Microcomputer controlled universal testing machine for wood-based panels

Microcomputer controlled universal testing machine for wood-based panels

The microcomputer-controlled universal testing machine for wood-based panels is developed for testing various physical and chemical properties of wood-based panels and decorative wood-based panels. It can meet the requirements of GB17657-2013 Test Methods for Physical and Chemical Properties of Wood-based Panels and Decorative Wood-based Panels. It can carry out internal bonding strength, surface bonding strength, tensile strength test, bending resistance test, static bending strength and elastic modulus test, screw holding force test, and shear and bending test of wood-based panels, It is the ideal test equipment for quality inspection departments and production enterprises at all levels of wood-based panels, and can provide you with accurate test results.

Mechanical process structure

The main frame mainly consists of a base, three columns and a lead screw to form a single-arm frame structure; The transmission and loading system uses AC servo motor and synchronous toothed belt reducer to drive the high-precision ball screw to rotate, and then drive the moving beam to realize loading. This machine has beautiful shape, good stability, high rigidity, high control precision, high working efficiency, low noise, energy conservation and environmental protection.

Control and measurement system

The machine adopts the advanced Test4.0 full-digital closed-loop control system for control and measurement, and uses computers to dynamically display the test process and test curve, and to process data. After the test, the curve can be analyzed and edited again through the graphics processing module, and the performance reaches the international advanced level.

1. Realize special closed-loop control of displacement, deformation and speed.

During the test, the test speed and test method can be flexibly changed to make the test plan more flexible and substantial;

2. Multi-layer protection: with software and hardware two-level protection functions, it can realize multiple safety protection methods for the tester, such as overload, overcurrent, overvoltage, undervoltage, overspeed, limit, etc;

3.3 high-speed 24-bit A/D conversion channels, with effective code value resolution up to ± 300000, realize internal and external non-shift, and maintain the resolution throughout the process;

4. USB or serial communication is adopted, and data transmission is stable and reliable, with strong anti-interference ability;

5. Three pulse signal acquisition channels are adopted (three pulse signals are one channel of displacement and two channels of large deformation signals respectively), and the most advanced quadruple frequency technology is adopted to amplify the number of effective pulses by four times, greatly improving the signal resolution, and the maximum acquisition frequency is 5MHz;

6. One servo motor digital drive signal, the maximum frequency of PWM output is 5MHz, and the minimum is 0.01Hz.
