In an embodiment of the present invention, the rubber ring 33 is made of high-elasticity rubber, and the rubber ring 33 is fixedly bonded to the annular groove.
When the automatic paper feeding device works, in the prior art, after the wind-up roller 5 drives the paper tape to feed paper, the third motor 25 rotates to drive the cam 26 to drive the press rod 21 to slide downwards to punch the paper tape to obtain a circular cup bottom, but the cup bottom is easy to cause cup bottom dragging displacement when being separated from the paper tape after the cup bottom is punched, which is not beneficial to subsequent cup bottom transfer alignment, at the moment, the first motor 6 drives the wind-up roller 5 to rotate intermittently to further enable the paper discharge roller 4 to feed paper intermittently, and meanwhile, the third motor 25 is controlled by the controller to drive the cam 26 to rotate to further extrude the limiting plate 22, so that the limiting plate 22 drives the press rod 21 to slide downwards to punch the paper tape, at the moment, as the oil cylinder 10 is arranged in the blind hole 9, the oil cylinder 10 supports the bearing platform 14 by matching with the spring, the press rod 21 presses the bearing platform 14 when the paper tape is punched downwards, and drives the, because the oil cylinder 10 is filled with hydraulic oil, when the pressure lever 21 rebounds upwards under the action of the first spring 15 after extruding the bearing platform 14, the hydraulic oil in the oil cylinder 10 is limited by the damping hole 12, so that the upwards sliding reset time of the bearing platform 14 is delayed, at the moment, the geneva mechanism 16 is driven by the second motor 17, so that the turntable 8 is driven to rotate, the cup bottom is smoothly separated from the paper tape, the cup bottom is slowly lifted to the top of the turntable 8 along with the piston 11 after being separated from the paper tape, and then the next process operation is performed, so that the separation efficiency of the cup bottom and the paper tape is increased, the cup bottom is ensured to be in the correct position, and the production efficiency of the paper cup; after the bearing platform 14 slides downwards under the extrusion of the pressure lever 21, the bearing platform 14 is matched with the top of the oil cylinder 10 to extrude the air bag 27, so that air in the air bag 27 is exhausted, when the pressure lever 21 slides upwards and resets, the bearing platform 14 slides upwards under the driving of the first spring 15 and resets, the air bag 27 exhausts air from the first hole 28 through the second hole 29, so that the cup bottom is adsorbed on the upper surface of the bearing platform 14, the displacement of the cup bottom is further reduced, and the separation efficiency of the cup bottom and the paper tape is increased; the chamfer 30 is matched with the groove 31, so that after the press rod 21 completes the blanking of the cup bottom, the press rod 21 continues to press the cup bottom, the edge of the cup bottom forms a flanging under the extrusion of the chamfer 30, further, the subsequent flanging process of the cup bottom is saved, the production equipment and the production time are saved, and the production efficiency of the paper cup is further improved; through the cooperation of the check valve with the second hole 29 and the third hole 32, when the air bag 27 is extruded by the bearing platform 14, compressed air in the air bag 27 can only be ejected through the check valve and the third hole 32, and then paper scraps in a gap between the bearing platform 14 and the blind hole 9 are blown and cleaned, so that the friction force between the bearing platform 14 and the blind hole 9 is reduced, the normal sliding work of the bearing platform 14 is further ensured, and meanwhile, when the air bag 27 expands under the action of the first spring 15 and returns to the original state, the air bag 27 only can exhaust air from the second hole 29 and the first hole 28 through the check valve, the firmness of the first hole 28 for adsorbing the cup bottom is increased, and the production efficiency of the paper cup is further improved; after the press rod 21 finishes blanking the cup bottom, the press rod 21 continues to press down the cup bottom, and at the moment, the air bag 27 is extruded by the oil cylinder 10 and the bearing platform 14, so that compressed air generated in the air bag 27 is filled into the third hole 32 through the second hole 29, and because one end of the third hole 32, which is far away from the second hole 29, is provided with the pressure limiting valve 35, after the air pressure in the third hole 32 is increased, part of the compressed air is filled into the rubber ring 33 through the fourth hole 34, so that the rubber ring 33 expands and extrudes the flanging of the cup bottom, and the flanging is further shaped by matching with the ring groove 36, thereby reducing the deformation of the flanging when the press rod 21 is separated from extrusion, further increasing the stability of flanging forming, and increasing the forming quality of the cup bottom; when depression bar 21 glides downwards under the drive of cam 26, because spiral groove 38 has been seted up to depression bar 21 periphery, platform 20 top and spiral groove 38 corresponding position have linked firmly fixture block 39, make fixture block 39 cooperation spiral groove 38, make depression bar 21 constantly rotatory at the in-process of gliding, and then when making the recess 31 blanking of depression bar 21 bottom accomplish and extrude the bottom of a cup, recess 31 drives the turn-ups position of bottom of a cup rotatory, and then constantly form even fold and imbed in fold groove 37 during making the turn-ups shaping, further increase the turn-ups's of bottom of a cup homogeneity, reduce tearing and the local excessive overlap at bottom of a cup edge, increase the shaping quality of bottom of a cup.
