- ✓Saves floor space effectively by consolidating re-inspection from multiple converging lines
Why Choose MQ-DZ07
Three rejectors integrated in one machine
Pusher, swing-arm and air-jet rejection mechanisms are all built into a single unit, so boxes, bottles and cans, and light small bags each have a matching rejection method. Changing products requires no retrofit, and you save the cost of buying separate rejection units for each package format.
One machine handles recheck for multiple lines
Purpose-built for downstream packaging lines where several lines converge: products from multiple packaging lines merge onto this single checkweigher for weight rechecking and reject of defects. No need to fit a checkweigher at the end of every line — the equipment investment is spread directly across the number of lines.
Reject and divert without jamming the line
Conforming products pass along the main line, while out-of-tolerance products are moved off the main flow by the selected rejection method and collected separately. The pile-ups and mixing common at convergence points are handled inline by the machine, without workers sorting by hand beside the conveyor.
One recheck point saves floor space
Fitting each line with its own checkweigher means every unit takes up a stretch of conveyor and operating space; sharing one machine after convergence keeps only a single recheck station in the workshop. The space saved can go to packaging machines or buffer conveyors — especially practical for retrofitting older plants.
Universal across food, pharma and daily-use lines
Developed for downstream packaging lines in the food, pharmaceutical and daily-use industries. Common package formats — bags, bottles, boxes, cartons — can all find a suitable method among pusher, swing-arm and air-jet, so one machine covers the recheck needs of multiple product categories in the workshop.
Source factory, customized to your line
This is a custom model: the number of converging lines, conveyor height and reject-outlet orientation are all designed to your on-site layout. As a checkweigher source factory, Miqi has its own engineers handling surveying, manufacturing and installation, so it integrates into your existing conveyor line right on delivery.
Problems It Solves for You
The workshop has three or four packaging lines, and every line end needs its own checkweigher. Equipment investment multiplies, and an old plant's line ends simply can't squeeze in that many inspection stations and operating space.
After the lines converge, a single MQ-DZ07 handles rechecking and rejection. One purchase, one recheck station — equipment and floor-space costs are spread across the number of converged lines.
The same line runs light small bags today and bottled or boxed goods tomorrow. A single pusher rejector easily knocks light packages flying or spills them, while an air jet can't shift heavy items — every product change means stopping the line to swap rejection parts.
This machine carries pusher, swing-arm and air-jet rejectors at once, so you select the matching method by package format. Product changes need no rejection-mechanism swap, cutting line-stop time.
Manual spot-checks guard the convergence point, and products with missing or under-filled parts slip through into the market. A single customer complaint or a failed spot-inspection penalty can wipe out months of quality-control spending.
After convergence, every product is weighed and rechecked one by one, and out-of-tolerance items are rejected and diverted on the spot. The risk of missed spot-checks is stopped at the end of the packaging line, and defects don't leave the workshop.
Rejected defects and good products pile up together at the convergence point, requiring a second round of manual sorting. The higher the output, the messier it gets, and rework verification eats up a lot of labor.
Rejection and diversion are completed in one step: defects are moved off the main line along a set path and collected separately, while good products go straight into cartoning. The machine keeps order at the convergence point.
Functions in Detail
The three rejection methods explained
The pusher type has a forceful stroke, suited to boxed and bottled packages with some self-weight; the swing-arm type paddles products continuously off the main line, suited to medium-speed rejection of bottles, cans and boxes; the air-jet type is contactless rejection, suited to light small-bag products, avoiding mechanical impact that could burst packs or spill contents. All three are integrated in one machine, selected by product format.
Multi-line convergence and diversion logic
Products from multiple upstream packaging lines merge into this machine, are dynamically weighed one by one and judged on the spot: good products pass along the main line into cartoning, while out-of-tolerance items are moved off the main flow by the selected rejector and diverted for collection. Rechecking shifts from multiple scattered points to a single concentrated one, making the quality gate at the line end clearer and easier to manage.
Sharing floor space and recheck workload
Converged rechecking turns one-scale-per-line into one-scale-for-many-lines, saving not only the number of machines purchased but also the conveyor transition sections and operating/maintenance space each scale requires. With recheck volume concentrated on one machine, daily calibration, inspection and record-keeping are concentrated too, so quality management goes from many-headed to single-headed.
Customized to fit your on-site line
This is a custom model: the number of converging lines, conveyor height and direction, reject-outlet orientation and defect-collection method are all designed to your workshop's actual layout. As a source factory, Miqi handles on-site surveying, solution selection, manufacturing and installation with its own engineers, and bears the cost of matching to your existing conveyor line.
Industries & Application Scenarios
After several vertical packaging machines discharge and merge, snacks such as chips and candy share this machine to recheck for missing or under-filled packs. Air-jet rejection puts no mechanical impact on light small bags, so rejected items stay intact and can be recovered and repacked.
Multiple flow-wrap lines for bread and cakes converge downstream; each item is weighed and products missing parts or off-weight are rejected. The swing-arm method gently paddles boxed and tray-packed products off the main line, avoiding damage to soft products.
Multiple lines of blister-in-carton and bottled medicine converge downstream; each item is weighed to detect off-weight cartons missing a blister or a leaflet and reject them immediately, meeting pharma requirements for packaging-integrity rechecking.
Multi-format products such as toothpaste, soap and wash-care samples converge on the downstream packaging line. The three rejection methods cover formats from light small bags to bottles, so one machine guards the weight gate across multiple categories.
Small sauce pouches and compound seasonings converge for rechecking after multi-line packaging; products missing packs or short on material are rejected by pusher or air jet, avoiding the waste of discovering shortages only after full-case cartoning and having to unpack for rework.
