Eccentric Slicer Blade Drive Above Chute
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular knife machines for cutting strand-shaped foods require a wide slot for the cutting blade, which compromises the machine's efficiency and hygiene due to the need for a large motor drive and intermediate wall, limiting the slot's narrowness and exposing critical components to contamination.
Innovation Solution
A cutting machine design with a shaft having two areas separated by a narrow slot, where the drive shaft is positioned above, and an intermediate wall is placed only in one area to protect components and allow the cutting knife to dip in from above, reducing the slot width and preventing contamination by forming a chamber that shields the motor drive and control elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the motor drive is located below the shaft floor, then the cutting blade can be driven from below, but the slot must be made wide which compromises hygiene and efficiency
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the motor drive above the shaft floor instead of below, and guiding the cutting blade downwards from above rather than upwards from below. This inversion allows the slot to be narrowed significantly while maintaining functional requirements.
Solution Approach 2:
The patent introduces an intermediate wall that extends vertically to separate the chute into upper and lower sections, creating a three-dimensional arrangement where the motor drive is positioned in a different vertical dimension above the chute, allowing the slot to be narrowed without compromising motor access.
2Reliability
If an intermediate wall is installed to protect components, then component protection is improved, but the device complexity increases
Solution Approach 1:
The intermediate wall serves multiple functions simultaneously: it protects the motor drive and control elements from food contamination, provides structural support for the chute separation, and creates a barrier that prevents food crumbs from entering the motor area. This multi-functionality reduces the need for additional protective components.
3Object-affected harmful factors
If the slot is made narrow, then hygiene is improved, but the motor drive space is reduced
Solution Approach 1:
The motor drive is positioned in the vertical dimension above the chute rather than horizontally adjacent to the slot, allowing the slot to be narrowed in the horizontal direction while the motor drive maintains adequate space in the vertical dimension for its operational requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for a narrower slot, improved hygiene by preventing food crumbs from entering the chamber, and easier maintenance access, while ensuring the cutting knife can be positioned close to the side wall for efficient cutting without contacting lubricants.

AI summary
The invention relates to a cutting machine for strand-shaped food products, comprising a cutting blade (12) for the strand-shaped food product, which is rotatably mounted on an eccentric arm (80). A chute for receiving the strand-shaped food product is provided, the chute having a first chute section and a second chute section, which are at least partially separated from each other by a slot. A drive shaft (14) for driving the eccentric arm (80) for the cutting blade (12) is arranged above the chute. According to the invention, an intermediate wall (74) is arranged behind the chute, extending parallel to the longitudinal direction of the chute. The intermediate wall (74) is present only in the area of the first chute section or only in the area of the second chute section. The cutting blade (12) is positioned next to the intermediate wall (74).
