Description

Technical Field

[0001] This utility model relates to the field of flexible substrate curing technology, and in particular to curing apparatus. Background Technology

[0002] Currently, infrared heating combined with a CV conveyor platform is commonly used to achieve continuous curing of flexible substrates. However, the longer the curing time of the flexible substrate, the longer the required CV conveyor platform becomes, resulting in a larger overall size and footprint of the equipment, and higher production costs. A CV conveyor line is an automated production line that can transport flexible substrates from one workstation to another, achieving automation and efficiency in the flexible substrate production line. Curing of flexible substrates specifically refers to heating the flexible substrate to cure the coating applied to it; and continuous curing specifically refers to heating the flexible substrate for a preset time without stopping the machine, even while the flexible substrate is constantly moving.

[0003] To address the above issues, a solid baking device is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a solid-heating device that is small in size, occupies less space, and has a lower cost, while ensuring continuous solid-heating of flexible substrates within a preset heating time.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A curing apparatus for curing a coating on a flexible substrate, comprising:

[0007] First cavity;

[0008] A heating element is disposed in the first cavity, and the heating element is used to heat the interior of the first cavity;

[0009] A plurality of conveying rollers are used to convey the flexible substrate. The plurality of conveying rollers are arranged in a vortex structure and rotated in the first cavity. The flexible substrate is conveyed back and forth along each of the conveying rollers. The number of turns of the flexible substrate in the vortex structure on the conveying rollers is matched with the moving speed of the flexible substrate and the preset heating time of the flexible substrate.

[0010] Further, the conveying roller includes:

[0011] The first conveying roller is rotatably disposed within the first cavity;

[0012] The second conveying roller is rotatably disposed within the first cavity. The first conveying roller and the second conveying roller are parallel and opposite to each other, and the flexible substrate is sandwiched between the first conveying roller and the second conveying roller.

[0013] Furthermore, the solid baking device also includes:

[0014] The edge guards are respectively provided at the opposite ends of the first conveying roller and the opposite ends of the second conveying roller, and the edge guards on two adjacent first conveying rollers are connected to each other, and the edge guards on two adjacent second conveying rollers are connected to each other.

[0015] Furthermore, the first conveying roller is a long roller, and the second conveying roller consists of two short rollers. The surface of the flexible substrate that is not coated with the coating abuts against the long roller, and the other surface of the flexible substrate abuts against the short rollers. The two short rollers are located on opposite sides of the coating, so that the short rollers do not contact the coating.

[0016] Furthermore, the solid baking device also includes:

[0017] A take-up roller is located within the first cavity. The take-up roller is arranged parallel to the conveying roller and is rotatably configured to take up the flexible substrate.

[0018] Furthermore, the solid baking device also includes:

[0019] The second cavity is located inside the first cavity, and the heat in the first cavity will not enter the second cavity. The second cavity is used to cool the flexible substrate after it has been heated by the first cavity. The take-up roller is rotatably disposed in the second cavity.

[0020] Furthermore, the outer peripheral surface of the second cavity is covered with a heat insulation component.

[0021] Furthermore, the solid baking device also includes:

[0022] A cooling element is disposed in the second cavity and is used to cool the interior of the second cavity.

[0023] Furthermore, the heating element includes:

[0024] A heating element is disposed in the first cavity;

[0025] A first fan is disposed in the first cavity. The first fan is used to disperse the heat generated by the heating body so that the heat inside the first cavity is evenly distributed.

[0026] Furthermore, the solid baking device also includes:

[0027] The third cavity is located at the inlet end of the first cavity, and the third cavity is used to preheat the flexible substrate.

[0028] The beneficial effects of this utility model are as follows:

[0029] The interior of the first cavity is heated by a heating element, and several conveying rollers arranged in a vortex structure are rotated within the first cavity. These rollers clamp and convey the flexible substrate, allowing it to be arranged in a vortex structure within the first cavity. This extends the substrate's path within the first cavity, thereby prolonging the heating time. This ensures that the flexible substrate is heated for the preset time even with continuous movement, resulting in better coating curing. This allows for continuous curing without downtime, leading to higher production efficiency. Furthermore, this method eliminates the need for a long CV conveyor platform, resulting in a smaller overall curing device size, less space required, and lower cost. Moreover, the number of vortex turns of the flexible substrate on the conveying rollers can be adjusted according to the required preset heating time and the actual movement speed of the substrate, thus regulating its path within the first cavity and ensuring the substrate reaches the preset heating time. This makes the device suitable for curing flexible substrates with different preset heating times, resulting in good applicability and versatility. Attached Figure Description

[0042] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0043] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] Currently, infrared heating combined with a CV conveyor platform is commonly used to achieve continuous curing of flexible substrates. However, the longer the curing time of the flexible substrate, the longer the CV conveyor platform needs to be, resulting in a larger size and footprint of the entire device and higher production costs.

[0045] Therefore, this embodiment proposes a curing device for heating a flexible substrate to solidify the coating on it, thereby achieving continuous curing of the flexible substrate. The entire curing device is small in size, occupies little space, and has low cost. Specifically, the continuous curing operation refers to heating the flexible substrate while it remains in motion for a preset heating time, allowing the coating to solidify. The specific material of the flexible substrate is not limited; any flexible substrate will suffice. The specific type of coating needs to be determined based on the material of the flexible substrate and the coating requirements.

[0046] Specifically, such as Figures 1 to 3As shown, the baking device includes a first cavity 1, a heating element 14, and several conveying rollers 12. The heating element 14 is disposed in the first cavity 1 to heat the interior of the first cavity 1, thereby heating the flexible substrate 10 within the first cavity 1. The flexible substrate 10 is sandwiched within the conveying rollers 12, allowing it to be repeatedly conveyed back and forth along each conveying roller 12. The several conveying rollers 12 are arranged in a vortex structure within the first cavity 1. The flexible substrate 10 is sequentially sandwiched on each conveying roller 12, so that the flexible substrate 10 within the first cavity 1 is arranged in a vortex structure. The number of turns of the flexible substrate 10 in the vortex structure on the conveying rollers 12 matches the moving speed of the flexible substrate 10 and the preset heating time of the flexible substrate 10. Specifically, the winding direction of the flexible substrate 10 within the first cavity 1 is as follows: Figure 3 As shown by arrow A in the diagram.

[0047] Compared to existing technologies, the curing apparatus in this embodiment changes the arrangement of the flexible substrate 10 within the first cavity 1. By rotating several conveyor rollers 12 arranged in a vortex structure within the first cavity 1, the conveyor rollers 12 clamp and convey the flexible substrate 10, allowing the flexible substrate 10 to be arranged in a vortex structure within the first cavity 1. This extends the placement path of the flexible substrate 10 within the first cavity 1, thereby extending the heating time of the flexible substrate 10 within the first cavity 1. This ensures that the flexible substrate 10 is heated for the preset heating time even when it is moving continuously, resulting in better curing of the coating on the flexible substrate 10. This enables continuous curing operation of the flexible substrate 10 without the need for machine downtime, resulting in higher production efficiency. Using this method, since a long CV conveyor platform is not required, the overall curing apparatus is smaller, occupies less space, and has lower costs. The preset heating time of the flexible substrate 10 needs to be determined according to the curing requirements of the coating on the flexible substrate 10, and is not specifically limited here.

[0048] Furthermore, by adjusting the number of turns of the flexible substrate 10 in a vortex structure on the conveying roller 12 according to the preset heating time required by the flexible substrate 10 and the actual moving speed of the flexible substrate 10, the length of the path set in the first cavity 1 of the flexible substrate 10 can be adjusted, so that the flexible substrate 10 can reach the preset heating time in the first cavity 1, thereby being applicable to the curing requirements of flexible substrates 10 with different preset heating times, making the applicability and versatility of the entire curing device good.

[0049] Furthermore, such as Figure 3 and Figure 4As shown, the conveying roller assembly 12 includes a first conveying roller 121 and a second conveying roller 122. The first and second conveying rollers 121 and 122 are rotatably disposed within the first cavity 1, parallel and opposite to each other. The flexible substrate 10 is sandwiched between the first and second conveying rollers 121 and 122, thereby enabling the flexible substrate 10 to move through rotation, achieving directional conveying of the flexible substrate 10. Both the first and second conveying rollers 121 and 122 can be driven by a motor, gears, and belt drive structure, thus achieving their rotation.

[0050] Specifically, such as Figures 4 to 6 As shown, the first conveying roller 121 is a long roller, and the second conveying roller 122 consists of two short rollers. The uncoated surface of the flexible substrate 10 presses against the long roller, while the coated surface of the flexible substrate 10 presses against the short rollers. The two short rollers are located on both sides of the coating, so that the short rollers do not come into contact with the coating when pressing against the flexible substrate 10, thereby better protecting the coating on the flexible substrate 10.

[0051] The specific lengths of the long and short rollers are not limited, as long as the long rollers can support the flexible substrate 10 and the short rollers can abut against the flexible substrate 10 without contacting the coating. The materials of both the long and short rollers must meet the requirements of high temperature resistance and chemical corrosion resistance. The shapes of the long and short rollers can be circular or gear-shaped, which are not limited here, as long as they can achieve the conveying of the flexible substrate 10.

[0052] Furthermore, such as Figure 3 and Figure 5 As shown, the baking device also includes edge guards 13. Edge guards 13 are respectively provided at the opposite ends of the first conveying roller 121 and at the opposite ends of the second conveying roller 122. That is, edge guards 13 are respectively provided at the opposite ends of the long rollers, edge guards 13 are provided at the outer end of one of the short rollers, and edge guards 13 are provided at the outer end of the other short roller. The edge guards 13 on two adjacent first conveying rollers 121 are connected to each other so that the edge guards 13 on each first conveying roller 121 form an integral connection structure. The edge guards 13 on two adjacent second conveying rollers 122 are connected to each other so that the edge guards 13 on each second conveying roller 122 form an integral connection structure.

[0053] By setting the edge guard 13, the flexible substrate 10 can always be located between the edge guards 13 at opposite ends on the conveying roller 12. The edge guard 13 provides a limiting effect on the flexible substrate 10, so as to guide the flexible substrate 10 to be conveyed in the conveying direction of the conveying roller 12. This ensures that the flexible substrate 10 can move directionally from the previous conveying roller 12 to the next conveying roller 12, avoiding the problem of the flexible substrate 10 deviating during the movement, and better ensuring the directional conveying of the flexible substrate 10.

[0054] Specifically, the edge guard 13 can be a structure formed in one piece within the first cavity 1, or it can be a separate accessory structure installed on the opposite ends of the first conveying roller 121 and the second conveying roller 122. The specific configuration of the edge guard 13 is not limited, nor is the specific material of the edge guard 13.

[0055] Furthermore, such as Figure 1 As shown, the curing device also includes a take-up roller 3, which is located inside the first cavity 1. The take-up roller 3 is arranged parallel to the conveying roller 12. The take-up roller 3 is rotatably arranged to continuously take up the flexible substrate 10, so that the flexible substrate 10 can be directly taken up after the coating is cured without the need for an additional take-up structure, thus reducing the cost of the curing device. Furthermore, integrating the take-up roller 3 into the first cavity 1 makes the structure more compact, further reducing the area occupied by the curing device.

[0056] Specifically, such as Figures 1 to 3 As shown, the solid baking device also includes a second cavity 2, which is located inside the first cavity 1. The heat in the first cavity 1 will not enter the second cavity 2, so that the first cavity 1 and the second cavity 2 can be separated. This allows the second cavity 2 to cool the flexible substrate 10 heated by the first cavity 1, and the winding roller 3 is rotatably disposed in the second cavity 2.

[0057] By separating the first cavity 1 and the second cavity 2, the temperature inside the second cavity 2 can be lower than the temperature inside the first cavity 1. When the flexible substrate 10 is conveyed into the second cavity 2, the second cavity 2 can cool the flexible substrate 10, so that the surface of the flexible substrate 10 can remain dry and the coating surface on the flexible substrate 10 will not be in a sticky state after heating. This ensures the smooth winding of the flexible substrate 10 and prevents the flexible substrate 10 on the winding roller 3 from sticking together. Furthermore, by integrating the second cavity 2 for cooling into the first cavity 1, the structure of the baking device is made more compact, and the area occupied by the baking device is reduced.

[0058] It is worth noting that whether or not a second cavity 2 is set depends on the specific type of coating. When the flexible substrate 10 is heated by the first cavity 1, the surface of the coating on the flexible substrate 10 does not become sticky. At this time, the surface of the flexible substrate 10 is relatively dry, so there is no need to set a second cavity 2 in the first cavity 1. The flexible substrate 10 can be directly wound onto the winding roller 3.

[0059] Furthermore, a heat insulation component is provided on the outer periphery of the second cavity 2 to isolate the heat inside the first cavity 1, preventing the heat from entering the second cavity 2 through the wall of the second cavity 2, thereby ensuring the cooling effect of the second cavity 2 on the flexible substrate 10. Specifically, the heat insulation component can be heat insulation cotton or other materials with heat insulation properties.

[0060] Specifically, the oven-drying device also includes a cooling component, which is disposed within the second cavity 2. The cooling component is used to cool the interior of the second cavity 2 to improve the cooling effect of the second cavity 2. The cooling component is disposed inside the take-up shaft, and the specific location of the cooling component is not limited here. The cooling component can be a cold air blower or a cooling water pipe, and the specific structure of the cooling component is not limited here, as long as it can ensure the cooling effect of the cooling component on the interior of the second cavity 2.

[0061] Furthermore, a temperature sensor is also provided in the second cavity 2 to detect the temperature inside the second cavity 2. This allows the operation of the cooling component to be adjusted in real time based on the temperature sensor readings, ensuring that the cooling temperature inside the second cavity 2 is suitable. This helps to prevent the flexible substrate 10 from deforming due to a sudden drop in temperature, as the temperature inside the second cavity 2 is too low compared to the temperature inside the first cavity 1.

[0062] Specifically, such as Figure 3 As shown, the heating element 14 includes a heating body 141 and a first fan 142. The heating body 141 and the first fan 142 are respectively disposed in the first cavity 1. The first fan 142 is used to disperse the heat provided by the heating body 141, so that the heat inside the first cavity 1 can be evenly distributed, thereby homogenizing the hot airflow inside the first cavity 1 and achieving uniform heating of the flexible substrate 10 within the first cavity 1. In this embodiment, the heating body 141 is specifically a heating plate, and the heating plate is disposed on the wall of the first cavity 1, with the first fan 142 disposed on the heating plate. In other embodiments, the heating body 141 can also be one or more of an infrared heating element, a heating resistance wire, or a microwave heating element. The specific arrangement structure, quantity, and position of the heating body 141 on the first cavity 1 are not limited, as long as a heat source is provided to the interior of the first cavity 1.

[0063] It is worth noting that there is no limitation on the specific location of the first fan 142. The first fan 142 can be set at any position on the first cavity 1, and there is no limitation on the number of the first fan 142. As long as the first fan 142 and the heating body 141 cooperate with each other to uniformize the temperature inside the first cavity 1, thereby ensuring the uniformity of the overall temperature inside the first cavity 1.

[0064] Furthermore, such as Figure 2 and Figure 3 As shown, the heating device also includes a third chamber 4, which is located at the inlet end of the first chamber 1. The third chamber 4 is used to preheat the flexible substrate 10, so as to realize the staged heating process of the flexible substrate 10 and avoid the problem of deformation of the flexible substrate 10 due to the temperature in the first chamber 1 being too high relative to the room temperature. A feed port 11 is provided at the inlet end of the first chamber 1, through which the preheated flexible substrate 10 in the third chamber 4 enters the first chamber 1; and an air outlet 15 is also provided on the first chamber 1 for the air that has passed through the heated flexible substrate 10 to flow out.

[0065] Specifically, such as Figure 3 As shown, a preheating plate 42 is provided on the wall of the third cavity 4, and a second fan 41 is provided on the preheating plate 42 so that the preheating plate 42 can be heated and the second fan 41 can blow away the heat provided by the preheating plate 42, thereby making the heat in the third cavity 4 uniform and ensuring that the flexible substrate 10 is uniformly preheated in the third cavity 4.

[0066] The specific working process of the solid baking device in this embodiment is as follows:

[0067] First, after the coating is completed on the surface of the flexible substrate 10, the flexible substrate 10 is brought into the third cavity 4 so that the flexible substrate 10 is preheated in the third cavity 4; then, the flexible substrate 10 enters the first cavity 1 through the feed port 11.

[0068] Subsequently, the flexible substrate 10 enters between the first conveying roller 121 and the second conveying roller 122, so as to convey the flexible substrate 10 through the rotation of the first conveying roller 121 and the second conveying roller 122. Since the flexible substrate 10 is always located in the middle of the side guards 13 on both sides during the conveying process, the flexible substrate 10 can be moved to the next first conveying roller 121 and the second conveying roller 122 under the limiting action of the side guards 13, thereby realizing the directional conveying of the flexible substrate 10.

[0069] Simultaneously, the heating body 141 is started to heat up, and the first fan 142 blows away the heat provided by the heating body 141 to make the overall temperature inside the first cavity 1 more uniform, so that the flexible substrate 10 is heated evenly in the first cavity 1. Since the flexible substrate 10 is rolled up to form a vortex structure in the first cavity 1, the heating time of the flexible substrate 10 in the first cavity 1 can be extended, so that the flexible substrate 10 can be heated to the preset heating time to complete the curing process of the coating on the surface of the flexible substrate 10.

[0070] Then, the flexible substrate 10 in the first cavity 1 enters the second cavity 2 so that the flexible substrate 10 can be cooled in the second cavity 2, thereby keeping the surface of the coating of the flexible substrate 10 dry.

[0071] Finally, the cooled flexible substrate 10 in the second cavity 2 is wound onto the take-up roller 3 to complete the continuous winding of the flexible substrate 10, thereby completing the continuous curing process of the flexible substrate 10.

[0072] The above process is a continuous process. The flexible substrate 10 enters the first cavity 1 through the feed port 11, and then is conveyed through a specific path formed by the conveying rollers 12 and the edge guards 13. During the conveying process, the substrate is heated and cured for a preset heating time. Finally, the substrate is cooled and wound up in the second cavity 2. This process does not require machine downtime. The flexible substrate 10 is in a moving state throughout the process, which enables high production efficiency of the flexible substrate 10. The entire curing device has a simple structure and occupies a small area. It is also suitable for heating and curing flexible substrates 10 with different preset heating times, and has good applicability and versatility.

[0073] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
