Abstract
The invention discloses a printed matter flattening device which comprises a flattening plate, a vacuum generator, a negative pressure pipeline and a valve. The flattening plate is internally provided with a negative pressure cavity, and an air hole communicated with the negative pressure cavity is arranged on the upper surface of the flattening plate. One end of the negative pressure pipeline is connected with the vacuum generator, and another end of the negative pressure pipeline is connected with the negative pressure cavity. The valve is arranged on the negative pressure pipeline to be used for connecting and disconnecting the negative pressure pipeline. According to the printed matter flattening device provided by embodiments of the invention, when a printed matter is placed on the flattening plate, the vacuum generator can exhaust air of the negative pressure cavity to exhaust air between the printed matter and the flattening plate, so that the printed matter can be tightly fit on the flattening plate under the action of atmosphere, therefore, the printed matter is flattened, and the statuses of the printed matter, i.e. edge warping, bag concaveness, bag convex and the like can be avoided. The invention further discloses printed matter image detecting equipment comprising the printed matter flattening device.
Description
technical field [0001] The invention relates to the field of printing, in particular to a printed matter flattening device and a printed matter image detection device having the same. Background technique [0002] When collecting images of printed matter, the printed matter will have warped edges, bumps and other phenomena. As a result, the image quality of the collected printed matter is not high, which cannot meet the requirements of image detection. Contents of the invention [0003] The present invention aims at solving one of the above technical problems at least to a certain extent or at least providing a useful commercial choice. Therefore, an object of the present invention is to provide a printed matter flattening device for making the printed matter in a flattened state. [0004] Another object of the present invention is to provide a printed product image detection device having the above-mentioned printed product flattening device. [0005] The printed matte...
