Referring to fig. 1-2, the present invention provides a film cutting device 10. The film cutting apparatus 10 includes two lifting cylinders (first and second lifting cylinders) 15 as a driving assembly, a cross beam 14 connected between the two lifting cylinders 15, and a heating wire 12 connected to the cross beam 14. Each lifting cylinder 15 is fixedly connected to the fixed base 16 by means of two fixed plates 17 and bolts 18, and the fixed base 16 can be mounted on a corresponding part of the film sticking device, for example, the side support 24 of the film sticking device 20 shown in fig. 3. When the film cutting device 10 is not installed on the film sticking equipment to work with the film sticking equipment but works independently, the fixed seat 16 can be installed on a proper fixed member (fixture) in a manner suitable for the independent work of the film cutting device 10.

Both ends of the cross beam 14 are connected to the bottom ends of the two lifting cylinders 15, respectively, and both ends of the heating wire 12 are connected to the cross beam 14 at positions close to both ends through the connection blocks 13, respectively. The material of the lifting cylinder 15, the beam 14 and the connecting block 13 can be any suitable material, but since the working temperature of the heating wire 12 is usually high (e.g. 800 ℃), the lifting cylinder 15, the beam 14 and the connecting block 13 need to be resistant to high temperature, i.e. to work normally when the heating wire 12 is at the working temperature.

On the other hand, the structural configuration of the lifting cylinder 15, the cross beam 14 and the connecting block 13 may also be of any suitable design. The cross beam 14 is mainly used to stabilize the heater 12 and keep the heater in a straightened state during the whole working process.

The structural configuration and materials of the heater (i.e., heat-generating film cutting member) 12 are not particularly limited, except that it can be ensured that it can normally operate at the operating temperature. Because of the need to cut (blow) the film that joins the two pieces of glassware, the heater 12 is generally a wire-like structure that may have any suitable cross-sectional shape, such as circular, triangular, diamond-shaped, etc. The operating temperature of the heater 12 may be adjusted according to the film thickness of the film to be cut, the texture/material of the film, and the like.
