Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a printed product defect detection device with an adjustment component. Background Art

[0002] Printed products are a general term for various finished products produced using printing technology. In recent years, with the continuous advancement of detection technology and the increasing abundance of materials, in order to enhance the visual effect or enhance certain surface properties (such as wear resistance, corrosion resistance, etc.), the surface of printed products often needs to be covered with multiple layers of materials. If there is an error in the printing process, resulting in the coverage of the medium on the surface of the printed product not being consistent with the design, it will not only affect the appearance of the printed product, but also affect the corresponding characteristics of the printed product. Therefore, it is necessary to inspect the surface of the printed product to ensure quality. At present, most printed product manufacturers use visual inspection to inspect printed products. This inspection method saves time and effort and is highly efficient. However, the existing visual inspection equipment has a fixed position of the visual camera. This results in the visual camera being too close to the printed product when inspecting larger printed products. The zoom range of the visual camera cannot cover the entire printed product, and thus the complete picture of the printed product cannot be captured, resulting in poor inspection results.

[0003] Therefore, we have made improvements to this and proposed a printed product defect detection device with an adjustment component. Summary of the invention

A pushing assembly 36 is fixedly disposed on the mounting plate C35. The pushing assembly 36 can move the measuring roller 13 of the lifting assembly 8 to the two ends of the printed product I-wheel 3.

[0056] The pushing assembly 36 includes a hydraulic cylinder 37, a roller articulated seat 38 and a rubber roller 39. The hydraulic cylinder 37 is fixedly arranged on the mounting plate C35. The hydraulic cylinder 37 is electrically connected to the roller limit switch 28. The roller articulated seat 38 is articulated with the piston rod of the hydraulic cylinder 37.

The direction of the leveling motor 43 is the same as that of the conveyor belt worktable 1, and the rotation speed of the leveling motor 43 is the same as that of the conveyor belt worktable 1.

[0059] Working principle of the present invention:

[0060] The staff places the printed product I-shaped wheel 3 wrapped with the printed product on the conveying bracket 2, and places one end of the printed product on the bottom of the driven roller 7. The length of the printed product I-shaped wheel 3 corresponds to the width of the matching printed product.

[0061] The hydraulic cylinder 37 of the pushing assembly 36 is started, pushing the roller articulated seat 38 to move toward the two sides of the printed product I-wheel 3. At this time, the rubber roller 39 pushes the shaft connecting rod 12 to move toward the two sides of the printed product I-wheel 3. The outer surface of the measuring roller 13 is attached to the two sides of the printed product I-wheel 3 and the roller limit switch 28 is triggered. The roller limit switch 28 sends a signal, and the hydraulic cylinder 37 stops working.

[0062] When the rubber roller 39 pushes the shaft connecting rod 12 to move toward the two sides of the printing product I-wheel 3, the shaft connecting rod 12 drives the adjustment rod 14 at the other end of the shaft connecting rod 12 to move toward the two sides of the lifting rail frame 9, and the lifting rod 15 drives the lifting frame 10 in the inner cavity of the lifting rail frame 9 to move downward;

[0063] The rollers 26 at the bottom of the lifting rod 15 move toward the two sides of the outer arc surface of the arc plate 22, thereby driving the lifting frame 10 to move downward, that is, the smaller the width of the printed product, the closer the visual inspection camera 11 at the bottom of the lifting frame 10 is to the printed product, and vice versa. Through this operation, the distance between the visual inspection camera 11 and the printed product can be controlled according to the width of the printed product, thereby facilitating the visual inspection camera 11 to detect the complete printed image of the printed product.

[0064] In addition, the hinge groove 29 of the axial connecting rod 12 and the fixing plate 30 can be used to adjust the angle between the axial connecting rod 12 and the adjusting rod 14 , thereby adjusting the lifting height of the lifting frame 10 lifted by the lifting rod 15 .

[0065] Then the conveyor belt workbench 1 is started, and the driven roller 7 elastically squeezes one end of the printed matter between the conveyor belt workbench 1 and the driven roller 7 through the spring rod 6. While the conveyor belt workbench 1 drives the driven roller 7 to rotate, it drives the printed matter I-shaped wheel 3 to rotate through the printed matter, and then the printed matter is transported to the conveyor belt workbench 1. When the front end of the printed matter moves to the leveling roller 42, the leveling motor 43 is started, and the leveling roller 42 squeezes the front end of the printed matter by rotating, so that the printed matter is placed flat on the upper surface of the conveyor belt workbench 1 to prevent the printed matter from warping up. Then the visual detection camera 11 is started to detect the printed matter.
