[0026] Please refer to Figures 1-4 The adjustable baffle defoaming equipment for the roll coating type coating machine trough provided by the present application comprises a trough body 1 and a plate roller body 2, the plate roller body 2 is arranged above the trough body 1 and partially immersed in the slurry in the trough body 1, a defoaming baffle 3 extending along the length direction of the plate roller body 2 is arranged in the trough body 1, the defoaming baffle 3 is arranged obliquely on the side of the plate roller body 2 away from the slurry, the top of the defoaming baffle 3 is close to the plate roller body 2 and extends above the liquid surface, a gap for the slurry to pass through exists between the top end of the defoaming baffle 3 and the plate roller body 2, and an adjusting mechanism 5 is further arranged on the trough body 1, the adjusting mechanism 5 is used for driving the defoaming baffle 3 to translate along the width direction of the trough body 1, so as to adjust the gap size between the top end of the defoaming baffle 3 and the plate roller body 2. The adjustable baffle defoaming equipment provided by the present application realizes coating processing when the product passes through the plate roller body 2 and the plate roller body 2 rotates to adhere and drive the slurry in the trough body 1 to the product.

[0027] As shown in the drawings of the description Figure 4As shown, the solid arrow in the figure is the rotating direction of the plate roller body 2, and during the rotation of the plate roller body 2, the top end of the defoaming baffle 3 can scrape the slurry outside the plate roller body 2 evenly and break the surface bubbles to achieve defoaming, thereby avoiding bubbles adhering to the product to affect the uniformity of coating and effectively improving the product coating quality. In addition, the gap between the top end of the defoaming baffle 3 and the outer wall of the plate roller body 2 allows the slurry of a certain thickness to pass through, and the upper end of the defoaming baffle 3 can scrape the slurry attached to the plate roller body 2 flat and scrape away the excess thickness of the slurry, so that the thickness of the slurry coated on the product is consistent, thereby improving the uniformity of the product surface coating thickness.
