DETAILED DESCRIPTION
[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0021] Please refer to Figure 1 And Figure 2This utility model provides a technical solution: a doffing machine suitable for different yarn tube sizes, including a placement seat 1, a frame 2, a drive motor 3, a cleaning guide roller 4, and a yarn tube body 5. The frame 2 is arranged on one side of the placement seat 1, and the drive motor 3 is installed on one side of the frame 2. The output end of the drive motor 3 is connected to the cleaning guide roller 4 via a coupling. The yarn tube body 5 is arranged symmetrically at the top of the placement seat 1. A rotating handwheel 6 is arranged at the top of the yarn tube body 5, and a rotating rod 7 is connected to one end of the rotating handwheel 6. The surface of the rotating rod 7 is evenly distributed... The rotating block 8 of the fabric is diamond-shaped. Limiting rods 9 are installed through both sides of the yarn tube body 5 near the rotating block 8. A fixing block 10, which is slidably connected to the limiting rods 9, is welded to the inside of the yarn tube body 5. A sliding groove 11 is provided on one side of the limiting rod 9 near the fixing block 10. Moving grooves 12 are provided on one side of the yarn tube body 5 near the limiting rod 9. A fixing plate 13 is welded to one end of the limiting rod 9. A limiting spring 14 is welded between the fixing plate 13 and the yarn tube body 5. A locking bolt 15 is threadedly connected between the yarn tube body 5 and the rotating handwheel 6.
[0022] In practice,
[0023] See Figure 1 and Figure 2 It is known that when a doffing machine is in use, it is usually not easy to place yarn tubes of different sizes, making the machine inconvenient to use. By rotating the handwheel 6, the connected rotating rod 7 can be rotated, which in turn rotates the connected rotating block 8. The rotating block 8 pushes the limiting rod 9 inside the yarn tube body 5, allowing the limiting rod 9 to slide on the surface of the fixed plate 13 on the fixed block 10. At the same time, the fixed plate 13 can compress the connected limiting spring 14 as it moves. As the limiting rod 9 continues to move, it can contact yarn tubes of different sizes, preventing rotation after the yarn tubes are connected. This allows the doffing machine to connect and place yarn tubes of different sizes, making it more convenient to use.
[0024] The bottom end of the bobbin body 5 is provided with a welded T-shaped seat 16, the inside of the placing seat 1 is provided with a displacement slot 17 near one side of the T-shaped seat 16, the end of the T-shaped seat 16 away from the bobbin body 5 is provided with symmetrically distributed plug-in blocks 18, the inside of the displacement slot 17 is provided with uniformly distributed plug-in slots 19 near one side of the plug-in blocks 18, the surface of the T-shaped seat 16 is slidably connected with a displacement plate 20, and the bottom end of the displacement plate 20 is connected with symmetrically distributed return springs 21 between the T-shaped seat 16.
[0025] In specific implementation,
[0026] As can be seen from Figure 1 , Figure 3 and Figure 4 , when the doffer is in use, it is usually not easy to adjust the position of the bobbin, so that it is more inconvenient to place the bobbin of a larger size. The bobbin body 5 can be pulled to pull the T-shaped seat 16 arranged at the bottom end, so that the T-shaped seat 16 can move the plug-in blocks 18 connected at the bottom end when moving, so that the plug-in blocks 18 can be separated from the inside of the plug-in slot 19 when moving, and the return spring 21 arranged at the bottom end of the displacement plate 20 can be extruded by the T-shaped seat 16 when moving, so that the return spring 21 can be contracted. Then the bobbin body 5 is pulled, so that the displacement plate 20 and the T-shaped seat 16 connected at the bottom end can move in the displacement slot 17, so that the position of the bobbin body 5 can be adjusted. Then the bobbin body 5 is loosened, so that the bobbin body 5 can lose the restriction of the return spring 21, so that the return spring 21 can reset, so that the T-shaped seat 16 can move downward, and the plug-in blocks 18 arranged at the bottom end can be moved, so that the plug-in blocks 18 can be relocked with the plug-in slot 19, so that the position of the bobbin body 5 can be fixed, so that the doffer can be more convenient when in use.
[0027] In summary, the doffer is mainly used in the automatic doffing process of the spinning frame. The doffer can significantly improve production efficiency, reduce the time and labor required for manual operation, and through the rotation of the rotating handle 6, the rotating handle 6 can rotate the rotating rod 7 connected thereto when rotating, so that the rotating rod 7 can push the limiting rod 9 arranged inside the bobbin body 5 through the rotating block 8, so that the limiting rod 9 can slide the fixed plate 13 connected thereto on the surface of the fixed block 10, and the fixed plate 13 can extrude the limiting spring 14 connected thereto when moving, so that as the limiting rod 9 continues to move, it can contact the bobbins of different sizes, so that the bobbins of different sizes can avoid rotating after being sleeved, so that the doffer can be used to sleeve and place bobbins of different sizes. The contents not described in detail in this description belong to the existing technology known to those skilled in the art.
[0028] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
