Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and specifically relates to an environmentally friendly printing device that integrates offset printing and digital printing. Background Technology

[0002] Offset printing is a type of planographic printing. Simply put, offset printing is a printing method that uses rubber to transfer the image on a printing plate to the substrate. Digital printing is the digitization of printing technology. It generally refers to the partial or complete digitization of the entire process. Examples include laser typesetting, remote plate transfer, digital proofing, computer-to-plate (CTP), digital workflows, and printing plant ERP systems. Offset printing and digital printing are connected in series via belt conveyors or transmission systems to achieve continuous production. Offset printing is used for large-volume basic printing, while digital printing is responsible for adding personalized or variable content, such as serial numbers and labels.

[0003] Chinese patent CN213261618U discloses an environmentally friendly printing equipment that integrates offset printing and digital printing, relating to the field of printing technology. The equipment includes a printing device body, a vacuum pump, and a water pump. Two sets of filter plates are symmetrically fixedly installed on both sides of the bottom of the printing device body, with the side of the filter plates furthest from each other connected to the air inlet of the vacuum pump. The air outlet of the vacuum pump is fixedly connected to a first fixed frame via a pipe, and a guide plate is fixedly installed at the bottom inner part of the first fixed frame. A spray plate is horizontally fixedly installed inside the first fixed frame, and the spray plate is connected to the water pump, which is fixedly installed at the top inner part of a water tank. A fourth fixed frame is fixedly installed at the center of the top of the first fixed frame, and a movable frame is inserted inside the fourth fixed frame. The top of the first fixed frame is connected to a drying device via a connecting pipe.

[0004] During offset printing, a large amount of waste gas is generated, which pollutes the entire workshop, endangers the health of employees, and causes the workshop to fail to meet environmental protection standards. The aforementioned document describes a method to ensure the neutralizing liquid can fully contact the waste gas, achieving harmless treatment and emission. However, when disassembling the third fixing frame to replace the activated carbon particles inside, it is cumbersome to move the limiting blocks on both sides of the third fixing frame one by one to release the limiting fixation.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an environmentally friendly printing device that integrates offset printing and digital printing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an environmentally friendly printing device that integrates offset printing and digital printing. It includes a conveyor belt, with a digital printing machine and an offset printing machine respectively mounted on the top of the conveyor belt. Two sets of lifting rollers are mounted on the outer surface of the conveyor belt, located below the digital printing machine and the offset printing machine respectively. The offset printing machine contains a suction fan, a filter assembly, and a first limiting assembly. The filter assembly is fixed inside the offset printing machine by the first limiting assembly. A storage assembly is mounted on the outer surface of the offset printing machine, and a second limiting assembly is mounted inside the storage assembly to limit and fix the storage assembly.

[0009] Furthermore, the filter assembly includes a frame, a filter screen is fixedly connected to the outer surface of the frame, activated carbon is filled inside the frame, square grooves are formed on the outer surface of the frame, the frame is slidably connected to the offset printing machine, and there are two sets of square grooves.

[0010] Furthermore, the first limiting component includes a screw, which is rotatably connected inside the offset printing machine. A limiting plate is threadedly connected to the outer surface of the screw, and a sliding plate is fixedly connected to the outer surface of the limiting plate. The sliding plate is used to insert into a square slot. Both the limiting plate and the sliding plate are slidably connected inside the offset printing machine. A rotating column is rotatably connected to the end of the screw, and a hexagonal groove is formed on the outer surface of the rotating column. There are two sets of both the limiting plate and the sliding plate.

[0011] Furthermore, the storage assembly includes a rotating plate, with a pin fixedly connected inside the rotating plate. A storage groove is provided on the outer surface of the offset printing machine. The rotating plate is rotatably connected to the inside of the storage groove via the pin, and a clip is fixedly connected inside the storage groove.

[0012] Furthermore, the second limiting component includes a limiting slider, on the outer surface of which a push block and a spring are fixedly connected respectively. The outer surface of the rotating plate is provided with a sliding groove, and the limiting slider and the push block are slidably connected inside the sliding groove. One end of the spring is fixedly connected inside the sliding groove. The limiting slider is used to be inserted into the offset printing machine.

[0013] Furthermore, the outer surface of the pusher block is provided with several grooves.

[0014] Furthermore, a handle groove is provided on the outer surface of the frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model connects the screw and the limiting plate. Both sets of limiting plates are located on the outer surface of the screw. When the screw rotates, it can simultaneously drive the two sets of limiting plates to move the two sets of sliding plates. The two sets of sliding plates are inserted into the square grooves on both sides of the frame to limit and fix the frame. When the screw is reversed, the two sets of sliding plates can be separated from the frame at the same time to release the limiting and fixing of the frame. There is no need to move the sliding plates one by one, which is more convenient to use.

[0017] 2. This utility model connects the rotating plate and the clamp. After the hexagonal wrench that drives the screw to rotate is placed into the clamp, the clamp limits the hexagonal wrench. Then the rotating plate is closed to protect the clamp and the hexagonal wrench, which can prevent the wrench from being lost. When it is necessary to drive the screw to rotate, the tool can be directly taken out from the nearby clamp, which is quite convenient.

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is an environmentally friendly printing device that integrates offset printing and digital printing. It includes a conveyor belt 1, on the top of which a digital printing machine 2 and an offset printing machine 3 are respectively arranged. The outer surface of the conveyor belt 1 is provided with lifting rollers 4. There are two sets of lifting rollers 4, which are located below the digital printing machine 2 and the offset printing machine 3 respectively. The interior of the offset printing machine 3 is provided with a suction fan 5, a filter assembly 6, and a first limiting assembly 7. The filter assembly 6 is fixed inside the offset printing machine 3 by the first limiting assembly 7. The outer surface of the offset printing machine 3 is provided with a storage assembly 8. The interior of the storage assembly 8 is provided with a second limiting assembly 9, which is used to limit and fix the storage assembly 8.

[0031] After placing the substrate on top of conveyor belt 1, start conveyor belt 1 to move the substrate to below digital printing press 2. Start the lifting roller 4 below digital printing press 2, causing it to move the substrate upwards and into contact with digital printing press 2. Digital printing press 2 receives the electronic file, uses a raster image processor to parse the file into a high-precision dot matrix image, and controls the operation of the print head or imaging unit for printing. After printing, the substrate continues to move along conveyor belt 1 to below offset printing press 3. Start the lifting roller 4 below offset printing press 3 to lift the substrate and bring it into contact with the impression cylinder in offset printing press 3. The blanket roller in offset printing press 3... The printing cylinder transfers the image on the printing plate cylinder, and the impression cylinder presses the image on the blanket onto the substrate. Alternatively, a digital printing press 2 or an offset printing press 3 can be used separately as needed. The suction fan 5 inside the offset printing press 3 is started, and the suction fan 5 sucks away the exhaust gas generated during the operation of the offset printing press 3 and makes it pass through the filter assembly 6. After being filtered by the filter assembly 6, it is discharged, achieving the purpose of environmental protection. When the filter assembly 6 needs to be replaced, push the second limit assembly 9 to release the limitation fixation on the storage assembly 8, take out the tool from the storage assembly 8, and rotate the first limit assembly 7 to release the limitation fixation on the filter assembly 6, so that the filter assembly 6 can be removed for replacement.

[0032] This utility model connects the filter assembly 6 and the first limiting assembly 7. The two parts of the first limiting assembly 7 are located on both sides of the filter assembly 6. The limiting parts of the first limiting assembly 7 located on both sides of the filter assembly 6 can be driven at the same time. Thus, when the first limiting assembly 7 is driven to move on one side, the limiting fixation on both sides of the filter assembly 6 can be released at the same time, which is more convenient to use.

[0033] In one embodiment, the filter assembly 6 includes a frame 601, a filter screen 602 fixedly connected to the outer surface of the frame 601, activated carbon 603 filled inside the frame 601, a square groove 604 formed on the outer surface of the frame 601, and the frame 601 slidably connected to the offset printing machine 3. There are two sets of square grooves 604.

[0034] After the frame 601 is filled with activated carbon 603, the frame 601 is pushed into the offset printing machine 3. After the suction fan 5 in the offset printing machine 3 is started, the suction fan 5 draws in the exhaust gas and blows the exhaust gas through the activated carbon 603 in the frame 601. The pollutants in the exhaust gas are adsorbed by the activated carbon 603 and discharged from the filter screen 602.

[0035] In one embodiment, the first limiting component 7 includes a screw 701, which is rotatably connected to the inside of the offset printing machine 3. A limiting plate 702 is threadedly connected to the outer surface of the screw 701. A sliding plate 703 is fixedly connected to the outer surface of the limiting plate 702. The sliding plate 703 is used to insert into the square groove 604. Both the limiting plate 702 and the sliding plate 703 are slidably connected to the inside of the offset printing machine 3. A rotating column 704 is rotatably connected to the end of the screw 701. A hexagonal groove 705 is formed on the outer surface of the rotating column 704. There are two sets of both the limiting plate 702 and the sliding plate 703.

[0036] After the frame 601 is installed into the offset printing machine 3, the hex wrench is inserted into the hexagonal slot 705. Then, the rotating column 704 is rotated by the hex wrench. The rotating column 704 drives the screw 701 to rotate. The rotation trend of the upper limit plate 702 of the screw 701 is blocked by the offset printing machine 3. At this time, the two sets of limit plates 702 on the screw 701 can drive the two sets of sliding plates 703 to move in the offset printing machine 3, so that the sliding plates 703 are inserted into the square slot 604, thereby limiting and fixing the frame 601. When it is necessary to release the limiting and fixing of the frame 601, simply reverse the screw 701.

[0037] In one embodiment, the storage component 8 includes a rotating plate 801, a pin 802 is fixedly connected inside the rotating plate 801, a storage groove 803 is provided on the outer surface of the offset printing machine 3, the rotating plate 801 is rotatably connected to the inside of the storage groove 803 through the pin 802, and a clip 804 is fixedly connected inside the storage groove 803.

[0038] Push the rotating plate 801 to rotate it via the pin 802. The rotating plate 801 rotates out of the storage slot 803, exposing the clip 804 inside the storage slot 803 to the field of vision. At this time, the staff can put the hex wrench into the clip 804 or remove the hex wrench from the clip 804 to avoid losing the hex wrench.

[0039] In one embodiment, the second limiting component 9 includes a limiting slider 901. A push block 902 and a spring 903 are fixedly connected to the outer surface of the limiting slider 901. A groove 904 is provided on the outer surface of the rotating plate 801. The limiting slider 901 and the push block 902 are slidably connected inside the groove 904. One end of the spring 903 is fixedly connected inside the groove 904. The limiting slider 901 is used to insert into the offset printing machine 3.

[0040] Pushing the push block 902 drives the limiting slider 901, causing the limiting slider 901 to slide in the slide groove 904 and compress the spring 903. At this time, the limiting slider 901 separates from the offset printing machine 3 and returns to the rotating plate 801, which can release the limiting fixation of the rotating plate 801.

[0041] In one embodiment, the outer surface of the push block 902 is provided with a plurality of grooves 10.

[0042] The grooves 10 on the surface of the push block 902 make the surface of the push block 902 uneven, thereby increasing the friction between the operator's fingers and the push block 902 and preventing slippage when pushing the push block 902 to move.

[0043] In one embodiment, the outer surface of the frame 601 is provided with a handle groove 11.

[0044] By inserting your hand into the handle groove 11, you can pull the frame 601 to move it, making it easy to install and remove the frame 601.

[0045] Through the above technical solution, 1. By connecting the screw 701 and the limiting plate 702, both sets of limiting plates 702 are located on the outer surface of the screw 701. When the screw 701 rotates, it can simultaneously drive the two sets of limiting plates 702 to move the two sets of sliding plates 703. The two sets of sliding plates 703 are inserted into the square grooves 604 on both sides of the frame 601, which can limit and fix the frame 601. When the screw 701 is reversed, the two sets of sliding plates 703 can be separated from the frame 601 at the same time to release the limitation and fixation of the frame 601. There is no need to move the sliding plates 703 one by one, which is more convenient to use. 2. Through the connection between the rotating plate 801 and the clamp 804, after the hex wrench that drives the screw 701 to rotate is placed into the clamp 804, the clamp 804 limits the hex wrench. Then the rotating plate 801 is closed to protect the clamp 804 and the hex wrench, which can prevent the wrench from being lost. When it is necessary to drive the screw 701 to rotate, the tool can be directly taken out from the nearby clamp 804, which is quite convenient.
