Why Choose MQ-CW10070L80
Wide 1-80kg Case Range
A 1-80kg checkweighing range covers everything from small multi-kilogram cartons to full heavy cases on one machine. The 1000×700mm weighing section passes boxes up to 700×700mm, so rice bags, full beverage cases and bulk household goods run straight on the line — no separate scale needed for heavy cases.
±10-30g Dynamic Accuracy
Overall checkweighing accuracy of ±10-30g with 0.001kg display resolution. In real production terms: one missing 30g+ inner sachet, one missing bottle, or an omitted manual and free gift is judged the instant the case crosses the scale — no opening boxes to count.
5-90 m/min Variable Speed
Belt speed is continuously adjustable from 5-90 m/min. Slow it to 5 m/min behind a manual packing line for stable weighing, or keep pace at the tail of an automated packaging line. Speed is set at installation against the measured upstream and downstream conveyors — accuracy is never sacrificed to force throughput.
100 Recipes, Zero Re-Setup
The machine stores 100 product recipes; target weight, tolerance limits and belt speed for each SKU are set once and saved. On changeover, simply recall the recipe number and start the line — no trial weighing or re-entering parameters, which closes the door on a mis-set limit misjudging an entire batch.
USB Data Export for Traceability
Weighing data exports via USB — pass counts, reject counts and weight records for every shift and batch can be copied straight to archive. When a customer audit or shipping dispute calls for weight records, you hand over original machine data, not paper spot-check sheets written up after the fact.
Standard Utilities, Plug and Play
A Φ8mm air port is reserved for the rejector, working pressure 0.5-0.8MPa — connect straight to existing shop air. Power is AC220V±10%, ordinary single-phase. Painted carbon steel frame with standard left-in, right-out conveying, so it slots into your existing line with minimal modification.
Problems It Solves for You
Case packing is manual, and a missing inner bag, bottle or accessory only surfaces when the customer's warehouse counts the goods — deductions, returns, even full-pallet rework, with freight losses often exceeding the value of the goods.
Every sealed case is weighed 100%; ±10-30g accuracy is enough to detect a missing item inside the case, and the pneumatic rejector pushes out-of-tolerance cases off the line on the spot — problem cases never leave the workshop.
Heavy-case spot checks mean workers lifting 20-30kg boxes onto a platform scale hundreds of times a day. Sampling rates fall to a few percent, missed defects become routine, and when a complaint arrives there is no way to trace which batch it came from.
1-80kg in-line dynamic weighing — cases are weighed on the belt without being lifted off or stopping the line, achieving 100% inspection and freeing workers entirely from lift-and-weigh work.
Frequent changeovers across many SKUs mean operators reset target weights and limits from memory; one mistake misjudges an entire batch — good cases rejected or bad cases released.
100 pre-stored recipes: on changeover the operator just recalls the recipe number. Parameters are set and stored centrally by process engineers, so limits are never keyed in manually on the floor.
Key accounts and factory audits demand shipment weight records, but paper spot-check sheets are scattered, impossible to reconstruct afterwards, and no complete ledger can be produced at the audit.
One-click USB export of full-line weighing data, archived by batch as original machine records — pull the files directly at audit time with a complete traceability chain.

Functions in Detail
Rejection Method & Pneumatics
A Φ8mm air port is reserved on the frame; connect 0.5-0.8MPa standard shop air to drive the rejector. Given the wide 1-80kg span, the rejection type is specified at the model-selection stage based on product weight, case format and line speed — heavy cases are pushed off firmly and stably, with no tipping or spilling on the line.
Recipe Management & Changeover
Stores 100 product recipes; target weight, pass limits and running speed for each SKU are set once and recalled indefinitely. Operators only select a recipe number at changeover, while parameter-setting rights can be reserved for process managers — mis-set limits on the floor are eliminated by process design.
Data Management & Traceability
Weighing results are logged case by case and exported via USB, including pass counts, reject counts and weight data per batch. Archive by shift or by order, and present original machine records directly at customer audits, factory inspections and net-content checks — no manual transcription.
Structure & Line Integration
Weighing section 1000×700mm, maximum product size 700×700mm, conveying direction left-in, right-out facing the machine. The painted carbon steel housing suits dry workshop environments; AC220V±10% single-phase power needs no dedicated electrical work, and integration into an existing conveyor line is quick.
Speed-Accuracy Matching
Belt speed is adjustable from 5-90 m/min; running speed is set at commissioning to match upstream and downstream equipment, and dynamic accuracy is then calibrated per recipe on that basis. The ±10-30g accuracy varies with weight band and speed, and every SKU is test-verified before handover — no inflated spec numbers.
Industries & Application Scenarios
Full cases of beverages and boxed snacks are weighed after the case sealer to verify bottle and bag counts inside; a case short even one unit is rejected, preventing pallet-level deductions when retailers count incoming goods.
10kg and 25kg rice and flour bags and full cases of cooking oil are checkweighed in-line as they come off production, replacing manual lift-and-weigh sampling; heavy bags get 100% inspection without touching the floor, with under- and overweight diverted on the spot.
End-of-line checkweighing for cased laundry liquid and powder; a missing bottle or omitted promotional gift shows up as a weight deviation and is judged at the scale, blocking short-shipment complaints during e-commerce peak seasons.
A checkweighing station after the packing bench verifies parcel weight against the order recipe, intercepting picking omissions and wrong items before dispatch — fewer replacement shipments and less freight loss.
Bagged putty powder, granular materials and drummed coatings are checkweighed before dispatch, backstopping occasional underfills from net-weight fillers and avoiding short-content penalties or customer claims.
Packed product sets are weight-verified after casing; missing accessory packs, screw bags or manuals are detected from case-weight deviation, eliminating missing-parts complaints on arrival and second shipments.
