[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] like Figure 1-3 As shown, a strapping tape printing device comprises a mounting plate 1, a first adjustment mechanism 2, a second adjustment mechanism 3 and a third adjustment mechanism 4. An ink cartridge 5 with an upward opening, a rotatable ink wheel 6, a printing wheel 71 and a pressure roller 72 are arranged on the front side wall of the mounting plate 1 in order from bottom to top. An ink scraper 73 is arranged adjacent to one side of the printing wheel 71. The pressure roller 72 and the ink scraper 73 can respectively abut against the side wall adjacent to the printing wheel 71. The strapping tape will be sandwiched between the printing wheel 71 and the pressure roller 72. The strapping tape is pressed against the printing wheel 71 by the pressure roller 72. During processing, the strapping tape will slide under the drive of the winding mechanism and drive the printing wheel 71 to rotate. The ink wheel 6 rotates to apply the ink in the ink cartridge 5 to the printing wheel 71, and the excess ink on the printing wheel 71 is scraped off by the ink scraper 73. After that, the remaining ink on the printing wheel 71 will be printed on the corresponding side of the strapping tape, thereby completing the printing of the text symbols on the strapping tape. The first adjustment mechanism 2, the second adjustment mechanism 3 and the third adjustment mechanism 4 are all arranged on the rear side wall of the mounting plate 1. When the user needs to replace the printing wheel 71 with a larger or smaller diameter, the pressure roller 72 can be moved up and down along the surface of the mounting plate 1 through the first adjustment mechanism 2, the ink wheel 6 can be moved up and down along the surface of the mounting plate 1 through the second adjustment mechanism 3, and the scraper plate 73 can be moved left and right along the surface of the mounting plate 1 through the third adjustment mechanism 4, so that the pressure roller 72, the ink wheel 6 and the scraper plate 73 can make adaptive movements according to the size of the printing wheel 71, thereby improving the compatibility and flexibility of the strapping tape printing device for printing wheels 71 of different diameters.

[0028] Specifically, a guide wheel 74 for helping the strapping tape to limit its position and enter between the tape pressing wheel 72 and the printing wheel 71 is also provided on the front side wall of the mounting plate 1 .

[0029] Furthermore, the first adjustment mechanism 2 includes a screw rod 21, a swing rod 22, a first rotating shaft 23 and two upper nuts 24. The upper end of the mounting plate 1 is provided with an avoidance opening 11. The screw rod 21 is vertically arranged on the rear side of the upper end of the mounting plate 1. The two ends of the screw rod 21 are respectively connected to the corresponding positions of the mounting plate 1. The rear end of the swing rod 22 is hinged to the rear side wall of the mounting plate 1. The front end of the swing rod 22 is provided with a waist-shaped opening 221 along its length direction.

The user can swing the swing rod 22 and use the swing rod 22 to drive the first rotating shaft 23 to rise or fall in the avoidance opening 11, so that the belt pressure roller 72 can adapt to the printing wheels 71 of different diameters. When the swing rod 22 swings, the screw rod 21 can slide relatively along the waist-shaped opening 221 to avoid hindering the swing of the swing rod 22. After adjusting the swing rod 22 to a suitable position, it is only necessary to rotate the two upper nuts 24 to clamp the front end of the swing rod 22, and the screw rod 21 can be used to fix the swing rod 22.

[0030] In this embodiment, a fastening screw 222 is threadedly sleeved on the outer wall of the front end of the swing rod 22, and the tip of the fastening screw 222 extends into the waist-shaped opening 221 and abuts against the screw rod 21. The user can tighten the fastening screw 222 to squeeze the screw rod 21 to assist in fixing the swing rod 22.

[0031] Furthermore, an upper mounting ear 12 and a lower mounting ear 13 are sequentially provided along the longitudinal direction on the rear side wall of the mounting plate 1, and a hand wheel 14 is rotatably connected to the upper side wall of the upper mounting ear 12, and the top of the screw rod 21 sequentially penetrates the upper mounting ear 12 and the hand wheel 14, and is threadedly connected to the hand wheel 14, and the bottom end of the screw rod 21 penetrates the lower mounting ear 13, and the bottom end of the screw rod 21 is threadedly screwed with two lower nuts 15, and the two lower nuts 15 can clamp the lower mounting ear 13. When the two upper nuts 24 limit the swing rod 22, the user can also rotate the hand wheel 14, and drive the screw rod 21 to move up or down through the internal thread of the hand wheel 14, and fine-tune the spacing between the pressure wheel 72 and the printing wheel 71, so that the pressure wheel 72 presses the packaging tape on the printing wheel 71. After the fine-tuning is completed, only the two lower nuts 15 need to be rotated to clamp the lower mounting ear 13, so as to limit the up and down movement of the screw rod 21, so that the position of the pressure wheel 72 is completely fixed.

[0032] Furthermore, a sliding hole 223 is provided on the rocker arm 22 along the direction of the hinge axis, and the first rotating shaft 23 is sleeved in the sliding hole 223 and can slide axially along the sliding hole 223, thereby driving the belt pressure wheel 72 to translate axially so as to adapt to the printing wheels 71 of different thicknesses.

The ink wheel 6 is fixedly sleeved on the outer end of the second rotating shaft 34. The second sleeve 31 can slide up and down along the second guide opening 16 to change the distance between the ink wheel 6 and the axis of the printing wheel 71 so that the ink wheel 6 can be adapted to the printing wheels 71 of different diameters. The outer end of the sleeve 31 is provided with a second convex edge 311 along the circumferential direction, and the second convex edge 311 abuts against the front side wall of the mounting plate 1. The second washer 32 and the second threaded sleeve 33 are sequentially sleeved on the outer side of the inner end of the second sleeve 31 in the direction away from the mounting plate 1, and the second threaded sleeve 33 is threadedly connected to the second sleeve 31. The user only needs to rotate the second threaded sleeve 33 to pull the second sleeve 31 inward through the internal thread, so that the second convex edge 311 squeezes the front side wall of the mounting plate 1, and at the same time drives the second washer 32 to be pressed against the mounting plate 1, and utilizes the friction resistance between the two and the mounting plate 1 to limit the sliding of the second sleeve 31, thereby fixing the ink wheel 6.

[0034] Furthermore, the second adjustment mechanism 3 also includes a second screw 35, which is vertically arranged below the second washer 32. The bottom end of the second screw 35 is threadedly connected to the outer wall of the mounting plate 1, and the top end of the second screw 35 abuts against the second washer 32. Rotating the second screw 35 can drive its top end to rise or fall synchronously to adapt to the movement of the second washer 32. The second screw 35 is used to provide additional support force for the second washer 32, thereby improving the installation stability of the ink wheel 6.

[0035] Furthermore, the third adjustment mechanism 4 includes a third sleeve 41, a third gasket 42 and a third threaded sleeve 43.

One end of the scraper plate 73 is connected to the outer end of the third sleeve 41. The third sleeve 41 can slide left and right along the third guide opening 17, thereby changing the distance between the abutting end of the scraper plate 73 and the axis of the printing wheel 71, so that the scraper plate 73 can adapt to printing wheels 71 of different diameters. 1, the outer end of the third sleeve 41 is provided with a third convex edge 411 along the circumferential direction, the third convex edge 411 abuts against the front side wall of the mounting plate 1, the third washer 42 and the third threaded sleeve 43 are sequentially sleeved on the inner end of the third sleeve 41 in the direction away from the mounting plate 1, and the third threaded sleeve 43 is threadedly connected with the third sleeve 41. Similar to the second adjustment mechanism 3, the third threaded sleeve 43 can be rotated to drive the third convex edge 411 and the third washer 42 to be pressed against the mounting plate 1, so as to fix the ink scraper 73.

[0036] Furthermore, the third adjustment mechanism 4 also includes a third rotating shaft 44 and a third screw 45. The third rotating shaft 44 is rotatably sleeved on the inner side of the third sliding sleeve 41. The outer end of the third rotating shaft 44 extends to the front side of the mounting plate 1. One end of the scraper plate 73 is fixedly connected to the outer end of the third rotating shaft 44. The scraper plate 73 can be swung by rotating the third rotating shaft 44, further improving the movable adjustment range of the scraper plate 73, so that the scraper plate 73 can adjust the abutment position when used with printing wheels 71 of different diameters to ensure the ink scraping effect. A lever 46 is radially provided on the inner end of the third rotating shaft 44, and the third screw 45 is vertically arranged on the rear side of the mounting plate 1 and is threadedly connected to the rear side wall of the mounting plate 1. By rotating the third screw 45, the top end of the lever 46 can be used to squeeze the side wall of the lever 46, thereby driving the third rotating shaft 44 to rotate, so that the scraper plate 73 abuts against the side wall of the printing wheel 71, so as to scrape off excess ink on the printing wheel 71.

[0037] Furthermore, the ink cartridge 5 can move up and down along the mounting plate 1. A longitudinal moving opening 18 is provided on the mounting plate 1 in the vertical direction. A transverse through hole 51 is provided on the inner side of the ink cartridge 5 corresponding to the longitudinal moving opening 18.
