is used to generate high-pressure gas to push the residual liquid material on the inner wall of the weighing container 320 downward, thereby effectively improving the feeding accuracy of the weighing container 320.
