AI Technical Summary
Technical Problem
Existing yarn breakage alarm devices for recycled polyester yarn have blind spots in their laser emitter illumination, resulting in poor alarm performance.
Method used
Design a yarn breakage alarm structure including a guide rod, spring, yarn guide ring and micro switch. The displacement of the yarn guide ring triggers the micro switch. Combined with the aluminum alloy yarn guide ring and cooling cavity, the heat of the yarn is reduced by conducting heat through aqueous solution.
Benefits of technology
It improves the accuracy and reliability of yarn breakage alarms, reduces yarn damage caused by frictional heat, and increases production efficiency.

Abstract
The utility model discloses a kind of broken yarn alarm device of regenerated polyester knitted grey cloth, including fuselage, the inside bolt connection of fuselage has mounting plate, yarn breakage alarm structure is installed on the mounting plate.The utility model is provided with guide rod and spring by the both sides of guide ring, when yarn passes, guide ring generates downward displacement, so that spring compression deformation, when broken yarn occurs, spring on guide ring resets and triggers micro switch by pressing block, so that buzzer rings and red light flashes, to remind worker that broken yarn phenomenon has occurred, cooling cavity is opened in guide ring, cooling cavity is filled with aqueous solution by inlet tube, so that the heat generated by yarn friction with guide ring in transmission process is heat conduction, and guide ring is made of aluminum alloy material, with heat conductivity, to reduce the heat of yarn, reduce the phenomenon that yarn burns or breaks due to friction heat, reduce yarn damage.
