Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary napkin production, and particularly relates to a cotton core cutting device for sanitary napkins. Background Technique
[0002] The cotton core of a sanitary napkin is the core layer for absorbing menstrual blood. It is made of highly absorbent materials (such as fluff pulp or polymer), which can quickly absorb and lock in liquids, keeping the surface dry. Its fluffy structure can reduce the sense of compression and prevent side leakage and back leakage at the same time. Some products add antibacterial components to reduce the risk of infection and ensure the hygiene and comfort of women during menstruation. When producing sanitary napkin cotton cores, the method of cutting is often used to cut and process the relatively wide cotton cores.
[0003] The cutting knives of the previous cutting devices do not have a structure that can conveniently adjust the cutting depth, and cannot conveniently cut cotton cores of different thicknesses, so the applicability during cutting is not good enough. Content of the Utility Model
[0004] Aiming at the problems in the prior art, the utility model provides a cotton core cutting device for sanitary napkins, which has a structure that can conveniently adjust the cutting depth, can conveniently cut cotton cores of different thicknesses, and has better applicability during cutting.
[0005] The technical solution adopted by the utility model to solve its technical problems is a cotton core cutting device for sanitary napkins, which includes a base, a vertical plate, a convex disk, a first tension roller, a second tension roller and a collecting roller. One side of the top of the base is provided with a vertical plate. A blanking roller, a first tension roller, a second tension roller and a collecting roller are arranged on the front side of the vertical plate through a rotating shaft, and an input shaft connected to the rotating shaft of the collecting roller is arranged on the rear side of the vertical plate.
[0006] Sliding rails are arranged at both ends near the top of the base. Sliders are sleeved in the sliding rails. A displacement plate is connected to the top of the slider. A first vertical plate is welded to one side of the top of the displacement plate, and a second vertical plate is fixedly locked by bolts to the other side of the top of the displacement plate. A bearing is arranged at one side of the top of the first vertical plate and the second vertical plate. A rotating shaft is sleeved in the bearing. A cutting knife is arranged on the periphery of the rotating shaft. A servo motor is arranged on the top of the base near the center through a fixing seat. The power output end of the servo motor is connected to a lead screw. A lead screw block is sleeved outside the lead screw, and the bottom of the lead screw block is welded to the top of the displacement plate.
[0007] By adopting the above technical solution, the cotton core of the sanitary napkin to be cut is wound around the periphery of the blanking roller. The cotton core passes through the outside of the first tension roller and the second tension roller respectively. The first tension roller and the second tension roller are used to conveniently tension the cotton core, and finally it is wound around the periphery of the collecting roller. Before winding, the cotton core is cut by the rotation of the rotating shaft and the cutting knife.
[0008] Specifically, a fixing plate is arranged at one end of the top of the base, a shaft sleeve is arranged inside the fixing plate, and one end of the screw rod is located inside the shaft sleeve.
[0009] Specifically, an extension plate is connected to one side of the first vertical plate near the top, a drive motor is installed on the top of the extension plate by bolts, and an output shaft of the drive motor is transmission-connected to one side of the rotating shaft by a coupling.
[0010] Specifically, a dust collection bin is provided near the top at one end of the first vertical plate and the displacement plate, a connecting rod is provided at the bottom of the dust collection bin, the connecting rod is connected to the first vertical plate and the displacement plate by screws, a dust collection hole is provided at one end of the dust collection bin near one end of the cutter, a reserved groove is provided through the other end of the dust collection bin, and an air outlet fan is installed on the outside of the reserved groove by screws.
[0011] By adopting the above technical solution, the dust generated by the cutter during cutting can be sucked in through the dust suction bin during operation and discharged through the air outlet end of the air outlet fan, thereby preventing dust accumulation at the cutting station from affecting subsequent cutting work.
[0012] Specifically, one end of the unloading roller, the first tension roller and the second tension roller are all connected with a convex disk, and one end of the collecting roller is provided with a limiting convex block near the edge, and the limiting convex block is provided with a scale.
[0013] By adopting the above technical solution, the material roller, the first tension roller and the second tension roller are provided with a limiting structure through the convex disk. The limiting protrusion not only provides one end of the collecting roller with a limiting structure, but the scale provided on the limiting protrusion also facilitates personnel to read the thickness of the cotton core that has been wound and collected.
