[0002] The non-woven fabric industry has made great progress in recent years. The application volume in sanitary absorbent materials, medical materials, and transportation textile materials has increased significantly. The large demand for non-woven fabrics has led to the continuous updating and improvement of non-woven fabric manufacturing equipment. In the conventional production of tube wet wipes, more than 90% are completed through secondary processing, that is, the required products are rewound, cut according to size, and then filled and liquid is added. The quantity control is difficult to support. (Raw material spunlace non-woven fabric) is filled and liquid is added upright to allow it to penetrate naturally. The phenomenon that the periphery is wet and the center is not wet often occurs. This brings troubles to the production of tube wet wipes. Too much is too wet, and too little is dry in the middle.

The shaft receiving station of the shaft receiving and retaining groove is disposed at the outlet of the mandrel transmission channel, and a shaft retaining mechanism 17 is disposed at the outlet of the mandrel transmission channel.

[0024] The following cloth blowing mechanism includes a cloth supporting plate arranged between the slitting mechanism and the rewinding mechanism, a following cylinder 7 is arranged below the cloth supporting plate, a blowing pipe 6 arranged parallel to the rewinding roller is arranged on the side of the cloth supporting plate facing the rewinding roller, and an air hole for blowing air toward the upper side is opened on the blowing pipe.

[0025] A coil pressing mechanism 19 is arranged above the material pushing mechanism. The pressing mechanism comprises a material pressing swing arm driven by a cylinder, and a pressing roller is arranged at the free end of the material pressing swing arm.

[0026] The pushing mechanism comprises a pushing frame driven by a pushing cylinder, and the pushing frame is installed on a linear guide rail.

[0027] The slitting mechanism comprises a fixed slitting bottom knife 8 and a movable upper slitting knife 9. A linear guide rail and a slide block mounted on the linear guide rail are arranged below the slitting bottom knife, and the upper slitting knife is connected to the slide block.

[0028] The shaft grasping and pushing mechanism comprises a pushing frame corresponding to the core shaft transmission channel and driven by the shaft transporting and pushing cylinder 14. A vertical grasping cylinder 15 is mounted on the pushing frame, and a claw for grasping the core shaft is provided at the lower end of the vertical grasping cylinder.

[0029] Humidification principle: The first step is that the liquid on the glue roller and the anilox roller move relative to each other. After squeezing out the excess liquid, a small amount of liquid will remain in the mesh of the anilox roller. The non-woven fabric sticks to the anilox roller. When the non-woven fabric wraps the mandrel, the pressure roller presses the fabric and the mandrel. At this time, the rewinding starts, and the fabric rolls up due to friction between the two rollers, so that the liquid on the anilox roller is transferred to the non-woven fabric, forming online humidification. As long as the machine does not stop, the humidification will not stop, so there will be no phenomenon of wet and dry.

[0030] After the rewinding reaches the finished roll diameter, the pressing swing arm is lifted, and the pushing mechanism pushes the rolled roll out to between the two tail rollers and drops it into the designated position.

[0031] The shaft-jointing retaining groove on the shaft-jointing cylinder falls into the mandrel, which falls through the shaft-jointing cylinder, placing the mandrel down between the rewinding roller and the anilox roller to press the cloth.

[0032] At this time, the slitting mechanism starts to work, and the upper slitting knife moves to cut the flat fabric at one time.

[0033] The working principle of the follow-up cloth blowing mechanism is: the air blows up the head of the cut cloth, so that it turns over and wraps the core shaft, and the coil pressing mechanism presses down to carry out the next step of rewinding operation.

[0034] Core pulling principle: After the finished roll falls into the designated position between the two tail rollers, the lifting rod driven by the lifting cylinder lifts the two ends of the core shaft, and the core shaft does not move. The push plate, driven by the driving mechanism, starts to withdraw the roll from the core shaft. The withdrawn roll will be transported to the designated position through the conveying mechanism in turn. The process includes an online inspection process. Those that do not meet the standards need to be discarded or quantitatively replenished.

[0035] After the mandrel of the exiting coil is grabbed by the grabbing mechanism, it is pushed to the entrance of the mandrel transmission channel, and then transmitted to the exit by the mandrel transmission channel, where it is blocked by the shaft blocking mechanism, which can be a baffle driven by a cylinder. When the finished coil is pushed away, the shaft blocking groove connected to the shaft connecting cylinder is just at the exit, the shaft blocking cylinder is retracted, the baffle is opened, and a mandrel falls into the shaft blocking groove, entering the next cycle.
