Description

Technical Field

[0001] This utility model relates to the technical field of anti-ink-spinning components, specifically to an easily adjustable anti-ink-spinning component. Background Technology

[0002] A gravure printing machine, also known as a gravure printing press, is an industrial device that uses gravure printing technology as its core. It transfers ink to the surface of a substrate by carving grooves into a metal plate, thus printing patterns and text. The printing unit of a gravure printing machine typically consists of a plate cylinder and an impression cylinder. The plate cylinder is directly immersed in the ink tank, allowing the high-speed rotating ink to quickly fill the cylinder. Then, a doctor blade scrapes away the ink from the blank areas of the plate, leaving the ink in the image grooves. The impression cylinder then transfers the ink to the paper by rolling. However, under the pressure of the ink rollers, excess ink can be squeezed to the edge of the plate cylinder. Due to the uneven chamfering at both ends of the plate cylinder, and under centrifugal force, this excess ink can be quickly thrown out, resulting in ink splatter. To prevent this, appropriate anti-splatter components are used.

[0003] Chinese utility model patent CN214294954U discloses an anti-ink-splatter device and a gravure printing machine, including "a first clamping plate, a partition plate, a second clamping plate, a connecting plate, and a mounting plate, wherein the partition plate is installed between the first clamping plate and the second clamping plate, one end of the connecting plate is connected to the first clamping plate, and the other end of the connecting plate is connected to the mounting plate, the width of the partition plate is greater than the width of the first clamping plate, and the width of the partition plate is greater than the width of the second clamping plate. This anti-ink-splatter device has a simple structure and low manufacturing cost, and the partition plate is close to the top of the printing plate cylinder, resulting in good anti-ink-splatter effect." However, when the width of the paper is smaller than that of the printing plate cylinder, the anti-ink-splatter component is not easy to adjust according to the width of the paper, resulting in ink splatter on the portion of the printing plate cylinder that is wider than the width of the paper. This makes it difficult to adjust the anti-ink-splatter component according to requirements, thus reducing its adaptability and failing to meet the needs of the gravure printing machine. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable anti-ink-splatter component to solve the problem mentioned in the background art that when the width of the paper is smaller than the printing plate cylinder, the excess part on the printing plate cylinder still splatters ink, making it inconvenient to adjust the anti-ink-splatter component according to the requirements, and thus failing to meet the needs of gravure printing machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable anti-ink-splatter component, including an ink tank, a printing plate cylinder installed inside the ink tank, an impression cylinder arranged above the printing plate cylinder, a paper body arranged between the printing plate cylinder and the impression cylinder, a fixing component installed at one top end of the ink tank, and an anti-ink component installed inside the fixing component.

[0006] The fixing assembly includes a fixing clamp plate, an adjustment groove extending through the top of the fixing clamp plate, an adjustment plate attached to the inner wall of the top of the fixing clamp plate, an adjustment screw fixedly connected to one end of the adjustment plate, an adjustment nut connected to the external thread of the adjustment screw, and a connecting screw extending through one side of the adjustment plate.

[0007] The ink-resistant assembly includes a mating plate with a nut groove embedded in its back side. A mating nut is embedded inside the nut groove. An ink-resistant baffle is fixedly connected to the bottom of the back side of the mating plate. A limiting groove is embedded in one side of the ink-resistant baffle. Limiting grooves are embedded in both sides of the limiting groove. A limiting baffle is slidably connected inside the limiting groove.

[0008] The beneficial effects of this utility model are as follows: by setting an arc-shaped ink-proof baffle between the printing plate cylinder and the impression cylinder, ink splatter generated during gravure printing is protected, thus preventing ink splatter from occurring during gravure printing. At the same time, a sliding limit baffle is set inside the ink-proof baffle. When the paper width is small, the limit baffle can be adjusted so that the limit groove in the ink-proof baffle is between the two cylinders, thereby protecting against ink splatter and improving the adaptability of the ink splatter prevention component, making it easier to meet the needs of gravure printing machines.

[0009] To enable adjustment of the position of the anti-ink-spinning component in the ink tank:

[0010] Further configuration: the fixing clamp is a strip structure with a C-shaped cross section, and there are two fixing clamps in total. The inner wall of the fixing clamp is respectively in contact with the top outer wall of the adjusting plate and the ink tank. The adjusting screw is slidably connected to the inside of the adjusting groove, and the adjusting nut is connected to the adjusting screw and the top outer wall of the fixing clamp through a threaded connection to form a close-fitting connection structure.

[0011] By adopting the above technical solution, the fixing plate and the adjusting plate are fixed to the ink tank by using the adjusting screw and adjusting nut. At the same time, the adjusting groove is set to facilitate the adjustment of the lateral position of the adjusting plate in the fixing plate. It also facilitates the quick assembly and disassembly of the anti-ink-spinning component, thereby improving the efficiency of the anti-ink-spinning component.

[0012] To enable the ink-blocking baffle to connect with the adjustment plate:

[0013] The adjustment plate is further configured such that its back side is in contact with the front side of the docking plate, and the docking screw is threaded to the docking nut by passing through the docking plate.

[0014] By adopting the above technical solution, multiple sets of docking screws and docking nuts are set to connect the adjusting plate with the docking plate, which facilitates the quick replacement of the anti-ink baffle on the docking plate when needed, avoiding the cumbersome disassembly and assembly of the entire component when replacement is required, and improving the adaptability of the anti-ink-spinning component.

[0015] To protect the printing plate cylinder from ink spillage:

[0016] The ink-proof baffle is further configured as follows: the ink-proof baffle is an arc-shaped plate structure with an opening facing downwards, and the curvature of the ink-proof baffle is greater than that of the printing plate cylinder, and the ink-proof baffle is located between the printing plate cylinder and the impression cylinder.

[0017] By adopting the above technical solution, an ink-proof baffle is set at one end of the docking plate to protect against ink splashing. At the same time, the downward opening design also facilitates the guidance of the splashed ink into the ink tank, enhancing the ink-proof effect on the printing plate cylinder.

[0018] To allow the ink-blocking baffle to be adjusted according to the width of the paper:

[0019] The setting is further configured such that the length of the limiting groove is the same as the length of the adjusting groove, and when one end of the limiting baffle slides to the other end of the limiting groove, the other end of the limiting baffle and the other end of the ink-proof baffle form a through connection structure, and the two sides of the limiting baffle and the limiting slide groove form a sliding connection structure.

[0020] By adopting the above technical solution, a sliding limiting baffle is set inside the ink-proof baffle. When the paper width is short, the limiting groove in the ink-proof baffle can be made to protrude by sliding the limiting baffle, so that the limiting groove is located between the printing plate cylinder and the impression cylinder. This facilitates the ink-proof baffle to protect against ink splashes formed on the printing plate cylinder, improves the adaptability of the ink splash prevention component, and makes it easy to adjust the ink-proof baffle according to the width of the paper.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 5 The easily adjustable anti-ink-spinning component includes an ink tank 1, an ink cylinder 2 installed inside the ink tank 1, an impression cylinder 3 positioned above the ink cylinder 2, a paper body 4 positioned between the ink cylinder 2 and the impression cylinder 3, a fixing component 5 installed at one end of the top of the ink tank 1, and an anti-ink component 6 installed inside the fixing component 5.

[0030] The fixing component 5 includes a fixing clamp 501, an adjustment groove 502 passing through the top of the fixing clamp 501, an adjustment plate 503 attached to the inner wall of the top of the fixing clamp 501, an adjustment screw 504 fixedly connected to one end of the adjustment plate 503, an adjustment nut 505 connected to the external thread of the adjustment screw 504, and a mating screw 506 passing through one side of the adjustment plate 503.

[0031] The ink-blocking component 6 includes a mating plate 601, a nut groove 602 embedded in the back of the mating plate 601, a mating nut 603 embedded inside the nut groove 602, an ink-blocking baffle 604 fixedly connected to the bottom of the back of the mating plate 601, a limiting groove 605 embedded in one side of the ink-blocking baffle 604, limiting grooves 606 embedded in both sides of the limiting groove 605, and a limiting baffle 607 slidably connected inside the limiting groove 605.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the fixing clamp 501 is a strip structure with a C-shaped cross section, and there are two fixing clamps 501. The inner wall of the fixing clamp 501 is in contact with the top outer wall of the adjusting plate 503 and the ink tank 1, respectively. The adjusting screw 504 is slidably connected to the inside of the adjusting groove 502, and the adjusting nut 505 is threadedly connected to the adjusting screw 504 and the top outer wall of the fixing clamp 501 to form a close connection structure.

[0033] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the adjusting plate 503 has an L-shaped cross-section structure, and the back of the adjusting plate 503 is in contact with the front of the docking plate 601. The docking screw 506 forms a threaded connection structure with the docking nut 603 by passing through the docking plate 601.

[0034] In this embodiment, as Figure 1 and Figure 4 As shown, the ink shield 604 is an arc-shaped plate structure with an opening facing downwards, and the curvature of the ink shield 604 is greater than that of the printing plate cylinder 2, and the ink shield 604 is located between the printing plate cylinder 2 and the impression cylinder 3.

[0035] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the length of the limiting groove 605 is the same as the length of the adjusting groove 502, and when one end of the limiting baffle 607 slides to the other end of the limiting groove 605, the other end of the limiting baffle 607 and the other end of the ink-proof baffle 604 form a through connection structure, and the two sides of the limiting baffle 607 and the limiting slide groove 606 form a sliding connection structure.

[0036] The easily adjustable anti-ink-spinning component works as follows:

[0037] First, slide the limiting baffle 607, which slides in the limiting groove 605 inside the ink-proof baffle 604, along the limiting slide groove 606 to one end of the ink-proof baffle 604, so that the ink-proof baffle 604 and the limiting baffle 607 together form an arc-shaped whole.

[0038] Then, the ink-proof baffle 604 is attached to one side of the L-shaped adjusting plate 503 via the mating plate 601 on one side, and the mating screw 506 passes through the mating plate 601 and the adjusting plate 503, and is threadedly connected to the mating nut 603 embedded in the nut groove 602 on one side of the adjusting plate 503, thereby locking the mating of the mating plate 601 and the adjusting plate 503.

[0039] Next, the adjusting screw 504 at the top end of the horizontal plate inside the L-shaped adjusting plate 503 is passed through the adjusting groove 502, so that the top of the horizontal plate of the L-shaped adjusting plate 503 is in contact with the top inner wall of the fixed clamp 501. The groove of the fixed clamp 501 is engaged with the outer edge of the ink tank 1. By sliding the adjusting plate 503, one end of the ink-proof baffle 604 is positioned between the printing plate cylinder 2 and the impression cylinder 3. The adjusting nut 505 is rotated to lock the adjusting plate 503 inside the fixed clamp 501. The same operation is performed on the ink-proof baffle 604 at the other end of the printing plate cylinder 2 to complete the installation of the ink-proof assembly.

[0040] Finally, when the width of the paper used for gravure printing is short, slide the limiting baffle 607 inside the sliding ink-blocking baffle 604 so that the distance from one end of the limiting baffle 607 to one end of the limiting groove 605 is the same as the distance from one end of the paper body 4 to one end of the printing plate cylinder 2. Loosen the adjusting nut 505 and slide the adjusting screw 504 inside the adjusting plate 503 laterally along the adjusting groove 502 so that the gap between the printing plate cylinder 2 and the impression cylinder 3 is inside the limiting groove 605. Slide it until one end of the ink-blocking baffle 604 is on the same horizontal line as one end of the paper body 4. At this time, one end of the limiting baffle 607 inside the limiting groove 605 is located at one end of the printing plate cylinder 2. Lock the adjusting plate 503 with the adjusting nut 505 so that the ink-blocking baffle 604 can protect the end of the paper body 4 from ink splashing and avoid affecting the use of the printing plate cylinder 2 through the internal limiting groove 605. After the gravure printing is completed, the ink splashing prevention assembly can be disassembled and cleaned.
