Description

Technical Field

[0001] This utility model relates to the field of floor film printing technology, and in particular to an adjustable anilox roller scraping device for floor film printing machines. Background Technology

[0002] Floor film printing machines are mainly used to achieve multi-color printing on flat materials such as floor film, supporting the output of transitional colors and complex patterns, and are suitable for personalized and small-batch production needs.

[0003] Anilox roller is the core component of flexographic printing press. It is responsible for uniformly transferring a certain amount of ink onto the printing plate. The surface of the anilox roller is evenly distributed with many tiny concave holes of the same shape. These concave holes are usually called "inking holes". It is these inking holes that play the role of storing ink, evenly distributing ink and quantitatively transferring ink in printing.

[0004] A flexible printing anilox roller assembly with patent number CN202420743356.3 includes an installation mechanism, wherein a scraper mechanism is fixedly inserted into the inner wall of the installation mechanism; this solves the problem that in the current equipment, the anilox roller assemblies are mostly fixed and difficult to replace, resulting in inconvenience in installation and disassembly, which affects the use of the equipment.

[0005] However, the above patent has the following defects in actual use: Although the above patent can use a motor to drive the ink knife to adjust the angle, the ink knife has a fixed volume. This means that when the ink knife is driven by the motor to make an arc movement, only one or two points can contact the anilox roller. When it moves to other positions, there is a gap between the ink knife and the anilox roller, and it cannot perform effective ink scraping operation. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose an adjustable anilox roller ink scraping device for floor film printing machines.

[0007] The technical problem to be solved by this utility model is to provide an adjustable anilox roller doctoring device for floor film printing machines to solve the problem that the contact position between the ink knife and the anilox roller cannot be adjusted in existing models.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] An adjustable anilox roller ink scraping device for a floor film printing machine includes: a fixed frame, a fixed plate fixedly mounted on the fixed frame, a plurality of fixed holes formed on the fixed plate, an mounting frame fixedly mounted at the bottom of the fixed frame, a movable plate movably mounted inside the mounting frame, an ink knife fixedly mounted at the bottom of the movable plate, and two round shafts fixedly mounted on the left and right sides of the outer wall of the movable plate, the two round shafts respectively passing through the two sides of the outer wall of the mounting frame and movably connected to the outer wall of the mounting frame, a motor provided on the left side of the mounting frame, the power output end of the motor being fixedly connected to one end of the corresponding round shaft, and a lifting assembly provided on the right side of the mounting frame.

[0010] Preferably, a slider is rotatably connected through both of the two circular shafts, and a sliding groove is provided on both sides of the outer wall of the mounting bracket, with the slider slidably connected to the inner cavity of the corresponding sliding groove.

[0011] Preferably, a bracket is fixedly mounted on the outer wall of the motor, and the bracket is movably connected to the outer wall of the mounting frame.

[0012] Preferably, two limiting blocks are fixedly installed on the inner wall of the bracket, and two limiting grooves are opened on the outer wall of the mounting bracket, with the limiting blocks slidably connected to the inner cavity of the corresponding limiting grooves.

[0013] Preferably, the lifting assembly includes an electric push rod, a fixed block is fixedly installed on the top of the electric push rod and the fixed block is fixedly connected to the outer wall of the fixed frame, and a movable block is fixedly installed on the bottom of the electric push rod and the movable block is fixedly installed on the outer wall of the corresponding slider.

[0014] Preferably, the top and bottom of the electric actuator are respectively fitted and fixedly mounted on an upper metal washer and a lower metal washer, and the upper metal washer and the lower metal washer are respectively fixedly mounted on a fixed block and a movable block.

[0015] Preferably, the bottom of the movable plate is provided with a mounting groove, and the top of the ink knife is fixedly mounted with a mounting base, which is inserted into the inner cavity of the mounting groove.

[0016] Preferably, the mounting base has multiple threaded holes, the inner wall of the mounting groove has multiple round holes on both the front and rear sides, the front side of the movable plate has multiple bolts, the rear end of the bolt passes through two corresponding round holes and threaded holes and is threadedly connected to the threaded holes, and the rear end of the bolt is threadedly connected to a nut, the nut being located on the rear side of the movable plate.

[0017] In the above scheme, the motor drives the movable plate to deflect the ink knife at an angle, and then the electric actuator drives the ink knife to change its height. This allows the ink knife to adhere to various parts of the outer wall of the anilox roller to perform ink scraping operations. As a result, the overall device can adjust the position of the ink knife according to the actual situation and improve the ink scraping effect.

[0018] In the above solution, the fixed installation between the ink knife and the movable plate is achieved by setting bolts, and the ink knife can be easily disassembled and replaced after it wears out. Attached Figure Description

[0036] In this embodiment, as Figures 1-2 As shown, two limiting blocks 18 are fixedly installed on the inner wall of the bracket 17, and two limiting grooves 19 are opened on the outer wall of the mounting bracket 4. The limiting blocks 18 are slidably connected to the inner cavity of the corresponding limiting grooves 19.

[0037] Specifically, by setting the limiting block 18 and the limiting groove 19, the vertical movement trajectory of the bracket 17 can be limited, thereby improving stability.

[0038] In this embodiment, as Figures 1-3 As shown; the lifting assembly includes an electric push rod 21, a fixed block 20 is fixedly installed on the top of the electric push rod 21, the fixed block 20 is fixedly connected to the outer wall of the fixed frame 1, and a movable block 22 is fixedly installed on the bottom of the electric push rod 21, the movable block 22 is fixedly installed on the outer wall of the corresponding slider 14.

[0039] Specifically, the electric actuator 21 drives the movable block 22 to move, the movable block 22 drives the corresponding slider 14 to move, the slider 14 drives the circular shaft 13 to move, the circular shaft 13 drives the movable plate 5 to move, and the movable plate 5 drives the ink knife 7 to move, thereby achieving the purpose of adjusting the position of the ink knife 7.

[0040] In this embodiment, as Figures 1-3 As shown; the top and bottom of the electric actuator 21 are respectively fitted and fixedly installed on the upper metal washer 24 and the lower metal washer 23, and the upper metal washer 24 and the lower metal washer 23 are respectively fixedly installed on the fixed block 20 and the movable block 22.

[0041] Specifically, by using the cooperation of the upper metal washer 24 and the lower metal washer 23, the stability of the electric actuator 21 during operation can be improved.

[0042] In this embodiment, as Figure 5 As shown; the bottom of the movable plate 5 has an installation groove 6, and the top of the ink knife 7 is fixedly installed with an installation seat 8, which is inserted into the inner cavity of the installation groove 6.

[0043] Specifically, the above-mentioned settings make the installation between the ink knife 7 and the movable plate 5 convenient and easy to disassemble later.

[0044] In this embodiment, as Figure 5As shown; the mounting base 8 has multiple threaded holes 9, and the inner wall of the mounting groove 6 has multiple round holes 10 on both the front and rear sides. The front side of the movable plate 5 has multiple bolts 11.
