Variable angle dividing rod

Abstract

A variable-angle yarn splitting bar is disclosed for use in the textile technology field. Yarn 1 and Yarn 2 are split at the splitting point by the splitting bar and sequentially wound onto a sizing beam via a guide roller, a take-up roller, and a tension adjusting roller. One end of a screw passes through the splitting bar and connects to a hinge. One end of a hinge is hinged to the hinge, and the other end is hinged to one end of a movable rod. The other end of the movable rod is slidably connected to the screw. When the yarns exhibit significant differences in thickness, sizing amount, and strength, resulting in numerous breakages at the splitting opening, the splitting bar of this invention can adjust the angle of the V-shaped hinge via the screw, thereby changing the opening of the yarn at the splitting point, reducing the force on the yarn in the parallel direction, reducing yarn breakage, and improving the quality of the sizing beam.

Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically a yarn splitting bar with an adjustable yarn splitting angle. Background Technology

[0002] In the sizing process of textile weaving, according to the process design requirements, after a certain number of warp beams are unwound, the yarn layers pass through two sizing pans (A and B) for sizing, pressing, and drying respectively. They are then combined in the main drying cylinder and pass through a dosing pan, where they are separated by a splitting rod to reduce adhesion. However, when the yarn quality is poor, especially with many thick and thin defects, long hairs, and a large amount of sizing, the opening at the splitting rod is often too small, causing yarn breakage at the opening, severely affecting the quality of the sizing beam. Normally, using a larger diameter splitting rod can increase the opening during separation and reduce breakage. However, each sizing machine is equipped with more than twenty splitting rods; equipping them with different diameters and specifications creates too many specifications, making management difficult and operation inconvenient. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention aims to provide a yarn splitting rod with a variable yarn splitting angle, which can easily change the angle at the yarn splitting opening, reduce yarn breakage during yarn splitting, and improve the quality of the sizing beam.

[0004] To achieve the above-mentioned objective, the present invention provides a variable yarn splitting angle splitting bar, wherein yarn one and yarn two are split by the splitting bar at the splitting point and are wound onto the sizing shaft in sequence via a yarn guide roller, a take-up roller, and a tension adjusting roller; one end of the screw passes through the splitting bar and is connected to a hinge, one end of the hinge is hinged to the hinge, and the other end is hinged to one end of a movable rod, and the other end of the movable rod is slidably connected to the screw.

[0005] Furthermore, the end of the screw that connects to the hinge has an arc structure, and the other end of the screw has a handle.

[0006] Furthermore, the screw is provided with two slides along its axial direction, and the slides are slidably connected to the pulley at one end of the movable rod.

[0007] Furthermore, the hinge and the screw joint are provided with a ball socket that matches the arc of one end of the screw.

[0008] Furthermore, the hinge has a V-shaped structure, which is the same length as the splitting rod. The movable rod opens one end of the hinge to form a trumpet-shaped structure under the action of the screw.

[0009] Furthermore, the hinge, screw, and movable rod are located on both sides of the length of the splitting rod.

[0010] Furthermore, the screw is threadedly connected to the two threaded holes of the splitting rod, and the centers of the two threaded holes of the splitting rod are on a straight line with the center of the hinge.

[0011] Compared with the prior art, when the yarn breaks frequently at the splitting opening due to differences in thickness, sizing amount, and strength, the present invention can adjust the angle of the V-shaped hinge by using a screw to change the opening of the yarn at the splitting opening, thereby reducing the force on the yarn in the parallel direction, reducing yarn breakage, and improving the quality of the sizing beam.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of protection of this invention.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this invention, a variable yarn splitting angle splitting bar is used to split yarn A and yarn B at splitting point 2 by splitting bar 3, and then wind them sequentially onto spindle 7 via yarn guide roller 4, take-up roller 5, and tension adjusting roller 6; one end of screw 11 passes through the splitting bar 3 and connects to hinge 9, one end of hinge 8 is hinged to hinge 9, and the other end is hinged to one end of movable rod 10, and the other end of movable rod 10 is slidably connected to screw 11.

[0019] Preferably, the end of the screw 11 that connects with the hinge 9 is an arc structure 12, and the other end of the screw 11 has a handle 13. The screw 11 has two slides 14 along its axial direction, and the slides 14 are slidably connected to the pulley 15 at one end of the movable rod 10. When the screw 11 is rotated to change the angle of the split opening 1, the pulley 15 at one end of the movable rod 10 can slide on the slides 14 of the screw 11, which can effectively improve the service life of the movable rod 10 and the screw 11.

[0020] Preferably, the hinge 9 and the screw 11 are provided with a ball socket 16 that matches the arc of one end of the screw 11; when the screw 11 is rotated to change the angle of the split opening 1, the ball socket 16 on the hinge 9 and the arc structure 12 on the screw 11 cooperate, which can effectively improve the service life of the hinge 9 and the screw 11.

[0021] Preferably, the hinge 8 has a V-shaped structure and the same length as the splitting rod 3. The movable rod 10 opens one end of the hinge 8 to form a flared structure under the action of the screw 11.

[0022] Preferably, the hinge 9, screw 11, and movable rod 10 are located on both sides of the length of the splitting rod 3.

[0023] Preferably, the screw 11 is threadedly connected to the two threaded holes of the twisting bar 3, and the center of the two threaded holes of the twisting bar 3 is on the same straight line as the center of the hinge 9. When the screw 11 is rotated to change the angle of the twisting opening 1, the opening of the hinge 8 can be effectively guaranteed to be symmetrical with respect to the twisting bar 3, so that yarn A and yarn B are subjected to uniform force. Figure 2 In this context, AB represents two untwisted yarns. Figure 2 In this equation, Fa is the tension force on yarn A, Fb is the tension force on yarn B, Fab is the resultant force of Fa and Fb, and Fab' is the opposite force of Fab. When the speed of the sizing machine remains constant, the tension force Fab on the yarn is constant. The larger the angle of the splitting opening 1, the larger Fa and Fb are, and the less likely the yarn is to break.

[0024] During sizing, yarns A and B can be threaded onto hinge 8. After adjusting the starting speed of the sizing machine, screw 11 can be adjusted according to the opening and breakage of yarns A and B to change the angle of the splitting opening 1. If there are many breakages in yarns A and B, the angle of the splitting opening 1 can be increased to make it larger. This will increase the tension Fa and Fb on yarns A and B, effectively reducing breakage.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
