Adjustable Conveyor Belt Seal Assembly for Bounce and Wear Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor belt seals made of flexible materials like rubber tend to pucker and wear due to friction, especially when exposed to outdoor conditions, and they bounce at the curve where the sealing strip transitions from vertical to horizontal, leading to inefficiencies and product loss.
Innovation Solution
An adjustable belt seal assembly comprising a belt seal portion and a pressure plate, where the belt seal can be adjusted in height and pressure through slots and bolts, and the pressure plate applies additional pressure to the heel portion of the belt seal to reduce bounce and ensure a consistent seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible rubber sealing strip is used to seal against the conveyor belt, then the seal can accommodate belt movement and friction, but the sealing strip puckers and wears over time from frictional contact and outdoor conditions
Solution Approach 1:
The sealing strip is designed with dynamic adjustment capability through slots and bolts that allow the strip to be repositioned vertically. This enables the seal to adapt to belt wear and maintain optimal contact pressure over time, resolving the contradiction between flexibility and durability by making the flexible component adjustable rather than fixed
Solution Approach 2:
The invention changes the parameter of sealing strip position and pressure by providing adjustable mounting mechanisms. The sealing strip's vertical position can be modified to compensate for wear, and the pressure plate can adjust contact pressure, transforming a static flexible seal into a dynamically adjustable one that maintains reliability
2Area of stationary object
If the sealing strip is made slightly longer than the distance above the conveyor belt to increase contact surface area, then sealing contact is improved, but the sealing strip bounces back at the curve location where it transitions from vertical to horizontal
Solution Approach 1:
A pressure plate is introduced as an intermediary component between the sealing strip and the conveyor belt. This pressure plate applies downward force to suppress the natural bounce of the curved sealing strip while maintaining contact pressure, allowing the strip to retain its extended length for increased contact area without the instability of bouncing
Solution Approach 2:
The pressure plate acts as a counterweight mechanism, applying downward force to counteract the upward bounce tendency of the flexible sealing strip at its curve. This balances the forces on the sealing strip, enabling it to maintain stable contact with the conveyor belt surface
3Manufacturing precision
If the height of the sealing strip is adjusted to improve sealing, then sealing performance is enhanced, but the bounce at the curve of the strip remains an issue
Solution Approach 1:
The sealing system is segmented into separate functional components: the sealing strip for contact, the pressure plate for stabilizing and applying force, and the adjustable mounting mechanism. This segmentation allows the sealing strip to be optimized for sealing contact while the pressure plate independently handles the bounce stabilization function
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 assembly effectively reduces seal bounce and wear, maintaining a consistent seal and minimizing product loss by applying adjustable pressure to the heel portion, enhancing the conveyor belt's operational efficiency.
Implementation Method 1
the belt seal will naturally want to bounce back at the location where it curves from vertical to horizontal
