11690419 · 2023-07-04 · ·

Disclosed is a preparation technology for an artificial eyelash with a naturally arc-shaped stem, which automatically presses and sticks artificial eyelash by providing a transmission mechanism for transmitting a double-sided adhesive tape, a limiting mechanism for storing the artificial eyelash, a pressing mechanism for pressing the double-sided adhesive tape to the limiting mechanism to stick the artificial eyelash and a control mechanism; automatically synthesizes the artificial eyelash by providing a feeding roller assembly, a distributing roller assembly, a synthesis extrusion roller assembly, a recycling roller assembly and a collecting roller; and automatically glues and shears the artificial eyelash by eyelash thread rollers, front limiting rollers, glue injection mechanisms, rear limiting rollers, drying mechanisms and finished product rollers symmetrically arranged on two sides of a multi-layer eyelash sticker. Through the processing technology, the labor cost is saved and the processing efficiency of the artificial eyelash is improved.

Impact forming of thermoplastic composites

Disclosed embodiments provide automated fiber placement techniques for fabrication of parts made from composite materials. A peening system with multiple pins provides compaction over irregular surfaces, providing superior performance as compared with traditional compaction rollers. The apparatus that carries out the techniques include a tape dispensing system, a heating system, a peening system, a processor and a memory coupled to the processor. The memory contains instructions that when executed by the processor perform the steps of: dispensing a first ply of thermoplastic composite tape over a mandrel; dispensing a second ply of thermoplastic composite tape on the first ply; and peening the second ply onto the first ply, such that the second ply is bonded to the first ply.
