Technical Field

[0001] The utility model relates to the technical field of printing machine equipment, in particular to a transmission structure of a flexographic printing machine. Background Art

[0002] The flexographic printing machine uses a flexible printing plate and prints by transferring ink through an anilox roller. It is a type of relief printing process, referred to as flexographic printing. The image and text part of the flexible printing plate is raised. During printing, the anilox roller evenly applies a certain thickness of ink layer on the image and text part of the printing plate, and transfers the ink layer of the image and text part to the surface of the substrate to form a clear image and text.

[0003] The structure of the transmission mechanism of the printing roller, plate roller and anilox roller in the flexographic printing machine in the prior art is the main transmission structure of the flexographic printing machine. The transmission mechanism of the printing roller, plate roller and anilox roller of the upper paper-feeding flexographic printing machine disclosed in the patent publication number CN209566625U can reasonably simplify the structure of the transmission mechanism of the printing roller, plate roller and anilox roller of the upper paper-feeding flexographic printing machine, and facilitate the installation and layout of the transmission mechanism of the printing roller, plate roller and anilox roller of the upper paper-feeding flexographic printing machine.

[0004] However, the above patent still has certain drawbacks. When adjusting the tension of the synchronous belt through the tension wheel, the tension wheel adjustment still needs to be manually adjusted, which makes the adjustment of the tension of the synchronous belt inconvenient and affects the convenience of use. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transmission structure of a flexographic printing press, comprising a transmission mechanism body and a tension adjustment mechanism, the transmission mechanism body is equipped with a tension adjustment mechanism, the tension adjustment mechanism comprises an adjusting cylinder and a tensioning wheel, a fixing plate is fixedly installed on the right side of the transmission mechanism body, the adjusting cylinder is fixedly installed on the bottom end of the fixing plate, the output end of the adjusting cylinder is fixedly connected with a supporting plate, the top end of the supporting plate is fixedly connected with an adjusting rack, a fixing frame is fixedly installed on the right side of the transmission mechanism body, a transmission shaft is rotatably installed on the fixing frame, the transmission shaft is rotatably connected to the right end of the transmission mechanism body, a transmission gear is fixedly sleeved in the middle of the transmission shaft, and the transmission gear is meshed with the adjusting rack, two groups of connecting strips are fixedly sleeved on the transmission shaft, the two groups of connecting strips are distributed on the left and right sides of the transmission gear, connecting shafts are fixedly installed on both ends of the tensioning wheel, and the tensioning wheel is rotatably installed on the two groups of connecting strips through the connecting shaft.

[0008] Preferably, a protective cover is detachably mounted on the right side of the transmission mechanism body.

[0009] Preferably, a supporting plate is fixedly connected to the front end of the fixing frame, the left end of the supporting plate is fixedly connected to the right end of the transmission mechanism body, and a notch is provided at the rear end of the supporting plate, and the adjusting rack slides through the notch.

[0010] Preferably, an observation window is fixedly provided on the protective cover.

[0011] Preferably, ribs are fixedly connected between the upper and lower ends of the fixing frame and the right end of the transmission mechanism body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when in use, when it is necessary to adjust the tension of the synchronous belt, by starting the adjusting cylinder, the adjusting cylinder pushes the adjusting rack upward through the supporting plate, so that the adjusting rack drives the transmission shaft to rotate clockwise through the transmission gear, and the transmission shaft drives the connecting strip plate to rotate clockwise, so that the connecting strip plate drives the tensioning wheel to apply pressure to the synchronous belt, thereby increasing the tension of the synchronous belt; conversely, the adjusting rack moves downward, and the transmission gear rotates counterclockwise, so that the connecting strip plate drives the tensioning wheel to gradually move away from the synchronous belt, thereby reducing the tension of the synchronous belt, thereby realizing automatic adjustment of the tension of the synchronous belt. Except for the installation of the tensioning wheel on the transmission mechanism body, the other specific structural components and working principles have been described in detail in the patent disclosed by Patent Publication No. CN209566625U, so they will not be repeated here, so that the adjustment of the tension of the synchronous belt can be more convenient and the convenience of use can be improved.
