Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically a cotton spindle with a double elastic damping component. Background Technology

[0002] The cotton spindle is the core high-speed rotating component of spinning equipment such as ring spinning machines and twisting machines. Its main functions are: to clamp the yarn and rotate it at high speed; the cotton spindle twists the yarn by rotating (making the fibers cohesive and forming strength), and at the same time winds the twisted yarn onto the yarn bobbin to form a bobbin yarn.

[0003] Existing cotton spindles, such as the low-noise cotton spindle disclosed in publication number CN210684044U, have solved the problem of noise generated during high-speed rotation of cotton spindles and can ensure smooth rotation of cotton spindles to achieve the effect of vibration reduction. However, the vibration reduction structure of this cotton spindle is set on the upper side, which makes it inconvenient to form a two-way vibration reduction structure, resulting in poor vibration reduction effect. Therefore, we propose a cotton spindle with a double elastic vibration reduction component. 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 cotton spinning spindle with a dual-elastic vibration damping component includes: a spindle body and a vibration damping structure; the spindle body includes a spindle rod, a left spindle plate and a right spindle plate respectively movably mounted on both sides of the spindle rod; the vibration damping structure includes a bearing fixedly mounted on the outer end of the spindle rod, a fixed sleeve fixedly mounted on the outer end of the bearing, a vibration damping pad fixedly mounted on the outer sides of both the upper and lower ends of the fixed sleeve, a vibration damping spring fixedly mounted on the inner sides of both the upper and lower ends of the fixed sleeve, and a fixed plate fixedly mounted on one end of each vibration damping spring.

[0007] Preferably, both the left and right spindles are provided with shock-absorbing cavities in the middle, and the fixing sleeve and shock-absorbing pad are movably matched and installed in the shock-absorbing cavities.

[0008] Preferably, the upper and lower parts of the left and right spindles are each provided with a binding cavity, and the fixed discs are movably matched and installed in the binding cavity.

[0009] Preferably, threaded holes and mounting holes are respectively provided at the four corners of the left and right spindles.

[0010] Preferably, screws are also movably installed in both the threaded hole and the mounting hole.

[0011] Preferably, a spindle foot is fixedly installed at the bottom of the left spindle disk.

[0012] Preferably, the damping springs in both the left and right spindles are in a compressed state.

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

[0014] In this invention, the damping springs in the upper and lower parts of the inner fixing sleeves of the left and right spindle discs are in a compressed state, which can form a bidirectional compression damping structure for the spindle rod in the middle to suppress the vibration of the spindle rod during use. At the same time, after the spindle rod vibrates during use, the damping pads at the upper and lower parts of the fixing sleeve can also deform to absorb the vibration to avoid resonance. Thus, through the damping springs and damping pads at the upper and lower parts of the outer fixing sleeve of the spindle rod, a double elastic damping structure is formed to reduce the vibration of the spindle rod during use and improve its service life.

[0021] 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.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a cotton spindle with a dual elastic damping component.

[0023] Example 1:

[0024] Combination Figure 1-3As shown, this utility model provides a cotton spinning spindle with a double elastic vibration damping component, comprising: a spindle body 100 and a vibration damping structure 200; the spindle body 100 includes a spindle rod 101, a left spindle plate 102 and a right spindle plate 103 respectively movably mounted on both sides of the spindle rod 101, and a spindle foot 104 fixedly mounted at the bottom of the left spindle plate 102; the vibration damping structure 200 includes a bearing 201 fixedly mounted on the outer end of the spindle rod 101, a fixing sleeve 202 fixedly mounted on the outer end of the bearing 201, vibration damping pads 203 fixedly mounted on the outer sides of both the upper and lower ends of the fixing sleeve 202, vibration damping springs 204 fixedly mounted on the inner sides of both the upper and lower ends of the fixing sleeve 202, and one end of each vibration damping spring 204... The fixed plate 205 is fixedly installed. The middle of the left spindle plate 102 and the right spindle plate 103 are also provided with shock-absorbing cavities 206. The fixed sleeve 202 and the shock-absorbing pad 203 are movably matched and installed in the shock-absorbing cavities 206. The upper and lower parts of the left spindle plate 102 and the right spindle plate 103 are also provided with binding cavities 207. The fixed plate 205 is movably matched and installed in the binding cavities 207. The four corners of the left spindle plate 102 and the right spindle plate 103 are respectively provided with threaded holes 208 and mounting holes 209. Screws 210 are movably installed in the threaded holes 208 and the mounting holes 209. The shock-absorbing springs 204 in the left spindle plate 102 and the right spindle plate 103 are in a compressed state.

[0025] Specifically, the cotton spindle is a core high-speed rotating component in spinning equipment such as ring spinning frames and twisting machines. In the spindle body 100, the damping springs 204, with their upper and lower parts compressed within the fixed sleeves 202 of both the left and right spindle discs 102 and 103, form a bidirectional compression damping structure on the central spindle rod 101 to suppress vibrations during use. Simultaneously, after vibrations occur during use, the damping pads 203 located above and below the fixed sleeves 202 can deform and absorb the vibration to prevent resonance. Thus, through the damping springs 204 and damping pads 203 on the outer fixed sleeves 202 of the spindle rod 101, a double-elastic damping structure is formed to reduce vibrations during use of the spindle rod 101. To improve its service life, the bearing 201 at the outer end of the spindle 101 mainly facilitates the rotation of the spindle 101. The damping cavity 206 opened in the middle of the left spindle 102 and the right spindle 103 mainly facilitates the matching installation of the fixing sleeve 202 and the damping pad 203 on the spindle 101. The binding cavity 207 opened at the upper and lower parts of the left spindle 102 and the right spindle 103 mainly facilitates the binding installation of the fixing plate 205 at the outer end of the damping spring 204, so that the damping spring 204 inside the fixing plate 205 is in a compressed state. The screw 210 locked in the threaded hole 208 and the mounting hole 209 between the left spindle 102 and the right spindle 103 is mainly used to ensure the stability between the left spindle 102 and the right spindle 103.

[0026] Working principle and usage process of this utility model:

[0027] When the spindle rod 101 inside the left spindle disk 102 and the right spindle disk 103 vibrates during use, the damping spring 204, which is in a compressed state at the top and bottom of the fixed sleeve 202, will reduce the vibration of the spindle rod 101 by axially pressing the fixed sleeve 202 and the spindle rod 101. At the same time, the damping pad 203 at the top and bottom of the fixed sleeve 202 can also deform to absorb the vibration of the spindle rod 101 during vibration, thus avoiding the vibration of the outer left spindle disk 102 and the right spindle disk 103. In this way, the double-layer vibration damping structure at the top and bottom of the left spindle disk 102 and the right spindle disk 103 reduces the vibration of the spindle rod 101 during use and extends its service life.

[0028] 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.
