Description

Technical Field

[0001] This application relates to the field of oven equipment technology, and more specifically, to an oven equipment and a cathode roller surface foil treatment device. Background Technology

[0002] In existing technologies, drying ovens typically use heat sources such as heating lamps to provide the required temperature. To ensure even heat distribution, fans are usually installed to transfer heat to the materials being dried via airflow. However, while fans can transfer and diffuse heat effectively and avoid excessive energy consumption, they still have certain drawbacks. For example, when using ordinary natural fans, the heating source needs time to warm up before reaching the desired temperature, and natural air is typically cooler. Therefore, common drying ovens often fail to enter the drying state immediately upon startup, or the initial drying effect is poor.

[0003] Therefore, there is an urgent need for an oven device that can retain the advantages of energy efficiency while solving the problem of poor drying effect during the heating process. Utility Model Content

[0004] This application aims to overcome at least one of the shortcomings of the prior art and provide an oven device with a simple structure that balances oven efficiency and energy consumption.

[0005] The technical solution adopted in this application is an oven device, comprising: a unit chamber, a suction device, and a hot air duct. A first cavity is formed within the unit chamber, and a heat source is arranged on the lower side of the chamber. The suction device and the hot air duct are connected to the heat source through the first cavity. The suction device and the hot air duct switch between operating modes. When the heat source is still heating up, activating the hot air duct can quickly provide hot air at the required temperature, thereby immediately achieving the drying temperature requirement. Once the heat source reaches the expected temperature, the hot air duct is switched to the suction device, and the intake natural air can cooperate with the heat source to generate hot air at the required temperature, thus continuously carrying out subsequent oven processing in production. Furthermore, because the heating time of the heat source is short, the relatively low-energy-consumption suction device can be activated after a brief activation of the hot air duct, resulting in low overall energy consumption in airflow within the oven and avoiding significant energy consumption increases. Simultaneously, two different airflow mechanisms are provided for easy switching, quickly increasing the oven's operating temperature and balancing thermal costs and heating efficiency, significantly improving oven efficiency. Furthermore, the unit housing is equipped with two hot air pipes, and the suction device is located in the middle of the unit housing, with the hot air pipes symmetrically arranged on both sides of the suction device. Furthermore, both the hot air pipes and the suction device are located on the upper side of the unit housing.

[0006] Furthermore, the first cavity of the unit housing is also equipped with a baffle plate, which divides the first cavity into an upper cavity and a mounting cavity located below the upper cavity. The baffle plate has multiple ventilation holes, and the heat source is mounted on the mounting cavity. The suction device and the hot air duct are connected to the heat source via the upper cavity, ventilation holes, and mounting cavity. When air is guided into the first cavity by the suction device or hot air duct, the baffle plate acts as a barrier, causing the airflow to flow and spread on the baffle plate. The airflow is then discharged towards the heat source side through the ventilation holes of the baffle plate. The baffle plate facilitates both increasing the air outlet area and ensuring even distribution across all heat sources, thus improving the efficiency of the airflow in carrying heat. Furthermore, the ventilation holes on the baffle plate are evenly distributed, preferably arranged in a matrix array.

[0007] Furthermore, multiple heat sources are arranged in an arc shape along the material feeding direction. This allows for the corresponding drying process in conjunction with the arc-shaped workpiece, which can be a cathode roller. Further, the heat sources are heating tubes, and multiple heating tubes are arranged in an arc shape along the material feeding direction; that is, on the cross-section of the drying oven, multiple heating tubes form an arc-shaped structure.

[0008] Furthermore, the unit housing includes a top cover, front and rear first baffles, and left and right second baffles; the unit housing also has a partition separating the interior into an upper second cavity and a first cavity located below the second cavity; the second cavity is at least used to fill with insulation material. The insulation material includes insulation cotton. The second cavity can be filled with insulation cotton, which can reduce heat loss and lower thermal costs. Furthermore, the lower side of the second baffle has an upward-convex arc-shaped structure. Furthermore, when a spoiler is provided, both the top cover and the spoiler are arc-shaped plates.

[0009] Furthermore, it includes multiple unit boxes that are interconnected along the length direction. Furthermore, adjacent unit boxes share the same second baffle. The connection between multiple unit boxes facilitates the formation of a wide-width oven, making it compatible with large-format materials and applicable to a wide range of applications.

[0010] Furthermore, a mounting base is provided on the end side of the oven assembly, the mounting base including at least a mounting shaft; and an angle fixing base is also provided on the end side of the oven assembly, the angle fixing base cooperating with the mounting base to fix the orientation angle of the bottom surface of the oven. Through the joint positioning of the mounting base and the angle fixing base, the angle of the oven's hot surface can be fixed, thus facilitating the integration with the arc-shaped structure and deployment. The mounting shaft facilitates the rotation and adjustment of the oven's angle; furthermore, when combined with a fixing structure like the angle fixing base, the oven can be maintained at a specific angle. Furthermore, a mounting base is provided on the outermost second baffle of the overall oven, the mounting base including at least a mounting shaft; and an angle fixing base is also provided on the outermost second baffle, the angle fixing base cooperating with the mounting base to fix the orientation angle of the bottom surface of the oven.

[0011] Furthermore, the hot air duct has multiple air outlets on one side of the first cavity. These side air outlets facilitate the horizontal diffusion of hot air, allowing it to pass evenly through the heat source and generate uniformly blown hot air, thus improving drying efficiency and effect.

[0012] Furthermore, the heat source includes a heating element. In one embodiment of this application, a long strip-shaped heating lamp is used; this simplifies the structure and installation. Alternatively, the heat source can also be an entire heating panel, etc.

[0013] Furthermore, the heating element is fixed to the spoiler plate via a heating element mounting bracket. Furthermore, the heating element mounting bracket is locked onto the spoiler plate's ventilation holes. This fully utilizes the ventilation holes on the spoiler plate to provide the mounting position, reducing the additional space required for installation. Furthermore, a handle structure is also provided on the outermost second baffle of the oven device; this facilitates installation and maintenance by the operator.

[0014] Furthermore, the hot air duct is connected to a hot air blower structure.

[0015] Another objective of this application is to provide a cathode roller surface foil processing apparatus, including a cathode roller and the aforementioned drying oven apparatus opposite to the cathode roller. Further, the heating source side of the drying oven apparatus faces the cathode roller surface. The drying oven apparatus can dry the metal material generated by electrolysis on the cathode roller. Furthermore, this application can be applied to the production of composite copper foil and ultra-thin copper foil.

[0016] Compared with existing technologies, the beneficial effects of this application are as follows: The oven device of this application has a simple structure and can switch between natural wind and instant hot air, thereby overcoming the shortcomings of the heat treatment during the heating process of the heat source in existing ovens, improving the drying efficiency and initial drying effect of the oven, while avoiding a large increase in energy consumption. It rapidly increases the operating temperature of the oven and balances thermal costs and heating efficiency; significantly improving oven efficiency. When combined with a baffle structure, the incoming air can be guided to spread evenly on the baffle, expanding the area of ​​airflow action and thus covering the area of ​​the heat source, improving the area and efficiency of hot air action. Furthermore, when a partition is used to form a second cavity, the baffle and the partition form the upper cavity of the first cavity. The suction device and hot air pipe are connected to the upper cavity. The second cavity is filled with insulation cotton to ensure the temperature of the flowing air entering the first cavity and conducting heat with the heat source; while providing hot air, it also reduces heat loss. The overall oven structure is simple, the drying efficiency is high, and the drying effect, energy consumption, and cost are also guaranteed. It is suitable for workpieces with cylindrical / arc surfaces, such as cathode rollers, and works in conjunction with them to achieve good heat drying results. Attached Figure Description

Detailed Implementation

[0025] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this application. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this application, not all embodiments, and are only used to illustrate this application, and should not be regarded as limiting the scope of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Example 1

[0028] like Figures 1-2 As shown, this embodiment discloses an oven device 1000, including: a unit box 1100, a suction device 1300, and a hot air pipe 1200. A first cavity 1160 is formed inside the unit box 1100. A heat source 1164 is arranged on the lower side of the box. The suction device 1300 and the hot air pipe 1200 are connected to the heat source 1164 through the first cavity 1160. Specifically, the hot air pipe 1200 and the suction device 1300 are both disposed on the upper side of the unit box 1100. The hot air pipe 1200 is connected to a hot air blower structure. Two hot air pipes 1200 are disposed on the unit box 1100. The suction device 1300 is disposed in the middle of the unit box, and the hot air pipes 1200 are symmetrically disposed on both sides of the suction device 1300. In order to improve the horizontal diffusion of the introduced air and ensure the effective area, the hot air pipe 1200 in this embodiment is provided with multiple air outlet holes on the pipe wall on one side of the first cavity 1160.

[0029] In this embodiment, multiple heat sources 1164 are arranged on the lower side of the chamber. Each heat source 1164 is a heating tube, and these heating tubes are arranged in an arc shape along the material feeding direction; that is, on the cross-section of the oven, the multiple heating tubes form an arc-shaped structure. Specifically, this embodiment uses long, strip-shaped heating lamps, which simplifies the structure and installation. Alternatively, the heat source 1164 can also be an entire heating panel, etc.

[0030] The unit housing 1100 includes an upper cover plate 1110, front and rear first baffles 1120, and left and right second baffles 1130. The unit housing 1100 also has a partition 1150, which separates the interior of the housing into an upper second cavity 1140 and a first cavity 1160 located below the second cavity 1140. The second cavity 1140 is at least filled with insulation material, including insulation cotton. This reduces heat loss of stagnant hot air when the inlet air volume is large and the inlet air conducts heat with the heat source 1164. Furthermore, to accommodate the aforementioned arc-shaped arrangement of the heating tubes, the lower side of the second baffle 1130 has an upward-convex arc-shaped structure. Partial lower cover plates 1165 may also be provided at both ends of the oven device 1000, such as... Figure 7 As shown, this facilitates the formation of a stable hot-drying zone.

[0031] like Figures 2-6 As shown, in order to improve the effect of the introduced air, a baffle 1162 is also provided in the first cavity 1160 of the unit housing 1100. The baffle 1162 divides the first cavity 1160 into an upper cavity 1161 and a mounting cavity 1163 located below the upper cavity 1161. The mounting cavity 1163 is a downward-opening cavity. The baffle 1162 is provided with a plurality of ventilation holes 1162A. The heat source 1164 is installed on the mounting cavity 1163. The air suction device 1300 and the hot air pipe 1200 are connected to the heat source 1164 in the mounting cavity 1163 through the upper cavity 1161 and the ventilation holes 1162A. When the air intake device 1300 or the hot air duct 1200 guides air into the first cavity 1160, the baffle 1162 forms a barrier, causing the introduced air to flow and spread on the baffle 1162. The introduced air is then discharged towards the heat source side through the ventilation holes 1162A of the baffle 1162. The ventilation holes on the baffle 1162 are evenly distributed, and in this embodiment, they are evenly arranged in a matrix array. In addition, when the baffle 1162 is provided, both the upper cover plate 1110 and the baffle 1162 are arc-shaped plates.

[0032] The heating element can be fixed to the spoiler 1162 by the heating element mounting bracket; and locked to the ventilation hole 1162A of the spoiler 1162 by the heating element mounting bracket.

[0033] In this embodiment, a handle structure 1133 is also provided on the outermost second baffle 1130 of the oven device 1000; this facilitates the installation and maintenance by the operator.

[0034] like Figures 1-2 As shown, the oven device 1000 in this embodiment can be composed of multiple unit boxes 1100; for example, it includes multiple unit boxes 1100 that are connected to each other in the length direction. Adjacent unit boxes 1100 share the same second baffle 1130. By connecting multiple unit boxes 1100, a wide oven is formed, which is compatible with large-size materials.

[0035] To accommodate the hot drying of curved workpieces, the oven device 1000 may require installation at a specific angle. Therefore, in this embodiment, the oven device 1000 has a mounting base 1131 at one end, which includes at least a mounting shaft 1131A; and an angle fixing base 1132 at the other end, which cooperates with the mounting base 1131 to fix the angle of the oven's bottom surface. Through the joint positioning of the mounting base 1131 and the angle fixing base 1132, the angle of the oven's hot drying surface is fixed, aligning with the curved structure and deployment. Specifically, the second outermost baffle 1130 of the overall oven has a mounting base 1131, which includes at least a mounting shaft 1131A; and the second outermost baffle 1130 also has an angle fixing base 1132, which cooperates with the mounting base 1131 to fix the angle of the oven's bottom surface.

[0036] An example implementation principle: The suction device 1300 and the hot air duct 1200 switch operation. When the heat source 1164 is still heating up, activating the hot air duct 1200 can quickly provide hot air at the required temperature, thus immediately achieving the drying temperature requirement. Once the heat source 1164 has reached the expected temperature, the hot air duct 1200 is switched to the suction device 1300. The intake air can then work with the heat source 1164 to generate hot air at the required temperature, thus continuing the subsequent oven processing. Furthermore, because the heat source 1164 heats up in a short time, the low-energy suction device 1300 can be activated after a brief activation of the hot air duct 1200. Overall, the oven consumes less energy in terms of airflow, avoiding a significant increase in energy consumption. Simultaneously setting up two different airflow mechanisms facilitates immediate switching, quickly increasing the oven's operating temperature and balancing thermal costs and heating efficiency, significantly improving oven efficiency.

The heating source 1164 of the drying oven device 1000 faces the cathode roller surface. The drying oven device 1000 can dry the metal material generated by electrolysis on the cathode roller. In specific applications of product manufacturing, this application can be applied to the production of composite copper foil, composite current collectors, ultra-thin copper foil, etc.
