Servo Press Block Mechanism for Stable Electric Strapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric strapping tools require manual operation of a hand-operated lever before and after packing, complicating the process and affecting stability, making them inconvenient to use.
Innovation Solution
A strapping tool with a press unit featuring a servo mechanism that lifts and lowers a press block using a button-activated servo, allowing seamless passage and pressing of a packing strap without changing the grip position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-operated lever is used to lift and lower the press block, then the strapping tool can be operated manually, but the operation becomes complicated and inconvenient
Solution Approach 1:
The patent replaces the manual hand-operated lever mechanism with an electric motor-driven system. The motor automatically lifts and lowers the press block through electrical control, eliminating the need for manual lever operation and simplifying the user interface while reducing operational complexity
Solution Approach 2:
The strapping tool performs the pressing operation automatically through the motor-driven mechanism. Once the strap is positioned, the system self-activates to press the strap against the cargo without requiring continuous manual intervention, making the tool serve itself during the critical pressing phase
2Reliability
If a hand-operated lever is used for pressing, then the tool can function, but the strapping operation smoothness and stability are compromised
Solution Approach 1:
The patent substitutes the manual lever system with an electric motor control system that provides more consistent and stable pressing force. The motor-driven mechanism eliminates the variability and instability associated with manual lever operation, ensuring reliable and smooth strapping performance
3Productivity
If the press block is manually operated, then the tool structure can be simple, but the packaging efficiency is reduced
Solution Approach 1:
The patent introduces an electric motor to automate the press block operation, significantly increasing packaging efficiency. The motor-driven system can rapidly lift and press the block multiple times per minute, far exceeding manual operation speeds, while the added complexity is justified by the substantial productivity gain
Solution Approach 2:
The motor-driven system is pre-configured to automatically perform the pressing action at the optimal moment in the strapping process. The mechanism is designed to initiate pressing as soon as the strap is in position, eliminating delays associated with manual reaction time and maximizing packaging throughput
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
Enhances packaging efficiency and stability by simplifying the strapping operation through automated lifting and pressing of the press block, improving user convenience and operational quality.
Implementation Method 1
The servo has an output shaft. The output shaft is connected to a connecting shaft. The connecting shaft is connected to one side of the axle. The output shaft, the connecting shaft and the axle are rotated simultaneously.
Implementation Method 2
Another side of the axle is integrally formed with an eccentric shaft. The eccentric shaft extends outward. The eccentric shaft is fitted with a shaft seat. A press block is pivotally connected to the shaft seat.
