DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 As shown in Figure 5, the utility model provides a die-cutting machine online printing quality detection device, including a printed product conveying component 1, a printed product detection component 2, a punching and marking component 3, a die-cutting component 4, a mark detection component 5 and a waste kicking component 6.

[0024] Figure 1 and Figure 2As shown, the printed matter conveying assembly 1 includes a first support frame 11 and a conveying plate 12. The conveying plate 12 is mounted on the first support frame 11, and a conveying roller 13 is arranged on the conveying plate 12. The conveying roller 13 is driven by a motor and is used to continuously and stably convey the printed matter to be die-cut. The printed matter detection assembly 2 is installed above or on the side of the conveying plate 12, and is used to detect in real time whether there are printing defects in the printed matter passing by.

[0025] The printed product inspection component 2 uses visual inspection equipment, such as a high-resolution camera and an image processing system. When the printed product passes by, the camera captures the image, and the image processing system analyzes the image to determine whether there are printing defects. Once NG products (unqualified products) are detected, a signal is sent to the control system.

[0026] Figure 2 and Figure 3 As shown, the punch mark assembly 3 is arranged on one side of the printed product detection assembly 2, and the punch mark assembly 3 includes a first mounting frame 31 and a cylinder 32. The first mounting frame 31 is fixed on the frame of the device, and the cylinder 32 is installed up and down on the first mounting frame 31. A punch 33 is installed at the bottom of the cylinder 32. When receiving the NG product signal sent by the printed product detection assembly 2, the cylinder 32 drives the punch 33 to descend and punch and mark the NG product.

[0027] Figure 2 and Figure 4 As shown, the die-cutting assembly 4 is arranged on one side of the punching and marking assembly 3. The die-cutting assembly 4 includes a base plate 41 and a die-cutting machine 42. The die-cutting machine 42 is mounted on the base plate 41 and includes a base 421 and a cutter 422. The base 421 is fixed on the base plate 41, and the cutter 422 is slidably arranged above the base 421. A driving assembly is arranged between the base 421 and the cutter 422, and the driving assembly includes a driving motor 423 and a driving roller 424. The driving motor 423 is mounted on one side of the base 421 and connected to the driving roller 424. A first guide roller 425 is arranged on one side of the outer wall of the driving roller 424, and the two together form a clamping area for stably conveying the printed matter that has been punched and marked. When the printed matter enters the clamping area, the driving motor 423 is started, driving the driving roller 424 to rotate, thereby driving the printed matter to move. At the same time, the cutter 422 moves up and down under the control of the control system to perform die-cutting on the printed matter.

[0028] Figure 1 and Figure 2As shown, the mark detection component 5 is arranged on one side of the die-cutting component 4. The mark detection component 5 includes a second support frame 51, a visual detection component 52 and a light source 53. The second support frame 51 is fixed on the frame of the device, and a first conveyor belt 54 is arranged on it. The visual detection component 52 and the light source 53 are installed on the second support frame 51 and are located above the first conveyor belt 54. The light source 53 provides uniform light, and the visual detection component 52 captures the image of the printed product passing by, and determines whether there is a punch mark through the image processing system, thereby distinguishing NG products from OK products.

[0029] Figure 1 and Figure 5 As shown, the waste kicking assembly 6 includes a second mounting frame 61 and an air knife 62. The second mounting frame 61 is arranged on the second support frame 51, close to the output end of the first conveyor belt 54. The air knife 62 is mounted on the second mounting frame 61. When the mark detection assembly 5 detects NG products, the air knife 62 is started to blow out a high-speed airflow to sweep the NG products into the gap between the first conveyor belt 54 and the second conveyor belt 7. The second conveyor belt 7 is used to convey OK products, thereby realizing the separation of NG products and OK products.

[0030] Through the description of the above embodiments, it can be seen that the die-cutting machine online printing quality detection device of the utility model can detect the quality of printed products in real time during the die-cutting process, and mark and remove NG products, thereby greatly improving production efficiency and product quality.

[0031] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
