[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The conveying and adjusting device for a rotary printing press involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figure 1-5 This utility model provides a conveying adjustment device for a rotary printing press, including a body assembly 1, an adjustment assembly 2 and a conveying assembly 3. The adjustment assembly 2 is installed on both sides of the body assembly 1, and the conveying assembly 3 is sleeved inside the adjustment assembly 2.

[0021] The machine body assembly 1 includes a conveyor frame 101, a sliding groove 102, a fixing plate 103, and a slide rod 104. The sliding groove 102 is opened on the conveyor frame 101. The fixing plate 103 is symmetrically installed on the top and bottom of one side of the conveyor frame 101. The slide rod 104 is fixedly sleeved in the middle of the upper and lower fixing plates 103.

[0022] The adjusting assembly 2 includes a fixed body 201, an adjusting motor 202, a spiral push rod 203, an adjusting block 204, a rotary motor 205, and a main gear 206. The fixed body 201 is fixedly installed on the top of the conveyor frame 101. The adjusting motor 202 is nested inside, and the output shaft of the adjusting motor 202 is fixedly sleeved to the spiral push rod 203 through a coupling. The adjusting block 204 is movably sleeved on the outside of the spiral push rod 203, and one side of the adjusting block 204 is movably sleeved on the outside of the slide rod 104. The rotary motor 205 is nested inside the adjusting block 204, and the output shaft of the rotary motor 205 is fixedly sleeved to the main gear 206 through a coupling. This facilitates starting the adjusting motor 202. The output shaft of the adjusting motor 202 drives the transmission shaft to rotate, and the transmission shaft drives the spiral push rod 203 to rotate. Under the rotational pushing force of the spiral push rod 203, the adjusting block 204 can control the vertical movement of the conveyor assembly 3 and adjust the height of the conveyor assembly 3.

[0023] The conveying assembly 3 includes an upper roller shaft 301, a limiter 302, an air supply pipe 303, an exhaust port 304, an upper gear 305, a lower roller shaft 306, a lower gear 307, and an air pump 308. The upper roller shaft 301 is disposed inside the sliding groove 102, and both ends of the upper roller shaft 301 are movably sleeved between the two adjusting blocks 204. The limiter 302 is symmetrically installed on the outside of the upper roller shaft 301. The air supply pipe 303 is opened inside the upper roller shaft 301. The exhaust ports 304 are evenly distributed circumferentially on the upper roller shaft 301. The upper gear 305 is fixedly sleeved on one side of the upper roller shaft 301, and the upper gear 305 is connected to the main gear 206. The six-phase meshing mechanism includes a lower roller shaft 306 positioned below the upper roller shaft 301, equipped with a limiter 302, an air supply pipe 303, and an exhaust port 304. A lower gear 307 is fixedly fitted onto one side of the lower roller shaft 306 and meshes with the upper gear 305. An air pump 308 is fixedly installed on one side of the adjusting block 204, facilitating its activation. The air pump 308 supplies air to the interior of the upper roller shaft 301 and the lower roller shaft 306 through the air supply pipe 303. When the paper contacts the surfaces of the upper roller shaft 301 and the lower roller shaft 306, the air is blown onto the paper through the exhaust port 304, accelerating the ink drying speed.

[0024] The working principle of this utility model:

[0025] First, after the paper is printed by the rotary printing press, the paper is inserted into the upper roller 301 and the lower roller 306 and positioned between the two limiters 302.

[0026] Next, the rotary motor 205 is started. The output shaft of the rotary motor 205 drives the transmission shaft to rotate. The transmission shaft drives the main gear 206 to rotate. The main gear 206 drives the lower gear 307 that meshes with it to rotate. The lower gear 307 drives the upper gear 305 that meshes with it. The paper is conveyed to the other end under the friction between the upper roller shaft 301 and the lower roller shaft 306. At the same time, the air pump 308 is started. The air pump 308 delivers air to the inside of the upper roller shaft 301 and the lower roller shaft 306 through the air supply pipe 303. When the paper comes into contact with the surface of the upper roller shaft 301 and the lower roller shaft 306, it is blown onto the paper through the exhaust hole 304.

[0027] Finally, depending on the paper feeding situation, the adjusting motor 202 is started. The output shaft of the adjusting motor 202 drives the transmission shaft to rotate, and the transmission shaft drives the spiral push rod 203 to rotate. Under the rotational pushing force of the spiral push rod 203, the adjusting block 204 can control the up and down movement of the conveying component 3, adjust the height of the conveying component 3, and maintain appropriate tension on the paper.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
