Description

Technical Field

[0001] The present invention relates to the technical field of steel plate roller brushes, and particularly relates to a semi-circular disc steel plate roller brush with convenient brush hair replacement. Background Art

[0002] During the production and use of steel plates, it is necessary to remove rust from the surface of the steel plates. Existing roller brushes for steel plate rust removal are mostly made by sleeving and installing a circular brush disc on the circumferential side of the roller shaft of the brush roller. For the above-mentioned existing roller brushes, during use, if local brush hairs fall off and are severely damaged, and when it is necessary to replace the circular brush disc, the staff needs to disassemble each circular brush disc one by one, and after replacing the corresponding circular brush disc, gradually install each circular brush disc. This kind of roller brush based on a circular brush disc is relatively inconvenient when replacing the brush hairs. To solve the above problems, the present invention provides a convenient detachable steel plate roller brush based on a semi-circular brush disc. Summary of the Invention

[0003] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide a semi-circular disc steel plate roller brush with convenient brush hair replacement. By installing the inner side of the semi-circular brush disc in the annular groove, the limiting plate passes through the limiting hole and extends into the inner part of the tubular shaft, and the connecting piece connects several limiting plates with the tubular shaft, thus solving the technical problems raised in the background art.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a semi-circular disc steel plate roller brush with convenient brush hair replacement, including: a tubular shaft, several semi-circular brush discs installed on the outer side surface of the tubular shaft, and a connecting piece; several annular grooves are evenly arranged on the outer side of the tubular shaft, and the distance between adjacent two annular grooves is close to the width of the annular groove, so as to ensure that the brush filaments of two adjacent semi-circular brush discs can intersect and completely cover each other, achieving a better scraping effect; limiting holes are symmetrically arranged on the bottom surface of the annular groove; actually, the radian between the two limiting holes is 180 degrees. When the limiting plate is matched in the limiting hole as described below, it ensures the stable installation of the semi-circular brush disc.

[0005] A limiting plate is integrally connected to the center position of the inner side of the semi-circular brush disc, a stepped hole is opened at the end of the limiting plate, the inner side of the semi-circular brush disc is installed in the annular groove, and the two semi-circular brush discs in the same annular groove form a circular brush disc, and the brush hair density is set appropriately to ensure that there is no obvious gap between the two semi-circular brush discs, so as not to affect the scraping effect; the limiting plate passes through the limiting hole and extends into the inner part of the tubular shaft; the two limiting plates in the same circular brush disc are located on the same straight line, and the stepped hole on the limiting plate is completely located inside the tubular shaft 1.

[0006] In the locked mode, the connecting piece connects several limiting plates with the tubular shaft; in the unlocked mode, the connecting piece is separated from the limiting plate and the tubular shaft.

[0007] Preferably, the semi-circular brush disk is formed by squeezing a plurality of brush filaments between two semi-circular disks; in fact, the manufacturing process of the semi-circular brush disk is similar to that of the existing annular brush disk, and the brush filaments are arranged sufficiently to ensure that the scraping area of the semi-circular brush disk is sufficient. To ensure the stability of the semi-circular brush disk, the two semi-circular disks can also be fixedly connected by screws.

[0008] Preferably, magnets are embedded at the ends of the semi-circular brush disk, and the magnets at both ends of the semi-circular brush disk attract each other; to ensure that in the unlocking mode, the semi-circular brush disk located in the annular groove will not easily fall out of the annular groove, ensuring stability; in addition, it can be arranged on the outer side surface of the semi-circular disk of the semi-circular brush disk.

[0009] Preferably, the connecting member is a strip-shaped insertion rod formed by alternately connecting a limiting wide block and a narrow block. The limiting wide block corresponds to the width dimension of the wide part of the stepped hole, and the narrow block corresponds to the width dimension of the narrow part of the stepped hole; in fact, the limiting wide block and the narrow block have the same width but different thicknesses; at the same time, the length of the limiting wide block is the same as the width of the annular groove, and the length of the narrow block is the same as the distance between adjacent annular grooves; so that the limiting wide block and the narrow block respectively correspond to the wide part and the narrow part of the stepped hole.

[0010] Preferably, in the locking mode, the limiting wide block of the strip-shaped insertion rod is matched and located in the wide part of the corresponding stepped hole, locking the semi-circular brush disk outside the tubular shaft; in fact, the inner sides of the limiting wide block and the narrow block of the strip-shaped insertion rod are both arc surfaces adapted to the inner side surface of the tubular shaft; that is, when the strip-shaped insertion rod is inserted into the stepped hole, the inner side surface of the strip-shaped insertion rod can fully adhere to the inner side surface of the tubular shaft to ensure that the semi-circular brush disk is stably locked on the tubular shaft without deviation. In the locking mode, due to the limiting effect of the limiting wide block of the strip-shaped insertion rod, it is ensured that all semi-circular brush disks are conveniently and stably locked on the tubular shaft.

[0011] Preferably, in the unlocking mode, the narrow block of the strip-shaped insertion rod corresponds to the narrow part of the stepped hole. When the semi-circular brush disk is pulled out, the limiting plate passes out from the narrow part of the stepped hole; that is, when the semi-circular brush disk is pulled outwards, the corresponding limiting plate can slide out from the narrow part of the stepped hole, thereby facilitating the detachment of the semi-circular brush disk from the tubular shaft; then, keeping the position of the strip-shaped insertion rod unchanged, after the new semi-circular brush disk inserts the limiting plate into the limiting hole, it passes through the narrow part of the stepped hole; finally, the strip-shaped insertion rod is moved so that the limiting wide block of the strip-shaped insertion rod corresponds to the narrow part of the stepped hole, realizing convenient replacement.

[0012] Preferably, two support plates are arranged between two adjacent limiting holes for supporting the limiting wide block of the strip-shaped insertion rod. The support plates are located inside the tubular shaft. The lower surface of the upper support plate is flush with the upper bottom surface of the limiting hole, and the upper surface of the lower support plate is flush with the lower bottom surface of the limiting hole, so as to adapt to the thickness of the limiting wide block and play a real supporting role. When the narrow block of the strip-shaped insertion rod corresponds to the narrow part of the stepped hole, to avoid the suspension of the entire strip-shaped insertion rod, two support plates are arranged to maintain the supporting effect on the strip-shaped insertion rod during the unlocking process, which is convenient and practical. The support plates are arranged as needed. Two support plates are arranged between two adjacent limiting holes at both ends of the tubular shaft to meet the use requirements.

[0013] Preferably, end caps are fixedly installed at both ends of the tubular shaft. The inner ends of the end caps abut against the ends of the strip-shaped insertion rod to prevent the strip-shaped insertion rod from shifting and ensure stability during use.

[0014] The beneficial effects of the present invention are as follows: In the present invention, the inner side of the semi-circular brush disk is installed in the annular groove, and the limiting plate passes through the limiting hole and extends into the tubular shaft. In the locking mode, the limiting wide block of the strip-shaped insertion rod is matched in the wide part of the corresponding stepped hole, and the semi-circular brush disk is locked outside the tubular shaft. In the unlocking mode, the narrow block of the strip-shaped insertion rod corresponds to the narrow part of the stepped hole. When the semi-circular brush disk is pulled, the limiting plate passes through the narrow block of the strip-shaped insertion rod, realizing the convenient disassembly and replacement of the roller brush.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0028] As Figures 1 to 10 shown, the present invention provides a semi-circular ring disk steel roller brush for conveniently replacing brush hairs, including: a tubular shaft 1, a plurality of semi-circular ring brush disks 2 installed on the outer side surface of the tubular shaft 1, and a connecting member. Specifically, the semi-circular ring brush disk 2 is formed by extruding a plurality of brush filaments 21 between two semi-circular ring pieces 22; actually, the manufacturing process of the semi-circular ring brush disk 2 is similar to that of the existing annular brush disk, and the brush filaments 21 are arranged sufficiently to ensure that the scraping area of the semi-circular ring brush disk 2 is sufficient. To ensure the stability of the semi-circular ring brush disk 2, the two semi-circular ring pieces 22 can also be fixedly connected by screws.

[0029] Please refer to Figure 5 shown, a plurality of annular grooves 11 are evenly distributed and opened on the outer side of the tubular shaft 1, and the distance between two adjacent annular grooves 11 is close to the width of the annular groove 11 to ensure that the brush filaments of two adjacent semi-circular ring brush disks 2 can intersect and completely cover each other, achieving a better scraping effect; limiting holes 111 are symmetrically opened on the bottom surface of the annular groove 11; actually, the radian between the two limiting holes 111 is 180 degrees. When the limiting plate 3 is matched in the limiting holes 111 in the following text, it ensures the stable installation of the semi-circular ring brush disk 2.

[0030] Please refer to Figure 7 and Figure 8 As shown, a limiting plate 3 is integrally connected to the center position inside the semi-circular brush plate 2. A stepped hole 31 is opened at the end of the limiting plate 3. The inside of the semi-circular brush plate 2 is installed in the annular groove 11. The two semi-circular brush plates 2 in the same annular groove 11 form a circular brush plate, and the brush hair density is set appropriately to ensure that there is no obvious gap between the two semi-circular brush plates 2, so as not to affect the scraping effect; the limiting plate 3 passes through the limiting hole 111 and extends into the inside of the tubular shaft 1; the two limiting plates 3 in the same circular brush plate are located on the same straight line, and the stepped hole 31 on the limiting plate 3 is completely located inside the tubular shaft 1.

[0031] In the locked mode, the connecting piece connects several limiting plates 3 to the tubular shaft 1; in the unlocked mode, the connecting piece is separated from the limiting plate 3 and the tubular shaft 1. Please refer to Figure 8 As shown, magnets 23 are embedded at the ends of the semi-circular brush plates 2. The magnets 23 at both ends of the semi-circular brush plates 2 attract each other to ensure that in the unlocked mode, the semi-circular brush plates 2 located in the annular groove 11 will not easily fall out of the annular groove 11, ensuring stability; in addition, it can be set on the outer side of the semi-circular piece 22 of the semi-circular brush plate 2. Specifically, please refer to Figure 9 As shown, the connecting piece is a strip-shaped insertion rod 4 formed by staggered connection of a limiting wide block 41 and a narrow block 42. The limiting wide block 41 corresponds to the width dimension of the wide part of the stepped hole 31, and the narrow block 42 corresponds to the width dimension of the narrow part of the stepped hole 31; actually, the limiting wide block 41 and the narrow block 42 have the same width but different thicknesses; at the same time, the length of the limiting wide block 41 is the same as the width of the annular groove 11, and the length of the narrow block 42 is the same as the distance between two adjacent annular grooves 11; so that the limiting wide block 41 and the narrow block 42 respectively correspond to the wide part and the narrow part of the stepped hole 31.

[0032] Please refer to Figure 3 As shown, in the locked mode, the limiting wide block 41 of the strip-shaped insertion rod 4 is fitted inside the wide part of the corresponding stepped hole 31 to lock the semi-circular brush plate 2 outside the tubular shaft 1; actually, the inner sides of the limiting wide block 41 and the narrow block 42 of the strip-shaped insertion rod 4 are both arc surfaces adapted to the inner side surface of the tubular shaft 1; that is, when the strip-shaped insertion rod 4 is inserted into the stepped hole 31, the inner side surface of the strip-shaped insertion rod 4 can fully adhere to the inner side surface of the tubular shaft 1 to ensure that the semi-circular brush plate 2 is stably locked on the tubular shaft 1 without deviation. In the locked mode, due to the limiting effect of the limiting wide block 41 of the strip-shaped insertion rod 4, it is ensured that all the semi-circular brush plates 2 are conveniently and stably locked on the tubular shaft 1.

[0033] Please refer to Figure 3As shown, in the unlocking mode, the narrow block 42 of the bar-shaped insertion rod 4 corresponds to the narrow part of the stepped hole 31. When the semi-circular brush plate 2 is pulled, the limiting plate 3 passes through the narrow block 42 of the bar-shaped insertion rod 4; that is, when the semi-circular brush plate 2 is pulled outwards, the corresponding limiting plate 3 can slide out from the narrow part of the stepped hole 31, thus facilitating the detachment of the semi-circular brush plate 2 from the tubular shaft 1. Then, keeping the position of the bar-shaped insertion rod 4 unchanged, after the new semi-circular brush plate 2 inserts the limiting plate 3 into the limiting hole 111, it passes through the narrow part of the stepped hole 31. Finally, the bar-shaped insertion rod 4 is moved so that the limiting wide block 41 of the bar-shaped insertion rod 4 corresponds to the narrow part of the stepped hole 31, realizing convenient replacement. More specifically, two support plates 5 are arranged between two adjacent limiting holes 111 to support the limiting wide block 41 of the bar-shaped insertion rod 4. The support plates 5 are located inside the tubular shaft 1. The lower surface of the upper support plate 5 is flush with the upper bottom surface of the limiting hole 111, and the upper surface of the lower support plate 5 is flush with the lower bottom surface of the limiting hole 111 to adapt to the thickness of the limiting wide block 41 and play a real supporting role. When the narrow block 42 of the bar-shaped insertion rod 4 corresponds to the narrow part of the stepped hole 31, to avoid the suspension of the entire bar-shaped insertion rod 4, two support plates 5 are arranged to maintain the supporting effect on the bar-shaped insertion rod 4 during the unlocking process, which is convenient and practical. The support plates 5 are arranged as needed. Arranging two support plates 5 between two adjacent limiting holes 111 at both ends of the tubular shaft 1 can meet the use requirements. More specifically, end caps 6 are fixedly installed at both ends of the tubular shaft 1. The inner ends of the end caps 6 abut against the ends of the bar-shaped insertion rod 4 to prevent the bar-shaped insertion rod 4 from shifting and ensure the stability during use.

[0034] When the present invention is in use, the inner side of the semi-circular brush plate 2 is installed in the annular groove 11, and the limiting plate 3 passes through the limiting hole 111 and extends into the tubular shaft 1. In the locking mode, the limiting wide block 41 of the bar-shaped insertion rod 4 is matched in the wide part of the corresponding stepped hole 31 to lock the semi-circular brush plate 2 outside the tubular shaft 1. In the unlocking mode, the narrow block 42 of the bar-shaped insertion rod 4 corresponds to the narrow part of the stepped hole 31. When the semi-circular brush plate 2 is pulled, the limiting plate 3 passes through the narrow block 42 of the bar-shaped insertion rod 4, realizing the convenient disassembly and replacement of the roller brush.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
