Description

Technical Field

[0001] The utility model relates to the technical field of glow-wire testing machines, in particular to a glow-wire testing machine. Background Art

[0002] The glow wire tester is a test device used to evaluate the safety performance of electrical equipment and consumer products. It simulates the glowing components that may be generated by equipment or consumer products under abnormal conditions to test whether they will emit dangerous temperatures or heat. The glow wire tester is widely used in the fields of plastics, rubber, textiles, chemicals, etc. to measure the melting temperature of materials to determine their performance and quality.

[0003] When using the existing glow-wire tester, generally ten samples need to be prepared. During the experiment, one sample is selected and fixed on the carrier, and then the door of the glow-wire tester is closed, and the resistance wire ring is heated to the set temperature. Then the carrier drives the sample close to the resistance wire ring, so that the top of the resistance wire ring contacts the sample for the standard required time, and then observes its state. After the experiment is over, the sample is replaced and the experiment is repeated. During the whole test process, the operator is always required to be by the side, which wastes manpower. At the same time, because the glow-wire tester does not have automatic and continuous test performance, the efficiency of the whole test process is low. Utility Model Content
