Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of embossing roller etching, in particular to a composite etching equipment with double processing functions of electrography and laser direct carving. BACKGROUND

[0002] The electrography etching equipment takes numerical control and laser technology as the core, realizes precise mesh hole carving by physical denaturation generated by laser irradiation on the surface of the copper roller. The equipment is equipped with an automatic clamping system, adopts a mechanical clamping structure to prevent loosening during long-term use, and is combined with a precise surface treatment process (such as a gear-driven polishing sheet array) to continuously polish a roller body with a diameter of 600-1200mm. The core parameters include a polishing precision of 0.2-1.5μm, a laser pulse frequency control mesh hole depth, and a numerical control vector path carving capability, which are suitable for processing high-precision mesh patterns of 150-200 lines / inch for cigarette packages and shallow mesh hole structures of 250-300μm for food packaging.

[0003] When producing embossing rollers, engraving devices need to be used. For example, a copper-plated steel roller surface embossing laser engraving equipment and embossing roller manufacturing method disclosed in patent publication No. CN119658118A includes a bottom plate, a plurality of fixing frames arranged on the side wall of the bottom plate, a support plate arranged on the corresponding two fixing frames, and an engraving unit arranged on the support plate. The engraving unit includes a cleaning component and an engraving component arranged between the two support plates. For example, a dustproof high-precision embossing roller engraving machine disclosed in patent publication No. CN213163654U includes an engraving table, a dustproof box, an embossing roller adjusting type clamping device, a particle filter screen, a dust removal and heat dissipation device, an observation plate fixing piece, an engraving observation plate, an engraving hinged door, and an exhaust box. The embossing roller adjusting type clamping device is arranged on the engraving table. The dust removal and heat dissipation device is arranged on the dustproof box. 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 support, a suction fan, an exhaust hole, and a partition baffle. The problem of greatly reduced precision due to dust accumulation during engraving is overcome. It is a very practical dustproof high-precision embossing roller engraving machine.

[0004] The above two devices respectively perform etching on the surface of the embossing roller through laser engraving and electrography. The functional ranges of laser engraving and electrography are different. Laser direct carving is suitable for high-precision micro carving, and electrography is suitable for rapid processing of large quantities 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. Simply using one type of engraving method will reduce the overall engraving quality and engraving efficiency. SUMMARY

[0042] As Figure 2 , Figure 6 and Figure 7 shown, the fixing mechanism includes a rotating disc 21 rotatably arranged on the support 2, one of the rotating discs 21 is fixed with three clamping rods 22, the other rotating disc 21 is slidably arranged with three clamping rods 22, the end of the three clamping rods 22 arranged in sliding mode is fixed with a fixing plate 23, an electric push rod 24 is mounted between the fixing plate 23 and the rotating disc 21, a driving motor 25 is mounted on the base 1, and the driving motor 25 drives one of the rotating discs 21 to rotate through a belt transmission pair, the end of the clamping rod 22 is rotatably arranged with an inner bent rod 26, a long slot 27 is formed in the inner bent rod 26, a top plate 28 is arranged between the clamping rods 22, three square holes 29 are formed in the top plate 28, the clamping rod 22 passes through the square hole 29 at the corresponding position, a side slot 30 is formed at both sides of the square hole 29, the inner bent rod 26 passes through the side slot 30, and a fixing block 31 is arranged on the inner wall of the side slot 30.

[0043] It should be noted that in use, the center shaft of the embossing roller is placed in the middle of the clamping rod 22, and then one end of the clamping rod 22 is close to the center shaft under the action of the electric push rod 24, at this time the two ends of the center shaft are respectively abutted with the two top plates 28, and with the extrusion of the clamping rod 22, the center shaft extrudes the two top plates 28 to the two sides, at this time the fixing block 31 will slide in the long slot 27, forcing the inner bent rod 26 to start rotating, at this time the end of the plurality of inner bent rods 26 will be clamped outside the center shaft, realizing the effect of fixing the embossing roller, and the center axis of the embossing roller can be positioned.

[0044] As Figure 7 shown, the side of the top plate 28 is fixed with a driven magnetic block 32.

[0045] It should be noted that the center shaft of the embossing roller is mostly made of magnetic material (iron), when the embossing roller is removed, the clamping rod 22 separates to the two sides, at this time the top plate 28 will move in close contact with the end of the center shaft under the action of the attraction between the driven magnetic block 32 and the center shaft, facilitating the unfolding of the inner bent rod 26, and preventing the device from being stuck.

[0046] As Figure 8 shown, the dust removal mechanism includes a ring-shaped air cavity 33 fixed on the side of the moving ring 8, and the ring-shaped air cavity 33 is provided with a ring-shaped rotating cover 34 on the side close to the carving knife 10, the upper end of the ring-shaped air cavity 33 is provided with a suction pipe 35, the ring-shaped rotating cover 34 is fixed with a connecting plate 36 on the back of the first rodless cylinder 14, the ring-shaped rotating cover 34 is connected with a dust suction pipe 37, the side end of the ring-shaped air cavity 33 is connected with a smoke suction pipe 38, and the lower side of the smoke suction pipe 38 is provided with a smoke suction cover 39.

[0047] It should be noted that the suction pipe 35 is connected with the external dust suction equipment, and negative pressure is provided in the ring-shaped air cavity 33, at this time the dust generated by the carving knife 10 will be sucked into the ring-shaped air cavity 33 through the dust suction pipe 37, and the smoke generated by the laser head 12 will enter the ring-shaped air cavity 33 through the smoke suction cover 39 and the smoke suction pipe 38, and finally be discharged through the suction pipe 35, and when the carving knife 10 rotates along the circular slide rail 9, the ring-shaped rotating cover 34 moves synchronously with the first rodless cylinder 14 under the action of the connecting plate 36, ensuring that the dust suction pipe 37 is always directed towards the carving knife 10.

[0048] As Figure 10 and Figure 11 shown, the dust suction pipe 37 is a flexible pipe, the outer side of the dust suction pipe 37 is sleeved with a first cover 40, and the first cover 40 is made of iron material, the lower end of the first rodless cylinder 14 is provided with a first positioning magnetic block 41, the first positioning magnetic block 41 is adsorbed on the upper surface of the first cover 40, the back of the first mounting plate 15 is fixed with a top rod 42, the lower end of the top rod 42 is fixed with a first following magnetic block 43, and the lower end of the first following magnetic block 43 is adsorbed on the upper surface of the first cover 40.

[0049] 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 top rod 42 will push the opening of the dust suction pipe 37 to shift downward, and under the magnetic force action of the first following magnetic block 43 and the first cover 40, it will not fall downward, and can further approach the carving position of the carving knife 10, improving the dust removal effect, and when the carving knife 10 is lifted upward, the end of the dust suction pipe 37 will be attached to the lower surface of the first positioning magnetic block 41, and will not fall downward.

[0050] As Figure 4 and Figure 9 shown, the lower end of the first rodless cylinder 14 is fixed with two symmetrical horizontal rods 44, the horizontal rods 44 are provided with a circular hole 45, a sleeve 46 is rotatably arranged in the circular hole 45, a cover plate 47 is fixed on the outer side of the sleeve 46, a lifting rod 49 is inserted into the sleeve 46, a slanted slot 48 is formed in the side wall of the sleeve 46, a sliding block 50 is fixed on the lifting rod 49 and located in the slanted slot 48, and a lifting plate 51 is fixed on the upper end of the lifting rod 49.

[0051] It should be noted that when only laser direct carving is used, the first rodless cylinder 14 will drive the first mounting plate 15 to move upwards, at this time the first mounting plate 15 will push the lifting plate 51 upwards, and the lifting rod 49 will move upwards, under the action of the inclined slot 48 and the sliding block 50, the cover plate 47 will rotate by a certain angle and fit on the port of the dust suction pipe 37, realizing the plugging effect and improving the smoke suction effect of the other side smoke suction pipe 38. 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 opening the port of the dust suction pipe 37.

[0052] As shown in Figure 10 and Figure 12 , the outer side of the annular air cavity 33 is fixed with a fixed sleeve 52 with one end sealed, and the sealed end of the fixed sleeve 52 is slidably provided with an extrusion rod 54. The inside of the fixed sleeve 52 is fixed with a blocking ring 53, and the end of the extrusion rod 54 is fixed with a baffle 55. The baffle 55 abuts against the side of the blocking ring 53 close to the annular air cavity 33, and a compression spring 56 is arranged between the baffle 55 and the annular air cavity 33. The end of the smoke suction pipe 38 is connected to the fixed sleeve 52, and the smoke suction pipe 38 is located on the side of the blocking ring 53 away from the annular air cavity 33. A through hole 57 is formed in the annular air cavity 33, and the through hole 57 is aligned with the extrusion rod 54.

[0053] It should be noted that when only electrography is performed, the moving plate 11 can be moved to the edge position, at this time the moving plate 11 is separated from the extrusion rod 54, and the compression spring 56 abuts against the baffle 55 on the blocking ring 53 to realize the plugging of the smoke suction pipe 38 and improve the suction of the other side dust suction pipe 37. When electrography and laser direct carving are performed at the same time, the moving plate 11 is close to and abuts against the extrusion rod 54, so that the baffle 55 is separated from the blocking ring 53, at this time the smoke suction pipe 38 is in communication with the annular air cavity 33, that is, the smoke exhaust effect can be realized.

[0054] As shown in Figure 10 and Figure 13 , the smoke suction pipe 38 is a flexible pipe, the extrusion rod 54 is fixed below the baffle 59, the lower end of the baffle 59 is fixed with a second positioning magnetic block 60, the outer side of the smoke suction pipe 38 is provided with a second covering cover 58, and the second covering cover 58 is made of iron material.

[0055] It should be noted that the second positioning magnetic block 60 on the bending plate 59 can adsorb the second cover 58, preventing 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 offset downward, and under the magnetic force of the second following magnetic block 61 and the second cover 58, it will not fall, and can further approach the carving position of the laser head 12, improving the dust removal effect.
