[0025] The utility model provides a film tearing device. When the edge of the film to be torn has a fixed sheet extending outward, the first rotating driving member 4 drives the first clamping jaw driving member 42 to move so that the fixed sheet is located between the first clamping jaws 421. Then the first clamping jaw driving member 42 drives the first clamping jaw 421 to clamp the fixed sheet. Finally, the first rotating driving member 4 drives the first clamping jaw 421 to rotate to separate the film to be torn, thereby completing the film tearing action. When the film to be torn does not have a fixed sheet extending outward, the first rotary drive member 4 drives the second clamping jaw drive member 44 to move, so that the driving path of the first linear drive member 45 corresponds to the edge position of the film to be torn, and then the first linear drive member 45 drives the adhesive roller 452 to move to the edge position of the film to be torn and fit with the film to be torn. After fitting, the first linear drive member 45 drives the adhesive roller 452 to move a certain distance away from the film to be torn, so that the edge position of the film to be torn is tilted, and then the second clamping jaw drive member 44 drives the second clamping jaw 441 to rotate so that the second clamping jaw 441 clamps the tilted part of the film to be torn, and finally the first linear drive member 45 drives the adhesive roller 452 to separate from the film to be torn, and at the same time, the first rotary drive member 4 drives the second clamping jaw 441 to rotate to separate the film to be torn, thereby completing the film tearing action. The film tearing mode can be switched by the first rotary drive member 4, thereby improving the speed of switching the film tearing mode and thereby improving the film tearing efficiency.

[0026] The first rotary driving member 4 is a motor. The output end of the first rotary driving member 4 is connected to a first connecting plate 41 . The first connecting plate 41 is arranged vertically to the film to be torn.

A pair of first clamping jaws 421 are connected to the output end of the first clamping jaw driving member 42, and the first clamping jaw driving member 42 can drive the first clamping jaw 421 to move in a straight line in a direction close to or away from each other, thereby completing the clamping and releasing action of the first clamping jaw 421. Preferably, the clamping surface of the first clamping jaw 421 is serrated, so that the film to be torn is not easy to fall off when clamped by the first clamping jaw 421. The first clamping jaw driving member 42 is connected to the second linear driving member 43 through the second mounting frame 432, and the output end of the second linear driving member 43 is connected to the pressing block 431, which is cylindrical as a whole, and the second linear driving member 43 can drive the pressing block 431 to move in a direction to one side of the clamping end of the first clamping jaw 421. The first clamping jaw 421 can also clamp the tape so that a part of the tape is bonded to the film to be torn off, and the second linear driving member 43 drives the pressing block 431 to move toward the bonding part between the tape and the film to be torn off, so that the tape and the film to be torn off are stably bonded, and the first rotating driving member 4 drives the first clamping jaw 421 to rotate, and the first clamping jaw 421 drives the tape to move so that the film to be torn off.

A pair of second jaws 441 are connected to the output end of the second jaw driving member 44, and the second jaw driving member 44 can drive the second jaws 441 to rotate in a direction close to or away from each other, thereby completing the clamping and releasing action of the second jaws 441. Preferably, the clamping surface of the second jaw 441 is serrated, so that the film to be torn is not easy to fall off when clamped by the second jaw 441. One side of the second clamping jaw driving member 44 is connected to a first linear driving member 45, which is a cylinder.

The first linear driving member 45 can drive the sticky roller 452 to move along the plane where the clamping surface of the second clamping jaw 441 is located when the second clamping jaw 441 is in the clamping state, so that after the first linear driving member 45 drives the sticky roller 452 to tilt the edge position of the film to be torn, the tilted position can be located between the second clamping jaws 441. The second clamping jaw 441 can rotate to complete the clamping and releasing actions, so that the second clamping jaw 441 has a larger opening angle when it is released. When the first linear driving member 45 drives the sticky roller 452 to tilt the edge position of the film to be torn, the second clamping jaw 441 will not hinder the tilted position of the film to be torn from moving toward the clamping position of the second clamping jaw 441.
