The utility model provides a film tearing machine 100, which is used to tear off the protective film on the surface of the optical film material, which specifically includes:

Tear film member 10, aforesaid tear film member 10 comprises the protective film rotating shaft 11 that connects optical film material protection film and the first driving motor that connects protective film rotating shaft 11, and described first driving motor drives protective film rotating shaft 11 to rotate, to The protective film is rolled on the protective film rotating shaft 11; and the bracket 20 is used for supporting the tearing film member 10 and the optical film material.

The utility model drives the protective film to separate from the surface of the optical film material through the rotatable protective film rotating shaft 11 .

Referring to shown in Fig. 1, in one embodiment of the present utility model, tear film member 10 also comprises adhesive tape output shaft 12, and is arranged on adhesive tape output shaft 12 and the adhesive tape that winds through protective film rotating shaft 11, and adhesive tape is used for adhesive protection membrane.

In particular, the film tearing machine includes two separate film tearing members 10, through the cooperation of the two film tearing members 10, the upper protective film and the lower protective film of the optical film material can be torn off synchronously.

Wherein, adhesive tape is an adhesive tape roll, and its main part is arranged on the adhesive tape output shaft 12, and can rotate around adhesive tape output shaft 12, and adhesive tape extends from main part, and winds on the protective film rotating shaft 11.

The adhesive tape moves through the cooperating rotation of the adhesive tape output shaft 12 and the protective film rotating shaft 11, thereby driving the protective film bonded by the adhesive tape to move, so that the protective film is detached from the surface of the optical film material.

The utility model respectively bonds the upper protective film and the lower protective film of the optical film material through two adhesive tapes in the two tearing film members 10, so as to simultaneously tear off the upper protective film and the lower protective film of the optical film material, thereby improving the tearing film efficiency and precision.

Specifically, the tearing film member 10 includes a first drive motor and a second drive motor respectively connected to the protective film rotating shaft 11 and the tape output shaft 12, and the first drive motor and the second drive motor cooperate to control the protection film. The film rotating shaft 11 and the tape output shaft 12 rotate, thereby driving the tape to move, which facilitates the subsequent film tearing process.

Wherein, the driving force of the rotating shaft provided by the first driving motor is the main driving force, and the aforementioned protective film rotating shaft 11 rotates to take up the adhesive tape. The driving force of the rotating shaft is to also drive the tape output shaft 12 to rotate, so that the tape is continuously replenished, thereby meeting the needs of the industrial preparation process.

In particular, the second drive motor controls the tape output shaft 12 to rotate in the direction opposite to the protective film shaft 11, that is, the second drive motor provides tension in the direction opposite to the direction of the shaft driving force provided by the first drive motor. , the magnitude of the tension is much smaller than the driving force of the aforementioned rotating shaft, thereby not affecting the movement of the adhesive tape from the adhesive tape output shaft 12 to the protective film rotating shaft 11, and at the same time, the tension also enables the adhesive tape to maintain a certain degree of tightness during the moving process, improving the The adhesion between the adhesive tape and the protective film on the surface of the optical film material enables the protective film to follow the adhesive tape and move to the protective film rotating shaft 11 smoothly, thereby completing the film tearing process.

The tearing film member 10 includes a stripping plate 17 to resist the protective film of the optical film material. Specifically, the stripping plate 17 is in the same number as the tearing film member 10, and is also set to two.

The stripping plate 17 is arranged on the moving path of the optical film, and the upper protective film or the lower protective film are supported by the aforementioned two stripping plates 17 during the moving process.

Specifically, the stripping plate 17 squeezes the protective film towards the main material layer of the optical film material, and in the process of tearing the protective film off the optical film material, it moves away from the main material layer of the optical film material. Therefore, the stripping plate 17 can Define the position where the protective film is initially detached from the optical film material to improve the efficiency and accuracy of tearing off the upper or lower protective film.

The film tearing machine 100 also includes a pressing roller 16, which presses the protective film of the optical film material, so that the protective film has a certain degree of tension during the film tearing process, making the film tearing process easier.
