[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] The following is in conjunction with the appendix Figure 1 Detailed explanation of a method for preparing an environmentally friendly wood-plastic composite material, the method comprising the following steps:

[0032] Step 1: Add resin and wood chips to the grinder separately to complete the preparation of resin powder and wood chip powder;

[0033] Step 2: Add resin powder, wood powder and processing aids into the mixing device to complete the mixing of multiple materials;

[0034] Step 3: Extrude and cool the mixed material.

[0035] Step 4: Cut and polish the cooled material to complete the preparation of environmentally friendly wood-plastic composite material.

[0036] The following is in conjunction with the appendix Figure 2-7As detailed in 9-11, the mixing device includes a mixing chamber 101, multiple hollow stirring rods 102, multiple sets of multiple stirring plates 103, multiple right-angle support plates 104, a bottom support plate 105, multiple vertical stirring plates 106, a hollow rotating cavity 107, and fixed support legs 108. Multiple hollow stirring rods 102 are evenly rotatably connected to the mixing chamber 101 through multiple round holes. Multiple sets of multiple stirring plates 103 are respectively fixedly connected to the multiple hollow stirring rods 102 by welding. Multiple right-angle support plates 104 are connected to the mixing chamber 101 through multiple round holes. The bottom support plate 105 is rotatably connected to the mixing chamber 101 via a straight cavity, and multiple right-angle support plates 104 are in contact with the bottom support plate 105. Multiple vertical stirring plates 106 are uniformly fixed to the bottom support plate 105 via welding. The hollow rotating cavity 107 is rotatably connected to the bottom support plate 105 via a round hole. Multiple hollow stirring rods 102 are rotatably connected to the hollow rotating cavity 107 via multiple round holes. The fixed support leg 108 is fixedly connected to the mixing chamber 101 via welding.

[0037] Furthermore, a heating plate is installed inside the mixing chamber 101. The heating plate can heat the resin powder, wood powder, and processing aids. The resin powder, wood powder, and processing aids are added to the mixing chamber 101 in a certain proportion, and the mixing process is completed within the mixing chamber 101. Multiple hollow stirring rods 102 can drive multiple sets of multiple hollow stirring plates 103 to rotate, thereby completing the stirring process of the resin powder, wood powder, and processing aids within the mixing chamber 101. The multiple hollow stirring rods 102 and the multiple sets of multiple hollow stirring plates 103 are all hollow structures and interconnected, allowing cold water to be added to the multiple hollow stirring rods 102 and into the multiple hollow stirring plates 103. Within the mixing chamber 101, multiple hollow stirring rods 102 and multiple sets of hollow stirring plates 103 are kept at a low temperature to further accelerate the mixing speed of resin powder, wood powder, and processing aids, achieving uniform mixing of resin powder, wood powder, and processing aids. Multiple right-angle support plates 104 limit the bottom support plate 105, preventing it from detaching from the mixing chamber 101. Each right-angle support plate 104 is rotatably connected with ball bearings, further reducing the friction between the right-angle support plates 104 and the bottom support plate 105. The bottom support plate 105 can also block the opening below the mixing chamber 101, and its rotation drives the multiple vertical stirring plates 106 to rotate. The movement of multiple vertical stirring plates 106 is opposite to the rotation direction of multiple sets of hollow stirring plates 103, generating a greater stirring force. The hollow rotating cavity 107 provides space for the multiple hollow stirring rods 102 to rotate. Cold water discharged from the multiple hollow stirring rods 102 will enter the hollow rotating cavity 107 and exit from the hollow rotating cavity 107. The fixed support legs 108 provide support and fixation, allowing the entire device to be placed stably on the ground. Resin powder, wood powder, and processing aids are added to the mixing chamber 101 in proportion. The rotation of the multiple hollow stirring rods 102 drives the multiple sets of hollow stirring plates 103 to rotate, achieving the mixing of various materials in the mixing chamber 101. The mixing process involves rotating the base plate 105, which in turn rotates multiple vertical stirring plates 106. The vertical stirring plates 106 rotate in the opposite direction to the multiple sets of hollow stirring plates 103, generating a greater stirring force to ensure uniform mixing of the various materials. During mixing, the heating plate inside the mixing chamber 101 is activated to simultaneously heat and stir the materials, further ensuring efficient mixing. Once the temperature of the materials reaches 60 degrees Celsius, cold water is added to the multiple hollow stirring rods 102, allowing the low-temperature multiple sets of hollow stirring plates 103 to stir the materials at 60 degrees Celsius, further improving the mixing efficiency.

[0038] The following is in conjunction with the appendix Figure 2-5As detailed in 9-11, the mixing device further includes a driving cavity 201, a plurality of sliding plungers 202, and a plurality of square sliding rods 203. The driving cavity 201 is fixedly connected to the hollow rotating cavity 107 by welding. The plurality of sliding plungers 202 are slidably connected to the hollow rotating cavity 107 through a plurality of round holes. The plurality of sliding plungers 202 are all fixedly connected to the driving cavity 201 by welding. The plurality of square sliding rods 203 are fixedly connected to the hollow rotating cavity 107 by welding. The plurality of sliding plungers 202 are slidably connected to the plurality of square sliding rods 203 through a plurality of square grooves.

[0039] Furthermore, the hollow rotating cavity 107 is provided with multiple discharge holes, and multiple sliding plugs 202 are slidably connected in the multiple discharge holes. Multiple telescopic rods are fixedly connected in the drive cavity 201, and the multiple telescopic rods are fixedly connected to the multiple sliding plugs 202. Multiple square sliding rods 203 can provide sliding space for the multiple sliding plugs 202 and limit them, so that the multiple sliding plugs 202 can only slide along the direction of the multiple square sliding rods 203. When the multiple materials in the mixing cavity 101 are mixed, the multiple telescopic rods can be activated to drive the multiple sliding plugs 202 to move outward, so that the multiple sliding plugs 202 are disengaged from the hollow rotating cavity 107. At this time, the processed material will be discharged through the multiple discharge holes on the hollow rotating cavity 107, and finally enter the hollow rotating cavity 107 and be discharged.

[0040] According to the instruction manual Figure 2-5 In detail, the mixing device further includes a geared motor I301 and a linkage gear I302.

[0041] Furthermore, after starting the geared motor I301, it can drive the linkage gear I302 to rotate. The rotating linkage gear I302 will drive the bottom support plate 105 to rotate, thereby driving multiple vertical stirring plates 106 to rotate. The rotation direction of the multiple vertical stirring plates 106 is opposite to the rotation direction of multiple sets of multiple stirring empty plates 103, thereby generating a greater stirring force.

[0042] According to the instruction manual Figure 2-6As detailed in section 8, the mixing device further includes multiple friction cone wheels 401, friction rotors 402, a reduction motor II 403, and a linkage gear II 404.

The friction rotors 402 and the linkage gear II 404 are meshed and connected for transmission.

[0043] Furthermore, after starting the geared motor III403, it can drive the linkage gear II404 to rotate. The rotating linkage gear II404 will drive the friction wheel 402 to rotate. The rotating friction wheel 402 can drive multiple friction cone wheels 401 to rotate through friction, thereby driving multiple hollow stirring rods 102 to rotate.

[0044] According to the instruction manual Figure 2-7 In detail, the mixing device further includes multiple retaining rings 501, hollow storage rings 502, and multiple drain pipes 503.

The multiple drain pipes 503 are uniformly and fixedly connected to the hollow storage rings 502 by welding. The multiple hollow stirring rods 102 are slidably connected to the multiple drain pipes 503 respectively.

[0045] Furthermore, multiple retaining rings 501 can provide a fixed space for the hollow storage ring 502, which stores cold water. The cold water in the hollow storage ring 502 will be discharged from multiple drain pipes 503. The cold water will enter multiple hollow stirring rods 102 through multiple drain pipes 503, thus completing the addition of cold water to multiple hollow stirring rods 102.

[0046] According to the instruction manual Figure 2-7 As detailed in section 9, the mixing device further includes an inlet pipe 601, a water pump 602, a water storage tank 603, and a reinforcing plate 604. The inlet pipe 601 is fixedly connected to the hollow storage ring 502 by welding. The water pump 602 is fixedly connected to the inlet pipe 601 by a snap ring. The water pump 602 is fixedly connected to the water storage tank 603 by welding. The reinforcing plate 604 is fixedly connected to the water storage tank 603 by welding. The fixed support leg 108 is fixedly connected to the reinforcing plate 604 by welding.

[0047] Furthermore, cold water enters the hollow storage ring 502 through the inlet pipe 601. The water pump 602 is equipped with a pump pipe and a transmission pipe. The pump pipe extends into the inlet pipe 601, while the transmission pipe is fixedly connected to the inlet pipe 601. Ice is added to the water storage tank 603 to continuously cool the water in the water storage tank 603, so that the water storage tank 603 contains cold water. The water pump 602 is started to transfer the cold water in the water storage tank 603 to the inlet pipe 601. At this time, the cold water will enter the hollow storage ring 502. The reinforcing plate 604 plays a reinforcing role, so that the water storage tank 603 is firmly fixed to the device.

[0048] According to the instruction manual Figure 2-4 As detailed in section 9, the mixing device further includes a return pipe 701, an extension pipe 702, and a sliding sleeve pipe 703. The return pipe 701 is fixedly connected to the water storage tank 603 by welding. The extension pipe 702 is slidably connected to the return pipe 701 by multiple keys and keyways. The sliding sleeve pipe 703 is slidably connected to the extension pipe 702 by a straight cavity. The hollow rotating cavity 107 is slidably connected to the sliding sleeve pipe 703 by a straight cavity.

[0049] Furthermore, after the cold water is discharged from the hollow rotating cavity 107, it can enter the extension pipe 702 and finally enter the return pipe 701, allowing the cold water to flow back into the water storage tank 603, thus completing the recycling of cold water. After the processing of various materials in the mixing cavity 101 is completed, the sliding sleeve 703 is moved downwards to disengage from the hollow rotating cavity 107, and the extension pipe 702 is slid towards the water storage tank 603. At this time, the materials processed in the mixing cavity 101 will be discharged from the hollow rotating cavity 107.
