Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary napkin production equipment, specifically to a sanitary napkin forming and rolling cutting device. Background Technology
[0002] Sanitary napkins are absorbent materials, mainly made of cotton, non-woven fabric, pulp, or a combination of the above materials to form a polymer and polymer composite paper. The side design is mainly used to prevent side leakage.
[0003] During the production of sanitary napkin cores, the required patterns and thicknesses are typically achieved through rolling, simultaneously cutting the cores to the desired shape. Existing rolling cutting equipment usually includes a cutting roller and a pressure roller. The cutting roller is equipped with a cutter, and the cutting roller and pressure roller work together to cut the cores into the required shape. After cutting the sanitary napkin cores, existing rolling cutting equipment generally uses gravity discharge, where the cores fall into the discharge port below under their own weight. However, sometimes the cut cores get stuck in the cutter and cannot fall into the discharge port on their own, thus affecting the cutting of subsequent cores. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a sanitary napkin forming and rolling cutting device.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sanitary napkin forming and cutting device, comprising a frame, a cutting roller, a pressure roller, a connecting member, a negative pressure adsorption mechanism, and an air blowing mechanism. The cutting roller and the pressure roller are rotatably mounted on the frame, and are arranged vertically opposite to each other. The cutting roller has two adsorption chambers arranged vertically opposite to each other and a plurality of connecting holes communicating with the two adsorption chambers. The connecting member is movably mounted on the cutting roller and has adsorption holes and air blowing holes. The adsorption holes communicate with one of the adsorption chambers, and the air blowing holes communicate with the other adsorption chamber. The negative pressure adsorption mechanism communicates with the adsorption holes, and the air blowing mechanism communicates with the air blowing holes. The negative pressure adsorption mechanism is located above the air blowing mechanism. When the cutting roller rotates, the adsorption holes are alternately connected to the two adsorption chambers.
[0006] Furthermore, the negative pressure adsorption mechanism includes a negative pressure connecting pipe, one end of which is connected to the adsorption hole.
[0007] Furthermore, the blowing mechanism includes a blowing connecting pipe, which is connected to the blowing hole.
[0008] Furthermore, the cutting roller is located below the pressure roller.
[0009] Furthermore, the cutting roller includes a rotating shaft, a main body, and a cutting blade. The rotating shaft is rotatably mounted on the frame, the main body is located in the middle of the rotating shaft, and the cutting blade includes two cutting blades symmetrically arranged on the outer peripheral wall of the main body.
[0010] Furthermore, the connector includes two components, which are symmetrically arranged on both sides of the main body.
[0011] Furthermore, a sealing ring is provided between the connector and the side wall of the main body.
[0012] Furthermore, the bottom of the frame is provided with a discharge port.
[0013] Furthermore, the discharge port is located directly below the cutting roller.
[0014] As can be seen from the above description of the present invention, compared with the prior art, the sanitary napkin forming and cutting device provided by the present invention has the following advantages: the cutting roller is provided with two adsorption chambers arranged vertically opposite each other and multiple connecting holes communicating with the two adsorption chambers, and the cutting roller is provided with a movable connecting member, which is provided with an adsorption hole and an air blowing hole. The adsorption hole communicates with one of the adsorption chambers, and the air blowing hole communicates with the other adsorption chamber. When the cutting roller rotates, the adsorption hole is alternately connected to the two adsorption chambers, so that the cutting roller can adsorb the cotton core to be cut while blowing the cut cotton core away from the cutting roller. Specifically, the adsorption hole is connected to a negative pressure adsorption mechanism, which is used to adsorb the sanitary napkin cotton core to be cut onto the cutting roller, and the air blowing hole is connected to an air blowing mechanism, which is used to blow the cut sanitary napkin cotton core away from the cutting roller, thereby preventing the cut cotton core from getting stuck on the cutting roller and avoiding affecting the cutting of the subsequent cotton core to be cut.

The cutting roller 2 and the pressure roller 3 are rotatably mounted on the frame 1, and are arranged vertically opposite to each other. The cutting roller 2 has two adsorption chambers arranged vertically opposite to each other and a plurality of connecting holes 7 communicating with the two adsorption chambers. The connecting member 4 is movably mounted on the cutting roller 2, and has adsorption holes 41 and air blowing holes 42. The adsorption holes 41 communicate with one of the adsorption chambers, and the air blowing holes 42 communicate with the other adsorption chamber. The adsorption chambers are connected. When the cutting roller 2 rotates, the adsorption hole 41 is alternately connected to the two adsorption chambers, so that the cutting roller 2 can adsorb the cotton core to be cut while blowing the cut cotton core away from the cutting roller 2. The negative pressure adsorption mechanism 5 is connected to the adsorption hole 41. The negative pressure adsorption mechanism 5 is used to adsorb the sanitary napkin cotton core to be cut onto the cutting roller 2. The blowing mechanism 6 is connected to the blowing hole 42. The blowing mechanism 6 is used to blow the cut sanitary napkin cotton core away from the cutting roller 2, thereby preventing the cut cotton core from getting stuck on the cutting roller 2 and avoiding affecting the cutting of subsequent cotton cores to be cut.
[0020] The negative pressure adsorption mechanism 5 is located above the air blowing mechanism 6.

[0028] In use, the cotton core to be cut enters between the cutting roller 2 and the pressure roller 3. At this time, the negative pressure adsorption mechanism 5 is connected to the adsorption chamber above, thereby adsorbing and fixing the cotton core to be cut on the cutting roller 2. The air blowing mechanism 6 is connected to the adsorption chamber below, thereby blowing the cut cotton core away from the cutting roller 2 to prevent it from getting stuck on the cutting blade 23 and to ensure that it falls into the discharge port 8. When cutting cotton cores continuously, the above process is repeated continuously.
