Problem
Existing fully automatic presses face limitations such as low powder weighing efficiency, unsatisfying release agent spraying effect, and frequent collisions due to errors in the powder feeding device, which affect normal operation and reduce the service life of the equipment.
Innovation Solution
The design incorporates multiple feed pipes and hoppers connected to powder weighing mechanisms, a discharge pipe with a vibration motor, and adjustable release agent sprayers, along with a powder blocking mechanism and shock absorption features to enhance efficiency and reduce collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single feed hopper and powder weighing mechanism are used, then the device complexity is low, but the powder weighing efficiency is low
Solution Approach 1:
The patent divides the single feed hopper into multiple feed hoppers (first feed hopper, second feed hopper, etc.) and corresponds them with multiple powder weighing mechanisms. This segmentation allows parallel operation of multiple weighing mechanisms, thereby improving powder weighing efficiency while maintaining manageable device complexity through modular design
Solution Approach 2:
The patent introduces a vertical dimension by arranging multiple feed hoppers at different positions and using a discharge pipe that extends vertically to distribute powder to multiple weighing mechanisms. This spatial arrangement enables simultaneous operation of multiple weighing mechanisms without increasing the horizontal footprint significantly
2Adaptability or versatility
If the release agent spraying mechanism is fixed to the powder conveying device, then the device complexity is low, but the release agent spraying effect is limited and cannot be adjusted
Solution Approach 1:
The patent makes the release agent spraying mechanism dynamic by allowing it to move independently from the powder conveying device. The spraying mechanism can be positioned at different locations and adjusted to spray onto different surfaces, enabling adaptation to various spraying requirements while maintaining reasonable device complexity through independent positioning
3Reliability
If the powder feeding device uses vibration mechanism for discharge, then the powder can be discharged, but frequent collisions occur due to processing errors, affecting service life
Solution Approach 1:
The patent introduces a cushioning mechanism that provides beforehand cushioning for the powder feeding device. This cushioning mechanism absorbs shocks and reduces the impact of collisions before they can cause damage, thereby extending the service life of the powder feeding device while maintaining normal powder discharging functionality
