The disposable plaster used for the disposable sanitary product at present is usually a rubber-faced material, and only the adhesive face needs to be attached and fixed on the back waistline of the back D of the disposable sanitary product.

As shown in fig. 6, taking a manufacturing apparatus for pull-up pants as an example, a conventional manufacturing apparatus for composite sheets includes a cutting apparatus 3 'for cutting a continuously conveyed tape sheet P0' into tape pieces P1', wherein the cutting apparatus 3' includes a knife roll 31 'and a bottom roll 32' provided in correspondence thereto, and the tape pieces P1 'are adhered to an outer peripheral surface of the bottom roll of the cutting apparatus 3' and are combined with a disposable hygiene product semi-finished product S0 'conveyed from an upstream side by pressing of a pressing roll 6' with rotation of the bottom roll 32 'to form a composite sheet S1'.

Since the conveying device 2' for sucking and conveying the continuous tape sheet P0' is provided before the cutting device 3' cuts the tape sheet P0', a vacuum sucking structure is provided inside the conveying device 2 '. Since the tape pieces P1 'are located at the rear waistline position of the pull-up diaper product, the pull-up diaper product is laid down in the rear station of the pull-up diaper manufacturing apparatus, in which the front waistline is upward and the rear waistline is downward, when the tape sheet P0' is set up in the relevant process, the conveying device 2 'is usually set upside down, that is, the adsorption conveying surface F' of the conveying device 2 'is downward, and the tape sheet P0' is adsorbed on the adsorption conveying surface F 'of the conveying device 2' downward.

When the equipment is operated, negative pressure air flow is input into the conveying device 2', so that the adhesive tape sheet P0' is adsorbed at the position of the adsorption conveying surface F ', and conveying is realized, and the adhesive tape surface of the adhesive tape sheet P0' faces downwards, namely, is opposite to the adsorption conveying surface F '; however, when the air supply is cut off due to a trouble of the apparatus or maintenance stop, the bottom roller 32 'of the cutting device 3' and the air supply of the suction structure inside the conveying device 2 'are also cut off, and the tape sheet P0' is located at a position facing the suction conveying surface F 'of the apparatus, so that the tape sheet PO' falls down by gravity when the tape sheet P0 'is cut at a position right at the cutting position of the cutting device 3'. When equipment was started up again, need the manual work to pull sticky tape sheet P0' to cutting device 3' in, this kind of mode operation is inconvenient, influence production efficiency, and the most important is when cutting position when getting into cutting device 3' to sticky tape sheet P0' again fixes a position, has can't stop the cutting position that sets up before shutting down accurately and has influenced cutting effect and precision in so great degree.

And an adsorption device such as a fan is connected to the rear part of the vacuum box 23. By the suction device, the continuous sheet P0 is conveyed into the cutting device 3 while being sucked on the suction conveying surface F by the vacuum box 23.

Specifically, the rotating shaft 43 extends to the roller surface G of the bottom roller 23 along the axial direction and is parallel to the bottom roller 32, and the abutting plate 44 is mounted on the rotating shaft 45. In order to prevent the abutting plate 44 from being bonded to the continuous sheet P0, such as a self-adhesive side of a tape sheet or a non-tape sheet, after the adhesive is applied, the outer surface of the abutting plate 44 is subjected to an anti-sticking treatment, such as plasma spraying, teflon, or the like.

The side surface of one end of the rotating shaft 43, which is far away from the roll surface G of the bottom roll 32, is fixedly connected with the handle arm 42, and one end of the rotating shaft 43, which is far away from the roll surface G of the bottom roll 32, penetrates through the fixed plate 46 and is rotatably connected to the fixed plate 46, and the rotatable mode can adopt structures such as a bearing. The fixing plate 46 is fixedly connected to the cutting device 3, but it is also possible to separately fix the mounting plate to the mounting plane.

The stopper 45 is provided at an extreme position above the handle arm 42 for defining a rotational position of the handle arm 42.

In this embodiment, when the apparatus normally operates, the piston rod of the air cylinder 41 extends to contact the contact portion J of the handle arm 42, so as to push the handle arm 42 to rotate counterclockwise around the rotation shaft 43 until the handle arm 42 reaches the position of the stopper 45, and the rotation shaft 43 connected to the handle arm 42 rotates along with the rotation of the handle arm 42, so as to drive the abutting plate 44 away from the bottom roller 32 through the continuous sheet P0, specifically, the abutting plate 44 away from the outer peripheral surface 321 of the roller surface G of the bottom roller 32 through the continuous sheet P0.

When the equipment is in failure, reloading or maintenance and management, and the shutdown is required to cut off the air source, the piston rod of the air cylinder 41 retracts, the handle arm 42 descends under the action of gravity and drives the rotating shaft 43 connected with the handle arm 42 to rotate reversely, so that the abutting plate 44 is driven to be in contact with the bottom roller 32 through the continuous sheet P0, specifically, the abutting plate 44 abuts against the outer peripheral surface 321 of the roller surface G of the bottom roller 32 through the continuous sheet P0, the continuous sheet P0 is prevented from falling under the action of gravity, and therefore the continuous sheet P0 can be guaranteed to accurately stop at the cutting position arranged before the shutdown, and the production efficiency and the equipment automation level are improved.

The protrusions 61a are intermittently provided on the press roller 61, and since the sheet pieces P1 are intermittently combined with the semi-finished product S0, the protrusions 61a are used for press-combining the sheet pieces P1 with the semi-finished product S0 in a point-to-point manner.

The first path L1 further includes a conveying device 7, and the conveying device 7 is located on the upstream side of the press roller device 6. After the continuous sheet material P0 is cut into the sheet material small pieces P1 by the cutting device 3, the sheet material small pieces P1 are combined with the semi-finished product S0 on the first path L1 which is transported from the upstream side by the transport device 7 at the position of the press roller device 6, that is, the cut sheet material small pieces P1 are attached to the back surface D of the semi-finished product S0 which is continuously drawn and laid flat, and finally the composite product S1 is formed. In this embodiment, the cut tape pieces are attached to the continuously pulled and laid-flat semi-finished product of the disposable hygienic article, as shown in fig. 4.

According to the composite sheet manufacturing device, the material propping device 4 is arranged between the conveying mechanism 2 and the cutting device 3, the structure is simple, the occupied space is small, the problem that the continuous sheet P0 drops due to the fact that an air source is cut off when the equipment is stopped under the specific condition that the conveying mechanism with an inverted structure adsorbs the sheet is effectively solved, the tape sheet can be guaranteed to accurately stop at the cutting position arranged before the equipment is stopped, and therefore the production efficiency and the automation level of the equipment are improved.
