Description

Technical Field

[0001] This utility model relates to the field of flat-bottomed spindle technology, specifically a high-speed flat-bottomed spindle with longitudinal buffer. Background Technology

[0002] In recent years, the textile industry has developed rapidly, demanding high speed, high efficiency, high quality, and a wide variety of products. The current spindle speed range in the market is 8,000 to 18,000 rpm.

[0003] Application number CN200720091025.2 discloses a spinning spindle with longitudinal cushioning at the bottom of a flat spindle. It includes a spindle rod, bearing gaskets, a spindle bearing, an upper bearing seat, a spindle foot, an elastic tube, a positioning sleeve, a coil spring, a copper sleeve, and a flat spindle bottom. This spinning spindle features longitudinal cushioning, reducing longitudinal impact during doffing on the spinning frame and adapting to automated doffing. It can reduce the longitudinal force and impact on the spindle during high-speed operation, improving the spindle's stability and extending its service life. However, in practical use, this application results in the intermittent generation of slag. Because this slag cannot be discharged or collected, it causes gradual wear on the outer structure of the spindle rod, severely reducing the product's service life. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A high-speed flat-bottomed ingot with longitudinal buffer includes a power mechanism and a slag discharge mechanism. The power mechanism includes a support tube, a central shaft connected to the bottom of the inner cavity of the support tube, an ingot bottom connected to the top of the central shaft, and an ingot rod attached to the top of the ingot bottom. The slag discharge mechanism includes multiple leakage holes opened on the ingot bottom, an outer magnetic ring embedded in the inner wall of the support tube, an inner magnetic ring sleeved on the outside of the central shaft, and a slag zone formed between the outer magnetic ring and the inner magnetic ring.

[0007] By adopting the above technical solution, the slag generated by the rotation of the spindle enters the slag zone through multiple holes. Then, the outer and inner magnetic rings work together to completely adsorb the slag. This magnetic attraction method effectively prevents the slag from shaking and protects the service life of the internal structure of the support tube.

[0008] In a preferred embodiment, the present invention can be further configured such that the central shaft, the ingot bottom, and the ingot rod are vertically coaxial, and the top of the ingot bottom has an arc surface.

[0009] In a preferred embodiment, the present invention can be further configured as follows: multiple leak holes are equally spaced and arranged in a ring, and the leak holes are connected to the interior of the slag area.

[0010] In a preferred embodiment, the present invention can be further configured such that the height of the outer magnetic ring is equal to the height of the inner magnetic ring, and the height of the outer magnetic ring is less than the height of the central axis.

[0011] In a preferred embodiment, the present invention can be further configured such that: a sliding bearing is provided at the top of the ingot bottom, and the sliding bearing is connected between the support tube and the ingot rod.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of rollers are movably embedded inside the support tube, and the outer wall of the spindle bottom is in contact with the outer wall of the rollers.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the slag generated by the rotation of the spindle enters the slag area through multiple holes, and then the outer magnetic ring and inner magnetic ring cooperate to completely adsorb the slag. This magnetic attraction method effectively prevents the slag from shaking and protects the service life of the internal structure of the support tube.

[0015] 2. In this utility model, the spindle rod rotates smoothly under the support of the spindle bottom and the limiting position of the sliding bearing. Then, the sliding bearing bears the longitudinal load, further ensuring the rotational stability of the spindle rod. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-speed flat-bottomed spindle with longitudinal buffer.

[0028] Example 1:

[0029] Combination Figure 1-4 As shown, the present invention provides a high-speed flat-bottomed spindle with longitudinal buffer, including a power mechanism 100 and a slag discharge mechanism 200. The power mechanism 100 includes a support tube 110, a central shaft 120 connected to the bottom of the inner cavity of the support tube 110, a spindle bottom 130 connected to the top of the central shaft 120, and a spindle rod 140 that fits against the top of the spindle bottom 130.

[0030] The slag discharge mechanism 200 includes a plurality of drain holes 210 opened on the ingot bottom 130, an outer magnetic ring 220 embedded in the inner wall of the support tube 110, an inner magnetic ring 230 sleeved on the outside of the central shaft 120, and a slag zone 240 formed between the outer magnetic ring 220 and the inner magnetic ring 230.

[0031] Furthermore, the central shaft 120, the ingot bottom 130, and the ingot rod 140 are vertically coaxial, and the top of the ingot bottom 130 is provided with an arc surface, which can guide the stability of the rotation of the ingot rod 140.

[0032] Furthermore, multiple perforations 210 are evenly spaced and arranged in a ring. The perforations 210 are connected to the interior of the slag zone 240. The layout design of the perforations 210 can quickly screen out the slag produced by the ingot rod 140 and avoid the slag from wearing down the ingot rod 140 and the ingot bottom 130.

[0033] Furthermore, the height of the outer magnetic ring 220 is equal to the height of the inner magnetic ring 230, and the height of the outer magnetic ring 220 is less than the height of the central shaft 120. The size design of the outer magnetic ring 220 and the inner magnetic ring 230 ensures that the slag adsorbed by them is at a certain distance from the top of the ingot bottom 130, preventing the slag from being sucked away by the rotating ingot rod 140.

[0034] Example 2:

[0035] Combination Figure 1-2As shown, based on Embodiment 1, a sliding bearing 300 is provided at the top of the spindle bottom 130. The sliding bearing 300 is connected between the support tube 110 and the spindle rod 140. The sliding bearing 300 is provided to bear the longitudinal load and ensure the rotational stability of the spindle rod 140.

[0036] Example 3:

[0037] Combination Figure 2 As shown, in the above embodiment, a plurality of rollers 400 are movably embedded inside the support tube 110, and the outer wall of the spindle bottom 130 is in contact with the outer wall of the rollers 400. The rollers 400 can limit the spindle bottom 130 and improve the installation firmness of the spindle bottom 130.

[0038] The working principle and usage process of this utility model: When this device is put into actual use, the spindle rod 140 rotates stably under the support of the spindle bottom 130 and the limiting position of the sliding bearing 300. During the rotation, the generated slag enters the slag area 240 through multiple leakage holes 210. Then, the outer magnetic ring 220 and the inner magnetic ring 230 cooperate to completely attract the slag. This magnetic attraction method effectively prevents the slag from shaking and protects the service life of the internal structure of the support tube 110.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
