Description

Technical Field

[0001] The present application relates to the field of plywood, and in particular to a high-strength environmentally friendly plywood. Background Art

[0002] Plywood is a kind of man-made board. Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesives. Plywood is often used in the production of furniture, which is also the most common way we see plywood.

[0003] In the production process of plywood, the wood sections are directly peeled into the required thickness and then cut into the same size. The peeled wood boards are then coated with adhesive for fixing. They are then sent to a large hydraulic press for extrusion. The multiple layers of wood boards are squeezed into the required composite board.

[0004] In order to ensure that adjacent wooden boards are firmly fixed, a large amount of glue is applied on the boards. The glue will remain in the plywood after it is formed. During the use of the plywood, the chemical additives in the glue used for fixing may emit irritating odors and cause pollution within a certain range. Utility Model Content

[0032] The following is combined with Figure 1 —4 Provide further details of this application.

[0033] The embodiment of the present application discloses a high-strength environmentally friendly plywood.

[0034] Reference Figure 1 and Figure 2A high-strength environmentally friendly plywood comprises a fixing plate 2, both sides of which are provided with a wood board layer 1, the wood board layer 1 being a thin wood board, a fixing mechanism 5 being provided between the fixing plate 2 and the wood board layer 1, an insect-proof layer 3 being provided on the wood board layer 1, and a decorative layer 4 being provided on the insect-proof layer 3. When manufacturing the plywood, thin wood boards are placed on both sides of the fixing plate 2 and connected by the fixing mechanism 5, only a small amount of glue is applied between the thin wood boards and the fixing plate 2, and then the thin wood boards are sent to a pressing device to be pressed into a board, and then the insect-proof layer 3 is installed on the molding plate, and a decorative layer 4 is applied on the insect-proof layer 3 to complete the production of the plywood, and the fixing plate 2 and the fixing mechanism 5 play a major role in fixing the thin wood boards, thereby reducing the possibility of using a large amount of glue when producing plywood.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 5 includes a plurality of limit blocks 51 fixed on both sides of the fixing plate 2. The veneer is provided with a plurality of reinforcement holes corresponding to the limit blocks 51. The limit blocks 51 pass through the reinforcement holes, and a resistance component 52 is provided on the limit blocks 51. First, align the reinforcement holes on the veneer with the limit blocks 51 on the fixing plate 2, and then apply a small amount of glue between the veneer and the fixing plate 2 for temporary fixation. Then, let the limit blocks 51 pass through the reinforcement holes, and the veneer is close to the fixing plate 2. After the veneers on both sides of the fixing plate 2 are installed, they are sent into the pressing device, and the resistance component 52 on the limit blocks 51 is pressed. The resistance component 52 opens the limit blocks 51, and the limit blocks 51 use the reinforcement holes to fix the veneer on the fixing plate 2. By using the resistance component 52 to open the limit blocks 51, the veneer is fixed to the fixing plate 2 by the limit blocks 51, thereby reducing the amount of glue between the veneers.

[0036] Reference Figure 2 and Figure 3 The resistance component 52 includes a resistance cone 521, and a resistance groove 522 is provided on the limit block 51. The resistance groove 522 is cross-shaped, and the resistance cone 521 is located at the center of the resistance groove 522. When the resistance cone 521 on the limit block 51 is pressed, the resistance cone 521 enters the resistance groove 522 of the limit block 51 under pressure, and the resistance groove 522 divides the limit block 51 into four parts. When the resistance cone 521 is squeezed from the middle, the limit block 51 opens and fits tightly to the veneer under the pressure of the pressure device. The limit block 51 is opened by the resistance cone 521 to tightly contact the inner wall of the processing hole, so that the veneer can be fixed on the limit block 51.

[0037] Reference Figure 1 and Figure 4A plurality of tooth-shaped convex strips 6 are fixedly connected on both sides of the fixing plate 2, and the tooth-shaped convex strips 6 abut against the veneer board. When the fixing plate 2 and the veneer board are pressed together, the tooth-shaped convex strips 6 on the fixing plate 2 abut against the veneer board, and the tooth-shaped convex strips on the fixing plate 2 slowly embed into the veneer board under the action of pressure. By utilizing the tooth-shaped convex strips on the fixing plate 2 to restrict the veneer board, the stability between the veneer board and the fixing plate 2 can be further improved.

[0038] Reference Figure 1 and Figure 4 The insect-proof layer 3 is a camphor board, and a plug-in assembly is provided between the camphor board and the thin board. After the thin board and the fixing plate 2 are pressed together, the camphor board is fixed to the thin board by the plug-in assembly. The camphor board can emit camphor smell to keep ants away. By fixing one side of the camphor board on the thin board, the possibility of ants and insects gnawing on the thin board can be reduced.

[0039] Reference Figure 1 and Figure 4 The plug-in assembly includes a plurality of plug-in blocks 9 fixed on the camphor wood board, and a plurality of plug-in slots are provided on the thin wood board. After the thin wood board and the fixing plate 2 are pressed and fixed, a plurality of plug-in slots are provided on the thin wood board, and both ends of the plug-in slots are open. A plurality of plug-in blocks 9 are fixed on the camphor wood board, and then the plug-in blocks 9 are inserted into the plug-in slots to complete the fixing of the camphor wood board. By fixing the camphor wood board with the plug-in blocks 9 and the plug-in slots, the possibility of requiring a large amount of glue when fixing can be reduced.

[0040] Reference Figure 1 and Figure 4 The decorative layer 4 is a decorative fire retardant coating, which is evenly applied on the camphor wood board. After the camphor wood board is fixed, the decorative fire retardant coating is directly applied on the camphor wood board. The decorative fire retardant coating plays a decorative role. When a fire occurs, the decorative fire retardant coating will block the flame. By utilizing the fire retardant performance of the decorative fire retardant coating, the insect-proof layer 3 and the wood board layer 1 can be protected.

[0041] Reference Figure 1 and Figure 4 A plurality of reinforcing ribs 8 are arranged inside the fixing plate 2. The reinforcing ribs 8 are located inside the fixing plate 2. When the fixing plate 2 is produced, the reinforcing ribs 8 are evenly distributed on the fixing plate 2. Under the support of the reinforcing ribs 8, the strength of the fixing plate 2 is improved. By reinforcing the fixing plate 2 with the reinforcing ribs 8, the overall strength of the plywood can be improved.

[0042] Working principle: when manufacturing the plywood, first align the reinforcement holes on the veneer board with the limit blocks 51 on the fixed plate 2, then apply a small amount of glue between the veneer board and the fixed plate 2 for temporary fixation, and then let the limit blocks 51 pass through the reinforcement holes, the veneer board is close to the fixed plate 2, and after the veneer boards on both sides of the fixed plate 2 are installed, they are sent to the pressing device, the abutment components 52 on the limit blocks 51 are compressed, and the abutment components 52 open the limit blocks 51, and the limit blocks 51 use the reinforcement holes to fix the veneer board to the fixed plate 2. After the veneer board and the fixed plate 2 are pressed and fixed, a number of plug-in slots are opened on the veneer board, and the two ends of the plug-in slots are open. A number of plug-in blocks 9 are fixed on the camphor board, and then the plug-in blocks 9 are inserted into the plug-in slots to complete the fixation of the camphor board, and finally a layer of decorative fire retardant paint is applied on the camphor board.
