Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] It should be noted that the paper towels described in the following embodiments are all stacks of paper towels, and the composition of the added cleaning liquid is not limited.

[0034] Example 1

[0035] refer to Figures 1 to 6 , a paper towel humidifying device, comprising at least two conveyor belts 4, a frame 1 and a humidifying unit 3 arranged on the frame 1; the conveyor belt 4 is used to input multiple sections of paper towel stacks a arranged in a row, and the humidifying unit 3 is arranged above the conveyor belt 4, and comprises a liquid storage tank 2 for storing cleaning liquid, a spraying mechanism 31 for adding cleaning liquid to the paper towel stack a, and a quantitative mechanism 32 for connecting the liquid storage tank 2 and the spraying mechanism 31; the spraying mechanism 31 is slidably connected to the frame 1 to move horizontally to just above each conveyor belt 4; the spraying mechanism 31 is composed of a plurality of nozzles 311 arranged in a row, and the plurality of nozzles 311 correspond one to one to the paper towel stacks a; a horizontal driving mechanism 33 is provided on the frame 1 for driving the spraying mechanism 31 to move horizontally.

[0036] It should be noted that, in this embodiment, there are two conveyor belts 4, namely the first conveyor belt and the second conveyor belt; the paper towel stack a refers to stacked wet tissues, and in this embodiment, the conveyor belt 4 inputs 11 sections of paper towel stacks a arranged in rows.

[0037] In actual application, the first conveyor belt inputs the stacks a of paper towels arranged in rows to the designated position and then stops, and then the spraying mechanism 31 moves to the top of the first conveyor belt under the drive of the horizontal driving mechanism 33, and the quantitative mechanism 32 connects the liquid storage tank 2 and the spraying mechanism 31 to start quantitative spraying, and each nozzle 311 wets the corresponding stack of paper towels a respectively. During the spraying process, the horizontal driving mechanism 33 drives the spraying mechanism 31 to move slowly horizontally to uniformly humidify the entire stack of paper towels a; after humidification is completed, the first conveyor belt restarts to output the humidified stack of paper towels a to the next process, and at the same time, the second conveyor belt inputs the stacks a of paper towels arranged in rows to the designated position and then stops, and repeats the above spraying process to achieve batch production.

[0038] In this embodiment, a spray mechanism 31 slidably connected to the frame 1 humidifies the stacks a of paper towels on each conveyor belt 4, and controls the amount of cleaning liquid through a metering mechanism 32, thereby accurately controlling the degree of wetting of the stacks a of paper towels. In addition, the spray mechanism 31 is composed of a plurality of nozzles 311 arranged in a row and corresponding one-to-one to the stacks a of paper towels, thereby ensuring uniform wetting of each stack a of paper towels, standardizing the product, and facilitating product quality assurance.

[0039] In this embodiment, specifically, a first horizontal sliding group 11 and a second horizontal sliding group 12 are symmetrically arranged on both sides of the frame 1; the first horizontal sliding group 11 includes a first horizontal guide rail 111 and a first slider 112; the second horizontal sliding group 12 includes a second horizontal guide rail 121 and a second slider 122; the two ends of the spray mechanism 31 are respectively arranged on the first slider 112 and the second slider 122.

[0040] With the above design, the spray mechanism 31 is simply connected to the frame 1 by sliding, and the symmetrical design can make the spray mechanism 31 more stable when moving horizontally.

[0041] As a preferred embodiment of the present invention, the horizontal drive mechanism 33 includes a power module 331 and a transmission module 332; the transmission module 332 includes a first synchronous belt group and a second synchronous belt group symmetrically arranged on both sides of the frame 1;

[0042] The first synchronous belt set includes a first synchronous wheel 301, a first synchronous belt and a second synchronous wheel 302; the first synchronous wheel 301 is connected to the power module 331 by transmission; the first synchronous wheel 301 and the second synchronous wheel 302 are connected by the first synchronous belt;

[0043] The second synchronous belt set includes a third synchronous wheel 303, a second synchronous belt and a fourth synchronous wheel 304; the third synchronous wheel 303 and the fourth synchronous wheel 304 are connected by the second synchronous belt transmission;

[0044] The first synchronous wheel 301 and the third synchronous wheel 303 are connected by a first rotating shaft, and the second synchronous wheel 302 and the fourth synchronous wheel 304 are connected by a second rotating shaft.

[0045] The first slider 112 is provided with a first tooth block 1121 connected to the first synchronous belt; the second slider 122 is provided with a second tooth block 1221 connected to the second synchronous belt.

[0046] As a further preference of this embodiment, the power module 331 includes a motor 3311, a third synchronous belt, a driving wheel 305 and a driven wheel 306; the driving wheel 305 and the driven wheel 306 are connected by a third synchronous belt; the driven wheel 306 is connected to the first synchronous wheel 301.

[0047] Under the above-mentioned preferred embodiment, the motor 3311 first drives the driving wheel 305 to rotate, and then drives the driven wheel 306 to rotate through the transmission of the third synchronous belt. The driven wheel 306 drives the first synchronous wheel 301 to rotate through the transmission of the first rotating shaft. The first synchronous wheel 301 drives the second synchronous wheel 302 to rotate through the first synchronous belt. At the same time, under the transmission of the first rotating shaft and the second rotating shaft, the third synchronous belt and the fourth synchronous belt rotate synchronously, thereby driving the sliding of the first gear block 1121 and the second gear block 1221. The forward and reverse rotation of the motor 3311 can synchronously move the first slider 112 and the second slider 122 forward or backward horizontally.

[0052] It should be noted that, since the cleaning liquid is recycled, it is inevitable that the cleaning liquid contains a small amount of paper scraps. Therefore, the above-mentioned design of the liquid storage tank 2 can avoid the problem of paper scraps clogging the pipeline and causing inaccurate spraying amount.

[0053] In addition, in order to facilitate the staff to disassemble and clean the interior of the liquid storage tank 2, the upper end surface of the liquid storage tank 2 is closed by a detachable end cover 26.
