Development of a Bamboo Toothbrush Handle Machine with a Human–Machine Interactive Interface for Optimizing Process Conditions

Non-renewable materials like plastics are widely applied on toothbrush handles and bristles. Polypropylene (PP) or polyethylene (PE) is often used to fabricate the handle, while nylon (PA) form bristle. These sourced from non-renewable fossil fuels. The primary greenhouse gases—nitrous oxide (N2O) carbon dioxide (CO2)—in Earth’s atmosphere released during production of these plastics. Bamboo can generate 30% more oxygen than most plants trees, which absorbs twice as much trees. A comparison cradle-to-grave material requirements between bamboo plastic toothbrushes reveals that entail hidden environmental costs. Nevertheless, be completely decomposed in environment, makes them eco-friendly sustainable green products. This research aims develop a handle machine with human–machine interactive interface management for optimizing process conditions. designed double-group stably mass-produce high-quality under optimal Although material, shaping difficult due an extremely anisotropic property structures. An improper condition will induce rough scorched surface, may further cause tearing crack. milling usually by profiler, uses various molds change shapes sizes handles. cannot probe accurate cutting force operations, paths, parameters. proposed equipment design includes two storage racks raw materials, feeding devices, exchange clamping dual-spindle system required whole propelled computer numerical control (CNC) SYNTEC controller, dimensions. controller integrated LabVIEW via Modbus RTU communication protocol. manufacturing methods, rates verified surveillance detect instant currents both spindles trial-and-error method mass production. maximum output reach four per minute 1600 day.
