Detailed description of the invention
Fig. 1 shows the Novel coating machine coating part construction profile that this utility model provides.As can be seen from the figure Novel coating machine, including the portion that unreels being sequentially connected, coating part, winding portion；Described coating part includes slurry tank baffle plate 3, paint roller 2 and back flow roll 1；Described slurry tank baffle plate 3 is connected with the described portion of unreeling, and described slurry tank baffle plate 3 is connected with described paint roller 2, and described back flow roll 1 is connected with described winding portion, and described back flow roll 1 is cylindrical structure with described paint roller 2, and described back flow roll 1 is tangent with described painting 2 roller；Described slurry tank baffle plate 3 is planar structure, described slurry tank baffle plate is also arranged above and the puddler 4 of described slurry tank baffle plate 3 plane parallel, one end of described puddler 4 is connected with cylinder 7, in described cylinder 7 mobilizable embedding cylinder slide slot 8, the bearing of trend of described cylinder slide slot 8 is parallel with described slurry tank baffle plate 3.Described cylinder 7 is Rodless cylinder.During production, layers of foil 10 enters from the portion of unreeling, and the place tangent from paint roller and back flow roll passes, and coating is stored within slurry tank, and back flow roll rotates and drives paint roller to rotate together, and when paint roller rotates, surface speckles with slurry, and layers of foil is just coated in layers of foil through these slurries of paint roller.Due to action of gravity, slurry is understood some and is settled, and this can cause product quality to be deteriorated.The puddler that the cylinder designed by this utility model is driven is stirred significantly improving slurry Deposition Situation.
It is seen also in fig. l that be additionally provided with the motor 5 being detachably connected with described cylinder 7 between described cylinder 7 with described puddler 4, described motor 5 is direct current generator.Described puddler 4 is connected with described motor 5.Puddler can also be arranged on motor, then motor is arranged on cylinder.Described cylinder 7 is connected by hook-shaped connecting plate 6 with described motor.As it is shown in figure 1, hook-shaped connecting plate 6 is the adapter of a bending, side looks as a triangle lacking a limit.Devices different for both direction can be coupled together by hook-shaped connecting plate 6.Here it is not necessarily to by hook-shaped connecting plate, as long as it is the most permissible to play structure cylinder and motor coupled together.
The most described motor 5 drives described puddler 4 to rotate.Motor 5 is internal can be rotated, and drives puddler 4 to rotate together, carries out the stirring of various dimensions.
Fig. 2 is the Novel coating machine coating part plan structure figure that this utility model embodiment provides.The most described cylinder 7 drives described motor 5 and described puddler 4 to move back and forth along described slurry tank baffle plate 3 plane.Making laterally or longitudinally straight line without bar connection cylinder to move back and forth, direct-flow small motor makees continuous rotary motion；The two combines and makes puddler mixing effect more preferable.Cylinder 7 described in Fig. 2 drives described motor 5 and described puddler 4 laterally to move back and forth along described slurry tank baffle plate 3 plane.But can also be designed to described cylinder drives described motor and described puddler longitudinally to move back and forth along described slurry tank baffle plane.
It can also be seen that one end that described puddler 4 is not connected with motor 5 is provided with stirrer paddle 41 from Fig. 1.The design of stirrer paddle 41 adds stirring area, and mixing effect is more preferable.Stirrer paddle stretches into the slurry liquid level less than 9 of hopper, close to paint roller outer radius, does not stops to make horizontal straight line and moves back and forth and continuous rotary motion, prevent uncoated slurry from settling.
The Novel coating machine disposed slurry using this programme to provide is evenly coated in layers of foil by paint roller, the pole piece obtained is distributed before intersecting at the many that is substantially evenly distributed, pole piece original both sides thickness is 10-19um with middle pole piece thickness difference, after using this device, the thickness difference in the middle of the thickness on pole piece both sides and pole piece reduces to 2-5um.The better quality of the lithium ion battery obtained.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
