[0002] Quality testing of electric heating tapes is crucial to ensuring their safe, effective, and reliable use. This process typically includes raw material testing, production process control, and finished product testing. Before commissioning, electric heating tapes undergo environmental compatibility testing and mechanical performance testing. Environmental compatibility testing includes low-temperature resistance testing, which tests the tape's performance in low-temperature environments; high-temperature resistance testing, which tests its stability and insulation properties in high-temperature environments. Mechanical performance testing includes tensile testing, which checks the tape's tensile strength; and bending testing, which tests the tape's performance when bent to ensure it is resistant to breakage.
[0003] Existing devices for testing electric heating tapes usually perform mechanical tests and environmental tests separately, and are unable to accurately determine the quality of the electric heating tape when the two are combined.
[0004] Therefore, in view of the above problems, this technical solution proposes an electric heating belt detection device Utility Model Content
[0005] The purpose of the present utility model is to provide an electric heating belt detection device to solve the problems raised in the above background technology.

When testing the electric heating belt, the end positioning plates at both ends are respectively placed in the fixed base and the movable base, and then the electric heating belt is stretched by the movement of the movable base to test its tensile strength. A group of bending push rods are movably set on the test platform between the fixed base and the movable base. The bending push rods move vertically relative to the movable base and are used to directly push the middle of the electric heating belt to test the bending resistance of the electric heating belt. Through the coordination between the fixed base, the movable base, the bending push rods and the high-temperature heater and the low-temperature refrigerator, the coordinated detection of the high and low temperatures and mechanical properties of the electric heating belt is realized, thereby fully reducing the test cost and improving the detection accuracy.
[0007] Compared with the existing technology, the beneficial effect of the present invention is: by setting up a temperature-adjustable testing box, and setting a fixed base, a movable base and a bending push rod inside the testing box, the performance of the electric heating belt is tested under different conditions such as tensile strength, bending resistance, high and low temperatures, so that the electric heating belt can be subjected to multi-faceted high-precision quality testing using a single set of testing boxes.
