Oiling mechanism is positioned close to the surface external of upper roller and lower roll, and the oiling mechanism is used to apply oil to upper roller and lower roller surface
Product, the infrared heating mechanism are used to make oil product form a film to upper roller and the heating of lower roller surface.
Preferably, the motor is alternating current generator, and the upper roller and lower roll are electrically connected with alternating current generator respectively.
Preferably, the oiling mechanism includes cylinder, idler wheel sponge hairbrush, and the cylinder is connect with idler wheel sponge hairbrush,
Up and down motion by controlling cylinder makes the upper roller and lower roll of idler wheel sponge hairbrush contact rotation, inhales on the idler wheel sponge hairbrush
With oil product.
Preferably, the oil product is organism mixing oil product, and the material molecule for being rolled object plays repulsive interaction.
Preferably, the heating mechanism is infrared heating mechanism or hot wind heating mechanism.
The utility model has the following beneficial effects:
1. upper roller and lower roll can be distinguished by AC Motor Control by the current direction and output power for controlling alternating current generator
Change direction of rotation and the roll surface speed of upper roller and lower roll.
Realize that upper roller surface is contacted with lower roller surface and applied to lower roller surface 2. moving up and down with the hydraulic cylinder of upper roller connection
Add constant pressure, controls direction of rotation (upper roller direction of rotation and the lower roll rotation of upper roller and lower roll respectively by alternating current generator
It is contrary) and it is kept in contact that roll surface speed is consistent, it can be achieved that pole piece is toward a direction roll-in, above and below irregular synchronism switching
Roller motor current direction realizes reciprocating roll-in, reduces the stress deformation of roll-in pole piece.
3. after roller surface applies oil film and dries, roll surface contacts pole piece by setting heating mechanism and oiling mechanism
It is not easy roll banding, guarantees that roll-in pole piece will not be dropped off because of roll banding.
4. oil product uses organism mixing oil product, the material molecule for being rolled object has repulsive interaction, remains on roller
A small amount of oil product in pole piece after pressure can vapor away in rear process high-temperature baking, not generate to original pole piece chemical property
It influences.
Detailed description of the invention
Fig. 1 is the novel rolling device structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing:
Refering to Figure 1, the utility model provides a kind of novel rolling device, including motor, upper roller 1, lower roll 2,
Hydraulic cylinder 6, heating mechanism 5 and oiling mechanism, the upper roller 1 and lower roll 2 by motor driven rotate, the hydraulic cylinder 6 with it is upper
Roller 1 connects, and the hydraulic cylinder 6, which moves up and down, to be realized 1 surface of upper roller contact 2 surface of lower roll and apply constant pressure, institute to lower roll 2
It states heating mechanism and oiling mechanism is positioned close to the surface external of upper roller 1 and lower roll 2, the oiling mechanism is used for upper roller 1
Oil product is applied with 2 surface of lower roll, the heating mechanism 5 is used to make oil product form a film to upper roller 1 and the heating of 2 surface of lower roll.
The motor is alternating current generator, and the upper roller 1 and lower roll 2 are electrically connected with alternating current generator respectively, is exchanged by changing
The current direction of motor exchanges to change the direction of rotation of upper roller and lower roll since upper roller individually connects one with lower roll
Motor, so the direction of rotation of upper roller 1 and lower roll 2 can be on the contrary, can change 1 He of upper roller by the output power for changing motor
The roll surface speed of lower roll 2.Upper roller direction of rotation with lower roll direction of rotation on the contrary, and to be kept in contact roll surface speed consistent, can
Pole piece is realized toward a direction roll-in, irregular synchronism switching up-down rollers current of electric direction is realized reciprocating roll-in, can be reduced
The stress deformation of roll-in pole piece.
