Description

TECHNICAL FIELD

[0001] The utility model belongs to cable unwinding device technical field, concretely relates to a cable unwinding device for wrapping machine. BACKGROUND

[0002] The cable unwinding device is the core supporting component of the wrapping machine, is mainly used for stably conveying the cable roll material to the wrapping station, and directly influences the efficiency, precision and product quality of the wrapping process. At present, the device is widely applied to the insulating layer wrapping, shielding layer wrapping process in the fields of wire and cable, communication cable, new energy cable and the like. With the development of the cable industry to "thinness, multi-specification and high precision", the existing cable unwinding device for wrapping machine gradually exposes many technical pain points, and it is difficult to meet the industry upgrading demand.

[0003] The current cable production presents the characteristics of "multi-variety and small batch", and the same production line needs to frequently switch the cable roll materials of different diameters (such as 20mm-300mm) and different lengths (such as 300mm-1500mm). However, the unwinding roller clamp of the existing unwinding device is designed in a fixed specification, when replacing the cable roll materials of different specifications, the original clamp needs to be disassembled and replaced with the adaptive model, which not only consumes time (30-60 minutes for single replacement), but also needs to reserve multiple specifications of clamps, thereby increasing the equipment procurement and inventory costs. In addition, although part of the devices support small-scale adjustment, the adjustment range is limited (such as the diameter adaptive range is only 50mm-100mm), and cannot cover the mainstream cable specifications in the industry, so the universality is very poor.

[0004] The utility model aims at solving the above problems and provides a cable unwinding device for wrapping machine which is simple in structure and reasonable in design.

[0005] The utility model achieves the above-mentioned purposes through the following technical solutions:

[0013] The beneficial effects of this utility model are as follows:

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1: As Figure 1 - Figure 3As shown, a cable unwinding device for a wrapping machine includes an adjusting base 1, a first adjusting component 2, a drive motor adjusting component 3, a displacement adjusting component 4, a cable unwinding roller 5, and various matching connecting parts; wherein, the drive motor adjusting component 3 includes a movable base 301, a lifting slider 302, a first lead screw 303, a limiting light rod 304, a first servo motor 305, a second servo motor 306, an unwinding roller connecting part 307, and a displacement slide 308; the displacement adjusting component 4 includes a limiting slide 401, a second lead screw 402, a third servo motor 306, and a second servo motor 407. The machine 403 and the adjusting slide 404 are included. The first adjusting component 2 includes a sliding plate 201, a cylinder 202, a first limiting slide 203, and a slide bar 204. First, the basic assembly of the adjusting base 1 is carried out: the side plate 101 is fixedly installed on the front side wall of the adjusting base 1 to ensure that the side plate 101 is perpendicular to the adjusting base 1 and is firmly fixed; then, the two limiting slides 401 of the displacement adjusting component 4 are symmetrically fixed on the inner side wall of the adjusting base 1. The distance between the two limiting slides 401 is adapted to the length of the cable unwinding roller 5 to provide a guiding foundation for the subsequent sliding components.

[0023] like Figure 1 - Figure 4 As shown, a second lead screw 402 is rotatably connected to the inner wall of the adjusting base 1 between the two limiting slides 401 via bearings. A third servo motor 403 is fixedly installed on the side wall of the adjusting base 1. The output end of the third servo motor 403 is fixedly connected to one end of the second lead screw 402 to ensure that the motor can drive the second lead screw 402 to rotate synchronously after starting. Two adjusting slides 404 are slidably sleeved on the outer wall of the second lead screw 402. The two adjusting slides 404 can be manually driven to slide relative to or towards each other. At the same time, on the outer wall of the two limiting slides 401... A sliding displacement slide 308 is mounted together. The displacement slide 308 is located on one side of the cable unwinding roller 5, and its inner wall is threaded to the second lead screw 402 to realize horizontal displacement adjustment driven by the third servo motor 403. The cable unwinding roller 5 is placed on top of the two adjusting slides 404. The bottom ends of the cable unwinding roller 5 are clamped by the relative sliding of the adjusting slides 404 to realize the adaptation support for cable unwinding rollers of different diameters. One end of the cable unwinding roller 5 is locked and fixed to the unwinding roller connector 307 of the drive motor adjusting assembly 3 to ensure stable power transmission.

[0024] like Figure 1 - Figure 3As shown, two first limiting slide blocks 203 are fixedly installed on the top of the displacement slide table 308. Slide bars 204 are slidably connected to the bottom of each of the two first limiting slide blocks 203. The two slide bars 204 are fixed to the bottom sides of the movable base 301, so that the movable base 301 is slidably connected to the top of the displacement slide table 308 through the cooperation of the slide bars 204 and the first limiting slide blocks 203. A first lead screw 303 is rotatably connected to the inner wall of the movable base 301 via a bearing. A lifting slider 302 is threaded onto the outer wall of the first lead screw 303. Simultaneously, four limiting rods 304 are fixedly installed at the four corners of the inner wall of the movable base 301. The lifting slider 302 is slidably fitted onto the outer walls of the four limiting rods 304, achieving stable guidance of the lifting slider 302. A first limiting rod 304 is fixedly installed on the top of the movable base 301. A first servo motor 305 is installed, and its output end is fixedly connected to the top of the first lead screw 303 to form a lifting drive mechanism. Finally, the mounting end of the second servo motor 306 is fixed to the side wall of the lifting slider 302, and the output end of the second servo motor 306 is fixedly connected to one end of the unwinding roller connector 307 to realize the rotation drive and height adjustment of the cable unwinding roller 5. A sliding plate 201 is slidably connected to the top of the side plate 101. Specifically, a groove is opened on the top of the side plate 101 to cooperate with the sliding plate 201. A cylinder 202 is fixedly installed on the top of the sliding plate 201, and the output end of the cylinder 202 is fixedly connected to the front side wall of the movable base 301. The movable base 301 is driven to slide laterally along the first limit slide 203 by the extension and retraction of the cylinder 202, and multi-dimensional position adjustment is realized in conjunction with the displacement slide 308.

[0025] It should be noted that, in use, the cable unwinding device for this type of wrapping machine allows for manual adjustment of the position between the two adjusting slides 404 according to the width of the unwinding roller, ensuring a proper fit. After the unwinding roller 5 is pushed onto the two adjusting slides 404, the third servo motor 403 drives the displacement slide 308 to move horizontally along the limiting slide 401, initially calibrating the position of the unwinding roller. The cylinder 202 pushes the movable base 301 for fine-tuning laterally along the first limiting slide 203, ensuring precise engagement between the unwinding roller connector 307 and the unwinding roller. During the adaptation phase, the first servo motor 305 drives the first lead screw 303 to rotate, causing the lifting slider 302 to rise and fall smoothly along the limit rod 304. The height of the second servo motor 306 is adjusted to ensure that the unwinding roller rotates horizontally. During unwinding, the second servo motor 306 drives the cable unwinding roller 5 to rotate at a uniform speed through the unwinding roller connector 307, outputting the cable to the wrapping machine. If the unwinding position needs to be adjusted, it can be finely adjusted by the third servo motor 403 or the cylinder 202. All components work together throughout the process to achieve precise control of the unwinding position, height, and speed, ensuring stable cable delivery.

[0026] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
