Description

Technical Field

[0001] The invention relates to the technical field of printing machines, in particular to a printing machine capable of intermittent cold foil lamination and die cutting. Background Art

[0002] A printing press is a machine specially used for printing text and images. Its working principle is to make the text and images to be printed into a printing plate, and then install it on the printing press. Ink is applied to the places with text and images on the printing plate by humans or the printing machine, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed products as the printing plate. Cold perm is a major category of perm, also known as "chemical perm", which refers to a form of perm process that can be completed at room temperature by the reaction of chemical agents. The principle of cold perm is to maintain the fixed shape of the hair through chemical action. Lamination is a surface processing technology after printing, also known as post-printing lamination, post-printing mounting or post-printing film. Cold perm and lamination are key links in printing by printing presses.

[0003] Existing cold foil and laminating technologies are often designed to match full-rotary printing presses. Their workflow and rhythm are closely related to the high-speed, continuous operation mode of full-rotary printing presses. However, intermittent printing presses have a unique step-by-step working mode, that is, after completing a printing action within a working cycle, there will be a pause time to prepare for the next printing. This working mode is obviously mismatched with existing cold foil and laminating technologies. This mismatch makes it difficult for the cold foil and laminating processes to achieve precise synchronization with the printing action during intermittent printing, which in turn affects the quality and consistency of the finished product. In addition, in the application scenario of intermittent printing presses, the existing circular knife pressing technology is often not as fast and strong as the circular knife during the pressing process due to design limitations.

[0004] Therefore, in view of the problem that the above-mentioned existing cold foiling, laminating and circular knife technologies are difficult to perfectly match with intermittent printing machines and the circular knife pressing efficiency is low, a printing machine capable of intermittent cold foiling, laminating and die-cutting can be designed. Summary of the invention

[0005] In order to overcome the problem that the existing cold foil, lamination and circular knife technologies are difficult to perfectly match with intermittent printing machines, and the existing circular knife pressing efficiency is low.

[0006] The technical scheme of the present invention is as follows: a printing machine capable of intermittent cold stamping, laminating and die-cutting comprises a cold stamping mechanism, a laminating mechanism and a circular knife quick pressing mechanism, the cold stamping mechanism comprises a cold stamping frame, the lower end of the cold stamping frame is connected with a cold stamping machine base, the front end of the cold stamping frame is connected with a feeding air expansion shaft, the front end of the cold stamping frame is provided with a feeding traction device, the front end of the cold stamping frame is provided with a floating roller 1, the front end of the cold stamping frame is provided with a floating roller 2, the front end of the cold stamping frame is provided with a floating roller 3, the front end of the cold stamping frame is provided with a floating roller 4, the upper end of the cold stamping machine base is provided with a UV curing device, the upper end of the cold stamping machine base is provided with a slide rail, and the lower end of the slide rail is provided with a synchronous belt transmission The front end of the cold stamping machine frame is connected with a material receiving traction device, the front end of the cold stamping machine frame is connected with a material receiving air expansion shaft, the laminating mechanism includes a laminating frame, the upper end of the laminating frame is equipped with a feeding control box, the upper end of the laminating frame is equipped with a material receiving control box, the front end of the laminating frame is connected with a floating roller five, the front end of the laminating frame is connected with a floating roller six, the front end of the laminating frame is connected with a floating roller seven, the circular knife quick pressing mechanism includes a cutter upper plate, the upper end of the cutter upper plate is connected with a screw seat, the inner side of the screw seat is connected with a screw, the lower end of the screw is connected with a pressure roller seat, the lower end of the pressure roller seat is connected with a load-bearing bearing one, and the lower end of the load-bearing bearing one is provided with a magnetic suction roller.

[0007] Preferably, the cold stamping mechanism is precisely controlled by a servo motor to achieve the coordinated operation of the feeding traction device, the receiving traction device, the receiving air shaft and the synchronous belt drive assembly.

This high-precision synchronous control effectively avoids the hot stamping scratch problem that may be caused when the substrate is retracted, ensuring the consistency and stability of the hot stamping quality. The laminating mechanism adopts three servo motors to respectively control the feeding shaft, the material traction device and the receiving shaft, thereby achieving full automation control of the laminating material from feeding to receiving, and tension compensation is performed through the floating of the floating roller, and the tension state of the laminating material and the hot stamping material is monitored and adjusted in real time, ensuring that the material always remains flat and stable during the transportation and processing process, effectively avoiding problems such as material deviation or scratching, thereby ensuring the high quality and consistency of the printed product.

[0030] During cold stamping, the cold stamping mechanism controls the coordinated operation of the feeding traction device 2, the receiving traction device 25, the receiving air shaft 26 and the synchronous belt transmission assembly through four servo motors. The hot stamping material passes through the feeding traction device 2 from the feeding air shaft 1 in sequence → → paper roller 1 3 → floating roller 1 4 → paper roller 2 5 → floating roller 2 6 → paper roller 3 7 → paper roller 4 8 → paper roller 5 9 → paper roller 6 10 → synchronous belt transmission assembly. At this time, the rotation of the synchronous belt drive servo motor drives the synchronous wheel 12 and the synchronous wheel 2 13 to the laminating device 11 and the stripping device 11. Device 15 moves horizontally on the slide rail 16, and then synchronized with the intermittent printing action, and then the hot stamping material continues to pass through the paper roller seven 17 → paper roller eight 18 → paper roller nine 19 → paper roller ten 20 → floating roller three 21 → paper roller eleven 22 → floating roller four 23 → paper roller twelve 24 → material collection traction device 25 → material collection air shaft 26. At the same time, sensor one 27 and sensor two 28 respond quickly, and adjust the feeding speed in time to keep the material in a tensioned state, effectively avoiding the problem of material relaxation or excessive stretching, and finally completing the cold stamping operation.

[0031] During lamination, the laminating mechanism controls the feed shaft 34, the material traction device 38 and the receiving shaft 37 respectively through three servo motors, and then the laminating material is fixed on the feed shaft 34, and the peeled base paper is fixed on the receiving shaft 37. Then the material passes through the material traction device 38 → paper feeding roller thirteen 39 → floating roller five 43 → paper feeding roller fourteen 40 → floating roller six 44 → paper feeding roller fifteen 41 → paper feeding roller sixteen 46 → floating roller seven 45 → laminating device two 47 in sequence. At the same time, sensor three 42 responds quickly and adjusts the feeding speed in time to keep the material in a tensioned state, effectively avoiding the problem of material relaxation or excessive stretching, so as to carry out the laminating operation.

[0032] When the circular knife quick pressing mechanism is working, the screw 52 can be moved up and down on the screw seat 50 by rotating the pressure regulating hand wheel 53 to adjust the position between the load-bearing bearing 1 55 on the pressure roller seat 54 connected below the screw 52 and the magnetic roller 57. After adjusting to the appropriate position, the locking nut 51 is rotated to fix it. Then, the pressing handle 59 is radially fixed to the eccentric shaft 61. By pulling the pressing handle 59, the load-bearing bearing 2 64 on the eccentric shaft 61 can be driven to press downward, so that the load-bearing bearing 1 55 on the pressure roller seat 54 presses the magnetic roller 57 downward to realize the circular knife pressing operation.

[0033] Through the above steps, a floating roller is set between the paper feeding rollers, and the floating of the floating roller is used for tension compensation, so that the tension state of the laminating material and the hot stamping material can be monitored and adjusted in real time. By accurately controlling the synchronization between the cold stamping / laminating feeding interval and the printing interval, it is perfectly adapted to the intermittent printing machine, which solves the limitation that the traditional cold stamping / laminating solution is only applicable to full-rotary printing machines. At the same time, by modifying the existing circular knife solution, a rapid pressing mechanism is added, which effectively improves the work efficiency and production quality, so as to solve the problem that the existing cold stamping, laminating and circular knife technologies are difficult to achieve perfect matching with intermittent printing machines, and the existing circular knife pressing efficiency is low.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
