Technical Field

[0001] This invention relates to the field of laser composite paper manufacturing technology, specifically to a novel composite manufacturing process for laser transfer paper. Background Technology

[0002] Laser transfer paper, with its stunning laser effects and excellent printability, is widely used in the packaging of high-end tobacco, alcohol, cosmetics, and gifts. Currently, the mainstream manufacturing process for laser composite paper in the industry typically employs wet lamination technology.

[0003] Although this traditional wet lamination process is widely used, its inherent technical principles have led to a series of long-standing technical problems in production practice that have not been effectively solved.

[0027] This invention provides a novel composite manufacturing process for laser transfer paper, such as... Figure 1-6As shown, the machine includes two strip-shaped frame bases 101. Two vertical main columns 117 are fixed to each of the frame bases 101 on both sides. Lifting beam mounting seats 119, which can be raised and lowered, are provided on both sides of the top of each main column 117. The lifting beam mounting seats 119 on both sides are symmetrically arranged. A main support beam 103 of a crossbeam is fixed to the top of each lifting beam mounting seat 119. Four main support beams 103 are arranged in pairs, with a lower mirror-finished cooling steel roller drive shaft 124 rotatably connected between each pair. An upper roller system mounting beam 10, which can be raised and lowered, is provided above each of the main support beams 103 on both sides. 9. A telescopic support rod 108 is installed and connected between the upper roller system mounting beam 109 and the main support crossbeam 103. The upper roller system mounting beam 109 and the main support crossbeam 103 are triangular. The four upper roller system mounting beams 109 are arranged in pairs, and each pair is provided with an upper mirror cooling steel roller drive shaft 132. Mirror cooling steel rollers 110 are fixedly connected to the outer end faces of the upper mirror cooling steel roller drive shafts 132 on both sides and the outer end face of the lower mirror cooling steel roller drive shaft 124 on one side. A rubber pressure roller 111 is fixedly connected to the outer end face of the lower mirror cooling steel roller drive shaft 124 on the other side.

[0028] It should be further explained that a drive motor is provided in the upper roller system mounting beam 109 on one side. The drive motor located in the upper roller system mounting beam 109 is poweredly connected to the drive shaft 132 of the upper mirror cooling steel roller, and the drive motor located in the main support beam 103 is poweredly connected to the drive shaft 124 of the lower mirror cooling steel roller.

[0029] It is worth further explaining that when the drive motor starts, it can drive the upper mirror cooling steel roller drive shaft 132 and the lower mirror cooling steel roller drive shaft 124 to rotate respectively. At this time, the upper mirror cooling steel roller drive shaft 132 and the lower mirror cooling steel roller drive shaft 124 on one side can drive the mirror cooling steel roller 110 to rotate, and the lower mirror cooling steel roller drive shaft 124 on the other side drives the rubber pressure roller 111 to rotate.

[0030] Furthermore, each of the main columns 117 on one side is provided with an outwardly opening lifting guide groove 118. The lifting guide groove 118 is provided with a lifting drive rod 102 that can be lifted and moved. The lifting drive rod 102 passes through the main support beam 103 and extends upward to be fixedly connected to the lower end face of the upper roller system mounting beam 109.

[0031] It should be further explained that the lifting drive rod 102 is driven by a lifting device to move up and down along the lifting guide groove 118 within the main column 117. At the same time, the lifting drive rod 102 is limited by the main support beam 103, so that the lifting drive rod 102 can achieve a stable lifting and lowering movement effect.

[0032] Furthermore, two upright bases 105 are fixedly installed on the top of the support extension plates 104 on both sides respectively. The upright bases 105 on both sides are symmetrically arranged. An unwinding system bracket 106 is fixedly installed on the top of each upright base 105 on both sides to provide support. The four unwinding system brackets 106 are arranged in pairs, and a laser film unwinding roller 123 is rotatably installed between each pair. A traction winding roller 107 is fixedly installed on the outer end face of the laser film unwinding roller 123 on both sides. A laser film unwinding motor 114 is installed at one end of the unwinding system bracket 106 on one side. The laser film unwinding motor 114 is poweredly connected to one end of the laser film unwinding roller 123.

[0033] It should be further explained that when the laser film unwinding motor 114 starts, it can drive the laser film unwinding roller 123 to rotate via a power connection. When the laser film unwinding roller 123 rotates, it can drive the traction winding roller 107 to rotate. The outer end of the traction winding roller 107 on one side is used to wind the laser film for unwinding.

[0034] Furthermore, a laser film 112 is wound around the outer end face of the traction winding roller 107 on one side. One end of the laser film 112 passes through the mirror cooling steel roller 110 and the rubber pressure roller 111, and is output outward through the traction winding roller 107.

[0035] Furthermore, two vertical paper support columns 115 are fixedly provided on one side of the top of the frame base 101 on both sides. The paper support columns 115 are located between the main column 117 and the unwinding system bracket 106 on one side. A paper unwinding roller 127 is rotatably provided between the paper support columns 115 on both sides. A paper jamming roller drive motor 128 is installed at one end of the paper support column 115 on one side. The paper jamming roller drive motor 128 is poweredly connected to the paper unwinding roller 127.

[0036] Furthermore, a paper roll 116 is fixedly provided on the outer end face of the paper unwinding roller 127, and a roll of white cardboard 113 is wound around the outer end face of the paper roll 116. One end of the roll of white cardboard 113 extends outward between the rubber pressure roller 111 and the mirror cooling steel roller 110.

[0037] It should be further explained that when the laser film 112 and the roll of white cardboard 113 pass between the mirror cooling steel roller 110 and the rubber pressure roller 111, they are pressed and bonded together by the mirror cooling steel roller 110 and the rubber pressure roller 111. Then, the bonded film is rotated by the two mirror cooling steel rollers 110 on the other side, which further promotes the bonding of the film and paper. After that, it is output outward and continuously output outward by the traction winding roller 107, which facilitates the subsequent drying process.

[0038] It is worth further explaining that the mirror cooling steel roller 110 contains a cooling system for temperature regulation of the mirror cooling steel roller 110.

[0039] Furthermore, a coating system base 122 is fixedly provided on the top of the frame base 101 on both sides. The coating system base 122 on both sides is located between the main column 117 and the paper support column 115. A coating system bracket 121 is fixedly provided on the top of the coating system base 122 to provide support.

[0040] Furthermore, an angle adjustment shaft 129 is rotatably provided between the coating system supports 121 on both sides. A crossbeam-type glue spraying frame 130 is fixedly provided on the outer end face of the angle adjustment shaft 129. Several glue nozzles 131 are installed on the top of the crossbeam-type glue spraying frame 130. The crossbeam-type glue spraying frame 130 is located at the intersection of the coating system base 122 and the roll of white cardboard 113.

[0041] Furthermore, a back pressure roller drive motor 133 is installed on one side of the coating system bracket 121. The back pressure roller drive motor 133 is poweredly connected to the angle adjustment shaft 129. A hot melt adhesive delivery pipe 126 extending outward is connected to one side of the beam-type glue spraying frame 130. One end of the hot melt adhesive delivery pipe 126 is installed and connected to the hot melt pump device 120. A temperature regulating valve 125 is installed at the connection position between the hot melt adhesive delivery pipe 126 and the hot melt pump device 120.

[0042] It should be further explained that the glue nozzle 131 is connected to and outputs hot melt glue through the hot melt glue delivery pipe 126, and the temperature control valve 125 is used to control the temperature of the hot melt machine output in the hot melt glue delivery pipe 126 to achieve a suitable temperature.

[0043] It is worth further explaining that each drive element of this device is connected to and controlled by the control system.

[0044] A novel composite manufacturing process for laser transfer paper, the process flow of which is as follows:

[0045] S1. The equipment is initialized and set up. The operator starts each drive component through the control system, including the laser film unwinding motor 114, the cardboard roller drive motor 128, the back pressure roller drive motor 133, and the drive motors set in the upper roller system mounting beam 109 and the main support beam 103. At the same time, the hot melt pump device 120 starts to work, heating and melting the solid hot melt adhesive into a liquid state, and then transporting it to the beam-type glue spraying frame 130 through the hot melt adhesive delivery pipe 126.

[0046] S2. Subsequently, the temperature control valve 125 precisely controls the temperature of the hot melt adhesive, keeping it within a suitable coating range to ensure the fluidity and adhesion of the hot melt adhesive. The hot melt adhesive has a solid content of 100% and does not require water as a carrier, thus fundamentally avoiding the problems of paper fibers absorbing water and swelling and losing water and shrinking.

[0047] S3. During the unwinding stage, the laser film unwinding motor 114 drives the laser film unwinding roller 123 to rotate, so that the laser film 112 wound around the outer end of the traction winding roller 107 is continuously unwound. The laser film 112 has a pre-made laser transfer layer, which has a smooth surface and optical effect. At the same time, the cardboard roller drive motor 128 drives the paper unwinding roller 127 to rotate, which drives the roll of white cardboard 113 on the cardboard roll 116 to be unwound.

[0048] The roll of white cardboard 113 serves as the base paper. Its material is usually white cardboard or similar packaging paper, which has high flatness and strength. The laser film 112 and the roll of white cardboard 113 are guided by guide rollers and converge in the pressing area between the mirror cooling steel roller 110 and the rubber pressure roller 111.

[0049] S4. During the coating stage, the back pressure roller drive motor 133 drives the angle adjustment shaft 129 to rotate, thereby adjusting the angle of the beam-type glue sprayer 130 so that its glue nozzle 131 is aligned with the coating surface of the roll white cardboard 113. The multiple glue nozzles 131 on the beam-type glue sprayer 130 are evenly distributed to coat the surface of the roll white cardboard 113 with hot melt adhesive.

[0050] The coating amount is then precisely controlled within the range of 4-7 grams per square meter by the flow control of the hot melt pump device 120. Since the hot melt adhesive is a 100% solid content adhesive that transitions from solid to liquid, it begins to cool and cure immediately after coating without the need for water. This avoids the problems of paper fibers absorbing water and subsequent drying shrinkage caused by traditional water-based adhesives. A thin and uniform adhesive layer is formed on the surface of the coated roll of white cardboard 113, which has the function of filling the micro-depressions on the paper surface and helps to improve the mirror effect of the final product.

[0051] S5. During the pressing stage, the roll of white cardboard 113 coated with hot melt adhesive and the laser film 112 enter the pressing area between the mirror cooling steel roller 110 and the rubber pressure roller 111. At this time, the upper roller system mounting beam 109 can be precisely raised and lowered along the lifting guide groove 118 by adjusting the lifting drive rod 102, thereby controlling the gap pressure between the upper mirror cooling steel roller drive shaft 132 and the lower mirror cooling steel roller drive shaft 124.

[0052] The lifting device drives the lifting drive rod 102 to move, which in turn drives the telescopic support rod 108 between the upper roller system mounting beam 109 and the main support crossbeam 103 to work together to ensure a uniform distribution of the pressing force. The mirror cooling steel roller 110 and the rubber pressure roller 111 rotate in opposite directions under the drive of the drive motor, applying linear pressure to the laser film 112 and the roll of white cardboard 113.

[0053] S5.1 Subsequently, the elastic surface of the rubber pressure roller 111 provides a flexible pressing contact to avoid damage to the paper, while the high-gloss surface of the mirror-cooled steel roller 110 not only promotes pressing but also rapidly cools and solidifies the hot melt adhesive through the internal cooling system, so that the adhesive layer achieves initial solidification at the moment of pressing and forms a strong bond.

[0054] S5.2 After pressing, the composite paper then enters the second pressing zone, that is, between the two mirror cooling steel rollers 110 on the other side. The two mirror cooling steel rollers 110 rotate synchronously under the drive motor to perform secondary pressing and cooling on the composite paper, further strengthening the film-paper bonding force and improving the surface smoothness. Due to the rapid curing characteristics of hot melt adhesive, the composite paper immediately forms a stable structure after pressing, without the need for subsequent drying steps, thus significantly saving energy consumption.

[0055] S6. In the output stage, the composite paper is continuously pulled by the traction winding roller 107 and output from the end of the equipment. The traction winding roller 107 is indirectly driven by the laser film unwinding motor 114 to maintain a stable linear speed and ensure production continuity. The output composite paper can be directly wound or subjected to subsequent slitting to form the final laser transfer paper product.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

At the same time, the cardboard roller drive motor (128) drives the paper unwinding roller (127) to rotate, which drives the roll of white cardboard (113) on the cardboard roll (116) to be unwound. Roll white cardboard (113) is used as the base paper. Its material is usually white cardboard or similar packaging paper, which has high flatness and strength. The laser film (112) and the roll white cardboard (113) are guided by guide rollers and converge in the pressing area between the mirror cooling steel roller (110) and the rubber pressure roller (111). S4. During the coating stage, the back pressure roller drive motor (133) drives the angle adjustment shaft (129) to rotate, thereby adjusting the angle of the beam-type glue sprayer (130) so that its glue nozzle (131) is aligned with the coating surface of the roll white cardboard (113). The multiple glue nozzles (131) on the beam-type glue sprayer (130) apply hot melt adhesive to the surface of the roll white cardboard (113) in a uniformly distributed manner. The coating amount is then precisely controlled within the range of 4-7 g / m² by the flow control of the hot melt pump device (120). Since the hot melt adhesive is a 100% solid content adhesive that transitions from solid to liquid, it begins to cool and solidify immediately after coating without the need for water. This avoids the problems of paper fibers absorbing water and subsequent drying shrinkage caused by traditional water-based adhesives. A thin and uniform adhesive layer is formed on the surface of the coated roll of white cardboard (113), which has the function of filling the micro-depressions on the paper surface and helps to improve the mirror effect of the final product. S5. During the pressing stage, the roll of white cardboard coated with hot melt adhesive (113) and the laser film (112) enter the pressing area between the mirror cooling steel roller (110) and the rubber pressure roller (111). At this time, the upper roller system mounting beam (109) can be precisely raised and lowered along the lifting guide groove (118) by adjusting the lifting drive rod (102), thereby controlling the gap pressure between the upper mirror cooling steel roller drive shaft (132) and the lower mirror cooling steel roller drive shaft (124). The lifting device drives the lifting drive rod (102) to move, which in turn drives the telescopic support rod (108) between the upper roller system mounting beam (109) and the main support crossbeam (103) to work together to ensure the uniform distribution of the pressing force. The mirror cooling steel roller (110) and the rubber pressure roller (111) rotate in opposite directions under the drive of the drive motor, applying linear pressure to the laser film (112) and the roll of white cardboard (113). S5.1 Subsequently, the elastic surface of the rubber pressure roller (111) provides a flexible pressing contact to avoid paper damage, while the high-gloss surface of the mirror-cooled steel roller (110) not only promotes pressing but also rapidly cools and solidifies the hot melt adhesive through the internal cooling system, so that the adhesive layer achieves initial solidification at the moment of pressing and forms a strong bond. S5.2 After pressing, the composite paper then enters the second pressing zone, that is, between the two mirror cooling steel rollers (110) on the other side. The two mirror cooling steel rollers (110) rotate synchronously under the drive of the drive motor to press and cool the composite paper a second time, further strengthening the film-paper bonding force and improving the surface flatness. Due to the rapid curing characteristics of hot melt adhesive, the composite paper immediately forms a stable structure after pressing, without the need for subsequent drying steps, thus significantly saving energy. S6. In the output stage, the composite paper is continuously pulled by the traction winding roller (107) and output from the end of the equipment. The traction winding roller (107) is indirectly driven by the laser film unwinding motor (114) to maintain a stable linear speed and ensure production continuity. The output composite paper can be directly wound or subjected to subsequent slitting to form the final laser transfer paper product.
