Description

Technical Field

[0001] This application relates to the technical field of laser equipment, and in particular to a transverse air knife for laser equipment. Background Technology

[0002] Air knives, including strip air knives and ring air knives, are devices specifically designed to generate a powerful, high-speed airflow to remove dust, dry water stains, and cool the air. There is also a type of air knife used for cutting sheet metal. Air knives consist of a high-intensity, uniform laminar airflow.

[0003] In the prior art, Chinese Patent Publication No. CN219254480U discloses a transverse air knife for laser equipment. This technology employs an air knife box with two sets of symmetrically distributed air knife nozzles. Air tubes are connected to the air knife nozzles. A top plate is connected to the upper end of the air knife box, and a lens fixing mechanism is connected to the surface of the top plate to fix the laser equipment lens. An upper limit platform is connected to the upper end of the air knife nozzle, and a lower limit platform is connected to the lower end of the upper limit platform. The lower and upper limit platforms limit the movement of the air knife nozzles. A welding slag collection mechanism is installed below each air knife nozzle to collect welding slag blown out by the opposite air knife nozzle. It can rotate between the lower and upper limit stages. The rotation angle of the air knife nozzle is greater than 270° and less than 360°, which enables the air knife nozzle to form an air curtain by ejecting compressed air. This air curtain blocks the upward-splashing welding chips from the welding and cutting area, preventing the welding chips from splashing onto the surface of the laser equipment lens and causing damage to the lens. Furthermore, the two sets of air knife nozzles form two sets of intersecting compressed air curtains, which can provide comprehensive protection for the laser equipment lens. At the same time, the intersection of the two sets of compressed air curtains is located on one side of the laser equipment lens, so that an upward airflow is generated at the intersection point, causing the welding chips to be pushed onto the surface of the lens by the compressed air and causing damage to the lens.

[0004] However, in practical applications, the required gas intensity varies depending on the object being cut. The strong, high-speed airflow from the air knife nozzle described above cannot be increased according to the intensity of the object being cut.

[0005] Therefore, those skilled in the art have provided a transverse air knife for laser devices to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the issue raised in the background art that the required gas intensity varies depending on the object being cut, and that the strong, high-speed airflow from the air knife nozzle described above cannot be adjusted according to the intensity of the object being cut, this application provides a transverse air knife for laser equipment.

[0007] This application provides a transverse air knife for laser equipment, employing the following technical solution: It includes an air knife box, with a sealing baffle on the front. Connecting heads are fixedly connected to both sides of the top of the air knife box. One end of each connecting head is connected to an air pipe, and the other end to a telescopic flexible hose. The other end of the telescopic flexible hose is connected to an air knife nozzle. The air knife nozzle is placed inside a placement block. Second screws are threaded to both ends of the placement block. A fixing block is threaded to the outer surface of the second screws. Rotating rods are fixedly connected to both sides of the fixing blocks. A first gear is fixedly connected to one end of the rotating rod that passes through the air knife box. A second gear meshes with the outer surface of the first gear. The output shaft of a motor is internally connected to the second gear. The motor is fixedly mounted on the surface of the air knife box.

[0008] Preferably, the end of the connector that is not connected to the telescopic hose has a plug threaded onto its surface.

[0009] Preferably, the inner sides of the fixing block and the placement block are respectively provided with a fixing groove and a placement groove, and the fixing groove and the placement groove form a complete locking groove, which is used to lock the air knife nozzle.

[0010] Preferably, a support base is rotatably connected to the outer surface of another rotating rod, and the bottom of the support base is fixedly installed on the inner wall of the air knife box.

[0011] Preferably, the air knife box has a laser channel at its center.

[0012] Preferably, both sides of the sealing baffle are threaded with a first screw, one end of the first screw passes through the connecting head and is threadedly connected to the air knife box, and the air knife box has a screw hole inside that matches the size of the first screw.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By setting up a placement block, a second screw, and a fixing block, the second screw is rotated to disengage from the inner wall of the placement block, releasing the fixing block from the placement block. Then, a new air knife nozzle is placed in the placement slot, or the air knife nozzle is removed from the placement slot. Then, the fixing block is covered to make the fixing slot hold the air knife nozzle, thereby increasing or decreasing the number of air knife nozzles according to the intensity of the ejected airflow.

[0015] 2. By setting up a motor, a second gear, and a first gear, the motor drives the first gear to rotate through the second gear. The rotation of the first gear drives the rotating rod to rotate. The rotation of the rotating rod drives the air knife nozzle to rotate through the fixed block. Adjusting the angle of the air knife nozzle allows the compressed air curtain ejected by the air knife nozzle to effectively block the sputtered welding chips. The air curtain formed can also effectively blow the welding chips away from the surface of the laser equipment lens. Attached Figure Description

[0021] The following will be combined with the appendix Figure 1-4 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application discloses a transverse air knife for a laser device, as shown in the embodiments below. Figure 1-4The air knife box 1 is characterized in that a sealing baffle 2 is provided on the front of the air knife box 1, and a sealing gasket is provided on the inner side of the sealing baffle 2 to increase the sealing between the sealing baffle 2 and the air knife box 1. A first screw 3 is threadedly connected to both sides of the sealing baffle 2. One end of the first screw 3 passes through a connecting head 5 and is threadedly connected to the air knife box 1. A screw hole 4 matching the size of the first screw 3 is opened inside the air knife box 1. Connecting heads 5 are fixedly connected to both sides of the top of the air knife box 1. A plug is threadedly connected to one end of the connecting head 5 that is not connected to the telescopic hose. The cap is used to block the connecting head 5, which is not connected to the telescopic hose. One end of the connecting head 5 is connected to the air pipe, and the other end is connected to the telescopic hose. The other end of the telescopic hose is connected to the air knife nozzle 6. The air knife nozzle 6 is placed in the placement block 7. Both ends of the placement block 7 are threaded with the second screw 8, and the outer surface of the second screw 8 is threaded with the fixing block 9. By setting the placement block 7, the second screw 8, and the fixing block 9, the number of air knife nozzles 6 can be increased according to the speed of the strong high-speed airflow required, so as to facilitate the installation of the air knife nozzle 6.

[0023] The inner sides of the fixing block 9 and the placement block 7 are respectively provided with a number of fixing grooves 91 and a number of placement grooves 71. The number of fixing grooves 91 and the number of placement grooves 71 form a complete set of several slots. Each slot is used to lock the air knife nozzle 6. By setting a number of slots, the air knife nozzle 6 can be locked or released.

[0024] In this application, rotating rods 10 are fixedly connected to both sides of the fixing block 9. A support base 15 is rotatably connected to the outer surface of another rotating rod 10. The bottom of the support base 15 is fixedly installed on the inner wall of the air knife box 1. A first gear 11 is fixedly connected to one end of the rotating rod 10 that passes through the air knife box 1. A second gear 12 meshes with the outer surface of the first gear 11. The output shaft of the motor 13 is internally connected to the second gear 12. The motor 13 is fixedly installed on the surface of the air knife box 1. A laser channel 14 is opened in the center of the air knife box 1. By setting the motor 13, the second gear 12, the first gear 11, the rotating rod 10, and the fixing block 9, the angle of the air jet from the air knife nozzle 6 is adjusted so that the compressed air curtain can block the sputtered welding chips. The air curtain can also effectively blow the welding chips away from the surface of the laser equipment lens.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] The implementation principle of a transverse air knife for laser equipment according to an embodiment of this application is as follows: In use, the first screw 3 is rotated to disengage from the inside of the air knife box 1, releasing the fixation of the sealing baffle 2 and opening the air knife box 1. Then, the second screw 8 is rotated to disengage from the inner wall of the placement block 7, releasing the fixation between the fixing block 9 and the placement block 7. A new air knife nozzle 6 is then placed in the placement groove 71, or the air knife nozzle 6 is removed from the placement groove 71. The fixing block 9 is then covered, causing the fixing groove 91 to hold the air knife nozzle 6. The second screw 8 is then rotated through the fixing block 9 and inserted into the inside of the placement block 7 to complete the fixation of the air knife nozzle 6. The air knife nozzle 6 is then connected to the connecting head 5 via a telescopic hose, and the connecting head 5 is then connected to the air pipe. To increase the number of air knife nozzles 6, disconnect the connection between the connecting head 5 and the telescopic hose, and then block the connecting head 5 with a plug to reduce the number of air knife nozzles 6. This achieves the effect of increasing or decreasing the number of air knife nozzles 6 according to the intensity of the ejected airflow. Start the motor 13 to drive the second gear 12 to rotate. The rotation of the second gear 12 drives the first gear 11 to rotate. The rotation of the first gear 11 drives the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the air knife nozzles 6 to rotate through the fixing block 9. Adjust the angle of the air knife nozzles 6 so that the compressed air curtain ejected by the air knife nozzles 6 can effectively increase the blocking of sputtered welding chips. The air curtain formed can also effectively blow the welding chips away from the surface of the laser equipment lens.
