VEST-430×2 High speed Automatic Vest Bag making Machine (Two Lines)
1. Special design with a view to keeping the punching hold in the suitable place. It can make the bottom of the bag well arranged and orderly in a block.
2. It uses the auto conveyor belt to collect the punching waste, which is easy to tidy up.
Product Features
1. This machine can produce natural color and printed vest bags using HDPE, LDPE, LLDPE, and other materials as raw materials. Using a computer programming control system and servo motor automatic length setting, the entire process of feeding, sealing, cutting, punching, and conveying is completed in one go.
2. Configure two servo motor control systems with computer control and PLC LCD screen display, combined with photoelectric eye tracking control, for more efficient operation, smooth bag making, and accurate sealing and cutting.
3. The design of the automatic feeding system, automatic punching machine folding device, and conveyor belt bag feeding function makes the operation more convenient and the bag making process more stable.
4. Swing type discharge system, combined with bag bottom shaping design, ensures neat bag collection and accurate punching position.
5. The cutting blade adopts current independent heating, a high precision temperature controller for automatic temperature control, easy operation, and accurate temperature control.
Against the backdrop of large scale upgrading of the global plastic packaging industry, flagship bag making equipment featuring high productivity, high precision, and low failure rate has become an essential demand for packaging factories to cut costs and boost efficiency. As a leading manufacturer in the packaging machinery industry, Wenzhou Chenqi Machinery proudly launches the VEST-430×2 dual lane high speed automatic vest bag forming & making machine. As our flagship model, it is fully equipped with imported electric control components to realize synchronous automatic dual channel production, with a stable maximum speed of 350pcs/min per lane. Powered by premium hardware and mature manufacturing technology, it stands as the preferred high end equipment for manufacturers producing supermarket shopping bags, market vest bags, and biodegradable PE bags worldwide.
Flagship Full Servo Electric Control, Imported Core Components Ensure Stable Operation
This machine adopts a full servo closed loop control system, equipped with Japanese Yaskawa servo motors as the core power unit, paired with original Delta frequency converters to regulate overall power output. It delivers fast power response, precise speed adjustment, no inertial jitter during start and stop, and consistent power during long term high speed operation. The complete electric control system boasts strong resistance to voltage fluctuations, compatible with industrial voltage standards in most countries worldwide. Servo positioning error is controlled to an extremely low range, eliminating common defects of traditional frequency conversion machines such as inconsistent bag length, uneven sealing and cutting, and stalling at high speeds. Uniform finished bag dimensions effectively reduce the reject rate in production.
The machine comes standard with an integrated automatic photoelectric web guide frame and precision pinch roller feeding structure. The high precision pinch roller set is made of wear resistant and anti slip material, which clamps film materials under constant tension for even feeding without stretching or deviation. The supporting automatic web guide system monitors left right film offset in real time and dynamically corrects the running path automatically. It achieves accurate alignment for both plain film and printed color film during full-load non stop long hour operation, ensuring smooth film conveyance. It is perfectly compatible with multiple raw materials including HDPE, LDPE, and fully biodegradable films, supporting production of regular shopping vest bags, printed advertising bags, and eco friendly degradable garbage bags.
Dual Channel High Speed Design, Doubled Productivity for Maximum Production Efficiency
The VEST-430*2 features a standard synchronous dual lane production line of the 430 series. Its maximum bag width per lane reaches 400mm, maximum bag length 650mm, and applicable film thickness ranges from 0.010mm to 0.025mm. The peak output hits 350 pieces per minute for a single lane, with a combined dual lane capacity of 700pcs/min — double the productivity of ordinary single lane machines. It doubles production output within the same workshop footprint without factory expansion, easily handling bulk orders and urgent peak season demands.
The whole production process achieves fully automatic unattended operation: raw material unwinding, automatic film feeding, photoelectric color tracking positioning, hot sealing & hot cutting, automatic punching of vest handle holes, neat stacking of finished products, and automatic waste recycling are completed in one integrated workflow. Only one worker is required for material loading/unloading and parameter monitoring. Built in functions include automatic counting, automatic shutdown, and alarm for film shortage, material breakage, and material jams, which prevents raw material waste and idle machine wear. High intelligence drastically cuts labor costs and enables lean production for factories.
Heavy Duty Precision Body Structure, Durable & Stable for Long Term Continuous Industrial Production
The machine frame is integrally welded with thickened heavy duty steel plates, featuring high rigidity and excellent shock resistance with no resonant shaking during high speed operation. Constant temperature precision temperature control components are fitted for heat sealing blades, delivering firm and tight seals free of cracking or edge leakage. The combined hot & cold cutting process balances bag toughness and clean cutting edges. The punching station is specially optimized to produce smooth handle holes without burrs, with an automatic conveying and collection device for punching waste to keep the workshop tidy.
As Chenqi Machinery’s flagship model, the VEST-430*2 has passed tens of thousands of hours of comprehensive fatigue testing. Its wearing parts enjoy a far longer service life than conventional industry models, with a low overall failure rate and easy daily maintenance. Manufactured in strict compliance with EU CE industrial standards, every unit undergoes complete trial run inspection before delivery. Custom modification is available, and the machine can connect with upstream film blow molding machines and flexographic printing presses to form a complete one stop PE bag production line, providing full solution support for packaging workshops.
