Background
The gravity casting grid is easy to have the problem that the downward surface of the polar plate is not tightly coated in the lead plaster coating process, and ribs are exposed. The main reason is that after the grid enters the filling machine head, the conveyor belt at the bottom moves along the same direction with the transverse ribs 3, and when the grid passes through the filling pressing plate main body 1, the lead plaster is filled on the surface of the gravity casting grid through the filling opening 2 under the action of gravity and a filling motor. At this time, because the filling bottom plate below the conveyor belt is a flat steel plate, spaces between the transverse ribs 3 and the vertical ribs 6 of the gravity filling grid and the bottom conveyor belt are small, and lead plaster pressed down from the top is difficult to enter the bottoms of the transverse ribs 3 and the vertical ribs 6, the filling bottom plate is shown in fig. 1, the gravity casting grid (large sheet) is shown in fig. 2, and the gravity casting grid further comprises the plate lugs 4, the frame 5 and the connecting heel 7. The ribs of the polar plate are not covered by lead plaster, the overall strength of the polar plate and the corrosion resistance of the grid are greatly reduced, and the service life of the lead-acid storage battery is influenced.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 3 and 4, an embodiment of a filling bottom plate for improving the double-sided coating effect of a gravity casting polar plate according to the present utility model includes a filling bottom plate body 8, and a groove 9 is formed on the upper surface of the filling bottom plate body 8.
The filling bottom plate main body 8 is a rectangular plate and is made of stainless steel.
The grooves 9 are two groups and are symmetrically distributed on the coating bottom plate main body 8 left and right and respectively correspond to two gravity casting grids to be coated, which are connected with the connecting heel 7 in fig. 2. The number of grooves 9 in each group is 10, and the grooves are parallel to each other and are the same as 10 transverse ribs 3 of the gravity casting grid to be coated.
