[0032] Working principle: First, place the pathological test paper main body 43 at the middle position on the top of the lower coating seat 2, then start the third motor 30 to lower the upper coating seat 14, so that the first same-side moving groove 4 and the second moving groove 21 are attached and communicated. Then start the second motor 26, so that the L-shaped plate 28 and the vertical plate 29 drive the front and rear movable plates 22, the connecting plate one 23, the connecting plate two 24, the connecting plate three 25, the second lead screw 33 and the third motor 30 to move reversely, so that the relative sides of the front and rear connecting plates three 25 and the front and rear sides of the pathological test paper main body 43 are on the same horizontal line, restricting the range of the pathological test paper main body 43, while the connecting plate one 23, the connecting plate two 24 and the connecting plate three 25 restrict the coating ranges of the first coating roller 9 and the second coating roller 18, making the coating range consistent with the width of the pathological test paper main body 43. Then move the pathological test paper main body 43 to the right, and start the first motor 7 to reversely rotate the first gear 6 and the second gear 17. While facilitating the conveyance of the pathological test paper main body 43, the first coating roller 9 and the second coating roller 18 coat the upper and lower sides of the pathological test paper main body 43. After the coating is completed, the pathological test paper main body 43 enters between the two heating boxes 40 and is heated by the upper and lower heating wires 42 to dry and solidify the pathological test paper main body 43. When only one side needs to be coated, the upper coating seat 14 can be moved upward, the first gear 6 and the second gear 17 are not engaged, and the first motor 7 is started to coat the bottom of the pathological test paper main body 43 with the first coating roller 9.
