[0025] Referring to Figure 1 and Figure 2 , a feeding device includes an industrial robot arm 1, a first material proportioning assembly 3 and a second material proportioning assembly 5. The first material proportioning assembly 3 and the second material proportioning assembly 5 are respectively arranged on both sides of the industrial robot arm 1. An empty bag collection assembly 4 is arranged in front of the industrial robot arm 1. The first material proportioning assembly 3, the empty bag collection assembly 4 and the second material proportioning assembly 5 are all arranged within the conveying range of the robot arm 1. A suction cup mounting seat 7 is installed at the free end of the robot arm 1. A vacuum suction cup 6 is installed at the lower end of the suction cup mounting seat 7. A material bag auxiliary fixing assembly 2 is arranged outside the vacuum suction cup 6. The material bag auxiliary fixing assembly 2 is connected to the suction cup mounting seat 7.

[0026] In this embodiment, both the first material proportioning assembly 3 and the second material proportioning assembly 5 are within the conveying range of the robot arm 1. The robot arm 1 drives the vacuum suction cup 6 to convey the material bag to the designated position.

[0027] Obviously, based on the above, the device realizes double-station mechanized feeding.

[0028] In this embodiment, referring to Figure 1, the first material proportioning component 3 includes a material weighing component 31, a batching tank 32, and a bag-breaking component 33. A first mounting frame 34 is installed outside the batching tank 32. The bag-breaking component 33 is installed at the upper end of the first mounting frame 34. A feed hopper is arranged below the bag-breaking component 33. The feed hopper is connected to the first mounting frame 34, and the outlet of the feed hopper is connected to the inlet of the batching tank 32. The material weighing component 31 is arranged in front of the first mounting frame 34.

[0029] Obviously, based on the above, the device monitors the mass of the material grabbed each time through the material weighing component 31. When the material is grabbed above the bag-breaking component 33, the reduced mass of the weighing platform 313 is the mass of the material grabbed this time. The material completes the bag-breaking process through the action of the bag-breaking component 33. After the solid nickel nitrate falls into the feed hopper, it enters the batching tank, realizing the mechanized transportation of solid nickel nitrate.

[0030] In this embodiment, the first material proportioning component 3 and the second material proportioning component 5 have the same structure;

[0031] Obviously, based on the above, the second material proportioning component 5 can also realize the function of the first material proportioning component 3.

[0032] In this embodiment, referring to Figure 3 , the material weighing component 31 includes a second mounting frame 312, a weighing platform 313, and a material bag positioning frame 314. The weighing platform 313 is arranged above the second mounting frame 312. A through hole is opened in the middle of the second mounting frame 312.

The upper ends of the guide rods 315 are connected to the weighing platform 313. The material bag positioning frame 314 is installed at the upper end of the weighing platform 313.

[0033] Obviously, based on the above, after multiple groups of material bags are placed above the weighing platform 313, the weighing platform 313 monitors the mass of multiple groups of material bags in real time. When the feeding process starts, every time the industrial robot arm 1 completes the transportation of a material bag, the second air cylinder 311 rises by a preset length according to a preset program to ensure that the industrial robot arm 1 grabs the material bag at a specified position.

[0034] In this embodiment, referring to Figure 4 , the bag-breaking component 33 includes four groups of third air cylinders 331 and four groups of blades 333.

The telescopic end of each group of third air cylinders 331 is connected to a group of blades 333 through a blade traction rod 332.

[0035] Obviously, based on the above, the blade 333 repeatedly moves through the third cylinder 331 to perform the bag-breaking process on the surface of the material bag.

[0036] In this embodiment, referring to Figure 2 , the material bag auxiliary fixing assembly 2 includes two groups of mounting rods 22, four groups of pressing blocks 23 and four groups of pressing bars 25. The two groups of mounting rods 22 are symmetrically arranged on both sides of the suction cup mounting seat 7 and are fixed to the suction cup mounting seat 7 through the connecting rod 21.

A bag body fixing needle is slidably installed inside the needle mounting groove. A first cylinder 24 is installed on the side of the needle mounting groove away from the suction cup mounting seat 7. The telescopic end of the first cylinder 24 is connected to the bag body fixing needle.

[0037] Obviously, based on the above, by adjusting the relative position of the pressing bar 25 and the mounting rod 22, the pressing bar 25 is located at the edge close to the material bag. The central part of the material bag is fixed by the vacuum suction cup 6, and the four corners of the material bag are fixed by the bag body fixing needles driven by the first cylinder 24.
