Abstract
Description
Technical Field
[0001] This application relates to the field of gravure printing equipment, and more particularly to a cleaning device for precious metal gravure prints. Background Technology
[0002] Currently, precious metal gravure printing sputtering coating is a commonly used surface treatment technique for adding precious metal coatings to gravure prints, enhancing the visual effect and texture of the artwork. This process mainly includes the following steps:
[0003] Preparation: Prepare the substrate for the gravure print, usually a metal plate. Perform necessary sanding and cleaning to ensure a smooth and free surface.
[0004] Creating an intaglio print involves engraving a designed pattern onto a metal plate, creating a recessed image. This process can be accomplished using methods such as chemical etching or mechanical engraving.
[0005] Sputtering coating: Precious metals (such as gold and silver) are processed into metallic gases. Then, the metallic gases are sprayed onto the surface of the gravure print using sputtering technology. During this process, the metallic gases deposit on the surface of the gravure print, forming a uniform and smooth coating.
[0006] Sputtering coating technology for precious metal intaglio prints can give the artwork a unique texture and luster, enhancing its collection and appreciation value.
[0007] The engraved intaglio print is prone to having impurities, such as metal shavings, remaining in the recessed pattern. This can cause the print to contain metal shavings during subsequent processing, thus affecting its quality. Summary of the Invention
[0008] In order to reduce the residual metal debris on the engraved surface of gravure prints and improve the quality of the finished gravure prints, this application provides a cleaning device for precious metal gravure prints.
[0009] This application provides a cleaning device for precious metal gravure prints, which adopts the following technical solution:
[0010] A cleaning device for precious metal gravure prints includes a frame and a drive assembly. The frame is connected to a support plate for placing the gravure print. A rinsing head and a blower head are provided on one side of the support plate. The rinsing head is connected to a water source, and the blower head is connected to an air source. Both the rinsing head and the blower head face the engraved surface of the gravure print and are connected to the drive assembly. The drive assembly is used to move the rinsing head and the blower head to adjust the orientation of the rinsing head and the blower head towards the engraved surface.
[0011] By adopting the above technical solution, after the gravure print is placed on the carrier plate, the water supply source can supply water to the rinsing head, which can spray water on the engraved surface of the gravure print to rinse it and remove residual metal debris. The air supply source can supply air to the blower head, which can blow air on the engraved surface of the gravure print to remove residual metal debris and dry the residual water. After the drive component drives the rinsing head and the blower head to move, the rinsing head and the blower head can clean different parts of the engraved surface of the gravure print, thereby reducing the residual metal debris on the engraved surface and improving the quality of the processed gravure print.
[0012] Preferably, the support plate has a limiting groove for accommodating the gravure print, the bottom of the limiting groove has a cleaning hole, the support plate is connected to a limiting component for fixing the gravure print, and the rinsing head and the blower head are both located below the support plate.
[0013] By adopting the above technical solution, after the gravure print is placed in the limiting groove, the engraved surface of the gravure print faces the cleaning hole. The limiting component fixes and limits the gravure print, which can improve the stability of the gravure print when cleaning the engraved surface. When the rinsing head and the blower head clean the engraved surface of the gravure print from below, it is easy for metal debris and water droplets to detach from the engraved surface of the gravure print, thereby improving the cleaning effect of the engraved surface of the gravure print.
[0014] Preferably, the limiting component includes a bracket, a first lifting member, and a pressure plate. The bracket is connected to the top of the bearing plate, the first lifting member is connected to the bracket, and the pressure plate is connected to the first lifting member. The first lifting member is used to lift the pressure plate so that the pressure plate presses down on the gravure print or moves away from the gravure print.
[0015] By adopting the above technical solution, after the gravure print is placed in the limiting groove, the first lifting component lowers the pressure plate until the pressure plate presses onto the gravure print, which can improve the stability of the gravure print in the limiting groove. After the engraved surface of the gravure print is cleaned, the first lifting component raises the pressure plate, the pressure plate separates from the gravure print, and the gravure print can be taken out from the limiting groove.
[0016] Preferably, the bottom of the pressure plate is provided with a suction cup, and the bottom of the pressure plate has a receiving groove. The top of the suction cup is detachably connected to the bottom of the pressure plate through the receiving groove. The bottom of the suction cup has an opening, and the top of the suction cup has a vent hole that communicates with the bottom opening of the suction cup. A plug is detachably connected to the top of the suction cup, and the plug is inserted into the suction cup through the vent hole. When the pressure plate presses down on the gravure print, the suction cup is used to adhere to the gravure print.
[0017] By adopting the above technical solution, when the pressure plate presses down on the gravure print through the suction cup, the gas in the suction cup is squeezed out, and the suction cup can hold the gravure print, which can improve the stability of the gravure print in the limiting groove. After the first lifting component raises the pressure plate, the suction cup is removed from the pressure plate, and the plug in the vent hole is pulled out, which can facilitate the separation of the suction cup from the gravure print.
[0018] Preferably, an electromagnet is embedded in the receiving groove, and a magnetic ring is embedded in the top of the suction cup. After the top of the suction cup is inserted into the bottom of the pressure plate, the magnetic ring is attracted to the electromagnet.
[0019] By adopting the above technical solution, when the electromagnet is energized, the top of the suction cup can be attracted to the receiving groove by the magnetic ring. When the electromagnet is de-energized, the pressure plate can separate from the suction cup when it rises, which makes it easy to separate the suction cup from the pressure plate.
[0020] Preferably, the frame is rotatably equipped with a gear, the gear meshes with a toothed ring, the toothed ring is sleeved and fixed to the bearing plate, and the limiting groove is located on the central axis of the toothed ring.
[0021] By adopting the above technical solution, the gear can drive the gear ring to rotate, the gear ring can drive the support plate to rotate, and the support plate can drive the gravure print in the limiting groove to rotate. When the gravure print rotates, the movement of the rinsing head and the blower head in conjunction with the drive component can facilitate the rinsing head and the blower head to face different parts of the gravure print's engraved surface, so as to clean the gravure print's engraved surface. After the rinsing head sprays water on the gravure print's engraved surface, the rotation of the gravure print can shake off the water adhering to the gravure print, which can improve the drying efficiency of the blower head on the gravure print's engraved surface.
[0022] Preferably, a rubber ring is provided below the limiting groove, and the rubber ring is connected to a second lifting member. The second lifting member is used to lift the rubber ring vertically so that the rubber ring moves into the cleaning hole and abuts against the inner peripheral wall of the cleaning hole. The top of the rubber ring is used to abut against the gravure print.
[0023] By adopting the above technical solution, the second lifting component can drive the rubber ring to rise and fall. When the second lifting component rises to the point where the rubber ring abuts against the gravure print, the rubber ring also abuts against the inner circumferential wall of the cleaning hole. The rubber ring can improve the sealing between the bottom of the gravure print and the bottom wall of the limiting groove, and can minimize the water sprayed from the rinsing head from entering between the bottom of the gravure print and the bottom wall of the limiting groove. This can minimize the water residue on the gravure print after the blower has dried the engraved surface of the gravure print. The blower can also dry the rubber ring while drying the gravure print.
[0024] Preferably, the bottom of the rubber ring is connected to multiple springs, the springs are vertically arranged and their top ends are connected to the rubber ring, the second lifting component is connected to a support ring, the central axis of the support ring is collinear with the central axis of the rubber ring, and the bottom end of the spring is connected to the top of the support ring.
[0025] By adopting the above technical solution, the second lifting component can raise and lower the rubber ring through the lifting support ring. The rubber ring abuts against the gravure print through the spring. The spring is compressed. When the limiting component separates from the gravure print, the spring returns to its original position and can lift the gravure print out of the limiting groove through the rubber ring, which makes it easy to remove the gravure print from the limiting groove.
[0026] Preferably, the drive assembly is connected to a frame, and the rinsing head and the blower head are both connected to the frame. The rinsing head and the blower head are both inclined and set at an angle. The rinsing head is connected to the water supply source through a first flexible tube, and the blower head is connected to the air supply source through a second flexible tube.
[0027] By adopting the above technical solution, the water source supplies water to the rinsing head through the first flexible pipe, and the air source supplies air to the blower head through the second flexible pipe. Both the first and second flexible pipes can be bent, which facilitates the drive assembly to move the rinsing head and the blower head through the frame. The rinsing head sprays water to the engraved surface of the gravure print at an inclined angle, which can improve the rinsing efficiency. The blower head blows air to the engraved surface of the gravure print at an inclined angle, which can improve the drying efficiency.
[0028] Preferably, the drive assembly includes a lead screw, a guide rod, a sliding block, and an electric cylinder. One end of the lead screw is connected to a servo motor. The length direction of the guide rod is consistent with the length direction of the lead screw and both are arranged horizontally. One end of the sliding block is threaded onto the lead screw, and the other end of the sliding block is slidably sleeved onto the guide rod. The electric cylinder is disposed on the sliding block. The flushing head and the blower head are both connected to the push rod of the electric cylinder. The length direction of the push rod of the electric cylinder is arranged horizontally and perpendicular to the length direction of the guide rod.
[0029] By adopting the above technical solution, the servo motor can drive the lead screw to rotate, the lead screw drives the sliding block to move on the guide rod, and the electric cylinder can drive the rinsing head and the blowing head to move on the sliding block, thereby moving the rinsing head and the blowing head so that the rinsing head and the blowing head can be directed towards different parts of the intaglio engraving surface.
[0030] In summary, this application includes at least one of the following beneficial technical effects:
[0031] 1. After the gravure print is placed on the support plate, the water supply can supply water to the rinsing head, which can spray water on the engraved surface of the gravure print to rinse it and remove any residual metal debris. The air supply can supply air to the blower head, which can blow air on the engraved surface of the gravure print to remove any residual metal debris and dry any water adhering to the surface. After the drive assembly moves the rinsing head and the blower head, they can clean different parts of the engraved surface of the gravure print, thereby reducing the amount of residual metal debris and improving the quality of the finished gravure print.
[0032] 2. The second lifting component can drive the rubber ring to rise and fall. When the second lifting component rises to the point where the rubber ring abuts against the gravure print, the rubber ring also abuts against the inner circumferential wall of the cleaning hole. The rubber ring can improve the sealing between the bottom of the gravure print and the bottom wall of the limiting groove, and can minimize the water sprayed from the rinsing head from entering between the bottom of the gravure print and the bottom wall of the limiting groove. This can minimize the water residue on the gravure print after the blower has dried the engraved surface of the gravure print. The blower can also dry the rubber ring while drying the gravure print.
[0033] 3. The second lifting component can raise and lower the rubber ring through the lifting support ring. The rubber ring abuts against the gravure print through the spring. The spring is compressed. When the limiting component separates from the gravure print, the spring returns to its original position and can lift the gravure print out of the limiting groove through the rubber ring, which makes it easy to remove the gravure print from the limiting groove.

The rinsing head 101 is used to rinse water onto the engraved surface of the gravure print 700, and the blowing head 102 is used to blow air onto the engraved surface of the gravure print 700, which can reduce the residual metal debris on the engraved surface of the gravure print 700 and improve the quality of the processed gravure print 700.
[0049] Reference Figure 1 and Figure 2 A motor is mounted on the top of the frame 100. The output shaft of the motor is connected to a gear 103, which is horizontally positioned and meshes with a gear ring 104. The gear ring 104 is rotatably mounted on the top of the frame 100 via the gear 103. A support plate 300 is horizontally positioned with its length direction aligned radially with that of the gear ring 104. Both ends of the support plate 300 along its length direction are fixed to the inner ring of the gear ring 104. A limiting groove 301 is formed on the top of the support plate 300. The limiting groove 301 is a square groove with its center located on the central axis of the gear ring 104.
[0050] Reference Figure 1 , Figure 2 and Figure 3A cleaning hole 302 is provided on the bottom wall of the limiting groove 301. The cleaning hole 302 is a square hole, and its center is located on the central axis of the toothed ring 104. The gravure print 700 is rectangular in shape. After the gravure print 700 is placed in the limiting groove 301, the bottom of the limiting groove 301 supports the engraved surface of the gravure print 700, and the engraved surface of the gravure print 700 faces the cleaning hole 302. The rinsing head 101 and the blower head 102 are both located below the cleaning hole 302.
[0051] A drive assembly 200 is provided at the bottom of the frame 100. The drive assembly 200 includes a lead screw 201, a guide rod 202, and a sliding block 203. The length directions of the lead screw 201 and the guide rod 202 are consistent with the length direction of the support plate 300. The lead screw 201 and the guide rod 202 are distributed horizontally at intervals. Both ends of the guide rod 202 are fixed to the frame 100, and both ends of the lead screw 201 are rotatably connected to the frame 100. A servo motor for driving the lead screw 201 to rotate is connected to the frame 100. The output shaft of the servo motor is connected to one end of the lead screw 201. One end of the sliding block 203 is slidably sleeved on the guide rod 202, and the other end of the sliding block 203 is threaded onto the lead screw 201. The drive assembly 200 also includes an electric cylinder 204. The housing of the electric cylinder 204 is connected to the top of the sliding block 203, and the length direction of the push rod of the electric cylinder 204 is consistent with the width direction of the support plate 300.
[0052] Reference Figure 3 The push rod end of the electric cylinder 204 is connected to the frame 105, and the rinsing head 101 and the blower head 102 are both connected to the top of the frame 105. Both the rinsing head 101 and the blower head 102 are inclined and face the cleaning hole 302, forming an angle. The rinsing head 101 is connected to a water source via a first flexible pipe 106, which is a water pump. The blower head 102 is connected to an air source via a second flexible pipe 107, which is a fan. Both the first flexible pipe 106 and the second flexible pipe 107 are made of flexible plastic.
[0053] Reference Figure 1 and Figure 3 To improve the stability of the gravure print 700 during cleaning, a limiting component 400 is provided on the top of the support plate 300. The limiting component 400 includes a bracket 401, a first lifting member 402, and a pressure plate 403. The bracket 401 is connected and fixed to the top of the support plate 300. The first lifting member 402 is a first cylinder, which is connected to the top of the bracket 401. The first cylinder is vertically set and its piston rod passes through the bracket 401 and faces the limiting groove 301. The pressure plate 403 is connected to the end of the piston rod of the first cylinder. The pressure plate 403 is a rectangular plate and is horizontally set directly above the limiting groove 301.
[0054] Reference Figure 3 , Figure 4 and Figure 5The pressure plate 403 has a receiving groove 404 at its bottom, in which an electromagnet 405 is embedded. A suction cup 500 is detachably connected to the bottom of the pressure plate 403. A vent hole 501 is provided at the top of the suction cup 500, and a plug 502 is inserted through the vent hole 501. The plug 502 is detachably connected to the top of the suction cup 500, allowing the vent hole 501 to be opened and closed. A magnetic ring 503 is embedded at the top of the suction cup 500, which is inserted into the bottom of the pressure plate 403 through the receiving groove 404. When the electromagnet 405 is energized, the magnetic ring 503 attracts the electromagnet 405, thus connecting the suction cup 500 to the pressure plate 403. The bottom opening of the suction cup 500 faces the limiting groove 301, and the vent hole 501 communicates with the bottom opening of the suction cup 500. The first cylinder drives the pressure plate 403 to descend, and the bottom of the suction cup 500 enters the limiting groove 301 and is attracted to the top surface of the gravure print 700, pressing down on the gravure print 700. After the electromagnet 405 is de-energized, the first cylinder drives the pressure plate 403 to rise, and the pressure plate 403 separates from the suction cup 500. After the operator pulls out the plug 502, the suction cup 500 is then separated from the gravure print 700.
[0055] Reference Figure 1 and Figure 3 The bracket 401 is connected to a second lifting component 601, which is a second cylinder. The second cylinder is vertically positioned with its piston rod facing the top of the support plate 300. There are two second cylinders, spaced apart along the length of the support plate 300. A support ring 603, rectangular in shape, is positioned below the support plate 300. The support ring 603 is connected to the piston rod ends of the two second cylinders via a connecting bracket, allowing the second cylinders to raise and lower the support ring 603. Multiple springs 602 are vertically positioned at the top of each side of the support ring 603, evenly spaced along the length of each side. A rectangular rubber ring 600 is positioned above the support ring 603. The bottom of each spring 602 connects to the top of the support ring 603, and the top of each spring 602 connects to the bottom of the rubber ring 600. The centers of the rubber ring 600, the support ring 603, and the cleaning hole 302 are all on the same straight line. After the second cylinder raises the support ring 603, the rubber ring 600 can be raised into the cleaning hole 302, and the top of the rubber ring 600 abuts against the bottom surface of the gravure print 700 and the outer ring of the rubber ring 600 abuts against the inner peripheral wall of the cleaning hole 302.
[0056] The implementation principle of a cleaning device for precious metal gravure prints according to an embodiment of this application is as follows: the worker places the gravure print 700 to be cleaned into the limiting groove 301 with the engraved surface of the gravure print 700 facing down. The first lifting member 402 lowers the pressure plate 403 until the suction cup 500 adsorbs the gravure print 700 and presses it down. The second lifting member 601 raises the rubber ring 600 through the support ring 603, and the rubber ring 600 abuts against the engraved surface of the gravure print 700.
[0057] Water is supplied to the rinsing head 101 through the first flexible pipe 106. The rinsing head 101 sprays water onto the engraved surface of the intaglio print 700. As the sliding block 203 moves, the electric cylinder 204 moves the frame 105, and the gear 103 rotates the support plate 300 through the gear ring 104, the rinsing head 101 can be directed toward different parts of the engraved surface of the intaglio print 700, thereby rinsing away metal debris from the engraved surface of the intaglio print 700. The water supply to the rinsing head 101 is then stopped. 1. Water and air supply are provided to the blower head 102 through the second flexible pipe 107. The blower head 102 blows air onto the engraved surface of the gravure print 700. As the sliding block 203 moves and the electric cylinder 204 moves the frame 105, and the gear 103 rotates the support plate 300 through the gear ring 104, the blower head 102 can be directed toward different parts of the engraved surface of the gravure print 700, thereby drying the water on the engraved surface of the gravure print 700 and the water on the rubber ring 600.
[0058] When the electromagnet 405 is de-energized, the first lifting component 402 raises the pressure plate 403, and the pressure plate 403 disengages from the suction cup 500. The operator pulls the plug 502 out of the vent 501 to separate the gravure print 700 from the pressure plate 403. When the electromagnet 405 is energized, the operator inserts the top of the suction cup 500 into the receiving groove 404, and the suction cup 500 is attracted to the electromagnet 405 through the magnetic ring 503.
[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
