Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a yarn tube fixer for a spinning machine. Background Technology

[0002] Textile machinery is key equipment used in the production of textiles, encompassing multiple stages such as spinning, weaving, and dyeing. Among these, spinning machinery is primarily used to process fibers into yarn, while the yarn bobbin is an important component used to store the yarn during the spinning process.

[0003] Copper bushings are commonly used for lubrication and securing mechanical parts due to their excellent thermal conductivity and ductility. However, copper bushings have relatively poor wear resistance and are prone to wear problems in high-speed machinery.

[0004] Wear and tear on mechanical components is a common problem in mechanical engineering, especially in high-load, high-speed environments. Wear leads to increased clearance between parts, which in turn affects the precision and stability of the machinery. In textile machinery, this wear can cause the yarn bobbin holder to fail, impacting yarn quality and production efficiency.

[0005] The original design used a copper bushing to achieve the function of the retainer. However, the copper bushing is prone to wear after a period of use, which manifests as large wobbling of the yarn tube, easy falling off, and may cause the yarn to be sucked into the tube.

[0006] Due to the aforementioned problems, textile workers frequently need to reposition (re-fix or replace) yarn bobbins during operation, which increases the complexity and labor intensity of the operation. Therefore, this application provides a yarn bobbin holder for use on spinning machines. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a yarn tube retainer for spinning machines, solving the problem of using copper bushings in the original design to achieve the retainer function. However, copper bushings are prone to wear after a period of use, resulting in significant yarn tube wobbling, easy detachment, and potential yarn being sucked into the tube.

[0008] The present invention relates to a yarn tube fixer for a spinning machine, comprising a base plate for support, wherein a plurality of limiting components are provided at equal intervals along the edge of the base plate for fixing the yarn tube.

[0009] The base plate includes a plate body, and an annular groove is provided in the top center of the plate body. A telescopic component is installed in the annular groove, and the telescopic component is adapted to a limiting component arranged at the edge of the base plate.

[0010] The limiting component includes an arc-shaped plate that is adapted to the annular groove. A vertical plate is provided on the top of the arc-shaped plate, and the vertical plate is in contact with the inner wall of the yarn tube.

[0011] As a further improvement of this utility model, a protruding ring is provided at the bottom of the plate, and a ball bearing is installed at the protruding ring for fixing the plate to the spinning machine.

[0012] As a further improvement of this utility model, a support shaft is provided at the top center of the plate body. The support shaft is inserted into the middle of the yarn tube and supports the yarn tube in conjunction with the ball bearing and the plate body.

[0013] As a further improvement of this utility model, a vertically downward sliding groove is provided on the outer side of the arc-shaped plate, and a slider is installed in the sliding groove. The slider is slidably connected to the inner wall of the yarn tube.

[0014] As a further improvement of this utility model, a plug-in frame is provided at the lower outer end of the arc-shaped plate, and support members are provided on both sides of the inner wall of the plug-in frame to allow the arc-shaped plate to be flipped, so as to adjust the angle of the arc-shaped plate.

[0015] As a further improvement of this utility model, the plug-in frame includes a frame body, the inner side of which is provided with an installation groove, and the support member is disposed inside the installation groove.

[0016] As a further improvement of this utility model, the support member includes connecting rods, there are at least two connecting rods, and they are arranged in a mirror symmetrical manner. One end of the connecting rod is provided with a limit spring, and the other end is adapted to the arc plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model effectively reduces the shaking and deformation of the yarn tube during the spinning process by tightly fitting the base plate, arc plate and vertical plate, ensuring the quality of the yarn and production efficiency. The combination of the convex ring and the ball bearing allows the plate to be firmly fixed on the spinning machine, avoiding shaking during high-speed operation and enhancing the overall stability.

[0019] The telescopic components and curved plates allow the equipment to adapt to yarn tubes of different sizes and shapes. By adjusting the fixing force, it effectively meets diverse application needs, improving the versatility and flexibility of the equipment. The slider and groove ensure that the friction force is kept within a reasonable range during sliding, reducing wear on the inner wall of the yarn tube and helping to extend the service life of the equipment. The design of the curved plate fitting against the inner wall of the yarn tube generates a resistance force against the inner wall of the yarn tube, enhancing the stability of the connection and preventing the yarn tube from being sucked into the pipeline during spinning, reducing yarn waste and equipment failure rate.

[0032] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0033] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] like Figures 1 to 4 As shown, the yarn tube fixer for a spinning machine provided in this application includes a base plate 1 for support, and a plurality of limiting components 2 are provided at equal intervals on the edge of the base plate 1 for fixing the yarn tube.

[0035] The base plate 1 includes a plate body 11. A ring groove is provided in the middle of the top of the plate body 11. An expansion joint 4 is installed in the ring groove. The expansion joint 4 is adapted to the limiting component 2 arranged at the edge of the base plate 1.

[0036] In some embodiments, the limiting component 2 includes an arc-shaped plate 21, which is adapted to the annular groove. A vertical plate 22 is provided on the top of the arc-shaped plate 21, and the vertical plate 22 is attached to the inner wall of the yarn tube.

[0037] The arc of the arc plate 21 is matched with the outer contour of the yarn tube to ensure a tight fit when fixing the yarn tube and reduce shaking.

[0038] The upright plate 22 is made of a material that can provide soft support when it is in contact with the inner wall of the yarn tube, such as a thin steel plate, which has a certain degree of elasticity to prevent the yarn tube from deforming.

[0039] The top of the upright plate 22 is designed with a guide groove to facilitate the insertion and removal of the yarn tube, while reducing friction during operation.

[0040] The design of the upright plate 22 and the guide groove makes the insertion and removal of the yarn tube more convenient and quick, reducing operation time and labor intensity. The tightly fitting arc-shaped plate 21 and upright plate 22 design effectively prevent the yarn tube from being sucked into the pipeline during spinning, reducing yarn waste and equipment failure rate.

[0041] It should be noted that the base plate 1 adopts an integrated design and can be made of aluminum alloy. A ring groove is set in the middle of the top of the plate 11 to ensure that the telescopic component 4 can move smoothly.

[0042] The telescopic component 4 is designed to ensure the proper assembly of the arc-shaped plate 21 and the annular groove. Therefore, it consists of an inner core and an outer sleeve. The inner core is cylindrical, and the outer sleeve is cylindrical. The inner core and outer sleeve are connected by a helical spring, allowing the inner core to extend and retract freely within the sleeve. Furthermore, the design of the telescopic component 4 automatically adjusts the fixing force according to the size of the yarn tube, ensuring that the yarn tube does not shake or fall off during spinning.

[0043] The top of the inner core is designed with anti-slip texture to increase friction with the curved plate 21 and ensure the stability of the telescopic component 4 when fixing the yarn tube.

[0044] The adaptation of the telescopic component 4 and the arc plate 21 enables the yarn tube fixer to adapt to yarn tubes of different sizes and shapes, improving the flexibility of the equipment.

[0045] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The bottom of the plate 11 is provided with a protruding ring 13, and a ball bearing is installed at the protruding ring 13 for fixing the plate 11 on the spinning machine.

[0046] A support shaft 12 is provided at the top center of the plate 11. The support shaft 12 is inserted into the middle of the yarn tube. The bottom of the support shaft 12 is connected to the plate 11 through a ball bearing 3. The support shaft 12, together with the ball bearing 3 and the plate 11, supports the yarn tube.

[0047] The convex ring 13 is located at the bottom of the plate 11 and adopts a ring structure. Its diameter is smaller than the width of the plate 11, which provides additional support area for the plate 11 and increases the stability of the fastener.

[0048] The ball bearing 3 is installed inside the convex ring 13 and is combined with the position of the yarn tube installed on the spinning machine. The support shaft 12 is located at the top center of the plate 11. It is a cylindrical structure with a diameter smaller than the inner diameter of the yarn tube, ensuring that it can provide stable support when inserted into the middle of the yarn tube.

[0049] Furthermore, the ball bearing 3 allows the support shaft 12 to rotate freely in the vertical direction, reducing friction during yarn tube rotation and ensuring smooth rotation of the support shaft 12.

[0050] By combining the convex ring 13 and the ball bearing shaft, the plate 11 can be firmly fixed on the spinning machine, avoiding the shaking of the plate 11 during high-speed operation and enhancing the overall stability of the yarn tube holder.

[0051] Please see Figures 1 to 7 A vertically downward sliding groove 23 is provided on the outer side of the upright plate 22, and a slider 24 is installed at the sliding groove 23. The slider 24 is slidably connected to the inner wall of the yarn tube.

[0052] A plug-in frame 25 is provided at the lower outer side of the upright plate 22. Support members are provided on both sides of the inner wall of the plug-in frame 25 to allow the curved plate 21 to be flipped, so as to adjust the angle of the curved plate 21.

[0053] The groove 23 is formed on the outer side of the upright plate 22, pointing vertically downwards. The size of the slider 24 matches the groove 23 to ensure that the slider 24 will not disengage from the groove 23 during sliding. The surface of the slider 24 is designed with fine anti-slip textures to increase the friction with the inner wall of the yarn tube and prevent the yarn tube from sliding during high-speed rotation.

[0054] The plug-in frame 25 is located at the lower outer side of the upright plate 22. It has a U-shaped structure and the inner walls of the frame are equipped with support members on both sides to support and fix the arc plate 21.

[0055] The arc plate 21, supported by the support member, can be freely rotated within a certain angle range to adapt to yarn tubes of different sizes and shapes, fits against the inner side of the yarn tube, and due to the rotational characteristics, after being fixed with the yarn tube, it generates a force that resists the inner wall of the yarn tube, thereby better ensuring the connection stability of the yarn tube.

[0056] The design of the groove 23 and the slider 24 allows the vertical plate 22 to fit tightly against the inner wall of the yarn tube, providing stable support, reducing the shaking and deformation of the yarn tube during the spinning process, and ensuring the quality of the yarn and production efficiency.

[0057] The design of the plug-in frame 25 and the support allows the arc plate 21 to rotate freely within a certain angle range, which can adapt to yarn tubes of different sizes and shapes, improving the versatility and flexibility of the yarn tube fixator.

[0058] In some embodiments, the plug-in frame 25 includes a frame 251, and a mounting groove 253 is provided on the inner side of the frame 251, with a support member disposed on the inner side of the mounting groove 253.

[0059] The support includes a connecting rod 252, at least two of which are arranged in a mirror symmetrical manner. One end of the connecting rod 252 is provided with a limit spring, and the other end is adapted to the arc plate 21.

[0060] A spring is provided at one end of the connecting rod 252, allowing the connecting rod 252 to extend and retract freely within a certain range. This ensures that the arc plate 21 receives appropriate support when flipping, while reducing the impact force between the arc plate 21 and the frame 251. The spring is installed using an embedded design, ensuring that the spring will not detach from the connecting rod 252 during use, and also facilitating replacement and maintenance.

[0061] The other end of the connecting rod 252 is adapted to the arc-shaped plate 21 and is designed as a cylindrical protrusion with a polished surface, resulting in a low coefficient of friction. The top of the connecting rod 252 is designed with anti-slip texture to increase friction with the arc-shaped plate 21 and ensure that the arc-shaped plate 21 does not slip when flipped.

[0062] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
