Ultrasonic Welding Machine

Goal - To create an ultrasonic welder for synthetic fabrics. "Ultrasonic Sewing"...

This is an unproven idea / work in progress... 4-5-2020

Initial Seed Idea - A stationary ultrasonic tool horn presses against a geared and knurled imprinting wheel; The geared wheel serves as the feed dog mechanism to feed the material through the machine and presses the material between the ultrasonic tool head.

An assumption is made that the ultrasonic vibration will assist the stationary side to slide across the material. If this does not work, then a circular ultrasonic horn will be explored.

Foot operated feed mechanism with adjustable stepper motor speed. Ramp up/down and speed settings can be programmed into the stepper controller.

Can also be used in stationary mode / spot welding mode.

Ultrasonic welder horn is mounted to a linear rail, and gravity ,weights ,or a spring can be used to set the normal force.

The geared imprinting wheel has a M3 belt tooth. M3-310 or large
