Garden Hose Pipe Extrusion Machine PLC Control System Water Cooling Bath

• Soft PVC compound material color mixer ( Optional)

 
PVC compound material color mixer machine is main used in PVC compound resin adding, drying, coloring and mixing with master batch according to different colors requires for making different colors of PVC thunder hose pipe function purpose.
 
PVC compound material color mixer machine is composed of silo,motor, gear reducer box, stir blade and control cabinet.
 
If soft PVC part of PVC braided hose pipe color is transparant, then we didn't need this mixer machine. It is optional only.
 
 

• Vacuum Loader Machine

 
Vacuum loader machine is used for loading soft PVC compound resin material into hopper on the top of extruder from ground. Soft PVC compound resin material will be transported by vacuum covery in the middle of soft PVC suction hose pipe automaticly. It is controlled by timer too. The working principle of this vacuum loader is negative pressure.
 
 

• Single Screw Extruder

 
Single screw extruder is main part of soft PVC garden hose pipe making machine line. It is used for feeding,transporting, plasticing,melting soft PVC compound resin material.
 
Single screw extruder is composed of driven motor, gear reducer box, screw and barrel, casting aluminum heater, cooling blower, hopper and control cabinet.
 
Driven motor: It is main part of single screw extruder. We'd better choose good brand AC type driven motor matching with inverter controll for saving power running cost.
 
Gear recuder box: It is used for connecting motor and for reducing rotating speed of screw through size and teeth of gear changing in the gear box.
 
Screw and barrel: It is most important part of single screw extruder. Design of single screw is becoming to special and customzied now due to many different kind plasic materials are using. The surface of screw should be paint double alloy for anti-wear.
 
Casting aluminum heater: It is used for heating barrel and screw which ensure mixed soft PVC resin material can be plasticizing and melting under the suitable temperature.
 
Cooling blower : It is used for cooling barrel and screw. if temperature of screw and barrel will be excess setting temperature, cooling blowers start to work for cooling barrel which avoid soft PVC material resolved in the inside of barrel.
 
Hopper : It is used for keep the mixed soft PVC resin material in the silo and make sure material can be into barrel continuously. It is like a material transport station.
 
Control Cabinet: It is used for control whole cornic double screw extruder running by switchs or PLC programes according to different circuits control required.
 

• Extrusion Mould & Die Head

 
Extrusion mould and die head is one important part of soft PVC garden hose pipe production line. Soft PVC compound material will be forced into extrusion die through connect flange by screw forward transported after plasticizing and melting in the inner side of barrel.
 

• Water Cooling Bath

Water cooling bath is main used for cooling hot soft PVC garden hose pipe which is from extrusion mould die. Bath body is made by stainless steel because of there is water inside of bath and it is should be anti-rust. Length of tank is must be enough to cooling down the temperature PVC thunder hose pipes .
 
In normal, length of cooling bath is 4 meters to 6 meters according to pipe diameter ranges and thickness of soft PVC garden hose pipe .
 
Water spray system is used for transpoting cold water and spraying cold water on the surface of  soft PVC garden hose pipe for reduce the temperature of pipes through the several spray nozzles .
 

• Haul-off Unit Machine/ Traction Machine

 
Haul-off unit machine/ traction machine is main used for clamping and pulling the soft PVC garden hose pipe forward a long length at a constant speed through rubber pad which located on each pedrail.
 
It consits of driving motor, pedrail/ pulling belt, air cylinder, rubber pad. Haul -off units/pulling machine for soft PVC garden hose pipe will be equipped two pedrails/pulling belts only according to diameter of pipes is no more than 160mm.
 
Pedrails/pulling belts are located under the extrusion axis, which are mechanically adjustable and upper ones are driven by pneumaticlly.
 
Special silicon rubber pad on each pedrail/pulling belt is soft and anti-wear, which make sure pedrails do not damage soft PVC garden hose pipe and there is no marks on the surface of soft PVC garden hose pipe

• Coiler

Coiler is used for winding PVC soft PVC garden hose pipe automaticly. There are two type of coilers, one type is single disc coiler, anther one is two disc coiler.  This machine is suitable for winding this kind soft PVC garden hose pipe which is pulled out of he front road, which adopts automtiac winding, adjusting the winding speed, winding tesion mode with two alternate winding to ensure continuity. The pneumatic opens or closes, and equipped with cable rod, automatic cable to cable uniform, regular coiling, compact structure, high degree of automation.
