[0022] Specifically, this type of composite board can be used as an outdoor floor. The particle board has a low hardness and a certain degree of rebound, which can provide a more comfortable feeling for people exercising on it. The multiple interconnected "L"-shaped storage grooves 161 thereon are narrow, which can prevent the groove feeling from being transmitted to the people exercising on it through the soft panel 17, and the formaldehyde purification adsorbent in the storage groove 161 can absorb formaldehyde in the particle board and glue to ensure human health. The fire-retardant varnish on the panel 17 can ensure that the wood grain is revealed while improving its fire resistance.

[0023] Furthermore, in the above embodiment, a storage bag can be provided in the storage tank 161, and the storage bag is used to store sodium bicarbonate. When the composite board has caught fire, the open flame will burn the storage bag, and the sodium bicarbonate in the storage bag will decompose at high temperature to produce carbon dioxide, and the carbon dioxide will displace the surrounding air to suppress the spread of the fire. Example

[0024] like Figure 1-8 As shown, a process for preparing a wood-like fiber reinforced composite board, which is used to prepare the wood-like fiber reinforced composite board of Example 1, includes a frame 1, on which are arranged: A movable plate 14, which is used to support a bottom plate 15; The movable block 11 has a movable bucket 116 for storing glue and support blocks 121 symmetrically distributed on both sides of the movable bucket 116, a clamping block 122 is movably provided on the support block 121, and a triggering block 123 staggered with the support block 121 is provided on the clamping block 122, and a glue coating roller 117 is movably provided inside the movable bucket 116; A guide groove 132, which is used to guide the movable block 11 to move; The following steps are also included: S1, place the bottom plate 15 on the movable plate 14, and place the middle plate 16 between the movable block 11 and the clamping block 122, with the trigger block 123 against the top of the middle plate 16; S2, the movable block 11 moves along the guide groove 132, and the glue roller 117 applies glue to the bottom of the middle plate 16 until the trigger block 123 is separated from the middle plate 16, and the clamping block 122 cooperates with the supporting block 121 to fix the middle plate 16 so that the middle plate 16 is opposite to the bottom plate 15, and then the middle plate 16 is placed on the bottom plate 15; S3, repeat the above operation, move the panel 17 to a position facing the middle plate 16, separate the movable bucket 116 from the support block 121, and bring the two support blocks 121 closer together, so that the middle of the panel 17 is concave and in contact with the middle plate 16; S4, the middle part of the panel 17 is bonded to the middle plate 16, the support block 121 and the clamping block 122 release the panel 17, and the panel 17 is attached to the middle plate 16 under the action of gravity; S5, taking out the bonded composite board and extruding it to shape it, and then coating the panel 17 with fireproof varnish.

[0025] Specifically, the movable block 11 is specifically divided into two pairs, a spring is arranged between the clamping block 122 and the movable block 11, a spring is arranged between the triggering block 123 and the clamping block 122, the thickness of the triggering block 123 is greater than the width of the storage trough 161, and a notch is opened on the movable plate 14 for workers to take the composite plate. The movable plate 14 is slidably installed on the frame 1, and the movable bucket 116 is connected to the pipe for conveying glue.

[0026] Furthermore, in the above embodiment, a roller can be provided at the bottom of the trigger block 123 to reduce the friction force when the trigger block 123 moves on the middle plate 16 and the panel 17 , and an electric telescopic rod can be provided between the movable plate 14 and the frame 1 .

[0027] In the above technical solution, when the production work is carried out, the bottom plate 15 is first placed on the movable plate 14, and then the clamping block 122 is manually pulled to increase the gap between the clamping block 122 and the support block 121, and the middle plate 16 is placed between the movable block 11 and the clamping block 122, and the clamping block 122 is released. The clamping block 122 moves downward under the action of the spring, and the trigger block 123 is pushed by the spring to abut against the top of the middle plate 16. At this time, the clamping block 122 is locked, and then the movable block 11 moves along the guide groove. 132 moves, and the glue roller 117 applies glue to the bottom of the middle plate 16 until the trigger block 123 between one pair of movable blocks 11 is separated from the middle plate 16, and the clamping block 122 cooperates with the support block 121 to fix the side of the middle plate 16, and the movable block 11 continues to move along the guide groove 132 until the trigger block 123 between the other pair of movable blocks 11 is also separated from the middle plate 16, and the clamping block 122 cooperates with the support block 121 to fix the other side of the middle plate 16. At this time, the middle plate 16 is between two trigger blocks. The middle plate 16 can be placed on the bottom plate 15, the support block 121 and the clamp block 122 are separated from the middle plate 16, and the above operation is repeated to move the panel 17 to the position facing the middle plate 16. At this time, the movable bucket 116 is separated from the support block 121, and the movable bucket 116 no longer supports the middle part of the panel 17. The two support blocks 121 move closer to the middle of the rack 1, so that the middle part of the panel 17 is concave and in contact with the middle plate 16. The panel 17 The middle part is bonded to the middle board 16 by the action of glue, and then the clamping block 122 and the supporting block 121 are separated from the corners of the panel 17. The corners of the panel 17 fall down under the action of gravity and fit on the top of the middle board 16. At this time, the movable board 14 can be driven to move. There is a certain gap between the movable board 14 and the frame 1, which is convenient for the staff to take out the composite board. After extrusion and shaping, the glue between the layers moves to the corners of the board, so that the glue is evenly distributed and the layers of board are firmly bonded.

[0028] As a further embodiment of the present invention, the guide groove 132 includes a first vertical portion 133 , a second vertical portion 134 , and parallel first inclined portions 135 and second inclined portions 136 . The movable block 11 is provided with a guide block 111 adapted to the guide groove 132 .

[0029] Specifically, the guide block 111 is square in shape, and a slope matching the first inclined portion 135 and the second inclined portion 136 is formed on the side wall of the guide block 111 .

[0030] Furthermore, in the process of the movable block 11 moving downward, the guide block 111 passes through the first vertical portion 133, the first inclined portion 135, the second vertical portion 134, and the second inclined portion 136 in sequence. In the first vertical portion 133, the clamping block 122 approaches the plate, and the triggering block 123 gradually abuts against the top of the plate. Then the guide block 111 moves along the first inclined portion 135, and the spacing between the two pairs of movable blocks 11 increases. The triggering block 123 moves along the top surface of the plate until the triggering block 123 between one pair of movable blocks 11 is staggered with the plate. The movable block 11 continues to move along the first inclined portion 135. When the guide blocks 11 move to the connection between the first inclined portion 135 and the second vertical portion 134, the two pairs of movable blocks 11 gradually trigger the blocks 123 to be staggered with the plate and fit with the side wall of the plate. At this time, the plate is facing the bottom plate 15 below. Then the guide block 111 moves downward along the second vertical portion 134, and the plate approaches the bottom plate 15. Then the guide block 111 moves along the second inclined portion 136, and the clamping block 122 separates from the plate. The plate continues to fall under the action of gravity and fits together with the plate below. Then the movable block 11 moves upward along the guide groove 132. The movable block 11 is staggered with the plate, and the plate will not hinder the movable block 11 from moving upward.

[0031] As another embodiment further provided by the present invention, a movable cylinder 115 for driving the glue coating roller 117 to rotate is disposed on the guide block 111 , and a rack 137 meshing with the movable cylinder 115 is disposed in the first inclined portion 135 .

[0032] Specifically, during the movement of the guide block 111 along the first inclined portion 135, the rack 137 on the first inclined portion 135 extends into the guide block 111 and engages with the movable cylinder 115, thereby pushing the movable cylinder 115 to rotate. The movable cylinder 115 drives the glue coating roller 117 to rotate, so that the glue coating roller 117 can apply the glue in the movable bucket 116 to the bottom surface of the plate, thereby facilitating the bonding of the plate with the plate below.

[0033] As another embodiment further provided by the present invention, a transmission rod 114 which rotates synchronously with the movable cylinder 115 is provided in the movable block 11, a synchronous belt is provided between the transmission rod 114 and the glue coating roller 117, and a retractable connecting strip 113 for limiting the synchronous belt is provided on the movable block 11.

[0034] Specifically, a synchronous chain is provided between the transmission rod 114 and the movable cylinder 115 .

[0035] Furthermore, during the rotation of the movable cylinder 115, the movable cylinder 115 drives the transmission rod 114 to rotate through the synchronous chain, and the transmission rod 114 drives the glue coating roller 117 to rotate through the synchronous belt, thereby applying the glue in the movable bucket 116 to the bottom of the plate. During the movement of the movable bucket 116 relative to the movable block 11, one end of the connecting strip 113 connected to the glue coating roller 117 can move with the movable bucket 116, while limiting the synchronous belt to prevent the synchronous belt from falling off (this is common sense, and it is only necessary to set C-shaped protrusions at the top and bottom of the connecting strip 113 to limit the synchronous belt from falling off, which will not be repeated).

[0036] As another embodiment further provided by the present invention, a slide bar 13 for driving the movable plate 14 to move is slidably provided in the frame 1, and a support bar 131 for supporting the middle part of the plate is provided on the slide bar 13.

[0037] Specifically, the guide block 111 is provided with a slider extending into the slide rod 13, the slide rod 13 is provided with a mortise and tenon adapted to the slider, the support rod 131 is slidably installed on the slide rod 13, a spring is provided between the support rod 131 and the slide rod 13, an electric telescopic rod is provided between the slide rod 13 and the frame 1, and the frame 1 is provided with a notch for the support rod 131 to move.

[0038] Furthermore, during operation, the electric telescopic rod extends to drive the slide bar 13 to move downward, and the tenon groove on the slide bar 13 pushes the slider to move, thereby driving the guide block 111 to move along the guide groove 132, and the support rod 131 supports the middle part of the plate to prevent the middle part of the plate from sagging due to gravity. When the plate moves to a predetermined position, the support rod 131 separates from the plate and retracts into the frame 1 to facilitate the bonding of the plate.

[0039] As another embodiment further provided by the present invention, a push rod 126 is provided on the support block 121 and extends through the movable block 11 to the inside of the frame 1 , and a guide slope 127 for resisting the push rod 126 is provided on the frame 1 .

[0040] Specifically, the push rod 126 passes through the movable block 11, the guide block 111, the slider and the slide rod 13 in sequence. The slide rod 13 is provided with a notch adapted to the push rod 126. The push rod 126 is specifically a self-elastic telescopic rod, and a spring is arranged between the support block 121 and the movable block 11.

[0041] Furthermore, in the process of the guide block 111 moving downward along the second vertical portion 134 of the guide groove 132, the push rod 126 gradually contacts the guide slope 127, and the guide slope 127 pushes the end of the push rod 126 to move closer to the plate. When the plate on the support block 121 is the harder middle plate 16 at this time, the support block 121 will not move relative to the movable block 11, and the push rod 126 is compressed. When the plate on the support block 121 is the softer panel 17 at this time, the push rod 126 will push the support block 121 to move closer to the middle part of the frame 1, so that the middle part of the panel 17 sags under the action of gravity, and then the middle part of the panel 17 is bonded to the middle plate 16 first.

[0042] As another embodiment further provided by the present invention, a traction rod 119 is slidably provided on the movable block 11 , and a first pulling cable 118 for pulling the movable bucket 116 to move is provided at the end of the traction rod 119 .

[0043] Specifically, a through hole adapted to the traction rod 119 is opened on the slider, a spring is arranged between the traction rod 119 and the slider, and one end of the traction rod 119 having the first cable 118 is the first end (such as Figure 5 As shown, the right end of the traction rod 119 is the first end).

[0044] Furthermore, during the downward movement of the guide block 111 along the first inclined portion 135 of the guide slot 132, the traction rod 119 gradually approaches and contacts the inner wall of the cavity of the frame 1, and the inner wall of the cavity of the frame 1 pushes the traction rod 119 to move (in a manner similar to that of FIG. 1 ). Figure 5 The end of the traction rod 119 drives the movable bucket 116 to move along the slide groove on the movable block 11 through the first cable 118, thereby separating the movable bucket 116 from the support block 121 so that the support block 121 can move relative to the movable block 11.

[0045] Furthermore, in the above embodiment, a slope may be provided at the bottom of the trigger block 123 so that the movable bucket 116 pushes the trigger block 123 during the movement, thereby preventing the trigger block 123 from hindering the movement of the movable bucket 116 .

[0046] As another embodiment further provided by the present invention, a locking block 124 for fixing the clamping block 122 on the supporting block 121 is provided, and the triggering block 123 moves to separate the locking block 124 from the supporting block 121 .

[0047] Specifically, a second pull cable 125 is arranged between the trigger block 123 and the locking block 124, a spring is arranged between the locking block 124 and the clamping block 122, a tenon for guiding the supporting block 121 is opened on the supporting block 121, a tenon 112 adapted to the tenon is arranged on the clamping block 122, the side wall of the locking block 124 is covered with a rubber layer, and a spring is arranged between the tenon 112 and the supporting block 121.

[0048] Furthermore, when the trigger block 123 is against the top of the plate, the second cable 125 between the trigger block 123 and the locking block 124 is in a relaxed state, and the locking block 124 is against the inner wall of the mortise and tenon of the support block 121 under the push of the spring, and the clamping block 122 is temporarily fixed on the support block 121. When the trigger block 123 is staggered with the plate, the trigger block 123 moves toward the outside of the clamping block 122 under the action of the spring, and the trigger block 123 drives the locking block 124 to move toward the inside of the clamping block 122 through the second cable 125. At this time, the clamping block 122 moves under the action of the spring to cooperate with the support block 121 to clamp the side of the plate.

[0049] As another embodiment further provided by the present invention, a plurality of mounting plates 138 are symmetrically arranged on the frame 1, and a plurality of rollers 139 for guiding the movement of the middle plate 16 are arranged on the mounting plates 138.

[0050] Specifically, the rollers 139 on the plurality of mounting plates 138 are staggered and covered with a rubber layer. A slope for pushing the support rods 131 to separate from the plate is disposed on the top of the mounting plate 138 in the middle.

[0051] Furthermore, in the process of the movable block 11 moving downward with the middle plate 16, the guide block 111 gradually enters the second vertical portion 134 of the guide groove 132. At this time, the side of the middle plate 16 contacts the roller 139, and the roller 139 limits the middle plate 16 to move only in the vertical direction. At this time, the guide block 111 moves along the second inclined portion 136 of the guide groove 132, so that the support block 121 and the clamping block on the movable block 11 are separated from the middle plate 16, and the middle plate 16 moves downward under the action of gravity and bonds with the bottom plate 15 below.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
