[0026] For example 2, please refer to Figure 1-11On the basis of the first embodiment, the present invention provides a technical solution: it also includes a driving assembly 5, and the driving assembly 5 is composed of a connecting frame 501, a rotating cylinder 502, a driving motor 2 503, an adjusting threaded column 504, a moving disk 505, a rotating frame 506, a rotating sheet 507, an adjusting frame 508, a connecting arm plate 509 and a driven frame 510.

[0027] The connecting frame 501 is fixedly connected to the left side of the fixed support frame 301, the rotating cylinder 502 is fixedly connected to the middle part of the connecting frame 501 away from the fixed support frame 301, the driving motor 2 503 is fixedly connected to the middle part of the right side of the connecting frame 501, the driving motor 2 503 has an output shaft, the adjusting threaded column 504 is fixedly connected to the output shaft of the driving motor 2 503, the movable disk 505 is threadedly connected to the outside of the adjusting threaded column 504, the rotating frame 506 is fixedly connected to the outside of the rotating cylinder 502 and is located on the side away from the fixed support frame 301, the rotating piece 507 is rotatably connected to the middle part of the rotating frame 506, the adjusting frame 508 is fixedly connected to the side of the rotating piece 507 close to the rotating cylinder 502, the connecting arm plate 509 is rotatably connected to the middle part of the adjusting frame 508, the driven frame 510 is fixedly connected to the outside of the movable disk 505, and the rotating piece 507 can rotate inside the rotating frame 506.

[0028] It also includes an injection assembly 6, which consists of a fixed disc 601, an air bag 602, a connecting pipe 603, an injection ring pipe 604, an injection head 605, a telescopic sleeve 606, an auxiliary frame 607 and a connecting telescopic arc rod 608.

[0029] The fixed disc 601 is rotatably connected to the adjusting threaded column 504 away from one end of the output shaft of the driving motor 2 503, the airbag 602 is fixedly connected to one side of the fixed disc 601 and is located on the outside of the adjusting threaded column 504, the connecting tube 603 is fixedly connected to the side of the airbag 602 away from the fixed disc 601, the jet ring tube 604 is fixedly connected to the outside of the rotating cylinder 502, and the jet head 605 is fixedly connected to the outside of the jet ring tube 604. After the airbag 602 is squeezed, the internal air can be sent into the jet ring tube 604 through the connecting tube 603.

[0030] The output shaft of the second driving motor 503 passes through the connecting frame 501 and the rotating cylinder 502 and extends into the rotating cylinder 502 to be fixedly connected with the adjusting threaded column 504, and can drive the adjusting threaded column 504 to rotate when the second driving motor 503 is working. The middle part of the driven frame 510 is rotatably connected with the connecting arm plate 509 away from the side of the adjusting frame 508, and a limiting slide groove is provided on the outer side of the rotating cylinder 502 to accommodate the sliding of the driven frame 510, and the driven frame 510 can slide in the limiting slide groove.

[0031] The outer side of the fixed disc 601 is fixedly connected to the inner wall of the rotating cylinder 502. The end of the connecting tube 603 away from the airbag 602 passes through the movable disc 505 and extends to the outer side of the jet ring tube 604 to communicate with the inside of the jet ring tube 604. The connecting tube 603 is a retractable hose that can be stretched or squeezed when the movable disc 505 moves.

[0032] When the cut paper blank needs to be formed and loaded, the paper blank is placed on the inner side of the limiting fixing frame 302 through the limiting fixing frame 302, and then the electric suction cup 404 is controlled to adsorb the bottom of the paper blank, and then the driving motor 401 is controlled to work, so that the driving motor 401 drives the feeding screw 402 to rotate, so that the feeding screw 402 drives the ball nut pair moving seat 403 to move when rotating, and drives the electric suction cup 404 to move when the ball nut pair moving seat 403 moves, so that the electric suction cup 404 moves the paper blank to the lower side of the rotating cylinder 502, and releases the adsorption of the electric suction cup 404 on the paper blank, and then the folding arm 406 is controlled to fold the paper blank upward to complete the paper blank forming work, and by controlling the driving motor 401 to reverse, the ball nut pair moving seat 403 can be repeatedly controlled to move left and right on the feeding screw 402 repeatedly, so that the paper blank can be continuously loaded.

[0033] When the caliber of the paper cup needs to be adjusted, the second driving motor 503 is controlled to work, so that the second driving motor 503 drives the adjusting threaded column 504 to rotate during operation, and the moving disk 505 moves outside the adjusting threaded column 504 when the adjusting threaded column 504 rotates. When the moving disk 505 moves close to the side of the rotating frame 506, the driven frame 510 on the moving disk 505 squeezes the connecting arm plate 509, and makes the connecting arm plate 509 squeeze the adjusting frame 508. When the adjusting frame 508 is subjected to force, the rotating piece 507 rotates inside the rotating frame 506, and the rotating piece 507 rotates toward the side away from the rotating cylinder 502, so that the diameter of the formed paper cup can be adjusted, so that the diameter of the paper cup can be adjusted when the device is in use.

[0034] After the folding arm 406 folds the paper blank, the electric telescopic rod 304 is controlled to work, so that the hot pressing block 305 can perform hot pressing work on the folded paper cup.

[0035] After the paper cup is formed, the second driving motor 503 is controlled to reverse, so that the second driving motor 503 can control the adjusting threaded column 504 to rotate in the opposite direction. At this time, the driven frame 510 on the movable plate 505 pulls the connecting arm plate 509, so that the connecting arm plate 509 pulls the adjusting frame 508, and simultaneously pulls the rotating piece 507, so that the rotating piece 507 rotates inside the rotating frame 506, and the rotating piece 507 is rotated close to the outside of the rotating cylinder 502, which can reduce the diameter of the rotating piece 507 when supporting the formed paper cup. Under the action of gravity, the formed paper cup falls from the outside of the rotating piece 507 and falls to the upper side of the receiving rack 2, so that the device can automatically unload the paper cup after forming the paper cup.

[0036] When the movable disk 505 moves outside the adjusting threaded column 504, the movable disk 505 squeezes the airbag 602. After the airbag 602 is squeezed, the internal air moves to the jet ring tube 604 through the connecting tube 603, and is finally ejected through the jet head 605. The rotating sheet 507 can support the inner wall of the paper cup while the jet head 605 blows air to the inner wall of the paper cup, thereby preventing dust from adhering to the inner wall when the paper cup is formed.

[0037] When the rotating piece 507 rotates toward the side away from the rotating cylinder 502, the telescopic sleeve 606 is stretched. At the same time, the auxiliary frame 607 is displaced when the telescopic sleeve 606 is stretched, so that the auxiliary frame 607 can push the connecting telescopic arc rod 608 to move, so that the connecting telescopic arc rod 608 continues to abut against the inner wall of the formed paper cup, which is more stable when supporting the paper cup.

[0038] The second drive motor 503 is controlled to drive the adjusting threaded column 504 to reverse, so that the rotating piece 507 contracts, and the movable plate 505 moves outside the adjusting threaded column 504. At this time, the movable plate 505 is separated from the airbag 602, so that the elasticity of the airbag 602 is restored, and the jet head 605 sucks in the outside air, and the air is re-sucked into the airbag 602 through the jet head 605, the jet ring tube 604 and the connecting tube 603. When the air is sucked in, the air flow speed on the inner wall of the paper cup can be accelerated, and the inner wall of the paper cup after heat pressing can be cooled, so that the paper cup molding efficiency is higher.
