Shrinking Shrinkage shink compacting machine
Constant tension feeding device
This device consists of body frame,active draw shaft,R shape fabrics trunk,slide pannel, Footboard and photoelectric controllers. Its function is feed the fabrics into machine smoothly, eliminate the unstablility of fabric’s width and shrinkage caused by tension fluctuates.
Overfeeding device and holder
Four wheel driving, the position of the overfeeding wheel is driven by leading screw,electric adjustment,easy to operate.The overfeeding wheel is made of Polyurethane material,which has long life span. The holder is newly designed magnetic fluctuate model; there is no connection element between the left and right parts. Width can be adjusted in the range of 350mm-1450mm ,during the adjustment,no need change folder,no need stop the machine.
It is made of stainless steel and double layers structure, upside nozzles are concave shapes and underside nozzles are convex shape, the design can prevent condensed water ejection. Main pipe equipped a stainless ball valve to control the steam volume. The steam device also includes a vapor liquid separator and a condensing device.
The upper part of Steam box can be opened by air cylinder, convenient to feed fabrics, when start the machine it close automatically.
The compacting section is the main part of the machine, this part includes electric oil cylinder,20mm ring felt and damping plate.
After steam humidification, the fabrics enter to the compacting and setting unit, The fabrics is compacted between the felt and damping plate,after the fabrics leave the damping plate,it goes into the setting area between cylinder and felt. The fabircs will be setted size under the high temperature cylinder,after the process, the fabrics obtain stable width and gloss soften surface.
The cylinder temperature can be adjust according to the process requirement , and controlled by a thermo-regulator, the temperature control precise ±1°C.
The pneumatic device is used for direct the moving route of felt, the felt is tensioned by pneumatic cylinder and pressure is adjustable.
The main speed is the first cylinder speed, the second cylinder speed change follow the first speed, between the first cylinder and the second cylinder set with a tension adjust roll, which can keep the fabrics tension stable.
Conveyor is a special belt, its function is transport fabrics tensionless, and the fabrics on the belt does not drift. The speed is controlled by main speed.
Folding device include body frame,a pair of guide roll,pressure plate,lifting table and hydraulic system. The movement of lifting table is controlled by hydraulic, it fall automatically with folding height, and the fabrics can be transport out of the folder by conveyor belt automatically.
The machine is droved by 4 gear reducer motors, the motor droved by inverter and controlled by PLC, HMI operating. Overfeeding ratio and main speed can be adjust according to process requirement, the set parameter memory storage when stop machine.
The electrical system consist of electric cabinet,PLC,inverter, synchronous controller,temperature controller,air breaker and operation panels.
