Description

Technical Field

[0001] The present application relates to the technical field of intaglio printing cylinder processing, and particularly relates to a milling tool for an intaglio printing cylinder. Background Art

[0002] Gravure printing is a high-precision and high-quality printing process. Minute pits (cells) engraved on the surface of the gravure printing cylinder are used to store ink, and the graphics and texts are transferred to the printing substrate through pressure. Its printed products have the characteristics of thick ink layer, bright color, rich levels, high printing resistance, etc., and are widely used in the fields of packaging, decoration, anti-counterfeiting, etc.

[0003] Among them, the gravure printing cylinder is the core component in gravure printing. Especially the cells on its surface have a large processing precision requirement, so the processing difficulty increases accordingly. Currently, when processing some large-format gravure printing cylinders (such as decorative printing cylinders), it is necessary to first machine the macroscopic texture (such as thick lines, grooves) on its surface through a milling machine, and then complete the cells on its surface through fine engraving.

[0004] However, during the rough machining of the gravure printing cylinder by the milling machine, the generated chips are likely to remain on the surface of the gravure printing cylinder. If the machine is stopped to remove them, the processing efficiency of the gravure printing cylinder will be affected. If the chips are not removed without stopping the machine, the quality of subsequent finish machining will be affected. Summary of the Invention

[0029] The following Figures 1-4 is a further detailed description of the present application.

[0030] An embodiment of the present application discloses a milling tool for an intaglio printing plate cylinder, which is used for milling the surface of the intaglio printing plate cylinder to form lines and grooves with required shapes by rough machining.

In this embodiment, preferably, the first driving member 22 is a servo motor; and preferably, the first driving member 22 drives the sliding seat 21 to slide by means of a screw drive; since both the servo motor and the screw drive are common prior arts, they will not be elaborated here, and only a brief representation is made for them in the drawings.

[0035] The lifting table 23 is movably installed on the top of the sliding seat 21, and its moving direction is parallel to the height direction of the machine body 1; the second driving member 24 is fixedly installed on the sliding seat 21, and it is used to drive the lifting table 23 to move relative to the sliding seat 21. In this embodiment, preferably, the second driving member 24 is a servo cylinder, and its piston rod is fixedly connected to the lifting table 23; since the servo cylinder is a common prior art, it will not be elaborated here, and only a brief representation is made for it in the drawings.

[0036] The milling cutter 25 is rotatably installed on the lifting table 23 and is located above the machine body 1, and its rotation axis is parallel to the moving direction of the lifting table 23; the third driving member 26 is fixedly installed on the top of the lifting table 23, and it is used to drive the milling cutter 25 to rotate relative to the lifting table 23. In this embodiment, preferably, the third driving member 26 is a servo motor.

[0037] The spray head 27 is fixedly installed on the lifting table 23 and is located on one side of the milling cutter 25, and it is used to spray coolant downward to cool down the milling cutter 25 and the position of the gravure cylinder 5 being milled during the milling process, and at the same time, it can wash away the chips generated during the milling process on the surface of the gravure cylinder 5. In this embodiment, preferably, the spray direction of the spray head 27 is inclined downward towards the direction close to the milling cutter 25, and preferably, the spray head 27 is externally connected with a hose for providing coolant for it; since the spray head 27 with the above functions is a common prior art, it will not be elaborated here, and only a brief representation is made for it in the drawings.

[0038] Refer to Figure 1 and Figure 3 , the positioning device 3 is also installed on the top of the machine body 1, and the gravure cylinder 5 is installed and positioned on the machine body 1 through the positioning device 3. At this time, the axis of the gravure cylinder 5 is parallel to the length direction of the machine body 1, and the milling cutter 25 is located above the gravure cylinder 5 and is aligned with the axis of the gravure cylinder 5 in the vertical direction.

[0039] The positioning device 3 includes two movable seats 31, two clamps 32 and a fourth driving member 33.

[0040] The two movable seats 31 are respectively installed at both ends of the machine body 1 in the length direction, and are movably connected to the machine body 1 in the vertical direction, and the two movable seats 31 move synchronously and in the same direction relative to the machine body 1; the two clamps 32 correspond to the two movable seats 31 one by one, and the clamp 32 can be detachably connected to one end of the gravure cylinder 5 in the axial direction; the clamp 32 is rotatably installed on the corresponding movable seat 31, and is located on the side of the corresponding movable seat 31 close to the other movable seat 31, and its rotation axis is parallel to the length direction of the machine body 1 and coincides with its own axis; the fourth driving member 33 is fixedly installed on one side of a movable seat 31 facing away from the corresponding clamp 32, and is used to drive the adjacent clamp 32 to rotate relative to the corresponding movable seat 31. After both ends of the gravure cylinder 5 in the axial direction are respectively connected to the two clamps 32, the axis of the gravure cylinder 5 will coincide with the rotation axis for driving the clamp 32 to rotate by the fourth driving member 33. In this embodiment, it is preferably that the fourth driving member 33 is a servo motor; since the clamp 32 with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0041] At this time, when the gravure cylinder 5 is installed and positioned on the positioning device 3 (that is, both ends of the gravure cylinder 5 in the axial direction are respectively clamped and positioned by the two clamps 32), by controlling the fourth driving member 33 to drive the gravure cylinder 5 to rotate and cooperate with the milling device 2, the milling process of the surface of the gravure cylinder 5 can be completed.

[0042] Refer to Figure 2 and Figure 3 , a space for installing the chip removal device 4 is left below the position of the machine body 1 after the installation of the gravure cylinder 5. The chip removal device 4 includes a liquid collecting box 41, a liquid storage box 42, a filter element 43, a chip collecting box 44, a plurality of chip removal brushes 45 and a flow pusher 46. Among them, the liquid collecting box 41 is used to collect the coolant for cooling the milling cutter 25 and the gravure cylinder 5; the liquid storage box 42 is used to collect and store the coolant collected by the liquid collecting box 41; the filter element 43 is used to filter debris to prevent the debris from entering the liquid storage box 42; the chip removal brushes 45 are used to remove the debris on the surface of the gravure cylinder 5; the flow pusher 46 is used to drive the coolant collected in the liquid collecting box 41 to flow, facilitating the concentration of debris.

[0043] The liquid collecting box 41 is integrally in a cuboid structure, its length direction is parallel to the length direction of the machine body 1, and its width direction is parallel to the width direction of the machine body 1; the liquid collecting box 41 is movably installed on the machine body 1 in the vertical direction, and it has a liquid collecting space 411 with an upward opening. During the process of the spray head 27 spraying the coolant, the liquid collecting box 41 can collect the coolant below the gravure cylinder 5.

[0044] Refer to Figure 3 and Figure 4, there is a linkage relationship between the movement of the liquid collection box 41 relative to the body 1 and the movement of the movable seat 31 relative to the body 1. When the movable seat 31 moves upward to the limit position, the liquid collection box 41 will move downward to the limit position; and when the movable seat 31 moves downward to the limit position, the liquid collection box 41 will move upward to the limit position. In this embodiment, it is preferably that the liquid collection box 41 and the two movable seats 31 both achieve the linkage relationship of synchronous reverse movement through the meshing of a gear and a rack; since the gear-rack structure with the above functions is a common prior art, it will not be elaborated here, and it is omitted in the drawings.

[0045] Furthermore, it is preferably that a plurality of elastic members 6 are further installed between the liquid collection box 41 and the body 1. The two ends of the elastic member 6 are respectively fixedly connected to the liquid collection box 41 and the body 1, and it is used to drive the liquid collection box 41 to move downward to the limit position and maintain it. In this embodiment, it is preferably that the elastic member 6 is a tension spring.

[0046] When the gravure cylinder 5 is not installed and positioned on the positioning device 3, at this time, the liquid collection box 41 will move downward to the limit position and maintain it under the action of the plurality of elastic members 6, and at the same time drive the two movable seats 31 to move upward to the limit position and maintain it. At this time, there is a certain distance between the fixture 32 on the movable seat 31 and the liquid collection box 41, which is convenient for the subsequent installation and positioning of the gravure cylinder 5 on the positioning device 3; When milling is performed after the gravure cylinder 5 is installed and positioned on the positioning device 3, at this time, the gravity of the gravure cylinder 5 will drive the two movable seats 31 to move downward to the limit position and maintain it, and at the same time drive the liquid collection box 41 to move upward to the limit position and maintain it after overcoming the acting force of the plurality of elastic members 6. At this time, the bottom of the printing part of the gravure cylinder 5 will be located in the liquid collection space 411, and during the process of the liquid collection box 41 collecting the coolant, the two movable seats 31 and the liquid collection box 41 itself will all maintain the current position state unchanged.

[0047] One end of the liquid collection box 41 in the length direction is provided with a liquid discharge port 412 for discharging the coolant at its bottom, and the inner wall of the bottom of the liquid collection space 411 is inclined downward towards the direction close to the liquid discharge port 412, which is convenient for the coolant in the liquid collection space 411 to flow towards the direction close to the liquid discharge port 412; a plurality of liquid discharge holes 413 for discharging the coolant are provided on both sides of the liquid collection box 41 in the width direction. The plurality of liquid discharge holes 413 on the same side are equidistantly distributed along the length direction of the liquid collection box 41, and the plurality of liquid discharge holes 413 on both sides are all located on the same horizontal plane.

[0048] The liquid storage box 42 is integrally in a cuboid structure. It is fixedly installed on the machine body 1 and is located below the liquid collection box 41. Its length direction is parallel to the length direction of the machine body 1, and its width direction is parallel to the width direction of the machine body 1. The liquid storage box 42 has a liquid storage space 421 with an upward opening. When the coolant in the liquid collection space 411 is discharged from the liquid discharge port 412 and the liquid discharge holes 413, the liquid storage space 421 can collect the discharged coolant. At the same time, the coolant stored in the liquid storage space 421 is used for spraying by the spray head 27. In this embodiment, since the method of using the coolant stored in the liquid storage box 42 by the spray head 27 is a common prior art, it will not be elaborated here, and it is omitted in the drawings.

[0049] The filter element 43 is installed on the liquid storage box 42 and is located above the liquid storage box 42. It is provided with a plurality of holes for the coolant to pass through and capable of intercepting debris, for filtering debris. The filter element 43 is integrally in an arc-shaped plate structure. A chip collection groove 431 for the accumulation of debris is formed on the side where the arc opening is located. One end of the arc track of the filter element 43 is rotatably connected to the liquid storage box 42, and the rotation axis is perpendicular to its own arc track and parallel to the width direction of the liquid storage box 42. In this embodiment, preferably, the liquid storage box 42 has a frame body, and the filter element 43 is installed on the frame body.

[0050] There are limitations during the rotation of the filter element 43 relative to the liquid storage box 42. When the filter element 43 rotates towards the liquid storage box 42 to the limit position, if the liquid collection box 41 moves upward to the limit position at this time, the filter element 43 can seal the liquid discharge port 412, so that the coolant discharged through the liquid discharge port 412 needs to pass through the filter element 43 for filtration before entering the liquid storage space 421 for storage, and the debris intercepted by the filter element 43 will accumulate in the chip collection groove 431. When the filter element 43 rotates away from the liquid storage box 42 to the limit position, if the liquid collection box 41 moves downward to the limit position at this time, the debris accumulated in the chip collection groove 431 can move along the filter element 43 towards the side of the liquid collection box 41 close to the liquid discharge port 412 in the length direction, facilitating the staff to transfer the debris for unified treatment.

[0051] Refer to Figure 2 and Figure 3, during the milling process of the gravure printing plate cylinder 5, when the liquid collecting box 41 collects the coolant, the debris on the surface of the gravure printing plate cylinder 5 will also be washed into the liquid collecting space 411 by the coolant and flow with the coolant towards the direction close to the liquid discharge port 412, and then the debris will be concentrated in the chip collecting groove 431; when the debris in the chip collecting groove 431 reaches a certain amount, the debris will block the filter element 43, resulting in the speed of the coolant discharged through the liquid discharge port 412 being less than the speed of the liquid collecting box 41 collecting the coolant or even causing the coolant to be unable to be discharged through the liquid discharge port 412; at this time, the liquid level of the coolant collected in the liquid collecting space 411 will rise until the coolant can be discharged through the liquid discharge holes 413 on both sides; and at this time, the bottom of the gravure printing plate cylinder 5 can be immersed in the coolant, which not only makes the cooling effect of the coolant on the gravure printing plate cylinder 5 more uniform, but also facilitates the debris on the surface of the gravure printing plate cylinder 5 to enter the liquid collecting space 411 after the gravure printing plate cylinder 5 rotates.

[0052] Refer to Figure 3 and Figure 4 , the chip collecting box 44 is fixedly installed on one side in the length direction of the liquid collecting box 41 and adjacent to the liquid discharge port 412, and it has a chip collecting space 441 with an upward opening; when the filter element 43 rotates towards the direction away from the liquid storage box 42 to the limit position and the liquid collecting box 41 moves downward to the limit position, the debris accumulated in the chip collecting groove 431 can move along the filter element 43 and enter the chip collecting space 441 for collection, which is convenient for the staff to uniformly process the debris later.

[0053] Furthermore, preferably, a driving part 414 for contacting one end of the filter element 43 close to its rotation axis is provided at a position on the top of the liquid collecting box 41 close to the chip collecting box 44.

[0054] When the liquid collecting box 41 moves upward to the limit position, at this time, the filter element 43 will maintain the position state of closing the liquid discharge port 412 under its own gravity; then, during the process of the liquid collecting box 41 moving downward to the limit position, the driving part 414 will contact the filter element 43 and drive the filter element 43 to rotate towards the direction away from the liquid storage box 42 to the limit position, facilitating the debris in the chip collecting groove 431 to move into the chip collecting space 441 for collection; and, since the liquid collecting box 41 is affected by the acting force of a plurality of elastic members 6 during the process of moving downward, the liquid collecting box 41 will vibrate to a certain extent after moving downward to the limit position, so that the filter element 43 will also vibrate to a certain extent after rotating towards the direction away from the liquid storage box 42 to the limit position, thereby making it more convenient for the debris in the chip collecting groove 431 to leave the filter element 43.

[0055] Refer to Figure 2 and Figure 4, the chip removal brush 45 is integrally in a cylindrical structure. It is installed in the liquid collection space 411, and both ends in the axial direction thereof are rotatably connected to the two inner walls in the length direction of the liquid collection space 411 respectively; the rotation axis of the chip removal brush 45 coincides with its own axis and its position relative to the liquid collection box 41 is higher than the position of the liquid discharge hole 413. A plurality of soft bristles are evenly distributed on its outer side. After the gravure printing plate cylinder 5 is installed on the positioning device 3, the outer sides of the chip removal brushes 45 are all in contact with the surface of the gravure printing plate cylinder 5. In this embodiment, preferably, the chip removal device 4 includes two chip removal brushes 45 in total, and the two chip removal brushes 45 are respectively close to both sides in the width direction of the liquid collection space 411 and are symmetrically distributed relative to the liquid collection box 41.

[0056] During the milling process of the gravure printing plate cylinder 5, when the gravure printing plate cylinder 5 rotates, the chip removal brush 45 can remove chips from the surface of the gravure printing plate cylinder 5, facilitating the chips to leave the gravure printing plate cylinder 5 and fall into the coolant collected in the liquid collection space 411.

[0057] Furthermore, preferably, when the coolant collected in the liquid collection space 411 can be discharged through the liquid discharge hole 413, the bottom of the chip removal brush 45 will be immersed in the coolant collected in the liquid collection space 411.

[0058] At this time, when the gravure printing plate cylinder 5 rotates during the milling process, the frictional force between the gravure printing plate cylinder 5 and the chip removal brush 45 can drive the chip removal brush 45 to rotate relative to the liquid collection box 41. Thus, on the one hand, the bristles on the chip removal brush 45 can remove chips from the surface of the gravure printing plate cylinder 5 in a state of being stained with coolant, so as to improve the chip removal effect of the chip removal brush 45 on the surface of the gravure printing plate cylinder 5; on the other hand, it can facilitate the chips removed by the chip removal brush 45 to contact the coolant in the liquid collection space 411, so that the chips can enter the coolant. At the same time, during the process of the chip removal brush 45 rotating with the rotation of the gravure printing plate cylinder 5, it can stir the coolant collected in the liquid collection space 411, thereby effectively improving the flushing effect of the coolant on the bottom surface of the gravure printing plate cylinder 5.

[0059] The flow pusher 46 is installed at a position close to the bottom in the liquid collection space 411 and is rotatably connected to the inner wall on the side away from the liquid discharge port 412 in the length direction of the liquid collection space 411, and the rotation axis of the flow pusher 46 is parallel to the rotation axis of the chip removal brush 45.

[0060] Refer to Figure 2 and Figure 3, a linkage is formed between the rotation of the two chip removal brushes 45 relative to the liquid collection box 41 and the rotation of the flow pusher 46 relative to the liquid collection box 41. During the process of the chip removal brush 45 rotating relative to the liquid collection box 41 driven by the gravure cylinder 5, the chip removal brush 45 can drive the flow pusher 46 to rotate relative to the liquid collection box 41, and the rotation of the flow pusher 46 can drive the coolant in the liquid collection space 411 to flow in the direction close to the liquid discharge port 412, so as to facilitate the chips to move in the direction close to the filter element 43 along with the coolant. In this embodiment, preferably, the two chip removal brushes 45 and the flow pusher 46 are linked through a synchronous pulley structure, and preferably, during the process of the fourth driving member 33 driving the gravure cylinder 5 to rotate, the gravure cylinder 5 rotates in one direction, so that the above effects can be effectively achieved after the flow pusher 46 rotates accordingly; since the synchronous pulley structure is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0061] The implementation principle of a milling tool for a gravure cylinder in an embodiment of the present application is as follows: After the gravure cylinder 5 is installed and positioned on the positioning device 3, the milling device 2 and the positioning device 3 can be controlled to mill the gravure cylinder 5; during the process of milling the gravure cylinder 5, the coolant sprayed by the spray head 27 can effectively cool the milling cutter 25 and the position on the top of the gravure cylinder 5 being milled, and at the same time, it can wash away the chips generated by milling so that they enter the liquid collection space 411 together with the coolant for collection; The chips entering the liquid collection space 411 can move in the direction close to the liquid discharge port 412 along with the coolant until they are filtered by the filter element 43 and concentrated in the chip collection groove 431. The coolant discharged from the liquid discharge port 412 can enter the liquid storage space 421 for collection and storage, which is convenient for the spray head 27 to spray and use; when a certain amount of chips are concentrated in the chip collection groove 431, the filter element 43 will be blocked by the chips, causing the liquid level of the coolant collected in the liquid collection space 411 to rise, so that the bottom of the gravure cylinder 5 is immersed in the coolant. At this time, the excess coolant can be discharged through a plurality of liquid discharge holes 413 and fall into the liquid storage space 421 for collection; During the milling process, when the fourth driving member 33 drives the gravure cylinder 5 to rotate, the plurality of chip removal brushes 45 can remove chips from the surface of the gravure cylinder 5; at the same time, the plurality of chip removal brushes 45 can rotate accordingly and drive the flow pusher 46 to rotate, driving the coolant collected in the liquid collection space 411 to flow in the direction close to the liquid discharge port 412 and driving the chips to move in the direction close to the filter element 43; After the milling process of the gravure cylinder 5 is completed, it is removed. At this time, the liquid collecting box 41 will move downward to the limit position under its own gravity and the action of multiple elastic members 6, and at the same time drive the two movable seats 31 to move upward to the limit position, facilitating the installation and positioning of the next gravure cylinder 5 on the positioning device 3. At the same time, the filter member 43 can rotate as the liquid collecting box 41 moves downward, enabling the debris in the chip collecting groove 431 to move into the chip collecting box 44 for collection, which is convenient for the subsequent unified handling by the staff.

[0062] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
