[0002] Bamboo products refer to various materials and products made of bamboo, which are widely used in construction, furniture, decoration and other industrial purposes. However, since bamboo is rich in organic components, such as hemicellulose, lignin and cellulose, these components provide a good nutritional basis for mold. In a humid and warm environment, bamboo products are easily attacked by mold, resulting in problems such as mildew spots, discoloration and structural degradation on their surfaces. Therefore, in order to increase the service life of bamboo products, bamboo products need to be treated with mildew prevention. In the production process of bamboo products, the surface of the prepared bamboo products needs to be separately coated with a mildew inhibitor to improve the mildew resistance of the bamboo products. This mildew prevention process of bamboo products requires additional manual work, which is labor-intensive and inefficient, and cannot meet the requirements of automated production speed. Summary of the invention

[0022] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , 2 The figure shows a specific embodiment of the method for continuous heating and spraying mildew prevention of bamboo and the device used in the present invention. The method for continuous heating and spraying mildew prevention of bamboo in this embodiment comprises the following steps:

[0024] [1] Raw bamboo processing: processing raw bamboo into bamboo unit materials or bamboo products;

[0025] [2] Bamboo material transportation: bamboo unit materials or bamboo products are automatically transported through the conveying mechanism;

[0026] [3] Surface heating: The bamboo unit material or bamboo product is heated while being transported through the heating mechanism, thereby increasing the surface temperature of the bamboo unit material or bamboo product;

[0027] [4] Spraying for mildew prevention: The heated bamboo unit materials or bamboo products are sprayed with mildew inhibitors on their surfaces when they are transported through the spraying mechanism, so that the mildew inhibitors are fully absorbed by the surfaces of the bamboo unit materials or bamboo products.

[0028] The device used in the continuous heating and spraying mildew-proofing method for bamboo includes a frame 1, a conveying mechanism 2 is arranged on the frame 1, and a heating mechanism 3 and a spraying mechanism 4 are arranged in sequence along the conveying direction of the conveying mechanism 2, the heating mechanism 3 includes heat pipes 31 respectively arranged above and below the conveying mechanism 2, and the material is heated by the upper and lower heat pipes 31 when placed on the conveying mechanism 2 for conveying, and the spraying mechanism 4 includes a plurality of spray pipes 41 arranged at intervals at the top along the width direction, and the material is sprayed with a mildew inhibitor by the upper spray pipe 41 when it is conveyed through the spraying mechanism 4.

[0029] When the present invention is used, the original bamboo can be processed first, and then heated and sprayed after the original bamboo becomes the product unit or product shape to be processed later, so that the surface of the original bamboo is completely and fully covered with the mildew inhibitor to achieve the mildew-proof effect. The bamboo unit materials or bamboo products (hereinafter collectively referred to as bamboo products) are transported by the preceding mechanism or manually transported to the input end of the conveying mechanism 2 for automatic transportation. Heating and spraying do not require manual participation, which is more efficient and safer. The bamboo unit materials or bamboo products (hereinafter collectively referred to as bamboo products) are arranged in order on the conveying mechanism 2 for transportation. During the transportation process, the heating mechanism 3, specifically the heat pipe 31, which is orderly covered from above and below, emits heat to heat the surface of the bamboo products. The conveying mechanism 2 is set to a suitable length, so that the surface of the bamboo products reaches the required temperature when it reaches the spraying mechanism 4, and the mildew inhibitor is sprayed by a number of spray pipes 41 arranged at intervals above. The spraying method is conducive to the full dispersion of the mildew inhibitor in the space where the spray mechanism 4 is located, and then covers the entire surface of the bamboo products. The heated surface of the bamboo products can better absorb the mildew inhibitor, which is helpful to improve the mildew resistance of the bamboo products. Compared with the traditional manual brushing operation method, it is more efficient and has a better mildew resistance effect. In addition, the mildew inhibitor can be collected by adding a collecting mechanism at the bottom, and then recycled, so that the cost is further reduced.

[0030] Preferably, in step [1], in the raw bamboo processing, the bamboo unit materials include bamboo strips, bamboo bundles, and bamboo strips; and the bamboo products include bamboo veneer, bamboo laminate, reconstructed bamboo, and bamboo flooring. It is suitable for automated conveying, heating, and subsequent sufficient spraying, thereby replacing manual anti-mildew operations.

[0031] As an improved specific implementation, the conveying mechanism 2 includes a plurality of drive rollers 21 arranged at intervals. The material is supported on the drive rollers 21 and driven and conveyed by a power mechanism connected to the drive rollers 21. The gaps between the drive rollers 21 are used for the heat pipes 31 below to conduct heat upward.

[0032] like Figure 1 , 2 As shown, the plurality of driving rollers 21 can be selected in interval size according to the specifications of the bamboo products to be transported, which is highly flexible. There is no dead angle under the bamboo products during transportation, and the heat emitted by the heat pipes 31 below can also be more fully conducted to the space below the bamboo products through the intervals, so that the upper and lower heat pipes 31 cooperate to achieve more sufficient heating and temperature rise of the bamboo products as a whole, promoting the subsequent spraying and absorption of the anti-mold agent.

[0033] As an improved specific implementation manner, the conveying mechanism 2 further includes a plurality of transmission belts 22 , and the plurality of transmission belts 22 connect the plurality of transmission rollers 21 so as to make the transmission rollers 21 rotate synchronously.

[0034] like Figure 1 , 2As shown, a plurality of transmission belts 22 are connected to one end of a transmission roller 21 to drive the plurality of transmission rollers 21 synchronously. The transmission belts 22 are externally connected to an external power mechanism, such as a servo motor, which is beneficial to the uniform and stable transportation of bamboo products, thereby ensuring that the bamboo products are gradually heated and heated, and avoiding the occurrence of cracks in the bamboo products due to uneven heating.

[0035] As an improved specific implementation manner, the heat conducting pipe 31 is arranged in a continuous bent S-shape along the conveying direction of the conveying mechanism 2 .

[0036] like Figure 1 As shown, the continuously bent S-shaped heat pipe 31 can realize the recycling of heat energy by connecting the head and tail to an external heat source. After the heat medium passes through the heat pipe 31, the remaining residual heat can be recovered to reduce energy consumption. The heat pipe 31 crosses the wide direction of the conveying mechanism 2 through continuous bending S-shaped intervals, thereby covering the entire conveying length and performing uniform and stable heating.

[0037] Preferably, a medium for transferring heat energy is introduced into the heat pipe 31 , and the medium includes saturated steam, hot oil, hot air, and hot water, which can be selected according to actual needs and is relatively flexible.

[0038] As an improved specific implementation manner, annular teeth 32 for heat conduction are uniformly extended outward on the surface of the heat conduction pipe 31 in the width direction of the conveying mechanism 2 .

[0039] like Figure 1 As shown, the annular teeth 32 are arranged along the upper and lower heat pipes 31 across the width direction of the conveying mechanism 2. The outwardly extending contact surface formed by the annular teeth 32 greatly increases the surface area of ​​external contact, allowing heat to contact the external space more fully and promoting outward conduction of heat.

[0040] As an improved specific implementation manner, the S-shaped bends of the upper and lower heat-conducting pipes 31 are staggered, so that the upper and lower heat-conducting pipes 31 can complement each other in heat conduction at staggered projection positions.

[0041] like Figure 1 , 2 As shown, the bent S-shaped heat pipe 31 may have the lowest heat in the middle between the parallel heat pipes 31. By staggering the bent S-shaped portions of the upper and lower heat pipes 31, the positions with the lowest heat are staggered, so that when the upper and lower heat pipes 31 conduct heat, a certain complementary effect is played, and the heating of the bamboo products is more uniform and sufficient.

[0042] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
