A device for adjusting the upper and lower air loops of a two-for-one twister

Abstract

This utility model relates to the field of twisting machine technology, specifically to an adjustable air ring device for a twisting machine. It includes a base and a drive motor mounted on the base. The output end of the drive motor has a threaded rod, on which a traction plate is threadedly mounted. The lower end of the threaded rod passes through the base. In use, when the upper mounting plate rises, the lower mounting plate moves towards the spindle shaft of the twisting machine. At this time, the air ring rises, the yarn path becomes longer, and the damping block gradually increases its resistance to the spindle shaft, causing the spindle shaft speed to decrease and preventing over-twisting. Conversely, when the upper mounting plate falls, the lower mounting plate moves away from the spindle shaft. At this time, when the air ring falls, the yarn path becomes shorter, and the damping block gradually decreases its resistance to the spindle shaft, causing the spindle shaft speed to increase, thereby maintaining the uniformity of twisting.

Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and in particular to an adjustable device for the air ring of a twisting machine. Background Technology

[0002] The aerodynamic shape formed when yarn is twisted is called an air ring. It needs to be kept stable during the twisting process. The height and shape of the air ring directly affect the twisting effect of the yarn. Therefore, it is necessary to adjust the height of the air ring in a timely manner. Existing technology involves rotating a threaded rod when the air ring needs to be adjusted. The rotation of the threaded rod drives the support rod to move. The movement of the support rod simultaneously drives multiple linkage frames to rise or fall.

[0003] For example, Chinese patent application number CN 202220381343.7 discloses a twisting machine air ring adjustment device, including a base. A processing frame is fixedly connected to the top of the base. A sliding plate is fixedly connected to the right side of the inner cavity of the processing frame. A slider is slidably connected inside the sliding plate. A support rod is fixedly connected to the left side of the slider. A threaded rod is rotatably connected to the left side of the top of the base via a bearing. When the air ring needs to be adjusted, rotating the threaded rod drives the support rod to move. The movement of the support rod simultaneously drives multiple linkage frames to rise or fall, thus achieving the effect of simultaneously raising or lowering all T-shaped wire hook mounting seats. However, in actual use, simply raising or lowering the linkage frames cannot achieve the ideal twisting effect. That is, when the air ring rises, the yarn running path becomes longer, resulting in over-twisting; when the air ring falls, the yarn path becomes shorter, resulting in poor twisting uniformity. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an adjustable device for the air ring of a twisting machine, so as to solve the technical problem that the existing technology can not achieve the ideal twisting effect by only raising or lowering the linkage frame. That is, when the air ring is raised, the yarn running path becomes longer and there is over-twisting, while when the air ring is lowered, the yarn path becomes shorter and there is poor twisting uniformity.

[0005] To achieve the above objectives, this utility model provides an adjustable device for the air ring of a twisting machine, including a base and a drive motor mounted on the base. The output end of the drive motor is provided with a threaded rod, and a traction plate is threaded onto the threaded rod. The lower end of the threaded rod passes through the base. The adjustable device further includes: An upper mounting plate is provided on the side end of the traction plate, and an adjustable air ring is provided inside the upper mounting plate; A gear coaxially located at the lower end of the threaded rod; A rack is slidably disposed within the opening area, and the rack meshes with the gear; A lower mounting plate is provided at the end of the rack, and a damping block is provided on the lower mounting plate to cooperate with the spindle shaft of the twisting machine; Adjustment part for adjusting the gas ring; The connecting part used to install the damping block.

[0006] Furthermore, the middle part of the base is an opening area, the lower end of the threaded rod passes through the base and extends to the opening area, and the gear and rack are both placed in the opening area.

[0007] Furthermore, the adjustment unit includes: The upper mounting plate has a yarn guide hole and a sliding groove, and the air ring is placed in the yarn guide hole; An L-shaped push-pull plate is provided on the side end of the gas ring, the L-shaped push-pull plate is slidably disposed in the slide groove, and the upper end of the L-shaped push-pull plate extends out of the slide groove; A locking bolt is threaded onto the upper mounting plate, and the end of the locking bolt abuts against the L-shaped push-pull plate.

[0008] Furthermore, the traction plate is evenly distributed with several upper mounting plates, and the height of the several upper mounting plates is consistent.

[0009] Furthermore, the connecting portion includes: A bent plate is provided on the lower mounting plate; A sliding column is slidably disposed on the bending plate, and the back of the damping block is fixedly connected to the sliding column; A spring is fitted onto the sliding column, with one end of the spring abutting against the damping block and the other end of the spring abutting against the bending plate.

[0010] Furthermore, the lower mounting plate is evenly distributed with a plurality of bending plates, and the height of the plurality of bending plates is consistent.

[0011] Furthermore, the end face of the damping block is an arc-shaped surface, and in the horizontal direction, the damping block cooperates with the spindle shaft of the twisting machine.

[0012] Furthermore, the base is provided with a guide rod, the upper end of which is fixedly connected to the upper mounting plate, and the guide rod is positioned to the side of the rack in the vertical direction.

[0013] The beneficial effects of this utility model are as follows: When the upper mounting plate rises, the lower mounting plate moves towards the spindle shaft of the twisting machine. At this time, the air ring rises, the yarn running path becomes longer, and the damping block gradually strengthens its resistance to the spindle shaft of the twisting machine, thereby reducing the spindle shaft speed and preventing over-twisting. When the upper mounting plate falls, the lower mounting plate moves away from the spindle shaft of the twisting machine. At this time, the air ring falls, the yarn path becomes shorter, and the damping block gradually reduces its resistance to the spindle shaft of the twisting machine, thereby increasing the spindle shaft speed and maintaining the uniformity of twisting.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] The first aspect of this utility model proposes an adjustable device for the air ring of a doubling twister, such as... Figure 1-5 As shown, the device includes a base 1 and a drive motor 2 mounted on the base 1. The output end of the drive motor 2 is provided with a threaded rod 3, and a traction plate 4 is threaded onto the threaded rod 3. The lower end of the threaded rod 3 passes through the base 1. The adjustable device also includes: An upper mounting plate 5 is located on the side end of the traction plate 4, and an adjustable air ring 6 is provided inside the upper mounting plate 5; Gear 7 is coaxially located at the lower end of threaded rod 3; A rack 8 is slidably disposed in the opening area, and the rack 8 meshes with the gear 7; A lower mounting plate 9 is provided at the end of the rack 8, and a damping block 10 is provided on the lower mounting plate 9 to cooperate with the spindle shaft of the twisting machine; Adjustment part used to adjust the gas ring 6; The connecting part for installing the damping block 10.

[0020] In this embodiment, during use, the output end of the drive motor 2 drives the threaded rod 3 to rotate on the base 1, thereby driving the traction plate 4 to perform corresponding rising or falling actions. The upper mounting plate 5 is located on the side end of the traction plate 4, so the synchronous lifting and lowering action of the air ring 6 set in the upper mounting plate 5 can be adjusted. The adjustment part can also effectively adjust the air ring 6 in the horizontal direction. Simultaneously, driven by the threaded rod 3, the lower mounting plate 9 moves horizontally via the gear 7 and its meshing rack 8. The lower mounting plate 9, through the connecting part, drives the damping block 10 to move synchronously. That is, when the upper mounting plate 5 rises, the lower mounting plate 9 moves closer to the spindle shaft of the twisting machine. At this time, the air ring rises, the yarn running path becomes longer, and the damping block 10 gradually strengthens the resistance applied to the spindle shaft of the twisting machine, causing the spindle shaft speed to decrease and preventing over-twisting. When the upper mounting plate 5 falls, the lower mounting plate 9 moves away from the spindle shaft of the twisting machine. At this time, the air ring falls, the yarn path becomes shorter, and the damping block 10 gradually reduces the resistance applied to the spindle shaft of the twisting machine, causing the spindle shaft speed to increase, thereby maintaining the uniformity of twisting.

[0021] In this embodiment, as Figure 1 , Figure 4 As shown, the middle part of the base 1 is an open area, the lower end of the threaded rod 3 passes through the base 1 and extends to the open area, and the gear 7 and rack 8 are both placed in the open area.

[0022] In this embodiment, as Figure 1 , Figure 2 As shown, the adjustment unit includes: A yarn guide hole 11 and a slide groove 12 are provided in the upper mounting plate 5, and the air ring 6 is placed in the yarn guide hole 11; An L-shaped push-pull plate 13 is provided on the side end of the gas ring 6. The L-shaped push-pull plate 13 is slidably disposed in the slide groove 12, and the upper end of the L-shaped push-pull plate 13 extends out of the slide groove 12. The locking bolt is threaded onto the upper mounting plate 5. The end of the locking bolt abuts against the L-shaped push-pull plate 13. By tightening or loosening the locking bolt, the installation position of the air ring 6 in the yarn guide hole 11 can be adjusted via the L-shaped push-pull plate 13.

[0023] In this embodiment, as Figure 1 As shown, several upper mounting plates 5 are evenly distributed on the traction plate 4. The height of the several upper mounting plates 5 is consistent, which is suitable for twisting operations of large batches of textile yarn.

[0024] In this embodiment, as Figure 3 As shown, the connecting part includes: The bent plate 14 is installed on the lower mounting plate 9; The sliding column 15 is slidably mounted on the bending plate 14, and the back of the damping block 10 is fixedly connected to the sliding column 15. A spring 16 is fitted on the slide column 15. One end of the spring 16 abuts against the damping block 10, and the other end of the spring 16 abuts against the bending plate 14. Under the action of the spring 16's own elastic force, the damping block 10 can stably and continuously apply gradually increasing or decreasing resistance to the spindle shaft of the twisting machine, so as to avoid sudden changes in the spindle shaft speed of the twisting machine.

[0025] In this embodiment, as Figure 1 As shown, several bending plates 14 are evenly distributed on the lower mounting plate 9. The height of the bending plates 14 is consistent, which is suitable for twisting operations of large batches of textile yarns.

[0026] In this embodiment, as Figure 3 As shown, the end face of the damping block 10 is an arc-shaped surface. In the horizontal direction, the damping block 10 cooperates with the spindle shaft of the twisting machine to further ensure the stability of the applied resistance.

[0027] In this embodiment, as Figure 5 As shown, a guide rod 17 is provided on the base 1. The upper end of the guide rod 17 is fixedly connected to the upper mounting plate 5. In the vertical direction, the guide rod 17 is placed on the side of the rack 8 to ensure the stability of the upper mounting plate 5 during lifting and lowering.
