Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] With reference to Figure 1 - Figure 8 A device for applying a waterproof agent to a particle board, comprising a mixing box 1, a feeding pipe 2 fixedly connected to the upper end of the mixing box 1, wherein particle board fragments are added into the feeding pipe 2, and a discharge port is formed in the lower inner wall of the mixing box 1, and a sealing cover 45 matched with the discharge port is connected to the side wall of the mixing box 1 through a plurality of bolts.

[0038] An applying mechanism, comprising a U-shaped plate 3 fixedly connected to the upper end of the mixing box 1, a first rod 4 rotatably connected to the lower end of the U-shaped plate 3, a motor 12 fixedly connected to the upper end of the U-shaped plate 3, wherein the movable end of the motor 12 is fixedly connected to the upper end of the first rod 4, a dispersion disc 5 fixedly connected to the lower end of the first rod 4, wherein the cross section of the dispersion disc 5 is in the shape of a truncated cone (as shown in Figure 3 The bottom of the feeding pipe 2 is attached to the upper surface of the dispersion disc 5 (as shown in Figure 2As shown), so that the shaving board fragments can only flow out through the multiple dispersion grooves 6, the mixing box 1 is fixedly connected with a first annular pipe 7 and a second annular pipe 8 at the top, the first annular pipe 7 is provided with multiple first liquid outlets 9 at the bottom, the second annular pipe 8 is provided with multiple second liquid outlets 10 at the bottom, the aperture of the first liquid outlets 9 is smaller than the aperture of the second liquid outlets 10 (as shown Figure 3 As shown), the first annular pipe 7 and the second annular pipe 8 are fixedly connected with a liquid adding pipe 11 (as shown Figure 6

[0039] When the first rod 4 drives the dispersion disc 5 to rotate at high speed, at this time, the shaving board fragments in the dispersion groove 6 are subjected to a large centrifugal force, and then the shaving board fragments are thrown out by the multiple dispersion grooves 6, evenly dispersed in the mixing box 1, and the waterproof agent is sprayed out through the liquid adding pipe 11, the first annular pipe 7, the second annular pipe 8, the first liquid outlets 9 and the second liquid outlets 10, evenly sprayed on the evenly dispersed shaving board fragments, so that each shaving board fragment is contaminated with the waterproof agent before mixing and stirring, avoiding the prior art of directly adding the shaving board fragments and the waterproof agent to the mixer at one time, which can directly cause the waterproof agent to contact more with the shaving board fragments above and less with the shaving board fragments below, resulting in a long stirring time in the subsequent stirring process to mix them evenly.

[0040] The mixing box 1 is provided with a separation mechanism, which includes a fixed frame 13 fixedly connected to the inner bottom of the mixing box 1, a conveying cylinder 15 (as shown Figure 2 and Figure 4 The lower end of the dispersion disc 5 is fixedly connected with a second rod 16, the side wall of the second rod 16 is fixedly connected with a spiral conveying blade 17, the outer side wall of the spiral conveying blade 17 is attached to the inner side wall of the conveying cylinder 15, and the fixed frame 13 is located below the first annular pipe 7.

[0041] When the shaving board fragments are thrown out by the centrifugal force, the shaving board fragments with smaller weight are thrown out for a shorter distance, and at this time, the shaving board fragments with smaller weight are thrown out at a position within the fixed frame 13, and the shaving board fragments with larger weight are thrown out at a position outside the fixed frame 13, and when the motor 12 drives the spiral conveying blade 17 to rotate clockwise through the first rod 4, the dispersion disc 5 and the second rod 16, the spiral conveying blade 17 can continuously convey the shaving board fragments within the fixed frame 13 upward for mixing;

[0042] And because the aperture of the first liquid outlets 9 is smaller than the aperture of the second liquid outlets 10, and the fixed frame 13 is located below the first annular pipe 7, less waterproof agent can be conveyed to the fixed frame 13, so that the waterproof agent can penetrate the shaving board fragments with smaller weight, avoiding waste caused by excessive application of the waterproof agent.

[0046] The first sliding block 23, the inner wall of the U-shaped tube 22, the second sliding block 24, and the hydraulic oil are arranged so that when the first plate 19 moves downward, the second plate 21 moves upward. When the chipboard fragments in the fixed frame 13 need to be transported out subsequently, the first plate 19 can drive the first sliding block 23 to move downward at this time, and then under the action of the hydraulic oil, the second sliding block 24 and the second plate 21 drive the moving plate 18 to move upward, so that the upper surface of the moving plate 18 is flush with the upper surface of the fixed frame 13. At this time, the light-weighted chipboard fragments transported out of the conveying cylinder 15 will move out of the fixed frame 13 through the upper surface of the moving plate 18 and the upper surface of the fixed frame 13, and the heavy-weighted chipboard fragments and the light-weighted chipboard fragments will be mixed.

[0047] In this way, the heavy-weighted chipboard fragments and the light-weighted chipboard fragments can be mixed uniformly with the waterproof agent respectively and then mixed again. At this time, only the mixture needs to be uniformly mixed, and the problem of the waterproof agent does not need to be considered. The waterproof agent can be added according to different weights of the chipboard fragments, so as to avoid waste of the waterproof agent.

[0053] During the rotation of the dispersion disc 5, the rolling ball 44 on the fourth plate 47 will be in intermittent contact with the pressing wheel 43. When the fourth plate 47 is pressed by the pressing wheel 43 through the rolling ball 44, the fourth plate 47 will drive the plurality of dredging rods 40 to move outward through the fifth plate 41 and the vertical plate 38.

6. A method for applying a waterproofing agent to particleboard, comprising the particleboard waterproofing agent application device as described in claim 5, characterized in that, It also includes the following steps: S1. Add the particleboard fragments to the feeding pipe (2), and then drive the motor (12) to rotate clockwise. The dispersing disc (5) drives multiple dispersing tanks (6) to rotate. Under the action of centrifugal force, the particleboard fragments are evenly dispersed in the mixing box (1). S2. Waterproofing agent is delivered into the liquid filling pipe (11).
