[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 As shown, at least one embodiment provides a real-time weighing liquid filling device, which includes: a filling platform 1; an automatic weighing platform 2, which is arranged on the filling platform 1 and is suitable for holding a filling barrel 6 to obtain and send the weight data of the filling barrel 6 in real time; a lifting mechanism 3, which is arranged on the filling platform 1; a filling nozzle 4, which is installed on the lifting mechanism 3 and is suitable for being close to the barrel mouth of the filling barrel 6 through the lifting mechanism 3; a feeding component 5, which is connected to the filling nozzle 4; and a control module, which is electrically connected to the automatic weighing platform 2 and the feeding component 5 respectively; wherein a dust cover 41 is provided on the filling nozzle 4, which is suitable for covering the barrel mouth of the filling barrel 6 during filling; the control module is suitable for controlling the feeding component 5 to fill materials into the filling barrel 6, and controlling the feeding component 5 to stop filling materials when the acquired weight data reaches a threshold value.

[0030] In some embodiments, the automatic weighing platform 2 can be but is not limited to an electronic scale, and the electronic scale is electrically connected to the control module; during filling, the filling barrel 6 is placed on the automatic weighing platform 2, and after placement, the automatic weighing platform 2 is operated to reset to zero (i.e., deduct the tare weight), and then the filling nozzle 4 is lowered to a height close to the barrel mouth of the filling barrel 6 for filling. At this time, the automatic weighing platform 2 can obtain the weight of the raw materials in the filling barrel 6 in real time, and send the obtained weight data to the control module in real time. Compared with the existing method of quantitative filling and then weighing, the weight data feedback is more timely; wherein, the control module can be but is not limited to using PLC.

[0031] In some embodiments, the feeding assembly 5 includes a rotor pump 51, one end of which is connected to the silo, and the other end is connected to the filling nozzle 4 through a hose. Compared with the existing method of using a cylinder as a driving source, the rotor pump 51 in this embodiment can make the word filling amount not affected by the cylinder capacity, thereby obtaining a wider range of filling amounts; at the same time, the control module is electrically connected to the rotor pump 51. During filling, when the weight data obtained by the control module reaches a threshold, the control module controls the rotor pump 51 to stop feeding. This embodiment realizes real-time weighing while filling through the mutual cooperation of the control module, the rotor pump 51, and the automatic weighing platform 2, thereby improving the filling yield and reducing rework and scrap.

[0032] like Figure 2 As shown, in some embodiments, the lifting mechanism 3 includes: a lifting component 31 and a mounting block 32, and the filling nozzle 4 is arranged on the mounting block 32; the lifting component 31 includes: two guide columns 311, which are arranged on the filling platform 1, and the upper ends of the two guide columns 311 can be connected by a connecting block, so that the two guide columns 311 are more stable; a lifting screw 312, which is arranged on the filling platform 1, parallel to the guide column 311, and the upper part can pass through the connecting block, which is more stable; a handwheel 313, which is connected to the lifting screw 312, is used to drive the lifting screw 312 to rotate; wherein the mounting block 32 is penetrated on the guide column 311 and the lifting screw 312; and the handwheel 313 is suitable for driving the lifting screw 312 to rotate so as to lift and lower the mounting block 32; specifically, when the filling barrel 6 is placed on the automatic weighing platform 2, the operator turns the handwheel 313 to lower the filling nozzle 4 on the mounting block 32 to a height close to the barrel mouth of the filling barrel 6.

[0033] like Figure 3 As shown, in some embodiments, the discharge port 42 of the filling nozzle 4 is arranged downward; the dust cover 41 is sleeved on the discharge port 42 of the filling nozzle 4; since the barrel mouth of the filling barrel 6 is arranged upward, the discharge port 42 of the filling nozzle 4 is arranged downward to adapt to it, and is close to the barrel mouth of the filling barrel 6 during filling.

[0034] In some embodiments, the lower portion of the discharge port 42 is inclined inward, and this inclined surface can be adapted to filling barrels 6 of different calibers.

[0035] In some embodiments, the side wall of the dust cover 41 is inclined; specifically, it is gradually inclined outward from top to bottom, which can not only prevent foreign objects from falling into the filling barrel 6, but also prevent foreign objects from accumulating on the dust cover 41.

[0036] In some embodiments, the bottom surface of the discharge port 42 protrudes from the bottom surface of the dust cover 41; specifically, the inclined side wall of the discharge port 42 protrudes from the bottom surface of the dust cover 41. This arrangement can prevent the dust cover 41 from affecting the close proximity of the discharge port 42 to the barrel mouth of the filling barrel 6.

[0037] In summary, the real-time weighing liquid filling equipment realizes real-time weighing while filling through the cooperation of the control module, the rotor pump 51 and the automatic weighing platform 2, thereby improving the filling yield rate and reducing rework and scrap.
