[0022] When the reaction material feeding device is used, the fixed frame 1 is placed on the ground on the side of the feeding port of the reaction kettle, the fixed frame 1 is close to the reaction kettle, the reaction material is added into the feeding mechanism on the upper side of the lifting frame 9 close to the lower sprocket 6, the first servo motor 8 drives the lower sprocket 6, the upper sprocket 5 and the chain 7 to rotate, the chain 7 lifts the feeding mechanism on the lifting frame 9 to a certain height, then the linear driving mechanism drives the moving frame 2 and the feeding mechanism above the moving frame 2 to horizontally approach the feeding port of the reaction kettle, the feeding mechanism feeds the reaction kettle, and the first batch of feeding is completed, at this time, the feeding mechanism on the other side is lowered to the lower side, the second batch of feeding is completed by repeating the above operation, and the two feeding mechanisms are alternately used to complete continuous batch feeding.

[0023] As Figure 3 The linear driving mechanism comprises a driving block 11 and a driving screw 12, the driving block 11 is fixedly connected with the bottom of the moving frame 2, the driving screw 12 is rotatably connected with the fixed frame 1, one end of the driving screw 12 is fixedly connected with a second servo motor 13, and the second servo motor 13 is fixed on the fixed frame 1. The second servo motor 13 drives the driving screw 12 to rotate, so as to drive the driving block 11 to move horizontally and linearly.
