Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting mark printing, in particular to a flexographic printing vacuum aluminum plating system with anti-counterfeiting marks and a production process. Background Art

[0002] Anti-counterfeiting marks, also known as anti-counterfeiting labels or anti-counterfeiting stickers, are a type of product that can be pasted, transferred, or attached to the surface of the subject matter, or to the packaging of the subject matter, or to the subject matter's accessories (such as product tags and anti-counterfeiting cards), and have an anti-counterfeiting effect. The anti-counterfeiting features and identification methods of anti-counterfeiting marks are the soul of anti-counterfeiting marks. Printed anti-counterfeiting marks usually require the anti-counterfeiting pattern to be printed on a substrate roll such as a film roll or a paper roll through vacuum aluminum plating technology. For example, Chinese patent CN101659168B discloses a flexographic printing vacuum aluminum plating system and production process with anti-counterfeiting marks.

[0003] However, the current flexographic printing vacuum aluminum plating system with anti-counterfeiting labels can only print anti-counterfeiting labels on substrate rolls, and cannot print on small or short substrates. This means that if it is necessary to print on small or short substrates, new equipment needs to be added, which will increase the cost investment. At the same time, when small or short substrates appear in the processing of the substrate, they will easily be discarded due to the inability to print anti-counterfeiting labels on them, thereby wasting resources. Therefore, a flexographic printing vacuum aluminum plating system and production process with anti-counterfeiting labels are invented. Summary of the invention

[0054] The U-shaped heating tube is used to heat the material in the aluminum plating box into aluminum vapor, and a plurality of U-shaped heating tubes are fixedly installed on the inner wall of the aluminum plating box.

[0055] The production process of flexographic printing vacuum aluminum plating with anti-counterfeiting logo includes the following specific steps:

[0056] Step 1: When it is necessary to print an anti-counterfeiting mark on a small substrate, the first fixing plate is mounted on the second sliding block by screws to realize the installation of the short substrate placement component;

[0057] Step 2: Place the short or small substrate on the placement board and make its surface flat. Afterwards, use a vacuum pump to extract the air in the vacuum suction cup to achieve adsorption and fixation of the short substrate on the placement board. At this time, the placement board is flipped by the fifth servo motor until the short substrate faces downward.

[0058] Step 3: The second servo motor is used to rotate the second screw. When the second screw rotates, the second slider moves the short substrate fixed on the placement plate until the right side of the short substrate is moved to the upper left side of the oil film attachment component.

[0059] Step 4: The first servo motor rotates the first screw. When the first screw rotates, the short strip of substrate fixed on the placement plate is lowered by the action of the first slider until the right side of the short strip of substrate contacts the top of the printing roller.

[0060] Step 5: The transfer roller is rotated by the third servo motor, and at the same time, the printing roller is rotated in the opposite direction to the transfer roller by the fourth servo motor. When the transfer roller rotates, the silicone oil is brought up and transferred to the printing roller. When the printing roller rotates, the oil film printed on the anti-counterfeiting pattern is printed on the short strip substrate. When the printing roller rotates, the short strip substrate is moved to the right by the moving component.

[0061] Step 6: When the short strip substrate is moved to the top of the aluminizing assembly by the moving assembly, the material in the aluminizing box is heated into aluminum vapor by the U-shaped heating tube. Due to the shielding effect of the oil film, the molecules of the aluminum vapor cannot adhere to the substrate, and the oil film is vaporized due to the heat after aluminizing, so a clean and clear anti-counterfeiting pattern is obtained after aluminizing, thereby completing the anti-counterfeiting pattern on the short strip substrate;

[0062] Step 7: When it is necessary to print an anti-counterfeiting mark on the long substrate roll, the second fixing plate is mounted on the second sliding block by screws to realize the installation of the substrate roll placement assembly;

[0063] Step 8: Install the substrate roll on the installation roller, and then wind one end of the substrate roll on the winding roller, and keep it straight and with a flat surface;

[0064] Step nine: The substrate between the mounting roller and the winding roller is positioned above the oil film attachment component and the aluminum plating component at the same time through the lifting component and the moving component, and contacts with the top of the printing roller;

[0065] Step 10: The sixth servo motor and the seventh servo motor are used to simultaneously rotate the installation roller and the winding roller. When the installation roller rotates, the substrate roll is released, and when the winding roller rotates, the other end of the substrate roll is wound, thereby realizing transmission and winding of the substrate roll.

[0066] Step 11: When the substrate roll is being driven and wound, the transfer roller is rotated by the third servo motor, and at the same time, the printing roller is rotated in the opposite direction to the transfer roller by the fourth servo motor. When the transfer roller rotates, the silicone oil is brought up and transferred to the printing roller. When the printing roller rotates, the oil film printed on the anti-counterfeiting pattern is printed on the substrate;

[0067] Step 12: When the anti-counterfeiting pattern oil film printed on the substrate moves to the top of the aluminum-plated component, the material in the aluminum-plated box is heated into aluminum vapor by the U-shaped heating tube. Due to the shielding effect of the oil film, the molecules of the aluminum vapor cannot adhere to the substrate, and the oil film is vaporized due to heat after aluminum plating. Therefore, a clean and clear anti-counterfeiting pattern is obtained after aluminum plating, thereby completing the anti-counterfeiting pattern on the substrate roll.

[0068] Compared with existing technologies:

[0069] 1. By detachably connecting the short substrate placement component or the substrate roll placement component to the moving component, it is possible to switch and print anti-counterfeiting marks on small or short substrates and substrate rolls, thereby making the device multi-purpose and improving the utilization rate of the device;

[0070] 2. By detachably connecting the short substrate placement component or the substrate roll placement component to the mobile component, the problem that the current flexographic printing vacuum aluminum plating system with anti-counterfeiting labels can only print anti-counterfeiting labels on substrate rolls can be solved. Therefore, when it is necessary to print on small or short substrates, only the short substrate placement component needs to be installed without adding new equipment, thereby reducing the cost investment and further saving resources;

[0071] 3. The short strip substrate is adsorbed and fixed on the placement board by the fixing component, which facilitates the fixing of the short strip substrate and makes the surface of the placement board free of obstacles, which is convenient for later printing;

[0072] 4. Through the coordinated use of oil film attachment components and aluminum-plated components, it is possible to form an anti-counterfeiting pattern on the substrate with clear layers, distinct dark and light, lifelike images and a heavy metal texture. BRIEF DESCRIPTION OF THE DRAWINGS

[0100] The production process of flexographic printing vacuum aluminum plating with anti-counterfeiting logo includes the following specific steps:

[0101] Step 1: When it is necessary to print an anti-counterfeiting mark on a small substrate, the first fixing plate 61 is mounted on the second slider 33 by screws to install the short substrate placement assembly 60;

[0102] Step 2: Place a short or small substrate on the placement plate 64 and make its surface flat. Afterwards, the vacuum pump 653 extracts the air in the vacuum suction cup 652 to achieve adsorption and fixation of the short substrate on the placement plate 64. At this time, the placement plate 64 is turned over by the fifth servo motor 63 until the short substrate faces downward.

[0103] Step 3: The second servo motor 35 rotates the second screw 32. When the second screw 32 rotates, the second slider 33 moves the short substrate fixed on the placement plate 64 until the right side of the short substrate is moved to the upper left side of the oil film attachment assembly 40.

When the printing roller 45 rotates, the short strip substrate is moved to the right by the moving assembly 30.

[0106] Step six: When the short strip substrate is moved to the top of the aluminum plating component 50 by the moving component 30, the material in the aluminum plating box 51 is heated into aluminum vapor by the U-shaped heating tube 52. Due to the shielding effect of the oil film, the molecules of the aluminum vapor cannot adhere to the substrate, and the oil film is vaporized due to heat after aluminum plating. Therefore, a clean and clear anti-counterfeiting pattern is obtained after aluminum plating, thereby completing the anti-counterfeiting pattern on the short strip substrate.

[0107] Embodiment 2:

[0108] The present invention provides a flexographic printing vacuum aluminum plating system with anti-counterfeiting mark, please refer to Figure 7-Figure 9 The substrate roll placement assembly 70 includes: a second fixing plate 71, a support rod 72, a square plate 73, and an installation assembly for rolling up the substrate roll;

[0112] The production process of flexographic printing vacuum aluminum plating with anti-counterfeiting logo includes the following specific steps:

[0113] Step 1: When it is necessary to print an anti-counterfeiting mark on a long substrate roll, the second fixing plate 71 is installed on the second slider 33 by screws to install the substrate roll placement assembly 70;

[0114] Step 2: Install the substrate roll on the installation roller 74, and then wind one end of the substrate roll on the winding roller 76, and keep it in a straight state with a flat surface;

[0115] Step 3: The substrate between the mounting roller 74 and the winding roller 76 is positioned above the oil film attachment component 40 and the aluminum plating component 50 at the same time through the lifting component 20 and the moving component 30, and contacts the top of the printing roller 45;

[0116] Step 4: The sixth servo motor 75 and the seventh servo motor 77 are used to simultaneously rotate the installation roller 74 and the winding roller 76. When the installation roller 74 rotates, the substrate roll is released, and when the winding roller 76 rotates, the other end of the substrate roll is wound, thereby realizing the transmission and winding of the substrate roll.

[0117] Step 5: When the substrate roll is being driven and wound, the transfer roller 43 is rotated by the third servo motor 44, and at the same time, the printing roller 45 is rotated in the opposite direction to the transfer roller 43 by the fourth servo motor 46. When the transfer roller 43 rotates, the silicone oil 42 is brought up and transferred to the printing roller 45.

[0118] Step six: When the oil film of the anti-counterfeiting pattern printed on the substrate moves to the top of the aluminum plating component 50, the material in the aluminum plating box 51 is heated into aluminum vapor by the U-shaped heating tube 52. Due to the shielding effect of the oil film, the molecules of the aluminum vapor cannot adhere to the substrate, and the oil film is vaporized due to heat after aluminum plating. Therefore, a clean and clear anti-counterfeiting pattern is obtained after aluminum plating, thereby completing the anti-counterfeiting pattern on the substrate roll.

4. The production process of flexographic printing vacuum aluminum plating with anti-counterfeiting mark is characterized by: The specific steps are as follows: Step 1: When it is necessary to print an anti-counterfeiting mark on a small piece of substrate, the first fixing plate (61) is mounted on the second sliding block (33) by means of screws, so as to realize the installation of the short strip substrate placement component (60); Step 2: placing a short or small substrate on the placement plate (64) and making its surface flat, then extracting air from the vacuum suction cup (652) through a vacuum pump (653) to achieve adsorption and fixation of the short strip of substrate on the placement plate (64), and at this time, turning the placement plate (64) over through a fifth servo motor (63) until the short strip of substrate faces downward; Step 3: The second screw (32) is rotated by the second servo motor (35). When the second screw (32) rotates, the short strip substrate fixed on the placement plate (64) is moved under the action of the second slider (33) until the right side of the short strip substrate is moved to the upper left side of the oil film attachment component (40); Step 4: The first servo motor (25) is used to rotate the first screw rod (22). When the first screw rod (22) rotates, the first slider (23) causes the short strip of substrate fixed on the placement plate (64) to descend until the right side of the short strip of substrate contacts the top end of the printing roller (45); Step 5: The transfer roller (43) is rotated by the third servo motor (44), and at the same time, the printing roller (45) is rotated in the opposite direction to the transfer roller (43) by the fourth servo motor (46). When the transfer roller (43) rotates, the silicone oil (42) is brought up and the brought up silicone oil (42) is transferred to the printing roller (45). When the printing roller (45) rotates, the oil film printed on the anti-counterfeiting pattern is printed on the short strip substrate. When the printing roller (45) rotates, the short strip substrate is moved to the right by the moving component (30); Step 6: When the short strip substrate is moved to the top of the aluminum plating component (50) by the moving component (30), the material in the aluminum plating box (51) is heated into aluminum vapor by the U-shaped heating tube (52). Due to the shielding effect of the oil film, the molecules of the aluminum vapor cannot adhere to the substrate, and the oil film is vaporized due to the heat after aluminum plating. Therefore, a clean and clear anti-counterfeiting pattern is obtained after aluminum plating, thereby completing the anti-counterfeiting pattern on the short strip substrate; Step 7: When it is necessary to print an anti-counterfeiting mark on the long substrate roll, the second fixing plate (71) is mounted on the second sliding block (33) by means of screws, so as to realize the installation of the substrate roll placement assembly (70); Step 8: Install the substrate roll on the installation roller (74), and then wind one end of the substrate roll on the winding roller (76), and keep it in a straight state with a flat surface; Step nine: by means of the lifting assembly (20) and the moving assembly (30), the substrate between the mounting roller (74) and the winding roller (76) is simultaneously located above the oil film attachment assembly (40) and the aluminum plating assembly (50), and is in contact with the top end of the printing roller (45); Step ten: The sixth servo motor (75) and the seventh servo motor (77) are used to simultaneously rotate the installation roller (74) and the winding roller (76); when the installation roller (74) rotates, the substrate roll is released; and when the winding roller (76) rotates, the other end of the substrate roll is wound, thereby realizing transmission and winding of the substrate roll; Step 11: When the substrate roll is being driven and wound, the transfer roller (43) is rotated by the third servo motor (44), and at the same time, the printing roller (45) is rotated in the opposite direction to the transfer roller (43) by the fourth servo motor (46). When the transfer roller (43) rotates, the silicone oil (42) is carried up and the carried silicone oil (42) is transferred to the printing roller (45). When the printing roller (45) rotates, the oil film printed on the anti-counterfeiting pattern is printed on the substrate; Step 12: When the anti-counterfeiting pattern oil film printed on the substrate moves to the top of the aluminum plating component (50), the material in the aluminum plating box (51) is heated into aluminum vapor by the U-shaped heating tube (52). Due to the shielding effect of the oil film, the molecules of the aluminum vapor cannot adhere to the substrate, and the oil film is vaporized due to the heat after aluminum plating. Therefore, a clean and clear anti-counterfeiting pattern is obtained after aluminum plating, thereby completing the anti-counterfeiting pattern on the substrate roll.
