For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] As Figures 1 to 4 shown, the drying oven for the composite current collector of the present utility model includes: an oven body 1 and a containing box body 2. The containing box body 2 is independently arranged inside the oven body 1. An air flow channel 3 is formed between the inner wall of the oven body 1 and the outer wall of the containing box body 2. An air inlet 21 is formed at the bottom of the containing box body 2, and an air outlet 22 is formed at the top. The oven body 1 has a feed inlet 11 and a discharge outlet 12; a circulation motor 4 and a heating device 5. The circulation motor 4 is arranged at the bottom of the oven body 1 and is directly opposite to the air outlet 22 of the containing box body 2. A circulation fan is arranged at the rotating shaft end of the circulation motor 4. The heating device 5 is arranged inside the air flow channel 3; a roller assembly 6 is arranged inside the containing box body 2. Among them, the composite current collector passes through the roller assembly 6 to extend the length of the composite current collector inside the containing box body 2.

[0030] See Figure 1 、 Figure 2 , an air flow channel 3 is formed between the top, bottom, and both side portions of the containing box body 2 and the oven body 1. Among them, the heating device 5 is arranged on both side portions of the containing box body 2. At least one air outlet 22 is formed at the top of the containing box body 2. The bottom of the containing box body 2 is an opening, and this opening is the air inlet 21. Among them, the circulation motor 4 is directly opposite to the air outlet 22.

[0031] See Figure 2 , both the feed inlet 11 and the discharge outlet 12 of the oven body 1 are communicated with the inside of the containing box body 2. One end of the composite current collector enters the containing box body 2 through the feed inlet 11, and the composite current collector winds around the roller assembly 6 inside the containing box body 2 and extends out of the oven body 1 through the discharge outlet 12.

[0032] When drying and dehumidifying the composite current collector, first, the composite current collector enters the containing box body 2 through the feed inlet 11 and extends out through the discharge outlet 12. The composite current collector winds around the roller assembly 6 inside the containing box body 2. Thereafter, the heating device 5 is controlled to operate. At the same time, the circulation fan is controlled to operate by using the circulation motor 4 to extract the air flow inside the containing box body 2 into the air flow channel 3. The air flow flowing through the air flow channel 3 is heated by the heating device 5 and then enters the containing box body 2 through the air inlet 21 at the bottom of the containing box body 2, so as to perform a drying operation on the composite current collector winding around the roller assembly 6; through this kind of arrangement, the hot air can be recycled to heat the composite current collector, reducing the re-heating loss of the air flow and reducing the production cost.

[0033] In one or more embodiments, the roller assembly 6 at least includes a first roller 61, a second roller 62, and a third roller 63 that are sequentially arranged along the conveying direction of the composite current collector. Among them, the first roller 61 and the third roller 63 are parallel and higher than the second roller 62, or the first roller 61 and the second roller 62 are parallel and lower than the second roller 62.

[0034] See Figure 2 , after the composite current collector enters the accommodating box body 2 through the feed port 11, it sequentially winds around the first roller 61, the second roller 62, and the third roller 63. Through this setting, the extension length of the composite current collector in the accommodating box body 2 can be increased, which is convenient for the hot air flow to heat the composite current collector.

[0035] In other possible embodiments, a fourth roller, a fifth roller, etc. can also be configured; the positions of the fourth roller and the fifth roller are not limited and can be selected according to actual production needs.

[0036] In one or more embodiments, a flow equalizing plate 7 is arranged at the air inlet 21 at the bottom of the accommodating box body 2 so that the hot air flow can uniformly flow into the accommodating box body 2. See Figure 1 , Figure 2 , the flow equalizing plate 7 is a porous plate, and the material of the flow equalizing plate 7 can be copper, aluminum, iron, or steel. By configuring the flow equalizing plate 7, the hot air flow in the air flow channel 3 can uniformly flow into the accommodating box body 2, ensuring the uniformity of drying each part of the composite current collector.

[0037] In one or more embodiments, a tensioning assembly 8 is arranged at the front position and / or the rear position of the roller assembly 6 in the accommodating box body 2. Among them, the composite current collector passes through the tensioning assembly 8. The tensioning assembly 8 can change its position to tension the composite current collector when the heating device 5 is working and reset to relax the composite current collector when the heating device 5 is not working; the tensioning assembly 8 includes: a turntable 81, the turntable 81 is rotatably arranged on the side of the accommodating box body 2, the turntable 81 has a first rotating part 811 and a second rotating part 812 connected by a central axis, the first rotating part 811 is located inside the accommodating box body 2, and the second rotating part 812 is located outside the accommodating box body 2; a first tensioning roller 813 and a second tensioning roller 814, the first tensioning roller 813 and the second tensioning roller 814 are rotatably arranged on the first rotating part 811 of the turntable 81, and the composite current collector winds around the first tensioning roller 813 and the second tensioning roller 814; a deformation member 815, the deformation member 815 has opposite first and second ends, the first end is arranged on the inner wall of the oven body 1, the second end is arranged on the second rotating part 812 of the turntable 81, and the deformation member 815 is made of shape memory metal; the deformation member 815 is a coil spring.

[0038] See Figure 2 , Figure 3 , Figure 4, in the initial state, the heating device 5 is not working, the deformation member 815 is not deformed, and the first tension roller 813 and the second tension roller 814 on the turntable 81 are in a "one" shape; when the heating device 5 starts to work, the heating device 5 can heat the deformation member 815, and the deformation member 815 made of shape memory metal deforms, thereby driving the turntable 81 to rotate counterclockwise, so that the first tension roller 813 and the second tension roller 814 are in a "|" shape, realizing the tensioning of the composite current collector wound around the first tension roller 813 and the second tension roller 814, avoiding the problem that the composite current collector is blown by the hot air flow and swings, and improving the drying effect of the composite current collector in this application.

[0039] In one or more embodiments, the heating device 5 is one of a heating tube or a heating wire.

[0040] In one or more embodiments, the material of the accommodating box body 2 is one or more of copper, silver, aluminum, and iron. It should be noted that copper, silver, aluminum, and iron have certain heat conduction properties, which can ensure the stability of the temperature inside the accommodating box body 2 and further improve the heating and drying efficiency of the composite current collector.

[0041] In one or more embodiments, a shield 9 extending to the circulation motor 4 is arranged at the air outlet 22 of the accommodating box body 2. See Figure 1 , Figure 2 , through this setting, it can ensure the air flow pumping of the circulation fan in the accommodating box body 2 and accelerate the air flow efficiency in the accommodating box body 2 and the air flow channel 3.

[0042] The above embodiments are only for explaining the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention.
