New Generation 75 Parallel Twin-Screw TPU Hot Melt Adhesive Toe Puff Extrusion Line High-Capacity Exclusive Model

This production line is a high-capacity upgraded core equipment for shoe material toe puff manufacturing. Equipped with the new-generation 75 parallel twin-screw extruder as the core power, it is specially built for large-scale production of TPU low-temperature hot melt adhesive toe puff sheets. It integrates four core advantages: ultra-high production efficiency, precise plasticization, wide raw material adaptability, and intelligent easy operation. It can realize continuous and high-quality mass production of toe puff sheets for toe cap/heel shaping, perfectly meeting the high-capacity needs of medium and large shoe material factories and professional toe puff manufacturers, greatly reducing unit production costs and enhancing market competitiveness.

Core Powerhouse: New-Generation 75 Parallel Twin-Screw Extruder, the Core Engine for High Capacity

1. Ultra-High Production Efficiency, Doubling Output

The 75 parallel twin-screw adopts a cross-type high-shear + double venting structure, with plasticization efficiency nearly doubled compared with traditional single-screw extruders. For 1mm standard thickness toe puff sheets, the hourly output can reach 450+ yards (about 412 meters/hour), with daily mass production exceeding 10,000 meters, far higher than conventional models, easily meeting large-batch order demands.

2. Precise Plasticization, Stable Quality

With customized screw compression ratio and mixing mechanism for TPU, combined with melt rheology analysis optimized design, it achieves full plasticization uniformity. The produced toe puff sheets have a thickness tolerance within ±0.05mm, free from glue shortage and bubbles, with strong shaping force, excellent elastic recovery and outstanding adhesion, suitable for high-end shoe material needs such as high-grade women's shoes, sports shoes and casual shoes.

3. Low Energy Consumption & Cost Control

The twin-screw features high transmission efficiency, with energy consumption per unit output reduced by more than 15% compared with traditional models. There is no need to pre-dry raw materials, and direct feeding is available for production, saving the time and energy loss of the drying process and further reducing production costs.

Full-Line High Configuration, Dual Guarantee of Quality and Stability Under High Capacity

1. Key Components, Wear-Resistant and Durable for Uninterrupted Production

Core components such as screws, barrels and casting dies are all made of high-quality 38CrMoAlA nitrided steel, treated with nitriding + surface alloy spraying, which are wear-resistant, corrosion-resistant and high-temperature resistant. They are suitable for processing TPU low-temperature hot melt adhesive at 120-160℃, avoiding material degradation, extending equipment service life and reducing downtime for maintenance.

2. Intelligent Die + Quick Screen Changer, Fast Product Changeover & Non-Stop Operation

u Adopting casting die with melt rheology analysis technology, combined with CAD/CAM/CAE high-precision processing, the lip is precisely adjustable, supporting free switching of thickness from 0.3-2.0mm and width from 670-1400mm. The 3D adjustable design allows quick product changeover without cumbersome debugging, completing specification switching in a few minutes.

u Standard-equipped with hydraulic quick screen changer, with humanized operation, enabling non-stop screen changing, avoiding production interruption caused by screen changing and ensuring 24-hour continuous and stable operation of the production line.

3. Efficient Cooling + Precise Traction, Fast Forming & Neat Winding

uThe main machine roller adopts internal spiral cooling structure, with fast cooling speed, enabling rapid forming of toe puff sheets with flat surface and no warping. The roller gap is easily adjustable, adapting to shaping needs of sheets with different thicknesses.

u Constant-tension servo traction + intelligent winding/cutting system ensures neat winding without deviation, supporting two discharging methods: fixed-length cutting and roll packaging, adapting to different packaging and usage needs of shoe material factories without manual intervention throughout the process.

4. Wide Raw Material Adaptability, Efficient Production Even with Recycled Materials

The 75 parallel twin-screw is designed with double vents, which can quickly discharge moisture and impurities in raw materials. It can directly process recycled materials, modified materials and compound formula materials without drying, realizing unlimited raw material adaptability. It not only meets environmental protection requirements, but also further reduces raw material costs and improves product profit margins through the use of recycled materials.

Full-Line Intelligence, Simple Operation & Convenient Maintenance

1. Equipped with PLC + touch screen intelligent control system and Ethernet transmission technology, parameters such as speed, pressure and temperature are displayed and precisely controlled in real time, supporting parameter storage and traceability. One-click start for production, easy to get started even for new operators.

2. The system is built-in with fault self-diagnosis + remote maintenance function, enabling quick location of equipment faults and remote debugging without on-site professional personnel, greatly reducing debugging and downtime and ensuring production capacity utilization.

3. The reduction gearbox is made of cast steel, with gears processed by gear grinding, and equipped with forced lubrication + water cooling system, featuring low operating noise and strong stability. Daily maintenance only requires simple cleaning and lubrication, with extremely low maintenance costs.

Optional On-Line Lamination Unit, Realizing Integrated Production of "Sheet + Lamination"

The production line can be optionally configured with on-line lamination device for mesh fabric/cloth, realizing one-time lamination of TPU hot melt adhesive toe puff sheets with mesh fabric/cloth, directly producing laminated toe puff finished products, eliminating the subsequent manual lamination process, further improving production efficiency, reducing labor costs, ensuring firm lamination without delamination, and meeting the laminated shaping needs of high-end shoe materials.
