Description
Technical Field
[0001] The utility model relates to the technical field of gravure printing machines, in particular to an embossing device of a gravure printing machine. Background Art
[0002] A gravure printing machine is a machine that uses gravure to print. The entire plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a doctor blade, leaving the ink on the image part, and then passing through the film. The impression roller is pressed on the back of the film, so that the ink in the concave part is directly transferred to the paper surface, and finally the printed matter is piled or rewound by winding, thus completing the printing of a printed matter. The impression roller is an important component in a printing device, usually made of metal or plastic, and the surface is specially treated to improve wear resistance and corrosion resistance. It is mainly used to apply pressure during the printing process so that the ink can better adhere to the printing material, while ensuring the clarity and consistency of the printed pattern.
[0003] At present, the embossing roller on the gravure printing machine will be contaminated with dirt such as ink, paper fibers and dust after being used for a period of time. These dirts will affect the printing quality and the life of the embossing roller, which will cause the staff to clean the embossing roller regularly. However, at present, when the staff cleans the embossing roller, the embossing roller cannot continue to emboss the printed product, and the gravure printing machine cannot continue to print, thereby reducing work efficiency.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 As shown, the embossing device of the gravure printing machine includes a mounting frame 1, and embossing roller bodies 2 are arranged on the upper and lower sides of the mounting frame 1. The printed product passes through the bottom of the embossing roller body 2 below, and the printed product is embossed by the embossing roller body 2 below. The left and right sides of the mounting frame 1 are provided with a shifting structure 3 for adjusting the embossing roller bodies 2 on the upper and lower sides. The left and right surfaces of the mounting frame 1 are provided with fixed grooves 4, and the left and right sides of the embossing roller body 2 are fixed with connecting shafts 5, and the other end of the connecting shaft 5 passes through the fixed groove 4. A waste box 6 is arranged between the embossing roller bodies 2, and the length of the waste box 6 is the same as the length of the embossing roller body 2. Fixed platforms 7 are fixed below the left and right sides of the mounting frame 1, and a driving structure 8 is arranged on the surface of the fixed platform 7, and a connecting rod 9 is fixed on the front side of the driving structure 8.
[0022] The transposition structure 3 includes a fixed frame 31, a first gear 32, a dual-axis motor 33 and a second gear 34. The fixed frame 31 is fixed above the left and right sides of the mounting frame 1. The first gear 32 is rotatably connected to the surface of one side of the fixed frame 31. One end of the connecting shaft 5 is rotatably connected to the surface of the first gear 32. The dual-axis motor 33 is fixed below the left and right sides of the mounting frame 1. The second gear 34 is fixed to one end of the output shaft of the dual-axis motor 33. The diameter of the first gear 32 is equal to twice the diameter of the second gear 34, and the first gear 32 and the second gear 34 are meshed. When the staff turns on the dual-axis motor 33, the second gear 34 drives the upper first gear 32 to rotate. The diameter of the first gear 32 is equal to twice the diameter of the second gear 34. When the lower second gear 34 rotates one circle, the upper first gear 32 rotates half a circle, so that the positions of the upper and lower embossing roller bodies 2 are swapped for subsequent embossing work.
[0023] The driving structure 8 includes a rotating disk 81, a fixed block 82, a movable frame 83 and a push rod 84. The rotating disk 81 is rotatably connected to the surface of one side of the fixed platform 7. The output shaft of one side of the dual-axis motor 33 penetrates the fixed platform 7 and is fixedly connected to the surface of the rotating disk 81. The fixed block 82 is fixed to one side of the surface of the rotating disk 81. The movable frame 83 is arranged on the surface of the rotating disk 81, and the fixed block 82 penetrates the movable frame 83 and is slidably connected to the inner wall of the movable frame 83. The push rod 84 is fixed to the front side of the movable frame 83. The front end of the push rod 84 is fixedly connected to one end of the connecting rod 9. A guide sleeve 11 is fixed in front of the surface of one side of the fixed platform 7. The push rod 84 passes through the guide sleeve 11 and is slidably connected to the inner wall of the guide sleeve 11. When the dual-axis motor 33 is turned on, the rotating disk 81 on one side also rotates. When the output shaft of the dual-axis motor 33 drives the second gear 34 on one side to rotate one circle, the rotating disk 81 on one side also rotates one circle. When the rotating disk 81 rotates, the fixed block 82 also moves, so that the movable frame 83 pushes the front push rod 84 to move. The guide sleeve 11 guides the push rod 84, so that the push rod 84 pushes the connecting rod 9 to move back and forth. After the rotating disk 81 rotates one circle, the waste box 6 moves forward and then moves back to its original position.
[0024] There are card slots 10 on the left and right sides of the front of the waste box 6. The end of the connecting rod 9 away from the push rod 84 extends to the inside of the card slot 10 and is engaged with the inner wall of the card slot 10. When a lot of dust or ink accumulates inside the waste box 6, the staff can pull the waste box 6 to separate the waste box 6 from the connecting rod 9 so that the staff can clean the inside of the waste box 6.
[0025] Working principle: when the staff needs to clean the surface of the embossing roller body 2 located at the bottom, the staff can directly turn on the dual-axis motor 33 on both sides and control the output shaft of the dual-axis motor 33, so that the output shaft of the dual-axis motor 33 drives the second gear 34 on one side to rotate one circle, thereby making the first gear 32 above rotate half a circle, and the positions of the embossing roller bodies 2 on the upper and lower sides are swapped. When the first gear 32 rotates, the push rods 84 on both sides also drive the waste box 6 to move forward to avoid the embossing roller body 2 from colliding with the waste box 6. When the position of the embossing roller body 2 is swapped, the waste box 6 is reinserted between the embossing roller bodies 2. The embossing roller body 2 switched to the bottom can continue to emboss the printed product. During the printing process, the staff can use a cleaning tool to clean the surface of the upper embossing roller body 2. The dirt that falls after cleaning will fall on the surface of the waste box 6. The waste box 6 collects the dirt so that subsequent staff can clean it uniformly.
[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
