A kind of pulp feeding device and feeding method thereof

Abstract

The invention discloses a pulp supplying device, which includes a pulp roll, first grooves, second grooves and a frame, wherein the two second grooves are respectively fixed on the two sides of the frame; the tail ends of the two first grooves are rotationally connected with the starting ends of the second grooves through flange plate components respectively; the bottoms of the two first grooves are connected with the bottom of the frame through fourth air cylinders respectively; the fourth air cylinders drive the first grooves to rotate relative to the frame by taking the center lines of theflange plate components as axes; a shaft is arranged on the roll core of the pulp roll; the two ends of the shat move along the first grooves and the second grooves through a first bearing and a second bearing, so that the pulp roll can move among different stations.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment for disposable sanitary products, in particular to the fields of adult diapers, adult pull-up pants, pet mats, mattresses, etc., specifically a pulp feeding device. Background technique [0002] Materials for disposable hygiene products, such as pulp materials, are usually in the form of disc-shaped rolls. The feeding method generally adopts single-arm support without driving. Since the inner diameter of the pulp core is generally 3 inches (75mm), the support rod can only be 70mm in general, and the single-arm support is used. This type of structure can only be used for pulp not larger than 20 inches. Occasions where the width and weight are not greater than 500kg. In this case, if the equipment speed is high, the amount of pulp becomes larger, and the corresponding crushing device cannot achieve the required amount with 20-inch pulp, and wider pulp is required at this time.

AI Technical Summary

Problems solved by technology

[0003] When using wider pulp, the weight increases accordingly, and the length of the cantilever also increases accordingly. For example, when 20 inches is increased to 30 inches, the weight increases by 1.5 times, and the length of the cantilever also increases by 1.5 times. According to the beam under simple load Deformation calculation, at this time, the amount of deformation (maximum deflection) is proportional to the weight, and is proportional to the third power of the cantilever length, and the corresponding deformation is increased to 5 times (1.5 to the 4th power), which is difficult to meet the use requirements.
