1. Before purchasing a checkweighing system, you should first carefully consider the operating environment and the characteristics of your product. Factors such as humidity, temperature changes, dryness, excessive vibration, and airborne dust can negatively affect weighing accuracy. If the operating conditions are poor, with high humidity and dust content in the air, moisture and dust can enter and damage the mechanical parts of the conveyor belt and weighing sensors, thereby shortening the machine's service life. To eliminate the impact of a humid and dusty operating environment, you should look for special checkweighing technologies, such as those with sealed housings made from a single piece of plastic or metal. This can prevent dust and moisture from entering, protecting the internal precision weighing sensors and conveyor system drive motors from damage and premature aging. Remember to remind employees not to cause unnecessary movement or vibration around the automatic checkweigher, such as vibrations caused by an employee quickly passing by. Even very small vibrations or airflows can be detected by the sensitive checkweighing machinery, leading to measurement deviations. The above preventive measures can help avoid accuracy issues and prevent damage.

2. There is no one-size-fits-all checkweighing solution. Every production line is different, and the specific conditions of your equipment determine the specifications required for the automatic checkweigher. Before making a purchase decision, you need to carefully evaluate the various features and specifications of the automatic checkweigher to ensure the model is truly suitable for your production line. Before making such an investment decision, consider factors such as the product's weight and characteristics, packaging type, and the position of the automatic checkweigher on the production line.

Your product determines whether the conveyor system needs additional functions to ensure the packaging orientation, spacing, and stability are correct before reaching the automatic checkweigher. Packaging form, height, weight; whether the product is solid, powder, or liquid; packaging stability—all these factors affect weighing accuracy. Installing synchronous belts, screws, or wheel devices may help ensure the correct spacing of each package, guaranteeing that only one package passes the weighing sensor at a time. Side clamping belts and transfer devices can also be installed to ensure packaging stability. This optimizes weighing accuracy and allows for the correct rejection of non-compliant packages. For example, a soft drink bottle, due to its high center of gravity, may sway slightly on the conveyor belt, affecting the side-face accuracy of the automatic checkweigher. Installing side clamping belts near the weighing sensor can eliminate such swaying, ensuring the bottle remains as stable as possible during weighing.

The product also determines the type of rejection device used to remove packages from the production line. Smaller sealed packages can be rejected using simple air jet devices, while open containers may require blow-off type rejection equipment. Granular foods such as salt, flour, or sugar can damage the conveyor system, both through corrosion and by particles entering the conveyor machinery. This can cause unnecessary friction and damage to transmission components, leading to premature replacement of the conveyor system. If your production line falls into this category, be sure to choose an automatic checkweigher with a conveyor designed specifically for powder products. Such conveyors have wider belts with very small openings through which powder can enter the machinery. This reduces maintenance needs and ensures optimal weighing accuracy of the sensors. The automatic checkweigher must also be able to provide the highest weighing accuracy at the production line's required speed. This prevents reductions in output and production efficiency and minimizes the need for additional timed conveyor belts.
