Description

Technical Field

[0001] The utility model relates to the technical field of veneer processing, in particular to a veneer drying device. Background Art

[0002] Veneer refers to a board made by attaching a thin layer of the same or different material to boards of varying thickness such as wood, bamboo, or polymer materials. Depending on the material and purpose, veneers can be divided into many types, such as wood grain veneers, metal veneers, stone grain veneers, and polymer veneers. The production process of veneers mainly includes the following key steps: material selection, cutting, bonding, sanding, drying, and decoration. Drying is to place the bonded veneers in a drying room for drying to remove excess moisture and solvents, and to heat the resin to a certain degree of curing, thereby improving the hardness and wear resistance of the veneer. When drying veneers, they are generally processed through a dedicated drying device, which includes a heating system, an air supply system, and a drying chamber. The veneer to be dried is placed in the drying chamber, and the heat generated by the heating system is blown onto the surface of the veneer through the air supply system to achieve the purpose of drying.

[0003] Regarding the above-mentioned related technologies, the inventors found that the position of the heat source of the existing drying device is fixed and cannot be adjusted according to the size of the veneer board. When drying small-sized veneer boards, the distance between the heat source and the veneer board is far, and the veneer board cannot be dried evenly, which reduces the quality of the product. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a veneer panel drying device, which can evenly blow hot air to dry veneers of different sizes, thereby expanding the scope of use and improving product quality.

[0005] To solve the above technical problems, the present invention adopts a technical solution: providing a veneer drying device, comprising: a drying box assembly and a support plate layer connected to an opening thereof, two guide rails embedded in the support plate layer at intervals, the two guide rails extending into the inner cavity of the drying box assembly, a drying placement frame assembly rollingly connected to the two guide rails, and a heat generating component provided in the inner cavity of the drying box assembly;

[0006] A front tilted blowing head assembly and a rear tilted blowing head assembly are respectively provided on both sides of the inner cavity of the drying box assembly. A telescopic driving rod assembly for driving the front tilted blowing head assembly to move horizontally is installed on one side of the drying box assembly, and the telescopic driving rod assembly for driving the rear tilted blowing head assembly to move horizontally is installed on the other side of the drying box assembly.

[0007] It also includes an exhaust component, the air inlet of the exhaust component is connected to the inner cavity of the drying box component through a pipeline, and the air outlet of the exhaust component is connected to the inner cavity of the front inclined blowing head component and the rear inclined blowing head component respectively.

[0008] By adopting the above technical solution, when in use, the veneers to be dried are placed at intervals on the drying placement frame assembly, and the heat generating component generates more heat, thereby increasing the temperature in the drying box assembly, and the exhaust assembly draws the heat in the drying box assembly into the inner cavity of the front inclined blower head assembly and the rear inclined blower head assembly. The hot air blown out by the front inclined blower head assembly enters the gap between adjacent veneers and mainly blows on the back of the veneer, and the hot air blown out by the rear inclined blower head assembly enters the gap between adjacent veneers and mainly blows on the front of the veneer, that is, the front and back of the veneer are evenly blown by the hot air, which enhances the uniformity of drying the veneer and improves the quality of the product. The corresponding telescopic drive rod assembly can drive the front inclined blower head assembly and the rear inclined blower head assembly to move in the horizontal direction, and veneers of different sizes can also be evenly blown with hot air at appropriate positions to dry them, which expands the scope of use and improves the quality of the product.

[0009] In a preferred example, the present invention can be further configured as follows: the drying placement frame assembly includes a frame body, the four corners of the lower plane of the frame body are respectively connected to support seats, the lower ends of the support seats are rotatably connected to rollers that are rollingly connected to the guide rails, the upper plane of the frame body is connected to two strip blocks at intervals, and also includes a U-shaped frame member connected to the strip blocks, and the U-shaped frame member includes U-shaped frame bodies respectively connected to the strip blocks.

[0010] By adopting the above technical solution, several veneer panels to be dried are placed in corresponding U-shaped frames. The U-shaped frames provide limited support for the veneer panels, and there are gaps between adjacent veneer panels. Since the rollers on the drying frame assembly are rollingly connected to the guide rails, it is convenient for workers to move the drying frame assembly into or out of the drying box assembly.

[0011] In a preferred example, the present invention can be further configured as follows: the front inclined blow-drying head assembly includes a rectangular sealed tube body and several vertical sealed tube bodies arranged at intervals; the vertical sealed tube body is arranged at an angle and is connected to the rectangular sealed tube body by at least two rigid ventilation tube bodies; the side of the vertical sealed tube body away from the rectangular sealed tube body is connected with several blowing nozzles at intervals.

[0012] By adopting the above technical solution, the exhaust component extracts heat into the rectangular sealed tube body 1, and the heat in the rectangular sealed tube body 1 is transmitted to the vertical sealed tube body 1 through the rigid ventilation tube body 1.

Since the heat flows at a fast speed, it can quickly absorb moisture in the veneer panels, thereby improving the drying efficiency.

[0015] In a preferred example, the present invention can be further configured as follows: the telescopic drive rod assembly includes an electric push rod and guide rods arranged on both sides thereof, and the electric push rod and the guide rods are both installed on the side of the drying box assembly.

[0016] By adopting the above technical solution, the telescopic rod of the electric push rod extends and retracts, which makes it easy to adjust the horizontal position of the front tilted blow head assembly or the rear tilted blow head assembly, and can evenly blow hot air to dry veneers of different sizes, thereby expanding the scope of use.

The heat in the front inclined blow head assembly and the rear inclined blow head assembly quickly acts on the surface of the veneer panel, thereby improving the drying efficiency.

[0019] In a preferred example, the present invention can be further configured as follows: the drying box assembly includes a drying box, and both sides of the opening of the drying box are hingedly connected to door panels.

[0020] By adopting the above technical solution, when the veneer panels on the frame assembly are moved into the drying box for drying, the door panel is closed to seal the opening of the drying box, thereby reducing heat loss and improving heat utilization.
