Description

Technical Field

[0001] This utility model relates to the field of yarn post technology for textile machines, specifically a yarn post for textile machines. Background Technology

[0002] A yarn bobbin is a component on a textile machine used to hold and support the yarn bobbin. It helps the yarn to unwind evenly and smoothly from the yarn bobbin, preventing problems such as jamming, tangling, or breakage during the unwinding process. This ensures a continuous supply of yarn and improves textile quality and efficiency.

[0003] Some existing yarn post systems limit the movement of yarn bobbins by installing a threaded cap at the top. However, when encountering shorter yarn bobbins, the large gap between the bobbin and the threaded cap causes the bobbin to wobble during rotation, affecting its stability. Furthermore, some common yarn posts have a simple structure, typically a cylindrical shape. In use, the yarn bobbin is placed on the circular post, and it rotates on the post while the yarn is being pulled. However, when encountering heavier yarn bobbins, the increased friction between the bobbin and the post affects the smoothness of rotation. Jamming can easily damage or even break the yarn.

[0004] To address the aforementioned problems, we propose a yarn post for textile machines. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a yarn post for textile machines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A yarn column for a textile machine includes a column body, an mounting plate at the bottom center of the column body, a rotating cylinder at the bottom of the column body, the inner cavity of the rotating cylinder being a hollow structure, the rotating cylinder being sleeved on the outer bottom of the column body, and a limiting plate being provided at the upper outer periphery of the column body. A threaded sleeve is provided on the top of the limiting plate, and the threaded sleeve is installed on the top of the column body. The threaded sleeve and the limiting plate are connected by two sets of adjusting screws, the adjusting screws being used to adjust the height of the limiting plate.

[0008] Preferably, multiple sets of first ball bearings are embedded in the outer periphery of the bottom end of the column, and the multiple sets of first ball bearings are evenly distributed axially. Multiple sets of second ball bearings are annularly installed in the middle of the upper end of the mounting plate. When the rotating cylinder is sleeved on the bottom of the column, the inner wall of the rotating cylinder is in close contact with the first ball bearings and the bottom of the rotating cylinder is in close contact with the second ball bearings.

[0009] Preferably, the top of the column is provided with a threaded connector, and the threaded connector is threadedly connected to the threaded sleeve.

[0010] Preferably, a circular through hole is provided in the center of the inner side of the limiting plate, and the through hole passes through the threaded connector and is fitted around the periphery of the column.

[0011] Preferably, the adjusting screws are located at both ends of the inner side of the threaded sleeve and are threadedly connected to the threaded sleeve, and the bottom of the adjusting screws is movably connected to the top of the limiting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this design, the setting of the limiting plate and the adjusting screw allows the height of the limiting plate to be raised and lowered, which facilitates the staff to make the limiting plate suitable for yarn bobbins of different heights. This allows the present invention to limit the yarn bobbins of different heights and avoid the yarn bobbins being installed too loosely due to being too short, which would affect the stability during the rotation process.

[0014] In this design, the arrangement of the rotating drum, the first ball bearing, and the second ball bearing enhances the smoothness of the drum's rotation. During use, the yarn bobbin is placed on the rotating drum, and then the rotating drum is placed on the yarn post. Under the action of the first and second ball bearings, the friction between the rotating drum and the yarn post is reduced, thereby effectively preventing jamming. Attached Figure Description

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0019] Example: Refer to Figures 1-2As shown, a yarn column for a textile machine in this embodiment includes a column body 1, an mounting plate 2 at the bottom center of the column body 1, a rotating cylinder 4 at the bottom of the column body 1, the inner cavity of the rotating cylinder 4 being a hollow structure, the rotating cylinder 4 being sleeved on the outer bottom of the column body 1, and a limiting plate 8 at the upper outer periphery of the column body 1, a threaded sleeve 7 at the top of the limiting plate 8, the threaded sleeve 7 being installed on the top of the column body 1, and the threaded sleeve 7 being connected to the limiting plate 8 by two sets of adjusting screws 9, the adjusting screws 9 being used to adjust the height of the limiting plate 8.

[0020] When in use, the outer diameter of the rotating drum 4 needs to be adapted to the inner diameter of the yarn bobbin so that the yarn bobbin can be tightly fitted onto the rotating drum 4. Then the rotating drum 4 is fitted onto the column 1 for use. At this time, it is only necessary to pull the yarn on the yarn bobbin. Under the action of force, the rotating drum 4 will rotate on the column 1, thereby realizing the yarn feeding work.

[0021] Multiple sets of first ball bearings 5 ​​are embedded in the bottom periphery of the column 1. The multiple sets of first ball bearings 5 ​​are evenly distributed axially. Multiple sets of second ball bearings 6 are installed in a ring at the upper center of the mounting plate 2. When the rotating drum 4 is fitted onto the bottom of the column 1, the inner wall of the rotating drum 4 is in close contact with the first ball bearings 5 ​​and the bottom of the rotating drum 4 is in close contact with the second ball bearings 6. The first ball bearings 5 ​​can assist the inner wall of the rotating drum 4 in rolling, while the second ball bearings 6 assist the bottom of the rotating drum 4 in rolling. The rotation of the first ball bearings 5 ​​and the second ball bearings 6 can enhance the smoothness of the rotating drum 4 during rotation, reduce friction, and thus effectively prevent the yarn bobbin from jamming during rotation.

[0022] In some examples, the top of the column 1 is provided with a threaded connector 3, which is threadedly connected to the threaded sleeve 7, thereby enabling the installation and use of the limit plate 8.

[0023] In some examples, a circular through hole 10 is provided in the middle of the inner side of the limiting plate 8, and the through hole 10 passes through the threaded connector 3 and is fitted around the outer side of the column 1.

[0024] In some examples, the adjusting screws 9 are located at both ends of the inner side of the threaded sleeve 7 and are threadedly connected to the threaded sleeve 7. The bottom of the adjusting screw 9 is movably connected to the top of the limiting plate 8. By rotating the adjusting screw 9, the limiting plate 8 can be adjusted to rise or fall, thereby limiting yarn bobbins of different heights. During adjustment, a gap needs to be left between the limiting plate 8 and the yarn bobbin to avoid excessive clamping of the yarn bobbin, which would affect the stability of the yarn bobbin during rotation.

[0025] The working principle of this utility model is as follows:

[0026] During use, the operator needs to select a suitable rotating drum 4 according to the diameter of the yarn spool. First, the operator needs to fit the yarn spool tightly onto the rotating drum 4. Then, the rotating drum 4 is fitted onto the column 1. When the rotating drum 4 is installed, its inner wall will make contact with the first ball bearing 5. This allows the yarn spool to rotate on the column 1 under the action of the first ball bearing 5 when the yarn is pulled, thereby improving the smoothness of the rotation of the rotating drum 4 and preventing the yarn spool from jamming due to excessive friction during rotation. If the yarn is jammed, forcibly pulling it may cause it to break.

[0027] Additionally, during installation, the threaded sleeve 7 needs to be threaded onto the threaded connector 3 at the top of the column 1. At this time, the limiting plate 8 is located at the top of the yarn bobbin, thus limiting the top of the yarn bobbin and preventing it from falling off the column 1 during rotation. By rotating the two sets of adjusting screws 9, the height of the limiting plate 8 can be adjusted, allowing workers to adapt the limiting to yarn bobbins of different heights. When encountering a taller yarn bobbin, the adjusting screws 9 need to be rotated in the opposite direction to raise the limiting plate 8. When encountering a shorter yarn bobbin, the adjusting screws 9 need to be rotated in the forward direction to lower the limiting plate 8. A gap needs to be left between the limiting plate 8 and the yarn bobbin to prevent the limiting plate 8 from clamping the yarn bobbin and to prevent the yarn bobbin from being too loose on the yarn column due to the lack of a limiting measure above it, which would affect the stability during rotation. The limiting plate 8 mainly serves to limit the yarn bobbin and prevent it from falling off the top of the column 1.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
