Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0046] like Figures 1-5 As shown in the figure, this embodiment proposes a drawing device for constantan alloy thermocouple wire, including a drawing machine body 1, which is a tower wheel type drawing machine. A support frame 2 is installed on the drawing machine body 1, and it also includes a support base 3, a support column 4, a take-up drum 6, a positioning mechanism, and a rotating mechanism.

[0047] Reference Figures 2-4 The positioning mechanism includes a first cavity 7, a positioning disc 9, a positioning block 10, a fixing groove 11, a first moving mechanism, and a second moving mechanism. The first cavity 7 is located inside the support column 4. Multiple positioning through holes 8 are provided on the side wall of the first cavity 7. The positioning disc 9 is slidably disposed along the axial direction of the support column 4. A positioning groove is provided on the side wall of the positioning disc 9. The positioning block 10 is slidably disposed in the positioning groove. Multiple fixing grooves 11 are provided on the side wall of the take-up drum 6. The fixing grooves 11 are connected to the inner wall of the take-up drum 6. The fixing grooves 11 are adapted to the shape of the positioning block 10. The first moving mechanism is located inside the first cavity 7 and is used to drive the positioning disc 9 to move within the first cavity 7. The second moving mechanism is located inside the positioning groove and is used to drive the positioning block 10 to move within the positioning groove. Specifically, the operation of the second moving mechanism can drive the positioning block 10 to move, so that the positioning block 10 can extend out of the support column 4 through the positioning through holes 8, thereby facilitating the installation and disassembly of the take-up drum 6 through the cooperation of the positioning block 10 and the positioning ring 5.

[0048] Reference Figures 2-5The second moving mechanism includes a first threaded rod 12, a second cavity, a second bevel gear 14, a third cavity, a first gear ring 16, and a drive mechanism. The first threaded rod 12 is rotatably disposed at the bottom of the positioning groove and extends into the positioning block 10 through a threaded engagement. The positioning disk 9 has a second cavity on one side of the positioning groove. A first bevel gear 13 is rotatably disposed on the side wall of the second cavity near the first threaded rod 12. The first bevel gear 13 is fixedly connected to the first threaded rod 12. The second bevel gear 14 is rotatably disposed on the inner top wall of the second cavity. The second bevel gear 14 is connected to the first threaded rod 12. The bevel gear 13 meshes with the positioning disk 9, which has an annular third cavity on one side of the second cavity. A first gear 15 is rotatably mounted in the third cavity on one side of the second bevel gear 14. A drive column is fixed between the first gear 15 and the second bevel gear 14. A first gear ring 16 is rotatably mounted in the third cavity and meshes with the first gear 15. A drive mechanism is mounted on the support column 4 to drive the first gear 15 to rotate. The drive mechanism includes a first drive port 17, a second drive port 18, a drive prism 19, and a first handwheel 20. The first drive port 17... A first drive port 17 is formed on one of the first gears 15, passing through the adjacent drive column and the second bevel gear 14. A second drive port 18 is formed on the positioning plate 9, aligned with the first drive port 17. A drive prism 19 is rotatably disposed within the first cavity 7, passing through the first drive port 17 and the second drive port 18, and is slidably connected to the side wall of the first drive port 17. A first handwheel 20 is rotatably disposed on the support column 4, and is fixedly connected to the drive prism 19. Specifically, the rotation of the first handwheel 20 can drive the drive... The moving prism 19 rotates, and the sliding engagement between the driving prism 19 and the first driving port 17 drives the first gear 15 to rotate. Simultaneously, the meshing of the first gear 15 with the first gear ring 16 drives multiple first gears 15 to rotate, which in turn drives multiple second bevel gears 14 to rotate through the transmission of the driving column. At the same time, the meshing of the first bevel gear 13 with the second bevel gear 14 drives the first threaded rod 12 to rotate. Thus, the threaded engagement between the first threaded rod 12 and the positioning block 10 drives the positioning block 10 to extend through the positioning through hole 8 and out of the support column 4.

[0049] Reference Figures 3-4The first moving mechanism includes a second threaded rod 21 and a second handwheel 22. The second threaded rod 21 is rotatably disposed in the first cavity 7 and passes through the positioning disk 9 through a threaded engagement. The second handwheel 22 is rotatably disposed on the support column 4 and is fixedly connected to the second threaded rod 21. Specifically, the rotation of the second handwheel 22 can drive the second threaded rod 21 to rotate. At the same time, the threaded engagement between the second threaded rod 21 and the positioning disk 9 drives the positioning disk 9 and the positioning block 10 to move, thereby driving the positioning block 10 to extend into the fixing groove 11 and cooperate with the positioning ring 5 to stably clamp the winding drum 6, thereby improving the installation stability of the winding drum 6.

[0050] Reference Figure 1 and Figure 2 The rotating mechanism includes a second gear ring 23, a second gear 24, and a motor. The second gear ring 23 is fixedly mounted on the support column 4, and the second gear 24 is rotatably mounted on the support base 3. The second gear 24 meshes with the second gear ring 23. The motor is mounted on the support base 3, and the output end of the motor is fixedly connected to the second gear 24. Specifically, the operation of the motor can drive the second gear 24 to rotate. At the same time, the meshing of the second gear 24 with the second gear ring 23 drives the support column 4 and the winding drum 6 to rotate, thereby facilitating the winding of the constantan alloy thermocouple wire.

[0051] In this embodiment, during use, after the operator mounts the take-up drum 6 onto the support column 4, the operator rotates the first handwheel 20. The rotation of the first handwheel 20 drives the drive prism 19 to rotate, and simultaneously, through the sliding engagement between the drive prism 19 and the first drive port 17, it drives the first gear 15 to rotate. Simultaneously, through the meshing of the first gear 15 and the first gear ring 16, multiple first gears 15 rotate, which in turn, through the transmission of the drive column, drive multiple second bevel gears 14 to rotate. Simultaneously, through the meshing of the first bevel gear 13 and the second bevel gear 14, the first threaded rod 12 rotates. Thus, through the threaded engagement between the first threaded rod 12 and the positioning block 10, the positioning block 10 extends through the positioning through hole 8 and out of the support. After the column 4 is in operation, the operator rotates the second handwheel 22. The rotation of the second handwheel 22 can drive the second threaded rod 21 to rotate. At the same time, through the threaded engagement of the second threaded rod 21 with the positioning plate 9, the positioning plate 9 and the positioning block 10 are moved. This allows the positioning block 10 to extend into the fixing groove 11 and cooperate with the positioning ring 5 to stably clamp the winding drum 6, thereby improving the installation stability of the winding drum 6. Then, during the operation of the wire drawing machine body 1, after the wire is wound around the winding drum 6, the motor is controlled to work. The operation of the motor can drive the second gear 24 to rotate. At the same time, through the meshing of the second gear 24 with the second gear ring 23, the support column 4 and the winding drum 6 are driven to rotate, thereby winding the constantan alloy thermocouple wire.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
