Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bamboo product processing tools, and in particular to a mildew-proof coating device for bamboo product processing. Background Technology
[0002] In the bamboo product processing industry, the coating quality of anti-mildew coating directly determines the product's service life, appearance quality, and market competitiveness. Due to the inherent characteristics of bamboo products, if the surface coating is uneven, problems such as localized anti-mildew failure and coating peeling may occur, which seriously affect product performance. Therefore, achieving uniform distribution of coating on the surface of bamboo products is the core link to ensure the coating process effect. Traditional bamboo product coating devices have significant shortcomings in paint distribution. These devices typically rely on drop nozzles to directly spray paint. Due to the lack of a dedicated diversion structure, the paint falls in a concentrated bundle, easily forming localized accumulations on the surface of bamboo products. Since bamboo products are often irregularly shaped, with curves, protrusions, or depressions, concentrated paint cannot cover complex areas, resulting in uneven coating in some areas and thin coating in others, creating a common problem of "uneven coating." Furthermore, the relative movement of the bamboo products with the stationary nozzle during transport further exacerbates the difference in paint adhesion, with paint accumulating near the nozzle and sparsely distributed further away, directly affecting the stability of the anti-mildew effect. Therefore, these problems need to be addressed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figure 1-4 This utility model discloses a bamboo product processing anti-mildew coating application device, including a processing box 5. The top of the processing box 5 is inverted and has a material drop nozzle. The processing box 5 has a processing chamber, and the bottom of the processing chamber is fixedly connected to a recycling box 1 for collecting coating. The recycling box 1 facilitates the collection of coating that drips or does not adhere to the surface of the bamboo product, avoiding direct waste of coating or contamination of the processing chamber, and providing a basis for the recycling and reuse of coating. The top of the recycling box 1 is equipped with two conveying components installed in sequence, and the top of the processing chamber is equipped with a diversion component. A hot air box 2 is installed at one end of the processing box 5. The hot air box 2 facilitates the drying speed of the anti-mildew coating on the surface of the bamboo product, so that the coating can be cured quickly, shortening the post-coating processing time, and avoiding problems such as coating peeling or mold growth caused by a humid environment. The hot air box 2 is connected to the processing chamber.
[0015] In this utility model, the side wall of the recycling box 1 has a liquid outlet, and a recycling pipe 3 is provided on the liquid outlet. A suction pump is installed at one end of the recycling pipe 3, and the other end of the recycling pipe 3 is threadedly connected to the spray head. The recycling pipe 3 facilitates the recycling of the paint, allowing the paint collected in the recycling box 1 to be transported back to the spray head for reuse in coating bamboo products, reducing paint consumption and lowering production material costs. The conveying components include a rotating motor installed on the outer wall of the processing box 5 and two plum blossom rollers 11 rotating on the inner wall of the processing chamber. A connecting cable 13 is sleeved between the two plum blossom rollers 11, and a flexible thin strip 12 is fixed to the connecting cable 13. The two conveying components are installed sequentially from high to low in the processing chamber. The output end of the rotating motor is coaxially fixed to one of the plum blossom rollers 11. The conveying components ensure stable transmission of the connecting cable 13, thereby driving the bamboo products to move smoothly and preventing the bamboo products from slipping during the conveying process. Two sliding rails 6 are fixed to the inner wall of the other end of the processing chamber. A guide arc plate 4 is slidably mounted on the sliding rails 6 to guide the bamboo products to move towards the bottom conveying component. The guide arc plate 4 facilitates the change of the direction of movement of the bamboo products and avoids jamming or falling during the conveying process. The diversion component includes two mounting blocks fixed to the inner walls of both sides of the processing chamber and a support shaft fixed to the bottom of the processing chamber. Each mounting block has a mounting groove, and a bidirectional hydraulic cylinder 10 is horizontally mounted in the mounting groove. Fixed blocks 9 are fixed to the two output ends of the bidirectional hydraulic cylinder 10. Push shafts 7 are fixed to the two fixed blocks 9. Diversion plates 8 are fixed to the two push shafts 7. The diversion component facilitates the dispersion of the concentrated paint falling, avoids local accumulation, and improves the coating uniformity. The diversion plate 8 is triangular in shape and has multiple leakage grooves and multiple bending points. The middle part of the diversion plate 8 is fixed to the support shaft.
[0016] Working Principle: When using this utility model, first connect each electrical component in this application to the power source. Then, after the device is started, the rotating motor on the outer wall of the processing box 5 drives the plum blossom rollers 11 to rotate. The connecting cable 13, which is sleeved between the two plum blossom rollers 11, moves in a circular motion. The flexible strip 12, which is fixed to the connecting cable 13, moves accordingly. The bamboo product is placed on the conveying component above. The flexible strip 12, due to its flexibility, adheres to the surface of the bamboo product and is smoothly conveyed forward under the drive of the connecting cable 13. The plum blossom rollers 11... The plum blossom-shaped structure increases friction with the connecting cable 13, effectively preventing slippage and ensuring stable transport of bamboo products. Then, when the bamboo products are transported below the diverter plate 8, the drop nozzles on the top of the processing box 5 spray anti-mildew coating downwards. At this time, the bidirectional hydraulic cylinder 10, through the extension and retraction of its output end, drives the push shaft 7 via the fixed block 9, causing the diverter plate 8, which is fixed to the push shaft 7, to adjust its angle around the support shaft. The triangular diverter plate 8 evenly distributes the concentrated falling coating, guiding it to more evenly cover the surface of the bamboo products passing below, avoiding... Localized accumulation and the bending points on the diversion plate 8 reduce collision damage between the bamboo products and the diversion plate 8, ensuring the integrity of the bamboo products. The drip trough allows excess coating not adhering to the bamboo products to pass through and drip into the recycling bin 1 below. Meanwhile, the bamboo products coated by the upper conveying component are guided by the guide arc plate 4 on the sliding rail 6 when they reach the other end of the processing chamber, and are smoothly transferred to the bottom conveying component. The guide arc plate 4 can be adjusted along the sliding rail 6 to accommodate bamboo products of different sizes. The bottom conveying component continues to move the bamboo products towards the hot air box. The device moves in two directions, and the hot air box 2 delivers hot air into the processing chamber to accelerate the drying and curing of the anti-mildew coating on the surface of bamboo products. This prevents the coating from peeling off or the bamboo products from becoming moldy due to a humid environment. Finally, the recovery box 1 collects the excess coating that falls from the drain trough of the diversion plate 8 and drips from the surface of the bamboo products. When the amount of coating in the recovery box 1 reaches a certain level, the suction pump starts and draws the coating out from the outlet of the recovery box 1 through the recovery pipe 3 and sends it back to the drop nozzle to achieve the recycling of the coating and reduce waste. This concludes the use of the anti-mildew coating coating device for bamboo product processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
