Description

Technical Field

[0001] This utility model relates to the field of protective film winding technology, specifically a protective film winding device with a fixed-point marking function. Background Technology

[0002] The production process of protective film requires a winding process. The tension of the protective film during winding needs to be adjusted appropriately to ensure that the wound protective film is neatly wound. However, existing protective film winding methods cannot accurately adjust the tension, nor can they dynamically detect and adjust the winding film in real time. This results in the winding film being prone to loosening or wrinkling, and cannot be neatly aligned and tightly wound. Therefore, a device is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a protective film winding device with a fixed-point marking function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective film winding device with a fixed-point marking function, comprising a fixed support base, a fixed-point marking detection body, and an adapter adjustment body. The fixed support base is fixedly installed at the bottom of both ends of the fixed-point marking detection body. The adapter adjustment body is disposed on the outside of the fixed-point marking detection body. The fixed-point marking detection body includes a first support rotating roller, a conveying limiting frame, a nozzle, a solenoid valve, and a conveying hose. The first support rotating roller is rotatably installed on both sides of the bottom of the conveying limiting frame. The solenoid valve is uniformly fixedly installed at the upper part of both ends of the conveying limiting frame. The conveying hose is fixedly connected to the solenoid valve. The nozzle is uniformly fixedly installed inside both ends of the conveying limiting frame, and the solenoid valve is connected to the nozzle.

[0005] Preferably, the adapter adjustment body includes a second support rotating roller, a support base plate, a first electric push rod, and a conveying support plate. The first electric push rod is symmetrically fixedly installed at both ends of the support base plate, the conveying support plate is fixedly connected to the upper end of the first electric push rod, and the second support rotating roller is uniformly rotated and installed on the conveying support plate.

[0006] Preferably, a second electric push rod is symmetrically fixedly installed on the outer end of the supporting base plate, and a first adjustment limit frame and a second adjustment limit frame are respectively fixedly installed between the upper ends of the second electric push rod.

[0007] Preferably, the first and second adjustment limit frames are symmetrically rotated and fitted with limit-positioning adjustment rollers.

[0008] Preferably, the supporting base plate is fixedly connected to the bottom end of the conveying limiting frame.

[0009] Preferably, the second support rotating roller is located between the first support rotating roller and the limiting and adjusting roller.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses a first electric push rod adapted to adjust the height of the second support rotating roller, which in turn controls the height of the first and second adjusting limit frames. This forms three levels of adjustment points that can be operated independently or collaboratively. The second support rotating roller provides initial overall tension adjustment, while the first and second adjusting limit frames can be raised and lowered independently. This allows for differentiated and precise control of the tension at the edges of the protective film, such as correcting deviations and unilateral slack. It effectively solves the problem of loosening or wrinkling during winding, as mentioned in the background art, ensuring that the protective film maintains uniform and moderate tension throughout the entire winding path. To achieve neat and tight winding, the nozzle precisely sprays ink dots to mark the edge of the protective film. After winding, the overlap of the marked points is observed. If the marked points are misaligned, it directly indicates that there are problems such as uneven tension, speed fluctuations, or deviation during the winding process. Multiple sets of electric push rods drive rollers and limit frames at different positions to achieve fast, accurate, and multi-dimensional dynamic tension adjustment. Ultimately, this effectively solves the problems of looseness, wrinkles, and unevenness caused by inaccurate tension control during the protective film winding process, significantly improving winding quality and efficiency. Its structural design takes into account both functional implementation and smooth operation, and the modular design also enhances practicality. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides an embodiment of a protective film winding device with a fixed-point marking function, comprising a fixed support base 1, a fixed-point marking detection body 2, and an adapter adjustment body 3. The fixed support base 1 is fixedly installed at the bottom of both ends of the fixed-point marking detection body 2, and the adapter adjustment body 3 is disposed on the outside of the fixed-point marking detection body 2. The fixed-point marking detection body 2 includes a first support rotating roller 4, a conveying limit frame 5, a nozzle 6, a solenoid valve 7, and a conveying hose 8. The first support rotating roller 4 is rotatably installed on both sides of the bottom of the conveying limit frame 5. The solenoid valve 7 is evenly fixedly installed at the upper part of both ends of the conveying limit frame 5. The conveying hose 8 is fixedly connected to the solenoid valve 7. The nozzle 6 is evenly fixedly installed inside both ends of the conveying limit frame 5, and the solenoid valve 7 is connected to the nozzle 6. The conveying hose 8 is connected to an external inkjet device. During the required detection process, the fixed-point marking and detection ink dots can be sprayed out through the nozzle 6 at the designated position, which is convenient for observation and judgment.

[0018] The adapter adjustment body 3 includes a second support rotating roller 9, a support base plate 10, a first electric push rod 11, and a conveying support plate 12. The first electric push rod 11 is symmetrically fixed at both ends of the support base plate 10, and the conveying support plate 12 is fixedly connected to the upper end of the first electric push rod 11. The second support rotating roller 9 is uniformly rotated and installed on the conveying support plate 12.

[0019] A second electric push rod 13 is symmetrically fixedly installed on the outer end of the support base plate 10. A first adjustment limit frame 14 and a second adjustment limit frame 16 are respectively fixedly installed between the upper ends of the second electric push rod 13, which can realize precise and sufficient limit and tension adjustment.

[0020] The first adjusting limit frame 14 and the second adjusting limit frame 16 are symmetrically rotated inside to install the limiting roller 15, which can make the protective film conveyed inside the first adjusting limit frame 14 and the second adjusting limit frame 16 be conveyed smoothly.

[0021] The support base plate 10 is fixedly connected to the bottom end of the conveying limit frame 5.

[0022] The second support rotating roller 9 is located between the first support rotating roller 4 and the limit and baffle adjusting roller 15, which can achieve continuous support and make the conveying smooth.

[0023] Working principle: During the uniform speed conveying and winding process of the protective film, the protective film passes through the inside of the conveying limit frame 5 at a uniform speed and is supported by the first support rotating roller 4 set inside the bottom of the conveying limit frame 5. According to the different widths of the protective film, ink dots are evenly sprayed onto the edge of the protective film through the pre-set nozzles 6. After the uniformly conveyed protective film is wound up, it is observed whether the uniformly and continuously conveyed ink dots can overlap. If they overlap and align, it means that the protective film is conveyed with uniform speed and tension during the winding process. If they cannot align, it means that the protective film cannot be wound up at a uniform speed or with proper tension during the conveying process. At this time, the first electric push rod 11 is activated to raise the conveying support plate 12, and the second support rotating roller 9 initially achieves the conveying limit. The protective film inside frame 5 is initially supported and tensioned. Then, the corresponding second electric push rod 13 is activated to control the second adjusting limit frame 16 and the first adjusting limit frame 14 to rise and fall respectively. This allows the protective film to be accurately and fully tensioned after being conveyed from inside the second adjusting limit frame 16 and the first adjusting limit frame 14. Furthermore, the limiting and adjusting rollers 15 set inside the second adjusting limit frame 16 and the first adjusting limit frame 14 can ensure smooth conveying of the protective film conveyed from inside the first adjusting limit frame 14 and the second adjusting limit frame 16. Therefore, this device can accurately and evenly tension the protective film for conveying, allowing the protective film to be neatly rolled up without wrinkles due to loose or uneven winding.
