The Jiangdu Jingzhuo tensile machine mainframe consists of the motor and controller, ball screw, guide column, moving beam, limit device, etc. The mechanical transmission sequence is as follows:
Motor - Timing Belt Pulley - Screw Jack - Test Bench
4.2.2 Force Measurement System: Tension sensors are installed on the moving crossbeam of the main unit, with the lower end of the sensors connected to the upper clamp. During the test, the force on the specimen is converted into an electrical signal by the force sensor and input into the microcomputer acquisition and control system.
4.2.3 Automatic Extension Tracking Device: This device is used to measure sample deformation, consisting of two nearly frictionless tracking clamps that hold the sample. As the sample is subjected to tensile force and deforms, the distance between the tracking clamps also increases correspondingly. The tracking clamps convert the linear motion into rotational motion through a rope and pulley, and the displacement is then converted into an electrical signal input into the microcomputer acquisition and control system by the tracking encoder.
4.3 Limiting Protection Device and Clamp
4.3.1 Limiting Protection Device
The limit protection device is a crucial component of this machine. The main unit is fitted with a limit rod, which is equipped with two adjustable collars that can move up and down. During the testing process, when the stopper and the collar touch, the limit rod will be moved, enabling the limit device...
Cut off the passage in this direction, the main engine will stop running. At this point, running in the opposite direction will allow the test machine to operate normally. Adjusting the position of the stopper on the limit rod can limit the travel of the moving beam, providing greater convenience and a more reliable safety protection for conducting tests.
4.3.2 Jig
Our company offers a variety of general and specialized clamping fixtures for sample holding, including wedge jaw clamps, wrapped wire clamps, film stretching clamps, and paper stretching clamps, among others. These are suitable for holding materials such as sheets, strips, foils, strips, wires, fibers, plates, bars, blocks, ropes, fabrics, and meshes for different material property tests, and can be customized according to customer requirements.
 
5. Installation and debugging
 
5.1 Mechanical Installation
Position the main unit vertically at the usage location, adjust the ground screws at the bottom of the main unit, and check the worktable's level using a level (longitudinal and lateral levelness of 0.2/1000).
5.2 Electrical Installation
5.2.1 Plug the force sensor plug into the force sensor interface, and the displacement sensor plug into the displacement sensor interface.
5.2.2 Upon completion of the aforementioned work, the system can be powered on. There is a boat-shaped switch on the back panel of the microcomputer collection system. Place the switch in the 'on' position to connect the power supply.
5.2.3 Connect the main power supply, then rotate to engage the pop-up power switch.
5.2.4 The microcomputer system must be preheated for 20 minutes after powering on before it can operate normally.
 
6. Instrument Usage and Operation
 
6.1 First, check and confirm that the mainframe and microcomputer control system of the testing machine are properly and correctly connected with the cables.
6.2 Rotate and press the emergency stop button on the main power of the rotating pop-out tester, use it to immediately stop or shut down the machine. Turn on the power of the microcomputer control system.
7、GeotextileTensile TesterEnclosed
7.1 One-year warranty certificate for tensile testing machine and a Chinese operating manual each.
7.2 Randomly include a set of standard tensile testing machine fixtures (other fixtures available for selection).

7.4 A set of brand-name computers, one color printer
8. Cautionary Notes
8.1 Before powering on, check the connections between the CNC system and the main machine, including cables, plugs, sockets, and power plug sockets, for correctness and tightness. Confirm they are correct before powering on (e.g., a loose ground wire under the power socket in the CNC system controller can cause the main machine to lose control). Always remember the power-on sequence: first, power on the main machine of the test machine, then the CNC system power. When shutting down, turn off the main machine power of the test machine first, then the CNC system power. Do not remove any plug after powering on.
8.2 It is crucial to check the position of the upper and lower limit position bushes, ensuring a certain distance between the clamps to prevent damage to the machinery due to incorrect operation or loss of control of the main unit, especially the sensors.
Do not press any keys on the microcomputer control system during the testing process.
8.4 Select the fixture based on the specific test conditions to prevent damage to the fixture.
8.5 In case of an unexpected power outage, please immediately shut down all power sources and restart in order only after confirming stable power supply. Frequent and multiple interruptions in power can easily damage the microcomputer control system and the motor speed regulation system.
8.6 Do not stand far from the machine while the main unit is operating.
8.7 The input tensile speed value must match the actual tensile speed of the testing machine, especially during tearing and peeling tests.
8.8 Do not perform tensile testing when the breaking force value of the unclear sample is not specified, otherwise the sensor may be damaged due to overload.
