Description

Technical Field

[0001] This utility model relates to the field of printhead adjustment technology for digital printing machines, and more specifically, it relates to a printhead adjustment structure for high-definition digital printing machines. Background Technology

[0002] The working principle of a digital printing machine mainly includes image processing, inkjet printing, curing, and post-processing. First, the designed pattern or text is input into the computer software and image processing is performed. Then, the processed image is transmitted to the digital printing machine, where inkjet printing technology is used to spray ink onto the textile.

[0003] Existing digital printing machines typically lay the canvas flat on the surface of the worktable and spray ink vertically downwards through the printhead to apply the desired pattern to the surface of the canvas.

[0004] Vertical downward inkjet printing is only suitable for unprocessed canvas. When printed canvas shoes need to be sprayed, the nozzle cannot adjust the angle to spray ink onto the top of the canvas shoes because the canvas on top of the shoes is at an angle. It is necessary to use wedge blocks to position the canvas shoes at a horizontal angle before inkjet printing. The extra wedge blocks can only be used to position canvas shoes at one angle and also waste costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printhead adjustment structure for a high-definition digital printing machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printhead adjustment structure for a high-definition digital printing machine, comprising a housing, an internal printing mechanism, a third electric slide rail fixedly connected to the inner wall of the housing, a worktable fixedly connected to the sliding end of the third electric slide rail, first electric slide rails respectively provided on both sides of the worktable, the first electric slide rails fixedly connected to the inner wall of the housing and a second electric slide rail fixedly connected to their sliding ends, an ink tank fixedly connected to the sliding end of the second electric slide rail, and a printhead adjustment assembly provided on the lower side of the ink tank.

[0007] The present invention is further configured such that: the printhead adjustment assembly includes a first guide slider fixedly connected to the lower side of the ink tank, a fixing block fixedly connected to each end of the first guide slider, one side of the fixing block fixedly connected to the ink tank, a sliding plate slidably connected to the outer side of the first guide slider, and a first cylinder fixedly connected to one side of the ink tank.

[0008] The present invention is further configured such that: the output end of the first cylinder passes through the ink tank and is fixedly connected to a positioning plate; the other end of the positioning plate is fixedly connected to a slide plate; a second connecting rod is hinged to one side of the slide plate; a first connecting rod is hinged to the other end of the second connecting rod; one end of the first connecting rod is hinged to a first guide slider and the other end is fixedly connected to a printhead; and a stabilizing module is provided on one side of the slide plate.

[0009] The present invention is further configured such that: the stabilizing module includes a card plate fixedly connected to both sides of the slide plate, a second guide slider is fixedly connected to the lower side of the slide plate, and a second cylinder is fixedly connected to the lower side of the second guide slider.

[0010] The present invention is further configured such that: the output end of the second cylinder passes through the second guide slider and is fixedly connected to the slider; two positioning posts are evenly fixedly connected to the upper side of the slider; and the other end of the positioning post passes through the card plate.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] The slide plate moves left and right by extending and retracting the output end of the first cylinder, thereby controlling the oscillation of the print head to adjust the angle. This allows for printing on canvas at different angles on the canvas shoes, eliminating the need to use wedge blocks to place the canvas shoes horizontally. This achieves the effect of adjustable printing angle and material saving. Furthermore, when the print head is printing at an angle, the two positioning pins press against one side of the first guide slider, generating friction to firmly position the print head and effectively prevent the print head from shaking during angled printing.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Please see Figure 1-4 The present invention provides the following technical solution: a printhead adjustment structure for a high-definition digital printing machine, comprising a housing 1, a printing mechanism 2 inside the housing 1, the printing mechanism 2 including a third electric slide rail 26 fixedly connected to the inner wall of the housing 1, a worktable 25 fixedly connected to the sliding end of the third electric slide rail 26, a first electric slide rail 23 respectively provided on both sides of the worktable 25, the first electric slide rail 23 fixedly connected to the inner wall of the housing 1 and a second electric slide rail 24 fixedly connected to the sliding end of the first electric slide rail 23, an ink tank 22 fixedly connected to the sliding end of the second electric slide rail 24, and a printhead adjustment assembly 21 provided on the lower side of the ink tank 22.

[0021] Specifically, the workbench 25 is used to place canvas shoes or canvas that need to be printed. The sliding end of the third electric slide rail 26 is used to control the workbench 25 to move up and down, so that the workpiece is close to the printhead 216. The sliding end of the first electric slide rail 23 is used to control the printhead 216 to move back and forth. The sliding end of the second electric slide rail 24 is used to control the printhead 216 to move left and right. The ink tank 22 is used to supply ink to the printhead 216.

[0022] Please see Figure 3The printhead adjustment assembly 21 includes a first guide slider 212 fixedly connected to the lower side of the ink tank 22. Fixing blocks 211 are fixedly connected to both ends of the first guide slider 212. One side of the fixing block 211 is fixedly connected to the ink tank 22. A sliding plate 219 is slidably connected to the outer side of the first guide slider 212. A first cylinder 213 is fixedly connected to one side of the ink tank 22. The output end of the first cylinder 213 passes through the ink tank 22 and is fixedly connected to a positioning plate 214. The other end of the positioning plate 214 is fixedly connected to the sliding plate 219. A second connecting rod 218 is hinged to one side of the sliding plate 219. A first connecting rod 217 is hinged to the other end of the second connecting rod 218. One end of the first connecting rod 217 is hinged to the first guide slider 212 and the other end is fixedly connected to the printhead 216. A stabilizing module 215 is provided on one side of the sliding plate 219.

[0023] Specifically, the extension and retraction of the output end of the first cylinder 213 is used to control the left and right movement of the skateboard 219. When printing is required on the right side of the canvas of the canvas shoe, the skateboard 219 moves to the left and the nozzle 216 rotates clockwise along one end of the first connecting rod 217. When printing is required on the left side of the canvas shoe, the skateboard 219 moves to the right and the nozzle 216 rotates counterclockwise along one end of the first connecting rod 217, thereby controlling the nozzle 216 to swing and adjust the angle, and thus printing on the canvas at different angles on the top of the canvas shoe.

[0024] Please see Figure 4 The stabilizing module 215 includes a clamping plate 2151 fixedly connected to both sides of the slide plate 219. A second guide slider 2155 is fixedly connected to the lower side of the slide plate 219. A second cylinder 2154 is fixedly connected to the lower side of the second guide slider 2155. The output end of the second cylinder 2154 passes through the second guide slider 2155 and is fixedly connected to a slider 2153. Two positioning posts 2152 are evenly fixedly connected to the upper side of the slider 2153. The other end of the positioning post 2152 passes through the clamping plate 2151.

[0025] Specifically, when the printhead 216 is printing at an angle, it will vibrate and needs to be tightly positioned. Once the angle of the printhead 216 is determined, the output end of the second cylinder 2154 extends and presses the two positioning pins 2152 against one side of the first guide slider 212, thereby generating friction to tightly position the printhead 216, making it difficult for the printhead 216 to slide. When the angle of the printhead 216 needs to be changed, the output end of the second cylinder 2154 retracts. At this time, the two positioning pins 2152 no longer press against one side of the first guide slider 212, and the printhead 216 can slide easily.

[0026] The sliding plate 219 is moved left and right by the extension and retraction control of the output end of the first cylinder 213, thereby controlling the swing of the nozzle 216 to adjust the angle, and thus printing on the canvas at different angles on the canvas shoe. There is no need to use wedge blocks to place the canvas shoe horizontally, which achieves the effect of adjustable printing angle and saving materials. When the nozzle 216 is printing at an angle, the two positioning pins 2152 press against one side of the first guide slider 212, thereby generating friction and firmly positioning the nozzle 216, effectively preventing the nozzle 216 from shaking when printing at an angle.

[0027] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
