Mechanism for traversing elastic waistline

Abstract

The present invention relates to a mechanism for traversing an elastic waistline. The mechanism comprises a rack, a large bearing pedestal fixed on the rack, a plurality of adsorption plate device with adsorption plates, a driving shaft rotatably arranged on the rack, a driving disc and a plenum chamber which are fixed on the driving shaft, a groove wheel and a plurality of connecting rods; the groove wheel is provided with a guide groove for traversing the adsorption plates; and each of the adsorption plates is communicated with the plenum chamber. The mechanism further comprises a fixed groove tray and a plurality of eccentric wheel assemblies mounted on the driving disc. The groove tray is provided with a circular track having indent segments; and one end of the eccentric wheel assembly is fixedly connected to the connecting rod, while the other end is fitted to the track and slides along the track. The driving shaft drives the driving disc to rotate; during composition, an elastic layer on each adsorption plate together with the corresponding eccentric wheel assembly do rotation, opposite to the driving shaft under the action of the indent segments of the track, and are driven by the connecting rod to enable the absorption device to decelerate, so as to ensure the composition of the elastic layers to be more smooth and perfect without influencing the overall running speed of the mechanism. The mechanism for traversing the elastic waistline in the present invention has a high working efficiency, a simple structure and a longer service life.

Description

technical field [0001] The invention relates to the field of diaper production equipment, in particular to an elastic waist-changing mechanism for changing the elastic waist of diapers. Background technique [0002] Existing paper diapers have an elastic waistline, are close-fitting, easy to wear, and effectively leak-proof, and are widely welcomed. In the current production process of elastic waist diapers, in order to ensure the continuity of the material conveyed by the elastic layer during the production process, the cutting mechanism adopts interval cutting to keep the elastic from breaking, and pull the elastic when the elastic waist becomes horizontal. After breaking, carry out elastic layer compounding. Existing horizontal variable mechanism generally comprises steerable steering wheel, rotatable adsorption flat plate and knife seat, and the wheel of steering wheel is provided with supporting roller each adsorption flat plate upwards, and steering wheel is provided ...

AI Technical Summary

Problems solved by technology

Existing horizontal variable mechanism generally comprises steerable steering wheel, rotatable adsorption flat plate and knife seat, and the wheel of steering wheel is provided with supporting roller each adsorption flat plate upwards, and steering wheel is provided with the rotary drive mechanism that subsection controls the rotation of adsorption flat plate, for Ensure that the elastic layer is compounded smoothly after the elastic layer becomes horizontal. The steering wheel needs to change speed and slow down, which is easy to cause damage to the equipment and reduce the service life of the equipment. At the same time, it is difficult to achieve high-speed operation of the production line and reduce production efficiency.
