Baling Press Friction Welding Cooling Cycle

Solution Overview

Problem

Existing balers for agricultural crops face challenges in achieving high-performance and reliability due to time-consuming material connections and increased expenditure in bonding processes, particularly with band-shaped binding materials.

Innovation Solution

The baler incorporates an air cooling device that accelerates the curing of material connections by directing air flows onto the bonded areas, combined with a welding device that uses friction welding with a compressed air motor and a control system to optimize the binding cycle, ensuring quick and reliable material connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If friction welding is used to connect binding material ends, then material connection strength is improved, but binding cycle time increases

Engineering Contradiction:
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The patent changes the temperature parameter of the binding cycle by introducing active cooling. A cooling device with nozzles directs cooled air onto the material connection area, rapidly reducing the temperature and curing time of the welded binding material ends. This allows the friction welding process to maintain its high connection strength while significantly reducing the overall binding cycle time by accelerating the cooling and curing phases.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If welding device operates continuously, then productivity is improved, but energy consumption increases

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by controlling the welding device to operate in cycles rather than continuously. The control device activates the welding device only when binding material ends require connection, and simultaneously controls the cooling device to operate periodically during and after welding. This periodic operation maintains high productivity by keeping the system ready for rapid welding when needed, while reducing overall energy consumption by allowing the system to be in a lower energy state during non-welding intervals.

Inventive Principle:
Principle #19Periodic action
