Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, and in particular to a fireproof cable coating equipment. Background Technology

[0002] In the production process of fireproof cables, fireproof coating needs to be applied to the surface of the cable. Common coating equipment includes a nozzle and a scraper. The nozzle is responsible for spraying the coating, and the scraper is used to scrape off the excess coating. The scraper needs to be installed coaxially with the cable to ensure uniform coating. However, since the scraper is installed inside the equipment in a closed or semi-closed state, its position is not easy to observe, and it is difficult to accurately adjust and center it during installation. The existing equipment lacks effective testing methods. The scraper is used directly after installation, which can easily lead to positional deviations. These deviations can cause uneven coating distribution, affecting the fire resistance of the cable and potentially causing the scraper to wear out too quickly in certain areas. Each time the scraper is reinstalled after cleaning and maintenance, repeated adjustments are required, which affects production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that lack coaxiality detection of scrapers, and to propose a fireproof cable coating device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fire-resistant cable coating device, comprising a housing; Multiple nozzles arranged in a ring at equal intervals are all located inside one side of the housing. The outer wall of the housing is provided with a connection end corresponding to the nozzle, which is used to connect to an external paint supply system. The nozzles spray fire-retardant paint onto the surface of the cable. A circular scraper is disposed on the other side inside the housing. Two embedded ring seats are fixed to the inner wall of the housing. The circular scraper is located between the two embedded ring seats and is used to scrape off excess coating from the surface of the cable. Multiple arc-shaped plates are used to detect the position of a circular scraper. A sliding ring seat is slidably provided on the inner wall of the housing along the axial direction. A side ring seat is fixed on the side wall of the sliding ring seat. Multiple limiting rods are fixed on the inner wall of the side ring seat and arranged equidistantly in a ring. A sleeve is slidably sleeved on the outer wall of the limiting rod. One end of the multiple sleeves is fixed to the outer wall of the multiple arc-shaped plates respectively. Multiple straight guide holes corresponding to the sleeves are opened on the side wall of the sliding ring seat. A rotating ring seat is rotatably connected to the side wall of the sliding ring seat away from the side ring seat. Multiple oblique guide holes corresponding to the straight guide holes are opened on the side wall of the rotating ring seat. A guide rod is fixed to the other end of the sleeve. One end of the guide rod extends into the interior of the adjacent straight guide hole and oblique guide hole. The rotation of the rotating ring seat drives the arc-shaped plates to move to form a ring to detect the position of the circular scraper. Multiple fixing rods are provided. The inner wall of the housing is provided with an axially sliding mounting ring seat. One end of each fixing rod is fixed to the side wall of the mounting ring seat and arranged in a ring at equal intervals. The side wall of the annular scraper is provided with multiple fixing holes corresponding to the fixing rods. The fixing rods are inserted into the fixing holes to fix the annular scraper.

[0005] In one possible design, the fixing rod and the arc-shaped plate are located on both sides of the annular scraper, with the fixing rod located on the side of the annular scraper closer to the nozzle. The rotating ring seat has multiple limiting holes on its sidewall and on the outer side, corresponding to the fixing rod. The fixing rod is inserted into the limiting holes to limit the rotation ring seat.

[0006] In one possible design, the outer wall of the housing has an installation hole that serves as an assembly channel for a circular scraper, and an arc-shaped partition is slidably provided on the inner wall of the top of the housing to cover the installation hole. The arc-shaped partition is fixed to the outer wall of the mounting ring seat.

[0007] In one possible design, a first handle is fixed to the outer wall of the arc-shaped partition, a transverse sliding hole is provided on the top of the housing as a sliding channel for the first handle, a second handle is fixed to the outer wall of the rotating ring seat, and an L-shaped sliding hole is provided on the outer wall of the housing as an active channel for the second handle. The arc-shaped partition and the rotating ring seat are moved by the first handle and the second handle respectively.

[0008] In one possible design, the inner wall of the mounting hole is provided with a threaded rod, one end of which is threaded through the transverse sliding hole and threaded to the inside of the first handle, and the other end of the threaded rod is provided with a screwing end, which can be screwed to fix the first handle.

[0009] In one possible design, the housing has waste inlets on its bottom inner wall below the nozzle and the annular scraper for collecting residual paint.

[0010] In one possible design, the housing is provided with two guide rollers on the same side of the nozzle to guide the cable into the equipment. The cable passes through the guide rollers, the nozzle and the annular scraper in sequence to complete the coating.

[0011] In this application, during actual use, the cable passes sequentially through the nozzle and the annular scraper inside the equipment. The nozzle sprays the paint onto its surface, and the annular scraper then scrapes off any excess paint from the surface. When installing the annular scraper, the operator assembles the annular scraper into the interior of the housing through the mounting hole, positioning it between the two inserting ring seats. Then, the second handle is moved along the transverse section of the L-shaped sliding hole, causing the rotating ring seat to rotate. The rotating ring seat will then rotate the oblique guide hole on the surface, thereby changing the position of the connection between the straight guide hole and the oblique guide hole, causing the guide rod to move towards its center. The guide rod will then move the arc plate through the sleeve, assembling multiple arc plates into a ring that matches the inner wall of the annular scraper. Next, the second handle is moved along the vertical section of the L-shaped sliding hole, causing it to move the ring composed of arc plates and insert it into the interior of the annular scraper. This is used to check the position of the annular scraper after installation, ensuring that it is in a coaxial position. After that, the ring can be moved and reset. Then, move the No. 1 handle along the horizontal sliding hole, thereby moving the arc-shaped partition and multiple oblique guide holes. The arc-shaped partition will close the mounting hole, initially limiting the circular scraper. At the same time, the fixing rod will be inserted into the fixing hole to fix the circular scraper. After passing through the fixing hole, the fixing rod will be inserted into the limiting hole to limit the rotating ring seat, thus preventing rotation or displacement during use and ensuring stability. Then, screw the threaded rod into the No. 1 handle and fix it.

[0012] In this utility model, the fireproof cable coating equipment can quickly assemble the scraper into a ring for positioning and detection after assembly by means of an arc plate and a guide mechanism, so as to perform coaxial detection. After the detection is completed, it can also be quickly reset to open the original cable channel. In this utility model, the fireproof cable coating equipment can achieve quick and easy installation of the scraper by means of a fixing rod, and at the same time, it can limit and fix the positioning arc to ensure its stability during use. In this invention, by setting a detection function for the installation position of the scraper, the scraper is ensured to be coaxial with the cable axis, thus ensuring uniform and consistent coating, avoiding unnecessary uneven coating and localized wear, and improving the production qualification rate.

The length direction of the limiting rods 18 is located in the radial direction of the sliding ring seat 16. A sleeve 21 is slidably sleeved on the outer wall of each limiting rod 18. One end of the sleeve 21 is fixed to the outer wall of the arc plate 22. Multiple straight guide holes 17 are opened on the side wall of the sliding ring seat 16. The straight guide holes 17 are strip-shaped holes that extend radially along the sliding ring seat 16 and penetrate through the thickness direction of the sliding ring seat 16. Each straight guide hole 17 corresponds to a sleeve 21. The side wall of the sliding ring seat 16 away from the side ring seat 19 is rotatably connected to the rotating ring seat 13 by a sleeve with an L-shaped cross section. Multiple oblique guide holes 15 are provided on the side wall of the rotating ring seat 13. The oblique guide holes 15 are provided through the thickness direction of the rotating ring seat 13. Each oblique guide hole 15 corresponds to a straight guide hole 17. The other end of the sleeve 21 is fixed with a guide rod 20. The guide rod 20 is provided along the axis of the sliding ring seat 16. The end of the guide rod 20 away from the sleeve 21 is inserted into both the straight guide hole 17 and the oblique guide hole 15.

[0019] The arc plate 22 is shaped by cutting the entire ring into multiple arc-shaped structures at equal intervals, which are then assembled to form a complete ring.

[0020] refer to Figure 5 In addition, an installation ring seat 23 is slidably mounted on the inner wall of the housing 1 along the axial direction by a guide strip. Multiple fixing rods 25 are fixed to the side wall of the installation ring seat 23 near the annular scraper 24 and are arranged in a ring at equal intervals.
