[0030] Reference Figure 1-Figure 5 The present embodiment provides a fireproof board glue dipping device, comprising a box body 110 filled with glue, a plurality of rotating rollers 130 for contacting the lower surface of the fireproof board 120 are movably arranged in the box body 110, and the bottom of the rotating roller 130 is located below the glue liquid surface, and a plurality of glue coating rollers 140 for contacting the upper surface of the fireproof board 120 are also movably arranged in the box body 110, and the glue coating rollers 140 are all located above the corresponding rotating rollers 130; wherein the glue coating roller 140 comprises an outer cylinder body 141 and an inner cylinder body 142 located inside the outer cylinder body 141, a plurality of support shafts 143 are connected between the outer wall of the inner cylinder body 142 and the inner wall of the outer cylinder body 141, and the outer wall of the inner cylinder body 142 is connected to the outer cylinder body 141. The chamber between the inner walls of the cylinder 141 is filled with glue, and the outer wall of the inner cylinder 142 is connected to a plurality of elastic telescopic mechanisms 144, and the other end of the elastic telescopic mechanism 144 is connected to a stopper 145, and the stopper 145 is connected to a contact ball 146 for contacting the fireproof board 120, and a plurality of glue outlet holes 1411 corresponding to the contact balls 146 are provided on the outer cylinder 141, and the diameter of the contact ball 146 is smaller than the diameter of the glue outlet hole 1411, and the width of the stopper 145 is larger than the diameter of the glue outlet hole 1411, and when the contact ball 146 is not in contact with the fireproof board 120, a part of the contact ball 146 extends out of the glue outlet hole 1411, and the stopper 145 covers the glue outlet hole 1411.

[0031] In this embodiment, during operation, the rotating drum 130 and the glue coating drum 140 are rotated slowly and uniformly, the fireproof board 120 is clamped between the two and transported forward, when the fireproof board 120 moves between the rotating drum 130 and the glue coating drum 140, the glue adhered to the rotating drum 130 is coated on the lower surface of the fireproof board 120, and when the contact ball 146 in the glue coating drum 140 contacts the fireproof board 120, the contact ball 146 is squeezed by the reaction force of the fireproof board 120 and retracted into the glue outlet hole 1411, and the elastic telescopic mechanism 144 also shrinks accordingly, and at this time the stopper 145 also leaves the glue outlet hole 1411, thereby contacting the blocking effect on the glue outlet hole 1411, and the glue in the outer cylinder 141 Water can flow out from the glue outlet hole 1411 and be coated on the upper surface of the fireproof board 120. There are multiple glue outlet holes 1411, which can form a multi-point uniform coating effect. The outer cylinder 141 can then cooperate with the glue flowing out of multiple points to press the glue evenly, thereby realizing the integrated function of automatic glue discharge and pressing of the glue coating roller 140, improving the uniformity of glue coating, and eliminating the need to set up a glue spraying device separately, saving equipment costs. When the contact ball 146 rotates and no longer contacts the fireproof board 120, the elastic force of the elastic telescopic mechanism 144 pushes the block 145 to block the glue outlet hole 1411, thereby preventing the glue from flowing out of the outer cylinder 141 at will and spilling on the fireproof board 120, thereby ensuring the uniformity of coating.

[0033] In this embodiment, when the contact ball 146 is compressed into the glue outlet hole 1411, the telescopic rod 1442 extends into the sleeve 1441 accordingly. At this time, the compression spring 1443 is squeezed and shortened by the block 145. When the contact ball 146 is no longer in contact with the fireproof board 120 and a part of the glue outlet hole 1411 is extended out, the block 145 is driven by the compression spring 1443 to block the glue outlet hole 1411, thereby realizing the automatic blocking and opening of the glue outlet hole 1411. The structural design is ingenious and meets the use requirements.

[0034] As an optional embodiment, a plurality of through holes 1421 are provided on the inner cylinder 142, and a rotating shaft 150 movably connected to the side wall of the box body 110 is connected to one side of the inner cylinder 142, and a glue filling tube 160 movably penetrating the side wall of the box body 110 is connected to the other side of the inner cylinder 142, and the glue filling tube 160 is communicated with the inner cylinder 142, and the glue filling tube 160 is also movably connected to a shunt tube 170, and the shunt tube 170 is connected to a main flow tube 180, and the main flow tube 180 extends into the box body 110 and is connected to a pump 190, and the pump 190 is used to extract glue.

The rotating shaft 150 near the discharge end of the box 110 is connected to a driving motor 213. When the driving motor 213 is started, it can drive the transmission belt 212 to rotate, thereby driving all the driving wheels 211 and the corresponding rotating shaft 150 to rotate, thereby realizing the rotation drive of all the coating rollers 140.

[0038] It should be noted that the rotation of the rotating drum 130 can also be driven by a driving mechanism 210 of the same structure.

When the fireproof board 120 is clamped between the rotating roller 130 and the gluing roller 140, you can let go and stop pushing the fireproof board 120. When the fireproof board 120 completes coating on the upper and lower surfaces under the action of the rotating roller 130 and the gluing roller 140, it finally goes out from the discharge port 112 to facilitate subsequent material collection.

[0041] As an optional embodiment, two scrapers 230 are arranged up and down in the box body 110 near the discharge port 112. The two scrapers 230 are used to scrape the glue on the upper and lower surfaces of the fireproof board 120 respectively.

Since the thread directions of the first screw rod 243 and the second screw rod 244 are opposite, the upper and lower brackets 242 are driven to move closer to or away from each other, that is, the distance between the two scrapers 230 between the two brackets 242 is synchronously adjusted, and the operation is convenient and quick.

[0044] It should be noted that a limit pin can be provided on the hand crank 245, and the limit pin can be connected to a corresponding position on the top of the box body 110, so that after the adjustment is completed, the hand crank 245 is limited and fixed to prevent the hand crank 245 from being accidentally touched.
