The tin bar box 1 is provided with a tin bar lifting motor 13, and the output shaft of the tin bar lifting motor 13 is provided with a transmission device between the first rotating shaft 11 or the second rotating shaft 12. The tin bar lifting motor 13 can drive the rotating shaft 11 or the second rotating shaft 12 through the transmission device, and the front side and the rear side of the tin bar box 1 are respectively provided with front side opening and rear side opening. The tin bar box 1 is provided with a box door 14 at the front side opening thereof, and the tin bar box 1 is provided with a tin bar conveying device 5 at the rear side wall thereof. The tin bar conveying device 5 includes a conveying synchronous belt 55, and the rear side opening of the tin bar box 1 is provided with a flow guide plate 6 for guiding the tin bar on the tin bar box 3 to the conveying synchronous belt 55. In specific application, after the box door 14 is opened, the tin bar 9 to be conveyed is placed in the tin bar box 3 in the inner cavity of the tin bar box 1, and the tin bar box 3 has a plurality of tin bars 9. After starting work, the tin bar lifting motor 13 drives the first rotating shaft 11 or the second rotating shaft 12 to rotate through the transmission device, the first rotating shaft 11 or the second rotating shaft 12 drives the chain 23 to rotate, further, the chain 23 drives the tin bar box 3 close to the front side opening, and synchronously, the tin bar box 3 close to the rear side of the tin bar box 1 descends, completing the lifting work of the tin bar 9. When the tin bar box 3 reaches the highest point and rotates downward, the tin bar 9 slowly falls to the bottom of the previous tin bar box 3, and the back plate 15 of the tin bar box 1 is used as a tin bar limiting part. When the tin bar box 3 reaches the radius range of the second sprocket 22, the gap between the tin bar box 3 and the back plate 15 becomes larger and larger, and the gap between the back plate 15 and the tin bar box 3 becomes larger and larger.

The tin strip lifting motor 13 can drive the first rotating shaft 11 or the second rotating shaft 12 to rotate through the driving sprocket 41, the transmission chain 43, and the driven sprocket 42. In the embodiment, the tin strip lifting motor 13 drives the first rotating shaft 11 to rotate through the driving sprocket 41, the transmission chain 43, and the driven sprocket 42. The first rotating shaft 11 drives the first sprocket 21 to rotate, and the first sprocket 21 drives the chain 23 to make a rotary motion. In the process of making a rotary motion, the chain 23 synchronously drives the tin strip box 3 to make a lifting or descending action, thereby completing the lifting and descending work of the tin strips 9.
