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...

Embodiment Construction

[0019] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0020] The present invention as Figure 1-3 As shown, the reversing and pitch-changing assembly of sanitary products includes a reversing mechanism, a speed change mechanism and a gas distribution mechanism. Frame 2 is fixed and cannot rotate.

[0021] Above-mentioned reversing mechanism has connecting shaft 4, power input wheel 3, driving disc 5, arc guide rail 6, sucker 9, sucker shaft 10, sucker seat 8, rocking arm 11, first guide wheel 12 and cam disc 13. The motor 18 and the power input wheel 3 are driven by a belt 34, the power input wheel 3 and the driving disc 5 are fixed on both ends of the connecting shaft 4, the connecting shaft 4 is set on the ma...
