Center-Driven Cutter Mounting for Burr-Free Feeding Cuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cutting mechanisms in battery manufacturing suffer from uneven wear and inclining guides due to a force application point at one end of the guide rod frame, leading to gaps between the moving and stationary cutters, resulting in poor cutting quality and burr formation.
Innovation Solution
A feeding device with a cutting mechanism that applies force to a mounting piece via a driving assembly connected to its centerline, ensuring equal stress distribution and minimizing wear, using a guide mechanism with synchronized clamping to maintain precise cutting at a preset position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the driving assembly is connected to one end of the guide rod frame, then the structure is simple, but the stress is concentrated causing uneven wear and inclining guides
Solution Approach 1:
The patent transitions from connecting the driving assembly to one end of the guide rod frame (one-dimensional connection) to connecting it to the center of the mounting piece (central connection), effectively changing the spatial dimension of force application. This dimensional change in connection location distributes stress more evenly across the guide rod, preventing uneven wear and maintaining cutting precision without significantly increasing structural complexity
2Device complexity
If the force application point is at one end of the guide rod frame, then the driving assembly structure is simple, but the guide rod experiences severe wear and inclining guides
Solution Approach 1:
The patent applies preliminary action by designing the driving assembly to connect to the center of the mounting piece before operation begins. This preliminary structural arrangement ensures that force is distributed evenly from the start, preventing the guide rod from experiencing concentrated stress and severe wear during cutting operations, thereby improving reliability without complicating the driving assembly structure
3Device complexity
If the moving cutter and stationary cutter are connected via a guide rod with force at one end, then the mechanism is simple, but cutting gaps and burrs occur
Solution Approach 1:
The patent changes the connection dimension from end-based connection to center-based connection of the mounting piece. This dimensional shift in force application location ensures the guide rod remains straight and parallel during cutting, eliminating cutting gaps and burrs while maintaining the simplicity of the cutting mechanism structure

AI summary
The application relates to a cutting mechanism and a feeding device. The cutting mechanism comprises a cutter holder; a stationary cutter fixedly arranged on the cutter holder; a moving cutter assembly comprising a mounting piece and a moving cutter, the mounting piece being slidably arranged on the cutter holder in a first direction, the moving cutter being mounted on the mounting piece, and the mounting piece having a centerline parallel to the first direction; and a driving assembly comprising a first end and a second end, the first end being matched with a guide mechanism, and the second end being connected with a part of the mounting piece corresponding to the centerline; when the cutter holder drives parts located thereon to move in a second direction, the guide mechanism can drive the driving assembly to apply a driving force to the mounting piece in the first direction, so that the mounting piece drives the moving cutter to move close to the stationary cutter to cut a workpiece at a preset position, and the first direction intersects the second direction. According to the cutting mechanism and the feeding device, the problem that an end, avoid wear more seriously at the end of connection between the mounting piece and the cutter holder, which is close to a force application point, thus causing a cutting gap between the moving cutter and the stationary cutter is solved, and the cutting effect is good.
