Technical Field

[0001] The utility model belongs to the technical field of lithium battery positive electrode material production, and more specifically, particularly relates to a lithium battery positive electrode material production feeding device. Background Art

[0002] The main components of lithium batteries include electrolyte, isolation materials, positive and negative electrode materials, etc. The positive electrode material accounts for a large proportion, because the performance of the positive electrode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost of the battery.

[0003] The existing positive electrode material feeding method is mostly to manually pour the positive electrode material into the screw feeder, and then use the screw feeder to transport the positive electrode material to the mixing barrel. When the operator pours the positive electrode material into the screw feeder, the powdered positive electrode material will fly to the outside of the screw feeder, and the operator is likely to inhale the positive electrode material into the body, thereby endangering the operator's health. Therefore, in view of this, the existing structure and defects are studied and improved, and a lithium battery positive electrode material production feeding device is provided, in order to achieve a more practical purpose.

[0026] A dust cover 10 is rotatably connected to one side of the dust removal box 5 through a hinge to prevent the flying positive electrode material from escaping from the dust removal box 5 without being completely absorbed.

[0027] A handle 12 is fixedly mounted on one side of the dust cover 10 to facilitate an operator to open and close the dust cover 10 .

[0028] Among them, both sides of the dust removal box 5 are rotatably connected to the gas spring 11 through a connecting rod 1, and connecting frames are fixedly installed on both sides of the dust cover 10. The two groups of connecting frames are rotatably connected to the other end of the gas spring 11 through two groups of connecting rods 2 respectively.
