Servo conveying mechanism for folded pull-up of infant

Abstract

The invention relates to the technical field of disposable sanitary products and in particular to a servo conveying mechanism for a folded pull-up of an infant. The servo conveying mechanism comprisesa rack, wherein a transmission assembly, a driving guide wheel, a supporting rack and a plurality of driven guide wheels are arranged on the rack, the supporting rack is strip-type and is formed by splicing mounting plates made from rigid materials, the mounting plates are 1-3 mm thick, a plurality of mounting holes are formed in each mounting plate, the driven guide wheels are arranged on the mounting plates through mounting holes, the driven guide wheels are 10-20 mm thick, round belts in closed loop states are separately arranged on the driving guide wheel and the driven guide wheels, andthe diameters of the round belts are consistent with the thicknesses of the driven guide wheels. The servo conveying mechanism avoids a phenomenon that the pull-up is inclined and wrinkled as a resultof friction in a conveying process of bonding an abandoning paste of a discontinuous crotch of the pull-up.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to a servo conveying mechanism for baby pull-up pants folded in half. Background technique [0002] Some of the existing pull-up pants are usually glued with a disposable sticker on it. After the pull-up pants are used up, they are rolled up, then fixed with the discard sticker and then thrown into the trash can, which is very convenient to use. [0003] Such as figure 1 , figure 2 As shown, when the disposable sticker is bonded to the pull-up pants, usually after the bonding of the layers of the diaper is completed, the pull-up pants 1' are folded in half in the vertical plane through the folding mechanism, and then transferred to the horizontal plane by the belt turning mechanism 2' , and then under the auxiliary guidance of the guide rod 3', the discarded stickers are attached by the discarded knife holder 4', and then enter the compacting mechanism 5' to ...

Problems solved by technology

[0003] like figure 1 , figure 2 As shown, when the disposable sticker is bonded to the pull-up pants, usually after the bonding of the layers of the diaper is completed, the pull-up pants 1' are folded in half in the vertical plane through the folding mechanism, and then transferred to the horizontal plane by the belt turning mechanism 2' , and then under the auxiliary guidance of the guide rod 3', the discarded stickers are attached by the discarded knife holder 4', and then enter the compacting mechanism 5' to compact the pull-up pants 1', wherein the pull-up pants 1 After the pull-up pants are in the horizontal plane through the belt turning mechanism 2', the guide bar 3' needs to support the discontinuous crotch of the pull-up pants 1' for auxiliary guidance to prevent the pull-up pants from retracting, which is not conducive to the later stage It is compacted to affect the flatness of the finished product. However, since the guide rod 3' is to carry out auxiliary guidance against the crotch of the pull-up pants, it will have an outward pressure on the crotch of the pull-up pants, so that the pull-up pants The pull-up pants are kept flat as a whole, which is convenient for discarding and bonding and is conducive to later compaction. However, although the guide rod 3' can lift the crotch of the pull-up pants to keep it flat and assist in guiding, it is difficult to quickly transport the pull-up pants. In the case that the friction between the guide rod and the crotch of the pull-up pants is relatively large, it is still easy to cause the crotch of the pull-up pants to tilt and wrinkle
