Description

Technical Field

[0001] The utility model relates to the technical field of tipping paper inkjet coating, in particular to a low-quantity inkjet coating device. Background Art

[0002] During the production and processing of tipping paper, the high-temperature atomized ink needs to be sprayed onto the surface of the tipping paper through an atomizing nozzle. During the spraying process, the ink on the surface of the tipping paper is dried by hot air, so that an antibacterial and waterproof ink layer is formed on the surface of the tipping paper, thereby improving the water resistance and antibacterial properties of the tipping paper product.

[0003] When ink is sprayed on the tipping paper, the release roller rotates to release the tipping paper, and the take-up roller rotates to take up the tipping paper, so that the tipping paper passes through the inkjet coating device. During this process, the atomizing nozzle on the device sprays the ink onto the surface of the tipping paper, and the hot air blower blows hot air to the ink through the pipeline to solidify the ink onto the tipping paper.

[0004] Most inkjet coating devices are only suitable for inkjet coating of one width of tipping paper. When the width of the tipping paper is small, the inkjet coating device will still spray ink onto the tipping paper with a smaller width according to the larger width. This will cause some ink sprayed from the atomizing nozzles to not fall on the tipping paper, which is prone to waste ink. In addition, the hot air blower used to dry the ink can only simply dry the ink, and cannot assist in cleaning and drying the tipping paper at the same time. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1-4 In an embodiment of the utility model, a low-quantity inkjet coating device includes a bottom plate 100, a side plate 110 and a side plate 2 120 are fixed to the top surface of the bottom plate 100, a support plate 111 for supporting tipping paper is fixed between the side plate 110 and the side plate 2 120, an inkjet air-drying mechanism 200 is arranged above the support plate 111, and the inkjet air-drying mechanism 200 includes a carrier plate 210 fixedly connected to the side plate 110, a crossbeam 220 is fixed to one end of the carrier plate 210, and an air supply pipe 230 and an inkjet pipe 250 are rotatably connected at both ends of the crossbeam 220, and the air supply pipe 230 An air drying box 240 and an inkjet cartridge 260 are respectively connected and fixed to the bottom end of the inkjet tube 250, a driving mechanism 270 for driving the air supply pipe 230 and the inkjet tube 250 to rotate is arranged on the top of the carrier plate 210, an ink box 300 for conveying ink to the inkjet cartridge 260 is fixed to the top surface of the bottom plate 100, a hot air blower 400 is fixed to the top surface of the bottom plate 100, an air cylinder 500 for conveying hot air to the air drying box 240 is connected and fixed to the air outlet end of the hot air blower 400, a cleaning roller 600 for cleaning paper scraps and dust on the surface of the cork paper is arranged between the air cylinder 500 and the side panel 110.

[0026] Specifically, the inkjet cartridge 260 and the air-drying box 240 are connected and rotated above the tipping paper. When encountering tipping paper with a smaller width, the driving mechanism 270 is used to rotate and tilt the inkjet cartridge 260 and the air-drying box 240, so that the multiple atomizing nozzles 261 on the inkjet cartridge 260 and the mesh holes on the air-drying box 240 can be completely covered by the tipping paper, and then the mesh holes on the bottom of the air-drying box 240 can blow all the hot air onto the tipping paper, so that the atomizing nozzles 261 on the bottom of the inkjet cartridge 260 can spray all the ink onto the surface of the tipping paper. By rotating the inkjet cartridge 260 and the air-drying box 240 to different tilt angles, it is convenient to spray ink on tipping papers of different widths and fully dry the ink.

[0034] In the specific implementation, the conveying paper is arranged on the support plate 111, the release roller at one end of the tipping paper rotates to release the tipping paper, and the winding roller at one end of the tipping paper rotates to wind up the tipping paper, so that the tipping paper to be sprayed with ink can be conveyed to the bottom of the inkjet air-drying mechanism 200, and the electric push rod 271 drives the two racks 273 on the transmission rod 272 to mesh with the gear for transmission, and the gear drives the air supply pipe 230 and the inkjet pipe 250 to rotate, thereby causing the air-drying box 240 and the inkjet box 260 to rotate and tilt, so that the water The surface of the loose paper can cover multiple atomizing nozzles 261 on the bottom of the inkjet cartridge 260, and then the oil pump 311 pumps the ink inside the ink box 300 to the inside of the inkjet cartridge 260 through the oil pipe 310, and then sprays it onto the surface of the loose paper through the atomizing nozzle 261. At the same time, the hot air blower 400 delivers hot air inside the air duct 500, and the hot air is delivered to the inside of the air drying box 240 through the air pipe 2 510, and then blows toward the ink on the surface of the loose paper from the mesh one position, so as to facilitate drying of the ink.

[0035] Embodiment 2, based on embodiment 1, is to make the hot air blown out by the hot air blower 400 not only dry the ink, but also achieve the effect of auxiliary drying and cleaning the tipping paper.

[0037] Specifically, when the hot air is blown into the air duct 500, the hot air will drive the multiple blades 611 to rotate with the support tube 610 as the axis, so that the support tube 610 can synchronously drive the roller 620 and the brush 630 to rotate to clean the impurities on the surface of the kraft paper, so as to facilitate the hot air to be used as power to drive the brush 630 to clean the kraft paper to be sprayed with ink.

[0038] like Figure 2 and Figure 5 As shown, in this embodiment, a plurality of circular holes 612 penetrating the drum 620 are evenly opened at equal angles in a ring shape on the outer side of the support tube 610, a dust box 112 is arranged on one side of the drum 620, a mesh hole 2 is opened on the bottom surface of the dust box 112, and the side panel 1 110 and the side panel 2 120 are fixedly connected to the dust box 112.

[0039] In this embodiment, the circular hole 612 at one end of the support tube 610 is arranged inside the air duct 500, which will transport part of the hot air inside the air duct 500 to the inside of the support tube 610, and then spray it out from the circular hole 612 on the outside of the support tube 610 and the roller 620 to blow toward the tipping paper, which is convenient for drying the tipping paper and blowing impurities on the surface of the tipping paper toward the dust box 112. At the same time, an external vacuum cleaner is connected to the pipe above the dust box 112, so that the dust box 112 can suck impurities above the tipping paper and outside the brush 630, which can effectively keep the tipping paper to be sprayed with ink clean and tidy to a certain extent.
