[0024] Example: Figures 1-8 As shown in this embodiment, a plastic cup sealing film feeding mechanism is provided, including a support frame B1 and a plurality of sealing film storage bins B2 disposed on the support frame. The sealing film storage bins are connected to the support frame via sealing film dispensing ports B201. A flipping film dispensing mechanism B3 is disposed at the lower part of the support frame. The flipping film dispensing mechanism includes a retractable film dispensing plate B301 and a plurality of film dispensing suction cups B302 disposed on the film dispensing plate. The film dispensing suction cups correspond one-to-one with the sealing film dispensing ports. The film dispensing plate and film dispensing suction cups are driven by a flipping drive assembly to achieve 180-degree flipping operation.

[0025] In this embodiment of the invention, the shape of the sealing film dispensing port matches the sealing film, and the diameter of the sealing film dispensing port is larger than that of the film dispensing suction cup. This facilitates the film dispensing suction cup to contact and adhere to the sealing film located at the bottom layer through the sealing film dispensing port, thereby removing the sealing film. In addition, the size of the sealing film dispensing port is slightly smaller than the size of the sealing film. In the initial state, the sealing film can be confined within the sealing film storage compartment and will not come out without force. After the film dispensing suction cup adheres to the sealing film, it can be removed due to a certain external force.

[0026] In this embodiment of the invention, the film suction cup is connected to the external negative pressure adsorption device via an air path, and the negative pressure adsorption device can be an air pump.

[0027] During operation: The sealing film is placed in the sealing film storage compartment. When the plastic cup holder moves to the bottom of the flipping film-retrieving mechanism, the telescopic cylinder drives the film-retrieving plate to move upward, so that each film-retrieving suction cup contacts the sealing film at the bottom of the sealing film storage compartment and adsorbs the sealing film. The telescopic cylinder retracts, and the film-retrieving suction cups take out the sealing film at the bottom layer through the sealing film feeding port. The flipping cylinder drives the flipping shaft to rotate, causing the film-retrieving suction cups to flip 180 degrees downward along the flipping shaft, so that the sealing film on each film-retrieving suction cup is aligned with the sealing film placement slot. Then, the telescopic cylinder drives the film-retrieving suction cups to approach the sealing film placement slot, the film-retrieving suction cups release, and each sealing film falls into the sealing film placement slot of the plastic cup holder.

[0028] In this embodiment of the invention, the film-taking plate is driven to extend and retract by the film-taking telescopic cylinder B303.

[0029] In this embodiment of the utility model, the flipping drive assembly includes a flipping shaft B304, both ends of which are rotatably engaged with the support frame. For example, the flipping shaft and the support frame can be connected by bearings. The flipping shaft is fixed to the middle of the telescopic cylinder. A flipping cylinder B305 is provided on the side of the support frame to drive the flipping shaft, the telescopic cylinder, the film-taking plate, and the film-taking suction cup to rotate synchronously.

[0030] In this embodiment of the utility model, the sealing film feeding bin B2 includes four large sealing film limiting rods B202, and the sealing film B4 includes a circular film body B401 and an arc-shaped tear film B402. The four large sealing film limiting rods form a film body limiting space for placing the circular film body. Two small sealing film limiting rods B203 are also provided between the two sealing film limiting rods located at the rear. The two small sealing film limiting rods form a receiving space for accommodating the arc-shaped tear film of the sealing film.

[0031] In this embodiment of the utility model, in order to limit the sealing film, a pressure block B204 is provided in the film limiting space, and a pull handle B205 is provided above the pressure block.

[0032] In this embodiment of the utility model, a plastic cup feeding mechanism B5 is provided below the flipping film taking mechanism. The plastic cup feeding mechanism includes a worktable B501 and a turntable B502 disposed on the worktable. A rotating shaft B503 is provided between the center of the turntable and the worktable. The rotating shaft is driven to rotate by a motor disposed in the worktable. A plurality of plastic cup placement seats B504 for placing plastic cups are provided on the surface of the turntable. A plurality of plastic cup placement slots B505 for placing plastic cups are provided on the plastic cup placement seats.

[0033] In this embodiment of the utility model, the multiple plastic cup placement slots on the plastic cup placement seat correspond one-to-one with the multiple film-removing suction cups after being flipped 180 degrees.

[0034] In this embodiment of the utility model, a support rod B6 is provided at the rear of the support frame, the lower end of the support rod is fixed to the workbench, a support block B7 is installed on the support rod, and an auxiliary pushing mechanism B8 is installed below the support block to gently push the sealing film that has not been placed in the plastic cup placement slot into the sealing film placement slot.

[0035] In this embodiment of the utility model, the auxiliary pushing mechanism B8 includes an auxiliary pushing plate B801 and an auxiliary pushing plate cylinder B802 for pushing the auxiliary pushing plate to move along the width direction of the plastic cup placement seat. The auxiliary pushing plate cylinder is mounted on a support block.

The flat plates are correspondingly disposed on the upper surface of the plastic cup placement seat and can move along the upper surface of the plastic cup placement seat.

[0036] When the flipping film-retrieving mechanism delays material feeding due to delays or other reasons, some sealing films are not aligned with the sealing film placement slot and are instead on the upper surface of the plastic cup placement seat. By driving the auxiliary push plate cylinder to gently push the auxiliary push plate forward, the sealing films that are not in the sealing film placement slot can be pushed into the sealing film placement slot.

[0037] In this embodiment of the present invention, a sealing film placement groove 507 is provided above the plastic cup placement groove, and the sealing film placement groove is slightly larger than the plastic cup placement groove; the sealing film can be an aluminum foil sheet.
