SZH‑220 High‑Speed Automatic Cartoning Machine: Reliable GMP‑Compliant Servo‑Driven Cartoner for Secondary Packaging
SZH‑220 High‑Speed Automatic Cartoning Machine: Reliable GMP‑Compliant Servo‑Driven Cartoner for Secondary Packaging
Page note: This article is compiled based on the original SZH‑220 operation manual and real‑world machine commissioning experience from our in‑house packaging engineering team.
The SZH‑220 high‑speed cartoning machine is a multifunctional continuous‑motion cartoner built for pharmaceutical, food, medical device and daily‑necessity industries. Compliant with pharmaceutical GMP standards, this fully‑automatic cartoning equipment combines mechanical, electrical, optical and pneumatic control to complete the full secondary packaging workflow automatically: carton picking & opening, leaflet folding, product feeding, product insertion, flap folding, tuck‑in sealing and defective‑product rejection.
Engineered for both high‑volume single‑variety mass‑production and flexible small‑batch multi‑SKU manufacturing, the SZH‑220 cartoner delivers short mold‑change cycles and easy‑to‑execute commissioning. It reliably processes blister packs, Chinese‑medicine preparations, pillow‑pack goods, regular small‑size articles and medium‑small food items, serving as a versatile workhorse on modern packaging lines.
Typical Application Scenarios
This cartoning solution fits pharmaceutical blister packaging, sachet‑form medicine, traditional Chinese medicine preparations, small food pouches and disposable medical devices. It handles large‑volume continuous production runs as well as frequent‑changeover small‑batch orders for pharmaceutical secondary packaging solutions.

Main Functional Modules & Working Principle
The SZH‑220 cartoning machine includes multiple synchronised core sections: product orientation‑feeding mechanism, integrated leaflet‑folding unit, carton magazine, carton suction‑opening mechanism, multi‑group product‑pushing station, carton‑conveying chain, flap‑folding assembly, tuck‑in sealing unit and finished‑product discharge conveyor. All stations run in precise sync under full‑servo and PLC control.
Integrated Leaflet Folding System
The built‑in leaflet folder performs 1‑4 folds automatically. Triggered by detection signals from the product conveyor chain, suction nozzles pick single sheets from the leaflet magazine. Sheets are folded into target formats and transported to the carton‑waiting station.
Equipped with an overload‑clutch protection structure, the folder mechanically disengages from the main drive during paper jams to prevent component damage. Operators can adjust paper‑tray angle, suction‑nozzle timing, folding‑roller gaps and paper‑stop discs for different leaflet dimensions and folding styles including single‑fold, Z‑fold and letter‑fold.
Carton Magazine & Carton Opening Mechanism
The long‑capacity carton‑storage magazine holds 1200‑1500 cartons per loading, lowering manual refilling frequency for operators. Vacuum suction cups pick flat lock‑tab cartons and erect them onto the carton conveyor chain.
Multiple proximity sensors monitor carton presence. When no carton is detected in position, the pusher skips the insertion cycle and diverts products to the reject bin to avoid mis‑packaging.
Continuous Multi‑Pusher Insertion Station
Adopting continuous‑motion multi‑pusher design, independent pushers insert leaflets first and then blister‑pack products. This design effectively reduces friction resistance between leaflets and packaged goods.
Overload‑sensing hardware provides jam‑protection: when blockage occurs, the movable guide rail retracts, sends overload feedback signals and triggers an emergency machine stop to safeguard mechanical parts.
Carton Sealing & Defect‑Rejecting Unit
Side‑flap folding blades and four‑bar‑linkage tuck‑in sealing components finish automatic interlocking‑tab closure. A reject device installed on the outlet conveyor removes non‑qualified cartons identified by vision and photoelectric sensors. Detectable defects include missing leaflets, missing products, incompletely folded flaps and carton‑opening failures.
Multi‑Point Detection Sensors For Quality Assurance
The SZH‑220 high‑speed cartoner is fitted with dozens of photoelectric and proximity sensors across the full workflow to realise intelligent production monitoring:
- Blister in‑feed detection, high‑low level material monitoring
- Leaflet‑gripping detection and leaflet‑jam detection inside the folder
- Carton‑presence detection and low‑carton‑level warning
- Blister‑in‑carton and leaflet‑in‑carton verification
- Side‑flap folding completeness inspection
- Push‑rod overload sensing for anti‑jamming protection
- Optional barcode reading for leaflets and cartons for full‑batch traceability
All abnormal conditions trigger alarm prompts displayed on the HMI touch‑screen for fast troubleshooting.
Key Advantages of SZH‑220 Servo‑Driven Cartoning Machine
- GMP‑Compliant Construction: Stainless‑steel frame and easy‑to‑clean surfaces; machine surfaces can be disinfected with medical alcohol. Solvent‑based cleaners are forbidden for touch‑screen panels.
- Wide‑range Adaptability: Supports frequent product‑specification switching for pharmaceutical blisters, sachets, medical devices and food packages.
- Full‑servo Synchronous Control: Stable high‑speed operation ranging from 50‑200 cartons/min with low noise and low failure‑rate.
- Multi‑layer Safety Protection: Overload clutches for main drive, leaflet folder and pushing mechanism; emergency‑stop button; safety protective covers; mandatory ground‑wire installation requirement.
- User‑Friendly Adjustment: Hand‑wheels and fine‑tune knobs adjust carton‑chain width, magazine position, folding‑blade timing and sealing‑station offsets. Size change‑over between different carton specifications consumes minimal working time.
- Intelligent Fault Reminder: PLC‑HMI system stores alarm logs and guides operators during routine maintenance.
Suitability & Limitations
The SZH‑220 cartoner works best with machine‑fed pre‑creased lock‑tab cartons. Manual‑folded or irregular cartons will trigger frequent jamming. Actual stable throughput depends on carton quality, leaflet‑folding complexity and product dimension. Extra‑large or ultra‑thin cartons require on‑site mechanical fine‑tuning before mass‑production.
Installation, Operation & Maintenance Notes
Installation & Environment Requirement
- Transport: Use forklift or crane lifting via designated M16 lifting threaded holes on the machine base. Maintain correct machine‑base ground clearance following manual specifications.
- Placement: Indoor horizontal mounting with 12 mm rubber foot pads; anchor bolts are not required. Reliable ground‑wire connection is mandatory.
- Working environment: Ventilated workshop without flammable‑explosive hazards; ambient temperature ‑25℃~55℃; max relative humidity 80 % (@20℃).
Regular Maintenance Checklist
- Electrical cabinet cleaning & inspection: Every 3 months
- Cooling‑fan and aviation‑plug checking: Every month
- Foreign‑object cleaning inside machine and carton chain: Every working shift
- Before restart after long‑time shutdown: Inspect power‑distribution‑system insulation resistance (>1 MΩ).
Important safety tip: Cut off main power before mechanical inspection, maintenance or cleaning. Never place hands inside running protective covers during machine operation.
Frequently Asked Questions
Q1: What carton types does SZH‑220 cartoning machine require?
A: It works for machine‑fed lock‑tab cartons with pre‑creasing, pre‑folding. Manual‑folded non‑standard cartons will cause jamming. Carton size must stay within 65×30×15 mm ~ 220×120×60 mm.
Q2: What is the speed range of this high‑speed cartoner?
A: Adjustable speed 50‑200 cartons per minute. Real stable output depends on carton complexity, leaflet‑folding times and product characteristics.
Q3: Can the SZH‑220 machine fold multi‑fold pharmaceutical instruction leaflets?
A: Yes. The integrated leaflet folder supports 1‑4 folds including Z‑fold, letter‑fold and unequal‑size folding styles. Paper weight must be 55‑65 g/m² offset paper.
Q4: Does the cartoner support defective‑carton automatic rejection?
A: Yes. Sensors detect missing blisters, missing leaflets, bad flaps and reject non‑conforming cartons automatically without stopping the whole line.
Q5: What preventive maintenance work is needed for SZH‑220 cartoning machine?
A: Daily cleaning of conveyor chains and sensors; monthly inspection of aviation plugs and cooling fan; quarterly inspection of electrical cabinet. After long‑term shutdown, check insulation resistance before power‑on.
Q6: Can I integrate this cartoner with upstream blister packing machine?
A: Yes. Reserved mechanical and signal interfaces allow connection with blister machines, pillow packers and feeding conveyors to build complete automatic packaging production line.
