Description

Technical Field

[0001] The utility model relates to the technical field of texturing machines, in particular to a wire guiding mechanism of a texturing machine. Background Art

[0002] The texturing machine is a kind of mechanical equipment commonly used in the textile industry. It mainly processes untwisted yarns such as polyester and polypropylene into elastic stretch yarns through false twisting. The wire guide device in the texturing machine is mainly used to guide the movement of the yarn.

[0003] Common wire guide devices include a mounting plate and a wire guide wheel. The mounting plate is mounted on the texturing machine to support the wire guide wheel. The wire guide wheel is rotatably mounted on one side of the mounting plate, and an L-shaped groove is fixedly connected to the side of the wire guide wheel. When the texturing machine is working, the wire is located in the L-shaped groove, and the wire passes around the wire guide wheel to guide the wire.

[0004] When the guide wheel is conveying the filaments, the filaments will be overly taut and the tension will increase. The filaments will easily be stretched or even broken under the action of their own tension. The broken filaments will not be conveyed forward, but will be entangled on the rotating guide wheel in circles. At this time, the guide wheel needs to be stopped manually and the silk thread needs to be re-combed. Therefore, workers need to come over from time to time to prevent problems from occurring. If they are not discovered in time, the filaments will be rolled up too much and will not be easy to remove, thus causing difficulties in production. Utility Model Content

[0005] The utility model aims to provide a wire guiding mechanism for a texturing machine, which has the advantage that when a filament is broken, it can be wound up by a wire guiding wheel and stop in time.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A wire guide mechanism for a texturing machine comprises a mounting plate, an active wire guide wheel, a driven wire guide wheel, a switch, a limiting mechanism and a driving mechanism, wherein the driving mechanism comprises a motor and a switch, wherein the motor is fixedly connected to the bottom of the mounting plate, the switch is located on the surface of the mounting plate, the switch is rotatably connected to the mounting plate, the switch is electrically connected to the motor, the active wire guide wheel is located on the surface of the mounting plate, close to the switch, and is rotatably connected to the mounting plate, the active wire guide wheel is fixedly connected to the motor, the driven wire guide wheel is rotatably connected to the mounting plate close to the active wire guide wheel, the limiting mechanism comprises two limiting grooves, including one limiting groove and two limiting grooves, wherein the one limiting groove is located on the side between the two wire guide wheels and is fixedly connected to the mounting plate, the two limiting grooves are away from the active wire guide wheel and are fixedly connected to the mounting plate, the filament first passes through the second limiting groove, and passes through the first limiting groove when bypassing the two wire guide wheels, the limiting groove fixes the movement of the filament to prevent the filament from detaching from the wire guide wheel and causing wire jump, the active wire guide wheel drives the filament wound thereon to bypass the driven wire guide wheel and be forwardly transported, and the switch controls the start and shut down of the motor.

[0008] By adopting the above technical solution, when the filament breaks, it will not continue to be transported forward. The rotation of the active guide wheel will wrap it around in circles, and the radius of the guide wheel will become larger, thereby touching the switch, turning it, shutting down the motor, and stopping the rotation of the active guide wheel. The filament will no longer be entangled, thus avoiding untimely manual inspection, which will cause excessive entanglement of the filament on the guide wheel, causing difficulties in production.

[0009] Preferably, the driven wire guide wheel includes a rotating wheel and a base. The rotating wheel is located on the upper part of the base and is rotatably connected to the base. The lower part of the base is fixedly connected with bolts. A groove is opened inside the mounting plate, and there are threads around the groove. The bolt is located in the groove and is threadedly connected to the mounting plate.

[0010] By adopting the above technical solution, when the driven wire guide wheel is damaged, the driven wire guide wheel can be removed by screwing the base bolts for replacement.

[0011] Preferably, the active guide wire wheel is evenly divided into four sector-shaped bodies and a central axis, the central axis is located at the center of the four sector-shaped bodies, there is a gap between each sector, and the sector-shaped body and the central axis are fixedly connected by an elastic telescopic rod.

[0012] By adopting the above technical solution, when the filament is too tight, the tension becomes greater, and the coil wrapped around the active wire guide wheel will shrink and tighten the active wire guide wheel. The active wire guide wheel shrinks and the coil becomes loose, which is used to buffer the tension and prevent the filament from breaking.

[0013] Preferably, the elastic telescopic rod includes a rod body, a rod sleeve sleeved outside the rod body, and a spring, one end of the rod body is fixedly connected to the inner wall of the fan-shaped body, the end of the rod sleeve away from the rod body is fixedly connected to the central axis, the spring is located in the rod sleeve, one end of the spring is fixedly connected to the rod sleeve, the other end of the spring is fixedly connected to the rod body, and the rod body moves in the rod sleeve.

[0014] When the filament is too tight, the tension increases, pushing the fan-shaped body close to the center axis, so that the fan-shaped body pushes the rod body to move inside the rod sleeve. The movement of the rod body compresses the spring, the active wire guide wheel contracts, the coil becomes loose and the tension decreases.

[0015] Preferably, the driven wire guide wheel includes a rotating wheel, a base, and a connecting device, the connecting device includes a telescopic rod and a spring, the telescopic rod is located inside a groove on the surface of a mounting plate, one end of the telescopic rod is hinged to the bottom of the groove, the spring is sleeved on the telescopic rod, one end of the spring is fixedly connected to the bottom of the groove, the base is located on the surface of the mounting plate and is slidingly connected to the mounting plate, the other end of the telescopic rod is hinged to the bottom of the base, the other end of the spring is fixedly connected to the bottom of the base, the rotating wheel is located on the upper part of the base and is rotatably connected to the base.

[0016] With the above technical solution, when the filaments are too tight, the tension increases, which pulls the guide wheel to move, and the spring relieves the tension to prevent the filaments from breaking. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting groove 61 is located at the side between the active guide wheel 4 and the driven guide wheel 5, and is fixedly connected to the mounting plate 1. The limiting groove 62 is located at the lower part of the mounting plate 1 and is fixedly connected to the mounting plate 1. The filament first passes through the limiting groove 62, and then passes through the limiting groove 61 when bypassing the driven guide wheel 5 and the active guide wheel 4. The limiting groove limits the movement of the filament to prevent it from jumping. The rotating active guide wheel 4 drives the filament wound thereon to bypass the driven guide wheel 5 and be transported forward. When the filament breaks, it will no longer continue to be transported forward. The rotation of the active guide wheel 4 will wrap it around it in circles, and the radius of the active guide wheel 4 will become larger, thereby touching the switch 3, turning it, turning off the motor 2, and the active guide wheel 4 stops rotating, and the filament is no longer entangled.

[0024] See also Figure 3 The active guide wheel 4 is evenly divided into four sector-shaped bodies 41 and a central axis 42. The central axis 42 is located at the center of the four sector-shaped bodies 41, and there is a gap between each sector.

The four sector-shaped bodies 41 squeeze the telescopic rod inward, the telescopic rod retracts, and the active guide wheel 4 shrinks to buffer the tension and prevent the filament from breaking.

[0025] See also Figure 4 The driven wire guide wheel 5 includes a rotating wheel 51 and a base 52. The rotating wheel 51 is located on the upper part of the base 52 and is rotatably connected to the base 52. The lower part of the base 52 is fixedly connected with a bolt 54.

[0026] Working principle: the filament first passes through the limiting groove 62, and then passes through the limiting groove 61 when bypassing the driven wire guide wheel 5 and the active wire guide wheel 4. The limiting groove limits the movement of the filament to prevent it from jumping. The rotating active wire guide wheel 4 drives the filament wound thereon to bypass the driven wire guide wheel 5 and transport it forward. When the filament is too tight, the tension becomes large, and the coil wound on the active wire guide wheel 4 will shrink and tighten the active wire guide wheel 4.

When another driven wire guide wheel is used, the bolt 54 of the base 52 can be turned to remove the driven wire guide wheel 5 from the mounting plate for replacement.
