Description

Technical Field

[0001] This utility model relates to the field of belt pulley disassembly technology, specifically to the disassembly of the pulley of a twisting machine. Background Technology

[0002] The pulley of the twisting machine is fixed to the drive shaft by keyway or interference fit. After long-term use, it is easy to need to be replaced due to wear or aging. The traditional disassembly and assembly method is to use pullers for disassembly and assembly.

[0003] However, in the process of removing the pulley from the pulley of a doubler twister in the existing technology, the top shaft in the middle of the pulley is usually directly pressed against one end of the doubler twister's drive shaft. When the screw in the middle of the pulley is rotated, the lower end of the screw will rotate relative to one end of the doubler twister's drive shaft, which can easily cause wear on one end of the doubler twister's drive shaft, affecting the appearance of the doubler twister's drive shaft. In addition, the worn end of the drive shaft is prone to corrosion, reducing the service life of the drive shaft.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a puller for removing the pulley of a twisting machine, so as to solve the problem mentioned in the background art that the puller for removing the pulley of a twisting machine easily causes wear on the end of the drive shaft of the twisting machine, which easily leads to rust on the end of the drive shaft and affects the appearance of the drive shaft.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Removing the pulley from the doublerer belt pulley includes:

[0008] The pull-out assembly includes a threaded rod located at one end of the twister drive shaft for providing support for the pulley removal operation, and a pull rod located outside the threaded rod for pulling the pulley component out from the outside of the twister drive shaft;

[0009] An ejector assembly is located at one end of the threaded rod on the drive shaft of the two-twist machine and serves as an ejector assembly for transitioning the threaded rod to the drive shaft of the two-twist machine.

[0010] Furthermore, the ejection component includes:

[0011] A rotating sleeve is rotatably fitted onto the lower end of the threaded rod. The rotating sleeve has a receiving groove inside, and the inner wall of the receiving groove has an internal thread near the upper part.

[0012] The transition mechanism is rotatably connected inside the receiving groove;

[0013] A limiting sleeve, threadedly connected inside the receiving groove, is used to limit the transition mechanism inside the receiving groove. The limiting sleeve has an inner hole for penetrating the threaded rod, the inner diameter of which is adapted to the outer diameter of the threaded rod. The limiting sleeve has an outer thread on its outer side for adapting to the internal thread of the receiving groove.

[0014] Furthermore, the transition mechanism includes:

[0015] A limiting block is fixedly connected to the lower end of the threaded rod. The outer diameter of the limiting block is adapted to the inner diameter of the receiving groove and is larger than the diameter of the lower part of the threaded rod. The limiting block is rotatably connected inside the receiving groove.

[0016] The lower ball bearing is embedded in the bottom of the limiting block and rotatably connected to the block, while its lower end is placed at the bottom of the receiving groove to reduce the friction between the limiting block and the receiving groove.

[0017] Furthermore, an upper ball is embedded in the upper part of the limiting circular block and on the outside of the threaded rod, and the upper ball is rotatably connected to the circular block;

[0018] The upper end of the upper ball contacts the lower end of the limiting sleeve to reduce the friction between the limiting block and the limiting sleeve.

[0019] Furthermore, the ejection component also includes:

[0020] A rubber pad is fixedly connected to the lower end of the rotating sleeve to provide a transition at the contact point between the rotating sleeve and the drive shaft of the twisting machine.

[0021] Furthermore, the pull component also includes:

[0022] The support sleeve is threadedly connected to the outside of the threaded rod;

[0023] The support arm is provided in three sets, corresponding one-to-one with the pull rod. One end of the support arm is hinged to the outside of the support sleeve, and the other end is hinged to the pull rod, which is used to adjust the position of the pull rod relative to the pulley component.

[0024] Furthermore, a rotating rod for adjusting the rotation of the threaded rod is fixedly inserted into the upper part of the threaded rod.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. This utility model provides an ejector assembly at one end of the threaded rod located on the transmission shaft of the twisting machine. During the disassembly process, when the threaded rod drives the belt pulley to move upward along the transmission shaft of the twisting machine via the pull rod, the ejector assembly provides a transition between the threaded rod and the transmission shaft of the twisting machine, preventing the threaded rod from rotating relative to one end of the transmission shaft of the twisting machine and causing wear on one end of the transmission shaft.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-7 This utility model provides a technical solution:

[0037] Removing the pulley from the doublerer belt pulley includes:

[0038] The pull-out assembly 1 includes a threaded rod 12 located at one end of the twister drive shaft 100 for providing support for the pull-out operation of the pulley, and a pull rod 15 located outside the threaded rod 12 for pulling the pulley 101 out from the outside of the twister drive shaft 100.

[0039] Ejector assembly 2 is located at one end of the threaded rod 12 on the transmission shaft 100 of the twister and is used to transition the threaded rod 12 to the transmission shaft 100 of the twister.

[0040] It should be noted that by setting the ejector assembly 2 at one end of the threaded rod 12 located on the transmission shaft 100 of the twister, when the threaded rod 12 drives the belt pulley 101 to move upward along the transmission shaft 100 of the twister for disassembly, the ejector assembly 2 provides a transition between the threaded rod 12 and the transmission shaft 100 of the twister, preventing the threaded rod 12 from rotating relative to one end of the transmission shaft 100 of the twister, thus preventing wear on one end of the transmission shaft 100 of the twister.

[0041] As an improvement, such as Figure 1-3 As shown, the ejection component 2 includes:

[0042] Rotating sleeve 21 is rotatably sleeved on the lower end of the threaded rod 12. The rotating sleeve 21 has a receiving groove 211 inside, and the inner wall of the receiving groove 211 has an internal thread near the upper part.

[0043] Transition mechanism 24 is rotatably connected inside the receiving groove 211;

[0044] The limiting sleeve 23 is threadedly connected inside the receiving groove 211 and is used to limit the transition mechanism 24 inside the receiving groove 211. The limiting sleeve 23 has an inner hole 231 for passing through the threaded rod 12. The inner diameter of the inner hole 231 is adapted to the outer diameter of the threaded rod 12. The limiting sleeve 23 has an outer thread 232 on the outside for adapting to the internal thread of the receiving groove 211.

[0045] Furthermore, such as Figure 3-7 As shown, the transition mechanism 24 includes:

[0046] A limiting block 241 is fixedly connected to the lower end of the threaded rod 12. The outer diameter of the limiting block 241 is adapted to the inner diameter of the receiving groove 211 and is larger than the diameter of the lower part of the threaded rod 12. The limiting block 241 is rotatably connected inside the receiving groove 211.

[0047] The lower ball bearing 242 is embedded in the bottom of the limiting block 241 and rotatably connected to the block, and its lower end is placed at the bottom of the receiving groove 211 to reduce the friction between the limiting block 241 and the receiving groove 211.

[0048] Furthermore, an upper ball bearing 243 is embedded in the upper part of the limiting circular block 241 and outside the threaded rod 12, and the upper ball bearing 243 is rotatably connected to the circular block;

[0049] The upper end of the upper ball 243 contacts the lower end of the limiting sleeve 23 to reduce the friction between the limiting block 241 and the limiting sleeve 23.

[0050] As an improvement, such as Figure 2-3 As shown, the ejection component 2 further includes:

[0051] Rubber pad 22 is fixedly connected to the lower end of the rotating sleeve 21 and is used to transition the contact between the rotating sleeve 21 and the transmission shaft 100 of the twisting machine.

[0052] Furthermore, such as Figure 1-2 As shown, the pull component 1 further includes:

[0053] The support sleeve 11 is threaded to the outside of the threaded rod 12, and the support sleeve 11 has a threaded hole 111 inside that is adapted to the outside of the threaded rod 12;

[0054] The support arm 14 is provided in three sets, corresponding one-to-one with the pull rod 15. One end of the support arm 14 is hinged to the outside of the support sleeve 11, and the other end is hinged to the pull rod 15, which is used to adjust the position of the pull rod 15 relative to the belt pulley component 101.

[0055] Furthermore, a rotating rod 13 for adjusting the rotation of the threaded rod 12 is fixedly inserted into the upper part of the threaded rod 12.

[0056] It should be added that the threaded rod 12 in this utility model is divided into two sections. The upper section is provided with a thread that matches the threaded hole 111, while the lower section is not provided with a thread and its diameter is smaller than that of the upper section.

[0057] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-3 As shown, the hooks corresponding to the three pull rods 15 are attached to the belt pulley 101 at one end of the twister. Rotating the rotating rod 13 causes the threaded rod 12 to rotate. The lower end of the threaded rod 12 is pressed against the upper end of the twister drive shaft 100 by the rotating sleeve 21 under the action of the rubber pad 22. At the same time, the threaded rod 12 drives the support sleeve 11 to move upward by the threaded tangential force between it and the threaded hole 111. The support sleeve 11 drives the pull rod 15 to move upward by the support arm 14. The pull rod 15 drives the belt pulley 101 to be pulled out along the twister drive shaft 100, thus completing the disassembly of the belt pulley 101.

[0058] like Figure 1-7As shown, when the rubber pad 22 is pressed against one end of the twister drive shaft 100 and the threaded rod 12 rotates, the threaded rod 12 drives the limiting block 241 to rotate relative to the rotating sleeve 21. The upper ball 243 of the upper part of the limiting block 241 rolls along the lower end of the limiting sleeve 23, and the lower ball 242 of the lower part of the limiting block 241 rolls along the bottom of the receiving groove 211. Meanwhile, the rotating sleeve 21 and the rubber pad 22 remain stationary relative to one end of the twister drive shaft 100, thus preventing the threaded rod 12 from wearing down one end of the twister drive shaft 100 during rotation and extending the service life of the twister drive shaft 100.
