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

[0015] 1. In operation, this laser cutting equipment for adhesive strips uses a fan to create suction in the air box via a duct. Air is filtered through a screen and then drawn into the air box through the duct and vents. The air is cooled by water mist, and after passing through a nylon mesh with water droplets, the cool air flows upwards on the outside of the cooling pipes. A water pump delivers coolant from the laser cutter to the inside of the distribution pipes. The coolant is then distributed to the inside of multiple cooling pipes for further cooling. After merging through the distribution pipes, the coolant enters the laser cutter through a connecting pipe, further cooling the laser cutter and ensuring its safe operation. If the coolant temperature in the distribution pipes is high, the air inside the cavity expands, pushing the piston upwards. The piston is pushed to contact the electrode, and the number of solenoid valves opened by the electrode is controlled according to the temperature of the coolant, thereby adjusting the amount of water sprayed, the cooling efficiency of the air, and the cooling rate of the coolant to ensure the safe operation of the laser cutter. When the piston is pressed, the button adjusts the power of motor four through the frequency converter to ensure the pushing pressure of the water and thus ensure the atomization effect. If the pushing pressure of motor four on the water through the screw plate is too high, the water pressure opens the pressure relief valve and flows to the inside of the return pipe through the conduit, preventing the water from directly pushing open the pressure valve and flowing outward, thus avoiding the waste of water resources. The evaporation of water is used for cooling, which not only ensures the heat dissipation safety of the laser cutter but also reduces the energy consumption of the heat dissipation work.

[0016] 2. In use, the laser slitting equipment for adhesive strips uses motors 1 and 2 to drive the adhesive strip to the right inside the housing via rollers and a conveyor, until the right end of the adhesive strip reaches the bottom of the length measuring device. This ensures that the distance between the right end of the adhesive strip and the laser cutter is equal to the required length. Consequently, the bottom of the length measuring device is pushed upwards by the adhesive strip, triggering the switch to turn on the laser cutter for cutting. The penetrating laser enters the inside of the water tank, where it is scattered by water and a prism, reducing its density. The laser is absorbed by an iron sheet, which is then cooled by water. This effectively absorbs the energy of the laser penetrating the device during cutting, preventing damage to the bottom and ensuring the safety of the equipment.

[0017] 3. In the laser cutting equipment for adhesive strips, the debris generated during cutting and impurities carried by the adhesive strips fall into the inner side of the water tank. Motor 4 drives the screw plate to rotate inside the sleeve, causing the sleeve to draw water and impurities from the water tank into the inner side of the sleeve. After being filtered by the filter cartridge, the water enters the nozzle through the ferrule and is then atomized and sprayed out through the nozzle inside the air box. The airflow inside the air box causes the water mist to evaporate rapidly, absorbing a large amount of heat and thus reducing the heat of the water. After falling to the top of the baffle, the water flows back through the return pipe. The water is directed to the inside of the tank, effectively reducing the water temperature and increasing the purity of the water. This prevents the water from becoming turbid and being directly heated and vaporized by the laser, reducing the generation of water vapor in the tank. This also prevents circuit malfunctions due to high humidity, ensuring the safety of the equipment's circuitry. Impurities are pushed upwards by the screw plate inside the filter cartridge. As the amount of impurities increases, the screw plate's thrust on the impurities increases, causing the impurities to open the pressure valve and be discharged outwards through the drain pipe. This ensures the filtration efficiency of the filter cartridge and facilitates the separation of impurities. Attached Figure Description

The conveyor 6 is mounted on the inner side of the other end of the housing 1. The motor 5 is mounted on the outer side of the housing 1 via bolts. The drive shaft of the conveyor 6 passes through the inner wall of the housing 1 and is keyed to the output shaft of the motor 5. The laser cutter 2 is mounted via bolts. The laser cutter 2 is installed on the top of the housing 1, with its bottom extending to the inside of the housing 1. The motor 3 11 is bolted to the other end of the housing 1. A lead screw 12 is mounted on the output shaft of the motor 3 11. The length calibrator 13 is threaded onto the outer side of the lead screw 12, with its top extending to the top of the housing 1.

A trigger switch is installed on the inner side of the upper sleeve, and the trigger switch is connected to the laser cutter 2 via a wire. The water tank 7 is welded to the bottom of the housing 1. The water tank 7 is located at the bottom of the laser cutter 2. The two ends of the prism 8 are bolted to the inner wall of the water tank 7. An iron plate 9 is installed inside the water tank 7, located at the bottom of the prism 8. The water tank 7 is filled with water, and both the prism 8 and the iron plate 9 are located inside the water. A water pipe 10 is installed on the water tank 7. The sleeve 21 is bolted to the outside of the air box 14, and its bottom end is connected to the water tank 7. The motor 23 is bolted to the bottom end of the sleeve 21. A screw plate 24 is secured inside the sleeve 21, and its bottom end is keyed to the output shaft of the motor 23. During use, the motor 23 and the air box 10... Machine 2 5 drives the rubber strip to the right inside the housing 1 via the rotating roller 4 and the conveyor 6 until the right end of the rubber strip moves to the bottom of the length measuring instrument 13, so that the distance between the right end of the rubber strip and the laser cutter 2 is equal to the required length. This causes the bottom of the length measuring instrument 13 to be pushed upward by the rubber strip, and triggers the switch to turn on the laser cutter 2 to start the cutting work. The penetrating laser enters the inside of the water tank 7. 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 the water is used to cool the iron sheet 9, thereby effectively absorbing the energy of the laser penetrating during the cutting work, avoiding damage to the bottom of the equipment by the laser, and ensuring the safety of the equipment.

[0027] In this embodiment, a retaining sleeve 25 is welded to the top of the sleeve 21, and a filter cartridge 26 is welded to the inner side of the retaining sleeve 25. The top of the screw plate 24 is clamped onto the inner wall of the filter cartridge 26. A pipe 27 is welded to the top of the retaining sleeve 25, and a pressure valve is installed on the inner side of the pipe 27. The pressure valve is connected to the top of the filter cartridge 26. A spray pipe 28 is installed on the retaining sleeve 25, and the spray pipe 28 extends to the inner side of the housing 1. A nozzle 29 is bolted to the bottom of the spray pipe 28, and a solenoid valve 30 is installed on the nozzle 29. A filter screen 31 is welded to the bottom of the air box 14. A partition 32 is welded to the inner wall of the air box 14. A duct 33 is welded to the top of the partition 32, and air vents 34 are evenly distributed at the top of the duct 33. The bottom of the partition 32 is connected to the inner side of the air box 14 via the duct 33 and air vents 34. A return pipe 22 is welded to the bottom of the air box 14. One end of the return pipe 22 is connected to the top of the partition 32, and the other end is connected to the water tank 7. A frequency converter 36 is installed on the motor 43. The button 41 is connected to the frequency converter 36 via wires. The frequency converter 36 is connected to the motor 43 via wires. 23 Connection: The electrode 40 is connected to the solenoid valve 30 via a wire. During use, the debris generated during cutting and the impurities carried by the adhesive strip fall into the inner side of the water tank 7. The motor 23 drives the screw plate 24 to rotate inside the sleeve 21, causing the sleeve 21 to draw water and impurities from the water tank 7 into its inner side. After being filtered by the filter cartridge 26, the water enters the nozzle 28 through the retainer 25, and then is atomized and sprayed out through the nozzle 29 inside the air box 14. The airflow inside the air box 14 causes the water mist to evaporate quickly, absorbing a large amount of heat, thereby reducing the heat of the water. The water falls to the top of the partition 32. After that, the water 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 improving the purity of the water. This prevents the water from becoming turbid and being directly heated and vaporized by the laser, reducing the generation of water vapor in the water tank 7. This also prevents the circuit in the housing 1 from malfunctioning due to high humidity, ensuring the circuit safety of the equipment. Impurities are pushed upward by the screw plate 24 inside the filter cartridge 26. As the amount of impurities increases, 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 drain pipe 27, ensuring the filtration efficiency of the filter cartridge 26 and facilitating the separation of impurities.

[0028] In this embodiment, the air box 14 is installed on the outside of the housing 1. The laser cutter 2 is a liquid-cooled laser cutter. The water pump 15 is bolted to the outside of the air box 14. The branch pipe 16 is welded to the outside of the air box 14. One side of the water pump 15 is connected to the top of the laser cutter 2, and the top of the water pump 15 is connected to the branch pipe 16. One end of the cooling pipe 17 is connected to the branch pipe 16, and the other end of the cooling pipe 17 is coiled inside the air box 14 and connected to one side of the branch pipe 16. The other side of the branch pipe 16 is connected to the bottom of the laser cutter 2 via a connecting pipe 20. The air duct 18 is welded to the top of the air box 14. The fan 19 is bolted to the inside of the air duct 18. The return pipe 22... A conduit 43 is welded to the air box 14, and the return pipe 22 is connected to the clamp 25 through the conduit 43. A pressure relief valve 44 is installed on the conduit 43. A nylon mesh 35 is adhered to the inner wall of the air box 14 and is installed on the top of the nozzle 28. A cavity 37 is welded to the top of the branch pipe 16, and a sliding sleeve 38 is welded to the top of the cavity 37. The sliding sleeve 38 is connected to the cavity 37, and a piston 39 is clamped inside the sliding sleeve 38. An electrode 40 is welded to the inner wall of the sliding sleeve 38, and a button 41 is provided 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. In use, the fan 19 generates suction on the air box 14 through the air duct 18, causing the air to be filtered through the filter screen 31. The air is then drawn into the inside of the air box 14 through the air duct 33 and air outlet 34. After the air is cooled by water mist, it passes through the nylon mesh 35 and the water droplets attached to it. The cold air flows upward on the outside of the cold pipe 17. The water pump 15 pumps the coolant of the laser cutter 2 to the inside of the branch pipe 16. The coolant is distributed through the branch pipe 16 to the inside of multiple cold pipes 17, where it is cooled. After being merged through the branch pipe 16, it enters the inside of the laser cutter 2 through the connecting pipe 20 to cool the laser cutter 2 and ensure its safe operation. If the temperature of the coolant in the branch pipe 16 is high, the air in the cavity 37 expands and pushes the piston 39 upward. The piston 39 contacts the electrode 40. According to the coolant temperature... The temperature control electrode 40 opens the solenoid valve 30 to adjust the amount of water spray, thereby adjusting the cooling efficiency of the air and the cooling rate of the coolant to ensure the safe operation of the laser cutter 2. When the piston 39 presses the button 41, the button 41 adjusts the power of the motor 23 through the frequency converter 36 to ensure the pushing pressure of the water and thus ensure the atomization effect. If the pushing pressure of the motor 23 on the water through the screw plate 24 is too high, 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 water from directly pushing open the pressure valve and flowing outward, thus avoiding the waste of water resources. The evaporation of water is used for cooling and temperature reduction, which not only ensures the heat dissipation safety of the laser cutter 2 but also reduces the energy consumption of heat dissipation.

[0029] This laser cutting equipment for adhesive strips is powered by an external power supply. During operation, motors 3 and 5 drive the adhesive strip to the right inside the housing 1 via rollers 4 and conveyor 6, respectively, until the right end of the adhesive strip reaches the bottom of the length measuring device 13. This ensures the distance between the right end of the adhesive strip and the laser cutter 2 is equal to the required length. The adhesive strip then pushes the bottom of the length measuring device 13 upwards, triggering the switch to open the laser cutter 2 for cutting. The penetrating laser enters the inside of the water tank 7, where it is scattered by water and prism 8, reducing its density. The laser is absorbed by an iron plate 9, which is then cooled by water. This effectively absorbs the energy of the laser during cutting, preventing damage to the equipment. The bottom is damaged, ensuring equipment safety. Debris from the cutting process and impurities carried by the rubber strip fall into the inside of the water tank 7. Motor 4 23 drives the screw plate 24 to rotate inside the sleeve 21, causing the sleeve 21 to draw water and impurities from the water tank 7 into its inner side. After being filtered by the filter cartridge 26, the water enters the spray pipe 28 through the clamp 25, and then is atomized and sprayed out through the nozzle 29 inside the air box 14. The airflow inside the air box 14 causes the water mist to evaporate rapidly, absorbing a large amount of heat and thus reducing the water's temperature. After falling to the top of the partition 32, the water flows back into the inside of the water tank 7 through the return pipe 22, effectively lowering the water temperature in the water tank 7 and improving the water's purity, preventing the top from becoming cloudy. The moisture in the filter cartridge 26 is directly vaporized by laser heating, reducing the generation of water vapor in the water tank 7. This prevents circuit malfunctions in the housing 1 due to high humidity, ensuring the safety of the equipment's circuitry. Impurities are pushed upwards by the screw plate 24 on the inner side of the filter cartridge 26. As the amount of impurities increases, the pushing force of the screw plate 24 on the impurities increases, causing the impurities to open the pressure valve and be discharged outwards through the drain pipe 27. This ensures the filtration efficiency of the filter cartridge 26 and facilitates the separation of impurities. The fan 19 generates suction on the air box 14 through the air duct 18, causing air to be filtered by the filter screen 31 and then drawn into the inner side of the air box 14 through the air duct 33 and the air outlet 34. The air is cooled by water mist and then passes through the water droplets attached to the nylon mesh 35. The cold air then flows upwards on the outer side of the cooling pipe 17. Water pump 15 pumps the coolant from the laser cutter 2 to the inside of the branch pipe 16. The coolant is then distributed through the branch pipe 16 to the inside of multiple cooling pipes 17 for cooling. After being collected again through the branch pipe 16, the coolant enters the inside of the laser cutter 2 through the connecting pipe 20 to further cool the laser cutter 2 and ensure its safe operation. If the temperature of the coolant in the branch pipe 16 is 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 opened by the control electrode 40 according to the coolant temperature is adjusted, thereby regulating the water spray volume, the cooling efficiency of the air, and the cooling rate of the coolant, to ensure the safe operation of the laser cutter 2.When piston 39 presses button 41, button 41 adjusts the power of motor 23 via frequency converter 36 to ensure the pushing pressure on water, thereby ensuring the atomization effect. If the pushing pressure of motor 23 on water via screw plate 24 is too high, the water pressure opens the pressure relief valve 44 and flows through conduit 43 to the inside of return pipe 22, preventing water from directly pushing open the pressure valve and flowing outward, thus avoiding water waste. The evaporation of water is used for cooling, ensuring the heat dissipation safety of laser cutter 2 and reducing energy consumption for heat dissipation.
