Why Choose MQ-CW6040L5
±0.5g accuracy catches missing pages
Checkweighing accuracy of ±0.5-3g with 0.1g display resolution. A book missing one signature, a leaflet left out, a calendar short one page — the weight difference is usually just a few grams, well within this machine's resolving power. 100% inline inspection replaces manual spot checks, and defective units are rejected on line before they ever reach packing.
1g to 5kg: one machine covers your whole line
With a checkweighing range of 1-5000g, everything fits — from single-page insert cards weighing a few grams and 100g snack pouches to multi-kilogram hardcover books and stacked calendars. Two weighing segments come standard (three optional), so light and heavy products weigh in their own zones and you never buy a second machine for a different SKU.
400mm-wide lane — even landscape books pass through
Handles products up to 400mm wide and 300mm long, so large-format art books, wall calendars and wide flexible bags travel through sideways without snagging. The housing is 304 stainless steel — it resists corrosion in dusty, paper-lint workshop conditions and wipes clean in seconds.
5-90 m/min variable speed keeps pace with post-press lines
A variable-frequency drive motor adjusts belt speed anywhere from 5 to 90 m/min. Placed downstream of a gathering machine, cartoner or vertical form-fill-seal packer, it matches the upstream cycle rate — no backups, no gaps, and never the bottleneck in an integrated line.
100 product recipes — changeovers without re-tuning
Store up to 100 product recipes on board. Switching book formats or snack weights takes one recall on the touchscreen — no resetting limits or belt speed every time. Three-level user permissions with custom passwords mean operators can run the machine but not alter it, so parameters stay exactly where your technicians set them.
Four rejection methods — chosen to protect your product
Pusher, swing arm, drop-flap and up-down flap rejectors are configured to your product: pushers for rigid books, swing arms for crush-sensitive soft bags, drop-flaps for thin sheet products. The reject action matches the product, removing defects cleanly without damaging appearance.
Problems It Solves for You
Print shops occasionally gather or sew books with missing or duplicate signatures. Manual flip-through spot checks miss some, defective books reach readers, and publishers claim contract damages or return entire batches for rework.
±0.5-3g checkweighing accuracy inspects every single book; the weight difference of one missing signature is detected in real time and the pusher rejects it on line — defects never leave the workshop.
Snack pouch filling occasionally produces short-fill or empty bags. E-commerce platforms fine sellers for underweight complaints and store ratings drop — spot-check scales simply cannot plug the leak.
Dynamic weighing of every bag across the 1-5000g range, with underweight bags auto-rejected. Optional real-time printing and USB data export keep checkweighing records for every batch, so you answer complaints with data.
Desk calendars and gift boxes have many components (base, inner pages, insert cards). Seasonal temp workers miss parts during peak assembly, and customers open boxes to missing items and leave bad reviews.
Full inspection against the standard product weight: one missing base or a few missing pages triggers rejection immediately, intercepting incomplete sets before boxing.
High-mix, small-batch orders mean constant changeovers. Each setup takes half an hour or more, and on tight deadlines machine adjustment eats more time than production itself.
One-touch recall of any of 100 recipes — switch products on the touchscreen and inspect immediately. The variable-frequency motor tracks upstream pace across 5-90 m/min, so you change orders, not machines, with minimal downtime.

Functions in Detail
Rejection Methods & Customization
Standard options include pusher, swing arm, drop-flap and up-down flap rejectors, selected by product rigidity, weight and conveying orientation — or fully customized to your line layout. Air supply requirement is 0.5-0.8MPa, compatible with standard workshop air lines; reject port position and collection bin format adapt to site conditions.
Data Management & Traceability
Checkweighing results export via USB, with batch pass rates and reject counts at a glance. Optional real-time printing issues inspection records right on the line. For customer audits or short-weight complaints, pull the batch data and you have documented proof — full quality traceability.
Optional Function Modules
Beyond checkweighing, add barcode-reading sortation, inline coding, inline scanning and inline labeling modules — completing weighing, coding, labeling and sorting in a single lane, reducing standalone equipment count and floor space on your line.
Safety Protection Design
The system includes hazard alerts, an emergency stop button and safety guards, with physical isolation around the rejection zone, so even temporary workers are unlikely to be injured by accidental contact. Three-level permissions with custom passwords give administrators, technicians and operators separate interfaces, keeping parameter changes under control.
Line Integration Capability
The variable-frequency motor provides continuously adjustable speed from 5-90 m/min, integrating with automatic cartoners, production conveyors, filling machines and vertical packers. Infeed and outfeed heights are customized to your adjacent equipment — it connects to the line on delivery, with no extra transfer conveyor needed.
Industries & Application Scenarios
Installed downstream of gathering machines and perfect-binding lines, it checkweighs every book and magazine, detecting missing or duplicate signatures and omitted inserts, and rejects defects before boxing — preventing full-batch returns.
Chips, nuts and other flexible pouches are weighed bag by bag as they exit the vertical packer; under- and overweight bags are auto-rejected, and the swing-arm rejector removes inflated bags without crushing them — eliminating short-weight complaints.
On desk calendar, wall calendar and notebook gift-set assembly lines, it verifies that bases, inner pages and bonus cards are all present; the 400mm-wide lane lets large-format products pass through in landscape orientation.
Packed book and gift orders get a final full-package weight check; a missing freebie or wrong-SKU shipment triggers an alarm and rejection on the spot, cutting returns, exchanges and negative reviews from mis-shipments.
Manuals and certificates for appliances, pharmaceuticals and medical devices are checkweighed in stacks or in the box; even a single missing sheet of a few grams shows up at 0.1g display resolution, ensuring complete documentation leaves the factory.
