[0028] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0029] The up and down directions described in the present invention refer to the up and down directions perpendicular to the horizontal plane;

[0030] like Figure 1-2 As shown, the present invention provides a tattoo needle sharpening machine, comprising: a machine body 1, a needle guide plate 2, a needle arrangement unit 3, a pressure plate 4, a guide wheel 5, a rotating wheel 6, a rotating shaft 7, a grinding wheel 8, a support plate 9, and a needle receiving box 12, wherein the machine body 1 comprises a flat plate 101 parallel to a horizontal plane, and an opening 102 is provided on the flat plate 101; the needle guide plate 2 is arranged on the flat plate 101 at an angle to the ground, and the upper surface of the needle guide plate 2 is used to place the tattoo needle to be sharpened. The tattoo needle placed on the needle guide plate 2 has a tendency to roll toward the opening 102 under the action of its own gravity, as shown in FIG. Figure 2As shown, a needle guide bar 201 is provided on one side of the needle guide plate 2. The needle guide bar 201 is higher than the upper surface of the needle guide plate 2 so that one end of the tattoo needle is aligned. A first protrusion 202 is provided on the side of the needle guide plate 2 near the opening 102. The first protrusion 202 extends into a groove 304 near the needle guide plate 2. When the tattoo needle is transferred from the needle guide plate 2 to the needle groove 302 on the needle wheel 301, the first protrusion 202 receives the tattoo needle, making the transfer process smoother and preventing the tattoo needle from falling through the gap between the needle guide plate 2 and the needle wheel 301.

[0031] like Figure 1 As shown, the needle unit 3 is located between the needle guide plate 2 and the opening 102. The needle unit 3 is rotatably arranged on the body 1, and its rotation axis is parallel to the horizontal plane. The needle unit 3 is composed of three needle wheels 301. Figure 5-6 As shown, the outer circumference of the pin wheel 301 is uniformly distributed with needle grooves 302 parallel to the rotation axis of the pin wheel 301, and the side of the pin wheel 301 is provided with a disc-shaped protrusion 303. When three pin wheels 301 are combined side by side to form a pin unit, as shown in FIG. Figure 3-4 As shown, the outer circumferential surface of the protrusion 303 forms the bottom surface of the groove 304, and the part of the side of the pin wheel 301 not covered by the protrusion 303 forms the side of the groove 304, so that the groove 304 is distributed in an annular shape on the outer circumferential surface of the pin wheel 301.

[0032] When forming the needle arrangement unit 3, the relative angles between adjacent needle arrangement wheels 301 can be adjusted so that the needle grooves 302 on the three needle arrangement wheels 301 can be switched between an aligned state and a staggered state. When the diameter of the tattoo needle to be sharpened becomes larger, such as Figure 4 As shown, the needle grooves 302 on the three needle wheels 301 are adjusted to an aligned state so that the large diameter tattoo needle 10 can pass through the adjacent needle grooves 302 and be fixed therein; when the diameter of the tattoo needle to be sharpened becomes smaller, as shown in FIG. Figure 3 As shown, the needle slots 302 on the three needle wheels 301 are adjusted to a staggered state, so that the large-diameter tattoo needles 10 cannot pass through adjacent needle slots 302, and the small-diameter tattoo needles 11 can pass through adjacent needle slots 302 and be fixed therein.

[0033] like Figure 1 As shown, the pressure plate 4 is located above the needle arrangement unit 3. The surface of the pressure plate 4 is an arc surface. The radius of the arc surface of the pressure plate 4 is equal to the radius of the needle arrangement wheel 301. There is a gap between the arc surface of the pressure plate 4 and the outer circumferential surface of the needle arrangement wheel 301. The gap is smaller than the diameter of the tattoo needle. When the needle arrangement unit 3 rotates, the pressure plate 4 can prevent the tattoo needle from being thrown out of the needle groove 302 by the centrifugal force generated by the rotation of the needle arrangement unit 3.

[0034] like Figure 1As shown, the guide wheel 5 is located on one side of the needle arrangement unit 3, and the guide wheel 5 is rotatably arranged on the machine body 1, and the rotation axis of the guide wheel 5 is perpendicular to the horizontal plane, as shown in FIG. Figure 7-8 As shown, the outer circumferential surface of the guide wheel 5 has a V-shaped groove 501 with a flat bottom. When the tattoo needle is transferred from the needle guide plate 2 to the needle arrangement unit 3, the end of the tattoo needle is separated from the needle guide bar 201, which may cause misalignment. The bottom flat surface of the V-shaped groove 501 supports the end of the tattoo needle, so that the end of the tattoo needle can remain flush.

[0035] like Figure 1 As shown, the rotating wheel 6 is located above the opening 102, and the rotating wheel 6 is mounted on the rotating shaft 7 for driving the rotating wheel 6 to rotate. The supporting plate 9 is arranged at the opening and below the rotating wheel 6. The upper surface of the supporting plate 9 matches the outer circumferential surface of the rotating wheel 6. There is a gap between the upper surface of the supporting plate 9 and the outer circumferential surface of the rotating wheel 6 for allowing the tattoo needle to pass through. The supporting plate 9 is provided with a second protrusion, which extends into the groove 304 close to the supporting plate 9. When the tattoo needle is transferred from the needle arrangement unit 3 to the gap between the arc surface of the supporting plate 9 and the outer circumferential surface of the rotating wheel 6, the transfer process is smoother due to the support of the second protrusion, thereby preventing the tattoo needle from falling from the gap between the needle arrangement unit 3 and the supporting plate 9.

[0036] Bearing seats are provided at both ends of the rotating shaft 7, and the bearing seats are provided on the bracket 702. The bearing seats can move up and down in a direction perpendicular to the horizontal plane. A screw is provided on the bracket 702, one end of the screw is connected to the bearing seat, and the other end is connected to the handwheel 701. Rotating the handwheel 701 can drive the rotating wheel 6 to move up and down through the up and down movement of the bearing seat, thereby adjusting the size of the gap between the arc surface of the support plate 9 and the outer circumference of the rotating wheel 6. When the diameter of the tattoo needle becomes larger, the handwheel 701 is rotated to move the rotating wheel 6 upward to increase the above gap. When the diameter of the tattoo needle becomes smaller, the handwheel 701 is rotated to move the rotating wheel 6 downward to reduce the above gap, so as to ensure that the rotating wheel 6 can drive the tattoo needle to move when rotating, and finally the tattoo needle enters the needle receiving box 12. In order to increase the friction between the rotating wheel 6 and the tattoo needle, the rotating wheel 6 is preferably a silicone wheel;

[0037] The grinding wheel 8 is rotatably arranged below the rotating wheel 6, and the rotation axis of the grinding wheel 8 is perpendicular to the rotation axis of the rotating wheel 6. When the rotating wheel 6 rotates to drive the tattoo needle to move, the outer circumferential surface of the grinding wheel 8 contacts the end of the tattoo needle and sharpens it.

[0038] In the above embodiment, no matter the diameter of the tattoo needle becomes larger or smaller, it can be sharpened, thereby achieving the technical effect of sharpening tattoo needles of various diameters.

[0039] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
