To this end, embodiments of this invention provide a film peeling device, which can solve the problems in the prior art where the equipment is easily affected by external forces and is prone to misoperation, and is inconvenient for material unloading.

[0005] This utility model embodiment provides a film peeling device, including a frame and a film separating assembly. The frame is U-shaped with an upper opening. The film separating assembly includes an input roller and a film separating roller. Two sets of the input rollers are symmetrically arranged vertically between the two free ends of the frame. Two sets of film separating rollers are symmetrically arranged vertically between the two free ends of the frame. The device also includes:

[0006] A winding assembly includes a motor, a first worm, a first worm wheel, a bracket, a second worm wheel, a second worm, a winding roller, and a support cover. A U-shaped bracket is provided on the outer side of a free end of the frame. The opening of the bracket is located at the end away from the parting assembly. The support cover is located at the center of the side wall of the bracket. The first worm and the first worm wheel are disposed inside the support cover. The output end of the motor passes through the support cover and is connected to the first worm. The first worm meshes with the first worm wheel. Second worms are symmetrically arranged on the upper and lower sides of the support cover. One end of the second worm passes through the support cover and is connected to the center of the first worm wheel. The other end of the second worm is rotatably connected to the free end of the bracket. A second worm wheel meshing with the second worm is also provided on the side wall of the bracket. The winding roller passes through a free end of the frame and the bracket and is connected to the center of the corresponding second worm wheel.

[0007] The take-up roller is also equipped with an adjustment component.

[0008] According to the film peeling device provided in this embodiment of the present invention, the adjusting assembly includes a positive and negative threaded screw, a movable disk, a first hinge seat, a second hinge seat, a hinge rod, an adjusting plate, a roller sleeve, and a handle. The parting roller has a movable cavity at its center. The positive and negative threaded screw and two sets of symmetrically arranged movable disks are rotatably arranged in the movable cavity. The center of the movable disk is threadedly connected to the positive and negative threaded screw. The take-up roller is also provided with a sliding hole penetrating the movable cavity. The movable disk is provided with a first hinge seat penetrating the sliding hole. A second hinge seat is also provided below the adjusting plate. The two ends of the hinge rod are respectively hinged to the first hinge seat and the second hinge seat. The inner wall of the roller sleeve is in contact with several sets of adjusting plates. The positive and negative threaded screw passes through the take-up roller and is connected to the handle.

[0009] According to the film peeling device provided in the embodiment of this utility model, the other free end of the frame is also provided with a notch adapted to the winding roller portion.

[0010] According to the film peeling device provided in this embodiment of the present invention, the motor is a servo motor.

[0011] According to the film peeling device provided in the embodiment of this utility model, the handle is provided with friction texture.

[0012] According to the film peeling device provided in the embodiment of this utility model, the adjusting plate is in the shape of an inverted triangle with the opening away from the take-up roller, and the roller sleeve is disposed between the two free ends of the adjusting plate.

[0013] The film peeling device provided according to the embodiments of this utility model has at least the following beneficial effects:

[0014] This film peeling device employs a motor-driven first worm gear in its winding assembly. The first worm gear meshes with a first worm wheel, which in turn drives the winding roller through a second worm gear and a second worm wheel. This worm gear transmission structure is self-locking, meaning that only the worm can drive the worm wheel, but the worm wheel cannot drive the worm. This effectively prevents the gear structure from being misdriven due to external forces during operation, ensuring the stability and reliability of the winding process and allowing the film peeling experiment to proceed smoothly.

[0015] The adjustment assembly, through the cooperation of components such as threaded screws, movable discs, hinge rods, and adjustment plates, achieves adjustment of the roller sleeve. When the handle is turned to rotate the threaded screws, the movable discs, being threadedly connected to the screws, cause the two sets of movable discs to move relative to or away from each other. The movable discs are connected to the adjustment plate via a first hinge seat, a hinge rod, and a second hinge seat. The movement of the movable discs causes the adjustment plate to rotate around the hinge point, thereby changing the contact state between the adjustment plate and the roller sleeve. When material removal is required, turning the handle separates the adjustment plate from the roller sleeve, allowing the film to be easily removed from the roller sleeve, solving the problem of inconvenient material removal in existing technologies and improving work efficiency.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figures 1-5 A film peeling device includes a frame 1 and a film separating assembly. The frame 1 is an open-top C-shaped assembly. The film separating assembly includes input rollers 2 and film separating rollers 3. Two sets of input rollers 2 are symmetrically arranged vertically between the two free ends of the frame 1, and two sets of film separating rollers 3 are symmetrically arranged vertically between the two free ends of the frame 1. The device also includes:

[0028] The frame 1 is an open-top C-shape, providing support and a mounting base for the entire device. Two sets of symmetrically arranged input rollers 2 are installed between the two free ends of the frame 1, and their function is to guide and transport the optical film into the device. Driven by the input rollers 2, the film can smoothly enter the subsequent film separation stage;

[0029] The two component film rollers 3, which are also installed symmetrically between the two free ends of the frame 1, are responsible for separating the input film.

[0030] The winding assembly includes a motor 4, a first worm 5, a first worm wheel 6, a bracket 7, a second worm wheel 8, a second worm 9, a winding roller 10, and a support cover 11. A C-shaped bracket 7 is provided on the outer side of a free end of the frame 1. The opening of the bracket 7 is located at the end away from the parting assembly. A support cover 11 is provided at the center of the side wall of the bracket 7. The first worm 5 and the first worm wheel 6 are provided inside the support cover 11. The output end of the motor 4 passes through the support cover 11 and is connected to the first worm 5. The first worm 5 meshes with the first worm wheel 6. The second worm 9 is symmetrically arranged on the upper and lower sides of the support cover 11. One end of the second worm 9 passes through the support cover 11 and is connected to the center of the first worm wheel 6. The other end of the second worm 9 is rotatably connected to the free end of the bracket 7. A second worm wheel 8 that meshes with the second worm 9 is also provided on the side wall of the bracket 7. The winding roller 10 passes through a free end of the frame 1 and the bracket 7 and is connected to the center of the corresponding second worm wheel 8.

[0031] After the motor 4 starts, its output end passes through the support cover 11 and drives the first worm 5 to rotate. Because the first worm 5 meshes with the first worm wheel 6, the rotation of the first worm 5 will drive the first worm wheel 6 to rotate synchronously. The center of the first worm wheel 6 is connected to the second worm 9, and the rotation of the first worm wheel 6 causes the second worm 9 to rotate as well. One end of the second worm 9 passes through the support cover 11 and is connected to the center of the first worm wheel 6, and the other end is rotatably connected to the free end of the bracket 7, providing a stable support structure for the rotation of the second worm 9. The second worm wheel 8 set on the side wall of the bracket 7 meshes with the second worm 9, and the rotation of the second worm 9 drives the second worm wheel 8 to rotate. The take-up roller 10 passes through one free end of the frame 1 and the bracket 7, and is connected to the center of the corresponding second worm wheel 8. Therefore, the rotation of the second worm wheel 8 will cause the take-up roller 10 to rotate. Because the worm gear transmission structure has a self-locking characteristic, that is, only the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate. This ensures that after the motor 4 stops driving, the winding roller 10 will not rotate erroneously due to external forces, thus ensuring the stability and reliability of the winding process, enabling the film to be wound according to the predetermined requirements, and ensuring the smooth progress of the film peeling experiment.

[0032] An adjustment component is also provided on the take-up roller 10.

[0033] The adjustment assembly includes a threaded screw 12, a movable disc 13, a first hinge seat 14, a second hinge seat 15, a hinge rod 16, an adjustment plate 17, a roller sleeve 18, and a handle 19. The parting roller has a movable cavity at its center. Within the movable cavity, the threaded screw 12 and two symmetrically arranged movable discs 13 are rotatably mounted. The center of each movable disc 13 is threadedly connected to the threaded screw 12. The take-up roller 10 also has a sliding hole penetrating the movable cavity, and the movable discs 13 have a first sliding hole penetrating the sliding hole. A hinge seat 14 is provided, and a second hinge seat 15 is also provided below the adjusting plate 17. The two ends of the hinge rod 16 are respectively hinged to the first hinge seat 14 and the second hinge seat 15. The inner wall of the roller sleeve 18 is in contact with several sets of adjusting plates 17. The positive and negative threaded screw 12 passes through the take-up roller 10 and is connected to the handle 19. When it is necessary to take up the film, the operator turns the handle 19, and the handle 19 is connected to the positive and negative threaded screw 12, thereby driving the positive and negative threaded screw 12 to rotate in the movable cavity at the center of the parting roller. Since the center of the moving disk 13 is threadedly connected to the positive and negative threaded screw 12, and the positive and negative threaded screw 12 has a positive and negative thread structure, the rotation of the positive and negative threaded screw 12 will drive the two sets of moving disks 13 to move relative to each other. The moving disk 13 is provided with a first hinge seat 14 that passes through the sliding hole of the take-up roller 10. The second hinge seat 15 is provided below the adjusting plate 17. The two ends of the hinge rod 16 are respectively hinged to the first hinge seat 14 and the second hinge seat 15. When the movable disk 13 moves relative to the hinge, the adjusting plate 17 rotates around the hinge point via the transmission of the hinge rod 16. The adjusting plate 17 is U-shaped with the opening away from the take-up roller 10, and the roller sleeve 18 is disposed between the two free ends of the adjusting plate 17. After the adjusting plate 17 rotates, it will fit tightly against the roller sleeve 18. At this time, the rotation of the take-up roller 10 will drive the roller sleeve 18 to rotate together, thereby realizing the winding operation of the film.

[0034] When unloading is required, the operator reverses the handle 19, causing the positive and negative thread screws 12 to rotate in opposite directions, and the two sets of moving discs 13 to move in opposite directions. The opposite movement of the moving discs 13 causes the adjusting plate 17 to rotate in opposite directions around the hinge point via the hinge rod 16, separating the adjusting plate 17 from the roller sleeve 18. At this time, the constraint between the film and the roller sleeve 18 is released, and the operator can easily remove the film from the roller sleeve 18, completing the unloading process.

[0035] A notch at the other free end of the frame 1 that is adapted to the take-up roller 10 facilitates the unloading of the roller sleeve 18.

[0036] The motor 4 is a servo motor, which has high-precision control performance and can accurately control the rotation angle and speed of the output shaft. In this device, the servo motor 4 precisely controls the rotation of the first worm gear 5, and thus precisely controls the rotation speed and number of rotations of the winding roller 10, ensuring the accuracy and consistency of the film winding process and meeting the precision requirements of the film peeling experiment for the winding operation.

[0037] The friction texture on the handle 19 increases the friction between the operator's hand and the handle 19, making the operation more stable and less prone to slippage, thus improving the convenience and accuracy of operation. Operators can more easily and accurately control the movement of the adjustment components, achieving effective control over film winding and unwinding.

[0038] In this embodiment, the adjusting plate 17 is U-shaped with the opening away from the take-up roller 10, and the roller sleeve 18 is disposed between the two free ends of the adjusting plate 17 to facilitate the positioning of the roller sleeve 18.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
