Abstract

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.

Description

technical field

[0001] The invention relates to the technical field of yarn processing equipment, in particular to an automatic yarn elastic recovery testing device. Background technique

[0002] Yarn is a kind of textile, which is processed into products of a certain fineness with various textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into staple fiber yarn, continuous filament, etc. The strength is closely related to the fastness and production efficiency of the fabric. The strength is the basis of the elongation of the fabric. Therefore, the elongation of the whole wool yarn and wool is an important indicator of quality. Since the elongation directly affects its quality, the requirements must be appropriate. If the strength and elongation are too large, the wool yarn and wool will relax, and the strength will decrease. If the strength and elongation are too small, the strength will increase and the wool and ...
