[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-2 A screening device for processing negative electrode materials of lithium batteries comprises a screening device 1, a screen 2 is arranged inside the screening device 1, a feed hopper 3 is fixed on the screening device 1, and the feed hopper 3 is arranged opposite to the screen 2, and a bracket 4 is installed at the top of the feed hopper 3.

[0021] An intermittent material discharge component is provided on the feed hopper 3, and the intermittent material discharge component includes a motor 51, a rotating shaft 52, a rotating plate 53, a fixed plate 54, two material discharge ports 55 and an opening 56. The motor 51 is installed on the bracket 4, one end of the rotating shaft 52 is connected to the output shaft of the motor 51, the fixed plate 54 is fixed to the inner surface of the feed hopper 3, the rotating plate 53 is placed directly above the fixed plate 54, the rotating shaft 52, the rotating plate 53, the fixed plate 54 and the feed hopper 3 are coaxially arranged, the rotating plate 53 and the fixed plate 54 are in contact with each other, the outer surface of the rotating plate 53 and the inner surface of the feed hopper 3 are in contact with each other, the outer surface of the fixed plate 54 and the inner surface of the feed hopper 3 are in contact with each other, the two material discharge ports 55 are respectively opened on the rotating plate 53 and the fixed plate 54, the opening 56 is opened in the middle position of the fixed plate 54, the rotating plate 53 is fixedly sleeved on the rotating shaft 52, and the rotating shaft 52 passes through the opening 56, and The rotating shaft 52 and the opening 56 do not contact each other. When the two discharge ports 55 overlap each other, the raw materials will fall onto the screen 2 through the two discharge ports 55. When the two discharge ports 55 are rubbed apart from each other, the raw materials will temporarily accumulate on the feed hopper 3. Based on the above process, the raw materials will periodically fall onto the screen 2 to realize the function of intermittent discharge. This design can prevent a large amount of raw materials from falling onto the screen 2 in a short period of time. During the falling of the raw materials, the screen 2 only needs to screen and process a part of the raw materials to avoid the clogging of the screen 2 by the raw materials, thereby ensuring the normal operation of the screening device 1. A connecting plate 6 is fixed to the bottom end of the rotating shaft 52, and the connecting plate 6 is placed directly above the screen 2. When the connecting plate 6 rotates, it can evenly spread the raw materials accumulated on the screen 2 on the screen 2 to avoid the raw materials from accumulating in the middle of the screen 2, so that the raw materials are evenly distributed on the screen 2, thereby improving the screening efficiency of the screen 2 for the raw materials.

[0022] The specific working principle of the utility model is as follows:

[0023] When the screening device for processing negative electrode materials of lithium batteries proposed in the utility model is in use, the staff starts the motor 51 and pours the raw materials into the inside of the feed hopper 3. When the motor 51 is running, it can drive the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, it can drive the rotating plate 53 to rotate. During the rotation of the rotating plate 53, the two discharge ports 55 will overlap and misalign periodically. When the two discharge ports 55 overlap each other, the raw materials will fall on the screen 2 through the two discharge ports 55. When the two discharge ports 55 are rubbed apart from each other, the raw materials will temporarily accumulate on the feed hopper 3. Based on the above process, the raw materials will fall onto the screen 2 periodically to realize the function of intermittent feeding. This design can prevent a large amount of raw materials from falling onto the screen 2 in a short period of time. During the falling period of the raw materials, the screen 2 only needs to screen and process a part of the raw materials to avoid the clogging of the screen 2 by the raw materials, thereby ensuring the normal operation of the screening device 1.

[0024] In addition, a connecting plate 6 is fixed to the bottom end of the rotating shaft 52. When the rotating shaft 52 rotates, it can also drive the connecting plate 6 to rotate. When the connecting plate 6 rotates, it can evenly spread the raw materials accumulated on the screen 2 on the screen 2 to avoid the raw materials from accumulating in the middle of the screen 2. The raw materials are evenly distributed on the screen 2, thereby improving the screening efficiency of the screen 2 for the raw materials.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
