[0020] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a maintainable printing quality inspection device includes a frame 1, wherein the lower part of the frame 1 is bolted to a base 2, a motor 5 is installed on the upper left front side of the base 2, transmission rollers 3 are respectively connected to bearings on the left and right sides of the interior of the frame 1, a transmission belt 4 is installed between the two transmission rollers 3, wherein the front end of the transmission roller 3 on the left side extends to the front part of the frame 1, and the front end of the transmission roller 3 on the left side is connected to the output shaft coupling of the motor 5, a bracket 6 is bolted to the left side of the upper middle part of the frame 1, and an inspection camera 7 is bolted to the lower part of the horizontal section of the bracket 6.

[0021] One of the maintainable printing quality inspection devices further includes an electric driving guide plate structure 8 and a height-adjusting adhesion roller structure 9 , wherein the electric driving guide plate structure 8 is connected to the base 2 , and the height-adjusting adhesion roller structure 9 is connected to the frame 1 .

[0022] The electric pushing guide plate structure 8 comprises a guide plate 81, and a placement plate 82 is integrally provided at the lower right end of the guide plate 81. When unqualified printed products are pushed forward, they fall to the placement plate 82 through the guide plate 81. An anti-skid layer 83 is glued to the upper part of the placement plate 82. Side baffles 84 are glued to the front and rear sides between the inclined section of the guide plate 81 and the placement plate 82, respectively. The anti-skid layer 83 hinders the falling printed products, so that the printed products stay on the placement plate 82, which is convenient for inspectors to remove the printed products from the placement plate 82, thereby picking out unqualified printed products. An electric pushing plate structure 85 is installed on the upper part of the horizontal section of the guide plate 81.

[0023] In this embodiment, combined with the Figure 3As shown, the electric push plate structure 85 includes an electric push rod 851, and the left and right sides of the lower part of the electric push rod 851 are respectively bolted with a pad 852. When the inspector finds unqualified printed products, the output rod of the electric push rod 851 is controlled by an external electric push rod controller. The right end of the output rod of the electric push rod 851 is bolted with a push plate 853. The output rod of the electric push rod 851 pushes the push plate 853, thereby pushing the unqualified printed products on the upper part of the transmission belt 4 forward.

[0024] In this embodiment, combined with the Figure 4 As shown, the height-adjustable adhesion roller structure 9 comprises an inverted U-shaped frame 91 and a fixed shaft 92. The fixed shaft 92 passes through a through slot 93 provided at the front and rear sides of the inverted U-shaped frame 91, and the front and rear ends of the fixed shaft 92 are respectively connected to the inverted U-shaped frame 91 through fixing nuts 94. By loosening the fixing nuts 94, the height of the fixed shaft 92 and the adhesion roller 95 can be adjusted. The outer end of the fixed shaft 92 is sleeved with an adhesion roller 95. When a flat-plate printed matter such as a PMMA plate passes over the upper part of the transmission belt 4, the adhesion roller 95 contacts with the surface of the printed matter and adheres to impurities such as dust on the surface of the printed matter, thereby improving the accuracy of printed matter inspection. The adhesion roller 95 is arranged inside the inverted U-shaped frame 91.

[0025] In this embodiment, specifically, the horizontal section of the guide plate 81 is disposed between the lower portion of the upper horizontal section of the transmission belt 4 and the upper portion of the frame 1 .

[0026] In this embodiment, specifically, the placement plate 82 is bolted to the upper right front side of the base 2 .

[0027] In this embodiment, specifically, the two pads 852 are bolted side by side from left to right on the upper left side of the horizontal section of the guide plate 81 .

[0028] In this embodiment, specifically, the inverted U-shaped frame 91 is bolted to the upper left side of the frame 1 .

[0029] In this embodiment, specifically, the motor 5 adopts a 5IK60GN series motor; the electric push rod 851 adopts an XTL series electric push rod.

[0030] In this embodiment, specifically, the guide plate 81 is made of a V-shaped stainless steel plate; the placement plate 82 is made of a stainless steel plate; the anti-slip layer 83 is made of a rubber layer; and the push plate 853 is made of a PVC plastic plate.

[0031] In this embodiment, specifically, the adhesion roller 95 is a PVC plastic cylinder with a felt layer glued to the outside.

[0032] How it works

[0033] In the present invention, the motor 5 is connected to an external power source, and the printed matter is placed on the upper part of the transmission belt 4. The motor 5 drives the transmission belt 4 to rotate through the transmission roller 3 to realize the function of conveying the printed matter, saving manpower for manually picking up and inspecting the printed matter. The inspection camera 7 is connected to an external computer device, and the inspector can conveniently inspect the quality of the printed matter by observing the display screen of the computer device. When a flat-plate printed matter such as a PMMA plate passes through the upper part of the transmission belt 4, the adhesion roller 95 contacts the surface of the printed matter and adheres impurities such as dust on the surface of the printed matter, thereby improving the accuracy of the printed matter inspection. When the inspector finds unqualified printed matter, the output rod of the electric push rod 851 is controlled by an external electric push rod controller, so that the push plate 853 pushes the unqualified printed matter on the upper part of the transmission belt 4 forward, and the unqualified printed matter falls to the placement plate 82 through the guide plate 81. The anti-skid layer 83 has an obstructive effect on the falling printed matter, so that the printed matter stays on the placement plate 82, which is convenient for the inspector to remove the printed matter from the placement plate 82, thereby picking out the unqualified printed matter.

[0034] Utilizing the technical solution described in the present invention, or those skilled in the art designing a similar technical solution inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
