In addition, the existing structure is relatively cumbersome and has high manufacturing costs.

[0018] When the internal structure of the device is being processed, the telescopic cylinder 31 at the bottom will pre-drive the support frame 33 to rise or fall in height, thereby ensuring the normal use and processing of the structure and providing stable support for the internal structure.

[0020] When cleaning both ends of the protective film, firstly, the second cleaning component 53 at the bottom is driven by the lifting active component 3. During structural driving, the active transmission component 55 at the side of the limit frame 54 engages with the driven transmission component 52 at the top.

[0023] When the lifting active component 3 is in the lifting drive, the clamping parts 63 at both ends will slide along the inner wall of the sliding part 61 and, under the elastic support of the elastic buffer component 8, will press the protective film on the top to reduce the impact of insufficient tension of the protective film on subsequent detection.

[0024] The elastic clamping component 6 includes, but is not limited to, a pressure plate tensioning structure and a roller tensioning structure; in this embodiment, the elastic clamping component 6 preferably has a roller tensioning structure.

[0027] The auxiliary processing component 7 includes, but is not limited to, a manual auxiliary structure and an electric auxiliary structure; in this embodiment, the auxiliary processing component 7 is preferably an electric auxiliary structure.

[0028] The elastic buffer assembly 8 includes a lifting block 81 and a mounting plate 82. A guide rod 83 is installed on the inner wall of the mounting plate 82.

Then, the elastic part 87 at the side end will provide elastic support for the sliding parts 84 to ensure that the elastic pressing component 6 is attached to the inner wall of the protective film.

[0030] Among them, the elastic buffer component 8 includes, but is not limited to, rubber buffer pad type and spring buffer type; in this embodiment, the elastic buffer component 8 is preferably spring buffer type.

[0031] The working principle of the online defect detection and marking device for PE protective film provided by this utility model is as follows: When the device performs inspection and marking on the protective film, it first places and winds the protective film through the auxiliary processing components 7 at both ends. During the drive winding, the inspection and marking workpiece 2 in the middle automatically inspects the protective film. During the drive winding, the bottom lifting active component 3 lifts the transmission cleaning components 5 at both ends and engages with the top active cleaning component 4 to clean the inner walls of both ends of the protective film, reducing impurities on the surface of the protective film that could affect subsequent inspection processes. When the lifting active component 3 lifts the protective film, the elastic pressing components 6 at both ends are driven by the lifting active component 3 and elastically supported by the elastic buffer component 8 to perform synchronous pressing of the protective film, reducing the phenomenon of the protective film loosening during inspection.

[0032] Compared with related technologies, the online defect detection and marking device for PE protective film provided by this utility model has the following beneficial effects: To improve ease of use, the device employs an active cleaning component 4 and a transmission cleaning component 5 in conjunction with the lifting active component 3. This allows for structural meshing and transmission, cleaning the inner walls of both ends of the protective film. This reduces the impact of impurities on the film surface on subsequent testing results. Furthermore, cleaning can be performed without an external drive source. During the lifting and lowering process, the active lifting component 3, through the cooperation of the elastic pressing component 6 and the elastic buffer component 8, simultaneously provides elastic compensation and pressing to the protective film, ensuring stable tension and preventing loosening and folding during testing.
