The primary function of a paper roll lifter is to hold the paper roll in place and allow users to easily tear off a sheet without having to touch the dirty or contaminated part of the roll.
There are different types of paper roll lifters:
1. Spring-loaded: A spring mechanism is used to keep the roll in place. When a sheet of paper is pulled, the spring compresses, and the next sheet is lifted up, ready for use.
2. Lever or mechanical: These models often have a lever or a simple arm that rotates when the paper is pulled, lifting the next sheet into position.
3. Roll-over or gravity-fed: In these dispensers, the weight of the paper pulls the next sheet down, making it easier for the user to tear off a piece.
4. Smart or touchless: Some modern designs use infrared sensors or motion detection to dispense paper without touching the roll, providing a more hygienic experience.
5. Wall-mounted or freestanding: Paper roll lifters can be mounted on walls or placed on countertops, depending on the space available and convenience.
Overall, the purpose of a paper roll lifter is to make daily tasks like cleaning up more convenient and hygienic by keeping the paper organized and easily accessible.
