Description

Technical Field

[0001] This utility model relates to the technical field of gravure printing, specifically a gravure printing machine blade holder mechanism. Background Technology

[0002] During printing, the entire printing plate is inked using the printing roller. The doctor blade scrapes away the ink from the blank areas, leaving only the ink for the image areas, which are then printed. Because the printing roller and doctor blade work closely together, the doctor blade needs to be adjustable in height and angle, and also needs to be able to wiggle left and right to prevent the blade from scraping ink from the same spot, thus reducing blade wear. Therefore, the doctor blade positioning device has adjustment mechanisms for height and angle to meet these adjustment requirements.

[0003] However, existing knife holders are all set up in fixed positions, which increases the difficulty of operation and the risk of accidental injury to operators when inserting printing film, placing ink trays or installing printing rollers in limited space. Utility Model Content

[0040] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0041] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0042] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0043] Please see Figures 1-6 In this embodiment of the present invention, a gravure printing machine blade holder mechanism includes two blade holder fixing seats 30 and a lifting mechanism 3 movably disposed between the two blade holder fixing seats 30 and capable of reciprocating movement. A blade table mechanism 2 is installed on the movable end of the lifting mechanism 3. The mechanism also includes a blade holder support fixing plate 35, on which the blade holder fixing seats 30 are slidably mounted to allow the blade holder fixing seats 30 to move laterally to a working position. A locking unit is installed on the blade holder fixing seats 30 or on a blade holder positioning plate 31 connecting the two blade holder fixing seats 30, for locking the relative position of the blade holder fixing seats 30 and the blade holder support fixing plate 35.

[0044] In this embodiment, the height of the blade holder mechanism 2 can be adjusted by the lifting mechanism 3 to adapt to different ink scraping requirements. At the same time, the blade holder support fixing plate 35 effectively supports the blade holder mechanism 2 and the lifting mechanism 3, and can move the blade holder mechanism 2 and the lifting mechanism 3 as a whole laterally when inserting the printing film, placing the ink tray or installing the printing roller. This effectively avoids the increased difficulty of operation and the risk of accidental injury to the operator due to operation errors caused by the use of the existing blade holder fixing method in the case of limited space. In addition, the locking unit can realize the flexibility and controllability of the blade holder mechanism 2 and the lifting mechanism 3, and ensure the stability during ink scraping.

[0045] It should be noted that the blade holder support fixing plate 35 is fixed on the wall plate 1, and there are two wall plates 1. The length of the blade holder support fixing plate 35 is greater than the distance between the two wall plates 1. The wall plate 1 is used to support the printing plate roller and is a support component in the printing machine. Therefore, this embodiment does not make specific limitations on it.

[0046] For details, please refer to Figure 1 and Figure 2At least one guide rail 4 is formed on the tool holder support fixing plate 35. Preferably, two guide rails 4 are provided. The tool holder fixing seat 30 is fixed with a slider 32 that is slidably connected to the guide rail 4 on the side facing the tool holder support fixing plate 35, thereby realizing the connection between the tool holder fixing seat 30 and the tool holder support fixing plate 35, which can ensure the effective support of the tool holder fixing seat 30, and at the same time facilitate the sliding of the tool holder fixing seat 30 relative to the tool holder support fixing plate 35.

[0047] The locking unit described above includes a tool holder positioning member 33 that is threadedly connected to the tool holder fixing seat 30 or the tool holder positioning plate 31. One end of the tool holder positioning member 33 is fixed with a tool holder positioning handwheel 34, and the other end can press against or disengage from the tool holder support fixing plate 35. By rotating the tool holder positioning handwheel 34, the tool holder positioning member 33 is driven to rotate, so as to move or move away from the tool holder support fixing plate 35. It cooperates with the positioning hole formed on the tool holder support fixing plate 35 to lock or unlock the tool holder fixing seat 30.

[0048] Further, please refer to Figure 2 and Figure 3 The tool holder mechanism 2 includes:

[0049] A first tool holder fixing seat 14 and a second tool holder fixing seat 221 are provided. A tool holder fixing adjustment shaft 13 is rotatably installed between the first tool holder fixing seat 14 and the second tool holder fixing seat 221. Specifically, both ends of the tool holder fixing adjustment shaft 13 pass through the first tool holder fixing seat 14 and the second tool holder fixing seat 221.

[0050] A first adjustment unit is installed on the blade holder fixing adjustment shaft 13. The movable end of the first adjustment unit is equipped with a blade holder 9. The blade holder 9 is detachably equipped with a doctor blade 5. Specifically, a second blade mounting plate 7 is fixed to the blade holder 9 by multiple blade mounting plate pressure plates 8. A first blade mounting plate 6 is fixed to the second blade mounting plate 7 by bolts. The doctor blade 5 is fixed between the first blade mounting plate 6 and the second blade mounting plate 7, thereby fixing the doctor blade 5. At the same time, when replacing the doctor blade 5, only the first blade mounting plate 6 needs to be removed, which is convenient for disassembly and assembly.

[0051] A tool holder rotation mechanism 22 is installed on the second tool holder fixing base 221 and connected to the tool holder fixing adjustment shaft 13. The tool holder rotation mechanism 22 is used to adjust the placement angle of the tool holder fixing adjustment shaft 13 relative to the first tool holder fixing base 14 and the second tool holder fixing base 221.

[0052] Further, please refer to Figure 2The first adjustment unit includes a tool holder sliding seat 12 and a lead screw fixing seat 15 fixed to each other. The tool holder sliding seat 12 is rotatably connected to the tool holder fixing adjustment shaft 13, and the lead screw fixing seat 15 is connected to the tool holder fixing adjustment shaft 13 through a telescopic adjustment component. A tool holder adjusting lead screw 17 is rotatably mounted on the lead screw fixing seat 15. The tool holder adjusting lead screw 17 is threadedly connected to a tool holder slider 11 slidably mounted on the tool holder sliding seat 12, and the tool holder slider 11 is detachably connected to the tool holder 9. A tool holder adjusting handwheel 19 is fixed at the end of the tool holder adjusting lead screw 17 away from the tool holder slider 11.

[0053] Rotating the knife-table adjustment handwheel 19 can drive the knife-table adjustment screw 17 to rotate. When the knife-table adjustment screw 17 rotates, it drives the knife-table slider 11 to move, thereby driving the knife-table 9 to move. This allows for adaptive adjustment of the position of the doctor blade 5 when it wears out, ensuring the fit between the doctor blade 5 and the printing roller and ensuring the doctoring effect.

[0054] It should be noted that the tool holder 9 is threadedly connected to a set handle screw 10. The set handle screw 10 passes through the tool holder 9 and abuts against the tool holder sliding seat 12. The set handle screw 10 is in the shape of a regular screw, with an additional handle added to the screw head to form a single unit. It is used to lock or loosen the tool holder 9 so that it can reach an adjustable or fixed state, thereby ensuring the stability of the tool holder 9 after adjustment.

[0055] Preferably, a position counter 20 is installed on the tool holder adjusting screw 17. Twisting the tool holder adjusting handwheel 19 will cause the tool holder adjusting handwheel 19 to rotate in the inner circle of the position counter 20 to achieve a counting effect, thereby improving the adjustment accuracy.

[0056] The aforementioned telescopic adjustment component includes a cylinder 18. One end of the cylinder 18 is hinged to a cylinder mounting base 21 fixed on the knife holder fixing adjustment shaft 13, and the other end is rotatably connected to a cylinder connecting shaft 16 fixed on the lead screw fixing base 15. When the cylinder 18 telescopically moves, it can drive the lead screw fixing base 15 and the entire assembly connected to the lead screw fixing base 15 to rotate relative to the knife holder fixing adjustment shaft 13, thereby controlling the rapid arrival or departure of the knife holder 9 and the doctor blade 5 from the printing roller.

[0057] Please see Figure 2 and Figure 3The tool holder rotation mechanism 22 includes a first worm gear 222 embedded in the second tool holder fixing seat 221 and fixedly connected to the tool holder fixing adjustment shaft 13, and a first worm 223 inserted into the second tool holder fixing seat 221 and rotatably connected to the second tool holder fixing seat 221 through a first thrust bearing 224. The first worm 223 meshes with the first worm gear 222. A handwheel 226 is fixed on the first worm 223 located outside the second tool holder fixing seat 221, and a tool holder fixing seat cover 225 is also installed on the second tool holder fixing seat 221 at a position where the first worm 223 protrudes.

[0058] By rotating the handwheel 226, the first worm gear 223 is driven to rotate. When the first worm gear 223 rotates, it drives the knife holder fixing adjustment shaft 13 to rotate through the action of the first worm wheel 222. This enables the entire assembly mounted on the knife holder fixing adjustment shaft 13 to follow the rotation, thereby adjusting the angle of the doctor blade 5 and ensuring a good doctoring effect during the printing process.

[0059] Please see Figures 2-5 A tool post lifting shaft 29 is rotatably mounted between the two tool post fixing seats 30, and a tool post positioning shaft 28 is slidably mounted between them. The lifting mechanism 3 is mounted on the tool post positioning shaft 28 and can slide along the axial direction of the tool post lifting shaft 29.

[0060] One of the tool holder fixing seats 30 is also equipped with a swing mechanism 24, which is connected to the tool holder positioning shaft 28 and is used to drive the tool holder positioning shaft 28 and the lifting mechanism 3 to reciprocate along the axial direction of the tool holder positioning shaft 28.

[0061] In this embodiment, the two ends of the blade holder positioning shaft 28 are connected to linear bearing seats 27 mounted on the blade holder fixing seats 30, thereby enabling the blade holder positioning shaft 28 to slide relative to the two blade holder fixing seats 30 along the axial direction of the blade holder positioning shaft 28. In conjunction with the swing mechanism 24, the lifting mechanism 3 is driven to move reciprocally in the horizontal direction, which is used to control the reciprocating movement of the blade holder relative to the printing plate roller. This can effectively prevent the problem of the doctor blade 5 being constantly in the same position and rubbing, which leads to excessive wear.

[0062] Please see Figure 2 , Figure 4 and Figure 5 The lifting mechanism 3 described above includes:

[0063] Two tool post lifting racks 237 are respectively fixed to the first tool post fixing seat 14 and the second tool post fixing seat 221. The two tool post lifting racks 237 pass through the tool post positioning shaft 28 and the first tool post lifting seat 231 and the second tool post lifting seat 25 slidably installed on the tool post lifting shaft 29.

[0064] Both the first tool holder lifting seat 231 and the second tool holder lifting seat 25 are rotatably installed with gears 239 that are slidably connected to the tool holder lifting shaft 29. The gears 239 mesh with the tool holder lifting rack 237. Tool holder lifting fixing seat cover 26 is fixed on the outer side of the first tool holder lifting seat 231 and the second tool holder lifting seat 25 through which the tool holder lifting shaft 29 passes.

[0065] It also includes a second adjustment unit disposed within the first tool holder lifting seat 231 and fixed to the gear 239.

[0066] In one exemplary embodiment, the second adjustment unit includes a tool holder lifting mechanism 23. The tool holder lifting mechanism 23 includes a second worm gear 236 fixedly connected to the gear 239. The second worm gear 236 has a through hole through which the tool holder lifting shaft 29 passes. The tool holder lifting shaft 29 and the second worm gear 236 are clearance-fitted. A second worm 232 is rotatably mounted on the inner side of the first tool holder lifting seat 231 via a second thrust bearing 238. The second worm 232 meshes with the second worm gear 236. One end of the second worm 232 protrudes from the first tool holder lifting seat 231 and is fixed with a tool holder lifting handwheel 233. A tool holder lifting handwheel adjustment cover 234 is installed on the first tool holder lifting seat 231 at the position where the second worm 232 protrudes.

[0067] It should also be noted that a flat key 235 is fixed on the tool holder lifting shaft 29. The flat key 235 slides in conjunction with the keyway formed on the gear 239, thereby enabling the tool holder lifting shaft 29 to rotate when the gear 239 rotates, without affecting the axial movement of the gear 239 relative to the tool holder lifting shaft 29.

[0068] Of course, the connection between the second worm gear 236 and the tool post lifting shaft 29 can also be achieved by using a keyway and a flat key 235. The specific choice can be made according to actual needs, and this embodiment does not impose any specific limitations on this.

[0069] The second worm gear 232 can be rotated by manually turning the tool holder lifting handwheel 233. When the second worm gear 232 rotates, it drives the second worm wheel 236 to rotate, thereby realizing the rotation of the tool holder lifting shaft 29. When the tool holder lifting shaft 29 rotates, it drives the tool holder lifting rack 237 to perform lifting and lowering movements through the action of the gear 239, thereby realizing the lifting and lowering adjustment requirements.

[0070] Please see Figure 6The swing mechanism 24 includes a reduction motor 241 fixed on the tool holder fixing seat 30. The output shaft of the reduction motor 241 is equipped with a tool holder eccentric wheel 242. A tool holder swing fixing member 244 is installed on the tool holder positioning shaft 28. The tool holder eccentric wheel 242 is connected to a bearing 243 set on the tool holder swing fixing member 244. When the reduction motor 241 works, it drives the tool holder eccentric wheel 242 to rotate. When the tool holder eccentric wheel 242 rotates, it drives the tool holder positioning shaft 28 to reciprocate through the action of the bearing 243 and the tool holder swing fixing member 244, thereby realizing the overall reciprocating movement of the lifting mechanism 3 and the tool holder mechanism 2. This can effectively prevent the problem of the doctor blade 5 being constantly in the same position and rubbing, which leads to excessive wear.

[0071] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0072] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
