Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a CNC gantry engraving machine for processing magnetic rollers. Background Technology

[0002] Magnetic rollers, as a special type of roller workpiece with permanent or strong inductive magnetism, are widely used in ink transfer systems in the printing industry, positioning and conveying in packaging machinery, and various industrial automation transmission fields due to their unique magnetic adsorption properties. When performing fine surface processing, such as high-precision engraving of corporate logos, decorative textures, or functional grooves, high-performance CNC engraving machines are usually required. However, the strong magnetic field of the magnetic roller itself will quickly attract the tiny iron filings generated by cutting during the engraving process to the roller surface, especially accumulating around the area where the engraving is being performed. This not only interferes with the processing line of sight but also directly affects the accuracy of the engraving and the surface quality, becoming a major challenge in high-precision processing.

[0003] Currently, most CNC engraving machines on the market lack dedicated chip removal and anti-chip functions for magnetic roller workpieces. Although some models have added simple protective covers or pneumatic blowing systems to attempt to blow chips away from the processing area, the continuous magnetic force still results in incomplete chip removal and re-adsorption. Accumulated metal chips can easily scratch the processed or unprocessed roller surfaces. More seriously, the chips can be carried into the cutting zone by the rotating tool, causing tool vibration, pattern misalignment, and dimensional deviations. This also accelerates tool wear, potentially leading to chipping or breakage, severely impacting equipment lifespan and processing efficiency. Summary of the Invention

[0031] Furthermore, a second electric telescopic mechanism (not shown in the figure) is installed inside the fixed box 8. The end of the second electric telescopic mechanism is threadedly fixed to the movable block 5. The second electric telescopic mechanism is used to control the lateral movement of the movable block 5 on the fixed box 8.

[0032] Inside the machine tool 1, two connecting rods 13 are installed on both sides of the lead screw 15 via couplings. Several mounting plates 14 are welded to the inner bottom of the machine tool 1. The surface of the mounting plates 14 has through holes corresponding to the connecting rods 13 and the lead screw 15, which are used to limit the connecting rods 13 and the lead screw 15.

[0033] The movable plate 4 is provided with a positioning plate 6, and positioning holes 19 are provided around the perimeter of the positioning plate 6. The movable plate 4 is provided with a positioning groove corresponding to the positioning holes 19, and the positioning holes 19 and the positioning groove are adapted to each other.

[0034] The positioning plate 6 has a groove 18, and a limiting plate 23 is welded on the groove 18. A circular hole is opened in the middle of the limiting plate 23, and a limiting ring 26 is abutted in the circular hole. The diameter of the limiting ring 26 is adapted to the shaft head of the magnetic roller. An inner hole is opened on one side of the groove 18, and a moving rod 36 is slidably arranged in the inner hole. A movable frame 24 is welded to the end of the moving rod 36, and a collar 25 is threaded on the movable frame 24. The collar 25 and the limiting ring 26 are coaxially arranged.

[0035] Specifically, the positioning plate 6 is equipped with an electric push rod (not shown in the figure) for driving the moving rod 36 to move.

[0036] Furthermore, there are two collars 25 with a gap between them. The diameter of the collars 25 is larger than the diameter of the magnetic roller, and the adjacent sides of the two collars 25 are inclined towards the central axis.

[0037] The inner surface of one adjacent end of each of the two rings 25 is provided with a first annular groove. A brush 37 is installed in the first annular groove. The brush 37 is arranged in a ring. The end of the brush 37 is in contact with the magnetic roller. The brush 37 is made of flexible material.

[0038] An installation rod 21 is welded to the upper surface of the groove 18. A baffle 22 is hinged to the bottom of the installation rod 21. A collection groove 20 is also provided in the groove 18, and the installation rod 21 is located at the top of the collection groove 20.

[0039] Furthermore, the connection between the collection trough 20 and the groove 18 is set as an arc surface, and a gap is left between the bottom of the baffle 22 and the collection trough 20.

[0040] The engraving assembly includes a groove 29 on both sides of the inner sidewall of the movable block 5. A sliding plate 30 is slidably disposed in the groove 29. A movable seat 28 is welded to the top of the sliding plate 30. A connecting post 33 is threadedly installed at the bottom of the movable seat 28, and a base 35 is installed through the connecting post 33. An air outlet 39 is opened at the bottom of the base 35. A connecting frame 31 is also installed on the sliding plate 30. A second drive motor is disposed on the connecting frame 31. An engraving cutter 34 is installed at the output end of the second drive motor through a coupling.

[0041] Furthermore, the base 35 has a hollow interior.

[0042] The movable block 5 is equipped with a first electric telescopic mechanism (not shown in the figure), which is used to drive the sliding plate 30 to move up and down.

[0043] Furthermore, a fixing frame 10 is welded and installed on the top of the movable block 5, and a second cable chain 12 is installed between the fixing frame 10 and the top of the movable block 5. A first cable chain 11 is installed on one side of the movable block 5, and the other end of the first cable chain 11 is connected to one side wall of the fixing frame 10. The first cable chain 11 and the second cable chain 12 are used to protect the cables and pipes connected to the movable block 5.

[0044] Furthermore, a third protective cover 27 is fixedly installed between the movable base 28 and the movable block 5. The first protective cover 2, the second protective cover 7, and the third protective cover 27 are all used to prevent waste from entering the working element area.

[0045] Working principle:

[0046] When using this gantry engraving machine, the magnetic roller to be processed is placed on the positioning plate 6, and the shaft end of the magnetic roller is sent into the limiting ring 26 and sleeved with the limiting plate 23 to ensure radial positioning. The movable frame 24 is moved by the electric push rod, which in turn moves the collar 25. The inner wall of the collar 25 does not contact the surface of the magnetic roller. The area between the two collars 25 is set as the working range of the engraving component. The movable frame 24 is moved by the electric push rod, which in turn moves the collar 25 to adjust the engraving range and prevent iron filings from splashing and adhering to the surface of the magnetic roller during engraving, thus affecting the processing operation.

[0047] The positioning holes 19 around the positioning plate 6 are matched with the positioning grooves on the movable plate 4 to achieve quick installation and fixation of the positioning plate 6. The first drive motor drives the fixed block 16 to move through the lead screw 15. The fixed block 16 drives the movable plate 4 and the positioning plate 6 on it to move through the connecting plate 17 to achieve the lateral feeding of the magnetic roller. The first electric telescopic machine drives the sliding plate 30 to move. The movement of the sliding plate 30 drives the movable seat 28 to move down, realizing the up and down movement of the engraving knife 34. The second electric telescopic machine drives the movable block 5 to move laterally on the fixed box 8.

[0048] When the positioning plate 6 moves below the engraving knife 34, the second drive motor drives the engraving knife 34 to rotate and perform magnetic roller engraving. At the same time, the second electric telescopic motor drives the movable block 5 to move laterally, and the electric push rod drives the movable frame 24 and the collar 25 installed on the movable frame 24 to move accordingly, so as to ensure that the engraving knife 34 is always between the two collars 25 and performs engraving on the magnetic roller in the middle of the collars 25.

[0049] Furthermore, a fan is installed inside the fixed box 8 via internal threads. The fan is connected to the air inlet pipe 32. An air outlet 39 at the bottom of the base 35 takes in air through the air inlet pipe 32. The air outlet 39 is positioned towards the mounting rod 21, blowing the iron filings toward the side of the baffle 22. The bottom of the baffle 22 moves above the collection trough 20, forming an opening between the collection trough 20 and the baffle 22. The iron filings move toward the baffle 22 under the influence of gravity and wind. After the iron filings hit the baffle 22, the baffle 22 guides the iron filings, causing them to fall into the collection trough 20. This prevents the iron filings from sticking to the magnetic roller and affecting the processing operation of the magnetic roller itself. At the same time, the first protective cover 2, the second protective cover 7, and the third protective cover 27 respectively cover the area of ​​the lead screw 15, the fixed box 8, and the engraving assembly to prevent waste from entering critical components.

[0050] Furthermore, during the processing of the magnetic roller, iron filings are generated during the engraving process. Due to the magnetism of the magnetic roller, the iron filings easily adhere to the roller surface, especially near the engraving area. Although the design includes an air outlet 39 on the collar 25 and the base 35 to prevent iron filings from adhering, in actual processing, the iron filings may not be completely blown away or collected. To monitor the surface of the magnetic roller in real time, a high-precision camera facing the engraving cutter 34 is installed on the movable block 5 to collect data on the surface of the magnetic roller at the engraving cutter 34.

[0051] Meanwhile, a second annular groove is provided on the surface of the collar 25, and a demagnetizer coil 40 is placed in the second annular groove. This is used to perform local temporary demagnetization during the engraving process of the engraving knife 34 on the magnetic roller between the collar 25, so as to prevent iron filings from being directly adsorbed on both sides of the processing area during the operation of the engraving knife 34.

[0052] The demagnetizer coil 40 on the collar 25 is connected to the same control board 9. At this time, the program is set to start the demagnetizer synchronously when the engraving knife 34 descends to contact the workpiece and begins engraving; and to turn off the demagnetizer when the engraving knife 34 is lifted or moved to a non-processing area.

[0053] Controlled by the demagnetizer coil 40 and the control board 9, and combined with the air outlet 39 on the base 35, iron filings are blown into the collection tank 20, preventing them from affecting normal engraving operations. This further prevents iron filings from being rolled between the engraving knife 34 and the workpiece, thus preventing scratches and precision loss on the surface of the magnetic roller caused by iron filings, and ensuring the clarity and smoothness of the engraved pattern.

[0054] The system collects real-time data on the carving knife 34 and the area above the positioning plate 6 using a high-precision camera, and then analyzes the data.

[0055] If the system detects through the camera that iron filings still exist on the two collars 25 after the engraving knife 34 has been working for a period of time, it controls the fan to increase the air intake to ensure that the iron filings on the collars 25 are blown into the collection groove 20. If the fan increases the blowing force but cannot blow the iron filings off the collars 25, it proves that the demagnetizing coil 40 has insufficient demagnetizing ability. Then, it controls the demagnetizer to increase the power to improve the demagnetizing ability and reduce the magnetic attraction ability of the magnetic roller in this area.

[0056] Furthermore, during the engraving operation of the engraving knife 34, the rotation of the engraving knife 34 will cause iron filings to enter the collar 25 through the gap, and there is a possibility that the iron filings will be attracted to the magnetic roller inside the collar 25.

[0057] The brush 37, which is arranged in an inner ring of the collar 25, always maintains contact with the magnetic roller, effectively preventing externally splashed iron filings from entering the engraving area, and also preventing iron filings blown up in the engraving area from escaping to other areas.

[0058] Furthermore, by cooperating with the fan, the iron chips generated during engraving are ensured to move toward the baffle 22 and the collection groove 20, thereby improving the chip removal efficiency.

[0059] In particular, even if a small amount of iron filings are magnetically attracted to the magnetic roller body outside the moving path of the collar 25, they will be scraped away by the moving brush 37 to prevent the iron filings from affecting the processing environment of the engraving knife 34, while protecting the non-processing area of ​​the magnetic roller.

[0060] During use, the engraving knife 34 generates heat through friction with the surface of the magnetic roller. The accumulation of heat may cause the temperature of the magnetic roller to rise, especially when the engraving depth is large or the feed speed is fast, the temperature change is particularly prominent. Magnetic materials are sensitive to temperature, and high temperature may cause demagnetization or changes in magnetic properties.

[0061] Therefore, we optimized the air intake system by adding a diverter pipe 38 to the air intake pipe 32. The diverter pipe 38 extends to one side of the engraving blade 34. Furthermore, the diverter pipe 38 is positioned towards the end of the engraving blade 34 to cool down the air and guide the direction of the metal chips.

[0062] During the processing of the magnetic roller, the air outlet 39 and the diversion pipe 38 are connected to the fan through the air inlet pipe 32. The airflow blows towards the baffle 22 and the collection tank 20 to guide the iron filings generated on the surface of the magnetic roller due to the engraving operation into the collection tank 20. At the same time, the brush 37 set on the collar 25 is used to prevent iron filings from entering the area at the bottom of the collar 25. The diversion pipe 38 is also set towards one side of the collection tank 20.

[0063] The camera monitors the area in real time, and the control board 9 analyzes the working depth and rotation speed of the engraving knife 34 to further control the fan airflow.

[0064] Furthermore, since the engraving knife 34 generates heat due to friction with the magnetic roller, a temperature sensor is installed on the collar 25 to monitor the temperature at the working point of the engraving knife 34. If the temperature is higher than the normal operating range, the camera collects data on the engraving knife 34. If the surface of the engraving knife 34 is curled, the engraving operation is paused, the engraving knife 34 is replaced, and the engraving operation is resumed. If the engraving knife 34 is intact and has no gaps or curling, the air volume is increased by the fan, and the diverter pipe 38 and the air outlet 39 continue to work. The diverter pipe 38 increases the airflow to force heat dissipation at the engraving point, reducing the heat generated by the friction between the engraving knife 34 and the roller surface. The air outlet 39 increases the airflow to control the hot iron filings to blow away and prevent heat accumulation on the roller surface.

[0065] Furthermore, if the camera detects an increase in iron filings residue, this situation may cause the magnetic roller to change its magnetism due to high temperature. At this time, the control board 9 controls the fan to increase the fan volume to enhance cooling and cleaning. Furthermore, the control board 9 controls the demagnetizer coil 40 to increase the power for further demagnetization.

[0066] During the processing, the output of iron filings is closely related to the feed speed and carving depth of the engraving cutter 34. The faster the engraving cutter 34 is, the higher the material removal rate per unit time, and the greater the amount of iron filings produced; the deeper the carving depth, the greater the amount of material removed in a single cut, and the greater the amount of iron filings produced. Therefore, to ensure the normal operation of the engraving cutter 34, when the control board 9 controls the operation of the engraving cutter 34, the fan adjusts the air volume according to the working process of the engraving cutter 34. When the carving depth increases, the fan increases the air volume; when the speed of the engraving cutter 34 increases, the fan also adjusts the air volume accordingly.

[0067] Furthermore, the control of airflow and engraving knife 34 by control board 9 is based on the prediction of ideal conditions. The actual iron filings are also affected by the wear of engraving knife 34 and the demagnetizing ability of demagnetizer coil 40.

[0068] If the end of the engraving cutter 34 is damaged, and the camera detects an increase in the number of iron filings on the surface, and the temperature sensor detects an increase in the surface temperature of the magnetic roller, it is determined that the engraving cutter 34 is damaged and needs to be replaced.

[0069] With the carving knife 34 intact, the camera continuously monitors the area near the carving point and the collar 25 for any remaining iron filings. The control board 9 controls the fan to increase the airflow. If the camera still detects iron filings adhering after increasing the airflow, the control board 9 determines that the problem is not insufficient airflow, but rather excessive magnetic attraction. The system will prioritize or simultaneously increase the power of the demagnetizer coil 40 to weaken the adsorption of iron filings at the source, and then supplement it with an airflow that is larger than ideal for blowing.

[0070] At the start of engraving, the control board 9 synchronously activates the demagnetizer coil 40 and the fan, the collar 25 moves with the engraving cutter 34, and the airflow is ejected through the splitter pipe 38. Throughout the process, the real-time temperature is fed back by sensors, and the processing position is collected in real time by a camera, allowing the control board 9 to adjust variable parameters according to the actual situation to achieve better engraving operations.

[0071] Furthermore, the workflow of this CNC gantry engraving machine during use is as follows:

[0072] S1. Select the collar 25 according to the required magnetic roller diameter. The inner diameter of the collar 25 must be larger than the magnetic roller diameter. Install the collar 25 to the movable frame 24 by thread. Fix the magnetic roller to the limiting ring 26. Then fix the positioning plate 6 to the movable plate 4 by thread. Drive the lead screw 15 through the first drive motor to move the magnetic roller to the bottom of the engraving assembly to prepare for engraving.

[0073] S2, the control board 9 controls the carving knife 34 to start descending, and at the same time controls the demagnetizer coil 40 to start synchronously, forming a local demagnetization area near the carving knife 34, so that the iron chips generated by carving are free due to the lack of magnetic attraction. The iron chips are directed towards the baffle 22 and the collection tank 20 by the fan and the air outlet 39. After the iron chips hit the baffle 22, they lose kinetic energy and fall into the arc-shaped collection tank 20 under the action of gravity.

[0074] S3. Protective operation is performed by using the collar 25 and the brush 37 set in the inner ring of the collar 25 to prevent iron filings from entering the working area outside the two collars 25. The movable frame 24 is driven by the electric push rod to move laterally with the engraving knife 34 to ensure that the two collars 25 are always located on both sides of the engraving knife 34 during the processing. The surface is continuously scraped by the brush 37 and the demagnetizer works continuously to ensure that iron filings are kept away from the processing area, thus completing the magnetic roller processing operation.
