Description

Technical Field

[0001] The invention relates to the technical field of cold rolling mills, in particular to a self-adjusting roller cleaning device for cold rolling mills. Background Art

[0002] The cold rolling mill is a new type of steel bar cold rolling processing equipment. During the rolling process of cold-rolled ribbed steel bars, the cold rolling mill can simultaneously cold-process the warp and weft directions of the parent material. On the premise of retaining the relative balance and stability of the product in the center area of ​​the original cross-section, while improving the tensile and compressive strength, it still retains sufficient elongation performance. The cold rolling mill needs to clean the cold rolling rollers through the roller cleaning device when working.

[0003] For example, Chinese patent publication number "CN216801121U" discloses a "self-adjusting roller cleaning device for a cold rolling mill," the main structure of which includes a frame, a cold rolling roller mounted on the top lower surface and the bottom upper surface of the frame, and a mounting plate provided on one side of the cold rolling roller, with a cylinder mounted on one side surface of the mounting plate. The self-adjusting roller cleaning device for a cold rolling mill uses a cylinder to drive a connecting plate to move, and simultaneously, the connecting plate drives a baffle to move via a connecting block, so that a fixed plate on one side of the baffle moves. When a first scraper and a second scraper on a side surface of the fixed plate abut against the cold rolling roller, dust and residual debris on the cold rolling roller can be scraped off, preventing dust and debris from remaining on the cold rolling roller and affecting its use. The coordinated use of the cylinder, the connecting plate, and the connecting block can automatically adjust the positions of the first scraper and the second scraper on a side surface of the fixed plate, thereby facilitating the cleaning of dust and debris on the cold rolling roller and improving its use effect.

[0004] However, when the above-mentioned self-adjusting roller cleaning device for the cold rolling mill scrapes dust off the cold rolling roller, it uses a scraper with a pointed end to perform contact scraping. This method has the following disadvantages: if the scraping effect is to be enhanced, the contact pressure of the scraper on the cold rolling roller must be increased, and this pressure can easily cause scratches on the surface of the cold rolling roller, resulting in scratches on the surface of the cold rolling roller and reducing its working accuracy; if the occurrence of scratches on the cold rolling roller is to be reduced, the contact pressure of the scraper on the cold rolling roller must be reduced. Due to the reduction in pressure, some debris with greater adhesion cannot be effectively cleaned, which will reduce the cleaning effect of the cold rolling roller. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a self-adjusting roller cleaning device for a cold rolling mill, which utilizes a combination of a scraper and a grinding belt to clean the cold rolling roller. The scraping effect of the scraper can clean some hard debris, while the relative friction of the grinding belt can wipe and clean attached objects. At the same time, the contact between the grinding belt and the cold rolling roller is in a curved and fitted manner, and therefore has the characteristic of low pressure per unit area, thereby achieving an effective cleaning effect on the cold rolling roller and preventing scratching caused by excessive pressure, thereby solving the above-mentioned technical problems.

[0029] In order to achieve a combined cleaning effect of scraper and grinding belt on the cold rolling roller 7, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , it is necessary to set up a combined cleaning mechanism 10, which is provided with a rectangular hollow body 101 with a hollow interior, a grinding belt 1014 that can be wrapped around the upper half of the annular body of the cold rolling roller 7 and wipe the rotating cold rolling roller 7, and a strip scraper 1017 that can scrape the bottom area of ​​the cold rolling roller 7.

A first piston body is placed inside the first component active cavity 102 of the rectangular hollow body 101, which is capable of axial movement along the first component active cavity 102. 1011, the bottom end of the No. 1 piston body 1011 is fixedly installed with a No. 1 telescopic rod 1012 that passes through the No. 1 rod body through-hole 109, the No. 1 telescopic rod 1012 is sheathed with a No. 1 coil spring 1018 in a compressed state on the outer periphery of the rod body located inside the No. 1 component active cavity 102, the bottom end of the No. 1 telescopic rod 1012 is fixedly installed with a lower moving block 1013, and a closed grinding belt 1014 is embedded in the symmetrical sides of the lower moving block 1013, the rectangular hollow body 101 is placed inside the No. 2 component active cavity 108 with a No. 2 piston body 1015 that can move axially along the No. 2 component active cavity 108, the upper end of the No. 2 piston body 1015 is fixedly installed with a No. 1 coil spring 1018 that passes through the No. 1 component active cavity 102, and the No. 1 coil spring 1018 is sheathed with a No. 1 coil spring 1018 in a compressed state. A No. 2 telescopic rod 1016 passes through the No. 2 rod body through-hole 1010, and a strip scraper 1017 is fixedly installed on the top of the No. 2 telescopic rod 1016. The structural shape of the cross section of the No. 1 rod body through-hole 109 is consistent with the structural shape of the cross section of the No. 1 telescopic rod 1012, both of which are polygonal structures, and the structural dimensions of the cross section of the No. 1 rod body through-hole 109 match the structural dimensions of the cross section of the No. 1 telescopic rod 1012.

[0031] In order to prevent the hydraulic pressure from being too high and causing the strip scraper 1017 to scratch the cold roller 7, please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , it is necessary to set up an elastic decompression mechanism 11, which is provided with a longitudinal hollow shell 111 which is hollow inside and installed inside the rectangular hollow body 101, a movable valve plate 115 which can make the liquid flow in one direction from bottom to top, and a No. 2 coil spring 119 which exerts downward elastic pressure on the movable valve plate 115. When the liquid fills the No. 1 liquid flow hole 103 and the No. 1 component active cavity 102, it will flow upward. At this time, the liquid will generate an upward force on the movable valve plate 115. When the force is greater than the elastic pressure of the No. 2 coil spring 119, the liquid will flow along the No. 3 liquid flow hole 1 13. The moving gap of the movable valve plate 115, the liquid flow groove 116, the movable chamber 112 of the No. 3 component and the No. 4 liquid flow hole 114 flow into the movable chamber 108 of the No. 2 component, thereby driving the strip scraper 1017 to move upward. At the same time, due to the presence of the No. 2 coil spring 119, the liquid pressure in the movable chamber 108 of the No. 2 component can be made smaller than the liquid pressure in the movable chamber 102 of the No. 1 component, so that the wiping pressure is greater than the resistance pressure of the strip scraper 1017, thereby preventing the circulating hydraulic pressure from being too large and causing the strip scraper 1017 to scratch the cold rolling roller 7.
