Description

Technical Field

[0001] This utility model relates to the field of timber equipment technology, and in particular to a drying device for timber after gluing. Background Technology

[0002] The main purpose of applying glue to timber is to "optimize" and "upgrade" it. Wood is anisotropic and easily shrinks, expands, warps, and deforms due to changes in humidity. Applying glue helps to cancel out internal stresses, significantly reducing the possibility of deformation and cracking, resulting in a more stable finished product. After applying glue, the timber needs to be dried; in the timber industry, this process is more commonly referred to as "aging" or "maturation."

[0003] In existing technologies, common drying methods include natural drying and artificial heating drying. Natural drying involves allowing glued timber to cure naturally in a well-ventilated, room-temperature environment. While low-cost and simple to operate, it is time-consuming and its effectiveness is greatly affected by ambient temperature and humidity. Artificial drying is often used in large-scale production. However, in some drying systems using centralized heat sources, uneven heat distribution can lead to localized overheating of the timber while other areas remain underheated. This can cause timber deformation, uneven bonding strength, and even glue carbonization, affecting product quality. Furthermore, when multiple timbers are dried side-by-side, uneven spacing between them can also result in uneven heat distribution and inconsistent bonding strength. Utility Model Content

[0004] This utility model aims to solve the technical problem of wood deformation and uneven bonding strength caused by uneven heat distribution during the drying process of glued wood squares with concentrated heat source. It provides a drying device for glued wood squares, including a drying table and a connecting bracket connected above the drying table. A telescopic cylinder and a variable frequency fan are fixedly connected to the connecting bracket.

[0005] The piston rod output end of the telescopic cylinder is connected to a heating cover. Multiple parallel partitions are evenly arranged inside the heating cover to form multiple wooden blocks of the same size. An electric heating strip is fixedly installed on the top of each wooden block. One side of the heating cover is open, and multiple square-round diameter joints are fixedly connected to the opening. A pipe is provided between the square-round diameter joints and the variable frequency fan, and the pipes are connected to the variable frequency fan.

[0006] Preferably, in the above technical solution, the drying table is provided with a timber guide rail, which includes a first guide rail and a second guide rail that are parallel to each other.

[0007] Preferably, in the above technical solution, guide rail grooves are provided at the axial positions of both the first guide rail and the second guide rail.

[0008] Preferably, in the above technical solution, multiple pulleys are provided on one side of the first guide rail and on both sides of the second guide rail, and a guide platform is provided at the end of both the first guide rail and the second guide rail. The guide platform is triangular, and its far corner is rounded.

[0009] Preferably, in the above technical solution, the side of the heating cover and the partition are matched with the guide rail groove, and the number of heating strips in each timber compartment is two. The two heating strips are respectively set at the intersection of the partition and the heating cover, and the number of timber compartments corresponds to the number of square-round transition joints.

[0010] Preferably, in the above technical solution, the pipeline includes a main pipeline and multiple branch pipelines connected to the main pipeline. Each end of the main pipeline is provided with a clamp, and two clamps are fixedly connected to the connecting bracket. The air outlet of the variable frequency fan is connected to the center of the main pipeline.

[0011] Preferably, in the above technical solution, the number of branch pipes corresponds to the number of square-round diameter joints, and is connected one-to-one with the square-round diameter joints. The middle section of each branch pipe is a flexible expansion pipe.

[0012] Preferably, in the above technical solution, a connecting plate is provided at the top center of the heating cover, and the piston rod output end of the telescopic cylinder is fixedly connected to the center of the connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention divides the wood into multiple independent drying chambers by setting multiple parallel partitions inside the heating hood and installing heating strips on the sides of the partitions, thus facilitating individual drying of the wood.

Detailed Implementation

[0023] 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.

[0024] like Figures 1-5As shown, this utility model discloses a drying device for wood after gluing, comprising a drying table 1 and a connecting bracket 2 connected above the drying table 1. A telescopic cylinder 4 and a variable frequency fan 5 are fixedly connected to the connecting bracket 2. A heating cover 6 is connected to the piston rod output end of the telescopic cylinder 4. The heating cover 6 is rectangular. A connecting plate 61 is also provided at the center of the top of the heating cover 6, and the piston rod output end of the telescopic cylinder 4 is fixedly connected to the center of the connecting plate 61. The connecting plate 61 increases the connection stability between the piston rod output end of the telescopic cylinder 4 and the heating cover 6, increases the force-bearing area, and prevents the heating cover 6 from falling off. The heating hood 6 has multiple parallel partitions 62 evenly arranged inside, forming multiple identical wood square bins 64. Each wood square bin 64 has a heating strip 63 fixedly installed on its top. One side of the heating hood 6 is open, and multiple square-to-round diameter adapters 65 are fixedly connected to this opening. A pipe 7 connects the square-to-round diameter adapters 65 to the variable frequency fan 5, and the pipe 7 is used to communicate with the variable frequency fan 5. The wood square bins 64 have a strip-shaped structure and an open bottom, facilitating drying of the wood squares. The variable frequency fan 5, connected to the square-to-round diameter adapters 65, blows air into the wood square bins 64, increasing airflow within them.

[0025] It should be further explained that the drying table 1 is provided with timber guide rails 3, which include a first guide rail 31 and a second guide rail 32 that are parallel to each other. The first guide rail 31 is the guide rail set on both sides of the drying table 1, and the second guide rail 32 is the guide rail set between the first guide rail 31. The first guide rail 31 and the second guide rail 32 are both provided with guide rail grooves 33 at their axial positions. The side of the heating cover 6 and the partition 62 are matched with the guide rail grooves 33. Each timber compartment 64 contains two heating bars 63, and the two heating bars 63 are respectively set at the intersection of the partition 62 and the heating cover 6. The number of timber compartments 64 corresponds to the number of square-round transition joints 65. The piston rod output end of the telescopic cylinder 4 is connected to the heating cover 6, driving the heating cover 6 to fall. This causes the two sides of the heating cover 6 and the partition 62 to fall into the guide grooves 33 within the first guide rail 31 and the second guide rail 32. This allows the partition 62, the first guide rail 31, and the second guide rail 32 to cooperate in disassembling the heating cover 6 into multiple identical timber compartments 64. Multiple pulleys 35 are provided on one side of the first guide rail 31 and on both sides of the second guide rail 32. A timber guide platform 36 is provided at the end of both the first guide rail 31 and the second guide rail 32. The timber guide platform 36 is triangular, with rounded corners at its far ends. The pulleys 35 facilitate the entry of timber into the timber compartments 64 and maintain a certain distance from the guide rails and partitions 62, preventing the timber from sticking to the partitions 62, causing excessively high local temperatures, and reducing the local heat flow space. This can lead to uneven heating of the timber, resulting in quality problems such as wood deformation and glue carbonization. The triangular shape of the guide platform 36 helps guide the wood to enter the timber bin 64 more easily, preventing the top of the timber from colliding with the guide platform 36 and causing the feeding to jam.

[0026] In this embodiment, the pipe 7 includes a main pipe 75 and multiple branch pipes 71 connected to the main pipe 75. Each end of the main pipe 75 is equipped with a clamp 76, and two clamps 76 are fixedly connected to the connecting bracket 2. The air outlet of the variable frequency fan 5 is connected to the center of the main pipe 75. The clamps 76 at both ends of the main pipe 75 stably fix the main pipe to the connecting bracket 2, preventing the variable frequency fan 5 from shaking due to excessive airflow and generating noise pollution. The number of branch pipes 71 corresponds to the number of square-to-round diameter joints 65, and each branch pipe 71 is connected to a corresponding square-to-round diameter joint 65. The middle section of each branch pipe 71 is a flexible expansion tube 72. The flexible expansion tube 72 facilitates the contraction and expansion of the pipe section when the square-to-round diameter joint 65 and the heating cover 6 move simultaneously, preventing the connecting pipe section from falling off or breaking, thus affecting the airflow and heat distribution. The number of branch pipes 71 and square-round diameter joints 65 are one-to-one, ensuring that the branch pipes 71 and the timber bins 64 are one-to-one. This allows the timber bins 64 to independently utilize the variable frequency fan 5 to increase the rate of heat distribution and flow, so that the heat of each area of ​​the glued timber is balanced during the drying process. This avoids local overheating, which can lead to timber deformation, uneven bonding strength, and glue carbonization, thus affecting product quality.

[0027] This invention divides the wood into multiple independent drying chambers by installing multiple parallel partitions inside the heating hood and electric heating strips on the sides of the partitions, facilitating individual drying of the wood. A variable frequency fan connected to one end of each chamber ensures more even heat distribution. The guide rail grooves in the wood guide rails engage with the partitions inside the heating hood, and a telescopic cylinder drives the heating hood to move vertically, forming independent and well-sealed wood chambers, achieving uniform drying of the glued wood.

[0028] Although the present invention 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 invention should be included within the protection scope of the present invention.
