Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a spindle structure of a winding machine. Background Art

[0002] A spindle is one of the primary components of a winding machine for twisting and winding. It is primarily composed of a slender rotating shaft supported at two points. Spindles are found on roving frames, spinning frames, and twisting machines. A roving spindle is a round steel rod with a groove at the top to support and rotate the flyer. A spindle foot oiler is located at the tip of the spindle, and a spindle sleeve in the middle serves as the upper bearing for the spindle. A spinning spindle consists of a spindle shaft, spindle liner, spindle hook, spindle disc, and spindle foot. The quality of a spindle is closely related to yarn quality, power consumption, environmental noise, and labor productivity.

[0003] The spindle rotates the bobbin, which is fixed to the spindle shaft. As the bobbin rotates, it stretches and winds the yarn. In current spinning machines, the bobbin and spindle are typically connected as follows: the bobbin is plugged into the spindle shaft, where friction from the spindle shaft's upper conical surface drives the rotation. The diameter and taper of the mating area between the bobbin and the spindle shaft must ensure sufficient friction torque while facilitating insertion and removal of the bobbin. However, at high speeds, vibrations can occur between the spindle and the bobbin. This vibration can cause the bobbin to bounce up and down and impact the spindle disc. This not only significantly increases noise and spindle bearing load, but also leads to excessive wear on the spindle tip, reducing spinning efficiency.

[0004] The patent with application number CN202020795865.2 discloses a spindle for a spinning machine, including a spindle rod, a spindle core, a spindle hook, a spindle disk and a spindle foot. A cylindrical groove is opened on the spindle rod, and the groove is opened toward the top of the spindle rod. The axis of the groove forms an angle of 45° with the axis of the spindle rod. The groove is symmetrically arranged with the spindle rod as the center line. The distance from the opening of the groove to the axis of the spindle rod is less than the radius of the spindle rod. A spring is welded to the bottom surface of the groove, and a slider is welded to the front end of the spring. The slider is slidably connected to the groove. The length of the slider is less than the depth of the groove. The slider is bonded to the friction layer on one side of the groove opening. In the static state, since the opening of the groove is inclined upward after the spindle rod is installed, dust and impurities are easily trapped in the groove; during the rotation process, the slider is affected by the centrifugal force and the spring force, extending toward the opening of the groove, and the friction layer contacts the yarn tube to generate an extrusion force on the yarn tube. Since the opening of the groove is inclined upward, the extrusion force of the friction layer on the yarn tube is inclined upward, and a part of the pressure component will form a thrust to push the yarn tube upward. At high speeds, the yarn tube has a tendency to jump upward, increasing the risk of the yarn tube falling off the spindle. Utility Model Content

[0005] Based on this, it is necessary to provide a spindle structure for a winding machine in response to the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a spindle structure of a winding machine, including a spindle rod, the spindle rod having a conical surface, a plurality of hidden holes being opened on the conical surface, the angle a between the axis of the hidden hole and the axis of the spindle rod being greater than 90 degrees, a guide ring plate being fixed in the hidden hole, a movable column being inserted in the guide ring plate, a limiting plate being fixed at one end of the movable column facing toward the axis of the spindle rod, an extrusion plate being fixed at one end of the movable column facing away from the axis of the spindle rod, an elastic part being mounted on the movable column, one end of the elastic part being connected to the guide ring plate, and the other end of the elastic part being connected to the limiting plate, the elastic part providing a thrust to the limiting plate so that the limiting plate has a tendency to move toward the depth direction of the hidden hole, so that the extrusion plate can be contracted in the hidden hole in a natural state.

[0007] Optionally, the blind hole includes a first stepped hole and a second stepped hole sequentially connected from the outside to the inside, the aperture of the first stepped hole is larger than the aperture of the second stepped hole, and the guide ring plate is fixed in the first stepped hole.

[0008] Optionally, in a natural state, one end of the extrusion plate facing the axis of the spindle rod abuts against the guide ring plate, and / or one end of the limiting plate facing the axis of the spindle rod abuts against the bottom of the blind hole.

[0009] Optionally, the guide ring plate is provided with a ring groove adapted to the extrusion plate, and in a natural state, a portion of the extrusion plate is accommodated in the ring groove.

[0010] Optionally, the elastic member is a compression spring.

[0011] Optionally, the hidden holes are arranged in multiple layers on the conical surface, and the hidden holes in the same layer are distributed circumferentially on the spindle rod.

[0012] The beneficial effects of this technical solution are as follows: when the spindle rod rotates, after the centrifugal force overcomes the elastic force of the elastic part, the extrusion plate extends the hidden hole under the action of the centrifugal force and contacts the inner wall of the yarn tube, thereby increasing the friction between the yarn tube and the spindle rod, so that the yarn tube is stably inserted on the spindle rod; since the angle a between the axis of the hidden hole and the axis of the spindle rod is greater than 90 degrees, the opening of the hidden hole is downward, which can reduce the entry of dust and impurities, and the extrusion force of the extrusion plate on the yarn tube is inclined downward, and a part of the pressure component will form a thrust to push the yarn tube downward, so that the yarn tube is stably inserted on the spindle rod, avoiding the yarn tube from jumping upward and reducing the risk of the yarn tube detaching from the spindle.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See also Figures 1 to 4 An embodiment of the present application provides a spindle structure of a winding machine, including a spindle rod 1, the spindle rod 1 having a conical surface 2, and the spindle structure also includes a spindle core, a spindle hook, a spindle disk and a spindle foot, all of which are not shown. The above are all existing technologies and will not be repeated here.

[0020] In this embodiment, a plurality of hidden holes 3 are opened on the conical surface 2, and the hidden holes 3 are arranged in multiple layers on the conical surface 2. The hidden holes 3 in the same layer are distributed circumferentially on the spindle rod 1. In this embodiment, the number of hidden holes 3 in the same layer is four, and it can also be set to three or two in other implementations. The angle a between the axis of the hidden hole 3 and the axis of the spindle rod 1 is greater than 90 degrees and less than 120 degrees. In this embodiment, a is set to 91 degrees. A guide ring plate 4 is fixed in the hidden hole 3, and a movable column 5 is inserted in the guide ring plate 4. The end of the movable column 5 facing the axis of the spindle rod 1 is fixed with a limit plate 6, and the end of the movable column 5 facing away from the axis of the spindle rod 1 is fixed with an extrusion plate 7. An elastic part 8 is set on the movable column 5. The elastic part 8 is a compression spring. One end of the elastic part 8 is connected to the guide ring plate 4, and the other end of the elastic part 8 is connected to the limit plate 6. The elastic part 8 provides a thrust to the limit plate 6 so that the limit plate 6 has a tendency to move in the depth direction of the hidden hole 3, so that the extrusion plate 7 is retracted in the hidden hole 3 in a natural state.

[0021] To facilitate the installation of the guide ring plate 4, a concealed hole 3 is provided including a first step hole 9 and a second step hole 10 connected in sequence from the outside to the inside. The aperture of the first step hole 9 is larger than the aperture of the second step hole 10, and the guide ring plate 4 is fixed in the first step hole 9. Before installing the guide ring plate 4, first fix the extrusion plate 7 on the movable column 5 by welding, then insert the movable column 5 into the guide ring plate 4, install the elastic part 8 on the movable column 5, and fix the limit plate 6 on the movable column 5 by welding, so that the two ends of the elastic part 8 are respectively connected to the limit plate 6 and the guide ring plate 4. At this time, the guide ring plate 4, the movable column 5, the limit plate 6, the extrusion plate 7 and the elastic part 8 constitute an assembly; then insert the limit plate 6 into the blind hole 3, the limit plate 6 enters the second step hole 10, and the guide ring plate 4 abuts against the steps of the first step hole 9 and the second step hole 10 to realize the positioning of the installation position. At this time, the guide ring plate 4 is completely retracted into the first step hole 9, and there is still a welding distance between the front end face of the guide ring plate 4 and the conical surface 2. Then, the guide ring plate 4 is welded and fixed in the first step hole 9, the weld is polished, and the installation is completed. In order to facilitate welding the guide ring plate 4 with a welding gun, a ring groove 11 is provided on the guide ring plate 4 to match the extrusion plate 7. In a natural state, a portion of the extrusion plate 7 is accommodated in the ring groove 11. In this way, the front end of the guide ring plate 4 can be as close as possible to the opening of the blind hole 3 while ensuring the thickness of the extrusion plate 7, making it easier for the welding gun to weld the guide ring plate 4 to the ingot rod 1.

[0022] In the natural state, one end of the extrusion plate 7 facing the axis of the spindle rod 1 abuts against the guide ring plate 4, and / or one end of the limiting plate 6 facing the axis of the spindle rod 1 abuts against the bottom of the blind hole 3. In this embodiment, in the natural state, one end of the extrusion plate 7 facing the axis of the spindle rod 1 abuts against the guide ring plate 4, and one end of the limiting plate 6 facing the axis of the spindle rod 1 abuts against the bottom of the blind hole 3, thereby limiting the extrusion plate 7 and preventing the extrusion plate 7 from extending out of the blind hole 3 and affecting the installation of the bobbin.

[0023] The working principle of this embodiment is as follows:

[0024] In its natural state, see Figure 1 and Figure 2 , the spindle rod 1 does not rotate. Under the elastic force of the elastic member 8, the squeezing plate 7 is completely retracted in the dark hole 3, so that the bobbin 12 can be smoothly inserted into the spindle rod 1 and the bobbin 12 can be smoothly pulled out of the spindle rod 1 without the squeezing plate 7 getting stuck in the bobbin 12;

[0025] After the spindle rod 1 rotates, it drives the bobbin 12 to rotate. Figure 4Under the action of centrifugal force, the movable column 5, the limiting plate 6, the squeezing plate 7 and the elastic part 8 move outward. After the centrifugal force overcomes the elastic force of the elastic part 8, the elastic part 8 is compressed, causing the squeezing plate 7 to extend out of the dark hole 3 and contact the inner wall of the bobbin 12, increasing the friction between the bobbin 12 and the spindle rod 1, so that the bobbin 12 is stably inserted on the spindle rod 1; since the angle a between the axis of the dark hole 3 and the axis of the spindle rod 1 is greater than 90 degrees, the opening of the dark hole 3 is facing downward, which can reduce the entry of dust and impurities, and the squeezing force of the squeezing plate 7 on the bobbin 12 is inclined downward, and a part of the pressure component will form a thrust to push the bobbin 12 downward, so that the bobbin 12 is stably inserted on the spindle rod 1, avoiding the bobbin 12 jumping upward and reducing the risk of the bobbin 12 falling off the spindle.
