Description

Technical Field

[0001] This utility model relates to the field of fabric production, and in particular to a yarn anti-tangling guide device for a ribbon weaving machine. Background Technology

[0002] In the textile industry, ribbon looms are key equipment for producing various ribbon products, and the yarn feeding process plays a crucial role in ribbon quality. With the diversification of textile processes and the increasing market demand for ribbon products, the operating efficiency of ribbon looms is constantly improving, and the yarn output speed needs frequent adjustments according to different product specifications and production rhythms. Traditional ribbon loom yarn guiding devices reveal many drawbacks when facing varying yarn output speeds. During high-speed yarn output, the yarn experiences significant tension fluctuations due to its own inertia. When the speed changes abruptly, the yarn experiences uneven stress instantaneously, easily deviating from its original running track and exhibiting slackness and swaying. The goal of the yarn guiding mechanism is to suppress yarn vibration and yarn entanglement, thereby ensuring the smooth operation of the textile mechanism. However, existing yarn guiding devices still have some shortcomings in the ribbon production field. For example, patent CN213595631U discloses a yarn guiding mechanism for textile machines, which has the following shortcomings in the yarn guiding field: it cannot adjust the size of the guide hole according to the yarn output speed, and it cannot control the yarn amplitude. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a yarn anti-tangling guiding device for a weaving machine, which solves the problems existing in the prior art. Through a carefully designed lead-out wheel, the tension can be adjusted at different lead-out speeds to counteract the inertia of the yarn at different speeds. Furthermore, through the cooperation of the guide wire mechanism and the lead-out wheel, it can automatically adapt to different lead-out speeds. By adjusting the size of the lead-out hole, the amplitude of the yarn can be limited at different lead-out speeds, thereby preventing the yarn from tangling due to vibration and ensuring the continuity of production.

Detailed Implementation

[0022] The following will refer to the appendix in the example of this utility model. Figure 1 -Appendix Figure 6 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides a technical solution: a yarn anti-tangle guiding device for a weaving machine, comprising a frame 1, a yarn wheel bracket 2 fixed to the upper end of the frame 1, a guide wire mechanism 3 fixed to the right side of the yarn wheel bracket 2, and a yarn outlet wheel 4 fixed to the right side of the guide wire mechanism 3; the frame 1 serves as the supporting structure for the entire yarn anti-tangle guiding device. It provides the mounting foundation for components such as the yarn wheel bracket 2, the guide wire mechanism 3, and the yarn outlet wheel 4, ensuring the relative position stability of each component during operation. The yarn wheel bracket 2, fixed to the upper end of the frame 1, is used to hold the yarn wheel. The yarn from the collector, after being constrained by the vibration by the guide wire mechanism 3, winds onto the yarn outlet wheel 4, causing the yarn outlet wheel 4 to rotate before entering the textile equipment.

[0024] The conductor guiding mechanism 3 includes a conductor support 301 fixed to the upper end of the frame 1, a slide bar 302 fixed inside the conductor support 301, a spring 303 fixed to the outside of the slide bar 302, a slider 304 fixed to the center of the slide bar 302, a conductor block 305 fixed to the side of the conductor support 301, and an adjusting block 306 fixed inside the conductor block 305. The conductor support 301, fixed to the upper end of the frame 1, provides a mounting base for components such as the slide bar 302, spring 303, slider 304, conductor block 305, and adjusting block 306. It is the skeleton of the conductor guiding mechanism 3, determining the installation position and relative relationship of each component. The slide bar 302, fixed inside the conductor support 301, serves as the sliding track for the slider 304. Simultaneously, it cooperates with the spring 303 to provide support and guidance for the movement of the slider 304. This allows the slider 304 to slide flexibly on the slide bar 302, adaptively adjusting according to the yarn tension and movement, thereby ensuring stable yarn guidance. Spring 303 is fixed to the outside of slide bar 302 and connected to slider 304. When the yarn is released from the collector, the yarn's relative position to slider 304 will move left and right. Spring 303 can buffer this positional change by extending and retracting, so that the positional change of the yarn when it enters conductor block 305 is not too large. Conductor block 305 is fixed to the side of conductor bracket 301, providing an installation position for adjusting block 306. Adjusting block 306 limits the vibration amplitude of the yarn through the size of the hole.

[0025] The adjusting block 306 includes an electric heating ring 3061 fixed inside the conductor block 305, an elastic rubber ring 3062 fixed inside the electric heating ring 3061, a brass ring 3063 fixed inside the elastic rubber ring 3062, and an iron-nickel alloy ring 3064 fixed inside the brass ring 3063. The electric heating ring 3061 generates heat after passing an electric current. The heat is conducted through the elastic rubber ring 3062 into the brass ring 3063 and the iron-nickel alloy ring 3064. When the temperature changes, the two layers of materials will bend due to their different thermal expansion rates. The brass has a higher coefficient of thermal expansion, while the iron-nickel alloy has a lower coefficient of thermal expansion. Therefore, the hole in the middle will become smaller after being heated. The elastic rubber ring 3062 can ensure that it fits against the outside of the brass ring 3063 to maintain support.

[0026] The yarn exit wheel 4 includes a yarn exit housing 401 fixed to the upper end of the frame 1, a fixing post 402 fixed inside the yarn exit housing 401, bearings 403 fixed at both ends of the fixing post 402, a stator 404 fixed in the middle of the bearings 403, a guide wheel 405 fixed outside the bearings 403, and a guide frame 406 fixed to the upper end of the yarn exit housing 401. The yarn exit housing 401 ensures the normal operation of the components inside the yarn exit wheel 4 and regulates the yarn's entry and exit routes through the inlet hole 4011 and the outlet hole 4012, which is beneficial for achieving stable yarn guidance and anti-tangling functions. The fixing post 402 is fixed inside the yarn exit housing 401 and is used to install the bearings 403 and the stator 404. It provides support and a fixed position for the bearings 403 and the stator 404, ensuring their normal operation. The bearings 403 ensure that the guide wheel 405 can rotate flexibly according to the yarn exit speed, reducing energy loss and improving the working efficiency of the device. The stator 404, in conjunction with the permanent magnet 4051, can adjust the rotational speed of the guide wheel 405, thereby adjusting the yarn tension. It also generates electricity using magnetic induction; the resulting current passes through the guide wire, is supported by the guide frame 406, and connects to the heating ring 3061 on the outside of the adjusting block 306, generating an electrothermal effect to adjust the orifice size. The guide wheel 405, fixed to the outside of the bearing 403, is the component that directly contacts and guides the yarn out. The yarn is wound around the outside of the guide wheel 405, and its rotation controls the outgoing tension. The guide frame 406 is used to hold the guide wire and transmit current to the heating ring 3061.

[0027] The cable exit housing 401 has a cable inlet hole 4011 at one end and a cable outlet hole 4012 at the other end. The cable inlet hole 4011, located at one end of the cable exit housing 401, is the entrance for the yarn to enter the cable exit wheel 4. It determines the position where the yarn enters the cable exit wheel 4, allowing the yarn to accurately enter subsequent components for guidance. The cable outlet hole 4012, located at the other end of the cable exit housing, is the exit for the yarn to leave the cable exit wheel 4. Furthermore, it further guides the yarn through cooperation with the guide ring 4013.

[0028] A guide ring 4013 is provided on the outside of the outlet hole 4012; the guide ring 4013 is used to change the direction of the yarn in advance so that the yarn can enter the textile mechanism more smoothly.

[0029] The guide wheel 405 is equipped with a permanent magnet 4051; the permanent magnet 4051 rotates to cause the stator 404 to cut magnetic field lines and generate current.

[0030] Working principle:

[0031] The yarn collector is placed on the yarn wheel bracket 2. After passing through the slider 304 and the adjusting block 306, the yarn is wound onto the guide wheel 405 and led out through the outlet hole 4012 into the textile equipment. When the textile speed of the textile equipment changes, the rotation speed of the guide wheel 405 changes, and the resistance of the stator 404 in cutting the magnetic lines of force also increases. Consequently, the rotational resistance of the guide wheel 405 also increases, thereby adjusting the yarn tension. When the rotation speed of the guide wheel 405 increases, the current generated by the stator 404 also increases. The conductor connects to the stator and then to the heating ring 4061 after passing through the guide frame 406. One end of the heating ring 4061 is connected to the conductor, and the other end is directly grounded through the frame 1. The heating ring 4061 can generate heat according to the current passing through it. The heat generated heats the brass ring 3063 and the iron-nickel alloy ring 3064, thereby adjusting the size of the central hole and limiting the vibration of the yarn at different speeds.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
