Description

Technical Field

[0001] The utility model relates to the field of absorbent article production equipment, in particular to a novel embossing roller. Background Art

[0002] Disposable absorbent articles such as baby diapers, adult diapers, pull-ups, sanitary napkins, etc. Such absorbent articles mainly include a liquid-permeable surface layer, an absorbent body, and a liquid-impermeable bottom layer that are stacked in sequence from top to bottom. The absorbent body is used to absorb and hold human excretions such as urine and menstrual blood. The liquid-permeable surface layer is used to provide a comfortable and dry feeling when contacting the body, and at the same time allows liquids to freely pass through and enter the absorbent body in the lower layer. The liquid-impermeable bottom layer is used to hold the absorbed liquid in the absorbent body, thereby preventing the absorbed liquid from soiling the wearer's pants.

[0003] During the production of absorbent articles, an embossing device is generally required. The structure of the existing embossing device, for example, Chinese Patent Application No.: 202120265469.3 discloses a sanitary product embossing device, including an embossing roller shaft, an embossing sleeve is sleeved on the outer surface of the embossing roller shaft, both left and right ends of the outer surface of the embossing roller shaft are movably connected with retaining rings through mounting bolts, a connecting shaft is inserted into the left side of the embossing roller shaft, a hole is provided in the connecting shaft, a rotating rod is movably connected between the upper and lower ends of the hole on the left side, a driving wheel and a worm gear are respectively fixed on the upper and lower ends of the outer surface of the rotating rod, brackets are respectively fixed on the upper and lower ends of the right side in the hole, a screw rod is movably connected inside the brackets, a driven wheel is fixed in the middle of the outer surface of the screw rod, a transmission belt is movably connected on the outer surface of the driven wheel and located on the outer surface of the driving wheel, threaded sleeves are respectively screwed on the upper and lower ends of the outer surface of the screw rod, a rotating shaft is movably connected to the left side of the back surface of the inner cavity of the hole, a worm is fixed on the outer surface of the rotating shaft and meshes with the worm gear, a fixing frame is fixed on the front surface of the rotating shaft, and a limit bolt is movably connected between the fixing frame and the rotating shaft. This sanitary product embossing device is convenient for installation and disassembly, facilitating the replacement and maintenance of the embossing roller shaft and is easy to use.

[0004] However, the structure of this embossing device is complex and heavy, prone to radial runout during high-speed rotation, and has a large rotational inertia, resulting in a reduction in embossing quality. Moreover, during the embossing process, the embossing is generally carried out by clamping the embossing roller and the bottom roller. After long-term use, the angle deviation is likely to occur between the two, and it is necessary to stop the machine for correction, resulting in a reduction in processing efficiency.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The embodiment of the present utility model is as follows:

[0022] Referring to Figures 1 to 5 as shown, a new type of embossing roller includes an embossing shaft 1, an embossing roller body 2 and two gear rings 3. The embossing roller body 2 is fixedly arranged on the embossing shaft 1 and is distributed in the middle part of the embossing shaft 1 axially. A plurality of bumps 4 arranged in rows and a plurality of grooves 5 arranged in rows are respectively provided on the outer peripheral surface of the embossing roller body 2. Each row of the bumps 4 and each row of the grooves 5 are alternately distributed in sequence around the outer peripheral surface of the embossing roller body 2. At least one area 6 without bumps 4 and grooves 5 is provided on the outer peripheral surface of the embossing roller body 2. Preferably, there are two areas 6. And the area 6 is strip-shaped and distributed along the circumferential direction of the outer peripheral surface of the embossing roller body 2. The two areas 6 are in an arc structure and are axially symmetrically distributed along the central axis of the embossing roller body 2. The two gear rings 3 are fixedly arranged on the embossing shaft 1 and are distributed on both sides of the embossing roller body 2 axially. Teeth (not shown in the figure) are provided on the outer peripheral surfaces of the two gear rings 3.

[0023] For this new type of embossing roller, during use, two embossing rollers are assembled in pairs, and the teeth of the gear rings 3 on the embossing rollers are meshed and connected, so that the two embossing rollers can be driven synchronously. Furthermore, the bumps 4 on one embossing roller and the grooves 5 on the other embossing roller can be accurately positioned and matched, improving the transmission accuracy, avoiding subsequent debugging, and improving the embossing efficiency. At the same time, through the pressing of the two embossing rollers, the contour amplitude of the embossed pattern is increased, and the three-dimensional effect is remarkable, thereby improving the embossing effect.

[0024] Moreover, the included angle between the connecting line a of the bumps 4 on the same row and the central axis b of the embossing roller body 2 is 15° to 60°, preferably 45°, which makes the formed embossing have high aesthetic degree and can ensure sufficient ductility during the embossing process of the concave-convex spaced arrangement, avoiding the problem of material fracture.

[0025] In this embodiment, the bump 4 has a semi-spherical structure, a cuboid structure, a frustum of a cone structure, a cylinder structure, or a frustum of a pyramid structure. Preferably, it has a semi-spherical structure. The groove 5 has a semi-spherical structure, a cuboid structure, a frustum of a cone structure, a cylinder structure, or a frustum of a pyramid structure. Preferably, it has a semi-spherical structure, so as to reduce the transverse force acting on the material, further avoid the problem of material fracture, and facilitate embossing.

[0026] Furthermore, the embossing shaft 1 includes a first shaft body 11 and a second shaft body 12. One of the gear rings 3 is arranged on the first shaft body 11, and the other gear ring 3 is arranged on the second shaft body 12.
