Body Weight Analysis Of Automatic Checkweigher

Jun 29,2022

The automatic checkweigher is a high-precision and high-speed weighing and sorting device. It is an important auxiliary equipment for automated packaging. The use of automatic checkweigher replaces the use of traditional manual weighing and static electronic weighing scales. It can improve the product qualification rate and reduce user complaints. Here is an article about the analysis of the body structure of the automatic checkweigher to help you better use the automatic checkweigher.

Body weight analysis of automatic checkweigher:

The automatic checkweigher consists of a conveyor (metering part), a load cell, a display controller and so on.

1, conveyor

The conveyor consists of a conveyor and a weighing unit. There are various types of conveyors, and belt, chain or roller type can be selected according to the form of the object to be conveyed. The size of the conveyor depends on the size of the object being weighed. The checkweigher weighing platform itself is a separate small conveyor that weighs the item as it passes through the conveyor. Because it is dynamic metering, the metering speed is higher. The transmission part of the conveyor adopts a three-in-one electric roller (ie, the motor, the reducer and the roller are integrated), which can make the weighing platform have a compact structure, reasonable layout and beautiful appearance.

2, load cell

Weighing sensors are also available in a variety of forms, such as differential transformers, resistance strain gauges, and electromagnetic balances. Several precision series checkweighers use resistance-strain sensors that are intoxicated. The advantage is low price, product type. More, the stability is better. The weighing platform consisting of the conveyor is placed on the sensor. The number of sensors is determined according to the size of the weighing platform. The large weight and large size of the table are supported by 4 sensors. The performance is stable and reliable. Small range, A small size countertop can be used with a single sensor to support the countertop.

3, display control

The weight signal sent by the symmetrical quantity sensor is amplified, processed, digitally displayed, and the weight data is compared with a preset value, and then the underweight, overweight, and qualified control signals are issued. The limits of underweight and overweight can be manually set. The display control instrument can display the gross weight, the net weight, the one weighing value after drunk, and the difference between the one weighing value and the set nominal value after drunk. It can also display the total number of pieces weighed, the number of underweights, the number of overweights, and the number of qualified items. The display controller can also carry a variety of statistical information, and can use the communication interface to network useful information to the management computer or print out the report through the printer.

4, rejection device (optional)

According to the packaging form and characteristics of the articles to be inspected, the rejecting device can be divided into various methods such as pushing, tipping, carrying, and diverting, and the unqualified items to be detected are excluded from the production process. The checkweigher consists of a conveyor (metering part), a load cell, a display controller and so on.
