[0023] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0024] like Figure 1-6 As shown, an ultra-thin steel strip rolling device includes a top material roller assembly and an upper roller body 1 and a lower roller body 2 for rolling the steel strip; the top material roller assembly is located downstream of the upper roller body 1 and the lower roller body 2 along the conveying direction of the steel strip; the top material roller assembly includes a top material roller 3, the lower edge height of the top material roller 3 is lower than the upper edge height of the lower roller body 2, and a plurality of top material columns 30 are provided on the outer peripheral wall of the top material roller 3, and the top material columns 30 are elastically slidably arranged along the radial direction of the top material roller 3.

[0025] The upper roller body 1 and the lower roller body 2 are used to punch holes in the steel strip, and the lower roller body 2 can be specifically an active roller, that is, directly connected to a power device such as a motor. The upper roller body 1 and the lower roller body 2 are already common in the steel strip rolling industry and are prior art. Their specific structure and working principle will not be repeated in this embodiment.

[0026] A top-feeding roller assembly is provided on the downstream side of the upper roller body 1 and the lower roller body 2, i.e., the side where the steel belt is transported after the cavity is formed. The top-feeding roller 3 in the top-feeding roller assembly can rotate freely. Specifically, the rotation of the top-feeding roller 3 is achieved through friction with the steel belt. When the waste sheet in the circular hole on the steel belt does not fall off when the circular hole is formed, it will reach the position of the top-feeding roller 3 as the steel belt runs.

[0027] When the ejection column 30 just abuts the circular hole, the waste pieces that have not fallen off will be ejected out of the circular hole under the action of the ejection column 30; when the ejection column 30 does not abut the circular hole, the steel belt will compress the ejection column 30 into the interior of the ejection roller 3, and the elastic action of the ejection roller 3 can also increase the friction between the steel belt and the ejection roller 3 to drive the ejection roller 3 to rotate, so that different ejection columns 30 can push the waste pieces in the circular holes.

[0028] The ejection columns 30 on the ejection roller 3 are arranged relatively densely to fully ensure that the circular holes on the steel strip can be covered.

[0029] Under the action of the ejecting roller 3, the waste pieces remaining on the round holes in the steel strip can be ejected by the ejecting pieces, and the ejecting roller 3 rotates continuously throughout the whole process, and the steel strip does not need to move intermittently, thereby improving the continuity of the whole rolling process and thus improving production efficiency.

[0030] In some further embodiments, a cylindrical sliding groove is provided on the outer peripheral wall of the ejection roller 3, the axial direction of the cylindrical sliding groove is consistent with the radial direction of the ejection roller 3, a fixed column 300 is provided on the end face of one end of the ejection column 30 located inside the cylindrical sliding groove, a mounting hole is provided at the bottom of the cylindrical sliding groove, the fixed column 300 is arranged through the mounting hole, and a stop handle 301 is provided at one end of the fixed column 300 passing through the mounting hole; a first spring 33 is sleeved on the fixed column 300, one end of the first spring 33 abuts against one end of the ejection column 30, and the other end of the first spring 33 abuts against the bottom of the cylindrical sliding groove.

[0031] When the ejector column 30 does not abut the circular hole in the steel strip, the ejector column 30 slides in the columnar sliding groove 32 toward the axis of the ejector roller 3 . At this time, the first spring 33 is compressed until the ejector column 30 is completely compressed into the columnar sliding groove 32 .

[0032] When the ejector column 30 abuts against the circular hole in the steel strip, the elastic force applied to the ejector column 30 by the first spring 33 is greater than the "adhesion" force between the waste piece remaining in the circular hole and the edge of the circular hole, thereby ejecting the waste piece. It should be noted that the diameter of the ejector column 30 is smaller than the inner diameter of the circular hole to ensure that there is no interference with the edge of the circular hole during the ejection process.

[0033] In some further embodiments, a first support seat 31 is further included, a first rotating shaft is provided on the top of the first support seat 31, and the top material roller 3 is arranged on the first rotating shaft.

[0034] The rotation of the top material roller 3 is realized by the first rotating shaft and the first supporting seat 31 , and the two ends of the first rotating shaft are rotatably arranged on the two side walls of the first supporting seat 31 .

[0035] In some further embodiments, an adjustment frame 4 is also included, on which an adjustment plate 40 is provided, on which an adjustment stud 41 is slidably penetrated, and one end of the adjustment stud 41 located at the bottom of the adjustment plate 40 is provided with a U-shaped handle 10, and the lower end of the adjustment stud 41 slides through the bottom wall of the U-shaped handle 10, and four adjustment bolts 42 are screwed on the adjustment stud 41, two of which are respectively located on both sides of the adjustment plate 40 and respectively abut against the two side walls of the adjustment plate 40, and the other two are respectively located on both sides of the bottom wall of the U-shaped handle 10 and respectively abut against the bottom wall of the U-shaped handle 10; a second rotating shaft is provided on the two side walls of the U-shaped handle 10, and the upper roller body 1 is arranged on the second rotating shaft.

[0036] By controlling the adjusting bolts 42, the upper roller body 1 can be adjusted up and down, that is, the two adjusting bolts 42 on both sides of the adjusting plate can be adjusted, and the adjusting bolts 42 on both sides of the bottom wall of the U-shaped plate can also be adjusted.

[0037] The rotation support of the upper roller body 1 is realized by the U-shaped handle 10 and the second rotating shaft. The end of the second rotating shaft is rotatably arranged on the two side walls of the U-shaped handle 10, and the upper roller body 1 is arranged on the second rotating shaft.

[0038] The lower roller body 2 is located directly below the upper roller body 1, and the rotation support of the lower roller body 2 can be achieved through the second support seat 20. The second support seat 20 has a similar structure to the first support seat 31. A third rotating shaft is rotatably arranged in the second support seat 20, and both ends of the third rotating shaft are rotatably arranged on the two side walls of the second support seat 20. Under the action of the third rotating shaft and the second support seat 20, the rotation of the lower roller body 2 is jointly achieved.

[0039] In some further embodiments, the adjusting stud 41 and the adjusting plate 40 and the bottom wall of the U-shaped handle 10 are arranged to prevent rotation.

[0040] Since the adjustment of the upper roller body 1 is achieved through the adjusting stud 41 and the adjusting bolt 42, in order to prevent the upper roller body 1 from twisting, a stop is specially provided for the adjusting stud 41, that is, a first stop plane 410 is provided on the adjusting stud 41, and a corresponding second stop plane 400 is provided in the hole for passing the adjusting stud 41 on the corresponding adjusting plate 40 and the bottom wall of the U-shaped handle 10, so that the stop stud can only move axially relative to the adjusting plate 40 and the U-shaped handle 10 but not in a circular motion, thereby ensuring the accuracy of the cooperation between the upper roller body 1 and the lower roller body 2.

[0041] The entire device also includes a discharge roller and a feed roller, the discharge roller is wound with a steel strip to be formed, and the feed roller is wound with a steel strip formed with round holes. It should be expected that the discharge roller and the feed roller are located between all the mechanisms for structuring the steel strip.

[0042] In some further embodiments, a rolling mechanism 53 is further included, which includes a first rotating wheel 50, a second rotating wheel 51, a conveyor belt 52 sleeved on the first rotating wheel 50 and the second rotating wheel 51, and a support platform 6 for supporting the steel belt; the support platform 6 is located below the conveyor belt 52.

[0043] Since the steel strip is wound on the feed roller for a long time, the steel strip wound off the feed roller will have a certain curvature. In order to avoid the process of punching holes in the steel strip caused by the curvature, a flattening mechanism 53 is specially provided to perform flattening pretreatment on the steel strip.

[0044] Specifically, the flattening is achieved through the conveyor belt 52 and the support platform 6. The conveyor belt 52 is supported and driven by the first rotating wheel 50 and the second rotating wheel 51. When the steel belt passes through the gap between the support platform 6 and the conveyor belt 52, it is pressed by the conveyor belt 52, thereby making it flatter to a certain extent.

[0045] In some further embodiments, the rolling mechanism 53 further includes a support frame 5 , and the first rotating wheel 50 and the second rotating wheel 51 are both rotatably disposed on the support frame 5 .

[0046] Specifically, the first rotating wheel 50 and the second rotating wheel 51 are both rotatably disposed on the support frame 5 .

[0047] In some further embodiments, a mounting plate is provided on the support frame 5, and the mounting plate is located between two layers of the conveyor belt 52, and pressure roller groups are elastically provided on both sides of the mounting plate.

[0048] In order to ensure the flattening effect, a pressure roller group is elastically arranged between the two layers of the conveyor belt 52, that is, between the upper layer and the lower layer of the conveyor belt 52.

[0049] Specifically, the pressing roller group is elastically arranged on a mounting plate, and the mounting plate is arranged on the supporting frame 5 .

[0050] A mounting sleeve 7 is provided on the side wall of the mounting plate, and a sliding hole is provided on the cross section of one end of the mounting sleeve 7 away from the mounting plate; the pressure roller group includes a plurality of pressure roller columns 530 arranged at intervals on the frame, and the plurality of pressure roller columns 530 are rotatably set on the frame, and a sliding rod 70 is provided on the pressure roller column 530, and the sliding rod 70 is slidably set in the sliding hole, and a limiting handle 71 is provided at one end of the sliding rod 70 located inside the mounting sleeve 7, and a second spring 72 is provided in the mounting sleeve 7, and one end of the second spring 72 abuts against a part of the mounting plate located inside the mounting sleeve 7, and the other end of the second spring 72 abuts against the limiting handle 71, so as to realize the elastic movement of the pressure roller group.

[0051] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
