Description

Technical Field

[0001] This utility model relates to the field of film processing equipment, and in particular to a film receiving device with composite function. Background Technology

[0002] In the processing of thin film materials, a protective film is usually applied to the film to protect the underlying material. However, during material processing, the protective film is easily scratched, which affects the appearance and surface quality of the final product. To meet the requirements for product appearance and surface scratches, the protective film needs to be replaced. Current technology, if replacement is required, involves first winding the main film, then transferring it to a separate laminating machine for secondary unwinding, lamination, and winding. This method has the following drawbacks: it requires a second unwinding / winding, resulting in a lengthy process and low efficiency; and the film is prone to secondary contamination or scratches during transport. Meanwhile, during the conveying and lamination of film materials, problems such as material misalignment and unstable tension can easily occur due to factors such as inertia, affecting processing accuracy and quality. Therefore, there is an urgent need for a film receiving device with a short conveyor line, high integration, and precise lamination to apply new covering material onto the film. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a film collecting device with composite functions.

[0004] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution: A composite film receiving device includes a film conveying mechanism, an old protective film receiving mechanism, a feeding mechanism, a laminating mechanism, and a film receiving unit. The film conveying mechanism includes conveying rollers for conveying film material along the film conveying direction; the old protective film receiving mechanism is used to wind up the old protective film; the feeding mechanism is used to store and output new flexible covering material, and also includes several guide rollers for guiding the new flexible covering material so that the film conveying path and the path of the new flexible covering material passing through the guide rollers converge at the laminating mechanism; the laminating mechanism includes a mechanism for bonding the film material with the new flexible covering material. The pressing rollers, with the upper and lower rollers forming a channel for bonding the film and the new flexible covering material, are used to roll up the finished film with the new flexible covering material bonded by the bonding mechanism. The unloading mechanism, the old protective film loading mechanism, and the film loading mechanism each have a central rotating shaft for winding or unwinding. At least the central rotating shafts of the film loading mechanism and the old protective film loading mechanism are connected to a rotational power source to drive their rotation. The old protective film loading mechanism and the unloading mechanism are located on the same side above or below the bonding mechanism, with the unloading mechanism located downstream of the old protective film loading mechanism in the film conveying direction. Typically, the new flexible covering material can be a new protective film or adhesive tape. Integrating the old protective film recycling, new material unwinding, lamination, and finished product winding into the same conveying path, with the old protective film loading mechanism and the unloading mechanism located on the same side of the bonding mechanism and arranged upstream and downstream, creates a compact space. The new flexible covering material is immediately bonded after the old protective film is recycled, reducing the amount of material being transported in an exposed state.

[0005] Preferably, a correction mechanism is also included. This mechanism comprises a sensing device for detecting whether the material is misaligned and an adjusting drive device. The sensing device and the adjusting drive device are connected via a control device. The sensing device is located on the conveying path between the two guide rollers of the new flexible cover material. The correction mechanism can detect the positional deviation of the new flexible cover material in real time and adjust it in a closed-loop manner through the control device, ensuring the alignment accuracy between the applied material and the underlying film or multilayer composite material, thus reducing waste.

[0006] Preferably, the sensing device is any one of an ultrasonic correction sensor, an infrared sensor, or a vision sensor, and the adjustment drive device is used to adjust the position of the roller according to the sensing result.

[0007] Preferably, the central rotating shaft of the feeding mechanism is mounted on a sliding seat via a bearing. The sliding seat is slidably mounted on a slide rail, with the slide rail extending in the axial direction of the central rotating shaft. The output end of the adjusting drive device is connected to the sliding seat to adjust the axial position of the material roll of the feeding mechanism.

[0008] Preferably, the adjustment drive device is an electric cylinder or motor whose output end is fixedly connected to the sliding seat. It has a fast response to controller commands and high repeatability.

[0009] Preferably, each central shaft is connected to a brake device for controlling the material conveying tension during receiving or discharging. The brake device stops the rotation of the central shaft when activated. This ensures stable tension during the conveying of the film, old protective film, and new flexible covering material. When the machine is stopped, it prevents the film from continuously pulling due to inertia, which could lead to excessive and uneven material residue or instantaneous breakage.

[0010] Preferably, the braking device is a magnetic powder clutch. The magnetic powder clutch has a transmission mechanism that allows the central rotating shaft to disengage from the rotating power source while the rotating power source is in operation, and the central rotating shaft can stop rotating immediately.

[0011] Preferably, the laminating mechanism includes at least one conveying platform with suction holes connected to a negative pressure source to generate suction on the film. The conveying platform is located upstream of the pressure roller. The main film undergoes vacuum adsorption to eliminate wrinkles in the material.

[0012] Preferably, a pressure bar for pressing the film is provided above the conveyor platform.

[0013] This utility model, by adopting the above technical solution, has significant technical effects: Peeling, lamination, and winding are all completed on the same machine. The old protective film is rolled up in real time, keeping the site clean and greatly improving efficiency. It occupies little space. After the old protective film is recycled, it is immediately pressed with new flexible covering material, reducing the need for conveying the roll in an exposed state.

[0014] The braking device enables full tension control, resulting in wrinkle-free and stretch-free finished products. The position of the feeding mechanism is adjusted in real time through correction to ensure the alignment accuracy between the applied material and the underlying film or multi-layer composite material, thereby reducing waste.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] Example 1 Film collecting devices with composite functions, such as Figure 1-4 As shown, the system includes a film conveying mechanism, an old protective film receiving mechanism 1, a feeding mechanism 3, a laminating mechanism 4, and a film receiving mechanism 5. The film conveying mechanism includes a conveying roller 2 for conveying the film material along the film conveying direction; the old protective film receiving mechanism 1 is used to wind up the old protective film; the feeding mechanism 3 is used to store and output new flexible covering material, and also includes several guide rollers 31 for guiding the new flexible covering material, so that the path of the film conveying path and the path of the new flexible covering material passing through the guide rollers 31 converge at the laminating mechanism 4; the laminating mechanism 4 includes a pressure roller 41 for pressing the film material and the new flexible covering material together. A channel for bonding the film and the new flexible covering material is formed between the upper and lower pressure rollers 41; the film take-up mechanism 5 is used to wind up the finished film with the new flexible covering material bonded by the bonding mechanism 4; wherein, the unloading mechanism 3, the old protective film take-up mechanism 1, and the film take-up mechanism 5 are each provided with a central rotating shaft 6 for winding or unwinding, and at least the film take-up mechanism 5 and the old protective film take-up mechanism 1 are connected to a rotational power source 61 to drive their rotation, the old protective film take-up mechanism 1 and the unloading mechanism 3 are both located on the same side above or below the bonding mechanism 4, and the unloading mechanism 3 is located downstream of the film conveying direction of the old protective film take-up mechanism 1.

[0019] It also includes a correction mechanism 7, which includes a sensing device 71 for sensing whether the material is misaligned and an adjustment drive device 72. The sensing device 71 and the adjustment drive device 72 are connected by a control device 73. The sensing device 71 is located on the conveying path between the two guide rollers 31 of the new flexible covering material.

[0020] The sensing device 71 can be any one of an ultrasonic correction sensor, an infrared sensor, or a vision sensor, and the adjustment drive device is used to adjust the position of the roller according to the sensing result.

[0021] The central rotating shaft 6 of the feeding mechanism 3 is mounted on the sliding seat 32 via bearings. The sliding seat 32 is slidably mounted on the slide rail 33. The extension direction of the slide rail 33 is the axial direction of the central rotating shaft 6. The output end of the adjusting drive device 72 is connected to the sliding seat 32 to adjust the axial position of the material roll of the feeding mechanism 3.

[0022] The adjustment drive device 72 is an electric cylinder or motor whose output end is fixedly connected to the sliding seat 32.

[0023] Each central rotating shaft 6 is connected to a brake device 62 for controlling the material conveying tension during material receiving or discharging. The brake device 62 stops the rotation of the central rotating shaft 6 when activated.

[0024] The braking device 62 is a magnetic powder clutch.

[0025] The bonding mechanism 4 includes at least one conveying platform 42, on which suction holes 43 are provided. The suction holes 43 are connected to a negative pressure source 44 to generate suction force on the film on the conveying platform 42. The conveying platform 42 is located upstream of the pressure roller 41.

[0026] A pressing strip 45 for pressing the film is provided above the conveying platform 42.

[0027] Working principle: After processing, the old protective film with scratches is wound up by the winding mechanism. The central shaft 6 of the old protective film winding mechanism 1 is driven by a power source 61, and the brake device 62 stops the central shaft 6 when the power source stops, preventing the old protective film from continuing to be wound up due to inertia. At the same time, the unwinding mechanism 3 unwinds the new flexible covering material. The central shaft 6 of the unwinding mechanism 3 is also driven by the power source 61 and is equipped with a brake device 62. When the power source 61 stops, the brake device 62 stops the central shaft 6 in time, preventing excessive material feeding due to inertia.

[0028] As the unwinding mechanism 3 unwinds the new flexible cover material near the output point, the sensing device 71 of the correction mechanism continuously senses whether the material is misaligned. If misalignment is detected, the adjustment drive device adjusts the axial position of the central shaft 6 of the unwinding mechanism 3 according to the sensing result to ensure that the edges of the material are aligned.

[0029] During the conveying process, the new flexible covering material of the feeding mechanism 3 is wrapped around the guide roller 31, keeping the material in a taut state, reducing material vibration and improving flatness. The film material that takes away the old protective film is suctioned by the negative pressure of the conveying platform 42, ensuring the flatness of the feed. Then, it passes between the two pressure rollers 41 with the new flexible covering material to achieve the bonding of the two, ensuring that the new flexible covering material is firmly bonded to the film material. The central rotating shaft 6 of the film taking mechanism 5 is driven by the rotating power source 61 to wind up the film.
