How does an automatic weighing machine work?1
The automatic weighing machine is composed of electronic components, load cells, amplifying circuits, AD conversion circuits, single-chip circuits, display circuits, keyboard circuits, communication interface circuits, and regulated power supply circuits. Mainly used in the production line, it can automatically detect the weight and reject the unqualified products. Workflow description of automatic weighing machine: When the object is placed on the weighing pan, the pressure is applied to the sensor, and the sensor is deformed, so that the impedance changes, and the excitation voltage is changed to output a changing analog signal. The signal is amplified by the amplifying circuit and output to the analog-to-digital converter, converted into a digital signal that is easy to process, and output to the CPU for operation control. The CPU outputs such results to the display according to keyboard commands and programs until such results are displayed. So, how to install the weighing sensor of the dosing machine? The weighing sensor is a part of the dosing machine equipment. The so-called weighing sensor is mainly used to weigh the weight of the material on the dosing machine. The weight sensor is only an accessory of the quantitative feeder equipment, but its function cannot be ignored. Therefore, the installation of the weighing sensor of the quantitative feeder is also very important. So, what problems should be paid attention to when installing the weighing sensor of the quantitative feeder? The weighing sensor of the quantitative feeder should be handled with care to avoid any vibration and shock, so as not to cause the weighing sensor to output signals. If there is a large error, when adjusting the level during the installation process, it is necessary to ensure that its base installation plane is adjusted to a horizontal state with a spirit level. The purpose is to ensure that the force on the sensor is the same. Avoid exposure to sunlight and rain; if the cable needs to be lengthened, it cannot be lengthened by itself. It needs to be soldered at the joint when lengthening, and it must be sealed against moisture; if it is to be used in high-precision applications, it is necessary to weigh it first. The sensor and the instrument are used after preheating for 30 minutes. The manufacturer of the checkweigher machine reminds you to remember: the loading direction of each weighing sensor of the quantitative feeder is determined, and when we use it, we must load the load in this direction . Lateral forces, additional bending moments, and torque forces should be avoided as much as possible.
weigher is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.
