Description

Technical Field

[0001] This utility model belongs to the technical field of nail art printing equipment, and specifically relates to a nail art printer. Background Technology

[0002] Nail printers are devices that can draw patterns on natural and artificial nails. With the popularization of nail art, nail printers have become the best alternative to street nail technicians. However, existing nail printers have the following shortcomings during use: the ink cartridge control method can cause jamming, which can lead to uneven color in the printed pattern and affect the quality of the nail art. Summary of the Invention

[0003] The purpose of this invention is to provide a nail printer to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A nail printer includes a chassis, a mounting bracket, a printing component, and a positioning component. The mounting bracket is fixedly provided at the bottom of the chassis, and an opening is provided on the side wall of the chassis for inserting a hand into the mounting bracket. The printing component is located above the mounting bracket, and the positioning component is fixedly connected to the top of the chassis.

[0006] The fixed bracket includes a limiting frame, a finger support, a base, a limiting fixing block, a support shell, a conversion block I, a support plate, a conversion block II, a rotating shaft, a retaining shaft, a retaining block, and a spring. The base is fixedly connected to the bottom of the chassis. The limiting frame is fixedly installed on the top of the base. The support shell is slidably connected inside the limiting frame. The finger support is fixedly installed on the top of the support shell. The conversion block I is fixedly installed inside the support shell. The support plate is fixedly installed at the bottom of the support shell. The conversion block II is fixedly installed on the top of the support plate. A through hole is opened at the center of the support plate and the conversion block II. The rotating shaft is slidably connected in the through hole of the support plate and the conversion block II. A retaining shaft is provided on the top side wall of the rotating shaft. A retaining block is fixedly installed at the bottom of the rotating shaft. A ball bearing is provided at the bottom of the retaining block. Two limiting fixing blocks are fixedly installed inside the base. The two limiting fixing blocks are placed symmetrically. The limiting fixing blocks are in the shape of a "7" and fixed to the bottom of the chassis. A spring is provided between the limiting fixing blocks and the support plate.

[0007] During use, by placing a finger on the finger holder, pressing the finger down causes the support shell and support plate to compress the spring and move downwards. When the locking block touches the bottom, the rotating shaft causes the locking shaft to move upwards relative to the support plate. Then, under the action of conversion block I and conversion block II, the locking shaft causes the rotating shaft and the locking block to rotate 90°. After releasing the finger, under the action of the spring, the support plate causes the support shell to move upwards until the locking block is locked into the limiting fixing block. At this time, the finger can be limited and fixed by the limiting frame.

[0008] The printing assembly includes a motor base, a motor I, a screw I, an optical axis I, an ink cartridge, and a clamping block. The motor base is fixedly connected to the inner side wall of the chassis. The motor I is fixedly connected to the motor base. The output end of the motor I is connected to the screw I via a coupling. The screw I passes through the clamping block, and the clamping block has threads inside that mate with the screw I. The ink cartridge is snapped onto the clamping block. An optical axis I is located above the screw I. One end of the optical axis I passes through the clamping block and is fixedly connected to the motor base, while the other end is fixedly connected to the side wall of the chassis.

[0009] After the finger is positioned and fixed, the motor I provides power to drive the screw I to rotate. The rotation of the screw I then drives the clamping block to move the ink cartridge under the support of the optical axis I.

[0010] Preferably, the positioning component includes a motor II, a screw II, an optical axis II, a nut block, a base, a linear laser, a camera, and a fill light. The motor II is fixedly connected to the top of the chassis via a bracket. The output end of the motor II is connected to the screw II via a coupling. The screw II passes through the nut block and is threadedly connected to the nut block. The bottom of the nut block is fixedly connected to the base. The linear laser is installed inside the base. The end of the base is provided with the optical axis II. Both ends of the optical axis II are fixedly connected to the top of the chassis via brackets. The camera is installed on the top of the chassis via a mounting base. A fill light is fixedly installed on one side of the camera.

[0011] During the positioning process, a supplementary light provides sufficient light to the camera, the camera determines the finger position, and the acquired position signal is transmitted back to the computer. Motor II provides power to drive screw II to rotate, and the rotation of screw II drives the nut block to move the base. The movement of the base drives the linear laser to complete the scanning of the fingernail shape.

[0012] Preferably, the side wall of the chassis is provided with heat dissipation holes to allow heat inside the chassis to be quickly dissipated.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] By attaching the ink cartridge to the clamping block, and then driving the clamping block by rotating the screw I, the optical axis I, which is parallel to the screw I and located above the clamping block, can limit the clamping block's forward and backward movement. The screw I only plays an auxiliary sliding role in the direction of movement, thus preventing jamming during the driving of the clamping block. With the clamping block moving smoothly, the printing process of the ink cartridge can be made smoother, preventing jamming and improving the print quality of the ink cartridge.

[0025] The printing assembly 3 includes a motor base 30, a motor I 31, a screw I 32, an optical axis I 33, an ink cartridge 34, and a clamping block 35. The motor base 30 is fixedly connected to the inner side wall of the housing 1. The motor I 31 is fixedly connected to the motor base 30. The output end of the motor I 31 is connected to the screw I 32 via a coupling. The screw I 32 passes through the clamping block 35. The clamping block 35 has threads inside that mate with the screw I 32. The ink cartridge 34 is snapped onto the clamping block 35. An optical axis I 33 is located above the screw I 32. One end of the optical axis I 33 passes through the clamping block 35 and is fixedly connected to the motor base 30, while the other end is fixedly connected to the side wall of the housing 1.

[0026] The positioning component 4 includes a motor II 41, a screw II 42, an optical axis II 43, a nut block 44, a base 45, a linear laser 46, a camera 47, and a fill light 48.

When the locking block 28 touches the bottom, the rotating shaft 27 causes the locking shaft 271 to move upward relative to the support plate 26. Then, under the action of the conversion block I 251 and conversion block II 261, the locking shaft 271 causes the rotating shaft 27 and the locking block 28 to rotate 90°. After the finger is released, under the action of the spring 29, the support plate 26 causes the support shell 25 to move upward until the locking block 28 is locked into the limiting fixing block 24.

The camera 47 determines the finger position and transmits the acquired position signal back to the computer. The motor II 41 provides power to drive the screw II 42 to rotate. The rotation of the screw II 42 drives the nut block 44 to move the base 45. The movement of the base 45 drives the linear laser 46 to complete the scanning of the fingernail shape.

[0029] After the finger is positioned and fixed, the motor I31 provides power to drive the screw I32 to rotate. The rotation of the screw I32 then drives the clamping block 35 to move the ink cartridge 34 under the support of the optical axis I33, thus completing the nail art pattern.
