Roll-paper drawing device

Abstract

The invention relates to a paper towel extracting device, which comprises a casing with a paper towel outlet, a rotating shaft, a motor, a torque sensor and a controller arranged inside the casing, and a pressing mechanism arranged at the paper towel outlet; the rotating shaft and the torque The input end of the sensor is in contact, and the torque sensor senses the torque brought by the rotating shaft to obtain a trigger signal and transmit the trigger signal to the controller. The controller controls the motor to rotate and output paper towels according to the trigger signal, and controls the pressing mechanism to compress the paper towels. The paper towel extracting device of the present invention triggers the extraction of paper towels through a torque sensor, and sets a preset paper towel extension length to avoid excessive waste of paper towels. After the paper towels stop outputting, it will automatically compress the paper towels so that the user can tear away the paper towels , Integrating the sending and stopping of paper towels into the action of people taking away paper towels, no other redundant operations are required, and the problem of cross-infection caused by multiple people touching the paper pumping machine is avoided.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a paper towel extracting device. Background technique [0002] Toilet paper, usually referred to as paper towels, is mainly used for daily hygiene in people's lives, and is one of the indispensable paper types for the people. In order to make toilet paper soft, mechanical methods are usually used to wrinkle the paper to increase the softness of the toilet paper. There are many raw materials for making toilet paper, and natural and non-polluting raw materials such as cotton pulp, wood pulp, bamboo pulp, and straw pulp are commonly used. Toilet paper requires non-toxic chemicals, no raw materials that are irritating to the skin, and no residues of mold, virus, and bacteria. Toilet paper is characterized by strong water absorption, no pathogenic bacteria (e. coli and other pathogenic bacteria are not allowed), soft and thick paper with no holes, uniform wrinkle, uniform color, and...

Problems solved by technology

Although the paper pumping machine with this structure solves the problem of wetting unused paper towels, when the paper pumping machine with this structure breaks the paper towels, the paper towels are easily broken between the conveying roller and the pressure roller, so that the paper towel machine cannot normally extract the paper towels , and the paper towel machine also needs to touch the button by hand, and there are also health and safety problems, so it needs to be improved
