Embodiment Construction

[0018] specific implementation plan

[0019] like Figure 1 to Figure 5 As shown, a curved paper flattening device for sprocket movement of a printing machine is composed of a vacuum pump 20, a quick-plug connector 21, an air pipe 22, a pressure equalizing box 24 and a regulating valve 23. The paper flattening device includes a suction Spreading plate assembly, air circuit device and blowing flattening device. The present invention is used in the traditional printing machine take-up cylinder 17, where the printing machine body is also equipped with a printing machine liner 1, a printing machine cylinder 2, a printing small cylinder 3, a printing machine upper pull shaft 4, and an upper holding shaft 5 , pull down shaft 12, hold down shaft 13, pull shaft 16 and delivery chain 18 after.

[0020] The air suction flat panel assembly 10 of the present invention is composed of an upper curved panel 101 and a lower curved panel 102, and the air suction flat panel assembly is locate...

Abstract

The invention belongs to a curved surface paper flattening device for chain wheel motion of a printing machine. The curved surface paper flattening device consists of a vacuum pump, a fast-inserting joint, an air pipe, a pressure-equalizing box and an adjusting valve. A paper flattening device comprises an air suction flattening plate assembly, an air path device and an air blowing flattening device, wherein the air suction flattening plate assembly consists of an upper curved surface plate and a lower curved surface plane; the air path device is used for generating negative pressure to a negative pressure air suction field and consists of the vacuum pipe, the fast-inserting joint, the air pipe, the pressure-equalizing box, a steel wire glue pipe and the adjusting valve; and the air blowing flattening device consists of an air blowing pipe, an upper guide bar and a lower guide bar. With the adoption of the curved surface paper flattening device, the paper curved surface flattening is performed by virtue of chain wheel motion in a large-format mode, so that a charged coupled device (CCD) camera acquires stable and high-definition images; and in addition, the curved surface paper flattening device also has the advantages of reasonable structure design, simplicity in operation, convenience in mounting and debugging and good detection quality.

Description

[0001] technical field [0002] The invention belongs to a curved paper flattening device used for the movement of the sprocket wheel of a printing machine. Background technique [0003] The printing quality online inspection system of printing paper uses a line array CCD camera to collect the entire printed product image through video splicing technology. The sprocket part of the printing machine is the main image acquisition area of ​​the detection system. Due to the large field of view of the imaging system, the pixel distribution rate of the CCD camera is as high as 0.08mm×0.08mm / pixel, and the format of the large printing paper is 800mm×600mm. The printing paper to be tested, especially the large format printing paper to be tested, must ensure that the printing paper surface is flat when passing through the image acquisition area of ​​the sprocket part of the printing machine, otherwise it will cause false detection. That is to say, in order to ensure the image qua...
