Embodiment Construction

[0015] The inventors of the present invention recommend the following examples. see figure 1 , the yarn sample 5 is divided into bundles according to the regulations, and put into the sample basket 4 after weighing on the electronic balance 1; then several sample baskets 4 are put into the turntable 6 in the microwave heating box 3, The motor 7 drives the turntable 6 and the sample basket 4 equipped with the yarn sample 5 to rotate, or stays at the designated position according to the instruction of the computer 10, and the computer 10 reads the position of each sample basket 4 from the encoder 8; After microwave heating, the moisture absorbed by the yarn sample 5 is rapidly heated up after absorbing the microwave energy due to the large dielectric loss, and is released from the yarn sample 5 from the inside to the outside at the same time, and the powerful exhaust mechanism 2 dissipates the water The gas is quickly discharged from the microwave heating box 3. During the hea...

Abstract

The present invention is fast yarn moisture regain detecting method and apparatus. The yarn sample is first separated into bundle, weighed and set inside sample basket of the matter with very low microwave dielectric loss; and several sample baskets are heated and ventilated inside microwave heating box. Owing to yarn sample with moisture absorbed and great dielectric loss, the yarn sample has fast raised temperature and its water is released from inside and taken out by the fast flowing air. During heating, the yarn sample is weighed regularly until the weight difference between twice adjacent measurements become less than 0.05 %, and the yarn moisture regain is calculated based on relevant formula, stored, displayed and printed.

Description

Technical field: [0001] The invention relates to a microwave drying technology, an object weight automatic detection technology, and a yarn moisture regain rapid detection technology, and is a new type of yarn moisture regain rapid detection method and device. Background technique: [0002] In the process of yarn production and commodity trading, in order to detect the moisture regain of the yarn, the usual method is to wind a 100-meter-long yarn sample into a coil with a circumference of 1 meter and then twist it into a bunch. After weighing Put them into the sample baskets, put 10 bundles in each sample basket, and then put several sample baskets (8 in general) into the electric oven to heat and ventilate, so that the moisture absorbed in the yarn is gradually released. During the heating process, take out the sample basket containing the yarn sample in the oven at regular intervals and weigh it once. When the difference between the weights of two adjacent yarn samples is ...
