Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a yarn separating device for a reed threading machine. Background Technology

[0002] A reed threading machine is a type of textile machinery primarily used to thread yarn through a reed for subsequent weaving. Its advantages include high automation, high precision, and wide applicability. It can handle various specifications and types of yarn and achieves efficient and precise threading operations, effectively improving weaving efficiency and product quality.

[0003] Chinese Patent Publication No. (CN219079778U) discloses a yarn separating device for a reed threading machine, including a clamp and a mounting plate. The clamp holds both ends of a yarn, and a yarn hook is used to sequentially hook a single yarn. The hooked yarn is then cut by scissors. Baffles are fixedly connected to both ends of the rear surface of the mounting plate. A yarn blowing mechanism and a moving mechanism are provided on the rear surface of the mounting plate. A limiting groove is formed on the rear surface of the mounting plate, and a limiting slide is provided inside the limiting groove, which is slidably connected to the limiting groove. This yarn separating device for a reed threading machine can blow the cut yarn away from the working area of ​​the yarn hook, preventing the cut warp yarn from falling directly into the working area of ​​the yarn separating device's yarn hook and near the detection head, thus affecting the yarn hook's hooking accuracy and the detection accuracy of the detection head, thereby improving the yarn separating accuracy.

[0004] However, the above-mentioned utility model still has the following problems: Although the above-mentioned utility model can blow the cut yarn away from the working area of ​​the hook needle, it is very easy for the yarn to become tangled or knotted during the process of blowing the yarn away, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a yarn separating device for a reed threading machine, which has the effect of preventing yarn from tangling and knotting.

Then, the servo motor drives the threaded rod to rotate, and through the transmission of the threaded rod, threaded slide, and connecting rod, the moving seat drives the yarn separating guide roller and clamping plate to move until the yarn leaves the working area of ​​the yarn separating hook. This design realizes the function of adjusting the position of the cut yarn, which can effectively avoid the cut yarn from affecting the yarn separating working area, and can also avoid the yarn from getting tangled and knotted when the yarn is blown away by wind. Thus, the device achieves the characteristic of preventing the yarn from getting tangled and knotted after being cut.

[0008] A further feature of this invention is that an anti-slip pad is fixedly connected to the lower surface of the clamping plate, and the lower surface of the anti-slip pad is provided with anti-slip texture.

[0009] By adopting the above technical solution and setting anti-slip pads, the friction between the clamp and the yarn can be increased, thereby enhancing the clamp's ability to fix the yarn.

[0017] By adopting the above technical solution and setting the first slide rail and slide groove, the stability of the moving seat when moving on the back plate surface can be improved, thereby improving the smoothness of the yarn separating guide roller when moving.

[0018] A further feature of this invention is that a front plate is fixedly connected to the upper surface of the support base, a second slide rail is fixedly connected to the inner side of the front plate, a slide block is slidably connected to the outer surface of the second slide rail, and the yarn separating guide roller is rotatably connected to the slide block.

[0019] By adopting the above technical solution and setting a second slide rail and slide block, the stability of the yarn separating guide roller when driving the yarn to adjust its position can be improved.

Then, the second cylinder works to drive the moving clamping roller to move to the right, cooperating with the auxiliary clamping roller to complete the clamping and fixing of the yarn. Finally, the first cylinder works again to drive the moving clamping roller and the auxiliary clamping roller to descend, which can straighten the cut yarn, thereby further improving the device's effectiveness in preventing yarn knotting and tangling.

[0024] A further feature of this invention is that a movable groove is provided on the upper surface of the drive seat, and the limiting rod is slidably connected to the movable groove.

[0025] By adopting the above technical solution and setting the moving groove, it is easy to fix the limiting rod to the moving clamping roller bracket, and it also plays a role in limiting the moving distance of the moving clamping roller.

Then, the servo motor drives the threaded rod to rotate, and through the transmission of the threaded rod, threaded slide, and connecting rod, the moving seat drives the yarn-separating guide roller and clamping plate to move until the yarn leaves the working area of ​​the yarn-separating hook. This design realizes the function of adjusting the position of the cut yarn, which can effectively avoid the cut yarn from affecting the yarn-separating working area, and can also avoid the yarn from being blown away by wind. The device prevents yarn from tangling and knotting after cutting. It incorporates a first cylinder, drive base, auxiliary clamping roller, second cylinder, connecting block, limit rod, and moving clamping roller. When the servo motor moves the cut yarn on the yarn guide roller to the leftmost position, the first cylinder activates, causing the moving and auxiliary clamping rollers to rise until the cut yarn ends are fully inside them. Then, the second cylinder moves the moving clamping roller to the right, working with the auxiliary clamping roller to clamp and secure the yarn. Finally, the first cylinder lowers the moving and auxiliary clamping rollers, straightening the cut yarn and further enhancing the device's effectiveness in preventing yarn tangling and knotting.
