Reversing and pitch-changing assembly for sanitary products

Abstract

The invention relates to a reversing pitch-changing assembly for sanitary products, which includes a reversing mechanism, a pitch-changing mechanism and a gas distribution mechanism that are sequentially set on the main shaft. Shaft, drive plate, arc guide rail, slider, suction cup seat, suction cup, suction cup shaft, rocker arm, first guide wheel and cam plate fixed in the middle of the main shaft, pitch change mechanism includes rotating disc, eccentric disc, second guide wheel , a support rod, a swing arm and a connecting rod, and the gas distribution mechanism includes a gas distribution plate, a gas distribution port, a negative pressure chamber and an air inlet. Therefore, the device takes up little space on the host computer, has powerful functions, and is compact in structure. At the same time, the synthesis of the reversing mechanism and the pitch-changing mechanism reduces the number of transfers of the product between the suction cups of different mechanisms, so that the product reduces the chance of deformation.

Description

technical field [0001] The invention relates to a reversing and torque-changing assembly, in particular to a reversing and pitch-changing assembly of sanitary products. Background technique [0002] Disposable hygienic products are composed of various hygienic substrates. Almost all composite raw materials are linear unwinding. In order to make the manufacturing process the simplest and the product size easy to be guaranteed, the materials should be composited along the unwinding and conveying direction of the wire as much as possible. , the raw materials of disposable hygiene products are compounded according to the unwinding direction of the material to make an absorber. The conveyance in which the length direction of the absorber is consistent with the unwinding direction of the material is defined as conveying according to the length direction of the product. To meet the needs of waist belts, the absorbent conveyed in the length direction should be transformed into conve...

Problems solved by technology

[0002] Disposable hygienic products are composed of various hygienic substrates. Almost all composite raw materials are linear unwinding. In order to make the manufacturing process the simplest and the product size easy to be guaranteed, the materials should be composited along the unwinding and conveying direction of the wire as much as possible. , the raw materials of disposable hygiene products are compounded according to the unwinding direction of the material to make an absorber. The conveyance in which the length direction of the absorber is consistent with the unwinding direction of the material is defined as conveying according to the length direction of the product. To meet the needs of waist belts, the absorbent conveyed in the length direction should be transformed into conveyed in the width direction, that is, the width direction of the absorbent body is consistent with the unwinding direction of the material, so that the continuous packaging film or waistline material can extend its unwinding direction and the single absorbent body Compounding, in order to produce products of the required size, there will be a speed difference between the unwinding speed of the composite packaging film or waistline and the main line manufacturing speed of the product, and the compounding of the two materials may be difficult when there is a speed difference Lead to product size deviation, wrinkling and deformation, etc.

In the production process of such disposable sanitary products, there are difficulties in changing the direction of semi-finished products and synthesizing them at the same speed.
