[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following reference Figures 1 to 5 This application describes a continuous inkjet printing apparatus for a servo railway freight car provided according to some embodiments.

[0024] Please see Figures 1 to 5 This application provides a continuous inkjet printing device for a servo-type railway freight car, comprising: a trolley 1; a support platform 2 fixed to the upper end of the trolley 1; a support frame 4 fixed to the upper end of the support platform 2; a rectangular frame 5 fixed to the front of the support frame 4; an inkjet printer 6 fixed to the upper end of the support frame 4; a first recessed rail 9 disposed in the middle of the rectangular frame 5; a second recessed rail 13 slidably connected to the first recessed rail 9; a sliding block 14 slidably connected to the second recessed rail 13; an extension plate 15 fixed to the upper end of the sliding block 14; a laser rangefinder 16 fixed to the front of the lower end of the extension plate 15; and an inkjet printhead 17 fixed to the extension plate. The upper front part of 15; laser positioning head 24, located above ink printing head 17; first sliding drive assembly, located in first concave rail 9, used to adjust the left and right spraying position of ink printing head 17; the first sliding drive assembly includes: first forward and reverse motor 11, fixed in the left end of the first concave rail 9; first lead screw 12, one end of which is connected to the power end of the first forward and reverse motor 11, and the other end of the first lead screw 12 is rotatably connected to the right end of the first concave rail 9; the second concave rail 13 is threadedly connected to the first lead screw 12; a spraying pump 7 is connected to the outside of the inkjet printer 6; and a hose 8 is connected between the spraying pump 7 and the ink printing head 17.

[0025] In this embodiment, by setting a first sliding drive component, i.e., the first forward and reverse motor 11 drives the first lead screw 12 to reciprocate, the first lead screw 12 will drive the second concave rail 13 and the ink printing head 17 to move left and right together. With the inkjet printer 6 and the spray pump 7 started, the paint is delivered to the hose 8 and the ink printing head 17. Then, when the ink printing head 17 prints the code on the car body, the left and right movement of the ink printing head 17 makes it easy and convenient to drive the ink printing head 17 to move left and right for spraying.

[0026] In some embodiments, a second sliding drive assembly is disposed within a second recessed rail 13 for adjusting the front and rear spraying distance of the inkjet nozzle 17. The second sliding drive assembly includes: a second forward and reverse motor 18, fixed to the front end of the second recessed rail 13; a second lead screw 19, one end of which is connected to the power end of the second forward and reverse motor 18, and the other end of the second lead screw 19 is rotatably connected to the rear end of the second recessed rail 13. The sliding block 14 is threadedly sleeved with the second lead screw 19.

[0027] In this embodiment, by setting a second sliding drive component, that is, the second forward and reverse motor 18 drives the second lead screw 19 to reciprocate, the second lead screw 19 will drive the sliding block 14 to move back and forth along the second concave rail 13, and at the same time the sliding block 14 will drive the extension plate 15 and the ink printing nozzle 17 to move back and forth, thus facilitating easy and convenient adjustment of the front and rear spraying distance of the ink printing nozzle 17.

[0028] In some embodiments, a height adjustment component is disposed outside the first concave rail 9 and is used to adjust the spraying height of the ink print head 17. The height adjustment component includes: two lifting blocks 10, which are fixed to the left and right ends of the first concave rail 9, and the lifting blocks 10 are slidably sleeved with the rectangular frame 5; a third forward and reverse motor 20, which is fixed to the top inside the rectangular frame 5; and a third lead screw 21, one end of which is connected to the power end of the third forward and reverse motor 20, and the other end of the third lead screw 21 is rotatably connected to the bottom inside the rectangular frame 5, wherein one of the lifting blocks 10 is threadedly sleeved with the third lead screw 21.

[0029] In this embodiment, a height adjustment component is provided, that is, the operation of the third forward and reverse motor 20 drives the third lead screw 21 to reciprocate. The third lead screw 21 drives the lifting block 10 to slide up and down along the rectangular frame 5. The lifting block 10 will drive the first concave rail 9, the second concave rail 14, the extension plate 15 and the ink printing nozzle 17 to move up and down together, thereby facilitating easy and convenient up and down movement of the ink printing nozzle 17 for spraying. In summary, this facilitates easy and convenient spraying of car body codes on railway freight cars, and the spraying process is stable, avoiding the occurrence of accidental deviation of the spraying position due to hand tremors.

[0030] In some embodiments, the laser rangefinder 16 is vertically aligned with the ink printhead 17.

[0031] In this embodiment, as the ink print head 17 moves back and forth, the laser rangefinder 16 also moves back and forth simultaneously. Moreover, the ink print head 17 and the laser rangefinder 16 are vertically aligned. Therefore, the laser rangefinder 16 can accurately measure the distance between the ink print head 17 and the car body, which helps to keep the ink print head 17 at a suitable spraying distance, thereby effectively ensuring the spraying effect.

[0032] In some embodiments, a positioning adjustment component is disposed above the ink print head 17 and is used to adjust the positioning position of the laser positioning head 24. The positioning adjustment component includes: a support plate 22, fixed to the upper end of the ink print head 17; a guide rail plate 23, slidably connected to the front of the support plate 22, wherein the ink print head 17 is fixed to the front of the guide rail plate 23; an adjustment plate 25, fixed to the upper end of the guide rail plate 23; and a threaded adjustment rod 26, rotatably connected to the upper end of the support plate 22, wherein the threaded adjustment rod 26 is threaded through the upper part of the adjustment plate 25.

[0033] In this embodiment, in order to make the ink printing nozzle 17 more accurately aligned with the car body for spraying, the adjusting plate 25, the guide rail plate 23 and the laser positioning head 24 are moved downward by turning the threaded adjusting rod 26. At this time, the guide rail plate 23 will slide along the support plate 22 until the laser positioning head 24 is aligned with the ink printing nozzle 17 and is on the same horizontal line. The light emitted by the laser positioning head 24 is directed to the position to be sprayed on the surface of the car body. Therefore, the light emitted by the laser positioning head 24 is helpful to accurately determine the initial spraying position of the ink printing nozzle 17. After the spraying position is determined, the threaded adjusting rod 26 is turned again to move the adjusting plate 25, the guide rail plate 23 and the laser positioning head 24 upward until the laser positioning head 24 no longer affects the spraying position of the ink printing nozzle 17.
