Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine roller technology, specifically a magnetic roller composite structure with heat dissipation duct. Background Technology

[0002] As the precision of products in various fields increases and die-cut products are widely used, die-cutting technology is receiving more and more attention. Currently, many printing equipment, including die-cutting machines, have die-cutting functions, which are to cut patterns and shapes by rolling die-cutting rollers. Since the patterns and shapes are diverse, the die-cutting rollers need to be replaced during the die-cutting production process. Therefore, the roller structure is an important component of the die-cutting machine, and magnetic rollers are a type of roller that are commonly used in die-cutting machines.

[0003] The existing publication CN218488887U discloses a heat dissipation guide roller for thin film blow molding, including a support shaft, a movable roller, and a wind-powered component. The movable roller is a cylindrical structure with at least one open end. The wall of the movable roller is provided with several air outlets. The movable roller is mounted on the support shaft and rotates around its axis. The open end of the movable roller is provided with a wind-powered component for supplying air into the inner cavity of the movable roller, thereby improving heat dissipation efficiency, reducing the conveying path required for thin film heat dissipation, and reducing space occupation.

[0004] To improve the heat dissipation performance of the rollers, current roller designs incorporate heat dissipation holes on the surface. However, these holes are easily covered, hindering the heat dissipation process and rendering the single surface-opening heat dissipation method ineffective. Current roller designs incorporate airflow devices on both sides to work in conjunction with the surface heat dissipation holes, thereby improving the roller's heat dissipation efficiency. However, due to the complexity of the roller's internal structure, its internal flow space often exhibits an asymmetrical and uneven distribution. This irregularity further affects the uniformity of airflow, resulting in uneven heat dissipation on the roller surface. This uneven heat dissipation can impact the actual die-cutting results, as uneven temperature distribution may lead to inconsistent material processing, thus affecting the quality of the final product.

[0005] Therefore, those skilled in the art have provided a magnetic roller composite structure with a heat dissipation duct to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic roller composite structure with a heat dissipation duct, so as to solve the problem mentioned in the background art that the existing magnetic roller composite structure lacks a heat dissipation duct structure during the heat dissipation process, which is not conducive to the uniform distribution of the flowing air force.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A magnetic roller composite structure with a heat dissipation duct includes: a roller body, an opening fixedly formed on the surface of the roller body, a die-cutting cylinder installed on the outside of the opening, shafts fixedly connected to both ends of the roller body, and a flow-guiding fan blade annularly installed on the outside of the shaft, a heat dissipation fan installed on one side of the flow-guiding fan blade, and an air outlet provided on the side of the heat dissipation fan near the flow-guiding fan blade, a wind cage fixedly installed inside both ends of the roller body, and a heat dissipation groove fixedly formed on the surface of the wind cage, and a flexible fan blade fixedly installed at the end of the wind cage near the center of the roller body.

[0009] As a further improvement of this utility model: the flow-guiding fan blades are distributed in a ring about the symmetrical center line of the axis, and the surface of the flow-guiding fan blades is provided with streamline grooves.

[0010] As a further improvement of this utility model: the heat dissipation grooves are distributed in a ring about the symmetrical center line of the air cage, and a diverting rod is connected to the outer side of the heat dissipation grooves.

[0011] As a further improvement of this utility model: the external structure of the flexible fan blade is streamlined, and the flexible fan blade is distributed in a ring about the symmetrical center line of the wind cage.

[0012] As a further embodiment of this utility model: a baffle plate is fixedly installed in the middle of the inside of the roller body, and the baffle plates are symmetrical about the center line of the roller body.

[0013] As a further improvement of this utility model, the external structure of the baffle plate is bowl-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Shafts are installed on both sides of the roller body to achieve rotation. A ring of air-guiding fins is distributed on the outer side of the shafts, and a cooling fan is installed on one side of the air-guiding fins. The cooling fan blows air towards the air-guiding fins, which then guide the air into the interior of the roller body. The air enters a wind cage inside the roller body, and heat dissipation grooves are formed on the surface of the wind cage. The wind cage gathers the air and distributes it evenly into the interior of the roller body using the surface heat dissipation grooves. The air flows between flexible fins, which have a streamlined structure and are made of aluminum-copper sheets. During operation, the flexible fan blades are agitated by the wind, directing the airflow towards the inner wall of the roller. This, combined with openings on the roller's surface, ensures even air distribution. The air cage features annular heat dissipation grooves and multiple annularly distributed flexible fan blades, which further cut the airflow, ensuring uniform distribution across the roller and improving heat dissipation. This combination of cooling fan, air cage, and flexible fan blades creates a cooling airflow channel within the roller, enhancing its composite structure and overall heat dissipation performance.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a magnetic roller composite structure with heat dissipation duct, including: a roller body 1, an opening 10 fixedly opened on the surface of the roller body 1, and a die-cutting cylinder 5 installed on the outside of the opening 10; a shaft 2 fixedly connected to both ends of the roller body 1, and a flow guide fan 3 annularly installed on the outside of the shaft 2; a heat dissipation fan 4 installed on one side of the flow guide fan 3, and an air outlet 13 provided on the side of the heat dissipation fan 4 near the flow guide fan 3; an air cage 7 fixedly installed inside both ends of the roller body 1, and a heat dissipation groove 11 fixedly opened on the surface of the air cage 7; the flow guide fan 3 is annularly distributed about the symmetrical center line of the shaft 2, and a streamline groove 6 is provided on the surface of the flow guide fan 3; the heat dissipation groove 11 is annularly distributed about the symmetrical center line of the air cage 7, and a diverter bar 12 is connected to the outside of the heat dissipation groove 11.

[0023] Specifically, the cooling fan 4 blows air through the air outlet 13 to the guide fan 3. The surface of the guide fan 3 is provided with streamline grooves 6 to facilitate the smooth entry of air into the guide fan 3. The air is then introduced into the air cage 7 through the guide fan 3. The cage structure of the air cage 7 will gather the blown air, and the air will be evenly distributed in a ring by the heat dissipation grooves 11 evenly distributed on the surface of the air cage 7. The diverting rods 12 provided in the heat dissipation grooves 11 will further divert and cut the air passing through the heat dissipation grooves 11, making the air distribution more uniform.

[0024] A flexible fan blade 8 is fixedly installed at one end of the air cage 7 near the center of the roller body 1. The external structure of the flexible fan blade 8 is streamlined, and the flexible fan blade 8 is distributed in a ring about the center line of symmetry of the air cage 7. A baffle plate 9 is fixedly installed in the middle of the inside of the roller body 1. The baffle plates 9 are symmetrical about the center line of symmetry of the roller body 1, and the external structure of the baffle plate 9 is bowl-shaped.

[0025] Specifically, the air dissipated from the air cage 7 enters between the flexible fan blades 8 inside the roller body 1. The flexible fan blades 8, like the heat dissipation grooves 11, are arranged in a ring about the symmetrical center line of the air cage 7. The flexible fan blades 8 correspond to the heat dissipation grooves 11. The flexible fan blades 8 are made of aluminum-copper sheets, which are made into thin sheets. The flexible fan blades 8 adopt a streamlined structure. When the air enters between the flexible fan blades 8, the airflow will cause the thin flexible fan blades 8 to swing. The swinging flexible fan blades 8 will blow the air toward the surface of the roller body 1 and dissipate it through the openings 10 on the surface of the roller body 1, so that the air is evenly distributed on the surface of the roller body 1, improving the heat dissipation uniformity of the roller body 1 surface. The air blown toward the flexible fan blades 8 will be blocked by the bowl-shaped baffle 9 and deflected back, and then evenly distributed again with the flexible fan blades 8.

[0026] The working principle of this utility model is as follows:

[0027] When using this invention, the cooling fan 4 is started, blowing air through the air outlet 13 towards the guide fan blades 3. Because the guide fan blades 3 have streamlined grooves 6 on their surface, the air is drawn into the air cage 7. The cage structure of the air cage 7 gathers the incoming air, and then the air is evenly distributed in a ring shape by the heat dissipation grooves 11 evenly distributed on the surface of the air cage 7. The diverting rods 12 in the heat dissipation grooves 11 further divert and cut the air passing through the heat dissipation grooves 11, ensuring that the air is more evenly distributed around the roller body 1. Simultaneously, the air dissipated from the air cage 7 enters between the flexible fan blades 8 inside the roller body 1. The flexible fan blades 8 correspond to the heat dissipation grooves 11 and are also distributed in a ring shape about the symmetrical center line of the air cage 7. The flexible fan blades 8 are made of aluminum-copper sheets. This material has good thermal conductivity. The aluminum-copper sheets are made into thin sheets with a streamlined structure, so that when the air enters between the flexible fan blades 8, the flow of the air can cause the thin flexible fan blades 8 to oscillate. The oscillating flexible fan blades 8 will blow the air toward the surface of the roller body 1 and dissipate it through the openings 10 on the surface of the roller body 1. In this way, the air can be evenly distributed on the surface of the roller body 1, further improving the heat dissipation uniformity of the roller body 1 surface. The external structure of the baffle plate 9 is bowl-shaped, which can better guide the direction of airflow. The air blown toward the flexible fan blades 8 will be blocked by the bowl-shaped baffle plate 9 and deflected back, so that the air can form a more stable circulation flow inside the roller body 1, further improving the heat dissipation effect.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
