Description

Technical Field

[0001] This application relates to the technical field of milling devices, and particularly to a gravure cylinder milling device. Background Art

[0002] The gravure cylinder is the core component of gravure printing. Through the groove structure on its surface, the ink is accurately transferred to achieve high-precision pattern printing. The production of gravure cylinders mainly includes multiple processes such as substrate treatment, copper plating, engraving, and chrome plating, and finally forms a printing tool with high printing resistance and stability.

[0003] Among them, the engraving process is mainly to process grooves on the surface of the cylinder to form the required pattern. Generally, laser engraving, electronic engraving, or milling engraving methods are used. In some large-format gravure cylinders, the milling method is used to engrave the main contour, and then it is polished and flattened through finishing to improve the accuracy.

[0004] During milling machine processing, a coolant nozzle is generally set at the tool head. The coolant nozzle moves with the tool head and flushes and cools the tool head. Part of the chips generated during processing fly out under the centrifugal force of the tool head, and part adheres to the surface of the cylinder along with the coolant flow. The remaining built-up edge chips will affect the subsequent processing quality. At the same time, if the chips splashed on the processing table are not cleaned up, it will also affect production.

[0030] Referring to Figure 1 and Figure 2 , in an embodiment of this application, it further includes a chip removal mechanism 4, a chip collection mechanism 5 and a chip discharging mechanism 6. Among them, the chip removal mechanism 4 is used to remove the chips on the surface of the printing plate roller, the chip collection mechanism 5 collects the chips generated during the milling process, and the chip discharging mechanism 6 squeezes and discharges the chips. Each mechanism cooperates with each other, can timely clean the chips on the surface of the printing plate roller, and at the same time timely collect and clean the chips generated during the milling process, avoiding the chips from affecting the operation of the equipment.

[0031] Referring to Figure 1 and Figure 2, in the embodiment of the present application, specifically, the chip collecting mechanism 5 includes a chip baffle 51 and a chip collecting box 52 arranged on the machine table 1. The chip baffle 51 is an arc-shaped plate, which is respectively arranged on both sides of the positioning mechanism 2, so as to form a nearly semi-circular structure between the two layers of the plate roller, and can effectively block the flying chips during the milling process. The chip collecting box 52 is located between the two chip baffles 51 and is connected to the lower ends of the two chip baffles 51, with an upward opening. The chips sputtered on the chip baffle 51 will slowly move downward under the action of gravity and coolant, and enter the chip collecting box 52 for collection.

[0032] Referring to Figure 1 and Figure 2 , in the embodiment of the present application, the chip collecting box 52 is embedded in the machine table 1, and its lower part extends downward through the tabletop of the machine table 1; a plurality of filter holes 521 are uniformly arranged on one side plate of the chip collecting box 52 for filtering the coolant, so that the coolant can flow out of the chip collecting box 52. A switch door 526 capable of opening and closing to discharge chips is provided at the bottom of the chip collecting box 52. The chip collecting mechanism 5 further includes a first driving member 53 for driving the opening and closing of the switch door 526, and a chip collecting frame 54 for collecting chips. Among them, the first driving member 53 is arranged on the machine table 1, and the chip collecting frame 54 is arranged below the chip collecting box 52. When the first driving member 53 opens the switch door 526, the chips extruded by the chip discharging mechanism 6 can fall downward into the chip collecting frame 54 under the action of gravity.

[0033] Referring to Figure 2 and Figure 3 , specifically, a mounting seat 11 is fixed on the lower surface of the machine table 1, and the mounting seat 11 is respectively arranged at both ends of the switch door 526. The switch door 526 is an overall rectangular plate, and rotating shafts are fixed on the end faces of both ends thereof, and it is rotatably connected to the mounting seat 11 through the rotating shafts. The first driving member 53 is preferably a first air cylinder 531. The first air cylinder 531 is hinged to the machine table 1 by means of setting a support seat, etc. The upper surface of the switch door 526 can also be hinged to the end of the telescopic shaft of the first air cylinder 531 by means of setting a support seat. When the telescopic shaft of the first air cylinder 531 extends, it can drive the switch door 526 to rotate to seal the chip collecting box 52, and when it contracts, it can drive the switch door 526 to open.

[0034] Referring to Figure 1 and Figure 2, the chip removal mechanism 4 includes a chip removal brush roller 41 rotatably arranged on the machine table 1 and a power source 42 for driving the rotation of the chip removal brush roller 41. The chip removal brush roller 41 is arranged between the plate roller and the chip collection box 52, and the chip removal brush roller 41 extends along the length direction of the plate roller; bristles are circumferentially arranged on the surface of the chip removal brush roller 41. When the plate roller is placed on the positioning mechanism 2, the tails of the bristles on the chip removal brush roller 41 abut against the side wall of the plate roller and can extend into the grooves on the surface of the plate roller, effectively removing the debris on the surface and in the grooves of the plate roller. Optionally, the bristles on the chip removal brush roller 41 can be made of nylon bristles, and their soft texture can cause less damage to the surface of the plate roller. The power source 42 can be a motor, which drives the rotation of the chip removal brush roller 41 through a belt or a chain. The two ends of the chip removal brush roller 41 can be fixed by setting supports on the machine table 1, or can also be fixed on the positioning mechanism 2.

[0035] Referring to Figure 1 and Figure 2 , in an alternative embodiment, the gravure plate roller milling device further includes a flushing mechanism 7; the flushing mechanism 7 includes a flushing pipe 71, flushing nozzles 72, a water guide plate 73, a water collection tank 74 and a circulation pipe 75. The water guide plate 73 is arranged on the machine table 1 and is inclined downward below the side plate of the chip collection box 52 where the filter holes 521 are opened. After the coolant flows out from the filter holes 521 on the side wall of the chip collection box 52, it can flow into the water collection tank 74 along the water guide plate 73. The flushing pipe 71 is arranged inside the baffle plate 51 and extends along the length direction of the plate roller. A plurality of flushing nozzles 72 are arranged at intervals along the flushing pipe 71. The flushing nozzles 72 can preferably be fan-shaped nozzles, so as to improve the flushing effect on the side wall of the plate roller. Preferably, when the plate roller rotates, it first passes through the chip removal brush roller 41 for cleaning and then rotates to the position of the flushing nozzles 72, so as to further flush and clean the plate roller and improve the cleaning effect on the plate roller. The circulation pipe 75 is used to send the coolant in the water collection tank 74 to the flushing pipe 71, and a pump or other equipment can be used to pump the coolant between it and the water collection tank 74.

[0036] The water collection tank 74 is mainly used to store the used coolant and provide coolant for the flushing pipe 71, so as to reuse the coolant and improve the utilization rate of the coolant; a liquid level sensor can be arranged inside it, and a coolant inlet pipe can also be externally connected; when the liquid level is lower than a certain value, the coolant can be automatically replenished through the inlet pipe to ensure the normal use of the flushing pipe 71.

[0037] Referring to Figure 2 and Figure 4, in the embodiment of the present application, the chip removal mechanism 6 includes an extrusion seat 61 and a driving component 62 for driving the extrusion seat 61 to move up and down. The extrusion seat 61 extends along the length direction of the plate roller. When the extrusion seat 61 moves downward into the chip collection box 52, the side wall on the circumference of the extrusion seat 61 abuts against the inner side wall of the chip collection box 52, which can extrude the chips in the chip collection box 52 to form blocks, facilitating the discharge; at the same time, it can reduce the volume of the chips, facilitating the collection of the chips; further, when the extrusion seat 61 slides into the chip collection box 52 to extrude the chips, the coolant between the chips can be extruded and discharged from the filter holes 521 on one side, and the abutment of the extrusion seat 61 against the inner side wall of the chip collection box 52 can isolate the space below the extrusion seat 61 from the above. When the extrusion is completed, the coolant in the space below the extrusion seat 61 can be discharged as much as possible, improving the recovery rate of the coolant. At this time, the switch door 526 is opened by the first cylinder 531, and the extruded chip blocks can be discharged from the lower end outlet of the chip collection box 52.

[0038] Refer to Figure 3 and Figure 4 , in an optional embodiment, the upper surface of the extrusion seat 61 protrudes upward as an arc surface, and a rectangular rib 611 is arranged on the upper surface of the extrusion seat 61. The rectangular rib 611 extends along the length direction of the extrusion seat 61, and it can be made by a one-time molding method; when the extrusion seat 61 moves to the upper end, the tail of the brush hair end on the chip removal brush 41 abuts against the rectangular rib 611, so as to clean the brush hair on the chip removal brush 41 and prevent too much chips from adhering to the brush hair, affecting the chip removal effect.

[0039] Refer to Figure 2 and Figure 4 , further optionally, the upper and lower surfaces of the extrusion seat 61 are symmetrically arranged. When the driving component 62 drives the extrusion seat 61 to move up and down, the extrusion seat 61 can be turned up and down once in the middle. Every time the extrusion seat 61 presses the chips downward, the chips accumulated on the upper surface of the extrusion seat 61 can fall downward during the turning process and be compressed and discharged along with the extrusion action.

[0040] Refer to Figure 4 and Figure 5The driving assembly 62 includes a fixed seat 621, a sliding seat 622, a second cylinder 623, a connecting seat 624, a positioning column 625, a flip control block 626 and a gear 627. The fixed plate is arranged on the machine 1 along the vertical direction and can be fixed by bolts or welding; the sliding seat 622 is arranged on the fixed seat 621 to slide up and down, and the sliding seat 622 and the fixed seat 621 can be guided by setting a guide rail. In this embodiment, the sliding seat 622 is guided by opening a groove on the fixed seat 621 for the sliding seat 622 to slide up and down; the second cylinder 623 is fixed on the machine 1, and the telescopic axis of the second cylinder 623 is arranged vertically upward and the end of the telescopic axis is connected to the sliding seat 622; the driving shaft 616 is fixed on the side walls at both ends of the extrusion seat 61, and the driving shaft 616 is rotatably connected to the sliding seat 622, and it can be rotatably connected to the sliding seat 622 by bearings or the like; starting the second cylinder 623 can control the sliding seat 622 to move up and down, thereby controlling the extrusion seat 61 to move up and down.

[0041] Furthermore, the end of the driving shaft 616 passes through the fixed seat 621 and is connected to the connecting seat 624. The connecting seat 624 is a rectangular block structure. The positioning column 625 is fixed on the connecting seat 624. It and the driving shaft 616 can be connected to the two ends of the connecting seat 624 respectively. The positioning column 625 extends toward the extrusion seat 61. The flip control block 626 is arranged on the fixed seat 621. The flip control block 626 is provided with teeth on the side facing the driving shaft 616. The teeth are arranged at intervals along the vertical direction. The gear 627 is coaxially sleeved on the driving shaft 616. When the driving shaft 616 moves up and down, the gear 627 can move with it and pass through the flip control block 626 during the movement, and mesh with the teeth on the side wall of the flip control block 626.

[0042] The fixing seat 621 is provided with an upper positioning hole 6211 and a lower positioning hole 6212 on the upper and lower sides of the flip control block 626 for the positioning column 625 to slide up and down. The upper positioning hole 6211 and the lower positioning hole 6212 are both oriented in the vertical direction. A corresponding space is provided on the fixing seat 621 for the driving shaft 616 and the positioning column 625 to move. When the driving shaft 616 moves downward until the gear 627 meshes with the teeth on the flip control block 626, the positioning column 625 moves downward out of the upper positioning hole 6211; when the gear 627 passes through the flip control block 626, the gear 627 drives the driving shaft 616 to rotate half a circle; when the gear 627 is separated from the flip control block 626, the positioning column 625 moves downward into the lower positioning hole 6212.

[0043] When the second cylinder 623 controls the sliding seat 622 to move downward, the positioning post 625 moves downward within the upper positioning hole 6211, playing a role in guiding and limiting. At this time, the extrusion seat 61 and the drive shaft 616 move downward a small distance accordingly; when the second cylinder 623 controls the sliding seat 622 to continue moving downward, when the drive shaft 616 passes through the position of the flipping control block 626, the positioning post 625 disengages from the upper positioning hole 6211, the gear 627 meshes with the tooth teeth, the drive shaft 616 rotates, driving the extrusion seat 61 to flip 180 degrees accordingly. At the same time, the connecting seat 624 and the positioning post 625 also rotate 180 degrees, and the positioning post 625 rotates to a position below the drive shaft 616; when the second cylinder 623 controls the sliding seat 622 to continue moving downward, the positioning post 625 enters the lower positioning hole 6212, playing a guiding role again, and the flipped extrusion seat 61 moves downward a distance synchronously.

[0044] Preferably, in order to achieve automatic control, a sensor can be embedded in the chip collection box 52. When it senses that the chips have accumulated to a predetermined height, it automatically controls the second cylinder 623 and the first cylinder 531 to be turned on in sequence to complete the processes of automatic extrusion and automatic chip removal.

[0045] Refer to Figure 1 and Figure 6 As shown in FIGS. and, the drive assemblies 62 are respectively arranged at both ends of the chip collection box 52. Long slots 522 for the drive shaft 616 to slide up and down are formed on the side plates at both ends of the chip collection box 52. A water baffle 523 is further arranged on the side plates at both ends of the chip collection box 52, and a first spring 524 for driving the water baffle 523 to move upward to block the long slot 522 is provided. Meanwhile, the baffle is arranged to slide up and down, and its two ends are inserted into the side wall of the long slot 522, so as to form a shield at the long slot 522. When the extrusion seat 61 moves downward and the drive shaft 616 slides into the long slot 522, the baffle is pressed to slide downward. When the drive shaft 616 moves upward, the baffle moves upward under the action of the first spring 524, preventing the coolant from splashing out of the chip collection box 52 from the long slot 522 during the chip collection process.

[0046] Furthermore, the water baffle 523 includes an inner side plate and an outer side plate that are parallel to each other, and a top plate connected to the upper ends of the inner side plate and the outer side plate, so that the whole water baffle 523 forms an inverted "concave" structure; corresponding slots 525 for the inner side plate and the outer side plate to slide up and down are formed on the side plate of the chip collection box 52. The first spring 524 is arranged between the lower surface of the top plate and the side plate. When the water baffle 523 slides upward to abut against the upper side wall of the chute, the first spring 524 is in a compressed state, so that the first spring 524 can always drive the water baffle 523 to slide upward.

[0047] Refer to Figure 4 and Figure 7, in an optional embodiment, mounting grooves 612 are formed along the length direction on two side walls of the extrusion seat 61 that are parallel to each other. A cleaning brush 613 is arranged in the mounting groove 612. The cleaning brush 613 is strip-shaped, and the end of the bristles of the cleaning brush 613 extends out of the mounting groove 612. When the extrusion seat 61 enters the chip collection box 52, the bristles of the cleaning brush 613 can brush the upper part of the chip collection box 52 to prevent debris from adhering to the inner wall of the upper end of the chip collection box 52.

[0048] Further optionally, the cleaning brush 613 is slidably arranged in the mounting groove 612, and second springs 614 are uniformly arranged between the bottom wall of the cleaning brush 613 and the mounting groove 612 along the length direction of the cleaning brush 613. At the same time, a limiting strip 615 is fixed on the side wall of the cleaning brush 613, and a limiting groove for the limiting strip 615 to slide is formed on the side wall of the mounting groove 612. When the limiting strip 615 abuts against the outer side wall of the limiting groove when the cleaning brush 613 slides away from the second spring 614, the second spring 614 is still in a compressed state.

[0049] The setting of the water baffle 523 can prevent the coolant from splashing to the outside from the long grooves 522 at both ends of the chip collection box 52, and the function of the first spring 524 ensures that the water baffle 523 can move upward in time to block the long grooves 522.

[0050] The implementation principle of an intaglio printing plate roller milling device in an embodiment of the present application is as follows: The positioning mechanism 2 first stably positions the printing plate roller on the machine table 1, and the milling mechanism 3 mills the printing plate roller. During the processing, the chip removal roller brush 41 of the chip removal mechanism 4 rotates, and its bristles contact the surface of the printing plate roller to remove the debris on the surface and in the grooves of the printing plate roller. The area of the printing plate roller cleaned by the chip removal roller brush 41 continues to rotate to the position where the flushing pipe 71 is located and is further cleaned by the coolant ejected from the flushing nozzle 72. At the same time, the debris cleaned by the chip removal roller brush 41 and the debris splashed during processing are blocked by the baffle 51, and these debris and coolant fall into the chip collection box 52 of the chip collection mechanism 5 under the action of gravity. Among them, the coolant can be discharged from the chip collection box 52 along the filter holes 521 and fall into the water collection tank 74 along the water guide plate 73 for collection. The collected coolant is sent to the flushing pipe 71 through the circulation pipe 75 for reuse.

[0051] During the rotation of the chip removal roller brush 41, the debris on its bristles is scraped and cleaned by the rectangular protrusions 611 on the extrusion seat 61. When the debris in the chip collection box 52 accumulates to a certain extent, the driving component 62 of the chip discharging mechanism 6 drives the extrusion seat 61 to move downward, and it flips once during the downward movement, and then squeezes the debris in the chip collection box 52 to form a debris block. Finally, the first driving member 53 drives the switch door 526 to open, and the debris block is discharged from the lower end outlet of the chip collection box 52 into the chip collection frame 54.

[0052] This method solves the problem that debris adheres to the surface of the gravure plate cylinder during the milling process, which affects the processing quality; at the same time, the generated debris is effectively collected, improving the quality and efficiency of the gravure plate cylinder milling process.

[0053] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
