Description

Technical Field

[0001] This utility model relates to the field of paper forming technology, and in particular to an electrolytic paper manufacturing apparatus. Background Technology

[0002] Electrolytic paper is a functional paper used in electronic components such as capacitors and batteries. Its manufacturing process typically includes steps such as paper forming, pressing and dewatering, and drying and setting. Among these steps, the surface quality and internal density of the paper have a significant impact on its electrical properties during the pressing and drying processes.

[0003] like Figure 1 As shown, existing electrolytic paper manufacturing equipment typically employs a three-roll structure, which uses three parallel pressure rolls to press the paper. The pressed paper is then conveyed to an external drying unit for drying. However, this structure has the following problems: First, the pressing zone is relatively short, resulting in limited stress time for the paper between the rolls, making it difficult to fully compact and causing insufficient paper density. Second, the externally installed dryer occupies a large space and has a complex structure, leading to a large overall footprint and low energy efficiency. Third, because the drying process is separated from the pressing process, the paper is prone to deformation or wrinkling during transport, affecting the quality of the finished product.

[0004] Therefore, there is an urgent need for an electrolytic paper manufacturing device with a more compact structure, continuous pressing and drying processes, and the ability to effectively improve paper density and flatness, in order to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an electrolytic paper manufacturing device with a compact structure that can effectively improve the density and flatness of paper.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An electrolytic paper manufacturing apparatus includes a first pressure roller, a second pressure roller, a drying cylinder, a third pressure roller, and a paper peeling assembly. The first and second pressure rollers are arranged opposite each other, forming a paper feeding channel between them. The drying cylinder is located downstream of the first and second pressure rollers and has an outer surface for supporting the paper and allowing it to move circumferentially along its outer surface. The third pressure roller is located outside the drying cylinder and is arranged opposite to the outer surface of the drying cylinder. A first pressure zone is formed between the drying cylinder and the second pressure roller, and a second pressure zone is formed between the drying cylinder and the third pressure roller. The paper peeling assembly is located after the third pressure roller, close to the outer surface of the drying cylinder, and is used to assist in peeling the paper from the outer surface of the drying cylinder. The paper passes sequentially between the first and second pressure rollers, adheres to the outer surface of the drying cylinder, moves circumferentially, passes sequentially through the first and second pressure zones, and is peeled from the outer surface of the drying cylinder by the paper peeling assembly.

[0007] Furthermore, the paper peeling assembly includes a device base, a main support, a secondary support, and a peeling member. The main support is disposed inside the device base, and the main support and the secondary support are hinged together by a pivot. The peeling member is connected to the secondary support by a hinged support rod on the rear side. The peeling member can maintain a close fit with the outer surface of the drying cylinder during device operation.

[0008] Furthermore, the paper peeling assembly also includes a detection module and a feedback module. The detection module is located close to the peeling member and is used to detect the adhesion state between the peeling member and the outer surface of the drying cylinder. The feedback module adjusts the hinge angle between the main support, the secondary support and the peeling member so that the peeling member remains in contact with the outer surface of the drying cylinder.

[0009] Furthermore, the diameter of the first pressure roller is 630-670mm, the diameter of the second pressure roller is 580-620mm, the diameter of the drying cylinder is 1400-1600mm, and the diameter of the third pressure roller is 575-615mm.

[0010] Furthermore, the outer surface of the drying cylinder is polished.

[0011] Furthermore, the drying cylinder is equipped with a constant temperature heating unit to maintain a stable and constant outer surface.

[0012] Furthermore, the surface of the third pressure roller is covered with a heat-resistant elastic layer.

[0013] The aforementioned electrolytic paper manufacturing apparatus integrates multiple pressing zones and drying modules into a single structure, allowing the paper to undergo multi-stage pressing and simultaneous drying during continuous operation. This significantly extends the pressing zone length, improves the compaction effect, and solves the problems of short pressing time and insufficient paper density in existing devices. Simultaneously, by using a drying cylinder instead of a separate drying device, continuous pressing and drying operations are achieved, effectively preventing paper deformation and wrinkling during transport and improving the smoothness of the finished paper. Furthermore, the apparatus is compact, occupies a small area, and has a short heat transfer path, significantly improving energy efficiency and overcoming the shortcomings of complex structures and low energy utilization efficiency in existing technologies.

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 2 As shown, this application provides an electrolytic paper manufacturing apparatus, which includes a first pressure roller 1, a second pressure roller 2, a drying cylinder 3, a third pressure roller 4, and a paper peeling assembly 5.

[0017] Specifically, the first pressure roller 1 and the second pressure roller 2 are arranged opposite to each other, forming a paper feeding channel between them; the drying cylinder 3 is located downstream of the first pressure roller 1 and the second pressure roller 2, and has an outer surface for supporting the paper and allowing the paper to run circumferentially along its outer surface; the third pressure roller 4 is arranged outside the drying cylinder 3 and opposite to the outer surface of the drying cylinder 3; the drying cylinder 3 and the second pressure roller 2 form a first pressing zone, and the drying cylinder 3 and the third pressure roller 4 form a second pressing zone; the paper peeling assembly 5 is arranged after the third pressure roller 4, close to the outer surface of the drying cylinder 3, and is used to assist the paper in peeling off from the outer surface of the drying cylinder 3.

[0018] The paper passes between the first pressure roller 1 and the second pressure roller 2 in sequence, and is attached to the outer surface of the drying cylinder 3. It runs circumferentially, passes through the first pressure zone and the second pressure zone in sequence, and is peeled off from the outer surface of the drying cylinder 3 by the paper peeling component 5.

[0019] The above-mentioned design extends the paper's path under high pressure and high temperature, effectively improving pressing strength and drying efficiency, thereby significantly enhancing the density and flatness of the electrolytic paper. Simultaneously, by integrating the pressing and drying functions into the same device, the structure is more compact, saving equipment space, reducing energy consumption, and improving energy utilization. Furthermore, the peeling component effectively prevents paper from sticking or tearing at the end of the drying cylinder, further ensuring the quality of the finished product.

[0020] The paper peeling assembly 5 includes a device base 51, a main support 52, a secondary support 53, and a peeling member 54. The main support 52 is disposed within the device base 51, and the main support 52 and the secondary support 53 are hinged together via a pivot. The peeling member 54 is connected to the secondary support 53 via a rear hinged support rod. During device operation, the peeling member 54 can maintain a close fit with the outer surface of the drying cylinder 3. The multi-stage hinged connection improves the flexibility of the peeling member's movement and its adaptability to different paper conditions, effectively addressing poor adhesion caused by changes in paper thickness, humidity, or thermal expansion of the drying cylinder. The peeling process is continuous and stable, significantly reducing paper damage rate and improving the finished product qualification rate.

[0021] The paper peeling assembly 5 also includes a detection module and a feedback module. The detection module is located close to the peeling member 54 and is used to detect the adhesion state between the peeling member 54 and the outer surface of the drying cylinder 3. The feedback module adjusts the hinge angle between the main support 52, the secondary support 53, and the peeling member 54 to maintain adhesion between the peeling member 54 and the outer surface of the drying cylinder 3. By integrating the detection and feedback control system, real-time intelligent adjustment of the adhesion state of the peeling member to the drying cylinder surface is achieved, significantly improving the system's adaptability and automation level. This avoids peeling failure, paper tearing, or localized overheating caused by poor adhesion, thereby improving paper processing quality and production stability.

[0022] The diameter of the first pressure roller 1 is 630-670mm, the diameter of the second pressure roller 2 is 580-620mm, the diameter of the drying cylinder 3 is 1400-1600mm, and the diameter of the third pressure roller 4 is 575-615mm. This arrangement improves the uniformity of the pressure zone length and overall pressure distribution, allowing the paper to be more fully dehydrated and densified during the pressing process, thus improving the paper thickness uniformity and surface smoothness.

[0023] The outer surface of the drying cylinder 3 is polished, which helps to improve heat transfer efficiency; at the same time, it improves the flatness and surface quality of the paper.

[0024] The drying cylinder 3 is equipped with a constant temperature heating unit to maintain the stability of the outer surface, thereby reducing the problem of paper thermal expansion and contraction caused by temperature difference and improving the paper flatness and dimensional stability.

[0025] The surface of the third pressure roller 4 is coated with a heat-resistant elastic layer, which significantly improves the adaptability and cushioning performance of the second pressure zone, helping to improve the uniformity of paper compaction and overall forming quality. The elastic layer can also effectively compensate for the thermal expansion error of the roller body, reduce the risk of damage to the paper and drying cylinder from hard contact, and extend the service life of the equipment.

[0026] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
