Description

Technical Field

[0001] This utility model relates to the field of plywood technology, specifically to a drying device for plywood processing. Background Technology

[0002] Plywood is a sheet material consisting of three or more layers of veneer, made by rotary cutting logs into veneers or slicing timber into thin sheets, and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the fiber directions of adjacent veneers perpendicular to each other. During plywood production, a drying device is used to dry and dehydrate the plywood. For example, patent application number 202323354572.3, entitled "A Drying Device for Plywood Processing," includes a drying box. A placement plate is fixedly connected to the inner wall of the drying box. A cavity is formed in the side wall of the drying box. A heating element communicating with the cavity is installed at the upper end of the drying box. The device includes two lead screw components connected in a movable manner, with a transmission component between them. This plywood drying device incorporates a heating element. Through the cooperation of a fan and a heating plate, hot air enters the inner side of the cavity via a conveying pipe and then passes through drying holes to uniformly dry the plywood. When the motor is started, it drives the lead screws to rotate. With the cooperation of a transmission wheel and belt, the two lead screws rotate synchronously. The two lead screw seats on the lead screws move synchronously towards the center. This movement of the lead screw seats causes their movable rods to push the pressing plate downwards, pressing the plywood on the plate and thus preventing deformation during drying.

[0003] The aforementioned technologies have the following drawbacks: when drying and dehydrating plywood, the drying device uses an extrusion plate to pressurize and limit the plywood, which reduces the contact area between the plywood and the hot air, thereby reducing the drying time required by the drying device and reducing the working efficiency of the drying device.

[0004] Therefore, it is necessary to redesign and modify the drying equipment to effectively prevent its low drying efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a drying device for plywood processing, which has the advantage of improving the drying efficiency of the drying device and solves the problem of low drying efficiency.

The inner side of the guide block 11 extends into the interior of the guide groove 10. A lubrication mechanism is provided inside the guide groove 10.

[0026] As a technical optimization of this utility model, by setting the guide groove 10 and the guide block 11, the moving plate 8 is guided and limited when it moves up and down, so as to avoid the moving plate 8 from shifting and thus affecting its limitation on the plate body 5.

[0027] refer to Figure 5 The lubrication mechanism includes a mounting groove 12 formed in the inner wall of the guide groove 10. A solid lubricant 13 is fixedly connected inside the mounting groove 12. The outer side of the solid lubricant 13 extends to the outside of the mounting groove 12 and is movably connected to the surface of the guide block 11.

[0028] As a technical optimization of this utility model, by setting the mounting groove 12 and the solid lubricant 13, when the solid lubricant 13 rubs against the guide block 11, the lubricant in the solid lubricant 13 will be transferred to the guide block 11, lubricating the guide block 11 and the moving plate 8, and reducing the wear on the guide block 11 and the moving plate 8.

[0029] refer to Figure 3 The purification mechanism includes an activated carbon filter element 14 fixedly connected to the top of the partition 3. The top of the activated carbon filter element 14 is fixedly connected to the inner wall of the outer shell 1. A vent 15 located outside the activated carbon filter element 14 is opened on the surface of the partition 3. An exhaust port 16 is opened on the top of the outer shell 1. A protective mechanism is provided on the top of the outer shell 1.

[0030] As a technical optimization of this utility model, by setting up a vent 15, an activated carbon filter element 14 and an exhaust port 16, the gas generated during the drying of the board body 5 is filtered, and harmful substances in the gas are adsorbed and purified to avoid pollution to the environment.

A filter screen 18 and a support column 19 are fixedly connected to the inner wall of the protective cover 17. The support column 19 is located on top of the filter screen 18. The inner side of the filter screen 18 and the bottom of the support column 19 are both fixedly connected to the surface of the outer shell 1.

[0032] As a technical optimization of this utility model, by setting up a protective cover 17, a filter screen 18 and a support column 19, debris is blocked, preventing debris from entering the interior of the outer shell 1 through the exhaust port 16 and clogging the activated carbon filter element 14, thus affecting the purification effect of the activated carbon filter element 14.

[0035] The working principle and usage process of this utility model are as follows: When in use, first place the board body 5 into the support frame 6, then start the piston cylinder 7. The piston cylinder 7 drives the moving plate 8 and the limiting frame 9 to move downward through the output end, so that the limiting frame 9 is fitted onto the board body 5. Then close the cabinet door 2, and then start the magnetron 4. The magnetron 4 will release microwaves, which will cause the water molecules in the board body 5 to vibrate and rub at high frequency. The heat generated by the high-frequency vibration and friction will dry the board body 5.

[0036] In summary, this plywood drying device, by setting up a magnetron 4, utilizes the microwaves generated by the magnetron 4 to cause high-frequency vibration and friction of water molecules inside the plywood body 5. The heat generated by the high-frequency vibration and friction is used to dry the plywood body 5. The support frame 6, piston cylinder 7, moving plate 8, and limiting frame 9 limit the plywood body 5, allowing most of the plywood body 5 to contact the air, thus accelerating the drying speed of the plywood body 5 and improving the drying efficiency of the drying device.
