[0024] An orthodontic nickel-titanium archwire automatic winding machine includes a winding assembly 1 and a turntable 2. The top of the winding assembly 1 is fixedly connected to a pusher 8 via a top frame 7. The output end of the pusher 8 is fixedly connected to a base plate 9. The bottom of the base plate 9 is rotatably connected to a horizontal bar 10 via a bearing 11.

[0025] The orthodontic nickel-titanium arch wire roller is placed on the top of the turntable 2, and the driving part 18 drives the bidirectional screw 19 to rotate. The bidirectional screw 19 is screwed with the two sets of threaded blocks 20 through two sets of opposite threaded grooves on the outer wall. The two sets of threaded blocks 20 move relative to each other and link the corresponding abutment rods 17 until the spacing between the two sets of abutment rods 17 fits the size of the orthodontic nickel-titanium arch wire roller. Then the pushing part 8 pushes the bottom plate 9 downward until the two sets of abutment rods 17 abut against the top of the orthodontic nickel-titanium arch wire roller. Then the turntable 2 drives the orthodontic nickel-titanium arch wire roller to rotate, and when the automatic film winding operation is performed through the film winding assembly 1, the abutment rod 17 will link the horizontal bar 10, and the horizontal bar 10 drives the outer ring 1101 to rotate synchronously with the orthodontic nickel-titanium arch wire roller, so as not to affect the film winding operation. At the same time, the vertical constraint force provided by the abutment rod 17 ensures the stability of the position of the orthodontic nickel-titanium arch wire roller, thereby improving the stability of the orthodontic nickel-titanium arch wire automatic film winding machine.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a liner 3 is fixedly connected to the middle of the top of the turntable 2, a bidirectional motor 14 is fixedly connected to the inner wall of the liner 3, and both output ends of the bidirectional motor 14 are fixedly connected to a transmission rod 16. The outer walls of the two groups of transmission rods 16 are respectively screwed and connected to two groups of moving blocks 15. The outer walls of the two groups of moving blocks 15 are respectively fixedly connected to two groups of limit strips 4. The outer wall of the liner 3 is fixedly connected to a side piece 12. The side piece 12 is fixedly connected to the top of the turntable 2 through a locking rod 13 to ensure that the liner 3 is easy to disassemble and assemble. The liner 3 is fixedly connected to the outer wall of the liner 3 by the cooperation of the side piece 12 and the locking rod 13. In the middle of the top of the turntable 2, according to the diameter of the through hole in the middle of the orthodontic nickel-titanium arch wire roller, the bidirectional motor 14 drives the two sets of transmission rods 16 to rotate, and the two sets of transmission rods 16 are respectively screwed with the two sets of moving blocks 15, and the two sets of moving blocks 15 drive the two sets of limit bars 4 to move relative to each other. When the orthodontic nickel-titanium arch wire roller is placed on the top of the turntable 2, the two sets of limit bars 4 can quickly determine that the orthodontic nickel-titanium arch wire roller is in the middle position, further improving the position stability of the orthodontic nickel-titanium arch wire roller, while allowing the orthodontic nickel-titanium arch wire roller to be quickly aligned with the two sets of abutment rods 17.

[0027] Specifically, such as Figure 2 and Figure 3As shown, the top frame 7 is integrally formed with a strap 5, which is fixedly connected to the top of the membrane assembly 1 through a mounting rod 6, thereby ensuring the convenience of disassembly and assembly of the top frame 7. The bearing 11 includes an outer ring 1101 and an inner ring 1102, and the outer ring 1101 and the inner ring 1102 are fixedly connected to the horizontal bar 10 and the bottom plate 9 respectively, thereby ensuring the vertical position of the horizontal bar 10 without limiting the axial deflection of the horizontal bar 10. The pushing component includes a driving member 18 fixedly connected to the horizontal bar 10, and the driving member 18 outputs The end is fixedly connected with a bidirectional screw 19, and the outer wall of the bidirectional screw 19 is screwed with two groups of thread blocks 20 through two groups of opposite thread grooves. The two groups of thread blocks 20 are respectively fixedly connected with the two groups of abutment rods 17. The driving member 18 drives the bidirectional screw 19 to rotate, and the bidirectional screw 19 is screwed with the two groups of thread blocks 20 through the two groups of opposite thread grooves on the outer wall. The two groups of thread blocks 20 move relative to each other and link the corresponding abutment rods 17 until the spacing between the two groups of abutment rods 17 fits the size of the orthodontic nickel-titanium arch wire roller.

[0028] Working principle: Place the orthodontic nickel-titanium arch wire roller on the top of the turntable 2, and the driving part 18 drives the bidirectional screw 19 to rotate. The bidirectional screw 19 is screwed with the two sets of threaded blocks 20 through two sets of opposite thread grooves on the outer wall. The two sets of threaded blocks 20 move relative to each other and link the corresponding abutment rods 17 until the spacing between the two sets of abutment rods 17 fits the size of the orthodontic nickel-titanium arch wire roller. Then the pushing part 8 pushes the bottom plate 9 downward until the two sets of abutment rods 17 abut against the top of the orthodontic nickel-titanium arch wire roller. Then the turntable 2 drives the orthodontic nickel-titanium arch wire roller to rotate, and when the film winding assembly 1 is used for automatic film winding operation, the abutment rod 17 will link the horizontal bar 10, and the horizontal bar 10 drives the outer ring 1101 to rotate synchronously with the orthodontic nickel-titanium arch wire roller, so as not to affect the film winding operation while passing through the abutment rod 1 The vertical restraining force provided by 7 ensures the stable position of the orthodontic nickel-titanium arch wire roller, thereby improving the stability of the use of the orthodontic nickel-titanium arch wire automatic winding machine. The liner 3 is fixedly connected to the middle of the top of the turntable 2 through the cooperation of the side plate 12 and the locking rod 13. According to the diameter of the through hole in the middle of the orthodontic nickel-titanium arch wire roller, the bidirectional motor 14 drives the two sets of transmission rods 16 to rotate, and the two sets of transmission rods 16 are respectively screwed with the two sets of moving blocks 15.
