Reversing and pitch control assembly for hygienic products

Abstract

The invention relates to a reversing and pitch control assembly for hygienic products, comprising a reversing mechanism, a pitch control mechanism and a gas distribution mechanism sleeving a spindle in order. The spindle is fixedly connected with a frame. The reversing mechanism comprises a power input wheel, a connecting shaft, a drive disc, an arc guide rail, a slider, a sucker seat, a sucker, a sucker shaft, a rocker, a first guide wheel and a cam disc fixed in the middle of the spindle. The pitch control mechanism comprises a rotating disc, an eccentric disc, a second guide wheel, a support rod, a rocker and a link. The gas distribution mechanism comprises a distribution disc, a distribution port, a negative pressure chamber and an intake port. The reversing, variable speed and gas distribution functions are integrated to a single device, thus the device uses little space of a main unit and has powerful functions and compact structure. By integrating the reversing mechanism and the pitch control mechanism, products are transferred among the suckers of different mechanisms fewer times and have a slimmer 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.
