Cutter Disc Cover Cooling with Adjustable Nozzle and Liquid Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc cutters with protective covers and cooling systems suffer from inefficient cooling due to a fixed cooling liquid supply tube and rapid spraying of liquid against the curved perimeter wall, leading to insufficient cooling and waste of cooling capacity, especially at varying flow rates.
Innovation Solution
A protective cover with a semi-cylindrical cavity and adjustable nozzle positions for optimal liquid distribution, along with internal flaps to redirect and reuse sprayed liquid, ensuring effective cooling by varying nozzle positions based on flow rates and utilizing the sprayed liquid before it leaves the cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed position tube with nozzle is used for cooling the disc, then the device structure is simple, but the cooling effectiveness becomes insufficient when flow rate varies
Solution Approach 1:
The patent applies the dynamics principle by making the nozzle position adjustable rather than fixed. The nozzle can be positioned in multiple locations (upper, lateral, lower) to adapt to varying flow rates and operational conditions, thereby maintaining effective cooling across different scenarios while managing structural complexity through a controlled adjustment mechanism.
Solution Approach 2:
The patent changes the positional parameter of the nozzle to optimize cooling effectiveness. By allowing the nozzle to be positioned at different locations relative to the disc, the system can adjust the cooling liquid delivery parameters to match varying flow rates and cutting conditions, resolving the contradiction between structural simplicity and cooling reliability.
2Device complexity
If the cooling liquid is sprayed against the curved perimeter wall during disc rotation, then the cover structure is simple, but the cooling liquid is wasted without effectively cooling the disc
Solution Approach 1:
The patent converts the harmful centrifugal spraying effect into a beneficial recirculation system. Instead of allowing cooling liquid to be wasted by centrifugal force against the perimeter wall, the system uses this same centrifugal action to redirect the liquid through flaps and channels back onto the disc, transforming the waste problem into a cooling enhancement mechanism.
Solution Approach 2:
The patent implements a recovery mechanism for the cooling liquid. The flaps and channels capture the centrifugally sprayed liquid that would otherwise be lost, and redirect it back onto the disc surface. This recovery system reduces cooling capacity waste while maintaining the relative simplicity of the cover structure.
3Reliability
If the nozzle is positioned to spray liquid horizontally at high flow rate, then cooling effectiveness is improved, but liquid waste increases against the perimeter wall
Solution Approach 1:
The patent converts the harmful centrifugal spraying effect into a beneficial recirculation system. Instead of allowing cooling liquid to be wasted by centrifugal force against the perimeter wall, the system uses this same centrifugal action to redirect the liquid through flaps and channels back onto the disc, transforming the waste problem into a cooling enhancement mechanism.
Solution Approach 2:
The patent implements a recovery mechanism for the cooling liquid. The flaps and channels capture the centrifugally sprayed liquid that would otherwise be lost, and redirect it back onto the disc surface. This recovery system reduces cooling capacity waste while maintaining the relative simplicity of the cover structure.
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
Optimizes disc cooling by allowing nozzle position adjustments for better liquid distribution at low and high flow rates, and reuses sprayed liquid to enhance cooling efficiency, reducing waste and improving cooling capacity.
Implementation Method 1
a nozzle (31) for dispensing a cooling liquid on the disc
Implementation Method 2
pours said cooling liquid on an area of the lateral surface of the disc close to its periphery
Implementation Method 3
the cooling liquid that comes into contact with the disc is rapidly sprayed against a curved perimeter wall of the cover, due to the centrifugal force created as the cutting disc rotates

AI summary
Protective cover with cooling for cutter discs; which comprises a generally semi-cylindrical cavity (15) that covers a portion of the cutting disc (2) at the top and that is delimited by two lateral walls (11, 12) and a curved perimeter wall (13). Said cavity (15) internally comprises, in its periphery, fastening means (16, 17) for a tube (3) and a cooling liquid supply nozzle (31) for the disc (2) in at least one upper position (P1) in which the nozzle (31) pours the liquid on the upper end of the disc (2), and one lower position (P5) in which the nozzle (31) sprays the liquid directly against the edge of the disc (2).
