AI Technical Summary
During the working process of the roving machine, due to the relative sliding of the spindle wings and the spindle, the twisting of the sliver is uneven, which affects the quality of the cotton thread. The broken head of the sliver is likely to float into the adjacent sliver, causing the yarn to be disorganized.
A structure including spindles, ingots, baffles, clamp slots, clamp strips, connecting sleeves, clamp sleeves and stops is designed. Through the insertion of clamp strips and clamp slots and the restriction of bumps, the ingots wings are prevented from sliding up and down. And reduce manual operation through the lifting mechanism to ensure that the tampon is broken into the slide chute.
It effectively prevents the ingot from sliding under external force, ensures that the trouser twists evenly, reduces manual operation time, and prevents the trouser from falling off the head, improving the neatness and quality of the cotton thread.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of textiles, in particular to a roving machine for processing cotton threads. Background Art
[0002] Roving frame is a spinning machine that turns fiber strips into roving. According to the twisting mechanism, it can be divided into wing-spindle roving frame and twisting roving frame.
[0003] The cotton balls are broken up into cotton wool by machines, and then the cotton wool is combined into cotton strips. The cotton strips are then rubbed together by roving machines to form roving, making it stronger.
[0004] When the roving frame is working, the cotton sliver is passed through the threading hole of the spindle wing, and then the cotton sliver is wound on the bobbin on the spindle. The spindle drives the spindle wing to rotate, twisting the cotton sliver into roving, and winding the roving onto the bobbin at the same time. When replacing the bobbin of the roving frame, the spindle wing needs to be removed from the spindle. The spindle wing and the spindle are clamped together, and the spindle wing can slide relative to the spindle. When the roving frame is working, the vibration of the machine and the rotation of the spindle will cause the spindle wing and the spindle to slide up and down relative to each other, thereby affecting the twisting of the cotton sliver.

The spindle drives the spindle wing to rotate through the clamping strip and the clamping slot, and the spindle drives the spindle wing to rotate, the cotton strip is twisted into cotton thread, and the protrusion Restricted by the blocks, the spindle wing will not slide up and down on the spindle due to external force, thus affecting the twisting of the cotton sliver. When removing the spindle wing, rotate the sleeve so that the protrusion is located below the gap between the blocks, and then lift the spindle wing upward to separate the spindle wing from the spindle. When the cotton sliver between the spindle and the yarn inlet breaks, the spindle continues to drive the spindle wing to rotate, lift the baffle, and let the broken end fall into the chute of the baffle. Restricted by the chute, the broken end of the cotton sliver will not float into the cotton sliver on the adjacent spindle, thus producing floating cotton.
[0009] Preferably, it also includes a lifting mechanism, which includes a driving mechanism, a scissors frame, and a mounting plate. The driving mechanism is a screw, and the screw is horizontally rotatably connected to the roving machine housing. The two feet at one end of the scissors frame are respectively hinged to the screw slider and the roving machine housing. The surface of the mounting plate is slidably connected with a slider, and the two feet at the other end of the scissors frame are respectively hinged to the mounting plate and the slider on the mounting plate, and the baffle is fixedly connected to the mounting plate.
[0010] By adopting the above technical solution, the lead screw rotates, and its slider drives one foot of the scissors frame to move, so that the scissors frame extends and drives the baffle to rise, replacing manual pulling of the baffle to rise, thereby reducing the time used.
[0011] Preferably, the slot is formed by a vertical slot and a circular slot, and the vertical slot extends to the edge of the baffle.
[0012] By adopting the above technical solution, the broken ends of the cotton sliver fall from the vertical groove into the circular groove, which better prevents the broken ends of the cotton sliver from floating out of the slot.
[0013] Preferably, the outer wall of the ferrule is fixedly connected with friction patterns.
[0014] The adoption of the technical solution makes it easy to rotate the ferrule. BRIEF DESCRIPTION OF THE DRAWINGS
