The invention relates to the technical field of
yarn processing equipment, and discloses an automatic
yarn elastic
recovery degree testing device, which comprises an operation base plate and a testing pressing block, wherein a fixed spool is fixedly connected to the top of the operation base plate, a limiting spool is fixedly connected to the top of the operation base plate, and a limiting clamping groove is formed in the limiting spool; a winding clamping spool is movably connected into the limiting clamping groove, an
electromagnet is fixedly connected into the limiting spool, and a driving motor is fixedly connected into the operation base plate. According to the automatic
yarn elasticity
recovery degree testing device, after the working
voltage of a piezoresistor is reached, a driving motor drives a rotary driving shaft to rotate, so that a rotating block freely rotates in a wave-shaped groove, a driving supporting rod is driven to reciprocate up and down, yarn is pressed downwards through a testing pressing block, and the reciprocating
elasticity testing process is achieved; and when the yarn elasticity
recovery value reaches the limit, the yarn loses elasticity, the
dielectric plate slides down again, the driving motor is turned off, the test process is completed, and the test result is recorded.
