Problems solved by technology

The base material of the paper-plastic bag, during the storage process, due to the influence of the environment and storage time, will cause a certain amount of static electricity on the base material, and during printing, the ink has poor antistatic properties, which makes the ink lubricity poor, causing the ink to adhere to the base material. The effect on the material is not good, so that the printing effect of the paper-plastic bag is not good
Secondly, due to the problem of ink processing technology, the fineness of the ink is not enough, and the pigment particles are too large, which will also reduce the printing effect of the substrate.

Embodiment 1

[0043] A paper-plastic packaging bag processing technology, using a paper-plastic printing equipment, basically as attached figure 1 As shown, the paper-plastic printing equipment includes a discharge roller 5, a printing box 1 and a take-up roller 2 in sequence from left to right. combined with figure 2 As shown, the winding roller 2 and the discharging roller 5 are all rotatably mounted on the frame 13, and the winding roller 2 and the discharging roller 5 are respectively driven by two unidirectional motors (not shown in the figure).

[0044] as attached image 3 And attached Figure 4 As shown, a sufficient amount of substrate 11 is wound on the winding roller 2, and the substrate 11 is the printing substrate, that is, the printing material before the paper-plastic packaging bag is formed. The top wall of the printing box 1 has a window, and the window is provided There is a baffle plate 3 that is rotatably connected with the printing box 1, and a placement plate 31 we...

Embodiment 2

[0058] The difference between embodiment two and embodiment one is that, as attached Figure 6 And attached Figure 7 As shown, the air outlet of the first pump assembly pump is connected to an upper dust removal box 151 through a pipeline, and water is housed in the upper dust removal box 151. The air curtain pipe 16 on the box 1, the communicating place of the pipeline and the upper dust removal box 151 is located above the liquid level.

[0059] The air outlet of the second pump assembly is connected to the lower dust removal box 152 through a pipeline, and is located below the fixed roller. The upper part of the lower dust removal box 152 has a tapered opening in longitudinal section, and a liquid inlet unit is fixed in the opening by fastening bolts. To the valve 153 , the liquid inlet check valve 153 communicates with the bottom of the lower dust removal box 152 , and the ink in the opening enters in the lower dust removal box 152 through the liquid inlet check valve 15...

Abstract

The invention relates to the technical field of printing, and discloses a process for processing a paper-plastic packaging bag. The method comprises the following steps of S1, conveying a base material towards a static elimination shaft, enabling the upper surface of the base material to adhere to the lower surface of the static elimination shaft, and conducting static on the static elimination shaft to the ground; S2, transporting the base material to the position between an upper roller and a lower roller, and conducting intermittent dust suction on the upper surface of the base material through the upper roller; S3, conveying the base material obtained after dust removal in the step S2 towards a printing roller, and conducting printing on the upper surface of the base material through aprinting roller; S4, transporting the printed base material in the step S3 towards a dryer until the dryer dries ink on the surface of the base material; and S5, collecting the base material througha winding roller to complete printing of the base material. By means of the printing process, the static on the base material can be reduced, the base material is leveled, and the printing effect is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a processing technology of a paper-plastic packaging bag. Background technique [0002] Paper-plastic bags, also known as three-in-one composite paper bags, are composed of plastic and kraft paper. Usually, the plastic layer uses pp polypropylene (pp) as the base material of pp silk woven cloth, and the kraft paper uses refined composite kraft paper. It is formed by thermal lamination of molten plastic, kraft paper coated cloth is formed into a bag, and then processed and sewn into a three-in-one paper-plastic bag. [0003] The paper-plastic bag needs to be printed before it is made into a bag, that is, the pattern is printed on the paper-plastic bag. The base material of the paper-plastic bag, during the storage process, due to the influence of the environment and storage time, will cause a certain amount of static electricity on the base material, and during printing, the ink...
