Description

Technical Field

[0001] The invention relates to the technical field of laser marking, in particular to an online laser marking device for textiles. Background Art

[0002] Laser marking machines are often used in intelligent welding systems and intelligent heat treatment production lines. The working principle of a laser marking machine is to focus the laser at an extremely high energy density on the surface of the object to be marked, vaporize the surface material through burning and etching, and accurately burn out patterns or text by controlling the effective displacement of the laser beam. When using existing laser marking machines, textiles are usually transported to the lower side of the laser marker and then laser marked. However, the textiles may have wrinkles, which affects the marking effect, and the textiles need to be stopped during marking to ensure that the position of the lighter fabric does not change. When the number of laser markings is large, repeated stops will cause certain damage to the transportation equipment and affect the service life of the device.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] See also Figures 1 to 10 The present invention provides a technical solution: an online laser marking device for textiles, comprising a support frame 1, wherein a conveyor belt 2 is installed in the support frame 1, and the conveyor belt 2 includes an active roller 3 and a driven roller 4. A first driving structure is installed on one side of the support frame 1, and the first driving structure corresponds to the active roller 3. A winding roller 10 and a discharge roller 12 are installed in the support frame 1, and a first rotating shaft 11 and a second rotating shaft 13 are rotatably matched in the support frame 1. A connecting structure is installed between the first rotating shaft 11 and the winding roller 10, and between the second rotating shaft 13 and the discharge roller 12. A second driving structure is installed on one side of the support frame 1, and the second driving structure corresponds to the first rotating shaft 11. The structure of the first driving structure is the same as that of the second driving structure. A sliding plate 18 is slidably matched in the support frame 1, and a sliding structure and a fixed structure are installed on the sliding plate 18. A laser marker 23 is installed on the sliding structure, and a template 29 is installed on the fixed structure. The template 29 corresponds to the laser marker 23. A flatness detection structure is slidably matched on the support frame 1, and a scraping structure is installed on the flatness detection structure.

[0033] In this embodiment, a plurality of auxiliary rollers 5 are rotatably fitted in the support frame 1, and the auxiliary rollers 5 correspond to the conveyor belt 2. The first drive structure and the second drive structure both include a reducer 6 and a motor 7. The reducer 6 includes a first gear 8 and a second gear 9, an input shaft and an output shaft. The first gear 8 is meshed with the second gear 9. One side of the second gear 9 is a smooth structure, and the other side of the meshing second gear 9 is provided with teeth. The output end of the motor 7 is fixedly connected to the input shaft, the input shaft is fixedly connected to the axial center of the second gear 9, the output shaft is fixedly connected to the first gear 8, the output shaft of the first drive structure is fixedly connected to the active roller 3, and the output shaft of the second drive structure is fixedly connected to the first rotating shaft 11.

[0034] Specifically, when textiles need to be transported, for cloth, the cloth can be wound around the unwinding roller 12, and one end of the cloth can be wound around the winding roller 10, and the winding roller 10 can be driven to rotate by the second drive structure to wind the cloth; for shorter textiles such as clothing, the textiles can be directly placed on the conveyor belt 2, and then the first drive structure can be started, and the conveyor belt 2 can be driven to work by the first drive structure, so that the textiles can be transported. Starting the motor 7 causes the motor 7 to drive the input shaft to rotate, thereby driving the second gear 9 to rotate, causing the first gear 8 to mesh with the second gear 9 to rotate, thereby driving the first gear 8 to rotate, causing the first gear 8 to drive the output shaft to rotate, which can drive the winding roller 10 to rotate to reel the cloth or drive the conveyor belt 2 to transport the cloth; when the side of the second gear 9 with teeth meshes with the first gear 8, the second gear 9 can drive the first gear 8 to rotate. When the second gear 9 rotates to the smooth side, the first gear 8 is not in contact with the second gear 9, so the rotation of the second gear 9 does not drive the first gear 8 to rotate. At this time, the textile is stopped from being transported, but the motor 7 does not stop working, thereby ensuring that the textile is in a stationary state, facilitating laser marking of the textile, preventing the textile from failing to be marked due to transportation during laser marking, ensuring the success rate of laser marking on the textile, and achieving a better laser marking effect. There is no need to repeatedly shut down the motor 7, thereby preventing the motor 7 from being damaged due to repeated shutdown, thereby extending the service life of the motor 7.

[0035] The connecting structure includes a first mounting block 15 fixed on the first rotating shaft 11 and the second rotating shaft 13, and a second mounting block 16 is fixed on the winding roller 10 and the unwinding roller 12. A nut 14 is installed between the first mounting block 15 and the second mounting block 16. The nut 14 is threadedly engaged with the first mounting block 15 and the second mounting block 16. The first mounting block 15 and the second mounting block 16 are combined to form a cylindrical structure.

[0036] Specifically, for cloth-like textiles, when it is necessary to unload the textiles after marking, the nut 14 is rotated so that the nut 14 slides to the second mounting block 16. At this time, the nut 14 is separated from the first mounting block 15, so that the nut 14 no longer limits the first mounting block 15, so that the first mounting block 15 is separated from the second mounting block 16. The nuts 14 are rotated on both sides of the winding roller 10 to remove the winding roller 10, so that the winding roller 10 can be replaced and the marked textiles can be unloaded. Similarly, the disassembly and replacement of the discharge roller 12 can be completed. It is convenient to disassemble and install the winding roller 10 and the discharge roller 12, which facilitates the loading and unloading of cloth-like textiles and improves work efficiency.

[0037] A first electric cylinder 17 is fixed on the support frame 1, and the output end of the first electric cylinder 17 is fixedly connected to the sliding plate 18. The sliding structure includes a first electric slide rail 19 fixed on the sliding plate 18, and a first sliding block 20 is fixed to the output end of the first electric slide rail 19. A second electric slide rail 21 is fixed to the lower side of the first sliding block 20, and a second sliding block 22 is fixed to the output end of the second electric slide rail 21. The second sliding block 22 is fixedly connected to the laser marker 23.

[0038] Specifically, by starting the first electric cylinder 17, the sliding plate 18 can be driven to slide up and down by the first electric cylinder 17, thereby driving the laser marker 23 to approach or move away from the textile, which not only facilitates the laser marker 23 to laser mark the textile, but also can adjust the distance between the laser marker 23 and the textile to prevent the laser marker 23 from affecting the movement of the textile, and at the same time makes the laser marker 23 suitable for textiles of different thicknesses, expanding the scope of application of the device; by starting the first electric slide 19, the first sliding block 20 can be driven to move by the first electric slide 19, thereby driving the second electric slide 21 to move, which can drive The laser marker 23 on the second electric slide rail 21 moves, and the second electric slide rail 21 is started, so that the second sliding block 22 can be driven to slide by the second electric slide rail 21, thereby driving the laser marker 23 to slide. The first electric slide rail 19 is perpendicular to the second electric slide rail 21, so that the laser marker 23 can be driven to move to any position in the plane, so that the laser marker 23 can be driven by the first electric slide rail 19 and the second electric slide rail 21 to perform laser marking of any shape, thereby expanding the scope of application of the device, preventing laser marking failure due to restricted movement of the laser marker 23, and improving the success rate of laser marking.

[0039] The fixed structure includes an elastic telescopic rod 24, which is fixedly connected to the sliding plate 18. The elastic telescopic rod 24 includes a first rod body 25 and a second rod body 26. A sliding groove is provided in the first rod body 25, and the sliding groove corresponds to the second rod body 26. A first spring 27 is fixed between the second rod body 26 and the groove wall of the sliding groove, and a pressure block 28 is fixed at the end of the second rod body 26.

[0040] Specifically, when the laser marker 23 is used for laser marking, the first electric cylinder 17 is started, and the laser marker 23 is driven to move downward by the first electric cylinder 17. At the same time, the sliding plate 18 drives the elastic telescopic rod 24 to move downward, so that the pressing block 28 moves downward, thereby driving the template 29 to move downward until the template 29 contacts the textile. Not only can the template 29 limit the range of laser marking, but also play a certain positioning effect on laser marking, preventing the laser from damaging the textile outside the marking position, but also squeezing and fixing the textile to prevent the textile from moving during the laser marking process, preventing the laser marking from failing due to the movement of the textile during the laser marking process, and improving the success rate of laser marking; if the laser marker 23 continues to move downward at this time, the second rod body 26 slides relatively in the slide groove, and the first spring 27 is compressed, thereby preventing the elastic telescopic rod 24 from limiting the movement of the laser marker 23, ensuring the range of motion of the laser marker 23, thereby ensuring the effect of laser marking.

[0041] Furthermore, a card block 31 is fixed on the template 29, and the card block 31 has a C-shaped structure. The card block 31 corresponds to the pressure block 28, and a card ball 41 is installed in the card block 31. A card slot is provided in the pressure block 28, and the card slot corresponds to the card ball 41. The card block 31 and the card ball 41 are both made of elastic material. A mold groove 30 is provided in the template 29, and the mold groove 30 corresponds to the laser marker 23.

[0042] Specifically, the template 29 can press down and fix the textile, and the laser marking position of the laser marker 23 can be positioned through the mold groove 30, thereby ensuring the effect of laser marking. The textile is shielded by the template 29 to prevent laser marking from damaging the textile except the marking position, thereby ensuring the beauty of the textile, and the template 29 can be replaced to make it suitable for different laser marking shapes. When the template 29 needs to be disassembled, the template 29 can be pulled up or down to separate the card ball 41 from the card slot, and the card block 31 produces a large deformation, so that the pressure block 28 no longer limits the card block 31, and the template 29 can be removed, thereby facilitating the disassembly and replacement of the template 29. By replacing the template 29, the device is suitable for textiles with different marking shapes, thereby expanding the scope of application of the device.

[0043] A third electric slide rail 32 is fixed on the support frame 1, and the flatness detection structure includes a detection rod 34. A third sliding block 33 is fixed to the output end of the third electric slide rail 32, and a second electric cylinder 42 is fixed to the lower side of the third sliding block 33. The output end of the second electric cylinder 42 is fixedly connected to the detection rod 34.

[0044] Specifically, before laser marking, the flatness of the textile is detected to prevent wrinkles from forming on the textile. The third electric slide 32 is started so that the third electric slide 32 drives the detection rod 34 to slide, and the flatness of the textile can be detected. For textiles with wrinkles, the textile can be simply scraped flat by the detection rod 34, or directly flattened manually to prevent wrinkles from blocking the laser marking and causing marking failure, thereby ensuring the effect of laser marking. After the detection is completed, it moves to the side to prevent the movement of the laser marker 23 from being limited, thereby ensuring the marking effect of the laser marker 23. Starting the second electric cylinder 42 can also drive the detection rod 34 to slide up and down, thereby adjusting the distance between the detection rod 34 and the textile, so that the detection rod 34 can detect textiles of different thicknesses, expanding the scope of application of the device.

[0045] A groove 35 is provided in the detection rod 34, and a pressure head 39 is slidably fitted in the groove 35. A second spring 36 is fixed between the pressure head 39 and the groove wall of the groove 35. A pressure sensor 37 is fixed in the groove 35. A rotating groove is provided in the pressure head 39, and a ball 40 is rotatably fitted in the rotating groove. The ball 40 corresponds to the rotating groove. The scraping structure includes multiple scraping rods 38, and the multiple scraping rods 38 are respectively fixed on both sides of the detection rod 34.

[0046] Specifically, when the flatness of the textile is detected, the third electric slide rail 32 is started, so that the third electric slide rail 32 drives the detection rod 34 to slide, and the ball 40 slides on the textile. When encountering wrinkles, the wrinkles cause the thickness to be relatively high, which will squeeze the ball 40 upward, causing the ball 40 to move relatively upward, driving the pressure head 39 to move relatively upward, the second spring 36 is compressed, the pressure head 39 completely enters the groove 35, and the pressure sensor 37 is squeezed. At this time, the scraper rod 38 contacts the wrinkles, and the wrinkles are scraped flat as the detection rod 34 slides, thereby preventing the wrinkles from affecting the laser marking process and improving the success rate of laser marking.

[0047] Working process: For fabric textiles, the unwinding roller 12 and the winding roller 10 wrapped with the fabric are installed on the support frame 1, and then the motor 7 is started, so that the motor 7 drives the input shaft to rotate, thereby driving the second gear 9 to rotate, so that the first gear 8 and the second gear 9 are engaged and rotated, thereby driving the first gear 8 to rotate, so that the first gear 8 drives the output shaft to rotate, which can drive the winding roller 10 to rotate to reel the fabric, thereby driving the fabric to move, and the fabric can be laser marked. When the side of the second gear 9 with teeth is engaged with the first gear 8, the second gear 9 can drive the first gear 8 to rotate. When the second gear 9 rotates to the smooth side, the first gear 8 The second gear 36 is not in contact with the second gear 9, so the rotation of the second gear 9 does not drive the first gear 8 to rotate. At this time, the textile is stopped from being transported, so the cloth stops working, and the third electric slide 32 is started, so that the third electric slide 32 drives the detection rod 34 to slide, and the ball 40 slides on the textile. When a wrinkle is encountered, the wrinkle causes the thickness to be relatively high, which will squeeze the ball 40 upward, causing the ball 40 to move upward relatively, driving the pressure head 39 to move upward relatively, the second spring 36 is compressed, and the pressure head 39 completely enters the groove 35, and the pressure sensor 37 is squeezed. At this time, the scraper rod 38 is in contact with the wrinkle, thereby scraping the wrinkle flat as the detection rod 34 slides. When After scraping, the detection rod 34 slides to one side to prevent it from affecting the sliding of the laser marker 23, and then the first electric cylinder 17 is started, which can drive the sliding plate 18 to slide downward through the first electric cylinder 17, thereby driving the laser marker 23 close to the textile, and the sliding plate 18 will drive the elastic telescopic rod 24 to move downward, so that the pressure block 28 moves downward, thereby driving the template 29 to move downward until the template 29 contacts the textile. At this time, the laser marker 23 continues to move downward, and the second rod body 26 slides relatively in the slide groove, and the first spring 27 is compressed, thereby preventing the elastic telescopic rod 24 from limiting the movement of the laser marker 23, thereby ensuring the motion range of the laser marker 23. After sliding down to the appropriate position, start the first electric slide 19, and the first sliding block 20 can be driven to move by the first electric slide 19, thereby driving the second electric slide 21 to move, and the laser marker 23 on the second electric slide 21 can be driven to move. Start the second electric slide 21, and the second sliding block 22 can be driven to slide by the second electric slide 21, thereby driving the laser marker 23 to slide. The first electric slide 19 is perpendicular to the second electric slide 21, so that the laser marker 23 can be driven to move to any position in the plane, so that the laser marker 23 can be driven by the first electric slide 19 and the second electric slide 21 to perform laser marking of any shape.

[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
