[0016] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0017] As shown in the figure, a paper tube conveying device includes a storage rack 1, and the storage rack 1 includes a column 12 and a column 13. A crossbeam 14 is arranged between the column 12 and the column 13. There are two columns 12 and two columns 13 respectively, which play the role of supporting the two crossbeams 14. A guardrail 15 is arranged between the two crossbeams 14. The guardrail 15 prevents the paper tube 6 from falling. The height of the crossbeam 14 close to the lifting mechanism 2 is lower than the height of the opposite side. After the paper tube 6 is placed on the storage rack 1, since the crossbeam 14 presents a slope toward the lifting mechanism 2, the paper tube 6 will slide to the discharge end of the storage rack 1 due to the action of gravity.

[0018] The discharge end of the storage rack 1 is connected to the bottom end of the lifting mechanism 2, and the top end of the lifting mechanism 2 is connected to the conveyor belt 3 through a transition bracket 5, and the cross-section of the transition bracket 5 is flat and L-shaped. A plurality of limit sensing probes 31 are arranged on the conveyor belt 3. The lifting mechanism 2 includes a sprocket 21 and a chain 22, and the sprocket 21 is connected to a servo motor 23, and the paper tube supporting claw 4 is connected to the chain 22. The servo motor 23 drives the sprocket 21 to rotate, thereby driving the chain 22 to make an up and down circular motion. Since the storage rack 1 is inclined, the height of the discharge end of the storage rack 1 is lower than the height of the opposite end, and the discharge end of the storage rack 1 is provided with an avoidance area 11, and the avoidance area 11 is to facilitate the passage of the paper tube supporting claw 4 and lift the paper tube 6. The number of the paper tube supporting claw 4 can be determined according to the required number of paper tubes and is not limited here. The paper tube supporting claw 4 includes a connecting portion 41 and a limiting portion 42. The limiting portion 42 is vertically fixed to the chain 22 by bolts. The limiting portion 42 includes an arc groove 421 and an edge protrusion 422. The arc groove 421 is located between the edge protrusion 422 and the connecting portion 41; between the top of the lifting mechanism 2 and the conveyor belt 3. The highest point of the edge protrusion 422 close to the arc groove 421 is co-centered with the arc groove 421. The radius of the arc groove 421 is not less than the radius of the paper tube, so that the paper tube 6 can be stably raised in the paper tube supporting claw 4 along with the chain 22 during transportation.

[0019] When in use, first place multiple paper tubes 6 on the storage rack 1. The paper tubes 6 will gradually approach the bottom end of the lifting mechanism 2 due to gravity. The paper tubes 6 at the avoidance area 11 are waiting to be lifted. After the servo motor 23 is started, the paper tube supporting claws 4 make a circular motion with the chain 22. When the paper tube supporting claws 4 pass through the avoidance area 11, they will contact the bottom end of the paper tube 6, and then lift the paper tube 6; when the paper tube supporting claws 4 continue to move upward and reach the highest point of the lifting mechanism 2, since the highest point of the transition bracket 5 is connected to the highest point of the lifting mechanism 2, the height of the conveyor belt 3 is lower than the height of the top of the lifting mechanism 2, and the paper tube supporting claws 4 continue to move to push the paper tube 6 onto the transition bracket 5, and the paper tube 6 slides along the transition bracket 5 onto the conveyor belt 3. The paper tube 6 is transported to a specific workstation at a high place along the conveyor belt 3, and the limit sensing probe 31 is responsible for detecting whether the movement of the paper tube 6 on the conveyor belt is in place as expected.

[0020] The above embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
