The diameter of the film stretching rod 22 is the same as the diameter of the battery; the battery fixing mechanism 3 is used to fix the battery at the film sleeving station; the film cutting mechanism 4 is used to separate the film sleeved on the battery from the film on the film stretching rod 22; the film feeding mechanism includes a driving wheel assembly. The driving wheel assembly includes two driving wheels 6 arranged oppositely on the circumferential side of the film stretching rod 22 and a first driving member for driving the two driving wheels 6 to rotate in opposite directions. The axial direction of the driving wheel 6 is perpendicular to the axial direction of the film stretching rod 22. Thus, during film sleeving, the film supply mechanism 1 supplies the strip-shaped film to the film stretching plate 21. The strip-shaped film is inserted into the inner side of the strip-shaped film through the film stretching plate 21 to expand the strip-shaped film, and then further expanded through the conical top end of the film stretching rod 22 until it is sleeved on the film stretching rod 22. At this time, the expanded film is between the driving wheel 6 and the film stretching rod 22. The two driving wheels 6 are driven by the first driving member to rotate in opposite directions to push the film sleeved on the film stretching rod 22 downward until it is sleeved on the battery at the film sleeving station, and then cut by the film cutting mechanism 4 to separate the film sleeved on the battery from the film on the film stretching rod 22, completing the film sleeving process. There is no need to pre-cut the film. First, directly sleeve the film and then cut it, which is convenient and fast and improves the film sleeving efficiency.

[0042] Further optimized, reference Figure 1 As shown in the figure, it further includes a mounting seat 8 and a fourth driving member. The film sleeving bracket 7 is slidably arranged on the mounting seat 8. The fourth driving member is used to drive the film sleeving bracket 7 to move up and down on the mounting seat 8. In this way, the film sleeving bracket 7 is driven to move up and down to adjust the film sleeving height to complete the film sleeving, and it can adapt to the film sleeving of batteries of different specifications (the corresponding film supporting rod 22 and film supporting plate 21 can be replaced correspondingly).

[0043] The working principle of the present utility model: When sleeving the film, the film feeding mechanism 1 supplies the strip film to the film supporting plate 21. The strip film is inserted into the inner side of the strip film through the film supporting plate 21 to expand the strip film, and then further expanded through the conical top of the film supporting rod 22 until it is sleeved on the film supporting rod 22. At this time, the expanded sleeved film is between the driving wheels 6 and the film supporting rod 22. The two driving wheels 6 are driven by the first driving member to rotate in opposite directions, and the film sleeved on the film supporting rod 22 is pushed downward until it is sleeved on the battery at the film sleeving station. Then, it is cut by the film cutting mechanism 4 to separate the film sleeved on the battery from the film on the film supporting rod 22, completing the film sleeving process. There is no need to pre-cut the film. First, sleeve the film directly and then cut it, which is convenient and fast and improves the film sleeving efficiency.
