Description

Technical Field

[0001] The invention relates to the technical field of laser engraving, and in particular to a copper-plated steel roller surface embossing laser engraving device and an embossing plate roller manufacturing method. Background Art

[0002] Embossing rollers play an important role in many industrial productions. For example, they can emboss specific texture patterns on the surface of paper, leather, plastic film and other materials to increase the beauty and added value of the products. As an advanced processing method, laser engraving technology has the advantages of high flexibility and non-contact processing, but the existing laser engraving machines still have some problems when processing special cylindrical surfaces such as embossing rollers.

[0003] The surface of the embossing roller is not fully cleaned, and there are impurities such as rust and oxide scale on its surface. During the laser engraving process, these impurities will melt or burn under high temperature to form substances similar to welding slag. If these welding slags are not handled in time, they will adhere to the surface of the embossing roller and make it rough and uneven. The rough surface will cause the embossed pattern to be unclear and inconsistent in depth. At the same time, it will destroy the expected structure of the embossing roller and reduce the performance of the embossing roller.

[0004] Currently, an auxiliary gas system is usually used to blow the molten metal or impurities away from the engraving area through auxiliary gas (such as argon, nitrogen, etc.), but the following problems still exist. Since the welding slag is usually located in the engraving area of ​​the embossing roller, the ordinary airflow cannot effectively blow out all the welding slag inside the engraving area due to insufficient blowing force and scattered points of action of the wind force. The residual welding slag will also affect the engraving accuracy and production quality. Therefore, it is necessary to design a laser engraving device that can directly act on the welding slag in the engraving groove in a spiral flow manner with auxiliary gas, so as to effectively ensure the engraving accuracy and production quality.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] Example 1, reference Figure 1-Figure 8 , which is the first embodiment of the present invention, provides a copper-plated steel roller surface embossing laser engraving device, comprising a base plate 1, a plurality of fixing frames 2 fixedly mounted on the side wall of the base plate 1, a support plate 3 fixedly mounted on two corresponding fixing frames 2, and an engraving unit mounted on the support plate 3, wherein the engraving unit comprises a cleaning component and an engraving component mounted between the two support plates 3.

[0048] The cleaning components include two sliding rods 4 fixedly installed between the two support plates 3, a sliding load-bearing ring 5 slidably installed between the two sliding rods 4, a ventilation ring groove 6 opened inside the sliding load-bearing ring 5, an upper seat plate 7 fixedly installed on the upper end of the sliding load-bearing ring 5, a small powerful fan 8 fixedly installed on the upper end of the upper seat plate 7, a connecting pipe 9 fixedly installed between the small powerful fan 8 and the upper seat plate 7, a rotating air outlet ring 10 rotatably installed inside the ventilation ring groove 6, an air outlet pipe 11 equidistantly fixedly installed on the outer wall of the rotating air outlet ring 10 with the center of the rotating air outlet ring 10 as the axis point, and multiple blowing holes 12 opened on the side walls of the air outlet pipe 11.

[0049] A nitrogen box is fixedly installed on the base plate 1, and the nitrogen box is fixedly connected to the air inlet of the small powerful fan 8, and the air outlet of the small powerful fan 8 is connected to the connecting pipe 9. The lower end of the connecting pipe 9 is connected to the ventilation ring groove 6, and multiple outlet pipes 11 are all connected to the ventilation ring groove 6. The rotating air outlet ring 10 is rotatably installed on the inner wall of the ventilation ring groove 6, and the side wall of the air outlet pipe 11 is set to a 45° inclined surface. The blowing hole 12 is opened on the inclined surface corresponding to the air outlet pipe 11, and a rotating assembly is arranged at the lower end of the rotating air outlet ring 10. A collecting assembly is installed on one side of the sliding load-bearing ring 5, and a clamping assembly is installed between the two support plates 3.

[0050] Reference Figure 4-Figure 8 The rotating assembly includes a lower seat plate 13 fixedly mounted on the lower end of the sliding load-bearing ring 5, a driving motor 14 fixedly mounted on the lower seat plate 13, a driving shaft 15 fixedly mounted on the driving end of the driving motor 14, a driving gear 16 fixedly mounted on one end of the driving shaft 15, and a driven gear ring 17 fixedly mounted on the side wall of the rotating air outlet ring 10, wherein the upper end of the driving gear 16 meshes with the lower end of the driven gear ring 17. The collecting assembly includes a round rod 18 fixedly mounted between the two supporting plates 3, a synchronous plate 19 fixedly mounted on one side of the sliding load-bearing ring 5, the synchronous plate 19 slidably mounted on the round rod 18, an exhaust fan 20 fixedly mounted on the upper end of the synchronous plate 19, a collecting box 21 fixedly mounted at the air outlet of the exhaust fan 20, and a filter plate 22 fixedly mounted on the inner wall of the collecting box 21.

[0051] Specifically, the working principle of the cleaning component is: by generating a spiral flow of auxiliary gas and directly acting on the engraving area at a certain angle, while cooling the engraving area, the spiral flow of auxiliary gas blows the welding slag in the engraving area out of the engraving groove. Compared with the existing direct current method of cleaning welding slag, the spiral flow of auxiliary gas can better blow up the welding slag, and blowing at a certain angle can better blow out the welding slag, effectively improving the production quality and engraving accuracy. The blowing holes 12 on the rotating air outlet ring 10 alternately blow up the welding slag, while the remaining blowing holes 12 can cool the engraving area after cleaning, which can make the engraving area shape faster, thereby improving the engraving efficiency and quality.

[0052] By setting a collection component, the exhaust fan 20 in the collection component collects the blown welding slag in the collection box 21, collects the blown welding slag, prevents the cleaning component from blowing the welding slag and dropping it everywhere, causing the surrounding environment to be affected, and can effectively prevent part of the welding slag from falling back into the engraving groove under the action of gravity, which again affects the engraving accuracy and welding quality. At the same time, by setting a filter plate 22 to filter the welding slag, it is prevented from being blown into the exhaust fan 20 under the action of the exhaust fan 20, causing damage to the exhaust fan 20. At the same time, the filter plate 22 can effectively block the welding slag in the collection box 21, which is convenient for subsequent cleaning work by staff.

[0053] During use, the staff turns on the small powerful fan 8 and the exhaust fan 20, and turns on the drive motor 14. The drive motor 14 drives the drive gear 16 to rotate through the drive shaft 15, and then drives the upper driven gear ring 17 to rotate through the drive gear 16. The driven gear ring 17 rotates and drives the rotating outlet ring 10 to rotate in the ventilation ring groove 6. At the same time, the airflow generated by the small powerful fan 8 directly enters the ventilation ring groove 6 through the connecting pipe 9. The nitrogen flow entering the ventilation ring groove 6 passes through the outlet pipe 11. The air holes 12 blow out, and because the rotating air outlet ring 10 rotates continuously, the air outlet pipe 11 rotates synchronously, and the multiple air outlet pipes 11 alternately act on the nitrogen flow into the engraving groove while rotating. At the same time, the air holes 12 act on the engraving groove at a certain angle, so the nitrogen blown out from the air holes 12 acts on the welding slag in the engraving groove in a spiral flow manner, so that the welding slag is blown up by the airflow, and at the same time, the exhaust fan 20 sucks the welding slag blown in the air into the collection box 21 for collection, thereby completing the cleaning and collection of the welding slag.

[0054] Example 2, reference Figure 1-Figure 2 as well as Figure 9-12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the engraving component includes a guide rod 23 fixedly installed between the two support plates 3, a slide groove 24 provided at the upper and lower ends of the guide rod 23, a plurality of pulleys 25 slidably installed inside the slide grooves 24 at the upper and lower ends, shafts 26 rotatably installed at the axis centers of the plurality of pulleys 25, two driving plates 27 fixedly installed at the two ends of the plurality of shafts 26, a laser 28 fixedly installed on the side walls of the driving plates 27, a synchronization component installed between the two driving plates 27 and the small powerful fan 8 and the collection box 21, and a driving component installed at one end of the two driving plates 27.

[0055] Specifically, the driving plate 27 is slidably installed in the slide groove 24 on the guide rod 23 through the pulley 25. The position of the laser 28 on the driving plate 27 is controlled by controlling the sliding position of the driving plate 27 on the guide rod 23. The pulleys 25 installed at the upper and lower ends can limit the driving plate 27 in the vertical direction, so that the driving plate 27 can automatically slide in the horizontal direction while preventing the driving plate 27 from driving the laser 28 to shake in the vertical direction, thereby effectively improving the stability of the laser 28.

[0056] Reference Fig.11 and Fig.12 The synchronization assembly includes a connecting plate 29 fixedly mounted on the side wall of the driving plate 27, a connecting rod 30 fixedly mounted between the connecting plate 29 and the small powerful fan 8, a connecting plate 31 fixedly mounted on the side wall of the driving plate 27 at one end away from the laser 28, and a connecting rod 32 fixedly mounted between the connecting plate 31 and the collecting box 21. The driving assembly includes a push plate 33 fixedly mounted between the two driving plates 27, a bracket 34 fixedly mounted on the side wall of the support plate 3, and a cylinder 35 fixedly mounted on the upper end of the bracket 34, and the telescopic end of the cylinder 35 is fixedly connected to the push plate 33.

[0057] Specifically, since the air blowing hole 12 on the rotating air outlet ring 10 must always face the engraving area, when the laser 28 is engraving, the rotating air outlet ring 10 and the collection box 21 must always move with the movement of the laser 28. Therefore, by setting a synchronization component, when the telescopic end of the cylinder 35 controls the laser 28 to move in the horizontal direction, the connecting plate 1 29 and the connecting plate 2 31 can drive the corresponding rotating air outlet ring 10 and the collection box 21 to move synchronously, so that the air blowing hole 12 on the rotating air outlet ring 10 is always facing the area when the laser 28 is engraving, which can effectively ensure the cleaning efficiency of the rotating air outlet ring 10 in the engraving groove and the efficiency of the collection box 21 in collecting the blown welding slag.

[0058] During use, when the laser 28 needs to move in the horizontal direction to adjust its position during the engraving process, the push plate 33 is driven to move in the horizontal direction through the telescopic end of the cylinder 35, and the push plate 33 drives the laser 28 on its upper end to move synchronously through the driving plate 27, thereby completing the adjustment of the laser 28. When the laser 28 is in motion, the corresponding rotating air outlet ring 10 and the collecting box 21 are driven to move synchronously through the connecting plate 1 29 and the connecting plate 2 31 respectively, so that the rotating air outlet ring 10 always cleans the welding slag in the engraving groove area, and when the welding slag is blown up, the welding slag in the air is collected in the collecting box 21 through the collecting box 21.

[0059] The remaining structures are the same as those of Example 1.

[0060] Example 3, reference Figure 2 as well as Fig.10 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the clamping assembly includes circular holes opened on two support plates 3, a guide tube 36 rotatably mounted on one of the circular holes, a drive tube 37 rotatably mounted on the other circular hole, a clamping tube 39 fixedly mounted on the adjacent side walls of the guide tube 36 and the drive tube 37, a plurality of mounting rods 40 fixedly mounted on the side walls of the support plate 3, a control motor 41 fixedly mounted on one end of the plurality of mounting rods 40, a transmission plate 42 fixedly mounted on the inner wall of the drive tube 37, a driving end of the control motor 41 fixedly connected to the axis of the transmission plate 42, an embossing roller 43 clamped between the two clamping tubes 39, and the embossing roller 43 passes through the interior of the sliding load-bearing ring 5. A control switch 38 is fixedly mounted on the side walls of the two support plates 3, and electric clamps (not shown) are installed in the two clamping tubes 39, and the two electric clamps are electrically connected to the corresponding control switch 38.

[0061] Specifically, the control switch 38 is used to control the electric clamp in the clamping tube 39. When the control switch 38 is turned on, the electric clamp contracts and clamps the embossing roller 43 to be installed at the center of the clamping tube 39. The stability of the clamp directly determines the accuracy and quality of the engraving. The axis of the embossing roller 43 is on the same horizontal plane as the laser head of the laser 28. The electric clamp is a prior art and will not be elaborated on here. A rubber ring is fixed on the clamp of the electric clamp. The rubber ring is used to protect the surface of the embossing roller 43 to prevent the clamp from hard contact with the embossing roller 43, resulting in scratches on the surface of the embossing roller 43, which affects the production quality and appearance. One end of the guide tube 36 is set to a large diameter, which is convenient for the staff to put the embossing roller 43 into the two clamping tubes 39 for clamping.

[0062] During use, the staff pushes the embossing roller 43 to be engraved between the two clamping tubes 39 through the guide tube 36, and turns on the corresponding control switch 38, so that the control switch 38 turns on the electric clamp, and the electric clamp fixes the two ends of the embossing roller 43 in the two clamping tubes 39 to complete the clamping of the embossing roller 43.

[0063] The remaining structure is the same as that of Example 2.

[0064] Based on Examples 1-3, a method for manufacturing an embossing roller is as follows:

[0065] S1: Use organic solvent to clean the surface of the copper-plated steel roller to remove surface impurities;

[0066] S2: Control the size of the copper-plated steel roller through reasonable machining;

[0067] S3: Determine the embossing pattern on the surface of the copper-plated steel roller;

[0068] S4: using computer-aided design of a numerical model of the pattern and importing it into the laser 28;

[0069] S5: The staff pushes the embossing roller 43 to be engraved between the two clamping tubes 39 through the guide tube 36, and turns on the corresponding control switch 38, so that the control switch 38 turns on the electric clamp, and the electric clamp fixes the two ends of the embossing roller 43 in the two clamping tubes 39, completing the clamping of the embossing roller 43;

[0070] S6: Set parameters according to factors such as steel roller material, thickness, embossing pattern depth, etc.

[0071] S7: The staff turns on the laser 28, which engraves the surface of the embossing roller 43, and turns on the small powerful fan 8 and the exhaust fan 20, and turns on the drive motor 14. The drive motor 14 drives the drive gear 16 to rotate through the drive shaft 15, and then drives the upper driven gear ring 17 to rotate through the drive gear 16. The driven gear ring 17 rotates and drives the rotating air outlet ring 10 to rotate in the ventilation ring groove 6. At the same time, the airflow generated by the small powerful fan 8 directly enters the ventilation ring groove 6 through the connecting pipe 9, and the nitrogen in the ventilation ring groove 6 is The gas flow is blown out through the blowing holes 12 on the gas outlet pipe 11. Since the rotating gas outlet ring 10 rotates continuously, the gas outlet pipe 11 rotates synchronously. The multiple gas outlet pipes 11 alternately act on the nitrogen flow in the engraving groove while rotating. At the same time, the blowing holes 12 act on the engraving groove at a certain angle. Therefore, the nitrogen blown out of the blowing holes 12 acts on the welding slag in the engraving groove in a spiral flow manner, so that the welding slag is blown up by the air flow. At the same time, the exhaust fan 20 sucks the welding slag blown in the air into the collection box 21 for collection, thereby completing the cleaning and collection of the welding slag.

[0072] S8: When the laser 28 needs to move in the horizontal direction to adjust its position during the engraving process, the push plate 33 is driven to move in the horizontal direction through the telescopic end of the cylinder 35, and the push plate 33 drives the laser 28 on its upper end to move synchronously through the driving plate 27, thereby completing the adjustment of the laser 28. When the laser 28 is in motion, the corresponding rotating air outlet ring 10 and the collecting box 21 are driven to move synchronously through the connecting plate 1 29 and the connecting plate 2 31, respectively, so that the rotating air outlet ring 10 always cleans the welding slag in the engraving groove area, and when the welding slag is blown up, the welding slag in the air is collected in the collecting box 21 through the collecting box 21;

[0073] S9: Quality inspection and assembly and debugging of the engraved steel roller.
