The inner space 1240 of main body 1230 possesses first side 1241, second side 1242, the 3rd side 1243.First Side 1241 is the face that outlet 1250 is formed with the face of the inner space 1240 of main body 1230.I.e., first side 1240 is With outlet 1250 so that electrode slurry has the face of outlet from the inner space 1240 of main body 1230 to the outside formation discharged. Even if the inner space 1240 of main body 1230 does not have rectangular shape, it is also possible to determine first side 1241 with same principle. The face that internally space 1240 is connected with outlet 1250 is first side 1241.Second side 1242 is internally space 1240 Face in the face opposed with first side 1241 be second side 1242.That is, second side 1242 is located at first side 1241 Opposition side.As shown in figure 5, being not necessarily connected with supply mouth 1210 in second side 1242.Supply mouth 1210 and second side 1242 it is specified unrelated.Second side 1242 determines with the relativeness of first side 1241.3rd side 1243 is from The face that two side faces 1242 extend to first side 1241.The internally face middle finger in addition to upper side and bottom surface in space 1240 Fixed 3rd side 1243.If the face by the side for forming inner space 1240 is the side of inner space 1240, at these The 3rd side 1243 is determined in side.3rd side 1243 is not necessarily a face.3rd side 1243 can be two Side above.
Fig. 3 shows the side of the inner space 1240 that the extrusion coated machine part 1290 of slit is arranged on main body 1230 Method.The extrusion coated machine part 1290 of slit is inserted in into master after main body 1230 is separated into into upper mould 1231 and lower mould 1233 The inner space 1240 of body 1230, and with reference to upper mould 1231 and lower mould 1233.Can be extrusion coated by slit in this way Machine part 1290 is arranged in inner space 1240.On the contrary, slit extrusion can also be removed from inner space 1240 applying Cloth machine part 1290, so as to the extrusion coated machine part 1290 of slit be torn open from the extrusion coated machine of electrode production slit Remove.
With reference to Fig. 5 to Fig. 8, the slit extrusion coated machine inclined plane of part 1290 is from second side 1240 to the 3rd side Face 1243 inclines.The extrusion coated machine part 1290 of slit is to reduce in second by the inner space 1240 of main body 1230 Region that the electrode slurry that the turning that side 1242 and the 3rd side 1243 are formed occurs is stagnated and arrange.Due to electrode slurry The side of outlet 1250 is directed to by inclined plane, so as to electrode slurry does not stagnate in the second side 1242 of inner space 1240 With the turning side between the 3rd side 1243.If electrode slurry flows into the turning between the side 1243 of second side 1242 and the 3rd During side, displacement is elongated, and the amount of the electrode slurry poured in from rear side is little with power, so as to stagnate.Therefore, inclined plane Prevent electrode slurry from flowing into the turning between the side 1243 of second side 1242 and the 3rd at the very start, to eliminate stagnant areas. Now, in order to prevent electrode slurry from the extrusion coated insertion site of machine part 1290 of slit or upper mould 1231 and pad 1232 And the binding site gap leakage between lower mould 1233, it is preferable that in a sealing fashion with reference to these gaps.
The extrusion coated machine part 1290 of slit can be positioned only between the side 1243 of second side 1242 and the 3rd Side in turning, it is also possible to be separately positioned on the left and right sides centered on supply mouth 1210.Even if being positioned only at side, also have Reduce the effect of stagnant areas ratio, but be provided in its effect during both sides and further improve.
The extrusion coated machine part 1290 of slit can be stereochemical structure, i.e. with the first face as inclined plane 1291 second faces 1292 corresponding with second side 1242 and being supported by second side 1242 and with the correspondence of the 3rd side 1243 And the 3rd face 1293 supported by the 3rd side 1243.Wherein, the extrusion coated machine part of slit for particularly illustrating in Fig. 3 1290 is the structure of triangle post shapes.Now, the first face 1291, the second face 1292 and the 3rd face 1293 are in triangle post shapes Constitute trequetrous each side.The extrusion coated machine of slit forms inclined plane, slit with first face 1291 of part 1290 Second face 1292 of extrusion coated machine part 1290 faces with the second side 1242 of inner space 1240, and slit extrusion is applied 3rd face 1293 of cloth machine part 1290 faces with the 3rd side 1243 of inner space 1240.Now, with upper mould 1231 The extrusion coated machine of slit of the parallel plane cutting section shape triangular in shape of part 1290.
When the extrusion coated machine part 1290 of slit is triangle post shapes, slit extrusion coated machine part 1290 The second face 1292 extended with the side end in the first face 1291 of part 1290 from the extrusion coated machine of slit and formed, slit The extrusion coated machine of formula is with the 3rd face 1293 of part 1290 from the first face 1291 of slit extrusion coated machine part 1290 End side extends to the second face 1292 of the extrusion coated machine part 1290 of slit and is formed.Thus, the first face 1291, Second face 1292 and the 3rd face 1293 form three sides of the extrusion coated machine of slit with part 1290 of triangle post shapes. Second face 1292 is intersected with the 3rd face 1293 and forms turning, the turning between the second face 1292 and the 3rd face 1293 be set to Turning correspondence between the side 1243 of second side 1242 and the 3rd.Due to the turning of three-legged structure and turning for inner space 1240 Angle correspondence such that it is able to more firmly supported.It is further possible to firmly fix, to prevent electrode slurry from oozing from gap Leakage.
But, slit extrusion coated machine part 1290 is in not necessarily the shape of three-legged structure.As long as slit is squeezed Go out coating machine part 1290 with the first face, the second face and the 3rd face, section can also be other figures of non-triangular. Even the structure of corner post shapes, as long as corresponding with second side 1242 and by second with the first face as inclined plane Side 1242 support the second face and with the 3rd face that is corresponding and being supported by the 3rd side 1243 of the 3rd side 1243, just belong to The scope of the present invention.
With reference to Fig. 3, Fig. 7 and Fig. 8, in the face for forming the inner space 1240 of main body 1230, inside bottom surface 1260 is formed For the outside for tending to the inner space 1240 from the position for being connected with the supply mouth 1210 gradually rolls upwards oblique.It is this Structure can make the angle change that the 3rd side 1243 of the inner space 1240 of main body 1230 is formed with inside bottom surface 1260 big.When When 3rd side 1243 is less with the angle that inside bottom surface 1260 is formed, it is possible in the 3rd side 1243 and inside bottom surface 1260 Between turning occur electrode slurry stagnation behavior.Become by the angle for being formed the 3rd side 1243 and inside bottom surface 1260 Greatly, contribute to making corner of the electrode slurry between the 3rd side 1243 and inside bottom surface 1260 more gently increase.This When, can further alleviate electrode slurry stagnation behavior.
The volume ratio of stagnant areas can be represented with numerical value according to the extrusion coated physical dimension of machine part 1290 of slit The degree of reduction.From inner space 1240 with the plane cutting main body 1230 vertical with the width D1 of outlet 1250 when It is vertical that the inclined plane of the extrusion coated machine part 1290 of slit for being formed extends to the sectional area of the first side 1241 During to sectional area, on the basis of the ratio of the longitudinal cross-section product, it can be observed that according to the extrusion coated machine part of slit The degree that stagnant areas are reduced after 1290 size setting.Illustrated by specific example using longitudinal cross-section product ratio as The experimental result that benchmark is carried out.

With reference to Figure 18 to Figure 19, example 4 is to be not provided with the extrusion coated machine of slit in the inner space 1240 of main body 1230 to use Experimental result during part 1290.Due to being not provided with the extrusion coated machine part 1290 of slit, thus example 4 have as than Compared with the meaning of example.In this experiment embodiment 4, the flow velocity of electrode slurry is for the volume ratio of the stagnant areas of below 0.1mm/s 11.18% (cumulative volume is 619.3mL, and stagnant areas volume is 69.2mL).Figure 20 is in the extrusion coated machine of slit of example 4 The velocity profile of portion's interior volume.Stagnant areas and VELOCITY DISTRIBUTION can be determined by constant speed line.Slit extrusion is applied The standard deviation of the mean value of the rate of discharge of cloth machine outlet 1250 is 1.89%.
Example 5
Figure 21 be in the interior shape of the extrusion coated machine of slit of the extrusion coated machine part of slit is provided with except The stereogram of the shape of the remainder outside part shared by the extrusion coated machine part of slit, Figure 22 is illustrated in Figure 21 The top view of shape.
With reference to Figure 21 and Figure 22, example 5 is the experimental result of the extrusion coated machine of electrode production slit, in figure 21 In the shape 1350 for illustrating, if with the 3rd side 1243 of the inner space 1240 of main body 1230 closest to when longitudinal cross-section product be A, with the central part of the inner space 1240 of main body 1230 closest to when longitudinal cross-section product for B when, A is the 10.7% of B.Now, As the inclination angle that the extrusion coated machine of slit is formed with the inclined plane in the first face 1291 of part 1290 with second side 1242 For 21.8 degree.
Now, the flow velocity of electrode slurry is that 3.78% (cumulative volume is for the volume ratio of the stagnant areas of below 0.1mm/s 396.3mL, stagnant areas volume is 15.0mL).If be described below be not provided with the extrusion coated machine part of slit 1290 comparative example, when i.e. example 4 compares, it can be observed that, the volume of stagnant areas the volume ratio of stagnant areas is reduced, i.e., Than being reduced to 3.78% from 11.18%.Figure 23 is the velocity profile in the extrusion coated machine inner space of slit of example 5. Stagnant areas and VELOCITY DISTRIBUTION can be determined by constant speed line.
In example 5, it is in the standard deviation of the mean value of the rate of discharge of the extrusion coated machine outlet 1250 of slit 2.19%.Compare with the comparative example for being not provided with the extrusion coated machine part 1290 of slit, the i.e. example 4 being described below When, the standard deviation of the mean value of rate of discharge is changed into 2.19% from 1.89%.This explanation, relative to export center, sidepiece Flow exceedes allows a reference value, it is meant that thickness evenness is reduced to below a reference value when electrode slurry is coated into metal forming. Although as a result, the situation of example 5 is to reduce stagnant areas body by arranging the extrusion coated machine part 1290 of slit Product, but flow deviation is exacerbated, cause coating quality to decline.
Figure 24 by bar shaped illustrate in example 1 to example 5 it is various in the case of stagnant areas volume ratio.As above institute State, the ratio in example 1 is 9.78%, the ratio in example 2 is 7.48%, and the ratio in example 3 is 4.81%, in example 4 Ratio be 11.18%, the ratio in example 5 be 3.78%.As can be seen that in addition to comparative example 4, from example 1 to example 5 Order, its effect is more and more significant.By this result it is recognised that the extrusion coated machine part of set slit The ratio of 1290 longitudinal cross-section product is less, and the volume ratio of stagnant areas is less.It can be seen that minimum in sectional area ratio The decrement of stagnant areas volume ratio is maximum in example 5.
Figure 25 is in the case of various in example 1 to example 5, according to the outlet from outlet centre distance width Relative discharge distribution curve map.Its display, example 1, example 2 be not provided with the extrusion coated machine part 1290 of slit The flow distribution curve of example 4 is almost consistent.And, by the flow distribution curve of example 3 that the ratio of sectional area is 23.0% When being compared with example 4, the flow distribution curve of example 3 does not deviate considerably from the curve of example 4, illustrates almost identical song Line number value.This explanation, the situation of example 1 to example 3, relative to the feelings for being not provided with the extrusion coated machine part 1290 of slit Condition, the flow distribution in the exit after the extrusion coated machine part 1290 of slit is arranged is not apparent from change, that is, apply thickness The constancy of degree is not apparent from reducing.But it is recognised that relative to example 4, the flow deviation of example 5 is big.The outlet of example 5 The standard deviation of the mean value of 1250 rate of discharge is 2.19%, and the slurry flow deviation that exit spues is held beyond quality Perhaps a reference value.Thus, it is possible to say, although the situation of example 5 is reduced by arranging the extrusion coated machine of slit with part 1290 Stagnant areas volumes, but flow deviation is exacerbated, cause the coating quality to reduce.
Based on the above it is recognised that with the plane cutting vertical with the width of outlet, i.e. first direction In the sectional area for extending to first side from inclined plane formed during portion space 1240, so that closest to during three sides Sectional area be closest to inner space 1240 central part when sectional area 23.0% to 53.7%, i.e., sectional area A for cut When the mode of the 23.0% to 53.7% of area B is arranged on incline structure inside the extrusion coated machine of electrode production slit, It is bad so as to reduce the caused coating of stagnation by suppressing electrode slurry stagnation behavior inside coating machine, and keep The extrusion coated machine exit uniform flow distribution of slit.
Additionally, having using the method for angle, according to the slit extrusion coated machine size of the structure of part 1290, numerical value is used Represent the degree that the volume ratio of stagnant areas reduces.The experimental result of Comprehensive example 1 to example 5, when the extrusion coated machine of slit When the angle of inclination formed with the inclined plane of part 1290 and the second side 1242 of main body is 2.8 degree to 16.7 degree, pass through Reduce and occur inside coating machine electrode slurry stagnation behavior, it is bad so as to reduce the caused coating of stagnation, and keep slit The extrusion coated machine exit uniform flow distribution of formula.

Figure 28 is the exploded perspective view of the electrode production that is related to of the third embodiment of the present invention extrusion coated machine of slit, Figure 29 is only to illustrate that the extrusion coated machine use of the slit arranged inside the extrusion coated machine of electrode production slit of Figure 28 can The stereogram of dynamic component, Figure 30 is the assembling stereogram of the electrode production that illustrates in Figure 28 extrusion coated machine of slit, but, For convenience's sake, the pad (shim) illustrated in Figure 28 is eliminated in the assembling figure of Figure 30.Figure 31 is illustrated in Figure 30 The electrode production top view of the extrusion coated machine of slit, Figure 32 is that the electrode production illustrated in Figure 30 is extrusion coated with slit The side view of machine, Figure 33 is the rearview of the electrode production that illustrates in Figure 30 extrusion coated machine of slit.
Below, extruded with slit illustrating the electrode production that the third embodiment of the present invention is related to reference to Figure 28 to Figure 33 Coating machine.
Identical with above-mentioned prior art, the electrode production that the third embodiment of the present invention is related to is extrusion coated with slit Equipment is standby:Supply mouth 3210, for electrode slurry to be supplied into machine extrusion coated to slit;Main body 3230, with inner space 3240, the inner space 3240 connects for housing electrode slurry with supply mouth 3210;And outlet 3250, for from master Body 3230 to outside metal forming discharges electrode slurry.Main body 3230 has upper mould 3231, pad 3232 and lower mould 3233.Row Outlet 3250 has the shape of Bao Erkuan, to make electrode slurry diffusion coat in metal forming.From the supply of supply mouth 3210 Electrode slurry passes through outlet in the inner space 3240 of main body 3230 towards after the width D1 diffusions of outlet 3250 3250 discharge.It is preferred that, electrode slurry is discharged in the whole region of outlet 3250 with uniform speed and thickness.Slit is extruded The mold 3270 of coating machine possesses above-mentioned supply mouth 3210, main body 3230 and outlet 3250.The 3rd of the present invention is real Apply the extrusion coated machine of electrode production slit that example is related to and be also equipped with the extrusion coated machine movable member 3300 of slit, this is narrow The extrusion coated machine movable member 3300 of seam is arranged on the inner space 3240 of main body 3230 in removable mode, for Inner space 3240 is formed selectively inclined plane.The extrusion coated machine of slit has inclined plane with movable member 3300, and this inclines Inclined-plane internally space 3240 be used for leading electrode slurry flowing.Inclined plane can be with the flowing of leading electrode slurry, so as to electricity Pole slurry does not stagnate in the corner part inside the extrusion coated machine of electrode production slit.
By this way, it is further equipped with the extrusion coated machine movable member 3300 of slit such that it is able to relative to reduce The region that electrode slurry is stagnated in the inner space 3240 of main body 3230.
With reference to Figure 28 and Figure 30 to Figure 32, the inner space 3240 of main body 3230 possesses first side 3241, the second side Face 3242, the 3rd side 3243.First side 3241 is to be formed with outlet in the face of the inner space 3240 of main body 3230 3250 face.I.e., first side 3241 is with outlet 3250 so that electrode slurry is from the inner space 3240 of main body 3230 There is the face of outlet to the outside formation discharged.Even if the inner space 3240 of main body 3230 does not have rectangular shape, it is also possible to First side 3241 is determined with same principle.The face that internally space 3240 is connected with outlet 3250 is first side 3241.
Second side 3242 is face opposed with first side 3241 in the face in space 3240 internally.That is, second side 3242 opposition sides for being located at first side 3241.
3rd side 3243 is the face extended from second side 3242 to first side 3241.Except inner space 3240 The 3rd side 3243 is determined in face outside upper side and bottom surface.If being internal empty by the face of the side for forming inner space 3240 Between 3240 side when, in these sides determine the 3rd side 3243.
Figure 28 is the side that the extrusion coated machine movable member 3300 of slit is arranged on the inner space 3240 of main body 3230 The schematic diagram of method.By the extrusion coated machine movable member of slit after main body 3230 is separated into into upper mould 3231 and lower mould 3233 3300 are inserted in the inner space 3240 of main body 3230, and with reference to upper mould 3231 and lower mould 3233.In this process, handle component 3390 bullports 3294 by being formed on lower mould 3233 are exposed to the outside of coating machine mould from inner space 3240.And And, lateral space 3246 is formed with lower mould 3233, the lateral space 3246 is used to provide insertion and travelling slit formula extrusion The coating machine space of the end of the rear board member 3350 of movable member 3300.
The extrusion coated machine movable member 3300 of slit can be arranged in inner space 3240.On the contrary, also may be used To remove the extrusion coated machine movable member 3300 of slit from inner space 3240, can so as to the extrusion coated machine of slit be used Dynamic component 3300 is removed from electrode production with the extrusion coated machine of slit.
The extrusion coated machine of slit has cylinder component 3320, rear board member 3350, side plate parts with movable member 3300 3370 and handle component 3390.Cylinder component 3320 is fixed in main body, to prevent being rotated and straight line fortune It is dynamic to wait movement.Afterwards board member 3350 is the part that can be rotated centered on cylinder component 3320.The one of board member 3350 afterwards End is rotatably engaged in cylinder component 3320, and the other end to the 3rd side 3243 extends.
In this third embodiment, rear board member 3350 is in the tabular with front surface 3357 and rear surface 3358.But It is that not necessarily there is tabular.When rear board member 3350 is pivoted about with cylinder component 3320, rear board member 3350 front surface 3357 forms the inclined plane from second side 3242 to the 3rd side 3243.Now, rear board member 3350 Front surface 3357 can be with leading electrode pulp flow.
Afterwards board member 3350 can be only formed in side centered on cylinder component 3320, it is also possible to be formed in both sides.By This, the inclined plane formed by the front surface 3357 of rear board member 3350 can be only formed in one centered on cylinder component 3320 Side, it is also possible to be formed in both sides.Even if also can reduce when inclined plane is only formed in side centered on cylinder component 3320 The phenomenon that inner space electrode size is stagnated, but inclined plane can be obtained into one when the both sides of cylinder component 3320 are respectively formed Walk improved result.
Cylinder component 3320 can be arranged according to the position of supply mouth 3210.Now, inclined plane is with supply mouth 3210 It is centrally formed in both sides.Now, inner space 3240 can have symmetrical shape, so as to electrode slurry can in outlet 3250 More uniformly to discharge, therefore preferably.
Side plate parts 3370 have one end and the other end, and its one end is rotatably engaged in rear board member 3350, separately One end to outlet 3250 extends (discharge direction that electrode slurry is discharged).Side plate parts 3370 are contacted with the 3rd side 3243. Thus side plate parts 3370 are moved along the 3rd side 3243.Move towards outlet 3250, also towards its opposite direction movement.
The extrusion coated machine movable member 3300 of slit possesses handle component 3390, in order to mobile side plate parts 3370.One end of handle component 3390 is connected with side plate parts 3370, direction (electrode slurry of the other end towards second side 3242 The opposite direction that material is discharged) extend.The other end of handle component 3390 is outside by the bullport 3294 being formed on lower mould 3233 Portion extends, thus, it is also possible to which the extrusion coated machine of slit in the internally positioned space 3240 of the external control of coating machine mould is used Movable member 3300.
Handle component 3390 is moved along a straight line by the bullport 3294 being formed on lower mould 3233.When to outlet Side plate parts 3370 are also moved to outlet 3250 during 3250 push handle part 3390.Due to handle component 3390 one end with Side plate parts 3370 connect, so the amount of movement of handle component 3390 is corresponding with the amount of movement of side plate parts 3370.
Figure 34 is that the electrode production illustrated in Figure 30 uses movable with the extrusion coated machine of slit of the extrusion coated machine of slit Part forms schematic diagram during inclined plane, and Figure 35 is the vertical view of the electrode production that illustrates in Figure 34 extrusion coated machine of slit Figure, Figure 36 is the side view of the electrode production that illustrates in Figure 34 extrusion coated machine of slit, and Figure 37 is the electricity illustrated in Figure 34 The pole production rearview of the extrusion coated machine of slit.
The extrusion coated machine of the slit illustrated in Figure 34 to Figure 37 and Figure 30 to Figure 33 is compared, in Figure 34 to Figure 37 Illustrate, the shape that the extrusion coated machine of slit is further moved side plate parts to outlet using handle component along the 3rd side State.
When side plate parts 3370 are moved to the direction of outlet 3250, with reference to the rear plate portion on the one end of side plate parts 3370 The other end of part 3350 is also to the side shifting of outlet 3250.When after board member 3350 the other end to the direction of outlet 3250 move When, because cylinder component 3320 is fixed, therefore rear board member 3350 is pivoted about with cylinder component 3320.Work as back plate When part 3350 is pivoted about with cylinder component 3320, the front surface 3357 of rear board member 3350 is formed from second side The inclined plane of 3242 to the 3rd sides 3243.Identical principle, the extrusion coated machine movable part 3300 of slit formed from Inclined plane of the second side 3242 towards the 3rd side 3243.
The rear board member 3350 of the extrusion coated machine movable member 3300 of slit is formed from second side 3242 to the 3rd The inclined plane of side 3243, this is to reduce the electricity that the turning between the side 3243 of second side 3242 and the 3rd occurs Pole stock settling region.Because electrode slurry is more easily guided to the side of outlet 3250 by inclined plane, therefore electrode slurry The corner between the side 3243 of second side 3242 and the 3rd of inner space 3240 is not stagnated in.
When electrode slurry flows into the turning side between the side 3243 of second side 3242 and the 3rd, because displacement becomes It is long, and the amount of the electrode slurry poured in from rear side is little with power, so as to stagnate.Therefore, inclined plane prevents at the very start electricity Pole slurry flows into the turning between the side 3243 of second side 3242 and the 3rd, to eliminate stagnant areas.
Now, in order to the gap that prevents electrode slurry from being formed from the extrusion coated machine movable member 3300 of slit or on The gap leakage of the binding site between mould 3231 and pad 3232 and lower mould 3233, it is preferable that in a sealing fashion with reference to these Gap.
