Description

Technical Field

[0001] The utility model relates to the technical field of strip steel processing equipment, in particular to a strip steel edge trimming device. Background Art

[0002] Strip steel is a thin plate-shaped steel material rolled by a rolling mill. After the strip steel is produced, it is generally rolled into a steel coil by a coiler. During the transportation and lifting of the steel coil, bumps are inevitable on its edges. And according to different usage requirements, the strip steel needs to be cut before use. At this time, the edge of the strip steel needs to be cut, so that the strip steel cutting knife can be adjusted to the appropriate size, and the damaged strip steel can be cut off. The strip steel is cut by the cutting knife. The strip steel passes through the cutting knife under the conveying mechanism. The rotating cutting knife cuts the edge of the strip steel. After a period of cutting work, small pieces of steel chips are often adhered to the blade of the cutting knife. These steel chips will affect the subsequent strip steel cutting effect, resulting in burrs and warping on the edges of the strip steel after cutting, which seriously affects the quality of the strip steel after cutting and brings great inconvenience to production.

The cutting knife 4 is installed on the driving roller 6. A mounting cross bar 7 is provided on the vertical plate 5 at a position corresponding to one side of the cutting knife 4, and the cleaning component is detachably mounted on the mounting cross bar 7.

[0023] The cleaning assembly includes a cleaning block 8, one end of which is provided with an avoidance groove, the blade portion of the cutting knife 4 is located in the avoidance groove, and a scraping block 9 is also provided in the avoidance groove to fit the cutting knife 4, the scraping block 9 is adapted to the shape of the blade portion of the cutting knife 4, a socket is provided on the mounting cross bar 7, the other end of the cleaning block 8 is plugged into the socket, and the cleaning block 8 is fixedly connected to the mounting cross bar 7 by a quick-release pin 10.

[0024] A limit stopper 11 is arranged at one end of the cleaning block 8 passing through the installation cross bar 7 , and the limit stopper 11 is used to limit the installation of the cleaning block 8 .

[0025] The quick-install pin 10 includes a pin rod 10a that simultaneously passes through the mounting cross bar 7 and the cleaning block 8. The mounting cross bar 7 and the cleaning block 8 are provided with pin holes in the vertical direction for facilitating the insertion of the pin rod 10a. The upper end of the pin rod 10a is provided with a rod head 10b. The diameter of the rod head 10b is larger than the rod diameter of the pin rod 10a. The part of the pin rod 10a extending above the mounting cross bar 7 is sleeved with a telescopic spring 12. One end of the telescopic spring 12 abuts against the rod head 10b, and the other end of the telescopic spring 12 abuts against the top of the mounting cross bar 7. A limiting convex head 10c is provided on one side of the lower end of the pin rod 10a. A first slide groove 7a is provided on the mounting cross bar 7 at the position corresponding to the pin hole, and a second slide groove 8a is provided on the cleaning block 8 at the position corresponding to the pin hole. The first slide groove 7a and the second slide groove 8a cooperate with each other to form a channel for facilitating the upper and lower sliding of the limiting convex head 10c.

[0026] The bottom of the mounting cross bar 7 is provided with a positioning groove 7b at a position corresponding to the pin hole. The positioning groove 7b is arranged on a side opposite to the position of the first sliding groove 7a, and the limiting protrusion 10c is inserted into the positioning groove 7b.

[0027] When installing the cleaning component, first insert the cleaning block 8 along the insertion hole on the mounting cross bar 7. At this time, one end of the cleaning block 8 with the limiting stopper 11 abuts against the side wall of the mounting cross bar 7. At this time, one end of the cleaning block 8 with the scraping block 9 is located on both sides of the blade of the cutting knife 4. Then, the pin rod 10a of the quick-install pin 10 is inserted along the pin hole on the mounting cross bar 7. During the insertion process, the limiting protrusion 10c at the lower end of the pin rod 10a is aligned with the first slide groove 7a on the mounting cross bar 7 and inserted. At this time, the pin rod 10a is inserted along the pin hole, and the limiting protrusion 10c passes through the first slide groove 7a and the second slide groove 8a in sequence, and the limiting protrusion 10c passes through the first slide groove 7a and the second slide groove 8a in sequence. c extends out from the lower end of the mounting cross bar 7, and as the pin rod 10a passes through the entire mounting cross bar 7, the rod head 10b of the pin rod 10a cooperates with the upper end of the mounting cross bar 7 to compress the telescopic spring 12, and then the pin rod 10a is rotated so that the limiting protrusion 10c rotates to the positioning groove 7b on the opposite side of the first slide groove 7a. When the pin rod 10a is released, under the action of the telescopic spring 12, the limiting protrusion 10c is stuck in the positioning groove 7b, thus completing the installation and fixation of the cleaning assembly. The cleaning assembly is installed by the quick-install pin 10, which is convenient for disassembly and assembly of the cleaning assembly. When the scraper block 9 is worn too much, it is convenient to remove it for replacement.

[0028] The cutting roller 3 is provided with cutting grooves 3a at both ends thereof, and the cutting blade 4 is installed at a position corresponding to the cutting groove 3a.

[0029] A driving motor 12 is also provided on one side of the vertical plate 5 . The rotating shaft of the driving motor 12 is connected to the driving roller 6 . The driving motor 12 controls the driving roller 6 to rotate, thereby causing the cutting blade 4 to rotate.

[0030] A plurality of nip rollers 13 are evenly arranged between the vertical plates 5 , and a feeding gap is arranged between the nip rollers 13 and the conveying rollers 2 , through which the strip steel passes.

[0031] The working principle of the utility model is as follows: the steel strip is conveyed at the gap between the conveying roller 2 and the pressing roller 13, and then the driving motor 12 is started and controlled to rotate the cutting knife 4. When the steel strip is conveyed to the position of the cutting roller 3, the cutting knife 4 will cut the edge of the steel strip. While the cutting knife 4 is cutting, the blade of the cutting knife 4 will rotate in the scraper block 9, and the scraper block 9 is fitted with the cutting knife. In this way, the steel chips adhered to the cutting knife 4 will be scraped off by the scraper block 9, thereby ensuring the cleanliness of the surface of the cutting knife 4, avoiding the influence of steel chips on the cutting work of the steel strip, and ensuring the quality of the steel strip after cutting.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
