Description

Technical Field

[0001] This invention belongs to the field of digital printing and hot stamping, and particularly relates to a 3D gold foil transfer machine. Background Technology

[0002] The personalized consumer goods market continues to develop, with a significant increase in demand for printed materials featuring 3D visuals and metallic textures. Products in packaging, cultural and creative products, greeting cards, and high-end brochures that integrate 3D graphics with gold foil hot stamping have received positive market feedback due to their unique tactile feel and luster. However, the existing traditional production process is a split operation, first using a 3D printer or UV flatbed printer to print 3D graphics on the paper surface, and then transferring the printed paper to a separate gold foil hot stamping device for precise hot stamping.

[0003] The separate production method suffers from two main problems. First, the dispersed processes require multiple material handling and repositioning, and the errors from these handling and repositioning directly affect the registration accuracy of hot stamping and printing, resulting in a low yield rate. Second, printing and hot stamping cannot be performed simultaneously, leading to low equipment utilization and failing to meet the efficiency requirements of mass production. While existing combined equipment attempts to integrate these two functions into a single machine, it typically operates as a single-station sequential process with long cycle times for printing and hot stamping. Loading and unloading are primarily manual, resulting in low automation. Furthermore, the lack of a stable transfer mechanism when handling large or soft paper can easily cause paper shifting or warping during transport, affecting processing quality. In addition, the coordination and precision of temperature and pressure control in the hot stamping process with that in the printing process are insufficient.

[0004] Based on the above existing technologies, there is a need for processing equipment that can efficiently integrate 3D printing and gold foil hot stamping, and achieve registration and automated continuous operation. Therefore, a 3D gold foil transfer machine is proposed. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, please refer to Figures 1 to 4This invention provides a 3D gold foil transfer machine, including a frame body 1. The bottom of the frame body 1 is equipped with frame feet 2 for connecting to the ground and adjusting its level. An electrical control cabinet 3 and a pneumatic control cabinet 4 are housed inside the frame body 1, respectively for installing the electrical control system and the pneumatic control system. A heat dissipation system is also installed inside the frame body 1, including a cooling fan and a temperature sensor. The cooling fan is installed near the electrical control cabinet 3 and the pneumatic control cabinet 4. The temperature sensor monitors the internal temperature in real time, and automatically activates the cooling fan for forced heat dissipation when the temperature exceeds a set threshold. Simultaneously, the side walls of the frame body 1 are equipped with heat dissipation plates made of perforated aluminum plates, which conduct heat to the outside, forming a convection heat dissipation channel with the cooling fan, effectively reducing the operating temperature and ensuring long-term stable operation of the electrical and pneumatic components.

[0045] A manual transfer cart 5 is located at the front of the frame 1 to carry the paper 6 to be processed. A conveying mechanism 7 is located at the front end of the frame 1, which connects to the manual transfer cart 5 to pick up and transfer the paper 6. A transfer mechanism 8 is located in the middle of the frame 1, which includes a first transfer platform 83 and a second transfer platform 84 that can move alternately. A 3D printing mechanism 9 and a gold foil pressing mechanism 10 are located at the rear end of the frame 1, both of which are fixed to the frame 1 with bolts. A receiving platform 11 is located at the rear of the frame 1 to collect the finished paper.

[0046] Please see Figure 5 The manual transfer cart 5 includes a tray 51. Guide wheels 52 are provided on the front bottom side of the tray 51, and casters 53 are provided on the rear bottom side. The casters 53 have a braking function for easy movement and positioning. A push handle 54 is provided on the rear top side of the tray 51, and the paper 6 is placed at the center of the top of the tray 51. Guide plates 55 are provided at the four corners of the paper 6 on the upper surface of the tray 51. The guide plates 55 are L-shaped or right-angled limiting blocks used to precisely limit the position of the paper 6, ensuring that the paper is in a consistent position each time it is loaded. Preferably, the surface of the tray 51 is provided with anti-slip textures or low-pressure suction holes to prevent the paper from slipping during the feeding process.

[0047] Please see Figure 6The conveying mechanism 7 includes a fixed frame 71 with fixed frame feet 72 at its bottom for support and leveling. The fixed frame 71 is reinforced to the frame body 1 via corner brackets made of right-angle castings. Bolts are used to lock the fixed frame 71 and the frame body 1 together, improving overall rigidity. A linear conveying guide rail 73 is provided on the top of the fixed frame 71 along the X-axis. A conveying belt 74 and a Z-axis power unit 75 are mounted on the linear conveying guide rail 73. The Z-axis power unit 75 can move horizontally along the linear conveying guide rail 73. A pulley 710 is provided at the front end of the conveying belt 74, and a conveying motor 711 is connected to the rear end of the conveying belt 74. The conveying motor 711 drives the conveying belt 74, which in turn drives the drive pulley 710, enabling the Z-axis power unit 75 to move horizontally along the linear conveying guide rail 73. The Z-axis power unit 75 is equipped with a Z-axis lifting mechanism 76. A suction rod mounting plate 78 is connected to the bottom of the Z-axis lifting mechanism 76 via a support rod 77. Multiple vacuum suction components 79 are mounted on the bottom surface of the suction rod mounting plate 78. Each vacuum suction component 79 is a silicone suction cup, independently controlled, and adaptable to different paper sizes. A linear displacement sensor is installed within the Z-axis lifting mechanism 76 to achieve closed-loop control of the Z-axis height, enabling height-finding operations and preventing damage to the paper. The vacuum suction components 79 are connected to a vacuum generator, which is installed inside the pneumatic control cabinet 4 and controlled by a solenoid valve to achieve rapid suction and release.

[0048] Please see Figure 7 and Figure 8 The transfer mechanism 8 also includes a mounting plate 81 and a lifting column 82. The mounting plate 81 is fixed to the middle of the frame 1, and the lifting column 82 is located on top of the mounting plate 81, with an adjustable height. The first transfer platform 83 and the second transfer platform 84 are located on top of the lifting column 82 and are arranged in a front-to-back pattern on the top of the frame 1. The first transfer platform 83 and the second transfer platform 84 are connected by the same transmission belt and move alternately along the cam slide 85. The cam slide 85 includes smoothly transitioning trough sections and peak sections. When the two platforms move towards each other to an intersecting position, the trough section is used to lower one of the platforms to avoid mutual interference. Each transfer platform surface is provided with multiple vacuum adsorption holes, connected to a negative pressure chamber below, and the adsorption and release states are switched by a solenoid valve. A drag chain is provided on the outside of the mounting plate 81. The drag chain houses the vacuum adsorption pipelines, sensor signal lines, and power lines of the first transfer platform 83 and the second transfer platform 84. The drag chain bends or extends as the platform moves, effectively preventing cable tangling or wear.

[0049] Please see Figure 7 and Figure 8The 3D printing mechanism 9 is positioned above the transport mechanism 7 and includes an X-axis power system 91, an X-axis linear guide rail 92, and a Y-axis moving device 93. The X-axis power system 91 drives the X-axis transmission belt 96 on the X-axis linear guide rail 92 via a transmission shaft 94 and a coupling 95. The Y-axis moving device 93 is mounted on the X-axis linear guide rail 92 and can move along the X-axis. The Y-axis moving device 93 includes a Y-axis linear guide rail 931, with the Y-axis power system 932 located at one end and an ink cartridge device 97 located on top of the Y-axis power system 932. A Y-axis transmission belt 933 is mounted on the Y-axis linear guide rail 931, and a belt cover 934 is located on the outside of the Y-axis transmission belt 933. The other end of the Y-axis transmission belt 933 is connected to a print head 98, which has an ink extraction device 99. The print head 98 is a piezoelectric printhead that supports UV-curable ink and is surrounded by UV-LED curing lamps, enabling simultaneous printing and curing. The X-axis power system 91 and the X-axis linear guide 92 are equipped with protective covers 910 to prevent dust and provide protection. A waste ink collection box can be installed below the printhead 98 for easy maintenance.

[0050] Please see Figure 9 The gold foil pressing mechanism 10 includes a vertically placed base 101. A take-up mechanism 102 and an unwinding mechanism 103 are located in the middle of the base 101, and a transition support rod 104 is located at the bottom of the take-up mechanism 102 and the unwinding mechanism 103. A height adjustment device 105 is located at the top of the base 101, and a sliding block 106 is slidably mounted in a slot on the front side of the base 101. The top of the sliding block 106 is connected to the height adjustment device 105, allowing adjustment of the initial height of the sliding block 106. A pneumatic actuation system 107 is installed inside the sliding block 106. The pneumatic actuation system 107 is connected to an execution block 109 via a connecting rod 108. The connecting rod 108 and the execution block 109 are hinged together by a rotating shaft, allowing the execution block 109 to swing at a small angle around the rotating shaft under the drive of the pneumatic actuation system 107. This adapts to minor unevenness on the paper surface, ensuring uniform contact between the hot pressing mechanism 110 and the paper, and improving the hot stamping quality. A hot-pressing mechanism 110 is located at the bottom of the actuator 109. The hot-pressing mechanism 110 includes a heating plate and a high-temperature resistant, non-stick coating. It is equipped with temperature and pressure sensors to achieve closed-loop temperature and pressure control. The transition support rod 104 is a floating roller used to adjust the speed of the take-up motor and maintain constant tension of the gold foil during hot stamping. A control box for controlling the pneumatic actuator system 107 is located on one side of the base 101. The control box integrates a solenoid valve group, a pressure regulating valve, and an air distributor, which is connected to the air control cabinet 4 to control the pressing speed, pressure, and holding time of the pneumatic actuator system 107.

[0051] In addition, protective doors are installed around the frame 1, which automatically stop the machine if personnel accidentally enter the work area. Mechanical limit blocks and photoelectric limit switches are installed at both ends of each motion axis to prevent overtravel. A touch screen control panel is installed on the front of the frame 1 for displaying equipment status, setting process parameters such as temperature, pressure, speed, and printing mode, manual debugging, and fault alarm display. The entire machine is centrally controlled by a PLC or industrial computer, and all cylinders, motors, and sensors are connected to the control system.

[0052] The receiving platform 11 is detachable and equipped with a full-material alarm sensor and a counting sensor for easy production statistics and timely cleaning. Preferably, the receiving platform 11 includes a rotating belt and a receiving box. The rotating belt is driven by a motor and is used to smoothly transport the finished paper after pressing into the receiving box. A cable chain is provided on the outside of the mounting plate 81, and the cable chain houses the vacuum adsorption pipelines, sensor signal lines, and power lines of the first transfer platform 83 and the second transfer platform 84. The cable chain bends or extends as the platform moves, effectively preventing cable tangling or wear.

[0053] Example 2: The present invention also provides a control method based on the above-mentioned 3D gold foil transfer machine, comprising the following steps:

[0054] S1: Loading Positioning

[0055] The paper 6 to be processed is placed manually on the pallet 51 of the manual transfer cart 5, and is limited by the guide plates 55 at the four corners. Then the manual transfer cart 5 is pushed, and the guide wheels 52 and casters 53 are used to move it to the designated position below the conveying mechanism 7, and the brakes of the casters 53 are locked.

[0056] S2: Adsorption, paper picking, and transfer

[0057] The equipment is started, and the Z-axis power unit 75 of the conveying mechanism 7 drives the Z-axis lifting mechanism 76 to descend, bringing the vacuum suction component 79 into contact with the surface of the paper 6. The Z-axis lifting mechanism 76 performs Z-axis height seeking according to a preset program using a linear displacement sensor. After the suction cup makes good contact with the paper, the vacuum generator is activated, and the vacuum suction component 79 adsorbs the paper 6. Then, the Z-axis lifting mechanism 76 rises to the waiting position, moves along the X-axis to above the first transfer platform 83, descends again, and places the paper 6 on the first transfer platform 83. The vacuum suction system of the first transfer platform 83 is activated, adsorbing and fixing the paper 6. The vacuum suction component 79 of the conveying mechanism 7 releases and returns to its original position.

[0058] S3: 3D Printing

[0059] The X-axis power system 91 and Y-axis power system 932 of the 3D printing mechanism 9 work together to move the print head 98 above the first transfer platform 83. The vision system uses an industrial camera to identify the paper position or printing start point and performs automatic alignment compensation. According to the preset 3D graphic program, the print head 98 sprays UV-curable ink onto the surface of the paper 6, while a UV-LED curing lamp simultaneously cures the ink, forming a three-dimensional graphic. After printing is complete, the print head 98 moves out of the working area.

[0060] S4: Alternating transfer

[0061] After printing is completed, the first transfer platform 83 and the second transfer platform 84 are driven by the same transmission belt and move towards each other along the cam slide 85. During the movement, the trough section of the cam slide 85 causes the two platforms to be staggered vertically at their intersection positions to avoid interference. Finally, the first transfer platform 83 moves to below the gold foil pressing mechanism 10, and the second transfer platform 84 moves to below the 3D printing mechanism 9, completing the station alternation.

[0062] S5: Gold Foil Pressing

[0063] After receiving the positioning signal, the temperature control system heats the hot pressing mechanism 110 to a set temperature, which is 120-180℃, depending on the gold foil material. The pneumatic actuator 107 drives the actuator block 109 to descend via the connecting rod 108, and the hot pressing mechanism 110 presses the gold foil onto the printing area of ​​the paper 6, holding it for a set time, such as 1-3 seconds. Simultaneously, the take-up mechanism 102 and the unwinding mechanism 103 work together to achieve automatic gold foil feeding and waste recycling. After pressing is complete, the hot pressing mechanism 110 rises.

[0064] S6: Material unloading and collection

[0065] After pressing is completed, depending on the current workstation, either the first transfer platform 83 or the second transfer platform 84 releases the vacuum adsorption, conveying the finished paper to the receiving box of the receiving platform 11. The counting sensor in the receiving box records the output and alarms when the box is full. At this time, the other transfer platform has completed printing and can immediately enter the pressing process, realizing parallel operation of the two workstations.

[0066] It should be noted that the design of the trough section of the cam slide in step S4 allows the first and second transfer platforms to move in a staggered manner during movement, avoiding mutual interference. In step S5, before the gold foil pressing mechanism performs the pressing action, the temperature control system preheats the hot pressing mechanism to the set temperature, and achieves closed-loop control through temperature and pressure sensors, ensuring stable hot stamping quality.
