Technical Field

[0002] The current bag body is mainly woven by circular looms. It is known that circular looms are mainly woven by rotating textile shuttles. The current circular looms have major defects. The current weft threads are clamped on the textile shuttles by means of drums, and the bag body is woven by the rotation of the textile shuttles. However, a problem arises in the process of bag body weaving, that is, when the weft threads are woven, the weft threads will break when the textile shuttles rotate rapidly, which requires timely observation by manual personnel, otherwise the gaps between the weft threads of the bag body will be relatively large, and the bag bodies produced in this way will be defective. The above-mentioned weft breakage and weft completion are both error corrections; at the same time, when weaving, due to the rapid unwinding of the weft threads on the textile shuttles, the drums are replaced before the unwinding of the weft threads is completed, but one staff member needs to manage multiple circular looms, so that the unwinding textile shuttles cannot be found in time. When they are not replaced in time, the gaps between the weft threads will increase, and the bag bodies produced in this way will be defective. Summary of the invention

[0017] Now in conjunction with the accompanying drawings, the utility model is further explained.

[0018] like Figure 1-5 As shown, a textile shuttle for intelligent error correction of a circular loom comprises a shuttle body 1, a drum clamping mechanism 2, a thread breakage detection mechanism 14 and an unwinding detection mechanism 15. The present application only improves the drum clamping mechanism 2 of the shuttle body, and the other structures of the shuttle body are consistent with a textile shuttle for ensuring the warp density of a bag body previously applied for by the present applicant, with application number 202220435932.9, wherein a drum clamping mechanism 2 is installed on the shuttle body 1, and the left and right ends of a weft drum 20 wound with weft thread are clamped by the drum clamping mechanism 2, and an unwinding detection mechanism 15 is installed at the right end of the drum clamping mechanism 2, and a thread breakage detection mechanism 14 is installed on the shuttle body 1 and is located on the right side of the drum clamping mechanism 2, and the unwinding detection mechanism 15 is used to monitor whether the weft thread on the drum 20 has been unwound, and the thread breakage detection mechanism 14 is used to monitor whether the weft thread is broken during the weaving process of the textile shuttle;

[0019] The reel clamping mechanism 2 is two groups of clamping components 3 arranged opposite to each other on the left and right sides. The two groups of clamping components 3 are installed on the shuttle body 1. The two ends of the reel 20 are clamped by the clamping components 3. At the same time, when the reel 20 is unwound, the clamping components 3 rotate with the reel 20. An unwinding detection mechanism 15 is installed on the clamping component 3 located on the right side. The unwinding detection mechanism 15 includes an air pressure sensor 16, a bellows air cavity 17, and a push rod 18. A groove body 19 is opened on the inner side surface of the clamping component 3. The bellows air cavity 17 is embedded in the groove body 19. Patches are adhered to the left and right sides of the bellows air cavity 17 by bolt glue. A spring is installed in the bellows air cavity 17. The two ends of the spring are against the inner wall of the bellows air cavity 17. An air pressure sensor 16 (MEAS air pressure sensor 16MS5637) is built into the bellows air cavity 17. 02BA03-50), the air pressure sensor 16 is installed on the left inner wall of the bellows air cavity 17, the right end of the bellows air cavity 17 is against the inner wall of the groove body 19, and a push rod 18 extending to the left is installed on the patch at the left end of the bellows air cavity 17 by welding. The push rod 18 is a conical rod; two oppositely arranged through holes 21 are opened on the inner wall of the reel 20 near the right end, and a cylinder 22 is inserted into each through hole 21. A lifting spring 23 is sleeved on the cylinder 22, and the lifting spring 23 is welded on the inner wall of the reel 20. The top of the cylinder is flush with the outer wall of the reel through the lifting spring 23, and the push rod 18 extends between the two cylinders 22. When there is no latitude on the reel 20, the cylinder 22 is pushed outward by the push rod 18, and the bellows air cavity 17 expands at the same time, so that the internal air pressure is reduced, so as to monitor whether the unwinding is completed.

[0020] A wire breakage detection mechanism 14 is installed on the side of the clamping assembly 3, and the wire breakage detection mechanism 14 includes a trigger rod 24, a cam groove 26 and a wave cam 27, wherein the trigger rod 24 passes through the clamping assembly 3 and abuts against the right end surface of the bellows air cavity 17, and the left end of the trigger rod 24 extends out of the clamping assembly 3, and a wave cam 27 is installed on the right end of the trigger rod 24 (the wave cam 27 forms a wave shape after being unfolded, so that the trigger rod can move left and right when rotating), and a cam groove 26 matching the wave cam 27 is fixed on the shuttle body 1 by welding, and the wave cam 27 at the end of the trigger rod 24 The trigger rod 24 is against the cam groove 26, and the trigger rod 24 is a prism. The trigger rod 24 rotates synchronously with the clamping assembly 3; when unwinding, the trigger rod 24 rotates with the clamping assembly 3. Since the right end of the trigger rod 24 is a wave cam 27, the trigger rod 24 moves left and right when rotating, which causes the air pressure in the bellows air cavity 17 to change. The air pressure curve within a period of time is wavy. When the weft breaks, the reel 20 stops, and the trigger rod 24 also stops accordingly. In this way, the air pressure is stable and does not change, indicating that the reel 20 stops rotating, thereby realizing line break detection.

[0021] A ring-shaped Bluetooth module 28 (EW199 Bluetooth module 28) is mounted on the right clamping assembly 3 and the Bluetooth module 28 is electrically connected to the air pressure sensor 16. The information of the air pressure sensor 16 is uploaded to the controller (PLC) of the circular loom for analysis through the Bluetooth module 28, and the circular loom is stopped by the controller (the controller controls the start and stop of the circular loom, which is the prior art, and the controller receives the signal from the textile shuttle through the Bluetooth module 28, which is also the prior art; the prior art is that the old circular loom uses electromagnetic sensors to detect weft completion and weft breakage to stop the circular loom).

[0022] The clamping assembly 3 is divided into a left clamping module 4 and a right clamping module 10, an elastic assembly 5 is installed between the left clamping module 4 and the shuttle body 1, the left clamping module 4 includes a sliding rod 6, a left clamping head 7 and a left baffle 9, wherein the left baffle 9 is installed on the left clamping head 7 by bolt fastening, the left clamping head 7 extends into the reel 20 for positioning and clamping, a sliding rod 6 arranged in a horizontal line is installed on the left end of the left clamping head 7 through a bearing, a linear sleeve 8 sleeved on the sliding rod 6 is installed on the shuttle body 1 by bolt fastening, the sliding rod 6 moves left and right along the linear sleeve 8, an elastic assembly 5 is sleeved on the sliding rod 6 between the linear sleeve 8 and the left clamping head 7, and the elastic assembly 5 That is, the clamping spring (the elasticity of the clamping spring is much greater than the elasticity of the spring in the bellows air cavity 17); the right clamping module 10 includes a rotating column 11, a right clamping head 12 and a right baffle 13. The right baffle 13 is installed on the right clamping head 12 by bolt fastening. The right clamping head 12 extends into the reel 20 for positioning and clamping. A rotating column 11 is installed on the right end of the right clamping head 12 by welding, and the rotating column 11 is installed on the shuttle body 1 through a bearing. The rotating column 11 rotates with the right clamping assembly 3, and the groove body 19 embedded in the bellows air cavity 17 is opened on the right clamping head 12 and the rotating column 11. The weft thread and the reel 20 are clamped by the left baffle 9 and the right baffle 13.
