AI Technical Summary
The existing scrap removal molds have uneven boss heights, requiring temporary padding with foam or tape. This prevents the scrap from being completely and smoothly removed, making operation inconvenient and collection difficult.
The system employs a cylinder, air pipe, ejector pin, and collection trough. The roller is driven by a first servo motor and works in conjunction with a drive roller driven by a second servo motor. The product is synchronously transferred through the drag film. The cylinder provides compressed air, which is transmitted through the air pipe to the guide pipe inside the roller, pushing the piston to drive the ejector pin to extend and retract within the boss, thereby accurately ejecting waste material.
It enables smooth separation and centralized collection of waste materials, eliminating the tedious steps of manual cleaning, improving production efficiency and product quality, and reducing the cost of manual intervention and material waste.
