Description
Technical Field
[0001] The present application relates to the field of weaving technology, and in particular to a thread-releasing mechanism for a loom. Background Art
[0002] A loom is a mechanism for weaving silk threads into cloth. During the weaving process of the loom, the silk threads need to be unwound from the bobbins for use by the loom.

The bobbin is sleeved on the wire-paying post, the connecting portion is connected to the frame, and the limiting portion is supported on the lower end of the bobbin.
[0007] By adopting the above technical solution, the wire drum can be suspended above the frame with the cooperation of the wire-releasing column, the connecting part and the limiting part, which effectively avoids the interference of the wire with the frame during the unwinding process and improves the wire-releasing efficiency.
[0008] In a specific implementation manner, the diameter of the limiting portion is greater than the diameter of the bobbin.

[0014] In a specific possible implementation, a limiting rod is provided on the side of the wire-paying column, and the limiting rod is arranged to be retractable along the radial direction of the wire-paying column, and a second limiting groove for accommodating the limiting rod is circumferentially opened on the inner wall of the wire barrel.
[0015] By adopting the above technical solution, not only the wire-releasing stability of the bobbin can be improved, but also the rotation of the bobbin will not be affected.
[0016] In a specific possible implementation manner, there are a plurality of the limiting rods, and the plurality of limiting rods are arranged at intervals around the circumference of the pay-off column.
[0017] In a specific possible implementation scheme, a mounting groove is provided on the side of the wire-releasing column, a spring is provided in the mounting groove, and the limiting rod is inserted into the mounting groove and connected to the spring.
[0018] By adopting the above technical solution, the limiting rod can contact the bottom of the second limiting groove under the action of the spring, which effectively improves the limiting effect of the limiting rod on the wire reel.
[0019] In a specific possible implementation manner, the connecting portion includes a connecting column detachably connected to the upper end of the pay-off column, and a connecting hook provided on the connecting column, and the connecting hook is hooked on the frame.
[0020] By adopting the above technical solution, the disassembly and assembly of the pay-off module on the rack is greatly facilitated, and the pay-off efficiency is improved.
[0021] In a specific possible implementation scheme, a pay-off rod is arranged on the upper part of the frame along the horizontal direction, a third limiting groove is arranged on the upper ring of the pay-off rod, and the connecting hook is embedded in the third limiting groove.
[0022] By adopting the above technical solution, the pay-off module is effectively prevented from moving relative to the pay-off rod during the pay-off process of the bobbin.
[0023] In a specific possible implementation manner, the plurality of pay-off modules are arranged at intervals along the length direction of the pay-off rod.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.
[0031] See also Figure 1-2 As shown, a wire-releasing mechanism for a loom is shown, which is arranged on the frame 3 of the loom and is used to unwind the silk thread on the bobbin 4. It includes a plurality of wire-releasing modules 1 suspended on the frame 3, and each wire-releasing module 1 includes a wire-releasing column 11 extending in the vertical direction, a connecting portion 12 arranged at the upper end of the wire-releasing column 11, and a limiting portion 13 arranged at the lower end of the wire-releasing column 11. The bobbin 4 is sleeved on the wire-releasing column 11, the connecting portion 12 is connected to the frame 3, and the limiting portion 13 is supported at the lower end of the bobbin 4. Among them, the limiting portion 13 is threadedly connected to the lower end of the wire-releasing column 11, and the connecting portion 12 is threadedly connected to the upper end of the wire-releasing column 11.
[0032] When in use, the wire reel 4 is sleeved on the wire pay-off column 11, and then the wire on the wire reel 4 is reeled downward. Since the wire pay-off module 1 is suspended on the frame 3, the wire will not interfere with the frame 3 during the downward reeling process, thereby improving the wire pay-off efficiency.
[0033] In this embodiment, the diameter of the limiting portion 13 is greater than the diameter of the bobbin 4. The limiting portion 13 includes a limiting plate 131 and a first limiting groove 132 coaxially provided on the limiting plate 131. The lower end of the bobbin 4 is coaxially embedded in the first limiting groove 132.
[0034] When the wire drum 4 is sleeved on the mounting column, the lower end of the wire drum 4 can be just embedded in the first limiting groove 132. The first limiting groove 132 can limit the wire drum 4 to prevent the wire drum 4 from shaking during the wire-releasing process, thereby effectively improving the wire-releasing stability of the wire drum 4.
[0035] In this embodiment, a mounting groove 112 is provided on the side of the wire-paying column 11, a spring 113 and a limiting rod 111 are provided in the mounting groove 112, two ends of the spring 113 are respectively connected to the groove bottom of the mounting groove 112 and the limiting rod 111, the limiting rod 111 is retractable along the radial direction of the wire-paying column 11 under the action of the spring 113, and a second limiting groove 41 for accommodating the limiting rod 111 is provided circumferentially on the inner wall of the wire drum 4. There are multiple limiting rods 111, and the multiple limiting rods 111 are arranged at intervals around the circumference of the wire-paying column 11.
[0036] When the wire reel 4 is put onto the wire-releasing column 11, the limiting rod 111 is squeezed by the inner wall of the wire reel 4, and then when the limiting rod 111 reaches the second limiting groove 41, it contacts the bottom of the second limiting groove 41 under the elastic force of the spring 113, which can further prevent the wire reel 4 from shaking during the wire-releasing process, and the limiting rod 111 can rotate relative to the second limiting groove 41, which will not affect the rotation and wire-releasing of the wire reel 4.
[0037] In this embodiment, a pay-off rod 2 is arranged horizontally on the upper part of the frame 3, a third limiting groove 21 is arranged on the pay-off rod 2, and the connecting portion 12 includes a connecting column 121 detachably connected to the upper end of the pay-off column 11, and a connecting hook 122 arranged on the connecting column 121, and the connecting hook 122 is embedded in the third limiting groove 21. The third limiting groove 21 can limit the connecting hook 122, effectively preventing the pay-off module 1 from moving relative to the pay-off rod 2 during the pay-off process of the bobbin 4.
[0038] Among them, a plurality of pay-off modules 1 are arranged at intervals along the length direction of the pay-off rod 2 .
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
