Description

Technical Field

[0001] This invention relates to the field of gravure roller engraving technology, specifically an intelligent engraving device for gravure printing rollers. Background Technology

[0002] Gravure printing is the most common printing process. In gravure printing, the printing area is lower than the blank area on the printing roller. The degree of depression in the printing area varies depending on the depth of the image. During printing, the printing roller rolls through the ink to coat it with ink. A doctor blade scrapes away the ink from the blank areas on the printing roller, so that the ink is only retained in the recessed printing area. An impression roller is set above the printing roller. The substrate passes between the printing roller and the impression roller and is squeezed by the impression roller to print the corresponding pattern. Gravure printing rollers are usually metal rollers.

[0003] The pattern on the printing plate is formed by laser engraving. Traditional laser plate making machines engrave each plate individually, but the efficiency of removing the material from the surface of the impression roller is relatively low when engraving deep recessed graphics. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent engraving device for gravure printing rollers to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The intelligent engraving device for gravure printing rollers includes a worktable, on which a transverse slide rail is mounted, a longitudinal slide rail is slidably mounted on the transverse slide rail, a sliding table is slidably mounted on the longitudinal slide rail, a compensating rod is rotatably mounted on the sliding table, a rough engraving drill bit and a laser head are mounted on the other end of the compensating rod, two support platforms are symmetrically mounted on the worktable, each support platform is rotatably mounted with an mounting shaft, each mounting shaft is mounted with a clamp, and a turbine is mounted on one of the mounting shafts. The worktable is located near the turbine. A rotary motor is installed on one side, and a worm gear is installed at the output end of the rotary motor. The worm gear meshes with a turbine. When it is necessary to engrave the gravure roller, the roller is clamped with a fixture. The longitudinal and transverse slide rails drive the sliding table to move in the XY plane. The coordinating rod drives the roughing drill bit and laser head to move and rotate in the Z direction. The rotary motor is started, and the fixture is slowly rotated through the meshing of the turbine and worm gear. This allows the roughing drill bit and laser head to engrave the gravure roller from multiple angles. After the roughing drill bit performs rough processing to carve out the general outline, the laser head is used to carve the details, achieving a rapid engraving effect.

[0006] As a preferred technical solution, an electric slide rail is installed on the side of the worktable away from the transverse slide rail. A lifting platform is mounted on the electric slide rail, and a liquid supply tank is mounted on the lifting platform. A telescopic rod is rotatably mounted on the liquid supply tank, and a nozzle is vertically mounted on the other end of the telescopic rod. The telescopic rod is electrically connected to the roughing drill bit. When the roughing drill bit processes the gravure roller, the position of the nozzle is adjusted by the electric slide rail and the lifting platform, and the angle of the coolant output from the nozzle is adjusted by rotating the telescopic rod. This reduces the temperature at the contact point between the roughing drill bit and the gravure roller during processing and prevents processing chips from spreading into the air under impact.

[0007] As a preferred technical solution, the workbench has a chamber, and the chamber is equipped with a multi-stage filtration assembly and a metal chip cleaning assembly. The multi-stage filtration assembly filters and recycles the coolant, and the metal chip cleaning assembly automatically cleans up the metal chips generated during engraving.

[0008] As a preferred technical solution, the multi-stage filtration assembly includes a filter grid, a storage box, a circular hole, a magnetic roller, a large pulley, a sprocket, a drive motor, a rotating shaft, a small pulley, a first belt, a filter box, a filter plate, a first filter chamber, a second filter chamber, a third filter chamber, an input port, a circulation pump, and a mounting box.

[0009] The workbench has a filter opening, and a filter grid is installed inside the filter opening. A barrier is installed around the filter opening. A storage box is installed inside the chamber, and multiple magnetic rollers are rotatably mounted inside the storage box. A sprocket is mounted on the same rotating end of each of the magnetic rollers, and a chain is fitted onto each sprocket. A drive motor is installed inside the chamber, and a rotating shaft is installed at the output end of the drive motor. A small pulley is mounted on the other end of the rotating shaft. A large pulley is mounted on the rotating end of the magnetic roller near the small pulley. A first belt is fitted between the large pulley and the small pulley. A circular hole is opened at the bottom of the storage box, and a mounting box is installed at the bottom of the circular hole. A filter box is installed inside the chamber, and three filter plates are installed inside the filter box, dividing the filter box into a first filter chamber, a second filter chamber, and a third filter chamber. The first filter chamber has an input hole at the top, which is connected to the output end of the mounting box via a pipe. A circulation pump is installed in the chamber, and the input end of the circulation pump is connected to the output end of the filter box via a pipe. The output end of the circulation pump is also connected to the input end of the liquid supply tank via a pipe. When the engraving roller is in operation, the drive motor is started to drive multiple magnetic rollers to rotate slowly. When the coolant carries iron filings down, the larger metal filings are first filtered through the filter grid and then flow into the storage box. Before the cutting fluid falls to the bottom of the storage box, the magnetic rollers adsorb the metal filings that can be adsorbed. The non-adsorbable metal filings and cutting fluid flow out through the round hole. After flowing into the filter box, the cutting fluid is filtered through the first, second, and third filter chambers and then drawn out by the circulation pump. It is then fed into the liquid supply tank, thus completing the multi-stage filtration and recycling of the cutting fluid.

[0010] As a preferred technical solution, the three filter plates have different mesh counts.

[0011] As a preferred technical solution, the multi-stage filtration assembly further includes a track, an electric sliding block, a connecting rod, a slide bar, and a plug;

[0012] The installation box contains two tracks, each with a sliding electric sliding block. Each sliding block is hinged with a connecting rod, and each connecting rod is hinged with a sliding rod. The sliding rod passes through a circular hole, and a plug is installed at the top of the sliding rod. When the storage box needs cleaning, the electric sliding block drives the connecting rod to slide away from each other, causing the sliding rod to move down and thus sealing the circular hole with the plug, preventing a large amount of metal debris from entering the filter box.

[0013] As a preferred technical solution, the metal scrap cleaning assembly includes a reciprocating lead screw, a folding protective sleeve, a scraper, a pressure groove, a fitting groove, a collection groove, an output port, a cover plate, a sealing ring, a push rod, and a return spring.

[0014] A reciprocating screw is rotatably mounted inside the storage box, located below the magnetic rollers. A scraper is slidably mounted on the reciprocating screw, and the top of the scraper has multiple fitting grooves, each corresponding to a position of one of the magnetic rollers. An output port is located on the side of the storage box near the sprocket. A cover plate is hinged to the bottom of the storage box, and a sealing ring is mounted on the cover plate, engaging with the output port. A stop rod is mounted on the cover plate, passing through the output port. The end of the cover plate is flush with the storage box. The boxes are connected by a return spring. A folding protective sleeve is fitted on the reciprocating screw. The reciprocating screw rotates by a driving force. When the magnetic rollers and storage box need to be cleaned, the reciprocating screw is driven to rotate slowly. The rotation of the reciprocating screw drives the scraper to move, cleaning the metal debris adsorbed on the multiple magnetic rollers and the metal debris deposited at the bottom of the storage box. When the metal debris is scraped to the other end of the storage box, the scraper touches the stop rod and presses down, causing the sealing ring to disengage from the output port, thereby discharging the metal debris into the collection tank.

[0015] As a preferred technical solution, the metal scrap cleaning assembly further includes a driven pulley, a first drive wheel, a rotating support plate, a drive shaft, a second drive wheel, a ratchet, a driven shaft, a driven disc, a pawl, a reset push rod, an arc-shaped slide, a clamping rod, a gantry frame, a telescopic head, a drive pulley, and a second belt;

[0016] A driven pulley is mounted on the end of the reciprocating screw away from the sprocket. A rotating support plate and a gantry frame are mounted on the side of the chamber closest to the driven pulley. A driving shaft is rotatably mounted on the rotating support plate. A second drive wheel is mounted on the driving shaft. A first drive wheel is mounted on the rotating shaft. Drive belts are fitted onto the first and second drive wheels. A ratchet is mounted on the other end of the driving shaft. A driven shaft is rotatably mounted in the chamber, coaxial with the driving shaft. A driven disc is mounted on the end of the driven shaft closest to the ratchet. A pawl is rotatably mounted on the driven disc. An arc is formed on the driven disc. The slide rail has a shaped guide rail. A locking rod is installed at the other end of the pawl, and the end of the locking rod is engaged within the shaped guide rail. A reset push rod is installed on the driven disc, and the output end of the reset push rod contacts the pawl. A telescopic head is installed on the gantry frame, and the telescopic head is located directly above the ratchet. A drive pulley is installed at the end of the driven shaft away from the driven disc. A second belt is fitted between the drive pulley and the driven pulley. When the magnetic roller and storage box need cleaning, the telescopic head retracts, and the reset push rod pushes the pawl to contact the ratchet, causing the driven disc and ratchet to rotate synchronously. This drives the drive pulley on the driven shaft to rotate, providing driving force for the reciprocating screw.

[0017] As a preferred technical solution, the telescopic head is electrically connected to the electric sliding block, and the initial state of the telescopic head is that the pawl is pressed down so that the pawl does not contact the ratchet.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This application uses longitudinal and transverse slide rails to move the sliding table in the XY plane, and uses a compensating rod to move and rotate the roughing drill bit and laser head in the Z direction. The starting motor drives the fixture to rotate slowly through the meshing of the worm gear and turbine, so that the roughing drill bit and laser head can engrave the gravure roller at multiple angles, achieving a rapid engraving effect. The position of the nozzle is adjusted by the electric slide rail and lifting platform, and the angle of the coolant output by the nozzle is adjusted by the rotation of the telescopic rod, thereby reducing the temperature at the contact point between the roughing drill bit and the gravure roller during processing and preventing the processing chips from spreading in the air under the action of impact.

[0020] 2. This application uses a drive motor to slowly rotate multiple magnetic rollers. When the coolant carries iron filings down, the larger metal filings are first filtered through a filter grid before flowing into the storage box. Before the cutting fluid falls to the bottom of the storage box, the magnetic rollers attract the metal filings that can be attracted. The non-attractable metal filings and cutting fluid flow out through the round holes. After flowing into the filter box, the cutting fluid is filtered through the first, second and third filter chambers and then drawn out by the circulation pump. It is then fed into the supply tank, thus completing the multi-stage filtration and recycling of the cutting fluid.

[0021] 3. In this application, the telescopic head retracts, and the reset push rod pushes the pawl to contact the ratchet, thereby causing the driven disc and the ratchet to rotate synchronously. This drives the drive pulley on the driven shaft to rotate, providing driving force for the reciprocating screw. The reciprocating screw rotates slowly, driving the scraper to move and clean the metal debris adsorbed on the multiple magnetic rollers and the metal debris deposited at the bottom of the storage box. When the metal debris is scraped to the other end of the storage box, the scraper touches the stop rod and presses down, causing the sealing ring to disengage from the output port, thereby discharging the metal debris into the collection tank.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Figures 1-4 As shown, the present invention provides a technical solution for an intelligent engraving device for gravure printing rollers. This intelligent engraving device includes a worktable 1, on which a transverse slide rail 101 is mounted. A longitudinal slide rail 102 is slidably mounted on the transverse slide rail 101. A sliding table 103 is slidably mounted on the longitudinal slide rail 102. A compensating rod 104 is rotatably mounted on the sliding table 103. A roughing drill bit 105 and a laser head 106 are mounted at the other end of the compensating rod 104. Two support platforms 107 are symmetrically mounted on the worktable 1. Mounting shafts 109 are rotatably mounted on both support platforms 107. Clamps 108 are mounted on both mounting shafts 109. A turbine 110 is mounted on one mounting shaft 109. A fixture 108 is mounted on the side of the worktable 1 closest to the turbine 110. There is a rotary motor 117, and a worm gear 111 is installed at the output end of the rotary motor 117. The worm gear 111 meshes with the turbine 110. When it is necessary to engrave the gravure roller, the roller is clamped with the fixture 108. The longitudinal slide rail 102 and the transverse slide rail 101 drive the sliding table 103 to move in the XY plane. The compensating rod 104 drives the rough engraving drill bit 105 and the laser head 106 to move and rotate in the Z direction. The rotary motor 117 is started, and the fixture 108 is slowly rotated through the meshing of the turbine 110 and the worm gear 111. This allows the rough engraving drill bit 105 and the laser head 106 to engrave the gravure roller from multiple angles. After the rough engraving drill bit 105 performs rough processing to engrave the general outline, the laser head 106 engraves the details to achieve a rapid engraving effect.

[0037] An electric slide rail 112 is installed on the side of the worktable 1 away from the transverse slide rail 101. A lifting platform 113 is installed on the electric slide rail 112, and a liquid supply tank 114 is installed on the lifting platform 113. A telescopic rod 115 is rotatably installed on the liquid supply tank 114, and a nozzle 116 is vertically installed at the other end of the telescopic rod 115. The telescopic rod 115 is electrically connected to the roughing drill bit 105. When the roughing drill bit 105 processes the gravure roller, the position of the nozzle 116 is adjusted by the electric slide rail 112 and the lifting platform 113, and the angle of the coolant output by the nozzle 116 is adjusted by rotating the telescopic rod 115. This reduces the temperature at the contact point between the roughing drill bit 105 and the gravure roller during processing and prevents processing chips from spreading in the air under the action of impact.

[0038] The workbench 1 has a chamber 2, which is equipped with a multi-stage filtration assembly 5 and a chip cleaning assembly 6. The multi-stage filtration assembly 5 filters and recycles the coolant, and the chip cleaning assembly 6 automatically cleans up the chips generated during engraving.

[0039] like Figures 2-4 and Figures 6-7 As shown, the multi-stage filtration assembly 5 includes a filter grid 501, a storage box 502, a circular hole 5021, a magnetic roller 503, a large pulley 504, a sprocket 505, a drive motor 506, a rotating shaft 508, a small pulley 509, a first belt 511, a filter box 512, a filter plate 513, a first filter chamber 5131, a second filter chamber 5132, a third filter chamber 5133, an inlet 514, a circulation pump 515, and a mounting box 516.

[0040] The workbench 1 has a filter port 3, inside which a filter grid 501 is installed. A surrounding barrier 4 is installed around the filter port 3. A storage box 502 is installed inside the chamber 2. Multiple magnetic rollers 503 are rotatably mounted inside the storage box 502. A sprocket 505 is installed on the same rotating end of each magnetic roller 503, and a chain is fitted onto each sprocket 505. A drive motor 506 is installed inside the chamber 2. A rotating shaft 508 is installed at the output end of the drive motor 506, and a small pulley 509 is installed at the other end of the rotating shaft 508. A large pulley 504 is installed on the rotating end of the magnetic roller 503 near the small pulley 509. A first belt 511 is fitted between the large pulley 504 and the small pulley 509. A circular hole 5021 is opened at the bottom of the storage box 502, and a mounting box 516 is installed at the bottom of the circular hole 5021. A filter box 512 is installed in the chamber 2. Three filter plates 513 are installed in the filter box 512, which divides the filter box 512 into a first filter chamber 5131, a second filter chamber 5132, and a third filter chamber 5133. 33. An input hole 514 is provided at the top of the first filter chamber 5131. The input hole 514 is connected to the output end of the mounting box 516 through a pipe. A circulation pump 515 is installed in the chamber 2. The input end of the circulation pump 515 is connected to the output end of the filter box 512 through a pipe. The output end of the circulation pump 515 is connected to the input end of the liquid supply tank 114 through a pipe. When the engraving gravure roller is being engraved, the drive motor 506 is started to drive multiple magnetic rollers 503 to rotate slowly. When the coolant carries iron filings down, they first pass through the filter grid 501 to remove the iron filings. Large metal shavings are filtered and flow into the storage box 502. Before the cutting fluid falls to the bottom of the storage box 502, it passes through multiple magnetic rollers 503 to attract adsorbable metal shavings. Non-adsorbable metal shavings and cutting fluid flow out through the round hole 5021. After flowing into the filter box 512, it is filtered by the first filter chamber 5131, the second filter chamber 5132 and the third filter chamber 5133 and then sucked out by the circulation pump 515. It is then fed into the supply tank 114, thus completing the multi-stage filtration and recycling of the cutting fluid.

[0041] The three filter plates of 513 all have different mesh sizes.

[0042] The multi-stage filter assembly 5 also includes a track 5161, an electric sliding block 5162, a connecting rod 5163, a slide bar 5164, and a plug 5165;

[0043] Two tracks 5161 are installed inside the circular box 516, and electric sliding blocks 5162 are slidably mounted on both tracks 5161. Connecting rods 5163 are hinged to both electric sliding blocks 5162, and sliding rods 5164 are hinged to both connecting rods 5163. The sliding rods 5164 pass through the circular hole 5021, and a plug 5165 is installed on the top of the sliding rods 5164. When the storage box 502 needs to be cleaned, the electric sliding blocks 5162 drive the connecting rods 5163 to slide away from each other, thereby causing the sliding rods 5164 to move down, which in turn causes the plugs 5165 to seal the circular hole 5021, preventing a large amount of metal debris from entering the filter box 512.

[0044] like Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the metal scrap cleaning assembly 6 includes a reciprocating screw 601, a folding protective sleeve 602, a scraper 603, a pressing groove 6031, a fitting groove 6032, a collection groove 618, an output port 619, a cover plate 620, a sealing ring 621, a push rod 622, and a return spring 623.

[0045] A reciprocating screw 601 is rotatably mounted inside the storage box 502, located below the magnetic roller 503. A scraper 603 is slidably mounted on the reciprocating screw 601, with multiple fitting grooves 6032 on its top, each corresponding to a different position of the magnetic roller 503. An output port 619 is located on the side of the storage box 502 near the sprocket 505. A cover plate 620 is hinged to the bottom of the storage box 502, with a sealing ring 621 mounted on it, which engages with the output port 619. A stop rod 622 is mounted on the cover plate 620, passing through the output port 619. The end of the cover plate 620 is flush with the storage box. The storage box 502 is connected to the return spring 623. A folding protective sleeve 602 is fitted on the reciprocating screw 601. The reciprocating screw 601 rotates by driving force. When the magnetic roller 503 and the storage box 502 need to be cleaned, the reciprocating screw 601 is driven to rotate slowly. Under the rotation of the reciprocating screw 601, the scraper 603 is driven to move, cleaning the metal debris adsorbed on the multiple magnetic rollers 503 and the metal debris deposited at the bottom of the storage box 502. When the metal debris is scraped to the other end of the storage box 502, the scraper 603 touches the stop rod 622 and presses down, causing the sealing ring 621 to disengage from the output port 619, thereby discharging the metal debris into the collection tank 618.

[0046] The metal scrap cleaning assembly 6 also includes a driven pulley 604, a first drive wheel 605, a rotating support plate 606, a drive shaft 607, a second drive wheel 608, a ratchet 609, a driven shaft 610, a driven disc 611, a pawl 612, a reset push rod 613, an arc-shaped slide 614, a locking rod 615, a gantry frame 616, a telescopic head 617, a drive pulley 624, and a second belt 625;

[0047] A driven pulley 604 is installed at the end of the reciprocating screw 601 away from the sprocket 505. A rotating support plate 606 and a gantry frame 616 are installed in the chamber 2 near the driven pulley 604. A driving shaft 607 is rotatably mounted on the rotating support plate 606. A second drive wheel 608 is mounted on the driving shaft 607. A first drive wheel 605 is mounted on the rotating shaft 508. A drive belt is fitted onto the first drive wheel 605 and the second drive wheel 608. A ratchet 609 is installed at the other end of the driving shaft 607. A driven shaft 610 is rotatably mounted in the chamber 2, coaxial with the driving shaft 607. A driven disc 611 is installed at the end of the driven shaft 610 near the ratchet 609. A pawl 612 is rotatably mounted on the driven disc 611. An arc-shaped slide 614 is provided on the driven disc 611. The other end of 2 is equipped with a locking rod 615, the end of which is locked in the arc-shaped slide rail 614. A reset push rod 613 is installed on the driven plate 611, and the output end of the reset push rod 613 contacts the pawl 612. A telescopic head 617 is installed on the gantry 616, and the telescopic head 617 is located directly above the ratchet 609. A drive pulley 624 is installed at the end of the driven shaft 610 away from the driven plate 611. A second belt 625 is sleeved between the drive pulley 624 and the driven pulley 604. When the magnetic roller 503 and the storage box 502 need to be cleaned, the telescopic head 617 retracts, and the reset push rod 613 pushes the pawl 612 to contact the ratchet 609, so that the driven plate 611 and the ratchet 609 rotate synchronously, thereby driving the drive pulley 624 on the driven shaft 610 to rotate, providing driving force for the reciprocating screw 601.

[0048] The telescopic head 617 is electrically connected to the electric sliding block 5162. In its initial state, the telescopic head 617 presses down the pawl 612 so that the pawl 612 does not contact the ratchet 609.

[0049] Working principle of the invention:

[0050] When engraving the gravure roller is required, the roller is clamped in the fixture 108. The longitudinal slide rail 102 and the transverse slide rail 101 drive the sliding table 103 to move in the XY plane. The compensating rod 104 drives the rough engraving drill bit 105 and the laser head 106 to move and rotate in the Z direction. The rotating motor 117 is started, and the worm gear 110 and the worm 111 mesh to drive the fixture 108 to rotate slowly, thereby enabling the rough engraving drill bit 105 and the laser head 106 to engrave the gravure roller at multiple angles. After roughing out the general outline, the laser head 106 is used to carve the details to achieve a rapid carving effect. When the roughing drill bit 105 is processing the gravure roller, the position of the nozzle 116 is adjusted by the electric slide rail 112 and the lifting platform 113, and the angle of the coolant output by the nozzle 116 is adjusted by rotating the telescopic rod 115, thereby reducing the temperature at the contact point between the roughing drill bit 105 and the gravure roller during processing and preventing the processing chips from spreading in the air under the action of impact.

[0051] When the engraving roller is being used, the drive motor 506 is started to drive multiple magnetic rollers 503 to rotate slowly. As the coolant carries iron filings down, the larger metal filings are first filtered through the filter grid 501 and then flow into the storage box 502. Before the cutting fluid falls to the bottom of the storage box 502, the magnetic rollers 503 adsorb the metal filings that can be adsorbed. The non-adsorbable metal filings and cutting fluid flow out through the round hole 5021. After flowing into the filter box 512, the cutting fluid is filtered through the first filter chamber 5131, the second filter chamber 5132 and the third filter chamber 5133 and then sucked out by the circulation pump 515. It is then fed into the supply tank 114, thus completing the multi-stage filtration and recycling of the cutting fluid.

[0052] When the storage box 502 needs cleaning, the electric sliding block 5162 drives the connecting rod 5163 to slide away from each other, thereby causing the sliding rod 5164 to move down, which in turn causes the plug 5165 to seal the round hole 5021, preventing a large amount of metal debris from entering the filter box 512.

[0053] When the magnetic rollers 503 and storage box 502 need cleaning, the telescopic head 617 retracts, and the reset push rod 613 pushes the pawl 612 to contact the ratchet 609, thereby causing the driven disc 611 and the ratchet 609 to rotate synchronously, thereby driving the drive pulley 624 on the driven shaft 610 to rotate, providing driving force for the reciprocating screw 601. The reciprocating screw 601 rotates slowly, and under the rotation of the reciprocating screw 601, the scraper 603 moves to clean the metal debris adsorbed on the multiple magnetic rollers 503 and the metal debris deposited at the bottom of the storage box 502. When the metal debris is scraped to the other end of the storage box 502, the scraper 603 touches the stop rod 622 and presses down, causing the sealing ring 621 to disengage from the output port 619, thereby discharging the metal debris into the collection tank 618.
