Description

Technical Field

[0001] This utility model relates to the field of tinplate processing technology, specifically a flipping device that facilitates double-sided printing on tinplate. Background Technology

[0002] Tinplate is a thin sheet of steel plated with a layer of tin. This tin plating not only gives tinplate excellent corrosion resistance but also good sealing and weldability. Therefore, tinplate is often used to make various containers and packaging materials that require moisture-proof, corrosion-proof, or airtight properties, such as food cans, beverage cans, and cosmetic boxes.

[0003] The existing patent announcement number CN211390521U discloses a printing device for tinplate production, including an alcohol dampening tank, a base, a bottom plate, and a forward and reverse geared motor. A fixing block is fixedly connected to one side of the alcohol dampening tank, and a bushing is fixedly connected to one end of the fixing block. The rotating shaft of the forward and reverse geared motor is fixedly connected to a screw via a coupling. The screw with external threads is rotatably connected to the internal thread of the bushing. A slider is integrally provided at the bottom of the alcohol dampening tank, and a dovetail groove is formed on the upper part of the bottom plate. One end of the slider is slidably connected to the dovetail groove. This invention solves the gap problem between the alcohol dampening tank and the printing press by using a forward and reverse geared motor to drive the screw to rotate. The rotating screw thread drives the bushing to move linearly, thereby moving the fixedly connected alcohol dampening tank linearly.

[0004] While the above-mentioned technical solution allows printing on the surface of tinplate, printing on both sides requires manual flipping of the tinplate, increasing workload and increasing the risk of errors during the flipping process. Therefore, we provide a flipping device for facilitating double-sided printing on tinplate. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a flipping device for facilitating double-sided printing on tinplate includes a bracket 11. A first motor 12 is provided on one side of the top of the bracket 11. A flipping frame 13 is provided inside the bracket 11. A bearing 14 is provided on the side of the top of the bracket 11 away from the first motor 12. A first cylinder 15 is provided at both the top and bottom of the flipping frame 13. A mounting frame 16 is provided at the opposite end of each of the two first cylinders 15. A first conveyor belt 17 is provided between the two mounting frames 16. Support legs 19 are provided at both ends of the bottom of the bracket 11. A printing mechanism 2 is provided on both sides of the bracket 11.

[0024] In this embodiment, when the device is needed to print on both sides of tinplate, the tinplate can be placed on the second conveyor belt 24 of one of the printing mechanisms 2. The printing components on it can print on one side of the tinplate. After printing is completed, the second conveyor belt 24 can be started to transport the tinplate between the two sets of first conveyor belts 17. By simultaneously starting the two first cylinders 15, the two mounting frames 16 can be driven to move in opposite directions, and the two first conveyor belts 17 will gradually approach and press against each other, thereby pressing and limiting the tinplate between the two first conveyor belts 17. By starting the first motor 12, the flipping frame 13 can be driven to flip 180°, so the side that was originally printed will be flipped to the bottom, and the side that was not printed will be flipped to the top, waiting for subsequent printing. By starting the two first cylinders 15 again, the two first conveyor belts 17 can be separated, and the first conveyor belt 17 closer to the tinplate can be started to transfer the tinplate to another set of printing mechanisms 2 for printing.

[0025] like Figures 1-4 As shown, the printing mechanism 2 includes a support baffle 21, with support platforms 22 fixedly connected to both sides of the support baffle 21. A third motor 23 is fixedly installed at one end of one side of the support baffle 21. A second conveyor belt 24 is provided inside the support platform 22 and is driven by the third motor 23. A fixed frame 25 is fixedly connected to the top of the support platform 22, and a second cylinder 26 is fixedly installed on the top of the fixed frame 25. The output end of the bottom of the second cylinder 26 passes through the top of the fixed frame 25 and is fixedly connected to the top of the printing plate 27.

[0026] In this embodiment, when printing on the surface of tinplate, the tinplate can be placed on the second conveyor belt 24 and conveyed to the area below the printing plate 27 by the second conveyor belt 24. The printing plate 27 is then lowered by starting the second cylinder 26 to perform printing on the tinplate.

[0027] This utility model provides a flipping device for facilitating double-sided printing on tinplate, and its specific working principle is as follows:

[0028] When double-sided printing of tinplate is required, it can be placed on the second conveyor belt 24 of one of the printing mechanisms 2. The conveyor belt will send the tinplate to the bottom of the printing plate 27. Then, the second cylinder 26 will be activated to drive the printing plate 27 to press down and complete the single-sided printing. After completion, the second conveyor belt 24 will move the tinplate between the two sets of first conveyor belts 17. By activating the two first cylinders 15 simultaneously, the mounting frames 16 on both sides will move towards each other, so that the first conveyor belt 17 clamps the tinplate to fix its position. Then, the first motor 12 will be activated to drive the flipping frame 13 to rotate 180° so that the printed side is facing down and the unprinted side is facing up, in preparation for subsequent printing. The first cylinder 15 will be activated again to separate the conveyor belt and transport it to another printing mechanism 2 via the conveyor belt near the tinplate side for the other side printing operation.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
