Fixing device for the dust bag of a dust collector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collector fixing devices require significant manpower and coordination between two persons for assembly, making the process inconvenient and time-consuming due to the use of a thin, flexible cingule for securing the dust bag.
Innovation Solution
A fixing device with two tightening units and an annular frame that allows for quick assembly and disassembly by a single person, featuring adjustable components that securely fix the dust bag using a ring-shaped annular frame and a wind guide box with a gap mechanism for easy insertion and clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cingule is used to fix the dust bag, then the dust bag can be secured on the dust collector, but the assembly requires two persons and much time
Solution Approach 1:
The cingule is divided into multiple segments with tightening units distributed around the wind guide box. Each tightening unit can be operated independently, allowing one person to secure the dust bag efficiently while maintaining reliable fixation through distributed pressure points.
Solution Approach 2:
The tightening units feature adjustable members that can be dynamically positioned to different tightness levels. This dynamic adjustment capability allows the system to adapt to different dust bag sizes and installation requirements, maintaining reliable fixation while enabling quick assembly by a single operator.
2Adaptability or versatility
If a long thin cingule is used, then the dust bag can be wrapped around the flange, but the assembly process becomes complex and requires coordination between two persons
Solution Approach 1:
The continuous cingule is segmented into multiple fixed sections with individual tightening units. This segmentation transforms the complex task of wrapping and securing a long belt into simpler, independent tightening operations that can be performed easily by one person while maintaining adaptability to different dust bag configurations.
Solution Approach 2:
The tightening units act as intermediary mechanisms between the dust bag and the wind guide box. Instead of directly manipulating the entire cingule, the operator interacts with the simplified tightening units, which mediate the fixation process and eliminate the need for complex coordination between multiple persons.
3Strength
If the cingule is wound around the flange like a girdle, then the dust bag is tightly fixed, but the assembly requires precise coordination and much time
Solution Approach 1:
The fixation system is divided into multiple segmented tightening units distributed around the wind guide box. Each unit provides localized strong fixation, eliminating the need to wrap and secure an entire long cingule. This segmentation maintains overall fixing strength while reducing assembly time and eliminating the need for precise coordination between multiple operators.
Solution Approach 2:
The tightening units are pre-positioned around the wind guide box in optimal locations. This preliminary arrangement of fixation points allows the dust bag to be quickly secured without the time-consuming process of measuring, wrapping, and adjusting a continuous cingule, while still achieving strong fixation through the pre-optimized distribution of tightening units.

AI summary
A fixing device for the dust bag of a dust collector includes a dust collector provided with a wind guide box having its lower side formed with a stuff falling opening, which extends downward to form a ring body. The wind guide box has its outer circumference provided with two tightening units, and an annular frame is connected between the two tightening units and positioned beneath the ring body. The two tightening units can adjust the annular frame to be at a first position or at a second position able to quickly fix or disassemble the dust bag of a dust collector.
