Core Mechanism
• Rotary Input (Motor Shaft):
A small DC motor or servo provides continuous rotational motion.
• Conversion System:
◦ Crank–Slider or Cam Mechanism: The rotating shaft drives a crank or cam that pushes/pulls a connecting rod.
◦ Linkages: These rods are attached to the wing base, converting rotation into oscillation.
◦ Elastic Elements (Springs/Bands): Often used to store and release energy, ensuring smooth wing return strokes.

Fully automatic sachet cutting and opening machine, compact tabletop industrial design, realistic mechanical structure.

Sachets are fed into dual rubber rollers that grip and push them forward. The rollers position the sachet so the top edge slightly protrudes into the cutting area.

A rotary circular blade partially cuts the top edge without fully separating it. After cutting, a mechanical opening system (dual arms or wedge) pulls the cut edges apart to open the sachet.

The rollers continue pushing the sachet downward through an angled guide path, allowing contents to fall by gravity into a cup below. Empty sachet exits through lower channel.

Include detailed components: rollers, shafts, bearings, gears, motor mounts, blade holder with guard, guide rails, opening arms, خروج funnel.

Style: realistic mechanical engineering, functional prototype, isometric view, clean industrial design, no abstract or sci-fi.
