1.Frame: The frame of this machine adopts steel plate welded box
structure. The column of the box structure has the characteristics
of resistance to bending and torsion. The base plate is cast iron.
The components of the frame are connected by screws to form a
whole. Frame structure, with extremely high stability and rigidity. 2.Calender roller and bearing: The material of the calender roller
is ordinary cold hard cast iron, the hardness of the roller surface
is 70Hs (Shore hardness), the condensation layer is 15-20mm, the
bearing is a double-row short cylindrical cylindrical ball bearing,
the roller journal and The bearings are connected with a withdrawal
sleeve. The calender roller bearing shell is fixedly connected to
the lifting arm, the lifting arm is movably connected to the
support, and the support is fixedly connected to the column 3.Activated curved roller 4.Lifting system: The lifting of the calender roller is
pneumatically controlled. 5.Pressure system: This machine has a set of pressurizing
mechanism, namely the pressurizing mechanism on the top roller. The
upper pressurizing mechanism is an independent pressurizing
mechanism 6.paper guide device 7.Scraper: This machine has two sets of scrapers, namely the left
scraper of the top roller and the bottom scraper of the bottom
roller. The scraper blade is EP high-strength epoxy resin laminate,
which has abrasion resistance and does not hurt the roller surface. 8.Safety device: This machine is equipped with two sets of bumpers
for safety protection. 9.Lubrication system: Grease lubrication |
