Tube scale is a weighing equipment designed for flexible hoses and strip-shaped items. It is mainly used to check whether the weight of these products meets the standards and to remove unqualified products to ensure quality.
The strip scale completes signal acquisition through a weighing conveyor and transmits the weight signal to the controller for processing. When the product to be tested enters the weighing conveyor, the system identifies the product entering the weighing area based on the photoelectric switch signal or internal level signal. The system determines the departure time of the product based on the speed, length, or level signal of the conveyor. The weighing sensor transmits the detected weight signal to the controller, and the controller selects the signal in the stable signal area for processing to obtain the product weight.
Function:
By using a weighing sensor to detect the weight of the product, the controller compares it with preset standards to determine whether it is qualified. Unqualified products will be automatically removed. Suitable for various fields such as food (such as long packaged food), chemical raw materials (such as industrial strip products), etc.
Key components and functions
Conveyor: responsible for transporting the tested products to the weighing area and completing the transportation and positioning of the products. The form of the conveyor can be selected according to the shape and size of the conveyed object, such as belt, chain, and roller conveyor.
Weighing sensor: used to detect the weight of products and convert the weight signal into an electrical signal for transmission and processing. Resistance strain sensors have become an important choice due to their wide range of applications.
Controller: Receive the weight signal transmitted by the weighing sensor, process and analyze it to obtain the product weight value. The controller can also compare weight data with preset values to determine whether the product is qualified and issue control signals.
Removal device: According to the controller instructions, unqualified products are removed from the production line to ensure the normal operation of the production line and stable product quality.
Advantages:
High precision detection: high-precision components such as resistance strain sensors are used to ensure the accuracy of weight detection.
Efficient operation: Automated process design enables rapid completion of the entire process from entering the weighing platform to leaving, meeting the needs of large-scale production.
Wide applicability: It can detect various forms of products such as hoses, strips, and pellets, and supports docking with sealing machines, pellet making machines, and other equipment to form an automated production line.
