Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment furnace technology, specifically a heat treatment furnace for wood packaging materials. Background Technology
[0002] Wood packaging material heat treatment furnaces use high temperatures to kill harmful organisms that may exist in the wood, such as insects and fungi, to ensure the safety of the wood during transportation and storage and to meet phytosanitary requirements.
[0003] In existing heat treatment furnaces for wood packaging materials, the furnace temperature is gradually increased to the treatment temperature through a heating system during the heat treatment process. However, the furnace temperature cannot be adjusted according to the personnel's requirements, resulting in limitations of the equipment. At the same time, the hot airflow inside the equipment is discharged, causing the furnace temperature to be too low. The equipment cannot adjust the furnace's sealing, leading to a decrease in the efficiency of the heating system. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a heat treatment furnace for wood packaging materials, which has the advantages of adjustable heating system and improved furnace sealing, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a heat treatment furnace for wood packaging materials, comprising a furnace body, a third motor fixedly installed at the bottom of the furnace body, a first gear fixedly mounted on the power output shaft of the third motor, a second gear meshing with the outer wall of the first gear, a fan fixedly mounted on the top of the second gear, a heating tube fixedly mounted on the inner wall of the furnace body, a first motor fixedly mounted on the outer wall of the furnace body, a worm gear fixedly mounted on the power output shaft of the first motor, a worm wheel ring meshing with the outer wall of the worm gear, an adjusting plate fixedly mounted on the outer wall of the worm wheel ring, a lead screw rotatably connected to the inner wall of the adjusting plate, a working chamber fixedly mounted on the top of the furnace body, an exhaust port rotatably connected to the outer wall of the working chamber, a lead screw fixedly mounted on the inner wall of the exhaust port, a second motor fixedly mounted on the power output shaft of the lead screw, a sealing plate threadedly connected to the outer wall of the second motor, a temperature sensor fixedly mounted on the outer wall of the sealing plate, and a controller fixedly mounted on the outer wall of the furnace body.
[0006] As a preferred technical solution of this utility model: the controller is electrically connected to the first motor, and the inner walls of the adjusting plate and the lead screw are both provided with through holes.
[0007] As a preferred technical solution of this utility model: the inner wall of the furnace body is provided with a sliding groove, and the inner wall of the sliding groove is rotatably connected to the outer wall of the adjusting plate.
[0008] As a preferred technical solution of this utility model: the controller is electrically connected to the third motor, and the fan is located at the center of the bottom inner wall of the furnace body.
[0009] As a preferred technical solution of this utility model: the controller is electrically connected to the heating tube and the temperature sensor respectively, and there are several heating tubes distributed on the inner wall of the furnace body.
[0010] As a preferred technical solution of this utility model: the controller and the lead screw are electrically connected, and the outer diameter of the sealing plate is larger than the inner diameter of the exhaust port.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This wood packaging material heat treatment furnace, through the control controller, uses the airflow generated by the fan rotation to be converted into hot airflow through the heating tube. The airflow passes through the inner wall of the through hole, causing the material on the inner wall of the working chamber to undergo heat treatment. The first motor drives the worm gear to rotate, and the worm gear drives the adjusting plate to rotate through the worm wheel ring. The adjusting plate causes the through hole to rotate on the outer wall of the screw, thereby creating a misalignment between the through holes and blocking and regulating the airflow at the bottom.
[0013] 2. This heat treatment furnace for wood packaging materials monitors the inner wall temperature of the working chamber through a temperature sensor. When the inner wall reaches a specified value, a signal is transmitted to the lead screw, which drives the sealing plate to move. The sealing plate causes the temperature sensor to detach from the inner wall of the exhaust port, allowing the heat from the working chamber and the inner wall of the furnace to be discharged, improving the sealing performance of the furnace and preventing the temperature from being too low or too high, which would reduce the heating efficiency of the subsequent furnace heat treatment.

[0020] 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.
[0021] Please see Figure 1 - Figure 5 A heat treatment furnace for wood packaging materials includes a furnace body 1. A third motor 12 is fixedly installed at the bottom of the furnace body 1. A first gear 13 is fixedly mounted on the power output shaft of the third motor 12. A second gear 14 meshes with the outer wall of the first gear 13. A fan 11 is fixedly installed on the top of the second gear 14. A heating tube 10 is fixedly installed on the inner wall of the furnace body 1. A first motor 3 is fixedly installed on the outer wall of the furnace body 1. A worm gear 5 is fixedly mounted on the power output shaft of the first motor 3. A worm wheel ring 2 meshes with the outer wall of the worm gear 5. An adjusting plate 16 is fixedly installed on the outer wall of the worm wheel ring 2. A lead screw 9 is rotatably connected to the inner wall of the adjusting plate 16. A working chamber 6 is fixedly installed on the top of the furnace body 1. An exhaust port 7 is rotatably connected to the outer wall of the working chamber 6. A lead screw 9 is fixedly installed on the inner wall of the exhaust port 7. A second motor 8 is fixedly mounted on the power output shaft of the lead screw 9. A sealing plate 17 is threadedly connected to the outer wall of the second motor 8. A temperature sensor 18 is fixedly installed on the outer wall of the sealing plate 17. A controller 4 is fixedly installed on the outer wall of the furnace body 1.
[0022] In the above structure, by installing heating tube 10, heat is generated by heating tube 10, so that the temperature inside the furnace body 1 reaches the temperature required for heat treatment, thereby enabling the material to undergo heat treatment.
[0023] In a preferred embodiment: the controller 4 is electrically connected to the first motor 3, and the inner walls of the adjusting plate 16 and the lead screw 9 are both provided with through holes 19.
[0024] In the above structure, the controller 4 is used to drive the first motor 3 to rotate the worm 5. The worm 5 drives the adjusting plate 16 to rotate through the worm wheel ring 2, so that the adjusting plate 16 drives the through hole 19 to rotate on the outer wall of the worm 5, thereby creating a misalignment between the through holes 19 and blocking and regulating the airflow at the bottom.
[0025] In a preferred embodiment, the inner wall of the furnace body 1 is provided with a sliding groove 15, and the inner wall of the sliding groove 15 is rotatably connected to the outer wall of the adjusting plate 16.
[0026] In the above structure, the inner wall of the slide groove 15 is rotatably connected to the outer wall of the adjusting plate 16. The worm gear ring 2 drives the adjusting plate 16 to rotate on the inner wall of the slide groove 15, so that the adjusting plate 16 drives the lead screw 9 to achieve the limit and avoid the adjustment from being offset.
[0027] In a preferred embodiment: the controller 4 is electrically connected to the third motor 12, and the fan 11 is located at the center of the bottom inner wall of the furnace body 1.
[0028] In the above structure, the first gear 13 is driven to rotate by the third motor 12 through the control controller 4. The outer wall of the first gear 13 meshes with the outer wall of the second gear 14, so that the fan 11 rotates to generate airflow, which is sufficient for the inner wall of the furnace body 1.
[0029] In a preferred embodiment: the controller 4 is electrically connected to the heating tube 10 and the temperature sensor 18 respectively. There are several heating tubes 10, and the several heating tubes 10 are distributed on the inner wall of the furnace body 1.
[0030] In the above structure, the airflow generated by the rotation of the fan 11 is converted into hot airflow through the heating pipe 10, so that the material on the inner wall of the working chamber 6 is heat-treated. By setting the temperature sensor 18, the temperature sensor 18 can monitor the internal temperature of the furnace body 1, so as to avoid the temperature being too high and resulting in poor heat treatment of the material.
[0031] In a preferred embodiment: an electrical connection is formed between the controller 4 and the lead screw 9, and the outer diameter of the sealing plate 17 is larger than the inner diameter of the exhaust port 7.
[0032] In the above structure, the temperature sensor 18 monitors the inner wall temperature of the working chamber 6. When the inner wall reaches the specified value, a signal is transmitted to the lead screw 9. The lead screw 9 drives the sealing plate 17 to move. The sealing plate 17 causes the temperature sensor 18 to detach from the inner wall of the exhaust port 7, so that the heat of the working chamber 6 and the inner wall of the furnace body 1 can be discharged, avoiding the temperature from being too low or too high, which would reduce the heating efficiency of the subsequent heat treatment of the furnace body 1.
[0033] Working principle: The controller 4 uses the third motor 12 to drive the first gear 13 to rotate. The outer wall of the first gear 13 meshes with the outer wall of the second gear 14, causing the fan 11 to rotate and generate airflow, which is sufficient for the inner wall of the furnace body 1. The airflow generated by the fan 11 is converted into hot airflow through the heating pipe 10. The airflow passes through the inner wall of the through hole 19, causing the material on the inner wall of the working chamber 6 to undergo heat treatment. A temperature sensor 18 is installed to monitor the internal temperature of the furnace body 1. If the heat treatment of the material is inadequate, the first motor 3 drives the worm gear 5 to rotate. The worm gear 5... The worm gear ring 2 drives the adjusting plate 16 to rotate, causing the adjusting plate 16 to drive the through hole 19 to rotate on the outer wall of the worm 5, thereby creating a misalignment between the through holes 19 and blocking and regulating the airflow at the bottom. The temperature sensor 18 monitors the inner wall temperature of the working chamber 6. When the inner wall reaches the specified value, a signal is transmitted to the lead screw 9, which drives the sealing plate 17 to move. The sealing plate 17 causes the temperature sensor 18 to detach from the inner wall of the exhaust port 7, allowing the heat from the inner wall of the working chamber 6 and the furnace body 1 to be discharged, avoiding excessively low or high temperatures that would reduce the heating efficiency of the subsequent heat treatment of the furnace body 1.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
