[0024] Please see Figure 1This application provides a high-precision adhesive film cutting device 100, which includes a first roller 10, a winding device 20, a cutting device 30, a sensor 40, and an adhesive application device 50. The first roller 10 is used to transport the adhesive film 200. The winding device 20 includes a winding shaft 21 and a winding drum 22, which is sleeved on the outer periphery of the winding shaft 21 and used to wind up the transported adhesive film. The cutting device 30 is used to cut the adhesive film. The sensor 40 is used to sense the adhesive film and detect the amount of adhesive film transported. When the sensor 40 detects a preset amount of transport, it controls the cutting device 30 to cut the adhesive film and controls the winding device 20 to accelerate the winding speed. The adhesive application device 50 is used to apply adhesive to a new winding drum 22 after replacement; after cutting the adhesive film, the winding device 20 rotates, allowing the cut adhesive film to adhere to the adhesive on the winding drum 22.

[0025] The film cutting device 100 of this application effectively solves the problems of low precision and poor efficiency of traditional film cutting devices 100 by using a high-precision sensor 40 to precisely control the film transmission volume and cutting timing. This significantly improves cutting accuracy and production efficiency, and greatly reduces material waste and labor costs. At the same time, the design of the adhesive application device 50 ensures continuous operation when changing to a new roll take-up 22, providing greater convenience and economy.

[0026] Specifically, please refer to Figure 1 The film cutting device 100 includes a first roller 10, a winding device 20, a cutting device 30, a sensor 40, an adhesive application device 50, a pushing device 60, a second roller 70, and a transition plate 80.

[0027] After the adhesive film is produced, it is transported using a roller conveyor. After passing through the first roller 10, the adhesive film is wound up by a winding device 20. The winding device 20 includes a winding shaft 21 and a winding drum 22. The winding drum 22 is sleeved on the outer circumference of the winding shaft 21, and the winding shaft 21 drives the winding drum 22 to wind up the adhesive film. A power device (not shown) is externally connected to the winding shaft 21, which can control the rotation speed of the winding shaft 21, allowing it to stop and start immediately, etc. The winding shaft 21 rotates clockwise. In the embodiments of this application, the center lines of the first roller 10 and the winding drum 22 are set in the same vertical direction, and the diameter of the winding drum 22 is larger than the diameter of the first roller 10, so that the cut adhesive film adheres to the winding drum 22 under its own weight. In other practical methods, the same effect can be achieved by offsetting the winding shaft 21 relative to the vertical plane where the first roller 10 is located.

[0028] Please combine Figure 2The cutting device 30 includes a cutting motor 31 and a cutter 32. The cutter 32 is mounted on the output shaft of the cutting motor 31. The output shaft of the cutting motor 31 can quickly extend and retract outwards, rapidly pushing the cutter 32 towards the adhesive film to cut the film, and then retracting the cutter 32. The length direction of the cutter 32 is the same as the width direction of the adhesive film, and the length of the cutter 32 is greater than or equal to the width of the adhesive film.

[0029] Sensor 40 is positioned on the transmission path between the first roller 10 and the take-up device 20. Sensor 40 can be used to detect whether the adhesive film is on the transmission path and to detect the transmission speed of the adhesive film. Based on this speed, the amount of adhesive film transmitted, i.e., the length of the adhesive film, can be calculated. Sensor 40 can be an infrared sensor 40, a laser displacement sensor 40, a photoelectric sensor 40, etc.

[0030] Please combine Figure 3 The adhesive applicator 50 is used to apply adhesive to the take-up drum 22. After the take-up drum 22 winds up a certain length of adhesive film according to preset requirements, the cutting device 30 cuts the adhesive film and quickly replaces the take-up drum 22. Then, the adhesive applicator 50 begins applying adhesive to the newly replaced take-up drum 22 to ensure that the adhesive film can be stably adhered to the take-up drum 22. Specifically, the adhesive applicator 50 includes an adhesive applicator telescopic motor 51 and an adhesive block 52. The adhesive block 52 is mounted on the output shaft of the adhesive applicator telescopic motor 51 and has adhesive applied to it. The adhesive applicator telescopic motor 51 drives the adhesive block 52 to push it towards the take-up drum 22, allowing the adhesive to adhere to the take-up drum 22.

[0031] In embodiments of this application, the adhesive block 52 includes a receiving cavity 521, an adhesive-attaching block 522, and an adhesive-blocking block 523. The receiving cavity 521 is used to hold the adhesive. The adhesive-attaching block 522 communicates with the receiving cavity 521 and is made of a permeable material such as sponge, allowing the adhesive to permeate onto it. The adhesive-blocking blocks 523 are located on both sides of the adhesive-attaching block 522 and are used to prevent adhesive leakage when the adhesive-attaching block 522 applies adhesive to the take-up drum 22. The adhesive-blocking blocks 523 are made of an elastic material, such as rubber or thermoplastic materials.

[0032] In one embodiment, the surface of the adhesive block 523 that contacts the take-up drum 22 is configured as a curved surface 524 corresponding to the take-up drum 22, so that the adhesive block 523 can better adhere to the take-up drum 22. The lengths of the adhesive block 522 and the adhesive block 523 are the same as the width of the adhesive film. In other embodiments, simply installing the adhesive block 522 can also complete the adhesive application to the take-up drum 22, and the lengths of the adhesive block 522 and the adhesive block 523 can be less than the width of the adhesive film. Alternatively, multiple dispensing methods can also be used to ensure that the adhesive film adheres to the take-up drum 22.

[0033] Please combine Figure 1 and Figure 4 After the adhesive film contacts the adhesive on the take-up drum 22, the pushing device 60 presses the adhesive film against the take-up drum 22, so that the adhesive film can be stably attached to the take-up drum 22. In the embodiment of this application, the pushing device 60 and the take-up shaft 21 are arranged on the same horizontal plane. Specifically, the pushing device 60 includes a pushing telescopic motor 61 and a pressing block 62. The pressing block 62 is mounted on the output shaft of the pushing telescopic motor 61, and the output shaft and the take-up shaft 21 are located on the same plane. The pressing block 62 is provided with an arc surface 621 corresponding to the axial surface of the take-up drum 22. The pushing telescopic motor 61 pushes the arc surface 621 to press the adhesive film, so that the pushing block can adhere to the take-up drum 22.

[0034] Please see Figure 1 The second roller 70 is located above the first roller 10. A pressure shaft 71 is positioned above the second roller 70, and the pressure shaft 71 uses its own weight to press the adhesive film. The adhesive film is transferred from the second roller 70 to the first roller 10 and then to the take-up device 20. A transition plate 80 is provided between the first roller 10 and the second roller 70, and the surface of the transition plate 80 is tangent to both the first roller 10 and the second roller 70. The transition plate 80 has an arc-shaped surface that corresponds to the axial surface of the abutment shaft of the first roller 10 and the second roller 70, allowing the transition plate 80 to fit tangentially with the first roller 10 and the second roller 70.

[0035] The transition plate 80 is provided with a platform 81 corresponding to the cutting device 30, and the platform 81 is provided with a cut 811 corresponding to the cutter 32. That is to say, the cutting device 30 is installed at a position corresponding to the surface of the transition plate 80. The surface of the transition plate 80 is inclined relative to the horizontal plane so that after the film is cut, it can adhere to the surface of the plate by its own weight without changing the original transmission channel. In one embodiment, the film cutting device 100 also includes an arc-shaped traction plate 11, which is located on the outer periphery of the first roller 10, and is used to enable the cut film to be transmitted along the original path.

[0036] The working principle of the film cutting device 100 of this application is as follows: When the sensor 40 detects that the film wound by the take-up cylinder 22 has reached the preset length, the cutting device 30 is controlled to cut the film on the transition plate 80. At the same time, the take-up device 20 increases the rotation speed of the take-up cylinder 22 to take up the film. After that, the finished film is unwound and a new take-up cylinder 22 is installed. At this time, the take-up shaft 21 is fixed, and the adhesive application device 50 pushes the adhesive application block 522 to apply adhesive to the take-up cylinder 22. After the sensor 40 detects the new cut film, the sensor 40 sends a signal to start the take-up device 20, so that when the film contacts the take-up shaft 21, the adhesive application position is exactly in contact with the film. At this time, the winding device 20 continues to rotate. After receiving the signal, the pushing device 60 pushes out the extrusion block 62 (when the adhesive film and the adhesive coating rotate to the horizontal position) according to the preset time to extrude the adhesive film, so that the adhesive film can be attached to the winding drum 22 at the temperature. The winding drum 22 completes the winding work normally, and then the cycle continues.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the stated features. In the description of this application, "multiple" means at least two, such as two or three, unless otherwise explicitly specified.
