Description

Technical Field

[0001] This utility model relates to the field of ring spinning machine technology, and in particular to a ring spinning machine drafting improvement device. Background Technology

[0002] The spinning frame is a key piece of equipment in the textile industry used to stretch spun fibers into fine yarn. Its drafting unit, as the core component of the spinning frame, plays a crucial role in improving yarn quality and production efficiency. The main function of the drafting unit is to adjust the degree of fiber stretching by applying tension and controlling the stretch ratio, thereby affecting the yarn's strength, elongation, and other physical properties.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an improved drafting device for a spinning frame, comprising:

[0034] The support seat 1 is equipped with a yarn drafting mechanism. It should be noted that this mechanism facilitates the drafting of the yarn and allows for the easy removal and cleaning of the upper drafting roller 3 and the lower drafting roller 5. This convenient operation ensures the effectiveness of subsequent drafting.

[0035] The drafting mechanism of the spinning frame includes a connecting frame 1 2, an upper drafting roller 3, a connecting frame 2 4, a lower drafting roller 5, a connecting seat 6, a threaded cylinder 7, a servo motor 8, a lead screw 9, a plate 1 10, a plate 2 11, a side seat 12, and a locking block 13.

[0036] The upper drafting roller 3 is rotatably mounted on the connecting frame 1 2, and the lower drafting roller 5 is rotatably mounted on the connecting frame 2 4. It should be noted that the fine yarn is drafted through the upper drafting roller 3 and the lower drafting roller 5.

[0037] The connecting seat 6 is fixedly installed at the bottom of the connecting frame 2 4. The threaded cylinder 7 and the plate 1 10 are both fixedly installed at the bottom of the connecting seat 6. The servo motor 8 is fixedly installed at the bottom of the bearing seat 1. The output end of the servo motor 8 is fixedly connected to the lead screw 9. The lead screw 9 is threadedly connected to the threaded cylinder 7. The plate 2 11 is fixedly installed at the top of the bearing seat 1. The plate 1 10 is sleeved on the outer side of the plate 2 11. The side seat 12 is fixedly installed on the connecting frame 2. The snap-fit ​​block 13 is fixedly connected to the plate 1 10. The snap-fit ​​block 13 is snapped into the side seat 12.

[0038] With the above structure, starting the servo motor 8 causes the lead screw 9 to rotate, which in turn causes the threaded cylinder 7 to move the connecting seat 6, thus moving the lower drafting roller 5. This allows for adjustment of the distance between the lower drafting roller 5 and the upper drafting roller 3, facilitating the drafting process of the fine yarn. When it is necessary to remove the upper and lower drafting rollers 3 and 5 for cleaning, starting the servo motor 8 causes the connecting seat 6 to move downwards, which in turn causes the plate 10 to move downwards, allowing the locking block 13 to move out of the side seat 12. At this point, the connecting frame 2 is pulled horizontally to remove it. Then, starting the servo motor 8 causes the connecting seat 6 to move upwards until the lead screw 9 unscrews from the threaded cylinder 7, separating the plate 10 from the plate 2 11. The connecting frame 2 can then be removed. This facilitates the removal of the upper and lower drafting rollers 3 and 5 for cleaning, ensuring convenient operation and guaranteeing the subsequent drafting effect.

[0039] Specifically, the drafting mechanism of the spinning machine also includes a docking block 15, the side of which is fixedly connected to the plate 11, and the docking block 15 is clamped to the connecting frame 2.

[0040] The above structure allows for the limiting of the connecting frame 2.

[0041] Specifically, a spinning machine assembly base 17 is fixedly installed at the bottom of the bearing base 1. The spinning machine assembly base 17 has assembly holes. It should be noted that the spinning machine assembly base 17 is fixed in the designated position by bolts.

[0042] Specifically, the connecting frame 12 has a docking groove 16 on its side, and the docking block 15 is engaged with the docking groove 16. The side seat 12 has a snap-fit ​​hole 14 on its top, and the snap-fit ​​block 13 is engaged with the snap-fit ​​hole 14. The snap-fit ​​hole 14 has a T-shaped structure, which is convenient for docking.

[0043] Specifically, the inner side of connecting frame 2 4 is in contact with the inner side of connecting frame 1 2, and the bottom of connecting frame 1 2 is in contact with the bearing seat 1. It should be noted that connecting frame 1 2 is supported.

[0044] Specifically, a square hole is provided at the bottom of plate 10, and plate 2 11 is in contact with the inner wall of the square hole. It should be noted that this facilitates the vertical movement of plate 10 and can guide plate 10.

[0045] Working principle:

[0046] S1: When it is necessary to draft the fine yarn, start the servo motor 8 fixedly installed at the bottom of the support seat 1. The output end of the servo motor 8 is fixedly connected to the lead screw 9. The motor rotates and drives the lead screw 9 to rotate synchronously. Since the lead screw 9 is threadedly connected to the threaded cylinder 7 fixedly installed at the bottom of the connecting seat 6, the rotation of the lead screw 9 will cause the threaded cylinder 7 to drive the connecting seat 6 to move vertically. The top of the connecting seat 6 is fixedly connected to the connecting frame 2 4. Therefore, the connecting frame 2 4 will move together with the connecting seat 6, thereby driving the lower drafting roller 5 rotatably installed on the connecting frame 2 4 to move. At the same time, the plate 10 fixed at the bottom of the connecting seat 6 is sleeved on the outside of the plate 2 11 fixed at the top of the support seat 1. The cooperation between the plate 10 and the plate 2 11 provides guidance for the movement of the connecting seat 6, ensuring that the lower drafting roller 5 moves smoothly. By adjusting the distance between the lower drafting roller 5 and the upper drafting roller 3 rotatably installed on the connecting frame 1 2, the drafting requirements of different fine yarns can be adapted to achieve precise drafting of the fine yarn.

[0047] S2: When it is necessary to clean the upper drawing roller 3, start the servo motor 8 and control the screw 9 to rotate in the opposite direction, so that the threaded cylinder 7 drives the connecting seat 6 to move down. When the connecting seat 6 moves down, the plate 10 moves down synchronously. The snap-fit ​​block 13 fixed on the plate 10 moves down accordingly and gradually comes out from the T-shaped snap-fit ​​hole 14 opened at the top of the upper side seat 12 of the connecting frame 12, releasing the snap-fit ​​limit on the connecting frame 12. At this time, pull the connecting frame 12 horizontally to separate the side docking groove 16 of the connecting frame 12 from the docking block 15 on the plate 2. The connecting frame 12 and the upper drawing roller 3 can be removed together for easy cleaning.

[0048] S3: After the upper drawing roller 3 is removed, the connecting seat 6 continues to move upward through the servo motor 8 until the screw 9 is completely unscrewed from the threaded cylinder 7 and the plate body 10 and plate body 2 11 are separated. At this time, the connecting frame 2 4 loses its constraint and the connecting frame 2 4 and the lower drawing roller 5 can be directly removed for cleaning.

[0049] S4: After cleaning, assemble in reverse order. First, put the plate 10 on the connecting seat 6 corresponding to the connecting bracket 2 4 onto the plate 11, and rotate the screw 9 to connect with the threaded cylinder 7. Then, snap the docking groove 16 of the connecting bracket 2 with the docking block 15, control the connecting seat 6 to move upward so that the snapping block 13 snaps into the snapping hole 14, complete the assembly, and restore the stretching function.

[0050] The above provides a detailed description of the improved drafting device for a spinning frame provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
