Description

Technical Field

[0001] This utility model relates to the field of weaving machine technology, specifically to a weaving machine guide mechanism. Background Technology

[0002] A loom, also called a spinning machine, weaving machine, or cotton spinning machine, was originally a manually operated loom. Looms are generally equipped with a fabric guiding mechanism, which guides the fabric during its transport.

[0003] Chinese utility model patent application number 202223375045.6 provides a fabric guiding mechanism for a weaving machine. Pulling the pull block causes the moving block to slide upwards. At this time, the sliding of the moving block causes the limiting shaft to slide downwards inside the limiting groove. Therefore, as the angle of the limiting groove decreases, the locking rod is restricted by the limiting shaft and disengages from the inside of the locking groove. At this time, the limiting ring can be moved easily, thus changing the distance between the two limiting rings. This allows the limiting rings to restrict fabrics of different widths, thereby preventing the fabric from shifting during the conveying process and ensuring the subsequent processing effect of the fabric.

[0004] However, during the use of the above equipment, it was found that because the chute is located on the third guide roller, when the fabric runs on the guide roller, the fabric and the edge of the chute will easily rub and scratch. This friction will be more obvious, especially when running at high speed or when the fabric tension is high. This friction can easily lead to wear, pilling, or even scratches on the fabric surface, affecting the quality and appearance of the fabric. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fabric guiding mechanism for a loom, which solves the problem mentioned in the background art that the edge of the groove on the third guide roller is prone to friction and scratching with the fabric, especially under high-speed operation or high fabric tension, resulting in wear, pilling, or even scratches on the fabric surface, affecting the quality and appearance of the fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric guiding mechanism for a weaving machine, comprising a support frame and a third guide roller, wherein the third guide roller is rotatably mounted on the support frame, and an adjusting component is provided in the support frame, the adjusting component comprising a bidirectional threaded rod, the bidirectional threaded rod being disposed below the third guide roller and rotatably mounted on the support frame, a sliding rod being arranged parallel below the bidirectional threaded rod, the sliding rod being fixedly mounted on the support frame, and two symmetrical movable frames being slidably mounted on the sliding rod, the movable frames being helically connected to the bidirectional threaded rod, and a limiting ring being fixedly mounted at the top of the movable frame, the limiting ring being sleeved on the third guide roller.

[0007] Preferably, a fixing rod is fixedly installed on the support frame. The fixing rod is located on one side of the movable frame. The top of the fixing rod is set as an inclined surface. A scale is set on the inclined surface. The marking size of the scale gradually increases from the middle as the origin to both ends.

[0008] Preferably, a rotating handle is provided on the outer side of the support frame, the rotating handle is fixedly connected to a bidirectional threaded rod, a limiting plate is fixedly provided on one end of the rotating handle, and limiting holes are evenly opened on the periphery of the limiting plate.

[0009] Preferably, a fixing frame is fixedly installed on the outer side of the support frame, a limit rod is slidably installed in the fixing frame, a lever is fixedly installed on the limit rod, and one end of the limit rod is adapted to a limiting hole.

[0010] Preferably, the fixed frame is provided with a movable groove, and the two ends of the movable groove are respectively provided with a limiting groove one and a limiting groove two. Both the limiting groove one and the limiting groove two are semi-circular arc-shaped, and their width is adapted to the lever plate.

[0011] This utility model provides a fabric guiding mechanism for a weaving machine. It has the following beneficial effects:

[0012] (1) This utility model controls the moving frame to move the limiting ring by a bidirectional threaded rod, so as to adapt to the width of different fabrics, reduce the impact on the third guide roller, and avoid the problems of fabric surface wear, fuzzing and scratches caused by friction and scratching of the groove edge on the third guide roller.

[0013] (2) By setting up a fixed frame and a scale, this utility model enables precise control and calculation of the size between the two limiting rings, making it more adaptable to fabrics of different widths.

[0014] (3) By setting a limiting rod and a limiting hole, the limiting rod enters the corresponding limiting hole to restrict the limiting plate, thereby avoiding the unexpected rotation of the handle and improving the stability of the distance between the two limiting rings.

[0015] This solves the problem that the edge of the groove on the third guide roller can easily rub and scratch the fabric, especially when running at high speed or when the fabric tension is high, which can cause wear, pilling or even scratches on the fabric surface, affecting the quality and appearance of the fabric.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-4 A fabric guiding mechanism for a weaving machine includes a support frame 1 and a third guide roller 11. The third guide roller 11 is rotatably mounted on the support frame 1. An adjustment component 2 is provided in the support frame 1. The adjustment component 2 includes a bidirectional threaded rod 21, which is located below the third guide roller 11 and rotatably mounted on the support frame 1. A slide rod 22 is arranged parallel below the bidirectional threaded rod 21 and is fixedly mounted on the support frame 1. Two symmetrical movable frames 23 are slidably mounted on the slide rod 22. The movable frames 23 are helically connected to the bidirectional threaded rod 21. A limit ring 24 is fixedly mounted at the top of the movable frame 23 and is sleeved on the third guide roller 11.

[0024] A fixed rod 12 is fixedly installed on the support frame 1. The fixed rod 12 is located on one side of the movable frame 23. The top of the fixed rod 12 is set as an inclined surface 121. A scale 122 is set on the inclined surface 121. The marking size of the scale 122 gradually increases from the middle as the origin to both ends.

[0025] Specifically, when the bidirectional threaded rod 21 is rotated, since the movable frame 23 is helically connected to the bidirectional threaded rod 21 and the movable frame 23 slides on the slide rod 22, the two movable frames 23 will move relative to each other or away from each other on the slide rod 22 when the bidirectional threaded rod 21 is rotated. When it is necessary to adapt to a wider fabric, the bidirectional threaded rod 21 is rotated in the opposite direction so that the two movable frames 23 move away from each other. When it is necessary to adapt to a narrower fabric, the bidirectional threaded rod 21 is rotated in the forward direction so that the two movable frames 23 move towards each other.

[0026] A limiting ring 24 is fixedly installed at the top of the movable frame 23. The limiting ring 24 is sleeved on the third guide roller 11. The movement of the movable frame 23 will drive the limiting ring 24 to move, thereby changing the effective width of the third guide roller 11 through which the fabric can pass. The limiting ring 24 does not directly contact the third guide roller 11, avoiding direct friction between the limiting ring 24 and the third guide roller 11, thereby reducing the wear of parts caused by friction, maintaining the smoothness and integrity of the surface of the third guide roller 11, extending the service life of the third guide roller 11 and the limiting ring 24, and reducing the maintenance cost and replacement frequency of the equipment.

[0027] The inclined surface 121 and scale 122 on the fixed rod 12 provide the operator with an intuitive adjustment reference. The operator can accurately control the rotation angle of the bidirectional threaded rod 21 and the moving distance of the moving frame 23 according to the scale 122, thereby achieving precise adjustment of the position of the limit ring 24, better adapting to fabrics of different widths, and reducing the need for repeated adjustments due to inaccurate adjustment.

[0028] Example 2:

[0029] To avoid unexpected rotation of the bidirectional threaded rod 21, please refer to... Figures 1-4 Based on embodiment 1, a rotating handle 3 is provided on the outer side of the support frame 1. The rotating handle 3 is fixedly connected to the bidirectional threaded rod 21. A limiting disk 31 is fixedly provided on one end of the rotating handle 3. Limiting holes 32 are evenly opened on the periphery of the limiting disk 31.

[0030] A fixed frame 4 is fixedly installed on the outside of the support frame 1. A limit rod 44 is slidably installed in the fixed frame 4. A lever 45 is fixedly installed on the limit rod 44. One end of the limit rod 44 is correspondingly matched with the limit hole 32.

[0031] The fixed frame 4 has a movable groove 42. The two ends of the movable groove 42 are respectively provided with a first limiting groove 41 and a second limiting groove 43. Both the first limiting groove 41 and the second limiting groove 43 are semi-circular arcs, and their widths are adapted to the lever plate 45.

[0032] Specifically, after the bidirectional threaded rod 21 rotates to the desired position, the limiting rod 44 is inserted into the limiting hole 32 of the limiting plate 31, so that one end of the limiting rod 44 is matched with the limiting hole 32, thereby restricting the rotation of the limiting plate 31 and the bidirectional threaded rod 21 fixedly connected to it, preventing them from rotating unexpectedly due to factors such as machine vibration and changes in fabric tension; limiting groove 1 41 and limiting groove 2 43 are provided at both ends of the moving groove 42 of the fixed frame 4, and their widths are matched with the lever plate 45. When the limiting rod 44 is inserted into the limiting hole 32, the lever 45 will be in the limiting groove 41. The lever 45 will be blocked by the limiting groove 41, further restricting the movement of the limiting rod 44, thereby enhancing the limiting effect on the bidirectional threaded rod 21 and preventing it from rotating unexpectedly. When it is necessary to rotate the bidirectional threaded rod 21, the operator rotates the lever 45 to drive the limiting rod 44 to rotate in the moving groove 42. When the lever 45 rotates into the moving groove 42, the lever 45 can move along the moving groove 42 to the limiting groove 43. Under the action of gravity, the lever 45 automatically rotates into the limiting groove 43, thereby using the limiting groove 43 to restrict the lever 45, so that the limiting rod 44 is disengaged from the limiting hole 32, making it convenient for the operator to control the rotation of the bidirectional threaded rod 21 by rotating the handle 3.

[0033] Working principle: The operator first observes the scale 122 on the inclined surface 121 of the fixed rod 12, determines the length of the distance between the limiting rings 24 to be adjusted according to the width of the fabric, and drives the bidirectional threaded rod 21 to rotate by rotating the handle 3. When the bidirectional threaded rod 21 rotates, the two moving frames 23 will move relative to or away from each other on the slide rod 22. When a wider fabric needs to be accommodated, the bidirectional threaded rod 21 is rotated in the opposite direction, so that the two moving frames 23 move away from each other; when a narrower fabric needs to be accommodated, the bidirectional threaded rod 21 is rotated in the forward direction, so that the two moving frames 23 move towards each other. The movement of the moving frames 23 will drive the limiting rings 24 to move, thereby changing the effective width of the fabric that can pass through on the third guide roller 11, so as to adapt it to the width of the fabric.

[0034] After the bidirectional threaded rod 21 is rotated to the desired position, the limiting rod 44 is inserted into the limiting hole 32 of the limiting plate 31, thereby restricting the rotation of the limiting plate 31 and the bidirectional threaded rod 21 fixedly connected to it. When the length needs to be adjusted again, the limiting rod 44 is rotated in the moving groove 42 by rotating the dial plate 45. When the dial plate 45 rotates into the moving groove 42, the dial plate 45 can move along the moving groove 42 to the second limiting groove 43. Under the action of gravity, the dial plate 45 automatically rotates into the second limiting groove 43, thereby using the second limiting groove 43 to restrict the dial plate 45, so that the limiting rod 44 is disengaged from the limiting hole 32. The operator can then control the rotation of the bidirectional threaded rod 21 by rotating the handle 3 to adjust the spacing of the limiting ring 24.
