Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printing, in particular to a plasma surface treatment feeding mechanism for a digital inkjet printing system. Background Art

[0002] Inkjet printers convert liquid ink into tiny particles through a nozzle and spray them onto the substrate. The ink enters the ink cartridge through the ink bottle and then passes through the ink cartridge to the print head for inkjet printing.

[0003] The most common printing substrate is paper, but for some substrates with coatings on the surface, such as UV coatings, plastic film coatings, etc., it is difficult for the ink to be absorbed by them during printing, which results in poor printing quality, incomplete patterns, and susceptibility to external scratches. The existing solution is to pre-corona treat this type of substrate, that is, before entering the inkjet printer, the substrate is first manually corona treated by a plasma surface treatment machine, and the molecular structure of the surface of the substrate such as plastic film is destroyed by corona discharge, so that the surface is oxidized and polarized in minutes, and the surface is eroded by ions, thereby increasing the adhesion ability of the substrate surface. Finally, the printing ink can be well attached to the surface of the substrate; then the treated substrate is placed on the conveyor of the digital inkjet printer for subsequent printing.

[0004] The existing plasma surface treatment machine mainly includes a plasma surface treatment body and a corona nozzle that are interconnected. Due to the inherent structure of the existing digital inkjet printer, there is currently no good solution for how to implant it into the digital inkjet printing conveyor line and ensure that the printed material can be accurately transmitted from under the corona nozzle to achieve automated operation.

[0005] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and provide a plasma surface treatment feeding mechanism for a digital inkjet printing system, which is used to solve the technical problem that traditional digital inkjet printers cannot achieve accurate and automated corona treatment of the fed substrates.

[0009] A corona material blocking mechanism capable of acting on the belt conveyor line is also arranged below the corona slide rail, and is used for blocking and limiting the printing material that travels below the corona nozzle.

[0010] Furthermore, there are two corona nozzles, which are symmetrically arranged on both sides of the corona slider.

[0011] Furthermore, the corona material blocking mechanism includes a material blocking slide bracket symmetrically arranged with respect to the corona slide rail axis; two ends of two material blocking slides of the same specifications are movably connected to the two material blocking slide brackets respectively, and material blocking side plates are respectively connected to the bottom of the two material blocking slides.

[0012] Furthermore, the feed ends of the two material-blocking side plates form a wide opening.

[0013] Furthermore, the material blocking slide plate bracket includes material blocking pillars symmetrically arranged on both sides of the belt conveyor line, and the tops of the two material blocking pillars are connected with material blocking slide bars;

[0014] Both ends of the material blocking slide plate are provided with material blocking sleeve holes for sleeve-mounting the material blocking slide rod.

[0015] Furthermore, the two material blocking sliding bars are parallel to each other, and the heights of the two material blocking sliding bars are lower than the height of the corona slide rail.

[0016] Furthermore, a material-blocking threaded hole connected to the material-blocking sleeve hole is also provided on the material-blocking slide plate, and the material-blocking slide plate and the material-blocking slide rod are locked by screwing the material-blocking threaded hole to the material-blocking knob screw.

[0017] Furthermore, both ends of the material blocking slide plate are connected to the material blocking side plates through material blocking connecting plates respectively.

[0018] Furthermore, vertical material-blocking waist-shaped grooves are respectively provided at both ends of the material-blocking slide plate, and correspondingly, a material-blocking locking hole for tightening a material-blocking locking screw is provided at the upper end of the material-blocking connecting plate, and the material-blocking locking screw passes through the material-blocking waist-shaped groove and is screwed into the material-blocking locking hole.

[0019] Furthermore, an N-shaped material blocking cover shell matching the outer shapes of the corona support and the corona slide rail is sleeved on the outer sides thereof.

[0020] Beneficial Effects

[0021] The plasma surface treatment feeding mechanism for the digital printing system provided by the utility model realizes width adjustment on the belt conveyor line by means of corona brackets across both sides of the belt conveyor line and sliding connection between the corona nozzle and the corona nozzle; the corona blocking mechanism realizes the limited transmission of the substrate entering the belt conveyor line to ensure that it is accurately guided to the bottom of the corona nozzle. This mechanism can not only perform plasma surface treatment on the substrate being transmitted, but also ensure that the substrate can accurately enter the corona area. While ensuring the plasma surface treatment of the substrate, it has low manual dependence and can effectively provide printing efficiency and quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A corona material blocking mechanism 5 capable of acting on the belt conveyor line 17 is also provided below the corona slide rail 2, for blocking and limiting the printing material that is traveling below the corona nozzle 4, so as to ensure that the printing material can accurately pass under the corona nozzle 4 when being transferred on the belt conveyor line 17;

[0030] Specifically, the corona nozzle 4 in this embodiment further includes a plasma surface treatment body, which is arranged in a cabinet of the digital printing system and is used to control the start and stop of the corona nozzle 4 .

[0032] As a specific embodiment of the present scheme, there are two corona nozzles 4, which are symmetrically arranged on both sides of the corona slider 3; by manually moving the corona slider 3, the widthwise position of the corona nozzle 4 relative to the belt on the belt conveyor line 17 can be adjusted to adapt to substrates of different shapes;

[0033] In addition, since the printing material is driven on the belt conveyor line 17, the provision of two corona nozzles 4 can ensure full coverage of the plasma surface treatment and improve the treatment quality.

[0034] On the other hand, an n-shaped material blocking cover 19 matching the shape is also provided on the outer side of the corona support 1 and the corona slide rail 2 to protect the support formed by the corona support 1 and the corona slide rail 2 and further protect the corona nozzle 4.

[0041] In addition, both ends of the material-blocking slide plate 9 are connected to the material-blocking side plates 10 via material-blocking connecting plates 14 .

[0042] Specifically, vertical material-blocking waist-shaped grooves 15 are respectively provided at both ends of the material-blocking slide plate 9, and correspondingly, a material-blocking locking hole 16 for tightening a material-blocking locking screw 18 is provided at the upper end of the material-blocking connecting plate 14, and the material-blocking locking screw 18 passes through the material-blocking waist-shaped groove 15 and is screwed into the material-blocking locking hole 16; through this structure, the distance between the material-blocking side plate 10 and the material-blocking slide plate 9 can be adjusted, and then the adjustment can be used to adapt to belt conveyor lines of different heights.
