Manufacturers packaging sachets, tubes, ointments, and other small-format products increasingly need cartoning equipment that can handle multiple box sizes without long changeover delays or accuracy compromises. This need spans pharmaceutical, chemical, electronics, and food production lines, where labor costs, inspection accuracy, and line coordination all affect output quality. Guangdong Rich Packing Machinery Co., Ltd., operating under the brand name Rich Packing, has engineered its RQ-ZH-120L Automatic Cartoning Machine to directly address these operational pressures.
Understanding the Multi Size Box Challenge in Cartoning
Packaging operations that rely on manual cartoning face several recurring difficulties. Manual labor drives up operating costs, while missed or misplaced products and leaflets introduce quality risks that can affect an entire production batch. In addition, when cartoning equipment cannot coordinate smoothly with upstream and downstream packaging machinery, continuous production is disrupted. These pain points are especially pronounced when a single line must accommodate varying carton dimensions, as is common with sachets, tubes, and other compact product formats used across chemical, food, and pharmaceutical sectors.
Rich Packing’s Answer: The RQ-ZH-120L Automatic Cartoning Machine
The RQ-ZH-120L is Guangdong Rich Packing Machinery Co., Ltd.’s automatic vertical cartoning machine, positioned for small and medium production volumes and built to operate within GMP-compliant environments. It integrates optical, electronic, pneumatic, and mechanical technologies into a single unit that completes the full cartoning sequence: feeding, carton forming, conveying, leaflet folding, inspection, product insertion, batch printing, tongue closing, carton sealing, and missing-product rejection.
One Machine, Multiple Formats
A defining characteristic of the RQ-ZH-120L is that one machine handles multiple product formats and specifications. This is reflected directly in its carton and leaflet handling ranges. The machine accommodates carton sizes from 65mm to 150mm in length, 35mm to 85mm in width, and 12mm to 45mm in height, with carton weight tolerances of 240 to 360 grams per square meter. Leaflets are supported across an open carton size range of 78mm to 250mm in length and 85mm to 170mm in width, with one to four folds and a weight range of 60 to 70 grams per square meter. This breadth of supported dimensions is what allows the same machine to serve product lines that require multi size boxes, rather than requiring separate equipment for each carton variant.
Dual Servo Feeding for Speed and Stability
The RQ-ZH-120L uses a feeding system with dual servo motors, which allows it to reach speeds of up to 125 cartons per minute, with an operating range of 35 to 125 cartons per minute. Rich Packing notes that this dual servo configuration is faster and more stable than a single-servo-motor setup, which matters for manufacturers running continuous, high-volume shifts.
Dual Inspection for Quality Assurance
To address the quality risks associated with missed or misplaced products and leaflets, the machine applies a dual inspection methodology. Products and leaflets are verified before insertion, and then verified again once inside the carton. This two-stage check is designed to catch incorrect quantities and improper carton placement, providing a more complete detection process than a single inspection point would allow.
Durable Construction for Long Service Life
The RQ-ZH-120L is built from stainless steel or nickel chrome-plated materials, chosen for their stable chemical properties, corrosion resistance, non-toxicity, and safety. Welded areas undergo tempering treatment to extend service life. The machine also incorporates a dual clutch design that activates bidirectional protection if the main motor becomes overloaded or the leaflet folder faults, safeguarding both the equipment and the operator.
Technical Specifications That Support Flexibility
Beyond carton and leaflet dimensions, the RQ-ZH-120L operates on a total power of 1.10 kW, with a power supply option of 220V or 380V at 50Hz. It requires air pressure of at least 0.6 MPa and consumes 120 to 160 liters of air per minute. The machine’s physical footprint measures 2,150mm by 1,140mm by 1,800mm, with a net weight of about 1,500 kg. Rich Packing states that the compact footprint, at approximately 3 square meters, eases both floor space planning and transport logistics for facilities working with limited installation area.
Intelligent Monitoring and Maintenance
The machine is described as having a high level of intelligence, achieved through dense inspection points positioned at leaflet feeding, leaflet counting, product loading, product counting, and carton positioning. This arrangement supports monitoring of the complete process rather than only the final result. Fault conditions and counting data are fully visualized and can be viewed on the touch screen at any time, which simplifies maintenance troubleshooting. All components are also clearly numbered, which Rich Packing positions as a convenience for routine maintenance work.
The machine’s electrical components come from established international brands, including Baker and Siemens, which Rich Packing states helps ensure reliable quality. The broader configuration list includes servo motors and drivers from Panasonic (Japan), a main motor from SEW (Germany), a frequency converter from Danfoss (Denmark), a PLC from Siemens (Germany), sensing components from Omron (Japan) and SICK (Germany), solenoid valves and vacuum components from SMC (Japan), and other parts sourced from manufacturers such as Kögel (Germany) and Schneider (France). Rich Packing indicates this configuration supports stable operation suitable for continuous 24-hour production.
Integration Into Coordinated Production Lines
One of the recurring pain points in packaging operations is the difficulty of coordinating cartoning with upstream and downstream equipment. The RQ-ZH-120L is designed to be highly integrated, connecting with end sealers, blister packaging machines, counting and bottling lines, cellophane overwrapping machines, strapping machines, and other cartoning machines according to production requirements. This allows the machine to function either as a standalone unit or as part of a coordinated line, reducing the disruption that can occur when packaging steps are not synchronized.
Industry Applications
Rich Packing positions the RQ-ZH-120L across four primary industries. In pharmaceutical production, it supports GMP-compliant cartoning for blister packs, bottles, and tubes. In chemical production, it handles cartoning of tubes, ointments, and sachets. In electronics, it is adapted for cartoning electronic cigarettes and related items. In food production, it manages sachets and comparable packaged products. Across all four sectors, the shared requirement is a machine that can move between formats without sacrificing inspection accuracy or throughput.
For manufacturers evaluating cartoning equipment that must serve multi size boxes across sachets, tubes, and small cartons, the RQ-ZH-120L from Guangdong Rich Packing Machinery Co., Ltd. offers a documented combination of format flexibility, dual servo speed, dual-stage inspection, and line-level integration.
