The main role of the automatic checkweigher is to make the goods to be sorted through the control device, the measurement of the checkweigher, and automatic checkweigher on both sides of the machine, generally connected to a number of sorting roadway, so that the classification of goods sliding down the main conveyor (or the main conveyor belt) in order to carry out the subsequent operations.

The sorting scale consists of a weighing conveyor, a controller and an inlet/outlet conveyor. The weighing conveyor collects the weight signals and sends them to the controller for processing. The in-feed conveyor ensures adequate spacing between the products by increasing the speed. The outfeed conveyor is used to transport the inspected products away from the weighing area.

The automatic detection machine gives the release of qualified items, and the weight of unqualified products is either alarmed or pushed out by the sorting agency. It can replace the manual sampling inspection on the production line, and can detect all the items passed without exception, which is a very suitable measurement equipment to ensure the quality of the production products.

Inspection machine is an automatic weight inspection assembly line equipment, mainly used for dynamic inspection of product weight is up to standard qualified, so as to determine whether the product package is missing parts, product accessories or more loaded overweight and so on. Can be quickly on the production line items for weight inspection or weighing, testing standard weight can be set, real-time display of the test weight and quantity, and display the test results, automatic counting, automatic rejection of substandard products or meet the substandard products when the alarm, can be equipped with a computerized touch-screen, Chinese windows, man-machine interface friendly, easy to operate, classification of daily and monthly reports query printing and other functions.

When the inspection machine passes through the inspection table, the system will judge its weight, detect whether it meets the specified weight requirements, and make qualified, overweight, underweight prompts, or execute the corresponding non-conforming products rejecting action, and push the non-conforming products out of the production line. It has the functions of standard weight detection, counting, alarm and sorting.

Weighing conveyor will pass through the material on the belt, through the weighing scale frame under the load cell to detect the weight, the feeding controller will be the flow and set the flow rate for comparison, the output signal from the controller to control the frequency converter speed regulation, to achieve the requirements of quantitative feeding. It is an automatic scale that continuously weighs the bulk material on the conveyor belt without the need to subdivide the mass or interrupt the movement of the conveyor belt.

Weighing conveyor is from the weight of the material on the belt, the weighing signal and the speed signal of the belt running together transmitted to the microprocessor weighing controller, automatically calculate the instantaneous flow of the material. By continuously comparing the set flow rate and the actual flow rate, the speed of the belt is adjusted so that the actual material flow rate is kept at the set flow rate value.

The weighing conveyor is used for the quantitative feeding of bulk materials, the feeding process is a spiral rotating continuous feeding, the materials from the user feed bin or other feeding equipment will be transported and through the weighing bridge for weight detection; at the same time installed in the end of the speed sensing screw for speed detection; the detected weight signal and speed signal together into the weighing controller for calculus processing and display in tons per hour unit of instantaneous flow and cumulative amount in tons per hour. Instantaneous flow rate in tons per hour and cumulative flow rate in tons per hour are displayed.

The weighing conveyor utilizes a load cell made of strain resistors for metering. The bearing surface generates a certain amount of pressure, and the material on top of the belt passes through the bearing surface of the lever device. This pressure is transmitted to the load cell through the lever device, and the control device will amplify and process the weight pressure signal sensed by the load cell, and then display it in a digital way. At the same time can be displayed on the digital signal for external human control, so that the measurement of belt scales according to people's actual requirements of the amount of feed automatically change the speed of the belt fast and slow, the given amount of feed tracking, so as to form a belt on the material more, slower, less material faster, no material when the speed of the fastest, and overloaded when the slowest and even will stop the control characteristics.
