Self-Restoring Pressure Element for Cylindrical Body Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for receiving and stopping cylindrical bodies in the papermaking industry are inefficient in terms of energy consumption and receiving capability, with conventional pneumatic and hydraulic systems using excessive energy and steel stoppers being slow and prone to energy rebound.
Innovation Solution
The method employs tight, self-restoring pressure elements, such as hoses or bellows with self-restoring porous material, where the motion speed of cylindrical bodies is decelerated by adjusting the inflow and outflow of compressed air, allowing for controlled reception without continuous energy supply, using adjustable outlet flues and electromagnetic valves for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pneumatic or hydraulic cylinders are used for receiving cylindrical bodies, then the receiving capability is improved, but the energy consumption increases remarkably
Solution Approach 1:
The invention uses a dynamically adjustable pneumatic spring system where the stiffness and damping characteristics can be varied during operation. The pneumatic cylinder's pressure and flow characteristics are modulated to provide optimal receiving performance across different operating conditions, replacing the static high-energy pneumatic/hydraulic cylinder system.
Solution Approach 2:
The system changes physical parameters (pressure, flow rate, stiffness) of the pneumatic spring dynamically during the receiving process. By adjusting these parameters, the system achieves effective receiving capability while consuming significantly less energy than conventional systems that rely on high-pressure pneumatic or hydraulic cylinders.
2Use of energy by moving object
If a steel stopper is used for receiving cylindrical bodies, then the energy consumption is reduced, but the receiving properties deteriorate and the process takes a long time
Solution Approach 1:
The invention introduces a pneumatic spring as an intermediary between the cylindrical body and the steel stopper. This pneumatic element provides a compliant, energy-absorbing interface that improves receiving properties compared to direct steel-on-steel contact, while still maintaining low energy consumption through controlled air discharge.
Solution Approach 2:
The invention applies pneumatic principles by using a pneumatic spring (compressed air reservoir) to provide the receiving action. The controlled discharge of compressed air through regulated openings creates a damping effect that improves receiving performance without the high energy consumption of powered pneumatic cylinders.
3Force
If pneumatic bellows or hose are used to intensify receiving force, then the receiving force is increased without energy consumption, but the cylindrical body receives its energy back during return motion
Solution Approach 1:
The invention extracts and dissipates the rebound energy through controlled discharge openings in the pneumatic spring. By providing regulated pathways for air escape, the system removes the energy that would otherwise be returned to the cylindrical body during its return motion, preventing the harmful rebound effect while maintaining the force-intensification benefit.
4Reliability
If the receiving is performed by removing energy from a large cylinder, then the receiving takes place effectively, but the energy consumption is remarkable
Solution Approach 1:
The invention uses periodic action through the controlled discharge of compressed air in stages. The regulated openings allow air to escape in a controlled manner during the receiving process, creating a progressive energy dissipation effect that maintains receiving effectiveness while minimizing the total energy that must be supplied to and removed from the system.
