[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-6 As shown, a guide wire device includes: Installation platform; The telescopic part is mounted on the mounting platform. The telescopic part can rotate on the mounting platform. The extension length of the telescopic part can be adjusted. The telescopic part is used to guide the wire 1. The drive unit is mounted on the mounting platform and is used to control the reciprocating swing of the telescopic unit on the mounting platform. The limiting part is set on the mounting platform and is used to limit the extension length of the telescopic part.

[0019] Furthermore, the mounting platform includes two support plates 2, which are connected by a fixing plate 3. The upper surfaces of both ends of the support plates 2 are respectively provided with upright plates 4, and the upper surfaces of the support plates 2 are provided with grooves.

[0020] The blank area of ​​the groove on the support plate 2 has a convex shape in cross section.

[0021] Furthermore, the telescopic part includes two sleeves 5, which are connected by a crossbar 6. A column 7 is provided on the upper surface of the crossbar 6. The column 7 passes through the fixing plate 3 and is rotatably connected to the fixing plate 3. An annular retaining ring 8 is provided at one end of each of the two sleeves 5. A round rod 9 is slidably connected inside the two sleeves 5. The two round rods 9 are connected by a baffle 10. A spring 11 is sleeved on the round rod 9. The spring 11 is located between the retaining ring 8 and the baffle 10. A side plate 28 is provided on the baffle 10. A top rod 12 is provided on the side plate 28. A roller 13 is provided on the top rod 12. The roller 13 is rotatably connected to the top rod 12. A top ring 14 is rotatably connected to the upper end of the top rod 12. A guide wire hole is provided on the top ring 14.

[0022] Sleeve 5 is a metal tube, and crossbar 6 is a metal rod. Both are made of the same material. Sleeve 5 and crossbar 6 are connected together by welding. Column 7 and fixed plate 3 are connected by bearings to reduce the friction between column 7 and fixed plate 3 when column 7 rotates.

[0023] The round rod 9 is a metal rod. A cylindrical plastic sleeve can be set on the surface of the round rod 9 to reduce the weight of the round rod 9, but at the same time to give the round rod 9 a certain rigidity and prevent the round rod 9 from bending.

[0024] The spring 11 should be selected with appropriate strength. The spring 11 is always in a compressed state. The spring 11 can always push the round rod 9 out of the sleeve 5 through the baffle 10. When the spring 11 needs to be compressed, the required squeezing force is also low, so as to save effort and reduce the friction between the roller 13 and the limiting part.

[0025] A counterweight can be installed inside the sleeve 5 at the end furthest from the retaining ring 8 to balance the weight distribution below the column 7.

[0026] The push rod 12 is a metal tube, and the roller 13 is mounted on the outside of the push rod 12 through a bearing. The surface of the roller 13 can always be in contact with the limiting part, so that the round rod 9 can be pushed into the sleeve 5, or the round rod 9 can be pushed out of the sleeve 5 by the spring 11.

[0027] The roller 13 is made of nylon plastic.

[0028] Furthermore, the drive unit includes a reciprocating screw 15 and a guide rod 16 disposed between the two upright plates 4. One side of one of the upright plates 4 is provided with a motor 17 for driving the reciprocating screw 15 to rotate. A slide block 18 is provided on the reciprocating screw 15. A gear 19 is provided at the upper end of the column 7. The unit also includes a rack 20 that meshes with the gear 19. The rack 20 and the slide block 18 are connected by an intermediate plate 21. Two sliding sleeves 22 are provided on one side of the rack 20. The sliding sleeves 22 are slidably connected to the guide rod 16.

[0029] By starting the motor 17, the reciprocating screw 15 can be driven to rotate. Since the slide 18 is connected to the rack 20 through the intermediate plate 21, and the rack 20 is slidably connected to the guide rod 16 through the sliding sleeve 22, the slide 18 can reciprocate linearly on the threaded section of the reciprocating screw 15 without changing the rotation direction of the output end of the motor 17 through the cooperation of the reciprocating screw 15 and the slide 18.

[0030] When the slide block 18 moves in a reciprocating linear motion, it will drive the rack 20 to move. When the rack 20 moves, it can drive the column 7 to rotate by meshing with the gear 19, which in turn drives the crossbar 6, sleeve 5, round rod 9 below to rotate, and causes the top ring 14 on the top rod 12 to swing back and forth.

[0031] When the slide block 18 is in the middle position of the reciprocating screw 15, the gear 19 meshes with the middle teeth of the rack 20. When the gear 19 meshes with the two ends of the rack 20, the gear 19 needs to rotate by 60° clockwise and 60° counterclockwise.

[0032] The motor 17 is controlled by a controller, and parameters such as the speed of the motor 17 can be adjusted.

[0033] When the rack 20 meshes with the gear 19, the rack 20 and the gear 19 can maintain a stable meshing state through the cooperation of the intermediate plate 21, the sliding sleeve 22 and the polished rod 16.

[0034] Furthermore, the limiting part includes a limiting plate 23, a reinforcing plate 24 is provided on the lower surface of the limiting plate 23, and through holes are respectively opened at both ends of the limiting plate 23. It also includes bolts 25 and nuts 26. The bolts 25 are located inside the groove, and the limiting plate 23 is fixed to the support plate 2 through the nuts 26 and the through holes.

[0035] Once the position of the limiting plate 23 on the support plate 2 is determined, the limiting plate 23 can be fixed to the support plate 2 by connecting the nut 26 and the bolt 25. The two ends of the limiting plate 23 should be installed in the same position on the two support plates 2 as much as possible.

[0036] When the external winding mechanism winds up the wire 1, one end of the wire 1 is first passed through the top ring 14, and then the wire 1 is fixed to the spool 27 used for winding the wire 1. Next, the winding mechanism drives the spool 27 to rotate, and the spool 27 begins to wind up the wire 1. During this process, the motor 17 is started, which drives the two sleeves 5 to swing and causes the roller 13 to move along the side of the limiting plate 23. During the movement of the roller 13 along the side of the limiting plate 23, if the roller 13 moves closer to the support plate 2... When moving in a direction, the spring 11 pushes the baffle 10 to move, causing the round rod 9 to extend outward from the sleeve 5 by a certain length, thereby allowing the roller 13 to move along the side of the limiting plate 23. When the roller 13 moves towards the center of the limiting plate 23, the limiting plate 23 applies pressure to the roller 13, allowing the round rod 9 to extend into the sleeve 5 by a certain length. In this way, it can be ensured that the top ring 14 is always located on one side of the limiting plate 23, and that the distance between the top ring 14 and the limiting plate 23 remains approximately the same.

[0037] The installation position of the limiting plate 23 on the support plate 2 is adjusted according to the length of the spool 27 used for winding the yarn 1, thereby adjusting the moving distance of the top ring 14. The farther the limiting plate 23 is from the fixed plate 3, the longer the moving distance of the top ring 14, and vice versa. However, there are upper and lower limits to the distance between the limiting plate 23 and the fixed plate 3. It is necessary to ensure that the roller 13 can always contact the side of the limiting plate 23, and the compression of the spring 11 should not be too excessive to avoid excessive friction between the roller 13 and the limiting plate 23.

[0038] Since the top ring 14 can rotate on the top rod 12, no matter how the top ring 14 moves, it can effectively prevent the top ring 14 from rubbing against the wire 1 under normal working conditions, thus preventing damage to the wire 1.

[0039] In this application, whenever two parts are involved in a rotating fit, the two parts are connected by bearings.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
