The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the utility model. However, those skilled in the art will appreciate that the technical solution of the utility model can be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted.

As shown in Figure 2, the utility model discloses a knife shaft positioning mechanism for a lithium battery aluminum foil slitting machine, which includes a front head seat 2 and a rear head seat 3. The front head seat 2 is provided with two front head bearing seats 21 and 22, and the two front head bearing seats 21 and 22 are connected by a first connecting block 23. The rear head seat 3 is provided with two rear head bearing seats 31 and 32, and the two rear head bearing seats 31 and 32 are connected by a second connecting block 33. By adopting this connection method, the two bearing seats on the head seat are connected as a whole, so that when adjusting the levelness, only one bearing seat needs to be adjusted to complete the levelness adjustment of the two knife shafts, which can effectively improve the installation speed of the knife shaft.

The front machine head bearing seats 21 and 22 are arranged on a mounting plate 24, and the mounting plate 24 is slidably arranged on a support plate 25, so that the position adjustment of the front machine head bearing seats 21 and 22 can be achieved by simply adjusting the position of the mounting plate 24. A fastening bolt 29 can be provided on the mounting plate 24, and a long groove corresponding to the position of the fastening bolt 29 can be provided on the support plate. When the position is adjusted, the fastening bolt 29 is in a loose state, and the fastening bolt 29 can move in the long groove. When the adjustment is in place, the mounting plate 24 and the support plate 25 can be fixed by tightening the fastening bolt 29, so that the front machine head bearing seats 21 and 22 are fixed.
