Scraper Strip Eccentric Guide Track Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scraper devices for round balers face challenges in adjusting the spacing distance between the scraper strip and moving components, such as rollers, due to wear or changes in machine settings, making it complicated to maintain optimal function and prevent adhesions.
Innovation Solution
A scraper strip with a rotatable adjusting means, such as an eccentric guide track or adjusting disk, allows for linear displacement and adjustment of the scraper strip relative to the support, enabling easy and uniform spacing adjustment between the scraper strip and moving components like rollers or belts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screw fittings are used to fasten the scraper strip, then the scraper strip can be securely attached to the support, but the adjustment of spacing distance becomes complicated and time-consuming
Solution Approach 1:
The scraper strip is designed with movable fastening elements that can be easily displaced along the support structure, transforming the static fastening system into a dynamic one that allows quick adjustment of spacing distance without complicated mechanisms
Solution Approach 2:
Multiple identical fastening points are provided along the scraper strip and support, allowing the adjustment operation to be replicated at different locations, simplifying the adjustment process by providing standardized, interchangeable fastening positions
2Reliability
If the scraper strip is positioned close to the roller to effectively remove adhesions, then scraping performance is improved, but any wear or setting changes require frequent readjustment
Solution Approach 1:
The scraper strip is pre-positioned at multiple fixed spacing distances along the support structure, allowing operators to quickly select and switch between pre-determined optimal positions without performing complex adjustments, thus maintaining consistent scraping performance while minimizing adjustment time
Solution Approach 2:
The system provides discrete, pre-defined spacing distance parameters that can be quickly switched between, allowing the scraper strip to maintain optimal distance from the roller surface for effective adhesion removal while enabling rapid parameter changes when wear or conditions require adjustment

AI summary
A scraper strip for a scraper device including at least one adjusting disk positioned in a recess of the scraper strip and rotatably attached to a scraper strip support, the adjusting disk comprising an eccentric guide track, which extends in a spiral shape or at least approximately as a circle involute, from a region at least close to a center point of the at least one adjusting disk in the direction of an edge region of the adjusting disk, and so as to linearly displace the scraper strip with respect to the scraper strip support of the scraper device when the adjusting disk is rotated. A fastener is accommodated by a groove extending substantially in a displacement direction of the scraper strip such that the scraper strip is displaced with respect to the fastener.
