Solution Overview
Problem
Existing banknote binding machines have complex and costly clamping mechanisms that require high actuating device requirements and additional components for stable and quick clamping, leading to increased economic costs and structural complexity.
Innovation Solution
A binding medium clamping mechanism featuring a rotatable clamping element, a driving element, a one-way transmission element, and a clamping head opening element, which allows for simplified and compact design by using a worm and worm wheel transmission and elastic elements to maintain the clamping position without additional actuating devices, enabling efficient clamping and opening of the mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional clamping mechanism is used with additional actuating devices to open the clamping element, then the clamping can be opened quickly and stably, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent removes the additional actuating device from the system. Instead of using a separate actuator to open the clamping element, the design extracts this function and integrates it into the driving element's rotation path, where the driving element directly opens the clamping element through interference at a specific position.
Solution Approach 2:
The patent merges the opening function into the driving element itself. The driving element serves dual purposes: driving the clamping element during normal operation and opening it when interference occurs, combining two functions into one component.
2Reliability
If additional actuating devices are added to ensure stable clamping position, then the clamping reliability improves, but the manufacturing cost increases
Solution Approach 1:
The patent eliminates the need for additional actuating devices, directly reducing component count and manufacturing cost while maintaining clamping position stability through the one-way transmission element and gravitational return mechanism.
Solution Approach 2:
The clamping head opening element uses its own gravity to return to the original position after being pushed away by the clamping element, eliminating the need for additional actuators or energy-consuming mechanisms to reset the system.
3Ease of manufacture
If the clamping mechanism is simplified by removing additional actuating devices, then manufacturing cost decreases, but the requirement on the actuating device increases
Solution Approach 1:
The driving element is designed to perform multiple functions: driving the clamping element during normal operation, opening the clamping element through interference, and working with the one-way transmission element to maintain position stability. This multi-functionality reduces the need for specialized high-performance actuators.
Solution Approach 2:
The one-way transmission element acts as an intermediary between the driving element and the clamping element, transmitting driving force in one direction while preventing reverse force transmission, thereby protecting the driving element from excessive load requirements.
4Device complexity
If the clamping head opening element is designed to rotate and move out of the moving track, then the structure becomes more compact, but the precision of positioning requirements increases
Solution Approach 1:
The clamping head opening element is designed to rotate freely under gravity to a stable equilibrium position where it naturally moves out of the clamping element's track. This gravitational equipotential approach simplifies positioning requirements compared to active control systems.
Solution Approach 2:
The limiting portion is pre-positioned to restrict the clamping head opening element's rotation in the second direction, preventing excessive movement and ensuring the element returns to the correct position after opening, thereby maintaining positioning accuracy without complex control.

Function Achieved in This Case
The solution results in a simplified, compact, and cost-effective banknote binding machine structure that reduces manufacturing costs while ensuring stable clamping and efficient operation, allowing for precise control of the clamping mechanism without additional actuating devices.
Implementation Method 1
The clamping head opening element is configured to return to its original position due to its own gravity in the case that the clamping element continues to push the clamping head opening element and is disengaged from the clamping head opening element.
Implementation Method 2
The one-way transmission element is a transmission structure having a worm and a worm wheel, and the driving element, the worm, the worm wheel and the clamping element are connected in the listed sequence.

AI summary
Disclosed are a binding medium clamping mechanism and a banknote binding machine containing the mechanism. The binding medium clamping mechanism comprises: a clamping element (1), a driving element (2), a one-way transmission element, and a clamping head opening element (4), wherein when the clamping element (1) rotates to the position of a binding medium to be clamped in a first rotation direction, the clamping head opening element (4) interferes with the clamping element (1) in positions and opens the clamping element (1), and when the clamping element (1) rotates in a second rotation direction which is opposite to the first rotation direction, the clamping head opening element (4) is pushed, so that the clamping head opening element (4) rotates to the outside of the motion track of the clamping element (1) in the first rotation direction. The clamping element (1) can move along the predetermined track via the drive of the driving element (2) and be locked when the drive is stopped. Meanwhile, the clamping head opening element (4) can interfere with the clamping element (1) when the clamping element (1) is required to be opened, and will not hinder the rotation of the clamping element (1) at other times. The entire structure is simple and compact, and the manufacturing cost is low.
