Description

Technical Field

[0001] This utility model relates to the technical field of copper foil production equipment, and more specifically, to a shockproof drying oven. Background Technology

[0002] In the copper foil production process, after the copper foil stripped from the cathode roller is immersed in an anti-oxidation tank, excessive anti-oxidation solution residue easily adheres to its surface. If such residue is not effectively removed, it will not only cause oxidation on the copper foil surface, leading to quality deterioration, but will also form interface contamination in subsequent surface treatment processes, directly affecting key indicators such as the copper foil's conductivity and peel strength.

[0003] The closest existing drying oven to this application is authorized by publication number CN212409335U, which describes an energy-saving device for a double-sided air-floating drying oven hot air circulation system. This device includes an upper drying oven return air duct, a lower drying oven return air duct, and an exhaust pipe. The upper drying oven return air duct connects to the exhaust pipe via an upper air outlet and an upper ventilation pipe; the lower drying oven return air duct connects to the exhaust pipe via a lower air outlet and a lower ventilation pipe. An isolation baffle is provided between the exhaust pipe and the connections to the upper and lower ventilation pipes.

[0004] The drying oven described above can only achieve air circulation, and it still cannot guarantee the stability of the material conveying process when drying materials. However, uneven conveying will cause uneven heating, resulting in warping and reducing the yield of processed products.

[0005] In view of this, the present invention provides an effective shockproof drying oven that avoids warping. Utility Model Content

[0006] The purpose of this invention is to provide an effective shockproof drying oven that prevents warping.

[0007] A shockproof drying oven, characterized in that it comprises:

[0008] The upper drying box 1 and the lower drying box 2 are arranged opposite each other and form a feeding channel 3 in the middle for conveying copper foil;

[0009] A conveying mechanism for feeding copper foil from one end to the other end, wherein the copper foil passes through the feeding channel 3 in sequence during the conveying process;

[0010] The lifting structure installed in the upper drying box 1 and / or lower drying box 2 can support or suspend the copper foil from top to bottom and / or from bottom to top when the copper foil is located in the feeding channel 3, preventing the copper foil from sagging, shaking or deforming during the drying process. The lifting structure generates an upward lifting force, which directly counteracts the weight of the copper foil and prevents sagging. The stable airflow generated by the lifting structure can absorb the small vibrations in the copper foil conveying process, reduce the shaking amplitude, and at the same time, the uniform hot air distribution reduces thermal stress deformation.

[0011] The upper drying box 1 and the lower drying box 2 are respectively provided with an air inlet and an air return end, which are used to form a hot air circulation field from top to bottom and / or from bottom to top to dry the upper and lower surfaces of the copper foil simultaneously.

[0012] In some embodiments, the lifting structures in the upper drying chamber 1 and / or lower drying chamber 2 are symmetrically distributed vertically, thereby forming a lifting airflow with combined vertical force inside the upper constant temperature drying chamber 31 and the lower constant temperature drying chamber 32, so that the copper foil is subjected to balanced force in the vertical direction, suppressing local warping caused by unilateral airflow fluctuations or uneven temperature, ensuring the stability of the material conveying process and avoiding warping.

[0013] In some embodiments, the lifting structure in the upper drying chamber 1 and / or lower drying chamber 2 includes two lifting units 4. The two lifting units 4 in the upper drying chamber 1 and / or lower drying chamber 2 are symmetrically arranged. The center lines of the two lifting units 4 in the upper drying chamber 1 and the two lifting units 4 in the lower drying chamber 2 are extended to form a parallelogram, which makes the upper constant temperature drying chamber 31 and the lower constant temperature drying chamber 32 form a more stable lifting airflow with upper and lower combined force, further ensuring the stability of the material conveying process and avoiding warping. The upper and lower lifting units are symmetrically distributed in a parallelogram to ensure that the airflow forms a uniformly covered support surface on the copper foil travel path, avoiding local support force differences. The airflow in the diagonal direction (copper foil travel direction) of the parallelogram is more concentrated, reducing lateral turbulence, enhancing longitudinal stability, and preventing the copper foil from S-shaped twisting due to uneven tension.

[0014] Furthermore, the lifting unit 4 is an airflow lifting device, including a porous guide plate 41 or a nozzle array arranged in the upper drying box 1 and / or the lower drying box 2; when hot air is sprayed onto the copper foil through the guide plate 41 or the nozzle array at a set angle and flow rate, an air cushion or opposing airflow is formed between the copper foil and the upper and lower drying boxes 2, thereby providing an upward or downward lifting force without contacting the copper foil.

[0015] Furthermore, the nozzle array is arranged in multiple rows, with a spacing of 20mm-50mm between adjacent nozzles and a nozzle outlet diameter of 2mm-5mm. Too dense a nozzle array increases energy consumption, while too sparse a nozzle array results in uneven support.

[0016] Furthermore, each nozzle can be tilted 0°-30° relative to the copper foil surface to form an adjustable airflow during copper foil transport. By adjusting the nozzle angle and airflow, a stable airflow support layer can be established on the upper or lower surface of the copper foil to avoid large-area sagging or local warping. Within the 0°-30° range, the tilted airflow generates a component force consistent with the direction of copper foil movement, assisting transport and reducing frictional resistance, thus preventing edge curling caused by pure vertical airflow. At the same time, the small-angle tilt fluidizes the airflow, reducing local pressure fluctuations caused by eddies and preventing large-area sagging or point warping.

[0017] In some embodiments, a return air chamber 5 is provided inside the upper drying box 1 and the lower drying box 2. The pressure of the return air chamber 5 is lower than that of the external environment, so that the external cold air can enter the return air chamber 5 from the inlet or outlet of the feeding channel 3 and mix with the high-temperature return air. Through this negative pressure return air mode, the return air can be pre-cooled and the upper and lower air fields can be further balanced without increasing the additional fan energy consumption.

[0018] In some embodiments, the upper drying chamber 1 and the lower drying chamber 2 are also connected to a return air circulation device 6. The return air circulation device 6 includes a first transfer device 61, a condenser 62, a heating unit control device 63, an energy storage device 64, and a second transfer device 65 connected sequentially along the return air path. The return air output from the upper drying chamber module 1 and the lower drying chamber module 2 enters the condenser 62 through the first transfer device 61 for dehumidification, is then heated by the heating unit control device 63 and enters the energy storage device 64, and is finally transported back to the air inlet of the upper drying chamber 1 and the lower drying chamber 2 by the second transfer device 65, forming a return air circulation.

[0019] The beneficial effects of this utility model are as follows: This utility model proposes a shockproof drying box. Through a support structure arranged within the upper drying box 1 and / or lower drying box 2, when the copper foil is located within the feeding channel 3, the support structure can support or suspend the copper foil from top to bottom and / or from bottom to top, preventing the copper foil from sagging, shaking, or deforming during the drying process. The two support units 4 in the upper drying box 1 and the two support units 4 in the lower drying box 2 extend their centerlines to form a parallelogram, creating a more stable combined upward and downward lifting airflow within the upper constant temperature drying chamber 31 and the lower constant temperature drying chamber 32, further ensuring the stability of the material conveying process and preventing warping. The upper drying box 1 and lower drying box 2 also have a return air chamber 5 inside. The pressure in the return air chamber 5 is lower than the external ambient pressure, allowing external cold air to enter the return air chamber 5 from the inlet or outlet of the feeding channel 3 and mix with the high-temperature return air. This reduces the load on the condenser box and balances the temperature to prevent overheating or excessively rapid cooling on one side. Attached Figure Description
