[0035] Then, the completely laminated plant fiber decorative panel is moved one by one to the interlayer of the hot pressing panel mechanism until all the interlayers of the hot pressing panel mechanism are placed with the plant fiber decorative panel, and the plant fiber decorative panel is heated and pressed at the same time, and the temperature is gradually increased, and finally the hot pressing temperature of the plant fiber decorative panel is stabilized at 120℃, the total hot pressing time is controlled at 40min, the surface of the hot pressing panel mechanism is cooled after hot pressing, and the plant fiber decorative panel in the hot pressing panel mechanism is taken out after the temperature is controlled to 30℃, and then the edge trimming and polishing of the plant fiber decorative panel are performed;

[0036] The low-density plant fiber density board with high water absorption is selected, and a fireproof, moisture-proof, oil-proof, anti-static, weather-resistant and corrosion-resistant fireproof plate which is not easy to deform is obtained through the processes of immersion in phenolic resin glue, heating, roller pressing and cooling. Compared with the fireproof plate which is made by using surface color paper and multiple layers of high-grade kraft paper through resin glue immersion and high-temperature pressing, the plant fiber decorative plate has stronger toughness, better impact resistance and better durability.

[0037] In view of the panel decoration paper fitting work in the preparation process of the plant fiber decorative plate, the plant fiber plate is uniformly moved to the transmission roller group 3 in the transmission frame 2 through the movable clamping arm after being immersed in glue, as shown in Figure 2 The cross slide one 9 and the cross slide two 10 are fixed on the base 1, the cross slide one 9 and the cross slide two 10 are alternately placed, and the sliding grooves 11 are formed on the cross slide one 9 and the cross slide two 10, as shown in Figure 4 The sliding blocks 12 are slidably connected in the sliding grooves 11 on both sides, the lock rods 15 are movably connected on both sides of the sliding blocks 12 on the cross slide one 9 and the cross slide two 10, and the transmission teeth two 21 are movably connected on one side of the lock rods 15;

[0038] The motor 17 is installed on the top of the base 1, the output shaft 18 is fixed on the output end of the motor 17, and the two belt pulleys one 19 are movably connected on the output shaft 18, the belt pulleys two 20 are movably connected on the outside of the cross slide one 9 and the cross slide two 10, the belt pulleys two 20 and the belt pulleys one 19 are connected through the belt, and the transmission teeth two 21 connected with the belt pulleys two 20 on the cross slide one 9 and the cross slide two 10 are synchronously rotated through the rotation of the motor 17;

[0040] The cross slide one 9 and the cross slide two 10 are alternately placed, so that the connection points of the sliding blocks 12, the plate placing table 13 and the clamping table 14 on the cross slide one 9 and the cross slide two 10 are separated, so as to ensure that the sliding blocks 12 move on the cross slide one 9 and the cross slide two 10, and the plate placing table 13 and the clamping table 14 are always horizontally placed, which is beneficial to the subsequent placement and movement of the plant fiber plate;

[0041] Involving the specific lamination work of plant fiberboard and panel decorative paper, such as Figure 3 As shown, the transmission gear 21 on the side of the cross slide 19 rotates to realize the clockwise rotation of the transmission gear 16 on the lock rod 15. At the same time, the clamping platform 14 connected to the slider 12 at the front end of the lock rod 15 moves to the rightmost side, and the board placement platform 13 is flush with the clamping platform 14 and has a tendency to move downward. At this time, the clamping platform 14 is picking up the panel decorative paper.

[0042] like Figure 2 As shown, since melamine glue is applied to both sides of the panel decorative paper, a rubber roller 6 is first installed on the fixing frame 4 at the top of the transmission frame 2, and the surface of the rubber roller 6 is covered with melamine glue using the glue box 1 5 and the glue box 2 7. The glue box 2 7 at the top continuously pours melamine glue onto the surface of the rubber roller 6, and the melamine glue is continuously applied to the top of the panel decorative paper through the rotation of the rubber roller 6. The glue box 1 5 at the bottom of the panel decorative paper immerses the bottom rubber roller 6, and the bottom surface of the panel decorative paper can also be coated with the glue as the rubber roller 6 rotates.

[0043] A locking frame 8 is also installed on the top of the transmission frame 2. The locking frame 8 completes the locking and releasing work of the panel decorative paper through rollers, making it convenient for the subsequent clamping platform 14 to clamp the panel decorative paper;

[0045] Then, when the clamping table 14 drags the panel decorative paper to the leftmost position of the cross slide 1 9 and the cross slide 2 10, the board placing table 13 carrying the plant fiber board upward is flush with the clamping table 14. At this time, the plant fiber board is in contact with the bottom of the panel decorative paper. When the motor 17 stops rotating the pulley 19, the plant fiber board and the panel decorative paper are in contact and fixed. The excess panel decorative paper needs to be cut.

After the cutting of the panel decorative paper on the plate placing table 13 is completed, the carrying mechanism 28 comes to the top of the plate placing table 13 in advance, and then the plate placing table 13 is lifted to move the plant fiber decorative plate to the bottom of the carrying mechanism 28. When the carrying mechanism 28 completes the clamping and fixing of the plant fiber decorative plate, the plate placing table 13 moves downward at the same time as the material clamping table 14 moves rightward. Then, the two are flush at the middle intersection. At this time, the clamp 23 on one side of the material clamping table 14 contacts the panel device paper on the locking frame 8, reacquires the panel decorative paper coated with glue, and the carrying mechanism 28 moves the plant fiber decorative plate semi-finished product to the hot pressing equipment one by one. After 120 DEG C and 40 min of continuous hot pressing, the plant fiber decorative plate is formed.

[0049] With the longitudinal movement of the plate placing table 13 and the transverse movement of the material clamping table 14, the panel decorative paper and the plant fiber plate are continuously contacted and laminated, and the raw material conveying on the transmission frame 2 and the transfer of the formed plant fiber decorative plate by the carrying mechanism 28 are matched, so that the complete high-speed automatic lamination work of the plant fiber plate and the panel decorative paper is realized.
