Description

Technical Field

[0001] The invention discloses a weft yarn defect processing device, belonging to the technical field of textiles. Background Art

[0002] In the current increasingly competitive market environment, customers are increasingly demanding product quality, with almost zero defects. Currently, according to the weaving process requirements of different fabrics, the requirements for warp and weft are even more stringent, and there are strict grade requirements for the selection of raw materials for warp yarns. Weft yarns undergo corresponding process treatments during production according to the weaving requirements of different specifications. The control of weft yarns is prone to loopholes in the preparation process. Each weft yarn is not equipped with the corresponding treatment equipment during weaving. The weft yarns themselves may be rough, uneven, oily, or have other problems caused by production. It is difficult for operators to detect and handle such defects in a timely manner during weft unwinding. Defects must be formed on the silk surface before they can be discovered. Once formed on the silk surface, they cannot be reversed, resulting in poor product quality stability.

[0003] CN104178892A discloses an instant cloth quality detection system, in which bearings are arranged on both sides of the weft yarn, and the displacement of the bearings is detected by proximity switches, thereby detecting whether the weft yarn has defects. However, the weft yarn is very thin, and defects can be easily flattened by the bearings, so many defects cannot be accurately detected. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the existing technology and provide a weft yarn defect processing device, which can effectively remove weft yarn defects, prevent the generation of more defects, and greatly improve product quality.

[0006] Preferably, the yarn length detection sensor is fixed on the fixing bracket via a sensor fixing seat;

[0007] The sensor fixing seat includes a sensor fixing plate and a bracket connecting plate. The sensor fixing plate is horizontally arranged. The bracket connecting plate is an arc structure. One end of the sensor fixing plate is fixedly connected to the bracket connecting plate. The yarn line detection sensor is fixed on the sensor fixing plate.

DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 5 The utility model is further described.

[0024] Example 1

[0025] Reference Figure 1 The weft yarn defect processing device includes a fixed bracket 1, a first yarn guide assembly 2, a second yarn guide assembly 3, a third yarn guide assembly 4 and a yarn line detection sensor 5. The first yarn guide assembly 2 and the second yarn guide assembly 3 are respectively arranged on the fixed bracket 1, and the yarn line detection sensor 5 is fixed to the fixed bracket 1 through a sensor fixing seat 6; the yarn line detection sensor 5 is arranged between the first yarn guide assembly 2 and the second yarn guide assembly 3, and the third yarn guide assembly 4 is arranged on one side of the yarn line detection sensor 5. The weft yarn 10 passes through the first yarn guide assembly 2, the second yarn guide assembly 3 and the third yarn guide assembly 4 in sequence, and the yarn line detection sensor 5 is connected to the controller.

[0026] The yarn length detection sensor 5 in this embodiment is a fiber optic amplifier. The specific model is ER2-18ZW, branded by Boyi Jingke. The fiber optic amplifier can detect the length of the weft yarn 10, that is, the diameter of the weft yarn 10. The diameter of a defective weft yarn 10 is larger than the normal diameter of the weft yarn 10, so the fiber optic amplifier can determine whether the weft yarn 10 has a defect.

[0027] The fixed bracket 1 in this embodiment is L-shaped, the first yarn guide assembly 2 and the second yarn guide assembly 3 are respectively arranged on the two arms of the fixed bracket 1, the third yarn guide assembly 4 is connected to the fixed bracket 1 through a connecting plate, and the sensor fixing seat 6 and the connecting plate are fixedly connected to the fixed bracket 1 by a bolt.

[0028] See also Figure 2The first yarn guide assembly 2, the second yarn guide assembly 3 and the third yarn guide assembly 4 have the same structure. The first yarn guide assembly 2, the second yarn guide assembly 3 and the third yarn guide assembly 4 all have a horizontal fixed plate and a yarn guide vertical plate fixed on the fixed plate. A plurality of yarn guide holes 7 are opened on the yarn guide vertical plate, and the weft yarn 10 is arranged to pass through the two yarn guide holes 7 of the second yarn guide assembly 3.

[0029] The weft yarn 10 on the weft accumulator first passes through a yarn guide hole 7 of the first yarn guide assembly 2, then passes through the upper side of the yarn length detection sensor 5, and then passes through a yarn guide hole 7 of the second yarn guide assembly 3. The weft yarn 10 then passes through another yarn guide hole 7 of the second yarn guide assembly 3 in the opposite direction, and then passes through a yarn guide hole 7 of the third yarn guide assembly 4, and finally enters the loom.

[0030] In this embodiment, a plurality of yarn guide sleeves 8 are provided in the yarn guide hole 7, and the weft yarn 10 passes through the yarn guide sleeves 8. The yarn guide sleeves 8 are made of plastic material to prevent the weft yarn 10 from being worn and improve the quality of the fabric.

[0031] See also Figure 3 The sensor fixing seat 6 includes a sensor fixing plate 601 and a bracket connecting plate 602. The sensor fixing plate 601 is horizontally arranged, and the bracket connecting plate 602 is an arc structure. One end of the sensor fixing plate 601 is fixedly connected to the bracket connecting plate 602, and the yarn line detection sensor 5 is fixed on the sensor fixing plate 601.

[0032] The fixed bracket 1 is connected via an arc-shaped bracket connecting plate 602. During the connection process, the bracket connecting plate 602 is deformed, thereby firmly fixing the sensor fixing seat 6 on the fixed bracket 1, preventing the vibration of the loom during operation from causing the yarn detection sensor 5 to shake, thereby ensuring accurate detection results.

[0033] Working process: The weft yarn 10 in the weft accumulator passes through a yarn guide hole 7 of the first yarn guide assembly 2, passes above the yarn length detection sensor 5, then passes through a yarn guide hole 7 of the second yarn guide assembly 3, passes back through another yarn guide hole 7 of the second yarn guide assembly 3, passes through a yarn guide hole 7 of the third yarn guide assembly 4, and enters the loom. When the yarn length detection sensor 5 detects a sudden increase in the diameter of the weft yarn 10, indicating a defect, the controller controls the loom to stop.

[0034] Example 2

[0035] See also Figure 4 In this embodiment, a weft tensioning mechanism is provided between the third yarn guide assembly 4 and the connecting plate. This weft tensioning mechanism ensures that the weft yarn 10 is always straightened, preventing the weft yarn 10 from falling due to loss of traction, and ensuring accurate detection. The third yarn guide assembly 4 in this embodiment is the same as that in Example 1.

[0036] Specifically, the weft yarn tensioning mechanism is a spring 9, and the third yarn guide assembly 4 is rotated to connect the connecting plate. The spring 9 is arranged between the third guide assembly and the connecting plate. When the traction force is temporarily lost, the spring 9 pushes the third yarn guide assembly 4 to swing to the side away from the yarn line detection sensor 5, thereby straightening the weft yarn 10.

[0037] Example 3

[0038] See also Figure 5 In this embodiment, the third yarn guide assembly 4 is a yarn guide wheel, and the weft yarn 10 is wound around the side of the yarn guide wheel away from the yarn length detection sensor 5. In this embodiment, a spring 9 is also provided between the third guide assembly and the connecting plate. When traction is temporarily lost, the spring 9 pushes the third yarn guide assembly 4 to swing away from the yarn length detection sensor 5, thereby straightening the weft yarn 10.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
