A connecting frame 644 is fixedly mounted on the inner side of the concave frame 641. A positioning roller 645 is rotatably connected to the inner side of the connecting frame 644. The main function of the positioning assembly 64 is to accurately position and fix the printed film to ensure that the printed film can maintain a stable state during the detection process. The positioning assembly 64 is mainly composed of the concave frame 641. The concave frame 641 is fixedly mounted on the upper end of the support frame 63, providing a solid foundation for the entire positioning assembly 64. The design of the concave frame 641 not only takes into account the load-bearing capacity, but also fully considers the convenience of operation, which is convenient for users to install and adjust. The second electric push rod 642 is fixedly mounted on the outer middle part of the concave frame 641, and its output end passes through the concave frame 641 and is connected to the limiting arc plate 643. When the second electric push rod 642 is started, it can push the limiting arc plate 643 to move up and down, thereby realizing For the positioning of the printed film in the vertical direction, this design enables the positioning component 64 to flexibly adapt to printed films of different thicknesses, thereby improving the accuracy and stability of positioning. The design of the limiting arc plate 643 fully considers the morphological characteristics of the printed film, and the arc structure can better fit the surface of the printed film, ensuring that the printed film will not be damaged during the positioning process.

The positioning component 64 realizes the precise positioning and fixation of the printed film through the coordinated action of the concave frame 641, the second electric push rod 642, the limiting arc plate 643 and the positioning roller 645.

[0040] Please refer to Figure 7-Figure 8A support frame 65 is fixedly installed at the bottom of the second electric push rod 642. The support frame 65 is T-shaped when viewed from above. The outer ends of the bottom of the support frame 65 are rotatably connected with balls 66. The bottom of the balls 66 is fitted and connected to the top of the top plate 5.

These convex strips are made of rubber material and have good elasticity and wear resistance. The setting of the rubber convex strips not only increases the contact area between the limiting arc plate 643 and the printing film, but also effectively distributes the friction force to a wider area, thereby fixing the printing film more firmly. Similarly, the outer surface of the positioning roller 645 is also fixedly connected with anti-skid convex strips at equal intervals. 646, these convex strips are also made of rubber material, which can generate sufficient friction when in contact with the printed film to prevent the printed film from sliding on the roller.

[0042] The implementation principle of a printed film tensile strength detection device according to an embodiment of the present application is as follows: by setting up an adjustment mechanism 3, the function of the printed film tensile strength detection device is further optimized and enhanced. This design enables the device to more efficiently and accurately complete the tensile strength detection of the printed film when in use. Specifically, the introduction of the adjustment mechanism 3 makes the positioning and detection process of the printed film more convenient and automated. By arranging the two ends of the printed film on the positioning rollers 645 on the inner sides of the concave frame 641 and the connecting frame 644, and starting the second electric push rod 642 to run, the device can automatically fit the limiting arc plate 643 and the outer surface of the positioning roller 645, thereby achieving stable positioning of the printed film. This positioning method is not only fast, but also can significantly improve the stability and accuracy of positioning through the design of the anti-slip convex strip 646. After the positioning is completed, by starting the second motor 32 to run, the slider 34 is driven by the rotation of the screw rod 33. The support plates 61 can slide back and forth horizontally and vertically inside the slide groove 31. This design enables the support plates 61 to move relative to each other, thereby conveniently adjusting the position of the tension sensor 62. When the support plates 61 move toward the outside, the tension sensor 62 will also be pulled outward accordingly. At this time, the printed film can be stretched. During this process, the tension generated by the printed film will be monitored and recorded in real time by the tension sensor 62, thereby accurately evaluating its tensile strength. In addition, the design of the positioning mechanism 6 and the positioning component 64 further simplifies the operating steps and improves the overall detection efficiency. By quickly positioning the printed film, the device can complete the tensile strength detection of the entire printed film in a short time, greatly saving detection time and labor costs. By setting the adjustment mechanism 3, the printed film tensile strength detection device realizes a fast, automatic and accurate detection function, and is easy to operate and efficient, which can significantly improve the quality control level in the production process of the printed film.

[0043] First, the printed film is positioned on the device to ensure that it remains stable during the detection process. Then, by starting the first electric push rod 72, the base plate 73 is pushed upward. The upward movement of the base plate 73 drives the slide plates 74 at both ends to slide upward. The movement of the slide plates 74 further prompts the tripod 93 to move upward. The upward displacement of the tripod 93 causes the arc-shaped pressure rod 95 to apply pressure to the printed film. This pressure application method can simulate the state of the printed film being uniformly compressed in actual use, so as to detect its tensile resistance in this state. When it is necessary to adjust the pressure application method, the first motor 92 can be started to drive the tripod 93 to rotate. The rotation of the tripod 93 will drive the blade-shaped pressure rod 94 to move to the uppermost end. Subsequently, the first electric push rod 72 is moved again. The device can simulate the situation when a sharp object contacts and presses the printed film. This simulation can more realistically reflect the tensile strength of the printed film when it is scratched or pressed by a sharp object. In addition, the device also has the function of simulating the tensile strength of the printed film under different temperature conditions. By starting the first motor 92 and adjusting the tripod 93 to rotate again, the reflector 961 can be directed upward. At this time, the electric heating lamp 963 inside the reflector 961 is started to operate. The electric heating lamp 963 cooperates with the reflector 961 to perform concentrated heating, so as to increase the temperature of the pressing shaft 962. At the same time, the temperature on the pressing shaft 962 is detected in real time by the temperature sensor 964. When the pressing shaft 962 reaches the set temperature, the pressing shaft 962 is pushed upward to contact the printed film by the first electric push rod 72. In this way, It can simulate the tensile strength of the printed film under different temperature conditions, so as to comprehensively evaluate its performance. During the whole detection process, the device realizes high-precision detection of the tensile strength of the printed film by accurately controlling the operation of the pressure-applying mechanism 7 and simulating different conditions. At the same time, it has strong adaptability and can simulate and detect the tensile strength of the printed film under different conditions, which provides strong support for the quality control of the printed film. The printed film tensile strength detection device realizes comprehensive simulation and detection of the tensile strength of the printed film under different conditions through the ingenious design of the pressure-applying mechanism 7 and the precise control system. Its use principle is simple and clear, and its operation is convenient and efficient, which provides important technical support for the quality control of printed films and the development of related industries. The pressure-applying mechanism 7 can accurately The device can accurately simulate different forms of pressure applied to the printed film, including uniform pressure, sharp object contact pressure and pressure under different temperature conditions. This high-precision simulation enables the device to accurately evaluate the tensile strength of the printed film under various actual use conditions. The device can easily adjust the pressure mode and pressure size through the cooperation of the first electric push rod 72 and the first motor 92. Whether it is uniform pressure or simulation of sharp object contact, or testing at different temperatures, it can be achieved through simple operations, which greatly enhances the versatility of the device. The rapid response and precise control of the pressure mechanism 7 make the entire detection process more efficient. The operator can quickly set the required test conditions and obtain the test results in a short time, thereby improving production efficiency.The device is designed with full consideration of safety factors. The pressure mechanism 7 has stable performance during operation, which can avoid accidental injuries to operators. At the same time, the device is also equipped with necessary safety protection devices to ensure the safety and reliability of the test process. The operation of the pressure mechanism 7 is simple and intuitive.
