Pure pure cotton sanitary napkin equipment in practice often requires continuous optimization, development and replacement in the process of use. The following is an example of the change and adjustment of the position of the reference point.
The zero point of the pure cotton sanitary napkin equipment is set at the factory and is a fixed point that cannot be changed. The reference point is set to find the zero point of the pure cotton sanitary napkin machine during operation. This point is either in the same position as the zero point or offset from the zero point. It is set at the factory. If an alarm condition occurs during operation, the reference point returns abnormally and the correct position cannot be found. This is a fault caused by the coordinate axis being out of position. It can be reset by operating the reset button.
In fact, when the pure cotton sanitary napkin machine returns to the reference point, the proximity sensor generates a zero pulse each time the screw is rotated. Therefore, which zero pulse should be used as the reference signal? At the specific position of the coordinate axis, we can install the hardware block and the travel switch as a reference point reduction switch. Since the switch allows for initial positioning, the sensor can detect multiple zero pulse signals by determining the signal to return to the reference point via the deceleration switch.
Error compensation technology is commonly used in the application of pure cotton sanitary napkin equipment. Currently, the ability to identify error sources and the ability to compensate for errors after they are generated is mainly used for practical applications. In the processing of pure cotton sanitary napkin equipment, there are many practical influencing factors, including the indoor temperature of the production plant, indoor ambient air quality, installation errors, temperature errors, etc. In the work, the processors gradually realize the space error, high frequency error, etc.
In the actual machining process in the workshop, different types of tools and workpieces have relative movements during operation, so dynamic errors are generated, and such dynamic errors should also be compensated in real time. Therefore, in order to improve the machining level, in addition to compensating the basic static error, the dynamic compensation technology should be studied to meet the machining requirements and ensure the product quality.
Therefore, for error compensation, the basic idea is to reduce the appearance and dimensional errors of the produced products by displaying the input system, and after input, the electronic control system theoretically calculates and obtains the compensation parameters, and then controls the compensation. Generally speaking, the accuracy of CNC is high, and its error compensation can be divided into two aspects, one is software error compensation, and the other is hardware error compensation. In order to improve the processing accuracy, it should be used for a long time.
At present, for the feeding system of pure cotton sanitary napkin equipment, the positioning accuracy should also be studied in depth. The accuracy of the feeding system is related to the whole production process and plays a great role in promoting the overall performance of the improvement. By testing the positioning accuracy of the feeding system, we can get the error source of the feeding system, how to reduce the error, improve the accuracy, and propose error compensation methods to improve the overall work performance. After the error is generated, the error value is analyzed theoretically, and the parameters of each axis of the feed system are repeatedly corrected, and the corrected value should be followed up slightly to improve the positioning accuracy.
In recent years, pure cotton sanitary napkin equipment has conducted a lot of research in various error compensation, and has made sufficient progress and development. However, there are still certain gaps in universality, systematization and practicality. In the future, we should explore and study how to establish a comprehensive model of errors, study different types in depth, and establish and develop low-cost error accuracy detection and compensation methods.
