Fresh-Keeping Box Food Packaging Bag Tensile Testing Machine

1. Product Introduction

The Freshness Box, Food Packaging Bag and Cup Peeling Force Testing Machine are all new-generation microcomputer-controlled electronic universal testing machines specially designed for colleges and research institutes. The mainframe and accessories of the testing machine are designed by drawing on advanced international technologies. They are aesthetically pleasing in appearance, easy to operate, and have stable and reliable performance. The computer system is controlled by a controller, which drives the stepping motor to rotate through the speed regulation system. Then, it drives the moving crossbeam to rise and descend through the precision screw pair, completing various mechanical property tests such as tensile, compression, bending, and shearing of the test samples. They are pollution-free, have low noise, high efficiency, and have a very wide speed adjustment range and crossbeam moving distance. In addition, they are equipped with a wide variety of test accessories, which have very broad application prospects in mechanical property tests of metals, non-metals, composite materials and products. This machine is widely used in material inspection and analysis in the fields of building materials, aerospace, mechanical manufacturing, wires and cables, rubber and plastics, textiles, home appliances, etc. It is an ideal testing equipment for research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration departments.

This machine adopts a fully digital servo speed control system with high precision and stable performance, and a stepper motor as the driving system. The controller serves as the core of the control system. The control and data processing software with WINDOWS as the operation interface enables the display of the test force, peak test force, crossbeam displacement, test deformation and test curve on the screen. All test operations can be automatically completed through the mouse on the computer. The excellent humanized design makes the test operation more convenient. Based on the above technologies, this machine can nearly perfectly achieve closed-loop control of parameters such as test force, deformation and displacement, and can realize control modes such as constant stress, constant strain and constant displacement. Moreover, various control modes can be smoothly switched. This machine fully meets the requirements of the national standard GB/T228-2002 "Metal Materials Tensile Test at Room Temperature", and at the same time, it can be used for testing and data processing according to various standards such as GB, ISO, JIS, ASTM, DIN and provided by users, and has good scalability.

2. Main Functions and Features

1) Host

1.1 The speed control system adopts servo motor and independently developed deceleration system, which is stable and reliable with protection devices such as overcurrent, overvoltage and overload. The speed control range can reach 0.05 - 500mm/min.

1.2 The transmission part adopts circular arc synchronous toothed belt and precision lead screw pair for transmission, which is smooth, low in noise and has high transmission efficiency.

1.3 The universal joint adopts cross pin structure and has the function of limiting swing angle. On the one hand, it is convenient for sample clamping and ensures the concentricity of the test. On the other hand, it effectively eliminates the influence of irregular samples on the sensor.

2) Control system, operation software and data processing system

2.1 Computer control system, featuring high integration, stable performance and convenient adjustment. It can collect real-time experimental data, display real-time dynamic curves of experimental characteristics, and save experimental data files in the form of Access common database or SQLserve large database, facilitating resource sharing and network management for customers, as well as re-analysis by users. For various word2000 reports customized by users, this software can easily access them, solving the problem of different users or the same user having different needs for test reports at different times. This software can process raw data of test force, displacement, time and deformation, as well as derived curves.

2.2 Protection functions: This machine has two types of limit protection methods: software and mechanical. The proportion of automatic shutdown when exceeding the maximum load can be dynamically set; it has multiple protection functions such as overcurrent, overvoltage and overload.

2.3 Automatic indication can be achieved for load and deformation channels, which is intuitive and convenient.

2.4 Curve display can be achieved in hierarchical form for batch tests, and curves can automatically follow.

2.5 This software can realize user-defined speed setting and computer adjustment of speed. It can also achieve high-precision speed calibration and adjustment of speed gears and encoding at any time.

2.6 Real-time display of various parameters during the test process: test force, deformation, displacement and curves during the test can be displayed in real time.
