Description

Technical Field

[0001] The present application relates to the technical field of laser engraving, and in particular to an embossing roller laser engraving device. Background Art

[0002] Embossing roller is an industrial equipment widely used in various industries. It mainly forms specific patterns or textures on the surface of materials through rolling, pressing, extrusion or engraving processes. Laser engraving is an advanced processing technology. It uses CNC technology as the basis and laser as the processing medium. Through the action of laser beam on the surface of the material, the material is instantly melted and vaporized, so as to achieve the purpose of engraving, cutting or marking. Preparing specific patterns or textures on the surface of embossing rollers through laser engraving devices is one of the many methods of processing embossing rollers.

[0003] For example, the patent with authorization announcement number CN215432059U discloses a laser engraving machine for embossing roller engraving, which includes a main body, a servo drive mechanism, a laser engraving head, a rotating fixed clamp mechanism, and a cleaning and dust removal mechanism and an embossing roller body. The staff clamps the embossing roller through the rotating fixed clamp mechanism, and then starts the servo drive mechanism to drive the laser engraving head to engrave the embossing roller. After the laser engraving is completed, the dust on the surface of the embossing roller body can be cleaned by rubbing the cleaning brush against the surface of the embossing roller body and spraying high-pressure airflow.

[0004] Although the above-mentioned device realizes the laser engraving operation on the embossing roller, and the surface of the embossing roller can be cleaned by the cleaning and dust removal mechanism after the engraving is completed, since the embossing roller is an industrial equipment, it is usually produced in batches.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] Embodiment 1: This embodiment mainly describes the basic structure and working principle of the embossing roller laser engraving device, specifically:

[0036] like Figure 1-Figure 2 As shown, the present application provides an embossing roller laser engraving device, including a base 1, which is the supporting part of the embossing roller laser engraving device, and is welded by multiple sets of steel frames. Usually, the base 1 is placed on a flat bottom surface to ensure the stable performance of the laser engraving operation;

[0037] An engraving device 2 for laser engraving the embossing roller is fixedly mounted on one side of the base 1. The engraving device 2 includes a support 21 fixedly mounted on the base 1, a first slide bar 22 is fixedly mounted on both sides of the support 21, and a first slider 23 is slidably mounted on the surface of the first slide bar 22. When subjected to an external force, the first slider 23 is suitable for sliding along the first slide bar 22;

[0038] A bracket 24 is fixedly mounted on the first slider 23, and a second slider 25 is fixedly mounted on the inner side of the bracket 24. A second slider 26 is slidably mounted on the surface of the second slider 25. When the second slider 26 is subjected to an external force, it is suitable for sliding along the second slider 25. A laser engraving member 27 is fixedly mounted on the second slider 26. The laser engraving member 27 is an existing laser engraving head.

[0039] In this embodiment, a PLC control system is installed in the support 21 to control the laser engraving part 27 to perform engraving operations. At the same time, the PLC control system is connected to the second slider 26 and the first slider 23 by signal. When the laser engraving part 27 is working, the PLC control system can pre-edit the program, and drive the laser engraving part 27 to move by controlling the first slider 23 and the second slider 26, and adjust the position of the laser engraving part 27, so as to perform laser engraving on different positions of the embossing roller;

[0040] A clamping device 4 is fixedly installed on the other side of the base 1, and the clamping device 4 includes a first support member 41 fixedly installed on the base 1, and at least two groups of second support members 42 are also fixedly installed on the base 1, and the second support member 42 is composed of a vertical steel pipe welded on the base 1 and a roller fixedly installed on the vertical steel pipe. At the same time, a first clamping disk 44 is arranged on the second support member 42, and the surface of the first clamping disk 44 is in friction contact with the roller, and a driving motor 43 is installed on one side of the first clamping disk 44, and the bottom of the driving motor 43 is fixedly connected to the top of the first support member 41, and the driving motor 43 is mainly used to drive the first clamping disk 44 to rotate, and the first clamping disk 44 is mainly used to clamp one side of the embossing roller and drive it to rotate, and how to achieve clamping is described below;

[0041] Continue to refer Figure 2 A three-jaw chuck 411 is connected to the first clamping plate 44 on one side away from the driving motor 43 through a bearing. The three-jaw chuck 411 is a prior art, and has a clamping end for clamping the embossing roller. The clamping end is composed of multiple groups of single jaws. The clamping end is clamped or relaxed through a PLC control system, and in the relaxed state, the gaps between the multiple groups of single jaws are large, so that it is convenient to disassemble the embossing roller after the processing is completed. The three-jaw chuck 411 clamps the embossing roller on one side of the three-jaw chuck 411. Roller 5, the embossing roller 5 is the existing embossing roller to be engraved. It should be noted that the first clamping disc 44 is hollow inside, and a driving device is installed in the first clamping disc 44. The output end of the driving device is connected to the three-jaw chuck 411. In the present application, the driving device can be a motor wheel combination or a hydraulic motor gear combination. When the driving device is started, it is suitable for driving the three-jaw chuck 411 to rotate, so as to drive the embossing roller 5 clamped by the three-jaw chuck 411 to rotate synchronously;

[0042] In order to clamp the other end of the embossing roller 5, Figure 1As shown, a third support member 45 is fixedly installed on the side of the base 1 away from the first support member 41, a second clamping plate 46 is fixedly installed on the third support member 45, a first cylinder 49 is fixedly installed on the second clamping plate 46, a resisting member 410 is fixedly installed on the output end of the first cylinder 49, and a resisting hole adapted to the resisting member 410 is opened on the other end of the embossing roller 5, and the resisting member 410 and the center end of the three-jaw chuck 411 are on the same axis. It should be noted that before the embossing roller 5 is engraved, a center hole needs to be opened on one end of the embossing roller 5 for The embossing roller 5 is positioned. In this embodiment, the abutting hole is the center hole. After one end of the embossing roller 5 is initially positioned by the three-jaw chuck 411, the staff can start the first cylinder 49. The output end of the first cylinder 49 drives the abutting member 410 to move. The abutting member 410 moves toward the position of the embossing roller 5 and finally abuts against the abutting hole to complete the clamping of the embossing roller 5. Since the abutting member 410 and the center end of the three-jaw chuck 411 are on the same axis, the embossing roller 5 can be clamped while keeping it in a horizontal state, which is convenient for subsequent engraving processing.

[0043] In summary, when performing the embossing roller laser engraving operation, the staff first moves the embossing roller 5 between the first clamping plate 44 and the second clamping plate 46 by using an auxiliary tool, and aligns one end of the embossing roller 5 with the clamping end of the three-jaw chuck 411, then translates the embossing roller 5, translates one end of the embossing roller 5 into the clamping end, and then starts the three-jaw chuck 411 to clamp one end of the embossing roller 5, and then starts the first cylinder 49, which drives the abutting member 410 to move, and finally the abutting member 410 abuts at the abutting hole position to clamp the other end of the embossing roller 5;

[0044] After the clamping is completed, the staff starts the laser engraving member 27, and the laser engraving member 27 is engraved according to the pre-edited program. After the engraving is completed, the staff first clamps the embossing roller member 5 with an auxiliary tool, then closes the three-jaw chuck 411 and the first cylinder 49, releases the clamping of the two ends of the embossing roller member 5, and then takes the embossing roller member 5 out of the device, and the engraving of the embossing roller member 5 is completed. The above is the existing technology of laser engraving of embossing rollers, which will not be described in detail here.

[0045] In order to realize the laser engraving operation on the embossing roller 5 without manual intervention and without interruption, as shown in FIG. Figure 1-Figure 3 As shown, a conveying device 3 is provided below the engraving device 2, and the conveying device 3 mainly provides the embossing roller 5 to be engraved for the laser engraving device 2, referring to Figure 3The conveying device 3 mainly includes a support leg 31, which is a supporting part of the conveying device 3 and is usually placed on a stable ground. A protective frame 32 is fixedly installed on the support leg 31. The protective frame 32 is an outer frame of the conveying device 3. At least two groups of driving rollers 33 are mounted on the inner side of the protective frame 32. A driving device (not shown in the figure) is connected to one side of the driving roller 33. The driving device can be a motor or a hydraulic motor, etc. When the driving device is started, it is suitable for driving the driving roller 33 to rotate;

[0046] Conveyor belts 34 are sleeved on both sides of the surface of the driving roller 33, and a lifting space (not shown in the figure) is formed between the middle section of the driving roller 33 and the conveyor belt 34. When the conveying device 3 is used to convey the embossing roller 5, both ends of the embossing roller 5 are placed on the conveyor belt 34, and the middle section is in the lifting space, so as to facilitate subsequent lifting and conveying;

[0047] Continue to refer Figure 3 A horizontal plate (not shown in the figure) is fixedly installed between the supporting legs 31. The horizontal plate mainly plays a supporting role. A lifting cylinder 6 for driving lifting and conveying is fixedly installed on the horizontal plate. The output end of the lifting cylinder 6 is away from the horizontal plate and is in the lifting space. A lifting piece 61 is fixedly installed on the output end of the lifting cylinder 6. The surface of the lifting piece 61 is an arc shape that matches the surface of the embossing roller 5. When the conveyor belt 34 conveys the embossing roller 5 to the position of the lifting piece 61, the staff can start the lifting cylinder 6 at this time. The lifting cylinder 6 starts to drive its output end to extend, and the lifting piece 61 rises and contacts the embossing roller 5. As the output end of the lifting cylinder 6 continues to extend, the lifting piece 61 drives the embossing roller 5 to rise synchronously and separate from the conveying equipment 3;

[0048] refer to Figure 1-Figure 2 In this embodiment, a transition chamber is provided on the base 1, and the transition chamber is located between the first clamping plate 44 and the second clamping plate 46. The transition chamber is mainly used to facilitate the conveying of the embossing roller 5 that is lifted and transported to between the first clamping plate 44 and the second clamping plate 46. The embossing roller 5 that is lifted and transported by the lifting member 61 is suitable for passing through the transition chamber to reach between the first clamping plate 44 and the second clamping plate 46, so as to facilitate the next step of installation of the embossing roller 5. Here, the position of the embossing roller 5 after lifting and transporting at this time can be understood as the position where the staff moves the embossing roller 5 after clamping it through the auxiliary equipment in the above text, and the subsequent installation of the embossing roller 5 is carried out;

[0049] When the embossing roller 5 is subsequently installed, the staff first starts the first cylinder 49, and the first cylinder 49 starts to drive the abutting member 410 to move. With the driving of the first cylinder 49, the abutting member 410 abuts against the abutting hole and continues to push the embossing roller 5. Since the embossing roller 5 is only placed on the lifting member 61 without being clamped at this time, under the push of the abutting member 410, one end of the embossing roller 5 moves toward the clamping end of the three-jaw chuck 411 and moves to the center position of the clamping end. It should be noted that after the lifting member 61 lifts the embossing roller 5 to the specified position, the embossing roller 5 still needs to be translated. Therefore, in order to reduce the friction between the surface of the embossing roller 5 and the surface of the lifting member 61, a layer of flexible pad can be added to the surface of the lifting member 61, and its material is similar to sponge, etc., so as to reduce the friction of the embossing roller 5 during the translation process.

[0050] When one end of the embossing roller 5 is pushed to the center position of the three-jaw chuck 411 through the first cylinder 49, the staff can start the three-jaw chuck 411 to clamp one end of the embossing roller 5, and the abutting member 410 is also abutted on the abutting hole, and the two ends of the embossing roller 5 are clamped by a clamping and a pushing method. Then the staff can control the laser engraving member 27 through the PLC system to start engraving the embossing roller 5. During the engraving process, the three-jaw chuck 411 can also be driven to rotate by the driving device to drive the clamped embossing roller 5 to rotate synchronously, so as to facilitate engraving at different positions thereof;

[0051] After the engraving is completed, the staff can control the lifting cylinder 6 to start again, and the lifting member 61 moves to between the first clamping plate 44 and the second clamping plate 46, and then control the three-jaw chuck 411 to relax, so that one end of the embossing roller member 5 is suitable for detaching from the gap between the multiple groups of clamping jaws in the clamping end. At this time, the staff needs to control the first cylinder 49 to close, and the output end of the first cylinder 49 retracts to drive the holding member 410 to retract synchronously. After losing the clamping and holding force, the processed embossing roller member 5 falls on the lifting member 61, and then the lifting cylinder 6 is controlled to close again, and the output end of the lifting cylinder 6 retracts to drive the lifting member 61 to move down, and drive the embossing roller member 5 to move down back to the conveyor belt 34, and continue to be transported forward via the conveyor belt 34, and the subsequent embossing roller members 5 will move to the position of the lifting member 61 one after another, and then the lifting cylinder 6 is turned on again to start the next round of laser engraving operation;

[0052] In this process, the embossing roller 5 can be installed without the assistance of personnel to clamp and transport the embossing roller 5, and multiple groups of embossing rollers 5 can be prepared in advance through the conveying mechanism, and each group of electrical components can be turned on and used alternately through the PLC control system, without the need for personnel to intervene in the installation. However, when clamping or disassembling the embossing roller 5, only one group of three-jaw chucks 411 and one group of first cylinders 49 and abutting members 410 are used. In this way, during the disassembly and assembly process, the laser engraving member 27 will still be idle for a long time. In order to solve this problem, Figure 1-Figure 2 As shown, the number of three-jaw chucks 411 is two groups, and the number of first cylinders 49 and abutting members 410 corresponds to the number and position of the three-jaw chucks 411, as shown in FIG. Figure 1 or Figure 2 It is known that one set of three-jaw chucks 411 is in a high position, and the other set of three-jaw chucks 411 is in a low position. For the convenience of description, the three-jaw chucks 411 in the high position are defined as the working position, and the three-jaw chucks 411 in the low position are defined as the preparation position. However, the working position and the preparation position are suitable for driving the first clamping disk 44 to rotate by the driving motor 43 to exchange positions.

[0053] Since the second clamping plate 46, the abutting member 410 and the first cylinder 49 are fixedly installed, when the position of the three-jaw chuck 411 is changed, the positions of the corresponding abutting member 410 and the first cylinder 49 cannot be changed. If the embossing roller 5 with only one end clamped is rotated at this time, the clamping may be unstable and the embossing roller 5 may fall off. In order to solve this problem, Figure 1-Figure 2 As shown, a connecting shaft 47 is fixedly installed at the center of the first clamping disk 44, and the other end of the connecting shaft 47 is connected to the second clamping disk 46 through a bearing. An auxiliary clamping disk 48 is slidably installed on the connecting shaft 47. When subjected to external force, the auxiliary clamping disk 48 is suitable for sliding on the connecting shaft 47. It should be noted that a protrusion is provided on the connecting shaft 47, and a groove is provided at the position where the auxiliary clamping disk 48 and the connecting shaft 47 are connected. The protrusion is adapted to the groove, and then when the first clamping disk 44 is driven to rotate by the driving motor 43, the auxiliary clamping disk 48 rotates synchronously. Secondly, when processing embossing rollers 5 of different lengths, the staff can manually push the auxiliary clamping disk 48 to slide to adjust the position of the auxiliary component 481, so that the auxiliary component 481 can always be located in the middle section of the embossing roller 5, further enhancing the stability of the embossing roller 5 after clamping;

[0054] like Figure 5 , Figure 7-Figure 8As shown, both ends of the auxiliary clamping disk 48 are equipped with auxiliary parts 481 through fixing parts. The auxiliary part 481 is an electromagnet with an arc surface, and a magnetic surface 482 is arranged on the side away from the auxiliary clamping disk 48. The magnetic surface 482 is arranged in an arc shape to match the surface of the embossing roller 5, and the position of the auxiliary part 481 corresponds to the position of the three-jaw chuck 411. The PLC system is suitable for controlling the auxiliary part 481 to be energized to adsorb the embossing roller 5, and the magnetic surface 482 contacts the surface of the embossing roller 5. At the same time, the auxiliary clamping disk 48 can move freely, and the auxiliary part 481 can always adsorb the middle section of the embossing roller 5, so that the clamping of the embossing roller 5 is more stable.

[0055] When performing laser engraving operations, the working position and the preparation position are in their corresponding positions, and then the lifting member 61 lifts the embossing roller 5 to the preparation position, and the PLC control system controls the first cylinder 49 and the three-jaw chuck 411 to start successively to clamp the embossing roller 5. The specific clamping method can refer to the operation process of the three-jaw chuck 411 and the first cylinder 49 mentioned above. After the embossing roller 5 is clamped, the surface of the embossing roller 5 is in contact with the magnetic surface 482, and the PLC control system controls the auxiliary member 481 to be energized. Due to the magnetic effect, the auxiliary member 481 absorbs the embossing roller 5 and plays a certain auxiliary clamping role. The difference from the above working process is that when the auxiliary member 48 After the embossing roller 5 is adsorbed, the first cylinder 49 is closed, and the abutting member 410 is separated from the embossing roller 5. Then, the PLC control system controls the driving motor 43 to start, and the driving motor 43 starts to drive the first clamping plate 44 to rotate, and the first clamping plate 44 drives the preparatory position and the working position to exchange positions. At this time, the working position is at the original position of the preparatory position, and the preparatory position rotates to the high position at the original working position. Then, the PLC control system can control the first cylinder 49 at the high position to start, and the first cylinder 49 starts to drive the abutting member 410 to move, and clamp the embossing roller 5 at the high position. In this process, the auxiliary clamping plate 48 will also rotate, and the auxiliary member 481 will rotate synchronously, such as Figure 5 As shown in , when the embossing roller 5 is in a high position, the auxiliary member 481 is located below the embossing roller 5, playing a certain supporting role. At this time, the embossing roller 5 is clamped by the three-jaw chuck 411, the auxiliary member 481 and the abutting member 410, and the clamping is more stable. Then the PLC control system can control the start of the laser engraving member 27 to start engraving;

[0056] While engraving, the lifting member 61 continues to lift and transport the embossing roller 5, and the working position can clamp another group of embossing rollers 5 for preparatory processing. After the embossing rollers 5 at the preparatory position are processed, the PLC control system controls the driving motor 43 to drive the first clamping disk 44 to rotate, and the preparatory position and the working position are exchanged. The working position returns to the high position, and the laser engraving operation of another group of embossing rollers 5 can be started. At this time, the preparatory position returns to the low position, and the PLC control system controls the three-jaw chuck 411 and the first cylinder 49 to alternately open and cooperate with the disassembly of the embossing rollers 5 after the processing is completed. After the disassembly is completed, the lifting member 61 lifts and transports another group of embossing rollers 5, and installs another group of embossing rollers 5. In this way, during the disassembly and assembly process of the embossing rollers 5, there is always a group of embossing rollers 5 being processed, which improves the efficiency of laser engraving of the embossing rollers 5.

[0057] In this embodiment, the auxiliary component 481 is connected to the auxiliary clamping plate 48 via a fixing component, so that the auxiliary component 481 can be disassembled manually and auxiliary components 481 of different sizes can be replaced to adapt to embossing roller components 5 of different sizes.

[0058] Embodiment 2: The above embodiment realizes uninterrupted laser engraving without manual intervention by providing a conveying device 3, a lifting cylinder 6, and two sets of three-jaw chucks 411, etc. However, when the conveying device 3 is conveying multiple sets of embossing rollers 5, some of the embossing rollers 5 may be in an inclined state when on the conveyor belt 34. After being lifted and conveyed by the lifting member 61, they will be clamped in an inclined state. The embossing rollers 5 clamped in an inclined state are engraved, which will undoubtedly affect the quality of laser engraving.

[0059] In order to solve this problem, this embodiment adds a calibration device 7 on the basis of the above embodiment, and performs secondary positioning and clamping on the embossing roller 5 by secondary clamping and calibration to ensure that it will not tilt and affect the subsequent processing quality;

[0060] like Figure 4-Figure 6 As shown, a calibration device 7 is fixedly mounted on the second clamping plate 46, and the calibration device 7 includes a second cylinder 71 fixedly mounted on the second clamping plate 46, and the second cylinder 71 is located above the first cylinder 49 at a high position, corresponding to the working position. It can be understood that the calibration device 7 is mainly used to calibrate the embossing roller 5 to be laser engraved;

[0061] A connecting member 72 is fixedly installed on the output end of the second cylinder 71. The connecting member 72 mainly consists of a cross bar fixedly installed on the output end of the second cylinder 71 and a vertical plate fixedly connected to the cross bar. The vertical plate and the cross bar are vertically arranged. A calibration sleeve 73 is fixedly installed at the bottom of the vertical plate. It should be noted that the interior of the calibration sleeve 73 is hollow and has openings at both ends. The diameter of the inner surface of the calibration sleeve 73 is slightly larger than the diameter of the embossing roller 5. A bell mouth is provided at the end of the calibration sleeve 73 away from the second cylinder 71. The diameter of the bell mouth increases continuously in the direction away from the second cylinder 71. The main purpose is to guide the inclined embossing roller 5 so that the surface of the embossing roller 5 can contact the inner surface of the calibration sleeve 73 through the bell mouth.

[0062] However, in order to achieve the purpose of calibration, the accuracy and stability of the calibration sleeve 73 are often not enough only by controlling the calibration sleeve 73 to move forward and backward by the cylinder. Figure 6 At least two groups of calibration slide bars 74 are fixedly mounted on the second clamping plate 46, and the groups of calibration slide bars 74 are on the same horizontal plane. A sliding sleeve 75 is slidably mounted on the calibration slide bars 74, and the sliding sleeve 75 is fixedly connected to the calibration sleeve 73. When the calibration sleeve 73 moves, the sliding sleeve 75 slides on the calibration slide bars 74. In order to prevent the sliding sleeve 75 from being separated from the calibration slide bars 74, a sphere is fixedly mounted on one end of the calibration slide bars 74 away from the second clamping plate 46, and the diameter of the sphere is larger than the diameter of the sliding sleeve 75.

[0063] It should be noted that, in the initial state, the calibration sleeve 73 is located near the second clamping disk 46, and the position of its bell mouth to the second clamping disk 46 is closer than the position of the abutting member 410 to the second clamping disk 46, mainly for the purpose of not blocking the embossing roller 5 from rotating from a low position to a high position. During calibration, the calibration sleeve 73 gradually moves away from the second clamping disk 46, and a part of the main body of the embossing roller 5 is sleeved in the sleeve, and the inclined embossing roller 5 is adjusted to be on the same axis as the calibration sleeve 73, thereby realizing the calibration of the embossing roller 5;

[0064] During laser engraving, after the embossing roller 5 adsorbed by the three-jaw chuck 411 and the auxiliary component 481 rotates to a high position, the PLC control system then controls the second cylinder 71 to start, and the output end of the second cylinder 71 drives the connecting component 72 to move in a direction away from the second clamping plate 46, and the connecting component 72 drives the calibration sleeve 73 to move, and the sliding sleeve 75 slides on the surface of the calibration slide bar 74. As the calibration sleeve 73 continues to move, its bell mouth will contact the outer surface of the main body of the embossing roller 5, and then the inner wall of the calibration sleeve 73 will contact the outer surface of the embossing roller 5, and the inclined embossing roller 5 will be calibrated to be on the same axis as the calibration sleeve 73;

[0065] It should be noted that, since the three-jaw chuck 411 clamps one end of the embossing roller 5 during the calibration process, the state of the embossing roller 5 cannot be adjusted at this time, and then when the bell mouth contacts the embossing roller 5, the PLC system controls the three-jaw chuck 411 to relax, but it is not in a completely relaxed state, and the gap between each single jaw is small, and one end of the embossing roller 5 cannot escape from the gap between the single jaws. At the same time, the auxiliary component 481 is in an adsorption state for the embossing roller 5 and plays a certain supporting role, and as the calibration sleeve 73 moves, the calibration sleeve 73 covers part of the main body of the embossing roller 5, which also plays a limiting role, and the embossing roller 5 will fall from a high position and can be calibrated;

[0066] After the calibration is completed, that is, after the second cylinder 71 is extended to the limit position, the PLC control system controls the three-jaw chuck 411 to clamp one end of the embossing roller 5 again, and at the same time starts the first cylinder 49, the abutting member 410 abuts on the abutting hole, and the secondary clamping of the embossing roller 5 is completed. Then the PLC control system controls the second cylinder 71 to close, and the calibration sleeve 73 returns to the initial position. Finally, the PLC control system controls the laser engraving member 27 to start the engraving operation;

[0067] In the above process, the calibration device 7 is provided to realize secondary positioning and clamping of the embossing roller 5, so as to ensure that the embossing roller 5 maintains a horizontal straight line during the processing, thereby improving the quality of laser engraving to a certain extent.

[0068] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
