[0037] Working principle: in actual use, personnel can be through the support leg 14 to set up raw material cylinder 1 in the battery plastic shell production shell mold at the conveying belt, then can be added to the storage cavity 3 through the feed inlet 7 plastic melt used in production, convenient for subsequent use, then through the operation of the first motor 5 can drive the stirring blade 4 to continuously stir the plastic melt inside, thereby avoiding the settlement caused by standing and solidification, ensuring the smoothness of subsequent feeding and the use quality of the melt, ensuring the quality of the battery plastic shell produced in the subsequent production, and at the same time of stirring, the storage cavity 3 can be continuously heated by the heating plate 2, which can ensure the stability of the temperature and avoid the solidification of the plastic melt caused by the temperature drop. Then, when subsequent feeding is needed, the second motor 19 can drive the adjusting disc 8 to rotate, and when the discharge hole 10 on the surface of the adjusting disc 8 is aligned with the discharge hole 10 on the surface of the fixed disc 11, the melt in the storage cavity 3 can be smoothly discharged and fall into the flow guide pipe 12. By controlling the rotation speed of the adjusting disc 8, the addition speed of the melt can be controlled. When the melt falls into the flow guide pipe 12, the support arm 13 on the surface of the flow guide pipe 12 will press the load cell 15, and the load cell 15 can detect the amount of added melt. Then, through the operation of the air cylinder 20, the sealing plate 18 can move in and out as a whole, and the melt in the flow guide pipe 12 can be smoothly discharged and flow into the flow divider 16. Through multiple flow dividers 16, the plastic shell can be formed.

The longer the discharge path, the thicker the pipe, and the shorter the discharge path, the thinner the pipe. In this way, the amount of melt added per unit time can be more uniform, thereby avoiding errors that are too large to cause different feeding times for shell molds at different positions, thereby affecting the overall feeding efficiency. The device has the advantages of multi-station feeding, high feeding efficiency and high feeding precision.
