Technical Field

[0001] The utility model relates to the technical field of heat - collecting film processing, in particular to a hot - air circulation oven. Background Art

[0002] During the processing of the heat - collecting film, it is necessary to use an oven to dry the polymer films on both sides of the heat - collecting film. At present, when the oven is in use, multiple electric heating tubes inside the oven are used to complete the drying operation. However, in actual use, each electric heating tube heats the air in the oven from the inside out with itself as the center. At the same time, there is also a problem that the air between two adjacent electric heating tubes is heated unevenly. Coupled with the fact that the air in the oven has no other driving force except being driven by the movement of the heat - collecting film, the air flow in the oven is poor, which further leads to uneven heating of the air in the oven. This also causes uneven drying during the process of the heat - collecting film being dried in the oven, affecting the drying effect of the heat - collecting film. Therefore, a hot - air circulation oven is needed to meet the requirements. Content of the Utility Model

Each moving plate is fixed with multiple connecting rods, and each connecting rod slides through the box body. A connecting plate is commonly fixed on multiple connecting rods outside the box body, and a linear motor is fixed on the connecting plate, and the linear motor is fixed on the box body.

[0006] Preferably, multiple holes are provided through the moving plate.

[0007] Preferably, an inspection port is provided through the box body, and a shielding cover is provided on the inspection port. The shielding cover is snap - fitted on the box body, and multiple locking mechanisms are provided between the box body and the shielding cover.

[0008] Preferably, a toolbox is fixed on the shielding cover, and the toolbox is arranged outside the box body.

[0009] Preferably, the locking mechanism includes a fixed block and a rotating shaft. The fixed block and the rotating shaft are respectively fixed on the shielding cover and the box body, and a limiting rod is rotatably arranged on the rotating shaft.

[0010] Preferably, the fixing block is in an arc structure, the limiting rod is in an inverted L-shaped structure, and the fixing block and the rotating shaft are coaxially arranged.

[0011] The hot air circulation oven proposed by the present utility model has the beneficial effects that: when in use, with the assistance of the linear motor, the two moving plates reciprocate up and down in the box body, and the reciprocating up and down movement of the two moving plates is used to drive the air flow in the box body, making the air in the box body circulate, causing the air around the multiple electric heating tubes to constantly change, so that the multiple electric heating tubes can uniformly heat the air in the box body, and further making the heat collection film more evenly heated when being dried in the box body, ensuring the drying effect of the heat collection film in the box body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Embodiment 1: Refer to Figures 1 - 3, a hot air circulation oven, comprising a box body 1, on which there are two through ports 2 and a plurality of electric heating tubes 3. When the heat collecting film passes through the two through ports 2 and passes through the box body 1, the plurality of electric heating tubes 3 are evenly distributed on both sides of the heat collecting film. Inside the box body 1, two moving plates 4 are symmetrically arranged, and the plurality of electric heating tubes 3 are arranged between the two moving plates 4. A plurality of holes 5 are provided through the moving plates 4. Through the arrangement of the plurality of holes 5, when driving the moving plates 4 to reciprocate, a plurality of circulating eddies are formed around the moving plates 4 and on both sides of the plurality of holes 5, so as to stir the air in the box body 1 and make the plurality of electric heating tubes 3 heat the air in the box body 1 more evenly;

[0019] A plurality of connecting rods 6 are fixed on each moving plate 4, and each connecting rod 6 slidably penetrates through the box body 1. A connecting plate 7 is commonly fixed on the plurality of connecting rods 6 outside the box body 1. A linear motor 8 is fixed on the connecting plate 7, and the linear motor 8 is fixed on the box body 1. The linear motor 8 drives the connecting plate 7 to reciprocate up and down, and the connecting plate 7 drives the two moving plates 4 to move in the box body 1 through the plurality of connecting rods 6.

[0020] During use, start the linear motor 8. The linear motor 8 drives the two moving plates 4 to reciprocate up and down in the box body 1 through the connecting plate 7 and the plurality of connecting rods 6. Coupled with the arrangement of the plurality of holes 5, the reciprocating movement of the two moving plates 4 is used to drive the flow of air in the box body 1, so that the air in the box body 1 circulates, and the air around the plurality of electric heating tubes 3 keeps changing. Thus, the plurality of electric heating tubes 3 can evenly heat the air in the box body 1, and further make the heat collecting film heat more evenly when being dried in the box body 1, ensuring the drying effect of the heat collecting film in the box body 1.

[0021] Embodiment 2: In Embodiment 1, during the use of the plurality of electric heating tubes 3, in order to ensure the use effect of the plurality of electric heating tubes 3, the plurality of electric heating tubes 3 are regularly overhauled. Although there are two through ports 2 on the box body 1, they are only suitable for the passing of the heat collecting film and not for the overhaul of the plurality of electric heating tubes 3. Refer to Figures 2 - 4 , as another preferred embodiment of the present invention, different from Embodiment 1, a plurality of support legs 14 are fixed on the box body 1, and an overhaul port is provided through the box body 1. A shielding cover 9 is provided on the overhaul port, and the shielding cover 9 is clamped on the box body 1. When drying the heat collecting film in the box body 1, the shielding cover 9 is used to block the overhaul port to reduce the loss of heat of the heated air in the box body 1. A plurality of locking mechanisms are commonly provided between the box body 1 and the shielding cover 9, and the shielding cover 9 is detachably installed on the box body 1 by means of the plurality of locking mechanisms.

[0022] A tool box 13 is fixed on the shielding cover 9, and the tool box 13 is arranged outside the box body 1. The tool box 13 is convenient for placing maintenance tools. The locking mechanism includes a fixed block 10 and a rotating shaft 11. The fixed block 10 and the rotating shaft 11 are respectively fixed on the shielding cover 9 and the box body 1. The fixed block 10 is an arc-shaped structure. The fixed block 10 and the rotating shaft 11 are coaxially arranged. A limiting rod 12 is rotatably provided on the rotating shaft 11. The limiting rod 12 is an inverted L-shaped structure. When the limiting rod 12 of the inverted L-shaped structure rotates with the rotating shaft 11 as the axis, it can be engaged with the fixed block 10. The fixed block 10 blocks the limiting rod 12, so that the shielding cover 9 is limited to the box body 1.

[0023] When the solar collecting film is dried in the box body 1, multiple locking mechanisms are used to limit the shielding cover 9 on the box body 1 and cover the inspection port to ensure the effect of drying the solar collecting film. When the inside of the box body 1 needs to be inspected, multiple limit rods 12 are moved to allow the multiple limit rods 12 to rotate around the multiple rotating shafts 11 respectively until the multiple limit rods 12 are separated from the multiple fixed blocks 10 respectively. At this time, pulling the shielding cover 9 can not only allow the shielding cover 9 to be separated from the box body 1, but also expose the inspection port, which is convenient for the staff to inspect the inside of the box body 1.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
