Description

High-speed printing equipment conveyer Technical Field The utility model relates to the technical field of card printing, in particular to a high-speed printing equipment conveying device. Background In continuous printing devices, a conveyor mechanism is often required to achieve continuous transport of the print carrier. However, when the conventional conveying mechanism is applied to high-speed card printing, the problems of card shaking, displacement and the like can occur. Chinese application patent CN216993621U discloses a single pass UV printer, and it includes loading platform, conveyer belt and UV printing unit, and conveyer belt and UV printing unit set up in loading platform, still are provided with the swage that is used for restricting the material removal on the loading platform, and swage is located the top of conveyer belt, is formed with the material clearance that passes through that supplies the material between swage and the conveyer belt, is formed with the printing passageway between UV printing unit and the conveyer belt. When printing, place the material in the conveyer belt, the conveyer belt transports the material to the UV and prints the subassembly, and when the material passes through the printing passageway, the UV prints the subassembly and prints the material surface. In the transportation process, the material pressing piece limits the material to the material passing gap, so that the material can be kept flat, wrinkles and offset are not easy to generate, and the subsequent printing precision is improved. The scheme has the defect that the pressing part is a fixing device and cannot be suitable for cards with various sizes. Meanwhile, the weight of the single Zhang Zhengka is lighter, and under the high-speed running state (not lower than 20 meters per minute), the conduction band has no effective measure to finish the stable transmission of the card. Disclosure of utility model In view of the deficiencies of the prior art, the present utility model is directed to a high speed printing device transport apparatus. In order to achieve the above purpose, the present utility model adopts the following technical scheme: A high-speed printing equipment conveying device comprises a belt Kong Daodai, an air suction flat plate, a negative pressure fan and a conduction band driving mechanism; The surface of the perforated conduction band is uniformly provided with a plurality of first air holes, the air suction flat plate is arranged in the perforated conduction band, the air suction flat plate is hollow, at least one side of the air suction flat plate is provided with exhaust holes, the air suction flat plate is internally provided with a plurality of negative pressure fans continuously along the conveying direction, the top surface of the air suction flat plate is uniformly provided with a plurality of airflow grooves, the airflow grooves are concave relative to the top surface of the air suction flat plate, each airflow groove is uniformly provided with a plurality of second air holes, and the conduction band driving mechanism is connected to the perforated conduction band and drives the perforated conduction band to rotate.
