The invention provides screen frame positioning equipment and a screen frame positioning method. The screen frame positioning equipment comprises a base, a worktable, a conveying device, a driving device, guide rails, positioning pillars, a dual-rod left-and-right positioning cylinder, a positioning push block, an artificial screen frame positioning device, a cross beam, a cross beam cylinder and a scraper assembly. The screen frame positioning equipment and the screen frame positioning method have the benefits that the mounting and dismounting are convenient, and a screen frame does not need to be changed; the safety is achieved, the manual positioning can be simulated, and the positioning is accurate; after power failure, the manual operation can be automatically converted; panels are called out, the overprinting is accurate, and the efficiency is high.

A print medium, on which individual labeling information made up of one or more labeling elements that are selectively shown, of common labeling information made up of a plurality of labeling elements, is formed by a printing device, wherein the common labeling information is printed in advance and a background color of an area where at least a plurality of labeling elements is printed is a print color that is printable by the printing device, is disclosed.

The invention discloses a multi-functional micro-nano structured color film production equipment and a working method, comprising: an unwinding device for unwinding the plastic film; a traction device for pulling the plastic film forward; a gravure printing device for unwinding the plastic film Graphic printing; the first oven heating system, drying the printing ink on the plastic film; the scraper coating device, coating the resin layer on the surface of the plastic film; the second oven heating system, drying the resin layer on the plastic film; micro-nano structure The embossing device is used to emboss micro-nano structure patterns; the cooling device is used to cool the plastic film; the winding device is used to rewind the plastic film; the bridge guide roller is used to guide the film feeding; The structural embossing device realizes the overprinting of printed graphics and micro-nano structured graphics. The invention can realize the production of the micro-nano structural color thin film, and can print without ink or a very small amount of environmentally friendly ink.

The invention discloses a holographic positioning overprinting method between coils and belongs to the field of anti-counterfeiting printing technology. Substantially, a holographic pattern on a drum holographic anti-counterfeiting film is positioned and overprinted on a drum printing stock; and the method is characterized in that: 1) each specific pattern or each group of specific patterns on the drum holographic anti-counterfeiting film and the drum printing stock have an axial positioning cursor; 2) the drum holographic anti-counterfeiting film and the drum printing stock are put into an overprinter unwinding device, respectively pass through a traction roll and enter an overprinting device; after overprinting, the anti-counterfeiting film is stripped and winding is performed; and before overprinting, the two kinds of drums are respectively horizontally and axially positioned and then subjected to continuous overprinting. The method can realize accurate and continuous overprinting between the coils, improve overprinting accuracy and efficiency and reduce the reject rate.

The utility model relates to a large embossing cylinder of a satellite type flexographic printing machine. The purpose of the invention is to solve the problems of inaccurate overprinting and overall pattern deviation in existing satellite flexo printing machines that use entrainment, and the problem that the groove jaw structure cannot be directly introduced to improve printing quality. Main points of the technical solution: It is a cylindrical body with a central axis, and its characteristics are: the arc surface of the cylindrical body has one or more grooves distributed along the circumferential direction, and each groove is rotated and fitted with a The jaw shaft is arranged in the axial direction. Several jaws are fixed on the jaw shaft. The claw end of the jaw matches the edge of the notch of the groove. The driving end of the jaw shaft protrudes from the side of the cylinder. Each groove One or more entrainment bridge plates arranged along the circumferential direction for supporting entrainment are provided on the notches, and the top surface of the entrainment bridge plate is an arc surface with the same radian as the arc surface of the cylinder.

The invention relates to a printing mechanism and a printing method for synchronizing digital printing and rotary screen printing. It is still difficult to effectively combine digital and rotary screen printing to complete the printing method of synchronous overprinting. The steps of the printing method of the present invention are as follows: (1) use a rotary screen to print on the printed fabric to form a screen printing pattern; (2) designate feature points on the screen printing pattern, and use the front camera to take pictures of the features in the front and back of the two flowers. Points to get the deviation value of the rotary screen; (3) According to the deviation value of the rotary screen, the digital printing pattern is scaled accordingly, and after digital printing, a combined printing pattern is formed on the printed fabric; (4) After using the The camera shoots the combined printing pattern or the corresponding feature points of the screen printing pattern and the digital printing pattern, detects whether there is a deviation between the digital printing and the rotary screen printing, and judges whether the effect of accurate overprinting has been fully achieved. The invention effectively combines the respective advantages of digital printing and traditional rotary screen printing.

The invention relates to a printer transmitter of planet flexible printer. Wherein, it comprises printing larger roller on the frame, several printer units, and transmitter. The invention is characterized in that: the arc surface of roller has one or more grooves along the axles; each groove has rotational claw axle along the axle fixed with several claws; the end of claw is matched with the cut of groove; the driver of claw axle is extended outside one side of roller; the cut is arranged with one or several clamping plates along circumference to support the clamping band, whose top surface is arc same as the arc surface.
