The present invention relates to a pull-out braking device for eco-friendly paper cushioning material, and more specifically, to a pull-out braking device for eco-friendly paper cushioning material that allows paper cushioning material mounted in a stored state to be pulled out at a constant length and tension along the width direction. It's about.

Generally, in the process of packaging one or more items in a container for transport, void-filling cushioning products are usually placed in the transport container along with the items, and voids around the items in the container are used to prevent or minimize movement during the transport process. Fills a space partially or completely.

As the void filling cushioning materials described above, plastic foam peanuts, plastic bubble wrap, airbags, etc. are typically used.

Recently, paper cushioning material has been widely used as an eco-friendly packaging material even though it is somewhat expensive. Such paper cushioning material is supplied in a roll-shaped form using paper material. When the user pulls it with a certain force, the honeycomb formed during production is used. It is pulled out as if it is inflated with a shape or a certain pattern appearing, so that it cushions the product when it is packaged.

However, in the case of a product made with a paper cushioning material wound around a core shaft, the paper cushioning material and the core shaft rotate together when pulled out, so it is difficult for the paper cushioning material, which follows the width direction and has a predetermined length, to be pulled out to a constant length. However, there was a disadvantage that it was not easy to withdraw while applying a certain tensile force.

The purpose of the present invention is to install a center roll with paper cushioning material wound in close contact with the core shaft while the position of the core shaft is fixed inside the main body, and when the paper cushioning material is pulled, the center roll is fixed to the center roll. The present invention provides a pull-out braking device for eco-friendly paper cushioning material that rotates independently of the mandrel and allows the paper cushioning material to be pulled out along a certain length and tension.
