Paper straw stiffness tester
This testing machine is specifically designed to measure the stiffness performance of paper straws, which complies with the national standard GB/T 44833-2024. Under the specified test conditions, the two ends of the paper straw are subjected to a supporting force, and a vertical force of a certain speed (25 ± 2) mm/min is applied to the midpoint of the paper straw. The maximum force when the paper straw is folded is taken as the stiffness of the paper straw.
The paper straw stiffness tester consists of a lifting device, a sensor, a downward pressure head, a support seat, a horizontal sliding table, etc. The host lifting device is driven by a motor to move the sensor on the screw up and down, and a lower pressure head is fixed below the sensor. The bottom of the pressure head of the instrument is V-shaped with an angle of 70 ° and a rounded corner radius of 0.5mm. The horizontal slide table is engraved with a digital ruler with a resolution of 1mm. The middle of the support seat is a V-shaped groove with an angle of 120 °, and the V-shaped inclined edge is chamfered at a 45 ° angle. The length of the chamfered right angle edge is 0.2mm.
Introduction to the functions of each part of the monitor:
LCD screen: displays force values, peak values, displacement, velocity, prompts, test curves, etc.
The LCD screen is a touch screen, and all functions of the experiment can be completed by clicking on the text or images on the LCD screen,
Function and Features:
1. Adopting a 5-inch high-definition touch screen and microcomputer control
2. Supports both Chinese and English operating systems,
3. Test shutdown mode, reaching displacement, reaching deformation, reaching force value, and force value units include KN, N, Kg, Kgf, Ibf. Choose from 1 to 3 decimal places and various units such as decimals
4. The deformation units include m, dm, cm, mm, and in. Select 1 to 3 decimal places
5. Strength units include Pa, kPa, MPa, and bar. Select 1 to 3 decimal places
6. The precision ball screw transmission system, with dual linear guides on both sides, greatly improves the accuracy of transmission displacement and can achieve stepless speed regulation function
7. The intelligent computing test results have three major testing functions: maximum value, average value, and real-time value
8. Equipped with a miniature silent printer, the test results can be grouped for statistical analysis and output
9. The system comes with overload protection, limit protection, emergency power-off protection, and zero fault human operation
