Description

Technical Field

[0001] This utility model relates to a high-speed twisting spindle, belonging to the field of textile machinery technology. Background Technology

[0002] The spinning spindle is an important twisting and winding component on a ring spinning machine. The spindle mainly includes a spindle bar, a spindle disc connected to the spindle bar, and spindle feet. The power drives the spindle disc to rotate the yarn tube installed on the spindle disc, so as to achieve twisting and winding of the yarn.

[0003] Existing high-speed twisting spindles connect the spindle rod to the spindle disc, with the spindle rod mounted within the spindle foot assembly via bearings. For ring spinning machines producing certain special yarns, the total spindle length is relatively long. When the spindle rod length exceeds 600mm and the spindle rod diameter exceeds 35mm, the overall structure of the spindle rod results in significant material waste due to the large difference in diameter between the upper support bobbin and the connection point with the spindle foot. This not only increases processing difficulty but also significantly increases manufacturing, installation, and maintenance costs. Furthermore, existing spindle brakes are movably mounted between the spindle foot and the spindle support. By manually operating the brake handle, the braking unit contacts the brake disc outside the spindle disc, stopping the spindle rod from rotating. However, the brake block is located on the outer periphery of the spindle disc. During yarn twisting and winding, fly yarn occurs, accumulating in the gap between the brake block and the outer periphery of the spindle disc, affecting the braking effect. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed twisted spindle with a reasonable structure, which can reduce manufacturing and maintenance costs and has reliable braking.

[0005] The technical solution of this utility model to achieve the above-mentioned objective is: a high-speed twisted spindle, including a spindle foot assembly, a spindle disc and a spindle rod, characterized in that: the spindle rod is mounted on the spindle foot assembly through a spindle rod bearing and a lower shaft seat, the spindle rod extends out of the spindle foot tube and is connected to the spindle disc through a rotating shaft, and a spindle brake assembly is also provided between the spindle disc and the spindle foot tube;

[0006] The brake assembly includes a brake seat, a brake arm, a brake ring, a push ring, and two tension springs. The brake seat is connected to the foot tube of the foot assembly, and the outer periphery of the brake seat has two mating surfaces that mate with the fork on the brake arm and a notch at the mating surfaces.

[0007] The brake ring is composed of two semicircular rings joined together. The brake ring, which is fitted onto the foot tube, is located in the brake ring seat at the top of the brake seat and the brake ring seat at the bottom of the brake disc. Each semicircular ring of the brake ring has a symmetrical tension spring groove at the top that is not connected in the middle, and two symmetrical guide grooves with inclined surfaces at the bottom and a larger bottom and a smaller top in the bottom hole. The push ring is located at the bottom of the brake ring and can move inside the brake ring. Two inclined push plates on the push ring are located in the corresponding guide grooves of the brake ring. The inclined surfaces on the inclined push plates of the push ring are connected to the inclined surfaces of the guide grooves on the brake ring. Two tension springs are installed in the tension spring grooves where the two semicircular rings of the brake ring meet.

[0008] The upper part of the brake arm has a fork located at the mating surface of the brake seat. The lower part of the fork has a lower protrusion supported on the rib plate, and the top end has a push block. The push block is located at the corresponding notch of the brake seat and is opposite to the push ring. When the push block on the fork pushes the push ring upward, the inclined push plate on the push ring moves upward along the guide groove. The two semicircular rings of the brake ring expand and press against the inner wall of the brake ring seat of the brake disc to brake the brake disc. When the two semicircular rings of the brake ring disengage from the brake ring seat of the brake disc, the braking of the brake disc is released.

[0009] In this invention, the rotating shaft is connected to both the spindle rod and the spindle disc. Therefore, the spindle rod (connected to the small-diameter shaft of the spindle foot assembly) and the large-diameter rotating shaft (connected to the yarn package) are processed and installed separately, ensuring a reliable connection between the spindle rod, rotating shaft, and spindle disc. This facilitates processing and installation and significantly reduces manufacturing and maintenance costs. The invention places the brake assembly between the spindle foot tube and the spindle disc, with the brake ring positioned inside the spindle disc. By using a fork on the upper part of the brake arm to actuate the push ring, the two semicircular rings of the brake ring expand and press against the inner wall of the brake ring seat on the spindle disc, braking the spindle disc. Therefore, by placing the movable brake ring and push ring between the brake seat and the spindle disc, the amount of fly yarn entering is significantly reduced, resulting in a reasonable combination and improved braking performance. This invention also maintains braking torque by synchronously pushing the push ring along the inclined surface within the guide groove using a fork on the brake arm, thus improving braking reliability.

Detailed Implementation

[0018] See Figures 1-2 As shown, this utility model discloses a high-speed twisted spindle, comprising a spindle foot assembly 8, a spindle disc 3, and a spindle rod 9. (See attached image) Figure 2 As shown, the spindle rod 9 of this utility model is mounted on the spindle foot assembly 8 via the spindle rod bearing 8-2 and the lower shaft seat 8-6. The spindle rod 9 extends out of the spindle foot tube 8-4 and is connected to the spindle disc 3 via the rotating shaft 2. The rotating shaft 2 is used to install the bobbin and to twist and wind the yarn. A spindle brake assembly 6 is also provided between the spindle disc 3 and the spindle foot tube 8-4. When the yarn breaks, the spindle is braked by operating the spindle brake assembly 6, which facilitates the wiring operation.

[0019] See Figure 2As shown, the connecting shaft at the lower part of the rotating shaft 2 is installed at the connecting tapered hole of the spindle 3, and the inner tapered hole 2-2 of the rotating shaft 2 is installed at the upper part of the spindle rod 9, connecting the rotating shaft 2 to the upper middle part of the spindle 3. The top surface of the spindle 3 is connected to the limiting shoulder 2-3 on the rotating shaft 2, which quickly positions the axial direction of the rotating shaft 2. The upper part of the spindle 3 is provided with an upper convex ring 3-1, so the rotating shaft 2 is reliably connected to the spindle and the spindle rod 9, and the upper convex ring 3-1 supports the tube. The spindle belt part 3-2 of the spindle 3 is connected to the transmission belt, which drives the spindle 3 to rotate the rotating shaft 2 and the spindle rod 9. The spindle rod 9 is supported on the spindle foot assembly 8 and can also drive the tube to rotate, reducing the overall material consumption of the spindle rod and significantly reducing manufacturing and maintenance costs.

[0020] See Figure 1 , 2 As shown, the upper part of the rotating shaft 2 and the upper part of the limiting shoulder 2-3 of this utility model are provided with elastic support 1, and the elastic support 1 is evenly distributed in the radial direction. The elastic support 1 is composed of spring 1-1 and support cover 1-2. The rotating shaft 2 has spring holes 2-1 evenly distributed in the upper and lower parts. There can be 2 to 3 spring holes 2-1. The spring 1-1 and support cover 1-2 are set in the spring hole 2-1. The spring force acts on the support cover 1-2 to provide friction force to the tube, so that the tube can be reliably installed on the rotating shaft 2 and rotate together with the spindle 3.

[0021] As shown in Figures 1-6, the brake assembly 6 of this utility model includes a brake seat 6-3, a brake arm 6-1, a brake ring 6-2, a push ring 6-7, and two tension springs 6-6. The brake seat 6-3 is connected to the foot tube 8-4 of the foot assembly 8. The outer periphery of the brake seat 6-3 is provided with two mating surfaces 6-31 that mate with the fork 6-11 on the brake arm 6-1 and a notch 6-32 at the mating surface 6-31, so as to facilitate the installation of the fork 6-11 on the brake arm 6-1 at the mating surface 6-31 of the brake seat 6-3. By manipulating the brake arm 6-1, the push ring 6-7 is pushed to expand or close the brake ring 6-2, thereby realizing the braking or release of the brake.

[0022] As shown in Figures 1-6, the brake ring 6-2 of this invention is composed of two semi-circular rings joined together. The brake ring 6-2, fitted onto the foot tube 8-4, is located within the brake ring seat 3-3 at the upper part of the brake seat 6-3 and the lower part of the brake disc 3. The brake ring 6-2 can only move radially and not axially. The tops of the two semi-circular rings of the brake ring 6-2 are connected to the shoulders on the foot tube 8-4, or the shaft retaining ring 6-4 mounted on the foot tube 8-4 is connected to the tops of the semi-circular rings of the brake ring 6-2. The brake seat 6-3 is screwed onto the foot tube 8-4 and connected to the brake ring 6-2. The brake assembly 6 is easy and quick to install.

[0023] See Figures 1-6As shown, the upper part of each semicircular ring of the brake ring 6-2 of this utility model is provided with symmetrical tension spring grooves 6-21 that are not connected in the middle, and the lower hole is provided with two symmetrical guide grooves 6-23 with inclined surfaces, which are larger at the bottom and smaller at the top. The push ring 6-7 is set at the lower part of the brake ring 6-2 and can move within the brake ring 6-2. The two inclined push plates 6-71 on the push ring 6-7 are set in the corresponding guide grooves 6-23 of the brake ring 6-2. The inclined surfaces on the inclined push plates 6-71 on the push ring 6-7 are connected to the inclined surfaces of the guide grooves 6-23 on the brake ring 6-2. The two tension springs 6-6 are installed in the tension spring grooves 6-21 where the two semicircular rings of the brake ring 6-2 are connected. The tension springs 6-6 keep the brake ring 6-2 in a closed state, and when braking, they overcome the tension of the tension springs 6-6 to open the brake ring 6-2.

[0024] See Figure 1 , 2 As shown, the fork 6-11 on the upper part of the brake arm 6-1 of this utility model is located at the mating surface 6-31 of the brake seat 6-3. The fork 6-11 has a lower protrusion 6-12 supported on the reinforcing plate at its lower part, and a push block 6-13 at its top end. The push block 6-13 is located at the corresponding notch 6-32 of the brake seat 6-3, opposite to the push ring 6-7. When the spindle is mounted on the reinforcing plate of the ring spinning machine and the brake arm 6-1 is operated, the lower protrusion 6-12 of the fork 6-11 of the brake arm 6-1, supported on the reinforcing plate, serves as a support point, moving the push block 6-13 at the top end of the brake arm 6-1 upwards, thus pushing the push ring 6-7 along the guide groove 6. -23 moves upward, and the push block 6-13 on the shift fork 6-11 pushes the push ring 6-7 upward. The inclined push plate 6-71 on the push ring 6-7 moves upward along the guide groove 6-23. The two semicircular rings of the brake ring 6-2 expand and press against the inner wall of the brake ring seat 3-3 of the spindle disk 3 to brake the spindle disk 3. The brake ring 6-2 releases the brake on the spindle disk 3 when the two semicircular rings of the brake ring 6-2 disengage from the brake ring seat 3-3 of the spindle disk 3. Since the brake ring 6-2 is set inside the brake ring seat 3-3 of the spindle disk 3, it can reduce the accumulation of fly yarn in the brake ring 6-2. In particular, the inclined push plate 6-71 on the push ring 6-7 moves along the guide groove 6-23, which can improve the reliability of braking.

[0025] See Figure 2 , 6 As shown, the brake holder 6-3 of this utility model is provided with two symmetrical limiting posts 6-8. The two semi-circular rings of the brake ring 6-2 are provided with limiting grooves 6-22 at their ends that match the limiting posts 6-8. When the brake ring 6-2 is closed, the limiting posts 6-8 are set in the limiting holes formed by the limiting grooves 6-22 of the two semi-circular rings, ensuring the accuracy of the brake holder 6-3 after reset and realizing reliable braking of the spindle.

[0026] See Figure 3As shown, the tension spring grooves 6-21 on each semicircular ring of the brake ring 6-2 of this utility model include a circular tension spring end seat and a groove with a groove width smaller than the diameter of the tension spring end seat hole. The large ends of each tension spring 6-6 are set in the tension spring end seat, so that the tension spring 6-6 can be quickly installed in the tension spring groove 6-21 without affecting the normal operation of the tension spring 6-6. The cover plate 6-5 is installed in the plate groove of the brake ring 6-2 and blocks the two tension springs 6-6. The shaft retaining ring 6-4 installed on the spindle foot tube 8-4 is connected to the cover plate 6-5.

[0027] See Figure 5 As shown, the angle β between the inclined surface of the guide groove 6-23 on the brake ring 6-2 and the plane is 42±5°. If the angle β between the inclined surface of the guide groove 6-23 on the brake ring 6-2 and the plane is 45°, the inclined push plate 6-71 on the push ring 6-7 can move axially along the guide groove 6-23 without controlling the braking distance, thus achieving reliable braking. See... Figure 5 , 6 As shown, the brake ring 6-2 of this utility model is also provided with a stepped hole 6-24 for axially limiting the push ring 6-7, so that the push ring 6-7 can operate reliably. Figure 6 As shown, the push ring 6-7 of this utility model is symmetrically provided with two protruding lugs 6-72, and the lower part of the lugs 6-72 is provided with a slanted push plate 6-71, which can increase the contact area between the push block 6-13 and the push ring 6-7.

[0028] See Figure 1 , 2 As shown in Figure 4, the outer periphery of the brake seat 6-3 of this utility model is provided with a hook mounting groove 6-33. The lower part of the hook seat 5 is installed on the hook mounting groove 6-33 of the brake seat 6-3 by fasteners. The hook 4 is installed on the upper part of the hook seat 5 by fasteners. The hook 4 is located on the upper part of the brake ring seat 3-3 of the spindle 3, which prevents the spindle 3 from moving upward when the tube is removed.

[0029] See Figure 1 , 2As shown, the spindle foot assembly 8 of this utility model includes a spindle foot tube 8-4, an elastic tube 8-3 with a spiral groove, a shock-absorbing coil spring 8-5, and a lower shaft seat 8-6. The upper part of the elastic tube 8-3 is pressed onto the upper part of the spindle foot tube 8-4. A cavity is provided in the middle and lower parts of the spindle foot tube 8-4 and the elastic tube 8-3. The spindle rod 9 is mounted on the bearing seat of the spindle foot tube 8-4 through the spindle rod bearing 8-2. The bottom of the spindle rod 9 is installed in the lower shaft seat 8-6 with a cap. The lower shaft seat 8-6 is installed at the bottom of the elastic tube 8-3. The shock-absorbing coil spring 8-5 is disposed in the cavity between the spindle foot tube 8-4 and the elastic tube 8-3, which reliably mounts the spindle rod 9 on the spindle foot assembly 8 and allows it to rotate together with the rotating shaft 2. As shown in 2, 3, and 5, a bearing cover plate 8-1 is installed on the top of the spindle foot tube 8-4. The bearing cover plate 8-1 covers the spindle bearing 8-2, which can reduce the amount of fly yarn entering the bearing and improve the service life of the bearing. A spindle foot nut 7 is also installed on the lower part of the spindle seat 6-3 of the spindle foot tube 8-4. The spindle foot tube 8-4 is placed in the assembly hole of the stiffener plate and the spindle foot nut 7 is tightened to fix the spindle seat 6-3 on the spindle foot tube 8-4 and the spindle foot nut 7 on the stiffener plate.
