Projeto de melhoria em uma máquina de corte e solda de plástico

Abstract

This paper presents the development of a prototype model featuring a cleaning roller and waste collection tray for the G4 1100 plastic cutting and welding machine, based on a concept from the company Plaswill. The primary objective is to eliminate the need for daily manual cleaning of the lower pull roller, which accumulates plastic film residue, is difficult to access, consumes significant time, and exposes operators to ergonomic and safety risks. The methodology adopted involved measuring available space, creating 2D drawings, analyzing materials, estimating costs, procuring components (Nema 17 stepper motor, TB6600 driver, and pneumatic actuator), and performing assembly and testing. The proposed system allows the cleaning roller to contact the pull roller during rotation—using a damp Velcro strip treated with degreaser—collecting residue in the tray and automatically returning to the initial position. Aligned with NR-12 safety standards, the prototype demonstrates a viable solution aimed at improving production efficiency, reducing manual interventions, and enhancing safety during the operation of the actual machine.
