Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1, as Figs. 1-4 As shown, this embodiment aims to solve the technical problems existing in the quality inspection of appearance defects of printed materials such as books after printing. To this end, the rapid inspection mechanism for finished printed materials provided in this embodiment includes a frame 1 and a conveyor belt rotatably mounted on the frame 1. A visual inspection box 2 is also provided on the frame 1 and is located above the conveyor belt. The above structure is a common existing mechanism, so it will not be described in detail in this embodiment. Unlike the existing ones, the existing visual inspection box 2 only has one set of inspection equipment. In this embodiment, a set of inspection equipment is provided at both the front and rear ends of the visual inspection box 2, mainly used to complete the inspection of the front and back sides.

[0018] In view of the main problem in the prior art that printed matter is difficult to detect, the printed matter of the book type is attached to the conveying belt. If one side of the book spine is lifted, the book can be turned over, but page compression may occur, causing defects. If one side of the book page is lifted, it is difficult to lift, and the book page may be damaged when it is pried up. Therefore, it is most appropriate to lift the book page from the bottom of the conveying belt, and the printed matter of the book type is attached to the conveying belt. To solve this problem, in the embodiment, the conveying belt is provided with a first conveying belt 11 and a second conveying belt 12 along the moving direction of the printed matter. The first conveying belt 11 and the second conveying belt 12 are arranged adjacent to each other. Adjacent arrangement means that the distance between the first conveying belt 11 and the second conveying belt 12 is minimized under the condition of no friction. The purpose of this arrangement is mainly that too large a distance will prevent the book from being transported. The arrangement of the two conveying belts mainly utilizes the semicircular end of the conveying belt. In this way, a groove is formed between the two conveying belts, and the book page can be lifted from the bottom of the groove.

[0019] To ensure that the printed matter such as books can be lifted at the specified position, in the embodiment, a limiting plate 111 is further arranged on the first conveying belt 11. The limiting plate 111 is adjustably fixed on the conveying belt by the fixed columns on both sides of the conveying belt. In this way, due to the limitation of the limiting plate 111, the printed matter is conveyed by the middle of the first conveying belt 11.

[0020] After the moving route of the printed matter is determined, the printed matter needs to be turned over after the front surface detection is completed. Therefore, a printed matter turning guide mechanism 3 is further arranged on the conveying belt. The printed matter turning guide mechanism 3 includes a left guide plate 31 and a right guide plate 32. The left guide plate 31 and the right guide plate 32 are integrally arranged in a plate shape, but their shapes are processed by sheet metal. The left guide plate 31 and the right guide plate 32 are arranged at intervals. The distance between the left guide plate 31 and the right guide plate 32 forms a channel through which the printed matter passes.

[0021] To turn over the book when the printed matter passes through the left guide plate 31 and the right guide plate 32, in the embodiment, the left guide plate 31 is sequentially provided with an inclined part 311, a vertical part 312, and a guide part 313 from the first conveying belt 11 to the second conveying belt 12. It should be noted that the left guide plate 31 is vertically arranged. More specifically, the inclined part 311 and the vertical part 312 are vertically arranged. The inclined part 311 is inclinedly arranged from the side edge of the conveying belt to the middle. In this way, after the printed matter passes through the inclined part 311, it moves from the middle to the right side. When the printed matter reaches the vertical part 312, it is already in a vertical state. Since it needs to be turned over, the guide part 313 is twisted from the vertical state of the vertical part 312 to an inclined state or a horizontal state. The twisting direction is left, so that the printed matter tilts to the left.

[0022] In order to cooperate with the use of the left guide plate 31, in the embodiment, the right guide plate 32 is sequentially provided with a lifting corner part 321, a twisting part 322, a vertical part 323 and a turning part 324 from the first conveying belt 11 to the second conveying belt 12, wherein the cross section of the lifting corner part 321 is provided in an obtuse angle shape, the lifting corner part 321 is horizontally arranged, one end of the lifting corner part 321 extends into the space between the first conveying belt 11 and the second conveying belt 12, and since the cross section of the lifting corner part 321 is provided in an obtuse angle shape, it forms an inclined surface upward from the groove between the first conveying belt 11 and the second conveying belt 12, when the printed matter reaches this position, since the inclined surface is upward from the lower part of the conveying belt, at the same time, the inclined part 311 extends from the end of the limiting plate 111 to the second conveying belt 12, thus the printed matter is no longer kept horizontal during the movement, but has a certain inclination, thus the similar middle part of the printed matter first contacts the lifting corner part 321, so that the printed matter is lifted, and the side of the book page does not suffer damage since it contacts the lifting corner part 321 later.

[0023] After the printed matter is lifted, it needs to be considered to be turned over, thus the twisting part 322 is twistedly arranged from the horizontal state of the lifting corner part 321 to the vertical state of the vertical part 323, thus the book spine is contacted with the conveying belt downward by the arrangement of the twisting part 322, thus the printed matter is kept in a vertical state, thus it is turned over, the turning part 324 is arranged to be inclined to the left guide plate 31 from the vertical state of the vertical part 323. Thus the book is tilted to the guide part 313 of the left guide plate 31, and after the guide of the guide part 313, when it leaves the guide part 313, the turning over of the printed matter is realized.

[0024] The above is only the preferred embodiment of the present application, and is not intended to limit the present application in other forms, any skilled person in the art can change or modify the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still belongs to the protection scope of the technical scheme of the present application.
