The positioning rod 9 extends along the conveying direction of the paper tube 22, and the positioning rod 9 is used to position the paper tube 22 during the conveying process. The positioning rod 9 is installed on the L-shaped support plate 5 through the connecting rod 8, and the L-shaped support plate 5 is slidably connected to the legs 6 of the conveying frame 3, so as to facilitate the adjustment of the distance between the two positioning rods 9. After adjusting to the appropriate position, the fastening bolts 7 are screwed to fix the L-shaped support plate 5.

[0021] The workbench 1 is also provided with a curling device 10 for curling the paper tube 22 , and the workbench 1 is provided with a driving mechanism for driving the curling device 10 to move up and down, and for driving the rotating part to rotate.

[0022] The rotating member includes an upper turntable 11 and a lower turntable 12, and the upper turntable 11 and the lower turntable 12 are connected by a plurality of fixing bolts 13 distributed circumferentially with the center of the rotating member as the center. A plurality of supporting nuts 14 are provided between the upper turntable 11 and the lower turntable 12, and the supporting nuts 14 are installed on the fixing bolts 13. The connection between the upper turntable 11 and the lower turntable 12 is achieved by tightening the bolts 7, so that the upper turntable 11 and the lower turntable 12 can move synchronously.

[0023] A plurality of first clamping claws 15 are provided between the upper turntable 11 and the lower turntable 12, and the first clamping claws 15 are connected to the output end of the first electric telescopic rod 16, and the first electric telescopic rod 16 is installed on the upper end surface of the lower turntable 12, and the first clamping claws 15 correspond to the positions of the positioning grooves 2. A supporting nut 14 is provided between the upper turntable 11 and the lower turntable 12, so that there is installation space for the first clamping claws 15 and the first electric telescopic rod 16 between the upper turntable 11 and the lower turntable 12.

[0024] The rotating member is connected to the driving mechanism through a rotating shaft. The rotating shaft is a hollow structure. A support rod is provided on the inner circumference of the rotating shaft. The bottom of the support rod is connected to the inner wall of the workbench 1. A mounting plate 17 is provided on the top of the support rod. A third electric telescopic rod 18 is provided on the mounting plate 17. The output end of the third electric telescopic rod 18 is connected to a sponge suction cup 23. The driving mechanism includes a motor. The motor is connected to the rotating shaft through a gear assembly to drive the rotating member to rotate. The mounting plate 17 is fixedly installed through the support rod. A third electric telescopic rod 18 is provided on the mounting plate 17. The output end of the third electric telescopic rod 18 is connected to the sponge suction cup 23. The utility model can be used for rotating parts within a certain diameter range. The paper tube 22 is subjected to curling processing. When the diameter of the paper tube 22 is small, in order to prevent the conveyor belt 4 from being unable to deliver the paper tube 22 into the positioning groove 2 during the conveying of the paper tube 22, so that the rotating part cannot deliver the paper tube 22 from the loading position to the processing position, or two paper tubes 22 are delivered into the conveying groove, resulting in the failure of the paper tube 22 to curl, when the conveyor belt 4 delivers the paper tube 22 to the specified position, the conveyor belt 4 stops working, and by starting the third electric telescopic rod 18, the sponge suction cup 23 is driven to absorb the paper tube 22 at the front end and pull it into the positioning groove 2, and then the paper tube 22 is transported to the processing station by rotation, and the conveyor belt 4 is started to convey the next paper tube 22 forward.

[0025] An arc-shaped guide frame 19 is provided on the top of the workbench 1, and the center of the guide frame 19 coincides with the center of the rotating member. In the process of the rotating member carrying the paper tube 22 for selection, the guide frame 19 can ensure that the paper tube 22 is always located in the positioning groove 2. When the paper tube 22 rotates to the unloading position, that is, the guide frame 19 no longer limits the position of the paper tube 22, the first electric telescopic rod 16 at the unloading position is started, driving the first clamping claw 15 to push the paper tube out, and the paper tube 22 falls into the packaging box on one side of the workbench 1, thereby completing the unloading.

[0026] A second clamping claw 20 is provided on the workbench 1 at the processing position of the paper tube 22, and the second clamping claw 20 is connected to the output end of the second telescopic rod 21. The second clamping claw 20 cooperates with the first clamping claw 15 to position and clamp the paper tube 22. The first clamping claw 15 and the second clamping claw 20 are both V-shaped structures. When the paper tube 22 is located at the processing position, the corresponding second electric telescopic rod on the positioning groove 2 where the paper tube 22 is located is started, so that the first clamping claw 15 and the second clamping claw 20 clamp the paper tube 22, so that the central axis of the paper tube 22 coincides with the central axis of the pressure head on the curling device 10. When curling paper tubes 22 of different diameters, the staff needs to replace pressure heads of different diameters.

[0027] It is worth noting that the utility model can perform curling processing on paper tubes 22 within a certain diameter range. The diameter of the paper tube 22 is greater than the minimum distance between the rotating member and the guide frame 19, ensuring that the paper tube 22 will not move out of the positioning groove 2 during the movement of the rotating member.
