[0002] Plastic bags are made of nitrocellulose as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their low cost, extremely light weight, large capacity and easy storage. Plastic bags can be seen everywhere in our lives and have also facilitated our lives. Existing plastic bags need to be packaged after production is completed, and different patterns need to be printed on the plastic bags using a printing device.

DETAILED DESCRIPTION
[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0024] Example: Figure 1-5 As shown, the utility model is a plastic bag printing device, including a support frame 1, one side of the support frame 1 is fixedly connected to a connecting plate 2, the upper end of the connecting plate 2 is fixedly connected to two cylinders 3, the top of the cylinder 3 is fixedly connected to a top plate 4, the bottom of the top plate 4 is fixedly installed with a driving motor 5, the output end of the driving motor 5 is transmission-connected to a ball screw 6, the outer peripheral thread of the ball screw 6 is connected to a threaded block 7, one side of the threaded block 7 is fixedly connected to a fixing plate 8, one side of the fixing plate 8 is fixedly welded with a U-shaped frame 9, the upper end of the U-shaped frame 9 is bolted to a power motor 10, and the output end of the power motor 10 passes through the U-shaped frame 9 and is transmission-connected to a roller 11.
[0025] Among them, the outer periphery of the roller 11 is connected to the rotating wheel 13 through the belt 12, and the rotating wheel 13 is movably connected to the U-shaped frame 9. The inside of the U-shaped frame 9 is fixedly connected to the round rod 14. By setting the belt 12, the slider 15 can be driven to move longitudinally and horizontally, so that the printing plate 24 can be moved flexibly and adjusted conveniently.
[0026] Among them, the outer periphery of the round rod 14 is slidably connected to the slider 15, and the inside of the slider 15 is fixedly connected to the belt 12. The lower end of the slider 15 is fixedly welded with a placement plate 16, and the bottom end of the placement plate 16 is fixedly installed with a servo motor 17. By setting the placement plate 16, the printing plate 24 can be driven to move horizontally. The operation is simple and convenient, which greatly improves the efficiency of the printing work.
[0027] The output end of the servo motor 17 is connected to a threaded rod 18, and a moving block 19 is threadedly connected to the outer periphery of the threaded rod 18. The moving block 19 is movably connected to the placement plate 16 through a slide rail 201. By providing the slide rail 201, the moving block 19 can move stably along the slide rail 201 to prevent deviation.
[0028] Among them, the lower end of the moving block 19 is fixedly connected to the mounting plate 20, and the surface of the mounting plate 20 is slidably connected to a number of slide bars 21, and the bottom of the slide bar 21 is fixedly connected to the anti-sticking plate 22, and the outer side of the slide bar 21 is sleeved with a spring 1 23, and the two ends of the spring 1 23 are respectively fixedly connected to the side walls of the mounting plate 20 and the anti-sticking plate 22. By setting the anti-sticking plate 22, when the printing plate 24 moves downward, since the anti-sticking plate 22 is set below the printing plate 24, the anti-sticking plate 22 will contact the plastic bag in advance and fix the plastic bag for printing. When the printing plate 24 moves upward, the anti-sticking plate 22 still has a fixing effect on the plastic bag under the elastic force of the spring 1 23, effectively preventing the printing plate 24 from sticking to the plastic bag, and will not affect the next printing work.
[0029] Among them, the printing plates 24 are slidably connected to the two sides of the lower end of the mounting plate 20, and sliding holes 25 are opened on both sides of the mounting plate 20. The sliding holes 25 are movably connected to the disassembly columns 26. One end of the disassembly columns 26 is fixedly connected to the limit plate 27. The outer side of the disassembly columns 26 is sleeved with a spring 28, and the two ends of the spring 28 are respectively fixedly connected to the inner wall of the mounting plate 20 and the side wall of the limit plate 27. By setting the disassembly columns 26, pulling the disassembly columns 26, the disassembly columns 26 are moved in the sliding holes 25, and then the printing plate can be disassembled, and the printing can be replaced in time. The operation is simple and convenient, which greatly improves the efficiency of the printing work.
[0030] Among them, a micro motor 29 is fixedly connected to one side of the support frame 1, and the output end of the micro motor 29 is connected to a roller through the support frame 1, and the periphery of the roller is connected to a transmission belt 30. The outer periphery of the support frame 1 is symmetrically fixedly connected to a connecting seat 31, and the interior of the connecting seat 31 is movably connected to a roller 32. By setting the roller 32, when wrinkles appear on the plastic bag, the wrinkles on the plastic bag are flattened by the roller 32, thereby enhancing the flattening effect of the plastic bag and improving the overall printing quality.
[0031] Working principle: When in use, turn on the micro motor 29, so that the micro motor 29 drives the roller to rotate, and then drives the conveyor belt 30 to rotate, and the plastic bag to be printed is placed on the conveyor belt 30, and passes through the roller 32. When wrinkles appear on the plastic bag, the wrinkles on the plastic bag are flattened by the roller 32, thereby enhancing the flattening effect of the plastic bag and improving the overall printing quality. Then turn on the drive motor 5, so that the drive motor 5 drives the ball screw 6 to move, so that the threaded block 7 drives the fixed plate 8 to move up and down, and start the power motor 10. The output end of the power motor 10 drives the roller 11, and drives the slider 15 to move longitudinally through the belt 12. Start the servo motor 17, and the output end of the servo motor 17 drives the threaded rod 18 to rotate, so that the moving block 19 moves horizontally. The printing plate 24 can be flexibly moved, easily adjusted, and operated simply and conveniently, which greatly improves the efficiency of the printing work. When the printing plate 24 moves downward to start printing, since the anti-sticking plate 22 is arranged below the printing plate 24, the anti-sticking plate 22 will contact the plastic bag in advance and fix the plastic bag for printing. After printing is completed, when the printing plate 24 moves upward, the anti-sticking plate 22 still has a fixing effect on the plastic bag under the elastic force of the spring 1 23, effectively preventing the printing plate 24 from sticking to the plastic bag, and will not affect the next printing work. When the printing plate 24 is disassembled, the disassembly column 26 is pulled to make the disassembly column 26 move in the slide hole 25, and then the printing plate 24 can be disassembled, and the printing can be replaced in time. The operation is simple and convenient, which greatly improves the efficiency of the printing work.
