The weighing inspection machine is an automatic weighing inspection equipment for the production line, mainly used for dynamically inspecting whether the product weight meets the standard requirements, thereby determining whether there are missing components, accessories or overloading situations in the product packaging. It can quickly conduct weight inspection or weighing on the items on the production line, display the detected weight and quantity in real time, and show the inspection results. It can automatically count, automatically reject non-conforming products or give an alarm when encountering non-conforming products. It can be equipped with a computer touch screen, a Chinese window, a friendly human-machine interface, and functions such as daily and monthly report query and printing. The automatic Sorting machine allows passing items to be released, and for items with weight non-conformity, either an alarm is issued or they are pushed out of the conveyor belt by the sorting mechanism. It can replace the manual sampling inspection on the production line and can perform inspections on all passing items without exception, making it a very suitable measuring device for ensuring product quality. The system determines the weight, checks whether it meets the specified weight requirements, and gives prompts of qualified, overweight, or underweight, or performs corresponding non-conforming product rejection actions (according to user requirements). The non-conforming products are pushed out of the production line when the control system gives the instruction of non-conforming products. The control system has functions such as standard weight detection, counting, alarm, and sorting. It can also have the function of graded sorting (customizable). When items of different weight specifications are conveyed on a conveyor belt, they can still be weighed. 

During the process of the weighing selection machine passing through the weighing platform along with the conveyor belt and the change of the measurement signal, the measurement signal consists of the weighing signal of the object and the interference signal. The measurement signal enters the sorting state through the sorting conveyor belt. Based on the detection results, the processing control system issues instructions to make the overweight or underweight barriers of the sorting system act or not act, achieving the purpose of automatic sorting. If the instruction given by the processing control system is for overweight products, the overweight barrier will move to the right under the action of the electromagnet, and the overweight products will fall to the right under the action of the conveyor belt. If the instruction given by the processing control system is for underweight products, the underweight barrier will move to the left under the action of the electromagnet, and the samples will fall to the left under the action of the conveyor belt. If the signal given by the processing control system is qualified, the overweight barrier and the underweight barrier will not act, and the qualified products will fall in the middle under the action of the conveyor belt. Thus, the purpose of automatic sorting is achieved.

The online weighing machine starts to determine the weight when an object passes the measurement platform. The system automatically measures whether the weight meets the specified weight requirements and gives alerts of qualified, overweight, or underweight, or performs corresponding non-conforming product sorting actions (according to user requirements), pushing out the products that do not meet the regulations from the production line. The sorting scale has functions such as weight measurement, classification statistics, alarm screening, and weight grouping. The purpose of the online weighing scale is to configure the weight selection machine at the end of production instruments and automatic packaging and other production lines to measure and sort the products manufactured by the sorting scale, preventing non-conforming products from leaving the factory, analyzing the measurement data to control production volume, and responding to the data guarantee value to the production instruments, and using this control production instruments to prevent unnecessary raw material losses. The weighing selection machine calculates the weight of items on the production line using a high-speed dynamic weighing reading method, accurately checking products with weight non-conformity in the continuous production line, and performing control such as online judgment or automatic weight rejection according to this, especially suitable for checking if there are missing items or abnormal weight errors of individual items in packaged products. The packaged objects are measured by the weighing scale for weighing, and those that meet the standards are sent back to the original conveyor belt, while the unqualified products are removed (or the machine stops automatically). At the same time, it has the functions of classifying and counting the items as required, automatically providing feedback signals to adjust the repair and feeding facilities, displaying fault alarm indications in Chinese, and showing various statistical graphs. This can reduce manpower, improve work efficiency, prevent unnecessary losses caused by excessive packaging or customer dissatisfaction due to insufficient weight, thereby enhancing customer satisfaction, and is an indispensable quality inspection equipment for automatic production lines and packaging lines.
