Description

Technical Field

[0001] The utility model relates to the field of plywood manufacturing, and specifically relates to a plywood drying device. Background Technique

[0002] Plywood is a board made by gluing multiple layers of wood, usually composed of three or more wood chips that are cross-laminated and glued together with glue. Plywood has excellent strength and stability and is widely used in furniture manufacturing, construction, decoration and other fields.

[0003] The moisture in wood is an important condition for the growth of mold and pests. Therefore, plywood needs to go through a drying process before multi-layer gluing. The drying process can reduce the moisture content of the wood, thereby reducing the occurrence probability of mold and pests. At the same time, natural wood contains a high amount of moisture. When making plywood, if the moisture content of the wood is too high, it will cause the glue to not fully penetrate and cure, thus affecting the gluing strength. Therefore, before plywood is put into processing and gluing, it needs to be dried to remove the moisture in the board body. Drying is mostly carried out by natural air drying and hot air drying. Natural air drying is the most commonly used method at present, but it has low efficiency and a long production cycle. Hot air drying can shorten the drying cycle, but hot air drying often requires one side of the plywood to be used as a support, resulting in the moisture not being able to be discharged from the support surface, resulting in poor drying effect, and it is necessary to flip the board surface for secondary drying, with poor drying effect and a cumbersome process. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is that hot air drying can shorten the drying cycle. When plywood uses hot air drying as a drying means, it often requires one side of the plywood to be used as a support, resulting in the moisture not being able to be discharged from the support surface, resulting in poor drying effect, and it is necessary to flip the board surface for secondary drying, with poor drying effect and a cumbersome process.

[0006] (II) Technical Solution

[0007] To solve the above problems, the utility model provides the following technical solution:

[0008] A plywood drying device, including a placement table, support columns are provided on the placement table, a hot air hood is provided on the support columns, a drying chamber is provided in the hot air hood, hot air blowers are provided on both sides of the hot air hood, a number of hot air channels are provided between the drying chamber and the hot air hood, a number of hollow holes are provided on the drying chamber body, one end of the hot air channel is connected to the hollow hole, and the other end is connected to the inside of the hot air hood, and a gas pipeline is provided between the hot air blower and the hot air hood.

[0009] Furthermore, the hot air hood is in the shape of a hollow cylinder, an air cavity is provided inside the hot air hood body, and one end of the hot air channel passes through the inner wall of the hot air hood and extends into the air cavity.

[0010] Furthermore, one end of the gas pipeline is connected to the hot air hood and extends into the air cavity, and the other end is connected to the hot air blower.

[0011] Furthermore, the drying cabin is in a hollow cylindrical shape, and the drying cabin is fixed to the inside of the hot air hood through the hot air channel, and the hot air channel is made of metal.

[0012] Furthermore, a plurality of the hollow holes and the hot air channels are provided along the surface of the drying chamber, and a dustproof mesh cover is provided at the air inlet of the hot air blower.

[0013] (III) Beneficial effects

[0014] The beneficial effects of the utility model are:

[0015] The plywood that has been cut but not dried is placed in the drying chamber. At this time, the plywood is in a rectangular plate shape. The plywood is placed through the cylindrical inner wall of the drying chamber. The circular structure of the drying chamber allows the inner wall of the drying chamber to support plywood of different sizes, that is, when the width of the plywood is larger, it is closer to the center of the circle with a larger diameter for easy placement, while the width of the plywood is smaller and it slides down to the bottom. The arc-shaped structure can accommodate plywood of different sizes, which is highly versatile and does not require contact between both sides of the plywood. The plywood is clamped by the side wall, which increases the contact area during the drying process, enhances the drying effect, and is covered in many aspects through the hot air channel without the need to flip the board surface.
