Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a paper conveying device of a printing press. Background Art

[0002] Printing machinery is a general term for mechanical equipment such as printing presses, bookbinding machines, plate-making machines, and other auxiliary mechanical equipment. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is installed on the printing press, and then the ink is applied to the places with text and images on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed products as the printing plates. When working on a printing press, it is usually necessary to set a paper conveying device at the rear of the printing press to transmit the printed products.

[0003] At present, the common paper feeding device of printing presses is usually in the form of a conveyor belt. The printed paper is moved onto the conveyor belt and the paper is transported by the rotating conveyor belt, which is convenient for collecting the printed paper. However, this structure is relatively simple and can only realize the transmission of paper. The printed paper is transported by a conveyor belt-shaped paper feeding device. Due to the light texture of the paper, the paper is easily displaced during the transmission process, and even floats out of the paper feeding device. In addition, since the temperature of the paper is high after printing, the printed paper is directly transported and collected by the paper feeding device, resulting in the temperature of the paper not being dissipated in time. When the paper is collected and piled up, the heat accumulates inside the paper for a long time, which easily causes the paper to be deformed by heat, resulting in reduced paper quality. For this reason, we propose a printing press paper feeding device to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0018] Combination Figure 1A paper feeding device of a printing press comprises a workbench 1, a rotating shaft 2 is passed through and fixedly connected to the workbench 1, a conveyor belt 3 is arranged outside the rotating shaft 2, a vent 4 is opened outside the conveyor belt 3, a support 5 is fixedly connected to the bottom of the workbench 1, a paper feeding pipe 6 is fixedly connected to the top left side of the workbench 1, a printing press body 18 is fixedly connected to the left side of the paper feeding pipe 6, an air pump 7 is fixedly connected to the front side of the workbench 1, an upper air injection pipe 8 is passed through and fixedly connected to the left side of the air pump 7, a lower air injection pipe 9 is passed through and fixedly connected to the right side of the air pump 7, and a flattening component is fixedly connected to the top of the workbench 1.

[0019] The paper is fixed by the gantry 10, telescopic rod 11, mounting base 12, fixing seat 13, supporting shaft 14, flattening roller 15, threaded rod 16 and operating panel 17, so that the paper will not be displaced during the transmission process, thereby ensuring the safety of the paper.

[0020] Combination Figure 2 and Figure 3 The flattening assembly includes a gantry 10, a telescopic rod 11 is fixedly connected to the top of the inner wall of the gantry 10, a mounting base 12 is fixedly connected to the output end of the telescopic rod 11, fixed seats 13 are fixedly connected to the two sides of the bottom of the mounting base 12, a support shaft 14 is rotatably connected to one side of the fixed seat 13, the support shaft 14 passes through and is fixedly connected to a flattening roller 15, a threaded rod 16 passes through and is rotatably connected to the top of the mounting base 12, an operating panel 17 is fixedly connected to the top of the threaded rod 16, and the threaded rod 16 passes through and is threadedly connected to the gantry 10.

[0021] The cooling of the paper is achieved through the cooperation among the air pump 7, the upper air jet pipe 8, the lower air jet pipe 9, the air vent 4 and the paper transfer pipe 6, with high efficiency and good effect, and the paper is fully cooled.

[0022] Combination Figures 1 to 3 The lowest descending position of the flattening roller 15 is flush with the upper surface of the conveyor belt 3. There is a distance between the top of the flattening roller 15 and the mounting base 12. The conveyor belt 3 is divided into two sections. The air vents 4 of the front section and the rear section are arranged at different positions. The wind sprayed by the upper air jet pipe 8 is sprayed in the lower right direction to ensure that the paper will not circle in the paper transfer pipe 6. The output port of the paper transfer pipe 6 is almost in contact with the conveyor belt 3, ensuring that the paper is transported to the flattening device by the conveyor belt 3 as soon as it falls.

[0023] The cooperation among the air pump 7, the upper jet pipe 8, the paper transfer pipe 6 and the conveyor belt 3 ensures that the paper will definitely fall onto the conveyor belt 3. At the same time, once it falls, it will be transferred to the flattening device by the conveyor belt 3. At the same time, the lower jet pipe 9 and the air vent 4 will fully dissipate the heat of the paper.

[0024] Working principle: When in use, the user transfers the finished paper printed by the printing machine body 18 into the paper transfer pipe 6, turns on the air pump 7, and supplies air to the upper jet pipe 8. The paper is cooled once by the blowing of the gas, and the paper is blown onto the conveyor belt 3. The conveyor belt 3 immediately transfers the paper to the flattening device. At the same time, the lower jet pipe 9 works, and the ejected gas is blown onto the paper through the vent 4 to perform secondary heat dissipation on the paper. After the paper enters the flattening device, the mounting base 12 is driven down by rotating the operating disk 17. At the same time, the flattening roller 15 begins to reduce the distance between it and the conveyor belt 3, and pressure is applied to the paper, so that the paper will not be displaced by the wind during the transmission process. At the same time, the paper is flattened, so that the paper will not be displaced during the transmission process. At the same time, the paper is fully cooled, which is convenient and practical.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
