Printer Cutting Apparatus Scraping Adhesive from Movable Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting apparatuses for printers with adhesive layers require costly tapered through-holes, leading to increased manufacturing costs and adhesive accumulation on blades during repeated cutting operations.
Innovation Solution
A cutting apparatus with a movable blade and a scraping-off device positioned to contact and remove adhesive from the blade, eliminating the need for tapered through-holes and reducing adhesive accumulation without increasing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If multiple tapered through-holes are disposed in the movable blade and fixed blade to remove adhesive, then adhesive removal is improved, but manufacturing cost increases
Solution Approach 1:
The harmful function of adhesive removal is extracted from the blade structure itself and assigned to a separate scraping-off device. This allows the blade to be simple and easy to manufacture while the dedicated scraping device handles adhesive removal, resolving the contradiction between effective adhesive removal and manufacturing cost.
Solution Approach 2:
A scraping-off device is introduced as an intermediary element between the movable blade and the adhesive layer. This mediator performs the adhesive removal function without requiring complex modifications to the blade structure, thereby maintaining manufacturing simplicity while achieving effective adhesive removal.
2Object-generated harmful factors
If multiple tapered through-holes are disposed in the movable blade and fixed blade, then adhesive removal is improved, but device complexity increases
Solution Approach 1:
The adhesive removal function is extracted from the blade structure and implemented by a separate scraping-off device. This separation simplifies the blade structure to a basic cutting edge while the dedicated scraping device handles adhesive removal, reducing overall device complexity.
Solution Approach 2:
The cutting apparatus is segmented into distinct functional components: the blade assembly for cutting and the scraping-off device for adhesive removal. This functional segmentation allows each component to be optimized independently, with the blade remaining simple and the scraping device handling the complex adhesive removal task.
3Ease of manufacture
If a scraping-off device is disposed separately from the movable blade and fixed blade, then manufacturing cost is reduced, but adhesive removal effectiveness may worsen
Solution Approach 1:
The scraping-off device acts as an intermediary that effectively removes adhesive through direct contact with the movable blade surface. By positioning this dedicated scraping element in proximity to the blade, effective adhesive removal is achieved without the need for complex blade structures with multiple through-holes.
Solution Approach 2:
The scraping-off device is designed to automatically remove adhesive during the cutting operation itself, utilizing the relative motion between the movable blade and the scraping device. This self-service mechanism ensures continuous adhesive removal without additional complex systems, maintaining effectiveness while reducing manufacturing cost.

AI summary
The disclosure discloses a cutting apparatus including a feeder, a fixed blade, a movable blade, and at least one scraping-off device. The movable blade is configured to slide in a sliding direction crossing a transport direction against the fixed blade and is configured to move along the sliding direction from a standby position on one side to a cutting position on the other side and to cut the print-receiving medium fed by the feeder. The at least one scraping-off device is disposed in proximity to the movable blade and is configured to come into contact from the other side with an adhesive that has adhered to the movable blade and scrape off the adhesive when the movable blade moves from the standby position on the one side to the cutting position on the other side.
