In this embodiment, the mixture is made by mixing thermal insulation powder and base material fiber.

[0031] like Figure 1-Figure 2 As shown, a first combing mechanism 2 and a second combing mechanism 3 are installed on the frame platform 1, and the first combing mechanism 2 and the second combing mechanism 3 are vertically distributed. The first combing mechanism 2 reciprocates horizontally along the length direction of the material trough 12 to perform initial combing on the mixed material inside the material trough 12, and the second combing mechanism 3 reciprocates horizontally along the width direction of the material trough 12 to perform secondary combing on the mixed material inside the material trough 12 in different directions.

[0036] like Figure 4 As shown, the first combing head 27 includes an angle steel 271 fixedly mounted on the movable end of the electric telescopic rod 25, and a mounting groove 272 is provided on the other side of the angle steel 271. A plurality of combing teeth 273 are movably mounted inside the mounting groove 272.

[0038] During use, first start the electric telescopic rod 25 to move the first combing head 27 to the position of the material trough 12, and control the first combing head 27 to descend through the lifting gas rod 24 so that the bottom end of the combing teeth 273 is close to the inner bottom wall of the material trough 12, and start the electric telescopic rod 25 again to make the first combing head 27 reciprocate in the left and right directions in the material trough 12 to perform preliminary combing of the mixed material, and then restore the first combing head 27 to the initial position, and move the second combing head 31 to the inside of the material trough 12 to perform secondary combing of the mixed material in the front and back directions. After the secondary combing is completed, the second combing head 31 is reset, and finally the mold plate 13 is transported to the material trough 12 through the driving mechanism 14 to hot-press and solidify the mixed material after the secondary combing to make a nano thermal insulation board.

[0039] In the utility model, by arranging a first combing mechanism 2 on the right side of the frame platform 1 and a second combing mechanism 3 on the rear side of the frame platform 1, the first combing head 27 of the first combing mechanism 2 can perform preliminary combing on the mixture in the left-right direction, and then the second combing head 31 of the second combing mechanism 3 can perform secondary combing on the mixture in the front-back direction, which can improve the uniformity of the flattening of the mixture before pressing, and thus improve the uniformity of the thickness of the prepared nano thermal insulation board.
