Description

Technical Field

[0001] The utility model relates to the technical field of plate-making machines, and particularly relates to a cooling mechanism for a plate-making machine. Background Technique

[0002] A plate-making machine adopts a digital workflow, directly converts text and images into digital form, directly generates printing plates, and omits the processes of using films as materials, manual plate-making, and semi-automatic or automatic plate-making processes; it is a portable tool.

[0003] During the working process of a plate-making machine, a single original laser beam generated by a laser is split into multiple extremely thin laser beams through a multi-channel optical fiber or a complex high-speed rotating optical beam splitting system. After modulating the brightness and darkness changes of the laser beam, it becomes a controlled beam. Then, after focusing, hundreds of micro-laser beams directly irradiate the surface of the printing plate for plate-making work. After scanning and plate-making, a latent image of the image is formed on the printing plate. After development, the image information on the computer screen is restored on the printing plate for direct printing by an offset printing machine. During this process, when the laser beam adjusts the brightness and darkness changes to engrave the surface of the printing plate, due to the different numbers and brightness and darkness levels of the laser beams, the laser heat generated on the surface of the printing plate is also different. Moreover, during the process of the laser beam emitting laser to generate heat during plate-making, many electrical components need to cooperate with each other to work. The electrical components inside the plate-making machine work to provide the plate-making working conditions for the laser beam. Therefore, a large amount of working heat is easily generated by the electrical components inside the plate-making machine and accumulates inside the plate-making machine device, thereby affecting the laser beam's laser heat generation and plate-making work on the surface of the printing plate. Therefore, a cooling mechanism for a plate-making machine is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cooling mechanism for a plate-making machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0012] In the present utility model, through the arrangement of the motor, the intake fan blade, the exhaust fan blade, the holes and the dust-proof and breathable net, during the operation of the electrical components inside the plate-making machine, the motor is started.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0021] A cooling mechanism for a plate-making machine, including a chassis 1. A dust-proof and breathable net 2 is fixedly connected to the outer side of the left end of the chassis 1. A fixed column 3 is fixedly connected to the outer side of the chassis 1. A bearing 4 is fixedly connected to the outer side of the fixed column 3. An intake fan blade 5 is fixedly connected to the outer side of the bearing 4. A first runner 6 is fixedly connected to the outer side of the bearing 4. A first belt 7 is slidably connected to the outer side of the first runner 6. A second runner 8 is fixedly connected to the inner side of the first belt 7. A rotating shaft 9 is fixedly connected to the inner side of the second runner 8. A motor 10 is fixedly connected to the end of one side of the rotating shaft 9. A third runner 11 is fixedly connected to the outer side of the rotating shaft 9. A second belt 12 is slidably connected to the outer side of the third runner 11. A fourth runner 13 is slidably connected to the inner side of the second belt 12. A bearing 4 is fixedly connected to the inner side of the fourth runner 13. An exhaust fan blade 16 is fixedly connected to the outer side of the bearing 4. A cylindrical shell 14 is fixedly connected to the outer side of the right end of the chassis 1. A sliding hole 15 is provided inside the cylindrical shell 14.

[0022] Holes 17 are provided inside the chassis 1, and the holes 17 provided inside the right end of the chassis 1 are evenly distributed inside the connection circle area between the cylindrical shell 14 and the chassis 1, facilitating the rapid replacement of the air containing heat inside the chassis 1. The number of the fixed columns 3 and the bearings 4 is both 2, and the fixed columns 3 are symmetrically and fixedly connected to the outer side of the chassis 1, facilitating the fixation of the intake fan blade 5 and the exhaust fan blade 15 on the same horizontal line. The number of the sliding holes 15 is 2 in total, and the sliding holes 15 are symmetrically arranged inside the cylindrical shell 14. The second belt 12 is slidably connected inside the sliding holes 15, facilitating the third runner 11 to drive the fourth runner 13 to rotate through the second belt 2. The first runner 6 is arranged on the left side of the intake fan blade 5, and the fourth runner 13 is arranged on the left side of the exhaust fan blade 16. The intake fan blade 5 is close to the outer side of the chassis 1, facilitating the intake fan blade 5 to blow the outside air into the inside of the chassis 1 and facilitating the exhaust fan blade 16 to quickly extract the air inside the chassis 1.

[0023] Workflow: During use, the device is powered on through an external power supply. During the process of using the plate-making machine to make plates, the internal electrical components of the plate-making machine operate to provide the engraving working conditions for the laser beam. Therefore, a large amount of working heat is generated by the internal electrical components of the plate-making machine. Start the motor 10. During the process of the motor 10 rotating outside the chassis 1, on the outer sides of the ends of the main shaft of the motor 10, a second runner 8 and a third runner 11 are fixedly connected to the outside of the rotating shaft 9. The second runner 8 and the third runner 11 are driven by the motor 10 to rotate the rotating shaft 9, so that the second runner 8 and the third runner 11 rotate simultaneously. A first belt 7 is slidably connected to the outside of the second runner 8, and the second runner 8 is connected to the first runner 6 through the first belt 7. Thus, during the rotation of the second runner 8, the second runner 8 drives the first runner 6 to rotate through the first belt 7. A second belt 12 is slidably connected to the outside of the third runner 11, and the third runner 11 is connected to the fourth runner 13 through the second belt 12. Thus, the third runner 11 can drive the fourth runner 13 to rotate through the second belt 12. The first runner 6 and the fourth runner 13 are respectively fixedly connected to the outside of the fixed columns 3 symmetrically arranged on both sides of the chassis 1 through bearings 4. Thus, during the process of the second runner 8 driving the first runner 6 to rotate and the third runner 11 driving the fourth runner 13 to rotate, the first runner 6 and the fourth runner 13 simultaneously drive the bearings 4 fixedly connected to the outside of the fixed columns 3 to rotate. On the outer sides of the two bearings 4, an intake fan blade 5 and an exhaust fan blade 16 are respectively fixedly connected. During the rotation of the intake fan blade 5 at the left end of the chassis 1, the outside air is blown into the inside of the chassis 1 through the hole 17 opened on the inner side of the left end of the chassis 1. A dust-proof breathable net 2 is fixedly connected to the outside of the left end of the chassis 1, which can effectively prevent the dust in the air from being blown into the inside of the plate-making machine during the operation of the intake fan blade 5, thus affecting the normal operation of the plate-making machine. While the intake fan blade 5 is working, the exhaust fan blade 16 inside the cylindrical shell 14 fixedly connected to the outside of the right end of the chassis 1 operates simultaneously. The cylindrical shell 14 can reduce the working range of the exhaust fan blade 16 while enhancing the exhaust intensity during the operation of the exhaust fan blade 16. Two sliding holes 15 are opened inside the cylindrical shell 14 to facilitate the third runner 11 to drive the fourth runner 13 to rotate through the second belt 12. Thus, one end of the chassis 1 sends air through the intake fan blade 5, and the other end extracts air through the exhaust fan blade 16, effectively accelerating the air flow speed inside the plate-making machine, so that the heat generated by the internal electrical components of the plate-making machine can be quickly discharged, thereby achieving the effect of rapid cooling and temperature reduction, and further ensuring the good plate-making effect of the plate-making machine.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
