[0020] The specific embodiments of the utility model will be described in detail below with reference to the drawings.
[0021] As Figures 1-5 shown, the utility model is a telescopic waste yarn suction pipe mechanism.
[0022] The telescopic waste yarn suction pipe mechanism comprises a mounting panel 3, the mounting panel 3 is provided with a through negative pressure suction port 2, the negative pressure suction port 2 is a circular hole structure, is opened or covered by a moving air door 4, and the waste yarn is sucked by the waste yarn suction pipe mechanism 1 when the negative pressure suction port 2 is opened. Figure 3As shown, a cylindrical section of the upper waste yarn suction pipe 16 extends into the upper waste yarn suction pipe 11, and the lower waste yarn suction pipe 16 is lowered to suck the waste yarn. The lower waste yarn suction pipe 16 is driven to be lowered by the driving mechanism arranged on the upper waste yarn suction pipe 11, and is automatically returned to be raised by the return mechanism after the suction is completed.
[0023] Further, the driving mechanism is a plurality of air cylinders 12 arranged on the upper waste yarn suction pipe 11, which extend to push the lower waste yarn suction pipe 16 to be lowered and be pressed on the mounting panel 3 to be connected with the negative pressure suction pipe 2.
[0024] Further, the return mechanism is a plurality of springs 13 arranged on the upper waste yarn suction pipe 11 and the lower waste yarn suction pipe 16. The upper side of the spring 13 is provided with an open check ring 17 and a check piece 18 to fix the spring 13 and the pull rod 14. The pull rod 14 passes through the second flange plate 161 and the first flange plate 111, and the spring 13 is arranged on the upper side of the first flange plate 111. When the lower waste yarn suction pipe 16 is lowered, the pull rod 14 is also lowered to press the spring 13, and the spring 13 returns to raise the lower waste yarn suction pipe 16.
[0025] Further, the upper waste yarn suction pipe 11 is provided with the first flange plate 111, and the lower waste yarn suction pipe 16 is provided with the second flange plate 161, which are used for fixing the air cylinder 12 and the pull rod 14. The first flange plate 111 is an integral structure with the upper waste yarn suction pipe 11, and the second flange plate 161 is an integral structure with the lower waste yarn suction pipe 16. The first flange plate 111 is arranged at the lower end of the upper waste yarn suction pipe 11, and the second flange plate 161 is arranged at the middle of the lower waste yarn suction pipe 16.
[0026] Further, the waste yarn suction pipe mechanism 1 further includes a limiting screw 15 for positioning. The limiting screw 15 is threadedly connected to the second flange plate 161 and is fastened by a nut. When the lower waste yarn suction pipe 16 is lowered, the tail end of the limiting screw 15 abuts against the first flange plate 111 to position the lower waste yarn suction pipe 16.
[0027] Further, the number of the air cylinder 12 and the pull rod 14 is 3. The air cylinder 12 is arranged on the first flange plate 111 and extends to push the second flange plate 161 to move the lower waste yarn suction pipe 16 downward as a whole.
[0028] When the telescopic waste yarn suction pipe mechanism is used, the cylinder starts to act, pushes the waste yarn suction pipe down to move down, and is pressed on the installation panel to be connected with the negative pressure suction pipe, so that the size of the suction nozzle forms negative pressure, and waste yarn can also be smoothly sucked by the negative pressure suction pipe. When the trolley completes the splicing operation, the cylinder stops supplying air. Since the waste yarn suction pipe is pressed down to compress the spring, when the cylinder loses the pushing force, the spring pulls the waste yarn suction pipe up through the pull rod to move up to the original position. The distance between the waste yarn suction pipe and the installation panel can be adjusted by the limiting screw, which needs to ensure that there is no knot, and the installation panel is not in contact, and the rotating air door can be pushed to rotate.
[0029] The above is the preferred embodiment of the present application, which does not limit the protection scope of the present application. Any deformation and improvement made by those skilled in the art according to the design idea of the present application should be considered within the protection scope of the present application.
