Description

Technical Field

[0001] The invention relates to the technical field of embossing roller etching, in particular to a composite etching device with dual processing functions of electric engraving and laser direct engraving. Background Art

[0002] This electro-etching equipment utilizes CNC and laser technology, creating precise cell-like patterns by irradiating the copper roller surface with laser light to produce physical modifications. Equipped with an automated clamping system and a mechanical clamping mechanism to prevent loosening over time, combined with precision surface treatment processes (such as a gear-driven polishing pad array), it can continuously polish rollers with diameters ranging from 600 to 1200 mm. Key specifications include a polishing accuracy of 0.2-1.5 μm, cell depth controlled by laser pulse frequency, and CNC vector path engraving capabilities. This equipment is suitable for producing high-precision cell patterns of 150-200 lines per inch on cigarette packaging and shallow cell structures of 250-300 μm on food packaging.

[0003] An engraving device is required when producing embossing rollers, such as a copper-plated steel roller surface embossing laser engraving device and an embossing roller manufacturing method with patent publication number CN119658118A, which includes a base plate, multiple fixing frames arranged on the side walls of the base plate, support plates arranged on two corresponding fixing frames, and an engraving unit arranged on the support plate, wherein the engraving unit includes a cleaning component and an engraving component arranged between the two support plates. For example, the patent publication number CN213163654U is a dust-proof high-precision embossing roller engraving machine, which includes an engraving table, a dust-proof box, an embossing roller adjustable clamping device, a particle filter, a dust removal and heat dissipation device, an observation plate fixing part, an engraving observation plate, an engraving hinged door and an exhaust box. The embossing roller adjustable clamping device is arranged on the engraving table, the dust removal and heat dissipation device is arranged on the dust-proof box, and the exhaust box is arranged on the dust removal and heat dissipation device. The dust removal and heat dissipation device includes a dust removal box, a dust removal hole, a dust removal motor, a motor bracket, an exhaust fan, an exhaust hole and a partition baffle, which overcomes the problem of dust accumulation greatly reducing the accuracy during engraving. It is a very practical dust-proof high-precision embossing roller engraving machine.

[0004] The above two devices etch the surface of the embossing roller through laser engraving and electric engraving respectively. The functional ranges of laser engraving and electric engraving are different. Laser direct engraving is suitable for high-precision micro-engraving, while electric engraving is suitable for large-scale and rapid processing of simple patterns. However, different patterns may need to be engraved at different positions of the embossing roller. Therefore, the engraving requirements at different positions are different. Using only one engraving method will reduce the overall engraving quality and efficiency. Summary of the Invention

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-13 As shown, the present invention provides a technical solution: a composite etching device with dual processing functions of electric engraving and laser direct engraving, comprising a base 1, two symmetrically distributed brackets 2 are provided on the base 1, and a fixing mechanism for fixing the embossing roller is provided on the bracket 2, and an upper end of the bracket 2 is fixed with a raising frame 3, and a screw 4 and a guide rod 5 are fixed between the two raising frames 3, two screw motors 6 are installed on the screw 4, and two guide sleeves 7 are slidably provided on the guide rod 5, a moving ring 8 is fixed under one of the screw motors 6 and the guide sleeve 7, a circular slide rail 9 is provided on the side of the moving ring 8, a first driving mechanism is provided on the circular slide rail 9, and a carving knife 10 is provided on the first driving mechanism, a moving plate 11 is fixed under the other screw motor 6 and the guide sleeve 7, a second driving mechanism is provided on the moving plate 11, a laser head 12 is provided on the second driving mechanism, and a dust removal mechanism is provided on the side of the moving ring 8 close to the moving plate 11.

[0024] It should be noted that the embossing roller is fixed between the two brackets 2 by a fixing mechanism and driven to rotate. The movable ring 8 and the movable plate 11 are respectively driven to move by two screw motors 6. The movable plate 11 drives the laser head 12 to move along the axial direction of the embossing roller. The movable ring 8 drives the engraving tool 10 to move along the axial direction of the embossing roller. At the same time, the surface engraving of the embossing roller is realized by cooperating with the rotation of the embossing roller. Moreover, laser direct engraving and electric engraving are carried out simultaneously (first electric engraving long lines, then laser direct engraving lines, and at the same time electric engraving follows the laser direct engraving to deepen or expand specific parts of the pattern). They can also be carried out in a distributed manner. Moreover, the engraving tool 10 can rotate along the movable ring 8 under the drive of the first driving mechanism, so that the laser head 12 and the engraving tool 10 are not limited to moving in the same straight line, and can adapt to the different speeds of electric engraving and laser direct engraving.

[0025] like Figure 4 As shown, the first driving mechanism includes a sliding sleeve 13 slidably set on the circular slide rail 9, a first rodless cylinder 14 is fixed on the sliding sleeve 13, a first mounting plate 15 is fixed on the moving part of the first rodless cylinder 14, an engraving motor 16 is mounted on the first mounting plate 15, and the engraving tool 10 is mounted on the output shaft of the engraving motor 16, a motor frame 17 is fixed to the outside of the sliding sleeve 13, a rotating motor 18 is mounted on the motor frame 17, and a driving gear is mounted on the output shaft of the rotating motor 18, an outer gear ring is provided on the outer side of the movable ring 8, and the driving gear and the outer gear ring are meshed.

[0026] It should be noted that by rotating the driving gear through the rotating motor 18, the sliding sleeve 13 can be controlled to move on the circular slide rail 9, and the engraving motor 16 can provide rotational power for the engraving knife 10 to achieve the engraving effect. At the same time, the first rodless cylinder 14 can drive the first mounting plate 15 to move up and down to achieve the height adjustment of the engraving knife 10 and adapt to embossing rollers of different diameters.

[0027] like Figure 5 As shown, the second driving mechanism includes a second rodless cylinder 19 fixed to the side end of the movable plate 11 , a second mounting plate 20 is fixed to the movable part of the second rodless cylinder 19 , and the laser head 12 is mounted on the second mounting plate 20 .

[0028] It should be noted that the second rodless cylinder 19 can drive the second mounting plate 20 to move up and down, thereby realizing the height adjustment of the laser head 12, and can adjust the distance between the laser head 12 and the surface of the embossing roller, thereby improving the effect of laser direct engraving, and can adapt to embossing rollers of different diameters.

[0029] like Figure 2 、 Figure 6 and Figure 7As shown, the fixing mechanism includes a rotating disk 21 rotatably arranged on the bracket 2, one of the rotating disks 21 is fixed with three clamping rods 22, and the other rotating disk 21 is slidably arranged with three clamping rods 22, and the ends of the three sliding clamping rods 22 are fixed with a fixing plate 23, and an electric push rod 24 is installed between the fixing plate 23 and the rotating disk 21, a driving motor 25 is installed on the base 1, and the driving motor 25 drives one of the rotating disks 21 to rotate through a belt transmission pair, and inner curved rods 26 are rotatably arranged on both sides of the end of the clamping rod 22, and a long slot 27 is opened on the inner curved rod 26, a top plate 28 is provided between the clamping rods 22, and three square holes 29 are opened on the top plate 28, the clamping rod 22 passes through the square holes 29 at corresponding positions, and side grooves 30 are opened on both sides of the square hole 29, the inner curved rod 26 passes through the side groove 30, and a fixing block 31 is provided on the inner wall of the side groove 30, and the fixing block 31 is slidably set in the long slot 27 at the corresponding position.

[0030] It should be noted that when in use, the central axis of the embossing roller is placed in the middle of the clamping rod 22, and then the clamping rod 22 at one end is close to the central axis under the action of the electric push rod 24. At this time, the two ends of the central axis are respectively against the two top plates 28. As the clamping rod 22 is squeezed, the central axis squeezes the two top plates 28 to both sides. At this time, the fixed block 31 will slide in the long slot 27, forcing the inner bending rod 26 to start rotating. At this time, the ends of multiple inner bending rods 26 will be clamped on the outside of the central axis, achieving the effect of fixing the embossing roller, and being able to position the central axis of the embossing roller.

[0031] like Figure 7 As shown, a driven magnetic block 32 is fixed to the side of the top plate 28 .

[0032] It should be noted that the central axis of the embossing roller is mostly made of magnetic material (iron). When the embossing roller is removed, the clamping rod 22 is separated to both sides. At this time, the top plate 28 will move along the end of the central axis under the action of the suction force between the driven magnetic block 32 and the central axis, making it convenient for the inner bending rod 26 to unfold and prevent the device from getting stuck.

[0033] like Figure 8 As shown, the dust removal mechanism includes an annular air cavity 33 fixed on the side of the movable ring 8, and an annular rotating cover 34 is rotatably provided on the side of the annular air cavity 33 close to the engraving knife 10, a suction pipe 35 is provided at the upper end of the annular air cavity 33, and a connecting plate 36 is fixed to the back of the annular rotating cover 34 and the first rodless cylinder 14, a dust suction pipe 37 is connected to the annular rotating cover 34, a smoking pipe 38 is connected to the side end of the annular air cavity 33, and a suction hood 39 is provided below the smoking pipe 38.

[0034] It should be noted that the suction pipe 35 is connected to the external dust collection device to provide negative pressure inside the annular air cavity 33. At this time, the dust generated by the engraving tool 10 will be sucked into the annular air cavity 33 through the dust collection pipe 37. Similarly, the smoke and dust generated by the laser head 12 during engraving will enter the annular air cavity 33 through the suction hood 39 and the smoking pipe 38, and finally be discharged through the suction pipe 35. Moreover, when the engraving tool 10 rotates along the circular slide rail 9, the annular rotating cover 34 moves synchronously with the first rodless cylinder 14 under the action of the connecting plate 36, ensuring that the dust collection pipe 37 is always facing the engraving tool 10.

[0035] like Figure 10 and Figure 11 As shown, the dust suction tube 37 is a hose, and a first covering cover 40 is provided on the outer side of the dust suction tube 37, and the first covering cover 40 is made of iron material. A first positioning magnet 41 is provided at the lower end of the first rodless cylinder 14, and the first positioning magnet 41 is adsorbed on the upper surface of the first covering cover 40. A push rod 42 is fixed to the back side of the first mounting plate 15, and a first follower magnet 43 is fixed to the lower end of the push rod 42, and the lower end of the first follower magnet 43 is adsorbed on the upper surface of the first covering cover 40.

[0036] It should be noted that when the diameter of the embossing roller is small, the first rodless cylinder 14 will drive the first mounting plate 15 to move downward. At this time, the push rod 42 will push the opening of the dust suction tube 37 to deviate downward, and will not fall under the magnetic force of the first follower magnet 43 and the first covering cover 40. It can be further close to the engraving position of the engraving knife 10, thereby improving the dust removal effect. Moreover, when the engraving knife 10 is lifted upward, the end of the dust suction tube 37 will be attached to the lower surface of the first positioning magnet 41 and will not fall downward.

[0037] like Figure 4 and Figure 9 As shown, two symmetrically distributed cross bars 44 are fixed to the lower end of the first rodless cylinder 14, a circular hole 45 is opened on the cross bar 44, a sleeve 46 is rotatably set in the circular hole 45, a cover plate 47 is fixed on the outside of the sleeve 46, a lifting rod 49 is inserted in the sleeve 46, an oblique slot 48 is opened on the side wall of the sleeve 46, a slider 50 is fixed on the lifting rod 49, and the slider 50 is located in the oblique slot 48, and a lifting plate 51 is fixed to the upper end of the lifting rod 49.

[0038] It should be noted that when only laser direct engraving is used, the first rodless cylinder 14 will drive the first mounting plate 15 to move upward. At this time, the first mounting plate 15 will push the lifting plate 51 upward, and the lifting rod 49 will move upward. Under the action of the inclined slot 48 and the slider 50, the cover plate 47 will rotate to a certain angle and fit into the port of the dust suction pipe 37 to achieve a blocking effect and improve the smoking effect of the smoking pipe 38 on the other side. When the first mounting plate 15 descends, the lifting plate 51 and the lifting rod 49 will descend under the action of gravity, driving the cover plate 47 to reset and open the port of the dust suction pipe 37.

[0039] like Figure 10 and Figure 12 As shown, a fixed sleeve 52 with a sealed end is fixed to the outside of the annular air cavity 33, and an extrusion rod 54 is slidably provided on the sealed end of the fixed sleeve 52. A retaining ring 53 is fixed to the inside of the fixed sleeve 52, and a baffle 55 is fixed to the end of the extrusion rod 54. The baffle 55 and the side of the retaining ring 53 close to the annular air cavity 33 are abutted, and a compression spring 56 is provided between the baffle 55 and the annular air cavity 33. The end of the smoking pipe 38 is connected to the fixed sleeve 52, and the smoking pipe 38 is located on the side of the retaining ring 53 away from the annular air cavity 33. A through hole 57 is opened on the annular air cavity 33, and the through hole 57 is aligned with the extrusion rod 54.

[0040] It should be noted that when only electric engraving is performed, the movable plate 11 can be moved to the outermost position. At this time, the movable plate 11 is separated from the squeezing rod 54, and the compression spring 56 will press the baffle 55 against the baffle ring 53 to achieve the blocking of the smoking pipe 38 and increase the suction force of the dust suction pipe 37 on the other side. When electric engraving and laser direct engraving are performed at the same time, the movable plate 11 approaches and presses against the squeezing rod 54, so that the baffle 55 is separated from the baffle ring 53. At this time, the smoking pipe 38 and the annular air cavity 33 are connected, and the smoke exhaust effect can be achieved.

[0041] like Figure 10 and Figure 13 As shown, the smoking pipe 38 is a hose, and a bent plate 59 is fixed under the extrusion rod 54. A second positioning magnet 60 is fixed to the lower end of the bent plate 59. A second covering cover 58 is provided on the outer side of the smoking pipe 38, and the second covering cover 58 is made of iron material. The lower surface of the second positioning magnet 60 is adsorbed on the upper surface of the second covering cover 58. A second following magnet 61 is fixed to the lower end of the second mounting plate 20, and the second following magnet 61 is adsorbed on the upper surface of the second covering cover 58.

[0042] It should be noted that the second positioning magnet 60 on the bent plate 59 can absorb the second covering cover 58 to prevent the end of the smoking pipe 38 from falling, and when the diameter of the embossing roller is small, the second rodless cylinder 19 will drive the second mounting plate 20 to move downward. At this time, the second mounting plate 20 will push the open end of the smoking pipe 38 to deflect downward, and will not fall under the magnetic force of the second follower magnet 61 and the second covering cover 58, and can be further close to the engraving position of the laser head 12 to improve the dust removal effect.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
