Specific embodiment
Below in conjunction with the attached drawing of this specification, presently preferred embodiments of the present invention is further described in detail.
It is the structural representation at a visual angle of coating die head of the invention referring to Fig. 1 to Fig. 3, Fig. 1.Fig. 2 is of the invention
The structural representation at another visual angle of coating die head.Fig. 3 is the structural representation at another visual angle of coating die head of the invention,
Middle upper die head is removed.The present invention proposes a kind of coating machine of electrodes of lithium-ion batteries comprising coating die head 10.The coating
Die head 10 includes upper die head 1, lower die head 2 and agitating device 3.Upper die head 1 and lower die head 2 cooperate, and form discharge port 5 in front end.
The upper die head 1 is fixed in the lower die head 2.The agitating device 3 is installed in the lower die head 2.
The upper die head 1, which is equipped with, adjusts gap 11.Multiple spot is carried out by the width extending direction to the adjusting gap 11
It adjusts, the size of discharge port 5 can be adjusted along the width extending direction of the coating die head 10, it is advantageously ensured that coating thickness
It is uniformly distributed.
It is set in the lower die head 2 there are three rear openings, the feed inlet 21 that horizontally front and back extends.The lower die head 2 is equipped with one
A open top, the hopper 23 that horizontally laterally (i.e. left and right) extends, and positioned at 23 front of hopper an open top,
The dashpot 25 being horizontally laterally extended.Coating sizing-agent is first into hopper 23 by feed inlet 21, the coating in hopper 23
After slurry spill-over comes out, dashpot 25 can be flowed into, after the coating sizing-agent spill-over in dashpot 25 comes out, Cai Huicong discharge port 5 sprays
Painting is gone out, and is applied on the substrate of the pole piece with coating.Preferably, the longitudinal cross-section of the hopper 23 is in inverted ladder shape, front side
Waist is that inclination extends forward and up, and low back is basically perpendicular to the top surface of the lower die head 2.The bottom and top of the hopper 23
