Description

Sealing film punching device and sealing machine with punching device

The invention relates to a production equipment, in particular to a sealing film punching device and a sealing machine with a punching device.

When vendors sell hand-cranked beverages, they often put the beverages in a beverage cup and use a mouthpiece to close the opening of the beverage cup. In addition, the merchant will also provide a straw so that customers can use the straw to pierce the sealing film and drink the beverage in the beverage cup. However, most of the straws currently used in the market are disposable and difficult to degrade in the environment. After being discarded, it is easy to damage the environment and may threaten the survival of the organisms in the environment. Therefore, in recent years, an environmentally friendly straw that has been easily degraded in the natural environment has also appeared. However, this environmentally friendly straw has a soft texture, so it will be difficult to puncture the sealing film when replacing the original straw.

Therefore, an object of the present invention is to provide a sealing film punching device and a sealing machine having the punching device, which make the processed sealing film easier to be punctured.

Therefore, the novel sealing film punching device is suitable for processing a piece of sealing film, and includes a shim, a movable rod, a blade, and a driving unit.

The blade is disposed at the first end of the movable rod and has a blade edge on a side adjacent to the blade pad and suitable for cutting. The driving unit is connected to the second end portion and drives the movable rod to move between a standby position and a cutting position. When the movable lever is in the prepared position, the movable lever is far away from the shim, the blade and the shim are spaced apart from each other and can collectively define a placement gap for the sealing film to pass through. When the movable lever is in the cutting position, the movable lever approaches the knife pad, and the blade is pressed against the knife pad, so that the knife edge cuts the sealing film.

The novel sealing machine with a perforating device comprises the perforating device for a sealing film, and is suitable for pressing a plurality of sealing films to a plurality of cups, respectively.
