[0029] Referring to Figure 1 , an automatic centering rewinding device includes a plurality of rewinding devices 1 and a conveying device 2. The conveying device 2 includes a conveyor belt 21, and the plurality of rewinding devices 1 are arranged along the length direction of the conveyor belt 21. When the rewinding device operates, the rewinding device 1 winds using a paper tube, and then the rewinding device 1 transfers the paper tube with the material to the conveyor belt 21, and the paper tube is transported by the conveyor belt 21 to a designated position for sorting.

[0030] Specifically, the rewinding device 1 includes a rewinding mechanism 11, a centering loading mechanism 12 and a discharging mechanism 13 arranged on one side of the conveying device 2. The rewinding mechanism 11 is a rewinder. After the paper tube is fed into the rewinding mechanism 11, the rewinding mechanism 11 winds the paper tube. The specific structure and specific working principle of the rewinding mechanism 11 are prior art, and the rewinding mechanism 11 can be obtained by purchase and will not be elaborated here.

[0031] Referring to Figure 1 , Figure 2 and Figure 3, the upper feeding mechanism 12 in the middle and upper part includes a storage bin 121, a feeding structure 122 arranged in the storage bin 121, and a connecting structure 123. In this embodiment, the storage bin 121 and the rewinding mechanism 11 are respectively located on both sides of the conveyor belt 21. The storage bin 121 has a storage cavity and a discharge port. The storage cavity can hold paper tubes for storage, which is convenient for being transported by the feeding structure 122. The feeding structure 122 includes a number of feeding transport plates 1221 and a driving component for driving the feeding transport plates 1221. The feeding transport plates 1221 are arranged in an "L" shape to support and transport the paper tubes. A number of feeding transport plates 1221 are arranged in an oval shape. Driven by the driving component, a number of feeding transport plates 1221 will continuously transport the paper tubes to the discharge port along an oval moving path to enter the connecting structure 123. In this embodiment, the driving component is a chain drive. It can be understood that the driving component can also be other forms such as a gear drive or a belt drive.

[0032] The connecting structure 123 includes a connecting support base 1231 arranged on the storage bin 121 and a connecting guide rail 1232 arranged on the connecting support base 1231. One end of the connecting guide rail 1232 is the feeding place, and the feeding place extends and is connected to the inside of the discharge port of the storage bin 121. The other end of the connecting guide rail 1232 is the discharging place, and the discharging place is located above the middle of the rewinding mechanism 11. The connecting guide rail 1232 has a first limiting part 12321 and a second limiting part 12322 arranged in a surrounding manner. The first limiting part 12321 and the second limiting part 12322 limit the paper tube in a surrounding form. The sizes of the first limiting part 12321 and the second limiting part 12322 are adapted to the size of the paper tube, and the distance between the first limiting part 12321 and the second limiting part 12322 is adapted to the length of the paper tube.

[0033] Refer to Figure 4 and Figure 5 , the connecting support base 1231 includes an extension support block 12311 fixedly connected to the storage bin 121 and a connecting seat 12312 arranged on the extension support block 12311. The connecting seat 12312 is fixedly connected to the connecting guide rail 1232. At the same time, in order to facilitate adjusting the position of the connecting support base 1231, a number of fitting holes are provided on the extension support block 12311, and fitting adjustment slots are provided on the connecting seat 12312 that cooperate with the fitting holes; the connecting seat 12312 is detachably connected to the extension support block 12311 through the fitting adjustment slots. By providing the fitting holes and the fitting adjustment slots, the position of the connecting seat 12312 can be adjusted by adjusting the position of the fitting adjustment seat relative to the fitting holes, thereby adjusting the position of the connecting guide rail 1232, and then adjusting the discharging position of the connecting guide rail 1232 relative to the rewinding mechanism 11.

[0034] In order to ensure that the paper tube can enter the rewinding mechanism 11 efficiently and effectively, a flipping limit member 12323 is provided at the connection between the connecting guide rail 1232 and the rewinding mechanism 11, that is, at the discharging position. At the same time, the upper and middle feeding mechanism 12 further includes a detection structure 124, and the detection structure 124 includes a number of photoelectric sensors arranged on the connecting guide rail 1232. The flipping limit member 12323 is hinged at the discharging position. The flipping limit member 12323 is a rotatable baffle, and the flipping limit member 12323 can be specifically driven by a motor or a cylinder. In the limit state, the flipping limit member 12323 flips upward to limit the paper tube. In the state of releasing the limit, the flipping limit member 12323 flips downward to release the limit on the paper tube. A number of through holes for adapting to the photoelectric sensors are provided on the side of the connecting guide rail 1232 away from the rewinding mechanism 11. The photoelectric sensors are fixed on this side of the connecting guide rail 1232 and their detection ends face the inside of the connecting guide rail 1232 through the through holes. When there is a paper tube in the connecting guide rail 1232, the photoelectric sensors can detect the in-place situation, so as to cooperate with the flipping limit member 12323 to limit or release the limit on the paper tube.

[0035] Refer to Figure 6 , the discharging mechanism 13 is connected to the rewinding mechanism 11 and the conveying device 2. When the rewinding mechanism 11 finishes rewinding, the paper tube with the material is placed on the discharging mechanism 13, and the discharging mechanism 13 transfers the paper tube to the conveyor belt 21. Specifically, the discharging mechanism 13 includes a discharging structure 131 and a discharging lifting structure 132 provided on the rewinding mechanism 11. The discharging structure 131 includes a discharging connecting plate 1311 rotatably connected to the rewinding mechanism 11 and a discharging driving member for driving the discharging connecting plate 1311. The discharging driving member is a cylinder. Driven by the discharging driving member, the discharging connecting plate 1311 will swing to form a horizontal state or a state inclined towards the conveyor belt 21. When the paper tube with the material is placed on the inclined discharging connecting plate 1311, it will roll onto the conveyor belt 21.

[0036] The blanking lifting structure 132 is used to support the paper tube and place the paper tube on the blanking connection plate 1311. The blanking lifting structure 132 includes a blanking lifting block 1321 and a lifting driving member for driving the blanking lifting block 1321. The blanking lifting block 1321 penetrates through the blanking connection plate 1311 and can be lifted and lowered under the drive of the lifting driving member. In this embodiment, the blanking connection plate 1311 is provided with a relief groove for mating with the blanking lifting block 1321. The blanking lifting block 1321 penetrates through the relief groove, and the length of the relief groove is less than the length of the material. The lifting driving member is a cylinder. At the same time, the blanking lifting block 1321 has a limiting groove for mating with the paper tube. After the rewinding is completed, the rewinding mechanism 11 places the paper tube with the material in the limiting groove. Subsequently, the blanking lifting block 1321 drives the paper tube with the material to descend and place it on the blanking connection plate 1311. The blanking connection plate 1311 rotates and tilts so that the paper tube with the material rolls onto the conveyor belt 21 and moves to a designated position for sorting.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0038] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
