[0018] 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.

[0019] Please see Figures 1-4This utility model provides a self-adhesive label paper slitting machine, comprising: a base plate 1, a mounting frame 2 mounted on the top of the base plate 1, an upper shaft 3 and a lower shaft 4 rotatably mounted on one side of the outer wall of the mounting frame 2, two first motors 5 mounted on one side of the outer wall of the mounting frame 2, the output shafts of the two first motors 5 being respectively connected to one end of the upper shaft 3 and the lower shaft 4, a plurality of equally spaced cutters 6 slidably connected to the upper shaft 3, and a plurality of equally spaced support rings 7 slidably connected to the lower shaft 4, and further comprising: a pitch-changing assembly 8 mounted on the top inner wall of the mounting frame 2 and the base plate 1, a plurality of equally spaced connecting assemblies 9 slidably connected to each of the two pitch-changing assemblies 8, and a transmission assembly 10 mounted on one end of the top outer wall of the base plate 1, a first annular groove 11 being formed on one side of the outer wall of the cutter 6, and a second annular groove 12 being formed on one side of the outer wall of the support ring 7.

[0020] It should be noted that the two first motors 5 can drive the upper shaft 3 and the lower shaft 4 to rotate respectively. The sheet material is cut between the cutter 6 and the support ring 7. When it is necessary to adjust the cutting width and the distance between the cutters 6, the transmission component 10 can drive the two pitch-changing components 8 to rotate at the same time, thereby adjusting the distance between the connecting components 9, and thus the distance between the cutters 6. At the same time, the distance between the support rings 7 is also adjusted to facilitate the adaptation of the cutters 6 after the distance is adjusted. The first annular groove 11 and the second annular groove 12 ensure that the connecting component 9 does not affect the rotation of the cutters 6 and the support ring 7.

[0021] In a preferred embodiment, the pitch-changing assembly 8 includes a mounting frame 801, a pitch-changing screw 802 rotatably mounted on one side of the outer wall of the mounting frame 801, and a driven bevel gear 803 mounted on one end of the mounting frame 801.

[0022] It should be noted that the transmission assembly 10 can drive the driven bevel gear 803 to rotate, which in turn drives the variable pitch screw 802 to rotate.

[0023] In a preferred embodiment, the connecting assembly 9 includes a slider 901, a fixing rod 902 mounted on the top of the slider 901, a connecting plate 903 mounted on the bottom of the slider 901, and a limiting wheel 904 mounted on the outer wall of one side of the connecting plate 903; the first annular groove 11 and the second annular groove 12 have the same structure, and the multiple limiting wheels 904 are respectively placed in the corresponding first annular groove 11 and the second annular groove 12.

[0024] It should be noted that the rotation of the variable pitch screw 802 can drive the fixed rod 902 and the slider 901 to move, which in turn drives the corresponding cutter 6 or support ring 7 to move through the connecting plate 903 and the limit wheel 904, thereby adjusting the distance between the cutter 6 and the distance between the support ring 7.

[0025] In a preferred embodiment, the transmission assembly 10 includes a second motor 1001, a rotating shaft 1002 mounted on the top of the output shaft of the second motor 1001, and driving bevel gears 1003 mounted on both ends of the rotating shaft 1002; the two driving bevel gears 1003 respectively mesh with two driven bevel gears 803.

[0026] It should be noted here that the second motor 1001 can drive the rotating shaft 1002 to rotate, which in turn drives the two active bevel gears 1003 to rotate, which in turn drives the two driven bevel gears 803 to rotate.

[0027] Working principle: The two first motors 5 can drive the upper shaft 3 and the lower shaft 4 to rotate respectively. The sheet is cut between the cutter 6 and the support ring 7. When it is necessary to adjust the cutting width or the distance between the cutters 6, the second motor 1001 can drive the rotating shaft 1002 to rotate, which in turn drives the two active bevel gears 1003 to rotate, which in turn drives the two driven bevel gears 803 to rotate, which in turn drives the two variable pitch screws 802 to rotate.

[0028] The rotation of the variable pitch screw 802 can drive the fixed rod 902 and the slider 901 to move, which in turn drives the corresponding cutter 6 or support ring 7 to move through the connecting plate 903 and the limiting wheel 904, adjusting the distance between the cutter 6 and the distance between the support ring 7, so as to facilitate the adaptation of the cutter 6 after the distance is adjusted. The first annular groove 11 and the second annular groove 12 are provided so that the limiting wheel 904 does not affect the rotation of the cutter 6 and the support ring 7.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
