Description

Technical Field

[0001] This utility model relates to the field of printing accessories manufacturing, specifically to the laser engraving ceramic anilox roller industry, and particularly to a dust collection device for engraving ceramic anilox rollers. Background Technology

[0002] Ceramic anilox rollers are precision rollers with a ceramic coating. Their core feature is the formation of a uniform, micron-sized network of cells (typically honeycomb or oblique grooves) on the ceramic surface through laser engraving. They are primarily used in the printing, coating, composite material molding, and functional surface treatment industries. In the printing industry, as a core component of flexographic and gravure printing, they store ink through the cells and precisely transfer it to the substrate (such as plastic film or paper), controlling ink layer thickness and printing uniformity.

[0003] The manufacturing process of ceramic anilox rollers generally includes the following steps in sequence: ① substrate pretreatment ② plasma spraying of ceramic layer ③ surface grinding ④ laser engraving of cells ⑤ post-processing. In the laser engraving process, the current dust collection device is located around the laser engraving port. However, this exposed environment is ineffective for rollers with low line counts, spiral patterns, and large mesh sizes. The engraved dust cannot be completely removed, resulting in a large amount of ceramic powder on the roller surface that is difficult to clean. A significant portion of the ceramic powder remains in the workshop, potentially impacting the health of the operators.

[0004] Therefore, there is a need for a dust collection device that enhances dust collection, prevents ceramic dust from remaining on the roller surface or in the workshop after engraving, reduces cleaning difficulty, and minimizes the impact on the health of operators. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a technical solution for a dust collection device that enhances dust collection effect, prevents ceramic dust from remaining on the roller surface or workshop after engraving, reduces cleaning difficulty, and reduces the impact on the health of operators.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A dust collection device for ceramic anilox roller engraving, suitable for a laser engraving head that irradiates a ceramic roller body with a laser for engraving operations.

[0008] A dust collection hood is provided between the laser engraving head and the ceramic roller. The dust collection hood is a hollow cylindrical body. One end of the dust collection hood is fixedly connected to the housing of the laser engraving head, and the other end of the dust collection hood is close to the ceramic roller. The inner cavity of the dust collection hood communicates with the inner cavity of the laser engraving head housing.

[0009] The dust collection hood is provided with a first air inlet channel on its upper side, and the air outlet of the first air inlet channel extends into the dust collection hood, with the air outlet of the first air inlet channel facing the ceramic roller.

[0010] The dust collection hood has a dust collection port on its lower side wall, and a dust collection container communicating with the dust collection port is provided on the lower side of the dust collection hood. The dust collection container is also equipped with a dust suction pump.

[0011] By adopting the above technical solution, a relatively enclosed area is formed by the dust collection hood extending from the laser engraving head to the ceramic roller, allowing the focusing lens to perform laser engraving on the surface of the ceramic roller. Then, air is blown onto the ceramic roller through the first air inlet channel, blowing away the dust generated during laser engraving from the surface of the ceramic roller, which is then sucked away by the dust collection port for centralized storage or disposal. In this way, dust will not easily escape from the dust collection port due to being in an open space. Because a relatively enclosed area is created, even if dust moves outward, it can be blocked by the negative pressure effect generated by the working dust suction pump, making it difficult for it to enter the workshop and harm the health of the operators.

[0012] As an improvement, the system also includes windproof bristles, the roots of which are located at the other end of the dust collection hood, referred to here as the free end of the dust collection hood for ease of understanding. Correspondingly, the other end of the dust collection hood is defined here as the connecting end. The tips of the windproof bristles abut against the ceramic roller; the windproof bristles are continuously arranged along the free end of the dust collection hood, forming a closed loop.

[0013] By adopting the above technical solution, the gap between the dust collection cover and the ceramic roller is filled with windproof brush bristles to prevent the smoke and dust from laser engraving from overflowing from the gap. Moreover, since the windproof brush bristles are made of soft material, they are less likely to cause bumps or knocks to the ceramic roller during the laser engraving process.

[0014] As an improvement, a dust removal roller is provided on the free end of the dust collection hood, and the dust removal roller is provided with dust removal bristles, and the dust removal roller rotates inward.

[0015] By adopting the above technical solution, the dust removal brush bristles sweep the dust on the outer surface of the ceramic roller from the outside to the inside during the rotation of the dust removal roller, which has a good cleaning effect on the dust inside the engraved lines of the ceramic roller and prevents the dust from being carried into the workshop.

[0016] As an improvement, an external air pressure sensor is provided on the outer surface of the dust collection hood, and an internal air pressure sensor is provided on the inner surface of the dust collection hood; a display screen is provided on the outer surface of the dust collection hood, and the display screen is connected to the signals of the external air pressure sensor and the internal air pressure sensor respectively.

[0017] By adopting the above technical solution, real-time air pressure data of the outside and inside of the dust collection hood can be displayed on the screen, and the operation of the vacuuming device can be checked by reading the internal air pressure data.

[0018] As an improvement, the dust collection hood is divided into a first compartment and a second compartment by a partition wall. The first compartment is close to the ceramic roller and has a first air inlet and a dust collection port. The second compartment is close to the laser engraving head. The partition wall has a connecting channel that connects the first compartment and the second compartment. The laser engraving head irradiates a laser and focuses the laser on the engraving position on the surface of the ceramic roller. The position of the connecting channel matches the path of the laser irradiation. The second compartment has a second air inlet.

[0019] By adopting the above technical solution, the laser engraving head is located in the second chamber, and the gas blown out from the second air intake channel enters the first chamber from the second chamber through the connecting channel. This allows the connecting channel to maintain airflow to the first chamber without hindering the laser engraving operation. On the one hand, it can generate airflow from the laser engraving head to the laser engraving position, enhancing the effect of blowing away dust generated during laser engraving. On the other hand, it can also prevent dust from entering the second chamber from the first chamber, thus preventing dust from contaminating the laser engraving head and affecting the laser engraving effect.

[0020] As an improvement, the cross-sectional area of ​​the connecting channel gradually decreases along the direction from the laser engraving head to the ceramic roller.

[0021] By adopting the above technical solution, the connecting channel gradually narrows along the direction of the laser engraving head towards the ceramic roller, and the airflow also gradually accelerates, preventing dust from entering the second chamber and preventing dust from contaminating the focusing lens.

[0022] As an improvement, a third air intake channel is provided in the first compartment, and the third air intake channel is oriented towards the partition wall. Preferably, the third air intake channel is located on the dust collection hood and close to the partition wall; more preferably, the airflow direction of the third air intake channel is parallel to the surface of the partition wall in the first compartment.

[0023] By adopting the above technical solution, the airflow blown out by the third air intake channel is directed toward the partition wall, preventing dust from accumulating on the partition wall of the first compartment, reducing the number of times the external work area needs to be cleaned and maintaining, and improving maintainability.

[0024] As an improvement, the first compartment is equipped with a wind deflector, which is installed on the partition wall and surrounds the connecting channel.

[0025] By adopting the above technical solution, the airflow blown out of the connecting channel can be protected from being distorted by the airflow blown out of the third air intake channel, and the airflow in the connecting channel can be prevented from deviating and failing to reach the laser engraving position.

[0026] As an improvement, an adjustable sleeve is fitted on the outer surface of the second compartment; the adjustable sleeve is connected to the laser engraving head; the second compartment is slidably disposed on the inner wall of the adjustable sleeve, and the adjustable sleeve is also provided with a locking mechanism for fixing the relative position of the second compartment and the adjustable sleeve.

[0027] By adopting the above technical solution, the second chamber can be extended or shortened within the range allowed by the adjusting sleeve, thereby adapting to laser engraving heads with different focal lengths.

[0028] As an improvement, the locking mechanism includes a threaded hole penetrating the side wall of the adjusting sleeve, and a locking screw threadedly connected to the threaded hole.

[0029] By adopting the above technical solution, as long as the locking screw rotates and applies pressure to the outer wall of the second compartment to generate friction, the relative positional relationship between the second compartment and the adjusting sleeve can be fixed, and there is no minimum adjustment distance limit for adjusting the relative position between the second compartment and the adjusting sleeve.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] A dust collection hood extending from the laser engraving head to the ceramic roller creates a relatively enclosed area for the focusing lens to perform laser engraving on the surface of the ceramic roller. Air is then blown through the first air inlet channel towards the engraving location, blowing away the dust generated during laser engraving from the surface of the ceramic roller, which is then sucked away by the dust collection port for centralized storage or disposal. This prevents dust from easily escaping from the dust collection port due to the open space. Because of the relatively enclosed area, even if dust moves outward, the negative pressure generated by the suction pump prevents it from entering the workshop and harming the health of the operators.

[0045] Implementation Case 1:

[0046] As attached Figure 1 and 3 As shown, a dust collection device for ceramic anilox roller engraving is provided, which is suitable for a laser engraving head 4 that irradiates a laser onto a ceramic roller body 5 for engraving operations. The irradiating laser is focused on the engraving position 6 on the surface of the ceramic roller body 5.

[0047] The system includes a dust collection hood 2 mounted on the laser engraving head 4. The dust collection hood 2 includes a connecting end 202 connected to the laser engraving head 4 and a free end 203 facing the ceramic roller body 5. The free end 203 is positioned close to the ceramic roller body 5 and is a continuous closed ring shape that matches the side shape of the ceramic roller body 5.

[0048] The dust collection hood 2 is a hollow cylindrical shape and is arranged around the engraving laser and the engraving position 6;

[0049] The dust collection hood 2 is provided with a first air intake channel 1 on its upper side. The first air intake channel 1 extends into the dust collection hood 2, and the air intake of the first air intake channel 1 is set towards the engraving position 6.

[0050] The dust collection hood 2 has a dust collection port 3 on its lower side. The dust collection port 3 is connected to a dust collection container 24 installed outside the dust collection hood 2. A dust suction pump 7 is also installed on the dust collection container 24.

[0051] A dust collection hood 2, extending from the laser engraving head 4 to the ceramic roller 5, encloses a relatively enclosed area for the focusing lens to perform laser engraving on the surface of the ceramic roller 5. Air is then blown through the first air inlet channel 1 towards the engraving position 6, blowing away the dust generated during laser engraving from the surface of the ceramic roller 5, which is then sucked away by the dust collection port 3 for centralized storage or disposal. This prevents dust from easily escaping from the dust collection port 3 due to its open space. Because of the relatively enclosed area, even if dust moves outward, it is blocked by the negative pressure generated by the suction pump 7, making it difficult for it to enter the workshop and harm the health of the operators.

[0052] It also includes windproof bristles 8, the roots of which are disposed on the free end 203 of the dust collection hood 2, and the tips of which are disposed against the ceramic roller body 5; the windproof bristles 8 are continuously disposed along the free end 203 of the dust collection hood 2 and form a closed loop.

[0053] The bristles 8 are used to fill the gap between the dust collection cover 2 and the ceramic roller 5 to prevent the smoke and dust from laser engraving from overflowing from the gap. Moreover, since the bristles 8 are made of soft material, they are less likely to cause bumps or knocks to the ceramic roller 5 during the laser engraving process.

[0054] The dust collection hood 2 is divided into a first chamber 14 and a second chamber 15 by a partition wall 16. The first chamber 14 is close to the ceramic roller 5 and is provided with a first air inlet 1 and a dust collection port 3. The second chamber 15 is close to the laser engraving head 4. The partition wall 16 is provided with a connecting channel 18 that connects the first chamber 14 and the second chamber 15. The position of the connecting channel 18 matches the position of the engraving laser. The second chamber 15 is provided with a second air inlet 17.

[0055] The laser engraving head 4 is located in the second chamber 15. The gas blown out by the second air intake channel 17 enters the first chamber 14 from the second chamber 15 via the connecting channel 18. The connecting channel 18 can be maintained to blow air into the first chamber 14 without hindering the laser engraving operation. On the one hand, it can generate airflow from the laser engraving head 4 to the laser engraving position 6, which can enhance the effect of blowing away the dust generated by laser engraving. On the other hand, it can also prevent dust from entering the second chamber 15 from the first chamber 14, thus preventing dust from contaminating the laser engraving head 4 and affecting the laser engraving effect.

[0056] The cross-sectional area of ​​the connecting channel 18 gradually decreases along the direction from the laser engraving head 4 to the ceramic roller 5.

[0057] As the connecting channel 18 gradually narrows along the direction from the laser engraving head 4 to the ceramic roller 5, the airflow will also gradually accelerate, preventing dust from entering the second chamber 15 and preventing dust from contaminating the focusing lens.

[0058] The first compartment 14 is provided with a third air intake channel 19, which is disposed toward the partition wall 16. Preferably, the third air intake channel 19 is disposed on the dust collection hood 2 and close to the partition wall 16; more preferably, the airflow direction of the third air intake channel 19 is parallel to the surface of the partition wall 16 in the first compartment 14.

[0059] The airflow from the third air intake duct 19 blows towards the partition wall 16, preventing dust from accumulating on the partition wall 16 of the first compartment 14, reducing the frequency of maintenance and cleaning of the outer working area, and improving maintainability.

[0060] The first compartment 14 is provided with a wind deflector 20, which is disposed on the partition wall 16 and surrounds the connecting channel 18.

[0061] It can protect the airflow blown out of the connecting channel 18 from being distorted by the airflow blown out of the third air intake channel 19, and prevent the airflow of the connecting channel 18 from deviating and failing to reach the laser engraving position 6.

[0062] Implementation Case 2:

[0063] As attached Figure 2 As shown, a dust collection device for ceramic anilox roller engraving has the same overall structure as Implementation Case 1, but its improvement over Implementation Case 1 lies in:

[0064] 1) A dust removal roller 9 is provided on the free end 203 of the dust collection hood 2, and a dust removal brush bristle 10 is provided on the dust removal roller 9. The dust removal roller 9 rotates inward.

[0065] As the dust removal roller 9 rotates, the dust removal brush 10 sweeps the dust on the outer surface of the ceramic roller 5 from the outside to the inside, which has a good cleaning effect on the dust inside the engraved lines of the ceramic roller 5 and prevents the dust from being carried into the workshop.

[0066] 2) An external air pressure sensor 11 is provided on the outer surface of the dust collection hood 2, and an internal air pressure sensor 12 is provided on the inner surface of the dust collection hood 2; a display screen 13 is provided on the outer surface of the dust collection hood 2, and the display screen 13 is connected to the external air pressure sensor 11 and the internal air pressure sensor 12 respectively.

[0067] It can display real-time air pressure data of the outside and inside of the dust collection hood 2 on the display screen 13, and can check whether the vacuuming device is operating normally by reading the internal air pressure data.

[0068] 3) An adjusting sleeve 22 is fitted on the outer surface of the second compartment 15; the adjusting sleeve 22 is connected to the laser engraving head 4; the second compartment 15 is slidably disposed on the inner wall of the adjusting sleeve 22, and the adjusting sleeve 22 is also provided with a locking mechanism for fixing the relative position of the second compartment 15 and the adjusting sleeve 22.

[0069] This allows the second chamber 15 to extend or shorten within the range permitted by the adjusting sleeve 22, thereby enabling it to be used with laser engraving heads 4 of different focal lengths.

[0070] The locking mechanism includes a threaded hole penetrating the side wall of the adjusting sleeve 22, and a locking screw 23 threadedly connected to the threaded hole.

[0071] As long as the locking screw 23 rotates and applies pressure to the outer wall of the second compartment 15 to generate friction, the relative positional relationship between the second compartment 15 and the adjusting sleeve 22 can be fixed, and there is no minimum adjustment distance limit for the relative position adjustment between the second compartment 15 and the adjusting sleeve 22.

[0072] In summary, after reading this utility model document, those skilled in the art can make various other corresponding modifications based on the technical solution and concept of this utility model without creative mental effort. Different application scenarios are all within the scope of protection of this utility model.
