[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides an aluminum coating roller of a thin film vacuum aluminum coating device, such as Figure 1-4 As shown, it includes an inner roller 1 and an outer roller 2, the outer roller 2 is sleeved on the outer side of the inner roller 1, and a cavity for water circulation is set between the inner roller 1 and the outer roller 2; a heat sink is arranged in the cavity; wherein the heat sink includes: a cold water pipe 301 tightly attached to the outer side of the inner roller 1, the cold water pipe 301 is wound from one end point of the inner roller 1 to the other end point along its longitudinal axis; a water inlet end 302 and a water outlet end 303 are arranged at the ends of both sides of the outer roller 2, the water inlet end 302 is connected with one end of the cold water pipe 301, and the water outlet end 303 is connected with the other end of the cold water pipe 301; two cooling fans 304 are arranged on the inner side of the outer roller 2, and the two fans are arranged at the intersection of the outer roller 2 away from each other; an air flow channel for heat dissipation of the cavity is formed between the two cooling fans 304.

[0021] It should be noted that since the roller generates a large amount of heat during operation, the performance of the inner roller 1 itself will be reduced, and the quality and uniformity of the aluminum coating may be affected, thereby affecting the quality of the final product and production efficiency. In this solution, the heat generated by the inner roller 1 is quickly removed by circulating cold water in the cold water pipe 301. The cold water pipe 301 is close to the surface of the inner roller 1, and the heat is transferred to the cold water by heat conduction. The cold water is then circulated and pumped to an external cooling device for cooling. This method can quickly and effectively reduce the temperature of the inner roller 1. At the same time, the air cooler 304 further enhances the heat dissipation effect through the air flow channel, and further removes the heat dissipated in the cold water pipe 301 by air convection and radiation heat dissipation. This method can not only make up for the deficiency of water cooling, but also can independently undertake the heat dissipation task when the equipment is shut down or running at low load, thereby improving the energy efficiency of the equipment.

[0022] Specifically, in this embodiment, the scheme mainly includes an inner roller 1 and an outer roller 2, wherein the outer roller 2 is sleeved on the outer side of the inner roller 1, and a cavity for water flow is provided between the inner roller 1 and the outer roller 2; a heat sink is provided in the cavity; cooling water enters the cold water pipe 301 from the water inlet end 302, absorbs the heat generated by the outer side of the inner roller 1 when passing through the inner roller 1, and then flows out from the water outlet end 303. In this process, the cold water circulates continuously, continuously takes away the heat of the inner roller 1, and realizes effective water cooling and heat dissipation;

[0023] When the air coolers 304 are started, the airflow they generate passes through the cavity between the outer roller 2 and the inner roller 1 to form an air flow channel. This air flow channel not only helps to further take away the heat dissipated in the cold water pipe 301, but also dissipates heat through air convection and radiation, thereby improving the overall heat dissipation effect. The cold water pipe 301 and the air cooler 304 work together to form a comprehensive heat dissipation system of water cooling and air cooling. The cold water pipe 301 mainly undertakes most of the heat dissipation tasks, and quickly takes away the heat of the inner roller 1 through the circulating cold water, while the air cooler 304 plays a role in auxiliary heat dissipation, and further enhances the heat dissipation effect through the air flow channel, ensuring that the inner roller 1 can maintain a stable operating state in a high-temperature working environment, so that the aluminum-plated roller can effectively dissipate heat and maintain a stable temperature during operation, thereby improving the working efficiency of the equipment and the quality of aluminum plating.

[0024] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the side wall of the outer roller 2 is provided with a plurality of heat dissipation fins 4, and the plurality of heat dissipation fins 4 are arranged in a ring shape.

[0025] In this embodiment, the heat dissipation fins 4 are provided to ensure that the aluminum-plated roller can maintain better heat dissipation performance in a high-temperature working environment, thereby improving the stability and efficiency of the equipment, and also helping to reduce equipment failures caused by overheating and extending the service life of the aluminum-plated roller.

[0026] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a plurality of heat dissipation holes 5 are provided through the outer sides of the ends of both sides of the outer roller 2. The plurality of heat dissipation holes 5 are connected to the cavity and filters are provided in the holes.

[0027] In this embodiment, since the cavity is connected to the heat dissipation hole 5, the heat can be directly discharged to the external environment through the heat dissipation hole 5. In this process, the filter plays a key role. On the one hand, it prevents dust and impurities from entering the cavity and keeps the heat dissipation hole 5 and the cavity clean; on the other hand, it allows heat to pass through, ensuring that the heat dissipation channel is unobstructed.

[0028] This design not only enhances the heat dissipation capacity of the equipment, but also improves its stability and reliability. Through the filtering effect of the filter, the heat dissipation holes 5 are not easily blocked, ensuring the smooth flow of the heat dissipation channel, so that the equipment can maintain a stable operating state even in a high-temperature working environment.

[0029] In a further preferred embodiment of the present invention, Figure 3-4 As shown, sealing gaskets 6 are provided at both ends of the outer roller 2 .

[0030] In this embodiment, the main function of the sealing gasket 6 is to enhance the sealing between the outer roller 2 and adjacent components to prevent impurities such as gas, liquid or dust from entering the interior of the equipment during operation and affecting the normal operation of the equipment.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the outer side of the cold water pipe 301 is covered with an insulating layer.

[0032] In this embodiment, by wrapping the outer side with an insulating layer, the cold water pipe 301 can effectively improve the thermal insulation performance and electrical insulation performance, ensuring that the equipment operates in an efficient and safe state. This not only helps to save energy and reduce operating costs, but also improves the service life of the equipment and the user experience.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the surfaces of the inner roller 1 and the outer roller 2 are covered with an aluminum coating.

[0034] In this embodiment, the aluminum plating layer can improve the thermal conductivity and corrosion resistance of the two rollers, thereby optimizing the process.

[0035] Working principle: Cooling water enters the cold water pipe 301 from the water inlet 302, absorbs the heat generated by the outer side of the inner roller 1 when passing through it, and then flows out from the water outlet 303. In this process, the cold water circulates continuously, continuously taking away the heat of the inner roller 1, and realizing effective water cooling and heat dissipation;

[0036] When the air coolers 304 are started, the airflow they generate passes through the cavity between the outer roller 2 and the inner roller 1 to form an airflow channel. This airflow channel not only helps to further take away the heat dissipated in the cold water pipe 301, but also dissipates heat through air convection and radiation, thereby improving the overall heat dissipation effect. The cold water pipe 301 and the air cooler 304 work together to form a comprehensive heat dissipation system of water cooling and air cooling. The cold water pipe 301 mainly undertakes most of the heat dissipation tasks, and quickly takes away the heat of the inner roller 1 through the circulating cold water, while the air cooler 304 plays a role in auxiliary heat dissipation. The heat dissipation effect is further enhanced through the airflow channel, ensuring that the inner roller 1 can maintain a stable operating state in a high-temperature working environment, so that the aluminum-plated roller can effectively dissipate heat and maintain a stable temperature during operation, thereby improving the working efficiency of the equipment and the quality of aluminum plating.

[0037] Since the cavity is connected to the heat dissipation hole 5, the heat can be directly discharged to the external environment through the heat dissipation hole 5. In this process, the filter plays a key role. On the one hand, it prevents dust and impurities from entering the cavity and keeps the heat dissipation hole 5 and the cavity clean; on the other hand, it allows heat to pass through, ensuring that the heat dissipation channel is unobstructed.

[0038] This design not only enhances the heat dissipation capacity of the equipment, but also improves its stability and reliability. Through the filtering effect of the filter, the heat dissipation holes 5 are not easily blocked, ensuring the smooth flow of the heat dissipation channel, so that the equipment can maintain a stable operating state even in a high-temperature working environment.

[0039] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and 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 will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
