[0002] In the current furniture industry, the most commonly used material is artificial board, and the main material of artificial board is wood particles, which have the characteristics of shrinkage and swelling. Among them, the phenomenon that the wet material shrinks its size due to drying is called shrinkage, and the phenomenon that the dry material increases its size and volume due to absorbing water is called swelling. Shrinkage and swelling mainly occur when the moisture content of wood is less than the fiber saturation point; the moisture content of particleboard types currently used in the industry is generally controlled at 5%-6%, and when the humidity is different in different places, the particleboard absorbs moisture and expands, resulting in size changes; at the same time, during the production process, the industry will use edge banding and glue to seal the edge of the particleboard and isolate the edge of the particleboard from the air, but during the production process, there are pinholes at the glue line position that are invisible to the naked eye. Water molecules in the air enter the particleboard through the pinholes, and then the moisture content inside the board increases, the wood particles expand, and then the size of the board changes.

[0025] Embodiment 1

[0026] like Figure 1-Figure 2 As shown, a waterproof treatment method for the edge of a panel edge band provided by the present invention comprises the following steps:

[0027] S1, coating: applying a waterproofing agent to the edge 11 of the edge band of the plate 1;

[0028] S2, heating: heating the waterproofing agent applied on the edge sealing portion 11;

[0029] S3, polishing: polishing the heated plate 1 to form a uniform hydrophobic film at the edge sealing 11.

[0030] In this embodiment, before coating, the plate 1 is first subjected to edge banding operation. The specific process is as follows: after the plate 1 comes from the edge banding machine, it is pre-milled and rubber roller, and the edge band is brought into trimming and tracking chamfering. After that, the plate 1 is conveyed to the coating station by the conveyor belt, and the edge band 11 is coated with a waterproofing agent at the coating station. Then, the plate 1 continues to move to the heating station, and the waterproofing agent coated on the edge band 11 is heated at the heating station, so that the waterproofing agent at the edge band 11 evaporates faster and is easier to form a hydrophobic film. After that, the plate 1 moves to the polishing station, and the plate 1 is polished at the polishing station. After polishing, the waterproofing agent is more evenly attached to the edge band 11 of the plate 1, making the hydrophobic film more uniform. After edge banding, the plate 1 is subjected to coating, heating, polishing and other processes in sequence, and a uniform hydrophobic film is formed at the edge band 11. The soaking test proves that there is no swelling after soaking in water for 24 days, which solves the problem of swelling of the plate.

[0031] The present invention forms a hydrophobic film at the edge seal 11 by coating a waterproofing agent at the edge seal 11, making it difficult for water molecules in the air to enter the interior of the board 1 through the pinholes. Therefore, a waterproofing agent with good volatility, low corrosiveness, and no traces can be coated on the edge seal 11 to achieve excellent waterproof performance; the edge seal 11 coated with the waterproofing agent is heated to make the waterproofing agent more easily penetrate into the pinhole position at a suitable temperature, and at the same time, the time for forming a hydrophobic film at the edge seal 11 is accelerated; after heating, the edge seal 11 is polished to make the waterproofing agent easier to solidify to form a hydrophobic film, and the hydrophobic film is more uniform, while not affecting the quality of the board surface. The present invention improves the defect of swelling of the board 1 after water enters the pinhole at the edge seal 11 of the industry board 1, and solves the problem of moisture absorption and expansion of the industry artificial board, thereby greatly improving the waterproofness of the artificial board, reducing the swelling, and allowing the board 1 to withstand more severe weather, such as the severe weather conditions of the south return.

[0032] As a preferred embodiment, in step S1, the waterproofing agent is applied to the edge sealing portion 11 of the edge sealing strip of the panel 1 by atomizing spraying.

[0033] In this embodiment, since the pinhole position of the edge sealing part 11 is extremely small, in order to make the waterproofing energy easily penetrate into the pinhole position, the present invention adopts an atomization spraying method to apply the waterproofing agent to the edge sealing part 11 of the edge sealing strip of the plate 1. In this way, the waterproofing agent is atomized to the edge sealing surface of the plate 1, which can make the spraying position uniform on the one hand and easily volatilize to form a thin film on the other hand. Specifically, the atomization spraying method can be a high-pressure atomization spraying method or an ultrasonic atomization spraying method.

[0034] As a preferred embodiment, in step S1 , a waterproofing agent is sprayed on the edge sealing portion 11 of the plate 1 using an atomizing nozzle 2 .

[0035] In this embodiment, the waterproofing agent is atomized into fine particles by the atomizing nozzle 2, so that the droplets are finer, the spray momentum is large, and the coverage is uniform. A smaller volume of waterproofing agent is obtained at the edge sealing 11, and the waterproofing agent can more easily penetrate into the pinhole position; specifically, the distance between the atomizing nozzle 2 and the edge sealing 11 is preferably 5-8mm, and a distance within this range can obtain a better atomization area.

[0036] As a preferred embodiment, in step S1, it also includes a sensing unit 5 electrically connected to the atomizing nozzle 2, and the sensing unit 5 is used to output a sensing signal when the panel 1 passes by. The atomizing nozzle 2 receives the sensing signal and starts spraying the waterproofing agent on the edge sealing 11 of the panel 1 after a delay of a preset time.

[0037] In this embodiment, in order to spray the waterproofing agent from the end of the plate 1, before the plate 1 passes through the atomizing nozzle 2, the sensing unit 5 first identifies the signal of the plate 1 passing through, and the atomizing nozzle 2 receives the sensing signal of the sensing unit 5. After the preset delay time is reached, the atomizing nozzle 2 starts to spray the waterproofing agent. In this way, the atomizing nozzle 2 has a spraying delay function, so that the effect of spraying from the end of the plate 1 can be achieved. Specifically, the sensing unit 5 is preferably a sensing head, and the height of the sensing head from the plate 1 is 5mm. According to the distance from the sensing head to the atomizing nozzle 2, the delay time is input on the waterproofing agent monitoring device 7. After the sensing head senses the plate 1, the atomizing nozzle 2 starts to spray the waterproofing agent after a delay of 2S.

[0038] As a preferred embodiment, atomizing nozzles 2 are provided above and below the plate 1 , and the two atomizing nozzles 2 are arranged opposite to each other, and the spraying direction of each atomizing nozzle 2 is perpendicular to the moving direction of the plate 1 .

[0039] In this embodiment, atomizing nozzles 2 are arranged at the upper and lower positions of the plate 1, so that the waterproofing agent can be sprayed on the edge sealing parts 11 on the upper and lower sides of the plate 1 at the same time, thereby improving the spraying efficiency; in addition, the spraying direction of the atomizing nozzle 2 is perpendicular to the moving direction of the plate 1, which is beneficial to improving the permeability of the waterproofing agent spraying, and at the same time, the waterproof film formed at the edge sealing part 11 is more uniform, and the atomization effect is better.

[0040] As a preferred embodiment, the atomizing nozzle 2 includes a nozzle body 21 and an atomizing needle 22 . The nozzle body 21 is provided with a flow regulating knob 23 , and the atomizing needle 22 is of a conical design.

[0041] In this embodiment, the waterproofing agent is sprayed out through the atomizing needle 22, and the atomizing needle 22 is of a conical design, so that the atomized particles become finer and more uniform, thereby achieving an ideal spraying effect; by setting a flow adjustment knob 23, the amount of waterproofing agent entering the nozzle body 21 can be adjusted, thereby controlling the atomization amount of the waterproofing agent, and achieving an effect in which the atomization amount can be controlled. Specifically, the flow adjustment knob 23 can be manually adjusted or intelligently controlled.

[0042] As a preferred embodiment, it also includes a waterproofing agent pressure tank 6 and a waterproofing agent monitoring device 7. The waterproofing agent pressure tank 6 is connected to the atomizing nozzle 2 and is used to provide waterproofing agent to the atomizing nozzle 2. The waterproofing agent monitoring device 7 is electrically connected to the atomizing nozzle 2 and the waterproofing agent pressure tank 6 and is used to monitor the operating status of the atomizing nozzle 2 and the liquid level status of the waterproofing agent pressure tank 6.

[0043] In this embodiment, the waterproofing agent is stored in the waterproofing agent pressure tank 6, and the atomizing nozzle 2 is connected to the waterproofing agent pressure tank 6 through a pipeline, so that the waterproofing agent in the waterproofing agent pressure tank 6 is sprayed on the edge sealing 11 through the atomizing nozzle 2; the operating state of the atomizing nozzle 2 and the liquid level state of the waterproofing agent pressure tank 6 are monitored by the waterproofing agent monitoring device 7, so that the spraying situation can be grasped in real time, making the spraying more intelligent and automated.

[0044] As a preferred embodiment, in step S2, a heating device 3 is used to heat the waterproofing agent coated on the edge sealing 11, and the heating device 3 is located above the plate 1. The heating part of the heating device 3 is parallel to the moving direction of the plate 1, and the height of the heating device 3 from the plate 1 is adjustable.

[0045] In this embodiment, the heating device 3 is located above the plate 1. When the plate 1 passes under the heating device 3, the heat generated by the heating device 3 heats the waterproofing agent at the edge sealing 11, so that the waterproofing agent is easy to volatilize to form a thin film, thereby accelerating the film forming time; specifically, the heating device 3 adopts a heat pipe method to heat the edge sealing 11, wherein the heat pipe temperature is 35-45°. Under this temperature range, the waterproofing agent sprayed on the edge sealing 11 of the plate 1 can evaporate faster and form a hydrophobic film more easily; the heating part of the heating device 3 is parallel to the moving direction of the plate 1, thereby expanding the heating distance of the edge sealing 11; the height position of the heating device 3 from the plate 1 is adjustable, so that it can adapt to plates 1 of different thicknesses, with higher flexibility. Preferably, the height of the heating device 3 of the present invention from the plate 1 is 5mm, and the heating effect is better at this height.

[0046] As a preferred embodiment, in step S3, an L-shaped polishing wheel 4 is used to polish both the surface and the side of the plate 1.

[0047] In the present invention, in order to polish the surface and sides of the plate 1, an L-shaped polishing wheel 4 is preferably used. The surface and sides of the plate 1 can be polished by the L-shaped polishing wheel 4. After polishing, the waterproofing agent is more evenly attached to the surface and sides of the edge sealing 11 of the plate 1, and the hydrophobic film is more uniform.

[0048] Embodiment 2

[0049] In step S1 , a waterproofing agent is applied to the edge band 11 of the panel 1 by brushing.

[0050] The difference between the second embodiment and the first embodiment is that the waterproofing agent is applied to the edge sealing part 11 of the edge sealing strip of the plate 1 by brushing, so that the waterproofing agent can be more focused on the edge sealing part 11 of the plate 1, and the amount of waterproofing agent used is less. However, the disadvantage of this method is that the coating amount of the waterproofing agent is difficult to control, but it can also achieve a waterproof effect.

A person skilled in the art may change, modify, substitute and modify the above embodiments within the scope of the invention without departing from the principles and purpose of the present invention. All such changes should fall within the scope of protection of the claims of the present invention.
