[0003] Industrial paper tubes are produced through tube rolling machines. The working principle of the tube rolling machine is to synchronously convey multiple layers of base paper through a feeding device, coat them with glue through a gluing device, and then roll them into a round tube through a tube rolling device, so that the multiple layers of base paper are firmly bonded to each other.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-3 This application is described in further detail.
[0033] The embodiment of the present application discloses a paper tube feeding device.
[0034] Embodiment 1:
[0035] Reference Figure 1 and Figure 2 The paper tube unloading device includes an unloading frame 1 and a plurality of first driving members 2, wherein the unloading frame 1 includes a frame body 11, a limiting plate 12 and a rotating plate 13, wherein the limiting plate 12 and the rotating plate 13 are both rectangular plates and are arranged along the length direction of the frame body 11. One side of the long side of the limiting plate 12 is obliquely fixedly connected to one side of the frame body 11, and one side of the long side of the rotating plate 13 is rotatably connected to the other side of the frame body 11, and a "V"-shaped placement space 14 is formed between the limiting plate 12 and the rotating plate 13 for placing the processed paper tube.
[0036] A plurality of first driving members 2 are arranged at intervals along the length direction of the frame 11. In this embodiment, the number of the first driving members 2 is three, and the first driving members 2 are cylinders. The power output shaft of the first driving member 2 is rotatably connected to the lower side of the rotating plate 13, and the cylinder body of the first driving member 2 is rotatably connected to the frame 11 to drive the rotating plate 13 to rotate. Of course, in other embodiments, the first driving member 2 may also be an oil cylinder, an electric push cylinder, etc., which is not limited in this application.
[0037] In actual application, the paper tube formed by the coil is cut by the cutting device and then transported to the placement space 14 formed between the limit plate 12 and the rotating plate 13. Then, the multiple first driving members 2 work, so that the power output shaft of the first driving member 2 is contracted to drive the rotating plate 13 to rotate downward, so that the rotating plate 13 rotates on one side higher than the other side. At this time, the paper tube falls from the rotating plate 13 under the action of gravity to achieve the unloading of the paper tube. Afterwards, the power output shaft of the first driving member 2 is extended to drive the rotating plate 13 to rotate upward so that the next processed paper tube can be placed in the placement space 14. This can effectively prevent the two paper tubes from being squeezed and damaged by each other during the unloading process, thereby minimizing the damage of the paper tube during the unloading process.
[0038] In some embodiments, the unloading rack 1 further includes a plurality of first rotating rollers 15 and a plurality of second rotating rollers 16, wherein the plurality of first rotating rollers 15 are evenly spaced along the length direction of the limiting plate 12, and the first rotating rollers 15 are rotatably connected to the limiting plate 12, and the rotating shafts of the first rotating rollers 15 are arranged along the width direction of the limiting plate 12, and the first rotating rollers 15 partially protrude from the limiting plate 12.

In the process of conveying the paper tube to the placement space 14, the paper tube contacts the plurality of first rotating rollers 15 and the plurality of second rotating rollers 16, and the friction between the paper tube and the limiting plate 12 and the rotating plate 13 during the movement is avoided as much as possible to reduce the wear of the paper tube, and the movement of the paper tube is more stable and smooth through the rotating plurality of first rotating rollers 15 and the plurality of second rotating rollers 16.

The second driving member 4 drives the frame 11 to slide, so as to drive the limit plate 12 and the rotating plate 13 to move, so that the paper tube can be stably placed in the placement space 14, that is, for a shorter paper tube, it can be located in the middle of the placement space 14, and for a longer paper tube, the center position can be located in the placement space 14, so as to be suitable for paper tubes of different sizes, thereby improving the applicability of the paper tube unloading device. It should be noted that the second driving member 4 can be a motor screw structure, or a cylinder, an oil cylinder, an electric push cylinder, etc., as long as it can drive the frame 11 to slide, and this application is not limited.
[0040] Among them, the paper tube feeding device also includes a slide rail 5 and a slider 6. The slide rail 5 is fixedly connected to the upper side of the frame 3.

Afterwards, the power output shaft of the first driving member 2 is extended to drive the rotating plate 13 to rotate upward so that the next processed paper tube can be placed in the placement space 14, so that the two paper tubes can be effectively prevented from being squeezed and damaged by each other during the unloading process, thereby minimizing the damage of the paper tube during the unloading process.
[0044] Embodiment 2:

When the paper tube falls from the rotating plate 13 to the platform 71, the paper tube first falls to the abutment plate 73 and compresses the spring 74, so as to avoid the paper tube directly falling to the platform 71 and causing damage, thereby avoiding the paper tube from being damaged during the unloading process.
