Description

Technical Field

[0001] This application relates to the field of metal sputtering coating, and more particularly to a pretreatment apparatus for sputtering coating of gravure prints. Background Technology

[0002] Metal intaglio printing is a technique that uses metal engraving tools to carve desired patterns onto a metal plate. Because metal itself has a high reflectivity, metal intaglio prints with patterns have a more dazzling appearance and can be more realistic and have richer depth and perspective compared to direct printing.

[0003] Some metal gravure prints use precious metals, such as gold and silver. These precious metals are relatively soft, and metal gravure prints made of precious metals are prone to surface scratches during repeated handling and transportation. Because gravure prints are greatly affected by scratches on the surface, sputtering coating is now commonly used to protect precious metal gravure prints. Sputtering coating uses electrons or high-energy lasers to bombard the target material, causing surface components to be sputtered out in the form of atomic clusters or ions, and finally deposited on the surface of the precious metal gravure print, undergoing a film formation process to ultimately form a thin film.

[0004] Because gravure printing is processed using metal engraving tools during production, impurities such as metal shavings, dust, and even grease may adhere to the surface of the gravure print. If a coating is applied directly, the coating may not be applied evenly or may not adhere well to the surface. Therefore, there is an urgent need for a pre-treatment device that can clean the surface of gravure prints. Summary of the Invention

[0005] In order to reduce impurities adhering to the surface of gravure prints, this application provides a pretreatment device for sputtering coating of gravure prints.

[0006] This application provides a pretreatment device for sputtering coating of gravure prints, which adopts the following technical solution:

[0007] A pretreatment device for sputtering coating of gravure prints includes a tank, an ultrasonic transmitter, and a conveying assembly. The tank is used to dispense a cleaning solution for cleaning gravure prints. The ultrasonic transmitter is disposed on the inner wall of the tank. The conveying assembly is used to move the gravure prints in and out of the tank.

[0008] By adopting the above technical solution, the cleaning fluid in the pool is used to remove oil stains and dust from the gravure print. The ultrasonic transmitter causes the cleaning fluid to vibrate, creating a cavitation effect that separates metal shavings from the gravure print. Because the ultrasonic transmitter emits a high frequency of ultrasound, if the ultrasonic transmitter is constantly in operation while the gravure print is placed in the pool, the cleaning fluid may pose a hazard to the human body. The delivery component reduces the contact between the worker and the cleaning fluid during operation, ensuring the worker's safety. The ultrasonic transmitter is used to clean the gravure print, reducing impurities adhering to the surface of the print.

[0009] Optionally, the conveying assembly includes a mounting frame, two vertical moving parts, and a conveyor. The two vertical moving parts are distributed along the length of the pool body. The two vertical moving parts are respectively used to move the gravure print towards the bottom of the pool body and to move the gravure print away from the bottom of the pool body. Each vertical moving part includes two synchronous pulleys, a synchronous belt, and several receiving plates. The mounting frame is disposed in the pool body. The synchronous pulleys are distributed vertically and rotatably connected to the mounting frame. The synchronous belt is sleeved on the two synchronous pulleys. The receiving plates are distributed circumferentially along the synchronous belt and are disposed on the synchronous belt. The pool body is provided with a drive assembly for driving the two synchronous belts to move in opposite directions. The conveyor is used to move the gravure print along the distribution direction of the two vertical moving parts.

[0010] By adopting the above technical solution, the worker places the gravure print on the receiving plate in one of the vertical moving parts. The drive component drives the synchronous wheel to rotate, which in turn drives the synchronous belt to rotate. The synchronous belt moves the receiving plate, which moves the bottom of the gravure print tank until the gravure print enters the cleaning solution. Then, the conveyor is used to send the gravure print to another vertical moving part, where the gravure print abuts against the receiving plate of the other vertical moving part. The drive component drives the vertical moving part to move the gravure print away from the bottom wall of the tank until the gravure print is removed from the cleaning solution. After that, the worker removes the gravure print from the tank. The conveyor component reduces the worker's contact with the cleaning solution in the tank and eliminates the need to periodically turn the ultrasonic transmitter on and off, thus improving the cleaning efficiency of the gravure print.

[0011] Optionally, the drive assembly includes a drive motor, two drive shafts, two bevel gears, and an idler gear. The two drive shafts correspond one-to-one with two vertical moving parts. Each drive shaft is coaxially arranged with one of the synchronous pulleys. The drive shaft is rotatably connected to the mounting bracket. The synchronous pulley is mounted on the drive shaft. Each of the two bevel gears corresponds one-to-one with the two drive shafts. Each bevel gear is coaxially arranged with the drive shaft and mounted on the drive shaft. The idler gear is rotatably connected to the mounting bracket and meshes with the two bevel gears. The drive motor is used to drive one of the drive shafts to rotate.

[0012] By adopting the above technical solution, the drive motor drives one of the drive shafts to rotate, the drive shaft drives the corresponding bevel gear to rotate, the bevel gear drives the idler gear to rotate, and the idler gear drives the other bevel gear to rotate. The idler gear makes the two bevel gears rotate in opposite directions, so the two drive shafts rotate in opposite directions. The drive shaft drives the corresponding synchronous pulleys on the two vertical moving parts to rotate, and the two synchronous belts rotate in opposite directions. This realizes that the same motor drives two conveyor belts to rotate in opposite directions. The drive assembly has a simple structure and is easy for operators to operate.

[0013] Optionally, the conveying component includes two conveying rollers, a conveyor belt, and a cooperating gear. The two conveying rollers are distributed along the length of the pool body and are rotatably connected to the mounting frame. The conveyor belt is sleeved on the two conveying rollers. The cooperating gear is coaxially arranged with the idler wheel and is located on one end of the idler wheel. The cooperating gear meshes with the conveyor belt.

[0014] By adopting the above technical solution, during the process of the drive motor driving the two vertical moving parts to rotate, the idler wheel keeps rotating, and the idler wheel will drive the cooperating gear to rotate. The two conveyor rollers cut off the transmission direction of the conveyor belt, and the cooperating gear drives the conveyor belt to rotate, thus realizing that one drive motor drives the two vertical moving parts to move, and the conveyor parts move, without the need for an additional drive device.

[0015] Optionally, the pool body is provided with two conveying assemblies, which are distributed along the width direction of the pool body. The mounting bracket is slidably connected to the pool body along the width direction of the pool body. The pool body is provided with an adjusting assembly for adjusting the distance between the two mounting brackets. The adjusting assembly includes two adjusting racks, an adjusting gear, and a locking member. The two adjusting racks correspond one-to-one with the two mounting brackets. The adjusting racks are disposed on the mounting brackets, and their lengths are parallel to the width direction of the pool body. The adjusting gear is disposed on the pool body, and the two adjusting racks are located on both sides of the adjusting gear. The adjusting racks mesh with the adjusting gear, and the locking member is used to restrict the rotation of the adjusting gear.

[0016] By adopting the above technical solution, since gravure prints vary in size, larger prints are less likely to have their center of gravity placed on the receiving plate. With two conveying components distributed along the width direction, the prints can be placed on the receiving plates of two vertically moving components distributed along the width direction, reducing the likelihood of prints falling during transport. For prints of different sizes, the operator can adjust the distance between the two conveying components to ensure more reasonable placement. When the operator needs to adjust the distance between the two conveying components, they rotate the adjusting gear. The adjusting gear moves the two adjusting racks closer together or further apart, changing the distance between the two mounting brackets. After adjustment, the locking component locks the adjusting gear, preventing it from rotating and fixing the distance between the two mounting brackets.

[0017] Optionally, the locking element includes a locking block and a locking spring. The locking block is slidably connected to the pool body along the radial direction of the adjusting gear. The locking block is used to engage with the adjusting gear, and the locking spring is used to keep the locking block engaged with the adjusting gear.

[0018] By adopting the above technical solution, when the operator needs to rotate the adjusting gear, the operator needs to move the locking block away from the adjusting gear by overcoming the elastic force of the locking spring. After the adjusting gear has finished rotating, the operator releases the locking block, and the locking block moves towards the adjusting gear under the action of the locking spring until the locking block is engaged with the adjusting gear, thus locking the adjusting gear. The locking component has a simple structure and is easy for the operator to operate.

[0019] Optionally, the drive assembly further includes two first drive bevel gears and two second drive bevel gears. The drive motor is a dual-head motor. The two first drive bevel gears correspond one-to-one with the two mounting brackets. The first drive bevel gears are rotatably connected to the mounting brackets. The two first drive bevel gears are slidably connected to the two output shafts of the drive motor. The two second drive bevel gears correspond one-to-one with the two mounting brackets. The second drive bevel gears are disposed on one end of one of the synchronous pulleys. The two second drive bevel gears correspond one-to-one with the two first drive bevel gears. The first drive bevel gears mesh with the second drive bevel gears.

[0020] By adopting the above technical solution, the two conveying components need to move the gravure print simultaneously. Therefore, the conveying components have the same speed. The drive motor is a double-headed motor, and the two output shafts of the double-headed motor rotate at the same speed. The two first drive bevel gears are slidably connected to the output shafts of the double-headed motor, which realizes that the rotation speed of the two first drive bevel gears is the same. Moreover, the two drive bevel gears can be adjusted according to the different distances between the two mounting frames, and the first drive bevel gear and the second drive bevel gear are kept in a meshed state. The second drive bevel gear is used to drive the corresponding vertical moving parts in the two conveying components to move. The drive component realizes the simultaneous movement of the two conveying components and is suitable for mounting frames with different distances.

[0021] Optionally, the conveying assembly further includes two adaptors suitable for gravure prints of different sizes. The two adaptors correspond one-to-one with two vertical moving parts. Each adaptor includes an adaptor frame, two adaptor wheels, an adaptor timing belt, and several adaptor plates. The adaptor frame is slidably connected to the mounting frame along the length of the pool body. The two adaptor wheels correspond one-to-one with the two timing wheels. The adaptor wheels and timing wheels are coaxially arranged. The adaptor timing belt is sleeved on the two timing wheels. Several adaptor plates are distributed circumferentially along the adaptor timing belt. The adaptor plates are disposed on the adaptor timing belt. One of the adaptor wheels is slidably connected to the drive shaft.

[0022] By adopting the above technical solution, the adaptor further enables the gravure print to be placed stably on the receiving plate. The adaptor plate also serves as part of the gravure print receiving plate, making the placement of the gravure print more stable. When the size of the gravure print is too large and it is unstable when placed on the receiving plate, the operator can slide the adaptor frame on the mounting frame, increasing the distance between the adaptor timing belts. The gravure print is supported by two receiving plates and two adaptor plates, making the placement of the gravure print more stable. Furthermore, the drive shaft can drive the adaptor wheel to rotate, so that the rotation speed of the adaptor wheel is the same as that of the timing wheel. The adaptor timing belts rotate in the same direction and at the same speed as the timing belts. The receiving plates and adaptor plates rotate in the same direction and at the same speed. The adaptor structure is reasonable, and the pool can clean larger gravure prints.

[0023] Optionally, the conveying assembly is further provided with a control component for controlling the distance between the adaptor and the vertical moving component. The control component includes a bidirectional screw, a worm gear, and a worm. The length direction of the bidirectional screw is parallel to the length direction of the pool body. The bidirectional screw is rotatably connected to the mounting frame. The two adaptor frames are respectively threaded to the threaded sections of the bidirectional screw with opposite directions of rotation. The worm gear is coaxially arranged with the bidirectional screw and is located at one end of the bidirectional screw. The worm is rotatably connected to the mounting frame and meshes with the worm gear.

[0024] By adopting the above technical solution, when the operator needs to change the distance between the adaptive component and the vertical moving component, the operator can rotate the worm gear, which drives the worm wheel to rotate, and the worm wheel drives the bidirectional screw to rotate. The bidirectional screw causes the two control components to move closer or further apart, changing the distance between the control components and the vertical moving component. The change in distance between the control components and the vertical moving component is the same, without the need for multiple adjustments. The worm gear has a self-locking effect, so the position between the control components and the vertical moving component will not change during the cleaning process of the pool.

[0025] Optionally, the pool body is provided with a receiving component for receiving precious metal residue. The receiving component includes a receiving frame, a sealing strip, a filter screen, and a sealing element. A through groove is formed on the inner side wall of the pool body. The receiving frame is slidably connected to the through groove. The filter screen is disposed in the receiving frame. The sealing strip is disposed on the receiving frame. The sealing element is used to keep the sealing strip abutting against the side wall of the pool body.

[0026] By adopting the above technical solution, since there will be metal shavings left on the gravure print, the ultrasonic transmitter will shake the metal shavings into the pool. The metal needs to be recycled. When the gravure print is cleaned and there are metal shavings that need to be cleaned, the staff first pours out the cleaning solution from the pool. Then, the staff slides the receiving frame out of the through groove. The filter screen in the receiving frame separates the cleaning solution, and the metal shavings are left on the filter screen so that the staff can collect the metal shavings. After collection, the receiving frame is slid back into the through groove. The sealing element is used to abut the sealing strip against the pool body, reducing the amount of cleaning solution in the pool flowing out of the through groove during the cleaning of the gravure print.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Ultrasonic transmitters are used to clean and remove impurities from the surface of gravure prints;

[0029] 2. The conveyor assembly is used to move the gravure prints in and out of the pool, reducing direct contact between workers and the cleaning solution inside the pool;

[0030] 3. The drive assembly is used to simultaneously drive two vertical moving parts and the conveyor;

[0031] 4. Two conveying components and two adapters are included in the conveying components, which enable gravure prints of different sizes to be cleaned in the pool. Attached Figure Description

A guide slope is provided between the lower end face of the sealing block 641 and the side wall of the sealing block 641 facing the abutment plate 65.

[0052] The implementation principle of a pretreatment device for sputtering coating of gravure prints according to an embodiment of this application is as follows: The operator first adjusts the distance between the two mounting frames 31 according to the size of the gravure print to be cleaned. The operator can first hold the locking disc 435, which drives the locking block 431 to move away from the adjusting gear 42 through the locking rod 434. During this process, the locking spring 432 is compressed. When the locking block 431 moves away from the adjusting gear 42, the operator can rotate the adjusting disc 44. The adjusting disc 44 drives the adjusting gear 42 to rotate. The adjusting gear 42 drives the two adjusting racks 41 to move closer or further apart. The adjusting racks 41 drive the mounting frame 31 to move within the pool 1 until the mounting frame 31 is adjusted to the appropriate size of the gravure print.

[0053] Next, the staff adjusts the adaptor 34 according to the size of the gravure print. The staff rotates the rotating disk 354, which drives the worm gear 353 to rotate. The worm gear 353 drives the worm wheel 352 to rotate, which in turn drives the double-ended screw 351 to rotate. The double-ended screw 351 moves the two adaptors 34 closer or further apart until the distance between the adaptor 34 and the vertical moving part 32 is suitable for the size of the gravure print. Then, the staff starts the drive motor 51. The drive motor 51 drives the two first drive bevel gears 56 to rotate, which in turn drives the second drive bevel gear 57 to rotate. The second drive bevel gear 57 then drives the drive shaft 52 to rotate. The two drive shafts 52 are aligned in a straight line. The two bevel gears 53 and the idler gear 54 work together to achieve rotation in opposite directions. The drive shaft 52 drives the synchronous pulley 321 and the adapting pulley 342 to rotate. The synchronous pulley 321 drives the synchronous belt 322 to rotate, and the adapting pulley 342 drives the adapting synchronous belt 343 to rotate. The synchronous pulley 321 drives the receiving block to move, and the adapting synchronous belt 343 drives the adapting plate 344 to move. The adapting plate 344 and the receiving plate 323 work together to abut against the gravure print. During the rotation of the idler gear 54, the idler gear 54 drives the cooperating gear 333 to rotate. The cooperating gear 333 drives the conveyor belt 332 to move. The conveyor belt 332 drives the gravure print to move along the length of the pool 1. The gravure print moves in the pool 1 filled with cleaning liquid.

[0054] During the movement of the gravure print in the cleaning solution, the ultrasonic transmitter 2 generates high-frequency ultrasonic waves. The ultrasonic waves generate impact force to separate the gravure print from metal shavings and other impurities. The separated metal shavings and impurities fall into the receiving frame 61. After cleaning, the gravure print moves away from the pool body 1 under the action of the vertical moving part 32 and the adapting part 34. When there are many metal shavings in the receiving frame 61, the operator can move the sealing block 641 vertically upward until the sealing block 641 is separated from the abutment plate 65. Then, the operator holds the handle and removes the receiving frame 61 from the through groove 11. The cleaning solution will flow out from the filter screen 63, and the metal shavings will remain on the filter screen 63, making it easy for the operator to clean and collect the metal shavings. After the metal shavings are collected, the operator moves the receiving frame 61 towards the through groove 11 again, and then abuts the locking block 431 against the end of the abutment plate 65 away from the receiving frame 61, so that the sealing strip 62 abuts against the outer wall of the pool body 1, maintaining the sealing of the pool body 1.

[0055] 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.
