Description

Technical Field

[0001] The invention relates to the technical field of wood-plastic door panels, and in particular to a flame-retardant wood-plastic door panel and a processing method thereof. Background Art

[0002] WPC door panels are made of a composite material made of wood fiber and thermoplastics through a special process. This material combines the beauty of wood and the durability of plastic. It not only has good heat and sound insulation effects, but is also easy to clean and maintain, and is light in weight and easy to install. WPC door panels have rich colors and textures that can imitate natural wood and meet the needs of different decoration styles. Flame retardancy is crucial for WPC door panels, especially when used in homes and public buildings. Although WPC materials themselves have certain flame retardant properties, their flame retardancy is not enough to fully meet the requirements of modern building fire safety regulations. Therefore, when producing WPC door panels, flame retardants are usually added to improve their fire resistance. These flame retardants can act quickly when encountering a fire source, forming a protective film that isolates oxygen and heat, slows down the spread of flames, and thus buys valuable time for personnel evacuation.

[0003] In order to enhance the fireproof effect, the current wood-plastic door panels will be installed or attached with a layer of more heat-resistant fireproof board, so that the door panels form a sandwich structure. Although the flame retardant effect is improved, this type of door panel still has the following problems:

[0004] 1. When the surface of the wood is heated in one area, the heat is still relatively concentrated, which makes it easy to reach high temperatures and burn, and the flame retardant effect is poor;

[0005] 2. When the fireproof board is attached to the surface of the door panel, there is a lack of resistance between the two bonding planes, which makes the fireproof board easy to shift during the attachment process, and the fireproof board is easy to peel off after attachment, reducing the stability of the structure.

[0006] In summary, there is a need for a wood-plastic door panel that is thermally conductive, flame retardant and structurally stable. Summary of the invention

[0058] S2, fixed plate interior;

[0059] The door panel body 1 is sent to the inside of the assembly equipment, and the internal assembly parts of the flame-retardant wood-plastic door panel according to claim 1 are positioned and assembled;

[0060] The assembly equipment includes a feeding mechanism 5, a plate fixing mechanism 6, a pushing mechanism 7 and an inserting mechanism 8. The door panel body 1 passes through the feeding mechanism 5 and enters the interior of the plate fixing mechanism 6 for positioning. The inserting mechanism 8 inserts the graphene core 2 and the steel lining 3 into the interior of the door panel body 1.

[0061] The above steps are specifically as follows: the door panel body 1 is placed on the first loading platform 51 and fits with the elastic sleeve 521, the electric roller 52 is started to push the door panel body 1 through the bottom of the pasting plate assembly 53 with the fireproof board 4 wound thereon, and the door panel body 1 is inserted between the two groups of rolling and pushing assemblies 74 of the pushing mechanism 7, and the first motor 62 is started to drive the first screw 63 to rotate, so that the pushing mechanism 7 as a whole drives the door panel body 1 to move in the direction of the inserting mechanism 8, and the fixed frame 71 drives the top plate 75 to move and separate from the top column 535, and the first spring 534 pulls the bearing column 532 downward to make the reel 531 drop, and at the same time, the second motor 741 is started to drive the rotating shaft 744 to rotate, so that the pushing roller 743 rotates and pushes the door panel body 1 to move quickly to the second loading platform 81, and at the same time, the pushing roller 743 rolls and fits with the top block 643, and the side stop wheel 764 rolls and fits with the side of the door panel body 1 to ensure the stability of the transportation of the door panel body 1;

[0062] The first pneumatic rod 645 is started to push the top block 643, and the top block 643 pushes the push roller 743 to slide on the rotating shaft 744 and stretch the second spring 745, and the chamfered structure at one end of the push roller 743 fits with the inner inclined surface of the attachment groove 14 of the door panel body 1, thereby accurately positioning the door panel body 1;

[0063] Then, multiple graphene cores 2 are placed on the pad 85, and the steel lining 3 is placed in the side groove 851 and separated by the partition plate 654. The third motor 83 is started to drive the second screw 86 to rotate, and the second push plate 84 pushes the graphene core 2 and the steel lining 3, and inserts them into the second inner slot 13 and the first inner slot 12 of the door panel body 1 respectively. When the second push plate 84 moves to the position of the partition plate 654, the graphene core 2 and the steel lining 3 can be stably inserted into the door panel body 1.

[0064] S3. Send board for exterior decoration;

[0065] The pushing mechanism 7 pushes the door panel body 1 out from the inside of the feeding mechanism 5, and at the same time, the feeding mechanism 5 attaches the fireproof board 4 to the door panel body 1, and then the door panel body 1 is turned over, and the pushing mechanism 7 pushes the fireproof board 4 back and forth, and the feeding mechanism attaches the fireproof board 4 to the other side of the door panel body 1, completing the door panel assembly;

[0066] The above steps are specifically as follows: start the first motor 62 and the second motor 741 to reversely transport the installed door panel body 1. When the door panel body 1 is guided to move to the bottom surface of the reel 531, start the glue injection box 542 to inject glue into the glue brushing plate 544.

After it is completely attached, insert the top plate 75 to lift the top column 535, cut off the fireproof board 4 to ensure that the attachment edge is flush, and then turn the door panel body 1 over for transportation, and attach the fireproof board 4 to the other side of the door panel body 1.

[0067] By sending the door panel body 1 to the inside of the assembly equipment for positioning, and assembling the internal assembly parts and the external assembly parts on the door panel body 1 in turn, a complete flame-retardant wood-plastic door panel is obtained, and the assembly can be completed only by reciprocating the door panel body 1, thereby improving the assembly efficiency and assembly accuracy of the door panel.
