Not only is the movement of the film not guided, but the separation between the film and the object is not neat. In addition, the film is not effectively pressed during the cutting process, resulting in low cutting efficiency. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An optical film tearing mechanism comprises a frame, a lifting frame is fixedly installed on the top of the frame, a U-shaped frame is provided on one side of the lifting frame, a U-shaped plate is fixedly connected to one side of the lifting frame, and the U-shaped frame is located in the U-shaped plate, and a cutter is provided under the U-shaped plate, and the film material can be cut by the cutter; it also includes a clamping component, and the clamping component is located in the U-shaped frame, and one end of the film material can be clamped by the clamping component; it also includes a lifting component, and the lifting component can drive the clamping component to move up and down, so as to pull one end of the film material, tear the film, and make it easier to cut the film material at the required position.

[0008] In one possible design, the clamping assembly includes a base plate fixedly connected to one side of the U-shaped frame, a pressure plate slidably connected in the U-shaped frame, and the pressure plate and the base plate are close together to clamp one end of the film material, a second screw rod is rotatably connected in the U-shaped frame, a second drive motor is fixedly connected in the U-shaped frame, and the output shaft of the second drive motor is fixedly connected to the bottom end of the second screw rod, and the second screw rod thread passes through the pressure plate, and the rotation of the second screw rod can drive the pressure plate to move up and down in the U-shaped frame, and the film material can be torn by moving upward.

[0009] In a possible design, the lifting assembly includes a third screw rod rotatably connected to the lifting frame, a second nut is slidably connected to the lifting frame, and the second nut is threadedly sleeved on the third screw rod, a third drive motor is fixedly connected to the top of the lifting frame, and one end of the output shaft of the third drive motor is fixedly connected to the top of the third screw rod, two connecting sliders are slidably connected to the lifting frame, and one side of the U-shaped frame and the second nut are fixedly connected to the two connecting sliders.

[0010] In a possible design, a first screw rod is rotatably connected inside the U-shaped plate, a first drive motor is fixedly connected inside the U-shaped plate, and one end of the output shaft of the first drive motor is fixedly connected to one end of the first screw rod, the first screw rod can be driven to rotate by the output shaft of the first drive motor, a first nut is slidably connected inside the U-shaped plate, and the first nut is threadedly sleeved on the outer wall of the first screw rod, the cutter is fixedly installed on the bottom of the first nut, and the movement of the first nut drives the cutter to cut the film material.

[0011] In a possible design, a pressure roller is provided under the U-shaped plate, which can guide the movement of the film material. Two electric push rods are fixedly connected inside the U-shaped plate, and one end of the output shafts of the two electric push rods are fixedly connected to the two ends of the pressure roller through a connecting seat and a connecting roller. The height of the pressure roller can be adjusted by telescopically moving one end of the output shaft of the electric push rod, and the torn part of the film material can be pressed to facilitate cutting by the cutter.

[0012] In one possible design, a conveying structure is fixedly installed in the frame. The conveying structure is composed of a driving motor, a conveyor belt and three conveyor rollers, and the three conveyor rollers are arranged in a triangle. The output shaft of the driving motor in the conveying structure can drive one of the conveyor rollers to rotate. The three conveyor rollers are connected by the conveyor belt. The rotation of the conveyor belt can transport and move the objects to be torn off.

[0013] In the present application, first, the object to be torn off is placed on the conveyor belt, and the driving motor drives the conveyor roller to rotate, thereby driving the conveyor belt to send the film material into the working area of ​​the film tearing mechanism. In this process, the film material moves forward smoothly and continuously to prepare for the subsequent film tearing operation. When the film material reaches the predetermined position, one end of the film body passes through one side of the pressure roller and is placed between the pressure plate and the bottom plate. The second drive motor output shaft drives the second screw rod to rotate, and the second screw rod is threaded into the thread groove of the pressure plate. Through the cooperation of the second screw rod and the pressure plate thread groove, the bottom plate fixedly connected to one side of the mechanism is driven to cooperate with the pressure plate slidably connected to the U-shaped frame to clamp one end of the film material. At this time, the clamping force is moderate to ensure that the film material will not slip or be damaged during the film tearing process. Next, the lifting component begins to play a role, and by rotating the third screw rod connected to the lifting frame The screw rod and the second nut threadedly connected to the third screw rod work together, and the clamping assembly moves in the vertical direction. This movement drives one end of the clamped film material to be torn upward, thereby achieving preliminary separation of the film material. In the process of the film material being torn, the pressure roller arranged under the U-shaped plate guides the movement of the film material to ensure that the film material remains stable during the film tearing process. The height of the pressure roller can be adjusted by telescopic movement of the output shaft of the electric push rod, and the torn part of the film material can be pressed, which helps the cutter to cut the film more accurately. During cutting, the cutting assembly in the U-shaped plate starts to work, and the first screw rod connected to the U-shaped plate is driven to rotate by the output shaft of the first drive motor. At the same time, the first nut slides along its outer wall driven by the first screw rod, and the cutter fixedly installed at the bottom of the first nut cuts the film material to ensure the accuracy and efficiency of the film tearing process.

[0014] Beneficial effects:

[0015] In the utility model, the optical film tearing mechanism can also guide and press the film, further improving the film tearing quality and efficiency. The pressure roller can guide the movement of the film material to ensure that the film material remains stable during the film tearing process. By adjusting the height of the pressure roller, the torn part of the film material is pressed, which helps the cutting assembly cutter to cut the film material more accurately.

[0016] In the utility model, the optical film tearing mechanism realizes the automatic film tearing operation of the film material through the coordinated work of the clamping component and the lifting component. The clamping component can accurately clamp one end of the film material, and the lifting component can drive the clamping component to move up and down, thereby realizing the pulling and tearing of the film material. This design not only improves the film tearing efficiency, but also reduces the difficulty of operation, and reduces the error and labor intensity of manual operation;

[0017] In the utility model, the film can be automatically torn off by the coordinated use of the clamping assembly and the lifting assembly, and the film material being transported can be guided and pressed by adjusting the height of the pressure roller, which can ensure greater stability during the film tearing process and more accurate film cutting.
