What are the parts of the automatic weighing machine and what is the working principle of the weighing machine
Do you know the working principle of the automatic weighing machine and what parts the weighing machine consists of? After collecting and sorting, the editor prepared this article about the working principle of the weighing machine and the structural components of the weighing machine for everyone. The automatic weighing machine is composed of electronic components, weighing sensors, amplifying circuits, AD conversion circuits, single-chip circuits, display circuits, keyboard circuits, communication interface circuits, stabilized power supply circuits and other circuits. Weighing machine workflow: When an object is placed on the weighing pan, pressure is applied to the sensor, the sensor is deformed, so that the impedance changes, and the excitation voltage is used to change at the same time to output a changing analog signal. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter. Converted into a digital signal that is easy to process, output to the CPU operation control. The CPU outputs this result to the display according to keyboard commands and programs. Until this result is displayed. What is the working principle of the automatic weighing machine? 1: During the feeding process, the product enters the feeding conveyor, and the speed setting of the 2113 feeding conveyor is determined by the distance between the products and the required speed. The purpose is to ensure that there can only be one piece during the working process of the automatic weighing machine. The product is on the weighing platform. 2: Weighing process When the product enters the weighing conveyor, the system recognizes the product to be tested into the weighing area according to the 5261 external signal, such as the photoelectric switch signal, or the internal level signal. 4102 According to the running speed of the weighing conveyor and the length of the conveyor, or according to the level signal, the system can determine the time when the product leaves the weighing conveyor. From the product entering the weighing platform to leaving the weighing platform, the load cell 1653 will detect the signal, and the controller selects the signal in the signal stable area for processing, and the weight of the product can be obtained. 3: Rejected special trip. After the controller gets the weight signal of the product, the system will compare with the preset weight range and reject the product. The rejection type will be different depending on the application, and there are mainly the following types: 1. Reject unqualified products. 2. Eliminate overweight and underweight separately, or transport to different places.
