Gardening Binding Machine Tape Gripping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines for gardening face issues with tape gripping, where thin tapes are easily torn and thick tapes are not adequately gripped, leading to detachment problems, especially at varying temperatures.
Innovation Solution
A binding machine with a tape gripping device that sandwiches the tape using a support portion and a gripping member, where the gripping member is rotatably attached and applies force in the pulling-out direction, engaging with the support portion to enhance grip strength and prevent detachment, and includes a tape guide with a slit for reliable tape gripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a claw is used to grip the tape by thrusting into it, then the gripping force is improved, but the tape is torn especially when thin tape is used or when the tape is cured at low temperature
Solution Approach 1:
The invention changes the gripping mechanism from a claw that thrusts into the tape to a pressing mechanism that applies force to the surface of the tape. The pressing member presses the tape against the support portion, changing the application method of gripping force from penetration to compression, thereby avoiding tape damage while maintaining adequate grip strength
Solution Approach 2:
The invention introduces a pressing member as an intermediary between the gripping mechanism and the tape. Instead of the claw directly thrusting into the tape, the pressing member mediates by pressing the tape against the support portion, distributing the force and preventing concentrated stress that causes tearing
2Force
If the claw is made to thrust more strongly into the tape to grip thick tape, then the gripping force on thick tape is improved, but the resistance when drawing out the tape increases and the tape is detached from the claw
Solution Approach 1:
The invention changes the gripping mechanism from thrusting to pressing, allowing adequate grip on thick tape without creating excessive resistance during tape draw-out. The pressing action maintains contact force while reducing the mechanical interlocking that causes high friction and detachment
Solution Approach 2:
The pressing member is configured to move between pressed and unpressed states, dynamically adjusting the gripping force. When the tape needs to be drawn out, the pressing member can be retracted or released, reducing resistance and preventing detachment while maintaining grip strength when needed
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
The solution allows for secure gripping of both thin and thick tapes without tearing, improving binding workability across different temperatures and reducing operational difficulties.
Implementation Method 1
a spring that urges the claw in the tape-gripping direction
Implementation Method 2
a wedge-shaped claw protruding toward the tape support plate is formed at a front end portion of the picking plate. When the tape gripping device grips the tape, the claw rotating by a cam mechanism and a spring is thrust into the tape

AI summary
A binding machine for gardening includes a main handle, a clincher arm and a tape gripping device. The main handle is configured to draw out a tape. The clincher arm is provided such that an end portion side of the clincher arm is configured to be close to and be away from a tape guide. The tape gripping device is attached to the clincher arm and is configured to grip the tape drawn out from the main handle. The tape gripping device includes a support portion and a gripping member. The support portion is provided on the clincher arm. The gripping member is provided so as to face the support portion. The tape gripping device is configured to sandwich and grip the tape by the support portion and the gripping member.
