Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0028] Refer to Figures 1 to 6, this embodiment provides a laser cutting device for diapers, including an operating table 1 and connecting blocks 11 slidably arranged on both sides of the operating table 1. The arrangement of the connecting blocks 11 facilitates the installation of the connecting frame 12 and the motor 21. A connecting frame 12 is provided on the top of the connecting block 11, and the arrangement of the connecting frame 12 facilitates the installation of the second slide rail 25;

[0029] An adjusting component 2, the adjusting component 2 includes a motor 21 arranged on one side of the connecting block 11. A chain 22 is connected to one side of the motor 21. An adjusting frame 24 is provided on the top of the connecting block 11. The adjusting component 2 further includes a first slide rail 23 and a second slide rail 25. The first slide rail 23 is respectively installed on both sides of the operating table 1 and on the connecting frame 12. The second slide rail 25 is arranged on the adjusting frame 24. By starting the motor 21, the chain 22 is driven to move on the first slide rail 23, thereby adjusting the position of the connecting frame 12 on the operating table 1 and the position of the adjusting frame 24 on the connecting frame 12, and at the same time driving the cutting component 3 to move up and down on the adjusting frame 24, so that the height of the cutting component 3 can be adjusted according to the thickness of the diaper raw material, thus ensuring the effect of laser cutting;

[0030] A cutting component 3, the cutting component 3 includes a connecting line 31, and a connecting seat 32 is connected to the end of the connecting line 31. The arrangement of the connecting line 31 effectively limits the movement of the connecting seat 32 and prevents the connecting seat 32 from displacing during movement. A control seat 33 is provided at the bottom of the connecting seat 32, and a control system is arranged inside the control seat 33 to issue accurate laser cutting instructions to the laser head 34. A laser head 34 is provided at the bottom of the control seat 33. A cooling groove 341 is opened inside the laser head 34. The opening of the cooling groove 341 facilitates the entry of cold water, thereby achieving the cooling effect on the laser head 34, being able to cool the laser head 34 in time when it is working at high temperature, thus ensuring the long-term operation of the laser head 34. A nozzle 342 is provided at the bottom of the laser head 34. Through the cooperation between the laser head 34 and the nozzle 342, the diaper raw material on the operating table 1 can be effectively laser cut. A return pipe 35 is arranged on the outer wall of the laser head 34. The return pipe 35 is inserted into the water collecting box 41, and the return pipe 35 is a condensing pipe. The arrangement of the return pipe 35 facilitates pumping the hot water in the cooling groove 341 back to the water collecting box 41, thereby achieving a cold and hot cycle and ensuring that the laser head 34 can be continuously cooled during the cutting operation;

[0031] Cooling component 4, the cooling component 4 includes a water collecting box 41 arranged on the outer wall of the connecting seat 32. Through the setting of the water collecting box 41, a water source is provided for cooling the diaper raw materials and the laser head 34. A water pump 411 is arranged inside the water collecting box 41. Through the setting of the water pump 411, after the water in the cooling tank 341 is heated, it can be timely pumped back into the water collecting box 41, and the heated water is cooled through the condensing pipe to achieve the effect of multiple uses. A first conveying pipe 42 is arranged at the bottom of the water collecting box 41, and a pressing box 44 is arranged at the bottom of the first conveying pipe 42. Through the setting of the pressing box 44, the diaper raw materials can be pressed and fixed after being filled with water inside, and at the same time, it can cool down when the laser head 34 cuts the diaper raw materials, avoiding phenomena such as displacement and deformation of the non-woven fabric during the cutting process, eliminating the generation of burrs from the root, ensuring that the cutting edge is neat and smooth, and significantly improving the appearance quality of the diaper. Fixed frames 45 are symmetrically arranged at the top of the pressing box 44. Through the setting of the fixed frames 45, the pressing box 44 is effectively fixed on both sides of the cutting component 3, so as to ensure that the pressing box 44 moves along with the cutting component 3 to achieve the effect of precise pressing and cooling. A connecting piece 46 is arranged on one side of the pressing box 44. Through the setting of the connecting piece 46, the conveying channel can be opened when the laser head 34 works and heats up to a certain height, facilitating the water source to enter the cooling tank 341.

[0032] It should be noted that the first conveying pipe 42 is a three-way pipe, and an electronic control valve 43 is arranged on the first conveying pipe 42. Through the cooperation between the first conveying pipe 42 and the electronic control valve 43, when the laser head 34 is started, the electronic control valve 43 can be opened, and then the water inside the water collecting box 41 is conveyed to the pressing boxes 44 on both sides of the cutting component 3 through the first conveying pipe 42.

[0033] During use, first start the motor 21 to drive the chain 22 to move on the first slide rail 23 and the second slide rail 25, adjust the positions of the connecting frame 12 and the adjusting frame 24, so as to determine the initial position of the laser head 34, which is convenient for starting the laser cutting work. Secondly, start the laser head 34 to perform laser cutting work through the control seat 33. Then, when the laser head 34 starts to work, the electronic control valve 43 automatically opens, and the water in the water collection box 41 flows into the pressing boxes 44 on both sides of the laser head 34 respectively. By adding water, the weight of the pressing boxes 44 is ensured, achieving the pressing and fixing effect on the raw materials of the diaper. At the same time, due to the injected cold water, the raw materials of the diaper just after laser cutting are quickly cooled, avoiding phenomena such as displacement and deformation of the non-woven fabric during the cutting process, eliminating the generation of burrs from the root, ensuring that the cutting edge is neat and smooth, and significantly improving the appearance quality of the diaper. Then, when the temperature inside the laser head 34 rises to a certain level, the connecting piece 46 opens the conveying channel, facilitating the water source to enter the cooling tank 341 to achieve the cooling effect on the laser head 34. Finally, when the water in the cooling tank 341 heats up, the hot water in the cooling tank 341 is pumped back to the water collection box 41 by the water pump 411, thus achieving a cold and hot cycle and ensuring that the laser head 34 can be continuously cooled during the cutting work.

[0034] Refer to Figure 3 , in an embodiment provided by the present application, the pressing boxes 44 are symmetrically arranged on both sides of the cutting assembly 3. A guiding plate is arranged inside the pressing box 44, and the guiding plate is inclined. Through the arrangement of the guiding plate, it is convenient for the installation of the connecting rope 443 and the balloon 444. Drainage holes 442 are symmetrically opened on the guiding plate. Through the arrangement of the drainage plate 441 and the drainage holes 442, it is convenient for water to enter the bottom of the pressing box 44 faster. A connecting rope 443 is arranged on the guiding plate. Through the arrangement of the connecting rope 443, the balloon 444 can be prevented from floating around in the pressing box 44. The top of the connecting rope 443 is provided with a balloon 444, and the balloon 444 is movably installed inside the first conveying pipe 42. The inside of the balloon 444 is air. Thus, when there is no water source entering, it adheres to the guiding plate. When the water source enters, the balloon 444 floats upward by the buoyancy of the water source and enters the inside of the first conveying pipe 42 to block the water outlet hole 445.

[0035] During use, first, the balloon 444 is located on the surface of the guiding plate under the action of the connecting rope 443. When cold water is conveyed to the pressing plate inside the first conveying pipe 42, secondly, since the density of the balloon 444 is less than that of water, the buoyancy force on the balloon 444 is greater than its gravity, so the balloon 444 floats on the water surface. The water flowing into the pressing box 44 flows into the bottom of the pressing box 44 through the drainage holes 442 on the drainage plate 441, achieving the pressing and fixing and cooling effects on the diaper. Then, when the water level rises to a certain height, the water flows into the second conveying pipe 468. Finally, under the influence of the water level, the balloon 444 floats into the first conveying pipe 42 and blocks the water inlet hole, achieving a short-term water inlet pause effect.

[0036] Referring to Figure 4 , in an embodiment provided by the present application, the connector 46 includes a connecting plate 461 arranged outside the pressing box 44. A placement groove 462 is arranged inside the connecting plate 461. Through the opening of the placement groove 462, it is convenient to install the airbag 464. Third slide rails 463 are symmetrically arranged on both sides of the placement groove 462. Through the opening of the third slide rails 463, it is convenient to adjust the positions of the slider 467 and the adjusting plate 465. An airbag 464 is arranged inside the placement groove 462. The inside of the airbag 464 is nitrogen. One side of the airbag 464 is connected to the laser head 34. Nitrogen is chemically inactive at room temperature and expands when heated and contracts when cooled, and it is relatively safe to use. It can expand after sensing the temperature rise of the laser head 34 and contract after cooling.

[0037] Preferably, an adjusting plate 465 is arranged at the top of the airbag 464, and both ends of the airbag 464 are fixedly connected to the placement groove 462 and the adjusting plate 465 respectively. A conveying hole 466 is opened on the adjusting plate 465. Through the opening of the conveying hole 466 at the back, it is convenient for the water in the second conveying pipe 468 to penetrate through the adjusting plate 465 and enter the cooling groove 341 through the connecting pipe on one side of the laser head 34. Sliders 467 are symmetrically arranged on both sides of the adjusting plate 465. The sliders 467 are slidably installed in the third slide rails 463. Through the arrangement of the sliders 467, the adjusting plate 465 can be driven to move up and down inside the connecting plate 461.

[0038] Furthermore, the connector 46 further includes a second conveying pipe 468. Both ends of the second conveying pipe 468 penetrate through the water outlet hole 445 and the conveying hole 466 respectively. The water in the pressing box 44 is conveyed to the inside of the laser head 34 through the second conveying pipe 468.

[0039] In use, first, when the airbag 464 senses the temperature rise of the laser head 34, the chemical properties of the nitrogen gas inside the airbag 464 become active under the stimulation of high temperature and expand. Limited by the shape of the placement groove 462, the airbag 464 can only move upward, thereby driving the adjustment plate 465 at the top to move upward, making the conveying hole 466 on the adjustment plate 465 fit with the second connecting pipe, facilitating the water in the second conveying pipe 468 to penetrate through the adjustment plate 465 and enter the cooling tank 341 through the connecting pipe on one side of the laser head 34, achieving the cooling effect on the laser head 34.

[0040] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
