Embodiment
In order to make the object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. It is to be understood that specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
As shown in Figure 1, a kind of calender device that the better embodiment of the present invention provides, comprise the first calendering roller 1 and the 2nd calendering roller 2 of parallel setting, first calendering roller 1 is coated with the first barrier film 3,2nd calendering roller 2 is coated with the 2nd barrier film 4, the off-type force of the first barrier film 3 is greater than the off-type force of the 2nd barrier film 4, and material 500 sticks on the first barrier film 3 under the first calendering roller 1 and the 2nd extruding rolling roller 2, and the outside surface of the first calendering roller 1 and the 2nd calendering roller 2 is cambered surface.
The material 500 that thickness can be greater than 0.25mm by the calender device of the present invention is rolled into the film that thickness is 0.003��0.005mm. The material 500 of the present embodiment is lithium band, and owing to the supplied materials thickness of lithium band has difference, the lithium band that thickness is 0.25mm��0.5mm can be rolled into, by repeatedly calendering, the lithium film that thickness is 0.003mm��0.005mm by above-mentioned calender device. It should be appreciated that the application does not limit the concrete material of material 500, material can also be copper strips etc.
In calender line, in order to not make lithium film stick on the first calendering roller 1 and the 2nd calendering roller 2, it is necessary to roll at two and arrange barrier film between roller and lithium film, so that lithium film and two calendering rollers are isolated. Shown in composition graphs 2, the two ends of barrier film are connected to unreeling structure 100 with, on rolling-up mechanism 200, owing to unreeling structure 100 and rolling-up mechanism 200 are the conventional techniques means of prior art, its concrete structure does not repeat them here. In order to avoid the lithium film rolled to be attached on two barrier films simultaneously, the size of the off-type force of two barrier films of the application is different, and the lithium film rolled is attached on the big barrier film of off-type force and is pulled away. In the present embodiment, the off-type force of the first barrier film 3 is greater than the off-type force of the 2nd barrier film 4, and lithium film is attached on the first barrier film 3 and is taken away by the first barrier film 3.
As shown in Figure 1, calender device comprises frame (non-label), and frame is provided with feeding mechanism, roller mechanism, fine setting clearance mechanism 5, color mark sensor 6 and the mechanism 7 that exerts pressure. Wherein, roller mechanism comprises the first calendering roller 1 and the 2nd calendering roller 2, the two ends of the first calendering roller 1 are provided with the first bearing support 10, the two ends of the 2nd calendering roller 2 are provided with two bearing bracket 20, and material 500 (such as lithium band) is sent between the first calendering roller 1 and the 2nd calendering roller 2 by feeding mechanism. Two calendering rollers of the application are connected with two servo motor transmissions respectively, and rotate under the drive of servomotor, due to being in transmission connection as conventional techniques means of the prior art between calendering roller and servomotor, therefore its concrete mode of connection and structure do not repeat them here.
Exert pressure mechanism 7 for calendering roller is applied pressure, exert pressure on the bearing position laying respectively at calendering roller two ends, owing to calendering roller is in the course of exerting pressure of bigger pressure (being greater than 3T), roll surface can produce the phenomenon of Light deformation, causes the lithium film rolling out to there will be the thin phenomenon in thick middle, two ends. In order to overcome this kind of phenomenon, the first calendering roller 1 and the 2nd calendering roller 2 of the application are cambered surface roller, and the centre rolling roller exactly is big, and small in ends, whole roll surface is curved.
Lithium band is rolled into lithium film by calendering roller under the exerting pressure of mechanism 7 of exerting pressure, and lithium film is attached on barrier film.

Owing to the size exerted pressure also is the key element determining calendering lithium film quality, the application adopts the size that closed-loop control exerts pressure, and make to exert pressure steadily operates in very little scope. Concrete, controller (not shown) is to setting one preset value of exerting pressure, actual exerting pressure responded to by pressure transmitter 72, exert pressure if actual and it is greater than or less than preset value, controller sends the pressure that instruction regulates oil cylinder 71 fuel feeding, thus reaches, by changing the output pressure of oil cylinder 71, the relative equilibrium exerted pressure.
Frame is also provided with guide deflection sheave 300 and lower guide deflection sheave 400, upper guide deflection sheave 300 and lower guide deflection sheave 400 points of upper and lowers being located at two bearing bracket 20, and for clamping the upper-lower position of two bearing bracket 20. Owing to two bearing bracket 20 can be subject to the very big power of radial effect up and down in calender line, if just by guide pillar (not shown) by power, not only can damage guiding part, nor it is stable, the effect of upper and lower guide deflection sheave be exactly allow two bearing bracket 20 move left and right flexibly while, bigger radial force can be born. In the present embodiment, the 2nd calendering roller 2 is pressure roller.
Being formed with the working clearance for rolling lithium band between first calendering roller 1 and the 2nd calendering roller 2, owing to the supplied materials thickness of lithium band has difference, the required working clearance is not identical yet, therefore the size of working clearance just seems particularly important when calendering force is constant.

Preferably, one end of the 2nd oblique block 56 is provided with limited block (non-label), to limit the displacement in the horizontal direction of the 2nd oblique block 56, the 2nd oblique block 56 can only be moved up and down. One end of 3rd oblique block 57 is fixed on the upper surface of the 2nd oblique block 56, the other end of the 3rd oblique block 57 is embedded between the first calendering roller 1 and the 2nd calendering roller 2, and be slidably connected with the 4th oblique block 58, the 3rd oblique block 57 is fixed on the 2nd oblique block 56 and follows the 2nd oblique block 56 and move up and down. 4th oblique block 58 is fixed on the first bearing support 10 or two bearing bracket 20, the junction of the 3rd oblique block 57 and the 4th oblique block 58 is provided with scarp, 3rd oblique block 57 makes the 4th oblique block 58 move left and right in moving up and down, thus changes the size of working clearance between the first calendering roller 1 and the 2nd calendering roller 2.
Preferably, in order to reduce between the 3rd oblique block 57 and the 4th oblique block 58, and the 3rd oblique frictional force between block 57 and bearing support, it is to increase trimming precision, two thrust surfaces at the 3rd oblique block 57 are provided with two row's rollers 59.
