Description

Technical Field

[0001] This utility model relates to the field of flat printing rollers, and more particularly to a durable flat printing roller. Background Technology

[0002] Flatbed printing rollers are one of the key components used in offset printing (such as offset printing, flexographic printing, etc.). They are responsible for transferring ink, printing patterns, and impression during the printing process.

[0003] Existing technologies, such as the utility model patent with publication number CN207207370U9, disclose a printing roller for a printing machine. This patent uses a shell, with an unwinding roller and a rewinding roller rotatably connected inside the shell. The printing roller is rotatably connected inside the shell and located between the unwinding roller and the rewinding roller. The printing roller includes an inner roller body and several printing rings with patterns engraved on their outer surfaces. The printing rings are fitted onto the inner roller body and are circumferentially fixed to the inner roller body. One end face of the printing ring has an annular groove, and the other end face has a raised positioning protrusion. The positioning protrusion of one of two adjacent printing rings can be engaged into the annular groove of the other printing ring. Both ends of the inner roller body are screwed with locking rings. The outer surfaces of the printing rings at both ends are flat, and the locking rings can abut against the corresponding printing rings. This utility model has the advantage of convenient printing pattern replacement.

[0004] The inventors discovered in daily use that existing technologies require maintenance of rollers after prolonged use, necessitating the application of a protective emulsion to the roller surface. However, current techniques involve manual application of the protective emulsion, which can lead to uneven application, with some areas receiving too much or too little coverage. This affects the protective effect on the roller and may even cause printing quality problems. Furthermore, uncleaned roller surfaces may retain ink, dust, grease, or other impurities, which can react with the protective emulsion, affecting its even application and effectiveness, and reducing its protective capacity.

[0014] Preferably, a lever is fixedly connected to the upper surface of the baffle, and the lever has a rectangular cross-section.

[0015] The effect achieved by the above components is that when it is necessary to move the baffle, the lever can be moved directly, and the lever drives the baffle to move, making it more convenient to move the baffle.

[0016] Preferably, the cleaning ring has a circular cross-section and is a sticky rubber ring.

[0017] Preferably, a plurality of the fixing rods are evenly distributed on the auxiliary box, and the fixing rods are stainless steel rods.

[0018] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting during use.

[0019] Compared with related technologies, the durable flat printing roller provided by this utility model has the following beneficial effects:

[0020] This invention provides a durable flat printing roller. By incorporating an auxiliary structure, it addresses the issue that existing technologies require rollers to be maintained after prolonged use by applying a protective emulsion to their surface. However, this process is typically done manually, leading to uneven application, with some areas receiving too much or too little emulsion. This affects the roller's protective effect and can even cause printing quality problems. Furthermore, uncleaned roller surfaces may retain ink, dust, grease, or other impurities, which can react with the protective emulsion, affecting its uniformity and effectiveness, and reducing its protective capacity. This device facilitates both convenient cleaning of the roller and easy application of protective emulsion. Attached Figure Description

[0031] In the embodiments of this utility model, please refer to Figures 1 to 6The auxiliary structure 3 includes an auxiliary ring 306, which is rolletably connected to the roller 2. An auxiliary shell 307 is rolletably connected to the arc surface of the auxiliary ring 306. The arc surface of the auxiliary shell 307 has several slots 310. A connecting frame 309 is fixedly connected to the arc surface of the auxiliary shell 307. An auxiliary box 301 is fixedly connected to the arc surface of the connecting frame 309. Two slide bars 311 are slidably connected to the inner wall of the auxiliary box 301. A baffle is fixedly connected to the side of the two slide bars 311 that are close to each other. 308, baffle 308 is slidably connected to auxiliary box 301, one end of baffle 308 is fixedly connected to iron strip 314, the inner wall of auxiliary box 301 is fixedly connected to magnetic strip 313, a number of fixing rods 302 are fixedly connected to one side of auxiliary box 301, the end of fixing rod 302 away from auxiliary box 301 is fixedly connected to fixing plate 303, the side of the number of fixing plates 303 that is close to each other is fixedly connected to connecting shell 304, and the inner wall of connecting shell 304 is fixedly connected to cleaning ring 305. When protection of roller 2 is required, the auxiliary box 301 is moved. The auxiliary box 301 moves the connecting frame 309, which in turn moves the auxiliary shell 307. The auxiliary shell 307 moves the auxiliary ring 306, the auxiliary box 301 moves the fixing rod 302, which in turn moves the fixing plate 303. The fixing plate 303 moves the connecting shell 304, which in turn moves the cleaning ring 305. Then, both the cleaning ring 305 and the auxiliary ring 306 are placed on roller 2, and the cleaning ring 305 cleans roller 2. After the protective emulsion is applied to the roller 2 by the auxiliary ring 306, when emulsion injection is needed, the baffle 308 is pulled to move. The baffle 308 drives the slider 311 to slide on the inner wall of the auxiliary box 301, then the magnetic strip 313 separates from the iron strip 314, and then emulsion is injected into the auxiliary box 301. The protective emulsion then enters the auxiliary shell 307 through the connecting frame 309 and the slot 310. The auxiliary shell 307 then applies the protective emulsion to the roller 2 for protection. The auxiliary box 301 is equipped with two springs 315, and the two ends of the springs 315 are fixedly connected to the slider 311 and the auxiliary shell 307, respectively. When the baffle 308 is opened, the slider 311 drives the spring 315 to stretch. After use, the baffle 308 is released and the spring 315 retracts, driving the baffle 308 to return to its original position. The auxiliary box 301 is fixedly connected to a limit rod 316, and the spring 315 is sleeved on the arc surface of the limit rod 316.

Several fixing rods 302 are evenly distributed on the auxiliary box 301. The fixing rods 302 are made of stainless steel. The stainless steel material increases the service life of the fixing rods 302 and prevents them from rusting during use.

[0032] The working principle of the durable flat printing roller provided by this utility model is as follows: When the roller shaft 2 needs protection, the auxiliary box 301 is pulled to move. The auxiliary box 301 drives the connecting frame 309 to move, the connecting frame 309 drives the auxiliary shell 307 to move, the auxiliary shell 307 drives the auxiliary ring 306 to move, the auxiliary box 301 drives the fixing rod 302 to move, the fixing rod 302 drives the fixing plate 303 to move, the fixing plate 303 drives the connecting shell 304 to move, and the connecting shell 304 drives the cleaning ring 305 to move. Then, the cleaning ring 305 and the auxiliary ring 306 are both put on the roller shaft 2. Then, the cleaning ring 305 cleans the roller shaft 2. After cleaning, the auxiliary ring 306 applies protective emulsion to the roller shaft 2. When emulsion injection is needed, the baffle 308 is pulled to move. The baffle 308 drives the slide bar 311 to slide on the inner wall of the auxiliary box 301. Then, the magnetic strip 313 separates from the iron strip 314, and then the auxiliary box 301... 01. The protective emulsion is injected internally, and then enters the auxiliary shell 307 through the connecting frame 309 and the slot 310. The auxiliary shell 307 then applies the protective emulsion to the roller 2 for protection. When the baffle 308 is opened, the slide bar 311 drives the spring 315 to stretch. After use, the baffle 308 is released, the spring 315 retracts, and the baffle 308 returns to its original position. The limiting rod 316 can limit the spring 315 to prevent deformation during use and improve efficiency. The lifespan of spring 315 is extended. Limiting rod 316 can limit slide bar 311 to prevent it from deviating during use, thus improving the stability of slide bar 311. When it is necessary to move baffle 308, the lever 312 can be moved directly, which drives baffle 308 to move. Lever 312 makes moving baffle 308 more convenient. Stainless steel material can increase the lifespan of fixing rod 302 and prevent it from rusting during use.
