[0002] In the cosmetics industry, after liquid is filled into plastic cups, they are typically sealed with sealing film to preserve the liquid inside. Currently, the process usually involves manually filling the plastic cups, placing the sealing film at the opening, then using heat-sealing equipment to heat-seal the cups. After sealing with the film, the sealed cups must finally be manually placed in a storage area. This method is time-consuming, labor-intensive, and significantly reduces work efficiency.

A heat sealing limiting rod is provided below the heat sealing lifting seat, and there is a gap between the heat sealing limiting rod and the heat sealing plate.

[0013] Furthermore, the plastic cup feeding mechanism includes a worktable and a turntable disposed on the worktable. A rotating shaft is provided between the center of the turntable and the worktable. The surface of the turntable is provided with a plurality of plastic cup placement seats for placing plastic cups. A plurality of plastic cup placement slots are provided on the plastic cup placement seats. A sealing film placement slot is provided above the plastic cup placement slot. The sealing film placement slot is slightly larger than the plastic cup placement slot.

[0014] Compared with the prior art, the present invention has the following advantages: The device has a simple structure, is easy to use, and saves time and effort. When filling, the plastic cup is placed in the plastic cup placement slot of the plastic cup placement seat. The turntable drives the plastic cup placement seat to move to the bottom of the filling component. Each filling head is aligned with the plastic cup in each plastic cup placement slot. At this time, each peristaltic pump is started to quantitatively input the liquid in the liquid supply tank into the plastic cup, thereby completing the filling. This method saves time and effort, and the filling liquid volume is stable, which greatly improves work efficiency.

[0015] When filling plastic cups with liquid and fitting sealing film, multiple layers of sealing film are placed in the sealing film storage compartment. When the plastic cup placement seat moves below 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 cup takes out the bottom layer of sealing film through the sealing film retrieval port. The flipping cylinder drives the flipping shaft to rotate, causing the film-retrieving suction cup 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 groove. Then the telescopic cylinder drives the film-retrieving suction cup to approach the sealing film placement groove, the film-retrieving suction cup is released, and each sealing film falls into the sealing film placement groove of the plastic cup placement seat.

[0016] During the heat sealing process of the sealing film and plastic cup, the plastic cup is placed in the plastic cup placement slot on the plastic cup placement seat, and the sealing film is placed in the sealing film placement slot. The sealing film is pressed against the opening above the plastic cup. The heat sealing cylinder drives the heat sealing lifting seat, heat sealing plate, and heat sealing head to move downwards simultaneously, so that the heat sealing head extends into the sealing film placement slot and heat seals the sealing film onto the plastic cup, thus forming a whole. During the heat sealing process, when the heat sealing head contacts the sealing film and is pressed downwards, the spring can buffer the heat sealing plate and heat sealing head.

[0017] After the heat-sealing assembly heat-seales the plastic cup and sealing film together in the plastic cup holder, the sealed plastic cup needs to be output. The plastic cup feeding mechanism drives the plastic cup to rotate to the position of the discharge assembly. The longitudinal telescopic cylinder drives the discharge plate and discharge suction cup to move downward and pick up the plastic cup. The longitudinal telescopic cylinder resets, and the plastic cup is released from the plastic cup holder. The lateral telescopic cylinder drives the discharge longitudinal telescopic assembly and the plastic cup to move laterally, so that the plastic cup moves closer to the discharge plate. When the plastic cup moves to above the input end of the discharge plate, the discharge suction cup releases the plastic cup, so that the plastic cup is transported along the discharge plate to the goods storage area.

[0050] 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.

[0051] 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.

[0052] 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.

[0061] 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.

[0065] During operation: After the heat sealing assembly heat seals the plastic cup and sealing film together in the plastic cup holder, the plastic cup feeding mechanism drives the plastic cup to rotate to the position of the discharge assembly. The longitudinal telescopic cylinder drives the discharge plate and discharge suction cup to move downward and suck up the plastic cup. The longitudinal telescopic cylinder resets, and the lateral telescopic cylinder drives the discharge longitudinal telescopic assembly and plastic cup to move laterally, so that the plastic cup moves closer to the discharge plate. When the plastic cup moves to above the input end of the discharge plate, the discharge suction cup releases the plastic cup, so that the plastic cup is transported along the discharge plate to the goods storage area.
