Description

Technical Field

[0001] This utility model relates to a longitudinal wrapping mold, and more particularly to a longitudinal wrapping mold for high-frequency cables. Background Technology

[0002] Driven by big data and artificial intelligence technologies, hardware manufacturers are facing unprecedented challenges from internet service providers and network providers, particularly in delivering high-speed, high-bandwidth hardware. With the introduction of 56G and 112G high-speed chipsets, traditional PCB solutions are gradually reaching their performance limits, urgently requiring innovative technologies and solutions. Currently, a solution is to replace the PCB backplane with high-frequency signal lines to address this issue. However, because high-frequency signal lines are highly susceptible to electromagnetic interference, aluminum or copper foil needs to be longitudinally wrapped around the core wire during the high-frequency cable wrapping process to ensure stable transmission of high-frequency signals.

[0003] In the longitudinal wrapping process of frequency cables, aluminum foil, as part of the shielding layer, is usually used to wrap the conductor inside the cable to provide electromagnetic interference (EMI) protection. However, the existing longitudinal wrapping molds are fixed and do not have a flattening function. When the aluminum foil wrinkles, it usually needs to be adjusted manually. However, the aluminum foil is thin and manual adjustment can easily lead to the aluminum foil breaking, which may result in discontinuity of the shielding layer and reduce its ability to protect against electromagnetic interference.

[0004] To prevent wrinkles from forming on the aluminum foil during the longitudinal wrapping process of high-frequency cables, it is urgent to design a longitudinal wrapping mold with a flattening function for high-frequency cables. Utility Model Content

[0005] To overcome the shortcomings of current longitudinal wrapping molds, which use fixed settings and lack flattening capabilities, and which typically require manual adjustment when aluminum foil wrinkles, leading to foil breakage, this invention provides a high-frequency cable longitudinal wrapping mold with a flattening function.

[0006] The technical solution is as follows: A high-frequency cable longitudinal wrapping mold includes a base, a slide rail, mold block D, mold block C, mold block B, mold block A, a fixing frame, a support plate, guide rods, scrapers, and tension springs. A slide rail is provided on one side of the top of the base. Mold blocks D, C, B, and A are slidably arranged on the slide rail from front to back. A fixing frame is provided at the end of the base away from the slide rail. A support plate is installed on one side of the fixing frame. Guide rods are symmetrically arranged on the support plate. Scrapers are slidably arranged on the symmetrical guide rods. Tension springs are wound on the guide rods.

[0007] As a further preferred embodiment, it also includes a pressure roller, a spring, and an electric roller. The electric roller is rotatably arranged on one side of the fixed frame, and the pressure roller is slidably and rotatably arranged on the other side of the fixed frame. The spring is symmetrically arranged between the pressure roller and the fixed frame.

[0008] As a further preferred embodiment, it also includes push rods and cams, with cams symmetrically arranged on both sides of the pressure roller and push rods symmetrically arranged on both sides of the scraper, with the end of the symmetrical push rod away from the scraper slidingly against the surface of the cam.

[0009] As a further preferred embodiment, it also includes a fixing frame and a cleaning brush, wherein the fixing frame is provided on the side of the fixing frame away from the support plate, and the cleaning brush is symmetrically arranged inside the fixing frame.

[0010] As a further preferred option, a heating pad is also included, with a heating pad provided at the bottom of the support plate.

[0011] As a further preferred embodiment, it also includes a partition plate and conveying pipes, with a partition plate installed at the top of the fixed frame and several conveying pipes installed on the partition plate.

[0012] The beneficial effects are as follows: the pressure roller drives the cam to rotate, and the cam intermittently and continuously squeezes and pushes the push rod. At the same time, the push rod pushes the scraper to move back and forth along the guide rod and smooths out the wrinkles on the surface of the aluminum foil. Then, the spring force pushes the pressure roller downward, and the pressure roller flattens the creases on the surface of the aluminum foil, thereby automatically smoothing out the wrinkled parts of the aluminum foil, thus improving production efficiency and product quality.

Detailed Implementation

[0024] Example: A high-frequency cable longitudinal wrapping mold, such as Figures 1-10As shown, the system includes a base 1, a slide rail 2, mold blocks D3, C4, B5, and A6, a fixing frame 7, a support plate 11, a guide rod 12, a scraper 13, a tension spring 14, a pressure roller 8, a spring 9, an electric roller 10, a push rod 15, a cam 16, a fixing frame 17, a cleaning brush 18, a heating pad 19, a partition plate 20, and a conveying pipe 21. A tapered slide rail 2 is provided on the rear top of the base 1. This slide rail 2 gradually narrows from front to back, and molds are slidably mounted on the slide rail 2 from front to back. The system comprises block D3, mold block C4, mold block B5, and mold block A6. Mold block B5 consists of two parts, which are slidably mounted on the left and right sides of slide rail 2. The tapered slide rail 2 controls the gap between the two mold blocks B5, allowing for longitudinal wrapping operations on different cables. Mold blocks D3, C4, and A6 are slidably mounted on the top of slide rail 2. Mold block D3 has a through hole at its bottom and three circular holes in its center. Mold block C4 has an arc-shaped adjustment groove at its bottom. The base 1 has a circular ring at its front end. A fixing frame 7 is fixed inside by bolts. A support plate 11 is installed on the front side of the fixing frame 7. Guide rods 12 are symmetrically arranged on the support plate 11. Scrapers 13 are slidably arranged on the symmetrical guide rods 12. The scrapers 13 are in the shape of an inverted triangle. A tension spring 14 is wound around the guide rods 12. One end of the tension spring 14 is connected to the rear end of the scraper 13, and the other end is connected to the fixing frame 7. An electric roller 10 is rotatably arranged at the bottom inside the fixing frame 7. A pressure roller 8 is slidably and rotatably arranged on the upper side inside the fixing frame 7. Springs 9 are symmetrically arranged on both sides of the roller 8 and between the roller and the fixed frame 7. Cams 16 are symmetrically arranged on both sides of the roller 8. Push rods 15 are symmetrically arranged on both sides of the scraper 13. The rear ends of the symmetrical push rods 15 slide close to the front surface of the cams 16. A fixed frame 17 is arranged on the rear side of the fixed frame 7. Cleaning brushes 18 are symmetrically arranged inside the fixed frame 17. A heating pad 19 is arranged at the bottom of the support plate 11. A partition plate 20 is arranged at the top inside the fixed frame 7. Three conveying pipes 21 are arranged on the partition plate 20.

[0025] In the high-frequency cable longitudinal wrapping process, the cable to be longitudinally wrapped is first fed into the mold block D3 from the front of the conveying pipe 21. Then, aluminum foil is fed into the support plate 11 and pushed between the pressure roller 8 and the electric roller 10. The electric roller 10 then conveys the aluminum foil forward to the bottom through hole of the mold block D3. When wrinkles appear on the surface of the aluminum foil, the heating pad 19 is turned on to heat the aluminum foil through heat transfer from the support plate 11. Then, the pressure roller 8 drives the cam 16 to rotate. The cam 16 drives the scraper 13 to move forward along the guide rod 12 through the pressing push rod 15 and smooths out the wrinkled parts of the aluminum foil. At the same time, the tension spring 14 is stretched, and the cam 16 continues to rotate. When the highest point of the cam 16 slowly moves away from the rear end of the push rod 15, the scraper 13 is pulled back to its original position by the elastic force of the tension spring 14. This process is repeated to effectively smooth out the wrinkled parts of the aluminum foil, thereby improving the efficiency of longitudinal wrapping. The spring force of spring 9 pushes the pressure roller 8 downward, which flattens the creases on the heated aluminum foil surface, thereby improving the quality and aesthetics of longitudinal wrapping. The aluminum foil flattened by the pressure roller 8 passes between the symmetrical cleaning brushes 18 inside the fixed frame 17. At this time, the cleaning brushes 18 clean the top and bottom surfaces of the aluminum foil, cleaning the dust off the surface of the aluminum foil, improving the adhesion of the aluminum foil, and thus improving the quality of the product. Then, the cable and aluminum foil pass through the mold block D3 and enter the mold block C4 again. At this time, the aluminum foil enters the arc-shaped adjustment groove below the mold block C4, and the cable enters the tightening hole in the middle of the mold block C4. At this time, the aluminum foil is in an arc shape, the distance between the cables is reduced, and the aluminum foil is in a semi-enclosed form. Then, the aluminum foil and cable pass through the mold block B5 again. At this time, the aluminum foil shrinks again and wraps the cable. Finally, it passes through the mold block A6 again to make the aluminum foil tightly adhere to the surface of the cable, thereby completing the longitudinal wrapping process.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
