Preferably, the lifting driving assembly 210 is a motor-screw sliding pair, which has the advantage of being able to accurately control the lifting range of the second horizontal conveying belt 32. Of course, those skilled in the art can also use other conventional lifting mechanisms to achieve the same purpose.

[0050] In the present embodiment, the rack 1 is further provided with a position sensor 101; the position sensor 101 is used for detecting whether there are paper towels a at the end of the horizontal conveying channel b. The position sensor 101 is connected to an external controller to coordinate the movement of each unit.

[0051] In actual application, the anti-falling unit 4 arranged on the turnover unit 2 is further included; the anti-falling unit 4 is used for closing or opening both sides of the horizontal conveying channel b.

[0052] As a preferred embodiment of the present application, the anti-falling unit 4 comprises a first blocking module 41 and a second blocking module 42 arranged symmetrically; the first blocking module 41 and the second blocking module 42 can independently operate and are respectively used for closing or opening one side of the horizontal conveying channel b.

[0053] As a further preferred embodiment of the present embodiment, the first blocking module 41 and the second blocking module 42 are mirror structures (the specific components of the second blocking module 42 are omitted); the first blocking module 41 comprises a first sliding structure 411 arranged on the first rotating module 21, a second sliding structure 412 arranged on the second rotating module 22, and a support plate 413 slidably connected to the first sliding structure 411 and the second sliding structure 412 at both ends; the first sliding structure 411 and the second sliding structure 412 are mirror structures; the first sliding structure 411 comprises a second sliding rail 4111 and a sliding driving assembly 4112 for driving the support plate 413 to slide along the second sliding rail 4111.

[0054] The anti-falling unit 4 under the above design independently closes or opens one side of the horizontal conveying channel b by arranging the first blocking module 41 and the second blocking module 42, so that the application scenarios of the device are more diversified. It should be noted that in the present embodiment, the support plate 413 is divided into two parts, and the sliding driving assembly 4112 has two power sources. The two support plates 413 are fixed on the two power sources, respectively. Compared with using a whole support plate 413, the split support plate 413 reduces the sliding distance, which not only responds more quickly, but also reduces the space occupancy.

[0055] In actual application, the application principle of the present embodiment is as follows: the continuous paper towels a enter the horizontal conveying channel b from the shaft center of the first rotating disc 211, and then are transported along the horizontal conveying channel b under the driving of the first horizontal conveying belt 31 and the second horizontal conveying belt 32 until the position sensor 101 detects the paper towel a at the front end. The first horizontal conveying belt 31 and the second horizontal conveying belt 32 stop working, the rotating driving assembly of the turnover unit 2 works to drive the first rotating disc 211 and the second rotating disc 221 to synchronously rotate 90° clockwise. At this time, the first blocking module 41 works to close one side of the horizontal conveying channel b to prevent the paper towel a from falling due to gravity. Similarly, the first rotating disc 211 and the second rotating disc 221 can also be rotated 90° counterclockwise. Finally, according to different production requirements, the nodes for controlling the first horizontal conveying belt 31 and the second horizontal conveying belt 32 to work again are selected, so as to realize the output of the paper towel a turned over by 90°, 180°, etc.
