[0034] like Figure 1-8 As shown, a sliver missing warning device for a rotor textile machine includes a sliver can 100 and a warning mechanism 200. The warning mechanism 200 is provided with the sliver can 100. Side plates 110 are installed below both sides of the circumferential outer wall of the sliver can 100. A T-shaped connecting block 120 is installed on one side of the lower surface of the side plate 110, and a triangular groove 111 is opened on the lower surface of the side plate 110.

[0035] The warning mechanism 200 is provided with a first U-shaped plate 210, and limiting columns 214 are installed at the four corners of the lower surface of the first U-shaped plate 210. The bottom end of the limiting column 214 passes through the through hole on the surface of the second U-shaped plate 240 and is connected to the limiting plate 290. The outer side of the outer wall of the limiting column 214 is provided with a spring 280, and the spring 280 is located between the first U-shaped plate 210 and the second U-shaped plate 240. Telescopic components 250 are installed on both sides of the upper surface of the second U-shaped plate 240, and a mounting plate 260 is installed on the top of the telescopic component 250, and the lower surface of the mounting plate 260 A touch switch 270 and a telescopic component 250 are installed. The horizontal height of the touch switch 270 can be adjusted during the telescopic operation of the telescopic component 250. The staff can control the amount of slivers remaining in the sliver barrel 100 by adjusting the horizontal height of the touch switch 270 and issue an early warning. Bumps 211 are installed on both sides of the front end wall of the first U-shaped plate 210, and rollers 212 are provided on the upper surface of the bumps 211. A battery box 230 is installed on the rear end of the upper surface of the first U-shaped plate 210, and an audible and visual alarm 220 is installed on the top of the battery box 230.

[0036] There is a clearance fit between the outer wall of the limiting column 214 and the wall of the through hole on the second U-shaped plate 240.

A threaded hole is provided at the center position of the surface of the limiting plate 290, and the external thread on the outer wall of the limiting column 214 and the threaded hole on the limiting plate 290 are threadedly connected. Since there is a clearance fit between the outer wall of the limiting column 214 and the wall of the through hole on the second U-shaped plate 240, it can play a role in limiting and guiding the movement of the first U-shaped plate 210. Since there is a threaded fit between the external thread on the outer wall of the limiting column 214 and the threaded hole on the limiting plate 290, the staff can disassemble and replace the spring 280.

[0037] The T-shaped connecting block 120 is installed in the T-shaped connecting groove 213 . There is a clearance fit between the outer wall of the T-shaped connecting block 120 and the groove wall of the T-shaped connecting groove 213 . The T-shaped connecting groove 213 is provided on both sides of the upper surface of the first U-shaped plate 210 .

[0038] A self-locking universal wheel 130 is installed at the bottom end of the sliver can 100. There are four self-locking universal wheels 130, and the four self-locking universal wheels 130 are distributed in a ring array. The setting of the self-locking universal wheel 130 makes it convenient for the staff to move or fix the sliver can 100. A battery is set inside the battery box 230, and the battery can provide electricity for the utility model.

[0039] A support plate 241 is mounted on the lower surface of the second U-shaped plate 240 .

[0040] The telescopic assembly 250 is provided with a mounting post 252, and a mounting groove 2521 is provided at the center of the top end of the mounting post 252. The telescopic post 251 is installed in the mounting groove 2521, and the outer wall of the telescopic post 251 and the groove wall of the mounting groove 2521 are clearance-fitted. A threaded hole is provided at the center of the bottom end of the telescopic post 251, and a first rotating shaft 253 is installed in the threaded hole. The outer wall of the first rotating shaft 253 is provided with an external thread, and the external thread on the outer wall of the first rotating shaft 253 is threadedly connected to the threaded hole on the telescopic post 251.

[0041] The bottom end of the first rotating shaft 253 passes through the bearing on the surface of the connecting plate 2523 and is connected to the first bevel gear 2531, and the connecting plate 2523 is arranged at the bottom inside the mounting groove 2521, the first bevel gear 2531 is meshed with the second bevel gear 2542, the second bevel gear 2542 is installed at one end of the second rotating shaft 254, and the other end of the second rotating shaft 254 passes through the bearing on the outer wall of the mounting column 252 and extends to the outside to be connected with the rotation adjustment plate 2541, and a limit block 2511 is provided on both sides of the circumferential outer wall of the telescopic column 251, and the other end of the limit block 2511 is installed in the limit groove 2522, and there is a gap between the outer wall of the limit block 2511 and the groove wall of the limit groove 2522. It is a clearance fit, and the limit groove 2522 is opened on the circumferential inner wall of the installation groove 2521. Since there is a clearance fit between the outer wall of the telescopic column 251 and the groove wall of the installation groove 2521, there is a clearance fit between the outer wall of the limit block 2511 and the groove wall of the limit groove 2522, thereby playing a role of limiting and guiding the movement of the telescopic column 251. When the staff rotates the rotary adjustment plate 2541 forward or reverse, it will indirectly drive the first rotating shaft 253 to rotate forward or reverse. Since the external thread on the outer wall of the first rotating shaft 253 and the threaded hole on the telescopic column 251 are threadedly connected, the first rotating shaft 253 will play a role of limiting and guiding the movement of the telescopic column 251 when it rotates forward or reverse.

[0042] Working principle: When in use, when the sliver can 100 is located on the warning mechanism 200 and is conveying slivers to the rotary textile machine, as the slivers in the sliver can 100 continue to decrease, the pressure caused by the sliver can 100 on the first U-shaped plate 210 will continue to decrease. Under the rebound force of the spring 280, the sliver can 100 will move upward in the Y-axis direction. When the sliver can 100 moves upward in the Y-axis direction to a certain horizontal height, the surface of the side plate 110 on the sliver can 100 contacts the touch switch 270, the sound and light alarm 220 opens and sounds a sound and light alarm. Therefore, the utility model can play the role of automatic warning when the slivers in the sliver can 100 are less, reminding the staff to replace the sliver can 100 in time, avoiding the situation where the slivers in the sliver can 100 are missing and the continuity of the production of the rotary textile machine is reduced. When the staff needs to install the tampon can 100 on the early warning mechanism 200, the staff pushes the tampon can 100 and makes the top of the inner wall of the triangular groove 111 contact with the top of the roller 212. The inner wall of the triangular groove 111 will cause a certain downward force on the roller 212. When the staff continues to push the tampon can 100, the roller 212 moves relatively in the triangular groove 111. When the roller 212 moves out of the triangular groove 111 and contacts the lower surface of the side plate 110, the first U-shaped plate 210 will move downward to a certain horizontal height under the above-mentioned force. When the staff continues to push the tampon can 100, the T-shaped connecting block 120 will move into the T-shaped connecting groove 213. When the T-shaped connecting block 120 is completely moved into the T-shaped connecting groove 213, the installation of the tampon can 100 on the early warning mechanism 200 is completed.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
