Medium Checkweigher for Production Lines
This medium checkweigher machine is used for continuous weight inspection during production. It checks whether each product or package meets the required weight standard, verifies net content, detects missing items or incomplete packages, and helps remove underweight or overweight products from the line. Compared with manual weighing, it improves inspection efficiency, reduces labor cost and helps ensure consistent product quality before delivery.
High Precision and Stable Performance
The machine uses high-precision sensors and reliable core components, combined with a three-section conveyor structure and adjustable conveying speed. The stainless steel frame is corrosion-resistant, durable and suitable for long-term production use. Adjustable feet and movable casters make it easy to match different production line layouts.
Color Touch Screen and Easy Operation
The checkweigher is equipped with a 7-inch or 10-inch color touch screen. The interface is simple and easy to operate, with automatic product learning, product parameter storage, real-time production monitoring, data recording and report export functions. Operators can quickly set up and manage daily production.
Standard and Customized Checkweigher Models
We provide automatic checkweigher models for small, medium, large and heavy products. They can be used for bags, boxes, cartons, cans, bottles, tubes and other packaged products in food, pharmaceutical, cosmetic, daily chemical and industrial applications. Machine size, weighing range, accuracy, speed and rejection method can be customized according to your product.
Alarm and Rejection System
The machine can be equipped with sound and light alarms, as well as different rejection systems such as air blast, pusher, lever rejector, flap rejector, slide, collection bin or customized rejecting devices. With photoelectric sensors, the system can accurately identify and reject underweight, overweight, empty or incomplete packages.
Checkweigher with Metal Detector
A checkweigher and metal detector combination system integrates weight inspection and metal contaminant detection in one compact machine. It helps control product weight and detect metal foreign objects at the same time, while reducing installation space compared with two separate machines.
Single-Belt, Roller Conveyor and Custom Checkweigher Solutions
For slow-speed products that do not require automatic rejection, we can provide single-belt checkweighers. For production lines using roller conveyors, roller checkweigher solutions are also available. The system can also be integrated with vision inspection, X-ray inspection, labeling machines, inkjet printers and other production line equipment.
Weight Sorting and Grading Options
With additional sorting and rejecting devices, the checkweigher can also be used as a weight sorting machine or weight grading scale. It can sort products by different weight ranges and is suitable for seafood, aquatic products, agricultural products, meat products and industrial parts.
