Barcode Printer Pivotal Holding Member for Stable Paper Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barcode printers lack adjustability for paper height, leading to unstable paper feeding, tilting, and wobbling, which affects printing quality and makes troubleshooting difficult, especially when jams occur.
Innovation Solution
A barcode printer design featuring a frame with a paper receiving device, printing device, cutting device, and output device, including a pivotal holding member, paper delivering roller, and sensors to stabilize paper feeding, cutting, and output, with adjustable components to match paper length and detect low inventory levels, facilitating easy jam removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the paper receiving device uses a fixed structure, then the device complexity is low, but the paper feeding stability deteriorates due to tilting and wobbling
Solution Approach 1:
The paper receiving device employs a pivotal holding member that can rotate about a pivot axis, allowing the receiving space to dynamically adjust its inclination angle. This dynamic structure enables the device to adapt to different paper lengths and maintain stable paper feeding by optimizing the angle at which paper enters the printing device, thereby preventing tilting and wobbling without requiring an overly complex mechanism.
2Adaptability or versatility
If the paper receiving device is not adjustable, then the device complexity is low, but the adaptability deteriorates when paper length varies
Solution Approach 1:
The pivotal holding member provides a dynamic adjustment mechanism where the receiving space can rotate to different inclination angles based on paper length. This allows the device to adapt to various paper dimensions by simply rotating the holding member to the appropriate angle, achieving high adaptability without complex adjustable structures.
Solution Approach 2:
The device changes the inclination angle parameter of the receiving space by rotating the pivotal holding member. This parameter change allows the same structure to accommodate different paper lengths effectively, as the angle adjustment optimizes paper feeding for each specific paper dimension without requiring multiple fixed configurations.
3Ease of operation
If the paper output device structure is fixed, then the manufacturing cost is low, but the ease of operation deteriorates during jam troubleshooting
Solution Approach 1:
The paper output device is segmented into distinct components including a paper output seat, a top cover that can be opened, and a paper output roller unit. This segmentation allows users to easily access the interior of the output device by opening the top cover and removing the roller unit, facilitating convenient jam troubleshooting and paper removal without requiring disassembly of the entire output device structure.

AI summary
A barcode printer includes a frame on which a paper receiving device, a printing device, a cutting device, and a paper output device are disposed. The paper receiving device receives a plurality of printing papers which is interconnected and folded in a zigzag manner. A front edge of the uppermost printing paper is inserted downward into a paper inlet passage of the printing device. A paper delivering motor moves the uppermost printing paper forward to pass through a gap between a printer and a paper delivering roller. A printer is activated to print a barcode on a lower face of the uppermost printing paper. The front edge of the uppermost printing paper is moved to pass through the cutter and the paper output roller unit. The paper delivering motor is then stopped, and a rear edge of the uppermost printing paper is cut under operation of a paper output motor.
