Cutting Machine Head with Controlled Cutter Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper cutting machines produce extra cutting lines due to uncontrollable rotation of the cutter head, leading to flawed cutting patterns.
Innovation Solution
A cutting machine head with multiple cutter head assemblies, each controlled by a machine head rotating mechanism for precise angle adjustment, ensuring the cutting line aligns perfectly with the defined path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cutter head is eccentrically mounted on the cutter seat and rotatable relative to the cutter seat, then the machine can complete cutting operations, but the cutter head rotates uncontrollably at the beginning of cutting, leaving extra cutting lines and compromising cutting pattern integrity
Solution Approach 1:
The patent applies preliminary action by introducing a positioning component that pre-positiones the cutter head at a predetermined angle before the cutting operation begins. This preliminary positioning ensures that the cutter head starts from a known, correct angular position, eliminating the uncontrollable rotation and extra cutting lines that occur with conventional eccentric mounting without pre-positioning mechanisms.
2Productivity
If the machine head is lowered to bring the cutter head into contact with the paper, then cutting can be performed, but the cutter head rotates to an appropriate angle during contact, generating force and creating extra cutting lines
Solution Approach 1:
The positioning component performs preliminary angular positioning of the cutter head before the machine head contacts the paper. This ensures that when the cutter head engages with the paper, it is already at the correct angle, preventing the unwanted rotation and extra cutting lines while maintaining efficient cutting speed.
Solution Approach 2:
The patent incorporates feedback mechanisms through the positioning component that monitors and adjusts the cutter head angle during operation. This feedback control ensures the cutter head maintains the predetermined angle throughout the cutting process, preventing deviations that would create extra cutting lines.
3Device complexity
If a single cutter head assembly is used, then the device complexity is low, but the cutting pattern integrity cannot be guaranteed due to uncontrollable rotation
Solution Approach 1:
The positioning component is integrated into each cutter head assembly to provide preliminary angular positioning. This addition of a positioning mechanism to each assembly ensures reliable cutting pattern integrity while maintaining reasonable device complexity through modular integration.

AI summary
A cutting machine head and a cutting machine are provided in the present invention. The cutting machine head includes a fixing plate, a cutter holder, a cutting component, a machine head lifting mechanism and a machine head rotating mechanism. The cutter holder is mounted on the fixing plate. The machine head lifting mechanism is connected to the cutter holder, and is used to drive the cutter holder to move up and down on the fixing plate. The cutting component includes at least two cutter head assemblies mounted on the cutter holder. The machine head rotating mechanism is connected to the cutter head assemblies for driving the cutter head assemblies to rotate. The rotating angle of each cutter head assembly of the cutting machine head can be controlled. The machine head rotating mechanism controls the cutter head assembly to rotate when the machine head is cutting, and the resulting cutting line has no flaws, which can ensure the integrity of the cutting pattern.
