Description

Technical Field

[0001] The present application relates to the technical field of roving frames, and in particular to a pressure support structure for roving frames. Background Art

[0002] The roving frame (also called flyer roving frame) processes the sliver into roving which is wound on so-called roving bobbins, which can be further processed into yarn on the ring spinning frame. In the roving frame, the sliver first passes through a drafting device, after which the roving is laid onto the roving bobbin by means of a so-called flyer which rotates around the roving bobbin. The roving is thereby simultaneously given the required twist. In order to distribute the roving on the bobbin in the longitudinal direction, the bobbin can be moved in the direction of the axis of rotation of the flyer. To guide the roving, a hold-down is mounted on the flyer.

[0003] After checking the announcement number: CN218372659U, a palm pressing device for a roving machine is disclosed. This technology discloses "including: a yarn feeding tube, a palm pressing rod, a palm pressing arm, a palm pressing plate and a yarn passing tube, the yarn feeding tube is welded to the top of the palm pressing rod, the palm pressing arm is welded to the bottom of the palm pressing rod, the palm pressing plate is installed at the end of the palm pressing arm, the yarn passing tube is spirally fixed on the palm pressing arm and is located on one side of the palm pressing rod, the yarn feeding tube and the center of the yarn passing tube coincide with each other, and the yarn passing tube and the first guide surface and the second guide surface arranged on the palm pressing plate greatly reduce the hairiness generated by the friction between the roving and the palm pressing device, and other technical effects";

[0004] With respect to the above-mentioned related technologies, the inventors believe that the position of the pressure support rod in the pressure support structure of the existing roving machine is generally adjusted manually. Since the position of the pressure support leaf connected to the pressure support rod directly affects the tension of the yarn, it does not have an automatic adjustment mechanism, which makes it inconvenient to automatically adjust the position of the pressure support leaf, thereby reducing the use effect of the pressure support structure; secondly, the pressure support leaf in the existing pressure support structure is not provided with a structure to prevent the yarn from falling off. In the process of the pressure support structure pressing the yarn, the yarn is prone to fall off the pressure support leaf, and the yarn falling off affects the use of the roving machine. Utility Model Content

[0005] The purpose of the present application is to provide a pressure support structure for a roving machine, so as to improve the problem that it is inconvenient to automatically adjust the position of the pressure support blade and the yarn is easily dropped from the pressure support blade during the process of the pressure support structure pressing the yarn.

[0006] The present application provides a roving frame pressure support structure adopting the following technical solution:

[0008] By adopting the above technical scheme and setting up the anti-slip assembly, it is convenient to prevent the yarn from detaching from the pressure-supporting blades during pressure support. When the tension of the yarn needs to be adjusted, the first motor is started, and the output end of the first motor drives the worm transmission, the worm transmission drives the worm wheel to rotate, the rotation of the worm wheel drives the vertical rod to rotate, and the rotation of the vertical rod drives the pressure-supporting rod to rotate a certain angle around the center of the vertical rod, so that the pressure-supporting blades connected to the pressure-supporting rod are adjusted to a suitable use position, thereby improving the pressure-supporting effect of the pressure-supporting structure on the yarn.

[0009] Optionally, the anti-slip assembly includes a bracket, the top of the bracket is fixedly connected to the bottom end of the pressure support leaf, the lower inner wall of the bracket is fixedly connected to the second motor, and the output end of the second motor is fixedly connected to a gear, the outer surface of the gear is meshingly connected to a gear ring, and the inner wall of the gear ring is fixedly connected to a positioning rod, the top of the positioning rod is fixedly connected to a screw, and the outer surface of the screw is threadedly sleeved with a movable plate, one end of the movable plate is fixedly connected to connecting blocks on both sides, and one end of the two connecting blocks is commonly fixedly connected to an anti-slip plate, the bottom end of the pressure support leaf is provided with a guide groove for cooperating with the anti-slip plate, and the top of the anti-slip plate slides through the guide groove.

[0010] By adopting the above technical solution, the second motor is started, and the output end of the second motor drives the gear to rotate, the rotation of the gear drives the gear ring to rotate, the rotation of the gear ring drives the positioning rod to rotate, the rotation of the positioning rod drives the screw to rotate, and the rotation of the screw drives the movable plate to move up and down in the bracket. The movement of the movable plate drives the anti-slip plate to move through the two connecting blocks, and the anti-slip plate passes through the guide groove when moving upward so that the anti-slip plate blocks the notch of the pressure support leaf, thereby avoiding the yarn falling off during pressure support.

[0011] Optionally, the two balance arm rods are both in an inverted "L" shape.

[0012] By adopting the above technical solution, it is convenient to use the two balancing arms together, so that the compression support structure is more balanced when in use.

[0013] Optionally, a limiting ring is fixedly sleeved on the outer surface of the vertical rod, a limiting groove for cooperating with the limiting ring is opened inside one of the balancing arm rods, and the outer surface of the limiting ring is rotatably connected to the inner wall of the limiting groove.

[0014] By adopting the above technical solution, the limiting groove is used in conjunction with the limiting ring to facilitate the positioning of the vertical rod without affecting the rotation of the vertical rod.

[0015] Optionally, the pressure support rod is arc-shaped.

[0016] By adopting the above technical solution, the arc shape facilitates the compression rod to play a better connection role, making it more convenient to compress the yarn.
