Description

Technical Field

[0001] This utility model relates to the field of spinning technology, specifically to a smooth spindle for a collective doffing device. Background Technology

[0002] The original collective doffing modification required replacing the spindles, replacing the original smooth spindles with aluminum sleeve spindles. This necessitated adjusting the cross-sectional height of the spinning machine to match the aluminum sleeve spindles. The modification cost was high, and the original smooth spindles were directly discarded, resulting in significant waste. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a smooth spindle for a collective doffing device, which can effectively solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a spindle rod and a spindle tray; the spindle tray is mounted on the spindle rod; it further comprises:

[0005] A support, which is sleeved on the spindle rod and located at the upper end of the spindle disc;

[0006] A yarn winder is fitted onto the outer protrusion of the spindle disc, and a cutting blade is installed on the outer edge of the upper port of the yarn winder.

[0007] Preferably, the cutting blades are a plurality of blades, which are installed at equal angles in the grooves on the outer edge of the upper port of the yarn winder.

[0008] Preferably, a gap is provided between the lower part of one side of the inner wall of the support and the outer wall of the spindle, and a support protrusion is integrally formed at the bottom of the outer wall of the support at the gap position.

[0009] Preferably, the contact surface between the yarn winder and the boss on the outside of the spindle disc is a sloping surface structure.

[0010] Preferably, the outer edge of the upper port of the support is provided with a sloping, tapering structure, which is configured to cooperate with the sloping surface of the inner wall of the yarn tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a smooth spindle for a collective doffing device. By adding a yarn winder (including a cutting blade) and a support to the spindle disc and spindle rod, the original contact-type cooperation method is changed to an elastic cooperation method with the support inside, thereby realizing the easy tube removal function of the yarn tube and satisfying the feasibility of collective doffing and collective tube removal.

[0015] Support 1, gap 1-1, support protrusion 1-2, cutter blade 2, yarn winder 3, spindle disc 4, spindle rod 5. Detailed Implementation

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-2 As shown, this specific embodiment adopts the following technical solution: it includes a spindle rod 5 and a spindle tray 4; the spindle tray 4 is mounted on the spindle rod 5; it also includes:

[0018] Support 1 is sleeved on spindle rod 5 and located at the upper end of spindle disc 4; a gap 1-1 is provided between the lower part of one side of the inner wall of support 1 and the outer wall of spindle rod 5, and a support protrusion 1-2 is integrally formed at the bottom of the outer wall of support 1 at the position of gap 1-1; the outer edge of the upper port of support 1 is set in a sloping and converging structure, which is matched with the sloping surface of the inner wall of yarn tube.

[0019] The yarn winder 3 is sleeved on the outer boss of the spindle disc 4. The contact surface between the yarn winder 3 and the outer boss of the spindle disc 4 is a sloping surface structure. Several cutting blades 2 are installed at equal angles on the groove on the outer edge of the upper port of the yarn winder 3.

[0020] When using this utility model, the yarn tube is sleeved on the spindle 5, so that the lower end of the yarn tube is installed in the upper end of the yarn winder 3; the inner wall of the yarn tube is squeezed against the support protrusions 1-2 on the support 1, and the support protrusions 1-2 react on the inner wall of the yarn tube, thereby providing elastic support for the yarn tube, realizing the easy-to-pull-out function of the yarn tube, and satisfying the feasibility of collective yarn doffing and collective tube pulling.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Can be installed directly on site; the original spindle requires no processing or damage.

[0023] 2. The modification is simple and does not require changing the cross-sectional height of the spinning machine;

[0024] 3. Cost-saving, no need to replace spindles or yarn bobbins, direct connection between upstream and downstream processes;

[0025] 4. Increase production and save labor. The special blades produce neat and flat cuts, increasing the efficiency of the winding process.

[0026] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
