The utility model relates to the technical field of stamping, in particular to an intelligent stamping, authentic identification and batch stamping all-in-one machine. According to the automatic stamping machine, the scanning mechanism, the printing mechanism, the paper conveying mechanism and the stamping mechanism are arranged, scanned files are separately conveyed through the paper conveying mechanism, files needing to be stamped and files not needing to be stamped are separately conveyed through channels, the paper conveying efficiency is improved, and then the stamping efficiency is improved.

The invention provides a pixel reading circuit and a control method thereof, and the pixel reading circuit comprises a photoelectric conversion module, a gain adjustment module, a correlated double sampling module, a gain control feedback module and an output module. The gain adjusting module is used for carrying out integral processing on the light current signal to obtain integral voltage, the correlated double sampling module is used for sampling the integral voltage to obtain effective signal voltage, and the gain control feedback module is used for generating a gain control signal based on the effective signal voltage so as to adjust integral gain. And the output module buffers and outputs the effective signal voltage. According to the circuit provided by the invention, the correlated double sampling function is integrated in the pixel, the number of used switches is small, time sequence control is simple, the pixel area is reduced, the chip integration degree is high, multiple times of transmission of signals between the pixel and the column-level circuit is avoided, the processing pressure of the column-level circuit is relieved, and the system frame rate is improved.

The utility model relates to the technical field of textile printing, and discloses a rotary screen and ink jet composite printing machine which comprises two side frames, a guide belt, a guide belt driving mechanism, a rotary screen printing roller and at least one digital direct injection mechanism. The digital direct injection mechanism comprises a portal frame, a printing assembly and a lifting assembly. And a spray head on the printing assembly faces the guide belt downwards. According to the rotary screen and ink-jet composite printing machine, part of a rotary screen structure of an original rotary screen printing machine is removed, a vacant position is replaced with a digital direct injection mechanism, original side frames, guide belts, guide belt driving mechanisms and other core components are fully utilized, a whole set of transmission system does not need to be redesigned or purchased, and the equipment upgrading cost is remarkably reduced; in addition, the portal frame of the digital direct injection mechanism is placed on the ground, can be rapidly installed through hoisting, is not in complex mechanical connection with an original machine structure, and is short in transformation period and convenient to operate.

The invention provides a U-shaped stirrup heating-bending integrated device for a fiber reinforced thermoplastic resin composite material rib and a bending method, and belongs to the field of stirrup heating-bending devices. The problems that an existing bending device is low in heating-bending efficiency, stirrups with different bending angles cannot be prepared, and on-site rapid bending cannot be achieved are solved. The device comprises a platform, two synchronous guide rails, a semi-open type heating cabin, two sliding feeding brackets, a U-shaped stirrup mold, two rotating angle discs and two bending columns, the semi-open type heating cabin is installed on the platform, the two sliding feeding brackets are located on the two sides of the semi-open type heating cabin, one sides of the two synchronous guide rails are correspondingly connected with the two sliding feeding brackets, and the other sides of the two synchronous guide rails are correspondingly connected with the U-shaped stirrup mold. And the other sides of the two synchronous guide rails are located on the two sides of the U-shaped stirrup mold, two rotating angle discs are correspondingly arranged in front of the two synchronous guide rails, and bending columns are installed on the rotating angle discs. The process is integrated and automatically controlled, repeated carrying in the traditional process is avoided, and the strength loss is reduced.
