[0038] The main body of the device is composed of two front plates 1 placed symmetrically in the front and two rear plates 2 placed symmetrically in the rear. A plurality of brackets 4 arranged perpendicularly to the front plates 1 or the rear plates 2 are fixedly connected between the front plates 1 and the rear plates 2 to support the main frame of the device. The adjacent front plates 1 and the rear plates 2 are fixedly connected by welding.

The rear plate 2 is used to install several printing group mechanisms 300. A single printing group mechanism 300 can print one color. The printing group mechanism 300 is configured according to the number of colors required for printing patterns.

Firstly, it reduces the input of manpower, realizes automatic standardized cleaning, and ensures the quality of the pigment and the quality of the printing of the printing group mechanism 300; the pigment supply component 400 will volatilize water in the process of supplying and recovering the pigment, the cleaning recovery mechanism 500 is connected with the pigment supply component 400, and the storage part of the pigment supply component 400 can supply the waste water after cleaning to the storage part of the pigment supply component 400 according to the water shortage of the pigment for full mixing for next use, and collect and reuse the water after cleaning, thereby reducing the waste of water resources; the regulating mechanism 600 is arranged between every two printing group mechanisms 300, and adjusts the processing raw materials of sanitary products in adjacent The distance between the printing group mechanisms 300 is used to align the patterns to be printed, and can adapt to more patterns and increase the coverage of the printable surface. This is the fundamental problem solved by combining the printing component mechanisms and the adjusting mechanism 600. After the sanitary product processing raw materials pass through all the printing steps, they pass through the second guide roller 8, and the second guide roller 8 unfolds the sanitary product processing raw materials again to avoid wrinkles caused by moisture in the sanitary product processing raw materials after printing, so as to facilitate the subsequent steps. Then, the sanitary product processing raw materials pass through the third guide roller 6, and the third guide roller 6 lifts the sanitary product processing raw materials to a certain height to adapt to the feeding of the subsequent slitting and folding equipment.The angle of the power support component 200 is adjustable, and the support height can be adjusted according to the specific models of different sanitary product processing raw materials. Since the sanitary product processing raw materials are still a distance from the third guide roller 6 to the slitting and folding equipment, the power support component 200 mainly provides the power for the sanitary product processing raw materials to move to the slitting and folding equipment, avoiding the phenomenon of the sanitary product processing raw materials being pulled and broken due to being too long, and ensuring the normal transportation of the sanitary product processing raw materials. ;

[0039] Further, the printing group mechanism 300 includes an active roller 301, both ends of which are rotatably connected to the two rear plates 2 respectively, either end of the active roller 301 is rotatably connected to a driving adjustment component, the driving adjustment component is connected to the side of the rear plate 2 away from the active roller 301, the active roller 301 is rotatably connected to a matching roller 302, both ends of the matching roller 302 are rotatably connected to the two rear plates 2 respectively, the matching roller 302 is rotatably connected to a printing roller 303, both ends of the printing roller 303 are rotatably connected to a sliding annular support 306 and a threaded annular adjustment member 307 respectively, a printing module 304 is sleeved on the printing roller 303, the printing module 304 is rotatably connected to the matching roller 302, the printing module 304 is also rotatably connected to a driven roller 305, both ends of the driven roller 305 are rotatably connected to the two rear plates 2 respectively; the active roller 301 and the matching roller 302 are both adapted to the pigment supply component 400.

[0040] A pigment groove is formed between the active roller 301 and the matching roller 302, and the driving and adjusting component provides rotational power for the active roller 301. The active roller 301 drives the matching roller 302 to rotate, and the pigment supply component 400 sprays the pigment into the pigment groove. At this time, a small part of the pigment in the pigment groove is stained on the matching roller 302, and most of the pigment flows from both ends of the pigment groove into the pigment supply component 400 for reuse. The matching roller 302 can be rotated downward with the central axis of the active roller 301 as the center of the circle through the driving and adjusting component. In this way, the matching roller 302 can better align with the printing module 30 on the printing roller 303 under the premise of ensuring that the distance between the active roller 301 and the matching roller 302 remains unchanged. 4 contact, keeping the active roller 301 can stably provide pigment to the printing module 304, the threaded annular adjustment member 307 rotatably connected to one end of the printing roller 303 is used to adjust the axial movement of the printing roller 303, so that the printing module 304 can better contact with the surface of the sanitary product processing raw materials, and is used to ensure that the position of the printing on the sanitary product processing raw materials is within the requirements, the sliding annular support member 306 is used to support the rotation and axial movement of the printing roller 303, and the driven roller 305 is located below the printing roller 303, and is used to support the sanitary product processing raw materials, so that the sanitary product processing raw materials are more closely attached to the printing module 304 on the printing roller 303, thereby improving the printing effect.

[0041] Further, the drive adjustment component includes a second drive member 310, the second drive member 310 is fixedly connected to the rear plate 2, a driving gear is fixedly connected to the output end of the second drive member 310, a toothed belt is sleeved on the driving gear, a driven gear 311 is sleeved on the end of the toothed belt away from the driving gear, the driven gear 311 is fixedly connected to one end of the driving roller 301, a sleeve shaft is provided between the driven gear 311 and the rear plate 2, the sleeve shaft is rotatably connected to the end of the driving roller 301 close to the driven gear 311, a special-shaped guide piece 312 is fixedly connected to the sleeve shaft, the special-shaped guide piece 312 is slidably connected to the rear plate 2, a sliding support shaft 314 is fixedly connected to the special-shaped guide piece 312, and the sliding support shaft 314 is fixedly connected to the special-shaped guide piece 312, and the sliding support shaft 314 is fixedly connected to the matching roller 302 close to the driven gear 311. One end of the special-shaped guide piece 312 is rotatably connected to the sliding support shaft 314, and the sliding support shaft 314 is slidably connected to the rear plate 2. A protrusion 313 is provided in the middle of the top of the special-shaped guide piece 312. An adjustment limit block 315 is detachably connected to the rear plate 2 near the side of the special-shaped guide piece 312, and the adjustment limit block 315 abuts against the protrusion 313. A clamping cylinder 316 and a conventional tensioning member 317 are detachably connected to the top of one side of the rear plate 2 near the special-shaped guide piece 312, respectively. The output end of the clamping cylinder 316 is fixedly connected to one side of the protrusion 313 on the top of the special-shaped guide piece 312, and the tensioning end of the conventional tensioning member 317 is fixedly connected to the other side of the protrusion 313 on the top of the special-shaped guide piece 312.

[0042] The second driving member 310 drives the driven gear 311 through the chain, and the driven gear 311 drives the active roller 301 to rotate. The sleeve shaft rotating between the driven gear 311 and the rear plate 2 provides support for the special-shaped guide piece 312 and serves as a rotation fulcrum. The convex point 313 set on the top of the special-shaped guide piece 312 abuts against the adjustment limit block 315 installed on the rear plate 2. The adjustment limit block 315 is used to ensure that the gap between the matching roller 302 and the printing module 304 is not too large. The conventional tensioning member 317 provides downward force for the special-shaped guide piece 312 through the tension of the spring, and the pressing cylinder 316 further provides downward pressure to make the matching roller 30 2 and the printing module 304 can be in contact with each other. When the printing module 304 needs to be replaced, the limit adjustment block is removed, and the clamping cylinder 316 pulls the special-shaped guide piece 312 upward. At this time, there is a certain gap between the matching roller 302 and the printing module 304, which is convenient for replacing the printing module 304. The sliding support shaft 314 fixed on the special-shaped guide piece 312 provides rotation support for the matching roller 302. An arc-shaped through hole is opened on the rear plate 2, and the end of the matching roller 302 passes through the arc-shaped through hole. The arc-shaped through hole further limits the matching roller 302 to rotate around the central axis of the active roller 301, thereby improving the stability during operation and maintenance.

[0046] The pigment collecting tank 404 collects the pigment flowing out of the two ends of the active roller 301 and the matching roller 302, and the pigment collecting tank 404 introduces the pigment into the pigment bin 406 through the pigment guide tube 405. The pigment bin 406 has electronic components for detecting the water content of the pigment. When it is detected that the water content in the pigment bin 406 is lower than the normal standard, the waste water in the cleaning recovery mechanism 500 is filtered and then introduced into the pigment bin 406 by the water pump. At the same time, the darker color of the same color pigment raw material enters the pigment bin 406 through the pigment inlet and outlet 9 to ensure the purity of the color. The mixer (existing technology) in the pigment bin 406 accelerates the stirring. When it is detected that the water content reaches the normal standard, the water pump stops running, the mixer slows down the stirring speed, and the pigment is pumped into the spray filter 401 through the pigment pump.

The cleaning roller 505 is hollow inside, and there is a circle of rotating brushes on the annular surface. The cleaning roller 505 is rotatably connected with the rotating brush. The cleaning roller 505 makes water flow evenly onto the rotating brush. The rotating brush contacts the active roller 301 and the matching roller 302 respectively. At this time, the active roller 301 drives the matching roller 302 to rotate, and the rotating brush is respectively connected to the active roller 301 and the matching roller 302 for sliding and rotation.

The power slider 602 on the forward and reverse threaded screws 601 will move in relative or opposite directions according to the rotation direction of the rotating handle 603. When the power slider 602 moves relatively, it will drive the fourth guide roller 607 to rise. At this time, the length of the raw materials for processing sanitary products between the printing group mechanisms 300 is reduced, and on the contrary, it is increased.
