Description

Technical Field

[0001] This utility model relates to the field of embossing equipment technology, specifically an embossing roller with a built-in rapid cooling mechanism. Background Technology

[0002] Traditional embossing roller cooling methods mostly rely on circulating fluid for cooling, requiring a complex circulating fluid system including pumps, pipes, radiators, and many other components. This not only increases the initial purchase cost of the equipment but also makes daily maintenance cumbersome. For example, it is necessary to regularly check the pump's operating status, whether the pipes are blocked or leaking, and the level and concentration of the circulating fluid. If any component malfunctions, repairs are difficult and time-consuming, affecting production schedules. The circulating fluid cooling system consumes electricity to drive the pump, and the circulating fluid gradually deteriorates during use, requiring regular replacement, increasing operating costs and reducing reliability. Furthermore, circulating fluid leaks can pollute the surrounding environment and materials, further increasing costs. Utility Model Content

[0003] The purpose of this invention is to provide an embossing roller with a built-in rapid cooling mechanism, which can quickly conduct heat out, allowing the heat to be dissipated more efficiently into the surrounding environment, thereby achieving rapid cooling of the embossing roller. Compared with traditional embossing rollers that use circulating liquid for cooling, it has a simple structure, fewer parts, easy maintenance, high reliability, low failure rate, and low initial and operating costs, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An embossing roller with a built-in rapid cooling mechanism includes a roller, with fixed plates fixedly installed at both ends of the roller, and a connecting shaft fixedly connected to the middle of the two fixed plates. A heat-conducting cylinder is provided inside the roller, with the outer surface of the heat-conducting cylinder in close contact with the inner surface of the roller. At least three heat-conducting fins are fixedly connected to both ends of the heat-conducting cylinder. The fixed plates have through holes corresponding to the heat-conducting fins, and the heat-conducting fins pass through the through holes one by one. A first heat dissipation plate is fixedly installed on both connecting shafts. The heat-conducting fins on the same side are jointly fixedly installed on the first heat dissipation plate on the same side. A plurality of arc-shaped fins with equal angles are fixedly connected to the side of the first heat dissipation plate away from the fixed plates.

[0006] Preferably, a thermally conductive silicone grease layer is provided between the inner surface of the roller and the outer surface of the heat-conducting cylinder.

[0007] Preferably, the outer surface of the heat-conducting cylinder is provided with at least two vertically oriented protrusions at equal angles, and the inner surface of the roller is provided with grooves corresponding to the protrusions, with each protrusion located in a corresponding groove.

[0008] Preferably, both ends of the roller are fixedly connected to a fixing ring, and the two fixing rings are respectively fixedly installed on the fixing plate on the same side by bolts.

[0009] Preferably, each of the two first heat sinks is fixedly connected with a heat-conducting sleeve corresponding to the heat-conducting sheet, and the heat-conducting sheet is inserted into the heat-conducting sleeve in a one-to-one correspondence.

[0010] Preferably, a second heat sink is fixedly installed on both connecting shafts, and the arc-shaped fins on the same side are jointly fixedly installed on the second heat sink on the same side.

[0011] Preferably, each of the two second heat sinks is fixedly connected with a connecting sleeve, which is sleeved on the connecting shaft on the same side and fixedly installed by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This embossing roller with built-in rapid cooling mechanism utilizes a heat-conducting cylinder inside the roller. The outer surface of the heat-conducting cylinder is in close contact with the inner surface of the roller, enabling rapid heat conduction from the roller during operation. The heat-conducting fins at both ends of the heat-conducting cylinder pass through through holes in the fixed plate and are fixedly connected to the first heat dissipation plate. The arc-shaped fins on the first heat dissipation plate increase the heat dissipation area, allowing heat to be dissipated more efficiently into the surrounding environment. This achieves rapid cooling of the embossing roller, preventing excessive temperature from affecting its normal working performance and service life. It also helps improve the quality of embossing. Compared to traditional embossing rollers that use circulating fluid for cooling, this design is simpler in structure, has fewer parts, is easier to maintain, and all parts are mechanical structures, unaffected by liquids.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 This utility model provides an embossing roller with a built-in rapid cooling mechanism, including a roller 1. Both ends of the roller 1 are fixedly mounted with fixed disks 2. The middle of the two fixed disks 2 is fixedly connected with a connecting shaft 3. A heat-conducting cylinder 4 is provided inside the roller 1. The outer surface of the heat-conducting cylinder 4 is tightly attached to the inner surface of the roller 1. At least three heat-conducting plates 5 are fixedly connected to both ends of the heat-conducting cylinder 4. The fixed disks 2 are provided with through holes 201 corresponding to the heat-conducting plates 5. The heat-conducting plates 5 pass through the through holes 201 one by one. A first heat dissipation plate 6 is fixedly mounted on both connecting shafts 3. The heat-conducting plates 5 on the same side are fixedly mounted on the first heat dissipation plate 6 on the same side. Multiple arc-shaped fins 7 with equal angles are fixedly connected to the side of the first heat dissipation plate 6 away from the fixed disks 2.

[0023] The embossing roller with a built-in rapid cooling mechanism has a heat-conducting cylinder 4 inside the roller 1. The outer surface of the heat-conducting cylinder 4 is in close contact with the inner surface of the roller 1, which can quickly conduct the heat generated by the roller 1 during operation. The heat-conducting plates 5 at both ends of the heat-conducting cylinder 4 pass through the through holes 201 on the fixed plate 2 and are fixedly connected to the first heat dissipation plate 6. The arc-shaped fins 7 on the first heat dissipation plate 6 increase the heat dissipation area, so that the heat can be dissipated to the surrounding environment more efficiently, thereby achieving rapid cooling of the embossing roller. This avoids the normal working performance and service life of the embossing roller due to excessive temperature, and also helps to improve the quality of embossing. Compared with the traditional embossing roller that uses circulating liquid for cooling, it has a simple structure, fewer parts, and is easy to maintain. Moreover, all parts are mechanical structures and are not affected by liquid. It has high reliability, low failure rate, low initial and operating costs, no need to purchase circulating liquid-related equipment and additional energy, and can also avoid liquid contamination of materials. It has good safety, no liquid leakage and electrical safety hazards, and is safer to use.

[0024] A thermally conductive silicone grease layer 8 is provided between the inner surface of the roller 1 and the outer surface of the heat-conducting cylinder 4. The thermally conductive silicone grease has good thermal conductivity and can fill the tiny gap between the roller 1 and the heat-conducting cylinder 4, reduce thermal resistance, and further improve the heat conduction efficiency from the roller 1 to the heat-conducting cylinder 4, making the cooling effect more significant and ensuring that the embossing roller can maintain a stable working state in a high-temperature working environment. At least two vertically oriented protrusions 401 are provided on the outer surface of the heat-conducting cylinder 4 at equal angles. Corresponding grooves 101 are formed on the inner surface of the roller 1. The protrusions 401 are located in the grooves 101 one-to-one. The cooperation between the protrusions 401 and the grooves 101 makes the connection between the heat-conducting cylinder 4 and the roller 1 more stable, preventing the heat-conducting cylinder 4 from rotating or shifting relative to the roller 1. It also increases the contact area between the heat-conducting cylinder 4 and the roller 1, ensuring that the heat-conducting cylinder 4 can stably conduct the heat from the roller 1.

[0025] To enhance heat dissipation and facilitate the installation, disassembly, and maintenance of the built-in rapid cooling mechanism, two fixing rings 9 are fixedly connected to both ends of the roller 1. The two fixing rings 9 are respectively bolted to the fixing plate 2 on the same side. This connection method is simple in structure and easy to install and disassemble. Each of the two first heat dissipation plates 6 is fixedly connected to a heat-conducting sleeve 10 corresponding to the heat-conducting sheet 5. The heat-conducting sheet 5 is inserted into the heat-conducting sleeve 10 in a one-to-one correspondence. Thermal grease can also be added to the heat-conducting sleeve 10 to eliminate gaps between the heat-conducting sheet 5 and the heat-conducting sleeve 10, improving conduction efficiency. The connection via the heat-conducting sleeve 10 increases the contact area between the heat-conducting sheet 5 and the first heat dissipation plate 6, allowing heat to be conducted more efficiently from the heat-conducting sheet 5 to the first heat dissipation plate 6, further improving heat dissipation efficiency and helping to reduce the temperature of the embossing roller more quickly. Furthermore, the heat-conducting sheet 5 and the heat-conducting sleeve 10 are easy to separate. A second heat dissipation plate 11 is fixedly installed on each of the two connecting shafts 3. Arc-shaped fins 7 on the same side are also fixedly installed on the second heat dissipation plate 11 on the same side. The space between the first heat dissipation plate 6 and the second heat dissipation plate 11 forms a relatively independent air duct. This air duct guides the airflow, causing it to flow in a specific direction, thus allowing more airflow to concentrate on the arc-shaped fins 7, increasing the contact area and time with the fins. It also promotes the rapid rise or expulsion of hot air while simultaneously introducing relatively cool air, creating a continuous exchange of hot and cold air, accelerating heat dissipation, and further enhancing the heat dissipation effect. This forms a more complete heat dissipation system, ensuring that the embossing roller maintains a good temperature during long-term high-load operation. Connecting sleeves 12 are fixedly connected to each of the two second heat dissipation plates 11. The connecting sleeves 12 are fitted onto the connecting shafts 3 on the same side and fixed with bolts, facilitating the installation and removal of the first heat dissipation plate 6 and the second heat dissipation plate 11. When replacement or maintenance is required, only the bolts need to be removed, improving the convenience of equipment maintenance.

[0026] When installing the embossing roller with the built-in rapid cooling mechanism, apply thermal grease to the outer surface of the heat-conducting cylinder 4 or the inner surface of the roller 1. Place the heat-conducting cylinder 4 into the roller 1, ensuring that the vertical equal-angle protrusions 401 on the outer surface of the heat-conducting cylinder 4 are embedded in the grooves 101 pre-opened on the inner surface of the roller 1. Fix the fixing plate 2 with the connecting shaft 3 to the fixing ring 9 on the roller 1 with bolts. At this time, the heat-conducting plates 5 at both ends of the heat-conducting cylinder 4 pass through the through holes 201 opened on the fixing plate 2 one by one. Align the heat-conducting sleeve 10 on the first heat sink 6 with the heat-conducting plate 5, so that the heat-conducting plate 5 is inserted into the heat-conducting sleeve 10 one by one. Fix the connecting sleeve 12 on the second heat sink 11 to the connecting shaft 3 with bolts. When disassembling the embossing roller with the built-in rapid cooling mechanism, loosen the bolts between the fixing connecting sleeve 12 and the connecting shaft 3, remove the second heat dissipation plate 11 together with the first heat dissipation plate 6 from the connecting shaft 3, then loosen the bolts between the fixing ring 9 and the fixing plate 2, remove the fixing plate 2 together with the connecting shaft 3 from the fixing ring 9, and the heat conduction cylinder 4 can be removed from the inside of the roller 1.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
