Example

[0024] See also Figure 1-Figure 4The utility model provides a vacuum suction rolling mechanism for acoustic felt, comprising an acoustic felt machine base 1, a support frame 2 is fixedly connected to the upper surface of the acoustic felt machine base 1, a motor 3 is fixedly connected to the left surface of the support frame 2, a winding roller 4 is fixedly connected to the output shaft of the motor 3, a material taking mechanism 5 is arranged on the right surface of the winding roller 4, the material taking mechanism 5 comprises a motor 2 51, a threaded rod 52 is fixedly connected to the output shaft of the motor 2 51, the threaded rod 52 passes through a moving frame 53 and is threadedly connected to the moving frame 53, and a connecting plate 5 is rotatably connected to the left surface of the moving frame 53 4. The right surface of the connecting plate 54 is fixedly connected with an elastic telescopic rod 55 in a circumferential array shape. The elastic telescopic rod 55 is composed of the telescopic rod through a spring. The spring provides elasticity to the telescopic rod. The left surface of the elastic telescopic rod 55 is fixedly connected with an arc-shaped material-retrieving plate 56. The arc-shaped material-retrieving plate 56 is provided with multiple groups. A slide groove 6 is provided on the outer arc surface of one group of arc-shaped material-retrieving plates 56. The inner surface of the slide groove 6 is slidably connected with a vacuum pump 7. The vacuum pump 7 can be limited by the provided slide groove 6 to ensure that the vacuum pump 7 can slide stably in the slide groove 6. The sound-absorbing felt is fully dusted. The outer arc surface of the arc-shaped material-collecting plate 56 is penetrated by an elastic fixing plate 8 and is slidably connected with the elastic fixing plate 8. The elastic fixing plate 8 is composed of a spring and a fixing plate. The spring provides elasticity to the fixing plate. The elastic fixing plate 8 ensures that one end of the sound-absorbing felt can be fixed to facilitate the winding of the sound-absorbing felt. The movable frame 53 is slidably connected to the rear surface of the sound-absorbing felt machine base 1. The arc-shaped material-collecting plate 56 has the same length as the winding roller 4. The cross-sectional shape of the arc-shaped material-collecting plate 56 is U-shaped. By setting the arc-shaped material-collecting plate 56, it can be ensured that After the sound-absorbing felt is rolled up, the threaded rod 52 is driven to rotate by motor 2 51, so that the movable frame 53 moves to the right, and the arc-shaped material-collecting plate 56 is driven to move to the right by the connecting plate 54, so that the rolled-up sound-absorbing felt is removed from the winding roller 4. At the same time, the arc-shaped material-collecting plate 56 can effectively position the sound-absorbing felt, thereby preventing the problem of the sound-absorbing felt needing to be rolled up a second time. The cross-sectional shape of the elastic telescopic rod 55 is L-shaped, and one end of the elastic telescopic rod 55 is fixedly connected to the connecting plate 54, and the other end of the elastic telescopic rod 55 is fixedly connected to the arc-shaped material-collecting plate 56.

[0025] In this embodiment, by providing motor 2 51, movable frame 53, connecting plate 54, elastic telescopic rod 55 and arc-shaped material taking plate 56, the sound-absorbing felt is fixed after being rolled up to prevent the sound-absorbing felt from bouncing up after being rolled up and causing rolling failure. At the same time, the surface of the sound-absorbing felt is dust-removed by the vacuum exhauster 7 to improve the quality of the sound-absorbing felt. Example

[0026] See also Figure 1-Figure 4On the basis of the first embodiment, the utility model provides a technical solution: preferably, a fixing mechanism 9 is provided on the right surface of the winding roller 4, and the fixing mechanism 9 includes a connecting rod 91, and the connecting rod 91 is fixedly connected to the inner surface of the arc-shaped material-retrieving plate 56. A fixing groove 92 is provided on the right surface of the connecting rod 91, and an elastic positioning rod 93 is fixedly connected to the inner surface of the fixing groove 92. The elastic positioning rod 93 passes through the clamping rod 94 and is slidably connected to the clamping rod 94. The elastic positioning rod 93 is composed of a spring and a positioning rod. Through the mutual cooperation between the spring and the positioning rod, the elastic positioning rod 93 is The clamping rod 94 has elastic force, and the cross-sectional shape of the clamping rod 94 is trapezoidal. By setting the cross-sectional shape of the clamping rod 94 to be trapezoidal, the inclined surface of the clamping rod 94 can be squeezed and will shrink into the fixed groove 92. At the same time, the elastic force of the elastic positioning rod 93 can clamp the clamping rod 94 in the limiting groove 11, thereby limiting the arc-shaped material picking plate 56. The right surface of the winding roller 4 is provided with grooves 10 in a circular array, and the inner surface of the groove 10 is provided with limiting grooves 11 in a linear array. The inner surface of the limiting groove 11 is slidably connected to the clamping rod 94.

[0027] In this embodiment, the adjusted arc-shaped material-collecting plate 56 can be fixed by the provided connecting rod 91, elastic positioning rod 93 and clamping rod 94, so as to adapt to the sound-absorbing felt of different thicknesses, ensure that the arc-shaped material-collecting plate 56 can be adjusted, and ensure the stability of the arc-shaped material-collecting plate 56.

[0028] Working principle: when the sound-absorbing felt needs to be rolled up, one end of the sound-absorbing felt is wound around the winding roller 4, and the elastic fixing plate 8 is used to make the elastic fixing plate 8 contact with the sound-absorbing felt through its own elasticity to fix the sound-absorbing felt. The motor 1 3 drives the winding roller 4 to rotate. After the sound-absorbing felt is rolled up, the motor 2 51 drives the threaded rod 52 to rotate, so that the connecting plate 54 drives the elastic telescopic rod 55 and the arc-shaped material-collecting plate 56 to move to the right. After the arc-shaped material-collecting plate 56 takes the sound-absorbing felt out of the winding roller 4, the elastic telescopic rod 55 is used to drive the arc-shaped material-collecting plate 56 to contact with the rolled-up sound-absorbing felt through its own elasticity. At the same time, the inclined surface of the clamping rod 94 will shrink into the groove 10 after being squeezed by the restricted groove 11, and at the same time compress the spring of the elastic positioning rod 93, and the arc-shaped material-collecting plate 56 will clamp the sound-absorbing felt to prevent the sound-absorbing felt from being rolled up again.
