[0037] Please refer to the following: Figure 1 and Figure 2 The present application provides a magnetic variable ink composite printing machine according to an embodiment. The magnetic variable ink composite printing machine includes a printing assembly 100, a base 101, an ink tray 102, a roller assembly, and an ink processing assembly. Wherein:

[0038] The printing assembly 100 is used to print a target pattern on the target substrate 201; the base 101 is spaced apart from the printing assembly 100; the ink tray 102 is connected to the base 101 and forms an opening at the top; the roller assembly includes a gravure roller 103 that is horizontally placed on top of the ink tray 102 and can take ink from the ink tray 102, and also includes a substrate roller 104 that is movably mounted on the base 101 and parallel to the gravure roller 103. The substrate roller 104 cooperates with the gravure roller 103 to form a gap for the target substrate 201 to pass through, and the substrate roller 104 can move closer to or away from the gravure roller 103; the ink processing assembly includes a magnetic roller 105 that can guide the change of magneto-modified ink and a curing device 106 for curing the magneto-modified ink. The magnetic roller 105 is parallel to the gravure roller 103 and the curing device 106 are distributed sequentially and spaced apart along the conveying direction of the target substrate 201.

[0039] It is understood that the printing component 100 described in this embodiment is a commonly used structure in the art. Specifically, it may include an unwinding shaft for unwinding the target substrate 201, a correction mechanism for correction, and a printing color group 123 for printing images, etc., which will not be described in detail here. In addition, the magnetic roller 105 and the curing device 106 can also adopt commonly used structures in the art. For example, the magnetic roller 105 can be a magnetic roller with permanent magnets arranged in a set combination, or it can be an electromagnetic roller 105 structure with multiple coils arranged in a set rule, as long as it can guide the magnetic ink to achieve the purpose of dynamic color change of the pattern or information development. The curing device 106 can be a UV curing machine commonly used in the art, which will not be described in detail here.

[0040] According to the structure provided in this embodiment, in the magnetic variable ink composite printing machine provided in this embodiment, since the gravure roller 103 horizontally placed on top of the ink tray 102 can adsorb magnetic variable ink from the ink tray 102, and the printing roller 104 movably mounted on the base 101 can approach or move away from the gravure roller 103, when the printing roller 104 moves away from the gravure roller 103, the target substrate 201 can smoothly pass through the gap between the printing roller 104 and the gravure roller 103 to complete the feeding process, which is convenient for feeding during the first printing; when the printing roller 104 approaches the gravure roller 103, the target substrate 201 passes through the gap between the printing roller 104 and the gravure roller 103 and can be bonded to the gravure plate of the gravure roller 103 with the magnetic variable ink of the set pattern. Then, the pressure roller 107 laminates a layer of target film 202 on the printing surface of the target substrate 201 to magnetic variable ink. The ink image information is protected (see below), and then enters the heating roller 120 for heating and drying to ensure tight adhesion between the target film material 202 and the target substrate 201. Thus, after the magnetic variable ink passes sequentially through the magnetic roller 105 (which guides the ink's changes) and the curing device 106 (which solidifies the ink), a magnetic variable ink printing process is achieved, where the ink adheres to the target substrate 201 and dynamically changes color or develops information according to the magnetic field set on the magnetic roller 105. When printing magnetic variable ink is not required, simply raise the printing roller 104 away from the gravure roller 103. In this case, the magnetic variable ink composite printing machine can perform conventional printing and lamination processes. Simultaneously, when the target substrate 201 with printed images is directly output from the printing color group 123 to other subsequent functional components such as rewinding, it can also be used for conventional printing. Therefore, the magnetic variable ink composite printing machine provided in this embodiment can be conveniently used for different printing processes, far superior to existing technologies.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2The roller assembly also includes a pressing roller 107 and a waste roll 108, which are parallel to the printing roller 104. The pressing roller 107 is movably mounted on the base 101 and can be close to or away from the printing roller 104. The pressing roller 107 is used to laminate the target film material 202 onto the target substrate 201, which has been printed with magnetic variable ink graphic information by the gravure printing roller 103. The waste roll 108 is located on the same side of the printing roller 104 as the pressing roller 107 and is used to wind up the release paper peeled off from the target film material 202. According to the structure provided in this embodiment, the gap between the pressing roller 107 and the printing roller 104 can be used for the target film material 202 to pass through, while the waste roll 108 connected to the base 101 can wind up the release paper peeled off from the target film material 202. When the target substrate 201 and the target film 202 pass through the gap between the pressing roller 107 and the printing roller 104, the pressing roller 107, which is close to the printing roller 104, can bond the target film 202 to the target substrate 201. This achieves the technical effect of coating the target substrate 201, and also helps to further enrich the function of the magnetic variable ink composite printing machine in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The magnetic variable ink composite printing machine also includes a drive mechanism; the drive mechanism includes a lifting cylinder 109 mounted on a base 101, a floating seat 110 connected to the power end of the lifting cylinder 109, and a pressing cylinder 111 mounted on the floating seat 110; the printing roller 104 is rotatably mounted on the floating seat 110, and the pressing roller 107 is connected to the power end of the pressing cylinder 111. According to the structure provided in this embodiment, the lifting cylinder 109 can drive the printing roller 104 to move closer to or further away from the gravure roller 103, and can also drive the pressing cylinder 111 connected to the floating seat 110 to move. In this way, the pressing roller 107 connected to the power end of the pressing cylinder 111 can be driven by the lifting cylinder 109 and the pressing cylinder 111, thereby significantly improving the adjustment flexibility of the pressing roller 107.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The drive mechanism also includes a linear guide 112 extending radially along the printing roller 104; the linear guide 112 is connected to the base 101 and slidably connected to the floating seat 110. According to the structure provided in this embodiment, the linear guide 112 connected to the base 101 can effectively improve the movement stability of the floating seat 110, which can significantly improve the movement stability of the pressing roller 107.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2The magnetic variable ink composite printing machine also includes a drive mechanism and a doctoring mechanism; the doctoring mechanism includes a gear 113 connected to the base 101 and a rack 114 that is driven by the gear 113, and a doctor blade 115 connected to the rack 114; the moving direction of the rack 114 is parallel to the linear guide 112, the gravure roller 103 is arranged on the moving path of the doctor blade 115 and the doctor blade 115 can be driven by the rack 114 to approach or move away from the gravure roller 103. According to the structure provided in this embodiment, since the gravure roller 103 is arranged on the moving path of the doctor blade 115, when the gear 113 drives the rack 114 to move, it can drive the doctor blade 115 to move closer to or further away from the gravure roller 103. In this way, on the one hand, the doctor blade 115 can form a tight fit with the gravure roller 103 to scrape off excess magnetic ink from the gravure plate of the gravure roller 103 to ensure clear printed images. On the other hand, when it is necessary to change the plate or clean the gravure plate, the doctor blade 115 can be completely removed from the surface of the gravure plate of the gravure roller 103, thereby facilitating plate change or cleaning. This is beneficial to enable the magnetic ink composite printing machine in this embodiment to achieve better printing accuracy of magnetic ink and target substrate 201.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The ink scraping mechanism also includes a swing cylinder 116, a lifting seat 117, and a swing seat 118. The swing cylinder 116 and the lifting seat 117 are connected side-by-side to the rack 114 in a direction perpendicular to the rack 114. The swing seat 118 is hinged to the power ends of the lifting seat 117 and the swing cylinder 116, and all rotational axes of the swing seat 118 are parallel. The scraper 115 is connected to the swing seat 118. According to the structure provided in this embodiment, since the swing seat 118 is hinged to the lifting seat 117 and the power end of the swing cylinder 116, when the swing cylinder 116 extends or retracts, it can drive the swing arm to swing. Thus, the scraper 115 connected to the swing arm can also swing with the swing arm. In this way, the scraper 115 can form a more appropriate pressure contact with the gravure roller 103, ensuring the effect of scraping off excess magnetic ink. This is beneficial to ensuring the printing accuracy and clarity of magnetic ink on the target substrate 201 by the magnetic ink composite printing machine in this embodiment.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2The magnetic variable ink composite printing machine also includes a heating base 119 and at least two heating rollers 120 connected to the heating base 119 for heating; the heating base 119 and the base 101 are arranged side by side at intervals, and the heating rollers 120 are parallel to the gravure rollers 103. According to the structure provided in this embodiment, the at least two heating rollers 120 provided on the heating base 119 can be used to heat the front and back sides of the target substrate 201 respectively, so that the target film 202 can form a better bonding effect with the target substrate 201. In specific implementation, setting multiple heating rollers 120 can achieve better heating effect, so that the front and back sides of the target substrate 201 are heated and deformed uniformly. For ease of explanation, this embodiment uses four heating rollers 120 as an example.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The magnetic variable ink composite printing machine also includes a frame 121; the frame 121 forms a worktable 122, with the printing assembly 100 and the base 101 disposed on opposite sides of the worktable 122, and the heating seat 119 disposed on the same side of the worktable 122 as the base 101. According to the structure provided in this embodiment, arranging the printing assembly 100 and the base 101 on opposite sides of the worktable 122 achieves better space utilization, thus contributing to a more integrated design for the magnetic variable ink composite printing machine in this embodiment.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The printing assembly 100 includes a plurality of printing ink groups 123 arranged sequentially at intervals along a straight line. The heating seat 119 and the base 101 are both slidably connected to the worktable 122, and the moving direction of the heating seat 119 and the base 101 is parallel to the arrangement direction of the printing ink groups 123. According to the structure provided in this embodiment, the heating seat 119 and the base 101, slidably connected to the worktable 122, can better adapt to the position of the printing ink groups 123, which helps the magnetic variable ink composite printing machine provided in this embodiment to achieve a more flexible printing effect.
