Detailed Description

The following describes in detail an embodiment of the present invention with reference to the drawings.

In the embodiment, a dynamic polishing treatment device for a surface scale of a strip is specifically disclosed, as shown in fig. 1 to 6, the specific structure of the device comprises a plurality of polishing units arranged in the feeding direction of the strip, each polishing unit comprises two polishing groups arranged at intervals along the feeding direction of the strip, each polishing group comprises two polishing discs 6 arranged at intervals horizontally along the width direction of the strip, and abrasive filaments 601 extending downwards are densely distributed on the bottom surfaces of the polishing discs 6; two grinding disks 6 in the same grinding group can move back and forth along the width direction of the plate strip to adjust the corresponding grinding area of each grinding disk 6 on the plate strip, and the two grinding groups are arranged in a staggered mode along the width direction of the plate strip.

In the actual production of the plate belt grinding brush, the grinding wires 601 are densely connected to the bottom surface of the grinding disc 6 to form a surface contact grinding brush mode, and compared with a traditional line contact grinding brush mode formed by a scale breaking roller, the surface contact grinding brush mode has a better grinding brush effect. An empty area 602 which is not connected with the abrasive wires 601 is reserved in the middle of the abrasive disc 6 to reduce the friction force when the abrasive disc 6 translates along the width direction of the plate strip; the remaining empty space 602 may also temporarily contain abraded scale and abrasive filament 601 debris, preventing it from becoming lodged in the abrasive filament 601. Without the empty space 602, scale and debris may not be removed in a timely manner, and may be more difficult to remove at the center of the brush plate 6, which may affect the effectiveness of the polishing process. Then, the two grinding and brushing discs 6 are combined into a grinding and brushing group, and the two grinding and brushing groups are combined into a grinding and brushing unit, so that oxide skin on the surface of the plate strip can be sufficiently ground when the plate strip is fed through the plurality of grinding and brushing units. Because two scrubbing disks 6 in the scrubbing group have certain clearance, have certain scrubbing dead angle when polishing, can't cover the slab band completely along slab band width direction, consequently the crisscross mode of arranging of scrubbing group can make the scrubbing disk 6 in another group fill this clearance for scrubbing disk 6 in two scrubbing groups can form the scrubbing at no dead angle to the slab band surface, has further improved the effect of scrubbing.

The structure of the grinding and brushing unit comprises a machine base 1, wherein the machine base 1 comprises a main beam 101 and two upright posts 102 symmetrically connected to the bottom surface of the main beam 101, the section of the main beam 101 is U-shaped, and the upper end of the main beam 101 is provided with two mounting beams 103 along the length direction thereof so as to respectively form corresponding mounting intervals for mounting a grinding and brushing group on the side wall of the main beam 101; a plate belt feeding channel 106 is formed between the two upright posts 102 and below the main beam 101.

The strip travels along the strip feed channel 106 as it is fed and is then sanded by a sanding block above it. Wherein the main beam 101 is U-shaped so that two mounting beams 103 are formed to be able to mount two corresponding sets of brushes, respectively, thereby forming a complete brush unit. When the grinding brush is installed, due to the interval of the installation beams 103, the installation and the disassembly among the small groups of the grinding brushes cannot be influenced.

The supporting seat 3 can be used for being connected to the mounting beam 103, and is arranged on the supporting brush driving part 2 and the brush disk 6, and can also drive the two to move along the length direction of the mounting beam 103, so as to adjust the corresponding brush area of the brush disk 6.

The concrete connection mode of supporting seat 3 does: the top surface and the outer side wall of the mounting beam 103 are both connected with a first slide rail 104 along the length direction; the supporting seat 3 comprises an upper supporting seat 301 arranged above the mounting beam 103 and a lower supporting seat 302 arranged on the outer side wall of the mounting beam 103, the upper supporting seat 301 and the lower supporting seat 302 form a 7-shaped hanging connection on the mounting beam 103, and the bottom surface of the upper supporting seat 301 and the inner side of the lower supporting seat 302 are both connected with a first sliding block 105 matched with a first sliding rail 104.

The upper stay seat 301 and the lower stay seat 302 are connected to the top surface and the outer side wall of the installation beam 103, respectively, to form bidirectional supports in the up-down direction and the front-rear direction, not only making the connection more stable, but also more stable when the adjustment position is moved. If adopt traditional connected mode, hang supporting seat 3 and connect in the main beam 101 below, under long-time brush, brush drive division 2 and brush plate 6 wholly can take place to warp the slope, can influence the effect of brush. The upper supporting seat 301 and the lower supporting seat 302 are integrally connected in a 7-shaped hanging mode, so that the installation and the disassembly are more convenient, the connection is more stable, and the inclination condition cannot occur.

Before the plate strip is ground, the position of a grinding disc 6 can be adjusted in advance according to the width of the plate strip, so that the grinding disc 6 can be completely covered along the width direction of the plate strip, grinding without dead corners is guaranteed, the plate strip is ground in place, the movement of the plate strip is mainly realized by the driving of a second driving mechanism 5, the second driving mechanism 5 comprises a screw rod 501 arranged along a mounting beam 103 and a second motor 502 driving the screw rod 501 to rotate, a motor mounting seat 503 is further mounted on the side wall of the mounting beam 103, a bearing seat 504 used for connecting and supporting the screw rod 501 is arranged on the motor mounting seat 503, and the second motor 502 is also erected on the motor mounting seat 503; the side wall of the upper support seat 301 is connected with a screw rod sliding sleeve 505 sleeved on the screw rod 501.
