How to achieve dynamic weighing on a checkweigher

checkweighers, as a high-precision measuring device, are widely used in many industries such as food, medicine, and chemicals to achieve dynamic weighing. This article will discuss in detail how checkweighers achieve dynamic weighing and its technical principles.

1. Working principle of checkweighers

Checkweighers measure the weight of objects through high-speed, high-precision sensors. During the dynamic weighing process, the sensor converts the gravity of the object into an electrical signal, which is amplified, filtered, and digitized, and then processed and analyzed by the computer system to finally obtain the weight value of the object.

2. Dynamic weighing process of checkweighers

1. Object transmission: Checkweighers are usually used in conjunction with conveyor belts or other transmission equipment to transmit the object to be measured to the top of the weighing platform at a certain speed.

2. Weighing preparation: Before the object is transmitted to the top of the weighing platform, the checkweigher will perform a series of preparations, such as calibrating the sensor, setting the weighing parameters, etc., to ensure the accuracy of the weighing results.

3. Weighing process: When the object is transmitted to the top of the weighing platform, the sensor will immediately sense the gravity of the object and convert it into an electrical signal. After amplification, filtering and digital processing, this electrical signal is transmitted to the computer system.

4. Data processing: After the computer system receives the electrical signal transmitted by the sensor, it will perform a series of data processing and analysis, such as removing noise, calculating the average value, etc., to obtain a more accurate weight value.

5. Result output: The processed weight value will be output to the display screen or other devices for the operator to view and record. At the same time, the computer system can also judge the weight value according to the preset threshold. If it exceeds or falls below the threshold, it will trigger an alarm or automatic rejection.

III. Technical features of checkweighers

1. High speed: The checkweigher has the ability of fast response and high-speed processing, and can complete the weighing process of objects in a very short time, meeting the needs of high-speed transmission of objects on the production line.

2. High precision: The checkweigher uses high-precision sensors and data processing technology to ensure the accuracy and reliability of the weighing results. At the same time, the checkweigher can also perform automatic calibration and compensation to eliminate the influence of environmental factors on the weighing results.

3. Intelligence: Modern checkweighers usually have intelligent functions, such as automatic identification, automatic rejection, automatic statistics, etc. These functions can greatly improve the automation level of the production line and reduce the need for manual intervention.

4. Flexibility: Checkweighers can be flexibly configured and adjusted according to different production needs. For example, the appropriate sensor and parameter settings can be selected according to factors such as the shape, size and transmission speed of the object to ensure the accuracy and reliability of the weighing results.

5. Durability: Checkweighers are usually manufactured with high-quality materials and manufacturing processes to ensure that they have a long service life and stable performance. At the same time, checkweighers can also be regularly maintained and serviced to extend their service life and reduce the failure rate.

IV. Application of checkweighers in industrial production

Checkweighers are widely used in industrial production. For example, in the food industry, checkweighers can be used to detect whether the weight of food meets the standard; in the pharmaceutical industry, checkweighers can be used to detect whether the dosage of drugs is accurate; in the chemical industry, checkweighers can be used to detect the weight of raw materials and products, etc. These applications have greatly improved production efficiency and product quality, and reduced production costs and waste.
