TPU Thick Sheet Extrusion Equipment Introduction
The polyurethane thermoplastic elastomer TPU thick board extrusion line produces TPU thick sheets which are used to make supercritical foaming boards.
Supercritical microcellular foaming technology, as animportant method of physical foaming method, isenvironmental-friendly: no "three wastes", no pollution.no residue, and recyclable products
The foamed TPU Board has comprehensive properties:excellent mechanical properties,flame retardancyweather resistance, so it is widely used in:
Sports equipment: such as running shoes, snowboards,skateboards, bicycles, etc.
Packaging industry:Packaging materials, such aspallets, cushioning pads, etc.
Sole material: sole material of running shoes.
Composition of TPU thick sheet extrusion equipment
TPU thick Sheet Extruder:
1)Adopting the latest design of exhaust screw toachieve complete TPU plasticization, without anycrystal points,bubbles, or black spots.
2)Adopting a plate type hydraulic screen changerfor convenient and fast cleaning.
3)Adopting an online exhaust design, exhaustingthe moisture from melt plastic.ensures a brightsurface of TPU sheets without defects such asbubbles.
4)Adopting a melt pump and an imported pressuresensorto achieve aclosed-loop control.
5)adopting Siemens PLC control for the supercritical foaming use TPU board extrusion line.It has a formula memory function. Convenient forrecording recipes and quick startup.
Vertical three-calender-roller stack:
1)Adopting two rollers with mist surface designed toavoid TPU sheet sticking on rollers.
2)Adopting a fully automatic roller gap adjustingservo controlsystem,achieving digitalinputautomatic adjustment andonlinereal-timeadjustment function,ensures the even sheetthickness.lt can be used in conjunction with anautomaticT-dies for a better thickness control.
Air cooling stand and oven:
1)a 1500mm long oven is used to heat the sheetsurface in order to remove stress of sheets. Theseveral zone temperature control design facilitatestemperature adiustment.
2)Using aluminum guide rollers for sheet supportand cooling design.
3)online-mechanical-knife-trimming design,convenient and practical.
Two-roller haul-off unit:
1)Online real-timelength calculation.
2)The haul-off speed can be synchronized with the three rollers and be adjusted independently as well.
Hydraulic cutting machine:
1)Using hydraulic style cutting. The work spot isfree of debris, clean and neat.
Three axis servo robotic arm:
1)Using vacuum suction cups for materialextraction and unloading.
2)Precise online servo design and control, improving production efficiency and saving manpower
