Quantitative paper delivery device

Abstract

The invention discloses a quantitative paper delivery device. The device comprises two rolling clamping elements which are arranged in pairs and close to each other. A gap between the two rolling clamping elements is used for clamping and leading out roll paper. The quantitative paper outlet device further comprises a periodic locking mechanism. The periodic locking mechanism comprises a movable element and a locking element, and the movable element and the rolling clamping elements are in linkage and do periodic motion. The movable element has a first state of moving under the action of the first acting force and a second state of moving to be matched and locked with the locking element. The movable element is driven by the rolling clamping element to do periodic motion. The movable element is periodically switched between the first state and the second state under the action of the locking element. When the leading-out end of the roll paper is pulled, the paper can be discharged in the first state, and the paper can be torn off in the second state. Therefore, quantitative paper delivery is achieved through a pure mechanical structure. Compared with an electric appliance product,cost is low, faults are not prone to happening, and product reliability and stability are better.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a quantitative paper output device. Background technique [0002] In public places or household washrooms, in order to make it easier for people to use toilet paper, a paper roll box is usually installed next to the sink or between the toilets. The inside of the paper roll box is provided with a roller, and a paper tube is sleeved on the roll. One end of the toilet paper sticks out of the roll paper box. When people use it, they pull the toilet paper out of the roll paper box, and the paper roll can be pulled to rotate around the roller. The toilet paper is continuously pulled out, and the pulled toilet paper reaches a certain length. Afterwards, the user will tear it off and use it. [0003] This kind of roll paper box has the following defects: (1) The roll paper box continuously outputs paper, often pulling out too much toilet paper, and some users do not pay attent...

Problems solved by technology

[0003] This kind of roll paper box has the following defects: (1) The roll paper box continuously outputs paper, often pulling out too much toilet paper, and some users do not pay attention to saving paper, and pull out far more toilet paper than actually needed , causing waste; (2) One end of the toilet paper needs to protrude out of the roll paper box and be exposed to the air in the bathroom, which is easily polluted by the external environment and affects the hygiene of paper towels

Although the above-mentioned paper output machine can precisely control the paper output, it is a small electrical product that requires a standing power supply. The manufacturing and operation and maintenance costs are high, and the electrical components are prone to aging and poor reliability.
