Two things decide the model, and speed is only the second one.
What you pack comes first. Blisters, bottles and sachets each need a different feeder at the infeed. In the 120 series that is three separate machines. Above 120 the machines are more general, except the 260P, which is built for bottles.
Carton size is almost the same across the range. Every model takes a carton 70 to 180 mm long. Only the width narrows slightly above 180 cartons a minute, from 85 to 80 mm. So you do not lose carton flexibility by buying speed.
Industry Applications
The WZH-320 is specifically designed for mega-factories requiring non-stop, maximum daily throughput:
Changeover
Throughput sells machines. Changeover decides what you actually produce in a week.
What changed | What you adjust | Roughly |
Same carton, new batch | Recipe on the screen | 15-30minutes |
Carton length or width | Handwheels only — no parts to change | 15-30minutes |
Carton or product height | The pusher head and pusher block must be swapped | 15-30minutes |
Product format changes | The feeder at the infeed | 15-30minutes |
Closing style (tuck-in → glue) | Not a changeover. That is a rebuild | — |
Length and width are a handwheel. Height means changing the pusher. A different product means a different feeder. A different closing style means a different machine.
What to check before you buy
The five questions any supplier should ask you
What goes in the carton and how many. Carton dimensions and closing style. Leaflet format and whether it arrives folded. What feeds the machine upstream. Target speed. If a supplier quotes you without these, the machine that arrives will not fit the line it was bought for.
Carton sizing — where most projects go wrong
Manually packed cartons are usually a snug fit around the product. An automated pusher needs clearance. Send us both your product and carton dimensions. We will tell you before you order whether your existing carton runs, or needs modifying — rather than after it has been printed in quantity.
The documentation
Operating and maintenance manuals in English, electrical schematics, a spare parts list with part numbers and prices, and a signed FAT report before the machine ships. Ask any supplier to show you a sample manual page before you order.
Why buy from us
One point of contact — You deal with us for the machine, the installation and the service call. Custom feeders, closing configurations and layout changes go through the engineers who build it.
Installation and training — We install it, commission it, and teach your operators.
Spare parts — Wear parts listed and priced in your quote before you sign.
Lead time — About 1-3 months. European suppliers quote 18 to 24.
WZH-320 Cartoning Machine FAQ
At this extreme speed, traditional vertical or linear suction systems cannot overcome air resistance and cardboard stiffness. The WZH-320 overcomes this challenge by deploying an advanced 4-station rotary star-wheel outward opening system paired with an active twice-pre-forming device. This continuous rotary action forces the carton scores to break and shapes the box perfectly square while in fluid motion, completely eliminating structural failures or crushed cartons.
The automatic leaflet folding and feeding unit is mechanically linked and electronically synchronized with the main conveyor drive. It utilizes high-speed “holding finger” clamping technology. As the posterior tracking pusher moves forward, the leaflet and the product are locked together and guided into the carton concurrently during parallel motion, ensuring zero displacement or folding damage even at 320 cycles per minute.
Yes, absolutely. The machine is equipped with an intelligent, highly adaptable feeding magazine. The electronic counting parameters and product collection cycles can be adjusted and set randomly via the HMI touch screen, enabling the system to smoothly stack and insert multi-count blisters (e.g., 2, 3, or 4 plates per box) into the moving cartons without dropping speed.
Missing a single item at 320 bpm can cause immediate downstream line jams. The WZH-320 utilizes a continuous optical tracking loop. If the upstream sensor detects an empty station in the feed conveyor (missing blister, bottle, or sachet), the PLC commands the vacuum valve to bypass that specific cycle. The machine will not draw a carton or feed a leaflet for that cycle, saving packaging materials and preventing empty boxes from entering your final shipper cases.
The machine features a multi-layered automatic mechanical and electronic overload protection shutdown framework. High-sensitivity torque sensors monitor the main drive, tracking pushers, and carton chains. If any abnormal resistance or collision is detected, the system cuts power to the drive within milliseconds, triggers an audio-visual alarm, and pinpoints the exact trouble location on the HMI to secure your capital investment.
Despite being a massive 2500 kg industrial platform, it features a highly streamlined design focused on operational convenience. All primary 3D adjustments are equipped with mechanical hand-wheels, digital scale indicators, and quick-release locking levers. A trained operator can execute a complete format swap (length, width, and height adjustments) efficiently in 20 to 30 minutes without requiring complex specialized tools.
Yes. The WZH-320 is fully ready for modern pharmaceutical infrastructure. The integrated industrial PLC system supports seamless data communication protocols for MES (Manufacturing Execution Systems) and SCADA networks. It tracks real-time batch counts, rejection rates, downtime reasons, and total OEE analytics, providing the transparency needed to comply with strict global data tracking audits and global GMP management standards.
