Portable paper trim removal system with trim rewinder and dust vacuum

摘要

A system for collecting paper trim and dust automates and simplifies the removal and disposal of trim. The system includes a funnel receiving the paper trim from an automatic trimmer, a drum and rewinder for winding the paper trim into a bale, and a dust trap for sucking dust from the drum and funnel into a dust bin. As the trim is baled, the rewinder drags the paper bale against the side of the drum. This drag compacts the bale and increases the load on the rewinder. As the drag load on the rewinder increases, the rewinder is moved radially towards the center of the drum to increase the distance between the rewinder and the drum wall. A current sensing circuit triggers the radial movement of the rewinder when the current load on the rewinder motor exceeds a threshold limit. This radial movement reduces the drag on the rewinder. When the rewinder reaches the center of the drum and the trim bale fills the drum, the rewinder is stopped and the trim bale removed.
