Description

Technical Field

[0001] This utility model relates to the technical field of automated manufacturing, and in particular to a protective film production winding device. Background Technology

[0002] In fields such as precision electronics manufacturing, semiconductor processing, and high-end building materials production, process protection film is widely used as a key auxiliary material for product surface protection. With the development of industrial materials towards composite and functionalization, new materials such as polyimide films with special coatings and multilayer co-extruded PE films are constantly emerging, which places higher demands on the protective film peeling process.

[0003] Traditional lever-type or fixed-angle peeling devices have revealed significant limitations in actual production: on the one hand, when faced with protective films with modified formulations such as added antistatic agents and tackifying resins, their constant peeling angle is difficult to match the viscoelastic properties of different materials, easily resulting in adhesive residue or substrate tearing; on the other hand, when switching between 0.025mm ultra-thin optical-grade PET film and 1.2mm thick industrial-grade PP film for cross-specification production, the adjustment range of the existing mechanical structure is insufficient, leading to frequent replacement of the peeling module, which seriously affects the continuous operation efficiency of the production line.

[0004] While the currently common 90° right-angle peeling solution meets basic requirements, it suffers from a high rate of film curling deformation (up to 15%) due to stress concentration when processing high-density cross-linked acrylic protective films, limiting the yield of finished products. Some manufacturers have attempted to use multi-link linkage mechanisms for fine-tuning the angle, but the complex transmission structure not only increases the risk of equipment failure, but its linear adjustment method also makes it difficult to accurately control the dynamic contact angle during the peeling process. Therefore, existing technologies require further improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a protective film production winding device to solve one or more problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective film production winding device, comprising: a frame body; an unwinding roller group and a finished film guide roller, rotatably mounted on the frame body; a peeling frame, one end of which is hinged to the frame body; a peeling roller, rotatably mounted on the peeling frame, forming an adjustable peeling angle with the finished film guide roller; and an adjustment mechanism, mounted on the frame body and drivenly connected to the other end of the peeling frame, for driving the peeling frame to swing around its hinged end to adjust the peeling angle.

[0007] In one embodiment of this utility model, the adjusting mechanism is an adjusting cylinder, the cylinder body of which is fixed on the main body of the frame, and the end of the piston rod is connected to the stripping frame.

[0008] In one embodiment of the present invention, the unwinding roller group includes at least one guide roller and two tension rollers arranged in parallel side by side, and the film to be peeled is sequentially wound around the guide roller and the tension rollers.

[0009] In one embodiment of the present invention, a synchronous transmission chain is connected between two tension rollers arranged side by side to achieve synchronous rotation of the two tension rollers.

[0010] In one embodiment of the present invention, the outer peripheral wall of the tension roller is provided with a textured structure, which is used to increase the friction between the roller and the film and improve the stability of tension control.

[0011] In one embodiment of this utility model, the texture structure is a serrated pattern, knurling, or mesh-like protrusion.

[0012] In one embodiment of this utility model, there are multiple guide rollers, which are arranged at intervals along the film conveying direction to achieve orderly guiding and conveying of the film.

[0013] In one embodiment of the present invention, a servo motor is further included. The servo motor is fixedly mounted on the frame body, and its output shaft is connected to the finished film guide roller for driving the finished film guide roller to rotate.

[0014] In one embodiment of the present invention, a support frame is further included, which is fixedly installed at the bottom of the frame body.

[0015] As described above, the protective film production winding device of this utility model has the following beneficial effects: By designing the peeling frame as a movable structure that can swing around the hinge point and equipped with an independent adjustment mechanism for drive, flexible and precise adjustment of the peeling angle between the peeling roller and the finished film guide roller is achieved. This allows the same device to actively adapt to the peeling process requirements of protective films with different viscosities, thicknesses, or materials, significantly improving the equipment's versatility and adaptability to diverse production tasks. It fundamentally solves the problems of incomplete film peeling, wrinkles, breakage, or damage to the surface of the finished film caused by the non-adjustable angle of fixed peeling mechanisms.

At the same time, the structure is compact, and the adjustment operation is intuitive and convenient. Attached Figure Description

[0019] This utility model provides a protective film production winding device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Please see Figure 1 This utility model provides a protective film production winding device, comprising: a frame body 1; an unwinding roller group 2 and a finished film guide roller 3, the unwinding roller group 2 and the finished film guide roller 3 being rotatably mounted on the frame body 1 via bearing seats, the unwinding roller group 2 being used to release the film to be peeled, and the finished film guide roller 3 guiding the peeled film into the subsequent winding process; a peeling frame 4, one end of which is hinged to the frame body 1; a peeling roller 5, rotatably disposed on the peeling frame 4, its axis being parallel to the axis of the finished film guide roller 3, and forming an adjustable peeling angle with the finished film guide roller 3; and an adjustment mechanism 6, mounted on the frame body 1 and drivenly connected to the other end of the peeling frame 4, for driving the peeling frame 4 to swing around its hinge end to adjust the peeling angle. When the adjustment mechanism 6 is working, the peeling frame 4 swings around its hinge end, thereby changing the relative position of the peeling roller 5 and the finished film guide roller 3, realizing flexible adjustment of the peeling angle to adapt to the peeling requirements of different film materials.

[0021] Specifically, the adjusting mechanism 6 is an adjusting cylinder, the cylinder body of which is fixed to the main frame 1 by screws or welding, and the end of the piston rod is connected to the drive end of the peeling frame 4 by a hinge pin. When compressed air is introduced into the adjusting cylinder, the piston rod extends and retracts, causing the peeling frame 4 to rotate around the hinge end, thereby changing the angle between the peeling roller 5 and the finished film guide roller 3. The stroke and thrust of the cylinder can be matched according to the mechanical characteristics of film peeling. For example, for protective films with high adhesion, the peeling angle can be widened by increasing the cylinder thrust, thereby reducing the peeling resistance; while for films with low adhesion, the peeling angle can be reduced to avoid excessive stretching that could damage the film.

[0022] The unwinding roller assembly 2 includes at least one guide roller 7 and two tension rollers 8, which are arranged in parallel side-by-side. The film to be peeled passes sequentially around the guide roller 7 and the tension rollers 8. Preferably, a synchronous drive chain 9 connects the two parallel tension rollers 8 to achieve synchronous rotation of the two tension rollers 8. When one tension roller 8 is driven to rotate, the synchronous drive chain 9 drives the other tension roller 8 to rotate synchronously, ensuring that the film is subjected to balanced force when passing through the tension rollers 8. The pitch and number of sprocket teeth of the synchronous drive chain 9 need to be matched according to the rotational speed and load of the tension rollers 8 to ensure transmission efficiency and stability.

[0023] The outer peripheral wall of the tension roller 8 is provided with a textured structure, which is used to increase the friction between the roller and the film and improve the stability of tension control. Optionally, the textured structure can be a sawtooth pattern, knurling, or mesh-like protrusions. It can be understood that a sawtooth pattern consists of alternating peaks and planes, which is suitable for scenarios that require rapid tension transmission; knurling consists of regularly arranged circular protrusions, which is suitable for the anti-slip requirements of flexible films; mesh-like protrusions consist of intersecting stripes, which can evenly distribute friction and are suitable for tension adjustment of large-area films; different texture forms can be quickly switched by changing the wear-resistant coating or modular roller sleeve on the surface of the tension roller 8.

[0024] In this embodiment, multiple guide rollers 7 are arranged at intervals along the film conveying direction, and the distance between adjacent guide rollers 7 is adjusted according to the width and rigidity of the film. For example, for wide and easily deformable films, the spacing between guide rollers 7 is smaller to provide continuous support; for narrow or high-rigidity films, the spacing can be appropriately increased. The surface of the guide rollers 7 can be covered with an elastic material to reduce frictional resistance, or a fine-tuning mechanism can be provided to adjust the roller position in real time according to the film's running trajectory.

[0025] It also includes a servo motor 10, which is fixedly mounted on the frame body 1, and its output shaft is connected to the finished film guide roller 3 for driving the finished film guide roller 3 to rotate. During the winding stage, the servo motor 10 drives the guide roller to rotate at a constant linear speed to ensure uniform film winding; in the initial stage of peeling, the film tension is gradually released by reducing the rotation speed or briefly reversing the direction of rotation, so as to avoid stress concentration at the moment of peeling that could cause the film to break.

[0026] In this embodiment, the support frame 11 is a welded steel frame, fixed to the bottom of the main frame 1 and in contact with the ground. Adjustable foot pads or shock-absorbing pads are provided at the four corners of the support frame 11 to compensate for uneven ground and absorb vibrations during equipment operation. Under high-speed winding conditions, the rigidity of the support frame 11 can effectively suppress structural deformation caused by resonance, ensuring the operational accuracy and long-term stability of each functional component.

[0027] In summary, the protective film production and winding device of this utility model, by hinged the peeling frame 4 to the main frame 1 and cooperating with the adjustment mechanism 6 driven by the peeling frame 4, can easily drive the peeling frame 4 to swing around the hinge end, thereby realizing flexible adjustment of the peeling angle between the peeling roller 5 and the finished film guide roller 3. Its structural design is reasonable, the adjustment operation is convenient, and the angle control is precise. This design can adapt to the production and winding needs of protective films of different materials and thicknesses, effectively avoiding problems such as tensile damage, wrinkles, and tears caused by improper peeling angles during the winding process, ensuring the integrity and flatness of the protective film during peeling and winding, and significantly improving the production quality of the finished film. At the same time, it enhances the adaptability of the device to different production conditions, broadens the scope of application of the device, and improves the stability and efficiency of the production process, possessing good practicality and versatility. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0028] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
