Description
Technical field
The invention belongs to metal material combination process field, is related to a kind of compound calender device of lithium band and its method.
Background technology
At present, the composite of battery industry lithium and other metals is constantly extending just in broad development using manor.
But it is reported that the mode of production of composite is in manual patch, by way of simply rolling and then cut out by hand.It is lacked
Putting is：Its operating efficiency and yield rate ratio are relatively low, the guarantee that quality can not be stablized, and product does not have complete standard mark
With no doubt influenceing production cost.
The content of the invention
In view of this, it is an object of the invention to provide a kind of compound calender device of lithium band and its method.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of compound calender device of lithium band, including feed device, roller move calender device and wrap-up, the feed device
Including metal foil unreeling shaft, lithium band unreeling shaft and the PE unreeling shafts set gradually, the lithium band unreeling shaft and PE unreeling shafts are
Two, it is symmetrically arranged at the both sides of metal foil；The feed device and wrap-up also include draw-gear and some auxiliary
Help wheel.
Further, the wrap-up includes jockey pulley, useless PE Scrolls, compound Scroll and overlap Scroll.
Further, it is that wheel is prolonged in multistage roller dynamic pressure that the roller, which moves calender device,.
Further, the wrap-up and roller are additionally provided with calibrator between moving calender device.
Further, the calibrator is laser thickness gauge.
Further, the wrap-up and roller are additionally provided with trimming mechanism between moving calender device.
A kind of compound calendering process of lithium band, metal foil and lithium band are pressed, are used as by PE material unwindings in lithium belt surface
Diaphragm, lithium band is completely cut off and has prolonged directly contacting for wheel with roller dynamic pressure, rolled the multistage roll-in of wheel by rolling, roller dynamic pressures at different levels are prolonged
After wheel pressurizes step by step, the winding of compound winding, useless PE materials and overlap is carried out.
The beneficial effects of the present invention are：
1st, realize automation lithium band and metal foil material it is compound.
2nd, solve the problems, such as and control lithium metal and the viscous of disk roller sticks, can preferably improve the quality of production and efficiency.
3rd, using multistage roll-in, it is more conducive in the technical process of composite, is satisfied with the compactness of composite
It is compound with material tight.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out
Explanation：
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
A kind of compound calender device of lithium band, including feed device, roller move calender device and wrap-up, the feed device
Including metal foil unreeling shaft, lithium band unreeling shaft 2 and the PE unreeling shafts 3 set gradually, the metal foil unreeling shaft of the present embodiment is copper
Paper tinsel unreeling shaft 1, the lithium band unreeling shaft 2 and PE unreeling shafts 3 are two, are symmetrically arranged at the both sides of metal foil；It is described
Feed device and wrap-up also include draw-gear 4 and some auxiliary wheels 5.Wrap-up include jockey pulley 6, useless PE windings 7,
Compound Scroll 8 and overlap Scroll 9.It is that wheel 10 is prolonged in multistage roller dynamic pressure that the roller, which moves calender device,.The wrap-up and roller
Calibrator is additionally provided between dynamic calender device.The calibrator of the present embodiment is laser thickness gauge 11.Wrap-up and roller dynamic pressure are prolonged
Trimming mechanism is additionally provided between device.The present embodiment trimming mechanism is control shearing knife 12.
Copper foil unreeling shaft 1 pulls out copper foil by draw-gear, and lithium band is attached to copper by lithium band unreeling shaft 2 and draw-gear
On the two sides of paper tinsel, then PE thin material is sticked on two faces of lithium band, be copper successively from the inside to surface as the diaphragm of lithium band
Paper tinsel, lithium band and PE films, once complete to extend by the dynamic calender device of roller step by step and compound, farthest avoid lithium with rolling
The viscous of wheel surface sticks, while is more conducive in the technical process of composite, is satisfied with the compactness and material of composite
It is closely compound, material is being sent out by draw-gear, is carrying out trimming with control shearing knife 12, laser thickness gauge measurement is thick
Degree, the winding of compound winding, useless PE materials and overlap is finally carried out, completes lithium band and the combination process of metal foil.
, finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
