Disclosed in the present invention is a paper towel dispenser for preventing paper roll sagging, comprising a casing and paper pressing mechanisms, wherein the casing comprises a base shell and surface covers arranged at the front side of the base shell, each surface cover and the base shell forming a paper loading cavity used for placing a paper roll, the paper loading cavity being provided with a first paper outlet located on the surface cover; and at least one of a front inner side and rear inner side of each paper loading cavity is provided with a paper pressing mechanism, the paper pressing mechanism being located above the first paper outlet. During use, a paper roll is vertically placed in a paper loading cavity, and the paper is pulled out through the first paper outlet at the front side, thereby achieving center-pull paper dispensing. The present invention uses the paper pressing mechanism to press and fix the upper portion of the paper roll from the front to the rear, so as to prevent the paper roll from sagging when only a small amount of paper is left at the end of use, thereby solving the problem of the upper portion of a center-pull paper roll sagging downwards and clumping together when only a small amount of paper is left at the end of use due to the gravity, a reduction in the arch strength as the paper roll thins, or pulling of the paper, making it easy to tear or difficult to pull out.

A tangential direction of the periphery of each tissue outlet wheel (300) close to the central axis of the tissue outlet port (110) shares an identical direction with an extending direction of the tissue outlet channel. The driving assembly (500) is configured to drive at least one of the plurality of tissue output wheels (300) to rotate. When in use, the tissue passes through the tissue outlet channel surrounded by the plurality of tissue outlet wheels (300) while passing through the tissue outlet port (110), and the peripheries of the tissue outlet wheels (300) abut against the tissue. When the tissue is discharged, the driving assembly (500) is configured to drive the tissue outlet wheel (300) to rotate, so as to in turn drive the tissue to move along the tissue outlet channel, so that the tissue is automatically output from the tissue outlet port (110). Then a number of rotating turns of the tissue outlet wheels (300) driven by the driving assembly (500) is adjusted according to a tissue outlet length of the required tissue, thus solving the problems of easy tissue breakage, tissue blockage and the like caused by manual tissue extraction.
