Description

Technical Field

[0001] The invention relates to the technical field of laser die-cutting, in particular to a laser die-cutting machine with an intelligent cooling function. Background Art

[0002] Laser die-cutting is a process that uses a high-energy, high-density laser beam to move quickly according to a designed pattern, instantly heating the die-cut material to the vaporization temperature, thereby obtaining continuous or intermittent slits and indentations. Laser die-cutting replaces traditional mechanical die-cutting with a high-energy laser beam, which saves time and effort, is fast and flexible, and has low cost. It is very suitable for die-cutting of self-adhesive labels and packaging materials.

[0003] As we all know, the laser in the laser head is generated by the self-flowing high-voltage excitation pump of the laser tube, but the electro-optical efficiency of the laser tube is low, only about 20%, so the laser tube will generate heat during use. In order to avoid the problem of reduced output power and shortened service life caused by excessive temperature of the laser tube during use, the laser tube is cooled by circulating water during use.

[0004] In the existing die-cutting process, the material is rolled up and moved on the adsorption table, and the laser head cuts the material in the process of movement. In the actual production process, in order to improve production efficiency, the material conveying speed is generally faster under the premise of ensuring cutting quality. Under normal circumstances, it can reach 80m / min. However, due to factors such as material density, thickness, and complexity of the pattern, the cutting speed will be adaptively adjusted, and the temperature of the circulating water is always consistent. If the cutting speed becomes faster, the workload of the laser tube will increase, and the heat will also increase accordingly. It is difficult for the cooling water with a constant temperature to completely cool the laser tube.

[0005] To this end, we propose a laser die-cutting machine with intelligent cooling function. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] See also Figures 1 to 11 The present invention provides a technical solution: a laser die-cutting machine with intelligent cooling function, comprising: a workbench 1, a box 2 and a laser tube 3, the box 2 is fixed at the bottom of the workbench 1, and the laser tube 3 is fixed inside the box 2, a multi-axis moving component is arranged on the top of the workbench 1, and a laser head is installed on the multi-axis moving component, and through holes are evenly opened on the workbench 1, and materials are transported on the workbench 1, and negative pressure can be generated at the through holes to adsorb the materials in the transporting process to ensure the flatness of the cutting position.

[0042] An insulation box 4 is installed inside the box body 2. The function of the insulation box 4 is to suppress heat exchange between the inside and outside of the insulation box 4. When implemented, insulation materials such as glass fiber, fiber mesh, and insulation cotton can be set on the inner wall of the insulation box 4.

[0043] A cooling water storage mechanism 5 is installed inside the thermal insulation box 4. When the cooling water storage mechanism 5 is installed inside the thermal insulation box 4, the thermal insulation box 4 can isolate external heat, thereby reducing the influence of external temperature on the cooling water, so that the temperature fluctuation of the cooling water is always maintained within a small range.

[0044] A water circulation mechanism 6 is installed on the cooling water storage mechanism 5. Specifically, the water circulation mechanism 6 includes a water storage tank 30 fixed in the heat preservation box 4. A first water pump 10 is fixedly installed on the outer wall of the water storage tank 30. A water inlet pipe assembly 11 is installed at the water inlet end of the first water pump 10. The water inlet end of the water inlet pipe assembly 11 is connected to the water storage tank 30. A water outlet pipe 12 is connected to the water outlet end of the first water pump 10. The water outlet end of the water outlet pipe 12 is connected to the water inlet end of the laser tube 3. The water outlet end of the laser tube 3 is connected to a first water return pipe 13. The other end of the first water return pipe 13 is reconnected to the water storage tank 30.

[0045] Therefore, through the above technical solution, when cooling the laser tube 3, the first water pump 10 pumps water into the water storage tank 30 through the water inlet pipe assembly 11, and enters the laser tube 3 through the water outlet pipe 12. When the cooling water flows through the laser tube 3, the laser tube 3 is cooled, and the return water after cooling re-enters the water storage tank 30 through the first water return pipe 13, thereby realizing water circulation.

[0046] A temperature regulating component 7 is installed inside the water tank 30. The temperature regulating component 7 can change the temperature of the cooling water in the water tank 30. In the present embodiment, the temperature regulating component 7 cools the cooling water. The temperature regulating component 7 can be implemented by a semiconductor refrigeration sheet. However, it should be noted that the heating surface of the semiconductor refrigeration sheet needs to be equipped with a heat sink and arranged on the outside of the thermal insulation box 4. The heat is dissipated by a fan. At the same time, a temperature regulating knob 8 is installed on the top of the thermal insulation box 4. The temperature regulating knob 8 is realized by changing the current passing through the semiconductor refrigeration sheet. The cooling temperature of the semiconductor refrigeration sheet is changed by the temperature regulating knob 8. Of course, it can also be achieved by other refrigeration equipment.

[0047] A detection mechanism 9 is installed on one side of the workbench 1. The detection mechanism 9 can detect the conveying speed of the material. At the same time, the detection mechanism 9 can rotate the temperature adjustment knob 8 according to the conveying speed of the material to adjust the refrigeration temperature of the temperature adjustment member 7. Specifically, the detection mechanism 9 includes a detection wheel 14 rotatably installed on the surface of the workbench 1. The end of the detection wheel 14 is driven by a connecting rod 15. When the detection wheel 14 rotates, it can drive the connecting rod 15 to rotate synchronously, that is, firstly, a first pulley 22 is fixedly installed at the end of the detection wheel 14, and a second pulley 23 is fixedly installed at the end of the connecting rod 15. A first transmission belt 24 is installed between the first pulley 22 and the second pulley 23. Therefore, when the detection wheel 14 rotates, the first pulley 22 will rotate synchronously, and the first pulley 22 drives the second pulley 23 to rotate through the first transmission belt 24, thereby realizing the rotation of the connecting rod 15;

[0048] A plurality of telescopic rods 16 are mounted on the outer wall of the connecting rod 15. The plurality of telescopic rods 16 are arranged in a circle with the axis of the connecting rod 15 as the center. The telescopic rod 16 is composed of a sleeve 27, a movable rod 28 and a second spring 29. One end of the sleeve 27 is fixed on the outer wall of the connecting rod 15. The movable rod 28 and the second spring 29 are mounted inside the sleeve 27. The second spring 29 is fixed inside the sleeve 27. The movable rod 28 is slidably mounted inside the sleeve 27. One end of the movable rod 28 is fixed to the end of the second spring 29, and the other end of the movable rod 28 is fixedly installed with a ball 17. An arc-shaped slide rail 18 is slidably installed on the outer side of the ball 17, and an adjusting rod 19 is fixedly installed on the outer side of the slide rail 18. A ring 25 is slidably installed on the outer side of the adjusting rod 19. At the same time, a first spring 26 is sleeved on the outer side of the adjusting rod 19, so that the slide rail 18 can slide on the ring 25 through the adjusting rod 19, that is, an ear plate is fixed on the side of the ring 25, and the adjusting rod 19 is slidably installed in the ear plate on the side of the ring 25. When the slide rail 18 is subjected to force, the adjusting rod 19 can be driven to slide radially along the ring, and the first spring 26 is compressed at the same time. A rack 20 is fixedly installed at the bottom of the adjusting rod 19 at the bottom, and a first gear 21 is meshed on one side of the rack 20. The first gear 21 is fixed on the temperature control knob 8;

[0049] Therefore, through the above technical solution, when the material contacts and rubs against the detection wheel 14 during the conveying process, the detection wheel 14 rotates, and the detection wheel 14 drives the connecting rod 15 to rotate through the first pulley 22, the first transmission belt 24, and the second pulley 23 in turn. When the connecting rod 15 rotates, it drives the telescopic rod 16 to rotate. When the telescopic rod 16 rotates, the internal movable rod 28 and the ball 17 will extend under the action of centrifugal force, and the extended ball 17 continues to squeeze the telescopic slide rail 18, so that the adjusting rod 19 and the rack 20 slide on the ring 25. When the rotation speed of the connecting rod 15 is faster, the centrifugal force on the movable rod 28 and the ball 17 is greater, and the sliding distance of the movable rod 28 is greater. During the sliding process, the rack 20 meshes with the first gear 21, driving the first gear 2 1 is rotated, and when the first gear 21 rotates, the temperature adjustment knob 8 is rotated to adjust the cooling temperature of the temperature adjustment member 7. When the rotation speed is faster, it means that the material conveying speed is faster, the workload of the laser tube 3 in unit time is greater, and the heat generated is more. The greater the rotation speed, the greater the rotation amplitude of the first gear 21. The temperature adjustment knob 8 will adjust the cooling temperature of the temperature adjustment member 7 according to the rotation amplitude of the first gear 21, so that the cooling temperature of the temperature adjustment member 7 is lower. When the cooling temperature is lowered, the cooling water temperature in the water storage tank 30 will gradually decrease. Therefore, when the water circulation mechanism 6 performs water-cooling circulation on the laser tube 3, the cooling effect on the laser tube 3 is better. Therefore, the temperature of the cooling water can be adjusted according to the cutting speed of the material to ensure the cooling effect of the laser tube 3.

[0050] Embodiment 2

[0051] In the above embodiment, the temperature regulating member 7 cools the cooling water, and the cooling temperature can be adjusted. However, when the cooling water cools the laser tube 3, the cooling water will exchange heat with the laser tube 3 at a lower temperature. Under normal circumstances, the working temperature of the laser tube 3 is between 10°C and 30°C, and the temperature of the cooling end of the semiconductor refrigeration plate is at most about 10°C. Therefore, when cooling the laser tube 3, the temperature difference between the laser tube 3 and the cooling water is large, which makes the laser tube 3 prone to condensation. The condensation will cause the laser tube 3 to spark and interfere with the normal operation of the equipment. Therefore, in this embodiment, the temperature regulating member 7 is implemented by a heating tube. The temperature adjustment of the heating tube can also be achieved by changing the resistance wire flowing through the heating tube. The heating tube can gradually heat the cooling water at the initial temperature of the cooling water. For the convenience of explanation, in this embodiment, the temperature in the heat preservation box 4 is set at about 20°C. Of course, if the constant temperature box is kept at a lower temperature, the difficulty of implementation will be greater. Therefore, when the temperature regulating member 7 does not interfere with the cooling water, the water temperature of the cooling water is about 20°C.

[0052] At this time, a plurality of cavities 31 are opened inside the water tank 30, and the interior of the cavity 31 is used to store cooling water, and the height of the plurality of cavities 31 gradually decreases from the inside to the outside, so that the cavities 31 are stepped, and the temperature regulating member 7 is installed in the highest cavity 31. In this embodiment, the number of cavities 31 is set to three, and a drainage pipe 32 is installed between the high and low cavities 31. When the water level in the higher cavity 31 is higher than the drainage pipe 32, it will pass through the lower cavity 31, and a second water pump 33 is fixedly installed on the outer wall of the lowest cavity 31, and the water outlet end of the second water pump 33 is connected to a second return water pipe 34, and the other end of the second return water pipe 34 is connected to the highest cavity 31, that is, when the cooling water flows into the lowest cavity 31, the second water pump 33 will return the water to the highest cavity 31 through the second return water pipe 34.

[0053] The water inlet pipe assembly 11 includes a plurality of vertical pipes 35, each vertical pipe 35 is installed in a corresponding cavity 31, and a connecting pipe 36 is installed on the top of the vertical pipe 35, and the connecting pipe 36 is connected to the water inlet end of the first water pump 10, and a valve 37 is installed on each vertical pipe 35, and an adjusting mechanism 38 is installed at the valve 37, and the adjusting mechanism 38 can open the valves 37 in sequence, and when the valves 37 are opened, they are opened individually, that is, when one of the valves 37 is opened, the other valves 37 are in a closed state;

[0054] Specifically, firstly, a force storage component 39 is installed on the outer wall of the valve stem of the valve 37, and the force storage component 39 can automatically close after the valve 37 is opened, that is, firstly, a coil spring 46 is fixedly installed on the outer wall of the valve stem of the valve 37, and an installation box 45 is installed on the outer side of the coil spring 46, and the installation box 45 is fixed on the corresponding vertical pipe 35;

[0055] Secondly, a second gear 40 is installed at the end of each valve 37, a second transmission belt 41 is provided at the bottom of the second gear 40, rollers 43 are installed at both ends of the second transmission belt 41, a reduction motor 44 is fixedly installed at the end of one of the rollers 43, and a group of gear blocks 42 are fixedly installed on the outer side of the second transmission belt 41, and the gear blocks 42 can mesh with the second gear 40;

[0056] Therefore, through the above technical solution, when the reduction motor 44 rotates, it drives the second transmission belt 41 to rotate, and the second transmission belt 41 drives the tooth block 42 to move during the rotation. When the tooth block 42 contacts the first second gear 40, the first second gear 40 rotates and drives the valve 37 to rotate at the same time, so that the valve 37 can be opened, and the coil spring 46 on the outside of the valve 37 is stored during the rotation of the valve 37. When the second transmission belt 41 continues to move, the tooth block 42 is separated from the first second gear 40. At this time, the tooth block 42 and the second gear 40 are not restricted, and the elastic force of the coil spring 46 is released. The opened valve 37 will reverse under the action of the coil spring 46, thereby closing the valve 37. When the first valve 37 is closed, the tooth block 42 moves to the second valve 37 to open the second valve 37. Therefore, when the reduction motor 44 rotates, the first water pump 10 can pump water from different cavities 31 in turn.

[0057] In summary, when the material is being conveyed, the detection mechanism 9 detects the conveying speed and controls the temperature of the temperature regulating member 7, increasing the temperature in the highest cavity 31 to 30°C, while the temperature of other cavities 31 will gradually decrease due to the obstruction of the middle partition and the heat consumption, for example, to 27°C and 22°C respectively. During the cooling process, the reduction motor 44 operates at the same time, driving the valve 37 on the vertical pipe 35 in the highest cavity 31 to open. At this time, the temperature of the cooling water is 30°C, and the laser tube 3 is cooled by this temperature. After cooling for a period of time, the temperature of the laser tube 3 is maintained at about 30°C, and the second valve 37 is opened, and the first valve 37 and the third valve 37 are opened. The valve 37 is closed, and the laser tube 3 is cooled by cooling water at 27°C. When the laser tube 3 is maintained at 27°C, the laser tube 3 is cooled by cooling water at 22°C. Therefore, the temperature of the cooling water is gradually reduced when cooling the laser tube 3, which can effectively avoid the generation of condensation during cooling. When the material conveying speed increases, the temperature of the temperature regulating member 7 will also increase, the temperature of the cooling water in the highest position cavity 31 increases, and the temperature of the remaining cooling water decreases. At the beginning of cooling, the laser tube 3 is cooled by a higher temperature, and then the temperature of the cooling water decreases again, and finally cooled by the cooling water in the outermost cavity 31.

[0058] It should be added that a blade 47 is rotatably installed at the top of the highest cavity 31, and multiple stirring rods 48 are installed at both ends of the blade 47. The multiple stirring rods 48 are linearly arrayed in the length direction of the blade 47. When the second return water pipe 34 and the first return water pipe 13 transport the returned water to the highest cavity 31, the blade 47 is driven to rotate, and the blade 47 drives the stirring rod 48 to rotate to achieve stirring of the water. It can mix cooling water with different temperatures and ensure the water temperature is consistent as much as possible.
