[0002] The yarn drawing frame is a spinning machine that processes several carded or combed yarns into yarns with certain quality requirements; the function of the drawing frame is to improve the internal structure of the yarn, thereby improving the uniformity of its long segments, while reducing the weight unevenness, making the fibers in the yarn straight and parallel, reducing hooks, making the fineness meet the requirements, and making different types or qualities of raw materials mixed evenly to achieve the specified mixing ratio.

[0003] During the operation of the drawing frame, multiple yarn lines are drawn out from the raw material barrel by the guide rollers and the guide pressure rollers, and then conveyed to the drawing frame through the feed rollers. During the yarn conveying process, the tension of the yarn may need to be adjusted according to the yarn conveying speed. However, since the distance between the existing guide pressure rollers and the feed rollers is fixed, workers are required to manually pull the yarn with the help of tools to adjust the tension, which results in poor convenience of the adjustment operation.

[0016] 1. By setting a rotating groove, a rotating shaft and a driving mechanism, when it is necessary to adjust the tension of the yarn, the driving mechanism is turned on to drive the rotating shaft to move along the arc-shaped rotating groove. Since the central axis of the arc-shaped rotating groove is parallel to the central axis of the feeding roller and the two do not overlap, when the rotating shaft moves along the rotating groove, the distance between the guide roller and the feeding roller changes, thereby changing the tension of the yarn passing through the guide roller and the feeding roller, thereby realizing the adjustment of the yarn tension, and there is no need for workers to manually pull the yarn for adjustment, thereby improving the convenience of the adjustment operation.

[0017] 2. By setting the first rotating rack, the rotating toothed disc, the pushing cylinder, etc., when it is necessary to adjust the tension of the yarn, it is only necessary to open the pushing cylinder to drive the second rotating rack to move. During the movement of the second rotating rack, the rotating toothed disc is driven to rotate, and then the arc-shaped first rotating rack is driven to rotate around the center of the circle, so that the rotating shafts on both sides drive the guide rollers to move, thereby realizing the adjustment of the tension of the yarn. During the whole process, the workers only need to operate the pushing cylinder, which is simple to operate and greatly improves the convenience of the adjustment operation.

[0018] 3. By setting up the second guide rod, the yarn passes through the second guide rod after leaving the feed roller, and then passes between the two first guide rods. Since the position of the second guide rod is higher than the position of the guide block, it avoids the bottom of the yarn from hitting the corner of the guide block when passing between the two first guide rods, causing wear of the yarn.

[0024] The utility model provides a guide frame for a yarn drawing machine, such as Figure 1 to Figure 2 As shown, it includes a frame 1, a feed roller 2 rotatably arranged on the frame 1 along a horizontal direction, and a guide strip pressing roller 3 movably arranged on the frame 1 along a direction parallel to the central axis of the feed roller 2, circular arc-shaped rotating grooves 4 are symmetrically opened on both sides of the frame 1, and a set distance is provided between the central axis of the rotating groove 4 and the central axis of the feed roller 2, and rotating shafts 5 are arranged at both ends of the guide strip pressing roller 3. The rotating shaft 5 movably passes through the rotating groove 4, and driving mechanisms 6 for driving the rotating shaft 5 to move along the rotating groove 4 are arranged on both sides of the frame 1.

[0025] Furthermore, the driving mechanism 6 includes a first arc-shaped rotating rack 6a and a fixed block 6b arranged on the inner side of the first rotating rack 6a, the central axis of the first rotating rack 6a coincides with the central axis of the rotating groove 4, the fixed block 6b is fixedly connected to the end of the rotating shaft 5, and a rotating gear plate 7 meshing with the outer wall of the first rotating rack 6a is rotatably provided on the frame 1, and a rotating member 8 for driving the rotating gear plate 7 to rotate is provided on the frame 1.

[0026] Furthermore, the rotating member 8 includes a pushing cylinder 8a arranged on the frame 1 and a second long rotating rack 8b arranged at the output end of the pushing cylinder 8a, the second rotating rack 8b is engaged with the rotating gear plate 7, and the pushing cylinder 8a can push the rotating shaft 5 to move along the rotating groove 4.

[0027] Furthermore, an arc-shaped limit block 9 is provided on the frame 1 in a direction parallel to the rotating groove 4 , and a limit groove 10 matched with the limit block 9 is provided on the first rotating rack 6 a .

[0028] Furthermore, a first fixing rod 11 is provided on the frame 1 along a direction coincident with the central axis of the rotating groove 4, a second fixing rod 12 is rotatably provided on the first fixing rod 11, and an end of the second fixing rod 12 is fixedly connected to the fixing block 6b.

[0029] Furthermore, a guide block 13 is provided on the frame 1 in a direction coinciding with the central axis of the feed roller 2, and a plurality of first guide rods 14 are evenly provided on the guide block 13 in a vertical direction, and a set distance is provided between two adjacent first guide rods 14, and the feed roller 2 is located between the guide block 13 and the guide strip pressure roller 3.

[0030] Furthermore, a second guide rod 15 is provided on the frame 1 in a direction coincident with the central axis of the feed roller 2, the second guide rod 15 is located between the feed roller 2 and the guide block 13, and the horizontal plane at the top end of the second guide rod 15 is higher than the horizontal plane at which the guide block 13 is located.

[0031] Furthermore, the second guide rod 15 is rotatably disposed on the frame 1 .

[0032] Furthermore, an elastic connecting layer 16 is provided on the outer wall of the feeding roller 2 .

[0033] Furthermore, long strip-shaped connecting grooves 17 are evenly formed on the outer wall of the elastic connecting layer 16 in a direction parallel to the central axis of the feeding roller 2 .

[0034] When it is necessary to adjust the tension of the yarn, it is only necessary to open the pushing cylinder 8a to drive the second rotating rack 8b to move. During the movement of the second rotating rack 8b, the rotating toothed disc 7 is driven to rotate, and then the arc-shaped first rotating rack 6a is driven to rotate around the center of the circle, so that the rotating shaft 5 on both sides drives the guide strip pressure roller 3 to move along the rotating groove 4. Since the central axis of the arc-shaped rotating groove 4 is parallel to the central axis of the feed roller 2 and the two do not overlap, when the rotating shaft 5 moves along the rotating groove 4, the distance between the guide strip pressure roller 3 and the feed roller 2 changes, thereby changing the tension of the yarn passing through the guide strip pressure roller 3 and the feed roller 2, thereby realizing the adjustment of the yarn tension. During the whole process, the worker only needs to operate the pushing cylinder 8a (a low-speed cylinder can be used to reduce the moving speed of the second rotating rack 8b) and observe the tension of the yarn. The operation is simple, which greatly improves the convenience of the adjustment operation.

[0035] By setting the guide block 13 and the first guide rod 14, the yarn line conveyed forward by the feed roller 2 passes between two adjacent first guide rods 14 in sequence, and then enters the drawing machine. Through the traction of the first guide rod 14, the yarn line is prevented from being entangled with each other during the process of being conveyed forward by the feed roller 2, thereby avoiding affecting the subsequent drawing operation.

[0036] By setting the second guide rod 15, the yarn passes through the second guide rod 15 after leaving the feed roller 2, and then passes between the two first guide rods 14. Since the position of the second guide rod 15 is higher than the position of the guide block 13, it is prevented that the bottom of the yarn hits the corner of the guide block 13 when passing between the two first guide rods 14, causing wear of the yarn.

[0037] By providing the limiting block 9 and the limiting groove 10, the connection between the first rotating rack 6a and the frame 1 is improved, and the movable direction of the first rotating rack 6a is restricted, thereby improving the stability of the first rotating rack 6a during movement.

[0038] By setting the first fixed rod 11 and the second fixed rod 12, when the rotating shaft 5 moves along the rotating groove 4, the rotating shaft 5 rotates around the first fixed rod 11 through the second fixed rod 12, thereby improving the connection between the rotating shaft 5 and the frame 1, making the movement process of the guide roller 3 more stable.

[0039] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
