Embodiment 1

[0066] This embodiment is to use the die-cutting and completely waste-removing paper press mechanism of the present invention to produce die-cutting and completely waste-removing plate products of the main color blue printing plate product of the soft box cigarette wrapping paper of the specification of 100.8mm*155mm, and the gram weight is 95g / m 2 The light column sprayed aluminum cardboard, the paper width is 630mm, and the circumference of the printing plate is 621.24mm (equivalent to the diameter of the printing plate roll is 197.747mm). Pattern engraving parameters: the screen line number range is 90l / cm, the dot size is 96±1μm, the dot edge wall width range is 15±1μm, and the cell depth range is 23±1μm. The highest production printing speed can reach 200m / min.

[0067] After using this scheme, the amount of solvent added in the production process is reduced, the ink viscosity can be increased from 16 seconds to 22 seconds, and the amount of solvent added is reduced by ...

Embodiment 2

[0069] This embodiment adopts the die-cutting full-cleaning waste pressing mechanism of the present invention in the die-cutting and full-cleaning production of the main color red printing plate product of the 98mm*233mm specification carton wrapping paper, and the gram weight is 225g / m when printing 2 The light column sprayed aluminum cardboard, the paper width is 730mm, and the circumference of the printing plate is 592.89mm (equivalent to the diameter of the printing plate roll is 188.722mm). Pattern engraving parameters: screen line number range is 70l / cm, dot size is 124±1μm, dot edge mesh wall width is 18±1μm, and cell depth is 28±1μm. The highest production printing speed can reach 200m / min.

[0070] To sum up, in the die-cutting all-waste-removing paper pressing mechanism of the present invention, during the die-cutting process, the anti-slip rubber block presses the paper under the elastic force of the spring, and its force mode is a point force mode. During operatio...

Abstract

The invention provides a die-cut full-clean waste paper pressing mechanism. The die-cut full-clean waste paper pressing mechanism comprises a plurality of paper pressing devices and a plurality of paper pressing regulators. The paper pressing devices are fixed to the lower ends of the paper pressing regulators. Each paper pressing device comprises an antiskid rubber block and a plurality of paperfixing ejector pins. Each paper pressing regulator comprises a support rod and a support sleeve rod, wherein each support rod can slide through the corresponding support sleeve rod. A spring is arranged at the lower end of each support sleeve rod. Each support rod is sleeved with the corresponding spring. A paper pressing mechanism pressure adjusting nut is arranged at the upper end of each support rod. Limiting rings are correspondingly arranged at the lower end of each support rod and the lower surface of each support sleeve rod. The springs abut against the limiting rings. The paper fixingejector pins are fixedly connected with the lower ends of the support rods. The die-cut full-clean waste paper pressing mechanism is of a single-point type paper pressing structure, and when the middle part of the edge of product waste material paper cannot be pressed tightly, the problem that pressing is not tight can be solved by adjusting the paper pressing device at the problem portion; and the paper pressing devices are not easy to damage, and even if some paper pressing device is damaged, the damaged paper pressing device only needs to be replaced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of packaging and printing, in particular to a paper pressing mechanism in a paper blank separation device of a die-cutting full-blank process. Background technique [0002] The die-cutting full cleaning process in the post-press processing process during printing is mainly composed of three parts: molding, waste cleaning device, and paper blank separation device. The paper blank separation device is mainly composed of upper and lower paper blank separation devices. There is a pressing device for fixing the waste in the upper paper blank separation device. The main function of this device is to fix the waste, so that the product can be separated from the paper edge smoothly and enter the lower paper blank separation frame. [0003] The paper pressing device currently used on the die-cutting machine is an integral structure, such as figure 1 As shown, the structure mainly includes: a paper press steel bar 6 and an anti...
