Description

Technical Field

[0001] This application relates to the field of cable manufacturing, and more particularly to an unwinding device and cable manufacturing equipment. Background Technology

[0002] In cable production, the pay-off device is a critical piece of equipment, and its performance directly affects cable quality and production efficiency. Traditional pay-off devices typically use stepper motors to control the pay-off speed. While this achieves a certain degree of precision control, it also has significant drawbacks, including high cost, easy loosening of the pay-off wire, complex maintenance, and high energy consumption. Specifically, stepper motors themselves are expensive and require corresponding drivers and control systems, further increasing equipment costs. Simultaneously, stepper motors are prone to vibration at low speeds, leading to unstable pay-off tension and potential cable loosening, affecting product quality. Furthermore, the complex structure of stepper motors and their control systems requires professional maintenance, increasing maintenance and time costs. The high energy consumption of stepper motors during operation is also detrimental to energy conservation and emission reduction. Existing solutions using servo motors and magnetic powder clutches address these issues; however, these solutions still suffer from high costs and complex control, failing to meet the actual needs of cable manufacturers.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] Currently, when unwinding wire, a motor is usually used to drive the spool to rotate or to provide damping force to prevent the wire from loosening. However, using a motor is costly and difficult to control.

[0042] This application provides an unwinding device to solve the above problems. The unwinding device provided in the embodiments of this application includes a base 100, a rotating shaft 200, a clamp 300, an elastic band 400, and a coil 500.

[0043] In some embodiments, the rotating shaft 200 is rotatably mounted on the base 100, the clamp 300 is disposed on the rotating shaft 200, one end of the elastic band 400 is connected to the clamp 300, and the other end of the elastic band 400 away from the clamp 300 is connected to the base 100. The spool 500 is disposed on the rotating shaft 200 and rotates with the rotating shaft 200.

[0044] See Figure 1 and Figure 2 As shown, when the reel 500 rotates together with the shaft 200, a certain amount of resistance needs to be applied to the reel 500 to prevent the unwound cable from becoming loose. For this purpose, a clamp 300 is fitted onto the outer surface of the shaft 200, and then the clamp 300 is tied to the outer surface of the shaft 200 by an elastic band 400. It can be understood that the stretching of the clamp 300 by the elastic band 400 makes the clamp 300 fully contact the outer surface of the shaft 200, and under the action of the stretching force of the elastic band 400, a certain amount of friction is generated between the clamp 300 and the shaft 200. This friction prevents the shaft 200 from rotating. Since the reel 500 rotates together with the shaft 200, a damping force can also be applied to the reel 500 to prevent the unwound cable from becoming loose.

[0045] It is understandable that this application uses the elastic belt 400 as the damping power for the rotation of the coil 500, thus eliminating the need for a motor to provide resistance. Compared with a motor, the elastic belt 400 is inexpensive and does not require a large cost.

[0046] In this embodiment, the elastic band 400 will deform under force, which will pull the clamp 300 to stick tightly to the outer surface of the rotating shaft 200 to generate friction, thus providing resistance to the rotation of the rotating shaft 200 and the coil 500.

[0047] It should be noted that in this embodiment, the rotating shaft 200 is vertically mounted on the base 100.

[0048] The base 100 includes a bracket 110, a first mounting plate 120, and a second mounting plate 130. The first mounting plate 120 is fixedly mounted on the top of the bracket 110, and the rotating shaft 200 is rotatably connected to the first mounting plate 120. The second mounting plate 130 is fixedly disposed at the bottom of the bracket 110, and the rotating shaft 200 is rotatably connected to the second mounting plate 130. The clamp 300 is located between the first mounting plate 120 and the second mounting plate 130.

[0049] Please see Figure 1 and Figure 2As shown, in order to prevent the rotating shaft 200 from tilting under force, in this embodiment of the application, the rotating shaft 200 is rotatably connected to the first mounting plate 120 and the second mounting plate 130, and there is a certain distance between the first mounting plate 120 and the second mounting plate 130, so that the rotating shaft 200 can rotate more stably and prevent cleaning. It can be understood that the rotating shaft 200 can be rotated with the first mounting plate 120 and the second mounting plate 130 using bearings. Specifically, angular contact ball bearings can be used, which can withstand both radial force and a certain axial force, thus meeting the needs of this application.

[0050] A rotating cylinder 600 is fixedly mounted on the rotating shaft 200. The rotating cylinder 600 is located between the first mounting plate 120 and the second mounting plate 130. The clamp 300 is disposed on the outer surface of the rotating cylinder 600.

[0051] Please see Figure 1 , Figure 2 as well as Figure 7 As shown, in order to provide sufficient resistance, a rotating drum 600 is provided on the outer surface of the rotating shaft 200 between the first mounting plate 120 and the second mounting plate 130. It can be understood that the diameter of the rotating drum 600 is larger than the diameter of the rotating shaft 200, that is, the outer surface area of ​​the rotating drum 600 is larger, and the contact area with the clamp 300 is also larger. Therefore, the contact area is increased to increase the friction between the clamp 300 and the rotating drum 600, increase the movement resistance of the rotating shaft 200 and the clamp 300, and prevent the cable unwound by the reel 500 from becoming loose.

[0052] The clamp 300 includes an annular piece 310, and a connecting piece 320 is provided at both ends of the annular piece 310. The connecting piece 320 has a connecting hole 321, and the elastic band 400 passes through the connecting hole 321 and connects to the connecting piece 320.

[0053] See Figure 3 As shown, the annular plate 310 is an annular plate, and the arc shape of the annular plate 310 is adapted to the rotating cylinder 600 so that the inner wall of the annular plate 310 can fully fit with the outer surface of the rotating cylinder 600. In order to generate friction between the rotating cylinder 600 and the inner wall of the annular plate 310 to provide rotational resistance to the rotating cylinder 600 and the rotating shaft 200, connecting plates 320 are integrally provided at both ends of the annular plate 310. Each connecting plate 320 has a connecting hole 321. The connecting hole 321 is mainly used for the elastic band 400 to be tied and connected to the connecting plate 320, thereby pulling the connecting plate 320 to move away from the axis of the rotating cylinder 600, so that the inner wall of the annular plate 310 and the outer surface of the rotating cylinder 600 always remain in contact, providing a motion resistance to the rotating shaft 200 and the coil 500.

[0054] It should be noted that, in order to improve the overall service life, the material of the annular plate 310 should preferably be a wear-resistant material, such as stainless steel or cemented carbide. The specific type of wear-resistant material is not limited here.

[0055] A connector 700 is fixedly installed on the base 100, and one end of the elastic band 400 away from the clamp 300 is connected to the connector 700.

[0056] Please continue reading. Figure 1 , Figure 2 as well as Figure 7 As shown, in order to fix the other end of the elastic band 400 to the base 100, a connector 700 is installed on the base 100. The connection between the elastic band 400 and the base 100 can be achieved simply by binding the end of the elastic band 400 away from the clamp 300 to the connector 700.

[0057] Understandably, if it is necessary to adjust the friction between the clamp 300 and the rotating drum 600, it is only necessary to adjust the extension length of the elastic band 400. Furthermore, the elastic band 400 can be replaced by a spring, that is, any component that can achieve extension and retraction can be used.

[0058] The coil 500 includes a central tube 510, which has a central hole 511 at its center. Side plates 520 are provided at both ends of the central tube 510, forming an accommodating space 530 between the side plates 520 and the central tube 510. The accommodating space 530 is used for winding the cable.

[0059] Please see Figure 2 As shown, in order for the coil 500 to unwind the cable, a center hole 511 is provided at the center of the center hole 511. The diameter of the center hole 511 should be larger than the diameter of the shaft 200 so that it can be fitted onto the outer surface of the shaft 200. Specifically, side plates 520 are provided at both ends of the center tube 510. The side plates 520 block the cable wound on the outer surface of the center tube 510, thereby enabling more cable to be unwound. It can be understood that the accommodating space 530 formed by the center tube 510 and the two side plates 520 is the cable winding space.

[0060] Both ends of the coil 500 are provided with positioning members 800. The positioning member 800 includes a base plate 810. A tapered member 820 is provided on one side of the base plate 810. The tapered member 820 is partially located in the central hole 511. The center of the base plate 810 and the tapered member 820 are provided with a sleeve hole 821. The circumferential surface of the base plate 810 is provided with a plurality of mounting holes 811. The mounting holes 811 communicate with the sleeve holes 821. A screwing member 830 that can extend into the sleeve hole 821 is installed in the mounting hole 811.

[0061] Please see Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, in order to ensure that the coil 500 and the rotating shaft 200 are located on the same central axis, positioning elements 800 are provided at both ends of the coil 500. The positioning elements 800 position the center of the coil 500 so that the coil 500 does not deflect when rotating. The positioning elements 800 are fixedly installed on the rotating shaft 200 and abut against the coil 500. Through the force transmission of the positioning elements 800, the rotating shaft 200 and the coil 500 can rotate synchronously.

[0062] Specifically, the screw is first fitted onto the rotating shaft 200 through the fitting hole 821, and then the screwing member 830 is rotated so that its end abuts against the outer surface of the rotating shaft 200, thereby achieving the center positioning of the base plate 810 and the conical member 820. Furthermore, in this embodiment, there are four screwing members 830, which are evenly spaced about the central axis of the base plate 810. The four screwing members 830 achieve the center positioning of the base plate 810 and fix the base plate 810 and the conical member 820 to the rotating shaft 200 for connection. It can be understood that the screwing member 830 is a bolt and the mounting hole 811 is a threaded hole.

[0063] Please continue reading. Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, a positioning component 800 is first installed at the bottom of the rotating shaft 200. The base plate 810 is then installed on the rotating shaft 200 by the ends of each screwing component 830 abutting against the outer surface of the rotating shaft 200. At this time, the axes of the base plate 810 and the tapered component 820 are on the same axis as the axis of the rotating shaft 200. Figure 2 As shown, the coil 500 is then mounted on the rotating shaft 200, at which point the tapered part 820 extends into the central hole 511, and the central tube 510 is centered by the tapered part 820; similarly, the tapered part 820 of the positioning part 800 at the top of the rotating shaft 200 also extends into the central hole 511, and the top of the central tube 510 is also centered.

[0064] To enable the spool 500 to rotate synchronously with the shaft 200, multiple grooves 840 are provided on the circumferential surface of the tapered member 820 to participate in... Figure 4 and Figure 6 As shown, the central tube 510 is inserted into the central hole 511 through the groove 840. Under the action of gravity, the central tube 510 is in close contact with the outer surface of the conical part 820, which improves the force transmission between the conical part 820 and the central tube 510, so that the coil 500 can rotate together with the positioning part 800 and the rotating shaft 200.

[0065] The maximum diameter of the tapered component 820 is D, and the diameter of the central hole 511 is d, satisfying the condition: D > d.

[0066] Please see Figure 2 As shown, in order to achieve synchronous rotation between the shaft 200 and the coil 500, the maximum diameter of the tapered part 820 should be greater than the diameter of the central hole 511, and the minimum diameter of the tapered part 820 should be smaller than the diameter of the central hole 511. This allows the tapered part 820 to partially penetrate into the central hole 511. Furthermore, since the coil 500 is placed vertically, under the action of gravity, the inner wall end of the central tube 510 will be tightly attached to the outer wall of the tapered part 820, thereby improving the transmission of force and enabling the coil 500 to rotate synchronously with the shaft 200.
