[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When the strip laser slitting equipment is in use, the fan generates suction on the air box through the air duct, so that after the air is filtered by the filter screen, it is sucked into the inner side of the air box through the air duct and the air outlet. After the air is cooled by the water mist, and then after the water droplets adhere to the nylon net, the cold air flows upward on the outer side of the cold pipe. The water pump pumps the coolant of the laser cutting instrument to the inner side of the branch pipe. The coolant is shunted through the branch pipe to the inner sides of multiple cold pipes, and the cooling work is carried out through the cold pipes. Then, after converging through the branch pipe, it enters the inner side of the laser cutting instrument through the connecting pipe to carry out the cooling work on the laser cutting instrument, ensuring the working safety of the laser cutting instrument. If the temperature of the coolant in the branch pipe is relatively high, the air in the cavity expands and pushes the piston upward. The piston contacts the electrode, and the number of solenoid valves is controlled by the electrode according to the temperature of the coolant, thereby adjusting the spray amount of the water, further adjusting the cooling efficiency of the air, and further adjusting the cooling rate of the coolant to ensure the working safety of the laser cutting instrument. When using the piston to press the button, the button adjusts the power of the fourth motor through the frequency converter to ensure the pushing pressure on the water, and thus ensure the atomization effect. If the pushing pressure of the fourth motor on the water through the screw plate is too large, the water pressure opens the pressure relief valve and flows through the conduit to the inner side of the return pipe, preventing the water from directly pushing open the pressure valve and flowing outwards, avoiding the waste of water resources. The cooling and temperature reduction work is carried out by the evaporation of the water, which not only ensures the heat dissipation safety of the laser cutting instrument but also reduces the energy consumption of the heat dissipation work.

[0016] 2. When the strip laser slitting equipment is in use, the first motor and the second motor respectively drive the strip to be conveyed to the right inside the box body through the roller and the conveyor until the right end of the strip moves to the bottom of the length measuring instrument, so that the distance between the right end of the strip and the laser cutting instrument is equal to the required length. Then, the bottom of the length measuring instrument is pushed upward by the strip, and the trigger switch is enabled to turn on the laser cutting instrument for cutting work. The penetrated laser enters the inner side of the water tank, and after being scattered by the water and the prism, the density of the laser is reduced. The laser is absorbed by the iron sheet, and then the iron sheet is cooled by the water, thereby effectively absorbing the energy of the laser penetrated by the cutting work and preventing the laser from damaging the bottom of the equipment and ensuring the safety of the equipment.

[0017] 3. When the strip laser slitting equipment is in use, the debris generated during the cutting operation and the impurities carried by the strip fall to the inner side of the water tank. The motor four drives the screw plate to rotate inside the sleeve, causing the sleeve to carry the water and impurities in the water tank into the inner side of the sleeve. After being filtered by the filter cartridge, the water enters the spray pipe through the ferrule and is atomized and sprayed inside the air box through the nozzle. Using the airflow in the air box, the water mist quickly evaporates, absorbing a large amount of heat, thereby reducing the heat of the water. After the water falls to the top of the partition plate, it flows back to the inner side of the water tank through the return pipe, effectively reducing the water temperature in the water tank and improving the purity of the water at the same time. It avoids the top water being directly heated and vaporized by the laser due to the turbidity of the water, reduces the generation of water vapor in the water tank, and further avoids the circuit in the box from malfunctioning due to high humidity, ensuring the circuit safety of the equipment. The impurities are pushed upward by the screw plate inside the filter cartridge. As the impurities increase, the thrust of the screw plate on the impurities increases, causing the impurities to push open the pressure valve and be discharged outward through the discharge pipe, ensuring the filtering efficiency of the filter cartridge and facilitating the separation of impurities.

[0027] In this embodiment, a ferrule 25 is welded to the top end of the sleeve 21, a filter cartridge 26 is welded to the inner side of the ferrule 25, the top end of the screw plate 24 is stuck on the inner wall of the filter cartridge 26, a discharge pipe 27 is welded to the top of the ferrule 25, a pressure valve is installed inside the discharge pipe 27, the pressure valve is communicated with the top of the filter cartridge 26, a spray pipe 28 is installed on the ferrule 25, the spray pipe 28 extends to the inside of the box body 1, a spray head 29 is installed at the bottom of the spray pipe 28 through bolts, an electromagnetic valve 30 is installed on the spray head 29, a filter screen 31 is welded to the bottom of the air box 14, a partition plate 32 is welded to the inner wall of the bottom of the air box 14, an air duct 33 is welded to the top of the partition plate 32, an air outlet 34 is opened at the top end of the air duct 33, the air outlets 34 are evenly distributed on the top of the air duct 33, the bottom of the partition plate 32 is communicated with the inside of the air box 14 through the air duct 33 and the air outlet 34, a return pipe 22 is welded to the bottom of the air box 14, one end of the return pipe 22 is communicated with the top of the partition plate 32, and the other end of the return pipe 22 is communicated with the water tank 7. A frequency converter 36 is installed on the motor four 23, the button 41 is connected to the frequency converter 36 through an electric wire, the frequency converter 36 is connected to the motor four 23 through an electric wire, and the electrode 40 is connected to the electromagnetic valve 30 through an electric wire. During use, the debris generated during the cutting operation and the impurities carried by the rubber strip fall into the inside of the water tank 7. The motor four 23 drives the screw plate 24 to rotate inside the sleeve 21, so that the sleeve 21 carries the water in the water tank 7 with impurities into the inside of the sleeve 21. After being filtered by the filter cartridge 26, the water enters the spray pipe 28 through the ferrule 25, and then is atomized and sprayed inside the air box 14 through the spray head 29. Using the air flow inside the air box 14, the water mist quickly evaporates, absorbs a large amount of heat, thereby reducing the heat of the water. After the water falls to the top of the partition plate 32, it then flows back to the inside of the water tank 7 through the return pipe 22, thereby effectively reducing the water temperature in the water tank 7 and at the same time improving the purity of the water, avoiding the water at the top being directly heated and vaporized by the laser due to the turbidity of the water, reducing the generation of water vapor in the water tank 7, and further avoiding the failure of the circuit inside the box body 1 due to high humidity, ensuring the circuit safety of the equipment. The impurities are pushed upward by the screw plate 24 inside the filter cartridge 26. As the impurities increase, the pushing force of the screw plate 24 on the impurities increases, causing the impurities to push open the pressure valve and be discharged outward through the discharge pipe 27, ensuring the filtering efficiency of the filter cartridge 26 and facilitating the separation of the impurities.

[0028] In this embodiment, the bellows 14 is installed outside the box body 1. The laser cutting instrument 2 is a liquid-cooled laser cutting instrument. The water pump 15 is installed on the outer side of the bellows 14 by bolts. The branch pipe 16 is welded on the outer side of the bellows 14. One side of the water pump 15 is communicated with the top of the laser cutting instrument 2. The top of the water pump 15 is communicated with the branch pipe 16. One end of the cold pipe 17 is communicated with the branch pipe 16. The other end of the cold pipe 17 is coiled inside the bellows 14 and is communicated with one side of the branch pipe 16.

A pressure relief valve 44 is installed on the conduit 43. A nylon net 35 is adhered to the inner wall of the bellows 14. The nylon net 35 is installed on the top of the spray pipe 28. A cavity 37 is welded on the top of the branch pipe 16. A sliding sleeve 38 is welded on the top of the cavity 37. The sliding sleeve 38 is communicated with the cavity 37. A piston 39 is clamped inside the sliding sleeve 38. An electrode 40 is welded on the inner wall of the sliding sleeve 38. A button 41 is arranged inside the sliding sleeve 38. The top of the button 41 is connected to the inner wall of the sliding sleeve 38 through a spring 42. During use, the fan 18 generates suction on the bellows 14 through the air cylinder 19, so that after the air is filtered by the filter screen 31, it is sucked into the inside of the bellows 14 through the air pipe 33 and the air outlet 34. After the air is cooled by water mist, and then after passing through the attached water droplets of the nylon net 35, the cold air flows upward on the outside of the cold pipe 17. The water pump 15 pumps the coolant of the laser cutting instrument 2 into the inside of the branch pipe 16. The coolant is split into the inside of multiple cold pipes 17 through the branch pipe 16, and cooling work is carried out through the cold pipes 17. After converging through the branch pipe 16, it enters the inside of the laser cutting instrument 2 through the connecting pipe 20 to carry out cooling work on the laser cutting instrument 2, ensuring the working safety of the laser cutting instrument 2. If the temperature of the coolant in the branch pipe 16 is relatively high, the air in the cavity 37 expands and pushes the piston 39 upward. The piston 39 contacts the electrode 40, and the number of solenoid valves 30 is controlled by the electrode 40 according to the temperature of the coolant, thereby adjusting the spray amount of water, thereby adjusting the cooling efficiency of the air, and thereby adjusting the cooling rate of the coolant to ensure the working safety of the laser cutting instrument 2. When using the piston 39 to squeeze the button 41, the button 41 adjusts the power of the motor four 23 through the frequency converter 36 to ensure the pushing pressure on the water, and thereby ensure the atomization effect. If the pushing pressure of the motor four 23 on the water through the screw plate 24 is too large, the water pressure opens the pressure relief valve 44 and flows into the inside of the return pipe 22 through the conduit 43, preventing the water from directly pushing open the pressure valve and flowing outwards, avoiding waste of water resources, and using the evaporation of water for cooling work, which not only ensures the heat dissipation safety of the laser cutting instrument 2 but also reduces the energy consumption of the heat dissipation work.

[0029] The strip laser slitting equipment provides electrical energy for all electrical equipment through an external power supply. During use, the first motor 3 and the second motor 5 drive the strip to move rightward inside the box body 1 through the roller 4 and the conveyor 6 respectively until the right end of the strip moves to the bottom of the length measuring instrument 13, making the distance between the right end of the strip and the laser cutting instrument 2 equal to the required length. As a result, the bottom of the length measuring instrument 13 is pushed upward by the strip, and the trigger switch is enabled to turn on the laser cutting instrument 2 for cutting work. The penetrating laser enters the inside of the water tank 7, and after being scattered by the water and the prism 8, the density of the laser is reduced. The laser is absorbed by the iron sheet 9, and then the iron sheet 9 is cooled by the water, effectively absorbing the energy of the laser penetrated during the cutting work, avoiding damage to the bottom of the equipment by the laser, ensuring the safety of the equipment. The debris generated during the cutting work and the impurities carried by the strip fall into the inside of the water tank 7. The fourth motor 23 drives the screw plate 24 to rotate inside the sleeve 21, causing the sleeve 21 to carry the water and impurities in the water tank 7 into the inside of the sleeve 21. After being filtered by the filter cartridge 26, the water enters the spray pipe 28 through the ferrule 25 and is atomized and sprayed inside the air box 14 through the nozzle 29. Utilizing the airflow in the air box 14, the water mist quickly evaporates, absorbing a large amount of heat, thereby reducing the heat of the water. After the water falls to the top of the partition plate 32, it flows back into the inside of the water tank 7 through the return pipe 22, effectively reducing the water temperature in the water tank 7 and at the same time improving the purity of the water, avoiding the direct heating and vaporization of the water at the top due to the turbidity of the water, reducing the generation of water vapor in the water tank 7, and thus avoiding the failure of the circuit inside the box body 1 due to high humidity, ensuring the circuit safety of the equipment. The impurities are pushed upward by the screw plate 24 inside the filter cartridge 26. As the impurities increase, the thrust of the screw plate 24 on the impurities increases, causing the impurities to push open the pressure valve and be discharged outward through the discharge pipe 27, ensuring the filtering efficiency of the filter cartridge 26 and facilitating the separation of impurities. The fan 18 generates suction on the air box 14 through the air duct 19, causing the air to be filtered by the filter screen 31 and then inhaled into the inside of the air box 14 through the air duct 33 and the air outlet 34. After the air is cooled by the water mist and then passes through the nylon mesh 35 with attached water droplets, the cold air flows upward outside the cold pipe 17. The water pump 15 pumps the coolant of the laser cutting instrument 2 into the inside of the branch pipe 16. The coolant is distributed into the inside of multiple cold pipes 17 through the branch pipe 16 and undergoes cooling work through the cold pipes 17. After converging through the branch pipe 16, it enters the inside of the laser cutting instrument 2 through the connecting pipe 20 to perform cooling work on the laser cutting instrument 2, ensuring the working safety of the laser cutting instrument 2. When the temperature of the coolant in the branch pipe 16 is relatively high, the air in the cavity 37 expands and pushes the piston 39 upward. The piston 39 contacts the electrode 40, and the number of solenoid valves 30 is controlled by the electrode 40 according to the temperature of the coolant, thereby adjusting the spraying amount of the water, further adjusting the cooling efficiency of the air, and further adjusting the cooling rate of the coolant to ensure the working safety of the laser cutting instrument 2.When the piston 39 is used to squeeze the button 41, the button 41 adjusts the power of the fourth motor 23 through the frequency converter 36 to ensure the pushing pressure of the moisture, thereby ensuring the atomization effect. If the pushing pressure of the moisture by the fourth motor 23 through the screw plate 24 is too large, the water pressure opens the pressure relief valve 44 and flows through the conduit 43 to the inside of the return pipe 22, preventing the moisture from directly pushing open the pressure valve and flowing outwards, avoiding waste of water resources, and using the evaporation of the moisture for cooling work, which not only ensures the heat dissipation safety of the laser cutting instrument 2 but also reduces the energy consumption of the heat dissipation work.
