Author: Smartweigh–Multihead Weighter
The multihead weigher is what we often call the loss-in-weight feeder, which is a measurement and verification mechanical equipment for the transportation of solid fiber raw materials. On the one hand, the multihead weigher can transport tiny raw materials with fine particles below 5mm, and has the advantages of continuous and uniform transportation, adjustability and strong adaptability. Resin film powder, flour, starch and other industries. The multihead weigher controls the discharge screw or electric vibration machine according to the reduction rate of the material weight in the weighing hopper to achieve the purpose of quantitative feeding, that is, multihead weigher. When the material in the weighing hopper reaches the lower limit of the weighing position, the material is discharged. The screw machine fixes the discharge amount according to the speed at the time, and controls the material in the silo to quickly drop into the weighing hopper. When the material reaches the upper limit of the weighing, the material is stopped. Fast charging can shorten the feeding time and improve the weighing. Heavy accuracy and control precision.
The weight sensor is the core component of the multihead weigher, which converts the interaction force into the electronic device data signal. Weight sensors are divided into various basic concepts, including resistance judgment type, piezomagnetic type, capacitive sensor, etc., but they are fully considered in terms of accuracy, accuracy, rationalization, and ease of use. At present, many production and processing It is still the resistance judgment type induction switch. It often accounts for more than 90% of the weightless feeder.
In recent years, the characteristics of the resistance judgment type induction switch have been improved. With the development trend of the fully automatic automatic control system of industrial production to the intelligent system, the digital display weightless state feeder has also been designed, developed and applied in recent years. . By doing it, it immediately outputs the amount of information, which further improves the anti-interference ability in the transmission, and promotes the communication with the computer to be extremely convenient and fast. Due to the cancellation of the simulation enlargement and A/D conversion link in the in-vehicle instrument panel, the in-vehicle instrument panel can be displayed and controlled by the computer in a large and simple manner, and the weighing display can be omitted.
At present, there are about two types of such inductive switches: resistance judgment type data information weightless feeder and new digital display weightless feeder. Therefore, it is recommended to control the production and processing quality of the weightless feeder in the whole process of production and processing, and reduce the difficulties caused by mechanical equipment in production and processing.
