DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0023] like Figures 1 to 5 As shown, a forming device for a paper cup body of the present embodiment comprises a frame 1, a table panel 2 is arranged on the top of the frame 1, a crossbeam 3 is suspended above one end of the table panel 2, a cup mold 4 suspended above the table panel 2 is fixed to the crossbeam 3, a through hole 21 is arranged on the table panel 2 below the cup mold 4, a paper rolling mechanism 5 which can pass through the through hole 21 and roll the paperboard onto the cup mold 4 is arranged below the table panel 2, and a liftable ultrasonic sealing machine 6 is arranged above the cup mold 4.

[0024] This embodiment is described by taking the example of rolling a conical paper cup as an example, but it is not limited to this. The forming device of this embodiment can also be used for a conical bowl, or for a cylindrical body after changing the shape of the cup mold 4. During operation, the cut cardboard is sent to the table panel 2 below the cup mold 4. In order to ensure that the cardboard is not skewed during transmission, the cross beam 3 is suspended with a paper pressing rod 7 on both sides of the cup mold 4. The paper pressing rod 7 is fixed to the cross beam 3 with an adjustable height through an adjustment plate with a long hole. The table panel 2 is provided with a guide vertical plate 8 for limiting the cardboard outside the left and right sides of the through hole 21; the paper pressing rod 7 limits the cardboard to slide along the table panel 2 without curling up, and the guide vertical plate 8 limits the cardboard from both sides to form a slideway to guide the cardboard. In addition, in order to make the cardboard stop accurately at the appropriate position and not bounce off during the upward rolling process, the table panel 2 below the front end of the cup mold 4 is provided with a limit rod 10 for positioning the cardboard transmission position, and the limit rod 10 is a vertical rod.

[0025] The paper rolling mechanism 5 includes two rotating shafts 51 rotatably connected to the bottom of the table panel 2, each of the two rotating shafts 51 is fixed with a rolling plate 52 and a gear 53, the two gears 53 are meshed, one of the rotating shafts 51 is fixed with a connecting plate 54, and the frame 1 is fixed with a rolling cylinder 55, and the front end of the piston rod of the rolling cylinder 55 is hinged to the free end of the connecting plate 54.

[0026] When the cardboard is parked right above the paper rolling mechanism 5, the two ends of the cardboard are restricted by the paper pressing rod 7, and the side surfaces of the two ends touch the guide vertical plate 8, and the middle of the cardboard is located above the rolling plate 54; then the rolling cylinder 55 extends out and drives the rotating shaft 51 to rotate through the connecting plate 54. Because the gears 53 on the two rotating shafts 51 have the same number of teeth and mesh with each other, the two rotating shafts 51 rotate synchronously and in opposite directions. That is, for this embodiment, when one of the rolling plates 52 turns up, the other rolling plate 52 will also turn up synchronously, thereby synchronously pushing the cardboard upward from the bottom of the two ends of the cardboard, so that the cardboard is rolled into a tube with the cup mold 4 as the core; because the shape of the rolling plate 52 follows the side and top shapes of the cup mold 4, eventually, the cardboard will be pressed against the cup mold 4 by the rolling plate 52.

[0027] The two ends of the cardboard pressed against the cup mold 4 overlap in the middle of the top of the cup mold 4, and then the ultrasonic sealer 6 is pressed down to use ultrasonic waves to weld the two overlapping ends of the cardboard together. The ultrasonic sealer 6 includes a lifting cylinder 61 fixed on both sides of the frame 1 and a mounting plate 62 suspended above the table panel 2. The two ends of the mounting plate 62 are fixed to the piston rods of the two lifting cylinders 61. The mounting plate 62 is fixed with a transducer 63 for ultrasonic welding and sealing. A vibrator 65 is connected to the bottom of the transducer 63 through a horn 64. The vibrator 65 is located directly above the cup mold 4. In order to enable the vibrator 65 to fully press the overlapping part of the cardboard against the cup mold 4 after it descends, the bottom of the vibrator 65 is a horizontal plane, the cross-section of the cup mold 4 is nearly waist-shaped, and the upper surface of the cup mold 4 is also flat and horizontal.

[0028] In order to achieve better ultrasonic welding effect of paper cups, the frame 1 is also provided with a liquid spraying device 9 for spraying working liquid to the welding position of paper cups. The liquid spraying device 9 includes a container for holding working liquid and a nozzle for spraying working liquid to the welding position of paperboards.

[0029] The ultrasonic sealing machine 6 generates a large amount of heat when working. In order to prevent the cardboard from being burned due to excessive temperature, a cooling fan is arranged next to the ultrasonic sealing machine 6.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
