Described often cover coating machine all comprises uncoiler, winder, forward dispense tip, reverse dispense tip, the deflector roll 6 carrying battery pole piece 4 transmission and the heating, drying device 3 be made up of in head and the tail tandem many baking ovens, described uncoiler, winder, forward, reverse dispense tip is all arranged at head end or the tail end of heating, drying device 3, described deflector roll about 6 points is two-layer, and to be all located at described heating, drying device inner and extend to tail end by the head end of heating, drying device and extend to described head end by this tail end again, deflector roll 6 by battery pole piece 4 by uncoiler end through forward dispense tip, heating, drying, reverse dispense tip, heating, drying reaches winder end.
Above lower coating machine 1, be provided with this workbench 5 of workbench 5(built by angle bar frame 51 and steel plate also can be floor dividing plate), described upper coating machine 2 to be positioned on workbench 5 and to be fixedly connected with it, and lower coating machine 1 to be positioned under workbench 5 and to fix on the ground.First uncoiler 11 of lower coating machine 1 and the first winder 12 are separately positioned on below and the top of the described workbench 5 of lower coating machine one end; Second uncoiler 21 of upper coating machine 2 and the second winder 22 are separately positioned on below and the top of the described workbench 5 of lower coating machine 1 other end; First forward dispense tip 13 of lower coating machine 1 is between one end of the heating, drying device 3 of described first uncoiler 11 and lower coating machine 1, and the first reverse dispense tip 14 of lower coating machine 1 is between the other end of the heating, drying device 3 of the second uncoiler 21 and lower coating machine 1; Second forward dispense tip 23 of upper coating machine 2 is between one end of the heating, drying device 3 of described second winder 22 and upper coating machine 2, and the second reverse dispense tip 24 of upper coating machine 2 is between the other end of the heating, drying device 3 of the first winder 12 and upper coating machine 2.
Further improvement of the present invention the baking oven of the described heating, drying device 3 of composition is changed into current-sharing baking oven 7(with circulation current-sharing hot air apparatus hereinafter referred to as current-sharing baking oven 7), thus, battery pole piece in heating, drying device 3 is heated evenly in the process run, and, can the coating width of battery pole piece 4 be heightened to 800mm by the 500mm of prior art, improve production efficiency.
The device of heating, drying described in prior art baking oven used is:
1) air inlet is located at the front end face of baking oven, air intake (wind do not heated) is sent in drying channel road through air blast, heater and warm-air pipe by the rear end of baking oven, air draft is blown out by the rear end face of baking oven again, the middle part of drying channel is then in negative pressure state, causes drying in oven passage non-uniform temperature everywhere thus.
2) when heating, drying device is made up of multiple baking oven, then the described air draft of previous baking oven then becomes the described air intake of a rear baking oven, thus, just formed in whole heating, drying device " draught " that one is huge, this not only makes the battery pole piece being arranged in baking oven, under the blowing of described " draught ", jolted or wave and affect uniform drying and the product quality of battery pole piece, and, the heat in baking oven also can be made to be discharged into outside heating, drying device along with described " draught ", in order to keep the heat of baking needed, have to strengthen heating power, improve power consumption, increase cost.
3) due to non-uniform temperature everywhere in the drying channel in baking oven, cause the edge of battery pole piece different with middle rate of drying, edge is dry soon, center dries slow, thus, bring three unfavorable results: one, in order to make battery pole piece zone line bone dry, have no alternative but the speed of service that will reduce battery pole piece coating machine equipment, to lengthen the time of battery pole piece in heating, drying device; They are two years old, dry battery pole piece fringe region comparatively early, to be heated if continue oven dry, easy generation crimping bad phenomenon, processed battery pole piece is wider, and edge-curl phenomenon is more serious, therefore, the coating width of battery pole piece coating machine of the prior art receives restriction, and usually, coating width of the prior art is within 500mm; Its three, because the rate of drying at battery pole piece zone line and edge is asynchronous, the fringe region of fast drying easily produces crimping bad phenomenon.The maximum harm of " crimping " is that easy web-like edge and oven interior mechanism rub, pull, and even base material fracture, the loss at this moment caused is very serious.Produce and interrupt; Open chamber door heat radiation, cooling, artificial rescue tape splicing.Amount of heat loses, and lot of materials is wasted; So when oven structure is constant, for the speed by improving equipment operation and lengthening heating, drying device or the process modification increasing heating power, it is impossible for enhancing productivity.
As shown in Figure 4, face, described current-sharing baking oven 7 rear and front end in energy-efficient battery pole piece unicoater of the present invention is semiclosed, anterior-posterior length is increased to 4 meters by original 3 meters, every platform current-sharing baking oven 7 by the hot blast jet pipe it being at least provided with a through hole, hot air duct 73, heater 74, air blast 75 and return air duct 76 form, wherein, upper drying channel 71 to described current-sharing baking oven 7 supplies the second hot blast jet pipe that the first hot blast jet pipe of hot blast and downward drying channel 72 supply hot blast, the rear and front end of described current-sharing baking oven 7 is arranged at respectively in the mode perpendicular to base material traffic direction, by upper drying channel 71 air draft of described current-sharing baking oven 7 the first return air inlet and be all located at the middle part of described current-sharing baking oven 7 by the second return air inlet of lower drying channel 72 air draft, like this, hot blast is held to intermediate flow by before or after current-sharing baking oven 7, change hot wind flow direction thus, make to be heated evenly everywhere in drying channel, air pressure is impartial, and, again because the rear and front end of current-sharing baking oven 7 is in semi-closed state, can not produce as described " draught " of the prior art in drying channel, decrease thermal loss, temperature is everywhere made again in drying channel to remain on uniformity and in stable state, thus, substantially increase in the middle of battery pole piece 4 and the synchronism of edge rate of drying.
The gas flow of described first hot blast jet pipe of the present invention and the second hot blast jet pipe is more than or equal to the first corresponding return air inlet and the gas flow of the second return air inlet, like this, further increase again the harmony of hot blast in drying channel, further increase in the middle of battery pole piece 4 and the synchronism of edge rate of drying.
In the drying channel of current-sharing baking oven 7 of the present invention, because hot blast is downwards toward return air inlet flowing from battery pole piece 4 dual-side, thus, it is greater than the flowing velocity at battery pole piece 4 zone line in the flowing velocity of battery pole piece 4 dual-side, in order to further improve in the middle of battery pole piece 4 and the synchronism of edge rate of drying, the density that the manhole (also can be the through hole of other shape) on described first hot blast jet pipe and the second hot blast jet pipe is arranged is successively decreased to edge by the center of described jet pipe.
The present invention also the edge of a knife shape tuyere concentrated, makes distributed circular hole tuyere into, and make whole base material wind-engaging even, pressure reduces, and avoids coating surface to blow be uneven.
In the dry run of battery pole piece 4 in heating, drying device 3 of the present invention, the rate of drying of uniformity, greatly reduce the generation of battery pole piece 4 peripheral bead phenomenon, make the present invention both the coating width of battery pole piece 4 can be increased to 800mm, the running speed of equipment can be improved again, thus, enhance productivity, reduce energy resource consumption.
In order to reduce occupation area of equipment, can by upper coating machine 2, the outer shape of the heating, drying device 3 of lower coating machine 1 makes the arch that Open Side Down, namely the middle part of heating, drying device 3 is protruding upward higher than its two ends, the shape of described workbench 5 is also identical with the outer shape of heating, drying device 3, the vertical range on the height point distance work ground of described workbench 5 is 3.5 meters, the vertical height of described heating, drying device 3 is 2.0 meters, its horizontal length is 40 meters, height overall is only 5.5 meters, by upper coating machine 2, arch tendency parallel each other all made by heating, drying device 3 and the workbench 5 of lower coating machine 1, not only space can be made full use of, save land area, great deal of steel (plane platform support is more than arch platform support material) can be saved again, the stable degree of battery pole piece 4 in process can also be improved.
Described apparatus for coating forward dispense tip and reverse coating head device are placed in respectively in the higher operating room of cleanliness factor, this operating room and outdoor seal better, indoor are connected with circulation pure air, so both can ensure crucial painting process environmental sanitation, improve the quality of products, can save again and whole coating machine is placed in dust proof workshop and the unnecessary and huge investment produced, effectively reduce cost.
The conventional equipments such as the switch board that energy-efficient assembled battery pole piece unicoater of the present invention is used and power distribution cabinet, scattering device is in the outside of the heating, drying device 3 of described lower coating machine, and as far as possible near central control room, be equipped with sliding door again, be convenient to installation, maintenance, and, decrease and control interference, also save a lot of cable, coating unit room (referring to the room installing coating head device) only installs the liquid crystal display touch screen that can move forward and backward, and is convenient to monitoring.
The present invention has the following advantages:
1) increase coating and dry length:
Increase and be coated with the best approach that cloth length is raising effect, because dry length to double, when the stoving process time is determined constant, the speed of the equipment operation of baking stage just doubles, also namely the process velocity of battery pole piece 4 just doubles, production efficiency also just doubles, and the investment increased is only the several less expensive current-sharing baking oven 7 installed more, other are worth higher coater head, uncoiler and winder does not increase, namely, when little input, higher income is obtained.
2) coating width is increased:
The length of heating, drying device 3 adds, elongated coated substrate (the Boats of base material and battery pole piece coating, as the aluminium foil of positive plate or the Copper Foil of negative plate) in current-sharing baking oven 7 operation not easily stablize, can vacillate now to the left, now to the right, (changed into the curve of arch by former straight line by described track by change substrate width and the running orbit of base material in current-sharing baking oven 7, improve base material to the adhesive force of deflector roll 6), just can both solve base material traveling comfort, turn improve production efficiency (being obtained by the coating width increasing base material).The effective width of coating machine coating battery pole piece 4 of the present invention can reach 800mm.
Beneficial effect of the present invention:
1) by broadening to 800mm by original 500mm for battery pole piece 4 coating width, within the unit interval, can enhance productivity thus.Actual current-sharing baking oven 7 inner width is 900mm, nominal 800mm, differs from 100 and gives over to base material activity surplus.If running orbit controls well, dead beat of not wafing, production 820 is also out of question.Battery pole piece coating machine production scale of the prior art is little, the oven interior width only 600mm of heating, drying device, due to aforementioned techniques reason, and wind Dutch roll, the most as many as 500mm of battery pole piece 4 coating width.
2) described coating machine heating, drying device 3 often save the length (by original 3 meters be increased to 4 meters) of current-sharing baking oven 7 length than prior art, when the stoving process time is determined, the lengthening of heating, drying device 3, effectively can improve the running process velocity (namely in the unit interval, the battery pole piece 4 of coating increases) of equipment, thus, another improves production efficiency.
3) prior art and the benefit table of comparisons of the present invention are in table 1.
Table 1---prior art and the benefit table of comparisons of the present invention (singly overlapping production line):
As can be seen from Table 1, although single complete equipment power (power consumption) of the present invention comparatively in prior art single complete equipment power add 59%, equipment investment price (cost) adds 43%, and production efficiency is 3.5 times of prior art.
Because the present invention's current-sharing baking oven 7 used has circulation current-sharing hot air apparatus, and the heating, drying device 3 of the heating, drying device 3 of upper coating machine 2 and lower coating machine 1 is superimposed mutually, mutually play insulation effect (namely for the heating, drying device of lower coating machine 1, the heating, drying device 3 of upper coating machine 2 is just as one heat-insulation layer, and the heating, drying device 3 reducing lower coating machine 1 is the heat that distributes of space environment upward; Equally, for the heating, drying device 3 of upper coating machine 2, the heating, drying device 3 of lower coating machine 1 is one heat-insulation layer below it), after described heating, drying device 3 intensification reaches thermal balance, heating power also can decline 30% ~ 40%.
