Description

Technical Field

[0001] This utility model relates to the field of hot stamping machine cooling technology, and in particular to a hot stamping machine cooling device. Background Technology

[0002] Hot stamping machines are widely used in packaging, printing, and labeling industries. They are primarily used to transfer metal foil onto the surface of a substrate through heat and pressure, creating patterns or text with a metallic sheen. Hot stamping not only enhances the appearance and texture of products but also provides practical functions such as anti-counterfeiting and wear resistance, making it highly favored in high-end packaging, bookbinding, and trademark production.

[0003] However, hot stamping machines generate a lot of heat during operation, especially key components such as the hot stamping head. If the heat cannot be dissipated in time, it may cause the equipment to overheat, affecting the hot stamping accuracy or even damaging the equipment.

[0004] Therefore, since the hot stamping head of the hot stamping machine generates a lot of heat during operation, and if this heat cannot be dissipated in time, it may cause the machine to overheat and affect the hot stamping accuracy, a cooling device for the hot stamping machine can be designed to solve the above problems. Utility Model Content

[0005] To address the issue that if the large amount of heat generated on the hot stamping head during the operation of the hot stamping machine cannot be dissipated in time, it may cause the equipment to overheat and affect the accuracy of hot stamping.

[0006] The technical solution of this utility model is as follows: a cooling device for a hot stamping machine, including a water tank; and a capillary filling plate. An ultrasonic transducer is installed inside the water tank, an air pump is installed on one side of the water tank, an air inlet pipe is installed at the upper end of the air pump, a hot stamping head is installed at the front end of the air inlet pipe, a double-hole U-shaped groove is opened inside the hot stamping head, an exhaust pipe is provided on one side of the air inlet pipe, a multi-segment heat dissipation pipe is connected to the lower end of the exhaust pipe, a drain pipe is fixedly connected to the lower end of the multi-segment heat dissipation pipe, a capillary filling plate is fixedly connected inside the multi-segment heat dissipation pipe, a capillary filling column is fixedly connected inside the drain pipe, and six heat dissipation grooves are opened on the inner wall of the multi-segment heat dissipation pipe.

[0007] Preferably, the ultrasonic transducer breaks the cooling water stored in the water tank into water mist through high-frequency vibration. An air pump then delivers air and water mist into the air inlet pipe, the double-hole U-shaped channel, the exhaust pipe, and the multi-section heat dissipation pipe. As the air and water mist flow within the double-hole U-shaped channel, they absorb excess heat from the hot-stamping head. The double-hole design of the U-shaped channel increases the heat exchange area. Subsequently, as the air flows through the multi-section heat dissipation pipe, the water mist continues to absorb heat from the air. Furthermore, when the water mist comes into contact with the capillary filling plate, it is absorbed by the capillary filling plate and then absorbed through the capillary... The fine-pore filling column slowly flows downwards back to the water tank. The multi-segment vertical and 45-degree lifting mechanism of the multi-segment heat dissipation tubes not only increases the length of the multi-segment heat dissipation tubes, but also makes it easier for the water mist to be absorbed by the capillary filling plate as it moves through the multi-segment heat dissipation tubes. In addition, the heat dissipation groove increases the heat exchange area between the air in the multi-segment heat dissipation tubes and the water in the capillary filling plate and the outside. Moreover, the water in the capillary filling plate has a slower flow rate and will undergo a longer cooling time. During the cooling process, the water will also continue to cool the air that passes by.

[0008] Preferably, the air intake pipe and exhaust pipe are connected to the double-hole U-shaped groove, the capillary filling plate and the capillary filling column are fixedly connected, and the upper end face of the water tank is connected and connected to the multi-section heat dissipation pipe and the drain pipe.

[0009] Preferably, a resistance heater is provided at the upper end of the double-hole U-shaped groove. The resistance heater is installed inside the hot stamping head, and a heat insulation pad is fixed to the upper surface of the hot stamping head.

[0010] Preferably, a hydraulic cylinder is fixed to the upper end of the heat insulation pad, and the outside of the hydraulic cylinder is fixed to the inside of the frame. The front ends of both sides of the frame are rotatably connected to pad rollers.

[0011] Preferably, each pad roller is provided with a rotating shaft at its upper end, the rotating shaft is rotatably connected to the frame, and an insert is slidably connected to the outside of the rotating shaft.

[0012] Preferably, two servo motors are installed at the rear of the frame, the servo motors are connected to the rotating shaft, and a belt conveyor is installed at the lower end of the hot stamping head.

[0013] Preferably, the lower end of the frame is fixedly connected to the rear end face of the belt conveyor, the lower end of the belt conveyor is fixedly connected to a base, and a water inlet is opened on one side of the upper end face of the water tank.

[0014] The beneficial effects of this utility model are:

[0015] By incorporating a capillary-filled plate and heat dissipation channels, the ultrasonic transducer breaks down the cooling water stored in the tank into a mist through high-frequency vibration. An air pump then delivers the air and water mist into the air inlet pipe, the double-hole U-shaped channel, the exhaust pipe, and the multi-segment heat dissipation pipes. As the air and water mist flow within the double-hole U-shaped channel, they absorb excess heat from the hot-stamping head. The double-hole design of the U-shaped channel also increases the heat exchange area. Subsequently, as the air flows through the multi-segment heat dissipation pipes, the water mist continues to absorb heat from the air. Furthermore, the water mist is absorbed by the capillary-filled plate upon contact with it and slowly flows downwards back into the water through the capillary-filled column. The multi-segment vertical and 45-degree lifting mechanism of the multi-segment heat dissipation tubes not only increases the length of the multi-segment heat dissipation tubes, but also makes it easier for water mist to be absorbed by the capillary filling plate as it moves through the multi-segment heat dissipation tubes. In addition, the heat dissipation groove increases the heat exchange area between the air in the multi-segment heat dissipation tubes and the water in the capillary filling plate and the outside. Moreover, the water in the capillary filling plate has a slower flow rate and will undergo a longer cooling time. During the cooling process, the water will also continue to cool the air passing by. Thus, the hot stamping head is cooled by a combination of water cooling and air cooling to prevent the equipment from overheating and ensure the accuracy of hot stamping. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-7 This utility model provides an embodiment of a hot stamping machine cooling device, including a water tank 1 and a capillary filling plate 10. An ultrasonic transducer 2 is installed inside the water tank 1. An air pump 3 is installed on one side of the water tank 1. An air inlet pipe 4 is installed at the upper end of the air pump 3. A hot stamping head 5 is installed at the front end of the air inlet pipe 4. A double-hole U-shaped groove 6 is opened inside the hot stamping head 5. An exhaust pipe 7 is provided on one side of the air inlet pipe 4. A multi-segment heat dissipation pipe 8 is connected to the lower end of the exhaust pipe 7. A drain pipe 9 is fixedly connected to the lower end of the multi-segment heat dissipation pipe 8. The capillary filling plate 10 is fixedly connected inside the multi-segment heat dissipation pipe 8. A capillary filling column 11 is fixedly connected inside the drain pipe 9. Six heat dissipation grooves 12 are opened on the inner wall of the multi-segment heat dissipation pipe 8. The ultrasonic transducer 2 breaks the cooling water stored in the water tank 1 into water mist through high-frequency vibration. The air pump 3 then sends air and water mist into the air inlet pipe 4, the double-hole U-shaped groove 6, the exhaust pipe 7, and the multi-segment heat dissipation pipe 8. During the flow of air within the double-hole U-shaped channel 6, excess heat from the hot stamping head 5 is absorbed. The double-hole channel 6 increases the heat exchange area. Subsequently, as the air flows within the multi-segment heat dissipation tube 8, the water mist continues to absorb heat from the air. The water mist is absorbed by the capillary filling plate 10 upon contact with it and slowly flows back to the water tank 1 through the capillary filling column 11. The multi-segment vertical and 45-degree lifting mechanism of the multi-segment heat dissipation tube 8 not only increases the length of the multi-segment heat dissipation tube 8 but also makes it easier for the water mist to be contacted and absorbed by the capillary filling plate 10 during the wave-like movement within the multi-segment heat dissipation tube 8. In addition, the heat dissipation groove 12 increases the heat exchange area between the air within the multi-segment heat dissipation tube 8, the water within the capillary filling plate 10, and the outside environment. Furthermore, the water flow rate within the capillary filling plate 10 is relatively slow, resulting in a longer cooling time. During the cooling process, the water also continues to cool the air that passes by.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7The intake pipe 4 and exhaust pipe 7 are connected to the double-hole U-shaped groove 6. The capillary filling plate 10 and the capillary filling column 11 are fixedly connected. The upper end face of the water tank 1 is connected to and connected to the multi-section heat dissipation pipe 8 and the drain pipe 9. The upper end of the double-hole U-shaped groove 6 is provided with a resistance heater 13. The resistance heater 13 is installed inside the hot stamping head 5. The upper end face of the hot stamping head 5 is fixedly connected with a heat insulation pad 14. The resistance heater 13 is used to heat the hot stamping head 5. The upper end face of the heat insulation pad 14 is fixedly connected with a hydraulic cylinder 15. The outside of the hydraulic cylinder 15 is fixedly connected to the inside of the frame 16. The front ends of both sides of the frame 16 are rotatably connected with pad rollers 17. The heat insulation pad 14 is used to prevent the heat of the resistance heater 13 from being conducted to the hydraulic cylinder 15.

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In this embodiment, each pad roller 17 has a rotating shaft 18 at its upper end, which is rotatably connected to the frame 16. Inserts 19 are slidably connected to the outer side of the rotating shaft 18. The two ends of the hot stamping material are wound around the two inserts 19 on both sides, and the material is placed on the lower ends of the pad roller 17 and the hot stamping head 5. Then, the servo motor 20 controls the forward and reverse rotation of the rotating shaft 18 to adjust the tension of the material and control its rotation. Two servo motors 20 are installed at the rear end of the frame 16. The servo motors 20 are connected to the rotating shaft 17. The shaft 18 is connected, and the lower end of the hot stamping head 5 is equipped with a belt conveyor 21. The material to be hot stamped is placed on the upper end of the belt conveyor 21, and the material to be hot stamped and the hot stamping material are moved at the same speed by the belt conveyor 21. Then, the hot stamping head 5 is pressed down by the hydraulic cylinder 15 to press the hot stamping material onto the material to be hot stamped, thus completing the hot stamping. The lower end of the frame 16 is fixedly connected to the rear end face of the belt conveyor 21. The lower end of the belt conveyor 21 is fixedly connected to the base 22. A water inlet 23 is opened on one side of the upper end face of the water tank 1.

[0028] In use, the two ends of the hot stamping material are wrapped around the two inserts 19 on both sides, and the material is placed on the pad roller 17 and the bottom of the hot stamping head 5. Then, the tension of the material is adjusted and the rotation of the material is controlled by the forward and reverse rotation of the rotating shaft 18 by the servo motor 20. After the hot stamping head 5 is heated by the resistance heater 13, the material to be hot stamped is placed on the upper end of the belt conveyor 21, and the material to be hot stamped and the hot stamping material are moved at the same speed by the belt conveyor 21. Then, the hot stamping head 5 is pressed down by the hydraulic cylinder 15 to press the hot stamping material onto the material to be hot stamped, thus completing the hot stamping.

[0029] Simultaneously, the ultrasonic transducer 2 breaks the cooling water stored in the water tank 1 into water mist through high-frequency vibration. The air pump 3 then sends air and water mist into the air inlet pipe 4, the double-hole U-shaped channel 6, the exhaust pipe 7, and the multi-section heat dissipation pipe 8. As the air and water mist flow within the double-hole U-shaped channel 6, they absorb excess heat from the hot-stamping head 5. The double-hole design of the double-hole U-shaped channel 6 increases the heat exchange area. Subsequently, as the air flows within the multi-section heat dissipation pipe 8, the water mist continues to absorb heat from the air. Furthermore, when the water mist comes into contact with the capillary filling plate 10, it is absorbed by the capillary filling plate 10 and then absorbed through the capillary tube. The fine-pore filling column 11 slowly flows downward back to the water tank 1. The multi-segment vertical and 45-degree lifting mechanism of the multi-segment heat dissipation pipe 8 can not only increase the length of the multi-segment heat dissipation pipe 8, but also make it easier for the water mist to be contacted and absorbed by the capillary filling plate 10 during the wave-like movement in the multi-segment heat dissipation pipe 8. In addition, the heat dissipation groove 12 can increase the heat exchange area between the air in the multi-segment heat dissipation pipe 8 and the water in the capillary filling plate 10 and the outside. Moreover, the water in the capillary filling plate 10 has a slower flow rate and will undergo a longer cooling time. During the cooling process, the water will also continue to cool the air that passes by.

[0030] Through the above steps, by setting the capillary filling plate 10 and the heat dissipation groove 12, the ultrasonic transducer 2 can break the cooling water stored in the water tank 1 into water mist through high-frequency vibration. The air pump 3 then sends air and water mist into the air inlet pipe 4, the double-hole U-shaped groove 6, the exhaust pipe 7, and the multi-segment heat dissipation pipe 8. As the air and water mist flow in the double-hole U-shaped groove 6, they absorb excess heat from the hot stamping head 5. The double-hole U-shaped groove 6 can increase the heat exchange area. Subsequently, as the air flows in the multi-segment heat dissipation pipe 8, the water mist will continue to absorb heat from the air. The water mist will be absorbed by the capillary filling plate 10 when it comes into contact with it, and then slowly absorbed by the capillary filling column 11. The water slowly flows back to the water tank 1. The multi-segment vertical and 45-degree lifting mechanism of the multi-segment heat dissipation pipe 8 not only increases the length of the multi-segment heat dissipation pipe 8, but also makes it easier for the water mist to be absorbed by the capillary filling plate 10 during the wave-like movement within the multi-segment heat dissipation pipe 8. In addition, the heat dissipation groove 12 increases the heat exchange area between the air in the multi-segment heat dissipation pipe 8 and the water in the capillary filling plate 10 and the outside. Moreover, the water in the capillary filling plate 10 has a slower flow rate and will undergo a longer cooling time. During the cooling process, the water will also continue to cool the air that passes by. Thus, the hot stamping head 5 is cooled by a combination of water cooling and air cooling to prevent the equipment from overheating and ensure the hot stamping accuracy.
