Description

Printing device capable of indentation

Technical Field

The utility model relates to the technical field of printing devices, in particular to an indentation-capable printing device.

Background

A printing unit is a unit that transfers ink of a graphic on a printing plate to a sheet of paper. Modern printing devices are often provided with an indentation function. Whether offset, gravure or flexo presses, they generally contain devices or accessories that are dedicated to the indentation operation.

Indentations are depressions, marks or imprints formed on paper or other materials by the application of pressure to enhance the bendability, handleability and recognizability of the material. However, in current printing jobs, the hardness of paper may be different for different materials due to the different specifications of the paper. Thus, when the indentation mechanism in the same printing device can form indentations on the surface of the paper with lower hardness, it may be difficult to form indentations on the surface of the paper with higher hardness; in contrast, the creasing mechanism may form a crease on the surface of a sheet of higher hardness, and may cause excessive creasing or even breakage of the sheet when facing the sheet of lower hardness. Therefore, the same indentation mechanism is difficult to be suitable for indentation operation of paper with different hardness, and the application range is small. In view of this, we propose an impressionable printing unit.

Further, as shown in fig. 2, the printing apparatus includes an indentation mechanism 3 for forming an indentation on the paper sheet when the paper sheet moves, and the indentation mechanism 3 is disposed on a side surface of the printing module 2. The creasing mechanism 3 comprises a platen 31, an outer ring of the platen 31 is provided with creasing rings 32, and the creasing rings 32 are used for creasing the surface of paper when the creasing rings 32 are contacted with the paper. Positioning columns 33 are arranged on two sides of the pressure plate 31, and the positioning columns 33 and the pressure plate 31 rotate synchronously. The two sets of positioning columns 33 are connected with a mounting frame 34 in a co-rotating manner through bearings, the pressure plate 31 rotates in the mounting frame 34 by taking the positioning columns 33 as rotating shafts, and the in-situ rotation is kept in the mounting frame 34. The installation frame 34 is the setting of below open-ended "protruding" font, and four fixed cover 35 of fixedly connected with are fixed cover 34, and sliding connection has spacing dish 36 in the fixed cover 35, and the top fixedly connected with connecting rod 37 of spacing dish 36, connecting rod 37 sliding connection are in fixed cover 35 equally, and spacing dish 36 is used for preventing connecting rod 37 from breaking away from in fixed cover 35 when sliding, and then prevents that installation frame 34 from dropping. The top ends of the plurality of groups of connecting rods 37 are fixedly connected with a moving plate 38, and the moving plate 38 drives the connecting rods 37 to synchronously move during movement. Four groups of springs 39 are arranged between the moving plate 38 and the mounting frame 34, one ends of the springs 39 are fixedly connected with the moving plate 38, and the springs 39 are used for releasing elastic force to enable the indentation ring 32 to downwards press on the surface of paper, so that the paper can be indented when moving, and meanwhile damage of the paper caused by excessive mechanical force is prevented.

Still further, referring to fig. 3, the printing apparatus further includes an adjusting component 4 for adjusting the pressure of the indentation mechanism 3, so that the indentation mechanism 3 can form indentations on the surfaces of materials with different hardness. The adjusting assembly 4 comprises a top plate 41 arranged on the top of the printing module 2, wherein the top plate 41 is arranged in a Z shape, and the position of the top plate 41 is fixed. Two groups of fixing plates 42 are fixedly connected to the side face of the printing module 2, and the positions of the fixing plates 42 are fixed. A limiting rod 43 is fixedly connected between the top plate 41 and one group of fixed plates 42, a limiting sleeve 44 is sleeved on the outer ring of the limiting rod 43, the limiting sleeve 44 is slidably connected onto the limiting rod 43, one side of the limiting sleeve 44 is fixedly connected with the moving plate 38, and the limiting sleeve 44 and the moving plate 38 synchronously move to be used for moving the moving plate 38 under the limiting action of the limiting rod 43. The top of the top plate 41 is also provided with a servo motor 45, the output end of the servo motor 45 penetrates through the top plate 41 and is fixedly connected with a threaded rod 46, and the servo motor 45 is used for driving the threaded rod 46 to synchronously rotate after being started. The bottom end of the threaded rod 46 is rotatably connected to the other set of fixed plates 42, and the threaded rod 46 remains rotated in place as it rotates. The outer ring of the threaded rod 46 is sleeved with a thread sleeve 47, and the thread sleeve 47 is in threaded connection with the threaded rod 46 and is used for driving the thread sleeve 47 to move along the length direction of the threaded rod 46 when the threaded rod 46 rotates. The threaded sleeve 47 is likewise fixedly connected to the movable plate 38, for the purpose of the threaded sleeve 47, when moved, of driving the movable plate 38 to move synchronously. So that the moving plate 38 presses the spring 39 when moving downward, so that the elastic force released by the spring 39 increases, and thus the force of the creasing ring 32 pressing against the paper increases, and the crease can be formed on the surface of the paper having higher hardness.

Meanwhile, when the paper moves, the indentation ring 32 contacts with the surface of the paper when passing under the pressure plate 31, so that the pressure plate 31 is driven to rotate by taking the mounting frame 34 as a rotating shaft when the paper moves, and the indentation ring 32 forms an indentation on the surface of the paper. In the case of higher hardness paper, the current creasing ring 32 may leave a shallower crease in the surface of the paper, making it difficult to achieve the standard, and thus requiring adjustment.

The servo motor 45 is started, the threaded rod 46 fixedly connected with the output end of the servo motor 45 starts to rotate, and the threaded rod 46 is in threaded connection with the threaded sleeve 47, so that the threaded sleeve 47 is driven to move downwards along the length direction of the threaded rod 46 when the threaded rod 46 rotates, and the movable plate 38 is driven to move downwards stably under the limiting action of the limiting rod 43 and the limiting sleeve 44. At this time, the indentation ring 32 is in contact with the electric conveyer belt 1, meanwhile, the moving plate 38 drives the connecting rod 37 and the limiting disc 36 to move downwards, and the spring 39 is compressed while the moving plate 38 moves, so that the mounting frame 34 can be pressed downwards by the elasticity released by the spring 39, and the indentation ring 32 is driven to press the electric conveyer belt 1. So that when the sheet moves, the creasing ring 32 presses down on the sheet when in contact with the sheet, thereby leaving a crease in the sheet having a higher hardness. At the same time, due to the arrangement of the spring 39, a buffer function exists, so that the paper is prevented from being damaged due to excessive downward extrusion mechanical force.

The above-described embodiment is only one alternative embodiment of the present utility model, and many alternative modifications and combinations of the above-described embodiment may be made by those skilled in the art based on the technical solutions of the present utility model and the related teachings of the above-described embodiment.
