Description

Technical Field

[0001] This invention specifically relates to the field of newspaper printing technology, and more specifically to a newspaper printing device based on visual recognition and handwriting recognition. Background Technology

[0002] Newspaper printing equipment has its unique design and function to meet the demands of high-volume, high-speed newspaper printing. A wide variety of printing equipment exists, among which the web offset printing press is the most commonly used. It uses web paper as the printing substrate, transferring the image ink from the printing plate cylinder to the paper via a blanket cylinder. The printing plate cylinder first contacts the ink, then the ink image is transferred to the blanket cylinder, which in turn transfers the image to the paper. This indirect printing method helps protect the printing plate, extends its lifespan, and enables high-speed printing.

[0003] However, in practice, it has been noted that errors are prone to occur during the printing process, such as misspellings or blurring. Therefore, printed newspapers need to be inspected to check the clarity of the text. After printing, newspapers also need to be dried. After drying, the edges of the newspapers are prone to curling. When using photoelectric sensors to scan the text, the curled newspapers can easily obscure the printed text, affecting the scanning effect and causing scanning errors. Summary of the Invention

[0004] The purpose of this invention is to provide a newspaper printing device based on visual recognition and handwriting recognition. This device uses inclined push rods arranged in a circular array to unfold the newspaper, ensuring that the text on the newspaper is not obstructed during scanning, thereby improving the handwriting recognition effect. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A newspaper printing device based on visual recognition and handwriting recognition includes a printing press, a support frame fixedly connected to the exit side of the printing press via a tripod, a handwriting scanning mechanism movably connected to the support frame, and electric push rods symmetrically fixedly connected to the top of the support frame. The printing machine includes a base, on which a printing mechanism is movably connected, and a support frame is located on the side of the printing mechanism.

[0006] As a further technical solution of the present invention, the support frame includes a base plate fixedly connected to the tripod, a top plate above the base plate, and pillars fixedly connected between the base plate and the top plate in a circular array.

[0007] As a further technical solution of the present invention, the handwriting scanning mechanism includes a movable plate located between the bottom plate and the top plate. A sliding seat corresponding to the support column is fixedly connected to the outer side of the movable plate, and the sliding seat and the support column are slidably connected. The movable plate is fixedly connected to the inner side of the photoelectric sensor.

[0008] As a further technical solution of the present invention, the bottom of the movable plate is movably connected with inclined push rods in a ring array, the end of the movable plate is movably connected with a fixed ear plate, and the fixed ear plate is fixedly connected to the movable plate. The other end of the inclined push rod is fixedly connected with an L-shaped rubber seat.

[0009] As a further technical solution of the present invention, each of the inclined push rods is provided with a limiting plate at its end, and the limiting plate is located on the side of the fixed ear plate.

[0010] As a further technical solution of the present invention, the end of the photoelectric sensor extends through the movable plate to the bottom of the movable plate, and a shielding plate is attached to the bottom of the photoelectric sensor, with guide side plates provided on both sides of the shielding plate.

[0011] As a further technical solution of the present invention, the inner side of the guide side plate is provided with a sliding groove, and two sliding columns are slidably connected in each sliding groove. The two sliding columns are symmetrically fixedly connected to both sides of the baffle plate.

[0012] As a further technical solution of the present invention, rocker arms are provided on both sides of the movable plate. One end of the rocker arm is movably connected to the base plate, and the other end of the rocker arm is movably connected to an extension rod. The side of the extension rod away from the rocker arm is fixedly connected to a sliding column on either side.

[0013] As a further technical solution of the present invention, the electric push rod is fixedly connected to the top of the top plate, and the end of the electric push rod passes through the top plate and is fixedly connected to the top of the movable plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, an electric push rod pushes a movable plate downwards. The inclined push rod, which is set at an angle, extends outwards after contacting the newspaper on the base plate, stretching the newspaper to ensure that the photoelectric sensor can accurately scan the text on the newspaper, thereby improving scanning accuracy. In this invention, when the movable plate moves downward, the inclined rocker arm moves to the side after being subjected to force. The end of the rocker arm pushes the baffle plate to move in the limiting plate through the extension rod, so that the baffle plate moves away from the bottom of the photoelectric sensor and protects the photoelectric sensor when idle. In this invention, when the baffle moves inside the guide side plate, it will drive the sliding column to move inside the slide groove. Multiple sliding columns are provided on both sides of the baffle to block the baffle and ensure that the baffle moves horizontally. Attached Figure Description

[0028] In this embodiment, the handwriting scanning mechanism 6 includes a movable plate 61 located between the bottom plate 51 and the top plate 53. A sliding seat 62 corresponding to the support column 52 is fixedly connected to the outer side of the movable plate 61, and the sliding seat 62 and the support column 52 are slidably connected. The movable plate 61 is fixedly connected to the inner side of the photoelectric sensor 63.

[0029] In this embodiment, the bottom of the movable plate 61 is movably connected with inclined push rods 64 in a ring array, the end of the movable plate 61 is movably connected with a fixed ear plate, and the fixed ear plate is fixedly connected to the movable plate 61. The other end of the inclined push rod 64 is fixedly connected with an L-shaped rubber seat.

[0030] In this embodiment, each of the inclined push rods 64 is provided with a limiting plate 65 at its end, and the limiting plate 65 is located on the side of the fixed ear plate.

[0031] In this embodiment, the end of the photoelectric sensor 63 extends through the movable plate 61 to the bottom of the movable plate 61, and a shielding plate 67 is attached to the bottom of the photoelectric sensor 63. Guide side plates 66 are provided on both sides of the shielding plate 67.

[0032] In this embodiment, the inner side of the guide side plate 66 is provided with a sliding groove 661, and two sliding posts 662 are slidably connected in each sliding groove 661. The two sliding posts 662 are symmetrically fixedly connected to both sides of the baffle plate 67.

[0033] In this embodiment, rocker arms 69 are provided on both sides of the movable plate 61. One end of the rocker arm 69 is movably connected to the base plate 51, and the other end of the rocker arm 69 is movably connected to an extension rod 68.

[0038] The working principle of this invention is as follows: When in use, the newspaper is first placed in the printing press, and the printing mechanism 2 in the printing press prints on the newspaper. After printing, the newspaper moves to the base plate 51. Then, the electric push rod 7 pushes the movable plate 61 downward. After the bottom of the tilting push rod 64 contacts the newspaper, the bottom of the tilting push rod 64 moves outward to unfold the newspaper. At the same time, the tilted rocker 69 moves to the side after being subjected to force, and the end of the rocker 69 drives the baffle plate 67 to move through the extension rod 68, so that the baffle plate 67 moves away from the bottom of the photoelectric sensor 63. The photoelectric sensor 63 scans the printed text on the newspaper and transmits the results to the computer on the printing press. The structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
