Unwinding Unit
- Equipped with a double-station unwinder.
- Uses a double-station cylinder-driven loading arm for automatic material loading. During operation, simply push the fabric roll into the loading position of the arm. Once the roll is loaded, the first station waits to connect with the second station’s fabric roll. When the roll diameter at the current station becomes smaller and reaches the set changeover size, the system automatically performs a non-stop splicing and roll change with the roll at the current station.
Pneumatic Disc Brake
- Uses signal feedback from the double-station unwinding shaft to monitor rotational speed, enabling real-time measurement and display of the roll diameter. When the roll reaches the preset changeover diameter, the system issues an alarm and automatically reduces speed, making overall machine control easier.
- Equipped with automatic stop when material breaks; tension is automatically maintained during stoppage. When restarting, the tension remains unchanged, effectively ensuring printing accuracy is not affected during start/stop operations.
- Fitted with a photoelectric servo web guiding device. An infrared photoelectric sensor detects the edge of the woven fabric as the reference point for web guiding.
- Equipped with a 3-inch air shaft (customizable upon request). The air shaft is made of aerospace-grade aluminum, making it lightweight yet highly durable.
- All unwinder operations are centrally controlled from the main control console. The unwinder’s sub-control console can also independently operate the unwinder and coordinate with the entire machine. The whole machine can be operated by a single person, with multiple control points available.
Corona Treatment Unit
(Intelligent Corona Treater)
- Equipped with an intelligent corona treater. The main unit adopts the latest integrated circuits and high-power IGBT modules, offering excellent corona discharge performance, low failure rate, and long service life.
- Controlled via a touch screen, the corona power automatically and precisely adjusts according to the equipment’s production speed. It also features power-off protection when the main equipment stops or operates at a preset low speed.Includes a discharge frame stop-and-power-off protection function. Multiple protection measures effectively prevent long-term corona sparks from damaging the woven fabric and silicone sleeve, thereby avoiding potential fire hazards. This also significantly extends the service life of the silicone layer on the corona roller, effectively reducing daily maintenance costs and the expense of consumable parts.
- Integrated design: The corona treater control cabinet is combined with the main equipment, saving space. At the same time, the high-frequency high-voltage wiring is shorter, effectively improving equipment safety.
- Front-facing observation window: Allows operators to conveniently monitor the corona treatment at any time, making it easy to adjust the treatment effect as needed.
- Oil-immersed step-up transformer: Provides excellent heat dissipation, durability, and long service life.
- Dual output function: Can output dual high-frequency, high-voltage lines for corona treatment or a single high-frequency, high-voltage line, allowing easy adjustment according to operating conditions.
- Thick-layer sensing device: Detects the approach of woven fabric joints or thick layers and automatically retracts the corona discharge frame to avoid damage to the discharge electrodes.
- Segmented electrode customization: Can be tailored according to material width for targeted treatment, ensuring excellent corona effect with minimal tensile damage to the material.
Process Deviation Correction and Intermediate Tension

Printing Unit
- The printing unit adopts a modular structure, configured with a front 3-color and back 3-color modular printing group (or front 4-color and back 2-color).
- The main wall plates and chassis of the printing unit adopt a thickened and reinforced structure. After undergoing aging treatment, they are precisely machined using a large-scale machining center, effectively ensuring the equipment’s accuracy and the machine’s stability during long-term high-speed operation.
- The printing groups are powered by first-class domestic brand Inovance Technology, with independent servo motor drives (electronic shaft synchronous transmission). A coaxial direct-drive structure is used, with the servo motor directly connected to the reducer, eliminating gears for higher transmission efficiency and easier maintenance.
- An ink transfer method combining a ceramic anilox roller with a rubber roller is employed. The side ends adopt a sealed structure, effectively preventing ink misting, splashing, and leakage.
- An upper-web path frame is adopted, with a centrally positioned pre-print traction unit. This reduces the web threading length and shortens the distance from the traction unit to the printing group, thereby improving printing accuracy and operational stability.
- Equipped with an automatic inking system, utilizing a pneumatic diaphragm pump for continuous ink circulation.
Drying Unit
- Independent recirculating, closed-type drying ovens are provided separately after front-side printing and after back-side printing.
- Each oven adopts an internal heat-insulation double-panel structure, offering easy maintenance and high energy efficiency.
- Each drying oven is equipped with temperature control, using temperature control modules for independent regulation, ensuring convenient maintenance.
Rewinding Unit
back-to-back rewinder
- Rewinding power is driven by an asynchronous gear motor, offering quick synchronous response, high precision, high transmission efficiency, and lower energy consumption.
- The roll-change air shaft (spare rewinding shaft) is automatically lifted by a flip arm, rotating into position for roll change. This ensures safe and effortless operation.
- A servo flying-knife system is used for web cutting, with a pneumatic arm pressing the roll-change shaft for web splicing, enabling fully automatic, non-stop roll change under optimal operating conditions.
- The rewinding shaft uses a 3-inch aluminum air shaft (customizable to customer requirements) to meet the production process requirements of square-bottom heat-seal bag-making machines. The air shaft is made of aerospace-grade aluminum, offering light weight and high strength.
- Equipped with an electric lifting mechanism for the up-and-down movement of the rewinding air shaft, ensuring that one person can easily replace it.
Control Unit
(Touch Screen Control Panel)
- The equipment adopts an electronic shaft architecture, with all drive power provided by servo systems. A motion controller manages each servo system and key associated operations, integrating tension control, corona treatment, and centralized control into one system. This ensures fast response speed, high control precision, excellent synchronization, and truly intelligent, integrated operation.
- The human–machine interface (touch screen) allows data setting and modification. The main screen displays the machine’s operating status, including production line speed, shift output, total output, single roll length, and total length. Additional screens can display operating parameter monitoring/recording, historical data records, and alarm notifications.
- Unwinding tension, post-printing tension, and rewinding tension are all centrally controlled by the motion controller, with real-time display of each tension value, enabling clear visibility of the production status and easy operation.
- The central master control console and each sub-control station are linked for coordinated group control. Each sub-control station can operate its own independent functions. Multiple emergency stop buttons are provided, along with a remote-control panel for wireless operation.
- The main UI screen on the touch panel can simulate and display the images of each functional unit of the equipment, as well as all set parameters and operating statuses of these units, providing highly user-friendly operation.
