In order to eliminate the fault as soon as possible and restore the normal operation of the paper sawing machine, the method of troubleshooting can be adopted, and all the above components that may cause the fault can be inspected step by step from top to bottom. What is the working principle of paper sawing machine in production? Let's follow Xiaobian to understand.
First, check the proximity switch on the running track of the platen. No problem is found. Then, remove the fuel tank baffle and observe carefully. It can be seen that the oil tank is not short of oil, but the oil pan leaks seriously when the paper presser is pressed down. When touched by hand, it was found that one oil return pipe was missing, which led to air entering the oil cylinder during oil supply of the oil pump, resulting in abnormal sound when the paper pressing wheel was pressed down. The solution is: first install the oil pipe, and then press the paper repeatedly, so that the air in the oil path can be discharged smoothly until the abnormal sound disappears.
Next, further in-depth inspection of the hydraulic system that controls the movement of the platen did not find any problems. When checking the mechanical part, it was found that the triangular swing rod on the hydraulic cylinder was not flexible. So tension the tension spring to increase the restoring force, and then repeat the test run. The fault still exists, so it is determined that the problem is here. When it was disassembled, it was found that the internal shaft and bearing were rusted, but the shaft was not damaged. The solution is: replace the bearing, polish the pin shaft to make its surface accuracy meet the use requirements, then install and add lubricating oil, start the test run, and restore the normal operation of the paper sawing machine.
The working principle of the paper sawing machine is relatively simple, and the requirements for the environment are not high. Generally speaking, most offices work with power supply. The ordinary paper sawing machine is equipped with an automatic switching system, and the paper sawing machine automatically rotates to cut paper. Some paper cutters need to press the start button. Then, the paper cutter can be rotated to continue cutting the paper. After the paper is finished, press the "stop / reverse" button to stop the rotation of the saw.
For earlier products, if there is a paper jam in use, you must press the backspace key or the shutdown key to keep the available paper. Most of the paper sawing machines are equipped with overload power-off protection devices, and the motor will stop automatically if it overheats. To stop using, cool the motor. At the same time, when reusing, it should be considered to appropriately reduce the amount of input paper. The more advanced paper sawing machine will stop automatically once it is overloaded, and the automatic paper return is more convenient to use. When the box of the paper sawing machine is full, some machines will automatically sound to remind people to remove paper scraps in time.
