Description

Technical Field

[0001] The invention relates to the technical field of copper strip rolling, in particular to a rolling mechanism for eliminating impurities from entering by mistake and application thereof in copper strip production. Background Art

[0002] The working principle of rolling is mainly to use the shear force and extrusion force between the rollers to increase the plasticity of the material after multiple extrusions and shearing, thereby extending it into a thin product. Different calenders may differ in their specific working principles and structures, but their basic principle is to use mechanical force to cause plastic deformation of metals or materials to achieve processing.

[0003] During the rolling process, the material is placed between two adjacent rollers. Due to the speed ratio and relative rotation between the rollers, the material is subjected to shearing and extrusion forces. The material at a suitable temperature and in a semi-fluid state is brought into the roller gap by the friction between the rollers. After multiple extrusions and shearing, the material is stretched into a thin product.

[0004] Therefore, when the copper strip is rolled, the above-mentioned method is also used for processing. In the actual production process, since certain metal impurities may remain on the surface of the copper strip and the roller, the impurities need to be cleaned. However, when the existing cleaning device is working, if the spacing between the rollers changes, the cleaning device cannot adaptively follow the movement of the rollers, and the cleaning force provided to the rollers and the copper strip will be insufficient, resulting in the problem that the impurities cannot be completely cleaned. The extrusion pressure provided by the rollers acts on the impurities, which will cause dents or damage on the surface of the copper strip, resulting in poor product quality.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0040] See also Figures 1 to 10 In an embodiment of the present invention, a rolling mechanism for eliminating impurities from entering by mistake includes: a truss 1, a lifting plate 2, a driving component, a first rolling roller 5, a reverse rotation mechanism, a second rolling roller 8, an impurity cleaning mechanism, a first cleaning roller 13, a second cleaning roller 16, a strength control component, and a winding component. In order to prevent the copper strip surface from being dented or damaged during the rolling process due to impurities remaining on the copper strip surface and the rolling roller surface, it is necessary to clean the impurities. When the driving component is working, it drives the first rolling roller 5 to rotate, and the driving component also drives the second rolling roller 8 to rotate through the reverse rotation mechanism, and the rotation direction of the second rolling roller 8 is opposite to that of the first rolling roller 5, so as to provide shearing force and extrusion force to the copper strip. During the rolling process, impurities The cleaning mechanism works and drives the first cleaning roller 13 and the second cleaning roller 16 to rotate to clean impurities on the copper strip and the surface of the rollers to ensure the best rolling quality of the copper strip. At this time, the copper strip will be extruded into the required thickness. After the extrusion is completed, the copper strip is wound up under the action of the winding assembly. If the rolling thickness of the copper strip needs to be adjusted, the spacing between the first roller 5 and the second roller 8 is adjusted by the reverse rotation mechanism under the action of the strength control assembly to achieve the effect of changing the rolling thickness of the copper strip. At the same time, when the spacing between the two rollers changes, under the action of the reverse rotation mechanism, it can be ensured that the transmission of the drive assembly remains smooth at all times, thereby achieving the effect of adjusting the rolling thickness of the copper strip according to production needs without stopping.

[0041] The details are as follows, including:

[0042] A truss 1, and a lifting plate 2 fixedly mounted on the truss 1 and symmetrically arranged;

[0043] Also includes:

[0044] See also Figure 1-Figure 3, a driving assembly is arranged on the truss 1, a first roller 5 is connected to the driving assembly, the driving assembly includes a first motor 3 fixedly mounted on the truss 1, a transmission rod 4 connected to the output shaft of the first motor 3 is rotatably mounted on the lifting plate 2, the transmission rod 4 is fixedly connected to the first roller 5, and a first gear 18 is fixed to the end of the transmission rod 4.

[0045] In detail, during the rolling process, the material is placed between two adjacent rollers. Due to the speed ratio and relative rotation between the rollers, the material is subjected to shear and extrusion forces. The material at a suitable temperature and in a semi-fluid state is brought into the gap between the rollers under the action of the friction between the rollers. After multiple extrusions and shearing, the material is extended into a thin product. In general, rolling is to force the material to be extruded and deformed by applying pressure and friction to obtain the desired shape and size. Different calenders may differ in their specific working principles and structures, but their basic principle is to use mechanical force to cause plastic deformation of metals or materials to achieve processing. Therefore, when rolling the copper strip, the copper strip can be placed between the first roller 5 and the second roller 8. At this time, the first motor 3 works and drives the transmission rod 4 to rotate, thereby driving the first roller 5 to rotate. At the same time, the transmission rod 4 will also drive the first gear 18 to rotate. Under the action of the first gear 18 and the reverse rotation mechanism, the second roller 8 rotates synchronously, and the rotation direction is opposite to that of the first roller 5. Under the action of the first roller 5 and the second roller 8, the copper strip is rolled.

[0046] See also Figure 1-Figure 6 , Fig. 9 , Fig.10The lifting plate 2 is provided with a reverse rotation mechanism connected to the driving component, and the reverse rotation mechanism is connected to a second roller 8. The driving component can drive the first roller 5 to rotate, and drive the second roller 8 to rotate in the reverse direction through the reverse rotation mechanism. The reverse rotation mechanism includes a slide groove 201 opened on the lifting plate 2, a sliding block 6 is slidably installed in the slide groove 201, a follower rod 7 is rotatably installed on the sliding block 6, and the follower rod 7 is fixedly connected to the second roller 8. The lifting plate 2 is provided with a toothing component connected to the follower rod 7, wherein the toothing component includes a toothed component rotatably installed on the lifting plate 2, a second gear 20 is fixed on the third rotating rod 19, and the second gear 20 is meshed with the first gear 18. A supporting structure connected with the follower rod 7 is provided on the lifting plate 2, and the supporting structure mentioned above includes a guide column 21 fixedly mounted on the lifting plate 2, a sliding sleeve 22 is slidably mounted on the guide column 21, and a spring 23 abutting against the sliding sleeve 22 is sleeved on the guide column 21; and also includes a guide wheel 24 rotatably mounted on the sliding sleeve 22, and the guide wheel 24 is sleeved with a second belt 25 connected with the follower rod 7 and the third rotating rod 19.

[0047] It should be noted that when the copper strip is rolled, the first roller 5 and the second roller 8 need to be controlled to rotate, and the rotation directions are opposite. In the initial state, the spring 23 is in a compressed state, so that the sliding sleeve 22 is located at the end of the stroke on the side of the guide column 21, so that the distance between the guide wheel 24 and the follower rod 7 is maximized. At this time, the second belt 25 is in a taut state to ensure that when the third rotating rod 19 rotates, the follower rod 7 can be driven to rotate by the second belt 25. Under the action of the strength control component, the sliding block 6 is located at the end of the stroke on the side of the slide groove 201 facing the truss 1, so that the distance between the first roller 5 and the second roller 8 is minimized. The first gear 18 is also driven by the transmission rod 4 to rotate. Since the first gear 18 and the second gear 20 are meshed, the third rotating rod 19 is controlled to rotate through the second gear 20, and the rotation direction of the third rotating rod 19 is the same as the rotation direction of the transmission rod 4. The third rotating rod 19 will drive the guide wheel 24 and the follower rod 7 to rotate through the second belt 25 to drive the second roller 8 to rotate in the opposite direction. At this time, the second roller 8 and the first roller 5 rotate synchronously and in opposite directions, thereby rolling the copper strip.

[0048] Preferably, if it is necessary to adjust the rolled thickness of the copper strip, it is necessary to adjust the spacing between the two rollers. At this time, under the action of the strength control component, the third rotating rod 19 is driven to move, thereby driving the sliding block 6 to move along the length direction of the slide groove 201 and move in the direction away from the truss 1, so that the spacing between the second roller 8 and the first roller 5 increases. When the third rotating rod 19 moves, it will drive the second belt 25 to move. Under the action of the tensioning force, the sliding sleeve 22 is driven by the guide wheel 24 to move along the length direction of the guide column 21 and move toward the follower rod 7, and the spring 23 is compressed, thereby ensuring that the second belt 25 will not be too tight or loose due to the change in the spacing between the follower rod 7 and the third rotating rod 19. Excessive tension may cause the second belt 25 to break, and looseness may cause the follower rod 7 to be unable to drive the rotation. Therefore, under the action of the spring 23 and the sliding sleeve 22, the position of the guide wheel 24 is adaptively adjusted to ensure the transmission effect of the second belt 25.

[0049] Among them, the transmission ratio of the first gear 18 and the second gear 20 is the same, and the transmission ratio of the third rotating rod 19 and the follower rod 7 is the same. Therefore, it can be ensured that the rotation speed of the first roller 5 and the second roller 8 is the same, so as to prevent the different extrusion pressure and friction force provided to the two sides of the copper strip due to the different rotation of the two rollers, resulting in friction scratches or damage on the surface of the copper strip.

[0050] See also Figure 1 , Figure 3-Figure 5 , Figure 7 , Figure 8 , an impurity cleaning mechanism is arranged on the lifting plate 2 and connected to the reverse rotation mechanism, the impurity cleaning mechanism is connected to a first cleaning roller 13 and a second cleaning roller 16, the impurity cleaning mechanism can drive the first cleaning roller 13 and the second cleaning roller 16 to rotate, the impurity cleaning mechanism includes a fixed sleeve 9 respectively fixedly mounted on the lifting plate 2 and the sliding block 6, a connecting plate 10 is fixed on the fixed sleeve 9, a second motor 11 is fixed on the connecting plate 10, a transmission assembly connected to the second motor 11 is provided on the connecting plate 10, wherein the transmission assembly includes a first rotating rod 12 and a second rotating rod 15 rotatably mounted on the connecting plate 10, the first rotating rod 12 is fixedly connected to the first cleaning roller 13, and is connected to the output shaft of the second motor 11, the second rotating rod 15 is fixedly connected to the second cleaning roller 16, and the first rotating rod 12 is sleeved with a first belt 14 connected to the second rotating rod 15.

[0051] Furthermore, since certain impurities may remain on the surface of the copper strip during transportation, these impurities may cause the surface of the copper strip to dent or be damaged under the action of the roller squeezing force when it moves to the position in contact with the surface of the roller. Therefore, it is necessary to clean the copper strip and the surface of the roller. The partition 17 is located between the two cleaning rollers, and a scraper 1701 is fixed to the end of the partition 17. The end of the scraper 1701 is in contact with the surface of the roller. Cleaning rollers are provided on the first roller 5 and the second roller 8. In the initial state, the two first cleaning rollers 13 are in contact with the surfaces of the first roller 5 and the second roller 8, respectively. The second cleaning roller 16 is respectively located on the upper and lower sides of the copper strip. When the first roller 5 and the second roller 8 rotate, the copper strip is rolled. At the same time, the second motor 11 works and drives the first rotating rod 12 to rotate, thereby driving the first cleaning roller 13 to rotate. Under the action of the motor 11, the rotation direction of the first cleaning roller 13 is opposite to that of the rolling roller, so that the impurities remaining on the surface of the rolling roller are cleaned out by the first cleaning roller 13. At the same time, the first rotating rod 12 will also drive the second rotating rod 15 to rotate through the first belt 14, so as to synchronously clean the two sides of the copper belt through the second cleaning roller 16. Under the action of the cleaning roller, the impurities remaining on the copper belt and the rolling roller will be detached, and under the action of the partition 17, it is ensured that the impurities will not return to the copper belt and the rolling roller. At the same time, since the scraper 1701 is in contact with the surface of the rolling roller, under the action of the scraper 1701, the residual impurities that cannot be cleaned by the cleaning roller can be scraped off. Among them, the cleaning brush that is in contact with the surface of the copper belt has a cleaning direction in the opposite direction of the moving direction of the copper belt. Therefore, it can be ensured that the impurities swept away by the cleaning roller during the cleaning process will not splash onto the surface of the rolling roller.

[0052] Preferably, if the distance between the two rollers needs to be adjusted, the position of the sliding block 6 will change, and the sliding block 6 will also drive one of the fixed sleeves 9 to move to ensure that the cleaning roller cooperating with the second roller 8 moves synchronously with the roller, thereby ensuring that when the position of the roller changes, the cleaning brush can always provide a cleaning effect on the copper strip and the roller surface.

[0053] See also Figure 1 , Figure 4 , a strength control component is arranged on the lifting plate 2 and connected to the reverse rotation mechanism. The strength control component can adjust the distance between the second roller 8 and the first roller 5 through the reverse rotation mechanism. The strength control component includes a rotating sleeve 26 rotatably mounted on the follower rod 7, and a cylinder 27 fixedly connected to the rotating sleeve 26 is fixed on the lifting plate 2.

[0054] Furthermore, in order to meet production needs, it is usually necessary to adjust the spacing between the rollers to ensure that the thickness of the copper strip rolled meets the required requirements. In the initial state, under the action of the cylinder 27, the sliding block 6 is located at the end of the stroke on one side of the slide 201 and is facing the truss 1. When the thickness of the copper strip needs to be increased, under the action of the cylinder 27, the follower rod 7 is driven to move by rotating the sleeve 26, thereby controlling the sliding block 6 to move along the length direction of the slide 201 and move in the direction away from the truss 1 to increase the spacing between the rollers. After the adjustment is completed, under the action of the cylinder 27, ensure that the spacing between the rollers remains unchanged.

[0055] See also Figure 1 , Figure 2 , also includes a winding assembly arranged on the lifting plate 2, the winding assembly is arranged on the lifting plate 2, and is used to wind up the rolled plate, the winding assembly includes a receiving plate 28 fixedly mounted on the lifting plate 2, a third motor 29 is fixed on the receiving plate 28, a winding roller 30 is rotatably mounted on the receiving plate 28, and the rotating shaft of the winding roller 30 is connected to the output shaft of the third motor 29.

[0056] To elaborate, after the copper strip is rolled, it is necessary to reel it. At this time, the rolled copper strip can be wound around the reel 30. At the same time, under the action of the third motor 29, the reel 30 is controlled to rotate, so as to reel the copper strip. When the thickness of the copper strip wound around the reel 30 reaches a certain level, the reel 30 can be removed from the receiving plate 28 and replaced with a new reel 30 to ensure continuous reeling of the copper strip.
