A yarn guiding mechanism for textile machines

Abstract

This utility model belongs to the field of textile yarn technology, specifically a yarn guiding mechanism for textile machines. It includes a mounting platform with multiple external brackets fixedly connected to its rear edge. External bolts are threaded onto the surfaces of the external brackets. A main shaft is fixedly mounted at the center of the lower front half of the mounting platform. A movable block is located on the side of the main shaft, and an adjustment mechanism is installed inside the movable block. An extension mechanism is located at the rear end of the mounting platform. Through the combined action of the adjustment mechanism and the extension mechanism, the range of yarn tension and the guiding angle can be flexibly adjusted. When the yarn tension fluctuates, the adjustment column slides within the movable block and, with the elastic reset of the spring, can immediately offset excess tension or supplement tension, preventing yarn breakage or slack. Simultaneously, the extension mechanism drives the movable block to rotate along an arc path via an electric push rod, which can quickly change the orientation of the yarn guide wheel, thereby adjusting the basic range of tension.

Description

Technical Field

[0001] This utility model belongs to the field of textile yarn technology, specifically a yarn guiding mechanism for textile machines. Background Technology

[0002] In the textile production process, the yarn guiding mechanism is a key component of the textile machine. Its main function is to guide the yarn to run stably along a preset path in the textile process, ensuring that the yarn remains in an orderly state in stages such as drafting and weaving, which directly affects the quality of textile products and production efficiency.

[0003] However, in actual textile production, different sizes of yarn require different tension ranges during processing. The tension adjustment range of traditional yarn guiding mechanisms is relatively fixed and the adjustment range is small. During the production process, the yarn is prone to breakage due to tension mismatch, which in turn affects the efficiency of the work. Therefore, this utility model provides a yarn guiding mechanism for textile machines. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problems raised in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The yarn guiding mechanism for a textile machine described in this utility model includes a mounting platform, a plurality of external brackets are fixedly connected to the rear edge of the mounting platform, external bolts are threadedly connected to the surface of the external brackets, a main shaft is fixedly installed at the center of the lower half of the front end of the mounting platform, a movable block is provided at the side end of the main shaft, an adjustment mechanism is provided inside the movable block, and an extension mechanism is provided at the rear end of the mounting platform.

[0006] Preferably, two rotating rings are rotatably connected to the surface of the main shaft, and limiting plates are fixedly installed at both ends of the main shaft. Movable blocks are fixedly connected to the surface of the rotating rings, and the two movable blocks are installed in a staggered manner.

[0007] Preferably, the adjustment mechanism includes an adjustment column, a mounting frame, a yarn guide wheel, and a spring. The adjustment column is slidably installed inside the movable block, and the mounting frame is fixedly installed at the outer end of the adjustment column. The yarn guide wheel is rotatably connected inside the outer end of the mounting frame. A buffer groove is provided at the connection between the outer end of the movable block and the adjustment column. A spring is sleeved between the surface of the adjustment column and the mounting frame corresponding to the buffer groove.

[0008] Preferably, a sliding groove is provided inside the movable block corresponding to the inner end of the adjusting column, and a limiting ring is slidably installed inside the sliding groove, with the limiting ring fixedly connected to the inner end of the adjusting column.

[0009] Preferably, a connecting column is fixedly installed on the inner end surface of the movable block, and an arc-shaped groove is provided on the surface of the mounting platform corresponding to the position of the connecting column. A limiting collar is fixedly installed on the surface of the arc-shaped groove corresponding to the rear end of the mounting platform.

[0010] Preferably, the extension mechanism includes a fixed column and an electric push rod. The fixed column is fixedly installed on the upper half of the rear end of the mounting platform. The electric push rod is hinged to the surface of the fixed column, and the other end of the electric push rod is hinged to the surface of the limiting collar.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The yarn guiding mechanism for a textile machine described in this utility model, through the coordinated action of the adjusting mechanism and the stretching mechanism, allows for flexible adjustment of the yarn tension range and the guiding angle. When the yarn tension fluctuates, the adjusting column slides within the movable block and, in conjunction with the elastic reset of the spring, can offset excess tension or supplement tension in real time, preventing yarn breakage or slack. Simultaneously, the stretching mechanism drives the movable block to rotate along an arc path via an electric push rod, which can quickly change the orientation of the yarn guiding wheel, thereby adjusting the basic range of tension.

[0013] 2. The yarn guiding mechanism for a textile machine described in this utility model avoids mutual interference between the rotating rings during the guiding process by using a staggered installation of the movable block and a rotating connection structure between the rotating ring and the main shaft; the cooperation between the limiting ring and the sliding groove at the inner end of the adjusting column, as well as the setting of the buffer groove and the spring, not only ensures the stability of the adjustment process.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, the yarn guiding mechanism for a textile machine according to this utility model includes a mounting platform 1. Multiple external frames 2 are fixedly connected to the rear edge of the mounting platform 1. External bolts 3 are threaded onto the surface of the external frames 2. A main shaft 4 is fixedly mounted at the center of the lower half of the front end of the mounting platform 1. A movable block 6 is provided on the side end of the main shaft 4. An adjustment mechanism is provided inside the movable block 6. An extension mechanism is provided at the rear end of the mounting platform 1. The yarn guiding mechanism is mounted on the mounting platform 1 and is fixed to the main body of the textile machine by the external frames 2 and external bolts 3 to ensure the stability of the overall structure. The main shaft 4 at the front end serves as the core rotation support component. The limiting discs at both ends restrict the axial displacement of the rotating ring 5, allowing the rotating ring 5 to rotate flexibly around the main shaft 4.

[0023] Two rotating rings 5 ​​are rotatably connected to the surface of the main shaft 4. Limiting discs are fixedly installed at both ends of the main shaft 4. Movable blocks 6 are fixedly connected to the surface of the rotating rings 5. The two movable blocks 6 are installed in a staggered manner to prevent the two rotating rings 5 ​​from interfering with each other during rotation.

[0024] The adjustment mechanism includes an adjustment column 7, a mounting frame 9, a yarn guide wheel 10, and a spring 11. The adjustment column 7 is slidably installed inside the movable block 6. The mounting frame 9 is fixedly installed at the outer end of the adjustment column 7. The yarn guide wheel 10 is rotatably connected inside the outer end of the mounting frame 9. A buffer groove is provided at the connection between the outer end of the movable block 6 and the adjustment column 7. The spring 11 is sleeved between the buffer groove and the mounting frame 9 on the surface of the adjustment column 7. When the yarn tension fluctuates, the pressure on the yarn guide wheel 10 will be transmitted to the mounting frame 9 and the adjustment column 7. The adjustment column 7 can slide in the sliding groove inside the movable block 6, and the spring 11 sleeved on its surface is located between the buffer groove of the movable block 6 and the mounting frame 9.

[0025] The inner end of the movable block 6 corresponds to the inner end of the adjusting column 7, and a sliding groove is provided. A limiting ring 8 is slidably installed inside the sliding groove. The limiting ring 8 is fixedly connected to the inner end of the adjusting column 7. The limiting ring 8 at the inner end of the adjusting column 7 ensures stable sliding and limits the range of motion of the adjusting column 7.

[0026] A connecting post 12 is fixedly installed on the inner end surface of the movable block 6. An arc-shaped groove 13 is set on the surface of the mounting platform 1 corresponding to the position of the connecting post 12. A limiting collar 14 is fixedly installed on the surface of the arc-shaped groove 13 corresponding to the rear end of the mounting platform 1. The connecting post 12 at the inner end of the movable block 6 is embedded in the arc-shaped groove 13 on the surface of the mounting platform 1, and the end of the connecting post 12 is connected to the limiting collar 14. The arc-shaped groove 13 restricts the movement trajectory of the connecting post 12, ensuring that the movable block 6 adjusts its angle along the arc-shaped path.

[0027] The extension mechanism includes a fixed column 16 and an electric push rod 15. The fixed column 16 is fixedly installed on the upper half of the rear end of the mounting platform 1. The electric push rod 15 is hinged to the surface of the fixed column 16. The other end of the electric push rod 15 is hinged to the surface of the limiting collar 14. The fixed column 16 serves as a fulcrum. The limiting collar 14 slides along the arc groove 13 through the extension and retraction of the electric push rod 15. The electric push rod 15 is existing technology and therefore is not described in detail.

[0028] Working Principle: The yarn guiding mechanism is mounted on the mounting platform 1 and fixed to the main body of the textile machine via the external frame 2 and external bolts 3, ensuring overall structural stability. The main shaft 4 at the front end serves as the core rotational support component, and the limiting discs at both ends restrict the axial displacement of the rotating ring 5, allowing the rotating ring 5 to rotate flexibly around the main shaft 4. The movable block 6 fixedly connected to the surface of the rotating ring 5 is installed in a staggered manner to prevent the two rotating rings 5 ​​from interfering with each other during rotation. The yarn guide wheel 10 at the outer end of the movable block 6 is the component that directly contacts the yarn and is connected to the adjusting column 7 via the mounting frame 9. When the yarn passes through the surface of the yarn guide wheel 10, its rotational characteristics reduce friction and reduce yarn wear. When the yarn tension fluctuates, the pressure on the yarn guide wheel 10 is transmitted to the mounting frame 9 and the adjusting column 7. The adjusting column 7 can slide in the sliding groove inside the movable block 6, and the spring 11 sleeved on its surface is located between the buffer groove of the movable block 6 and the mounting frame 9. If the yarn tension increases, the guide wheel 10 drives the adjusting column 7 to retract into the movable block 6, the spring 11 is compressed and generates a reverse elastic force, which offsets part of the tension to protect the yarn; if the tension decreases, the spring 11 resets and pushes the adjusting column 7 to extend outward, so that the yarn is kept at a moderate tension, realizing adaptive buffering and adjustment of tension. The connecting column 12 at the inner end of the movable block 6 is embedded in the arc groove 13 on the surface of the mounting platform 1, and the end of the connecting column 12 is connected to the limiting collar 14. The arc groove 13 restricts the movement trajectory of the connecting column 12, ensuring that the movable block 6 adjusts the angle along the arc path. When it is necessary to adjust the yarn guide angle, the fixed column 16 at the rear end of the mounting platform 1 serves as a fulcrum. The electric push rod 15 extends and retracts, driving the limiting collar 14 to slide along the arc groove 13, and then the connecting column 12 pulls the movable block 6 to rotate around the main shaft 4 through the rotating ring 5, ultimately changing the orientation of the guide wheel 10 and completing the adjustment of the guide angle.
