[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] Example 1

[0021] See also Figure 1-2 : A battery electrode cutting spacing adjustment mechanism comprises an upper blade assembly 1, a lower blade assembly 2 and a motor assembly 3, wherein the upper blade assembly 1 is threadedly mounted with an upper blade 101, the lower blade assembly 2 is fixedly mounted with a lower blade 201, and the motor assembly 3 is drivingly connected to the upper blade 101 to drive the upper blade 101 to rotate so as to control and adjust the lateral distance.

[0022] In this embodiment, the motor assembly can drive the upper blade threadedly mounted on the upper blade assembly to rotate precisely, thereby driving and controlling the lateral movement of the upper blade, thereby achieving adjustable spacing between the upper blade and the lower blade, thereby solving the burr and material falling problems caused by inappropriate spacing between the upper and lower blades.

[0023] In a specific example, the upper blade assembly 1 includes an upper blade shaft 102, a screw sleeve 103 and a blade rotating sleeve 104.

[0024] When the blade sleeve is rotated, the blade sleeve can move left and right on the screw sleeve, thereby adjusting the gap between the upper blade and the lower blade.

[0025] It should be noted that the upper cutter shaft of the present embodiment is connected to the driving mechanism of the battery electrode sheet cutting system, and the upper cutter shaft is driven to rotate by the driving mechanism.

[0026] In a specific example, a locking screw 105 is further included, and the locking screw 105 is installed on the blade rotating sleeve 104 .
