Description

Technical Field

[0001] This invention relates to the field of ceramic anilox roller laser engraving equipment technology, specifically a rapid trial engraving fixture for ceramic anilox roller laser engraving with synchronous reference and air-cooled dust removal. Background Technology

[0002] Ceramic anilox rollers are core precision components of flexible printing and coating equipment. The cell parameters formed on their surface by laser engraving directly determine the uniformity and precision of printing and coating. Before formal engraving processing of each batch of anilox rollers with different mesh counts (LPI), trial engraving operations must be performed on ceramic test blocks of the same material to calibrate core process parameters such as laser power, scanning speed, focal height, cell depth, and ink load. Only after the parameters pass the test can finished roller engraving production begin to avoid large-scale scrapping of finished products.

[0003] Currently, the industry commonly uses a simple clamping method for trial engraving operations. Long ceramic test blocks are fixed to the surface of the finished anilox roller or the machine tool worktable by means of binding, magnetic attraction, or mechanical clamping. This method has many inherent defects: First, the clamping and disassembly process is cumbersome, with each clamping taking 5-15 minutes. Frequent machine adjustments and specification changes will occupy a lot of equipment production time and significantly reduce the uptime of the engraving machine. Second, the simple clamping cannot ensure that the test block and the finished roller are on the same cylindrical reference plane. There is a height difference between the test block and the roller surface, which causes the laser focus to shift. The cell parameters obtained from the trial engraving deviate significantly from the formal processing data, making the test calibration ineffective and easily leading to the scrapping of the finished product.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a rapid trial engraving fixture for laser engraving of ceramic anilox rollers with synchronous reference and air-cooled dust removal. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid trial engraving fixture for laser engraving of ceramic anilox rollers with synchronous reference and air-cooled dust removal, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid trial engraving fixture for laser engraving of ceramic anilox rollers with synchronous reference and air-cooled dust removal, comprising an auxiliary frame and a platform. The auxiliary frame is internally provided with a drive assembly for auxiliary linkage, and the drive assembly includes a spindle quick-release base, a drive gear, and a transmission gear. The spindle quick-release base is internally provided with a drive gear, and a transmission gear is meshed on one side of the drive gear. A spindle sleeve is provided at the middle of one end of the spindle quick-release base, and the spindle sleeve is detachably fixed to any end of the spindle tip of the engraving machine via a tapered expansion sleeve. An annular positioning boss is installed on the other side of the spindle quick-release base. A hollow rotating support shaft is provided at the middle of one end of the transmission gear, and a cross positioning groove is opened at the end of the hollow rotating support shaft. A cross positioning key is installed inside the cross positioning groove, and the platform is located at the bottom of the cross positioning key.

[0007] Furthermore, the platform has an embedded test block slot inside, and the test block slot is equipped with a limiting component for auxiliary positioning.

[0008] Furthermore, the limiting component includes a magnetic strip, a spring pressure plate, and a spring, and the surface of the magnetic strip is equipped with a spring pressure plate, and a spring is provided on one side of the spring pressure plate.

[0009] Furthermore, the outer surface of the hollow rotary support shaft is provided with a positioning component for axial positioning, and three sets of positioning components are installed.

[0010] Furthermore, the positioning assembly includes a connecting plate, a pressure rod, a rubber pad, and a pressure plate, with the pressure rod threaded onto the internal threads of the connecting plate, a pressure plate rotatably mounted at the end of the pressure rod, and a rubber pad mounted on one side of the surface of the pressure plate.

[0011] Furthermore, the platform has an embedded annular tangential air duct inside, with one end of the annular tangential air duct connected to a pneumatic rotary joint and the other end of the annular tangential air duct connected to a negative pressure device.

[0012] Furthermore, the auxiliary frame has a hollow interior structure, and both the upper and lower parts of the auxiliary frame are fitted with cover plates.

[0013] Furthermore, a rotating shaft is provided in the middle of the transmission gear, and a fixing plate is rotatably mounted at the end of the rotating shaft.

[0014] Furthermore, the stage has a replaceable modular structure, including a single-slot stage and a three-slot stage. The single-slot stage is used for calibration of a single process parameter, while the three-slot stage is used for simultaneous testing of multiple mesh sizes using LPI. Furthermore, the other end of the annular tangential air duct is connected to a negative pressure dust collection pipe, which is externally connected to a negative pressure device for suctioning ceramic alumina dust generated during engraving.

[0015] This invention provides a rapid trial engraving fixture for laser engraving of ceramic anilox rollers with synchronous reference and air-cooled dust removal, which has the following beneficial effects: 1. This invention achieves rapid overall installation through the main shaft sleeve and the conical expansion sleeve. The platform is positioned by the insertion of the cross positioning groove and the cross positioning protrusion key, and the axial locking is completed with the positioning component. The platform can be quickly disassembled and the specifications can be changed. The annular positioning boss replicates the outer circle reference of the finished anilox roller, ensuring that the ceramic test carving block and the finished roller are on the same cylindrical processing surface. The gear transmission component ensures that the speed and angle of the hollow rotating support shaft are completely synchronized with the spindle speed and the engraving machine, eliminating focal length, linear speed and angle deviations. The test carving process parameters are true and reliable, reducing the risk of scrapping the finished roller.

[0016] 2. This invention utilizes an internal limiting component within the test block slot, consisting of a magnetic strip, spring pressure plate, and spring combination, to achieve self-centering clamping of the ceramic test block. This eliminates the need for bolts, allowing for easy test block mounting and dismounting. A pre-embedded annular tangential air duct within the platform facilitates tangential air cooling via a pneumatic rotary joint. Combined with a negative pressure dust extraction system, this effectively removes laser engraving heat, inhibiting thermal deformation and chipping / erosion of the test block. Simultaneously, it collects alumina dust, protecting the machine tool guideways and laser lens. The use of small-sized standardized ceramic test blocks significantly improves material utilization compared to traditional long strip test blocks, effectively reducing ceramic consumable consumption. The entire fixture is directly compatible with the existing spindle center of the engraving machine, requiring no modification to the machine tool itself, thus offering strong versatility.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the invention.

[0020] like Figures 1-6As shown, a rapid trial engraving fixture for laser engraving of ceramic anilox rollers with synchronous reference and air-cooled dust removal includes an auxiliary frame 1, a cover plate 2, a spindle sleeve 3, a drive assembly 4, a spindle quick-release base 401, a drive gear 402, a transmission gear 403, a fixing plate 5, a rotating shaft 6, a positioning assembly 7, a connecting plate 701, a pressure rod 702, a rubber pad 703, a pressure plate 704, an annular positioning boss 8, a hollow rotating support shaft 9, a cross positioning groove 10, and a cross positioning key 11. The auxiliary frame 1 includes a platform 12, a pneumatic rotary joint 13, a negative pressure dust removal pipe 14, a test block slot 15, a limiting component 16, a magnetic strip 1601, a spring pressure plate 1602, and a spring 1603. The auxiliary frame 1 contains a drive assembly 4 for auxiliary linkage. The drive assembly 4 includes a spindle quick-release base 401, a drive gear 402, and a transmission gear 403. A rotating shaft 6 is located in the middle of the transmission gear 403, and a fixing plate 5 is rotatably mounted at the end of the rotating shaft 6. The internal structure is hollow, and the upper and lower ends of the auxiliary frame 1 are fitted with cover plates 2. The auxiliary frame 1 provides external protection for the entire drive assembly 4. The cover plates 2 fitted at the upper and lower ends of the hollow auxiliary frame 1 provide dust protection for the internal transmission mechanism. The spindle quick-release base 401 is equipped with a drive gear 402, and a transmission gear 403 is meshed on one side of the drive gear 402. A spindle sleeve 3 is provided in the middle of one end of the spindle quick-release base 401, and the spindle sleeve 3 is connected to... The tapered expansion sleeve can be detachably fixed to any end of the top of the engraving machine spindle. The other side of the spindle quick-release base 401 is equipped with an annular positioning boss 8. The spindle quick-release base 401 is detachably fixed to the top of the engraving machine spindle by the spindle sleeve 3 and the tapered expansion sleeve. When the engraving machine spindle rotates, it drives the spindle quick-release base 401 to rotate synchronously. The drive gear 402 inside the drive assembly 4 rotates together with the spindle quick-release base 401. The drive gear 402 meshes and drives the transmission gear 403 to rotate.The transmission gear 403 rotates around the shaft 6, and the fixed plate 5 provides rotational support for the shaft 6, transmitting power to the hollow rotating support shaft 9. This ensures that the hollow rotating support shaft 9 achieves the same rotational speed and angle as the main spindle of the engraving machine, guaranteeing that the rotational linear speed, cell processing angle, and finished ceramic anilox roller processing conditions remain synchronized during the trial engraving. The outer diameter of the annular positioning boss 8 on the quick-release base 401 of the main spindle is equal to the outer diameter of the finished ceramic anilox roller, thus establishing a unified cylindrical processing benchmark. This ensures that the working surface of the trial engraving block and the surface of the finished roller are on the same benchmark, eliminating the problem of laser focal length offset. The hollow rotating support shaft 9 is located at the middle of one end of the transmission gear 403, and a cross positioning groove 10 is provided at the end of the hollow rotating support shaft 9. The outer surface of the hollow rotating support shaft 9 is provided with a groove for axial positioning. The positioning component 7 is provided in three sets. The positioning component 7 includes a connecting plate 701, a pressure rod 702, a rubber pad 703, and a pressure plate 704. The pressure rod 702 is installed on the internal thread of the connecting plate 701. The pressure plate 704 is rotatably mounted at the end of the pressure rod 702. The rubber pad 703 is installed on one side of the surface of the pressure plate 704. The specification can be changed by locking the positioning component 7 without modifying other parts. The platform 12 has an embedded test block slot 15. The limiting component 16 in the slot realizes the automatic positioning and fixing of the ceramic test block. The magnetic strip 1601 in the limiting component 16 provides adsorption and positioning for the ceramic test block. The spring 1603 drives the spring pressure plate 1602 to apply a pre-tightening force to the side of the test block, realizing the self-centering clamping of the test block. The test block can be pre-fixed without bolts. After installation, the multiple positioning components 7 mounted on the outside of the hollow rotary support shaft 9 perform axial locking. Rotating the pressure rod 702 of the positioning component 7 causes it to feed along the thread of the connecting plate 701, pushing the pressure plate 704 to press against the end face of the platform 12. The rubber pad 703 on the pressure plate 704 acts as a buffer and anti-slip agent, limiting the axial movement of the platform 12, thus completing the locking of the platform 12. After the trial carving is completed, rotating the pressure rod 702 in the opposite direction releases the platform 12, allowing it to be directly pulled out for test block replacement or platform 12 specification replacement. A cross-shaped positioning key 11 is installed inside the cross-shaped positioning groove 10, and the platform 12... Located at the bottom of the cross-shaped positioning key 11, a cross-shaped positioning groove 10 is formed on the end face of the hollow rotating support shaft 9. The cross-shaped positioning key 11 on the back of the stage 12 is inserted into the cross-shaped positioning groove 10. The keyway cooperation completes the circumferential positioning of the stage 12, preventing circumferential angular displacement. The stage 12 is a replaceable modular structure, available in single-slot and triple-slot specifications. The single-slot stage 12 is used when a single process parameter calibration is required, while the triple-slot stage 12 is used when multiple mesh size LPI synchronous tests are required simultaneously. The compatible ceramic sample block size is 10×20×0.8–1.2mm. During replacement, simply loosen the positioning component 7, directly pull out the old stage 12 along the cross-shaped positioning groove 10, and insert the cross-shaped positioning key 11 of the other stage 12 into the cross-shaped positioning groove 10.

[0021] like Figure 1 , Figure 5 and Figure 6 As shown, the platform 12 has an embedded test block slot 15 inside, and a limiting component 16 for auxiliary limiting is provided inside the test block slot 15. The limiting component 16 includes a magnetic strip 1601, a spring pressure plate 1602, and a spring 1603. The surface of the magnetic strip 1601 is equipped with a spring pressure plate 1602, and a spring 1603 is provided on one side of the spring pressure plate 1602. An annular tangential air duct is pre-embedded inside the platform 12. One end of the annular tangential air duct is connected to a pneumatic rotary joint 13, and the other end of the annular tangential air duct is connected to a negative pressure device. The platform 12 has an annular tangential air duct pre-embedded inside, and one end of the air duct is connected to the pneumatic rotary joint 13 to receive compressed air. The compressed air is directed along the tangential direction. The engraving area of ​​the ceramic test block is blown away to remove the heat generated by laser engraving, thus inhibiting thermal deformation and chipping / erosion of the test block. The other end of the air duct is connected to the negative pressure dust removal pipe 14, which is connected to an external negative pressure device. The ceramic alumina dust generated during engraving is drawn and collected under negative pressure, preventing dust from contaminating the machine tool guide rail and laser lens. The engraving machine spindle drives the entire set of fixtures to rotate synchronously. The laser performs laser engraving on the ceramic test block inside the test block slot 15 according to preset parameters. After the test engraving is completed, the pressure rod 702 of the positioning component 7 is loosened, and the stage 12 can be pulled out to remove the test block for testing the cell parameters. After all parameters are adjusted, the conical expansion sleeve is loosened, and the entire set of fixtures is removed from the center of the engraving machine spindle. The machine tool resumes the finished anilox roller engraving operation.

[0022] In summary, this rapid trial engraving fixture for ceramic anilox roller laser engraving with synchronous reference and air-cooled dust removal firstly, based on... Figures 1-6The structure shown firstly involves the spindle quick-release base 401 being detachably fixed to the tip of the engraving machine spindle via a spindle sleeve 3 and a tapered expansion sleeve. When the engraving machine spindle rotates, it drives the quick-release base 401 to rotate synchronously. The drive gear 402 inside the drive assembly 4 rotates along with the quick-release base 401, and the drive gear 402 meshes with and drives the transmission gear 403 to rotate. The transmission gear 403 rotates around the rotating shaft 6, and the fixing plate 5 provides rotational support for the rotating shaft 6, transmitting power to the hollow rotating support shaft 9. This ensures that the hollow rotating support shaft 9 achieves the same rotational speed and angle as the engraving machine spindle, guaranteeing synchronization of the rotational linear speed, cell processing angle, and finished ceramic anilox roller processing conditions during trial engraving. The auxiliary frame 1 provides external protection for the entire drive assembly 4. The upper and lower ends of the hollow auxiliary frame 1 are fitted with cover plates 2 to provide dust protection for the internal transmission mechanism. The outer diameter of the annular positioning boss 8 on the spindle quick-mount base 401 is equal to the outer diameter of the ceramic anilox roller to be processed, thus establishing a unified cylindrical machining datum and ensuring that the working surface of the test block and the surface of the finished roller are on the same datum, eliminating the problem of laser focal length offset. A cross positioning groove 10 is opened on the end face of the hollow rotary support shaft 9. The cross positioning protrusion 11 on the back of the stage 12 is inserted into the cross positioning groove 10. The circumferential positioning of the stage 12 is completed by the keyway cooperation, preventing the stage from shifting circumferentially. The stage 12 is a replaceable modular structure, with single-slot and triple-slot specifications. When a single process parameter calibration is required, the single-slot stage 12 is selected. When multiple mesh size LPI synchronous tests are required, the triple-slot stage 12 is used. The size of the ceramic test block is 10×20×0.8–1.2mm. When replacing, simply loosen the positioning component 7, pull out the old stage 12 along the cross positioning groove 10, align the cross positioning protrusion 11 of the other stage 12 with the cross positioning groove 10 and insert it into place, then lock it with the positioning component 7 to complete the specification switch. No other parts need to be modified. The stage 12 has an embedded test block slot 15 inside, and the limiting component 16 in the slot realizes the automatic positioning and fixing of the ceramic test block. The magnetic strip 1601 in the limiting component 16 provides adsorption and positioning for the ceramic test block, and the spring 1603 drives the spring pressure plate 1602 to apply a pre-tightening force to the side of the test block to complete the self-centering clamping of the test block. The test block can be pre-fixed without bolts.After installation, the multiple positioning components 7 mounted on the outside of the hollow rotary support shaft 9 perform axial locking. Rotating the pressure rod 702 of the positioning component 7 causes the pressure rod 702 to feed along the thread of the connecting plate 701, pushing the pressure plate 704 to press against the end face of the platform 12. The rubber pad 703 on the pressure plate 704 acts as a buffer and anti-slip agent, limiting the axial movement of the platform 12, thus completing the locking of the platform 12. After the trial carving is completed, rotating the pressure rod 702 in the opposite direction releases the platform 12, allowing the platform 12 to be directly pulled out to replace the test block or the specifications of the platform 12. The platform 12 has a pre-embedded annular tangential air duct inside, with one end of the air duct connected to a pneumatic rotary joint 13 to supply compressed air. The compressed air blows along the tangential direction to carve the ceramic test block. The engraving area removes the heat generated by laser engraving, inhibiting thermal deformation of the test block and chipping and ablation of the mesh. The other end of the air duct is connected to the negative pressure dust removal pipe 14 and external negative pressure equipment. The ceramic alumina dust generated during engraving is drawn and collected under negative pressure, preventing dust from contaminating the machine tool guide rail and laser lens. The engraving machine spindle drives the entire set of fixtures to rotate synchronously. The laser performs laser engraving on the ceramic test block inside the test block slot 15 according to preset parameters. After the test engraving is completed, the pressure rod 702 of the positioning component 7 is loosened, and the carrier 12 is pulled out to remove the test block to check the mesh parameters. After all parameters are adjusted, the conical expansion sleeve is loosened, and the entire set of fixtures is removed from the top of the engraving machine spindle. The machine tool resumes the finished anilox roller engraving operation.
