CQ Automatic Roll To Square Bottom Paper Bag Making Machine
Product Introduction
CQ Series adjustable roll-to-square bottom paper bag making machine has the advantages of high speed, high production efficiency, and a wide adjustment range. It is designed to manufacture square bottom paper bags from paper rolls in blank or printed form and can complete side gluing, tube forming, cutting, bottom impressing, bottom gluing, bottom forming, and final product output within one time. Controlled by a PLC system, equipped with a touch screen and servo motor for bag length control, this machine can produce a variety of specifications of paper bags. It is a piece of equipment for making paper bags for foodstuff or shopping bags.
Performance Characteristics
- Hydraulic lifting is adopted for raw material loading and unloading, and fully automatic tension control is used for unwinding.
- Equipped with Japanese YASKAWA servo drives.
- Edge correction system adopts the domestic ARISE brand.
- The paper tube former is integrated with a thumb cutting function located under the forming mold.
- Automatic stop function when no material is detected.
- The center paper clamping, drum clamps, and drum mechanical fingers all adopt a spider-type synchronous adjustment mechanical design, which greatly shortens the mold adjustment time during size changeover.
- German KEB servos paired with German SICK photoelectric sensors to precisely track printing substrates.
- Fitted with an automatic lubrication supply system and blockage alarm system.
Performance Characteristics
Against the global wave of plastic restriction policies, paper packaging is steadily replacing plastic packaging as an irresistible industry trend. Orders for food takeaway bags, supermarket kraft shopping bags, and gift square bottom paper bags keep surging. Numerous packaging factories are in pursuit of fully automatic bag-making equipment with stable performance and high production efficiency. Rooted in the packaging machinery industry, Wenzhou Chenqi Machinery specializes in R&D and manufacturing of packaging equipment. Drawing on years of expertise in paper bag machinery development, we have elaborately developed the CQ Serrated Square Bottom Paper Bag Machine. Featuring exclusive integrated serrated forming technology and a full set of intelligent servo control systems, the machine realizes fully automatic one-stop processing from roll paper to finished handle-free square bottom paper bags. It serves as a core flagship model for packaging manufacturers worldwide to expand production, upgrade workshops and undertake foreign trade orders.
The serrated forming technology stands out as the core advantage that differentiates the CQ model from conventional square bottom paper bag machines. Traditional flat glued bottom paper bags commonly suffer from stress cracking, uneven adhesion, and deformed bag shapes. In contrast, Chenqi’s exclusive serrated pressing structure delivers uniform and precise indentation points with firm bottom sealing. Finished bags feature an upright and neat shape with enhanced load-bearing capacity, fully complying with premium packaging standards for high-end brands in Europe, America, the Middle East, Southeast Asia, South America, and other regions. The finished products are widely applicable for bakery food, daily retail, apparel packaging, and more scenarios. This machine is compatible with all paper types, including 50g to 150g kraft paper, white cardboard, and recycled eco-friendly paper. The complete CQ series covers multiple specifications with quick adjustment available for bag length, bottom width, and side width to switch between various bag styles effortlessly, catering to flexible production requirements for small-batch custom orders as well as mass overseas bulk orders.
In terms of automation and productivity, this fully automatic square bottom paper bag machine is equipped with a proven PLC control system and complete servo drive assemblies, paired with high-precision photoelectric color mark tracking, automatic constant tension deviation correction, and a hydraulic automatic loading structure. The whole production process including feeding, paper conveying, cylinder laminating, bottom serrated folding, gluing & sealing, cutting, and counting, operates unattended. It runs at high speed and maintains stable operation during long-hour continuous work. Built-in safety protection includes automatic alarm and shutdown upon paper breakage, material jamming, and glue shortage. The touchscreen HMI is user-friendly with one-click parameter setting for machine adjustment, lowering operation difficulty and effectively cutting labor costs. The precise quantitative glue supply system intelligently adjusts glue dosage according to running speed to reduce glue consumption and material wastage, helping factories slash overall production costs in long-term operation.
The whole machine is manufactured in full compliance with export CE standards. The cast iron machine frame guarantees solid durability, while all core components adopt first-tier brand parts. Every unit undergoes prolonged full-load trial operation before delivery under strict quality inspection to support non-stop 24-hour factory production. As a local integrated manufacturing and trading enterprise, Wenzhou Chenqi Machinery provides comprehensive export supporting services for global buyers. We offer a one-year full machine warranty, permanent supply of original spare parts, along with remote technical support, on-site installation & commissioning, and operator training. Customized turnkey eco-friendly paper bag production line solutions can be tailored according to customers’ workshop layout and production targets. Our equipment has been exported to dozens of overseas countries all year round and earned consistent recognition from clients at home and abroad.
To seize the opportunities of eco-friendly packaging and capture the overseas paper bag market, a high-performance servo square bottom paper bag machine is indispensable. Balanced in production capacity, finished product quality, and equipment durability, the Chenqi CQ square bottom paper bag machine boasts outstanding cost performance, perfectly suitable for small, medium, and large-scale paper bag processing factories.
