Roller Checkweigher for Heavy-Duty Products in Carton or Bag Packaging
These are our customized roller checkweighers for a chemical industry client,can be installed at the end of the production line.Its core advantages include:
Photoelectric Sensor: Ensures precise product positioning.
Retaining Baffle: Prevents accidental drops due to motion inertia.
Modular Design: The display and control unit is separated from the weighing platform, making it simple to use and ideal for applications where the control area is located away from the production line.
Robotic Arm Integration: Customizable to integrate with robotic arms as required. After weighing, real-time signals are sent to the control system, which directs robotic arms to sort rejects to the defect area and approved products to the palletizing zone.
Special Design: The frame is coated with grey powder, and the control box is coated with white. A large LCD screen is provided for intuitive operation.

Roller checkweigher are widely used in industries such as food, pharmaceuticals, daily chemicals, and electronic products.
