Description

Technical Field

[0001] The utility model relates to the technical field of digital printing, in particular to a digital printing unwinding structure. Background Art

[0002] Digital printing is a modern, digitized form of printing technology. It generally refers to the partial or complete digitization of the entire printing process. Digital printing is a new printing method that prints computer files directly on paper. This process eliminates the tedious plate making and proofing steps in traditional printing.

[0003] The technical principle of digital printing is the process of directly converting digital information into printed materials using a digital printing system. The digital original can be a digital file processed by a digital prepress system, or it can originate from the internet or digital media. The digital printing system encompasses technologies such as computer-to-plate, digital workflow, digital proofing, and on-demand rapid printing. Digitally printed materials are rotated by an unwinding air shaft and then pass through a web-correcting mechanism, a corona device, a dust removal mechanism, a flexographic plate holder, and a hot stamping rewinding mechanism.

[0022] During work, the staff transports the printing material to one side of the digital printing machine 1, and uses the telescopic cylinder 3 to move the connecting shaft 4 downward. The movement of the connecting shaft 4 causes the winding air-expanding shaft 2 to move together. After the winding air-expanding shaft 2 moves, it is convenient for the staff to install the printing material on the winding air-expanding shaft 2, and then reset the winding air-expanding shaft 2 through the telescopic cylinder 3. During work, the printing material is processed by the No. 1 flexographic plate seat 5, the No. 2 flexographic plate seat 6 and the No. 3 flexographic plate seat, and then is cold-ironed by the No. 1 conveyor roller 9.

[0023] The cold stamping unit includes a hot stamping rewinding and unwinding mechanism 8; the hot stamping rewinding and unwinding mechanism 8 is arranged at the top of the digital printing machine 1, and the hot stamping rewinding and unwinding mechanism 8 is arranged on one side of the No. 3 flexographic plate seat 7; the side end of the hot stamping rewinding and unwinding mechanism 8 is rotatably connected to multiple groups of No. 1 conveying rollers 9.

[0024] The cold foil structure of the hot stamping reel-up and rewind mechanism 8 and the No. 1 conveyor roller 9 transfers the metal or coating layer on the hot stamping foil to the printing material, such as paper or plastic film, through precise control and mechanical devices. The cold foil structure can ensure the precise transfer of the hot stamping foil, including fine dots, lines and complex patterns, thereby achieving a high-precision hot stamping effect.

[0025] The adjustment unit includes an electric slide rail 10 ; the electric slide rail 10 is fixedly connected to the top of the digital printing machine 1 ; a guide block is fixedly connected to the bottom end of the hot stamping rewinding and unwinding mechanism 8 ; the guide block is slidably connected to the top of the electric slide rail 10 .

[0026] The positions of the hot stamping rewinding and unwinding mechanism 8 and the No. 1 conveyor roller 9 can be adjusted according to the processing requirements of the printed materials. A guide block is fixed to the bottom end of the hot stamping rewinding and unwinding mechanism 8, and the guide block corresponds to the electric slide rail 10. The guide block can be slid by the electric slide rail 10, thereby causing the hot stamping rewinding and unwinding mechanism 8 to slide together, and then the work station can be quickly switched according to the processing requirements of the printed materials.

[0028] When the printed material passes through the interior of the corona mechanism 12, the cooperation of the No. 2 corona roller 15 and the No. 1 corona roller 14 can perform corona treatment on both sides of the printed material. Corona treatment generates low-temperature plasma on the surface of the material through high-frequency, high-voltage discharge, causing physical and chemical changes on the plastic surface, such as chemical bond breaking, degradation, and the generation of free radical reactions. These changes help to increase the roughness and surface area of the material surface, thereby increasing its surface tension.

The side end of the cleaning brush 17 is connected to a motor, which rotates the cleaning brush 17. The rotation of the cleaning brush 17 and the friction with the surface of the printing material will remove the dust. The negative pressure generated by the vacuum pump 18 is discharged through the powder suction pipe 19. The powder suction pipe 19 can absorb the dust cleaned by the cleaning brush 17 to prevent the dust from spreading.

[0031] A side end of the digital printing machine 1 is fixedly connected with a deviation correction mechanism 11 ; the deviation correction mechanism 11 is arranged above the wind-up air-inflating shaft 2 .

[0032] The printed material on the winding air-inflating shaft 2 needs to be rotated and conveyed by the correction mechanism 11 first. If the printed material is shifted during the conveying process, the correction mechanism 11 can be used to adjust it.

[0033] The working principle of the utility model is as follows: when working, the staff transports the printing material to one side of the digital printing machine 1, and uses the telescopic cylinder 3 to move the connecting shaft 4 downward, and the movement of the connecting shaft 4 causes the winding air-expanding shaft 2 to move together.

The electric slide rail 10 can make the guide block slide, so that The hot stamping rewinding and unwinding mechanism 8 slides together, and the workstation can be quickly switched according to the processing requirements of the printed material; the printed material on the rewinding air-inflating shaft 2 needs to be rotated and conveyed through the correction mechanism 11 first. If the position of the printed material is offset during the conveying process, it can be adjusted through the correction mechanism 11; when the printed material passes through the inside of the corona mechanism 12, the cooperation of the second corona roller 15 and the first corona roller 14 can perform corona treatment on both sides of the printed material. The corona treatment generates low-temperature plasma on the surface of the material through high-frequency and high-voltage discharge, which makes the plastic surface produce physical Physical and chemical changes, such as chemical bond breaking, degradation, and free radical reactions, etc., these changes help to increase the roughness and surface area of the material surface, thereby increasing its surface tension; when the printing material is transported to the interior of the dust removal mechanism 13, it is transported by the No. 2 conveying roller 16, and the side end of the cleaning brush 17 is connected to a motor, which rotates the cleaning brush 17.
