Problem
Conventional crushers for waste tires face difficulties in maintenance, repair, and controlling the width of tire strips, leading to high treatment costs and secondary pollution, with existing solutions being cumbersome and inefficient.
Innovation Solution
A crushing device with a roll shaft and adjustable crushing components, including cutting and grinding tools, radial supporting blocks, and axial interval adjusting blocks, integrated with a multi-functional crusher that allows for flexible operation and automatic recovery mechanisms, reducing production costs and improving maintenance convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixedly installed tooth rollers are used for crushing waste tires, then the crushing function is achieved, but the width of tire strips cannot be controlled and maintenance is difficult
Solution Approach 1:
The crushing device is divided into modular components including detachable tool assemblies that can be independently replaced. The toothed rollers are segmented into multiple tool units that can be individually adjusted or replaced without dismantling the entire crusher, enabling both strip width control and ease of maintenance.
Solution Approach 2:
The device transitions from fixed installation to adjustable and detachable configuration. The tool assemblies can be dynamically repositioned along the roller axis to control strip width, and can be quickly detached for maintenance or replacement, providing operational flexibility while simplifying maintenance procedures.
2Ease of repair
If conventional crushing devices are used, then crushing function is provided, but maintenance and repair are difficult leading to high treatment costs
Solution Approach 1:
The crushing device employs modular tool assemblies that can be independently accessed and replaced. Each tool assembly is a discrete unit that can be quickly detached and swapped without requiring disassembly of the entire crusher mechanism, significantly reducing maintenance time and improving ease of repair.
Solution Approach 2:
The tool assemblies are designed to be easily extracted from the roller structure. The detachable connection mechanism allows tools to be quickly removed and replaced at the maintenance location without moving heavy components or dismantling complex structures, enabling rapid tool replacement and reducing downtime.
3Productivity
If cutting and crushing operations are performed separately, then processing completeness is achieved, but treatment cost increases and secondary pollution occurs
Solution Approach 1:
The device integrates cutting tools and crushing tools into a single synchronized system operating on the same roller. The cutting section and crushing section work simultaneously in one continuous operation, eliminating the need for separate processing steps, reducing treatment cost, and minimizing secondary pollution from multiple handling operations.
Solution Approach 2:
The roller assembly serves multiple functions simultaneously - it performs both cutting and crushing operations in one pass. The universal tool assembly can be configured with different tool types (cutting teeth, crushing teeth, grinding elements) to handle multiple processing requirements in a single operation, improving productivity while reducing environmental impact.
