Description
Technical Field
[0001] The present invention relates to the technical field of wire winding and unwinding, and particularly to a stepless damping adjuster for wire winding and unwinding. Background Art
[0002] In existing wire winding and unwinding devices, the design of the damper is crucial for the stability and smoothness of wire winding and unwinding. Traditional dampers often adopt fixed damping or a limited number of levels of adjustment methods. This design may not be able to provide the best wire winding and unwinding experience when dealing with wires of different materials, thicknesses, or lengths. Especially in situations where the damping force needs to be adjusted frequently or the wire specifications vary, the limitations of traditional dampers are particularly obvious. On the one hand, the wire winding and unwinding device with fixed damping cannot be flexibly adjusted according to the actual situation of the wire, which may cause the wire to be too tight or too loose during winding and unwinding, affecting the arrangement and storage effect of the wire. On the other hand, although there are some wire winding and unwinding devices with adjustable damping on the market, they usually can only provide a limited number of levels of damping adjustment and cannot meet the user's demand for fine adjustment.
[0003] Therefore, there is an urgent need in the market for a wire winding and unwinding damper with a simple structure, easy to maintain, and capable of providing stepless damping adjustment function to meet the diverse needs of different users for the stability and smoothness of wire winding and unwinding.
[0004] The stepless damping adjuster for wire winding and unwinding proposed in this embodiment can not only achieve the function of steplessly adjusting the damping force, but also improve the stability and durability of the overall structure. Summary of the Invention
[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a stepless damping adjuster for wire winding and unwinding.
[0006] To achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A stepless damping adjuster for wire winding and unwinding, including a wire winding shaft. A support member is installed on the circumferential outer wall of the wire winding shaft, and a wire reel is sleeved on the circumferential outer wall of the wire winding shaft. One side outer wall of the wire reel abuts against the support member. A tightening assembly is also installed on the circumferential outer wall of the wire winding shaft. The tightening assembly includes a spring, a support bearing, and a tightening disc. The spring, the support bearing, and the tightening disc are all sleeved on the circumferential outer wall of the wire winding shaft, and the support bearing is installed between the tightening disc and the spring.
[0008] Preferably: The support member includes a fixing mechanism and a damping adjustment mechanism. The fixing mechanism includes a set screw and a fixing disc. The fixing disc is sleeved on the circumferential outer wall of the wire winding shaft, and the set screw is threadedly connected to the inner wall of the threaded hole opened on the circumferential outer wall of the fixing disc. The damping adjustment mechanism is movably connected to the circumferential outer wall of the wire winding shaft, and the damping adjustment mechanism and the fixing disc are fixed by bolts.
[0009] Preferably, a rotating disc is movably connected to the circumferential outer wall of the take-up spool, and a first bearing and a second bearing are installed between the circumferential outer wall of the take-up spool and the circumferential inner wall of the rotating disc.
[0010] Preferably, the damping adjustment mechanism includes an internal hexagonal set screw, a first spring, and a nylon column. The first spring and the nylon column are both movably connected to the inner wall of a threaded hole formed in the circumferential outer wall of the friction disc, and the internal hexagonal set screw is threadedly connected to the threaded hole.
[0011] Preferably, the side wall of the friction disc is provided with a mounting hole adapted to the bolt, and the side surface of the fixed disc is provided with a threaded hole adapted to the bolt.
[0012] Preferably, a snap ring is installed on the circumferential outer wall of the rotating disc.
[0013] Preferably, a limit set screw is fixed to the outer wall of one side of the rotating disc by a pin.
[0014] On the basis of the foregoing solution: a limit groove adapted to the outer diameter of the limit set screw is formed in the side wall of the wire reel.
[0015] The beneficial effects of the present invention are as follows:
[0016] 1. Through the design of the damping adjustment mechanism, the internal hexagonal set screw is used to apply pressure to the first spring, and then the nylon column is used to apply damping to the rotating disc, realizing stepless adjustment of the damping. This design enables, during the wire take-up and pay-out process, regardless of how the thickness of the metal wire changes, the appropriate take-up torque can be maintained by adjusting the damping, thereby improving the accuracy and stability of the wire take-up.
[0017] 2. Conventional wire take-up vehicles usually use high-cost torque motors to control the take-up torque, while this wire take-up and pay-out stepless damping adjuster realizes damping adjustment through a clever mechanical design, thus completely replacing the torque motor. This not only reduces the cost of the equipment but also improves the economic benefits. At the same time, since the torque range of the damper can be adjusted to a relatively large range (such as above 1 - 50 N), it can meet the take-up requirements of more types of metal wires.
[0018] 3. All components are mechanically connected, so they are more durable than electronic components and have lower maintenance costs. In addition, the disassembly and assembly of the equipment are relatively simple and convenient. Users can perform quick repairs or replace components as needed, thereby ensuring the continuous and stable operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0028] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation modes.
[0029] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.
[0030] Embodiment 1:
[0031] A stepless damping adjuster for wire winding and unwinding, such as Figures 1 to 8As shown in the figure, it includes a take-up spool 1. A support member is installed on the circumferential outer wall of the take-up spool 1. A wire reel 3 is sleeved on the circumferential outer wall of the take-up spool 1. One side outer wall of the wire reel 3 abuts against the support member. A tightening assembly is also installed on the circumferential outer wall of the take-up spool 1. The tightening assembly includes a spring 6, a support bearing 7, and a tightening disc 8. The spring 6, the support bearing 7, and the tightening disc 8 are all sleeved on the circumferential outer wall of the take-up spool 1, and the support bearing 7 is installed between the tightening disc 8 and the spring 6;
[0032] When wire winding and unwinding are required, the wire reel 3 can be used to wind the metal wire. The wire reel 3 can be installed on the take-up spool 1 by plugging. In the process of wire winding and unwinding, to ensure the stability of the wire reel 3, after sliding the tightening disc 8 along the take-up spool 1 so that the tightening disc 8 abuts against one end of the wire reel 3, the wire reel 3 is restricted between the support member and the tightening disc 8, thereby ensuring the stability of the wire reel 3 during wire winding and unwinding. After the tightening disc 8 abuts against one end of the wire reel 3, a clamp is installed at the end of the spring 6 away from the support bearing 7, and the spring 6 is squeezed by the clamp. In this process, the spring 6 is gradually compressed, so as to ensure that a certain pressure is maintained between the tightening disc 8 and the wire reel 3, thereby tightening the wire reel 3. By providing the support bearing 7, when the threaded ring 7 rotates, it is ensured that there is no relative rotation between the tightening disc 8 and the wire reel 3, reducing the friction between the tightening disc 8 and the wire reel 3.
[0033] The support member includes a fixing mechanism and a damping adjustment mechanism. The fixing mechanism includes a setscrew 4 and a fixing disc 5. The fixing disc 5 is sleeved on the circumferential outer wall of the take-up spool 1. The setscrew 4 is threadedly connected to the inner wall of a threaded hole opened on the circumferential outer wall of the fixing disc 5. The damping adjustment mechanism is slidably connected to the circumferential outer wall of the take-up spool 1, and the damping adjustment mechanism and the fixing disc 5 are fixed by a bolt 13;
[0034] When it is necessary to fix the fixing disc 5 and the take-up spool 1, first sleeve the fixing disc 5 on the circumferential outer wall of the take-up spool 1. When the fixing disc 5 moves to one end of the take-up spool 1, threadedly connect the setscrew 4 with the threaded hole on the circumferential outer wall of the fixing disc 5. As the setscrew 4 rotates continuously, one end of the setscrew 4 finally abuts against the circumferential outer wall of the take-up spool 1, thus completing the fixed connection between the take-up spool 1 and the fixing disc 5. By providing the bolt 13, the damping adjustment mechanism and the fixing disc 5 can be fixed.
[0035] A rotating disk 12 is rotatably connected to the outer circumferential wall of the wire take-up spool 1, and a first bearing 14 and a second bearing 15 are installed between the outer circumferential wall of the wire take-up spool 1 and the inner circumferential wall of the rotating disk 12. The damping adjustment mechanism includes an Allen head set screw 11, a first spring 17, and a nylon column 18. The first spring 17 and the nylon column 18 are both slidably connected to the inner wall of a threaded hole formed in the outer circumferential wall of the friction disk 2, and the Allen head set screw 11 is threadedly connected to the threaded hole. An installation hole adapted to the bolt 13 is formed in the side wall of the friction disk 2, and a threaded hole adapted to the bolt 13 is formed in the side surface of the fixed disk 5;
[0036] By means of the first bearing 14 and the second bearing 15, the rotating disk 12 can rotate relative to the wire take-up spool 1. By rotating the Allen head set screw 11, the Allen head set screw 11 applies a pressure to the first spring 17 during rotation. By using the transmissibility of force, the nylon column 18 applies damping to the outer circumferential wall of the rotating disk 12. When the wire reel 3 winds and unwinds the metal wire, due to the damping effect, no matter how thick or thin the metal wire is wound, the take-up torque can be adjusted to ensure that the physical properties of the metal wire are not damaged. In addition, because of the low-cost use of the damper, it can completely replace the high-cost torque motor on the original wire take-up vehicle. Also, because the take-up torque range of the torque motor is very small, usually 1-3 N is one gear for one motor, the torque range of this set of dampers can be adjusted to more than 1-50 N or even higher, and the efficiency and function are completely improved.
[0037] A snap ring 16 is installed on the outer circumferential wall of the rotating disk 12;
[0038] By providing the snap ring 16, the position between the rotating disk 12 and the fixed disk 5 can be limited to prevent the rotating disk 12 from axially displacing relative to the wire take-up spool 1.
[0039] A limit set screw 10 is fixed to the outer wall of one side of the rotating disk 12 by a pin, and a limit groove 9 of the wire reel 3 adapted to the outer diameter of the limit set screw 10 is formed in the side wall of the wire reel 3;
[0040] By providing the limit set screw 10, the position between the rotating disk 12 and the wire reel 3 can be limited to prevent the wire reel 3 from rotating relative to the rotating disk 12.
[0041] In the use of this embodiment, first, the wire reel 3 is sleeved on the circumferential outer wall of the take-up shaft 1, and it is ensured that one outer wall of the wire reel 3 abuts against the support member. Then, by rotating the setscrew 4, it is threadedly connected to the inner wall of the threaded hole formed on the circumferential outer wall of the fixed disk 5. As the setscrew 4 rotates continuously, one end of it finally abuts tightly against the circumferential outer wall of the take-up shaft 1, thereby completing the fixed connection between the take-up shaft 1 and the fixed disk 5. To further fix the wire reel 3, the pressing disk 8 in the sliding and pressing assembly moves along the take-up shaft 1 until it abuts against the other end of the wire reel 3. Then, a clamp is installed at the end of the spring 6 away from the support bearing 7, and the spring 6 is squeezed to gradually compress it. A certain pressure is maintained between the pressing disk 8 and the wire reel 3, thereby enhancing the stability of the wire reel 3 during wire winding and unwinding. The damping adjustment mechanism mainly consists of an Allen screw 11, a first spring 17, and a nylon column 18. These components are all slidably connected to the inner wall of the threaded hole formed on the circumferential outer wall of the friction disk 2, and the Allen screw 11 is threadedly connected to the threaded hole. When it is necessary to adjust the damping, the Allen screw 11 is rotated. During the rotation process, the Allen screw 11 applies pressure to the first spring 17, and through the transmissibility of force, the nylon column 18 applies damping to the circumferential outer wall of the rotating disk 12. The magnitude of the damping can be controlled by adjusting the rotation degree of the Allen screw 11. In this way, no matter how thick or thin the metal wire is wound on the wire reel 3, the appropriate take-up torque can be maintained by adjusting the damping, thereby ensuring that the physical properties of the metal wire are not damaged. During the wire winding and unwinding process, the wire reel 3 will rotate as the metal wire is wound and unwound. Since the rotating disk 12 is rotatably connected to the take-up shaft 1 through a first bearing 14 and a second bearing 15, the rotating disk 12 can rotate freely relative to the take-up shaft 1. At the same time, by setting the limit setscrew 10 and the limit groove 9 of the wire reel 3, relative rotation of the wire reel 3 relative to the rotating disk 12 can be avoided, and the wire reel 3 can remain stable during the wire winding and unwinding process. When the metal wire is wound on the wire reel 3, due to the damping effect, the rotation of the rotating disk 12 will be subject to a certain resistance, and this resistance can be controlled by adjusting the damping adjustment mechanism, thereby achieving precise adjustment of the take-up torque.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
