Description

Technical Field

[0001] This invention relates to the field of textile accessories technology, and in particular to a spindle for a textile machine. Background Technology

[0002] Spinning machines in textile machinery require the use of spindles. The main function of a spindle used in textile machines is to suspend the roving tube and unwind the roving. Its specific uses can be divided into two categories: one is to change the roving by extending and retracting the support plate; the other is to ensure the normal rotation of the roving during the spinning process by relying on the appropriate and stable traction force of the spindle itself. If the traction force is too large, the roving will be unexpectedly stretched, and if the traction force is too small, the roving will unwind too quickly and fall off.

[0003] The main structure of the existing spindle under the existing technical standard adopts a damping cover and a steel ball cup structure. For the existing spindle, when the roving is unwound from the roving tube, the spindle used in the textile machine is rotated horizontally by the strength of the roving yarn itself to unwind the roving. This method is called passive unwinding. Specifically, the unwinding of different yarn groups is achieved by changing the position of the support piece by moving the pressure ring up and down. The main determining factors for improving work efficiency are the flexibility of the pressure ring and the diversity of the support piece position changes. An existing improved spindle design for textile machines is also mainly designed to address these two influencing factors. The spindle designed in this paper also makes corresponding improvements to these two aspects.

[0004] The existing spindle for textile machines has problems such as insufficient flexibility in the movement of the pressing mechanism, poor practicality of single sheets, and lack of necessary limiting protection mechanism in the middle section of the positioning column. Therefore, we propose a spindle for textile machines. Summary of the Invention

[0005] The main objective of this invention is to provide a spindle for textile machines that can effectively solve problems in the prior art such as insufficient mobility of the pressing mechanism, poor practicality of single sheets, and lack of necessary limiting and protection mechanisms in the middle section of the positioning column.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a spindle for a textile machine, comprising a positioning column, a cylindrical shaft, a pressing mechanism and a yarn hanging mechanism disposed on the cylindrical shaft, and a protective mechanism disposed on the positioning column. The pressing mechanism includes a slide, a pressing ring, and a retainer. The pressing ring has a frustum-shaped structure and is hollow inside. The cylindrical shaft has two slides on its sidewall, which are symmetrical along the central axis. The two slides are movably connected to the two slides on the side closest to the cylindrical shaft, and the other ends of the two slides are connected to the inner sidewall of the pressing ring. Four retainers are symmetrically disposed on the outer sidewall of the pressing ring along the central axis. The yarn hanging mechanism includes a rotating shaft, a first support plate, a second support plate, and a rotating column. The two rotating shafts are respectively disposed inside the two slides and located on the side away from the positioning column. The two first support plates are respectively connected to the two rotating shafts. The shaft is movably connected, and four rotating holes are provided at corresponding positions of the two second support plates. Four rotating columns are respectively provided on the side walls of the two first support plates along the central axis. The other ends of the four rotating columns are movably connected to the four rotating holes. The limiting protection mechanism includes a steel ball cup, a retaining ring, a connecting column, a connecting ring, a connecting rod, and a bushing. The steel ball cup has an internally hollow structure, and the bushing has a cylindrical structure with an internally hollow structure. A first sliding hole is provided at the center of the steel ball cup. The positioning column is movably connected to the first sliding hole. Two connecting columns are symmetrically provided on the inner side walls of the steel ball cup along the central axis. The other ends of the two connecting columns are respectively connected to the side walls of the two retaining rings. Two connecting rings are movably connected to the two connecting columns. Two connecting rods are symmetrically provided above the bushing along the central axis. The other ends of the two connecting rods are respectively connected to the circumferential side surfaces of the two connecting rings.

[0007] Preferably, the positioning post further includes a helical rod, a ratchet, and a support ring. The helical rod is located below the positioning post, and the other end of the helical rod is movably connected to the ratchet. The support ring is located on the side of the ratchet away from the positioning post. The movable connection between the helical rod and the ratchet realizes the locking of the positioning post and the cylindrical shaft, and at the same time facilitates the replacement of different positioning posts.

[0008] Preferably, the cylindrical shaft further includes a conical ring, which is located on the side of the cylindrical shaft away from the positioning post, and the conical ring mainly provides the necessary gravity support for the cylindrical shaft.

[0009] Preferably, the positioning column further includes a dustproof component, which is located outside the limiting protection mechanism and provides necessary dustproof technical support for the internal core part.

[0010] Preferably, the dustproof assembly includes a dust cover, a dust cap, a limiting ring, and a spacer. The dust cover has an internal hollow structure. The dust cap has a second sliding hole at its center. The positioning post is movably connected to the second sliding hole. The limiting ring is located on the upper outer side of the dust cover. The spacer is located between the dust cover and the positioning post, and the spacer is movably connected to the positioning post. The design of the spacer ensures more rigorous internal dustproofing and facilitates the rotation of the positioning post.

[0011] Preferably, the steel ball bowl includes a top frame, and two top frames are symmetrically arranged along the central axis on the inner side wall of the steel ball bowl. The other end of each of the two top frames is connected to the inner side wall of the dust cover. The design of the top frame can increase the connection stability between the dust cover and the steel ball bowl.

[0012] Preferably, the positioning column further includes a connecting component, which is disposed on the side wall of the positioning column. The connecting component is mainly for facilitating the connection and use of a spindle device for textile machines with a spinning machine.

[0013] Preferably, the connecting assembly includes a positioning ring, an upper nut, a lower nut, and a washer. The positioning ring has a third sliding hole at its center, and the positioning post is movably connected to the third sliding hole. The upper nut has a first thread inside, and the positioning post is movably connected to the upper nut through the first thread. The washer is located between the positioning ring and the lower nut. The lower nut has a second thread inside, and the positioning post is movably connected to the lower nut through the second thread. The upper nut and the lower nut can fix and lock the position of the positioning ring.

[0014] The present invention has the following beneficial effects:

[0015] 1. In this invention, the traditional tablet pressing mechanism uses a locking sliding mechanism to move the pressing ring, which is laborious and has low adjustment accuracy. The improved tablet pressing mechanism has a slide rail inside the cylindrical shaft. The slide frame slides with the slide rail to move the pressing ring, which is labor-saving and flexible. The spacing between the external locking frames is determined according to the width of the second support piece, which makes it convenient to lock the position of the second support piece during the unwinding process. While limiting the position, it is convenient to control the flexibility and avoid slippage and fall off due to excessive flexibility.

[0016] 2. In this invention, the traditional yarn hanging mechanism uses a single support piece, and the yarn unwinding is achieved by changing the angle of the support piece through the up and down movement of the pressure ring. The function is limited, resulting in a lack of variety in the unwinding method and an inability to adapt to diverse application scenarios. The improved yarn hanging mechanism uses a method in which the first and second support pieces rotate in coordination, which greatly enhances the diversity of unwinding methods. At the same time, in order to ensure that the pressure ring maintains control over the second support piece during the movement, a bracket is designed on the outside of the pressure ring to limit the position of the second support piece, making the yarn hanging mechanism more functional and stable in use.

[0017] 3. In this invention, the steel ball cup and the positioning post are rotatably and slidably connected, which facilitates unwinding. The internal retaining ring ensures that the positioning post is in a stable rotation and sliding process. The bushing protects the part where the spiral rod and ratchet are spirally connected. The sliding fit between the connecting ring and the connecting post facilitates the replacement of bushings of different sizes. The dust cover, dust cap and spacer provide targeted dust protection for the main rotating parts to ensure a dust-free working environment. The two work together to enhance the limiting protection of the middle section of the positioning post.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] See Figure 1—8. This invention relates to a spindle for a textile machine. The spindle includes a positioning column 1, a cylindrical shaft 5, a pressing mechanism and a yarn hanging mechanism mounted on the cylindrical shaft 5, and a protective mechanism mounted on the positioning column 1. The pressing mechanism includes a slide 6, a pressing ring 7, and four brackets 8. The pressing ring 7 has a frustum-shaped structure and is hollow inside. The cylindrical shaft 5 has two slides on its side wall, symmetrically arranged along the central axis. The two slides 6 are movably connected to the two slides on the side closest to the cylindrical shaft 5, and the other ends of the two slides 6 are connected to the inner side wall of the pressing ring 7. Four brackets 8 are symmetrically arranged on the outer side wall of the pressing ring 7 along the central axis. The yarn hanging mechanism includes a rotating shaft 9, a first support plate 10, a second support plate 11, and a rotating column 12. The two rotating shafts 9 are respectively located inside the two slides and on the side away from the positioning column 1. The two first support plates 10 are movably connected to the two rotating shafts 9, and the two second support plates 11 are movably connected to the two rotating shafts 9. The plate 11 has four rotating holes at corresponding positions. Four rotating columns 12 are respectively set on the side walls of the two first support plates 10 along the central axis. The other ends of the four rotating columns 12 are movably connected to the four rotating holes. The limiting protection mechanism includes a steel ball cup 14, a retaining ring 15, a connecting column 16, a connecting ring 17, a connecting rod 18, and a bushing 19.

The steel ball cup 14 has a first sliding hole at the center of its interior. The positioning column 1 is movably connected to the first sliding hole. Two connecting columns 16 are symmetrically set on the inner side walls of the steel ball cup 14 along the central axis. The other ends of the two connecting columns 16 are respectively connected to the side walls of the two retaining rings 15. Two connecting rings 17 are movably connected to the two connecting columns 16. Two connecting rods 18 are symmetrically set above the bushing 19 along the central axis. The other ends of the two connecting rods 18 are respectively connected to the circumferential side of the two connecting rings 17.

[0034] Furthermore, the positioning post 1 also includes a spiral rod 2, a ratchet 3, and a support ring 4. The spiral rod 2 is located below the positioning post 1, and the other end of the spiral rod 2 is movably connected to the ratchet 3. The support ring 4 is located on the side of the ratchet 3 away from the positioning post 1. The movable connection between the spiral rod 2 and the ratchet 3 realizes the locking of the position of the positioning post 1 and the cylindrical shaft 5, and at the same time facilitates the replacement of different positioning posts 1.

[0035] Furthermore, the cylindrical shaft 5 also includes a conical ring 13, which is located on the side of the cylindrical shaft 5 away from the positioning post 1. The conical ring 13 mainly provides the necessary gravity support for the cylindrical shaft 5.

[0036] Furthermore, the positioning column 1 also includes a dustproof component, which is located outside the limit protection mechanism and provides necessary dustproof technical support for the internal core part.

[0037] Furthermore, the dustproof assembly includes a dust cover 20, a dust cap 21, a limiting ring 22, and a spacer 23. The dust cover 20 has an internal hollow structure. The dust cap 21 has a second sliding hole at its center. The positioning post 1 is movably connected to the second sliding hole. The limiting ring 22 is located on the upper part of the outside of the dust cover 20. The spacer 23 is located between the dust cover 20 and the positioning post 1, and the spacer 23 is movably connected to the positioning post 1. The design of the spacer 23 is to make the internal dustproof treatment more rigorous, and to facilitate the rotation of the positioning post 1.

[0038] Furthermore, the steel ball cup 14 includes a top frame 24. Two top frames 24 are symmetrically arranged on the inner side wall of the steel ball cup 14 along the central axis. The other end of each top frame 24 is connected to the inner side wall of the dust cover 20. The design of the top frame 24 can increase the connection stability between the dust cover 20 and the steel ball cup 14.

[0039] Furthermore, the positioning post 1 also includes a connecting component, which is disposed on the side wall of the positioning post 1. The connecting component is mainly for facilitating the connection and use of a spindle device for textile machines with a spinning machine.

[0040] Furthermore, the connecting assembly includes a positioning ring 25, an upper nut 26, a lower nut 27, and a washer 28. The positioning ring 25 has a third sliding hole at its center, and the positioning pin 1 is movably connected to the third sliding hole. The upper nut 26 has a first thread inside, and the positioning pin 1 is movably connected to the upper nut 26 through the first thread. The washer 28 is located between the positioning ring 25 and the lower nut 27. The lower nut 27 has a second thread inside, and the positioning pin 1 is movably connected to the lower nut 27 through the second thread. The upper nut 26 and the lower nut 27 can fix and lock the position of the positioning ring 25.

[0041] The working principle of this invention is as follows: the steel ball cup 14 and the positioning post 1 are rotatably and slidably connected, facilitating unwinding. The internal retaining ring 15 ensures that the positioning post 1 is in a stable rotation and sliding process. The bushing 19 protects the part where the spiral rod 2 and ratchet 3 are spirally connected. The sliding fit between the connecting ring 17 and the connecting post 16 facilitates the replacement of bushings 19 of different sizes. The dust cover 20, dust cap 21, and spacer 23 provide targeted dust protection for the main rotating parts, ensuring a dust-free working environment. The combination of these two elements enhances the limiting protection of the middle section of the positioning post 1. While ensuring that the middle section of the positioning post 1 is in a stable state of rotation and sliding, the moving pressure ring 7 is moved upwards. To facilitate sliding, a slide rail is provided inside the cylindrical shaft 5. The slide 6 slides in cooperation with the slide rail to move the pressure ring 7. The spacing between the external clamps 8 is determined according to the width of the second support piece 11, which facilitates locking the position of the second support piece 11 during unwinding. To address the issue of the limited functionality of the support pieces, the improved yarn hanging mechanism adopts a rotating cooperation between the first support piece 10 and the second support piece 11. At the same time, to ensure that the pressure ring 7 maintains control over the second support piece 11 during movement, clamps 8 are designed on the outside of the pressure ring 7 to limit the position of the second support piece 11, making the yarn hanging mechanism more versatile and facilitating yarn switching and unwinding.
