Description

Technical Field

[0001] The utility model relates to the technical field of cable covering equipment, in particular to a longitudinal covering device for a cable inner lining layer. Background Art

[0002] Cable coating processes include extrusion, longitudinal wrapping, wrapping, and dipping, each of which has its own specific application scenarios and material utilization efficiency. Longitudinal wrapping and wrapping are two common coating methods, and they have obvious differences in material utilization efficiency. In the longitudinal wrapping process, the material is continuously covered on the cable to form one or more layers of coverage. This method is relatively material-saving because it can fit the shape of the cable more closely and reduce material waste. In contrast, in the wrapping process, the material is wrapped on the cable in the form of a coil. This method is relatively less economical in terms of material use because it requires more material to ensure complete coverage of the cable, and there is also additional material consumption in the splicing and processing of the material.

[0003] The existing cable inner lining longitudinal wrapping production process and longitudinal wrapping equipment have the following defects: In terms of production process, 1. The longitudinal wrapping accuracy is difficult to guarantee: the longitudinal wrapping process requires high wrapping accuracy for the cushion layer, but the existing process may cause wrinkles, unevenness and other problems in the cushion layer after longitudinal wrapping due to factors such as equipment accuracy and operating techniques. These uneven areas may affect the appearance quality of the cable, and when the cable is bent or subjected to external force, stress concentration is likely to occur at the wrinkles, accelerating the damage of the cable. 2. Low production efficiency: The process of some longitudinal wrapping production processes is relatively complicated, and the operating steps are cumbersome, requiring a lot of time and manpower, resulting in low production efficiency. For example, some traditional longitudinal wrapping equipment requires manual operations such as material loading and positioning, which is not only labor-intensive, but also prone to human errors, affecting product quality.

[0004] This case was created to solve the above problems. Utility Model Content

[0025] The present invention will be further described in detail below through the accompanying drawings and examples.

[0026] like Figure 1-5 As shown: A longitudinal wrapping device for a cable inner lining layer includes a base 1. Since the wrapping belt 3 will have a large pulling force when it is pulled under tension, the base 1 should be set with a large weight to prevent the entire frame from shaking or even tipping over along the forward direction of the cable.

[0027] Base 1 is equipped with multiple support rods 14, which are arranged circumferentially around cable core 2 to support trays 5. Each tray 5 is adjustable in angle (i.e., horizontal or vertical movement, achieved by adjusting the length of the support rods 14 connecting the trays 5). This allows the wrapping tape 3 to increase the coverage when wrapping the cable longitudinally. Depending on the cable outer diameter and the specifications of the wrapping tape 3, four, three, or two tapes can be used. Adjusting the angle of the trays 5 adjusts the coverage. Note: The trays 5 do not rotate with the bearings 6.

[0028] Bearing 6 is mounted on the tray 5. Bearing 6 is the central axis for the rotational output of the tape reel 7. The size of the tape reel 7 may leave a gap between the bearing 6 and the tape reel 7. Anti-slip cones 17 can be arranged on the outer wall of the bearing 6. When there is a gap between the tape reel 7 and the bearing 6, the anti-slip cones 17 support the tape reel 7, allowing the tape reel 7 and the bearing 6 to rotate synchronously. Secondly, an anti-slip lock can be provided on the tape reel 7 on the bearing 6 to prevent the tape 3 or the tape reel 7 from detaching from the shaft during rotation.

[0029] See attached Figure 2 As shown, a tension rod 12 is provided at the wrapping tape 3. The tension rod 12 should be circular, and the outer diameter should not be too small to easily tear the wrapping tape 3. A tension rod 12 is provided at each wrapping tape 3. Specifically, a connecting rod 9 is provided on the side of the support rod 14-42. The upper distal end of the connecting rod 9 is connected to a bracket 10. A limit rod 11 is connected to the outer extension of the bracket 10 and is in contact with the wrapping tape 3. The tension rod 12 is in contact with the other side of the wrapping tape 3, and the tension rod 12 can be relatively moved and adjusted to keep the wrapping tape 3 tight, avoiding wrinkles when it is in contact with the cable core 2.

[0030] One end of the tension rod 12 is connected to a guide seat, which is connected to the bracket 10 via a return spring 13. The return spring 13 squeezes the strap 3 inward, making the strap 3 relatively tight after passing through the tension rod 12. At the same time, a pull rod 16 is connected to the guide seat. The other end of the pull rod 16 passes through the guide seat, and a limit screw sleeve 15 is provided at the junction with the guide seat. The outer end of the pull rod 16 is threaded and threadedly connected to the limit screw sleeve 15, so that it can support the tension rod 12 and adjust the initial state of the tension rod 12 by pre-adjusting the length of the screw connection of the pull rod 16.

[0031] See attached Figure 1 、 3 As shown, the horizontal support rod 14 is located at the outlet of the cable core 2 and is equipped with multiple combinations of belt rings 8. Each combination of belt rings 8 is provided with one or more belt rings 8 from small to large. To ensure a more comfortable wrapping of the belt 3, two or more groups can be provided (this solution shows two groups). The inner ring size of the belt ring 8 can be adjusted through assembly. When wrapping a large core cable longitudinally, the large belt ring 8 is used, and the small belt ring 8 is removed. When wrapping a small core cable longitudinally, the small belt ring 8 is used, and the small belt ring 8 can be assembled into the large belt ring 8.

[0032] Specifically, a card slot 83 is provided on the inner surface of the belt ring 8, and a card block 82 is connected to the outer surface, so that the connection can be clamped, and the card slot 83 is provided on the front side of the conduction direction of the cable core 2, so that the force is in the reverse direction and the small belt ring 8 will not be separated from the large belt ring 8. At the same time, a push rod 84 is connected to the back side of each belt ring 8 to facilitate pushing out and disassembly.

[0033] Generally, there is a certain gap between the cable core 2 and the closing ring 8. In order to make the tape 3 stick to the surface of the cable when wrapping, the inner ring of the closing ring 8 is provided with a rubber ring layer with a certain elasticity, which can squeeze the buffer tape 3 to a certain extent, preventing it from shaking and shifting while fitting the cable core 2.

[0034] Because the cable core 2 is long, the front side can be directly supported by the belt ring 8, and the rear side can be movably supported by the support assembly 4. The support assembly 4 includes a support plate 41, to which are connected a relatively retractable rod 1 42 and a second rod 43, which are fixed by bolts. The height is adjusted by the different widths of the cable core 2. The upper end of the second rod 43 is connected to a support block 44, and a guide wheel 45 is pivotally connected to the support block 44. The guide wheel 45 is formed by two conical wheels with a larger outer side and a smaller inner side. The cable core 2 is placed in the guide wheel 45 for rotational support and smooth transmission.

[0035] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
