Technical Field

[0001] The utility model relates to the technical field of high-speed rewinding and product inspection machines, in particular to a detection mechanism used in high-speed rewinding and product inspection machines. Background Art

[0002] During the printing process, due to various factors, printed materials often exhibit color differences, misregistering, missing colors, or staining, resulting in defective products. Inspection machines are suitable for inspecting web materials (film, paper, and aluminum foil) after printing and coating. They can also be used to rewind materials, ensuring that the ends of the webs are neat and properly tight. They are essential equipment for the printing industry, especially the flexible packaging printing industry. Currently, printed material quality inspections are typically performed manually on inspection machines. However, due to the high-speed motion of the objects being observed, accurate observation and inspection by the human eye is difficult, making errors more likely. Summary of the Invention

[0003] In response to the shortcomings of the above-mentioned existing technologies, a detection mechanism of a high-speed rewinding and inspection machine is provided, which makes it convenient for staff to inspect the high-speed running packaging film after printing, and to promptly discover printing defects in the packaging film, thereby facilitating the observation of the fast-moving packaging film and avoiding the occurrence of unqualified batch production during the printing production of the packaging film.

[0011] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] like Figure 1-3 As shown, the inspection mechanism of the high-speed rewinding inspection machine includes a high-speed rewinding inspection machine body 1, a first bracket mounted on the high-speed rewinding inspection machine body 1, and a second bracket corresponding to the first bracket. The first bracket is equipped with a photoelectric inspection head 2, and the second bracket is equipped with a strobe light 3. The controller also includes a PLC. The photoelectric inspection head collects speed frequency and sends a signal to the PLC, which then sends a signal to the strobe light to control the strobe light frequency and inspect the overprint quality.

[0013] The photoelectric detection head uses the principle of photoelectric conversion to convert the speed of mechanical motion into an electrical signal whose frequency is proportional to the speed of the mechanical motion. When this signal is transmitted to a PLC (programmable logic controller), the PLC controls the flashing frequency of the strobe light based on the received signal frequency. Specifically, the PLC analyzes the frequency of the signal sent by the photoelectric detection head to calculate the speed of the mechanical motion. It then adjusts the flashing frequency of the strobe light based on this speed information, ensuring that the flashing speed of the strobe light remains consistent with the speed of the mechanical motion or in a certain proportional relationship. By precisely controlling the flashing frequency of the strobe light, the high-speed packaging film appears to be stationary. This allows for inspection of the printed packaging film without stopping the equipment, allowing for timely detection of any printing defects. This facilitates the observation of the fast-moving packaging film and prevents batch defects during the printing process.

[0014] The first bracket includes two vertically arranged longitudinal bars 4 and a cross bar 5 arranged between the two longitudinal bars 4. The cross bar 5 is provided with a first adjustable supporting frame slidably connected to the cross bar 5 for supporting the strobe light 3.

[0015] The first adjustable supporting frame includes a first supporting block 6 and a first sliding cavity 7 opened on the first supporting block 6. The first supporting block 6 is provided with a first positioning bolt 8 for fixing the first supporting block 6 on the cross bar 5 when the first supporting block 6 slides to a predetermined position on the cross bar 5.

[0016] The second bracket includes two corresponding longitudinal plates 9 and a transverse plate 10 disposed between the two longitudinal plates 9 . The transverse plate 10 is provided with a second adjustable supporting frame slidably connected to the transverse plate 10 for supporting the strobe light 3 .

[0017] The second adjustable bearing frame includes a second bearing block 14, an inclined bearing surface is provided on the second bearing block 14, a bearing plate 12 is provided on the inclined bearing surface, a second sliding cavity 13 is opened on the second bearing block 14, and a second positioning bolt 11 is provided on the second bearing block 14 for fixing the second bearing block 14 on the horizontal plate 10 when the second bearing block 14 slides to a predetermined position on the horizontal plate 10.

[0018] By providing the first adjustable carrier and the second adjustable carrier, the photoelectric detection head can be adjusted left and right to find a suitable photoelectric position to adapt to the observation of different types of packaging films.

[0019] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
