Description

Technical Field

[0001] This utility model relates to the technical field of cable winding, and in particular to a cable winding device with automatic tension adjustment. Background Technology

[0002] In the production of wires and cables, cable winding equipment is an indispensable tool. From the initial processing of raw materials to the packaging of finished cables, cable winding is essential. During the drawing stage of metal wires such as copper and aluminum wires, the wires, after being stretched by the drawing machine, need to be wound onto spools for further processing, such as stranding and insulation coating. In the finished cable stage, according to different customer needs, the cables are wound into spools of different lengths and specifications for convenient transportation and sales.

[0003] Patent "CN202221420921.X" proposes a workbench, a winding mechanism, an adjustment mechanism, and an unwinding mechanism. The workbench provides a working environment for the winding, adjustment, and unwinding mechanisms. The winding mechanism is mounted on the top surface of one end of the workbench along its length, and the unwinding mechanism is mounted on the top surface of the other end. The adjustment mechanism is located between the winding and unwinding mechanisms to adjust the winding position of the cable. However, the tension of the cable in this patent cannot be adjusted. When the cable tension is too high during winding, it may cause the cable to be stretched and deformed. If the tension is too low, the cable is prone to loosening and tangling during winding. When the cable is crisscrossed or unevenly stacked on the winding device, the outer sheath may be worn due to friction between the cables or its own compression during subsequent unwinding, thus affecting the insulation performance and service life of the cable. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tension-adjusting cable winding device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mounting frame for a cable winding device, a winding roller is mounted in the middle of the mounting frame, a guide rail is mounted at the upper end of the mounting frame, a cable laying device is mounted in the middle of the guide rail, and an adjustment device for controlling tension is mounted on one side of the mounting base in the cable laying device.

[0006] The adjusting device includes a rotating rod with threaded sections at both ends. A threaded seat is threadedly connected to the rotating rod at the position of the threaded section. The threaded seat is slidably connected to the mounting base. A return spring is fixedly installed at one end of the threaded seat near the middle position. A clamping block is fixedly installed at the end of the return spring away from the threaded seat. One end of the rotating rod is connected to the motor output shaft. The clamping block is slidably connected to the mounting base.

[0007] One of the return springs is longer than the other return spring;

[0008] The longer return spring has a smaller spring force than the shorter return spring.

[0009] In practical applications, when the cable tension is too low during winding and needs to be increased, the motor output shaft drives the rotating rod to rotate. The rotating rod causes the two threaded seats to move closer together. Since one of the return springs is longer than the other, the longer return spring will cause one of the clamping blocks to press against the outer wall of the turntable. Through the friction between the clamping block and the turntable, the rotation speed of the turntable is changed. When the rotation speed of the turntable slows down, the speed of the roller also slows down. Through the speed difference between the roller and the winding roller, the cable tension is changed, effectively preventing the cable from becoming loose during winding. Since one of the return springs is longer than the other, after the motor output shaft continues to drive the rotating rod to rotate, the other clamping block will contact the turntable, thereby further changing the cable tension.

[0010] Furthermore, the cable laying device includes a mounting base that mates with the guide rail. Two rotating shafts are rotatably mounted inside the mounting base. A roller is fixedly mounted in the middle of each rotating shaft, and a turntable is fixedly mounted at one end of each rotating shaft. The outer wall of the roller is provided with anti-slip rubber. In practical applications, one of the rotating shafts is a lead screw, which is connected to the output shaft of a drive motor. When the cable laying device needs to move left or right, the output shaft of the drive motor drives the lead screw to rotate, which in turn moves the mounting base. The mounting base then moves the cable left or right, thereby evenly distributing the cable on the surface of the take-up roller.

[0011] Furthermore, each end of the clamping block is fixedly provided with an arc-shaped rod that cooperates with the outer wall of the turntable.

[0012] Furthermore, a guide block is fixedly installed inside the mounting base, and an arc-shaped guide surface is provided on one side of the guide block;

[0013] In practical applications, when it is necessary to thread a cable, the cable will slide along the arc surface of the guide block to the position between the two rollers as it passes the guide block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device changes the cable tension by varying the speed of the rollers and the take-up rollers, effectively preventing the cable from becoming loose during take-up. Because one of the two return springs is longer than the other, when the motor output shaft continuously drives the rotating rod to rotate, the other clamping block will contact the turntable, thereby further changing the cable tension.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Reference Figure 1-4 An automatic tension-adjusting cable winding device includes a cable winding device mounting frame 1, a winding roller 2 mounted in the middle of the mounting frame 1, a guide rail 3 mounted on the upper end of the mounting frame 1, a cable laying device 4 mounted in the middle of the guide rail 3, and a tension-adjusting device 5 mounted on one side of the mounting base 401 in the cable laying device 4.

[0024] The adjusting device 5 includes a rotating rod 501, with threaded sections at both ends of the rotating rod 501. A threaded seat 504 is threadedly connected to the rotating rod 501 at the position of the threaded section. The threaded seat 504 is slidably connected to the mounting base 401. A return spring 503 is fixedly installed at one end of the threaded seat 504 near the middle position. A clamping block 502 is fixedly installed at the other end of the return spring 503 away from the threaded seat 504. One end of the rotating rod 501 is connected to the motor output shaft. The clamping block 502 is slidably connected to the mounting base 401.

[0025] One of the return springs 503 is longer than the other return spring 503;

[0026] The longer return spring 503 has a smaller spring force than the shorter return spring 503.

[0027] In practical applications, when the cable tension is too low during winding and needs to be increased, the motor output shaft drives the rotating rod 501 to rotate. The rotating rod 501 drives the two threaded seats to move closer together. Since one of the two return springs 503 is longer than the other, the longer return spring 503 will cause one of the clamping blocks 502 to press against the outer wall of the turntable 6. Through the friction between the clamping block 502 and the turntable 6, the rotation speed of the turntable 6 is changed. When the rotation speed of the turntable 6 slows down, the speed of the roller 402 also slows down. Through the speed difference between the roller 402 and the winding roller 2, the cable tension is changed, effectively preventing the cable from becoming loose during winding. Since one of the two return springs 503 is longer than the other, after the motor output shaft continues to drive the rotating rod 501 to rotate, the other clamping block 502 will contact the turntable 6, thereby further changing the cable tension.

[0028] Furthermore, the cable laying device 4 includes a mounting base 401 that works in conjunction with the guide rail 3. Two rotating shafts 403 are rotatably mounted inside the mounting base 401. A roller 402 is fixedly mounted in the middle of the rotating shaft 403, and a turntable 6 is fixedly mounted at one end of the rotating shaft 403. The outer wall of the roller 402 is provided with anti-slip rubber. In practical applications, one of the rotating shafts 403 is a lead screw, which is connected to the output shaft of the drive motor. When the cable laying device 4 needs to move left or right, the output shaft of the drive motor drives the lead screw to rotate, the lead screw drives the mounting base 401 to move, and the mounting base 401 drives the cable to move left or right, so that the cable is evenly distributed on the surface of the take-up roller 2.

[0029] Furthermore, the clamping block 502 is fixedly provided with arc-shaped rods at both ends to cooperate with the outer wall of the turntable 6.

[0030] Furthermore, a guide block 404 is fixedly installed inside the mounting base 401, and an arc-shaped guide surface is provided on one side of the guide block 404;

[0031] In practical applications, when it is necessary to thread a cable, the cable will slide along the arc surface of the guide block 404 to the position between the two rollers 402 when it passes the guide block 404.

[0032] Working principle: When the cable tension is too low during winding and needs to be increased, the motor output shaft drives the rotating rod 501 to rotate. The rotating rod 501 drives the two threaded seats to move closer together. Since one of the two return springs 503 is longer than the other, the longer return spring 503 will drive one of the clamping blocks 502 to press against the outer wall of the turntable 6. Through the friction between the clamping block 502 and the turntable 6, the rotation speed of the turntable 6 is changed. When the rotation speed of the turntable 6 slows down, the speed of the roller 402 will also slow down. Through the speed difference between the roller 402 and the winding roller 2, the cable tension is changed, effectively preventing the cable from becoming loose during winding. Since one of the two return springs 503 is longer than the other, after the motor output shaft continues to drive the rotating rod 501 to rotate, the other clamping block 502 will contact the turntable 6, thereby further changing the cable tension.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
