This application provides an electrode plate slitting method and apparatus, an electronic device, and a storage medium. The method includes: obtaining a length of an electrode plate to be cut; and when it is determined that a slitting parameter meeting a preset condition exists based on the length of the electrode plate, cutting the electrode plate to be cut based on the slitting parameter to obtain the electrode plate after cutting. The preset condition includes: the slitting parameter is able to be used for cutting the electrode plate to be cut and a length of each electrode plate roll obtained after cutting is within a preset range. This decreases the probability of obtaining an electrode plate roll with an inappropriate length at the end of the cutting, reducing the waste in the electrode plate.

A self-propelled cutter has a gear assembly to provide both downward and forward force on a material to be cut. A gear assembly includes a drive input gear that engages with a transfer gear and propulsion gear engaged with the transfer gear by a lever arm. The drive gear and transfer gear are coupled and fixed to the cutter body but the propulsion gear rotates about the transfer gear via the lever arm. This gear assembly enables the propulsion gear to move as required to provide both downward and forward force on a material to be cut, such as a cast. A self-propelled cutter may have a drive input that is coupled with a drive input device, such as a crank or an electric motor. A cutter may have a first gear assembly on a first side of the cutter body and a second gear assembly on a second side.

The present invention relates to a printer having the same cover opening/closing direction as the paper cutting direction, and includes: a housing in which a receiving space is formed, on an upper part of which a discharging port through which paper is discharged is formed, and which includes a cover that is openable/closable frontward; a cutting unit that is provided in the receiving space and cuts the paper discharged through the discharging port in the opening/closing direction of the cover; and a discharging unit for discharging the paper from the housing.

Embodiments of the present application disclose an integrated paper and adhesive tape cutting device, including a housing, where the housing includes a paper cutting housing and a paper separating housing; a component for pulling out paper from a paper roll inside a paper separating component for cutting is arranged below the paper cutting housing; and a cutting device is arranged on an outer wall of the housing to cut an adhesive tape.

A method for splitting a semi-finished product includes placement of the semi-finished product on a splitting template, and the splitting template includes at least one elevation. The method includes fixation of the semi-finished product on the splitting template, in which an area of the semi-finished product is arranged on the elevation. The method includes splitting of the semi-finished product, in which material is removed from the semi-finished product during splitting. The material removal in the area that is arranged on the elevation is greater than in an area that is not arranged on the elevation.
