Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to a hot air circulating oven that is easy to adjust. Background Technology

[0002] The drying oven is an industrial drying equipment made of welded steel profiles and thin plates. It is mainly used in industrial and scientific research fields such as material drying, resin curing, pharmaceuticals, and electronic component processing. Its box structure combines sturdiness and aesthetics. The working chamber is equipped with sample shelves or mobile carts. The space between the outer shell and the working chamber is filled with insulation materials such as aluminum silicate fiber and polyester foam to improve heat insulation performance. Forced air convection is achieved through a blower to ensure temperature uniformity, and air circulation is regulated by a valve on the top of the blower.

[0003] As disclosed in the authorization announcement number CN220524493U, an adjustable hot air circulating oven includes an oven body and a placement plate. Adjustment rods are fixedly installed on both sides of the oven body. Fixing components are provided on both sides of one end of the placement plate. A positioning groove is opened on one side of the adjustment rod of the oven body. A central component is provided at the bottom of the oven body. A rotation hole is opened at one end of the oven body. Although it facilitates the adjustment of the placement plate position, making it easier to place larger materials on the placement plate and improving the subsequent drying efficiency of the materials, the drying process is carried out by the operation of the oven body. After the oven body has finished drying the materials, there will be a lot of waste residue at the bottom of the oven body. The waste residue is concentrated at the outlet of the oven body by the operation of the centralized component, making it easier for the staff to remove the waste residue from the oven body, thereby improving the subsequent drying efficiency of the materials. However, this does not solve the problem that existing ovens of this type are generally not conducive to the convenient conveying and uniform drying of materials, which affects the labor intensity of workers, the efficiency of conveying and uniformly drying materials, and the efficiency of circulating air in the oven.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable hot air circulating oven, comprising a frame and an oven body. The oven body is installed inside the frame, a first double-speed chain is installed at the top of the frame, three sets of trays are arranged outside the first double-speed chain, a support frame is arranged outside the frame, a first infrared sensor is installed on the side wall of the first double-speed chain, a display control panel is installed on the side wall of the support frame, a temperature controller is installed on the side wall of the support frame above the display control panel, a second double-speed chain is installed inside the oven body, and the surfaces of both the first and second double-speed chains are symmetrically provided with grooves. A rotating shaft is symmetrically installed on both sides of the disc. Rollers are fitted on the surface of each rotating shaft and are slidably connected to a sliding groove. A movable bracket is installed on the inner wall of the support frame. A stepper motor is installed at the top of the movable bracket. A first threaded rod is installed at the output end of the stepper motor. The first threaded rod extends into the interior of the movable bracket and is movably connected thereto.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the oven not only realizes the convenient conveying and uniform drying of materials, reducing the labor intensity of manual labor and improving the efficiency of conveying and uniformly drying materials, but also realizes the convenient circulating air blowing of the oven, improving the efficiency of circulating air blowing of the oven. When using an easily adjustable hot air circulating oven, materials are placed sequentially on the surfaces of three sets of trays. The first speed chain is activated, and supported by the frame, it drives the trays to move. The sliding support of the rollers and chutes ensures stable transport of the trays. When a tray moves to one side of the first speed chain, the first infrared sensor detects it and transmits a signal to the display control panel. This control panel activates the stepper motor, which, supported by a moving bracket, drives the first threaded rod to rotate. The threaded connection between the first threaded rod and the first threaded sleeve causes the first threaded rod to move the first threaded sleeve upwards. The sliding connection between the slider and the slide rail causes the first threaded sleeve to move the conveyor and slider downwards. The conveyor moves upwards. When it moves to be level with the first double-speed chain, it is turned on, causing the first double-speed chain to move the tray on its surface to the surface of the conveyor. When the tray is on the surface of the conveyor, the second infrared sensor senses it and transmits a signal to the display control panel. The display control panel is then turned off to shut down the conveyor and the stepper motor is turned on in reverse, causing the conveyor to descend to be level with the second double-speed chain. The conveyor is then turned on in reverse, causing the tray on its surface to be transported to the surface of the second double-speed chain. The second double-speed chain is then turned on, allowing it to transport the tray to one side of the oven body. This allows for convenient and unified material transport and drying within the oven, reducing manual intervention and improving the efficiency of material transport and drying within the oven. When drying is required, multiple servo motors are activated. Supported by the oven body and bearing seats, the servo motors drive the second threaded rod to rotate. The threaded connection between the second threaded rod and the second threaded block causes the second threaded rod to move upwards, which in turn moves the two side plates upwards, sealing them against the oven body. Three fans are activated, and the heating block is turned on, allowing the fans to blow air through the tray and material conveyor to the bottom. The air is then transported through the conveying hose to the inside of the fans for further blowing and heating by the heating block. When the temperature sensor detects that the internal temperature of the oven body is too low, it transmits a signal to the display control panel. The control panel then activates the temperature controller, which controls the temperature of the heating block. This enables convenient and efficient air circulation within the oven, facilitating temperature control and improving the overall efficiency of the air circulation process.

The sliding rails 17 are symmetrically installed on the inner wall of the outer support frame 5 of the movable bracket 12, and the sliders 18 are all slidably connected to the sliding rails 17. When using an easily adjustable hot air circulating oven, materials are placed sequentially on the surfaces of three sets of trays 4. The first double-speed chain 3 is activated, and supported by the frame 1, it drives the trays 4 to move. With the sliding support of the rollers 9 and the chute 10, the trays 4 are stably conveyed. When the trays 4 move to one side of the first double-speed chain 3, the first infrared sensor 28 detects them and transmits a signal to the display control panel 6. The control panel 6 then activates the stepper motor 13. Supported by the moving bracket 12, the stepper motor 13 drives the first threaded rod 14 to rotate. Through the threaded connection between the first threaded rod 14 and the first threaded sleeve 15, the first threaded rod 14 moves the first threaded sleeve 15 upwards. Through the sliding connection between the slider 18 and the slide rail 17, the first threaded sleeve 15 drives the conveyor 16 and the slider 18 to move upwards. The conveyor 16 moves upward. When it is aligned with the first double-speed chain 3, the conveyor 16 is turned on, causing the first double-speed chain 3 to move its tray 4 to the surface of the conveyor 16. When the tray 4 is on the surface of the conveyor 16, the second infrared sensor 29 senses it and transmits a signal to the display control panel 6. The display control panel 6 is then turned off to shut down the conveyor 16 and the stepper motor 13 is turned on in reverse, causing the conveyor 16 to descend to be aligned with the second double-speed chain 11. The conveyor 16 is then turned on in reverse, causing its tray 4 to be transported to the surface of the second double-speed chain 11. The second double-speed chain 11 is then turned on, allowing it to transport the tray 4 to one side of the oven body 2. This allows for convenient and unified material transport and drying within the oven, reducing manual intervention and improving the efficiency of material transport and drying within the oven. Servo motors 19 are symmetrically installed on the top side wall of the oven body 2.

Three sets of fans 24 with equal spacing are installed at the top of the oven body 2, and three sets of conveying hoses 25 with equal spacing are installed at the bottom of the oven body 2. Three sets of heating blocks 26 with equal spacing are installed on the outer wall of the oven body 2. The conveying hoses 25 all pass through the heating blocks 26 and are connected to the fan 24. Temperature sensors 27 are symmetrically installed on the inner wall of the oven body 2. The output end of the display control panel 6 is electrically connected to the input ends of the first double speed chain 3, temperature controller 7, second double speed chain 11, stepper motor 13, conveyor 16, servo motor 19, fan 24, heating block 26, temperature sensor 27, first infrared sensor 28, and second infrared sensor 29. When drying is required, multiple servo motors 19 are turned on. Supported by the oven body 2 and bearing seat 22, the servo motors 19 drive the second threaded rod 20 to rotate. With the threaded connection between the second threaded rod 20 and the second threaded block 21, the second threaded rod 20 drives the second threaded block 21 to move upward. The second threaded block 21 drives the two sets of side plates 23 to move upward, so that the two sets of side plates 23 contact the oven body 2 and seal it. Three sets of fans 24 are turned on, and the heating block 26 is turned on, so that the fans 24 blow air. The blown air passes through the tray 4 and the material conveyor to the bottom, and is transported to the inside of the fans 24 through the conveying hose 25 for blowing. The heating block 26 heats the air. When the temperature sensor 27 detects that the internal temperature of the oven body 2 is too low, it transmits the signal to the display control panel 6.

[0018] Working Principle: When using an easily adjustable hot air circulating oven, materials are placed sequentially on the surfaces of three sets of trays 4. The first double-speed chain 3 is activated. Supported by the frame 1, the first double-speed chain 3 drives the trays 4 to move. With the sliding support of the rolling wheels 9 and the slide rails 10, the trays 4 are stably conveyed. When the trays 4 move to one side of the first double-speed chain 3, the first infrared sensor 28 senses the trays 4 and transmits a signal to the display control panel 6. The display control panel 6 then activates the stepper motor 13. Supported by the moving bracket 12, the stepper motor 13 drives the first threaded rod 14 to rotate. With the threaded connection between the first threaded rod 14 and the first threaded sleeve 15, the first threaded rod 14 drives the first threaded sleeve 15 to move upward. With the sliding connection between the slider 18 and the slide rail 17, the first threaded sleeve 15 drives the conveyor 16 and the slider 18 to move upward. When the conveyor 16 moves to be flush with the first double-speed chain 3, the conveyor 16 is opened, causing the first double-speed chain 3 to move its surface tray 4 to the surface of the conveyor 16. When it moves to the surface of the conveyor 16, the second infrared sensor 29 senses the tray 4 and transmits a signal to the display control panel 6, which then operates the display control panel. Plate 6 closes the conveyor 16, and reverses the stepper motor 13, causing the conveyor 16 to descend until it is flush with the second double-speed chain 11. The conveyor 16 then reverses its operation, transporting the tray 4 on its surface to the surface of the second double-speed chain 11. The second double-speed chain 11 then transports the tray 4 to one side of the oven body 2. The servo motor 19 drives the second threaded rod 20 to rotate. With the threaded connection between the second threaded rod 20 and the second threaded block 21, the second threaded rod 20 drives the second threaded block 21 to move upwards. The second threaded block 21 then drives the two sets of side plates 2... 3. Move upwards so that the two sets of side plates 23 come into contact with the oven body 2 and close. Turn on the three sets of fans 24 and the heating block 26 so that the fans 24 blow air. The blown air passes through the tray 4 and the material conveyor to the bottom. It is then conveyed to the inside of the fans 24 through the conveying hose 25 and heated by the heating block 26. When the temperature sensor 27 detects that the internal temperature of the oven body 2 is too low, it transmits the signal to the display control panel 6. The display control panel 6 is operated to turn on the temperature controller 7. The temperature controller 7 controls the temperature of the heating block 26 to complete the operation of the oven.
