Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular relates to a mechanism for preventing dust and paper scraps from accumulating. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, there are cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] The rubber roller in the current printer will produce a lot of paper scraps during long-term operation. Due to the lack of effective area to collect the paper scraps generated by the friction between the paper and the rubber roller, the rubber roller sticks to the paper, causing the text and pattern on the printed paper to be missing or unclear, and reducing the service life of the printer. In view of this, we propose a mechanism that can prevent dust and paper scraps from accumulating. Summary of the invention

[0004] The object of the present invention is to provide a mechanism for preventing dust and paper scraps from accumulating, so as to solve the problems raised in the above-mentioned background technology.

[0005] In view of this, the present invention provides a mechanism for preventing dust and paper scraps from accumulating, comprising a printer, a paper cavity and a rubber roller, wherein the paper cavity is opened in the printer, and the rubber roller is rotatably installed in the paper cavity, and further comprising: Two paper scrap scattering boxes, the two paper scrap scattering boxes are symmetrically fixedly installed on the inner wall of the paper cavity and located below the rubber roller; A main board and a secondary board; the main board and the secondary board are fixedly mounted on two paper scrap scattering boxes, and a rotating roller is fixedly mounted on the top of the main board, and a wiping sleeve is fixedly mounted on the rotating roller; A cavity, wherein the cavity is provided in the main board, and wherein cotton strips are symmetrically fixedly installed in the cavity; A sliding plate is fixedly installed between the main plate and the secondary plate, and two tail ends of the sliding plate are respectively located on two paper scrap scattering boxes. A support frame is fixedly installed on the sliding plate, and a plurality of brushes are fixedly installed on the top of the support frame.

[0006] In the technical scheme, by setting the wiping sleeve, paper scrap scattering box, main board, cavity, cotton strip, rotating roller, secondary plate, sliding plate, support frame and brush, it is ensured that during the operation and rotation of the rubber roller in the printer, personnel can inject an appropriate amount of clean water into the cavity of the main board in advance, and the two cotton strips will absorb the clean water in the cavity of the main board to become moist, and then the two moist cotton strips will absorb the wiping sleeve to become moist. The wiping sleeve is also made of cotton material. When the rubber roller is running and rotating, the wiping sleeve can be driven to rotate by the rubber roller. At the same time, the wiping sleeve on the rotating roller is against the rubber roller, which can wipe the excessive dust and dirt accumulated on the rubber roller, so as to ensure that the rubber roller will not increase the friction on the paper and cause the generation of paper scraps, and even if the rubber roller is stained with The wiping sleeve on the rotating roller can also wipe the paper scraps on the rubber roller clean. At the same time, before the wiping sleeve wipes the rubber roller, there are several brushes to clean the rotating rubber roller to ensure the initial cleaning of the rubber roller. The generated paper scraps or impurities will fall on the sliding plate and will be blocked by the main plate and the secondary plate to prevent them from falling outside the two paper scrap scattering boxes. Under the action of gravity, the paper scraps or impurities on the sliding plate will slide into the two paper scrap scattering boxes, ensuring that multiple paper scrap scattering boxes are added in the printer, so that when the printer is working, the paper scraps generated by the friction between the paper and the rubber roller have an area to be scattered, which solves the problem of the rubber roller sticking to the paper, resulting in missing or unclear text and patterns on the printed paper, and at the same time increases the service life of the printer.

[0007] In the above technical solution, further, the two paper scrap scattering boxes are fixed to the inner wall of the paper cavity by a plurality of screws.

[0008] In this technical solution, the structural stability of the two paper scrap scattering boxes is ensured, and at the same time, it is convenient to disassemble and install the paper scrap scattering boxes, and it is convenient to clean the paper scraps and impurities in the paper scrap scattering boxes.

[0009] In the above technical solution, further, the main board and the secondary board are fixed to the paper scrap scattering box by a plurality of screws.

[0010] In this technical solution, the structures of the main board, the secondary board and the paper scrap scattering box are ensured to be stable, so that the main board and the secondary board can be easily removed from and installed on the paper scrap scattering box.

[0011] In the above technical solution, further, the wiping sleeve is in contact with the rubber roller.

[0012] In the technical solution, the wiping sleeve is able to wipe off the excessive dust and dirt accumulated on the rubber roller during its operation and rotation, thereby ensuring that the rubber roller does not increase the friction on the paper and cause the generation of paper scraps, thereby solving the problem of the rubber roller sticking to the paper, resulting in missing or unclear text and patterns on the printed paper, and at the same time increasing the service life of the printer.

[0013] In the above technical solution, further, both of the two cotton strips are in contact with the wiping sleeve.

[0014] In this technical solution, after ensuring that a proper amount of clean water is injected into the cavity of the main board, the two cotton strips will absorb the clean water in the cavity of the main board and become moist. Subsequently, the two moist cotton strips are absorbed by the wiping sleeve and become moist. The wiping sleeve is made of cotton material, which ensures that the wiping sleeve can wipe off the excessive dust and dirt accumulated on the rotating rubber roller.

[0015] In the above technical solution, further, the slide plate, the main plate and the secondary plate are an integrally formed structure.

[0016] In this technical solution, the structural stability of the sliding plate, the main plate and the secondary plate is ensured to ensure the normal operation of the entire device.

[0017] In the above technical solution, further, the cross section of the slide plate is an isosceles triangle structure.

[0018] In the technical solution, the top of the slide plate is ensured to be in an inclined structure. When paper scraps or impurities fall on the slide plate, they will slide into the two paper scrap scattering boxes under the action of gravity, ensuring that when the printer is working, the paper scraps generated by the friction between the paper and the rubber roller can be scattered into the two paper scrap scattering boxes for collection, thus solving the problem of missing or unclear text and patterns on the printed paper caused by the rubber roller sticking to the paper in the past, and at the same time increasing the service life of the printer. In the above technical solution, further, the plurality of brushes are in contact with the rubber roller.

[0019] In the technical solution, before the wiping sleeve wipes the rubber roller, a plurality of brushes are provided to perform the initial cleaning of the rotating rubber roller in advance to ensure that the paper scraps or impurities on the rubber roller are swept away.

[0020] In the above technical solution, further, the length of some of the brushes is 0.3-0.8 cm.

[0021] In the technical solution, it is ensured that the plurality of brushes are in a bent state against the rubber roller, thereby ensuring that the plurality of brushes can perform the initial cleaning of the rubber roller.

[0022] In the above technical solution, further, a plurality of the brushes are arranged in a matrix.

[0023] In the technical solution, a plurality of brushes can effectively clean the rubber roller.

Through the arranged wiping sleeve, paper scrap scattering box, main board, cavity, cotton strip, rotating roller, secondary plate, sliding plate, support frame and brush, it ensures that during the operation and rotation of the rubber roller in the printer, personnel can inject a proper amount of clean water into the cavity of the main board in advance, and the two cotton strips will absorb the clean water in the cavity of the main board to become moist, and then the two moist cotton strips will absorb the wiping sleeve to become moist, the wiping sleeve is also made of cotton material, when the rubber roller is running and rotating, the wiping sleeve can be driven to rotate by the rubber roller, and at the same time, the wiping sleeve on the rotating roller is against the rubber roller, and can wipe the excessive dust and dirt accumulated on the rubber roller, so as to ensure that the rubber roller will not increase the friction on the paper to cause the generation of paper scraps, and even if the rubber roller If the rubber roller is stained with paper scraps, the wiping sleeve on the rotating roller can also wipe the paper scraps on the rubber roller clean. At the same time, before the wiping sleeve wipes the rubber roller, there are several brushes to clean the rotating rubber roller to ensure that the rubber roller can be cleaned for the first time. The generated paper scraps or impurities will fall on the sliding plate and will be blocked by the main board and the secondary board to prevent them from falling outside the two paper scrap scattering boxes.
