Vacuum Forming Machine Static Removal and Dust Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum forming processes often result in dust accumulation on the surface of base members, which can ruin the appearance of the vacuum formed products, especially when decorative sheets with metal layers are used.
Innovation Solution
A vacuum forming machine equipped with static removers and dust collectors that create a static-free space and collect dust effectively, preventing dust accumulation by using non-blowing static removers and positioning dust collectors to intercept exhaust air, thereby electrifying and adsorbing dust particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a vacuum forming process is performed using a decorative sheet, then the decorative sheet can be attached onto the base member, but dust accumulates on the surface of the base member and ruins the appearance of the vacuum formed product
Solution Approach 1:
A dust collector is introduced as an intermediary component between the exhaust port and the chamber interior. The dust collector intercepts dust particles carried by exhaust air before they can settle on the base member surface, thereby preventing dust accumulation while maintaining the vacuum forming process
Solution Approach 2:
Instead of using mechanical blowing methods to remove dust, the invention uses electrostatic fields generated by the exhaust air flow through the dust collector to attract and remove dust particles. The exhaust air itself generates the electrostatic field needed for dust collection without requiring additional mechanical blowing systems
2Object-affected harmful factors
If static electricity is present on the base member surface, then dust is attracted to the surface, but blowing air to remove static electricity may disturb the vacuum forming process
Solution Approach 1:
The exhaust air serves as an intermediary medium that carries both the harmful dust particles and the electrostatic field generation function. By utilizing the existing exhaust air flow, the system generates electrostatic fields for dust collection without introducing additional air flow that would disturb the vacuum forming process
Solution Approach 2:
The exhaust air system performs dual functions: it removes dust from the chamber and simultaneously generates electrostatic fields for dust collection. The system uses its own exhaust air flow to create the electrostatic field needed for dust removal, eliminating the need for separate static removal systems
