Specifications
The machine is chiefly applied to put rubber on both sides of fabrics (cord fabric, canvas, etc.); to rubberize fabrics; etc.STRUCTURAL FEATURES:
The 4 rolls are separately driven by 4 DC motors, which allow a wide rang of speed adjustment. The rotating speed ratio of the 4 rolls can be freely adjusted. The rolls are equipped with per-loading device and lubrication failure alarm device, as well as nip display and speed display.
The rolls are made of chilled cast iron of vanadium and titanium alloy. The roll face is hard and anti-wear. For heating up or cooling down, the rolls are either circumferentially drilled or centrally bored so as to make temperature well proportioned on the roll surface.
The rolls are arranged in S form. Roll 1# and roll 4# have roll cambers that can eliminate bending impact on rolls in the working process. Thus it is possible to make products with same thickness along axial direction.
The transmission system adopts a hard-gear speed reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life.
The machine is equipped with emergency device. When an emergent accident occurs, the calendar will be immediately stopped to open the roll space so as to protect the operator and equipment.
PLC program controller is used in the electric system.
Application:
The machine is chiefly applied to put rubber at the same time on both sides of fabrics (cord fabric, canvas, etc.); to rubberize fabrics; or to make rubber sheets; or to join rubber sheets together.
