Description

Technical Field

[0001] This utility model belongs to the field of cooling technology, and in particular relates to a heat dissipation device for printing and packaging machinery. Background Technology

[0002] Currently, the printing and packaging machinery widely used in the market mainly relies on traditional power transmission methods, such as mechanical transmission devices, to achieve automated printing and packaging operations. These printing and packaging machines typically use fans to form a simple heat exchange system inside the machine, thereby cooling its internal components. However, during the use of traditional printing and packaging machinery, the heat exchange through fans is limited, resulting in poor cooling performance and thus a limited cooling effect. Utility Model Content

[0003] This invention addresses the problem in existing technologies where fans interfere with the normal flow of ink on the printing cylinder surface due to heat exchange inside the printing and packaging machine, resulting in uneven ink distribution and rendering the fan unsuitable for heat dissipation during normal operation. The following technical solution is proposed:

[0004] A heat dissipation device for printing and packaging machinery includes a printing and packaging machine. Both sides of the printing and packaging machine are fitted with outer shells. A heat-conducting block is fixedly connected to the inner wall of the printing and packaging machine, penetrating the inner wall between the printing and packaging machine and the outer shells. A heat-conducting plate is fixedly connected inside the outer shells. The heat-conducting block is fixedly connected to the surface of the heat-conducting plate. A condenser tube is installed on the surface of the heat-conducting plate. A water pump is installed on the surface of the condenser tube and fixedly connected inside the outer shells. A water tank is located at the bottom of the inner shells, below the condenser tube.

[0005] As a preferred embodiment of the above technical solution, one end face of the condenser tube is configured as a water outlet, the other end of the condenser tube is configured as a water inlet, and the water pump is located at the end near the water outlet.

[0006] As a preferred embodiment of the above technical solution, the condenser tube is composed of multiple S-shaped tubes, and the condenser tubes are evenly distributed on the surface of the heat-conducting plate.

[0007] As a preferred embodiment of the above technical solution, a heat-conducting rod is installed inside the water tank, and the number of the heat-conducting rods is set to multiple, with the multiple heat-conducting rods evenly distributed at the bottom of the inside of the water tank.

[0008] As a preferred embodiment of the above technical solution, two exhaust vents are provided inside the single housing. The exhaust vents are located above the water pump. A fan is installed at the top of the back of the housing. A silicone dustproof mesh is fixedly connected to the back of the housing. The silicone dustproof mesh is located below the fan. Both the silicone dustproof mesh and the fan are installed on the surface of the exhaust vents.

[0009] As a preferred embodiment of the above technical solution, a PLC control sensor is embedded in the surface of the outer casing, and the heat-conducting rod, the fan, and the PLC control sensor are all electrically connected.

[0010] The beneficial effects of this utility model are as follows:

[0011] (1) With the assistance of heat-conducting blocks, heat-conducting plates and condenser tubes, the internal temperature of the printing and packaging machine can be effectively reduced. The cooling process of the internal temperature of the printing and packaging machine through the condenser tubes is more stable, thereby improving the operating efficiency of the printing and packaging machine.

[0012] (2) By installing heat-conducting rods inside the water tank and controlling the heat-conducting rods through PLC control sensors, the temperature of the water flow inside the water tank can be controlled, thereby enabling the PLC control sensors to accurately monitor the temperature of the water flow inside the water tank, thus making the cooling process of the printing and packaging machine more stable.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1: This utility model provides a heat dissipation device for printing and packaging machinery, such as... Figures 1 to 6 As shown, the device includes a printing and packaging machine 1, with outer shells 2 installed on both sides of the printing and packaging machine 1. A heat-conducting block 3 is fixedly connected to the inner wall of the printing and packaging machine 1, and the heat-conducting block 3 passes through the inner wall between the printing and packaging machine 1 and the outer shell 2. A heat-conducting plate 4 is fixedly connected inside the outer shell 2, and the heat-conducting block 3 is fixedly connected to the surface of the heat-conducting plate 4. A condenser pipe 5 is installed on the surface of the heat-conducting plate 4, and a water pump 6 is installed on the surface of the condenser pipe 5. The water pump 6 is fixedly connected to the inside of the outer shell 2. A water tank 7 is opened at the bottom of the inside of the outer shell 2, and the water tank 7 is located below the condenser pipe 5.

[0022] like Figures 3 to 6 As shown, one end of the condenser tube 5 is set as the water outlet 14, and the other end of the condenser tube 5 is set as the water inlet 13. The water pump 6 is located at the end near the water outlet 14. By starting the water inlet 13, the water inside the water tank 7 enters the interior of the condenser tube 5 through the water inlet 13. The water inside the condenser tube 5 flows towards the water outlet 14 and carries away the temperature of the surface of the condenser tube 5. Finally, the water inside the condenser tube 5 is extracted by the water pump 6, so that the water inside the water tank 7 forms a heat exchange process inside the condenser tube 5. This allows the printing and packaging machine 1 to be cooled during normal operation, thereby improving the operating efficiency of the printing and packaging machine 1.

[0023] like Figures 3 to 6 As shown, the condenser tube 5 is composed of multiple S-shaped tubes. The condenser tubes 5 are evenly distributed on the surface of the heat-conducting plate 4. The S-shaped condenser tube 5 has a larger contact area with the heat-conducting plate 4, which allows the heat on the surface of the heat-conducting plate 4 to be absorbed more quickly, thereby improving the heat transfer efficiency and accelerating the heat absorption speed of the condenser tube 5 on the surface of the heat-conducting plate 4.

[0024] like Figure 5As shown, a heat-conducting rod 8 is installed inside the water tank 7. The number of heat-conducting rods 8 is set to multiple, and the multiple heat-conducting rods 8 are evenly distributed at the bottom of the inside of the water tank 7. The heat-conducting rods 8 are made of copper. The heat of the water in the water tank 7 is transferred through the heat-conducting rods 8, so that the cold water and hot water mix more slowly when the condenser pipe 5 enters the water tank 7, thereby avoiding uneven water temperature in different areas inside the water tank 7, and making the water temperature inside the water tank 7 more uniform.

[0025] like Figures 2 to 4 As shown, the interior of a single outer casing 2 has two exhaust vents 9, located above the water pump 6. A fan 10 is installed at the top of the back of the outer casing 2, and a silicone dustproof mesh 11 is fixedly connected to the back of the outer casing 2, located below the fan 10. Both the silicone dustproof mesh 11 and the fan 10 are installed on the surface of the exhaust vents 9. A baffle is fixedly connected between the two exhaust vents 9 inside the outer casing 2. When the internal temperature of the outer casing 2 is found to be too high, the fan 10 is started to rotate, and the fan 10 rotates to expel the hot air inside the outer casing 2. The air outside the outer casing 2 enters the interior of the outer casing 2 through the silicone dustproof mesh 11. At this time, an air circulation is formed inside the outer casing 2, which effectively reduces the temperature of the air inside the outer casing 2, thereby avoiding the problem of reduced heat dissipation efficiency of the condenser pipe 5 for the printing and packaging machine 1 due to overheating of the interior of the outer casing 2.

[0026] like Figure 1 and Figure 3 As shown, a PLC control sensor 12 is embedded in the surface of the outer casing 2. The heat conduction rod 8, the fan 10 and the PLC control sensor 12 are all electrically connected. A detection device is fixedly connected inside the outer casing 2. The detection device is electrically connected to the PLC control sensor 12. Through the connection between the PLC control sensor 12 and the heat conduction rod 8 and the fan 10, the PLC control sensor 12 can control the start or stop of the heat conduction rod 8 and the fan 10. This eliminates the need for manual observation of the temperature inside the outer casing 2, thereby preventing the water temperature inside the water tank 7 from becoming too high or too low.

[0027] Working principle: During use, the operator starts the water pump 6, which allows water from the water tank 7 to enter the condenser tube 5 through the inlet 13 and flow towards the outlet 14. The water pump 6 then discharges the water from the condenser tube 5. The product is then placed inside the printing and packaging machine 1. When the temperature inside the printing and packaging machine 1 is too high, the heat-conducting block 3 absorbs the temperature inside the printing and packaging machine 1 and transfers it to the surface of the heat-conducting plate 4. At this time, the water flowing inside the condenser tube 5 draws in the temperature from the surface of the heat-conducting plate 4, and then the water pump 6 discharges this water, thus completing the cooling of the printing and packaging machine 1. This allows the printing and packaging machine 1 to be cooled during normal use, thereby improving its operating efficiency.

[0028] Finally, the PLC controls the sensor 12 to detect the interior of the outer casing 2. When the internal temperature of the outer casing 2 is found to be too high, the fan 10 is started to rotate. The fan 10 rotates to expel the hot air inside the outer casing 2. The air outside the outer casing 2 enters the interior of the outer casing 2 through the silicone dustproof mesh 11. At this time, an air circulation is formed inside the outer casing 2, which effectively reduces the temperature of the air inside the outer casing 2. This avoids the problem of reduced heat dissipation efficiency of the condenser pipe 5 for the printing and packaging machine 1 due to overheating of the interior of the outer casing 2.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
