Technical Field
[0001] This utility model relates to a flax roving spindle, and more particularly to a novel flax roving spindle, belonging to the field of textile equipment technology. Background Technology
[0002] Currently, the roving tube suspension section on spinning frames generally uses a two- or three-support structure. Publication number CN 207468795 U discloses a novel spinning spindle structure with two supports. This structure offers flexible rotation, but the two-claw support structure lacks self-adjusting center of gravity, resulting in significant tension fluctuations during roving unwinding. Publication number CN2120310U discloses a novel three-claw spinning spindle with three supports. However, this three-support structure is asymmetrical, still exhibiting significant tension fluctuations during roving unwinding, which negatively impacts the accuracy of the roving tube's mounting position. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing linen roving bobbins, such as large tension fluctuations during roving unwinding and incorrect bobbin placement, by providing a new type of linen roving bobbin that achieves smaller tension fluctuations and more accurate bobbin placement during roving unwinding.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a novel flax roving spindle, comprising a connecting screw, a spindle cap, and a spindle base; the connecting screw is used to connect the spindle to external machinery, the spindle cap is disposed on the spindle base, the central through hole of the spindle cap is sleeved on the connecting screw, and the spindle base is fixedly connected to the lower end of the mounting bolt.
[0005] It also includes a sliding sleeve, a support ring, a return spring, a mandrel, a push spring, a positioner, a tension spring, a support plate assembly, and a pin; the upper end of the sliding sleeve is inserted into the lower part of the lifting base; the support ring is sleeved on the lower part of the sliding sleeve; the support plate assembly is located in the lower part of the sliding sleeve; the positioner is located on the push spring, and the rotation shaft of the positioner is located in the middle of the mandrel; the pin is located at the bottom of the sliding sleeve;
[0006] The mandrel and the push spring are assembled together and disposed in the middle of the sliding sleeve; the return spring is disposed inside the sliding sleeve and sleeved on the outside of the mandrel; the return spring serves to reset the mandrel.
[0007] The mandrel has two downward steps A on its outer side and two support protrusions on its inner side; the side wall of the sliding sleeve has a strip-shaped guide groove and the support protrusions are located in the guide groove; when the support ring is pushed upward, the support protrusions will push against the steps A.
[0008] The support plate group includes four support plates, each support plate having an upper connecting part, a middle tightening part, and a lower supporting part; the tightening spring is disposed around the tightening part and tightly tightens the four support plates; the pin is vertically aligned with the middle of the four supporting parts;
[0009] The lower part of the sliding sleeve has four support plate telescopic slots evenly distributed. The support parts of the four support plates are respectively set in the four support plate telescopic slots and extend outward. The four support plates are completely symmetrically arranged around the center line and have the function of self-adjusting the center of gravity to ensure that the lifting position of the spindle is correct. The indexer is located in the middle of the push spring, and the indexer's rotating shaft is set in the middle of the spindle.
[0010] The lower end of the mandrel is provided with an annular groove, and the clamping spring evenly clamps the four clamping parts in the annular groove.
[0011] The lower part of the connecting screw is provided with a ball cup, and the inner side wall of the hanging cap and the upper end of the ball cup are fixedly provided with a bearing, which includes balls and a cage.
[0012] When the support ring is pushed upward, the spindle and push spring slide upward first, the indexer rotates, and the support plates move upward and retract. The indexer locks, and when the support plates are retracted, the four support parts are located on the top of the pins; the spindle can easily enter and exit the yarn bobbin. When the support ring is pushed upward again, the spindle and push spring slide upward first, then the indexer rotates and unlocks. The reset spring pushes the spindle and push spring downward, simultaneously pushing the four support plates. When the four support plates are pushed downward, because there are pins under the four support parts, the four support plates are spread open by the pins, so that the four support plates are in an open state, and the support plates can stably suspend the yarn bobbin, completing the entire hoisting process.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the four support plates are symmetrically arranged, which has the function of self-adjusting the center of gravity, so that the spindle is correctly hoisted; and a combination structure of sliding sleeve, push spring, mandrel, support ring and pin is designed to adapt to the opening and closing of the four support plates, so as to provide a flax roving spindle with smooth rotation, small and uniform unwinding tension of yarn bobbin, reliable rotation action and correct hoisting position of the bobbin.
