Description

Technical Field

[0001] The utility model belongs to the technical field of digital printing equipment, and more specifically relates to a multi-nozzle digital printing equipment. Background Art

[0002] At present, in large-scale digital fabric printing equipment with multiple nozzles (dozens or hundreds of nozzles), all nozzles are concentrated on the nozzle plate at the bottom of the printing head, and many ink supply cartridges are set above it. A control system is also set inside the printing head. The settings of various structures, ink supply pipelines and circuits make the printing head large and heavy. When printing, the printing head needs to move vertically in the direction of fabric conveying, so a beam is needed for support, and the printing head is slidably connected to the beam.

[0003] At present, the printing head of most of the above-mentioned digital printing machines is slidably connected to one side of the beam, that is, a slide block is set between the side of the beam and the box of the printing head, and a servo drive device is set to drive the printing head to move. For example, a multi-nozzle digital printing machine disclosed in Chinese patent publication number CN214646860U has a printing head protruding on one side of the beam, so that the weight of the printing head is all located on one side of the beam, and when printing, the printing head needs to move back and forth for a long time, which easily causes the beam to tilt and affect the printing accuracy. At the same time, the protruding printing head makes the conveyor belt at the front end of the conveying device longer, resulting in a large overall space occupied by the equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a multi-nozzle digital printing device that allows a crossbeam to pass through a printing head and hang it on the crossbeam, thereby preventing the crossbeam from tilting and affecting printing accuracy, while reducing the protruding distance of the printing head on the crossbeam and the size of the device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-nozzle digital printing device, comprising a conveying device, a beam, a pillar and a printing head slidably connected to the beam, the printing head comprising a chassis, a support plate is arranged in the chassis, the beam passes through the middle of the chassis, the support plate and the beam are slidably connected, a linear motor is arranged between the support and the beam, and the ink supply mechanism and the nozzle in the chassis are both located under the beam.

[0006] Furthermore, the support plate is located below the cross beam, a plurality of sliders are arranged on the support plate, a guide rail is arranged on the lower surface of the cross beam, and the sliders are slidably connected to the guide rail.

[0007] Furthermore, two parallel guide rails are arranged between the support plate and the crossbeam, and the linear motor is located between the two guide rails.

[0008] Furthermore, the ink supply mechanism in the chassis is installed below the support plate and connected to the support plate.

[0009] Furthermore, baffles located on both sides of the crossbeam are arranged on the support plate, and a printing control system is located on the baffles.

[0010] Furthermore, the support plate is located above the crossbeam, a guide rail is arranged on the upper surface of the crossbeam, and a plurality of sliders are arranged on the support plate, and the sliders are slidably connected to the guide rail.

[0011] Compared with the prior art, the beneficial effect of the utility model is that when the crossbeam passes through the chassis of the printing head, the load of the crossbeam is changed from one side to the middle, thereby preventing the crossbeam from tilting due to the force on one side, affecting the printing accuracy, and at the same time reducing the protruding distance of the printing head, which can reduce the total conveying length of the conveyor belt and reduce the overall volume of the equipment.
