Online belt weighing machine for bags/boxes below 3000g

Heavy-duty precision: ±0.5g accuracy for ≤3kg products (up to 300x290mm). 80ppm speed with gentle pusher/pendulum rejection. Full SUS304 hygienic design + 7″ HMI. Self-learning (2K recipes), MODBUS/RS-232 I/O & Habasit belt. Built for cosmetics/detergents.

  1. Robust Handling for Large Items
    • 3kg capacity​ (±0.5g accuracy) with oversized ​300×290mm platform—ideal for shampoo bottles, detergent boxes, or cosmetic gift sets.
    • Habasit conveyor belt​ (932×300mm) ensures stable transport for irregular packaging.
  2. Gentle Rejection for Sensitive Products
    • Pusher/pendulum rejection​ prevents damage to fragile items (glass bottles, luxury cosmetics).
    • 120W 3-phase motors​ + ​Siemens V20 inverter​ enable adjustable speed (30–90m/min) for delicate handling.
  3. Hygienic & Compliant Design
    • Full ​SUS304 stainless steel construction​ (resists chemical corrosion from cleaners/cosmetics).
    • Easy-disassembly conveyor for deep cleaning—critical for GMP compliance in pharma/cosmetics.
  4. Plug-and-Play Intelligence
    • Self-learning function​ + ​2,000 recipe storage—seamlessly switch between SKUs (e.g., shampoo → toothpaste → shoe polish).
    • Chinese Unicode support​ for local labeling and intuitive recipe names.
  5. Factory-Floor Toughness
    • Auto fault diagnosis​ (motor/sensor/pneumatics) minimizes downtime.
    • MODBUS/RS-232 communication​ integrates with printers/PackML systems for traceability.

Description

belt weighing machine Scope of application:

This product is suitable for testing the weight of individual products. It is widely used in many industries such as electronics, pharmaceuticals, food, beverages, health products, daily chemicals, light industry, agricultural and sideline products. Such as cosmetics for daily chemical products (including cosmetics, cleaning, cosmetics, skin care products, hair cosmetics, etc.); detergents (including soaps, washing powder, detergents, etc.); oral products (including toothpaste, mouthwash, etc.); Other chemical products (including shoe polish, floor wax, deodorant, insect repellent, etc.).

belt weighing machine Product Features:

 Strong versatility: the standardization structure of the whole machine and the standardized man-machine interface can complete the weighing of various materials;

 Simple operation: Fully intelligent and user-friendly design using Weilun color human-machine interface; conveyor belt is easy to disassemble, easy to install and maintain, easy to clean;

 Adjustable speed: use variable frequency control motor, the speed can be adjusted as needed;

 High speed and high precision: high precision digital sensor, fast sampling speed and high precision;

 Zero tracking: can be manually or automatically cleared, and dynamic zero tracking;

 Report function: built-in report statistics, the report can generate EXCEL format, can automatically generate a variety of real-time data reports,

External USB interface, can insert U disk to export data in real time, hold the production status at any time; provide factory parameter setting recovery function, and

Store a variety of recipes, easy to replace product specifications;

 Interface function: reserved standard interface, convenient data management, and communication with PC and other intelligent devices;

 Self-learning: After setting the product recipe information, you do not need to set the parameters. The self-learning function automatically sets the device suitable parameters and saves them when you switch products next time. (The parameter storage entry is 2000, which can be increased).

 Operating mode: three operating modes

  1. Dynamic mode: normal pipeline mode; 2121
  2. Static mode: After the material enters the weighing platform, the weighing platform stops running, and the weighing is performed to improve the accuracy, which is suitable for products with less than 20 passes per minute;
  3. Energy-saving mode: (optional) The energy-saving mode can be turned on on the basis of a and b modes, and no material is set to pass the shutdown time. When the equipment is idling, it will automatically stop after the long time, and then automatically start when there is material passing.

 Self-test of fault: It can detect by itself: whether the motor, inverter, AD, sensor and photoelectric are normal and the cause of the fault and the guidance detection of the cylinder, solid state relay and solenoid valve. Convenient for non-professional inspection and maintenance.

 Peripheral device communication: standard RS-485 and RS-232 dual communication port output.

  1. RS-485 interface is MODBUS, RTU standard protocol but can modify the write address (57600bps, 8, N, 1, slave station number 3) can not be modified.
  2. (Optional) The RS-232 interface is a custom protocol, and you can set the command to send the content yourself. (57600bps, 8, N, 1) can be modified.

 An external printer or printer can communicate with the device, or it can be connected with the front and rear packaging machines and production equipment to feedback the weighing result so that the recipe parameters can be automatically modified.

 Chinese input method

  1. The formula name can be entered in Chinese, and it is more intuitive to find the switching recipe.
  2. belt weighing machine With the RS-232 communication port, it is possible to send Chinese characters of Unicode strings to peripheral devices. (It is suitable for external printers or marking machines to print Chinese characters).
