Description

Technical Field

[0001] This utility model relates to the field of paperboard technology, and in particular to a flexible printing device. Background Technology

[0002] After cardboard is formed, its surface needs to be printed. Cardboard printing is generally done using flexographic printing equipment with flexographic printing plates. This means that ink is transferred to the printing plate roller through the inking roller, and then the cardboard is pressed tightly against the surface of the printing plate roller under the pressure of the extrusion roller, thus achieving printing on the cardboard. Currently, flexographic printing on the market has shortcomings, such as a fixed structure, which makes it impossible to adjust the distance between the extrusion roller and the printing plate roller, and it cannot be applied to cardboard of different thicknesses. Moreover, the fixed structure of the doctor blade and the inking roller makes it easy for the doctor blade to collide with the inking roller when they come into contact, which greatly reduces the effect of doctoring. Utility Model Content

[0003] The purpose of this invention is to design a flexible printing device to overcome the shortcomings of the above-mentioned technologies.

[0004] This utility model designs a flexible printing device, including a frame, on which a conveying component and a printing component are provided. The conveying component is used to convey paperboard to the printing component for printing. The printing component includes a squeeze roller and a printing plate roller rotatably connected to the frame. The squeeze roller is located to the side of the printing plate roller and is movably connected to the frame. The paperboard is located between the printing plate roller and the squeeze roller. An inking roller is provided to the side of the printing plate roller, and an ink supply box is provided below the inking roller. An ink feeding roller is provided between the inking roller and the printing plate roller, and an ink scraping mechanism is provided to the side of the ink feeding roller to scrape ink off the ink feeding roller.

[0005] Preferably, the conveying assembly includes an upper support frame and a lower support frame connected to the frame. The upper support frame and the lower support frame are respectively provided with an upper conveying roller and a lower conveying roller. The paperboard is located between the upper conveying roller and the lower conveying roller and is conveyed to the printing assembly through the upper conveying roller and the lower conveying roller. The upper support frame is rotatably connected to the frame, and the frame is provided with a driving component for driving the upper support frame to rotate.

[0006] In a further optimization, the conveying assembly also includes a dust removal roller, which is connected to the lower support frame and close to the lower conveying roller.

[0007] Preferably, the extrusion roller is provided with a mounting base, and a transmission structure is provided between the mounting base and the frame, so that the extrusion roller can reciprocate along the frame in the same axis as the printing plate roller, and can also move up and down relative to the frame.

[0008] Further optimization includes a transmission structure comprising a guide rail disposed on the frame and distributed along the axial direction of the extrusion roller, and a slider on the mounting base that slides with the guide rail; a fixing block is provided between the mounting base and the extrusion roller, and a second driving component is provided on the mounting base. The lifting end of the second driving component is connected to the fixing block, and the extrusion roller can move up and down relative to the frame through the second driving component to achieve the extrusion roller pressing down toward the printing plate roller.

[0009] Further optimization involves the following: the second driving component includes a cylinder and a pressure regulating valve. The output end of the cylinder is a lifting end to drive the extrusion roller to press down. The pressure regulating valve is located on the cylinder to adjust the degree of pressing down of the extrusion roller.

[0010] Preferably, the ink-scraping mechanism includes a doctor blade and a movable plate. The doctor blade is rotatably connected to the movable plate, and the movable plate is rotatably connected to the frame. A driving component is provided between the frame and the movable plate to drive the movable plate to rotate. The ink roller is mounted on the movable plate.

[0011] Further optimization includes a doctor blade comprising a roller rotatably connected to a movable plate, a doctor blade holder on the roller, a doctor blade on the doctor blade holder, a fixed beam extending in the same direction as the doctor blade holder on the movable plate, a floating pin slidably connected to the fixed beam, the sliding direction of the floating pin being perpendicular to the extension direction of the fixed beam, a first spring between the floating pin and the fixed beam, and a pressing member on the doctor blade holder extending above the floating pin and making point contact with the floating pin, so that the floating pin elastically floats relative to the fixed beam under the pressing force of the pressing member.

[0012] Further optimization involves providing a mounting hole on the cutter holder, installing a fastener within the mounting hole, connecting the cutter holder to the roller body via the fastener, and providing a second spring between the fastener and the cutter holder.

[0013] Further optimization involves providing an oblong hole on the movable plate, with the rotating end of the roller inserted into the oblong hole and able to reciprocate along the length of the oblong hole. An adjusting screw is provided on the movable plate, with the top end of the adjusting screw extending into the oblong hole and abutting against the peripheral wall of the rotating end of the roller.

An elastic floating pin is provided between the doctor blade and the blade holder, allowing the doctor blade to have elastic cushioning relative to the inking roller, further achieving a flexible setting for the doctor blade. The pressure roller is located above the printing plate roller and is connected to the frame through a transmission structure, allowing the pressure roller to slide axially and move up and down relative to the printing plate roller along the frame. This allows the pressure roller to adapt to paperboards of different thicknesses and provides good flexibility. The overall structure is compact and highly integrated, reducing the equipment's footprint and maintenance costs. Operation is simple, and printing efficiency is improved. The design of the doctor blade mechanism improves the efficiency and uniformity of the doctor blade, enhancing print quality. Attached Figure Description

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] This utility model includes a frame 1, on which a conveying assembly 3 and a printing assembly 2 are provided. The conveying assembly 3 is used to convey paperboard to the printing assembly 2 for printing. The printing assembly 2 includes a pressure roller 2-1 and a printing plate roller 2-2 rotatably connected to the frame 1. The pressure roller 2-1 is located to the side of the printing plate roller 2-2 and is movably connected to the frame 1. The paperboard is located between the printing plate roller 2-2 and the pressure roller 2-1. The paperboard is conveyed to the space between the printing plate roller 2-2 and the pressure roller 2-1 through the conveying assembly 3. The pressure roller 2-1 moves relative to the printing plate roller 2-2 to squeeze the paperboard, so that the paperboard is close to the surface of the printing plate roller 2-2. The printing plate roller 2-2 prints on the paperboard. In this embodiment, the pressure roller 2-1 is located directly above the printing plate roller 2-2. The pressure roller 2-1 presses down so that the lower surface of the paperboard is tightly attached to the printing plate roller 2-2, thereby achieving printing on the lower surface of the paperboard.

[0025] The printing plate roller 2-2 has an ink-dipping roller 2-3 on its side, and an ink supply box 2-4 is located below the ink-dipping roller 2-3. The bottom of the ink-dipping roller 2-3 is immersed in the ink supply box 2-4. An ink-applying roller 2-5 is located between the ink-dipping roller 2-3 and the printing plate roller 2-2. The ink-dipping roller 2-3 rotates to wrap the ink in the ink supply box 2-4, and then transfers it to the printing plate roller 2-2 through the ink-applying roller 2-5, so that the printing plate roller 2-2 can infuse ink and print on the paperboard.

[0026] A scraping mechanism for scraping ink from the ink roller 2-5 is provided on the side of the ink roller 2-5. The scraping mechanism includes a scraper blade 2-11 and a movable plate 2-12. The movable plate 2-12 is respectively set on the two rotating ends of the scraper blade 2-11 to form a rotatable connection. The two movable plates 2-12 are hinged to the frame 1. In this embodiment, a separate mounting plate 2-14 can be set on the frame 1. The scraping mechanism is mounted on the frame 1 through the mounting plate 2-14. The movable plate 2-12 is hinged to the mounting plate 2-14, so that the scraping mechanism can be installed and removed from the frame 1 as a whole through the mounting plate 2-14, which is very convenient. There are two mounting plates 2-14, located at both ends of the printing plate roller 2-2. The printing plate roller 2-2 is rotatably connected to the mounting plate 2-14 and its top. The bottom end of the movable plate 2-12 is hinged to the bottom of the mounting plate 2-14. The inking roller 2-5 is rotatably connected to the top of the movable plate 2-12. A driving component 2-13 is provided between the mounting plate 2-14 and the movable plate 2-12 to drive the movable plate 2-12 to rotate relative to the mounting plate 2-14 around the hinge point. This allows the movable plate 2-12 to be adjusted in position relative to the mounting plate 2-14, i.e., closer to or farther away from the mounting plate 2-14. Consequently, the doctor blade mechanism, along with the inking roller 2-5, can move closer to or farther away from the printing plate roller 2-2. Ultimately, the distance between the printing plate roller 2-2 and the inking roller 2-5 is adjustable to facilitate inking of the printing plate roller 2-2.

[0027] The doctor blade 2-11 includes a roller body 2-11-1 rotatably connected to a movable plate 2-12. The roller body 2-11-1, the inking roller 2-5, the printing plate roller 2-2, and the pressure roller 2-1 are all arranged coaxially. A blade holder 2-11-2 is provided on the roller body 2-11-1. The blade holder 2-11-2 is a long strip-shaped seat, arranged coaxially and parallel to the roller body 2-11-1. A doctor blade 2-11-3 is provided on the blade holder 2-11-2, and the doctor blade 2-11-3 is positioned along the blade holder 2-11-2, close to the inking roller 2-5. The -5 position is extended, and the doctor blade 2-11-3 scrapes ink from the surface of the inking roller 2-5, ensuring uniform ink distribution. The movable plate 2-12 also has a fixed beam 2-11-4 extending in the same direction as the blade holder 2-11-2. The fixed beam 2-11-4 has radial through holes along its length, and a floating pin 2-11-5 is slidably mounted within these holes. The sliding direction of the floating pin 2-11-5 is perpendicular to the extending direction of the fixed beam 2-11-4. A first spring 2-11-6 is provided between pin 2-11-5 and fixed beam 2-11-4, allowing floating pin 2-11-5 to elastically float up and down relative to fixed beam 2-11-4. A pressing member 2-11-7 is provided on the blade holder 2-11-2. One end of the pressing member 2-11-7 is connected to the blade holder 2-11-2, and the other end extends above floating pin 2-11-5 and makes point contact with floating pin 2-11-5. When the doctor blade 2-11-3 scrapes ink from the ink roller 2-5, it will... The doctor blade 2-11-3 and the blade holder 2-11-2 rotate, which causes the lower pressure component 2-11-7 to rotate under the influence of the blade holder 2-11-2. This causes the lower pressure component 2-11-7 to press down on the floating pin 2-11-5. Ultimately, the floating pin 2-11-5 floats elastically relative to the fixed beam 2-11-4 under the downward pressure of the lower pressure component 2-11-7, allowing the doctor blade 2-11 to form an elastic offset during ink scraping, thus preventing the doctor blade 2-11 from making a hard collision with the ink roller 2-5.

[0028] The conveying assembly 3 includes an upper support frame 3-1 and a lower support frame 3-2 connected to the frame 1. Both the upper support frame 3-1 and the lower support frame 3-2 are located in front of the printing plate roller 2-2 and are distributed vertically. The upper support frame 3-1 is hinged to the frame 1. The frame 1 is provided with a drive component 3-5 that drives the upper support frame 3-1 to rotate. The upper support frame 3-1 and the lower support frame 3-2 are respectively provided with an upper conveying roller 3-3 and a lower conveying roller 3-4. The upper conveying roller 3-3 and the lower conveying roller 3-4 are distributed vertically to form a set of conveying rollers. Multiple sets of conveying rollers can be set. The upper conveying roller 3-3 can be adjusted in pressure position through the support frame. The upper conveying roller 3-3 is connected to a drive component 4 and rotates autonomously under the drive of the drive component 4, so that the paperboard can be stably conveyed to the printing assembly 2.

[0029] Furthermore, the conveying assembly 3 also includes a dust removal roller 3-6. In this embodiment, there are two sets of conveying rollers arranged side by side along the conveying direction. The dust removal roller 3-6 is located between the two sets of conveying rollers and is installed on the lower support frame 3-2 and close to the lower conveying roller 3-4. The surface of the dust removal roller 3-6 has a brush. During the conveying process of the cardboard, the cardboard passes through the dust removal roller 3-6, which removes dust from the lower surface of the cardboard. It is rotatably connected to the frame 1 and located in front of the lower conveying roller 3-4. The dust removal roller 3-6 can be rotatably connected or fixedly connected.

[0030] Furthermore, a mounting base 2-6 is provided on the extrusion roller 2-1, and a transmission structure is provided between the mounting base 2-6 and the frame 1, so that the extrusion roller 2-1 can reciprocate along the frame 1 in the same axis as the printing plate roller 2-2, and can also move up and down relative to the frame 1.

[0031] In this embodiment, the transmission structure includes a guide rail 2-7 mounted on the frame 1 and distributed along the axial direction of the extrusion roller 2-1. The mounting base 2-6 is provided with a slider 2-8 that slides with the guide rail 2-7. The position of the mounting base 2-6 can be adjusted by manually pushing the mounting base 2-6. Of course, an automated transmission structure can also be set between the mounting base 2-6 and the frame 1, such as a gear and rack structure, in which the gear is mounted on the mounting base 2-6 and the rack extends and is fixed along the frame 1. The gear meshes with the rack and the gear rotates forward and backward under the drive of the drive component, so that the mounting base 2-6 can slide back and forth along the frame 1; or a lead screw pair structure, in which the lead screw extends and is fixed along the frame 1, and the nut slides with the lead screw. The mounting base 2-6 is connected to the nut, and the mounting base 2-6 slides back and forth under the drive of the nut. It can also be a conventional transmission structure on the market, such as a synchronous belt transmission or a chain and sprocket transmission.

[0032] In addition, a fixing block 2-9 is provided between the mounting base 2-6 and the extrusion roller 2-1. A driving component 2-10 is provided on the mounting base 2-6. The lifting end of the driving component 2-10 is connected to the fixing block 2-9, so that the extrusion roller 2-1 can move up and down relative to the frame 1. Ultimately, the extrusion roller 2-1 can slide horizontally along the frame 1 and move vertically, that is, the extrusion roller 2-1 presses down toward the printing plate roller 2-2, thereby pressing the paperboard toward the printing plate roller 2-2 to achieve normal printing of the paperboard.

[0033] Furthermore, the driving component 2-10 includes a cylinder and a pressure regulating valve. The cylinder is mounted on the mounting base 2-6, and the output end of the cylinder is connected to the fixing block 2-9 to drive the fixing block 2-9 to rise and fall. The fixing block 2-9 drives the pressing roller 2-1 to rise and fall, so that the pressing roller 2-1 presses down toward the printing plate roller 2-2. The pressure regulating valve is set on the cylinder, and the air pressure of the cylinder is changed by the pressure regulating valve, thereby adjusting the downward pressure of the pressing roller 2-1 so that the pressing roller 2-1 can adaptively adjust the downward pressure for different paperboards.

[0034] Furthermore, the cutter holder 2-11-2 is provided with mounting holes, and fasteners such as bolts or screws are installed in the mounting holes. The cutter holder 2-11-2 is connected to the roller body 2-11-1 through the fasteners. A second spring 2-11-8 is provided between the fasteners and the cutter holder 2-11-2, so that an elastic buffer is formed between the cutter holder 2-11-2 and the roller body 2-11-1.

[0035] Furthermore, the movable plate 2-12 has an oblong hole 2-12-1. The rotating end of the roller body 2-11-1 is inserted into the oblong hole 2-12-1 and can reciprocate along the length of the oblong hole 2-12-1. The movable plate 2-12 is provided with an adjusting screw 2-12-2. The top end of the adjusting screw 2-12-2 extends into the oblong hole 2-12-1 and abuts against the peripheral wall of the rotating end of the roller body 2-11-1. Rotating the adjusting screw 2-12-2 causes the end of the adjusting screw 2-12-2 to push the rotating end of the roller body 2-11-1. The adjusting screws 2-12-2 on both sides simultaneously push the roller body 2-11-1, thereby realizing the adjustable distance between the roller body 2-11-1, i.e., the doctor blade 2-11-3, and the inking roller 2-5.

[0036] Drive component 1 (3-5), drive component 2 (2-10), drive component 3 (2-13), and drive component 4 can be conventional drive devices such as electric telescopic components, hydraulic components, or cylinders.

[0037] Furthermore, the printing plate roller 2-2 is equipped with a soft backing pad, which is usually made of single-sided film-coated foam material. It covers the roller body of the printing plate roller 2-2, and the printing plate surface is covered on the backing pad. When the cardboard is pressed down onto the printing plate surface of the printing plate roller, the printing plate surface forms a certain downward pressure buffer to avoid the deformation of the font or graphic on the printing plate surface due to excessive downward pressure of the cardboard, thereby affecting the printing effect.

[0038] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
