Embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
The embodiment of the present application provides a kind of coating mechanism, and for the painting process of base material 80, base material 80 includes relative
On first face and the second face, the first face and the second face need that slurry is respectively coated, wherein, tape transport direction refers to the sender of base material 80
To.
As shown in figure 1, coating mechanism includes the first coater unit 10 and the second coater unit 30, relative to tape transport direction,
First coater unit 10 and the second coater unit 30 are located at the both sides of base material 80, and the first jet of the first coater unit 10 respectively
Towards the first face, the second face of second nozzle direction of the second coater unit 30.
Above-mentioned coating mechanism, makes the first coater unit 10 and the second coater unit 30 be located at the both sides of base material 80 respectively,
During tape transport, the first 10 pair first of coater unit face is coated, and the second 30 pair second of coater unit face is coated,
Therefore, it is possible to complete to be coated with to the two sides of base material 80 simultaneously during a tape transport, then the slurry on two sides is entered simultaneously again
Row drying.As can be seen that after this coating mechanism is while complete two sided coatings, two sides slurry is dried simultaneously, therefore,
The redrying of one side slurry is avoided, the probability of pole piece season cracking can be reduced as far as possible, so as to improve the quality of pole piece.
Further, the first coater unit 10 can be relative with position with the second coater unit 30, i.e. first jet and second
Nozzle is coated to the region that the first face and the second face are located at same position on base material 80 simultaneously, now, the spray of first jet
Penetrate direction opposite with the injection direction of second nozzle.Alternatively, along tape transport direction, the first coater unit 10 and the second coater unit
30 are staggeredly located, i.e., be pointed to diverse location on base material 80 (refers to the difference along tape transport direction to first jet simultaneously with second nozzle
Position) the first face and the second face be coated, to prevent first module 10 from being caused with second unit 30 during coating
Interact, reduce coating quality.
First coater unit 10 and the second coater unit 30 can be extrusion coating machine or dropping curtain coating machine, can also
The two is different coating machine, and such as the first coater unit 10 is extrusion coating machine, and the second coater unit 30 is dropping curtain coating machine, its
In, in dropping curtain coating machine, in addition to evagination pad, evagination pad can be controlled to the stability of dropping curtain coating machine dropping curtain
System.
Generally, it is extruding especially in the first coater unit 10 or the second coater unit 30 in order to ensure the quality being coated with
During coating machine, coating mechanism also includes the one side back flow roll 50 for being used to transmit base material, one side back flow roll 50 and first jet or second
Nozzle is relative, and support can be provided for base material 80, the quality of coating is further improved.As shown in figure 1, the first coater unit 10 is
Extrusion coating machine, first jet is relative with one side back flow roll 60, base material 80 is located between first jet and one side back flow roll 80, and edge
One side back flow roll 50 outer peripheral face transmission, first jet on the first face with its just to region be coated.
In order to ensure the spreading of base material 80 during coating, coating mechanism also includes single-sided clamp rod 60, single-sided clamp rod 60 and list
Face back flow roll 50 is relative, and base material 80 is located between single-sided clamp rod 60 and one side back flow roll 50, one side back flow roll 50 is pressed from both sides with single-sided clamp rod 60
Tight base material 80.
The injection direction of first jet and the injection direction of second nozzle can be horizontal direction or vertical direction,
Can be other unspecified angles.Usually, the injection direction of first jet elects horizontal direction as, especially in the first coater unit 10
During for extrusion coating machine, to ensure the quality of coating.
The injection direction of second nozzle is vertical direction, now, the second coater unit 30 can for extrusion coating machine or
Dropping curtain coating machine, it is preferable that the second coater unit 30 is dropping curtain coating machine, with using the coating of vertical direction, even at a high speed
During tape transport, the quality of coating also ensure that.
In aforesaid way, the injection direction of first jet is horizontal direction, and the injection direction of second nozzle is vertical direction,
The tape transport of base material 80 can be made more smooth, and path is shorter, reduces the quantity of guide roller, improves the efficiency of coating, saves cost.
Certainly, the injection direction of first jet can also be vertical direction, and the injection direction of second nozzle can also be horizontal direction.
As Fig. 1 gives a kind of preferred embodiment, the injection direction of first jet is horizontal direction, the spray of second nozzle
Direction is penetrated for vertical direction, and the first coater unit 10 is extrusion coating machine, the second coater unit 30 is dropping curtain coating machine, can
Both the path of tape transport had been reduced, the function of double spread can be realized simultaneously again.
The injection direction of first jet be horizontal direction, second nozzle injection direction be the embodiment of vertical direction
In, especially when the second coater unit 30 is blanking coating machine, slurry falls into the second face of base material 80 by gravity, in order to prevent
The pulp flow of vertical direction coating even comes off, and the second coater unit 30 is compared with the first coater unit 10 close to discharge end, i.e. edge
Tape transport direction coating mechanism has a feeding end and discharge end, and base material 80 enters after feeding end, the first coater unit 10 first to its
Simultaneously it is coated, then the second coater unit 30 is coated to its second face again, is finally sent to discharge end.
In order to better ensure that the quality of coating, and coating efficiency is improved, coating mechanism also includes drying device 70, edge
Tape transport direction, drying device 70 close to discharge end, i.e., is coated with single compared with the first coater unit 10 and the second coater unit 30 first
After the coater unit 30 of member 10 and second is coated with, base material 80 is directly dried by drying device 70, and base material 80 is applied by first
After the coater unit 30 of cloth unit 10 and second, it is dried into drying device 70, dried base material 80 sends out discharge end.
In addition, coating mechanism also includes the first charging pump 20 and the second charging pump 40, the first charging pump 20 and the first coating
Unit 10 is connected, and the second charging pump 40 is connected with the second coater unit 30, thinks the first coater unit 10 and the second coater unit
30 provide slurry.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent substitution, improvement etc., should be included within the protection domain of the application.
