Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution, including an oven 1 and two filter plates 15. An air supply box 2 is connected to the top of the oven 1. Two vertical plates 3 are connected inside the air supply box 2, dividing the interior of the oven 1 into three cavities. A fan 4 is connected to one side of each of the two vertical plates 3. Multiple strip-shaped through holes 5 are opened on both sides of the oven 1 at the second cavity position. Air ducts 6 are connected to both the left and right sides of the oven 1. An air outlet pipe 7 is connected to one end of each of the two air ducts 6, and both ends of the two air outlet pipes 7 extend into the oven cavity. Inside the oven 1, two heaters 8 are connected to the front surface of the oven 1, and the output ends of the two heaters 8 extend into the first and third cavities respectively. Two air outlet pipes 7 are connected to the flow diversion components 9 at both ends. Two guide slides 10 are opened at the bottom of the oven 1. A connecting slider 11 is slidably installed inside the guide slide 10. A shelf 12 is connected to the top of the connecting slider 11. A magnet 13 is connected to one end of the guide slide 10. Multiple electric heating tubes 14 are connected to both sides of the inner wall of the oven 1.

[0017] The flow distribution assembly 9 includes four connecting rods 91 connected inside the air outlet duct 7. Bearings 92 are connected between the four connecting rods 91. A rotating rod 93 is connected to the inner ring of the bearing 92. The top of the rotating rod 93 is tapered with its sharp end facing upward. A turbofan 94 is connected to the top surface of the rotating rod 93 close to its tip. Four flow distribution plates 95 are connected to the surface of the rotating rod 93 inside the oven 1. The function of the flow distribution plate 95 is that when the fan 4 delivers outside air to the air outlet duct 7 through the air supply duct 6, the power generated by the air flow will drive the turbofan 94 to rotate. The rotation of the turbofan 94 will in turn drive the rotating rod 93 to rotate within the bearing 92. The rotation of the rotating rod 93 will cause the four flow distribution plates 95 on its surface to rotate as well. The rotation of the flow distribution plates 95 can split and disperse the airflow blown out of the air outlet duct 7, so that the airflow is more evenly distributed inside the oven 1, thereby ensuring that the temperature in various positions inside the oven 1 is more uniform, which is conducive to the curing of the resin and improves the curing effect.

[0018] The air supply box 2 has insertion slots on both the front and rear sides at the top, above the second cavity. Two filter plates 15 are inserted into the second cavity of the air supply box 2 through the insertion slots and fit against the inner side of the strip-shaped through hole 5. A lifting handle 16 is connected to the top of the filter plate 15. Its function is to filter the air entering the air supply box 2 when necessary. The two filter plates 15 can be inserted into the second cavity of the air supply box 2 through the insertion slots, so that the filter plates 15 fit against the inner side of the strip-shaped through hole 5. In this way, the outside air will be filtered by the filter plates 15 as it enters the second cavity of the air supply box 2 through the strip-shaped through hole 5, removing dust and other impurities from the air and ensuring the cleanliness of the air entering the oven 1, which is beneficial to the resin curing process. The lifting handle 16 connected to the top of the filter plate 15 makes it easy to pull the filter plate 15 out of the air supply box 2 when cleaning or replacement is needed.

[0019] The top of the oven 1 is connected to exhaust pipes 17 on both sides of the air supply box 2. Each exhaust pipe 17 is equipped with a solenoid valve 18. The function of the solenoid valve 18 is to open when the resin curing process inside the oven 1 is complete or when the internal air pressure needs to be adjusted, allowing the gas inside the oven 1 to be discharged through the exhaust pipe 17. This ensures stable internal air pressure and also helps to remove any odors or other gases that may be present inside the oven 1, improving the working environment. When venting is not required, the solenoid valve 18 is closed to prevent untreated outside air from entering the oven 1 and affecting the resin curing effect.

[0020] Two sets of temperature sensors 19 are connected to the upper half of the front side of the oven 1. Below the temperature sensors 19, two door panels 20 are hinged to the front of the oven 1. Each door panel 20 has a rotating handle 21 connected to one side, and a transparent observation window 22 is provided above the rotating handle 21 on one side of each door panel 20. The purpose of the window 22 is to allow the temperature sensors 19 to monitor the internal temperature of the oven 1 in real time and feed the temperature information back to the constant temperature control system. This allows the constant temperature control system to accurately adjust the internal temperature of the oven 1 according to the preset temperature, ensuring that the resin curing process takes place in a suitable temperature environment. The hinged door panels 20 are conveniently located on the front of the oven 1 for easy opening when resin samples need to be placed in or removed. The rotating handle 21 makes opening and closing the door panels 20 more convenient and effortless. The transparent observation window 22 allows the operator to directly observe the curing process of the resin inside the oven 1 without opening the door panels 20, enabling timely monitoring of the curing progress and avoiding frequent opening of the door panels 20, which could allow outside air to enter and affect the curing effect, as well as cause heat loss.

[0021] One of the door panels 20 has a controller 23 connected to the right of the rotating handle 21. The controller 23 is electrically connected to the electric heating element 14, the solenoid valve 18, and the temperature sensor 19. Its function is to receive temperature information from the temperature sensor 19 and adjust the heating power of the electric heating element 14 according to preset temperature parameters to maintain a constant internal temperature of the oven 1. Simultaneously, the controller 23 can also control the opening and closing of the solenoid valve 18, precisely regulating the gas flow rate within the oven 1 to provide suitable environmental conditions for resin curing. Operators can conveniently set and adjust the operating parameters of the oven 1 through the controller 23, improving operational convenience and the controllability of the curing process.

[0022] The bottom of the oven 1 is connected to four support legs 24, which are arranged in a rectangular shape. Their function is to provide stable support for the oven 1, ensuring that the oven 1 remains stable during operation and preventing shaking or tilting due to uneven ground or external forces, thereby ensuring the stability and reliability of the resin curing process.

[0023] Working principle: First, the resin sample to be cured is placed on the placement plate 12. Since the placement plate 12 is slidably positioned in the guide groove 10 via the connecting slider 11, it can be easily pushed into the oven 1. The magnet 13 at one end of the guide groove 10 can provide a certain degree of adsorption and positioning for the connecting slider 11, preventing the placement plate 12 from moving randomly during operation. Then, the two door panels 20 are closed and locked by rotating the handle 21. At this time, the internal condition of the oven 1 can be observed through the transparent observation window 22. The fan 4 is started, and the fan 4 draws outside air into the second cavity of the air supply box 2 through the strip-shaped through-hole 5. During the air entry process, it will be filtered by the filter plate 15 to remove dust and other impurities, ensuring the cleanliness of the air entering the oven 1. Filtered air is delivered to the outlet duct 7 through the air duct 6. The power generated by the airflow drives the turbofan 94 to rotate. The turbofan 94 drives the rotating rod 93 to rotate within the bearing 92. The four diverter plates 95 on the surface of the rotating rod 93 also rotate accordingly, diverting and dispersing the airflow blown out of the outlet duct 7, making the airflow more evenly distributed inside the oven 1. At the same time, the heater 8 and the electric heating tube 14 are activated. The output end of the heater 8 extends into the first and third cavities, and the electric heating tube 14 is located on the left and right sides of the inner wall of the oven 1. Together, they heat the inside of the oven 1, raising the temperature inside the oven 1. The temperature sensor 19 monitors the temperature inside the oven 1 in real time and feeds the temperature information back to the controller 23. The controller 23 adjusts the heating power of the electric heating tube 14 according to the preset temperature parameters to maintain a constant temperature inside the oven 1. When the resin curing process is complete inside oven 1 or when internal air pressure needs to be adjusted, controller 23 controls solenoid valve 18 to open, allowing the gas inside oven 1 to be discharged through exhaust pipe 17, ensuring stable internal air pressure and removing any potential odors. When venting is not required, solenoid valve 18 is closed to prevent untreated outside air from entering oven 1. Throughout the resin curing process, operators can easily set and adjust the operating parameters of oven 1 using controller 23, improving operational convenience and controllability of the curing process.
