[0002] Printing and packaging refers to a series of technological processes in which information such as text, patterns, and colors is printed on various materials (such as paper, plastic, metal, fabric, etc.) through printing technology, and then processes such as cutting, folding, bonding, and shaping are carried out to finally make product packaging. Printing and packaging are widely used in the packaging of commodities such as books, newspapers, magazines, food, daily necessities, and electronic products. When printing machines and other related equipment are operating, especially under high-speed operation, a large amount of heat will be generated. Overheating will affect the performance, accuracy, and lifespan of the equipment. Therefore, a heat dissipation device for printing and packaging machinery is required.

[0003] During the use of traditional heat dissipation devices for printing and packaging machinery, the heat generated by the equipment is transferred to the radiator, and then the heat is carried away by air flow or coolant, thereby reducing the operating temperature of the equipment. This process ensures that the equipment operates at an appropriate temperature and avoids the impact of overheating on performance and lifespan.

[0004] However, during heat dissipation, the problem that traditional heat dissipation devices only circulate cooling water, but when the temperature of the cooling water is too high, only rely on natural cooling and the heat dissipation efficiency is low when the ambient temperature is too high, affects the heat dissipation efficiency of the heat dissipation device for printing and packaging machinery.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a heat dissipation device for a printing and packaging machine, comprising a printing machine 1, a box body 2 fixedly connected to one side of the printing machine 1, a top cover 3 fixedly connected to the top of the box body 2, a semiconductor refrigeration plate 9 fixedly connected inside the box body 2, a temperature guiding plate 4 fixedly connected to the top of the printing machine 1, a coil pipe 7 fixedly connected inside the temperature guiding plate 4, a heat dissipation port 11 opened inside the box body 2, a partition plate 8 fixedly connected inside the printing machine 1, a semiconductor refrigeration plate 9 fixedly connected inside the partition plate 8, a temperature guiding block 10 fixedly connected to one side of the semiconductor refrigeration plate 9, and a heat dissipation component arranged on the other side of the semiconductor refrigeration plate 9, the heat dissipation component being used to increase the contact area between the heat dissipation surface of the semiconductor refrigeration plate 9 and the air. A water outlet pipe 6 is fixedly connected inside the top cover 3, a water pump 5 is fixedly connected to one end of the water outlet pipe 6, the input end of the water pump 5 is connected to the water outlet pipe 6, and the output end of the water pump 5 is connected to one end of the coil pipe 7. The other end of the coil pipe 7 is fixedly connected inside the top cover 3. The heat dissipation component includes a heat dissipation plate 12, heat dissipation columns 13, and a heat dissipation fan 14. The heat dissipation fan 14 is arranged inside the box body 2. The heat dissipation columns 13 are fixedly connected to one side of the heat dissipation plate 12 in a rectangular array. The heat dissipation plate 12 is fixedly connected to the other side of the semiconductor refrigeration plate 9;

[0031] Specifically, when the heat generated during the operation of the printing machine 1 is gradually conducted to the temperature guiding plate 4, at this time, the input end of the water pump 5 pumps out the cooling water stored inside the box body 2 through the connected water outlet pipe 6 and pumps it into the coil pipe 7 through the output end of the water pump 5, so that the cooling water can flow through the temperature guiding plate 4 and take away the accumulated heat on it. After passing through the temperature guiding plate 4, the cooling water flows back into the box body 2 through the coil pipe 7 again. At this time, the system starts to dissipate heat from the cooling water. The low temperature generated by the refrigerating surface of the semiconductor refrigeration plate 9 during operation is conducted to the temperature guiding block 10, thereby directly cooling the cooling water. At the same time, the heating surface of the semiconductor refrigeration plate 9 conducts heat to the outer wall of the heat dissipation column 13 through the heat dissipation plate 12, increasing its contact area with the air to improve the heat dissipation efficiency. In order to accelerate the dissipation of heat, the heat dissipation fan 14 blows the external air filtered by the dust-proof net 17 towards the outer wall of the heat dissipation column 13, thereby taking away the heat, and finally discharging the hot air out of the box body 2 through the heat dissipation port 11, so that the temperature of the entire system can be controlled within a reasonable range to ensure the normal operation of the printing machine 1.

[0032] Refer to Figure 3, a magnet 15 is fixedly connected inside the box body 2. The magnets 15 are arranged in a circular array and fixedly connected inside the box body 2. A fixing ring 18 is arranged on one side of the box body 2. A magnet 2 is fixedly connected inside the fixing ring 18. An installation ring 16 is arranged inside the fixing ring 18. A dust-proof net 17 is fixedly connected inside the installation ring 16. A sealing ring 20 is fixedly connected to one side of the fixing ring 18. One side of the sealing ring 20 is attached to the outer wall of the box body 2. A sealing ring 21 is fixedly connected to one side of the fixing ring 18. One side of the sealing ring 21 is attached to the outer wall of the installation ring 16. The magnets 2 are fixedly connected in a circular array inside the fixing ring 18. The magnet 2 adsorbs to the outer wall of the magnet 15;

[0033] Specifically, when the dust-proof net 17 needs to be cleaned or replaced, the operation is very simple. First, simply pull the fixing ring 18 off the box body 2 easily. This is due to the strong adsorption connection between the fixing ring 18 and the box body 2 through the magnet 2 and the magnet 15, ensuring stable connection during use and convenient disassembly. Next, after removing the dust-proof net 17 from the installation ring 16, it can be thoroughly cleaned or replaced. When reinstalling, effective sealing is achieved between the fixing ring 18 and the box body 2 through the sealing ring 20, further enhancing the stability and sealing of the connection. At the same time, the fixing ring 18 and the installation ring 16 are sealed through the sealing ring 21 to prevent dust from being sucked into the box body 2 through the gap when the cooling fan 14 is running, thus ensuring the cleanliness of the internal environment and avoiding dust pollution from affecting the heat dissipation effect of the equipment and the reliability of long-term operation.

[0034] Working principle: When using the heat dissipation device of this printing and packaging machine, first, the heat generated by the printing press 1 during operation is conducted to the heat conduction plate 4. Subsequently, the input end of the water pump 5 pumps out the cooling water inside the box body 2 through the water outlet pipe 6 and pumps it into the coil 7 through the output end of the water pump 5, so that the cooling water flows through the heat conduction plate 4 to take away the heat, and then returns to the box body 2 through the coil 7. When dissipating heat from the cooling water, the refrigerating surface of the semiconductor refrigeration plate 9 refrigerates and conducts the low temperature to the heat conduction block 10 and contacts and cools the cooling water. Subsequently, the heating surface of the semiconductor refrigeration plate 9 is conducted to the outer wall of the heat dissipation column 13 through the heat dissipation plate 12 to increase the contact area with the air. Subsequently, the cooling fan 14 blows the external air filtered by the dust-proof net 17 towards the outer wall of the heat dissipation column 13 for heat dissipation. Subsequently, the hot air is discharged from the box body 2 through the heat dissipation port 11. When the dust-proof net 17 needs to be cleaned or replaced, simply pull the fixing ring 18 directly off the box body 2. The fixing ring 18 is connected by fitting and adsorbing the magnet 2 to the magnet 15. Subsequently, the dust-proof net 17 can be removed through the installation ring 16 for cleaning. Subsequently, when installing, the fixing ring 18 and the box body 2 are sealed through the sealing ring 20, and the fixing ring 18 and the installation ring 16 are sealed through the sealing ring 21 to prevent dust from being sucked into the box body 2 through the gap when being sucked in by the cooling fan 14, causing pollution.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model.
