Description

Technical Field

[0001] This application relates to the field of circular loom technology, and more specifically, to a shuttle anti-drop device. Background Technology

[0002] Circular looms are widely used equipment in the weaving industry. Circular looms use shuttles to carry the weft yarns through the warp yarns, thus weaving fabric.

[0003] In a related technology, a shuttle for a circular loom includes a base plate with two support seats on the base plate and a support rod between the two support seats. A clamping device for holding the weft yarn tube is slidably mounted on the support rod. However, the weft yarn tube is difficult to install, requiring considerable force. After installation, without a fixing mechanism, the weft yarn tube will become inconsistently tight and loose, easily causing inaccurate weft insertion and increasing the risk of weft slippage. Furthermore, the weft yarn tubes vary in length, making it difficult for the clamping device to meet the clamping requirements of different weft yarn tube styles. Therefore, there is an urgent need for a shuttle anti-drop device to solve the above problems. Utility Model Content

It should be noted that the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0026] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of this application may have fewer components, other components not shown in the drawings, different components, differently arranged components, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0027] See attached document Figure 1-6This application discloses a shuttle anti-drop device, comprising a base 1, support frames 2 on both sides of the base 1, and clamps symmetrically arranged above the support frames 2. At least one side of the clamp is a retractable clamp 3. In this embodiment, the left clamp is a retractable clamp 3. The support frames 2 are provided with threaded holes 9. The retractable clamp 3 includes a connecting rod 4, a first telescopic spring 5, a movable piece 6, and a boss 8. The connecting rod 4 cooperates with the threaded hole 9. The movable piece 6 has a first through hole in its center, and the boss 8 has a second through hole in its center. The connecting rod 4 has the same diameter as the first through hole and the second through hole. The boss 8 is rotatably engaged with the movable piece 6. One side of the movable piece 6 is fixedly connected to the first telescopic spring 5. The connecting rod 4 passes through the first telescopic spring 5, the movable piece 6 and the boss 8 in sequence. The right clamp adopts a conventional rotating setting, specifically including the second connecting rod 4, the second movable piece 6 and the second boss 8. The second movable piece 6 is rotatably engaged with the second boss 8. The second connecting rod 4 is fixedly connected to the right support frame 2. The weft tube is placed between the boss 8 and the second boss 8.

[0028] In another embodiment of this application, the clamps above the support frame 2 are all retractable clamps 3.

[0029] The anti-drop device also includes a limiting device 10, which includes an L-shaped connecting rod 11, an L-shaped fixing rod 12, an L-shaped rotating rod 13, and a second telescopic spring 14. The L-shaped connecting rod 11 cooperates with the connecting rod 4. One side of the L-shaped fixing rod 12 is fixed to the L-shaped connecting rod 11. One side of the L-shaped rotating rod 13 is rotatably connected to the L-shaped fixing rod 12. The two ends of the second telescopic spring 14 are respectively fixed to the L-shaped fixing rod 12 and the L-shaped rotating rod 13. The L-shaped rotating rod 13 is rotatably set. When the weft tube is placed into the clamp, the L-shaped rotating rod 13 is lifted counterclockwise. After the weft tube is placed in, the L-shaped rotating rod 13 is released, and the end of the L-shaped rotating rod 13 abuts against the moving piece 6.

[0030] Specifically, the end of the L-shaped rotating rod 13 extends toward the first telescopic spring 5, see Appendix Figure 5 , 6 The L-shaped rotating rod 13 has a certain length at its end, which facilitates the contact between the end of the L-shaped rotating rod 13 and the moving piece 6.

[0031] The base 1 is provided with a fixing hole 15, which is fixed to the workbench below by bolts.

[0032] Specifically, the connecting rod 4 has an external thread 16 on the side near the threaded hole 9. The connecting rod 4 and the threaded hole 9 are threaded together. The depth of the connecting rod 4 extending into the threaded hole 9 can be adjusted by the external thread 16 on one side of the connecting rod 4, and the connecting rod 4 can be fixed.

[0033] Specifically, a limiting block is provided at the end of the connecting rod 4 near the boss 8. The connecting rod 4 has a certain length, and the limiting block at the end of the connecting rod 4 is used to limit the displacement of the boss 8.

[0034] Specifically, the boss 8 is a frustum-shaped structure. The diameter of the bottom surface of the boss 8 near the moving piece 6 is larger than the diameter of the top surface of the boss 8 away from the moving piece 6. The boss 8 is used to cooperate with the tube body of the weft tube to facilitate the placement of the weft tube between the clamps.

[0035] The base 1 is made of stainless steel.

[0036] The connecting rod 4 has a retaining ring 17 on the side near the L-shaped connecting rod 11. The retaining ring 17 is detachable, and its right side engages with the first telescopic spring 5. When the first telescopic spring 5 is in contact with the retaining ring 17, the retaining ring 17 improves the stability of the connecting rod 4 and the L-shaped connecting rod 11, preventing them from moving and thus improving the stability of the device.

[0037] Specifically, the support frame 2 has a reinforcing rib 18 on one side.

[0038] The anti-drop device also includes a shim, and there are several shims. The shims are detachably installed between the L-shaped connecting rod 11 and the support frame 2. The shims are used to adjust the distance between the L-shaped connecting rod 11 and the support frame 2. The length of the first telescopic spring 5 can also be changed, which can adjust the extension length of the connecting rod 4 and the push-out length of the end of the L-shaped rotating rod 13, and the fine adjustment effect is better.

[0039] In use, the base 1 is fixed to the lower workbench with bolts. The gasket, fixing ring 17, and limiting device 10 are fitted onto the connecting rod 4. The connecting rod 4 is fixed to the threaded hole 9, and its extension length is determined. After fixing, the weft tube is inserted between the clamps from one side of the telescopic clamp 3. The telescopic clamp 3 is detachable. The connecting rod 4 has a certain length; by adjusting the length of the connecting rod 4 extending into the threaded hole 9, the distance between the clamps can be adjusted to meet the fixing needs of different styles of weft tubes. The gasket is used to adjust the distance between the L-shaped connecting rod 11 and the support frame 2, thereby adjusting the extension length of the connecting rod 4 and the push-out length of the end of the L-shaped rotating rod 13, resulting in better fine-tuning. The first telescopic spring 5 of the telescopic clamp 3 facilitates the installation of the weft tube. The L-shaped rotating rod 13 of the limiting device 10 restricts the movement of the moving piece 6, preventing displacement of the weft tube. The device has a simple structure.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art, all of which fall within the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
