Description

Technical Field

[0001] This application relates to the field of marking machines, and in particular to a reflective printing lettering film marking machine. Background Technology

[0002] A marking machine is an automated device specifically designed for high-precision engraving, cutting, or pattern marking on the surface of reflective printed lettering films (such as PVC and PET materials). Its core principle is to selectively process the material surface using a laser beam or mechanical cutters to create reflective text, graphics, or logos. This equipment is widely used in fields such as safety clothing, bags and accessories, and traffic signs, enabling both personalized customization and mass production.

[0003] During operation, laser or mechanical processing generates high temperatures, causing localized material vaporization and the release of fumes. Existing solutions generally use fans to extract the fumes. However, when the marking head moves to different positions, the distance and angle between the fixed fan and the fumes source cannot be adjusted synchronously, resulting in some fumes not being effectively extracted and polluting the working environment.

[0004] Regarding the aforementioned technologies, the inventors believe that the marking machine has the defect of incomplete smoke treatment during processing. Therefore, they have proposed a reflective printing and lettering film marking machine to solve the above problems. Utility Model Content

[0005] In order to solve the problem of incomplete smoke treatment during the processing of marking machines, this application provides a reflective printing lettering film marking machine.

[0006] The reflective printing and lettering film marking machine provided in this application adopts the following technical solution:

[0007] A reflective printing and lettering film marking machine includes a marking device. A processing section is provided on the upper surface of the marking device. A support frame is fixedly installed on one side of the processing section. A smoke exhaust pipe is located at the center of the back of the marking device. A main exhaust fan is installed at an opening on one side of the inner wall of the smoke exhaust pipe. A fixed pipe is fixedly installed through the support frame on one side of the smoke exhaust pipe. Sealing gaskets are welded to both sides of the fixed pipe. A movable pipe is symmetrically and movably installed inside the fixed pipe. A connector is rotatably installed on one side of the outer surface of the movable pipe via a bearing seat. An adjusting frame is fixedly installed on one side of the connector. A connecting hose connects the movable pipe and the adjusting frame. Several fixing holes are opened on one side of the inner wall of the adjusting frame. A secondary exhaust fan is installed inside each fixing hole. A spacing adjustment mechanism is also provided on the outer surface of the support frame for controlling the movement of the movable pipe.

[0008] Preferably, the spacing adjustment mechanism includes a fixing member, which is fixedly installed on the upper surface of the movable tube near the connector. The bottom of the front end face of the support frame is symmetrically welded with fixing plates. A bidirectional lead screw is rotatably installed between the two fixing plates through the fixing member. A second self-locking servo motor is provided on one side of the bidirectional lead screw.

[0009] Preferably, a self-locking servo motor is mounted on the top hinge shaft of the connector, which passes through the upper surface of the bearing seat, and several smoke sensors are fixedly mounted on the upper surface of the adjustment frame.

[0010] Preferably, one side of the outer surface of the movable tube abuts against the inner wall of the sealing gasket, and one side of the movable tube extends to the outside of the fixed tube, with the fixed tube and the movable tube interlocking with each other.

[0011] Preferably, a threaded hole is provided through the middle of one side of the fixing member, and external threads with opposite thread patterns are provided on both sides of the outer surface of the bidirectional lead screw, and the bidirectional lead screw and the threaded hole are mutually adapted.

[0012] In summary, this application includes the following beneficial technical effects:

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a reflective printing and lettering film marking machine. (See also...) Figure 1-3 A reflective printing and lettering film marking machine includes a marking device 1. A processing section 2 is provided on the upper surface of the marking device 1. A support frame 3 is fixedly installed on one side of the processing section 2. A smoke exhaust pipe 4 is provided at the middle position of the back of the marking device 1. A main exhaust fan 5 is installed at the opening on one side of the inner wall of the smoke exhaust pipe 4. A fixed pipe 6 is fixedly installed through the support frame 3 on one side of the smoke exhaust pipe 4. Sealing gaskets 7 are welded to both sides of the fixed pipe 6. A movable pipe 8 is symmetrically and movably installed inside the fixed pipe 6. One side of the outer surface of the movable pipe 8 abuts against the inner wall of the sealing gasket 7, and one side of the movable pipe 8 extends to the outside of the fixed pipe 6. 6 and movable tube 8 are interlocked. A connector 9 is rotatably mounted on one side of the outer surface of movable tube 8 via a bearing seat. An adjusting frame 10 is fixedly mounted on one side of connector 9. A connecting hose 11 connects movable tube 8 and adjusting frame 10. Several fixing holes 12 are opened on one side of the inner wall of adjusting frame 10. A secondary exhaust fan 13 is installed inside the fixing holes 12. A self-locking servo motor 14 is mounted on the top hinge shaft of connector 9 through the upper surface of bearing seat. Several smoke sensors 15 are fixedly mounted on the upper surface of adjusting frame 10. A spacing adjustment mechanism is also provided on the outer surface of support frame 3 to control the movement of movable tube 8.

[0020] The smoke sensor 15 monitors the smoke concentration near the processing unit 2 in real time and provides feedback. The first self-locking servo motor 14 starts and drives the adjusting frame 10 to rotate through the connector 9, adjusting the angle of the auxiliary exhaust fan 13 to make it closer to the smoke generation point. The main exhaust fan 5 and the auxiliary exhaust fan 13 work simultaneously, and the smoke enters the exhaust pipe 4 through the connecting hose 11, the movable pipe 8, and the fixed pipe 6 and is discharged.

[0021] Reference Figure 1 and Figure 2 The spacing adjustment mechanism includes a fixing component 16, which is fixedly installed on the upper surface of the movable tube 8 near the connector 9. The bottom of the front end face of the support frame 3 is symmetrically welded with fixing plates 17. A bidirectional lead screw 18 is rotatably installed between the two fixing plates 17, passing through the fixing component 16. A second self-locking servo motor 19 is provided on one side of the bidirectional lead screw 18. A threaded hole is opened through the middle of one side of the fixing component 16. The two sides of the outer surface of the bidirectional lead screw 18 are respectively provided with external threads with opposite thread patterns. The bidirectional lead screw 18 and the threaded hole are mutually compatible.

[0022] By starting the second self-locking servo motor 19, the bidirectional lead screw 18 is driven to rotate. Since the bidirectional lead screw 18 is threadedly matched with the fixing part 16, the fixing part 16 drives the movable tube 8 to move within the fixed tube 6, thereby adjusting the lateral position of the auxiliary exhaust fan 13.

[0023] The implementation principle of the reflective printing and lettering film marking machine in this application embodiment is as follows: The smoke sensor 15 monitors and provides feedback on the smoke concentration near the processing unit 2 in real time. When the smoke exhaust position needs to be adjusted, the second self-locking servo motor 19 starts, driving the bidirectional lead screw 18 to rotate. Since the bidirectional lead screw 18 is threadedly matched with the fixing member 16, the fixing member 16 drives the movable tube 8 to move within the fixed tube 6, adjusting the lateral position of the auxiliary exhaust fan 13. Simultaneously, the first self-locking servo motor 14 starts, driving the adjusting frame 10 to rotate via the connecting member 9, adjusting the angle of the auxiliary exhaust fan 13 to make it closer to the smoke generation point. The main exhaust fan 5 and the auxiliary exhaust fan 13 work simultaneously, and the smoke enters the exhaust pipe 4 through the connecting hose 11, the movable tube 8, and the fixed tube 6 for discharge. The input terminals of the power supplies of the No. 1 self-locking servo motor 14 and the No. 2 self-locking servo motor 19 are electrically connected to the output terminals of the external power supply. The sealing gasket 7 ensures the sealing of the movable tube 8 when it moves, ensuring efficient smoke collection, solving the problem of incomplete smoke treatment in traditional marking machines, and improving the quality of the marking environment and marking accuracy.
