Description

A paper core feeding device for a rewinding machine

Technical field

The invention relates to a rewinding machine component, in particular to a rewinding machine paper feeding core device.

Background technique

Rewinding machines are mainly used to produce roll materials, such as gift paper rolls, toilet paper rolls, etc. With the continuous development and progress of science and technology, some rewinders that can continuously produce cored or coreless roll materials have appeared on the market. The machine greatly improves the production efficiency of roll materials.

The basic working principle of the cored web rewinding machine is that the core tube is first placed in the rewinding position, and the rewinding roller driven by the power drives the core tube to rotate. At the same time, paper, film and other materials are fed to the rewinding position. Paper, film and other materials are rolled on the core tube to complete the rewinding operation to form a roll material.

As one of the core components of the automated core web rewinder, the performance and stability of the paper core device of the rewinder play a key role in the operation of the entire rewinder. However, the paper core feeding devices of rewinders currently on the market often have the following problems:

1. The paper core feeding device of the general rewinder adopts the gravity blanking method, which restricts the freedom of movement of the paper core too little, causing the paper core to be unable to fall into the rewinding position stably, which can easily cause equipment shutdown or defective products;

2. The paper core feeding device of the general rewinder cannot be adjusted or is very inconvenient to adjust for paper cores of different lengths and diameters. In automated production with extremely high flexibility requirements, it can often only feed paper cores of one specification.
