Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood processing technology, and in particular to a veneer water bath protection device. Background Technology
[0002] In the home decoration industry, in order to meet consumers' aesthetic needs in home decoration, natural wood veneers need to be bleached and dyed. The most common bleaching and dyeing method currently used is the high-temperature water bath method. During bleaching, water is used as a medium, and the addition of high temperature and alkali promotes the decomposition of hydrogen peroxide, thus bleaching the veneer. During dyeing, water is also used as a medium, and high temperature increases the gaps between wood molecules, accelerating the penetration of dye molecules into the wood, ultimately achieving the purpose of bleaching and dyeing the wood veneer.
[0003] However, during the long-term bleaching and dyeing process, alkalis, hydrogen peroxide, and high temperatures can damage the hardness of the wood, causing end-to-end tearing. In particular, some dyeing equipment has added circulation devices in the dyeing vat to make the bleaching and dyeing process more uniform, which accelerates the tearing of the wood veneer. Once the wood veneer is torn, it will hinder the subsequent processing and use. Severely torn veneers must be discarded directly, while minor ones must be repaired to remedy the situation, which increases processing costs. Summary of the Invention
[0004] To address the aforementioned problems, the present invention aims to provide a single-panel water bath protection device. Within a stainless steel frame, baffles are installed on the upper and lower perimeters of the inner side of the frame. The baffles are equipped with flow guiding holes. Without hindering water penetration to the end of the single-panel, the device reduces the impact of water flow on the end of the single-panel, minimizes tearing at the end of the single-panel, and prevents increased processing costs due to tearing of the end of the single-panel.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A single-panel water bath protection device includes a frame, which is rectangular in shape. The width of the frame forms a single-panel inlet on one side, and a storage space for placing single panels is formed inside the frame. The frame includes four vertical beams, and four horizontal beams are welded to the upper and lower sides of each vertical beam. Multiple limiting horizontal bars are welded between adjacent vertical beams and between opposite horizontal beams on the same upper and lower side. Multiple limiting vertical bars are welded between corresponding horizontal beams on the upper and lower sides. The device is characterized by:
[0007] The upper and lower sides of the storage space form a protection area for the end of the single panel. The bottom baffle, two long side baffles and two short side baffles enclose the protection area. The bottom baffle, long side baffles and short side baffles are welded to the inner wall of the frame. Several flow guide holes are opened on the bottom baffle, long side baffles and short side baffles.
[0008] In the above technical solution, the main body of the protective device is a frame (cage structure) welded from stainless steel pipes. A single-plate inlet is opened on one side of the frame for placing multiple single plates inside the frame. Bottom baffles, long side baffles, and short side baffles are set on the upper and lower sides inside the frame. They enclose and form a protective area to protect the ends of the single plates. Several flow-guiding holes are opened on these baffles to reduce the impact of water flow on the ends of the single plates without affecting the water penetration to the ends of the single plates, thereby minimizing tearing at the ends of the single plates and preventing increased processing costs due to tearing of the ends of the single plates.
[0009] When bleaching or dyeing wood veneer, first fill the dyeing vat with water and heat it to the required temperature, such as 50-70℃ for bleaching and 90-100℃ for dyeing. Then add the bleaching reagent or dye and let it dissolve for about half an hour. Next, put the veneer to be dyed into the water bath protection device and suspend the water bath protection device into the dyeing vat to keep the veneer warm for bleaching or dyeing. After the color reaches the target color, remove the water bath protection device from the dyeing vat to complete the bleaching or dyeing.
[0010] Preferably, the plurality of guide holes are arranged in a matrix on the bottom baffle, the long side baffle, and the short side baffle. In this technical solution, the matrix arrangement of the plurality of guide holes on the bottom baffle, the long side baffle, and the short side baffle allows water to penetrate evenly into all parts of the single plate. The relatively sparse arrangement of the guide holes provides better water flow impact resistance and also makes the structure of each baffle stable.
[0011] Preferably, the plurality of guide holes are arranged in a staggered matrix on the bottom baffle, the long side baffle, and the short side baffle. In this technical solution, the staggered matrix arrangement of the guide holes on the bottom baffle, the long side baffle, and the short side baffle allows water to penetrate evenly into all parts of the single plate. The relatively dense arrangement of the guide holes results in better dyeing or bleaching effects at the ends of the single plate and also makes the structure of each baffle stable.
[0012] Preferably, the diameter of the guide holes is 1cm to 2cm, and the spacing between adjacent guide holes is 0.5cm to 1cm. In this technical solution, the diameter of the guide holes is 1cm to 2cm, and the spacing between adjacent guide holes is 0.5cm to 1cm. This dimensional design of the guide holes and the spaces between them maximizes the flow of water between each veneer, thereby preventing damage to the veneer ends.
[0013] Preferably, the height of the long side baffle and the short side baffle is 20cm to 30cm. In this technical solution, the longitudinal height of the entire protected area is 20-30cm, that is, the height of the long side baffle and the short side baffle is 20cm to 30cm. In this way, the flow of water between each veneer can be guaranteed to the greatest extent, and the two most vulnerable ends of the veneer are protected.
[0014] Preferably, a frame plate is welded to the upper end of the crossbeam opposite the upper end of the frame, and a connecting shaft is provided between the frame plates. A connecting piece is welded to the upper end of the connecting shaft, and a hook is welded to the connecting piece. One end of the hook is welded to the side wall of the connecting piece, and the other end is welded to the upper end of the connecting piece. In this technical solution, the hook welded to the top of the frame facilitates the lifting of the entire frame into the dyeing vat.
[0015] Preferably, the connecting shaft includes a fixed shaft and a rotating cylinder. The two ends of the fixed shaft extend beyond the side support plates and are fixed with limit blocks. The rotating cylinder is rotatably sleeved on the outside of the fixed shaft and positioned between the side support plates. Retaining rings are formed on both sides of the rotating cylinder to abut against the inner walls of the support plates. The connecting piece is welded to the rotating cylinder. In this technical solution, the connecting shaft adopts a double-layer structure of a fixed shaft and a rotating cylinder, resulting in higher strength and greater structural stability. Furthermore, the rotating cylinder's rotatability allows the connecting piece and hook to flip between the side support plates, reducing space occupation and facilitating storage and use.
[0016] Preferably, a limiting diagonal brace is welded between the two vertical beams on one side of the frame, and the limiting diagonal brace is positioned longitudinally between the two limiting horizontal bars. In this technical solution, the setting of the limiting diagonal brace further enhances the structural strength of the frame and plays a protective and limiting role for the single panel.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0025] like Figures 1-3A single-panel water bath protection device is shown, comprising a frame, characterized in that: the frame is rectangular, with a single-panel inlet 1 formed on one side of the frame's width, and a storage space 2 for placing single panels formed inside the frame; the frame includes four vertical beams 3, and four horizontal beams 4 are welded to the upper and lower sides of the four vertical beams 3 respectively; multiple limiting horizontal bars 5 are welded between adjacent vertical beams 3 and between the upper and lower horizontal beams 4 on the same side; multiple limiting vertical bars 6 are welded between the upper and lower corresponding horizontal beams 4.
[0026] The upper and lower sides of the storage space 2 form a protection area for the end of the single board. The bottom baffle 7, two long side baffles 8 and two short side baffles 9 enclose the protection area. The bottom baffle 7, two long side baffles 8 and two short side baffles 9 are welded to the inner wall of the frame. Several guide holes 10 are opened on the bottom baffle 7, long side baffles 8 and short side baffles 9.
[0027] In the above technical solution, the main body of the protective device is a frame (cage structure) welded from stainless steel pipes. A single-plate inlet is opened on one side of the frame for placing multiple single plates inside the frame. Bottom baffles, long side baffles, and short side baffles are set on the upper and lower sides inside the frame. They enclose and form a protective area to protect the ends of the single plates. Several flow-guiding holes are opened on these baffles to reduce the impact of water flow on the ends of the single plates without affecting the water penetration to the ends of the single plates, thereby minimizing tearing at the ends of the single plates and preventing increased processing costs due to tearing of the ends of the single plates.
[0028] It should be noted that the limiting vertical bars are welded in sections to the crossbeams and the limiting horizontal bars, as well as between adjacent limiting horizontal bars, and also between the upper and lower crossbeams. This makes the limiting vertical bars and limiting horizontal bars more stable as they are on the same plane.
[0029] The bottom baffle, two long side baffles, and two short side baffles are welded to the inner wall of the frame. They can be welded to the horizontal beams and vertical beams, as well as to the limiting horizontal bars and limiting vertical bars.
[0030] Furthermore, the plurality of guide holes 10 are arranged in a matrix on the bottom baffle 7, the long side baffle 8, and the short side baffle 9. In this technical solution, the matrix arrangement of the plurality of guide holes on the bottom baffle, the long side baffle, and the short side baffle allows water to penetrate evenly into all parts of the single plate. The relatively sparse arrangement of the guide holes provides a relatively good water flow impact effect and also makes the structure of each baffle stable.
[0031] Furthermore, the plurality of guide holes 10 are arranged in a staggered matrix on the bottom baffle 7, the long side baffle 8, and the short side baffle 9. In this technical solution, the staggered matrix arrangement of the guide holes on the bottom baffle, the long side baffle, and the short side baffle allows water to penetrate evenly into all parts of the single plate. The relatively dense arrangement of the guide holes results in better dyeing or bleaching effects at the ends of the single plate and also makes the structure of each baffle stable.
[0032] Furthermore, the diameter of the guide hole 10 is 1cm to 2cm, and the spacing between adjacent guide holes 10 is 0.5cm to 1cm. This design of the guide holes and the spacing between them maximizes the flow of water between each veneer, thereby preventing damage to the veneer ends.
[0033] Furthermore, the height of the long side baffle 8 and the short side baffle 9 is 20cm to 30cm. In this technical solution, the longitudinal height of the entire protected area is 20-30cm, that is, the height of the long side baffle and the short side baffle is 20cm to 30cm. In this way, the flow of water between each veneer can be guaranteed to the greatest extent, and the two most vulnerable ends of the veneer are protected.
[0034] Furthermore, a frame plate 11 is welded to the upper end of the crossbeam 4 opposite to the upper end of the frame. A connecting shaft is provided between the frame plates 11, and a connecting piece 12 is welded to the upper end of the connecting shaft. A hook 13 is welded to the connecting piece 12. One end of the hook 13 is welded to the side wall of the connecting piece 12, and the other end is welded to the upper end of the connecting piece 12. In this technical solution, the hook welded to the top of the frame facilitates the entire frame being hoisted into the dyeing vat.
[0035] Furthermore, the connecting shaft includes a fixed shaft 14 and a rotating cylinder 15. The two ends of the fixed shaft 14 extend out from the side support plates 11 and are fixed with limiting blocks 16. The rotating cylinder 15 is rotatably sleeved on the outside of the fixed shaft 14 and positioned between the side support plates 11. Retaining rings 17 are formed on both sides of the rotating cylinder 15 that abut against the inner walls of the support plates 11. The connecting piece 12 is welded to the rotating cylinder 15. In this technical solution, the connecting shaft adopts a double-layer structure of a fixed shaft and a rotating cylinder, resulting in higher strength and a more stable structure. Furthermore, the rotating cylinder allows the connecting piece and hook to flip between the side support plates, reducing space occupation and facilitating storage and use.
[0036] Furthermore, a limiting diagonal brace 18 is welded between the two vertical beams 3 on one side of the frame, and the limiting diagonal brace 18 is positioned longitudinally between the two limiting horizontal bars 5. In this technical solution, the setting of the limiting diagonal brace further strengthens the structural strength of the frame and plays a protective and limiting role for the single panel.
[0037] When bleaching or dyeing wood veneer, first fill the dyeing vat with water and heat it to the required temperature, such as 50-70℃ for bleaching and 90-100℃ for dyeing. Then add the bleaching reagent or dye and let it dissolve for about half an hour. Next, put the veneer to be dyed into the water bath protection device and suspend the water bath protection device into the dyeing vat to keep the veneer warm for bleaching or dyeing. After the color reaches the target color, remove the water bath protection device from the dyeing vat to complete the bleaching or dyeing.
