Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile equipment, in particular to a negative pressure pipe plug Background Art
[0002] Compact spinning is a new spinning technology carried out on an improved new ring spinning frame. It reforms the drafting device of the traditional ring spinning frame, that is, a pneumatic gathering area is added in front of the original main drafting area, greatly reducing the width of the sliver band in the twisting triangle area and spinning high-quality compact ring yarns.
[0003] The pneumatic gathering area includes a negative pressure pipe, a small roller and a tensioner, and is fixed on the roller seat. Among them, both ends of the negative pressure pipe, the small roller and the tensioner are fixed and sealed by plugs, and one plug is simultaneously connected to the negative pressure pipe, the small roller and the tensioner and fixed on the roller seat. When the textile equipment runs, vibrations will occur, causing friction between the plug and the roller seat and wearing the plug. As the wear of the plug intensifies, the connection between the roller seat and the plug becomes loose. The looser the connection, the greater the vibration amplitude of the plug, and at the same time, the more serious the wear of the plug, seriously affecting the service life of the plug and the stability of the pneumatic gathering area.
[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model
[0005] Aiming at the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a negative pressure pipe plug to extend the service life and stability of the plug.
[0006] The technical solution of the present utility model is as follows:
[0007] A negative pressure pipe plug is used for sealing and connecting a negative pressure pipe, a tensioner and a small roller. The plug is provided with a first circular cavity, a mounting boss and a second circular cavity in the same direction; the diameter of the first circular cavity ≥ the diameter of the small roller; the outer contour of the mounting boss fits the inner hole surface of the negative pressure pipe; the second circular cavity is connected to the tensioner; a plane is provided on the side surface of the plug, and the plane is parallel to the axis of the first circular cavity; wherein, an elastic member is further provided on the plug, and the elastic member extends out of the plane from the side surface of the plug.
[0008] The beneficial technical effects of the present utility model are as follows:
[0009] (1) The negative pressure pipe plug in the present utility model is simultaneously connected to the negative pressure pipe, the small roller, and the tensioner. A plane is provided on the side of the plug. The plane facilitates fixing the plug on the roller seat and at the same time restricts the rotation of the plug relative to the roller seat. An elastic member is additionally provided on the plug, and the elastic member extends out of the plane. When the roller seat fixes the plug, it first contacts the elastic member. The elastic member buffers the vibration transmitted from the roller seat to the plug. And the elastic member has good deformation performance. When the plug moves relative to the roller seat, the deformation of the elastic member can offset most of the displacement, effectively reducing the wear caused by friction and extending the service life of the plug. After the elastic member is worn, only the elastic member needs to be replaced, which is convenient for maintenance and has a low maintenance cost.
[0010] (2) Further, the plug includes a first extension portion and a second extension portion provided on the plug body. The first extension portion and the second extension portion are perpendicular to the circumferential direction of the first circular cavity, that is, perpendicular to the negative pressure pipe, the small roller, and the tensioner. When installing the plug on the roller seat, the first extension portion and the second extension portion can transmit the axial thrust of the negative pressure pipe and the small roller to the roller seat. This avoids the thrust being concentrated on the plug, damaging the plug or shifting the position of the plug.
[0011] (3) Further, the card slot is a T-shaped slot, which further restricts the movement of the elastic member and increases the connection stability between the plug and the elastic member. Description of the Drawings

Figure 2 The first three-dimensional structure schematic diagram of the negative pressure pipe plug of the present utility model is shown. Please refer to Figure 1 and Figure 2 As shown in FIGS. 13, a negative pressure pipe plug is used for sealing and connecting a negative pressure pipe 6, a tensioner 8, and a small roller 7. The plug is provided with a first circular cavity 11, a mounting boss 21, and a second circular cavity 32 arranged in the same direction. The diameter of the first circular cavity 11 is ≥ the diameter of the small roller 7, and the plug is sleeved on the small roller 7 through the first circular cavity 11. The outer contour of the mounting boss 21 fits the inner hole surface of the negative pressure pipe 6 to sleeve the negative pressure pipe 6 on the mounting boss 21. The second circular cavity 32 is connected to the tensioner 8. A plane 4 is provided on the side surface of the plug, and the plane 4 is parallel to the axial direction of the first circular cavity 11. The plane 4 facilitates fixing the plug on the roller seat 5 and at the same time restricts the rotation of the plug relative to the roller seat 5. Among them, an elastic member 13 is further provided on the plug, and the elastic member 13 extends out of the plane 4 from the side surface of the plug. When the roller seat 5 fixes the plug, it first contacts the elastic member 13. The elastic member 13 buffers the vibration transmitted from the roller seat 5 to the plug. And the elastic member 13 has good deformation performance. When the plug moves relative to the roller seat 5, the deformation of the elastic member 13 can offset most of the displacement, effectively reducing the wear caused by friction and prolonging the service life of the plug. After the elastic member 13 is worn, only the elastic member 13 needs to be replaced, which is convenient for maintenance and has a low maintenance cost.
[0020] The specific structures of the first extension part 2 and the second extension part 3 are described as follows:
[0021] Please refer to Figure 1 and Figure 2 , the plug includes a plug body 1 and a first extension part 2. The first extension part 2 is arranged on the plug body 1. The first extension part 2 is perpendicular to the axis of the first circular cavity 11. The mounting boss 21 is arranged on the first extension part 2. A second extension part 3 is also arranged on the plug body 1. The second extension part 3 is perpendicular to the axis of the first circular cavity 11. The second circular cavity 32 is arranged on the second extension part 3. The first extension part 2 and the second extension part 3 are perpendicular to the circumferential direction of the first circular cavity 11, that is, perpendicular to the negative pressure tube 6, the small roller 7 and the tensioner 8. When the plug is installed on the roller seat 5, the first extension part 2 and the second extension part 3 can transfer the axial thrust of the negative pressure tube 6 and the small roller 7 to the roller seat 5. Avoiding the thrust being concentrated on the plug, damaging the plug or shifting the position of the plug.
[0022] Please refer to Figure 1 and Figure 2 , a second groove 31 is formed on the second extension part 3. The second groove 31 and the second circular cavity 32 are arranged in the same direction. The second groove 31 increases the elastic deformation ability of the second extension part 3, making it more suitable for the high-vibration environment of textile equipment.
[0023] The specific structures of the card slot 12 and the mounting boss 21 are described as follows:
[0024] Figure 3 Shows the second three-dimensional structure schematic diagram of the negative pressure tube plug of the present utility model. Please refer to Figure 1 , Figure 2 and Figure 3 , a card slot 12 is formed on the plug. The card slot 12 is formed on the plug body 1. The elastic member 13 is snapped into the card slot 12. The card slot 12 is a T-shaped groove. An elastic extension part 131 is arranged on the elastic member 13 to cooperate with the T-shaped groove. The T-shaped groove further restricts the movement of the elastic member 13, increasing the connection stability between the plug and the elastic member 13.
[0025] Please refer to Figure 3 , a screw hole 22 is arranged on the mounting boss 21. The screw hole 22 and the mounting boss 21 are arranged in the same direction. The mounting boss 21 and the negative pressure tube 6 can be fixedly connected through the screw hole 22, and the connection is stable. A third groove 23 is formed on the mounting boss 21. The third groove 23 and the mounting boss 21 are arranged in the same direction. The third groove 23 increases the elastic deformation ability of the mounting boss 21, making it more suitable for the high-vibration environment of textile equipment.
[0026] The specific structures of the second circular cavity 32, the first groove 14 and the plane 4 are described as follows:
[0027] Please refer to Figure 1 andFigure 3 On the inner wall of the second circular cavity 32, a limiting rib 33 is provided, and the limiting rib 33 is parallel to the axial direction of the second circular cavity 32. At this time, the end of the tensioner 8 can be provided with a limiting groove that cooperates with the limiting rib 33, or it can be a rectangular end with an edge. After the end of the tensioner 8 extends into the first circular cavity 11, the limiting rib 33 can limit the rotation of the tensioner 8 around the second circular cavity 32.
[0028] Please refer to Figure 1 and Figure 3 As shown in [Figure X] and [Figure Y], a first groove 14 is formed in the plug head. The first groove 14 is specifically formed in the plug head main body 1, and the first groove 14 and the first circular cavity 11 are arranged in the same direction. The first groove 14 increases the elastic deformation ability of the plug head main body 1, making it more suitable for the high-vibration environment of textile equipment. At least two planes 4 are provided on the plug head, and different planes 4 intersect. Specifically, the planes 4 are provided on the plug head main body 1, and a plurality of intersecting planes 4 are provided. The installation groove 51 of the roller seat 5 is formed in cooperation with the plurality of planes 4 to snap the plug head into the installation groove 51 and simultaneously limit the rotation of the plug head relative to the roller seat 5, enhancing the stability of the connection.
[0029] The specific working process of the present utility model is as follows:
[0030] One end of the small roller 7 is inserted into the first circular cavity 11, one end of the negative pressure pipe 6 is threadedly connected to the mounting boss 21, one end of the tensioner 8 is inserted into the second circular cavity 32, and the rotation of the tensioner 8 is restricted by the limiting rib 33. Repeat the above actions, and connect another plug head to the other ends of the small roller 7, the negative pressure pipe 6, and the tensioner 8. The two plug heads are respectively snapped into the installation groove 51 of the roller seat 5 to fix the small roller 7, the negative pressure pipe 6, and the tensioner 8. The elastic member 13 on the plug head abuts against the inner wall of the installation groove 51. When the textile equipment is working, the elastic member 13 buffers the vibration transmitted from the roller seat 5 to the plug head and offsets part of the displacement of the plug head relative to the roller seat 5 through its own deformation.
[0031] It can be seen that the above-mentioned negative pressure pipe plug head effectively reduces the wear caused by friction and prolongs the service life of the plug head. After the elastic member 13 is worn, only the elastic member 13 needs to be replaced, which is convenient for maintenance and has a low maintenance cost.
