Along the direction that alkali metal cathode coiled material moves, inclined third encloses plate gradually downward, and the side that third encloses the lowest part of plate also connects
It is connected to cuboid cavity, the height after height and alkali metal cathode the coiled material folding of cuboid cavity matches and it is located at alkali
Two sides on metal negative electrode coiled material moving direction are open so that alkali metal cathode coiled material passes therethrough, therefore works as alkali metal
When cathode coiled material passes through from the folding device, first under the action of two piece of first enclosing plate spacing becomes narrow gradually, make coiled material two
A edge gradually scrolls up, and with the movement of coiled material, the height rolled is higher and higher, then reaches what the second enclosing plate surrounded
It after region, is tilted gradually downward since the third at top encloses plate, alkali metal cathode coiled material encloses coiled sheet by first
The part got up gradually is pressed into the horizontal direction, and with the movement of coiled material, is pressed in horizontal direction on coiled material
Part is increasingly longer, when then reaching cuboid cavity the edge with certain length of the coiled material be pressed into it is rectangular
The contour position of body cavity just completes the automatic folding of alkali metal cathode coiled material by carrying out roll-in again after cuboid cavity
It is folded, it can be seen that, the automatic coating which can be realized alkali metal cathode coiled material folds coiledization preparation, without artificial behaviour
Make, so as to greatly improve production efficiency.
In a specific embodiment, first the enclosing plate that plate 301 is rectangular shape is enclosed, in this case,
Coiled material can be moved forward smoothly without having more obstruction, and certainly this first, which encloses plate 301, has certain radian
It is also possible, it is not defined herein, as long as not influencing the forward movement of coiled material.
In another specific embodiment, it is trapezoidal enclosing plate that the second enclosing plate 302, which is section, in this shape
It encloses in plate, longer bottom edge is used to be connected with the first enclosing plate, and shorter top margin is used to connect with cuboid cavity 304
It connects, and its bevel edge is used to enclose plate 303 with third and be connected, right-angle side is located at bottom, and coiled material is locating for this right-angle side
Plane on move forward, above-mentioned longer bottom edge, shorter top margin and bevel edge and other enclose between plate are gapless
Connection, can guarantee being normally carried out for folding work in this way, advantageously ensure that the efficiency of folding work is sufficiently high.
In another specific embodiment, third encloses the enclosing plate that plate 303 is preferably rectangular shape, from Fig. 2
It can be seen that it is arranged diagonally downward, and this makes it possible to which the edge of coiled material is gradually suppressed horizontally, such transition effect
Fruit is relatively good, can preferably guarantee that folding work is gone on smoothly, this is only a preferred embodiment certainly, in fact, can be with
The third is set according to specific needs and encloses plate 303 with certain radian, is not also defined herein.
In one more specific embodiment, the height of cuboid cavity 304 can be 0.1 micron to 200 microns, this height
Degree is matched with the coil thickness for specifically wanting to fold out, this all will be understood by those skilled in the art.
Specifically, it is four points of alkali metal cathode web width that two second horizontal distances enclosed between plate, which can choose,
One of to 3/4ths, this can all set according to actual needs, such as in a most commonly used scheme, being should
Horizontal distance between second enclosing plate is set as the half of web width, and there is a quarter on such coiled material both sides respectively
Width folds, and is just overlapped with the width segments of intermediate unfolded half, just by coating after folding in this way
All it is folded in inside coiled material.
In order to further enhance working efficiency, all of plate can also be enclosed in the bottom margin of the first enclosing plate, third
At least one edge is provided with chamfering in edge and top edge in cuboid cavity and lower edge, which is preferably
45 ° of chamferings, but it is not limited to this parameter, it can also be other non-45 ° of chamferings, and the shape of chamfering can be arc
Face or plane, also do not limit here, as long as can be conducive to the folding in coiled material moving process.
Moreover, the quantity of above-mentioned folding device 3 can also be any amount in 2 to 10 other than being 1,
That is it can be folded by more, to obtain the alkali metal cathode coiled material with more coatings, to meet difference
Demand.
In addition, the second rolling device is also provided between heating device 2 and folding device 3 in above equipment, this
Sample first carries out a roll operation before coiled material enters folding device 3, preferably to guarantee its surfacing, folds effect in this way
Rate can be higher, and the probability for folding failure is further decreased.
A specific example is illustrated by taking Fig. 3 as an example below, Fig. 3 is that a serialization provided by the present application prepares alkali
The schematic diagram of the specific example of the equipment of metal negative electrode coiled material, from the point of view of coiled material moving direction, which successively includes transfer roller
401, coatings tank 402, applicator roll 403, transfer roller 404, transfer roller 405, heating device 406, transfer roller 407, roll-in roller 408,
Transfer roller 409, folding device 410, transfer roller 411, roll-in roller 412, the effect of each transfer roller therein are guidance alkali metal
Coiled material enters each device and is processed, and alkali metal cathode coiled material enters process by transfer roller 401, brings coating by applicator roll 403
Coating in slot 402 is coated coiled material, and heating device 406 is entered after transfer roller 404 and transfer roller 405, passes through
After the drying operation of heating device 406, a pair of rolls pressure roller 408 is entered by transfer roller 407 and carries out a roll-in, it is good by coiled material
Good ductility is mutually compound by mechanical force with coating material by it, passes through one or more groups of foldings later using transfer roller 409
Stacking device 410 carry out repeatedly fold again via transfer roller 411 enter roll-in roller 412 carry out roll-in after, complete alkali metal cathode
The preparation of coiled material.
