Description

Technical Field

[0001] This invention relates to the field of wire rod rust removal technology, specifically to a double-brush wire rod rust removal device. Background Technology

[0002] Before use, wire rods are often subjected to rust removal and grinding. In the current rust removal process, to ensure that the rust around the wire rod is completely removed, multiple rust removal rollers are set in the direction of wire rod movement to remove rust from different parts of the wire rod cross-section. This ensures that the rust removal rollers can cover the circumference of the wire rod and achieve efficient cleaning. However, this design has shortcomings. First, to ensure the grinding effect, multiple spaced rust removal rollers need to be arranged around the wire rod, which is costly. In addition, the multiple rust removal rollers arranged around the wire rod need to be repositioned multiple times to ensure that the brush strips on each rust removal roller are in close contact with the wire rod. Moreover, since there is always a gap between every two adjacent rust removal rollers, the gap area is easy to miss during grinding, making it difficult to ensure that the wire rod is completely ground clean. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a double-roller brush wire rod rust removal device. By installing rust removal brush assemblies located on both sides of the wire rod inside the rust removal pipe, the arc-shaped brush discs of the two rust removal brush assemblies can perform all-round grinding on the outer periphery of the wire rod, achieving rust removal and cleaning without dead angles and improving the grinding effect of the wire rod.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a double-roller brush wire rod rust removal device, including a rust removal pipe, in which the wire rod can travel along its own length. Along the traveling direction of the wire rod, two spaced rust removal brush assemblies are provided in the rust removal pipe, and the two rust removal brush assemblies are respectively located on opposite sides of the wire rod. The rust removal brush assembly includes a brush roller rotatably connected in the rust removal pipe and multiple arc-shaped brush discs evenly distributed circumferentially on the rotating brush roller. The arc-shaped brush discs are semi-circular or slightly arc-shaped, and multiple brush bristles are densely arranged on the inner ring surface of the arc-shaped brush discs. As the wire rod travels, the two brush rollers rotate, causing multiple bristles on the two rust-removing brush assemblies to clean the outer periphery of the wire rod together.

[0005] Preferably, it also includes a drive mechanism that can drive the two brush rollers to rotate simultaneously, so as to ensure that the two brush rollers rotate at the same time.

[0006] Preferably, each brush roller has a roller shaft at both ends, and the roller shaft is rotatably connected to the rust removal pipe; the drive mechanism includes a servo motor and a synchronization mechanism, the synchronization mechanism includes a synchronization wheel concentrically connected to each roller shaft, and the two synchronization wheels are connected by a cross "8" shaped synchronization belt; the servo motor is connected to any roller shaft at the end of any brush roller.

[0007] Preferably, multiple brush filaments on each arc-shaped brush disc form a roller brush notch with a semi-circular or slightly curved cross-section. On each brush roller, the roller brush notches on multiple arc-shaped brush discs together constitute an annular roller brush groove corresponding to the position of the wire rod; so as to allow the wire rod to pass through the annular roller brush groove when traveling, and to minimize the resistance of the brush filaments to the travel of the wire rod.

[0008] Preferably, the outer periphery of the brush roller is provided with an annular groove with an arc-shaped cross-section, and multiple arc-shaped brush discs with bristles are evenly distributed circumferentially inside the annular groove; the annular groove with an arc-shaped cross-section can provide space to accommodate the arc-shaped brush discs and match the outer contour of the arc-shaped brush discs.

[0009] Preferably, the annular groove has multiple slots evenly distributed along the circumference to match the arc-shaped brush disk, and the opposite end of the brush bristles on each arc-shaped brush disk is inserted into the corresponding slot.

[0010] Preferably, each arc-shaped brush disk is connected to the brush roller by a fastening structure, which includes a limiting sleeve and two symmetrical limiting parts extending along the axial direction of the brush roller on the arc-shaped brush disk. The limiting sleeve is simultaneously fitted onto the limiting parts of multiple arc-shaped brush disks.

[0011] Preferably, the outer periphery of the brush roller is provided with an annular groove with an arc-shaped cross-section. Multiple slots matching the arc-shaped brush disks are evenly distributed circumferentially within the annular groove. The end of each arc-shaped brush disk without bristles is inserted into the corresponding slot. A central hole is provided at the center of the brush roller end face, and the slots communicate with the central hole. The limiting part is located inside the central hole. The limiting sleeve is fitted from the central hole at the end of the brush roller onto the limiting parts of the multiple arc-shaped brush disks. The central hole can be used to pass through the roller shaft, and a space is formed between the roller shaft and the central hole to facilitate the insertion of the limiting sleeve, allowing the brush roller to rotate normally. The insertion of the limiting sleeve also forms a radial limit on each arc-shaped brush disk, which is an ingenious design.

[0012] Preferably, a flange is connected to the outer end of the limiting sleeve. The flange is connected to the end of the brush roller and closes the opening of the central hole. This not only limits the arc-shaped brush plate but also seals the opening of the central hole, improving the sealing performance while making the structure of the brush roller more compact.

[0013] Preferably, the brush roller has symmetrically arranged limiting structures along the axial direction on its roller body. The limiting structures include multiple limiting slots evenly distributed circumferentially on the brush roller, with each limiting slot communicating with and corresponding to a slot. Each limiting slot passes through the corresponding end of the brush roller. Each arc-shaped brush disc is connected to a limiting insert on its outer side, and the limiting insert is installed in the limiting slot. Both ends of the brush roller are provided with limiting end caps, which include a circular end plate and an annular stop extending from the edge of the circular baffle. The annular stop fits onto the brush roller and restricts the limiting insert from radially disengaging from the limiting slot. The circular end plate is fixed to the end of the brush roller and restricts the limiting insert from axially disengaging from the limiting slot. This provides axial and radial limiting for the arc-shaped brush disc, ensuring that the arc-shaped brush disc is stably connected to the brush roller. At the same time, the limiting end caps can cover the openings of the limiting slots at both ends of the brush roller and on the roller body, thus providing a certain degree of protection.

[0014] The beneficial effects of this invention are as follows: This invention relates to a rust-removing brush assembly located on both sides of a wire rod within a rust-removing pipe. The assembly includes a rotating brush roller and multiple arc-shaped brush discs with bristles mounted on the roller. The arc-shaped brush discs are semi-circular or slightly curved, and the brushing area formed by the bristles on these discs is also semi-circular or slightly curved, capable of covering the outer periphery of the wire rod beyond a semi-circular area. As the brush rollers rotate, both rotating rollers simultaneously polish both sides of the traveling wire rod, ensuring that the arc-shaped brush discs of the two rust-removing brush assemblies can perform all-around polishing of the wire rod's outer periphery, achieving thorough rust removal and cleaning, and improving the polishing effect of the wire rod.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1-10 As shown, this invention provides a double-roller brush wire rod rust removal device, including a rust removal pipe 1, a wire rod 2 that can travel along its own length within the rust removal pipe 1, and two spaced-apart rust removal brush assemblies arranged within the rust removal pipe 1 along the traveling direction of the wire rod 2, the two rust removal brush assemblies being located on opposite sides of the wire rod 2; for example, the two rust removal brush assemblies can be located on the upper and lower sides of the wire rod 2, or on the left or right side of the wire rod 2, respectively; the rust removal brush assembly includes a brush roller 3 rotatably connected within the rust removal pipe 1 and a plurality of brushes evenly distributed circumferentially. The arc-shaped brush disk 4 on the rotating brush roller is semi-circular or slightly curved. The arc-shaped brush disk 4 is also a circular ring formed by cutting off part of the circular ring. At the same time, the arc corresponding to the circular ring is a semi-circular arc or a slightly curved arc. The slightly curved arc means that the extension angle of the arc-shaped brush disk 4 exceeds 180° but is less than 360°. The arc-shaped brush disk 4 has an arc-shaped inner ring surface and an outer ring surface. Multiple brush filaments 41 are densely arranged on the inner ring surface of the arc-shaped brush disk 4. Multiple brush filaments 41 form an arc-shaped brushing part on the inner ring surface. Multiple brushing parts form a ring of brushing area on the brush roller 3. As the wire rod 2 moves forward, its two sides are surrounded by corresponding brushing areas. At the same time, since the arc-shaped brush disk 4 is semi-circular or slightly curved, the brushing part composed of multiple brush bristles 41 covers the outer periphery of the wire rod 2 beyond the semi-circular area. In this way, the two brushing areas can fully cover the outer periphery of the wire rod 2. When the two brush rollers 3 rotate, the multiple brush bristles 41 on the two rust removal brush assemblies work together to clean the outer periphery of the wire rod 2, so that the outer periphery of the wire rod 2 is cleaned without dead angles. In addition, the two rust removal brush assemblies are spaced apart, which also facilitates the discharge of rust generated during grinding and prevents it from accumulating on the brush rollers 3 or the arc-shaped brush disk 4.

[0019] Furthermore, such as Figure 1-3 As shown, each brush roller 3 has a roller shaft 33 at both ends, and the roller shaft 33 is rotatably connected to the rust removal pipe 1; the double roller brush strip rust removal equipment also includes a drive mechanism, which can drive the two brush rollers 3 to rotate simultaneously; to ensure that the two brush rollers 3 rotate simultaneously; the drive mechanism can be two corresponding servo motors 7 that drive the corresponding brush rollers 3 to rotate, but the cost of two servo motors 7 is too high, so the drive mechanism in this embodiment includes a servo motor 7 and a synchronization mechanism. The synchronization mechanism includes a synchronization wheel 72 that is concentrically connected to each roller shaft 33, and the two synchronization wheels 72 are connected by a cross "8" shaped synchronization belt; the servo motor 7 is connected to any roller shaft 33 at the end of any brush roller 3; so that the two brush rollers 3 rotate in opposite directions, and the arc-shaped brush discs 4 installed on the two brush rollers 3 simultaneously brush the strip 2.

[0020] Furthermore, multiple brush bristles 41 on each arc-shaped brush disk 4 are arranged on its inner ring surface, which is also semi-circular or slightly curved, thus forming a roller brush notch with a cross-section of semi-circular or slightly curved. On each brush roller 3, the roller brush notches on multiple arc-shaped brush disks 4 together form an annular roller brush groove corresponding to the position of the wire rod 2. In addition to forming a good full-coverage brushing effect on the outer periphery of the wire rod 2, it also allows the wire rod 2 to pass through the annular roller brush groove when it travels, avoiding excessive bending of some brush bristles 41 after being subjected to the force of the wire rod 2, and minimizing the resistance of the brush bristles 41 to the travel of the wire rod 2.

[0021] Furthermore, such as Figure 5-7 As shown, to facilitate the placement of the arc-shaped brush disk 4 and ensure sufficient installation space and contact area between the arc-shaped brush disk 4 and the brush roller 3, an annular groove 31 with an arc-shaped cross-section is provided on the outer periphery of the brush roller 3. Multiple arc-shaped brush disks 4 with brush bristles 41 are evenly distributed circumferentially within the annular groove 31. The annular groove 31 with an arc-shaped cross-section can provide space and sufficient contact area to accommodate the arc-shaped brush disk 4 and match its outer contour. Specifically, multiple slots 311 matching the arc-shaped brush disk 4 are evenly distributed circumferentially within the annular groove 31. The opposite end of the brush bristles 41 on each arc-shaped brush disk 4 is inserted into the corresponding slot 311, restricting the arc-shaped brush disk 4 from moving circumferentially along the brush roller 3.

[0022] Furthermore, such as Figure 4-10 As shown, to limit the radial movement of the arc-shaped brush disk 4 on the brush roller 3, each arc-shaped brush disk 4 is connected to the brush roller 3 by a fastening structure. The fastening structure includes a limiting sleeve 5 and two symmetrical limiting parts 42 extending from the arc-shaped brush disk 4 along the axial direction of the brush roller 3. There are two limiting sleeves 5 to correspond to the two symmetrical limiting parts 41. A limiting groove 421 is formed between the limiting part 41 and the arc-shaped brush disk 4. The limiting sleeve 5 is simultaneously fitted onto the limiting parts 42 of multiple arc-shaped brush disks 4. The outer periphery of the brush roller 3 is provided with an annular groove 31 with an arc-shaped cross-section. Multiple slots 311 matching the arc-shaped brush disk 4 are evenly distributed circumferentially in the annular groove 31. Each arc-shaped brush disk 4 is not provided with One end of the bristles 41 is inserted into the corresponding slot 311. A central hole 313 is provided at the middle of the end face of the brush roller 3. The slot 311 is connected to the central hole 313 and forms a connecting opening 312. The limiting part 42 passes through the connecting opening 312 and is located inside the central hole 313. The limiting sleeve 5 is fitted from the central hole 313 at the end of the brush roller 3 and simultaneously onto the limiting parts 42 of multiple arc-shaped brush disks 4. The central hole 313 can be used to pass through the roller shaft 33. A space is formed between the roller shaft 33 and the central hole 313 to facilitate the insertion of the limiting sleeve 5, ensuring that the brush roller 3 can rotate normally. The limiting sleeve 5 is inserted to form a radial limit on each arc-shaped brush disk 4. The design is ingenious and achieves multiple benefits.

[0023] Furthermore, in this embodiment, the outer end of the limiting sleeve 5 is connected to a flange 51, which is connected to the end of the brush roller 3 and closes the opening of the central hole 313. The connection method is screw connection; so as to facilitate the replacement of the arc-shaped brush disk 4 after use; the fixed limiting sleeve 5 can not only limit the arc-shaped brush disk 4, but also seal the opening of the central hole 313, improve the sealing performance, and make the structure of the brush roller 3 more compact.

[0024] Furthermore, to create a double-limiting effect on the multiple arc-shaped brush discs 4 and make their connection with the brush roller 3 more stable, a limiting structure is symmetrically provided along the axial direction on the roller body of the brush roller 3. The limiting structure includes multiple limiting slots 32 evenly distributed circumferentially on the brush roller 3. The limiting slots 32 are connected to the slots 311 and correspond one-to-one. Each limiting slot 32 passes through the corresponding end of the brush roller 3. A limiting insert 43 is connected to the outer side of each arc-shaped brush disc 4. The limiting insert 43 is installed in the limiting slot 32. Both ends of the brush roller 3 are provided with limiting end caps 6. The limiting end caps 6 include a circular end plate and an annular stop extending from the edge of the circular baffle. The annular stop fits on the roller body of the brush roller 3 and restricts the limiting insert 43 from radially disengaging from the limiting slot 32. The circular end plate is fixed to the brush roller 3. The end of the roller 3 is limited by the limiting insert 43 which axially disengages from the limiting slot 32; the fixing method is also screw connection, so as to facilitate the replacement of the arc-shaped brush disk 4 after use; the circular end plate and the annular stop respectively limit the arc-shaped brush disk 4 in the axial and radial directions, so that the arc-shaped brush disk 4 is stably connected to the brush roller 3, forming another layer of limitation for the arc-shaped brush disk 4, ensuring its connection stability. At the same time, the limiting end cover 6 can cover the openings of the limiting slot 32 at both ends of the brush roller 3 and on the roller body, which also plays a certain protective role; when it is necessary to replace the arc-shaped brush disk 4, the limiting end cover 6 and the limiting sleeve 5 can be removed, and multiple arc-shaped brush disks 4 can be pulled out one by one for replacement. Then, the new arc-shaped brush disk 4 can be installed on the brush roller 3, and the limiting sleeve 5 and the limiting end cover 6 can be installed in sequence.

[0025] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
