Description

Technical Field

[0001] This disclosure relates to the field of laser marking technology, and more particularly to a laser marking machine for leather. Background Technology

[0002] Leather laser marking machines are opto-mechatronic devices that integrate laser technology and computer technology. They generate laser light, which is then focused by a focusing lens and irradiated onto the surface of the object to be marked, forming a mark. However, the overall performance of leather laser marking machines on the market is relatively poor. In addition, the marking effect on leather is relatively poor, as some impurities or dirt on the leather surface are easily adhered to and cannot be removed, which will affect the marking effect.

[0003] According to patent document CN214921460U, a laser marking machine for leather processing with anti-misalignment capability is disclosed. It includes a base with a support frame fixedly mounted on its upper surface. A controller is mounted on the right side of the support frame, and a marking mechanism is mounted on the left side of the support frame. A support frame is welded to the upper end of the base, with lead screws rotatably connected to both sides of the support frame. A side groove is formed on the front side of the base, and a side slider is fitted inside the side groove. A fixing rod has one end connected to the side slider, and an adjusting block is fixedly mounted on the other end of the fixing rod. An mounting bracket is fixed on the upper surface of the adjusting block. The proposed solution employs a novel structural design, allowing for convenient clamping and positioning of leather products within the marking machine to prevent misalignment during marking. The device also includes a leather clamping position adjustment mechanism, enabling direct repositioning of the clamped leather product during processing for continuous handling. However, while this solution adjusts the leather's position through clamping, it cannot remove surface fuzz and impurities during marking. Furthermore, it cannot effectively tighten and flatten the leather during marking, resulting in inconvenience in use. Summary of the Invention

[0012] Optionally, a mounting seat is movably mounted inside the mounting groove. The mounting seat is welded to the side of the limiting seat. A DC motor is fixedly mounted inside the fixed seat. A screw is mounted on the DC motor. The mounting seat is movably mounted on the screw. A ball bearing is rotatably mounted on the side of the mounting seat. The ball bearing contacts the inner wall of the mounting groove.

[0013] Optionally, a supplementary light and a vision component are fixedly installed on the fixing rod. The supplementary light is installed on both sides of the vision component, and the vision component includes a high-definition camera.

[0014] Optionally, the limiting block is movably installed inside the limiting groove, a limiting plate is welded to the top of the limiting block, a U-shaped groove is opened on the limiting plate, and the limiting plate is movably installed on the side of the movable plate.

[0015] Optionally, a support column is installed inside the U-shaped groove, a material roll is wound on the support column, and leather fabric is installed on the material roll. The leather fabric is movably mounted on the driving roller, driven roller, support roller, positioning roller, and movable roller.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. In this invention, the support plate on the rotating seat is tilted by the second power mechanism. When the support plate is tilted, it applies pressure to the surface of the leather fabric. After the leather fabric is deformed by the pressure, it is scraped by the support plate. During the scraping, impurities and loose hair on the surface of the leather fabric fall off. The impurities and loose hair are moved outward by the opening diversion. When they are moved outward, the suction generated by the exhaust pipe collects the impurities and loose hair into the inside of the fixed cylinder. In addition, the suction generated by the exhaust pipe facilitates the adsorption and discharge of the smoke that appears at the laser marking position. When the support plate is tilted, the leather fabric is pressed on the surface of the support roller. The tightness is adjusted by the deformation of the leather fabric, thereby providing a flat leather surface during marking. 2. In this invention, the movable seat is driven to move inside the support box by the first power mechanism. When the movable seat moves, the position of the marking point is changed. In addition, the movable seat and the laser emitting end are limited by the slotted and open positions. Under the push of the threaded column, the movable seat can move horizontally. The opening and slot are distributed vertically opposite each other. The smoke generated by laser marking can be quickly discharged outward through the opening and slot, thereby effectively avoiding the impact of smoke accumulation. When the support plate presses the leather fabric downward, the leather fabric moves to one side of the limiting seat. When the leather fabric moves, it drives the movable roller to move. The position of the support point of the leather fabric is reduced by the displacement of the movable roller. The flatness and width at the marking point position can be adjusted by adjusting the tightness of the leather fabric, thereby completing the marking of different sizes. 3. In this invention, the tightness of the leather fabric is adjusted twice by the up-and-down movement of the limiting seat. In addition, the up-and-down movement of the limiting seat moves the limiting plate between the movable plates. The movable plate covers both sides of the U-shaped groove and fixes the leather fabric by limiting it. Later, the downward movement of the limiting seat removes the cover of the U-shaped groove by the movable plate, which facilitates the replacement of materials later. In addition, the movable plate drives the limiting plate and the leather fabric to move left and right. The left and right movement of the leather fabric effectively avoids the impact of displacement. At the same time, the movable plate moves inward and outward, which can be used to position and install leather fabrics of different widths. 4. In this invention, the motor drives the threaded column to move the movable seat horizontally within the opening and slot. The rotational force of the threaded column allows the movable seat to move a small distance, thus finely adjusting the position of the marking point. In practical use, the support box provides a fixing force for the entire fixed cover, ensuring that the fixed cover is fixedly installed on top of the positioning roller and the movable roller. The fixed cover provides shielding for the marking point. There is a large gap between the support roller and the driven roller, providing the necessary space for the support plate to tilt at one end. The space between the support roller and the driven roller allows the leather fabric to be recessed later. Under the shielding, the smoke generated during marking is less affected by external airflow. The smoke can move upward through the opening and slot. In addition, the airflow during the movement of the movable seat carries the smoke from the marking point out, simultaneously cooling the marking point and preventing the leather fabric from being affected by prolonged high temperatures.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 9 As shown, a laser marking machine for leather includes: a base 1, a support seat 2 fixed to the top of the base 1, a fixed seat 3 welded to the bottom of the support seat 2, an active roller 5 and a support roller 24 rotatably mounted on the fixed seat 3, a driven roller installed between the support roller 24 and the active roller 5, a feeding assembly 4 movably mounted on one side of the support seat 2 and the fixed seat 3, and a fixed box 8 fixed to the top of the fixed seat 3; the feeding assembly 4 includes a limiting seat 46, a limiting groove 47 on the limiting seat 46, a reset mechanism 48 fixed inside the limiting groove 47, and a limiting block 49 fixed to one end of the reset mechanism 48; and a support assembly 15, including a support box 19, both ends of the support box 19 fixed to the inner wall of the fixed box 8, and a fixed cover 20 fixed to the bottom of the support box 19. A rotating seat 21 is movably installed on the side of the 20, and a support plate 22 is welded on the rotating seat 21. This application is applied to leather laser marking, and simultaneously deploys intelligent welding systems and intelligent heat treatment production lines, and mass-produces automatic and semi-automatic electric arc and plasma arc welding machines and other metal cutting and welding equipment. It empowers high-end manufacturing and material processing with intelligent and automated products. In use, the rolled leather fabric 18 is placed on the feeding assembly 4. One end of the leather fabric 18 is sequentially installed on the top of the active roller 5, driven roller, support roller 24, positioning roller 55 and movable roller 29. A limiting cylinder is installed on the side of the movable roller 29. After passing one end of the leather fabric 18 through the top of the movable roller 29, it is installed on the bottom of the limiting cylinder and pulled outward. An existing winding device is installed at one end of the fixed seat 3. The winding device completes the winding of the leather fabric 18 after marking.

[0022] In this embodiment, an exhaust assembly 23 is fixed on the support plate 22. The exhaust assembly 23 includes a mounting bracket, and an exhaust fan is fixed inside the mounting bracket. An air cavity 35 is opened inside the support plate 22. An opening 34 is opened on the side of the support plate 22 and is connected to the air cavity 35. A movable roller 29 and a positioning roller 55 are installed inside the fixed cover 20. A sliding groove 54 is opened on the inner wall of the fixed box 8. A slider 31 is movably installed inside the sliding groove 54. A support mechanism 33 is fixed on the slider 31. The slider 31 is movably installed inside the sliding groove 54 through the support mechanism 33. A damper 32 is fixedly installed on the slider 31. A rotating column 30 is rotatably mounted on the slider 31. One end of the rotating column 30 is fixed to the movable roller 29. An opening 25 is opened on the support box 19. A movable seat 26 is movably mounted inside the opening 25. A controller 28 is fixed on the top of the movable seat 26. A slot 36 is opened on the fixed cover 20.

[0023] It is understandable that the support mechanism 33 is a support spring. After the support spring is compressed, it generates a rebound force. The rebound force pushes the slider 31 back to its original position. With the cooperation of the support mechanism 33 and the damper 32, the slider 31 moves stably, thereby avoiding wrinkles and damage to the rapidly moving material. When the leather fabric 18 is pressed by the support plate 22, the leather fabric 18 moves as a whole. The overall movement of the leather fabric 18 drives the movable roller 29 to move to the positioning roller 55 through the slider 31. The movement of the movable roller 29 reduces the width of the support point on the leather fabric 18, thereby providing better multi-point support for the leather fabric 18 and ensuring the stability of the leather fabric 18 during marking under multi-point support.

[0024] In this embodiment, a laser emitter 37 is movably installed inside the slot 36. A threaded column 27 is rotatably installed on the movable seat 26. A first power mechanism 9 is fixed to one end of the threaded column 27. The first power mechanism 9 is fixedly installed on the fixed box 8. A second power mechanism 10 is installed on the fixed box 8. The second power mechanism 10 is connected to the positioning roller 55 through an output shaft. A fixed cylinder 16 is fixed to the side of the fixed box 8. An exhaust pipe 17 is fixedly installed between the fixed cylinders 16. A ventilation pipe 53 is fixed to one end of the fixed cylinder 16. The ventilation pipe 53 is fixedly installed inside the fixed box 8. A fixed frame 11 is fixed to the side of the fixed box 8. A fixed rod 12 is welded between the fixed frames 11. A drive motor 6 and a servo motor 7 are fixedly installed on the side of the fixed seat 3. A threaded rod 42 is installed on the drive motor 6. The threaded rod 42 is rotatably installed on the fixed block 39. The drive motor 6 is connected to the active roller 5. The fixed seat 3 has a fixed groove 38 on its side. A fixed block 39 is movably installed inside the fixed groove 38. A movable plate 52 is fixed to one end of the fixed block 39. The support seat 2 has an installation groove 40 on its side.

[0025] In this configuration, both the first power mechanism 9 and the second power mechanism 10 are existing motors. Driven by the motor, the threaded column 27 moves the movable seat 26 horizontally within the opening 25 and the slot 36. The rotational force of the threaded column 27 allows the movable seat 26 to move a small distance, thus finely adjusting the position of the marking point. In practical use, the support box 19 provides overall fixing force to the fixed cover 20, ensuring that the fixed cover 20 is fixedly installed on top of the positioning roller 55 and the movable roller 29. The fixed cover 20 provides shielding for the marking point. The support roller 24... There is a large gap between the support plate 22 and the driven roller, which provides the necessary space for one end of the support plate 22 to tilt. The leather fabric 18 is recessed in the later stage through the space between the support roller 24 and the driven roller. The smoke generated by marking under the cover is reduced by the influence of external airflow. The smoke can move upward through the opening 25 and the slot 36. In addition, the airflow is carried out as the movable seat 26 moves. The airflow carries the smoke from the marking point and cools the marking point at the same time, avoiding the impact of long-term high temperature on the leather fabric 18.

[0026] In this embodiment, a mounting base 41 is movably mounted inside the mounting groove 40. The mounting base 41 is welded to the side of the limiting seat 46. A DC motor 43 is fixedly mounted inside the fixed seat 3. A screw 44 is mounted on the DC motor 43. The mounting base 41 is movably mounted on the screw 44. A ball bearing 45 is rotatably mounted on the side of the mounting base 41, and the ball bearing 45 contacts the inner wall of the mounting groove 40. A supplementary light 13 and a vision component 14 are fixedly mounted on the fixed rod 12. The supplementary light 13 is mounted on both sides of the vision component 14, and the vision component 14 includes a high-definition camera. A limiting block 49 is movably mounted inside the limiting groove 47. A limiting plate 50 is welded to the top of the limiting block 49. A U-shaped groove 51 is opened on the limiting plate 50, and the limiting plate 50 is movably mounted on the side of the movable plate 52. The U-shaped groove 51 is equipped with a support column, on which a material roll is wound. The material roll is equipped with leather fabric 18, which is movably mounted on the driving roller 5, the driven roller, the support roller 24, the positioning roller 55, and the movable roller 29.

[0027] It should be noted that during use, the support plate 22 tilts under the drive of the rotating seat 21. The tilted support plate 22 cleans the surface of the leather fabric 18 by scraping. During this cleaning process, the exhaust assembly 23 generates airflow, which is guided through the air chamber 35 to the interior of the opening 34. Impurities are blown outwards through the opening 25. Additionally, the airflow at the opening 34 cools the support plate 22 itself, as prolonged pressure and friction between the support plate 22 and the leather fabric 18 generates high temperatures. If these high temperatures cannot be removed, they can easily damage the leather fabric 18. The airflow through the opening 34 simultaneously cools the support plate 22, thus completing the prolonged friction cleaning of the leather fabric 18. Driven by the drive motor 6, the thread... When rod 42 rotates, the threaded rod 42 drives the fixed block 39 to move horizontally inside the fixed groove 38. The fixed groove 38 provides a limiting force for the fixed block 39. Under the limiting force, the fixed block 39 moves horizontally inside the fixed groove 38. As the fixed block 39 moves horizontally, the movable plate 52 moves inward and outward at the same time. The inward and outward movement of the movable plate 52 can push the limiting plate 50. Under the push of the limiting plate 50, the limiting block 49 moves inside the limiting groove 47. The movement of the limiting block 49 completes the compression of the reset mechanism 48. The reset mechanism 48 is a reset spring. After the limiting plate 50 loses compression, the reset spring returns to its original position. The left and right movement of the limiting plate 50 adjusts the position of the leather fabric 18, thereby effectively avoiding the impact caused by the displacement of the leather fabric 18.

[0028] Working principle: During use, the DC motor 43 is started to drive the screw 44 to rotate. The rotation of the screw 44 causes the mounting base 41 to move vertically up and down inside the mounting groove 40. Driven by the mounting base 41, the limiting seat 46 moves downwards. After the limiting seat 46 moves downwards, the limiting plate 50 and the movable plate 52 separate, and one side of the U-shaped groove 51 is no longer obstructed. The U-shaped groove 51 descends, and the roll of material with leather fabric 18 is installed inside the U-shaped groove 51 via the support column. After the material is installed, the DC motor 43 is started again to drive the screw 44 to rotate. The screw 44 rotates in the opposite direction, causing the mounting base 41 to move upwards. After the mounting base 41 moves upwards, the limiting plate 50 is installed on the inner wall of the movable plate 52. The movable plate 52 limits the two ends of the support column. When the widths of the leather fabric 18 are different, the servo motor 7 is activated first to drive the threaded rod 42 to rotate. The threaded rod 42 drives the fixed block 39 and the movable plate 52 to move inward. After the movable plate 52 moves inward, it adjusts the width of the limit plate 50. Leather fabrics 18 of different widths are installed on the limit plate 50 and fixed at the upper limit. After the leather fabric 18 is installed, one end of the leather fabric 18 is sequentially installed on the active roller 5, driven roller, support roller 24, positioning roller 55 and movable roller 29. A limit cylinder is installed on the side of the movable roller 29. One end of the leather fabric 18 is pulled outward after passing through the top of the movable roller 29 and then installed on the bottom of the limit cylinder. The existing winding equipment is installed at one end of the fixed seat 3. The winding equipment completes the marking process. During the laser marking process, when the tightness of the leather fabric 18 needs to be adjusted during the winding of the leather fabric 18, the second power mechanism 10 is activated to drive the rotating seat 21 to rotate. The support plate 22 tilts under the influence of the rotating seat 21, and the tilting of the support plate 22 completes the scraping and cleaning of the surface of the leather fabric 18. During this scraping and cleaning, the exhaust component 23 generates airflow, which is guided through the air cavity 35 to the interior of the opening 34. Impurities are blown outward through the opening 34. Additionally, the airflow at the opening 34, after flowing over the support plate 22, can cool the support plate 22 itself. This is because the support plate 22 and the leather fabric 18 generate high temperatures during prolonged pressure and friction, and if these high temperatures cannot be removed, they can easily damage the leather fabric 18. The airflow blowing out through the opening 24 simultaneously... The cooling of the paired support plates 22 completes the long-term friction cleaning of the leather fabric 18. Driven by the drive motor 6, the threaded rod 42 rotates, which drives the fixed block 39 to move horizontally inside the fixed groove 38. The fixed groove 38 provides a limiting force for the fixed block 39. Under the limiting force, the fixed block 39 moves horizontally inside the fixed groove 38. As the fixed block 39 moves horizontally, the movable plate 50 moves inward and outward at the same time. The inward and outward movement of the movable plate 50 can push the limiting plate 50. Under the pushing, the limiting plate 50 moves through the limiting block 49 inside the limiting groove 47. The movement of the limiting block 49 completes the compression of the reset mechanism 48. The reset mechanism 48 is a reset spring. After the limiting plate 50 loses compression, the reset spring returns to its original position.The left and right movement of the limiting plate 50 adjusts the position of the leather fabric 18, thereby effectively preventing the leather fabric 18 from shifting and causing adverse effects. In practical use, the support box 19 provides a fixing force for the fixed cover 20, so that the fixed cover 20 is fixedly installed on the top of the positioning roller 55 and the movable roller 29. The fixed cover 20 provides shielding for the marking point. Under the shielding, the smoke generated during marking is reduced from the influence of external airflow. The smoke can move upward through the opening 25 and the slot 36. In addition, the airflow moves the movable seat 36, which carries the smoke from the marking point out, thus cooling the marking point and preventing the leather fabric 18 from being affected by prolonged high temperature. When the leather fabric 18 is pressed by the support plate 22, the leather fabric 18 moves as a whole, and the movement of the leather fabric 18 drives the movable roller. 29 moves towards the positioning roller 55 via the slider 31. The movement of the movable roller 29 reduces the width of the support point on the leather fabric 18, thereby providing better multi-point support for the leather fabric 18. Under multi-point support, the stability of the leather fabric 18 during marking is ensured. Later, the DC motor 42 drives the mounting base 41 and the limiting seat 46 to move up and down. The up and down movement of the limiting seat 46 can also make secondary adjustments to the tightness. When the support plate 22 presses the leather fabric 18, there is a large gap between the support roller 24 and the driven roller. The gap provides the necessary space for one end of the support plate 22 to tilt. The space between the support roller 24 and the driven roller allows the leather fabric 18 to be indented later.
