DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0035] like Figures 1 to 6 As shown:

[0036] The invention discloses a device for pushing composite polymer materials from waste wood. The waste wood is made into standard wood strips with the same cross-section and different lengths, and is made into wooden squares with the same specifications through horizontal, longitudinal and vertical extrusion, coating with coupling agent, covering with polymer resin melt and reinforcing fiber, so that the waste wood is fully recycled and turned into treasure, thus reducing resource waste and achieving good economic benefits. The specific structure thereof includes a wood strip placement table 1. Since the waste wood strips are of different lengths, they can be processed into standard wood strips with the same cross-section and different lengths when they are processed, and the standard wood strips are placed on a wood strip placement table 1 for easy access in subsequent processes.

[0037] The rear end of the wood strip placement platform 1 is connected to a wood strip horizontal and vertical compression and conveying device 2. Specifically, the wood strip horizontal and vertical compression and conveying device 2 includes a clamping frame 9 for clamping the wood strips, compression rollers 10 arranged on both sides of the clamping frame 9 and used to compress the wood strips, a conveyor belt arranged below the clamping frame 9 and used to transport the moving wood strips, and a first driving device for driving the conveyor belt to move and the compression rollers 10 to roll; the wood strips on the wood strip placement platform are manually arranged neatly and clamped into the clamping frame 9, the size of the clamping frame matches the cross-sectional size of the wood strip body (the height of the wood strip is the same as the height of the clamping frame, and several wood strip bodies lined up are just the same as the width of the clamping frame), and the first driving device drives the conveyor belt to move and the compression rollers 10 to rotate, and while compressing several side-by-side wood strip bodies, they are conveyed and moved. Figure 6As shown: when the tail end of one of the wooden strips is completely entered into the card-joining frame, take the other wooden strips on the wooden strip placement table, align them with the tail end of the wooden strip, card them between the wooden strips, and continue to be transported and moved with the wooden strips. When the tail end of another parallel wooden strip is completely entered into the card-joining frame, repeat the previous steps to ensure that the entire card-joining and transporting process is carried out continuously.

[0038] The rear end of the wood strip horizontal and vertical pressing and conveying device 2 is connected to the wood strip vertical pressing and conveying device 3. Specifically, the wood strip vertical pressing and conveying device 3 includes a wood strip vertical pressing frame 11 connected with the clamping frame 9, a pressing roller 12 arranged on the upper and lower sides of the wood strip vertical pressing frame 11, and a second driving device for driving the rotation of the pressing roller 12. The wood strips squeezed out horizontally by the clamping frame 9 enter the wood strip vertical pressing frame 11, and the pressing roller 12 is driven to rotate by the second driving device, and the wood strips are rolled and squeezed vertically as they are conveyed and moved.

[0039] The rear end of the wood strip vertical pressing and conveying device 3 is connected to the coupling agent grouting mold 4. Specifically, the coupling agent grouting mold 4 includes a coupling agent grouting cavity 13 connected with the wood strip vertical pressing frame 11 and matching the size of the wood strip, and a coupling agent funnel 14 arranged above the coupling agent grouting cavity 13 and connected to the coupling agent grouting cavity 13. The wooden strips are squeezed in the horizontal, longitudinal and vertical directions to form a wooden square structure with a smooth surface. The wooden square structure continues to be conveyed and moved under the action of the conveying and rotating squeezing of the front conveying device, and enters the coupling agent grouting cavity. The coupling agent contained in the coupling agent funnel above the coupling agent grouting cavity drips into the coupling agent grouting cavity and coats the surface of the entering wooden square, thereby achieving the coating of the coupling agent on the surface of the wooden square. Since the size of the coupling agent grouting cavity matches the size of the wooden square, the wooden square can squeeze out excess coupling agent after passing through the coupling agent grouting cavity, thereby falling downward. In order to facilitate the collection of the fallen coupling agent and avoid waste and pollution, a collecting bucket 17 is set at its lower end. The collecting bucket 17 recycles the excess coupling agent and also avoids pollution to the ground environment.

[0040] The rear end of the coupling agent grouting mold 4 is connected to the coupling agent drying mold 5. The coupling agent drying mold 5 is a high-temperature heating device cavity with openings at both ends. The wood slowly passes through the coupling agent drying mold, and the coupling agent attached to the surface of the wood is dried by the high temperature environment, and the coupling agent can also penetrate deeper into the wood.

[0041] The rear end of the coupling agent drying mold 5 is connected to a reinforcing fiber felt pouring device 6. Specifically, the reinforcing fiber felt pouring device 6 includes a material trough 15 for containing polymer materials, a uniform distributor 16 for evenly distributing the reinforcing fibers, and a bonding and pressing box for pressing the reinforcing fibers bonded with the polymer resin melt onto the surface of the wood strip. The polymer resin melt contained in the material trough 15 tears the reinforcing fibers into uniform strips, and the strip-shaped reinforcing fibers sink into the polymer resin solution, so that the strip-shaped reinforcing fibers are covered with the polymer resin melt, and the strip-shaped reinforcing fibers covered with the polymer resin melt pass through the uniform distributor. After that, it is evenly attached to each surface of the wood, and when the wood slowly passes through the attaching and pressing box, it is tightly attached and pressed to the surface of the wood, so that the polymer resin and the surface of the wood are pushed and compounded. The uniform distributor is a square structure with a middle opening and uniform small holes around it. The strip-shaped reinforcing fibers pass through the uniform small holes, so that the spacing between each strip-shaped reinforcing fiber is the same, so that it can be evenly attached to the surface of the wood. At the same time, in order to further enhance the performance of the wood, a layer of reinforcing fiber cloth is wrapped on the surface of the wood attached with the strip-shaped reinforcing fibers, and the wrapping of the reinforcing fiber cloth and the strip-shaped reinforcing fibers are carried out simultaneously. Since the strip-shaped fiber cloth stained with polymer resin melt will squeeze out the excess polymer resin melt after entering the attaching and pressing box with the movement of the wood, in order to avoid its pollution of the environment and to achieve the recovery of the polymer resin, a collection bucket 17 is also set below it. After the wood strip-shaped reinforcing fibers and reinforcing fiber cloth are used to reinforce and wrap the wood, the wood continues to move under the drive of the aforementioned conveying device. In order to solidify the polymer resin melt, a polymer curing mold 7 is connected to its rear end. The polymer curing mold 7 is also a square cavity structure with openings at both ends. A heating device is provided inside the cavity. The wood wrapped with reinforcing fiber cloth, strip-shaped reinforcing fibers and polymer resin melt enters the polymer curing mold 7 for high-temperature accelerated curing to improve the mechanical properties of the wood.

[0042] After the wood blocks have passed through the polymer curing mold, in order to facilitate the storage and subsequent processing of the wood blocks, they are cut into wood blocks of uniform specifications for standby use by a cutting device. The cutting device can be set as a mobile cutting device with a speed equal to the moving speed of the wood blocks, or it can be a fixed cutting device. When cutting is required, the machine is stopped to stop the movement of the wood blocks, and then cutting is performed. In order to better control each electric device, the control switches of each device are uniformly set in the electric control cabinet 8 to facilitate the control of each device.

[0043] Since all structures of the present invention are long linear structures, the assembly line provided by the present invention can be arranged into multiple groups (such as Figure 1 As shown, 2 groups are set in the figure, and 3 groups or more can also be set).

[0044] A collecting bucket 17 for collecting the respective dripping melts is provided below the coupling agent grouting mold 4 and the reinforcing fiber felt pouring device 6 .

[0046] S1: Cut waste wood strips of different lengths into wood strips with the same cross-sectional dimensions and place them on a wood strip placement table;

[0047] S2: Arrange the wooden strips placed in step S1 neatly and send them into the clamping frame of the wooden strip horizontal and vertical pressing and conveying device. Through the transmission of the conveyor belt and the rolling of the pressing roller, several wooden strips are horizontally pressed and conveyed. When arranging the wooden strips, except for the end position, the wooden strips at other positions are arranged in a staggered manner (such as Figure 6 shown).

[0048] S3: The horizontally squeezed wood strip mark body enters the wood strip vertical pressing frame of the wood strip vertical pressing conveying device, and the wood strip mark body entering the wood strip vertical pressing frame is vertically squeezed by the rolling of the pressing roller;

[0049] S4: The vertically squeezed wood strip body enters into the coupling agent grouting cavity of the coupling agent grouting mold, and the coupling agent contained in the coupling agent funnel enters into the coupling agent grouting cavity and wraps the outer wall of the wood strip body. After the wood strip body passes through the coupling agent grouting cavity, the excess coupling agent on the surface drips into the collection bucket for recycling;

[0050] S5: drying the wooden strip label body with the coupling agent attached thereto through a coupling agent drying mold;

[0051] S6: making the reinforcing fibers into strips, and wrapping the strips of reinforcing fibers with a polymer resin melt, and passing through a uniform distributor, forming the strips of reinforcing fibers into a plurality of strips with equal spacing, and evenly attaching the strips to the outer wall of the wooden strip body with the coupling agent, and gradually attaching the strips to the outer wall as the wooden strip body moves, and pressing the strips through a pressing box;

[0052] S7: Wrap the wooden strip label in step S6 with a layer of reinforcing fiber cloth and perform high-temperature curing in a polymer curing mold; the wrapping with the reinforcing fiber cloth and the lamination of the strip reinforcing fibers wrapped with the polymer resin solution to the wooden strip label in step S6 are performed simultaneously.

[0053] S8: Cut the wood strips in step S7 into suitable lengths for later use, thereby completing the recycling of waste wood.

[0054] The above embodiment is only one of the preferred implementation modes of the present invention and should not be used to limit the protection scope of the present invention. Any changes or modifications that are made to the main design concept and spirit of the present invention and have no substantive significance, and the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention.
