[0002] Wood grain paper is a type of specialty paper. It is generally made from virgin wood pulp kraft paper as the base paper, which has high strength. Then, the surface is treated with processes such as embossing and dyeing to produce wood grain paper with various colors and patterns. Due to its high aesthetic appeal, practicality, and cost-effectiveness, wood grain paper is used in various fields, especially for packaging of various products.

[0003] In the processing of wood grain paper, drying is an important step in the forming process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a hot air circulating wood grain paper baking device, including a support 1 to provide stable support for the entire device. The support 1 is provided in two sets, and a drive component 4 is provided on the outside of the support 1. The two sets of support 1 are fixedly connected to a box 2 to form a baking space. An infrared heating tube 21 and a fan 22 are provided on the inner wall of the box 2 for baking the wood grain paper. The infrared heating tube 21 is fixedly connected to the inner wall of the box 2, and the fan 22 is fixedly connected to the inner wall of the box 2 and is located above the infrared heating tube 21. An adjustment component 3 is provided on the inner wall of the box 2 and the support 1. The adjustment component 3 includes a moving part 31 that is slidably connected to the inner wall of the support 1 and the box 2. When the threaded rod 33 rotates, the moving part 31 can move along the inner wall, driving the guide rod 32 to adjust its position to adapt to different specifications of wood grain paper.

[0032] Furthermore, a guide rod 32 is fixedly connected to the rear side of the moving part 31. The guide rod 32 and the guide rod 35 are arranged in a wave shape. When conveying the wood grain paper, the wood grain paper is between two adjacent sets of guide rods 32 and 35. The wave shape reduces obstruction to the wood grain paper during drying, thereby maintaining drying efficiency. Multiple sets of guide rods 32 are provided, with two adjacent sets of guide rods 32 arranged vertically. A threaded rod 33 is threadedly connected to the inner wall of the moving part 31 to drive the moving part 31 to move. The threaded rod 33 is rotatably connected to the inner wall of the box 2. A crank 34 is fixedly connected to the front side of the threaded rod 33 to facilitate the operator to rotate the threaded rod 33. Two sets of guide rods 35 are fixedly connected to the middle of the bracket 1 and the box 2 to support the middle of the wood grain paper.

[0033] Reference Figure 2 - Figure 4 The drive assembly 4 includes a drive roller 41 rotatably connected to the inner wall of the support 1. Driven by the drive motor 42, the roller rotates and is responsible for driving the wood grain paper to be smoothly conveyed in the device, ensuring that the wood grain paper moves at a predetermined speed and direction, and realizing continuous baking production. The drive motor 42 is installed on the front side of the support 1 to provide power for the rotation of the drive roller 41, ensuring that the drive roller 41 operates stably and continuously, thereby realizing stable conveying of wood grain paper and improving production efficiency. The output shaft of the drive motor 42 is fixedly connected to the front side of the drive roller 41 through a coupling.

[0034] Furthermore, the drive assembly 4 also includes a fixed frame 44, the upper part of which is hollow. The fixed frame 44 is slidably connected to the inner wall of the support 1. The inner wall of the fixed frame 44 is rotatably connected to the squeezing roller 43. During the conveying process, the pressure on the paper is automatically adjusted according to the thickness of the wood grain paper to ensure that the wood grain paper is tightly attached to the drive roller 41 and to prevent the wood grain paper from sliding or shifting. The fixed frame 44 is elastically connected to the support 1 through a compression spring 45, so that the squeezing roller 43 can adaptively adjust its position to stably squeeze the wood grain paper and ensure the conveying and drying effect. Two sets of adjustment components 3 are provided, and the two sets of adjustment components 3 are respectively located on the front and rear sides of the box 2.

[0035] Working principle: During use, the drive motor 42 is powered on and started, and its output shaft drives the drive roller 41 to rotate through the coupling. The friction generated by the rotation of the drive roller 41 drives the wood grain paper to move within the device, realizing continuous baking production. At the same time, the fixed frame 44 is elastically connected to the support 1 through the compression spring 45. The squeezing roller 43 inside the fixed frame 44 cooperates with the drive roller 41 under the action of the spring force, automatically adjusting the pressure on the paper according to the thickness of the wood grain paper, ensuring that the wood grain paper is tightly attached to the drive roller 41, preventing it from sliding or deviating during the conveying process, and ensuring the stability of the paper conveying.

[0036] While the wood grain paper is being conveyed, the infrared heating tube 21 starts working and releases heat. The fan 22 located above the infrared heating tube 21 starts and blows away the heat generated by the infrared heating tube 21, causing the hot air to circulate in the chamber 2. The hot air comes into full contact with the wood grain paper and transfers heat to the wood grain paper, causing the moisture in the wood grain paper to evaporate quickly and achieving the drying purpose.

[0037] According to the specifications of the wood grain paper, the operator turns the crank handle 34, which drives the threaded rod 33 to rotate. Since the threaded rod 33 is threadedly connected to the moving part 31, and the moving part 31 is slidably connected to the support 1 and the inner wall of the box 2, the rotation of the threaded rod 33 causes the moving part 31 to move on the inner wall of the support 1 and the box 2. The guide rod 32, which is fixedly connected to the rear of the moving part 31, moves synchronously with the moving part 31. The guide rod 32 cooperates with the wavy guide rod 35. The wavy design of the guide rod can restrict the edge of the wood grain paper, reducing the situation where the paper curls or wrinkles due to the hot air during the drying process. At the same time, this design will not greatly hinder the circulation of hot air and the drying effect, thus maintaining the drying efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
