Checkweigher when the items through the load cell, the load cell records the weight of the size, so that after the analog collection of signals through the conversion needs. Digital signals through the microprocessor processing display, the current display equipment are to apply the liquid crystal display, when the collection of weight data, these data through the microprocessor can be analyzed, sorted to meet the requirements of the weight of the simplest and most common is the current widely used small electronic scales. Used in production lines to automatically detect whether the weight of the product is within the given range, and automatically reject substandard products and alarm. There are front and rear transition conveyor belts, scales, gripping and dialing mechanisms, control systems and other components.

Checkweigher can be selected does not meet the requirements of the set weight value, with the conveyor belt and reject equipment to do not meet the requirements of the weight of the production of mouth separation, to meet the requirements of the pass. Has included a lot of today's needs of the function, using the world's advanced digital weighing unit, to achieve high-speed, stable measurement. Patented scale frame structure ensures accuracy and stability. Multi-mode LCD graphic display operating system, Chinese, English and Korean operating interface, easy to learn. Powerful statistical function to record the inspection data of each shift. Adopting dismounted conveyor belt, easy to maintain automatic counting, automatic rejection of nonconforming products or alarm when encountering nonconforming products. Testing standard weight can be set, real-time display of testing weight and quantity, and display of inspection results.

After the checkweigher gets the weight signal of the product, the system will compare it with the pre-set weight range to sort the product, and the sorting type will be different according to the application, and there are mainly the following types: non-conforming products are rejected, and overweight and underweight are rejected separately, or conveyed to different places, and sorted to different weight categories according to different weight ranges.

Checkweigher classification device is based on the role of the control device issued by the sorting instructions, when the goods with the same sorting signal through the device, the device action, so that change the direction of operation in the conveyor weighing device into the other conveyor or into the sorting of the roadway. There are many kinds of sorting devices, generally there are several kinds of push-out type, floating type, inclined type and branch type, different devices for sorting goods packaging materials, packaging weight, the smoothness of the bottom surface of the packages and so on do not have exactly the same requirements.

The grading machine utilizes dynamic weighing technology to detect the weight of the product, and the application of different weight sensors can get different detection accuracy of the weight testing machine, which determines the detection accuracy and operational stability of the weight grading machine. The range range of the weight sensor determines the weighing weight and scale of the weight grading machine. Meanwhile, the precision of the weight sensor also affects the precision of the weight sorter.

Sorting machines can be integrated with various packaging production lines and conveyor systems, mainly used for on-line detection of whether the weight of the product is qualified or not, and whether there are missing parts in the package. Or according to the different weight of the items to be conveyed to the corresponding weight range area. Generally consists of control device, sorting device, conveying device and sorting roadway. The role of the control device is to identify, receive and process the sorting signal, according to the requirements of the sorting signal to instruct the sorting device, according to the variety of goods, according to the location of the goods delivered or according to the category of the owner of the goods for automatic classification.

Detection machine can accurately detect the weight of unqualified products in the continuous production line, according to its implementation of on-line judgment or weight automatic sorting control, qualified to return to the original conveyor belt, unqualified will be rejected (or alarm shutdown), and has the classification and statistics according to the settings. The hardware of the weighing system mainly consists of computer, signal detection part, signal conditioning circuit, data acquisition card part, control part and actuator part.

The inspection machine selects the continuous dynamic automatic weighing method to check the net weight of the objects, with alarm or fully automatic removal organization, thus achieving the net weight inspection without shutting down the machine on the production line. It is suitable for the discharge of bags and cartons. When the raw material is transferred to the middle of the weighing platform, the working pressure is applied to the load cell, which deforms and changes the characteristic impedance, outputting an altered pulse signal. This signal is amplified by an operational amplifier and output to a converter, which converts it into a convenient analog signal output to a microcontroller for calculation and manipulation. Based on key commands and its optimization algorithms, such results are exported to the display, which shows information about the net weight of the information object.

The role of the automatic heavy machine is according to the sorting instructions issued by the control device, when the commodity with the same sorting signal passes through the device, the device acts to change the running direction of the automatic detection machine into other conveyors or into the sorting road. Its main function is to make the goods to be sorted through the control device, the measurement and detection machine on both sides, generally to connect a number of sorting crossings, so that the classified goods slide down the main conveyor (or main conveyor belt) for subsequent operations.
