[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 3 , in the embodiment of the present invention, an automatic curling device for paper can production includes a workbench 1. A curling machine 2 for curling the paper can is vertically slidably connected to the outer wall of the workbench 1. A turntable 3 is rotatably installed above the workbench 1. A positioning block 4 is fixed to the top end of the turntable 3. A transmission mechanism 5 is further provided on the workbench 1 and the turntable 3; the transmission mechanism 5 includes a transmission unit and a discharging unit; the transmission unit is used to provide power for the intermittent rotation of the turntable 3; the discharging unit is used to automatically discharge the paper can after curling.

[0020] The transmission unit includes a drive motor 501, a first gear 502, and a second gear 503; the drive motor 501 is installed inside the workbench 1, and the drive motor 501 is used to drive the first gear 502 to rotate; the first gear 502 is connected to the output end of the drive motor 501 through a rotating shaft and a coupling, and the first gear 502 is used to drive the second gear 503 to rotate; the second gear 503 is fixed to the outer wall of the shaft rod of the turntable 3, and the second gear 503 is used to drive the turntable 3 to rotate synchronously.

[0021] The discharging unit includes a support ring 504, a connecting rod 505, a force-receiving block 506, and an abutting block 507; the support ring 504 is vertically slidably sleeved on the outer wall of the positioning block 4, and the support ring 504 is used to provide support for the paper can; the connecting rod 505 is fixed to the bottom end of the support ring 504 and extends into the workbench 1, and the connecting rod 505 is used to drive the support ring 504 to move synchronously; the force-receiving block 506 is fixed to the bottom end of the connecting rod 505 and is located inside the workbench 1, and the force-receiving block 506 is used to receive the thrust from the abutting block 507; the abutting block 507 is fixed inside the workbench 1, and the abutting block 507 is used to give the force-receiving block 506 an upward moving thrust.

[0022] In this embodiment: When using this device, the paper can to be curled is sleeved on the outer wall of the positioning block 4. At this time, the bottom of the paper can contacts the top of the support ring 504. When the driving motor 501 is started, the working driving motor 501 drives the first gear 502 to rotate. The rotating first gear 502 gives the second gear 503 meshed with its outer wall a rotational thrust. The second gear 503 rotates under the force. The rotating second gear 503 will synchronously drive the turntable 3 to rotate, so that the positioning block 4 fixed on the turntable 3 moves circumferentially as the turntable 3 rotates to below the curling machine 2, aligning the paper can with the position below the curling machine 2. At this time, the outer wall teeth of the first gear 502 will no longer mesh with the outer wall teeth of the second gear 503, and the turntable 3 stops rotating. Thus, the curling machine 2 curls the paper can on the positioning block 4. After curling is completed, the outer wall teeth of the first gear 502 contact the second gear 503 again to give the second gear 503 a rotational thrust. The second gear 503 driven by the force drives the turntable 3 and the positioning block 4 to rotate, moving the curled paper can on the positioning block 4 out from below the curling machine 2. At this time, the positioning block 4 inside the curled paper can moves to below the abutting block 507. The abutting block 507 contacts the outer wall of the force-receiving block 506 to give the force-receiving block 506 an upward extrusion thrust. The force-receiving block 506 driven by the force synchronously drives the connecting rod 505 and the support ring 504 to move upward, separating the curled paper can sleeved on the outer wall of the positioning block 4 and contacting the top of the support ring 504 from the positioning block 4, that is, realizing the automatic unloading of the curled paper can, reducing the driving unit and lowering the cost.

[0023] Please refer specifically to Figures 1 - 3 , one side outer wall of the abutting block 507 is in an inclined state. The position where the abutting block 507 is located coincides with the circumferential movement track of the force-receiving block 506. The outer wall of the force-receiving block 506 is integrally spherical. A chute for the vertical movement of the force-receiving block 506 is formed on the inner wall of the turntable 3. The number of force-receiving blocks 506 is set to be multiple. Multiple force-receiving blocks 506 are grouped in pairs. The force-receiving blocks 506 in the same group are respectively below a support ring 504. The outer wall teeth of the first gear 502 are distributed at 180 degrees on the outer wall of the first gear 502. The outer wall teeth of the first gear 502 mesh with the outer wall teeth of the second gear 503.

[0024] In this embodiment: With this structure, when the force-receiving block 506 moves circumferentially as the turntable 3 rotates, the force-receiving block 506 can move to contact the outer wall of the abutting block 507. The inclined surface of the abutting block 507 gives the force-receiving block 506 an upward thrust, and simultaneously pushes the support ring 504 upward, achieving the effect of automatic unloading.

[0025] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
