Double-purpose rewinding machine for preparing cored toilet paper and coreless toilet paper and method thereof

Abstract

The invention provides a double-purpose rewinding machine for preparing cored toilet paper and coreless toilet paper and a method thereof. The rewinding machine comprises an upper rewinding roller, a lower rewinding roller, a rewinding compression roller and a paper tube core feed mechanism, wherein the upper part of the lower rewinding roller is provided with a plurality of double-purpose guide plates; the double-purpose guide plates are used for roll set at the time of winding the coreless toilet paper and leading-in of a paper tube core at the time of winding the cored toilet paper; the lower rewinding roller is provided with a plurality of grooves capable of accommodating the double-purpose guide plates; and the double-purpose guide plates can be lifted properly from the grooves of the lower rewinding roller under the condition of being driven by a second driving mechanism at the time of rewinding the coreless toilet paper, thus peaks at the front ends of the double-purpose guide plates can contact with the surface of the upper rewinding roller. In the invention, a double-purpose guide plate structure is additionally arranged at the upper part of the lower rewinding roller skillfully, and the lifting and descending of the front ends of the double-purpose guide plates in the grooves of the lower rewinding roller are utilized, thus being capable of reliably and fast realizing the rewinding of the two types of toilet paper, improving the production efficiency, producing the cored toilet paper and coreless toilet paper at the same time only by one machine for manufacturers, and reducing the production costs.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a rewinder and a method for processing thin strips such as toilet paper. Background technique [0002] Existing rewinding machines for processing thin strips such as toilet paper generally include an upper rewinding roller, which is used to drive the rewound toilet paper base paper from upstream to downstream (the upstream and downstream generally refer to the direction along the In the feeding direction of toilet paper base paper, the rear part between the axis lines of the upper and lower rewinding rollers is upstream, and the front part, that is, the part of the rewinding area is downstream); the feed that rotates in the same direction as the upper rewinding roller The lower rewinding roller, and an adjustable gap is formed between the lower rewinding roller and the upper rewinding roller, and the rewound toilet paper base paper passes through the gap along the...

AI Technical Summary

Problems solved by technology

The rewinding machine composed of this structure can only effectively cooperate with auxiliary devices such as the corresponding paper core supply mechanism or coreless winding mechanism to realize a single type of processing method for cored toilet paper and coreless toilet paper, making paper products Processing manufacturers need to be equipped with multiple corresponding equipment to process and produce cored paper rolls and coreless paper rolls respectively, which not only increases manufacturing costs, but also requires a larger processing plant area

Especially for the existing coreless toilet paper rewinding machine, when it is converted to cored paper roll rewinding, its auxiliary device needs to be removed, the workload is heavy, and high-precision and high-demand debugging and calibration are required to be reinstalled. , causing long downtime and affecting production efficiency
