Description
Product Introduction
Manufactured in accordance with GB/T 20991, GB 21146, GB 21147, and GB 21146, this equipment is primarily used for testing the strength and tensile properties of occupational footwear, protective footwear, and safety footwear. It is widely employed by specialized labor‑protection‑equipment supervision and inspection stations, research institutes for workplace safety, product quality‑inspection agencies, and manufacturers of safety and protective footwear.
Product Features:
1. The entire machine adopts a single-arm structure, with an integrated drive system comprising a stepper motor and a speed-regulating mechanism that powers a synchronous belt reduction unit; the reduced-speed output drives a ball screw to generate the loading force.
2. The force measurement system comprises a high-precision sensor, a measurement amplifier, an A/D converter, a regulated power supply, and other components, ensuring the accuracy of the measurements.
3. The displacement measurement system comprises an optical encoder, a pulse-width shaping circuit, and a computing circuit, ensuring the accuracy of the measurements.
4. The controller employs a dedicated large‑screen LED display, allowing all parameters to be set independently as needed. The LED screen provides real-time monitoring of the testing process and displays the locked test results, while also showing the force–displacement curve in real time.
5. Equipped with overload protection, upper and lower limit protection, and other functions.
6. Standard configuration includes one set of tensile fixtures for bonding strength testing of shoe soles and uppers; optional accessories include a tongue‑shaped tear‑strength fixture, a parallel‑jaw fixture, and a 50 mm‑wide tensile fixture.
