Description

Technical Field

[0001] The utility model relates to the technical field of deviation correction of printing machines, in particular to a paper deviation correction device used in printing technology. Background Art

[0002] Paper deflection during the printing process may cause problems such as distortion, color difference, and position offset of the printed pattern. Therefore, measures need to be taken to avoid and deal with it. There are many reasons for paper deflection, which is generally caused by the deviation of the transmission roller and transmission belt. The current paper correction device is simple in design, and generally realizes the correction and limit of the paper by setting a limit mechanism. Some also realize the correction of the paper through an auxiliary traction mechanism. When one side of the paper is deflected, the traction speed of the edge is accelerated. Despite this, the current equipment still has some shortcomings. First, when the paper is deflected during operation, the device cannot detect it in the first time to detect the deflection signal of the paper, and then control the corresponding correction tooling to realize the correction processing at the corresponding edge of the paper. Secondly, the transmission stability of the correction tooling is not ideal, resulting in poor correction effect, so it needs to be improved. Utility Model Content

[0025] It should be noted that the conveyor belt 2 is arranged on the frame 1 to realize the transmission of paper and then the printing processing of paper. By installing the correction tool 3 on the frame 1, the correction processing when the paper is offset is realized. The correction tool 3 is assembled by the bracket 301, the motor 302, the active shaft 303 and the passive shaft 305. The motor 302 can drive the active shaft 303 to rotate, and then the auxiliary transmission of the paper is realized through the active shaft 303 and the passive shaft 305. It should also be noted that the motor 302 works normally when the paper is normally transmitted, and the speed is accelerated when correction processing is required to realize the correction of the paper; by fixing the mounting frame 6 on the frame 1, the mounting frame 6 is set for the correction detection group The installation of component 7, the correction detection component 7 includes a protective tube 701, a circular plate 703, a static contact 704, a top cover 705, a moving contact 706, a telescopic rod 707, etc. When the paper is offset, the telescopic rod 707 can be driven to move upward, and then the moving contact 706 and the static contact 704 are closed. The static contact 704 and the moving contact 706 are connected in series with the corresponding motor 302. In actual use, a power supply can be added to the circuit, and the power supply frequency of the motor 302 can be increased (achieved through a frequency converter, which is a known prior art).

The base 708 and the universal ball 709 are both located in the gap between the frame 1 and the conveyor belt 2.
