[0041] like Figure 1-7As shown, the present invention provides a tunnel oven for drying sheet metal parts, comprising a machine body 100, a furnace body 200, a heating component and a conveying component arranged on the machine body 100. During drying, the heating component provides high temperature in the furnace body 200, and the conveying component conveys the sheet metal parts 600 to be dried, and the sheet metal parts 600 are heated and dried in the process of passing through the furnace body 200.

[0042] Specifically, the conveying assembly includes a conveying roller, a conveying belt 310 and a second motor 320 .

[0043] The conveying roller is rotatably connected to the machine body 100, and a plurality of conveying rollers are provided, and the plurality of conveying rollers are arranged in sequence at intervals. The conveying belt 310 is sleeved on the conveying roller and can rotate with the rotation of the conveying roller. The second motor 320 is fixedly connected to the machine body 100, and the power output shaft of the second motor 320 is drivingly connected to the power output shaft of the conveying roller.

[0044] During drying, the second motor 320 drives the conveying roller to rotate, thereby driving the conveying belt 310 to rotate, thereby achieving the purpose of conveying the sheet metal part 600 .

[0045] The drying component includes a fan 410 and a heating element.

[0046] The fan 410 is disposed on the machine body 100, and the heating element is disposed at the air outlet of the fan 410. During drying, the heating element heats the air, and the fan 410 pressurizes the air to generate an airflow, so that the heated air enters the furnace body 200.

[0047] In this embodiment, the heating element is a heating wire.

[0048] The tunnel oven for drying sheet metal parts provided by the present invention has a simple structure and a reasonable design, and by providing a turning component, the sheet metal parts will not always keep the same side facing upward, so that the drying is more uniform and the effect is better.

[0049] like Figure 1-7 As shown, in this embodiment, a flipping assembly is also included. The flipping assembly is arranged in the furnace body 200. The flipping assembly is used to flip the sheet metal part 600 on the conveying assembly so that the tunnel furnace can heat the sheet metal part 600 evenly, thereby achieving the purpose of improving the heating effect.

[0050] like Figure 3 , 4 As shown in FIGS. 5 and 6 , the flip assembly includes a flip roller 510 , a flip plate 520 and a first motor 530 .

[0051] The flip roller 510 is disposed in the furnace body 200 and located above the conveying assembly. The flip roller 510 is rotatably connected to the furnace body 200. The flip roller 510 has magnetic force so that it can absorb the sheet metal 600 on the conveying assembly and rotate with the sheet metal 600.

[0052] The flip plate 520 is tiltedly arranged in the furnace body 200 , and the side of the flip plate 520 facing the feed end of the conveying assembly is higher. The flip plate 520 is fixedly connected to the furnace body 200 , and the higher side of the flip plate 520 abuts against the side wall of the flip roller 510 .

[0053] The first motor 530 is fixedly connected to the furnace body 200 , and the power output shaft of the first motor 530 is drivingly connected to the power input shaft of the turning roller 510 .

[0054] like Figure 7 As shown, during operation, as the conveying assembly conveys, when the sheet metal 600 passes under the flip roller 510, the A side (i.e., the side currently facing upward) of the sheet metal 600 is sucked, so that the sheet metal 600 rotates with the flip roller 510. When the sheet metal 600 rotates to the position of the flip plate 520, since the flip plate 520 conflicts with the side wall of the flip roller 510, the sheet metal 600 cannot pass through the flip plate 520, and is thus scraped off the flip roller 510 by the flip plate 520. At this time, the A side of the flip plate 520 faces the conveying side of the flip plate 520. When the sheet metal 600 slides back to the conveying side of the conveying assembly along the flip plate 520, the A side of the sheet metal 600 becomes downward, thereby achieving the purpose of flipping.

[0055] The flip assembly of this structure has a simple structure, reasonable design, and easy operation. By setting up the flip assembly, the time the sheet metal part 600 stays in the furnace body 200 is increased, thereby further improving the drying effect, and there is no need to increase the length of the furnace body 200, thus saving space.

[0056] Preferably, the distance between the lower side of the flip plate 520 and the conveying surface of the conveying assembly is greater than the overall thickness of the sheet metal 600 and less than the overall width of the sheet metal 600 to avoid flipping failure caused by the sheet metal sliding from a higher height onto the conveying assembly.

[0057] like Figure 3 , 4 As shown in FIGS. 5 and 6 , the turning roller 510 includes a roller body 511 , a rolling element and a first elastic member 514 .

[0058] The roller body 511 is rotatably connected to the furnace body 200, and the outer peripheral wall of the roller body 511 is uniformly provided with a plurality of mounting grooves. The rolling element is made of a permanent magnetic material, and the rolling element is arranged in the mounting groove. The rolling element is movably connected to the roller body 511, and the side wall of the rolling element protrudes from the side wall of the roller body 511, so that the sheet metal part 600 will not be in close contact with the side wall of the roller body 511, so that the flip plate 520 can be inserted between the roller body 511 and the sheet metal part 600, thereby achieving the purpose of facilitating the removal of the sheet metal part 600 on the flip roller 510. In this embodiment, the rolling element can be a roller 512 or a ball 513.

[0059] The two ends of the first elastic member 514 are respectively connected to the rolling element and the side wall of the mounting groove, and in a natural state, the first elastic member 514 applies elastic force to the rolling element so that the rolling element has a tendency to move in a direction away from the axis of the roller body 511. In this embodiment, the first elastic member 514 is a spring.

[0060] When in use, the sheet metal 600 adsorbed on the flip roller 510 will not tightly contact the side wall of the roller body 511 under the action of the rolling element, so that a gap is left between the sheet metal 600 and the roller body 511 for the flip plate 520 to be inserted, thereby achieving the purpose of facilitating the removal of the sheet metal 600 on the flip roller 510.

[0061] The turning roller 510 of this structure facilitates the turning plate 520 to scrape off the sheet metal part 600 thereon, thereby achieving the purpose of improving the turning effect.

[0062] like Figure 3 , 4 As shown in FIGS. 5 and 6 , an air passage is provided in the flip roller 510 , and the air passage is connected to the air pump. A blowing hole 501 is provided on the side wall of the flip roller 510 , and the blowing hole 501 is connected to the air passage.

[0063] When in use, high-pressure air is blown toward the sheet metal part 600 through the blowing holes 501 , thereby blowing away the water on the sheet metal part 600 , thereby further achieving the purpose of improving the drying effect.

[0064] In the description of the present invention, a large number of specific details are described. However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
