Blade Holder Locking Mechanism for Precision Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing blade holders for longitudinal cutting machines, the adjusting slide can inadvertently move out of its starting position during the cutting process, interfering with the cutting process and potentially damaging the lower blade.
Innovation Solution
A mechanism is introduced that locks the blade holder from actuation when the adjusting slide is moved out of its starting position, ensuring it can only be used for cutting when manually returned to its starting position, preventing automatic actuation until alignment is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the adjusting slide is moved out of its starting position for positioning the blade head, then the alignment precision with the lower blade is improved, but the risk of damaging the lower blade during automatic actuation increases
Solution Approach 1:
The patent applies preliminary anti-action by introducing a locking mechanism that prevents automatic actuation of the blade holder when the adjusting slide is in the positioning position. The control unit detects the position of the adjusting slide and blocks the actuator from operating, thereby preemptively preventing potential damage to the lower blade before it can occur.
Solution Approach 2:
The control unit serves as an intermediary between the actuator and the blade holder mechanism. It monitors the position of the adjusting slide and mediates the actuation process by enabling or disabling automatic actuation based on whether the adjusting slide is in the starting position or positioning position, thus preventing harmful interactions.
2Reliability
If a locking mechanism is introduced to prevent actuation when the adjusting slide is positioned, then the safety against blade damage is improved, but the device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it monitors the position of the adjusting slide, determines whether automatic actuation should be permitted, and controls the actuator accordingly. By making the control unit multi-functional, the patent avoids adding separate dedicated locking mechanisms, thereby minimizing the increase in device complexity while still achieving improved reliability.
Solution Approach 2:
The locking function is merged with the existing control unit rather than being implemented as a separate mechanical locking device. The control unit combines the functions of position detection, decision-making, and actuator control into a single integrated system, reducing overall device complexity while maintaining safety.

AI summary
A blade holder (1) for a longitudinal cutting machine includes a rotatably mounted blade head (3) for holding a circular blade (4) and at least one locking device (2). At least one actuator actuates an element of the blade holder (1), and a moveably mounted adjusting slide (5) positions the blade head (3) on the longitudinal cutting machine. The adjusting slide (5) for positioning of the blade head (3) is moveable from a starting position to a positioning point. With the blade holder, materials can be cut perfectly with high precision. In particular, materials such as tissue, non-woven materials, paper, OLED film, displays, battery film, lithium batteries, aluminum, copper film, anodes, and cathodes can be cut.
