AB- 105 How to adjust the air pressure of the cutting belt before and after the linear edge banding machine?

Hello! This is Mr. Zhou from Foshan Xianda Machinery of Huali Company. According to your description, I will answer your questions about function and adjustment in detail. ! ! The air pressure of the fine-tuning assembly is completed by three regulating valves at the same time. Generally, the downward pressure is 2-3 bar, and the upward pressure is about 3-4 bar. The control valve without instrument is the pressure safety valve under the cutting head. If the downward pressure is too large, it is easy to make the workpiece fail to keep up with the speed of the cutting saw, resulting in inaccurate cutting head; If the downward pressure is too small, it is easy to impact the workpiece, make the workpiece move and even damage the front saw; Excessive upward pressure may damage the front saw drum, the drum support screw and the slide seat. 2 The downward pressure of the rear saw is also regulated by the regulating valve, which is generally around 1-2bar. If the downward pressure is too large, it is easy to damage the workpiece; if the downward pressure is too small, the cutting saw can't keep up with the speed of the workpiece, resulting in inaccurate trimming; The upward pressure is regulated by the one-way regulating valve on the rear saw cylinder. If the upward pressure is too high, the cylinder, the cylinder support screw and the slide seat will be easily damaged. If the upward pressure is too small and the feed is too fast, the conveyor belt will automatically stop (automatic protection is normal) and the back saw may be damaged (automatic protection may be abnormal). Solution: 1 Adjust the pressure regulating valve at the inlet and outlet of the rear trimming cylinder to reduce the speed and intensity of downward trimming. 2. Adjust the pressure of the pressure regulating valve upstream of the front header to make it softer. In addition, the position of the travel switch of the downstream signal in the front header is wrong or damaged. If the board does not touch the travel switch or the touched switch is broken when it travels to the predetermined position, the front header will bite the board without downward signal. It is required to adjust the position of the travel switch or replace the travel switch.
