Explosion Proof Film Slitting Machine
Detail description: suitable for explosion proof film slitting and
rewinding.
Characteristics:
1. The two rewinding motors cooperate with the main motor to work
as three motors motion control, the main motor blocks the unwinding
and the rewinding motor control the tension, the tension of the
finished product is stable, good rewinding appearance.
2. The rewinding arm adopts the pneumatic coupling control the
balance, the contact pressure can be adjusted automatically during
rewinding, the contact pressure can be set. This machine can also
be equipped with discontinuous rewinding, cut other materials more
widely.
3. The operation interface adopts LCD touch screen, various
rewinding conditions and working conditions can be set directly on
the screen, the control part adopts PLC to control the machine
operation, with self-test system.
4. The machine drive uses AC motor and frequency inverter;
acceleration and deceleration are stable and fast.
5. Optional with slat type air pressure shaft and pneumatic
friction shaft, suitable for more material range, the shaft change
is specially designed, can be change at any time.
6. Auxiliary discharge device, the material outfeed pass surface
impression roll, material more even, and reduce the noise (suitable
for adhesive material)
7. Separate type unwinding stand, for bigger unwinding diameter.

SECTIONS OF MOTHER ROLL PRODUCTION PROCESS
The first is the forming section, which has the main purpose of
draining excess water from the slurry while arranging the mixture’s
solid materials into a continuous layer. This can be accomplished
through the use of gravity, shaking, vacuum, and tension. Once the
majority of the loose water has been drained from the slurry, the
sheet is carried into the press section, where a series of
revolving cylinders (called “drums”) use pressure and felt to
squeeze out the remaining moisture and to remove it through
absorption.
Once the sheet has undergone forming and pressing, and the liquid
has been removed, the damp remaining material is carried through a
series of steam-heated machines in the dryer section to completely
dry the sheet. After drying, the paper material is essentially
created, but requires a number of finishing processes in order to
attain the desired appearance, feel, and performance. It first
undergoes a process called sizing that determines the paper’s water
resistance and reduces the potential for fuzz through the addition
of different glues and resins. Following that, the large paper
sheet passes through a process called calendaring, where it is
again pressed, but this time with the goal of finally increasing
smoothness, gloss, and uniformity. At this point, the continuous
sheet of finished paper is wound onto large metal spools, and
finished rolls of paper have been created.
It may not have escaped your notice that a slitting rewinding
machine was not mentioned at any point in the above process. That’s
because the slitter rewinder is normally employed after all of the
above has been accomplished. Once the manufactured paper has been
created and is already standing in rolls on the exit end of the
finishing process, it can then be unwound, fed into the slitter
rewinder, cut into narrow strips of any desired width, and rewound
back onto multiple smaller spools on the other side.
