Problems solved by technology
[0003] The purpose of the present invention is to provide a quantitative weighing system, which adopts the method of weighing first and loading later, and solves the problem of weighing accuracy in the dynamic weighing process by adjusting the opening of the solenoid valve, and eliminates the need for material loading. It is impossible to calculate the influence of the weight if it is stuck in mid-air. The error between the weight of the product and the standard weight is small, the accuracy is high, and it has a wide range of application prospects.

The invention relates to a weighing system, in particular to a quantitative weighing system. The quantitative weighing system comprises a weighing sensor, a single chip microcomputer, a touch screen,a communication serial port and an A / D conversion module which are arranged on a weighing platform, wherein a material hopper is arranged above the weighing platform, the lower part of the material hopper is provided with a feeding tube, the feeding tube is provided with an electromagnetic valve, the lower part of the weighing platform is provided with a discharging tube, the discharging tube is provided with an electromagnetic valve 2, a conveying device is arranged below the discharging tube, and the conveying device is provided with a packaging bag. The quantitative weighing system adoptingthe technical scheme of the invention adopts a successive weighing and packaging mode, solves the problem of weighing precision in the dynamic weighing process through adjusting the opening action situation of the electromagnetic valve, eliminates the influence that the material stays in the mid air and cannot be weighed during loading, has small error between the product weight and the standardweight, is high in precision, and has a wide application prospect.
Description
technical field [0001] The invention relates to a weighing system, in particular to a quantitative weighing system. Background technique [0002] Quantitative weighing is widely used in industrial production processes, such as chemical batching process, food packaging process, cement batching packaging process and so on. The traditional weighing mode is to carry out static mechanical weighing first, control the weighing weight through the process of manual continuous feeding or subtracting, and then carry out manual packaging or batching, which leads to extremely low efficiency and great labor intensity for workers , and the accuracy is not high. The emergence of electronic scales has improved the accuracy of static mechanical weighing, but in the dynamic production process, weighing accuracy is a problem. So how to solve the problem of weighing accuracy in the process of dynamic weighing has become a hot spot of current research. In addition, during the material loading ...
