Brief operating instructions

1. Introduction

1、 Purpose:

corrugatedCarton ring pressure testing machineBy using high-precision sensors for sensing, the ring compression strength, vertical compression strength, bonding strength, and flat compression strength of paper and cardboard can be tested. At the same time, the tensile strength can also be tested and the test values can be directly displayed.

2、 Principle:

The corrugated cardboard ring compression testing machine is an electronic display ring compression/tensile testing machine, which uses a motor to drive a screw to move the fixture. The test fixture is placed between the upper and lower fixtures, and then a specified speed is applied. When the upper fixture compresses the sample downwards, the load element at the upper end of the upper fixture feels the pressure; The tensile test involves the upper fixture moving upwards and the lower fixture moving downwards. The fixture also senses pressure and converts the force into a voltage signal, which is then transmitted to the display. The result is automatically displayed on the display when connected to a LOAD CELL force sensor.

2. According to the standards

The design of the corrugated cardboard ring pressure testing machine meets the requirements of standards such as GB/T1914.

danger

The input voltage error range is within+10% and the instrument is properly grounded to prevent damage caused by instrument leakage.

2、 Operating environment requirements: Room temperature conditions.

3、 This instrument needs to be installed and positioned on a horizontal ground.

V. Test Specifications

1、 Operating instructions:

1.The machine must be connected to a 220V+5% 50Hz power supply and have good grounding protection measures.

2.After turning on the power switch on the panel, the panel will be powered on and the monitor will automatically open the program.

3.Confirm whether the travel protection device of the machine is effective and reasonable.

4.Place the test specimen in the middle of the fixture, select the diameter of the inner disc according to the thickness of the specimen, and place it on the specimen seat (the inner disc indicates the suitable thickness of the specimen in mm). Carefully insert the specimen into the specimen seat and ensure that it is inserted to the bottom as follows. Press the test key and the up or down key to start the test.

5.It is strictly prohibited to have direct contact between the upper and lower fixtures, or to test with metal specimens.

6.During the testing process, if there are any abnormal conditions, press the stop button, turn off the power, and immediately notify the maintenance personnel for inspection. It can only be used after troubleshooting.

7.After receiving the display signal, the printer can press the print button to print the current date, time, number of times, and maximum pressure value. (For detailed operation, please refer to monitor operation and printer operation)

8.The monitor receives the signal from the pressure sensor on the top of the pressure plate and displays the highest pressure value at that time. Press the reset button to clear the numbers on the display. Press the peak button to record the maximum value of the test during testing.

threeDetermination of results of corrugated cardboard ring compression testing machine:

1.Calculate the flatness values of longitudinal and transverse forces separately

2.Calculate the ring compression strength:

R=F/L

In the formula:R- Ring compression strength, kN/m

FThe maximum force at the time of sample failure, N

L- Sample length, mm

3Calculate the formula for edge compression strength:.

R=F×10³÷L

In the formula: R - edge compression strength unit N/m;

F- The sample is subjected to the maximum pressure N;

L- The length dimension of the sample is mm.

The unit of edge compression strength is N/m, while the length of the specimen is 100mm, which requires data processing. Firstly, convert 100mm to 0.1m and calculate according to the above formula. Assuming that the arithmetic mean of the maximum pressure borne by the sample during the test is 680N, after data processing, it is:

680N/0.1m=6800N/m

So, according to the above formula, the edge compression strength value of the sample is:

6.80×103N/m

The edge compression strength of corrugated cardboard directly affects the support strength of corrugated cardboard boxes. The production process of corrugated cardboard, as well as factors such as the structure, shape, and quality of adhesive, can all affect the edge compression strength of corrugated cardboard.
