Technical Field
[0001] This utility model relates to the field of hot air circulating oven technology, and in particular to a hot air circulating oven with temperature feedback control. Background Technology
[0002] In the industrial production field, hot air circulating ovens with temperature feedback control are widely used in processes such as material drying, curing, and sterilization due to their precise temperature control capabilities. The working principle is as follows: the heating device generates hot air, the fan forms a circulating airflow inside the oven, the temperature sensor collects the temperature data inside the oven in real time and feeds it back to the control system, dynamically adjusts the heating power, maintains a stable temperature inside the oven, and ensures the quality of material processing.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the internal shelves of existing temperature feedback controlled hot air circulating ovens are usually placed directly on the placement blocks inside the oven, lacking a stable fixing structure, which makes the shelves prone to swaying left and right during use, thus affecting the drying uniformity and stability of the materials inside the oven. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing temperature feedback control hot air circulation ovens often have the shelf panels placed directly on the placement blocks inside the oven, which lacks a stable fixing structure and is prone to swaying left and right during use, affecting the uniformity and stability of material drying. Therefore, we propose a hot air circulation oven with temperature feedback control.
[0005] To achieve the above objectives, this application adopts the following technical solution: a hot air circulating oven with temperature feedback control, comprising a temperature feedback control hot air circulating oven: a door is installed at one end of the temperature feedback control hot air circulating oven, multiple fixed plates are fixedly connected to both sides of the inner cavity of the temperature feedback control hot air circulating oven, a shelf plate is slidably connected to the top of the fixed plate, a through groove is opened on the top of the fixed plate, a plug rod is slidably connected inside the through groove, an adjustment plate is fixedly connected to the bottom of the plug rod, a return spring is fixedly connected to the top of the adjustment plate, the top of the return spring is fixedly connected to the bottom of the fixed plate, and two plug grooves are opened at the bottom of the shelf plate.
[0006] Preferably, the surface of the plug rod is slidably connected to the inside of the plug groove, and the outer diameter of the plug rod is adapted to the inner diameter of the plug groove.
[0007] Preferably, the top of the plug rod has an arc-shaped surface.
[0008] Preferably, the top of the fixing plate has a limiting groove, and the bottom of the shelf plate is fixedly connected to two limiting blocks, the surface of the limiting blocks being slidably connected to the inside of the limiting groove.
[0009] Preferably, one end of the inner cavity of the limiting groove is provided with a slot, a thrust spring is fixedly connected inside the slot, a thrust block is fixedly connected to one end of the thrust spring, and one end of the thrust block abuts against one end of the limiting block.
[0010] Preferably, sliding grooves are provided on both sides of the inner cavity of the slot, and sliders are fixedly connected to both sides of the thrust block, with the surface of the sliders slidingly connected to the inside of the sliding grooves.
[0011] The technical effects and advantages of this utility model are as follows: In this invention, the shelf is placed on top of a fixed plate. Then, by moving an adjusting plate, the adjusting plate moves the connecting rod, which slides inside the through slot until it reaches the slot. The return spring's own elasticity pushes the adjusting plate, which in turn moves the connecting rod, causing its surface to slide into the slot until it is fully inserted. At this point, the shelf is fixed in position, making it more stable inside the temperature-controlled hot air circulation oven. This prevents the oven from wobbling or tilting during operation, ensuring the drying effect of the items inside the oven. Attached Figure Description

[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.
[0015] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a hot air circulating oven with temperature feedback control, including a temperature feedback control hot air circulating oven 1: a door 16 is installed at one end of the temperature feedback control hot air circulating oven 1, and multiple fixed plates 2 are fixedly connected to both sides of the inner cavity of the temperature feedback control hot air circulating oven 1. A shelf plate 3 is slidably connected to the top of the fixed plate 2. A through groove 17 is opened on the top of the fixed plate 2. A plug rod 4 is slidably connected inside the through groove 17. An adjustment plate 6 is fixedly connected to the bottom of the plug rod 4. A return spring 5 is fixedly connected to the top of the adjustment plate 6. The top of the return spring 5 is fixedly connected to the bottom of the fixed plate 2. Two plug grooves 7 are opened at the bottom of the shelf plate 3. Specifically: The staff places the shelf plate 3 on top of the fixed plate 2, and then moves the adjusting plate 6, which in turn moves the connecting rod 4. The connecting rod 4 slides inside the through groove 17 until it moves into the connecting groove 7. The spring force of the return spring 5 pushes the adjusting plate 6 to move, which in turn moves the connecting rod 4, making the surface of the connecting rod 4 slide into the inside of the connecting groove 7 until the connecting rod 4 is fully inserted into the connecting groove 7. At this point, the position of the shelf plate 3 is fixed, which makes the shelf plate 3 more stable inside the temperature-controlled hot air circulation oven 1, avoiding left and right swaying or tilting during oven operation, and ensuring the drying effect of the items inside the oven.
[0016] Reference Figure 1 As shown in this embodiment: the surface of the plug rod 4 is slidably connected to the inside of the plug groove 7, and the outer diameter of the plug rod 4 is adapted to the inner diameter of the plug groove 7; Specifically, the sliding connection design between the plug rod 4 and the plug slot 7 not only enables the quick installation and disassembly of the shelf plate 3, but also ensures the stability of the connection. The outer diameter of the plug rod 4 and the inner diameter of the plug slot 7 are precisely matched, effectively preventing the shaking problem caused by excessive gap, and further improving the stability and reliability of the internal structure of the oven.
[0017] Reference Figure 4 As shown in this embodiment: the top of the plug rod 4 is provided with an arc-shaped surface 10; Specifically, the arc-shaped surface 10 allows the shelf plate 3 to be pushed into the temperature-controlled hot air circulation oven 1 along the top of the fixed plate 2, with the arc-shaped surface 10 contacting the bottom of the shelf plate 3. This creates a downward pushing force on the insertion rod 4, causing the insertion rod 4 to compress the return spring 5 and slide downward along the inside of the through groove 17 until the shelf plate 3 is completely pushed to the top of the fixed plate 2. At this point, the elastic force of the return spring 5 pushes the adjusting plate 6 to move the insertion rod 4 upward. At this time, the arc-shaped surface 10 of the insertion rod 4 disengages from the bottom of the shelf plate 3, and the insertion rod 4 automatically engages in the insertion groove 7 under the elastic force of the return spring 5, thus achieving a quick and stable installation of the shelf plate 3.
[0018] Reference Figure 3 and Figure 4 As shown in this embodiment: a limiting groove 8 is provided on the top of the fixed plate 2, and two limiting blocks 9 are fixedly connected to the bottom of the shelf plate 3. The surface of the limiting block 9 is slidably connected to the inside of the limiting groove 8. Specifically, the sliding connection design between the limiting block 9 and the limiting groove 8 not only further enhances the stability of the shelf plate 3 during installation, but also ensures the smooth sliding of the shelf plate 3 inside the oven.
[0019] Reference Figure 5 As shown in this embodiment: a slot 11 is provided at one end of the inner cavity of the limiting groove 8, a thrust spring 12 is fixedly connected inside the slot 11, a thrust block 13 is fixedly connected at one end of the thrust spring 12, and one end of the thrust block 13 abuts against one end of the limiting block 9. Specifically, the combined use of the thrust spring 12 and the thrust block 13 can provide a certain thrust to the limiting block 9, so that the shelf plate 3 can be tightly abutted against the fixed plate 2 after it is installed in place, thus avoiding the impact on the stability and reliability of the internal structure of the oven due to loosening.
[0020] Reference Figure 5 As shown in this embodiment: both sides of the inner cavity of the slot 11 are provided with sliding grooves 14, and both sides of the thrust block 13 are fixedly connected with sliders 15, and the surface of the sliders 15 is slidably connected to the inside of the sliding grooves 14. Specifically, the sliding connection design between the slider 15 and the groove 14 not only ensures the stability of the thrust block 13 sliding in the inner cavity of the groove 11, but also further improves the accuracy of the thrust block 13 when pushing the limit block 9.
[0021] Working principle: By placing the shelf plate 3 on top of the fixed plate 2, and then moving the adjusting plate 6, the adjusting plate 6 drives the insertion rod 4 to move. The insertion rod 4 slides inside the through groove 17 until it moves into the insertion groove 7. The return spring 5 pushes the adjusting plate 6 to move, and the adjusting plate 6 drives the insertion rod 4 to move, so that the surface of the insertion rod 4 slides into the insertion groove 7 until the insertion rod 4 is fully inserted into the insertion groove 7. At this time, the position of the shelf plate 3 is fixed, which makes the shelf plate 3 more stable inside the temperature-controlled hot air circulation oven 1, avoiding left and right swaying or tilting during oven operation, and ensuring the drying effect of the items inside the oven.
[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
