[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1 and Figure 2 , a Y-shaped cutting device, comprising:

[0024] Knife holder 7;

[0025] Y-shaped knife 8, the Y-shaped knife 8 is installed on the knife seat 7, the knife seat 7 is connected to the knife seat motor 6, the knife seat 7 is connected to the sheath 9, the sheath 9 is parallel to the knife seat 7 and the distance is only 5-15mm;

[0026] The ruler 14 is installed at the front end of the Y-shaped knife 8. The Y-shaped knife 8 is provided with a movable joint 15. The ruler 14 is used to clamp the running film. The distance between the film and the ruler 14 is 0.5-1mm;

[0027] A speed sensor 16 is installed on the knife seat 7, which is connected to a controller 17 and a meter 18. The speed sensor 16 is used to receive the running speed of the film in the winding system of the production line. One end of the connecting rod 12 is connected to a connecting sleeve 13, and the outer side of the connecting rod 12 is connected to a connecting rod 4. One end of the lead screw 3 is connected to a reducer 2, and the reducer 2 is connected to a motor 1. The motor 1 is used to drive the reducer 2 and the lead screw 3 to run. A threaded hole is provided on the connecting rod 4, and the lead screw 3 is threadedly connected to the threaded hole. The bottom of the connecting rod 4 is connected to a limit switch 5. One side of the knife seat 7 is connected to a connecting rod 12, and the connecting rod 12 is connected to a slide 11, and the slide 11 is connected to a slide seat 10.

[0028] The implementation principle of a Y-type cutting knife device in the embodiment of the present application is as follows: the optical film production line is running, and the motor 1 is running at the same time. The motor 1 drives the reducer 2 and the lead screw 3 to run, and the connecting rod 4 with a threaded connection with the lead screw 3 at the bottom is pushed forward. The controller 17 in the knife seat 7 installed on the connecting rod 12 is connected to the control system on the winder on the production line. The speed sensor 16 receives the running speed of the film in the winding system of the production line. The meter 18 calculates the size and weight of each roll of film according to the data transmitted by the speed sensor 16. According to the standard requirements, the meter 18 transmits the specified specifications of the cut film to the Y-type knife 8. The ruler 14 installed on the Y-type knife 8 clamps the running film. The Y-type knife 8 runs horizontally against the running film under the traction of the linear motion. At this time, the Y-type knife 8 cuts the film. The knife seat motor 6 drives the knife seat 7 to run. After cutting the running film in the horizontal operation, the Y-type knife 8 retreats. When it retreats to the limit switch 5, the Y The mold knife 8 stops running, and the slide plate 10 installed on the slide seat 10 clamps the connecting rod 12, so that the connecting rod 12 cannot run. When the connecting rod 12 runs linearly, the slide seat 8 plays the role of transmitting torque, adjusting clearance and clamping. The slide seat 10 and the connecting sleeve 13 have the same function.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
