Fresh-Keeping Box Food Packaging Bag Compression And Pressure Resistance Testing Machine

1. Product Introduction

The fresh-keeping box food packaging bag compression and compressive strength testing machine is a new generation of microcomputer-controlled electronic universal testing machine specially designed for colleges and research institutes. The design of the main machine and accessories of the testing machine draws on advanced international technologies. It has an attractive appearance, is easy to operate, and has stable and reliable performance. The computer system is controlled by the controller through the speed regulation system to drive the stepper motor to rotate, and then drives the moving crossbeam to rise and descend through the precision screw pair to complete various mechanical property tests of the specimens such as tensile, compression, bending, and shearing. It is pollution-free, has low noise, high efficiency, and has a very wide speed regulation range and crossbeam moving distance. In addition, it is equipped with a wide variety of test accessories, and has very broad application prospects in the 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.

3. Main Functions and Features:

1. Mainframe:

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

1.2 The transmission part uses circular arc synchronous toothed belts and precision screw pairs for transmission. The transmission is smooth, with low noise, and has high transmission efficiency.

1.3 The universal joint adopts a cross-pin structure and has a swing angle limitation function. 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, Operating Software and Data Processing System

2.1 The computer control system has the advantages of 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 databases or SQL Server large databases. This facilitates the sharing of resources for customers and network management, as well as re-analysis by users. For various Word 2000 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. The software can process raw data such as test force, displacement, time, and deformation, as well as derived curves.

2.2 Protection Function: 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 also has various protection functions such as overcurrent, overvoltage, and overload.

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

2.4 Batch tests can realize hierarchical display of curves and automatic following of curves.

2.5 This software can realize user-defined speed setting, 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 such as test force, deformation, displacement, and curves during the test process can be realized.

2.7 Software permission hierarchical management function: To improve the security of the software and data, this software can achieve hierarchical management function by setting different passwords for protection.

2.8 Result reproduction function: After the test operation is completed and saved, the test data can be re-analyzed at any time in the future according to the user's needs.

2.9 Test and data display, storage, analysis and printing can be carried out according to the user's needs for curves such as load~deformation, load~time, load~displacement, displacement~time, and deformation~time.

2.10 Point-by-point traversal function of curves: By clicking on the force and deformation values on the curve with the mouse, various parameters of each point can be obtained.

2.11 Result comparison function: Multiple test curves can be observed simultaneously, and the characteristics of the sample to be analyzed can be compared by superimposing multiple curves and local magnification.

2.12 Force interface: The force channel interface and the test software can be equipped with various sensors according to the user's needs, and calibration, parameter modification, and normal test can be carried out.

2.13 Deformation interface: The deformation channel interface and the test software can be equipped with various types of extensometers according to the user's needs, and calibration, parameter modification, and normal test can be carried out.
