Why Choose MQ-CVW3253S1
Weighing and Vision in One Machine
The conventional setup means buying a checkweigher and a vision inspection machine separately — two conveyor sections, two rejection systems. This machine integrates dynamic weighing and industrial-camera character inspection on a single L350×W230mm weighing platform. Weight data and vision verdicts are verified in parallel, and one rejection port intercepts both underweight and mis-coded products, freeing up an entire equipment position on your line.
Dynamic Accuracy from ±0.05g
Weighing range 1-1000g, dynamic accuracy ±0.05-0.3g, display resolution 0.01g. For small sachets with net contents of only a few grams, even a slightly short fill gets rejected; boxed, canned and bottled products up to a kilogram all fall within the same machine's range — no need for separate machines per pack size.
AI Character-Level Code Verification
An industrial camera with directional lighting first eliminates the glare and shadows typical of metal cans and metallized pouches before imaging; a deep-learning model reads production dates and batch numbers character by character, classifying blur, missing characters and wrong characters separately. It checks not whether something was printed, but whether every single character is correct — bad codes from clogged or ink-starved printer heads are rejected on the spot.
5-90 m/min to Match Any Line Speed
Belt speed is continuously adjustable from 5 to 90 m/min, connecting to anything from slow manual lines to high-speed filling lines. The machine stores 100 product recipes — at changeover, just recall the recipe and run, no re-teaching required. Suitable for products up to 200mm in both length and width; simply check your package dimensions when selecting.
Five Interfaces for Direct MES/ERP Integration
USB, RS485, RS232, Ethernet and WIFI data outputs come standard. Batch records and inspection logs can be exported and connected directly to MES/ERP systems. Every product's weight value and character verdict is archived — when a complaint comes in, pull the data by batch instead of digging through paper spot-check sheets.
304 Stainless Steel and Custom Rejection
The housing is 304 stainless steel — scrub-resistant and corrosion-proof, meeting the hygiene requirements of food and pharmaceutical workshops. Rejection mechanisms include air blast, pusher, swing arm, drop-out and flap types, customized to product weight and packaging form — air blast for light pouches so they don't tip over, pushers for rigid boxes for a clean, decisive reject.
Problems It Solves for You
Printer-head clogs and ink outages are sporadic. With manual patrols every half hour, mis-printed and unprinted products are already boxed and shipped in between — retailer inspection penalties and whole-batch returns cost far more than the machine itself.
AI vision reads the production date and batch number on every single product character by character, rejecting blurred, broken and wrong codes on the spot. Bad codes never leave this conveyor — no more relying on someone watching the printer.
Running checkweighing and vision inspection as two separate machines: the line needs two equipment positions, two screens, two sets of recipes, operators switching back and forth, and double the failure points and maintenance cost.
Weighing and vision are fused in one machine with parallel verification — one recipe and one rejection port handle both underweight and code defects, and installation takes only one 350mm weighing-platform section.
Small products of a few to a few dozen grams rely on manual spot weighing. Low sampling rates let underweight packs reach customers and trigger complaints; to play safe, you chronically overfill — giving away product every single day.
Piece-by-piece dynamic weighing across the full 1-1000g range at ±0.05-0.3g accuracy and 0.01g resolution. Underweights are rejected instantly, overweights are quantified — reclaiming years of habitual giveaway straight off your reports.
A customer complains that a batch has blurred dates or short weight. The factory digs through paper records but can't find per-unit data, responsibility can't be established, and the only option is a full recall at your own cost.
Batch records plus exportable inspection logs. Once connected to MES/ERP, every product's weight and character verdict is fully archived — pull the data by batch in minutes and settle responsibility with evidence.

Functions in Detail
Rejection Type Selected per Product
Multiple rejection structures are available — air blast, pusher, swing arm, drop-out and flap — all customizable. Selection is based on product weight, package rigidity and line layout: air blast for light few-gram sachets to avoid tipping and spillage, pusher or swing arm for rigid boxes and cans, drop-out or flap for irregular items. Rejection performance is validated with the customer's actual product samples before shipment.
How the Vision System Works
The industrial camera and directional light source are angled to suit the product surface. For highly reflective surfaces such as metallized pouches, glass bottles and metal cans, glare and shadows are eliminated before image capture while the character region is framed simultaneously. The deep-learning model verifies characters one by one, classifying blur, missing and wrong characters, with judgment thresholds tunable on site using customer samples.
Recipe Management and Changeover
The machine stores 100 product recipes — weight limits, belt speed and character templates are set once, and changeover means simply recalling the recipe, with no re-teaching. Weighing platform L350×W230mm, suitable for products up to 200mm long and 200mm wide, with a standard 3-section conveyor structure that docks to your existing lines at both ends.
Data Output and Traceability
USB, RS485, RS232, Ethernet and WIFI interfaces come standard. Inspection logs and batch records can be exported, and MES/ERP integration enables per-unit data upload. Optional add-ons include real-time printing, code-reading sortation, in-line coding, in-line code reading and in-line labeling, configured to your line's marking and sorting needs.
Construction, Material and Power
The housing is 304 stainless steel, standing up to daily scrubbing and sanitizing in food and pharmaceutical environments. Power is AC220V±10% single phase — plug into ordinary workshop power with no dedicated wiring. The belt structure is designed for easy daily cleaning, minimizing residue buildup and hidden contamination.
Industries & Application Scenarios
Code inspection on can bottoms for aluminum and glass cans. Reflective can surfaces are the main cause of missed defects; directional lighting eliminates glare so production dates are read can by can, wrong and broken codes rejected instantly while fill net content is verified in the same pass.
Carton serialization and batch-number verification. Traceability codes and batch numbers are read box by box with character-level print-quality judgment; combined with ±0.05-0.3g checkweighing to catch missing leaflets or blister cards, with inspection data archived to meet traceability requirements.
Label QR-code and expiry-date inspection on sachets, tubes and bottles, with fill weight controlled at the same time — the 1-1000g range covers most formats from trial size to full size.
Sachet-packed nuts, candy, tea and similar products from a few grams to several hundred grams: per-bag checkweighing prevents underweight complaints while printed dates on the bag face are verified simultaneously; belt speed adjusts up to 90 m/min to match the bagging machine's pace.
In-line inspection of production dates and batch numbers on cartons and pouches, with optional in-line labeling and code-reading sortation — completing dual sign-off on marking and weight before products leave the plant.
