Description

Technical Field

[0001] The utility model relates to the field of tattoo pens, in particular to a high-stability tattoo pen driving device. Background Art

[0002] Tattooing is a process of inserting pigment into the skin through a tattoo needle to form a permanent pattern on the skin. In the tattoo process, the most commonly used tool is a tattoo pen. Traditional tattoo pens, similar to the motor tattoo pen publicly accused in ZL202221548977.3, are generally connected to a horizontal motor inside. After the motor drives the eccentric wheel to rotate, the eccentric wheel disk connected to the eccentric wheel through the bearing can drive the ejector pin to reciprocate, thereby driving the needle rod in the pen head to reciprocate, realizing the reciprocating acupuncture operation during the tattoo operation.

[0003] However, in this type of driving device, since the driving shaft of the motor and the eccentric wheel are eccentrically arranged, when the eccentric wheel rotates, the force uniformity of the driving shaft is poor, which easily causes the driving shaft and the eccentric wheel to vibrate and emit noise.

[0004] Therefore, the existing tattoo pen driving device has the problems of large vibration and large noise. Utility Model Content

[0005] The purpose of the utility model is to provide a high-stability tattoo pen driving device. The utility model can not only reduce vibration, but also has the advantage of low noise.

[0006] The technical solution of the utility model is as follows: a high-stability tattoo pen driving device comprises a mounting block, wherein the outer surfaces at both ends of the mounting block are provided with connecting threads for connecting to a tattoo pen housing; a power socket is provided at the top of the mounting block, a vertical sliding cavity is provided inside the bottom of the mounting block, and a driving column for driving the tattoo needle to move is provided in the sliding cavity in cooperation with sliding; a horizontal driving motor is connected to the middle of the mounting block, and a rotating wheel is eccentrically connected to the driving shaft of the driving motor; a counterweight is connected to the side of the rotating wheel corresponding to the eccentric connection with the driving shaft of the driving motor; a sleeve ring is rotatably connected to the rotating wheel through a bearing, a swing rod is connected to the sleeve ring, and a driving rod connected to the driving column is rotatably connected to the end of the swing rod; a guide groove parallel to and connected to the sliding cavity is provided on the mounting block, and the guide groove is slidably matched with the driving rod.

[0007] In the aforementioned high-stability tattoo pen driving device, the counterweight block is arranged in an umbrella shape.

[0008] In the aforementioned high-stability tattoo pen driving device, the driving motor and the rotating wheel are respectively located on both sides of the mounting block.

[0009] In the aforementioned high-stability tattoo pen driving device, the driving rod and the driving shaft of the driving motor are arranged parallel to each other; the driving rod is cylindrical, and a connecting column is provided at the top of the driving rod, and the diameter of the connecting column is smaller than the diameter of the driving rod; the rocker arm is provided with a mounting hole that cooperates with the connecting column, and the driving column is provided with a connecting hole that cooperates with the bottom of the driving rod.

[0010] In the aforementioned high-stability tattoo pen driving device, the collar and the swing rod are integrally arranged.

[0011] Compared with the prior art, the utility model connects a counterweight to a rotating wheel eccentrically connected to a driving motor, and places the counterweight on one side of the rotating wheel eccentrically connected to a driving shaft of the driving motor; when the driving motor drives the rotating wheel and the counterweight to rotate synchronously, the rotating wheel and the counterweight on both sides of the driving shaft of the driving motor balance the force on the driving shaft of the driving motor, thereby reducing vibration during movement and noise. At the same time, when the rotating wheel drives the driving column to reciprocate through the bearing, the collar, the rocker and the driving rod, the driving rod is limited by the guide groove to reciprocate, and the driving column is limited by the sliding cavity to reciprocate. The overall operation stability is high, vibration is not easy to generate, and noise is reduced.

[0012] In addition, the counterweight block in the utility model is arranged in an umbrella shape, which can exert the required centripetal force with a smaller occupied space, has lower cost and better effect.

[0013] The driving motor and the rotating wheel are respectively located on both sides of the mounting block, so that the center of gravity of the mounting block can be maintained in the middle, thereby improving the overall stability and reducing vibration and noise.

[0014] The driving rod is connected to the mounting hole on the rocker arm through a connecting column with a smaller diameter at its top end, and the bottom end of the driving rod is inserted into the connecting hole of the driving column; when the rocker arm drives the driving column to move through the driving rod, the rocker arm can rotate relative to the driving rod and the driving column, and the movement process is smoother and less likely to generate vibration and noise.

[0015] Therefore, the utility model can not only reduce vibration, but also has the advantage of less noise. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0022] Embodiment. A high-stability tattoo pen driving device, comprising: Figures 1 to 4 As shown, it includes a mounting block 1, and the outer surfaces of the upper and lower ends of the mounting block 1 are provided with connecting threads 2 for connecting to the tattoo pen housing; a power socket 3 is provided at the top of the mounting block 1, and a vertical sliding cavity 4 is provided inside the bottom of the mounting block 1, and a driving column 5 for driving the tattoo needle to move is slidably provided in the sliding cavity 4; a horizontal driving motor 6 is connected to the middle of the mounting block 1, and a rotating wheel 7 is eccentrically connected to the driving shaft of the driving motor 6; a counterweight 8 is connected to the rotating wheel 7 at one side corresponding to the eccentric connection with the driving shaft of the driving motor 6; a collar 10 is rotatably connected to the rotating wheel 7 through a bearing 9, and a swing rod 11 is connected to the collar 10, and a driving rod 12 connected to the driving column 5 is rotatably connected to the end of the swing rod 11; a guide groove 13 parallel to and connected to the sliding cavity 4 is provided on the mounting block 1, and the guide groove 13 is slidably matched with the driving rod 12.

[0023] The counterweight block 8 is arranged in an umbrella shape; the driving motor 6 and the rotating wheel 7 are respectively located on both sides of the mounting block 1; the driving rod 12 and the driving shaft of the driving motor 6 are arranged parallel to each other; the driving rod 12 is cylindrical, and a connecting column 14 is provided at the top of the driving rod 12, and the diameter of the connecting column 14 is smaller than the diameter of the driving rod 12; the rocker arm 11 is provided with a mounting hole 15 that cooperates with the connecting column 14, and the driving column 5 is provided with a connecting hole 16 that cooperates with the bottom of the driving rod 12; the collar 10 and the rocker arm 11 are arranged in an integrated manner.

[0024] Working principle: The connecting threads 2 at the upper and lower ends of the mounting block 1 can be used to connect and install the tattoo pen shell, and the two tattoo pen shells can be docked to form a tattoo pen body, and the overall installation is convenient; the bottom of the tattoo pen body can be clamped and installed with a tattoo pen head, so that the top of the needle rod on the tattoo pen head is located in the sliding cavity 4, and the power socket 3 at the top of the tattoo pen body can be connected to a power cord to power the drive motor 6.

[0025] During actual operation, the driving motor 6 fixed on one side of the mounting block 1 drives the rotating wheel 7 and the counterweight 8 located on the other side of the mounting block 1 to rotate synchronously and eccentrically. At this time, the rotating wheel 7 can drive the collar 10 and the swing rod 11 to swing up and down through the bearing 9, and the connecting column 14 rotatably connected to the bottom end of the swing rod 11 through the mounting hole 15 drives the driving rod 12 to slide up and down stably along the guide groove 13; because the bottom of the driving rod 12 is inserted into the connecting hole 16 of the driving column 5, the driving rod 12 can drive the driving column 5 to slide back and forth up and down in the sliding cavity 4 when sliding up and down, thereby realizing the pushing and releasing operation of the needle rod on the tattoo pen head. When the needle rod in the tattoo pen head is pushed, the tattoo needle extends out of the tattoo pen head. When the needle rod in the tattoo pen head is released, the tattoo needle is reset through the reset structure in the tattoo pen head.

[0026] Since the umbrella-shaped counterweight 8 is located on the side of the rotating wheel 7 eccentrically connected to the driving shaft of the driving motor 6, the counterweight 8 balances the uneven mass distribution of the rotating wheel 7 outside the driving shaft of the driving motor 6, so that the driving shaft of the driving motor 6 is subjected to a more uniform force during rotation, can rotate more stably, is not easy to vibrate, and has less noise. At the same time, when the rotating wheel 7 drives the driving column 5 to reciprocate through the bearing 9, the collar 10, the swing rod 11 and the driving rod 12, the driving rod 12 is limited by the guide groove 13 to reciprocate, and the driving column 5 is limited by the sliding cavity 4 to reciprocate. A bearing 9 is provided between the rotating wheel 7 and the collar 10, and the driving rod 12 is rotatably connected to the mounting hole 15 of the swing rod 11 through the top connecting column 14, and the bottom of the driving rod 12 is rotatably connected to the connecting hole 16 of the driving column 5. The overall stability and smoothness during operation are high, and vibration is not easy to occur, thereby reducing noise.
