Technical Field
[0001] This utility model relates to the field of air-jet loom technology, and in particular to a selvage yarn transport device for air-jet looms. Background Technology
[0002] Air jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. Fabrics woven with them will have raw edges. Therefore, in order to improve the quality of the fabric, the equipment is usually equipped with a raw edge cutting device to cut off the raw edges of the fabric. This will produce waste edges, which need to be collected by an automatic conveying device.
[0003] Currently, the utility model with publication number CN208917427U proposes a yarn conveying device for an air-jet loom, including a yarn guide and a pulling assembly. The pulling assembly includes a pressure roller, a drive component, and a pressure roller. The drive component is mounted on the frame and its output shaft is coaxially connected to the pressure roller. The pressure roller is mounted on the frame via an adjustment assembly. The adjustment assembly includes a slide rail mounted on the frame, a slider slidably connected to the slide rail, and an adjusting screw threadedly connected to the frame. The adjusting screw is rotatably connected to the slider and engaged along the length of the adjusting screw. The pressure roller is rotatably connected to the slider. When the slider slides in the slide rail, the pressure roller moves closer to or further away from the pressure roller.
[0004] However, the existing technology has its shortcomings in use: the small contact area between the waste strip and the pressure roller and pressure wheel results in low friction, which easily leads to the problem of waste strip traction and slippage, causing the waste strip to be stuck during transmission.

A pressure roller 21 is provided on one side of the frame 1, and the pressure roller 21 abuts against the selvage yarn 3. Two drive rollers 22 are rotatably connected to one side of the frame 1. The same elastic conveyor belt 24 is connected to the two drive rollers 22. The outer side of the elastic conveyor belt 24 abuts against the selvage yarn 3. Two adjusting rollers 23 are connected to the elastic conveyor belt 24. Through the cooperative design between the frame 1 and the conveying mechanism 2, it is not only convenient to convey selvage yarn 3 of different thicknesses, but also to adjust the contact area between the selvage yarn 3, the elastic conveyor belt 24, and the pressure roller 21 according to the user's needs. Moreover, the structure is simple, which greatly improves the flexibility and practicality.
[0030] In this embodiment, an adjusting plate 25 and an adjusting plate 26 are rotatably connected to the shaft of the pressure roller 21. A fixed rod 29 is slidably installed on both the adjusting plate 25 and the adjusting plate 26. Two adjusting rollers 23 are rotatably connected to the two fixed rods 29 respectively, and are used to adjust the rotation of the two adjusting rollers 23.
[0031] In this embodiment, a sliding groove is provided on the adjusting plate 25, and a slider 27 is slidably connected in the sliding groove. One of the two fixed rods 29 is fixedly connected to the slider 27. A spring 28 is fixedly connected to one side of the slider 27, and one end of the spring 28 is fixedly connected to the adjusting plate 25 for adjusting the adjusting roller 23 on the adjusting plate 25.
[0032] In this embodiment, a sliding groove is provided on the second adjusting plate 26, and a slider 27 is slidably connected in the second sliding groove. One of the two fixed rods 29 is fixedly connected to the slider 27. A spring 28 is fixedly installed in the second sliding groove, and one end of the spring 28 is fixedly connected to the slider 27 for moving and adjusting the adjusting roller 23 on the second adjusting plate 26.
[0033] In this embodiment, one end of the first adjusting plate 25 and the second adjusting plate 26 are threadedly connected to a limiting rod 7. Both limiting rods 7 are threadedly connected to the frame 1 and are used to limit and fix the first adjusting plate 25 and the second adjusting plate 26.
[0034] In this embodiment, the frame 1 is provided with multiple limiting holes 8, which are arranged at equal intervals on the frame 1 and are adapted to two limiting rods 7, so as to facilitate the connection between the limiting rods 7 and the frame 1. One end of each of the two limiting rods 7 is fixedly connected to a rotating plate, so as to facilitate the rotation of the two limiting rods 7.
[0035] In this embodiment, an anti-slip rubber sleeve 5 is fixedly sleeved on the pressure roller 21. The anti-slip rubber sleeve 5 abuts against the twisted yarn 3. A groove is opened on the elastic conveyor belt 24. An anti-slip rubber 6 is fixedly installed in the groove. The anti-slip rubber 6 abuts against the twisted yarn 3. The anti-slip rubber 6 has a certain elasticity and is used to increase the friction between the twisted yarn 3, the elastic conveyor belt 24, and the pressure roller 21.
[0036] In this embodiment, a collection box 4 is provided on one side of the frame 1, and the twisted yarn 3 falls into the collection box 4 for collecting the twisted yarn 3.
[0037] Working principle: When in use, first pass one end of the twisted yarn 3 through the elastic conveyor belt 24 and the pressure roller 21, and then the twisted yarn 3 is conveyed by the cooperation between the pressure roller 21 and the elastic conveyor belt 24.
[0038] When the thickness of the selvage yarn 3 changes, the slider 27 slides on the adjusting plate 25 and adjusting plate 26 through the cooperation of the spring 28, the slider 27, and the fixing rod 29. The fixing rod 29 drives the two adjusting rollers 23 to move synchronously, thereby achieving the effect of automatically adjusting the distance between the two adjusting rollers 23 and the pressure roller 21. At this time, since the elastic conveyor belt 24 is elastic, the elastic conveyor belt 24 will change with the movement of the two adjusting rollers 23, thereby achieving the effect of adjusting the distance between the elastic conveyor belt 24 and the pressure roller 21, thus facilitating the conveying of selvage yarn 3 of different thicknesses.
[0039] By rotating the adjusting plate 25, the adjusting plate 25 drives the corresponding adjusting roller 23 to rotate around the axis of the pressure roller 21 by a certain angle through the transmission of the slider 27 and the fixed rod 29. During this process, the elastic conveyor belt 24 also changes due to its own elastic potential energy, thereby achieving the effect of adjusting the size of the included angle between the two adjusting rollers 23, thereby achieving the effect of adjusting the size of the contact area between the twisted yarn 3 and the elastic conveyor belt 24 and the pressure roller 21, thereby achieving the effect of preventing the twisted yarn 3 from slipping and being stuck during the conveying process.
[0040] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, it not only facilitates the conveying of twisted yarn 3 of different thicknesses, but also allows for the adjustment of the contact area between the twisted yarn 3, the elastic conveyor belt 24, and the pressure roller 21 according to user needs, thus preventing the twisted yarn 3 from slipping or becoming stuck during conveying, and greatly improving its practicality.
