Description

Technical Field

[0001] This utility model relates to the technical field of wood microwave drying equipment, specifically to a wood microwave drying device. Background Technology

[0002] Microwave drying is a novel method for drying wood. Wood is placed in a microwave electromagnetic field, and the electromagnetic loss caused by the interaction between microwaves and the moisture in the wood is converted into heat energy, thus heating the wood. During the drying process, the moisture content of the wood is higher inside and lower outside, so its absorption of microwave energy gradually decreases from the inside out, resulting in a uniform temperature and moisture content gradient throughout the wood. During microwave drying, as long as the wood is within the microwave penetration range, it is heated simultaneously, and the thickness of the wood has no significant impact on the drying rate. Patent number CN202220229200.4 discloses a microwave device for wood drying. After the wood is microwaved, it is rolled during transport by a roller pressing device, which can effectively prevent edge deformation. However, during the use of the microwave drying equipment, the wood is rolled when removed from the equipment. When a single active roller rolls the dried wood from above, the wood is prone to slight bending upwards, which can have a certain impact on the wood. Therefore, we propose a microwave drying device for wood. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a microwave drying device for wood.

[0004] The technical solution adopted by this utility model to solve its technical problem is a microwave drying device for wood, including a microwave drying equipment body. The outer end surface of the microwave drying equipment body is equipped with a base for support, and the outer periphery of the base is equipped with U-shaped seats for auxiliary support by bolts. There are two sets of U-shaped seats. The inner side of the U-shaped seats is slidably installed with sliding columns for adjustment. There are multiple sets of sliding columns. The inner side of the U-shaped seats is equipped with hydraulic rods for pushing the sliding columns to move. There are multiple sets of hydraulic rods. The multiple sets of sliding columns are equipped with supports corresponding to the U-shaped seats. There are two sets of supports. The top surface of the supports is equipped with studs for limiting. There are multiple sets of studs. The outer periphery of the studs is equipped with ring seats for adjustment. The multiple sets of ring seats are equipped with top frames corresponding to the base. The inner side of the top frame is rotatably installed with pressure rollers for wood pressing. There are multiple sets of pressure rollers. The inner side of the base is rotatably installed with guide rollers for guiding materials. There are multiple sets of guide rollers.

[0005] A disc base for auxiliary support is screwed onto the outer periphery of the stud, and a compression spring for pushing the disc base to move is assembled between the disc base and the ring base. A rubber ring for protection is glued to the bottom surface of the ring base.

[0006] By adopting the above technical solution, when the wood is removed from the main body of the microwave drying equipment, it will enter the multiple sets of guide rollers on the surface of the base. The multiple sets of pressure rollers inside the top frame can simultaneously roll the wood and reduce the bending of the wood. Moreover, the multiple sets of pressure rollers can make the wood more evenly stressed, thereby further reducing the bending deformation of the wood during the rolling process.

[0007] During the use of the microwave drying equipment for wood, multiple sets of hydraulic rods inside the U-shaped base can operate and push the support to move. The support, in turn, drives the ring seat to move up and down through the stud, which facilitates the adjustment of the distance between the top frame and the base. It is also convenient to adjust the distance between the guide roller and the pressure roller according to the thickness of the wood. At the same time, the disc seat on the outer periphery of the stud provides a counter-thrust force for the compression spring, so that the compression spring can apply pressure to the ring seat. This allows the ring seat to drive the top frame and its internal pressure roller to stably roll the wood conveyed on the surface of the guide roller. The rubber ring at the bottom of the ring seat helps to reduce the damage caused by friction when the ring seat and the support come into contact, so that the ring seat can be used more stably.

[0008] Specifically, the stud has an arc-shaped groove on its outer periphery that matches the inner periphery of the ring seat, and there are multiple sets of arc-shaped grooves.

[0009] By adopting the above technical solution, the arc-shaped groove on the outer periphery of the stud and the protrusion on the inner periphery of the ring seat fit together, which facilitates the improvement of the stability of the ring seat when it slides on the outer periphery of the stud.

[0010] Specifically, the inner side of the arc-shaped groove is provided with pin holes for limiting the position, and there are multiple sets of pin holes. The outer periphery of the disc base is screwed with a screw pin that is screwed into the pin hole.

[0011] By adopting the above technical solution, after the displacement angle of the outer peripheral disc seat of the stud, the screw pin on the outer periphery of the disc seat can be rotated and the end of the screw pin passing through the disc seat can be screwed into the pin hole inside the arc groove, which facilitates further locking and fixing of the position of the outer peripheral disc seat of the stud, so that the disc seat can more stably support the compression spring and facilitate the subsequent application of counter-thrust force to it.

[0012] Specifically, the inner side of the support is fitted with a sliding sleeve for limiting the position, and the top surface of the U-shaped seat is fitted with a vertical rod that is inserted and connected to the sliding sleeve.

[0013] By adopting the above technical solution, the vertical rod on the surface of the U-shaped seat and the sliding sleeve on the support are interlocked and slidably connected, which facilitates the improvement of the stability of the top support of the U-shaped seat during lifting and lowering displacement.

[0014] Specifically, the outer wall surface of the base is equipped with a controller that is electrically connected to the hydraulic rod.

[0015] By adopting the above technical solution, the controller can easily control the operation of the hydraulic rod, making the main body of the microwave drying equipment more convenient to use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of the base, guide rollers, top frame and pressure rollers, allows the wood to enter the multiple sets of guide rollers on the surface of the base when it is removed from the main body of the microwave drying equipment during the use of the wood microwave drying equipment. The multiple sets of pressure rollers inside the top frame can simultaneously roll the wood and reduce the bending of the wood. Moreover, the multiple sets of pressure rollers can make the wood more evenly stressed, thereby further reducing the bending deformation of the wood during the rolling process.

[0018] 2. The technical solution of this application, through the design of a U-shaped seat, sliding column, hydraulic rod, support, stud, ring seat, disc seat, rubber ring, and compression spring, enables multiple sets of hydraulic rods inside the U-shaped seat to operate and push the support to move during the use of the wood microwave drying equipment. The support, in turn, drives the ring seat to move up and down through the stud, facilitating the adjustment of the distance between the top frame and the base. This allows for easy adjustment of the distance between the guide roller and the pressure roller according to the thickness of the wood. At the same time, the disc seat on the outer periphery of the stud provides a counter-thrust force for the compression spring, enabling the compression spring to apply pressure to the ring seat. This allows the ring seat to drive the top frame and its internal pressure roller to stably roll the wood conveyed on the surface of the guide roller. The rubber ring at the bottom of the ring seat helps reduce damage caused by friction when the ring seat and the support come into contact, making the ring seat more stable in use.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a microwave drying device for wood, including a microwave drying equipment body 1. A base 2 for support is mounted on the outer end surface of the microwave drying equipment body 1, and U-shaped seats 3 for auxiliary support are bolted to the outer periphery of the base 2. There are two sets of U-shaped seats 3. Multiple sets of sliding columns 4 are slidably installed on the inner side of the U-shaped seats 3. Multiple sets of hydraulic rods 5 are mounted on the inner side of the U-shaped seats 3 to push the sliding columns 4 to move. Supports 6 corresponding to the U-shaped seats 3 are mounted between the multiple sets of sliding columns 4. There are two sets of supports 6. The top surface is fitted with studs 7 for limiting, and there are multiple sets of studs 7. An adjusting ring seat 8 is installed on the outer periphery of the studs 7, and a top frame 9 corresponding to the base 2 is assembled between the multiple sets of ring seats 8. A pressure roller 10 for wood rolling is rotatably installed on the inner side of the top frame 9, and there are multiple sets of pressure rollers 10. A guide roller 11 for guiding material is rotatably installed on the inner side of the base 2, and there are multiple sets of guide rollers 11. A disc seat 13 for auxiliary support is screwed onto the outer periphery of the studs 7, and a compression spring 14 for pushing the disc seat 13 to move is assembled between the disc seat 13 and the ring seat 8. A protective rubber ring 18 is glued to the bottom surface of the ring seat 8.

[0026] When the wood is removed from the main body 1 of the microwave drying equipment, it will enter the multiple sets of guide rollers 11 on the surface of the base 2. The multiple sets of pressure rollers 10 inside the top frame 9 can simultaneously roll the wood and reduce the bending of the wood. The multiple sets of pressure rollers 10 can make the wood more evenly stressed, thereby further reducing the bending deformation of the wood during the rolling process.

[0027] During the use of the microwave drying equipment for wood, the multiple sets of hydraulic rods 5 inside the U-shaped base 3 can operate and push the support 6 to move. The support 6 then drives the ring seat 8 to move up and down through the stud 7, which facilitates the adjustment of the distance between the top frame 9 and the base 2. It is also convenient to adjust the distance between the guide roller 11 and the pressure roller 10 according to the thickness of the wood. At the same time, the disc seat 13 on the outer periphery of the stud 7 provides a counter-thrust force for the compression spring 14, so that the compression spring 14 can apply pressure to the ring seat 8, and the ring seat 8 can drive the top frame 9 and the internal pressure roller 10 to steadily roll the wood conveyed on the surface of the guide roller 11. The rubber ring 18 at the bottom of the ring seat 8 helps to reduce the damage caused by the friction when the ring seat 8 and the support 6 come into contact, so that the ring seat 8 can be used more stably.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the stud 7 has an arc-shaped groove 15 on its outer periphery that matches the inner periphery of the ring seat 8, and there are multiple sets of arc-shaped grooves 15.

[0029] When in use, the arc-shaped groove 15 on the outer periphery of the stud 7 matches the protrusion on the inner periphery of the ring seat 8, which helps to improve the stability of the ring seat 8 when it slides on the outer periphery of the stud 7.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the inner side of the arc-shaped groove 15 is provided with pin holes 16 for limiting, and there are multiple sets of pin holes 16. The outer periphery of the disc base 13 is screwed with a screw pin 17 that is screwed into the pin hole 16.

[0031] In use, after the displacement angle of the outer peripheral disc 13 of the screw stud 7, the screw pin 17 on the outer periphery of the disc 13 can be rotated so that one end of the screw pin 17 passing through the disc 13 can be screwed into the pin hole 16 inside the arc groove 15, which facilitates further locking and fixing of the position of the outer peripheral disc 13 of the screw stud 7, so that the disc 13 can more stably support the compression spring 14, and facilitates the subsequent application of counter-thrust force to it.

[0032] like Figure 1 and Figure 2 As shown, the inner side of the support 6 is equipped with a sliding sleeve 19 for limiting the position, and the top surface of the U-shaped seat 3 is equipped with a vertical rod 20 that is inserted and connected to the sliding sleeve 19.

[0033] When in use, the vertical rod 20 on the surface of the U-shaped base 3 and the sliding sleeve 19 on the support 6 are inserted into each other and slidably connected, which facilitates the improvement of the stability of the top support 6 of the U-shaped base 3 when it is raised or lowered.

[0034] like Figure 1 As shown, a controller 12 electrically connected to the hydraulic rod 5 is mounted on the outer wall surface of the base 2.

[0035] In use, the controller 12 facilitates the operation of the hydraulic rod 5 and makes the main body 1 of the microwave drying equipment more convenient to use.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in suitable positions. During the use of the wood microwave drying equipment, the controller 12 can operate the multiple sets of hydraulic rods 5 inside the U-shaped base 3, pushing the support 6 to move. The support 6, through the stud 7, drives the ring seat 8 to move up and down, facilitating the adjustment of the distance between the top frame 9 and the base 2. This allows for easy adjustment of the distance between the guide roller 11 and the pressure roller 10 according to the thickness of the wood. Simultaneously, the disc seat 13 on the outer periphery of the stud 7 provides a counterforce to the compression spring 14, enabling the compression spring 14 to apply pressure to the ring seat 8, thus allowing the ring seat 8 to stably drive the top frame 9 and its internal pressure roller 10. The wood conveyed on the surface of the guide roller 11 is rolled, and the rubber ring 18 at the bottom of the ring seat 8 helps to reduce the damage caused by friction when the ring seat 8 and the support 6 come into contact, so that the ring seat 8 can be used more stably. At the same time, when the wood is removed from the microwave drying equipment body 1, it will enter the multiple sets of guide rollers 11 on the surface of the base 2. The multiple sets of pressure rollers 10 inside the top frame 9 can roll the wood synchronously and reduce the bending of the wood. The multiple sets of pressure rollers 10 can make the wood more evenly stressed, thereby further reducing the bending deformation of the wood during the rolling process. Then, the drive structure on the outside of the base 2 can adjust the rotation of the guide roller 11 and continuously convey the wood, which is convenient for rolling the next set of wood.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
