Description

Technical Field

[0001] The invention belongs to the technical field of textile machines, and in particular relates to a yarn traction device for a textile machine. Background Art

[0002] The yarn traction device on the textile machine is one of the core components in textile production. Its function is to ensure that the yarn is transported and arranged with stable tension, speed and direction during the processing through mechanical or automated control.

[0003] The existing traction device cannot detect the thickness of the yarn during use. If a certain section of the yarn is thinner, the yarn will not meet the textile requirements or will easily break. In response to the above technical problems, the applicant has retrieved some existing technologies to solve the above problems. For example, the patent publication number CN115196411B is a yarn traction device for a textile machine. Its main technical means is that when the outer diameter of the yarn body changes significantly during the traction and transportation process, the U-shaped plate moves a large distance. At this time, the proximity switch on the fixed plate cannot sense and identify the U-shaped plate, which means that the outer diameter of the yarn body being transported is abnormal and the transportation needs to be stopped in time, thereby forming a detection and identification of the outer diameter of the yarn body during the traction and transportation process to ensure high-quality textile processing operations of the textile machine. After analysis by the applicant, the disadvantage of this technical solution is that: during the process of yarn being pulled, burrs may appear on the surface of the traction roller due to the long-term operation of the traction roller, which increases the roughness of the roller surface. This will cause the yarn to twist due to friction, that is, the yarn is slowly tightened, and the number of twists of the yarn becomes larger and larger, which will cause the yarn to gradually become thinner. At this time, the size detection of the yarn is inaccurate, and detection errors are prone to occur, which can easily affect the processing process. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] like Figure 1-Figure 5 As shown, a yarn pulling device for a textile machine includes a base plate 1, a bracket 2, a squeezing roller 14 and a detection member 17, and the device also includes:

[0038] Upper traction rollers 3 and lower traction rollers 4, two groups of upper traction rollers 3 and two groups of lower traction rollers 4 are symmetrically installed on the bracket 2, the upper traction rollers 3 and the lower traction rollers 4 are installed on the bracket 2 through a fixed rod 5, the fixed rod 5 is fixed to the bracket 2, the upper traction rollers 3 or the lower traction rollers 4 are rotatably installed on the periphery of the fixed rod 5, a driving member 11 is installed on the bracket 2, the driving member 11 is used to drive the upper traction rollers 3 and the lower traction rollers 4 to rotate, the upper traction rollers 3 and the lower traction rollers 4 have the same structure, and the yarn 10 is located between the two groups of upper traction rollers 3 and the two groups of lower traction rollers 4;

[0039] Squeezing ball 6, the outer periphery of upper traction roller 3 and lower traction roller 4 are provided with two groups of mounting holes 8, the yarn 10 is located between the two groups of mounting holes 8, and the squeezing ball 6 is rotatably mounted in the mounting holes 8;

[0040] Drive assembly 7, two sets of drive assemblies 7 are installed in the upper traction roller 3 and the lower traction roller 4, and the drive assembly 7 drives the two squeezing balls 6 to rotate. The squeezing balls 6 rotate in the direction perpendicular to the fixed rod 5. The rotation directions of the two squeezing balls 6 are opposite, and the squeezing balls 6 rotate toward the direction close to the yarn 10.

[0041] Furthermore, the driving assembly 7 includes:

[0042] The rotating rod 71 is provided with two connecting plates 51 on the periphery of the fixed rod 5, and the rotating rod 71 is rotatably mounted on the connecting plates 51;

[0043] A rotating ball 72 is fixed to the other end of the rotating rod 71. The rotating ball 72 contacts the squeezing ball 6 at the corresponding position. The rotation of the rotating ball 72 drives the squeezing ball 6 to rotate.

[0044] The conical platform 73 is sleeved on the outer periphery of the rotating rod 71. A guide block 731 is provided on the inner side of the conical platform 73. A guide groove 711 is provided on the outer periphery of the rotating rod 71. The guide block 731 is sleeved in the guide groove 711.

[0045] Elastic telescopic rods 74, a plurality of elastic telescopic rods 74 are connected between the conical platform 73 and the connecting plate 51;

[0046] Furthermore, a plurality of driving rods 75 are provided on the inner walls of the upper traction roller 3 and the lower traction roller 4 , and the driving rods 75 are used in conjunction with the conical platform 73 .

[0047] Furthermore, the driving rod 75 is elastically rotatably mounted on the inner wall of the upper traction roller 3 or the lower traction roller 4 , and the driving rod 75 rotates in a direction away from the rotating rod 71 .

[0048] When the yarn 10 is pulled along the upper and lower traction rollers 3 and the lower traction rollers 4 are pulled along, the upper and lower traction rollers 3 and the lower traction rollers 4 are rotated by the driving member 11, thereby pulling the yarn 10. When pulling, the upper and lower traction rollers 3 and the lower traction rollers 4 rotate, and the driving rod 75 squeezes the conical platform 73, so that the conical platform 73 moves downward along the rotating rod 71. The cooperation between the guide block 731 and the guide groove 711 makes the rotating rod 71 drive the rotating ball 72 to rotate. The rotation of the rotating ball 72 drives the squeezing ball 6 to rotate. When the squeezing ball 6 rotates, it drives the yarn 10 to move toward the upper and lower traction rollers 3 or the lower traction rollers 4. The two squeezing balls 6 on the same side rotate in opposite directions, so that the part of the yarn 10 in contact with the upper and lower traction rollers 3 or the lower traction rollers 4 keeps moving outward. In this way, the torsion of the yarn 10 can be effectively suppressed, thereby effectively preventing the twist number of the yarn 10 from increasing and the yarn 10 from becoming thinner, thereby ensuring that the size detection result of the yarn 10 is relatively accurate, thereby avoiding affecting the processing process as much as possible.

[0049] The two groups of squeezing balls 6 are symmetrically arranged so that the yarn 10 is evenly stressed, which can effectively avoid the accumulation of torsion caused by unilateral tension, thereby further suppressing the torsion of the yarn 10, and further effectively avoiding the twist number of the yarn 10 from increasing and the yarn 10 from becoming thinner, thereby ensuring that the size detection result of the yarn 10 is relatively accurate; in addition, the two groups of squeezing balls 6 on the left and right sides clamp the yarn 10, which can reduce the tension fluctuation of the yarn 10 and effectively avoid yarn breakage or weaving defects caused by uneven tension.

[0050] Furthermore, a plurality of protrusions 61 are provided on the periphery of the extrusion ball 6 .

[0051] In actual application of this embodiment, the plurality of protrusions 61 can increase the friction of the squeezing ball 6, so that the squeezing ball 6 can more easily drive the yarn 10 to move toward the upper traction roller 3 or the lower traction roller 4, thereby further suppressing the twisting of the yarn 10, further effectively preventing the twist number of the yarn 10 from increasing and preventing the yarn 10 from becoming thinner, thereby ensuring that the size detection result of the yarn 10 is relatively accurate, thereby avoiding affecting the processing process as much as possible;

[0052] When the protrusions 61 come into contact with the yarn 10, they will crush the surface of the yarn 10. If there is dust or impurities on the surface of the yarn 10, the crushing of the protrusions 61 can slowly separate these dust or impurities from the yarn 10, thereby improving the cleanliness of the surface of the yarn 10; at the same time, it can effectively prevent these dust or impurities from affecting the size detection results of the yarn 10, thereby further ensuring that the size detection results of the yarn 10 are relatively accurate, thereby avoiding affecting the processing process as much as possible.

[0053] like Figure 1 、 Figure 6 and Figure 7 As shown, the bracket 2 is connected to an upper annular plate 13 and two lower annular plates 18 through a support plate 12, the yarn 10 passes through the upper annular plate 13 and the two lower annular plates 18, the squeezing roller 14 and the detection member 17 are both installed on the upper annular plate 13, and the two ends of the squeezing roller 14 are respectively connected to a transmission member 15 and a transmission member 2 16, and the two lower annular plates 18 are respectively installed with a correction ring 19 and a correction ring 2 20, and the periphery of the correction ring 19 and the correction ring 2 20 are provided with a transmission ring 21, and the transmission member 15 and the transmission member 2 16 are respectively connected to the two transmission rings 21 for transmission.

[0054] Furthermore, the rotation directions of the correction ring 19 and the correction ring 2 20 are opposite.

[0055] Furthermore, a plurality of correction balls 22 are elastically mounted on the inner sides of the correction ring 1 19 and the correction ring 2 20 .

[0056] In one case of this embodiment, transmission member 15 and transmission member 2 16 both include magnetic transmission members, a main bevel gear, a slave bevel gear, a rotating shaft and gears, etc., and the transmission ring 21 can be a gear ring, and the gears and the gear rings are engaged with each other; the detection member 17 detects the distance between it and the squeezing roller 14. If the distance is large, it indicates that the size of the yarn 10 is small. If the distance is small, it indicates that the size of the yarn 10 is normal or large.

[0057] In actual application of this embodiment, since the squeezing ball 6 drives the yarn 10 to be pulled outward, this may cause the two sides of the yarn 10 to expand outward, which may easily lead to inaccurate size detection results of the yarn 10 when the size of the yarn 10 is detected; at this time, the squeezing roller 14 is driven by the yarn 10 to rotate, and the squeezing roller 14 drives the correction ring 19 and the correction ring 2 20 to rotate through the transmission member 15 and the transmission member 2 16. The rotation of the correction ring 19 and the correction ring 2 20 can smooth the surface of the yarn 10 and restore the yarn 10 to its original shape, which can effectively avoid inaccurate size detection results of the yarn 10, thereby avoiding affecting the processing process as much as possible;

[0058] The transmission member 15 and the transmission member 2 16 make the rotation directions of the correction ring 19 and the correction ring 2 20 opposite to each other, so as to prevent the correction ring 19 and the correction ring 2 20 from rotating and twisting the yarn 10. The yarn 10 remains in its original shape after the positive and negative rotations, thereby effectively preventing the twist number of the yarn 10 from increasing and preventing the yarn 10 from becoming thinner, further ensuring that the size detection result of the yarn 10 is relatively accurate.

[0059] By making the elastically mounted straightening ball 22 contact the surface of the yarn 10, the yarn 10 can be effectively prevented from twisting during the smoothing process, thereby effectively preventing the number of twists of the yarn 10 from increasing and preventing the yarn 10 from becoming thinner; in addition, this can adapt to yarns 10 of different sizes and improve practicality.

[0060] like Figure 3 As shown, a plurality of airbags 9 are provided on the inner walls of the upper traction roller 3 and the lower traction roller 4. The airbags 9 are arranged in a ring array, and the airbags 9 are located between two groups of extrusion balls 6. A connecting column 52 is provided on the periphery of the fixed rod 5, and an extrusion plate 521 is provided at the other end of the connecting column 52. The other side of the extrusion plate 521 is in an arc shape.

[0061] In actual application of this embodiment, when the upper traction roller 3 or the lower traction roller 4 rotates, the plurality of airbags 9 also rotates. When the airbags 9 move to the squeezing plate 521, the squeezing plate 521 squeezes the airbags 9, and the airbags 9 exhaust air outward through the mounting holes 8, thereby blowing dust or impurities separated from the surface of the yarn 10 away from the yarn 10, thereby further improving the cleanliness of the yarn 10; when the airbags 9 slowly move away from the squeezing plate 521, the airbags 9 slowly recover, and during this process the airbags 9 inhale air, thereby sucking dust or impurities separated from the yarn 10 into the airbags 9, thereby further improving the cleanliness of the yarn 10, thereby improving the quality of the textile;

[0062] By further cleaning away dust and impurities, it is further effectively prevented that these dust or impurities affect the size detection result of the yarn 10, further ensuring that the size detection result of the yarn 10 is relatively accurate, thereby avoiding affecting the processing process as much as possible;

[0063] When the squeezing ball 6 is in frictional contact with the yarn 10, the surface temperature of the yarn 10 will increase slightly, which may cause the yarn 10 to break when being pulled. Blowing air outward through the airbag 9 can cool the yarn 10, thereby effectively preventing the yarn 10 from breaking due to temperature when being pulled.

[0064] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
