Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper flattening mechanism technology, specifically a paper flattening mechanism for paper printing. Background Technology
[0002] Before printing, the air environment and humidity can easily cause wrinkles on the paper surface, resulting in the pattern being printed on the wrinkles, which is not very attractive. Therefore, a flattening mechanism is usually used to flatten the paper before printing.
[0003] In the paper printing process, the flatness and cleanliness of the paper have a crucial impact on print quality. Traditional paper flattening mechanisms often suffer from uneven pressure distribution and poor flattening effect, leading to localized indentations or unevenness on the paper during printing, severely affecting the appearance quality of the printed product. Furthermore, paper easily accumulates dust, paper scraps, oil stains, and other contaminants during transport. If these contaminants are not removed promptly, they will transfer to the printing plate or ink during printing, further affecting print quality. Therefore, a paper flattening mechanism for paper printing is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a paper flattening mechanism for paper printing, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a paper printing paper flattening mechanism, comprising a conveyor for conveying printing paper, a support frame fixed on one side of the conveyor, an electric push rod fixed on one side of the support frame, a horizontal plate located on the upper side of the conveyor fixed at the push rod end of the electric push rod, and a flattening roller for flattening the paper fixed at the bottom of the horizontal plate.
[0006] The conveyor discharge end is equipped with a storage platform for temporary paper storage;
[0007] A dust removal component for cleaning the paper surface is provided on one side of the conveyor;
[0008] The dust removal assembly includes a fixed frame and a locking mechanism. The fixed frame has a limiting groove inside, and a limiting platform is fixed to the inner wall of the limiting groove. A filter screen located above the limiting platform is inserted into one side of the fixed frame.
[0009] A limiting plate is fixed to one side of the filter screen, and a locking groove is provided on one side of the limiting plate.
[0010] Preferably, the conveyor is equipped with a centrifugal fan at its bottom, and the air inlet of the centrifugal fan is connected to the air outlet of the fixed frame via a hose.
[0011] Preferably, the above-mentioned fixing brackets are in the form of two brackets, with one side of each bracket fixed to one side of the storage platform.
[0012] Preferably, the above-mentioned fixing frame has several brush bristles fixedly inserted on one side, with two brush bristles arranged opposite each other.
[0013] Preferably, the locking mechanism includes a limiting frame, the limiting frame having a sliding groove inside, and a sliding plate slidably connected to the inner side of the sliding groove.
[0014] Preferably, the above-mentioned: a locking rod is fixed to one side of the skateboard and extends through one side of the limiting frame, and a pull rod is fixed to one side of the skateboard;
[0015] When the locking rod is inserted into the lock groove, the filter screen is in the installed state; when the locking rod leaves the lock groove, the filter screen is in the disassembled state.
[0016] Preferably, one side of the limiting frame is fixed to one side of the fixing frame, and a spring is connected between one side of the sliding plate and the inner side of the slide groove.
[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:
[0018] By conveying the paper through a conveyor, multiple flattening rollers can distribute pressure more evenly, ensuring that the paper is subjected to uniform force during the flattening process and avoiding localized indentations or unevenness. The large contact area between the flattening rollers and the paper helps to flatten the paper better and improve the flattening quality.
[0019] The brush bristles effectively remove residual contaminants such as dust, paper scraps, and oil stains from the paper surface, ensuring the cleanliness of the paper before it enters the printing process. The suction generated by the centrifugal fan further enhances the cleaning effect, allowing the contaminants brushed off by the bristles to be sucked into the limiting groove in a timely manner, thus avoiding secondary contamination.
[0020] When contaminants accumulate on the surface of the filter screen to a certain extent, the filter screen can be easily removed for cleaning or replacement. Simply pull the lever to one side to compress the spring and cause the locking rod to move away from the inside of the locking groove. Workers can complete the replacement by simply pulling and releasing the lever, without complicated disassembly and installation steps, thus improving maintenance efficiency.

Example
[0030] Please see Figure 1-5 This utility model provides a technical solution: a paper printing paper flattening mechanism, including a conveyor 1 for conveying printing paper, a support frame 2 fixed on one side of the conveyor 1, an electric push rod 3 fixed on one side of the support frame 2, a horizontal plate 4 located on the upper side of the conveyor 1 fixed at the push rod end of the electric push rod 3, and a flattening roller 5 for flattening the paper fixed at the bottom of the horizontal plate 4; the push rod end of the electric push rod 3 extends out and pushes the horizontal plate 4 downward, so that the outer sides of the multiple flattening rollers 5 contact the paper, so that the multiple flattening rollers 5 flatten the paper; the discharge end of the conveyor 1 is provided with a storage platform 7 for temporary storage of paper;
[0031] A dust removal component 6 for cleaning the paper surface is provided on one side of the conveyor 1;
[0032] The dust removal assembly 6 includes a fixed frame 61 and a locking mechanism. The fixed frame 61 has a limiting groove 68 inside, and a limiting platform 69 is fixed to the inner wall of the limiting groove 68. A filter screen 67 is inserted into one side of the fixed frame 61 and is located on the upper side of the limiting platform 69. Sealing rings (not shown in the figure) are glued to both sides of the filter screen 67. The sealing rings fit against the inner wall of the fixed frame 61 to prevent dust from entering the inner side of the centrifugal fan 64 from the side of the filter screen 67.
[0033] A limiting plate 66 is fixed to one side of the filter screen 67. A locking groove 613 is opened on one side of the limiting plate 66. A centrifugal fan 64 is provided at the bottom of the conveyor 1. The air inlet of the centrifugal fan 64 is connected to the air outlet of the fixed frame 61 through a hose. There are two fixed frames 61. One side of the fixed frame 61 is fixed to one side of the storage table 7. Several brush bristles 62 are fixedly inserted into one side of the fixed frame 61. When the centrifugal fan 64 starts to work, the air inlet of the centrifugal fan 64 generates suction and delivers the suction to the inside of the limiting groove 68 inside the fixed frame 61. When the paper passes through one side of the limiting groove 68, the brush bristles 62 brush away the contaminants remaining on the surface of the paper. The two brush bristles 62 are arranged opposite each other.
[0034] The locking mechanism includes a limit frame 63, with a slide groove 612 inside the limit frame 63. A slide plate 610 is slidably connected to the inner side of the slide groove 612. Pulling down the pull rod 65 causes the pull rod 65 to drive the slide plate 610 to slide inside the slide groove 612. At the same time, the slide plate 610 compresses the spring 614. At this time, the slide plate 610 drives the locking rod 611 to leave the inner side of the locking groove 613. A locking rod 611 that moves through one side of the limit frame 63 is fixed on one side of the slide plate 610, and a pull rod 65 is fixed on one side of the slide plate 610.
[0035] When the locking rod 611 is inserted into the inner side of the locking groove 613, the filter screen 67 is in the installed state. When the locking rod 611 leaves the inner side of the locking groove 613, the filter screen 67 is in the disassembled state. One side of the limiting bracket 63 is fixed to one side of the fixing bracket 61. A spring 614 is connected between one side of the sliding plate 610 and the inner side of the sliding groove 612. Pull the limiting plate 66 to one side, and the limiting plate 66 will drive the filter screen 67 to leave the inner side of the fixing bracket 61. Then, take out a new filter screen 67 and insert it into one side of the fixing bracket 61. Then, release the pulling force of the pulling rod 65. At this time, under the elastic force of the spring 614, the locking rod 611 is pushed into the inner side of the locking groove 613. At this time, the replacement of the filter screen 67 is completed.
[0036] The model number of centrifugal fan 64 is CY180.
[0037] Working principle: To flatten the paper to be printed, simply place the paper at its input end using the conveyor 1. Under the action of the conveyor 1, the paper moves to the storage table 7. At this time, the push rod end of the electric push rod 3 extends and pushes the horizontal plate 4 downward, so that the outer sides of multiple flattening rollers 5 come into contact with the paper, and the multiple flattening rollers 5 flatten the paper.
[0038] After the paper is flattened, it will pass between the two brushes 62 and then enter the top of the storage table 7. The worker can then pick up the paper that has entered the top of the storage table 7 for printing. The bottom brushes 62 are flush with the surface of the conveyor belt of the conveyor 1, and the top brushes 62 are in contact with the top of the paper.
[0039] At this time, the centrifugal fan 64 starts to work. The air inlet of the centrifugal fan 64 generates suction and delivers the suction to the inside of the limiting groove 68 inside the fixed frame 61. When the paper passes through one side of the limiting groove 68, the bristles 62 brush away the contaminants remaining on the paper surface and, under the action of suction, suck the contaminants into the inside of the limiting groove 68 and adsorb them on the surface of the filter screen 67.
[0040] When a large amount of pollutants adsorb onto the surface of the filter screen 67, simply pull down the lever 65, causing the lever 65 to slide the slide plate 610 inside the slide groove 612. At the same time, the slide plate 610 compresses the spring 614. At this time, the slide plate 610 drives the locking lever 611 away from the inside of the locking groove 613. Then, pull the limiting plate 66 to one side. The limiting plate 66 drives the filter screen 67 away from the inside of the fixing frame 61. Then, take a new filter screen 67, insert the filter screen 67 into one side of the fixing frame 61, and then release the pulling force of the lever 65. At this time, under the elastic force of the spring 614, the locking lever 611 is pushed into the inside of the locking groove 613, thus completing the replacement of the filter screen 67.
[0041] In summary, by conveying the paper through the conveyor 1, the multiple flattening rollers 5 can distribute the pressure more evenly, ensuring that the paper is subjected to uniform force during the flattening process, avoiding local indentations or unevenness. The flattening rollers 5 have a large contact area with the paper, which helps to flatten the paper better and improve the flattening quality.
[0042] The brush bristles 62 can effectively remove residual contaminants such as dust, paper scraps, and oil stains from the paper surface, ensuring the cleanliness of the paper before it enters the printing process. The suction generated by the centrifugal fan 64 further enhances the cleaning effect, and can promptly suck the contaminants brushed off by the brush bristles 62 into the limiting groove 68, avoiding secondary contamination of the contaminants.
[0043] When contaminants accumulate on the surface of the filter screen 67 to a certain extent, the filter screen 67 can be easily removed for cleaning or replacement. Simply pull the lever 65 to one side to compress the spring 614 with the slide plate 610 and cause the locking rod 611 to leave the inside of the locking groove 613. Workers can complete the replacement by simply pulling and releasing the lever 65 without complicated disassembly and installation steps, thereby improving maintenance efficiency.
