[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: an automated flexographic printing and die-cutting integrated equipment, including a machine body 1. A material roller is provided on the left side of the machine body 1 so that the material roller can install the material to be printed, and the material is printed by three sets of printing mechanisms 2. After printing, the material is cut off by the die-cutting mechanism 3 on the right side. The surface of the machine body 1 is provided with three sets of printing mechanisms 2, and the right side of the machine body 1 is provided with a die-cutting mechanism 3.

[0035] Reference Figure 2 and Figure 3 and Figure 5 The printing mechanism 2 includes a fixed base 21. A motor 29 is fixedly connected to the outer sidewall of the fixed base 21. The output shaft of the motor 29 is fixedly connected to a limiting block 210. The limiting block 210 is rotatably connected to the inner sidewall of the fixed base 21. A limiting groove is formed at the end of the printing roller 24. The outer wall of the limiting block 210 contacts the inner wall of the limiting groove of the printing roller 24. The insertion between the two allows the motor 29 to drive the limiting block 210 to rotate, which in turn drives the printing roller 24, whose surface is limited and inserted, to rotate synchronously. An ink cartridge 23 is provided at the top of the inner sidewall of the fixed base 21. The bottom end of the ink cartridge 23 contacts an ink coating roller 22. The ink cartridge 23 is a prior art technology. The ink roller 22 can be electro-adsorbed by rotating to adsorb the paint inside the ink cartridge 23 onto the surface of the ink roller 22, and the ink roller 22 can also adsorb the pigment onto the surface of the printing roller 24, so that the printing roller 24 can perform printing operations on the material when rotating. The printing roller 24 is detachably installed on the outer surface of the fixed base 21 through the quick-release assembly 26. Two sets of driven rollers 25 are rotatably connected to the inner side wall of the machine body 1. By setting two sets of driven rollers 25, the printing position of the printing material can be lifted, so that the printing roller 24 can print evenly on the surface of the material. An adjustment assembly 28 is provided on the inner wall at the bottom of the fixed base 21.

[0036] Reference Figure 4The adjustment assembly 28 also includes a bidirectional threaded rod 281. Two sets of sliders 282 are threadedly connected to the surface of the bidirectional threaded rod 281. The bidirectional threaded rod 281 is existing technology, with two sets of threads in opposite directions on its surface. A servo motor is installed at the bottom of the fixed base 21, which drives the bidirectional threaded rod 281 to rotate. The inner sidewall of the sliders 282 has an internal thread groove, allowing the rotation of the bidirectional threaded rod 281 to bring the two sets of sliders 282 closer together or further apart on their surfaces. A hinge rod a283 is hinged to the surface of the sliders 282. A connecting plate 284 is hinged to the end of the hinge rod a283 away from the slider 282. When the slider 282 moves along the threaded surface of the bidirectional threaded rod 281, it pulls the hinge rod a283 to move synchronously, thereby pushing the connecting plate 284 to the side of the bottom of the body 1. The wall moves up and down. The bidirectional threaded rod 281 is rotatably connected to the inner wall of the bottom end of the fixed seat 21. The connecting plate 284 is slidably connected to the inner side wall of the fixed seat 21. Both sides of the connecting plate 284 are hinged with hinge rods b285. The end of the hinge rod b285 away from the connecting plate 284 is hinged with a connecting rod 286. When the connecting plate 284 moves up and down due to the pull of the hinge rod a283, the hinge rods b285 on both sides will push the corresponding connecting rods 286 to move closer or further apart on the inner wall of the slide groove of the fixed seat 21, thereby adjusting the tension according to the thickness of different materials to prevent the printing effect from deteriorating due to different materials. The surface of the fixed seat 21 is provided with two sets of slide grooves. The outer wall of the connecting rod 286 is slidably connected to the inner wall of the slide groove of the fixed seat 21. The surface of the connecting rod 286 is rotatably connected with a tension roller 27.

[0037] Reference Figure 4 and Figure 6The quick-release assembly 26 includes a quick-release seat 261. A mounting groove is provided on the side wall of the fixed seat 21. The outer wall of the quick-release seat 261 contacts the inner wall of the mounting groove. This contact allows for positioning and installation of the quick-release seat 261. The printing roller 24 is rotatably connected to the inner side wall of the quick-release seat 261. When the end of the printing roller 24 is inserted into the limiting block 210 and driven by the rotation of the limiting block 210, the quick-release seat 261 is not affected. A handle 263 is elastically connected to the inner side wall of the quick-release seat 261 via a return spring 262. One end of the return spring 262 is fixedly connected to the bottom end of the outer wall of the handle 263, and the other end is fixedly connected to the inner side wall of the quick-release seat 261. The function of the return spring 262 is to automatically return the handle 263 to its original position after it is pulled down. The guide rod 264 is fixedly connected to the inner side wall of the quick-release seat 261. The guide rod 264 is slidably connected through the inner wall of the handle 263. The end of the handle 263 is hinged to the connecting rod 265. The end of the connecting rod 265 away from the handle 263 is hinged to the insert block 266. When the handle 263 is pulled down, it will simultaneously pull the two sets of connecting rods 265 to move synchronously. At the same time, since the insert block 266 can only move laterally, the descent of the handle 263 will pull the corresponding insert block 266 to move closer to each other through the two sets of connecting rods 265. The insert block 266 is slidably connected through the inner wall of the quick-release seat 261. The side wall of the mounting groove of the fixed seat 21 has a slot. The insert block 266 is inserted into the inner wall of the slot. The insertion between the two can fix the position of the quick-release seat 261 after the printing roller 24 is inserted with the limiting block 210.

[0038] Working principle: When processing different fabrics and adjusting the tension of the fabric printing, the servo motor at the bottom of the fixed seat 21 is first started, driving the bidirectional threaded rod 281 to rotate. Since the two sets of threads on the surface of the bidirectional threaded rod 281 rotate in opposite directions, and the inner side wall of the slider 282 has an internal thread groove, the rotation of the bidirectional threaded rod 281 causes the two sets of sliders 282 to move closer or further apart on their surfaces. The movement of the sliders 282 pulls the hinge rod a283, which in turn pushes the connecting plate 284 to move up and down on the bottom side wall of the machine body 1. When the connecting plate 284 moves, the hinge rods b285 on both sides push the corresponding connecting rods 286 to move closer or further apart on the inner wall of the groove of the fixed seat 21, thereby driving the tension roller 27 to adjust its position. The material tension is adjusted according to the different material thicknesses to prevent the printing effect from deteriorating due to material differences.

[0039] When installing the printing roller 24, pull down the handle 263. The handle 263 moves under the guidance of the guide rod 264, simultaneously pulling the two sets of connecting rods 265. Since the insert block 266 can only move laterally, the handle 263 descends and drives the insert block 266 to move closer together through the connecting rod 265. At this time, the quick-release seat 261 is installed on the inner wall of the mounting groove on the left side of the fixed seat 21. At this time, the end of the printing roller 24 is inserted into the outer wall of the limiting block 210, and the insert block 266 is inserted into the slot on the side wall of the mounting groove of the fixed seat 21, fixing the quick-release seat 261 and the position of the printing roller 24 after being inserted into the limiting block 210. When it is necessary to remove the printing roller 24, pull the handle 263 again to disengage the insert block 266 from the slot. Under the action of the return spring 262, the handle 263 automatically returns to its original position, facilitating quick replacement of the printing roller 24.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
