Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a staggered cutting device for segmenting toilet paper strips. Background Art

[0002] Toilet paper is mainly used for people's daily hygiene and is one of the indispensable types of paper for the people. In order to make toilet paper soft, mechanical methods are usually used to make wrinkles on the paper to increase the softness of the toilet paper. There are many raw materials for making toilet paper, and commonly used ones are natural and pollution-free raw materials such as cotton pulp, wood pulp, bamboo pulp, and straw pulp. Toilet paper requires no toxic chemicals, no raw materials that are irritating to the skin, and no mold, virus, or bacterial residues. In the production process of toilet paper, toilet paper is produced as a whole sheet, and then the toilet paper needs to be cut, rolled up, and other processes. The existing cutting method is mostly manual cutting, which not only has poor cutting efficiency, but also has certain safety hazards and low practicality.

[0003] The existing public technology discloses a cutting device for cutting cylindrical toilet paper with publication number CN212241205U, which effectively improves cutting efficiency, reduces the occurrence of safety hazards caused by manual cutting, and improves practicality; it includes a connecting plate, two groups of material rollers, a first connecting frame, a mounting frame and a cutting knife, and a first connecting rod is provided on the left front side, left rear side, right front side and right rear side of the bottom end of the connecting plate, the two groups of material rollers are located on the left and right sides of the connecting plate respectively, the cylindrical toilet paper is transported through the two groups of material rollers, and the connecting plate is located below the toilet paper, and a second connecting rod is provided on the left front side, left rear side, right front side and right rear side of the bottom end of the first connecting frame, and a hydraulic telescopic rod is provided on the left front side, left rear side, right front side and right rear side of the top end of the mounting frame, and the top ends of the four groups of hydraulic telescopic rods are connected to the bottom end of the first connecting frame, and multiple groups of cutting knives are installed on the mounting frame.

[0004] Although the above patent uses multiple sets of cutting knives to cut toilet paper, which improves the cutting efficiency, there are still some shortcomings in its use. First, the cutting knife used in the patent is a fixed structure and cannot be flexibly adjusted. The cutting size of the toilet paper cannot be adjusted according to needs, and it is not convenient to replace and maintain the cutting knife when it is damaged. Secondly, the patent lacks a structure to press the toilet paper before cutting. Direct cutting of the toilet paper is prone to deviation, affecting the cutting effect. For the problems in the relevant technology, no effective solution has been proposed so far. Utility Model Content

The dust caused by the cutting of toilet paper is sucked into the water tank 2. When the cutting size of the toilet paper needs to be adjusted, the first bidirectional screw 25 is driven to rotate by starting the motor 17, and then the threaded sleeve 23 is driven to move. The movement of the threaded sleeve 23 drives the two cutting knives 13 to move toward or relative to each other, thereby adjusting the cutting size of the toilet paper, thereby improving the applicability of the device. By adopting a structure in which the cutting knife 13 and the threaded sleeve 23 are slidingly connected, when the cutting knife 13 is damaged and needs to be replaced, the cutting knife 13 can be removed by turning the nut and then pulling out the stud 22, thereby improving the convenience of using the device.
