The adhesive layer on the narrow and long tape is adhesively connected to the release film, and it includes: a machine table, a rotating shaft rotatably installed on the machine table, one end of a supporting cross bar is connected to the upper end of the rotating shaft, and the other end is provided with a vertical cylinder with a movable part provided with a connecting plate, and a jaw cylinder is installed on this connecting plate. The two clamping parts of the jaw cylinder are used for clamping and cooperating with the release film.

[0006] The further improved schemes in the above technical scheme are as follows:

[0007] 1. In the above scheme, a bushing is arranged between the rotating shaft and the machine table, and the bushing is fixedly connected to the machine table.

[0008] 2. In the above scheme, a bearing matching with the rotating shaft is arranged inside the bushing.

[0009] 3. In the above scheme, a rotating motor for driving the rotating shaft to rotate is arranged at the bottom of the bushing.

[0010] 4. In the above scheme, each of the two clamping parts is connected with a strip-shaped jaw, and the two strip-shaped jaws are arranged oppositely.

[0011] 5. In the above scheme, a limiting strip is arranged on the side wall of the cylinder, and the connecting plate has a sliding groove matching with the limiting strip.

[0012] Due to the application of the above technical scheme, the utility model has the following advantages compared with the prior art:

[0013] The film tearing mechanism of the present utility model is provided with a rotating shaft connected to a support cross bar on a machine table. One end of the support cross bar is connected to the upper end of the rotating shaft, and the other end is provided with a vertical cylinder with a movable part provided with a connecting plate. A jaw cylinder is installed on this connecting plate. The two clamping parts of the jaw cylinder are used for clamping and cooperating with the release film. After the release film is clamped by the clamping parts of the jaw cylinder, the rotating shaft drives the support cross bar to rotate, so as to drive the release film to fold and separate from the narrow tape, realizing the automatic tearing of the release film, avoiding the situation of tape damage caused by difficult control of manual force, and also reducing the labor intensity of personnel.
