Low Temp Hot Melt Toe Puff Production Equipment,Spunlace Fabric Laminated Thermoplastic Sheet Machine

Low Temp Hot Melt Toe Puff Production Equipment,Spunlace Fabric Laminated Thermoplastic Sheet Machine

1. Product Overview

2. Complete Line Composition

1. Automatic Mixing & Vacuum Feeding System
   
   Closed auto batching unit for TPU pellets, EVA granules, powder additives and chopped spunlace nonwoven scraps; vacuum feeding avoids dust leakage and raw material bridging, improves formulation consistency.
2. Main Extruder Unit

• Parallel Twin Screw Extruder:  screw with multi-section exhaust structure, effective moisture removal from spunlace fabric, strong plasticizing capacity, output 400~750kg/h for high-yield composite sheet production; equipped with ABB frequency converter and Omron segmented temperature control, precision ±1℃, ideal for high filler spunlace composite formulation.
• Single Screw Extruder: L/D 32:1 nitrided barrel, cost-effective for low-filler pure TPU/EVA single-layer toe puff sheet, output 150~300kg/h.

1. T-Die Head & Three-Roll Calender Forming
   
   Mirror chrome plated adjustable T-die, gap precision 0.01mm; three-roller constant-temperature calender realizes synchronous lamination of plastic melt and spunlace nonwoven, uniform sheet thickness 0.15~2.5mm, no bubbling or delamination between cloth and plastic layer.
2. Cooling, Traction & Servo Cutting Unit
   
   Circulation water cooling rack + variable speed caterpillar haul-off; servo fixed-length slitting & cutting, cutting tolerance ±0.3mm, optional online edge trimming.
3. Constant Tension Winding Machine
   
   PLC-controlled auto winding for finished toe puff rolls, adjustable winding tension to prevent sheet stretch deformation, roll specification customizable.
   
   Full set line adopts centralized touch screen PLC control, one-key save production formula for fast material switching.

3. Applicable Raw Material & Finished Product

• Raw materials: TPU particle, modified EVA, spunlace nonwoven fabric, hot melt additive, filler powder
• Finished goods: Low temp thermoplastic toe puff sheet, heel counter chemical sheet, spunlace composite shoe lining sheet for casual shoes, leather shoes, sneakers, safety boots
• Sheet width range: 600/1000/1200/1600mm customizable

4. Core Equipment Advantages

1. Integrative compound extrusion: One-step lamination of plastic + spunlace cloth, cancel secondary coating process, save production cost
2. Wide formula adaptability: Switch pure plastic sheet / cloth composite sheet only by changing formula and feeding mode
3. Stable finished quality: Composite layer no peeling, low-temp hot melt characteristic fits global shoe factory cold press molding craft
4. High automation, less manual operation, finished toe puff meets international footwear raw material inspection standard
